Abstract
The utility model discloses a connecting pin for building templates, including connecting the shank, at the internal cavity that is equipped with of connecting pin, point portion connecting the shank is equipped with vertical through -hole, vertical through -hole is linked together with the cavity, be equipped with the piston baffle and support the depression bar in the cavity, support the top and piston baffle looks butt of depression bar, the bottom activity of supporting the depression bar sets up in vertical through -hole, be equipped with the sealed smooth layer of leading between the inner wall of piston baffle and cavity, top connecting the shank is equipped with the gas injection mouth that is linked together with the cavity, be equipped with the buffer spring that resets between depression bar and vertical through -hole. The utility model has the advantages of simple structure, convenient to use is swift, and it not only can effectually be used manpower sparingly and material resources, but also can effectually prevent the template damage, has saved use cost to a certain extent, and the suitability is good, and the practicality is strong.
Description
Technical field
The utility model belongs to building implements technical field, is specifically related to a kind of connecting pin for construction formwork.
Background technology
Mostly use construction formwork is had in current construction work, these construction formworks are generally be connected by screw in use, although it effectively can realize the connection of template, but it is comparatively numerous and diverse when using rear dismounting, and easily damage template, affect reusing of template, so adds somewhat to use cost, applicability and practicality are restricted to a certain extent, and dismounting is comparatively inconvenient.
Summary of the invention
In order to solve the problems of the technologies described above, it is simple that the utility model is to provide a kind of structure, the convenient and connecting pin for construction formwork that stability in use is good of dismounting.
The technical scheme realizing the utility model object is a kind of connecting pin for construction formwork, comprise connection shank, cavity is provided with in described connection shank, vertical through holes is provided with in the tip of described connection shank, described vertical through holes is connected with described cavity, in described cavity, be provided with piston baffle and compress bar, described compress bar top and described piston baffle abut against, the described bottom compressing bar is movably arranged in described vertical through holes, be provided with between described piston baffle and the inwall of described cavity and seal slide guide layer, the air injection opening be connected with described cavity is provided with on the top of described connection shank, reset buffer spring is provided with described compressing between bar and described vertical through holes.
Also be provided with at described connection shank the sealing matched with described air injection opening to block.
Described vertical through holes is two and is symmetrical arranged, described in compress bar and be two and be separately positioned in two vertical through holes.
The described end compressing bar is that plane is arranged.
The utility model has positive effect: structure of the present utility model is simple, convenient to use, upon connection when needs take off, use inflator pump to inflate in air injection opening, piston baffle is moved down thus drives to compress bar and stretch out connection shank, thus connection shank is extruded under reaction force in template, it not only can effectively save manpower and material resources, but also effectively can prevent damaged template, saves use cost to a certain extent, applicability is good, practical.
Accompanying drawing explanation
In order to make content of the present utility model be more likely to be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
(embodiment 1)
Fig. 1 shows a kind of detailed description of the invention of the present utility model, and wherein Fig. 1 is structural representation of the present utility model.
See Fig. 1, a kind of connecting pin for construction formwork, comprise and connect shank 1, cavity 2 is provided with in described connection shank 1, vertical through holes 3 is provided with in the tip of described connection shank 1, described vertical through holes 3 is connected with described cavity 2, in described cavity 2, be provided with piston baffle 4 and compress bar 5, described compress bar 5 top and described piston baffle 4 abut against, the described bottom compressing bar 5 is movably arranged in described vertical through holes 3, be provided with between described piston baffle 4 and the inwall of described cavity 2 and seal slide guide layer 6, the air injection opening 7 be connected with described cavity 2 is provided with on the top of described connection shank 1, reset buffer spring 8 is provided with described compressing between bar 5 and described vertical through holes 3.
Also be provided with at described connection shank 1 sealing matched with described air injection opening 7 and block 9.
Described vertical through holes is two and is symmetrical arranged, described in compress bar and be two and be separately positioned in two vertical through holes.
The described end compressing bar is that plane is arranged.
The utility model has positive effect: structure of the present utility model is simple, convenient to use, upon connection when needs take off, use inflator pump to inflate in air injection opening, piston baffle is moved down thus drives to compress bar and stretch out connection shank, thus connection shank is extruded under reaction force in template, it not only can effectively save manpower and material resources, but also effectively can prevent damaged template, saves use cost to a certain extent, applicability is good, practical.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And these belong to connotation of the present utility model the apparent change of extending out or variation still belong to protection domain of the present utility model.
