[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] The utility model relates to a rubber brake leather cup with double-layer skirt, which comprises a bottom-closed leather cup main body 1.

[0021] As shown in the drawing, Figures 4-5 The leather cup main body 1 is provided with an embedded groove 3 extending around the center of the leather cup main body 1, and the embedded groove 3 comprises an upper wall 302 and a lower wall 303 arranged oppositely and an inner wall 301 connecting the upper wall 302 and the lower wall 303, and the bottom of the upper wall 302 is fixedly connected with a sealing strip 4.

[0022] Furthermore, in order to reduce damage to the surface of the leather cup body 1, a leather sleeve 2 with an unsealed bottom is provided on the protruding side of the leather cup body 1.

[0023] Among them, such as Figure 6 As shown, the side of the leather sleeve 2 connected to the leather cup body 1 is provided with an insert block 5 that surrounds the center of the leather sleeve 2. The outer side of the insert block 5 is provided with a snap-in groove 6 that extends in a circle. The cross section of the combination of the insert block 5 and the snap-in groove 6 is U-shaped. The shape and size of the insert block 5 are adapted to the insert groove 3.

[0024] Among them, such as Figure 6 As shown, the snap-in groove 6 includes: a first sidewall 602 and a second sidewall 603 disposed opposite to each other, and a bottom wall 601 for connecting the first sidewall 602 and the second sidewall 603. The snap-in groove 6 is adapted to the size and shape of the sealing strip 4.
