Description

Technical Field

[0001] This utility model relates to the field of housing sealing structure for anti-corrosion paint production, and more specifically, to a housing sealing structure for anti-corrosion paint production. Background Technology

[0002] Anti-corrosion paint generally refers to coatings used in harsh corrosive environments to delay and reduce corrosion of metal structures. It includes primers and topcoats. Simply put, anti-corrosion paint is a coating with a longer service life and the ability to withstand more demanding environments. Paint buckets are sealed containers used in industrial production to hold liquid paint. They are mainly made of metal (such as galvanized iron) and plastic. Metal buckets are coated with anti-rust paint, while plastic buckets are corrosion-resistant and impact-resistant. Most existing anti-corrosion paint cans have snap-fit ​​cap structures. For example, the present invention disclosed in authorization announcement number CN220054769U discloses a paint can with an improved structure, including a paint can body, a handle and a top cover. The handle is rotatably connected to the upper sides of both sides of the paint can body. The top cover is installed on the top of the paint can body. An auxiliary opening structure is provided inside the top of the top cover. A discharge structure is provided at the bottom of one side of the paint can body. The discharge port is opened at the bottom of one side of the paint can body. A stacking structure is fixedly connected to the bottom of the paint can body. This invention features a discharge structure. After most of the paint inside the paint bucket has been poured out, the bucket can be placed normally. Then, the protective film is removed, and the rubber stopper is pulled out from the discharge port by pulling the second buckle. As the paint bucket sits still, any remaining paint on the inner wall will gradually drip downwards and flow out through the discharge port, thus reducing the amount of paint residue on the inner wall and achieving convenient discharge of residual paint. It can be used by simply prying open the snap-fit ​​cap. However, the snap-fit ​​cap has drawbacks: it requires tools to pry open, making it inconvenient to use. If it is deformed by pressure after being inserted, the snap-fit ​​cap will deform, resulting in a poor seal and easy ejection. Furthermore, it requires tools to open, making it inconvenient to use. Utility Model Content

[0003] To address the problems existing in the prior art, the purpose of this utility model is to provide a sealing structure for a shell used in the production of anti-corrosion paint. The shell body of the paint cylinder is equipped with an inner ring protrusion structure, and its threaded outer cover body is fixed by threaded connection. The embedded installation is firm, which not only blocks the seal and improves the sealing performance, but also ensures that the threaded connection is firmly fixed after installation, making it difficult to be pushed out and not easily affected by deformation. It also has a built-in flip-up and disassembly handle structure, which is convenient to open and easy to use.

[0004] To solve the above problems, the present invention adopts the following technical solution.

[0005] A sealing structure for a paint canister in production includes a paint canister body. An inner ring protrusion is provided on the upper inner surface of the paint canister body. A threaded outer cover body is threadedly connected to the inner surface of the inner ring protrusion. A strip-shaped groove is provided on the upper surface of the threaded outer cover body. A flip-up / removal handle is hinged to the inner surface of the strip-shaped groove. A locking positioning claw is fixed to the outer surface of the paint canister body. The flip-up / removal handle is locked onto the inner surface of the locking positioning claw. A first rubber sealing ring is provided on the inner surface of the recess of the inner ring protrusion, and a second rubber sealing ring is provided on the protruding surface of the inner ring protrusion. The inner ring protrusion structure inside the paint canister body, along with the threaded outer cover body fixed by the threaded connection, ensures a secure and embedded installation. This design improves sealing performance by preventing the seal from being pushed out or deformed after the threaded connection is established. The built-in flip-up / removal handle structure facilitates opening and use.

[0006] Furthermore, the inner end surface of the inner ring protrusion is provided with a supporting protrusion ring, and the upper surface of the supporting protrusion ring is slidably engaged with an inner cover plate.

[0007] Furthermore, an operating pull head is fixedly connected to the upper surface of the snap-fit ​​inner cover plate, and the operating pull heads are distributed on one side of the upper surface of the snap-fit ​​inner cover plate.

[0008] Furthermore, a brush is placed on the upper surface of the snap-fit ​​inner cover, and the lower surface of the cover is pressed against the surface of the brush.

[0009] Furthermore, an inner ring groove is provided in the recessed part of the inner ring protrusion, and the first rubber sealing ring is engaged with the inner surface of the inner ring groove.

[0010] Furthermore, the protrusion of the inner ring is provided with an inner ring groove, and the second rubber sealing ring is engaged with the inner surface of the inner ring groove.

[0011] Furthermore, the flip-up handle adopts a folded rib structure, and the upper surface of the flip-up handle is provided with a folded hinge joint. The folded hinge joint of the flip-up handle is hinged to the inner surface of the strip groove of the threaded outer cover body.

[0012] Compared with existing technologies, the advantages of this utility model are: (1) The inner ring protrusion structure is set inside the body of the paint can shell, and its threaded outer cover body is fixed by threaded connection. It is firmly installed in the inner ring, which blocks the seal and improves the sealing performance. At the same time, the threaded connection is firmly fixed and not easy to be pushed out. It is not easy to be affected by deformation and seal. It has a built-in flip-up and disassembly handle structure, which is convenient to open and easy to use. Attached Figure Description
