Description

Technical Field

[0001] This utility model relates to the field of gasket technology, specifically to a gasket with an anti-detachment structure. Background Technology

[0002] A gasket is a mechanical sealing element placed between two or more mating surfaces to prevent fluid or gas leakage. It can fill irregularities on machined surfaces, prevent loosening by increasing the contact area and reducing pressure, and protect parts and screws. In engines, gaskets are used to seal components such as cylinder heads and oil pans; in piping systems, they are used to seal connections such as pipes and valves.

[0003] In the prior art, gaskets are usually fitted onto the outside of cylindrical workpieces. Often, due to insufficient roughness of the contact surfaces between the two or improper use of lubricant, insufficient friction may occur, which can easily lead to gasket movement or even detachment. In addition, temperature changes may cause deformation of the gasket material, thereby affecting its fit with the cylindrical workpiece. To address these issues, a gasket with an anti-detachment structure is proposed. Utility Model Content

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A gasket with an anti-detachment structure includes a workpiece body, a gasket body is provided at the upper end of the workpiece body, and an anti-detachment mechanism is provided inside the gasket body;

[0006] The gasket body includes a washer, a sleeve interface is provided in the middle of the washer, and a number of mounting grooves are provided on the inner wall of the washer. Each of the mounting grooves is arranged in a ring at equal intervals around the mounting groove, and the interior of each mounting groove is connected to the sleeve interface.

[0007] The width of the inner wall of each of the mounting slots gradually decreases towards the sleeve interface, and the inner wall of the washer is provided with a slot on both sides of the middle part of each mounting slot.

[0008] The bottom surface of the washer is fixedly connected with several positioning protrusions, each of which is arranged equidistantly around the mounting groove in a ring shape, and each of the positioning protrusions is integrally formed with the washer.

[0009] As a further embodiment of this utility model: the anti-fall-off mechanism includes a mounting plate, and several mounting plates are provided. Each mounting plate has a locking block fixedly connected to the middle of both sides, and a limit block is fixedly connected to one end of the mounting plate.

[0010] As a further embodiment of this utility model: the overall width of the mounting plate gradually decreases in the direction away from the limiting block, and both sides of the card block are provided with rounded corners.

[0011] As a further embodiment of this utility model: the workpiece body includes a mounting column, a support plate is fixedly mounted on the outer wall of the mounting column, and a plurality of positioning holes are opened on the surface of the mounting column and above the support plate. Each of the positioning holes is arranged in a ring at equal intervals around the central axis of the mounting column. A plurality of positioning grooves are also opened on the top surface of the support plate. Each of the positioning grooves is arranged in a ring at equal intervals around the mounting column.

[0012] As a further embodiment of this utility model: the outer wall of the mounting column is connected through the inner side of the sleeve interface, and the top surface of the support plate is movable against the bottom surface of the washer, and the interior of the positioning groove is inserted into each positioning protrusion.

[0013] As a further embodiment of this utility model: the inner wall of the mounting groove is through and slidably connected to the mounting plate, the inside of the slot is engaged with the card block, and the outer wall of the washer abuts against the limiting block.

[0015] The beneficial effects of this utility model are:

[0016] (1) The present invention provides an anti-detachment structure between the workpiece body and the gasket body. The mounting plate in the structure passes through the gasket body and is connected to the inside of the workpiece body to form a mechanical interlocking structure. This design prevents the gasket from moving axially or radially through physical constraints, thereby preventing the gasket from falling off.

