[0002] The sealing strip is a product that plays the role of shock absorption, waterproofing, sound insulation, heat insulation, dust prevention, and fixation. It is formed in one step using a microwave vulcanization process. It has a smooth and beautiful surface. It is mainly used for static sealing at the joint between two parts. The existing polypropylene sealing strips are mostly hollow structures inside, and notches are opened on the left and right side walls of the sealing strip as a buffer structure, thereby increasing the polypropylene sealing strip's resistance to deformation.

DETAILED DESCRIPTION

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0016] Reference Figure 1-Figure 4As shown, the anti-deformation polypropylene sealing strip includes a rubber strip 1, and both side walls of the rubber strip 1 are provided with slots 2, and U-shaped moving seats 3 are slidably installed in the two slots 2 through sliding components, and the sliding components include a slide groove 8 provided in the slot 2 and a slider 9 slidably installed in the slide groove 8, and the slider 9 is fixedly connected to the moving seat 3, and the moving seat 3 is slidably installed in the slot 2 through the slider 9 and the slide groove 8, and can move horizontally in the slot 2, and a sponge cleaning block 4 is installed on the moving seat 3 through the installation component, and the sponge cleaning block 4 is slidably inserted in the slot 2 A moving hole is provided on the moving seat 3, and a rectangular block 5 is slidably installed in the moving hole. A pressing plate 6 is fixedly installed on one end of the rectangular block 5 close to the sponge cleaning block 4, and the pressing plate 6 is fixedly connected to the sponge cleaning block 4. A transmission assembly for driving the rectangular block 5 to move is provided on the moving seat 3, and the transmission assembly includes a moving block 12 slidably installed on the moving seat 3 through a translation component, a fixed block 13 fixedly installed at one end of the moving block 12, and two triangular blocks 14 symmetrically fixedly installed on the fixed block 13, and the inclined surfaces of the two triangular blocks 14 are both facing the rectangular block 5.

[0017] When it is necessary to clean the impurities in the slot 2, the moving block 12 drives the fixed block 13 to move, and then drives the triangular block 14 to move together. The inclined surface of one triangular block 14 will contact one end of the rectangular block 5. Under the action of the inclined surface, the rectangular block 5 will move toward the pressing plate 6, so that the pressing plate 6 will squeeze the sponge cleaning block 4 to deform it. After the deformation, the sponge cleaning block 4 is in tight contact with the inner wall of the slot 2. Therefore, when the moving seat 3 is moved, the sponge cleaning block 4 can better clean the impurities in the slot 2, avoiding dead corners during cleaning, and making it cleaner.

[0018] Trapezoidal grooves are provided at both ends of the movable seat 3, and the mounting assembly includes two trapezoidal wedges 10 and a plurality of positioning screws 11, both of which are fixedly mounted on the sponge cleaning block 4. A plurality of threaded holes are provided on the movable seat 3, which are respectively connected to the two trapezoidal grooves. The spacing between the two threaded holes in the same trapezoidal groove is greater than the length of the trapezoidal wedge 10, and the plurality of positioning screws 11 are respectively threadedly inserted in the plurality of threaded holes; the sponge cleaning block 4 is installed on the movable seat 3 by inserting the trapezoidal wedge 10 into the trapezoidal groove, and then the positioning screw 11 is inserted into the threaded hole, with one end extending into the trapezoidal groove, and the trapezoidal wedge 10 is located between the two positioning screws 11, thereby preventing the trapezoidal wedge 10 from being removed from the trapezoidal groove. When the sponge cleaning block 4 needs to be replaced after long-term use, the positioning screw 11 can be removed from the threaded hole, and then the trapezoidal wedge 10 can be removed from the trapezoidal groove.

[0019] The translation component includes a U-shaped slide rail 15 and a sliding block 16 fixedly mounted on the moving seat 3. The slide rail 15 is provided with a strip hole, and the sliding block 16 is slidably mounted in the strip hole. The sliding block 16 is fixedly connected to the moving block 12, and the moving block 12 is located between the moving seat 3 and the slide rail 15. A pull rope 7 is provided on the rubber strip 1, and the two ends of the pull rope 7 are respectively fixedly connected to the two moving blocks 12; the slide rail 15 and the sliding block 16 support the moving block 12 to ensure that the moving block 12 can move horizontally on the moving seat 3. When it is necessary to pull the moving blocks 12 on the two moving seats 3 at the same time, the pull rope 7 can be pulled, and the two ends of the pull rope 7 will respectively pull the two moving blocks 12 to move until the moving block 12 moves to one end of the slide rail 15, and the pull rope 7 will pull the moving seat 3 to move in the slot 2. The two moving seats 3 can be simply controlled to move simultaneously by the pull rope 7, which is easy to operate.

[0020] When it is necessary to clean the impurities in the slot 2, the rectangular block 5 is driven by the transmission assembly to move toward the pressure plate 6, so that the pressure plate 6 squeezes the sponge cleaning block 4 to deform it. After the deformation, the sponge cleaning block 4 is in tight contact with the inner wall of the slot 2, so that when the movable seat 3 is moved, the sponge cleaning block 4 can better clean the impurities in the slot 2, avoiding dead corners during cleaning and making it cleaner.
