[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1-9, the present invention provides a technical solution: a wear-resistant hardware plastic car key protective cover that is easy to disassemble, including a first outer shell 1, a first groove 2, a second outer shell 3, a second groove 4, a button 5, a control panel 6, a car logo groove 7, a waterproof ring 8, a key 9, a limit joint 10, a third groove 11, a connecting rod 12, a spring 13, a first limit slot 14, a second limit slot 15, a key slot 16 and a waterproof ring connection slot 17. First grooves 2 are reserved on both the upper and lower sides of the front end of the first outer shell 1. The second outer shell 3 is located on the right side of the first outer shell 1, and a second groove 4 is reserved on the front end face of the second outer shell 3. The materials of the first outer shell 1 and the second outer shell 3 are both acetal, and the first outer shell 1 and the second outer shell 3 form a disassembly structure. Acetal is a highly wear-resistant plastic, which can increase the wear resistance of this plastic car key protective cover. Compared with the traditional plastic car key protective cover, this product is more difficult to be scratched. A button 5 is installed inside the second groove 4. The button 5 and the connecting rod 12 form an integral structure, and the whole of the button 5 and the connecting rod 12 forms a telescopic structure with the second outer shell 3. The height of the button 5 is less than the height of the second groove 4, which can reduce the probability of the button 5 being rubbed and protect the button 5. At the same time, by pressing the button 5, it can play a role in opening and closing the first outer shell 1 and the second outer shell 3. The control panel 6 is installed on the rear end face of the first outer shell 1. A car logo groove 7 is reserved on the rear end face of the second outer shell 3. A waterproof ring 8 is connected to the periphery of the right end face of the first outer shell 1. The shape of the waterproof ring 8 is annular, and the shape and size of the waterproof ring 8 are the same as those of the waterproof ring connection slot 17. When the first outer shell 1 and the second outer shell 3 are combined, the waterproof ring 8 will be squeezed into the waterproof ring connection slot 17, thereby effectively sealing the gap between the first outer shell 1 and the second outer shell 3 and playing a waterproof effect. The key 9 is installed at the middle position of the left end of the second outer shell 3, and limit joints 10 are provided at both the upper and lower ends of the key 9. There are two limit joints 10, and a triangular protrusion structure is provided at the upper left end of the limit joint 10. And the limit joint 10 and the connecting rod 12 form an integral structure. By moving the connecting rod 12 up and down, the limit joint 10 can be driven to move up and down in the first limit slot 14, which is convenient for subsequent installation and disassembly of the limit joint 10. The key 9 forms a disassembly structure with the first outer shell 1 through the key slot 16. A third groove 11 is reserved at the left end inside the second outer shell 3. The bottom of the button 5 is located in the third groove 11, and the lower end of the button 5 is connected to the connecting rod 12. Limit joints 10 are fixedly connected to both the upper and lower ends of the connecting rod 12, and springs 13 are evenly installed at the bottom of the lowermost limit joint 10. The limit joint 10 passes through the second outer shell 3 through the first limit slot 14. A key slot 16 is reserved at the middle position of the right end face of the first outer shell 1, and second limit slots 15 are reserved on both the upper and lower sides of the key slot 16. The depth of the second limit slot 15 is the same as the length of the limit joint 10 protruding from the left end of the second outer shell 3, and the shape of the upper end inside the second limit slot 15 is the same as the shape of the limit joint 10.Moreover, the limit joint 10 forms a detachable structure with the first housing 1 through the second limit groove 15. When the limit joint 10 enters the second limit groove 15, it can catch the second limit groove 15, thereby fixing the first housing 1 and the second housing 3. A waterproof ring joint groove 17 is reserved around the left end face of the second housing 3.

[0037] The present invention also provides a manufacturing process for a wear-resistant and detachable hardware plastic car key protective cover, and its steps include:

[0038] S1: Select the manufacturing materials and clean them;

[0039] S2: Dry the cleaned materials;

[0040] S3: Add the materials into the feed inlet of the plastic extruder and heat and melt the plastic;

[0041] S4: Push the melted materials through the machine head into the mold by the feeding screw;

[0042] S5: Cool and form the products in the mold;

[0043] S6: Demold and take out the formed products from the mold cavity;

[0044] S7: Polish the finished products to remove the scraps;

[0045] S8: Perform final finishing on the products to make them formed.

[0046] After the process of step S2, the materials need to be filtered through a magnetic rod and a filter screen to filter out metal particles and impurities in the materials, preventing them from entering the subsequent processing and affecting the quality of the products.

[0047] Working principle: When manufacturing the wear-resistant and detachable hardware plastic car key protective cover, appropriate-sized acetal plastic particles can be selected first, cleaned, dried, and then the metal and impurities in the particles are filtered by a magnetic roller and a filter screen to ensure the qualification rate of subsequent products. Then the materials are put into a plastic extruder. After being melted and pushed by a screw, they are extruded into a mold through the machine head. After sufficient cooling, the products are demolded. Then the products are polished and cut to remove the excess scraps. Finally, the final finishing is carried out, and components such as keys are installed on the housing.

[0048] When using this easily detachable wear-resistant hardware and plastic car key protector, the button 5 in the second groove 4 can be pressed. At this time, the button 5 will move downward in the third groove 11, thereby driving the connecting rod 12 to move downward. At this time, the right end of the limit joint 10 moves downward in the first limit groove 14, and the left end of the limit joint 10 moves up and down in the second limit groove 15, so that the limit joint 10 can be separated from the second limit groove 15, thereby separating the first housing 1 and the second housing 3, and allowing the key 9 to be removed from the key slot 16, so as to use the key to start the car. When it is not needed, the first housing 1 and the second housing 3 can be docked again. When the key 9 enters the key slot 16, the limit joint 10 can enter the second limit groove 15, so that the second limit groove 15 can hold the limit joint 10, thereby quickly fixing the limit joint 10. The whole disassembly and installation process is convenient. The setting of the waterproof ring 8 and the waterproof ring groove 17 can make the waterproof ring 8 snap into the waterproof ring groove 17 after the first housing 1 and the second housing 3 are installed, thereby preventing water from entering the product and achieving the waterproof effect.

[0049] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
