[0018] The utility model will be further described in connection with the embodiments, but not as the limitation of the utility model.

[0019] Please combine Figures 1 to 5 The embodiment relates to a handrail of a vehicle comprising a rotating shaft structure with a damping link shaft sleeve, which comprises a handrail frame 1 as a fixing part, and two handrail cover plate frameworks 2 as opening and closing parts. The handrail cover plate frameworks 2 are symmetrically arranged and rotationally connected with the handrail frame 1.

[0020] The rotating shaft structure with damping link sleeve further comprises a damping 3, a rotating shaft 4 and a damping link sleeve 5. The handrail cover plate framework 2 comprises an upper plate 201 and a lower plate 202 combined with each other, wherein the back side of the upper plate 201 is provided with a mounting groove 203 for mounting the damping 3, the mounting groove 203 is a columnar groove matched with the outer ring 301 of the damping 3, part of the half of the mounting groove 203 forms an opening 203a, the edge of the opening 203a is used for cooperating with the wing plate 301a of the outer ring 301 of the damping 3, and a notch is further arranged in the mounting groove 203 and matched with the other wing plate 301a of the outer ring 301 of the damping 3. After the damping 3 is mounted in the mounting groove 203, the upper plate 201 of the handrail cover plate framework 2 and the outer ring 301 of the damping 3 can rotate together.

[0021] The lower plate 202 of the handrail cover plate framework 2 is provided with a sleeve hole, and the damping link sleeve 5 made of polyformal material is arranged in the sleeve hole. The inner ring 302 of the damping 3 is clamped with the second end of the damping link sleeve 5 through a second clamping structure, specifically, a second protruding strip 302a is arranged on the side of the inner ring 302 of the damping 3 facing the second end of the damping link sleeve 5, and a second clamping groove 501 is arranged on the second end of the damping link sleeve 5, and the second clamping groove 501 is matched with the second protruding strip 302a. During installation, after the damping 3 is mounted on the upper plate 201 of the handrail cover plate framework 2, the damping link sleeve 5 is pushed into the sleeve hole of the lower plate 202 of the handrail cover plate framework 2, so that the second clamping groove 501 is aligned with the second protruding strip 302a for clamping. In this way, the damping link sleeve 5 and the inner ring 302 of the damping 3 are connected, and the two cannot rotate.

[0022] The first end of the damping link sleeve 5 is provided with a first protruding strip 502, and after the damping link sleeve 5 is mounted on the lower plate 202 of the handrail cover plate framework 2, the first end of the damping link sleeve 5 is the end part protruding from the lower plate 202 of the handrail cover plate framework 2. A first clamping groove 101 is arranged on the handrail framework 1, and one end of the first clamping groove 101 is in an open shape. The handrail cover plate framework 2 with the damping link sleeve 5 mounted is pushed into the first clamping groove 101 through the first protruding strip 502 aligned with the opening of the first clamping groove 101, and the first protruding strip 502 and the first clamping groove 101 form a clamping connection between the damping link sleeve 5 and the handrail framework 1, so that the damping link sleeve 5 is prevented from rotating through the first clamping structure, and the inner ring 302 of the damping 3 is prevented from rotating through the second clamping structure.

[0023] The first rotation shaft hole 102 is arranged on the handrail frame 1, the second rotation shaft hole is arranged on the damping link shaft sleeve 5, and the rotation shaft 4 is connected with the inner ring 302 of the damping 3 in sequence by penetrating the first rotation shaft hole 102 and the second rotation shaft hole. The head of the rotation shaft 4 is provided with knurling 401, the position of the knurling 401 is matched with the first rotation shaft hole 102, and the accidental rotation of the rotation shaft 4 can be prevented. It should be pointed out that the position of the knurling 401 can also be arranged at the position matched with the second rotation shaft hole, and the same effect is obtained. In order to facilitate installation, the length direction of the first clamping groove 101 in the first clamping structure and the length direction of the second clamping groove 501 in the second clamping structure are both the radial direction of the rotation shaft 4.

[0024] Through the embodiment, the first clamping structure and the second clamping structure are arranged, so that the inner ring 302 of the damping 3 cannot be accidentally rotated, and the axial direction of the damping link shaft sleeve 5 is also limited, so that the axial movement of the damping link shaft sleeve 5 is prevented. The overall installation can be completed by simple clamping and insertion, the whole installation process does not need complex tools and skills, and the installation efficiency is greatly improved.
