[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] This utility model provides a technical solution: such as Figure 1 , Figure 2 As shown in Figure 4, in this embodiment, a heat-resistant silicone rubber sealing assembly for improving sealing performance includes a sealing strip individual 1. A connecting assembly 5 is installed inside the sealing strip individual 1. The connecting assembly 5 includes a first skeleton 501 and a second skeleton 502 disposed inside the sealing strip individual 1. Both the first skeleton 501 and the second skeleton 502 are L-shaped and their recessed portions are close to each other. A connecting pin 504 is provided at one end of the first skeleton 501 and the second skeleton 502. A slot 503 adapted to the connecting pin 504 is opened inside the other end of the first skeleton 501 and the second skeleton 502.

[0021] The sealing strip individual 1 is provided with a combination component 6 on its exterior. The combination component 6 includes a receiving groove 601 provided on the top of one outer wall and a receiving groove 602 provided on the bottom of the other outer wall of the sealing strip individual 1. A protrusion 603 is provided on the top of one outer wall of the sealing strip individual 1 and a protrusion 604 is provided on the bottom of the other outer wall of the sealing strip individual 1. The receiving groove 601 is fitted outside the protrusion 604 and the receiving groove 602 is fitted outside the protrusion 603.

[0022] According to the requirements, several individual sealing strips 1 are spliced ​​together to the required length. One end of the individual sealing strip 1 is grasped and brought closer to another individual sealing strip 1. The portion of the individual sealing strip 1 outside the slot 503 is pushed outward. Then, the end of the connecting pin 504 is inserted into the slot 503. The two individual sealing strips 1 will then be connected. Since the skeleton 1 501 extends into the interior of the individual sealing strip 1, when the two individual sealing strips 1 are connected, their ends will fit tightly together, which helps to ensure the sealing performance. Conversely, the individual sealing strip 1 can be removed. Then, the entire sealing element is wrapped around the outside of the rod, and the second protrusion 604 is inserted into the inside of the receiving groove 1 601. The second receiving groove 602 will be fitted over the outside of the first protrusion 603. The sealing element will also be evenly distributed on the outside of the pipe and will not have gaps during use, thus ensuring the sealing performance.

[0023] like Figure 1 and Figure 3 As shown, a corrugated groove 2 is provided on one side of the outer wall of the sealing strip 1, which increases the contact area and pressure distribution points with the sealed surface, and significantly improves the sealing effect.

[0024] like Figure 2 As shown, one side of the outer wall of skeleton 501 has several equally spaced extension grooves 3, and one side of the outer wall of skeleton 502 has several equally spaced extension grooves 4, making it easier to bend skeleton 501 and skeleton 502.

[0025] like Figure 1 As shown, the sealing strip 1 is made of fluorosilicone rubber and contains polyborosiloxane. When polyborosiloxane (PBS) and fluorosilicone rubber are blended in a 3:7 ratio, the compression set is reduced to 8%.

[0026] like Figure 1 As shown, the sealing strip 1 contains fumed silica, phenyl and iron oxide red. The addition of fumed silica (particle size 12nm) and iron oxide red forms a synergistic system, creating a three-dimensional heat-resistant network. The addition of phenyl can improve the thermal stability of the main chain.

[0027] like Figure 4 As shown, the end edge of the connecting pin 504 is set with an arc angle of 505, which makes the connection process more convenient and eliminates the need for trial and error in docking.

[0028] This utility model provides a heat-resistant silicone rubber sealing component with improved sealing performance. The specific working principle is as follows:

[0029] When the device is in operation, firstly, according to the requirements, several sealing strips 1 are spliced ​​together to the required length. Grasp one end of the sealing strip 1 and move it towards another sealing strip 1. Push the portion of the sealing strip 1 outside the slot 503 outward. Then, insert the end of the connecting pin 504 into the slot 503. The two sealing strips 1 will then be connected. Since the skeleton 1 501 extends into the interior of the sealing strip 1, when the two sealing strips 1 are connected, their ends will fit tightly together, which helps to ensure sealing. Conversely, the individual sealing strips 1 can be removed. Then, the sealing element is wrapped around the outside of the rod, and the second protrusion 604 is inserted into the inside of the receiving groove 1 601. The second receiving groove 2 602 will be fitted over the outside of the first protrusion 603. The sealing element will also be evenly distributed on the outside of the pipe and will not have gaps during use, thus ensuring sealing.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
