Description

Technical Field

[0001] The utility model relates to the technical field of mechanical manufacturing, in particular to a water-leakage-proof sealing screw structure. Background Art

[0002] Screws play a very important role in mechanical manufacturing. They are tools that fasten objects together. Screws usually consist of a threaded part and a head. By rotating the screw and applying a certain force, the screw can be embedded into another object to connect, fix or adjust it.

[0003] The existing patent application number is 201922101493.9, and the Chinese patent announcement number is CN211474636U. It is a screw structure for liner installation that is leak-proof and loose-proof, including a hexagonal countersunk bolt, an inner liner, a container and a tapered nut. The hexagonal countersunk bolt and the tapered nut are locked to tightly fit the inner liner to the inner wall of the container. The tapered surface of the tapered nut has an interference fit with the through hole on the container wall. During the assembly process, the tapered surface squeezes the contact surface between the tapered surface and the through hole to be flat and smooth, reducing gaps and preventing water leakage. The tapered nut can also be automatically guided to achieve precise positioning and reduce manufacturing errors.

[0004] In combination with the above solution, there are the following problems: the design of the existing anti-leakage screw is relatively simple, and usually only relies on a single structure or material to achieve the anti-leakage function. It is difficult to achieve multiple anti-leakage effects, thus affecting the overall anti-leakage performance, and the sealing performance is generally poor, affecting the sealing effect.

[0005] Therefore, based on the above technical problems, it is necessary for technicians in this field to develop a water-proof sealing screw structure. Utility Model Content

[0006] The utility model aims to provide a water-leakage-proof sealing screw structure to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A technical solution for a water-leakage-proof sealing screw structure comprises a partition plate, a threaded hole is arranged on the partition plate, a gasket is arranged outside the threaded hole, and a sealing hole is arranged on the gasket, a screw is arranged in the threaded hole, and a gasket and a sealing ring are arranged on the outer sleeve of the screw.

[0009] As a preferred technical solution, the inner diameter of the sealing hole is larger than the inner diameter of the threaded hole, the inner diameter of the sealing ring is larger than the inner diameter of the threaded hole and smaller than the inner diameter of the sealing hole, and the sealing ring is located in the sealing hole.

[0010] As a preferred technical solution, the bottom surface of the sealing ring is provided with a triangular groove in a circumferential shape.

[0011] As a preferred technical solution, a boss is provided on the bottom surface of the washer, and the boss is truncated in a cone shape. Both the boss and the washer are provided with movable holes, and are sleeved outside the screw.

[0012] As a preferred technical solution, the boss is fixedly connected to the gasket.

[0013] As a preferred technical solution, the outer wall of the sealing ring is in close contact with the inner wall of the sealing hole.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model is a water-leakage-proof sealing screw structure, in which the sealing ring and the gasket are arranged to form a double sealing effect, thereby enhancing the water-leakage-proof performance of the screw. At the same time, the triangular groove design of the sealing ring can increase the sealing effect, so that when the screw is tightened, it can fit more closely on the object to be fixed. The convex seat design of the gasket can increase the stability of the screw, making the screw less likely to loosen. At the same time, the convex seat can also be used to further squeeze the rubber ring to improve the sealing effect between the interfaces. The screw structure can effectively prevent water from leaking from the connection, ensuring the normal operation and service life of the equipment. At the same time, the screw structure has a simple design, is easy to manufacture and use, can reduce production costs and maintenance costs, and improve economic benefits. Through multiple sealing designs and optimized structures, the water-leakage-proof performance and stability of the screw are improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0021] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model provides a technical solution for a water-leakage-proof sealing screw structure: it includes a partition 1, a threaded hole 11 is provided on the partition 1, a gasket 2 is provided outside the threaded hole 11, and a sealing hole 21 is provided on the gasket 2, a screw 3 is provided in the threaded hole 11, a gasket 4 and a sealing ring 5 are provided on the outer sleeve of the screw 3, and a triangular groove 51 is provided in a circular shape on the bottom surface of the sealing ring 5, the inner diameter of the sealing hole 21 is larger than the inner diameter of the threaded hole 11, the inner diameter of the sealing ring 5 is larger than the inner diameter of the threaded hole 11 and smaller than the inner diameter of the sealing hole 21, the sealing ring 5 is located in the sealing hole 21, the outer wall of the sealing ring 5 is tightly attached to the inner hole wall of the sealing hole 21, a convex seat 41 is provided on the bottom surface of the gasket 4, the convex seat 41 is fixedly connected to the gasket 4, the convex seat 41 is truncated, and the convex seat 41 and the gasket 4 are both provided with movable holes through them, and are sleeved outside the screw 3.

[0022] According to the above solution, in this embodiment, when in use, the screw 3 is screwed into the threaded hole 11. During the screwing process of the screw 3, the sealing ring 5 will be compressed and closely fit in the sealing hole 21 of the gasket 2, forming a first layer of sealing effect. At the same time, the convex seat 41 of the gasket 4 will also squeeze and contact the sealing ring 5, increasing the stability of the screw.

[0023] When the screw 3 is tightened in place, the gasket 2 and the sealing ring 5 will form a complete sealing structure to prevent water from leaking from the connection. The triangular groove 51 design of the sealing ring 5 can increase the sealing effect, so that the screw 3 fits more tightly on the object to be fixed.

[0024] In addition, the convex seat 41 of the gasket 4 can also be used to further squeeze the rubber ring to improve the sealing effect between the interfaces. When the screw 3 is tightened, the convex seat 41 will squeeze the rubber ring and deform it, thereby filling the tiny gap between the interfaces and further improving the sealing performance.

[0025] The water-proof sealing screw structure effectively improves the water-proof performance and stability of the screw through multiple sealing designs and optimized structures. It has a simple design, is easy to manufacture and use, can reduce production costs and maintenance costs, and improve economic benefits. At the same time, the screw structure also has good versatility and adaptability, and can be widely used in various equipment and scenarios that require waterproof sealing.
