Description

Technical Field

[0001] The utility model relates to the technical field of sealing strips, in particular to a high temperature resistant sealing strip. Background Art

[0002] A high temperature sealing strip refers to a sealing material used to maintain sealing performance in a high temperature environment. This sealing strip is usually made of high temperature resistant materials, such as silicone rubber, fluororubber or other special high temperature materials. Its design and material selection can maintain good elasticity and chemical resistance under high temperature conditions, ensuring that there will be no sealing failure or leakage in a high temperature environment. This sealing strip is commonly used in automotive engines, industrial furnaces, high temperature pipelines and other applications that need to maintain sealing in a high temperature environment;

[0003] After searching, a Chinese patent with the announcement number of CN217355535U discloses a high temperature resistant sealing strip. The patent records that by setting a magnet, the conical convex surface on the lower surface of the first fixing frame is inserted into the conical groove surface on the upper surface of the second fixing frame, and the two magnets are attracted to each other, so that the first fixing frame and the second fixing frame can still form a seal when slightly deformed, thereby solving the problem of the sealing strip slightly deformed and causing rebound, resulting in poor sealing effect.

[0004] In this solution, although deformation is prevented by the mutual attraction of magnets, dust and impurities are easily accumulated in the sealed gap when the sealing strip is assembled, which will affect the tightness of the seal. If the dust and impurities on the sealing strip cannot be removed in time, there will be certain performance problems. In order to solve this technical problem, the utility model proposes a high temperature resistant sealing strip. Summary of the invention

[0022] The connecting block 5 is stuck in the corner of the connecting plate 3, and one end of the connecting block 5 is inserted into the slide groove 11. At the same time, the bottom end of the connecting block 5 is installed on the connecting plate 3 through the fixing column 6. When one end of the connecting block 5 is inserted into the slide groove 11, the thread groove 10 is aligned with the position of the slide groove 8. The connection is achieved by passing the thread column 9 through the slide groove 8 and rotating it in the thread groove 10. In this way, when the connecting plate 3 is pushed, the connecting plate 3 will drive the cleaning strip 4 and the cleaning strip 12 to slide inside the sealing strip 1, and clean the sealing strip 1 and the plastic strip 2 to prevent dust and impurities from affecting the sealing effect. The movement of the connecting plate 3 is ensured in the same direction through the connecting block 5 in the slide groove 11 and the slide groove 8. This design makes the sealing strip 1 and the plastic strip 2 fit closely to the object, improving the sealing effect.

[0023] Embodiment 2: The difference between this embodiment and embodiment 1 lies in that, a groove 13 is provided inside each of the cleaning strip 1 4 and the cleaning strip 2 12 , and the connecting plate 3 corresponds to the groove 13 and is slidably connected in the groove 13; a pair of insertion holes 15 is provided on the inner side wall of the cleaning strip 2 12 , and a pair of plug posts 16 are fixedly connected to the outer side wall of the connecting plate 3 , and the plug posts 16 correspond to the insertion holes 15 , and the plug posts 16 are slidably connected in the insertion holes 15 , an inner groove 14 is provided on the inner side wall of the cleaning strip 2 12 , and a plug block 17 is fixedly connected to the outer side wall of the connecting plate 3 , and the plug block 17 is located between the plug posts 16 on both sides , and the plug block 17 corresponds to the inner groove 14 , and the plug block 17 is slidably connected in the inner groove 14 .

[0024] When using the sealing strip 1, first slide and plug the upper and lower dust cleaning strips 4 at the two ends of the connecting plate 3.

In this way, through the cooperation between them, the effect of rapid assembly is achieved.

[0025] When working, when the staff uses the sealing strip 1, they first slide and plug the upper and lower dust cleaning strips 1 4 at the upper and lower ends of the connecting plate 3. At this time, the connecting plate 3 will be plugged into the groove 13. At this time, the plug hole 15 at the bottom of the dust cleaning strip 2 12 and the inner groove 14 are aligned with the plug column 16 and the plug block 17 on the connecting plate 3, and directly inserted into them. At this time, through the cooperation between them, the effect of rapid assembly is achieved. After the assembly is completed, the connecting block 5 is clamped in the corner of the connecting plate 3, and one end of the connecting block 5 is inserted into the slide groove 2 11. At the same time, the bottom end of the connecting block 5 is installed on the connecting plate 3 through the fixing column 6. When one end of the connecting block 5 is inserted into the slide groove 2 11 When the sealing strip 1 is in the sealing state, the threaded groove 10 is aligned with the position of the slide groove 18. The threaded column 9 is passed through the slide groove 18 and rotated to be installed in the threaded groove 10. At this time, the connecting plate 3 is pushed. The connecting plate 3 will drive the cleaning strip 1 4 and the cleaning strip 2 12 to slide inside the sealing strip 1, and clean the sealing strip 1 and the plastic strip 2 to prevent dust and impurities from entering the gap and affecting the fit. When the connecting plate 3 moves, it will be in the slide groove 2 11 and the slide groove 1 8 through the connecting block 5, thereby ensuring that the connecting plate 3 is in the same direction when moving. Through the cooperation between them, the sealing strip 1, the plastic strip 2 and the object are tightly fitted, thereby improving the sealing effect.
