[0024] By setting the mounting block 3, the mounting block 3 can support the pressure-bearing rubber strip 4. When the vehicle door is closed, the pressure-bearing rubber strip 4 will be squeezed, so that the inner surface of the first cavity 5 presses the top plate 8 downward, and then the first elastic plate 6 and the second elastic plate 7 are elastically deformed, so that the first elastic plate 6 and the second elastic plate 7 can push the top plate 8 upward, so that the top plate 8 pushes the inner surface of the first cavity 5 upward, and then the pressure-bearing rubber strip 4 can fit tightly on the outer surface of the vehicle door, so as to play a good sealing role.

[0025] A reinforcing plate 11 is fixedly installed inside the left end of the installation rubber strip 2 , and the length of the reinforcing plate 11 is the same as that of the installation rubber strip 2 .

[0026] By providing the reinforcing plate 11 , the reinforcing plate 11 can improve the strength of the installation rubber strip 2 , thereby preventing the installation rubber strip 2 from being damaged when repeatedly squeezed.

[0027] An elastic rubber tube 12 is fixedly mounted on the top of the right end of the installation rubber strip 2 , and a circular hole 22 is opened on the outer surface of the elastic rubber tube 12 .

[0028] By providing the elastic hose 12 , when the vehicle door is closed, the elastic hose 12 can be squeezed so that the air inside the elastic hose 12 is blown out through the circular hole 22 , thereby blowing away dust at the connection between the elastic hose 12 and the door frame 1 .

[0029] A connecting block 13 is fixedly installed on the top of the inner surface of the installation rubber strip 2 , a friction block 14 is fixedly installed on the bottom of the connecting block 13 , and the bottom of the friction block 14 is movably connected to the upper surface of the door frame 1 .

[0030] The connection block 13 faces leftward, so that the installation strip 2 as a whole can be installed very smoothly.

[0031] The bottom of the friction block 14 is provided with anti-skid grooves 15 , and the anti-skid grooves 15 are arranged at equal distances.

[0032] By providing the anti-slip groove 15 , the friction between the friction block 14 and the door frame 1 is increased, thereby preventing the entire installation rubber strip 2 from being separated from the outer surface of the door frame 1 due to vibration.

[0033] A first support plate 16 is fixedly installed on the right side of the top of the friction block 14 , and the top of the first support plate 16 is fixedly connected to the right side of the connecting block 13 .

[0034] By providing the first support plate 16 , the first support plate 16 can push the friction block 14 downward after elastic deformation, so that the friction block 14 can fit more closely with the door frame 1 , thereby increasing the friction between the friction block 14 and the door frame 1 .

[0035] Among them, an extrusion block 17 is fixedly installed on the left side of the inner surface of the installation rubber strip 2, and the outer surface of the extrusion block 17 is movably connected to the outer surface of the door frame 1.

[0036] By providing the extrusion block 17 , the extrusion block 17 can clamp the door frame 1 , thereby increasing the connection points and friction between the installation strip 2 and the door frame 1 , improving the stability of the installation strip 2 , and preventing the installation strip 2 from falling off.

[0037] Among them, an anti-slip block 18 is fixedly installed on the bottom of the inner surface of the installation rubber strip 2, the top of the anti-slip block 18 is movably connected to the outer surface of the door frame 1, a second support plate 19 is fixedly installed on the left side of the anti-slip block 18, a side panel 20 is fixedly installed on the bottom of the right side of the installation rubber strip 2, the top of the side panel 20 is movably connected to the outer surface of the door frame 1, and a pull plate 21 is fixedly installed on the bottom of the side panel 20.

[0038] The operator can pull the pull plate 21 downward so that the pull plate 21 drives the bottom of the installation strip 2 to deform, thereby making the anti-slip block 18 and the side plate 20 break away from the contact with the door frame 1, making it convenient for the operator to disassemble the installation strip 2 as a whole.

[0039] The working principle and use process of this utility model:

[0040] When the door is closed, the top of the friction block 14 will be squeezed, so that the inner surface of the first cavity 5 squeezes the top plate 8 downward, and then the top plate 8 drives the first elastic plate 6 and the second elastic plate 7 to undergo elastic deformation, so that the first elastic plate 6 and the second elastic plate 7 can push the top plate 8 upward under the action of elastic force, so that the compressed rubber strip 4 can fit tightly with the door, thereby improving the overall sealing effect of the installation rubber strip 2. After being squeezed, the arc plate 9 will also push the compressed rubber strip 4 upward under the action of elastic recovery, so that the compressed rubber strip 4 has multi-point elastic support, thereby improving the overall service life of the compressed rubber strip 4. When the door is closed, the elastic hose 12 will be squeezed, so that the air inside the elastic hose 12 is discharged through the circular hole 22, and then the dust at the connection between the elastic hose 12 and the door frame 1 can be blown away, thereby preventing dust from entering the interior of the installation rubber strip 2, improving the sealing between the installation rubber strip 2 as a whole and the door frame 1, and ensuring better sealing, sound insulation and other properties of the automobile door frame sealing strip.

[0041] Since the connecting block 13 and the anti-detachment block 18 are oriented to the left, the installation of the installation strip 2 as a whole is very smooth. When the installation strip 2 as a whole moves to the left, the movement direction is opposite to the direction of the connecting block 13 and the anti-detachment block 18, thereby increasing the friction between the friction block 14, the anti-detachment block 18 and the door frame 1, thereby preventing the installation strip 2 from falling off as a whole, thereby ensuring the overall stability of the installation strip 2.
