[0018] The utility model is described in detail below in combination with the drawing and example.

[0019] Refer to Figure 1As shown, the sealing gasket comprises a gasket body 1 made of stainless steel material and a plurality of clamping structures, the gasket body 1 has high strength and corrosion resistance, so that the gasket body 1 has a long service life, the clamping structure comprises a bending part 2 and a fitting part 3, and the clamping structure is detachably installed on the gasket body 1 through two mounting plates 4 with consistent shape and size, the two mounting plates 4 are respectively located on both sides of the gasket body 1 and used for clamping the gasket body 1, one end of the two mounting plates 4 is fixedly connected through an elastic sheet 5, and the other end is detachably connected through a fixing piece, the cross section of the elastic sheet 5 is arc-shaped, and the mounting plate 4 and the elastic sheet 5 are fixedly connected through welding, the welding structure has high bearing capacity and stability, so that the mounting plate 4 and the elastic sheet 5 have high connection strength, then after the sealing gasket is installed and fixed, the fixing piece can be opened to release the constraint on the movable end of the mounting plate 4, then the mounting plate 4 is driven away from each other through the deformation of the elastic sheet 5 to release the clamping of the gasket body 1, so that the clamping structure and the gasket body 1 are separated, then when the next sealing gasket is installed and fixed, the gasket body 1 can be placed between the two mounting plates 4, and a force is applied to the two mounting plates 4 respectively to drive the two mounting plates 4 to approach each other, the elastic sheet 5 is deformed by the pressure applied by the two mounting plates 4 on both ends respectively, so that the mounting plate 4 and the gasket body 1 are in contact, until the mounting plate 4 and the gasket body 1 are fully fitted, the fixed end of the two mounting plates 4 is fixed through the fixing piece, so as to avoid the two mounting plates 4 from being opened away from each other, so as to realize the installation and fixation of the clamping structure on the gasket body 1, then the clamping structure can be used to assist the installation of the gasket body 1, and the operation is convenient, and the fixing and opening of the two mounting plates 4 are realized through the fixing piece, so as to realize the fixation and separation between the clamping structure and the gasket body 1, so that after the installation of the sealing gasket is completed, the clamping structure can be detached from the gasket body 1 for repeated use, and when the sealing gasket is produced, it is not necessary to additionally process the clamping structure on each gasket, so as to reduce the production cost.

[0020] Referring to Figures 1-3As shown, a plurality of insertion holes 6 are formed on the mounting piece 4, and a plurality of insertion pieces 7 are integrally formed on the sidewall of the gasket body 1 and are used to be clamped into the insertion holes 6. During the installation of the clamping structure, when the mounting piece 4 is in contact with the gasket body 1, the insertion pieces 7 are clamped into the insertion holes 6, and the insertion holes 6 limit the insertion pieces 7, which can prevent the gasket body 1 from moving or falling off during the installation process, thereby ensuring the stability of the connection between the mounting piece 4 and the gasket body 1. The fixing member is a sleeve 8, and a clamping piece 9 is arranged on the end of the mounting piece 4 away from the elastic piece 5 and is used to be clamped into the sleeve 8. A limiting member is arranged on the clamping piece 9 and is used to limit the movement of the sleeve 8. During the installation of the clamping structure, after the mounting piece 4 is in contact with the gasket body 1, the two clamping pieces 9 are clamped into the sleeve 8 at the same time, and the sleeve 8 is in contact with the mounting piece 4 on one side. The limiting member can limit the movement of the sleeve 8 and separate the clamping piece 9. The clamping piece 9 is limited in the sleeve 8, and the two clamping pieces 9 are in contact with the two sidewalls of the sleeve 8, thereby limiting the two mounting pieces 4 from moving away from each other and opening, thereby ensuring the stability of the connection between the mounting piece 4 and the gasket body 1. When the limiting member is removed from the sleeve 8, the sleeve 8 can be slid, and the clamping piece 9 is separated from the sleeve 8. The constraint of the sleeve 8 on the clamping piece 9 disappears, the elastic piece 5 deforms and returns to drive the mounting piece 4 to automatically open, thereby completing the disassembly of the clamping structure. The operation is relatively convenient.

[0021] Referring to Figure 3 As shown, the limiting member is a clamping tooth 10 arranged on the two clamping pieces 9 in the opposite direction, and the cross section of the clamping tooth 10 is triangular. The inclined surface of the clamping tooth 10 is arranged in the opposite direction of the mounting piece 4, and the clamping piece 9 has elasticity. A backspace is left between the two clamping pieces 9. During the clamping process of the clamping piece 9 into the sleeve 8, when the sleeve 8 is in contact with the clamping tooth 10, the movement of the sleeve 8 is hindered by the clamping tooth 10. If the sleeve 8 continues to move, the sleeve 8 and the clamping tooth 10 are pressed against each other, thereby forcing the two clamping pieces 9 to deflect in opposite directions. At the same time, the clamping tooth 10 is guided by the inclined surface to be clamped into the sleeve 8, until the clamping tooth 10 completely passes through the sleeve 8. The contact between the clamping tooth 10 and the sleeve 8 disappears, and the pressing force of the sleeve 8 on the clamping tooth 10 disappears. The two clamping pieces 9 deform and return, and move away from each other, thereby driving the clamping tooth 10 to return and be in contact with one side of the sleeve 8, thereby limiting the movement of the sleeve 8. The two clamping pieces 9 are pressed in the opposite direction, thereby moving close to each other, thereby driving the clamping tooth 10 to be clamped into the sleeve 8 in the opposite direction. The limiting of the sleeve 8 on the clamping tooth 10 disappears, and the sleeve 8 can be moved, so that the clamping piece 9 is separated from the sleeve 8. The fixing of the sleeve 8 on the mounting piece 4 is released. Through the contact and separation of the clamping tooth 10 and the sleeve 8, the clamping piece 9 is limited and separated in the sleeve 8. The operation is relatively convenient, thereby making the fixing and separation of the two mounting pieces 4 relatively convenient.

[0022] Referring to Figure 1、 Figure 3 As shown in the drawings, a guide inclined surface 11 is formed at one end of the fitting part 3 away from the bending part 2, and the guide inclined surface 11 can play a guiding role in the installation process of the sealing gasket. When the gasket is installed, the guide inclined surface 11 can first abut against the side wall with a seal, and gradually guide the fitting part 3 to the correct position as the installation is deepened, thereby facilitating the installation and fixation of the sealing gasket.

Any technical solution falling within the concept of the present application shall fall within the protection scope of the present application. It should be noted that, for ordinary skilled persons in the art, some improvements and refinements without departing from the principles of the present application shall also be considered as falling within the protection scope of the present application.
