[0002] A sealing strip is a material used to enclose, seal, or protect objects, typically made of flexible material. It is designed to fill or cover gaps between objects to prevent the ingress or escape of foreign matter, such as water, air, and dust. Sealing strips are widely used in various fields, including construction, automotive, electronics, and machinery.

[0003] A Chinese patent has been found to disclose a heat-resistant sealing strip for doors and windows, comprising moisture-absorbing cotton, a sealing strip body, and a sealing plate. The strip body is provided with arc-shaped grooves on both sides, and the inner surface of the arc-shaped grooves is provided with anti-slip protrusions. The top of the strip body is bonded with moisture-absorbing cotton using polyurethane waterproof adhesive. This new sealing strip has excellent heat resistance, stretch resistance, and moisture absorption properties, making it suitable for widespread use.

[0004] But in the above techniques:

[0005] The sealing strip body is connected to the sealing plate. After long-term use, the sealing strip will not fit tightly with the sealing gap. External dust and impurities can easily enter the sealing gap and affect the fit between the sealing strip and the gap. Failure to clean the dust and impurities on the outer surface of the sealing strip is not conducive to actual application.

[0006] Therefore, the utility model provides a high temperature resistant sealing strip to solve the above problems. Utility Model Content

[0018] (3) Beneficial effects

[0019] 1. Insert the high-temperature resistant sealing strip into the gap of the door, window or door panel to be installed. When the door, window or door panel rotates, it will squeeze the arc-shaped rubber part above. The arc-shaped rubber part drives the internal telescopic plate downward through the internal extrusion strip, thereby causing the extrusion plate to slide downward. The movement of the extrusion plate drives the high-temperature resistant sealing strip to fit more closely with the gap of the door, window or door panel, ensuring the tightness of the high-temperature resistant sealing strip during use and ensuring the fit of the device in the gap.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] The utility model provides a high-temperature resistant sealing strip, including a support plate 1, a trapezoidal plate 2 is provided under the support plate 1, a high-temperature resistant sealing strip 3 is provided on the lower surface of the trapezoidal plate 2, an arc-shaped rubber part 4 is fixedly installed on the upper surface of the support plate 1, and an extrusion strip 5 is provided on the inner top wall of the arc-shaped rubber part 4. Telescopic rods 6 are fixedly installed on both sides of the lower surface of the extrusion strip 5, and a first spring 7 is provided inside the telescopic rod 6. Grooves are provided at the four corners of the upper surface of the support plate 1, a second spring 8 is provided inside the groove, and a support column is fixedly installed on the upper surface of the second spring 8. A sliding plate 9 is fixedly installed on the top of the support column, and a card slot is provided on both sides of the upper surface of the sliding plate 9, which is adapted to one end of the telescopic rod 6. Driven columns 10 are fixedly installed on both sides of the lower surface of the sliding plate 9, and an extrusion plate 11 is fixedly installed on one end of the driven column 10. Columns are fixedly installed at the four corners of the upper surface of the trapezoidal plate 2, and the outer surface of the column is slidably connected to the extrusion plate 11. Blocks are fixedly installed on the upper surfaces of several extrusion plates 11.

[0030] The high-temperature resistant sealing strip 3 is embedded in the gap of the door, window or door panel to be installed. When the door, window or door panel rotates, the curved rubber part 4 on the top will be squeezed and the internal extrusion strip 5 will be driven downward. The extrusion strip 5 will drive the telescopic rod 6 below to move downward. The movement of the telescopic rod 6 causes the sliding plate 9 below to slide downward. Since the elastic coefficient of the first spring 7 is greater than the second spring 8, the sliding plate 9 drives the supporting column to slide inside the groove and squeezes the second spring 8 inside, and the telescopic rod 6 maintains its initial state. With continuous squeezing, the telescopic rod 6 will contract and squeeze the first spring 7 inside. The sliding plate 9 drives the driven column 10 to move during the downward sliding process. The driven column 10 drives the extrusion plate 11 to slide downward, so that the high-temperature resistant sealing strip 3 fits more tightly to the gap of the door, window or door panel.

[0031] The side surfaces of the two driven columns 10 are fixedly installed with side columns, and the outer surfaces of the side columns are fixedly installed with a cartridge. The two side surfaces of the cartridge are rotatably connected to the push rod 12 through a hinge seat, and the other end of the push rod 12 is rotatably connected to the telescopic plate 13 through a hinge seat. A brush plate 14 is fixedly installed at the bottom of each two telescopic plates 13. The two sides of the upper surface of the trapezoidal plate 2 are set as inclined surfaces, and the brush plate 14 is tightly attached to the upper surface of the trapezoidal plate 2. A third spring 15 is provided inside several telescopic plates 13. A card block is fixedly installed on the upper surface of the telescopic plate 13, and the internal sliding connection of the card block is a guide column 16. Support blocks are fixedly installed at both ends of the guide column 16, and the support blocks are fixedly installed on the lower surface of the support plate 1.

[0032] As the driven column 10 slides, it drives the side column to move, and the side column drives the push rod 12 to move through the clamping cylinder and the hinged seat. The push rod 12 pushes the telescopic plates 13 on both sides to the sides, and the telescopic plates 13 slide on the outer surface of the guide column 16 inside the card block, so that the telescopic plates 13 can slide stably, and the telescopic plates 13 drive the brush plates 14 at the bottom to move synchronously. When the brush plates 14 slide to the inclined surfaces on both sides of the upper surface of the trapezoidal plate 2, the third spring 15 inside the telescopic plate 13 makes the brush plates 14 always close to the trapezoidal plate 2, and effectively cleans the dust accumulated on the surface of the trapezoidal plate 2, which greatly reduces the dust from entering the gap and affecting the fit and sealing of the high-temperature resistant sealing strip 3.

[0033] The elastic coefficient of the first spring 7 is greater than that of the second spring 8 , and the elastic coefficient of the second spring 8 is greater than that of the third spring 15 .

[0034] Flexible blocks 19 are provided on both sides of the lower surface of the trapezoidal plate 2. A sealing strip 17 is fixedly installed on the surface of the flexible block 19. Both side surfaces of the sealing strip 17 are set as rectangular surfaces. Deformation grooves 18 are opened on both side surfaces of the flexible block 19. The shape of the deformation groove 18 is U-shaped.

[0035] When the high-temperature resistant sealing strip 3 and the sealing strip 17 are squeezed, the force on the sealing strip 17 will be transmitted to the flexible block 19. Since the flexible block 19 has strong flexibility and will deform along the side of the force when subjected to force, the flexible block 19 will deform at the deformation groove 18, so that the sealing strip 17 can effectively fill the joint and have a stable and reliable sealing effect.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