[0017] (2) After the mounting plate is inserted into the gasket body, the gasket material undergoes local deformation, generating elastic recovery force, which makes the gasket fit tightly against the workpiece surface and significantly increases the friction. In addition, the mounting plate also supports the inside of the gasket, thereby preventing the gasket from deforming significantly due to the influence of the external environment.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-5 As shown, a gasket with an anti-detachment structure includes a workpiece body 1, a gasket body 2 at the upper end of the workpiece body 1, and an anti-detachment mechanism 3 inside the gasket body 2. The gasket body 2 includes a washer 201, a sleeve interface 205 in the middle of the washer 201, and several mounting grooves 202 in the inner wall of the washer 201. Each mounting groove 202 is arranged equidistantly in a ring around the mounting groove 202, and the interior of each mounting groove 202 communicates with the sleeve interface 205. The width of the inner wall of each mounting groove 202 gradually decreases towards the sleeve interface 205. A retaining groove 203 is provided on both sides of the middle of each mounting groove 202 in the inner wall of the washer 201. Several positioning protrusions 204 are fixedly connected to the bottom surface of the washer 201. Each positioning protrusion 204 is arranged equidistantly in a ring around the mounting groove 202, and each positioning protrusion 204 is integrally formed with the washer 201. Figures 3-4 As shown, gasket 201 is made of flexible material, such as nitrile rubber, fluororubber, etc. The specific material needs to be purchased according to the requirements.

[0028] The anti-fall-off mechanism 3 includes mounting plates 301, and several mounting plates 301 are provided. Each mounting plate 301 has a locking block 302 fixedly connected to the center of both sides. One end of each mounting plate 301 is fixedly connected to a limiting block 303. The overall width of the mounting plate 301 gradually decreases in the direction away from the limiting block 303, and both sides of the locking block 302 are rounded. Figure 6As shown, the mounting plate 301 can be made of hard materials such as stainless steel. The insertion end of the mounting plate 301 is narrow, which makes it easier to align and insert into the mounting groove 202. The side of the locking block 302 is rounded to avoid scratching the inner wall of the mounting groove 202.

[0029] The workpiece body 1 includes a mounting post 101. A support plate 103 is fixedly mounted on the outer wall of the mounting post 101. Several positioning holes 102 are formed on the surface of the mounting post 101 above the support plate 103. Each positioning hole 102 is arranged in a ring at equal intervals around the central axis of the mounting post 101. Several positioning grooves 104 are also formed on the top surface of the support plate 103. Each positioning groove 104 is arranged in a ring at equal intervals around the mounting post 101. The outer wall of the mounting post 101 is connected through to the inner side of the sleeve interface 205. The top surface of the support plate 103 abuts against the bottom surface of the washer 201. The interior of the positioning groove 104 is inserted into each positioning protrusion 204. The inner wall of the mounting groove 202 penetrates and slides through the mounting plate 301. The interior of the slot 203 engages with the locking block 302. The outer wall of the washer 201 abuts against the limiting block 303. The end of the mounting plate 301 located away from the limiting block 303 is inserted into the positioning hole 102. The mounting plate 301, mounting groove 202, and positioning hole 102 are all the same in number. Figure 1 , Figure 2 , Figure 4 As shown, after the positioning protrusion 204 is inserted into the positioning groove 104, the extension direction of the mounting groove 202 is aligned with each positioning hole 102.

[0030] The working principle of this utility model:

[0031] When connecting the workpiece body 1 and the gasket body 2, the washer 201 is sleeved on the upper end of the mounting post 101 through the sleeve interface 205. The washer 201 slides down until it abuts against the support plate 103. The positioning protrusion 204 is inserted into the positioning groove 104 to facilitate quick positioning of the washer 201 and ensure that the extension direction of the mounting groove 202 is aligned with each positioning hole 102 respectively.

[0032] Then, the narrower end of the mounting plate 301 is inserted into the mounting groove 202. After passing through the mounting groove 202, the end of the mounting plate 301 enters the positioning hole 102. During this process, the locking block 302 presses against the inner wall of the mounting groove 202 until the limiting block 303 abuts against the edge of the washer 201. At this point, the locking block 302 and the locking groove 203 are completely aligned. The inner wall of the mounting groove 202 is restored, and the locking groove 203 and the locking block 302 are connected to each other. The above steps are repeated until the limiting blocks 303 are filled into the mounting groove 202 one by one. The workpiece body 1 and the gasket body 2 are mechanically interlocked by the mounting plate 301, thereby preventing the gasket body 2 from moving axially or radially along the workpiece body 1.
