Description

Technical Field

[0001] The present invention belongs to the field of spray painting protection components, and particularly relates to a protective cover for a spray painting fixing component. Background Art

[0002] The flared pipe connector includes a circular pipe section and a flared section that are connected to each other. Generally, only the circular pipe section is spray painted. At present, for the spray painting protection of flared pipe connectors in China, components such as flat nozzles, outer nuts, and plugs are mainly used to limit the flared section of the flared pipe connector and ensure that its circular pipe section can extend to the outside to form a spray painting fixing component to assist in spray painting. At present, although the spray painting fixing component can limit the flared section of the flared pipe connector, the spray painting fixing component itself will displace during the spray painting process. At the same time, the spray painting fixing component is also exposed during the spray painting process and is not protected. After a long time, it will cause certain damage to the spray painting fixing component, ultimately affecting the spray painting effect. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a protective cover for a spray painting fixing component to solve the above problems and achieve the protection of the spray painting fixing component during the spray painting process in view of the deficiencies of the above-mentioned prior art.

[0004] The technical solution adopted by the present invention is: a protective cover for a spray painting fixing component, including a cover body. One end of the cover body is provided with a plug cover component that is threadedly connected to its inner wall and allows the spray painting fixing component to pass through. The other end of the cover body is provided with an end cover that is hermetically connected to its interior. One end of the cover body near the spray painting fixing component is provided with a spring plug that contacts and presses the spray painting fixing component. One end of the inner side of the cover body near the end cover is provided with a hole retaining ring. A spring washer is arranged inside the hole retaining ring. A compression spring is arranged between the spring washer and the spring plug.

[0005] In one embodiment, the cover body includes a housing body. One end face of the housing body near the end cover is provided with several connecting threaded holes. An installation threaded hole and an installation through hole are opened inside the housing body. The installation threaded hole is far from the end cover and is communicated with the installation through hole. The diameter of the installation threaded hole is larger than that of the installation through hole. A retaining ring installation groove is arranged on the inner side wall of one end of the installation through hole near the end cover.

[0006] In one embodiment, an inner guiding groove is arranged at one end of the installation threaded hole far from the installation through hole.

[0007] In one embodiment, the outer surface of the plug cover component is provided with an external thread that matches the installation threaded hole, and the external thread of the plug cover component is threadedly connected to the installation threaded hole.

[0008] In one embodiment, the plugging cover assembly includes two symmetrically arranged semi-circular plugging covers. On the opposite faces of the two semi-circular plugging covers, a first semi-ring, a second semi-ring, and a third semi-ring which are sequentially connected and have sequentially decreasing radii are symmetrically arranged from the end close to the shield body to the end far from the shield body. When the two semi-circular plugging covers are assembled, a first limiting through-hole, a second limiting through-hole, and a third limiting through-hole are respectively formed between the first semi-ring, the second semi-ring, and the third semi-ring of the two semi-circular plugging covers.

[0009] In one embodiment, the end cover includes a cover body. A threaded through-hole matching the connecting threaded hole is formed on one end face of the cover body, and the connecting threaded hole and the threaded through-hole are connected by a screw. A painting boss is provided at the end of the cover body far from the shield body, and a kidney-shaped hole is formed on the painting boss.

[0010] In one embodiment, the spring plug includes a first plug body in contact with the painting fixing assembly and a second plug body connected to the first plug body. A plug spring slot is provided at one end of the second plug body close to the first plug body.

[0011] In one embodiment, the spring washer includes a first washer body disposed between the end cover and the hole retaining ring, and a second washer body passing through the hole retaining ring and extending to the outside of one end of the hole retaining ring close to the spring plug. A limiting protrusion is provided at one end of the second washer body far from the first washer body. A washer spring slot is formed between one end of the limiting protrusion close to the first washer body, the outside of the second washer body, and one end of the first washer body close to the second washer body.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The shield body and the end cover are connected by screws to form an unclosed barrel, which can prevent foreign matters such as dust from entering from the outside.

[0014] 2. The setting of the plugging cover assembly can ensure the passage of the painting fixing assembly and also limit it, which can fully ensure the painting effect.

[0015] 3. The assembly composed of the spring plug, the spring washer, and the compression spring limits the painting fixing assembly, and the compression spring continuously provides elastic force, so that the entire assembly and the painting fixing assembly to be protected will not have axial displacement after assembly.

[0016] 4. The plug spring slot and the washer spring slot are respectively provided on the spring plug and the spring washer, which can make the connection of the compression spring more stable.

[0017] 5. The plug cover assembly is designed to be in two halves, and inside it are provided with a first limiting through hole, a second limiting through hole, and a third limiting through hole. After assembly, the gap between the plug cover assembly and the paint spraying fixing assembly is very small, which can prevent paint from entering the interior during paint spraying.

[0018] 6. The end cover is provided with a paint spraying boss, and there is an oblong hole on the paint spraying boss, which can be used to hang the part during paint spraying, facilitating the paint spraying operation. Brief Description of the Drawings
