In one preferred embodiment of the present application, as shown in fig. 1 to 6, a rubber gasket with a metal skeleton includes a pair of sealing bodies 1, and first ends of the two sealing bodies 1 are hinged, it is understood that the two sealing bodies 1 can relatively rotate around a hinge point.

Specifically, when using, at first dismantle the mechanical part that waits to install sealed pad and loosen, then shift out a bit space position with mechanical part's installation position, rotate two sealing bodies 1 in opposite directions and be open-phase, with its card in mechanical part's outside, then rotate relatively and draw close, the second end of two sealing bodies 1 can cooperate through joint subassembly 5 at this moment and connect, and then form closed structure, form closed sealed pad promptly and use. Therefore, the whole mechanical part is not required to be disassembled to realize the installation of the sealing gasket, and the installation efficiency is improved simply and conveniently.

In this embodiment, as shown in fig. 5, the clamping assembly 5 includes a clamping groove 501 and a clamping block 502, the clamping groove 501 is disposed at the second end of one of the sealing bodies 1, and the clamping block 502 is mounted at the second end of the other sealing body 1. When the two sealing bodies 1 rotate relatively and are propped against each other during use, the clamping blocks 502 are clamped into the clamping grooves 501 to be matched, so that the connection and the matching of the second ends of the sealing bodies 1 are realized. Of course, the clamping block 502 and the clamping groove 501 are preferably in interference fit, so that the stability of the fit can be improved.

However, in the use process, the clamping block 502 and the clamping groove 501 are in interference fit, and the sealing gasket is subjected to a great pressure during installation, so that the second end of the sealing body 1 may be separated.

In order to solve the above-mentioned problem, in one embodiment of the present application, as shown in fig. 5 and 6, the clamping assembly 5 further includes a positioning block 503 and a positioning groove 504, the positioning block 503 may be slidably mounted in the clamping block 502 through a spring, the positioning groove 504 is disposed outside one of the sealing bodies 1 and is communicated with the clamping groove 501, and the positioning block 503 and the positioning groove 504 form a clamping fit.

In order to facilitate an understanding of how the two sealing bodies 1 are connected, the working principle thereof is described below:

the positioning block 503 is extended from the clamping block 502 for a certain distance in the initial state under the elastic force of the spring. When the sealing body is installed, the positioning block 503 can be pressed and contracted into the clamping block 502, then the second ends of the two sealing bodies 1 are relatively rotated, after the clamping block 502 is inserted into the clamping groove 501 to be in place, the positioning block 503 and the positioning groove 504 are in corresponding states, and then the positioning block 503 is clamped into the positioning groove 504 under the action of the elasticity of the spring, so that the locking and installation of the second ends of the sealing bodies 1 can be realized, and the stability during installation is greatly improved. And if the two sealing bodies 1 are required to be separated, the positioning block 503 in the positioning groove 504 is pressed inwards, so that the positioning block 503 and the positioning groove 504 are separated in a staggered manner, and then the second ends of the two sealing bodies 1 are rotated and separated in opposite directions, so that the sealing gasket is detached.

In this embodiment, as shown in fig. 1, the shape of the sealing body 1 is specifically determined according to the structure of the sealing gasket, such as a rectangular sealing gasket, an annular sealing gasket and some irregular sealing gaskets in the prior art, but the present application is mainly directed to improvement of the annular sealing gasket, that is, sealing of cylindrical (shaft) parts, so that the sealing body 1 preferably adopts a semicircular ring structure.

In this embodiment, the sealing body 1 includes a semi-metal body 101 and a pair of semi-rubber bodies 102, the semi-rubber bodies 102 are mounted on two sides of the semi-metal body 101, that is, the sealing gasket is supported by using metal as a framework, which is different from the traditional sealing gasket that is made of all-rubber material, and the metal framework can better support the whole sealing gasket, thereby improving sealing performance and durability. The rigidity of the semi-metallic body 101 is such that the sealing body 1 remains in shape when subjected to external pressure or compression, ensuring a sealing effect during installation and use. In addition, the use of the metal framework can also improve the high temperature resistance and corrosion resistance of the sealing body 1, and is suitable for wider working environments.

