[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a self-positioning gasket, comprising a gasket 1, an inner wall of the gasket 1 is provided with a slide groove 2, the interior of the slide groove 2 is provided with a positioning mechanism 3 for convenient positioning of the gasket 1, the gasket 1 can be quickly positioned by setting the positioning mechanism 3, which can not only prevent the gasket 1 from displacement but also facilitate the installation of the gasket 1, the interior of the gasket 1 is provided with a fixing mechanism 4 for improving the positioning effect, and the fixing mechanism 4 can improve the fixing effect of the gasket 1 to prevent the gasket 1 from moving due to equipment operation.

[0024] The positioning mechanism 3 includes a slider 31, a pull rod 32, a rubber block 33, a positioning spring 34, and a positioning plate 35; the slider 31 is slidably connected to the inner wall of the slide groove 2, and a positioning spring 34 is fixedly installed on the side wall of the slider 31. The end of the positioning spring 34 away from the slider 31 is fixedly installed on the inner wall of the slide groove 2. The slider 31 is driven to slide and reset by the elasticity of the positioning spring 34. At the same time, the pull rod 32 can drive the positioning plate 35 to move to the side close to the gasket 1 until the positioning plate 35 drives the rubber block 33 to fit the outer wall of the device. One end of the pull rod 32 is fixedly installed The side wall of the slider 31 and the other end of the pull rod 32 pass through the gasket 1 and are fixedly installed with a positioning plate 35. The gasket 1 is put on the equipment, and then the positioning plate 35 is pulled to make the positioning plate 35 drive the pull rod 32 to slide to the outside of the gasket 1. After the positioning plate 35 is pulled out, it rests against the outer wall of the equipment. The pull rod 32 is slidably connected to the penetration point of the gasket 1, and the rubber block 33 is fixedly installed on the outer wall of the positioning plate 35. By using three groups of positioning plates 35 and the rubber block 33 against the outer wall of the equipment, the gasket 1 can be firmly positioned on the equipment, which can not only prevent the gasket 1 from displacement, but also facilitate the installation of the gasket 1.

[0025] The fixing mechanism 4 comprises a ball rod 41, an inclined groove 42, a stopper 43 and a return spring 44; the ball rod 41 is slidably connected to the inner wall of the gasket 1, and the ball rod 41 passes through the gasket 1, the pull rod 32 is provided with an inclined groove 42, the outer wall of the ball rod 41 is fixedly installed with a stopper 43, one end of the ball rod 41 extends to the outside of the gasket 1 and protrudes from the gasket 1, and the other end of the ball rod 41 is fitted to the inner wall of the inclined groove 42. When the gasket 1 is installed between the two devices, the two devices will contact the two ends of the gasket 1. The two sides are fitted together, so the ball head rod 41 protruding from the gasket 1 will be squeezed into the interior of the gasket 1. At this time, the ball head rod 41 will squeeze the inclined groove 42, so that the pull rod 32 will shrink toward the inside of the slide groove 2. The outer wall of the ball head rod 41 is sleeved with a return spring 44, one end of the return spring 44 is fixedly installed on the outer wall of the limit block 43, and the other end of the return spring 44 is fixedly installed on the inner wall of the slide groove 2. When the ball head rod 41 shrinks toward the inside of the gasket 1, the limit block 43 can stretch the return spring 44.

[0026] Working principle: first, put the gasket 1 on the equipment, then pull the positioning plate 35 so that the positioning plate 35 drives the pull rod 32 to slide to the outside of the gasket 1. At the same time, the pull rod 32 will drive the slider 31 to slide inside the slide groove 2, and make the slider 31 stretch the positioning spring 34. After pulling out the positioning plate 35, it will be against the outer wall of the equipment. Then, release the positioning plate 35, and the slider 31 will slide back to its original position through the elasticity of the positioning spring 34. At the same time, the pull rod 32 can drive the positioning plate 35 to move toward the side close to the gasket 1, until the positioning plate 35 drives the rubber block 33 to fit the outer wall of the equipment. By using three sets of positioning plates 35 against the outer wall of the equipment, the gasket 1 can be firmly positioned on the equipment, which can not only prevent the gasket 1 from being displaced, but also facilitate the installation of the gasket 1.

[0027] When the gasket 1 is installed between the two devices, the two devices will fit together with the two sides of the gasket 1, so that the ball head rod 41 protruding from the gasket 1 will be squeezed into the interior of the gasket 1. At this time, the ball head rod 41 will squeeze the inclined groove 42, so that the pull rod 32 will shrink toward the inside of the slide groove 2, and at the same time, the limit block 43 can stretch the reset spring 44. At this time, the pull rod 32 will drive the positioning plate 35 to move toward the side close to the gasket 1, so that the positioning plate 35 squeezes the rubber block 33, so that the rubber block 33 fits tightly against the outer wall of the device, thereby further improving the stability of the gasket 1 and preventing the gasket 1 from moving due to the operation of the equipment.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
