Abstract
The utility model discloses a plug pin rod, which comprises a pin rod (3). A wedge (6) is arranged in the pin head (5) of the pin rod (3), arranged in a groove (51) of the pin head (5), connected with the top end of the groove (51) through a spring (4), and provided with two positioning convex edges (61) and (62) the sizes of the two positioning convex edges (61) and (62) are matched with the groove (51), and the wedge (6) is movably connected with the groove (51) of the pin head (5). The utility model has the advantages that the structure that the movable wedge is arranged in the pin head not only not influences the convenience for opening and closing doors and windows, but also overcomes the noise problem, and solves the problems existing in the prior art. After the plug pin rod is used, no gap exists between the plug pin rod and the door and window frames, and therefore the doors and windows do not get loose and generate noise during wind blowing and raining outside the rooms.
Description
Technical field
The utility model relates to a kind of bolt rod.
Background technology
Under normal conditions, the little pin hole of thumb-latch bar, Switch for door and window could be comparatively smooth, but bolt rod and pin hole have the space promptly loosening, it is of a specified duration that door and window uses, and it is increasing that understand in bolt rod and friction gap, hole, as run into the external world and expose to wind and rain, door and window will produce noise, influence the atmosphere in whole room, the user can suspect the quality of door and window, how to allow Switch for door and window convenient, door and window is not produced because the noise that bring in increasing gap becomes the problem that our urgent need will solve.
Summary of the invention
The utility model provides a kind of bolt rod at deficiency of the prior art, overcomes shortcoming in the prior art, by in the pin head, being provided with movable voussoir, this structure neither influences the convenience of the switch of door and window, overcomes the problem of noise again, has solved problems of the prior art.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of bolt rod comprises pin rod, is provided with voussoir in the pin head of described pin rod, voussoir is located in the groove of pin head, and voussoir is connected by spring with the top of groove, and voussoir is provided with twice location chimb, the size and the groove of twice location chimb are complementary, and the groove of voussoir and pin head flexibly connects.
Described voussoir is made of cuboid and triangle cone, and the triangle cone is arranged on the top of cuboid.
The beneficial effects of the utility model: by in the pin head, being provided with movable voussoir, this structure neither influences the convenience of the switch of door and window, overcome the problem of noise again, problems of the prior art have been solved, after using this bolt rod, do not have the space between bolt rod and the doorframe and window frame, extraneous exposes to wind and rain, and door and window does not have a bit loosening and noise.

The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
Shown in Fig. 1,2,3,4,5, a kind of bolt rod, comprise pin rod 3, be provided with voussoir 6 in the pin of described pin rod 35, voussoir 6 is located in the groove 51 of pin head 5, voussoir 6 is connected by spring 4 with the top of groove 51, voussoir is provided with twice location chimb 61,62, the size and the groove 51 of twice location chimb 61,62 are complementary, as shown in Figure 3, voussoir 6 flexibly connects with the groove 51 of pin head, and described voussoir is made of cuboid and triangle cone, the triangle cone is arranged on the top of cuboid, and the remaining both sides of cuboid are as the location chimb.
During use, in the pin hole 1 on the doorframe and window frame 2 that the bolt rod insertion is fixing, when the pin of pin rod 35 during less than pin hole 1, pin 5 mainly leans on voussoir 6 to remedy with the space between the pin hole 1, spring 4 between voussoir 6 and the groove 51 plays an effect of adjusting voussoir 6, promptly the crack between pin 5 and the pin hole 1 is big, then voussoir 6 is far away more from the bottom of groove 51, big as the crack between pin head 5 and the pin hole 1, then voussoir 6 is near more from the bottom of groove 51, and voussoir 6 plays a fastening effect here, does not have the space between bolt rod and the doorframe and window frame 2, extraneous exposes to wind and rain, and door and window does not have a bit loosening and noise.
Claims (2)
1. bolt rod, comprise pin rod (3), it is characterized in that being provided with voussoir (6) in the pin head (5) of described pin rod (3), voussoir (6) is located in the groove (51) of pin head (5), voussoir (6) is connected by spring (4) with the top of groove (51), voussoir (6) is provided with twice location chimb (61), (62), and the size and the groove (51) of twice location chimb (61), (62) are complementary, and voussoir (6) flexibly connects with the groove (51) of pin head (5).
