When the pin tail of the installation pin 200 is stressed, the pre-installation position A, the installation position B, and the disassembly position C can be respectively clamped in the first installation hole 103 to realize the disassembly and assembly of the injection molded part on the target part 300.

[0093] A clamping portion 102 that cooperates with the pre-installation position A, the installation position B, and the disassembly position C is provided at the tail inside the first installation hole 103. The radial dimension of the installation position is greater than the radial dimensions of the pre-installation position and the disassembly position.

[0094] A plurality of elastic posts 106 arranged around its axis are provided on the outer periphery of the installation post 101; a clamping portion 102 is provided at the lower part of the elastic post 106 close to the axis of the installation post 101;

[0095] The radial dimension of the installation pin 200 at the installation position B is greater than the radial dimensions of the installation pin 200 at the pre-installation position A and the disassembly position C; the clamping portion 102 can be sequentially clamped at the pre-installation position A, the installation position B, and the disassembly position C of the installation pin 200;

[0096] When the clamping portion 102 is clamped at the pre-installation position A and the disassembly position C of the installation pin 200, the installation post 101 and the target part 300 are movably connected, and the pre-installation and disassembly of the installation post 101 and the target part 300 can be realized; when the clamping portion 102 is clamped at the installation position B of the installation pin 200, the installation post 101 contacts the target part 300, and the fixation of the installation post 101 and the target part 300 can be realized.

[0097] The installation structure of an injection molded part of the present utility model includes an installation post 101, which realizes fewer parts of components, saves costs, and saves installation and disassembly man-hours; the installation of the present utility model is simple: the operator only needs to pick up the injection molded part and then place the injection molded part inside the target part 300, and press the installation pin 200, thus saving the steps of picking up tools and fasteners; the disassembly and maintenance of the present utility model are simple: the operator only needs to press the installation pin 200 to disassemble the injection molded part, without special tools, saving maintenance man-hours; the present utility model can be reused. When the installation pin 200 is in the disassembly position C, the injection molded part is taken out. At this time, the installation post 101 is in the initial state, and no scratches will be generated during the disassembly process. By directly pushing the installation pin 200 back to the pre-installation position A, reuse can be achieved.

[0098] The difference between this embodiment and the above embodiments is that:

[0099] A step portion 104 for accommodating the pin tail 202 is provided at the head of the installation post 101. The step portion 104 is used for limiting the installation pin 200 to prevent the installation pin 200 from detaching from the installation post 101.

[0100] At the connection between the installation post 101 and the injection molded part body 100, an installation surface 105 for contacting the target part 300 is provided. The installation surface 105 protrudes from the injection molded part body 100.

[0101] Specifically, a washer 400 for increasing friction is provided between the installation surface 105 and the target part 300. The washer is sleeved on the outer periphery of the installation post. One end of the washer 400 abuts against the installation surface 105, and the other end of the washer 400 is used to abut against the target part 300, making the connection between the injection molded part body 100 and the target part 300 more stable.
