DETAILED DESCRIPTION

[0020] The utility model will be further described below in connection with the drawings and embodiment.

[0021] Please refer to Figure 1 、 Figure 2 、 Figure 3 and wherein Figure 1 is a preferred embodiment of the detachable double locking pull rivet fastener provided by the utility model structural schematic diagram; Figure 2 is Figure 1 the structure schematic diagram of the pipe cap part front view cross-sectional view shown; Figure 3 is Figure 2 the structure enlarged schematic diagram of A area shown, detachable double locking pull rivet fastener, including: rivet 1, the outside of the rivet 1 is provided with pipe cap 2;

[0022] The outside of the pipe cap 2 is provided with adjusting part 21, the side opposite to the pipe cap 2 of adjusting part 21 is provided with internal and external thread 22, the pipe cap 2 is connected with adjusting part 21 through internal and external thread 22.

[0023] Through the setting of internal and external thread 22, adjusting part 21 can move up and down on the circumferential side of pipe cap 2, and because the bottom of adjusting part 21 is used to abut the top of two mutually fastening parts, the up and down movement of adjusting part 21 can adjust the fastening spacing between the two fastening parts, thereby improving the application range of rivet 1.

[0024] The inside of the rivet 1 and located inside the pipe cap 2 is provided with fracture groove 11, the inside of the rivet 1 and located below the fracture groove 11 is provided with positioning hole 12.

[0025] The inside of the pipe cap 2 is provided with sliding groove 23, the inside of sliding groove 23 is provided with sliding pin 24 that can slide left and right, the outer diameter of sliding pin 24 is same with the inner diameter of positioning hole 12.

[0026] When the rivet is pulled upward by rivet gun and broken at fracture groove 11, riveting part 14 is located at the bottom of the inside of pipe cap 2 at this time, and positioning hole 12 is located at the right side of sliding pin 24, sliding pin 24 will slide to the right side under the action of spring 25, and then insert into the inside of positioning hole 12, so that the bottom of rivet 1 will not rotate after being pulled off, thereby ensuring the fastening effect.

[0027] The inside of sliding groove 23 and located at the left end of sliding pin 24 is provided with spring 25, the left side of sliding pin 24 and located inside the pipe cap 2 is provided with disassembly rope 26, the top end of disassembly rope 26 and located at the top of pipe cap 2 is provided with pull ring 27.

[0028] When disassembling is needed, the disassembling rope 26 is pulled upward to move upward, and the sliding pin 24 is retracted, and the bottom riveting part 14 is knocked out by means of a tool.

[0029] The bottom of the adjusting part 21 and outside of the pipe cap 2 are provided with a gasket 28, and the bottom of the gasket 28 is provided with anti-skid teeth 29.

[0030] Through the setting of the anti-skid teeth 29, after the rivet 1 is riveted, the anti-skid teeth 29 are clamped on the top of the fastened object, and the adjusting part 21 is fixed on the top of the anti-skid teeth 29, so that the adjusting part 21 cannot be rotated and cannot be loosened.

[0031] The top of the side surface of the rivet 1 is provided with a clamping groove 13, and the bottom end of the rivet 1 is provided with a riveting part 14.

[0032] The working principle of the detachable double-locking pull rivet fastener is as follows:

[0033] Step 1: in use, according to the length of the fastened part, the height of the adjusting part 21 outside the pipe cap 2 is rotated, so that the length between the adjusting part 21 and the positioning hole 12 is slightly smaller than the length between the fastened parts, then the top of the rivet 1 is pulled out by the rivet gun, the riveting part 14 is clamped into the inside of the pipe cap 2, and the bottom of the pipe cap 2 is deformed to expand, so that the fastened part is fastened, and the broken slot 11 is broken, and the fastening is completed;

[0034] Step 2: in the process of completing the fastening, when the riveting part 14 continuously rises into the inside of the pipe cap 2, the positioning hole 12 gradually approaches the sliding pin 24 part, when completely coincides, the spring 25 pushes the sliding pin 24 to insert into the inside of the positioning hole 12, so that the rotation of the bottom riveting part 14 is avoided, and the fastening effect is guaranteed, and after the riveting is completed, the anti-skid teeth 29 are clamped on the top of the fastened object, and the adjusting part 21 is fixed on the top of the anti-skid teeth 29, so that the adjusting part 21 cannot be rotated and cannot be loosened.

[0035] Step 3: when disassembling, the disassembling rope 26 is pulled upward to move upward, and the sliding pin 24 is retracted, and the limiting effect of the riveting part 14 is removed, and the bottom riveting part 14 is knocked out by means of a tool, and then the pipe cap 2 and the adjusting part 21 are pulled up.

[0036] Compared with the related art, the detachable double-locking pull rivet fastener has the following beneficial effects:

[0037] When the riveting part 14 is continuously lifted into the inside of the pipe cap 2 during fastening, the positioning hole 12 gradually approaches the sliding pin 24 part, and when fully coincides, the spring 25 pushes the sliding pin 24 to insert into the inside of the positioning hole 12, thereby avoiding the rotation of the bottom riveting part 14, guaranteeing the fastening effect, and after the riveting is completed, the anti-skid tooth 29 is clamped on the top of the fastened object, and the adjusting part 21 is fixed on the top of the anti-skid tooth 29, thereby the adjusting part 21 cannot be rotated, and the loosening situation does not occur.

[0038] The above only describes the embodiments of the present application, and does not limit the patent range of the present application, and any equivalent structure or equivalent process transformation using the content of the present application specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection range of the present application.
