Description
Technical field
The present invention relates to a kind of EXPANSION ANCHOR BOLTS, specifically a kind of two all can be used for being fixed on the EXPANSION ANCHOR BOLTS on other object.
Background technique
Setscrew is generally all made up of two parts, an activity, fixes for one, under the effect of external force, two parts relative motion, make the local of activity or fixing parts deform, volume becomes large, becomes also larger than the internal diameter in hole, thus produces coupling mechanism force.
EXPANSION ANCHOR BOLTS on market has a variety of, all in order to certain specific occasion uses, as road surface, metope or thin plate etc., and this use is all recoverable, with expanding when being threaded into and fixing, expand when screw thread screws out and disappear, movable part can depart from from fixed component; Can not restore after seldom having use.
But there are some occasions can only use not recoverable EXPANSION ANCHOR BOLTS, can only destroy by force, as the transport vehicle for deliver goods, for sending the mainframe parcel etc. of express delivery, preventing midway from being opened by people, stealing article, can only open in destination, can only single use.
Summary of the invention
The present invention is directed to prior art deficiency, provide one not recoverable, two can be two fixed expansion bolt of iron chains or rope.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: two fixed expansion bolt, comprise outer sleeve and interior bar, described outer sleeve front end is provided with the front port expanded outwardly, the rear end of described outer sleeve is provided with rear horn mouth, the centre of described outer sleeve is provided with several opening, described interior bar comprises front drift, intermediate bar and rear plug, the diameter of described front drift is less than the internal diameter of described outer sleeve, the diameter of described rear plug is greater than the internal diameter of described outer sleeve, described intermediate bar is provided with several barb pieces, described barb piece is arranged in described opening, described front drift is arranged in described front port, described rear plug is against described rear horn mouth.
Described outer sleeve is provided with beam tube portion, described beam tube portion is arranged on the rear side of described front port, described front port is provided with several front end breaches, described front end breach extends to described beam tube portion, described rear horn mouth is provided with several rear end breaches.
Described front drift is provided with portion with a tight waist, and the described portion with a tight waist described in the clamping of beam tube portion, the minimum outer diameter in described portion with a tight waist is greater than the minimum diameter in described beam tube portion.
Described rear plug is provided with rounding, and described rounding is against described rear horn mouth.
The front end of described interior bar is provided with front hook, and described front hook arranges the front of described front drift, and the rear end of interior bar is provided with rear hook, and described rear hook is arranged on the rear of described rear plug.
The present invention compared with prior art, has following beneficial effect: 1, barb piece contacts with the inwall in the hole of sheet material after protruding opening, plays and expands and the effect fixed; 2, portion with a tight waist is stuck in beam tube portion, front port is split and expands, being greater than the internal diameter in the hole of sheet material, playing fixation; 3, rear plug is stuck in rear horn mouth, makes rear horn mouth split and expand, and get lodged on the other end hole in the hole of sheet material, front port coordinates with rear horn mouth, outer sleeve can be fixed on sheet material, can not be shifted; 4, beam tube portion clamping portion with a tight waist, makes interior bar to be subjected to displacement; 5, this EXPANSION ANCHOR BOLTS is disposable, can only violence damage after loading onto.
Accompanying drawing explanation
Fig. 1 is the product structure exploded perspective view of the embodiment of the present invention.
Structural representation when Fig. 2 is the loading of the embodiment of the present invention.
Structural representation when Fig. 3 is the installation of the embodiment of the present invention.
Embodiment
Be described in further detail the present invention below in conjunction with accompanying drawing and embodiment: as shown in Figure 1, Figure 2 and Figure 3, in figure, mark is as follows: outer sleeve 1, interior bar 2, front port 3, rear horn mouth 4, opening 5, front drift 6, intermediate bar 7, rear plug 8, barb piece 9, beam tube portion 10, portion 11 with a tight waist, rounding 12, front hook 13, rear hook 14.
Two fixed expansion bolt, it comprises outer sleeve 1 and interior bar 2, outer sleeve 1 front end is provided with the front port 3 expanded outwardly, the rear end of outer sleeve 1 is provided with rear horn mouth 4, the centre of outer sleeve 1 is provided with multiple opening 5, interior bar 2 comprises front drift 6, intermediate bar 7 and rear plug 8, the diameter of front drift 6 is less than the internal diameter of outer sleeve 1, the diameter of rear plug 8 is greater than the internal diameter of outer sleeve 1, intermediate bar 7 is provided with multiple barb piece 9, barb piece 9 is arranged in opening 5, and front drift 6 is arranged in front port 3, and rear plug 8 is against rear horn mouth 4.
Outer sleeve 1 is provided with beam tube portion 10, beam tube portion 10 is arranged on the rear side of front port 3, front port 3 is provided with multiple front ends breach (not shown), be convenient to front port 3 craze and transfiguration, front end breach (not shown) extends to beam tube portion 10, rear horn mouth 4 is provided with multiple rear ends breach (not shown), is convenient to rear horn mouth 4 craze and transfiguration.
