Description

Technical Field

[0001] This utility model belongs to the field of plastic product manufacturing technology, and in particular relates to a plastic part. Background Technology

[0002] After plastic products are molded, a dustproof cloth is typically attached to their surface to prevent the intrusion of external dust, particles, and chemicals, thereby protecting the plastic products from contamination and extending their lifespan. However, the traditional method of attaching the dustproof cloth to the surface of plastic products requires manually straightening the cloth and then gluing it to the surface. This method, due to the use of glue, can cause some environmental pollution. Furthermore, once the dustproof cloth is glued to the plastic product, if replacement is needed, both the dustproof cloth and the plastic product must be discarded, undoubtedly increasing production costs.

[0028] Please see Figures 1 to 4 This utility model discloses a plastic part, which includes:

[0029] The main body 1 is provided with a plurality of limiting grooves 11 and / or limiting protrusions 12;

[0030] The buckle part 2 is provided with a plurality of buckle protrusions 21 and / or buckle grooves 22. Each buckle protrusion 21 is engaged with the corresponding limiting groove 11, and each buckle groove 22 is engaged with the corresponding limiting protrusion 12.

[0031] Dustproof cloth 3 is integrally attached to the side of the buckle part 2 that is opposite to the main body part 1.

[0032] In the above-described configuration, the plastic part includes a main body 1, a snap-fit ​​part 2, and a dustproof cloth 3. The main body 1 has multiple limiting grooves 11 and / or limiting protrusions 12, and the snap-fit ​​part 2 has multiple snap-fit ​​protrusions 21 and / or snap-fit ​​grooves 22. Each snap-fit ​​protrusion 21 engages with a corresponding limiting groove 11, and each snap-fit ​​groove 22 engages with a corresponding limiting protrusion 12. This allows the snap-fit ​​part 2 to engage with the main body 1. The dustproof cloth 3 is directly and integrally attached to the side of the snap-fit ​​part 2 facing away from the main body 1 to prevent external dust, particles, and chemicals from penetrating the plastic part. Therefore, when the dustproof cloth 3 needs to be replaced, only the snap-fit ​​part 2 and the dustproof cloth 3 need to be removed from the main body 1 simultaneously for replacement, eliminating the need to scrap the entire plastic part and effectively saving on subsequent disassembly and maintenance costs.

[0033] Please see Figures 1 to 4 Specifically, in this embodiment, the main body 1 is a hollow cylindrical shape with openings on its sides, and its bottom ends have openings for connecting / inserting other components. The sides of the main body are also provided with multiple limiting grooves 11 and limiting protrusions 12. More specifically, the limiting grooves 11 and limiting protrusions 12 are arranged on the circumferential edges of the main body 1. Further, the limiting grooves 11 are distributed in a dotted pattern on the upper and lower, and left and right connecting edges of the main body 1, and are elongated along the upper and lower edges of the main body 1. The limiting protrusions 12 are elongated and located on the left and right edges of the side openings of the main body 1. Correspondingly, the latching part 2 includes a corresponding number of dotted latching protrusions 21, elongated latching protrusions 21, and elongated latching grooves 22, thereby enabling the latching part 2 to be fastened to the main body 1. Of course, in other embodiments, the main body 1 may also be in other shapes, and it may only be provided with a limiting groove 11 or a limiting protrusion 12. Correspondingly, the buckle part 2 may only be provided with a buckle protrusion 21 or a buckle groove 22.

[0034] Specifically, in this embodiment, the depth of the limiting groove 11 and the height of the snap-fit ​​protrusion 21 are equal to the thickness of the main body 1, and the height of the limiting protrusion 12 and the depth of the snap-fit ​​groove 22 are equal to the thickness of the main body 1, thereby enabling the main body 1 and the snap-fit ​​part 2 to be tightly and stably connected. More specifically, both the limiting groove 11 and the snap-fit ​​groove 22 are through grooves, so that after the main body 1 and the snap-fit ​​part 2 are connected, the outer surfaces of the main body 1 and the snap-fit ​​part 2 are on the same plane without any additional protrusions, ensuring that the external shape of the plastic part does not change.

[0035] Specifically, in this embodiment, the four dot-shaped latching protrusions 21 and the four strip-shaped latching protrusions 21 are arranged in two groups, each surrounding one of the two strip-shaped latching grooves 22. The four dot-shaped latching protrusions 21 and the two strip-shaped latching protrusions 21 are independent. Naturally, the latching part 2 is generally rectangular. Of course, in other embodiments, the number and shape of the latching protrusions 21 and the latching grooves 22 can be set according to actual needs.

[0036] Specifically, in this embodiment, the buckle part 2 is injection molded onto the edge of one side of the dustproof cloth 3. In other words, the process of molding the buckle part 2 using a mold is as follows: before injecting liquid plastic into the mold cavity used to mold the buckle part 2, the dustproof cloth 3 is first placed into the mold cavity, and then liquid plastic is injected into the mold cavity. This allows the liquid plastic to cool and adhere directly to the dustproof cloth 3 to form the buckle part 2. Thus, although the buckle part 2 and the dustproof cloth 3 are integrally bonded, no glue is needed, avoiding environmental pollution caused by using glue.

[0037] Specifically, in this embodiment, the side of the main body 1 is provided with a plurality of hollow holes 13. When the buckle part 2 is fastened and connected to the main body 1, the dustproof cloth 3 will cover the hollow holes 13 to prevent external dust, particles and chemicals from entering the plastic part from the hollow holes 13.

[0038] Specifically, in this embodiment, the dustproof cloth 3 is made of nylon cloth, which has good extensibility and breathability. While effectively preventing dust from entering the plastic part, it does not affect the function of the perforated hole 13 (such as allowing airflow and heat dissipation inside the plastic part).

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any changes, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
