[0003] There is an existing anti-falling automobile door sealing strip (application number: 202021573125.0). The nano waterproofing agent layer can protect and block the gap at the connection to prevent water from the outside from entering the inner cavity of the sealing strip body through the two ends of the rubber outer layer, thereby improving the overall practicality. The above-mentioned problem still exists. When the car door is in use, a sealing strip needs to be set at the door position. The setting of the sealing strip can block external rain and dust. When the sealing strip is installed, the two ends are prone to warping and falling off. In addition, different models of cars use sealing strips of different lengths. When the staff cuts them, dimensional deviations are likely to occur, which makes it inconvenient to prevent the sealing strip from falling off and adjust the length at the same time. It is inconvenient to use. When the sealing strip is used, long-term use is likely to cause aging of the sealing strip, thereby affecting the effect of the sealing strip. Utility Model Content

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings:

[0022] Embodiment 1:

[0023] See attached Figure 1-6 In the present embodiment, a sealing strip for preventing automobile doors from falling off comprises a sealing strip 1, wherein both upper and lower ends of the sealing strip 1 are fixedly connected with convex strips 3, and the convex strips 3 and one side of the outer wall of the sealing strip 1 are gap-fitted with a straight tube 12, and one side of the straight tube 12 is provided with a plate body 5, and one end of the plate body 5 is fixedly connected with a block body 6, and the outer wall gap of the block body 6 is gap-fitted with a groove block 13, the outer wall of the sealing strip 1 is fixedly connected with an anti-corrosion layer 4, one end of the sealing strip 1 is fixedly connected with a square block 11, and a groove gap is gap-fitted with an inclined block 7 on one side of the block body 6, and one end of the inclined block 7 is fixedly connected with an annular plate 8, and one side of the outer wall of the annular plate 8 is gap-fitted with an inner wall of one side of the groove block 13.

[0024] When the annular plate 8 is subjected to force, it can move up and down on the inner wall of one side of the groove block 13. The inner wall of the annular plate 8 is slidably connected with a vertical block 10. The vertical block 10 plays a limiting role when the annular plate 8 moves up and down under force. The rear end of the vertical block 10 is fixedly connected to the rear end of the inner wall of one side of the groove block 13. One end of the vertical block 10 is fixedly connected with a spring 29. The other end of the spring 29 is fixedly connected to one end of the inner wall of the annular plate 8. The spring 29 gives the annular plate 8 an inward force. A fixed structure 2 is provided on one side of the groove block 13. The fixed structure 2 is convenient for preventing the sealing strip 1 from falling off and adjusting its length at the same time, and is easy to use.

[0025] The fixing structure 2 includes a straight block 2a1, one end of which is fixedly connected to one end of the groove block 12, a slider 2a2 is slidably engaged with the inner through groove of the straight block 2a1, and the slider 2a2 plays a limiting role when the straight block 2a1 moves left and right under force, and the rear end of the slider 2a2 is fixedly connected to the rear end of the inner wall of the straight tube 12, and a rubber block 2a4 is tightly fitted on one side of the outer wall of the straight block 2a1, and one end of the rubber block 2a4 is processed with wear patterns, and one end of the rubber block 2a4 is fixedly connected to a screw rod 2a3, and one side of the outer wall of the screw rod 2a3 is threadedly connected to the inner wall of one side of the straight tube 12, so as to prevent the sealing strip 1 from falling off and adjust the length at the same time, and it is easy to use.

[0026] Working principle:

[0027] When the sealing strip is used:

[0028] The plate body 5 is fixedly connected to the car door, and the groove block 13 is pulled outward. The groove block 13 drives the straight block 2a1 to move outward. After the groove wheel 13 is inserted into the outer wall of the block body 6, the spring 29 drives the annular plate 8 to move inward, and then the inclined block 7 is inserted into the groove of the block body 6, so as to achieve connection and fixation to avoid falling off, and the screw rod 2a3 is rotated. The screw rod 2a3 drives the rubber block 2a4 to move inward. The rubber block 2a4 fits tightly with the outer wall of the straight block 2a1, so as to achieve fixation and adjustment work, and then complete the installation of the sealing strip 1. The anti-corrosion layer 4 is EPDM rubber. EPDM rubber has excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance and color stability, so as to avoid aging of the sealing strip 1 due to long-term use and affect the effect of the sealing strip 1. The setting of the anti-corrosion layer 4 on the sealing strip 1 can improve the anti-corrosion and aging resistance of the sealing strip 1.

[0029] Embodiment 2:

[0030] See attached Figure 1-6 In the present embodiment, a sealing strip for automobile door is provided to prevent it from falling off, wherein the fixing structure 2 may further include an insert rod 2b1, one side of the outer wall of the insert rod 2b1 is gapped with the inner wall of one side of the straight tube 12, the other side of the outer wall of the insert rod 2b1 is gapped with the groove at one end of the block 11, the outer wall gap of the insert rod 2b1 is gapped with a spring 2b2, the spring 2b2 gives the insert rod 2b1 an inward force, the upper and lower ends of the spring 2b2 are respectively fixedly connected with one end of the inner wall of the straight tube 12 and one side of the outer wall of the insert rod 2b1.

[0031] Working principle:

[0032] The plug rod 2b1 is pulled outward to be removed from the groove of the block 11, thereby realizing the disassembly of the sealing strip 1, and facilitating the replacement of the sealing strip 1 when it is damaged.

[0033] Although the present invention has been shown and described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein within the scope of the claims.
