[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1 to 5 As shown, this utility model provides an impact-resistant structure for plastic parts, including a plastic part body 1, and buffer components 2 evenly distributed on the outer wall of the plastic part body 1.

[0031] The buffer assembly 2 includes a fixed cylinder 201, with a movable plate 202 inside the fixed cylinder 201. A buffer spring 203 is connected to the bottom of the movable plate 202, and a movable column 204 is fixedly connected to the top of the movable plate 202. A rubber buffer block 205 is connected to the top of the movable column 204 through the fixed cylinder 201. Multiple evenly distributed buffer assemblies 2 form a regional impact-resistant structure, improving the impact resistance of plastic parts. The buffer assembly 2 structure is detachable and replaceable, facilitating the use of the impact-resistant structure for plastic parts. The rubber buffer block 205 structure can deform to absorb the impact force, further improving the impact resistance of plastic parts. In conjunction with the buffer assembly 2, the impact resistance of plastic parts can be greatly improved.

[0032] Specifically, the inner wall of the plastic component body 1 is fixed with a grid structure 3. The grid structure 3 is composed of horizontal reinforcing ribs 301 and vertical reinforcing ribs 302 arranged perpendicularly to each other. The grid structure 3 greatly improves the overall impact resistance and can distribute the impact force on the horizontal reinforcing ribs 301 and vertical reinforcing ribs 302.

[0033] Furthermore, an installation groove 4 is provided on the plastic component body 1 at the position corresponding to the buffer assembly 2. The installation groove 4 is threadedly connected to the fixing cylinder 201 to facilitate the installation and removal of the buffer assembly 2.

[0034] Furthermore, the inner wall of the mounting groove 4 is engraved with internal threads, and the outer surface of the fixing cylinder 201 is engraved with external threads.

[0035] It is worth noting that a limiting ring 206 is fixed to the top of the outer wall of the fixed cylinder 201. The diameter of the limiting ring 206 is larger than the diameter of the mounting groove 4, which is used to limit the installation position of the fixed cylinder 201.

[0036] It is worth noting that a positioning through hole 207 is provided at the top of the fixed cylinder 201 at the position corresponding to the movable column 204. The movable column 204 passes through the positioning through hole 207 for the movement of the movable column 204.

[0037] It is worth mentioning that the rubber buffer block 205 is provided with a pressure chamber 2051, and the rubber buffer block 205 is provided with evenly distributed airflow holes 2052. The airflow holes 2052 are connected to the pressure chamber 2051. The cross-section of the airflow holes 2052 is conical. The pressure chamber 2051 and the airflow holes 2052 can increase the deformation range of the rubber buffer block 205. The conical airflow holes 2052 can reduce the exhaust rate and increase the intake efficiency.

[0038] Working principle and process: When the plastic parts are subjected to impact, the rubber buffer block 205 of the buffer assembly 2 drives the movable column 204 and the movable plate 202 to move, thereby compressing the buffer spring 203. The deformation of the buffer spring 203 is used to absorb the impact force and reduce the impact force acting on the plastic part body 1 until the rubber buffer block 205 contacts the plastic part body 1. Then the rubber buffer block 205 deforms, and the air in the air pressure chamber 2051 is discharged from the air flow hole 2052 to absorb the impact force and further improve the impact resistance of the plastic parts. In conjunction with the buffer assembly 2, the impact resistance of the plastic parts can be greatly improved. When the buffer assembly 2 needs to be replaced, simply rotate the fixed cylinder 201 to disengage it from the mounting groove 4. Both disassembly and assembly are relatively convenient. During installation, the limiting ring 206 on the fixed cylinder 201 can indicate the position of the fixed cylinder 201 to facilitate the installation of the buffer assembly 2. Multiple evenly distributed buffer assemblies 2 form a regional impact-resistant structure, which improves the impact resistance of the plastic parts.
