Detailed Description
The invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 to 5, the pin body is provided with a head portion 1, a first positioning portion 2, a second positioning portion 3, a fracture portion 4 and a handle portion 5 from top to bottom, the first positioning portion 2 and the second positioning portion 3 are both cylindrical structures, the outer side of the upper portion of the fracture portion 4 is an arc surface, the structure of the lower portion of the fracture portion 4 is a cylindrical structure, the upper structure of the handle portion 5 is a conical structure, the lower portion of the handle portion 5 is a flat structure, and a circular hole is formed in the center of the lower portion of the handle portion 5.
The head 1 is provided with a Z-shaped groove 8.
The outer side of the pin body is sequentially sleeved with a first part 9 and a second part 10 from top to bottom, a pin hole 6 is formed in one side of the first part 9, and the pin hole 6 is clamped with the first positioning part 2; one side of the second part 10 is provided with an opening hole 7, the opening hole 7 is clamped with the second positioning part 3, and the opening hole 7, the bolt hole 6 and the pin body are arranged concentrically.
The diameter of the first positioning part 2 is 4.9 mm; the diameter of the pin hole 6 is 5 mm.
The diameter of the second positioning part 3 is 3.8 mm; the diameter of the opening hole 7 was 4 mm.
The pin body is made of ABS or PC.
The diameter of the lower part of the breaking part 4 is 1.8 mm.
The diameter of the upper portion of the handle portion 5 is 4.6mm, and the diameter of the lower portion of the handle portion 5 is 3.8 mm.
The 5 lower parts of the pin body handle parts are of flat structures, and the flat structures are more favorable for pushing the pin body handle parts 5 and facilitating product disassembly. The round hole at the lower end of the handle part 5 can be added with a steel wire, so that the whole structure can be conveniently sealed by lead.
The utility model discloses during the use, can fix first part 9, second part 10 in the first location portion 2 of pin body, second location portion 3 department respectively. When disassembly is required, as shown in fig. 2, a force in the N direction is applied to the handle portion 5, and the pin body is broken at the breaking portion 4, so as to disassemble the first component 9 and the second component 10, which includes the following specific operation steps:
s1, the first part 9 is stacked with the second part 10 to ensure that the pin hole 6 of the first part 9 is concentrically aligned with the opening hole 7 of the second part 10.
And S2, the pin body passes through the bolt hole 6 on the first part 9, and the bolt hole 6 is ensured to be clamped with the first positioning part 2 of the pin body.
S3, the pin body is pressed down forcibly, and the pin body passes through the open hole 7 of the second part 10. Because the structure of the upper end of the pin body handle part 5 is a conical structure, the diameter of the upper end of the pin body handle part is 4.6mm, and the diameter of the lower end of the pin body handle part is 3.8mm, under the condition that the pin body is pressed down forcibly, the lower end of the pin body handle part 5 can smoothly enter the open hole 7 and can extrude the open hole 7 with the diameter of 4mm outwards, at the moment, the open hole 7 can deform under pressure, so that the aperture of the open hole is enlarged, the pin body handle part 5 can penetrate through the open hole 7 until the open hole 7 is clamped with the second positioning part 3 of the pin body, at the moment, the deformation generated by the open hole disappears, the pin body recovers the original shape, and the first part 9.
S4, when it is desired to detach the first and second elements 9, 10, the handle portion 5 of the pin body can be pushed by a screwdriver or a stick-like tool in the direction of N as shown in fig. 2. Because the material of the pin body is ABS or PC, and the diameter of the lower part of the breaking part is only 1.8mm, the pin body breaking part 4 can not bear large force, and finally the pin body breaking part 4 is broken, and the first part and the second part 10 can be detached.
And, because the upper portion of pin body handle portion 5 is the toper structure, and its upper end is the terminal surface that the diameter is 4.6mm, can produce the structure of detaining with the terminal surface full laminating of second part 10. Causing the pin body to be unable to be pushed out of the reverse side.
In order to ensure that the bolt hole 6 is clamped with the first positioning part 2 of the pin body, the open hole 7 is clamped with the second positioning part 3 of the pin body, the thickness of the first positioning part 2 is not more than the thickness of the position of the bolt hole 6 of the first part 9, the thickness of the second positioning part 3 and the breaking part 4 is not less than the thickness of the position of the open hole 7 of the second part 10, and the thickness of the first positioning part 2, the thickness of the second positioning part 3 and the breaking part 4 is not less than the thickness of the position of the bolt hole 6 of the first part 9 and the thickness of the position of the open hole 7 of the second part 10.
Further, the sum of the thicknesses of the first positioning portion 2, the second positioning portion 3 and the break-off portion 4 is 0.05mm greater than the sum of the thicknesses at the positions of the pin holes 6 of the first part 9 and the open holes 7 of the second part 10.
The utility model has simple structure, convenient installation, high installation efficiency, lower cost, safety and reliability; the product has higher identification degree after being disassembled, thereby effectively preventing the product from being disassembled; the product can be disassembled by destroying the pin under the condition of not destroying the appearance of the product, the damage to the pin can not cause the surface damage of the product, and the product is lead-sealed again.