It should be noted that, the abutting joint assembly 5 of the sealing body 1 is naturally mounted on the semi-metal body 101 of the metal skeleton, so as to ensure the firmness and stability of the sealing connection.

Specifically, as shown in fig. 2, mounting grooves 2 are formed on both sides of the semi-metal body 101, and the semi-rubber body 102 may be mounted in the mounting grooves 2 in a sticking manner, so as to achieve the combination of the semi-metal body 101 and the semi-rubber body 102. At the same time, the semi-rubber body 102 is brought into close contact with the mounting groove 2 of the semi-metal body 101, thereby enhancing the stability and durability of the assembly. Further, loosening and falling-off between the semi-metal body 101 and the semi-rubber body 102 can be effectively prevented, and reliability and service life of the whole structure are improved. Meanwhile, when the semi-metal body 101 is replaced in the later period, the strength of the semi-metal body 101 is good, so that the sealing gasket is generally aged and damaged by the semi-rubber body 102, the semi-rubber body 102 can be torn off at the moment, and then the semi-rubber body 102 is re-adhered, so that the recycling of the metal framework is realized.

Of course, in order to improve the stability of adhesion, a plurality of adhesive holes 3 may be provided on the adhesive side of the half rubber body 102, so that the contact range between the half rubber body 102 and the adhesive can be increased when the adhesion is performed, thereby increasing the firmness of the adhesion. In addition, the adhesive side of the semi-rubber body 102 may be provided with special surface treatment techniques, such as texturing or application of special adhesives, to enhance adhesion to the adhesive.

Further, at least one positioning column 4 matched with the bonding hole 3 can be arranged in the mounting groove 2, so that when the semi-rubber body 102 is pasted and mounted in the mounting groove 2, the firmness after mounting can be improved through the cooperation of the positioning column 4 and the bonding hole 3, and on the one hand, when mounting is performed, the semi-rubber body 102 and the mounting groove 2 can be correspondingly matched more accurately, so that the position and the direction of the semi-rubber body 102 are completely matched with the mounting groove 2. The design can effectively reduce errors in the installation process and improve the assembly precision and stability.

Because the two ends of the two half rubber bodies 102 are in butt fit after the sealing gasket is installed, gaps can be generated between the two half rubber bodies 102 during extrusion, and sealing performance is greatly reduced.

In order to solve the above-mentioned problem, in one embodiment of the present application, as shown in fig. 3, two ends of two semi-rubber bodies 102 are respectively provided with a protruding portion 7 and a recessed portion 6, and the protruding portion 7 and the recessed portion 6 are in plug-in fit, so that a structure capable of being connected with each other is formed, and further sealing connection fit after the two semi-rubber bodies 102 are propped against is realized, so that stability and reliability of sealing performance are ensured.

In this embodiment, an anti-oxidation coating, that is, a layer of anti-oxidation coating plated on the semi-rubber body 102 and the semi-metal body 101, may be disposed on the outside of the sealing body 1, so as to prevent the sealing body 1 from contacting with oxygen in the external environment, thereby prolonging the service life of the sealing body 1. Of course, the choice of the anti-oxidation coating can be determined according to specific requirements, and the anti-oxidation coating can be a coating with the characteristics of high temperature resistance, corrosion resistance and the like. In the use, the oxidation-resistant coating can also provide additional protection, prevent the sealing body 1 from being influenced by external factors, ensure the stability of sealing effect. By providing the oxidation-preventing coating, the reliability and durability of the sealing body 1 can be improved.

The foregoing has outlined the basic principles, main features and advantages of the present application. It will be appreciated by persons skilled in the art that the present application is not limited to the embodiments described above, and that the embodiments and descriptions described herein are merely illustrative of the principles of the present application, and that various changes and modifications may be made therein without departing from the spirit and scope of the application, which is defined by the appended claims.
