Description

Technical Field

[0001] This utility model relates to the field of sealing cap technology, and more specifically, to a four-channel sealing cap with reliable engagement. Background Technology

[0002] A four-channel sealing cap is a sealing device for multi-channel piping or cable systems. An existing sealing cap, with publication number CN208918774U, comprises a suction-side cover (22), a bolt insertion body (26), a suction-side holding body (24), and a body (21) integrally connecting the suction-side cover (22), the bolt insertion body (26), and the suction-side holding body (24). The bolt insertion body (26) protrudes from the surface (21A) of the body (21), and the suction-side cover (22) protrudes from the back (21B) of the body (21). The sealing cap (20) is formed of a material capable of elastic deformation. The suction-side holding body (24) has an annular portion (31) formed in a ring shape, and the opening formed by the annular portion (31) opens in a direction intersecting the insertion direction of the suction-side cover (22).

[0003] However, in this structure, because the smooth insert used in the cover plate relies solely on the linear contact between the cylindrical surface and the hole wall, the sealing pressure distribution is uneven, which can easily produce tiny gaps, resulting in a significant reduction in sealing performance. Utility Model Content

[0004] The main purpose of this utility model is to provide a reliable four-channel sealing cover, which can effectively solve the problem in the prior art where the smooth insert of the cover plate relies solely on the linear contact between the cylindrical surface and the hole wall, resulting in uneven sealing pressure distribution, easy generation of micro gaps, and a significant reduction in sealing performance.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A reliable four-channel sealing cap includes a four-channel cover plate, on the upper surface of which a plurality of rubber rings are fixedly installed, and a plurality of sealing components are fitted on one side of the outer wall of each rubber ring.

[0007] Preferably, the sealing assembly includes a plurality of rubber rings, each of which is fitted onto the outer wall of a corresponding rubber ring.

[0008] Preferably, the outer wall surface of the rubber ring is set as an arc surface.

[0009] Preferably, each of the rubber rings is fitted with an annular sealing ring on its outer wall.

[0010] Preferably, each of the annular sealing rings has a cavity in its inner wall.

[0011] Preferably, each cavity is provided with an elastic element.

[0012] Preferably, the elastic element is a ring spring.

[0013] Compared with the prior art, the present invention has the following beneficial effects: (1) After the rubber ring is inserted into the hole, by setting the rubber ring, the sealing pressure is evenly distributed under the action of the rubber ring and the hole wall, avoiding the generation of small gaps, greatly improving the sealing performance, preventing external dust from entering, and thus greatly enhancing the sealing performance.

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0021] like Figures 1-6 As shown, a reliable four-channel sealing cover includes a four-channel cover plate 1, with several rubber rings 2 fixedly installed through the upper surface of the four-channel cover plate 1, and several sealing components 3 sleeved on one side of the outer wall of each rubber ring 2.

[0022] The sealing assembly 3 includes several rubber rings 301, each rubber ring 301 being sleeved on the outer wall of the corresponding rubber ring 2.

[0023] After the rubber ring 2 is inserted into the hole, the rubber ring 301 is set so that the sealing pressure is evenly distributed under the action of the rubber ring 2 and the hole wall, avoiding the generation of tiny gaps, greatly improving the sealing performance, and preventing external dust from entering, which would greatly reduce the sealing performance.

[0024] In another embodiment of this utility model, the outer wall surface of the rubber ring 2 is set as an arc surface.

[0025] By setting the outer wall of the rubber ring 2 to an arc surface, the outer wall of the surface rubber ring 2 is locked to the end of the hole.

[0026] In another embodiment of this utility model, each rubber ring 2 is fitted with an annular sealing ring 4 on its outer wall.

[0027] Each annular sealing ring 4 has a cavity 5 on its inner wall.

[0028] Elastic elements 6 are provided inside each cavity 5.

[0029] The elastic element 6 is a ring spring.

[0030] Under the elastic force of the elastic element 6, the outer wall of the annular sealing ring 4 fits tightly against the inner wall of the hole, further enhancing the sealing performance.

[0031] The working principle of this reliable four-channel sealing cap:

[0032] In use, after the rubber ring 2 is inserted into the hole, the rubber ring 301 is set so that the sealing pressure is evenly distributed under the action of the rubber ring 2 and the hole wall, avoiding the generation of tiny gaps, greatly improving the sealing performance, preventing external dust from entering, and thus greatly enhancing the sealing performance.

[0033] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
