Description

Technical Field

[0001] The utility model belongs to the technical field of fastening fittings, and particularly relates to a sealing gasket. Background Art

[0002] A gasket is an important sealing element, widely used in various industrial fields to prevent leakage of fluids or gases from joints. They are usually placed between the contact surfaces of two objects (such as pipe flanges, valve covers, etc.), and maintain a tight contact through the pressure exerted by fasteners (such as bolts), thereby achieving effective sealing.

[0003] Traditional gaskets are usually integrally formed with a fixed thickness, making it difficult to meet the installation requirements in different installation environments. When the current gasket thickness is insufficient, it is often necessary to increase the number of gaskets to achieve installation. In this case, if there are deviations in the installation of multiple gaskets, gaps are likely to occur between adjacent gaskets, affecting the sealing effect. Therefore, traditional gaskets need to be improved. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a sealing gasket for the above-mentioned existing technical problems. This sealing gasket can adjust the overall thickness to meet the installation requirements in different environments, and has a wide range of applications.

[0005] In view of this, the utility model provides a sealing gasket, including:

[0006] An upper gasket, with a lower gasket provided below the upper gasket;

[0007] An adjusting block, the upper surface of the adjusting block is slidably connected to the bottom surface of the upper gasket, and the bottom surface of the adjusting block is an inclined surface;

[0008] A fixing block, the fixing block is provided on the lower gasket, and the upper surface of the fixing block is an inclined surface that cooperates with the bottom surface of the adjusting block. When the fixing block moves relative to the adjusting block along the inclined direction of the inclined surface, the distance between the upper gasket and the lower gasket can be changed;

[0009] An installation hole, which sequentially penetrates the upper gasket, the adjusting block, the fixing block, and the lower gasket;

[0010] A locking assembly, which is used to lock the upper gasket, the adjusting block, the fixing block, and the lower gasket in the current position. When the relative positions of the adjusting block and the fixing block need to be adjusted, the locking assembly can loosen the upper gasket, the adjusting block, the fixing block, and the lower gasket.

[0011] In this technical solution, when it is necessary to adjust the overall thickness of the sealing gasket, first loosen the upper gasket, the adjusting block, the fixing block, and the lower gasket by the locking assembly. At this time, the adjusting block can slide relative to the upper gasket. During the process of the adjusting block and the fixing block moving relative to each other from the lower part of the inclined surface to the upper part of the inclined surface, the overall thickness of the sealing gasket increases. During the process of the adjusting block and the fixing block moving relative to each other from the upper part of the inclined surface to the lower part of the inclined surface, the overall thickness of the sealing gasket decreases. After adjusting the overall thickness of the sealing gasket to an appropriate thickness, lock the upper gasket, the adjusting block, the fixing block, and the lower gasket by the locking assembly, and the thickness adjustment of the sealing gasket is completed.

[0012] In the above technical solution, further, an adaptation groove is provided on the side wall of the mounting hole on the adjusting block, and the adaptation groove is located in the sliding direction of the adjusting block.

[0013] In the above technical solution, further, the locking assembly includes:

[0014] Two groups of connection holes, which are respectively arranged on the adjusting block and on both sides of the mounting hole. Each group of mounting holes includes a plurality of mounting holes distributed at intervals along the sliding direction of the adjusting block, and the mounting holes penetrate through the upper and lower surfaces of the adjusting block;

[0015] Two groups of screw holes, which are respectively arranged on the fixing block and on both sides of the mounting hole. Each group of screw holes includes a plurality of screw holes corresponding one by one to the mounting holes;

[0016] Two groups of through holes are provided on the upper gasket, and the two groups of through holes are respectively distributed on both sides of the mounting hole;

[0017] Two groups of screw rods, and the threaded ends of each group of screw rods sequentially pass through a group of through holes, a corresponding number of connection holes and are threadedly connected to a corresponding number of screw holes.

[0018] In the above technical solution, further, a ring groove is provided on the upper surface of the upper gasket, the through hole is provided in the ring groove, and the fixed end of the screw rod is hidden in the ring groove.

[0019] In the above technical solution, further, a guiding groove is provided on the bottom surface of the upper gasket along the sliding direction of the adjusting block, and a guiding block is provided on the upper surface of the adjusting block, and the guiding block is slidably arranged in the guiding groove.

[0020] In the above technical solution, further, the height of the guiding block is less than the depth of the guiding groove.

