Abstract
The invention discloses a marking head device. The marking dead device comprises a marking head, lead rails and sliding blocks, wherein marking holes are formed on the marking head, and sealing rings are distributed above the marking holes; two lead rails are arranged on the marking head, and distributed at two sides of the marking holes, respectively; guide grooves are arranged on the lead rails; the sliding blocks can be arranged on the lead rails by means of slipping; sliding devices arranged in the guide grooves are arranged at two sides of the sliding blocks; and when the sliding devices are slipped to the bottom positions of the guide grooves, the sealing rings can be compressed by the sliding blocks. The marking head device is out of the limitation from a solenoid valve and a relay, and requires the limitation of the sliding blocks and the sliding devices for achieving the purpose of sealing the marking holes. With the adoption of the marking head device, the problems caused by accident pressure leakage can be avoided, for example, high temperature gas quickly leaks from a burned component.
Description
Technical field
The present invention relates to sampling device technical field, more particularly, relate to the one sample head unit that falls.
Background technology
At present, the sampling device that falls mostly on the market is by fall sample head, slide block and the sample dish that falls and forms, slide block advances and drives sample dish to rotate, the sample dish that falls relies on gravity to fall next sample, after falling into slide block, fall into sample head, then slide block retreats again, and slider bottom has a pneumatic sealing device containing sealing ring, after air pressure, tightly push down the sample hole surrounding that falls on sample head being filled with, the space of realizing sample head bottom is isolated from the outside.
But, here there are two problems, the sealing of slide block needs pneumatic means (when the sample dish that falls completes after sampling, the sample hole that falls is carried mechanism sealing by the pneumatic sample head that falls), and the sample head that falls carries mechanism and needs circuit (magnetic valve and relay) to realize the switching over of source of the gas; The secondth, once that the external environment condition of sealing device occurs is abnormal, as having a power failure or tripping operation can cause sealing device to lose sealing property, need the space of sealing may occur that unexpected pressure release causes other problem, as high-temperature gas is overflowed and burnt out parts etc. fast.
Therefore, how to avoid occurring that unexpected pressure release causes that effusion as quick in high-temperature gas burns out the problem of parts, becomes those skilled in the art's technical problem urgently to be resolved hurrily.
Summary of the invention
In view of this, the invention provides the one sample head unit that falls, overflow fast and burn out the problem of parts to avoid occurring that unexpected pressure release causes as high-temperature gas.
For achieving the above object, the invention provides following technical scheme:
The one sample head unit that falls, comprising:
The sample head that falls, described in fall on sample head to offering sample hole, described in the top, sample hole that falls be furnished with sealing ring;
The guide rail falling described in being arranged on sample head, described guide rail is two, the both sides in the sample hole that falls described in being arranged in respectively, described guide rail is provided with gathering sill;
Be mounted slidably the slide block on described guide rail, the both sides of described slide block have the carriage being arranged in described gathering sill, and the extreme lower position that described carriage slides into described gathering sill can make described slide block compress described sealing ring.
Preferably, above-mentioned fall in sample head unit, described sealing ring is O RunddichtringO.
Preferably, above-mentioned fall in sample head unit, described carriage is bearing, road wheel or rolling bearing pin.
Preferably, above-mentioned fall in sample head unit, the height of described carriage is identical with the height of described gathering sill.
Preferably, above-mentioned fall in sample head unit, described in described guide rail is fixed on by guide rail hold-down screw, fall on sample head.
Preferably, above-mentioned fall in sample head unit, described slide block slides by air cylinder driven.
Preferably, above-mentioned fall in sample head unit, the described carriage that is arranged at described each side of slide block is at least two.
Can find out from above-mentioned technical scheme, provided by the invention fall sample head unit, in the time that slide block retreats, carriage on slide block slips into its lowest position of the gathering sill of guide rail, take up slide block and down move, slider bottom pushes down sealing ring on sample head, realizes the effect that seals sample hole; When slide block advances, the carriage on slide block skids off the extreme lower position of gathering sill, takes up slide block and up moves, and slider bottom no longer pushes down sealing ring on sample head.The present invention is not subject to the restriction of magnetic valve and relay, but needs the position-limiting action of chute and carriage to realize the object that seals sample hole, and the present invention has avoided occurring that unexpected pressure release causes that effusion as quick in high-temperature gas burns out the problem of parts.
Brief description of the drawings
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The structural representation of the sample head unit that falls that Fig. 1 provides for the embodiment of the present invention;
Fig. 2 is the top view of Fig. 1.
Detailed description of the invention
The invention discloses the one sample head unit that falls, overflow fast and burn out the problem of parts to avoid occurring that unexpected pressure release causes as high-temperature gas.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Refer to Fig. 1, the structural representation of the sample head unit that falls that Fig. 1 provides for the embodiment of the present invention.
What the embodiment of the present invention provided fall sample head unit, comprises falling sample head 1, guide rail 2 and slide block 3.
Wherein, on the sample head 1 that falls, offer sample hole, the top, sample hole that falls is furnished with sealing ring 6, realizes the sealing in sample hole by sealing circle 6.Guide rail 2 is arranged on sample head 1, and guide rail 2 is two, is arranged in respectively the both sides in sample hole, and guide rail 2 is provided with gathering sill.
Slide block 3 is mounted slidably on guide rail 2, and the both sides of slide block 3 have the carriage 7 being arranged in gathering sill, and the extreme lower position that carriage 7 slides into gathering sill can make slide block 3 press seal circles 6.In the time that carriage 7 slides into the extreme lower position of gathering sill, slide block 3 can move down, then press seal circle 6.
