Description

Technical Field

[0001] This utility model relates to the field of sealing gasket technology, and in particular to a wear-resistant sealing gasket for mechanical hydraulic components. Background Technology

[0002] Depending on the application scenario and performance requirements, sealing rings are designed with various cross-sectional shapes to ensure specific sealing performance and operating conditions. In mechanical hydraulic components, wear-resistant sealing gaskets exhibit diverse cross-sectional shapes, with square structures being one example. However, due to the frequent movement of mechanical hydraulic structures, the gaskets installed there wear more easily than stationary gaskets. When the gasket wears to a certain extent, its thickness decreases, affecting the sealing effect between structures. Therefore, a wear-resistant sealing gasket for mechanical hydraulic components is proposed to address the aforementioned problems. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a wear-resistant sealing gasket for mechanical hydraulic components.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a wear-resistant sealing gasket for a mechanical hydraulic component, comprising a first gasket, wherein an annular groove is formed in the first gasket, and a detachable second gasket is installed in the annular groove; further comprising a compensation component for compensating for the distance between the first gasket and the second gasket when they are worn, wherein the compensation component is installed between the first gasket and the second gasket.

[0005] As a further description of the above technical solution: the compensation component includes a second fixing ring fixedly connected to the bottom wall of the second washer, and a plurality of reset protrusions are fixedly connected to the bottom end of the second fixing ring, and the plurality of reset protrusions are arranged at equal intervals.

[0006] As a further description of the above technical solution: the first washer and the second washer are limited to slide, and a plurality of reset protrusions are disposed between the first washer and the second washer, and the two ends of the plurality of reset protrusions are respectively in close contact with the first washer and the second washer.

[0007] As a further description of the above technical solution: a connecting ring is fixedly connected to one end of the first washer near the second washer, and a limiting ring is fixedly connected to one end of the connecting ring away from the first washer. The first washer slides in the annular groove in a limited manner through the cooperation of the connecting ring and the limiting ring.

[0008] As a further description of the above technical solution: the annular groove includes a first fixing ring, and the top wall of the first fixing ring is provided with multiple sets of first recesses, second recesses and third recesses in sequence, and the multiple sets of first recesses, second recesses and third recesses are arranged in an annular arrangement.

[0009] As a further description of the above technical solution: the height of the first recess, the second recess, and the third recess gradually increases, and the reset protrusion has an arc surface structure and is adapted to the size of the first recess, the second recess, and the third recess.

[0010] This utility model has the following beneficial effects:

[0011] 1. Compared with the prior art, this wear-resistant sealing gasket for mechanical hydraulic components, by setting a compensation component, allows the entire device to be installed in the designated position during use. If the outer wall of the first or second gasket is worn, the compensation component will push the two gaskets outward to make up for the missing distance, thereby enhancing the contact effect and further extending the service life of the sealing gasket; and multiple reset protrusions can ensure that the first and second gaskets are subjected to uniform force.

[0012] 2. Compared with the prior art, this wear-resistant sealing gasket for a mechanical hydraulic component features multiple sets of first, second, and third recesses with gradually increasing heights. When the arc-shaped structure is within the first recess, the thickness between the first and second gaskets is the thinnest, and when the arc-shaped structure is within the third recess, the thickness between the first and second gaskets is the thickest. This allows the gasket thickness to be adjusted according to current installation requirements, reducing limitations in usage scenarios. Furthermore, the joints between the multiple recesses are smoothly transitioned, facilitating the adjustment and resetting protrusion to slide into different recesses. Attached Figure Description

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-7 The present invention provides a wear-resistant sealing gasket for a mechanical hydraulic component: including a first gasket 1, an annular groove 3 is provided in the first gasket 1, and a detachable second gasket 2 is installed in the annular groove 3; it also includes a compensation component for compensating for the distance between the first gasket 1 and the second gasket 2 when they are worn, and the compensation component is installed between the first gasket 1 and the second gasket 2.

[0024] The compensation component includes a second fixing ring 8 fixedly connected to the bottom wall of the second washer 2. The bottom end of the second fixing ring 8 is fixedly connected to a plurality of reset protrusions 9, which are arranged at equal intervals. The first washer 1 and the second washer 2 are limited to slide, and the plurality of reset protrusions 9 are located between the first washer 1 and the second washer 2. The two ends of the plurality of reset protrusions 9 are in close contact with the first washer 1 and the second washer 2, respectively. A connecting ring 10 is fixedly connected to the end of the first washer 1 near the second washer 2, and a limiting ring 11 is fixedly connected to the end of the connecting ring 10 away from the first washer 1. The first washer 1 is limited to slide in the annular groove 3 through the cooperation of the connecting ring 10 and the limiting ring 11. By setting a compensation component between the first washer 1 and the second washer 2, and because the reset protrusion 9 is made of elastic material, when the limiting sliding fit is located between the first washer 1 and the second washer 2, it is ensured that the first washer 1 and the second washer 2 are always in an outwardly compressed state. During use, the entire device only needs to be installed in the designated position. If the outer wall of the first washer 1 or the second washer 2 is worn, the compensation component will push the two washers outward to make up for the missing distance, thereby enhancing the contact effect and further extending the service life of the sealing gasket. In addition, the multiple reset protrusions are arranged in a ring to ensure that the first washer 1 and the second washer 2 are subjected to uniform force.

[0025] The annular groove 3 includes a first fixing ring 4. Multiple sets of first recesses 5, second recesses 6, and third recesses 7 are sequentially formed on the top wall of the first fixing ring 4. These multiple sets of first recesses 5, second recesses 6, and third recesses 7 are arranged in a ring, with the heights of the first recesses 5, second recesses 6, and third recesses 7 gradually increasing. The reset protrusion 9 has an arc-shaped structure 12, which is adapted to the dimensions of the first recesses 5, second recesses 6, and third recesses 7. By setting the first fixing ring 4, and because the top wall of the first fixing ring 4 has multiple sets of first recesses 5, second recesses 6, and third recesses 7 with gradually increasing heights, and the bottom end of the reset protrusion 9 has an arc-shaped structure 12, adjustment can be achieved by... Rotate the first washer 1 or the second washer 2 to make the first washer 1 or the second washer 2 rotate. During the rotation, the arc-shaped structure 12 switches between the first recess 5, the second recess 6 and the third recess 7. When the arc-shaped structure 12 is in the first recess 5, the thickness between the first washer 1 and the second washer 2 is the thinnest. When the arc-shaped structure 12 is in the third recess 7, the thickness between the first washer 1 and the second washer 2 is the thickest. In this way, the thickness of the washer can be adjusted according to the current installation requirements, reducing the limitation of the usage scenario. In addition, the connection between the multiple recesses is a smooth transition, which facilitates the adjustment and reset protrusion 9 to slide into different recesses.

[0026] Working principle: During use, simply install the entire device in the designated position. If the outer wall of the first gasket 1 or the second gasket 2 is worn, the compensation component will push the two gaskets outward to make up for the missing distance, thereby enhancing the contact effect and further extending the service life of the sealing gasket.

[0027] During adjustment, the first washer 1 or the second washer 2 is rotated. During the rotation, the arc-shaped structure 12 switches between the first recess 5, the second recess 6, and the third recess 7. When the arc-shaped structure 12 is in the first recess 5, the thickness between the first washer 1 and the second washer 2 is the thinnest. When the arc-shaped structure 12 is in the third recess 7, the thickness between the first washer 1 and the second washer 2 is the thickest. The thickness of the washer is adjusted according to the current installation requirements.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