[0021] The beneficial effects of the present utility model are:

[0022] 1. Through the cooperation of the upper gasket, the adjusting block, the fixing block, and the lower gasket, relative sliding can occur between the adjusting block and the upper gasket. The distance between the upper gasket and the lower gasket can be adjusted through the cooperation of two inclined surfaces between the adjusting block and the fixing block, thereby adjusting the overall thickness of the sealing gasket. This can meet the installation requirements in different environments and expand the applicable range of the sealing gasket.

[0023] 2. By designing the locking assembly as the cooperation of two sets of connection holes, two sets of screw holes, two sets of through holes, and two sets of screw rods, the threaded end of the screw rod passes through a set of through holes and a connection hole in sequence and then is threadedly connected to a screw hole to lock the entire sealing gasket. Loosening the screw rod so that the threaded end of the screw rod withdraws from the screw hole can loosen the entire sealing gasket. The operation is simple, and it is convenient to switch between loosening and locking the entire sealing gasket.

[0024] 3. By providing a guiding groove and a guiding block between the upper gasket and the adjusting block for cooperation, the sliding of the adjusting block relative to the upper gasket is limited and guided. At the same time, the height of the guiding block is designed to be less than the depth of the guiding groove, so that the upper surface of the adjusting block can fit with the bottom surface of the upper gasket, improving the overall sealing performance of the sealing gasket.

[0035] Embodiment 1

[0036] As Figures 1-5 shown, this embodiment provides a sealing gasket, including: upper gasket 1, lower gasket 2, adjusting block 3, fixed block 4, mounting hole 5, locking assembly 6.

[0037] A lower gasket 2 is provided below the upper gasket 1, and both the upper gasket 1 and the lower gasket 2 are annular bodies.

[0038] Please refer to Figure 3 , the upper surface of the adjusting block 3 is slidably connected to the bottom surface of the upper gasket 1, and the bottom surface of the adjusting block 3 is an inclined surface.

[0039] Please refer to Figure 2 , the bottom surface of the fixed block 4 is fixedly connected to the upper surface of the lower gasket 2, and the upper surface of the fixed block 4 is an inclined surface that cooperates with the bottom surface of the adjusting block 3. When the fixed block 4 moves relative to the adjusting block 3 along the inclined direction of the inclined surface, the distance between the upper gasket 1 and the lower gasket 2 can be changed.

[0040] Holes are also provided in the middle of the adjusting block 3 and the fixing block 4. The holes in the middle of the upper gasket 1, the adjusting block 3, the fixing block 4, and the lower gasket 2 together form the mounting hole 5, which is mainly used for the fastener to pass through when the sealing gasket is in use. Please refer to Figure 3 On the side wall of the hole in the middle of the adjusting block 3, an adaptation groove 7 is provided. The adaptation groove 7 is located in the sliding direction of the adjusting block 3. The adaptation groove 7 is provided to ensure that the mounting hole 5 on the sealing gasket remains unobstructed after the adjusting block 3 slides relative to the upper gasket 1.

[0041] The locking assembly 6 is used to lock the upper gasket 1, the adjusting block 3, the fixing block 4, and the lower gasket 2 in their current positions. When the relative positions of the adjusting block 3 and the fixing block 4 need to be adjusted, the locking assembly 6 can loosen the upper gasket 1, the adjusting block 3, the fixing block 4, and the lower gasket 2.

[0042] In this embodiment, when the overall thickness of the sealing gasket needs to be adjusted, first loosen the upper gasket 1, the adjusting block 3, the fixing block 4, and the lower gasket 2 by the locking assembly 6. At this time, the adjusting block 3 can be slid relative to the upper gasket 1. During the process of the adjusting block 3 and the fixing block 4 moving relative to each other from the lower part of the inclined plane to the upper part of the inclined plane, the distance between the upper gasket 1 and the lower gasket 2 increases, so that the overall thickness of the sealing gasket increases; during the process of the adjusting block 3 and the fixing block 4 moving relative to each other from the upper part of the inclined plane to the lower part of the inclined plane, the distance between the upper gasket 1 and the lower gasket 2 decreases, so that the overall thickness of the sealing gasket decreases. After adjusting the overall thickness of the sealing gasket to an appropriate value, use the locking assembly 6 to lock the upper gasket 1, the adjusting block 3, the fixing block 4, and the lower gasket 2, and the thickness adjustment of the sealing gasket is completed.

[0043] The design of adjustable thickness of the sealing gasket can meet the installation requirements in different environments and expand the application range of the sealing gasket.
