[0012] In the above-mentioned rubber automobile tailgate protection sleeve, the outer walls of the first connecting portion 2 and the second connecting portion 3 are both provided with an annular groove 21 for binding the clamp ring / connecting belt.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. The protective sleeve body of the utility model is telescopically adjustable, so the protective sleeve body can be telescopically movable with the movable end of the tail plate cylinder to be adjusted accordingly, so as to better wrap and conceal the tail plate cylinder, prevent dust, rain and other foreign objects from affecting the tail plate cylinder, effectively play a protective effect, and extend the maintenance cycle and service life of the tail plate cylinder, and have a good market prospect. In addition, the utility model also has the characteristics of simple structure and low manufacturing cost.

[0015] 2. The main body of the protective sleeve adopts a corrugated structure design, which can achieve flexible extension and contraction when the movable end of the tail plate cylinder is ejected and retracted, and can also control the deformation of the main body of the protective sleeve to the maximum extent during reciprocating motion.

[0016] 3. The protective sleeve body is provided with an air-filling hole connected to the inner cavity of the protective sleeve body, so that when the protective sleeve body is freely extended and compressed, the protective sleeve body will not expand and deform, and it is also convenient for the protective sleeve body to reciprocate.

[0017] 4. The main body of the protective tube sleeve is made of chloroprene rubber, which has better flame retardant effect than plastic. Rubber also has good elasticity and can recover after being squeezed without permanent deformation, failure or damage. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings, wherein:

[0019] Figure 1 It is a three-dimensional diagram of the utility model.

[0020] Figure 2 It is a cross-sectional view of the utility model. DETAILED DESCRIPTION

[0021] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1 , 2As shown, the utility model is a rubber automobile tailgate protective sleeve, comprising a protective sleeve body 1 that is telescopically adjustable, wherein the two end portions of the protective sleeve body 1 are respectively provided with a first connection portion 2 and a second connection portion 3, wherein the first connection portion 2 can be directly or indirectly connected to the fixed end of the tailgate cylinder, and the second connection portion 3 can be directly or indirectly connected to the movable end of the tailgate cylinder. In the utility model, the protective sleeve body is telescopically adjustable, and the protective sleeve body can be telescopically movable with the movable end of the tailgate cylinder to adjust accordingly, so as to better wrap and conceal the tailgate cylinder, prevent dust, rain and other foreign objects from affecting the tailgate cylinder, effectively play a protective effect, and at the same time extend the maintenance cycle and service life of the tailgate cylinder, and have a good market prospect. In addition, the utility model also has the characteristics of simple structure and low manufacturing cost.

[0023] The protective sleeve body 1 is arranged in a corrugated structure, which can realize flexible extension and contraction when the movable end of the tail plate cylinder is pushed out and retracted, and can also control the deformation of the protective sleeve body to the maximum extent during reciprocating motion.

[0024] The protective tube body 1 is made of chloroprene rubber, which has better flame retardant effect than plastic, and rubber also has better elasticity, and can recover after being squeezed without permanent deformation, failure or damage. Chloroprene rubber is an elastomer produced by α-polymerization of chloroprene (2-chloro-1,3-butadiene) as the main raw material.

[0025] The protective sleeve body 1 is provided with an air-filling hole 4 which is connected to the inner cavity of the protective sleeve body 1 , so that the protective sleeve body will not expand or deform when the protective sleeve body is freely extended and compressed, and the reciprocating motion of the protective sleeve body is also facilitated.

[0026] Furthermore, the air-injection hole 4 is arranged at a position on one side of the protective sleeve body 1 close to the first connection part 2 and / or the second connection part 3, so that when the protective sleeve body 1 is extended or contracted for the first time, the air-injection hole is opened to perform air-injection. Figure 2 As shown, the air supplement hole 4 is located at the corrugated position, and when the protective sleeve body 1 is in the state of contraction, the air supplement hole 4 is closed.

[0027] In order to reduce the number of assembly steps and lower the manufacturing cost, the protective sleeve body 1, the first connecting portion 2 and the second connecting portion 3 are an integral structure formed in one piece.

[0028] For the purpose of convenient and reliable connection, the outer walls of the first connecting portion 2 and the second connecting portion 3 are both provided with an annular groove 21 for binding the clamp ring / connecting belt.
