DETAILED DESCRIPTION

[0019] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] like Figures 1 to 4As shown in the figure, the high-temperature resistant and water-proof sealer of the present utility model includes a U-shaped main body 1, a sealing lip 2, and a mounting portion 3. The sealing lip 2 is arranged on the inner wall of the U-shaped main body 1. Sealing lips 2 are provided on both opposite inner walls of the U-shaped main body 1. The sealing lip 2 is arranged obliquely relative to the U-shaped main body 1, and the included angle between the sealing lip 2 and the U-shaped main body 1 is 60 - 70°, and preferably 65°.

[0021] The material of the U-shaped main body 1 is preferably rubber, and the rubber is preferably silicone rubber. Silicone rubber can still maintain elasticity at -60°C and can be used for a long time at 200°C. Silicone rubber has excellent weather resistance, ozone resistance, and ultraviolet radiation resistance, and will not crack after long-term outdoor use. Silicone rubber can still maintain stable performance at high temperatures and will not deform or melt. The material of the mounting portion 3 is preferably silicone rubber.

[0022] The mounting portion 3 is arranged outside the U-shaped main body 1. An installation hole 4 is provided on the mounting portion 3. A through hole 3a is provided on the mounting portion 3. The through hole 3a is arranged along the axial direction of the mounting portion 3. The installation hole 4 is arranged along the radial direction of the mounting portion 3. The installation hole 4 communicates with the through hole 3a, and a bonding groove 3b is provided on the inner wall of the through hole 3a.

[0023] During the installation process, the mounting portion 3 is extruded to cause deformation of the mounting portion 3. Therefore, in this embodiment, an exhaust hole 3c is also provided on the mounting portion 3. Through the exhaust hole 3c, it is convenient to discharge the air inside the mounting portion 3, so that when the mounting portion 3 is subjected to an extrusion force, it can deform, making the installation proceed smoothly.

[0024] It further includes a clamping component A for clamping with the vehicle body. The clamping component A includes a first connecting rod 5, a second connecting rod 6, a first limiting portion 7, a second limiting portion 8, and a snap component 9. The first connecting rod 5 and the second connecting rod 6 are fixed, and the diameter of the first connecting rod 5 is larger than that of the second connecting rod 6.

[0025] The first limiting portion 7 and the second limiting portion 8 are respectively arranged on the circumferential surface of the first connecting rod 5. The diameter of the first limiting portion 7 is larger than that of the first connecting rod 5, and the diameter of the second limiting portion 8 is larger than that of the installation hole 4. Therefore, when the clamping component A passes through the installation hole 4, the mounting portion 3 is clamped between the first limiting portion 7 and the second limiting portion 8, so that the clamping component A is fixed to the mounting portion 3.

[0026] One end of the snap-fastening component 9 is connected to one end of the second connecting rod 6, and the other end of the snap-fastening component 9 is a free end. The axial direction of the snap-fastening component 9 forms an angle with the axial direction of the second connecting rod 6. After the first connecting rod 5 passes through the mounting hole 4, the first limiting portion 7 abuts against the inner wall surface of the mounting portion 3, and the first limiting portion 7 is preferably engaged with the engaging groove 3b. The second limiting portion 8 abuts against the outer wall surface of the mounting portion 3, and the second connecting rod 6 and the snap-fastening component 9 are exposed outside the mounting portion 3. During installation, a receiving cavity and an assembly hole are provided on the vehicle body. When the mounting portion 3 is fitted with the receiving cavity, and the second connecting rod 6 and the snap-fastening component 9 are inserted into the assembly hole, the snap-fastening component 9 is first compressed, and when the insertion is in place, the snap-fastening component 9 rebounds into the receiving groove provided on the wall of the assembly hole, and the snap-fastening component 9 forms an abutment with the receiving groove, so that the clamping component A is fixed to the vehicle body.

[0027] A butt portion 10 is provided at the other end of the first limiting portion 7, and a relief groove 11 is provided on the second limiting portion 8. Since the snap-fastening component 9 swings towards the second connecting rod 6 under the extrusion of the wall of the assembly hole when inserted into the assembly hole on the vehicle body, the relief groove can prevent the free end of the snap-fastening component 9 from interfering with the second limiting portion 8.

[0028] The utility model further includes a U-shaped steel strip 12, and a U-shaped hole 1a is provided on the U-shaped main body 1. The U-shaped steel strip 12 is fitted with the U-shaped hole 1a. After the U-shaped steel strip 12 is installed in the U-shaped hole 1a, when the U-shaped main body 1 is deformed under the extrusion force, the U-shaped steel strip 12 deforms along with the U-shaped main body 1. When the extrusion force on the U-shaped main body 1 is withdrawn, the elastic potential energy stored in the U-shaped steel strip 12 is released, which is beneficial to the reset of the U-shaped main body 1 and ensures the reliability of the U-shaped main body 1.

[0029] Finally, it should be noted that the above-described embodiments are only preferred embodiments of the present utility model to illustrate the technical solutions of the present utility model, rather than limiting it, let alone limiting the protection scope of the present utility model; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the protection scope of the claims.
