By adopting the technical scheme, the flange is hexagonal and is convenient to limit the flange by using the wrench, so that the flange rotates together when the bolt is prevented from being screwed in, and the expansion head is ejected out from the rivet main body after the bolt is screwed in.
Further, the diameter of the mandrel is equal to the diameter of the inner ring of the threaded sleeve.
Through adopting above-mentioned technical scheme, the bolt is screwed in the back expansion head and is ejected to break away from the rivet main part to make the expansion end structural strength of rivet main part reduce and can produce deformation, later pull out the rivet main part with hard and make the rivet main part expansion end reduce alright.
Further, the flange is fixedly connected with the rivet body.
By adopting the technical scheme, the flange is hexagonal and is convenient to limit the flange by using the wrench, so that the flange rotates together when the bolt is prevented from being screwed in, and the expansion head is ejected out from the rivet main body after the bolt is screwed in.
Further, the mandrel is fixedly connected with the expansion head, and the diameter of the expansion head is equal to that of the rivet main body.
Through adopting above-mentioned technical scheme, pass the through-hole with the rivet main part and utilize the instrument to take out the dabber, make the expansion head shrink in the rivet main part after the dabber atress to make rivet main part one end inflation, make rivet main part one end diameter be greater than the through-hole diameter.
Further, through holes are formed in the first mounting plate and the second mounting plate, and the rivet main body and the expansion head are matched with the through holes.
Through adopting above-mentioned technical scheme, merge first mounting panel and second mounting panel to make the through-hole on two mounting panels correspond each other, later the staff passes the through-hole with the rivet main part and utilizes the instrument to take out the dabber, thereby fixes both.
In summary, the utility model has the following advantages:
1. According to the utility model, through the arrangement of the flange, the thread bush and the bolt, when the rivet is required to be disassembled, the bolt can be screwed into the rivet through the arrangement of the thread bush, meanwhile, the flange is hexagonal so as to be convenient for limiting the flange by using a spanner, the flange is prevented from rotating together when the bolt is screwed in, and the expansion head is ejected out from the rivet main body after the bolt is screwed in, so that the structural strength of the expansion end of the rivet main body is reduced and deformation can be generated, and then the rivet main body is pulled out forcefully to reduce the expansion end of the rivet main body, so that the production cost is low, and the disassembly is simple and quick.

Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the utility model.
Hereinafter, an embodiment of the present utility model will be described in accordance with its entire structure.
The utility model provides an easy detachable car rivet, as shown in figures 1, 2,3 and 4, including rivet main part 1, first mounting panel 7 and bolt 9, rivet main part 1 inside top is provided with the thread bush 5 that is used for screwing in bolt 9, rivet main part 1 top is connected with the flange 2 that is used for spacing, the width of flange 2 is greater than the diameter of rivet main part 1, and flange 2 is the hexagon, so that the spanner is spacing with the flange, it has dabber 3 that extends to rivet main part 1 bottom to run through in the middle of the flange top, dabber 3 one end is connected with the expansion head 4 that is used for spacing, guide slot 6 that is used for guiding the fracture position has been seted up to dabber 3 surface, low in production cost, dismantle simple and fast.
Referring to fig. 3 and 4, in the above embodiment, the first mounting plate 7 is located on the surface of the rivet main body 1, the bottom of the first mounting plate 7 is connected with the second mounting plate 8, through holes are formed in the tops of the first mounting plate 7 and the second mounting plate 8, and the rivet main body 1 and the expansion head 4 are matched with the through holes, so that the parts of the frame are conveniently assembled and fixed.
Referring to fig. 1, 2, 3 and 4, in the above embodiment, the diameter of the mandrel 3 is equal to the diameter of the inner ring of the thread bush 5, the flange 2 is fixedly connected with the rivet body 1 in an integrally formed manner, the mandrel 3 is fixedly connected with the expansion head 4 in an integrally formed manner, and the diameter of the expansion head 4 is equal to the diameter of the rivet body 1, so that the production cost is low.
The implementation principle of the embodiment is as follows: firstly, when a rivet is installed, a worker combines a first installation plate 7 and a second installation plate 8, and enables through holes on the two installation plates to correspond to each other, then the worker passes through a rivet main body 1 through the through holes and draws out a mandrel 3 by using a tool, after the mandrel 3 is stressed, an expansion head 4 is retracted into the rivet main body 1, one end of the rivet main body 1 is expanded, the diameter of one end of the rivet main body 1 is larger than that of the through hole, then one end of the mandrel 3 is fixed by the expansion head 4, the other end is continuously stressed, so that the mandrel 3 is broken at the position of a guide groove 6 and is divided into two parts, and the diameter of one end of the rivet main body 1 and the width of a flange 2 are both larger than that of the through hole, so that the two installation plates are fixed together;
When the rivet needs to be disassembled, a worker screws a bolt 9 into the thread sleeve 5, then the worker respectively sleeves two wrenches on the flange 2 and the bolt 9, then the worker fixes the position of the flange 2 through one wrench to avoid rotation of the flange, meanwhile, the worker rotates the bolt 9 through the other wrench to enable the bolt 9 to enter the rivet main body 1, the bolt 9 enters the rivet main body 1 and then ejects the expansion head 4, so that the structural strength of one end of the rivet main body 1 is reduced and deformation is easy to generate, and then the worker pulls out the rivet main body 1 by force by using pliers or clamping the wrench in a gap between the bolt 9 and the flange 2.
