DETAILED DESCRIPTION

[0019] The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict. For the convenience of description, if the words "upper", "lower", "left" and "right" appear in the following, they only indicate that the upper, lower, left and right directions are consistent with the drawings themselves, and do not limit the structure.

[0020] like Figure 1 As shown, a partition wall for a rail vehicle provided in this embodiment includes a left partition 1, a right partition 4, a top slide 2, a sliding door 3, a bottom slide 6, a first frame 9 and a limit seat 7.

[0021] A door opening is formed between the left partition 1 and the right partition 4. The top chute 2 is connected to the top of the left partition 1 and the right partition 4, and the bottom chute 6 is connected to the bottom of the left partition 1 and the right partition 4.

[0022] like Figure 2 As shown, the bottom slide groove 6 includes a horizontal side and a vertical side that are perpendicular to each other, the horizontal side is connected to the left partition 1 and the right partition 4, and the vertical side extends upward.

[0023] The top of the sliding door 3 is slidably connected to the top slide 2 through a hanging wheel assembly 11, and the bottom of the sliding door 3 is slidably connected to the bottom slide 6 through a first pulley 8. The first frame 9 has two openings that are arranged opposite to each other, and the openings make the first frame 9 form an H shape. The interior of the opening forms a cavity. One of the openings faces downward, and the vertical edge of the bottom slide 6 extends into the opening. A sealing strip 15 is provided on the side wall of the vertical edge, and the sealing strip 15 contacts the side surface of the vertical edge to achieve sealing. At the same time, the first pulley 8 is rotatably installed in the downward opening, and the outer cylindrical surface of the first pulley 8 is in end-face contact with the top surface of the vertical edge, so that the first frame 9 can slide along the bottom slide 6 through the first pulley 8.

[0024] The sliding door 3 forms a first position when it slides toward the right partition 4, and forms a second position when it slides toward the door opening. When the sliding door 3 is in the first position, the door opening is open; when the sliding door 3 is in the second position, the door opening is closed.

[0025] A rubber strip 10 is disposed in the upward opening of the first frame 9. Figure 1 , Figure 2 As shown, the sliding door 3 is formed by two overlapping door glasses 14, and glue is applied between the two door glasses 14. A door lock 5 is provided on the sliding door 3, and the door lock 5 is installed at the corresponding positions of the sliding door 3 and the left partition 1. At the same time, by adding and adjusting the thickness of the rubber gasket, the lock body and the lock box are made to be consistent in height, so that the lock body can smoothly enter the lock box. The door lock 5 is used to achieve locking when the sliding door 3 is closed.

[0026] The bottom of the sliding door 3 is installed inside the upward opening of the first frame 9 through the rubber strip 10. A decorative strip (not numbered) is arranged outside the bottom slide 6 and the first frame 9, which can prevent dust and collision on the one hand, and ensure aesthetics on the other hand.

[0027] like Figure 3 As shown, the top slide 2 includes an outer frame 21 and an inner plate 22. A downwardly opening slide groove 23 is provided in the outer frame 21, and the outer frame 21 forms an "h" shape. A first rib plate 19 and a second rib plate 12 are protruded from two opposite side walls of the outer frame 21 forming the slide groove 23. The first rib plate 19 is arranged at the bottom of the outer frame 21, and the second rib plate 12 is arranged above the first rib plate 19.

[0028] The first rib plate 19 includes a horizontal first wall 191 and a second wall 192 extending vertically upward from the end of the horizontally extending first wall 191. The end of the second wall 192 is provided with a rounded corner.

[0029] The second rib plate 12 is a horizontally extending plate-shaped structure. A first installation cavity is formed between the second rib plate 12 and the first rib plate 19 , and a second installation cavity is formed between the second rib plate 12 and the bottom of the sliding groove 23 .

[0030] The outer frame 21 is mounted on a side wall of the inner plate 22, and a mounting groove 24 is formed between the inner plate 22 and the outer frame 21. The length of the outer frame 21 matches the distance between the first position and the second position. That is, the length of the outer frame 21 is related to the sliding stroke of the sliding door 3. After installation, the outer frame 21 and the door lock 5 are located on the same side.

[0031] The top of the right partition 4 is embedded in the installation groove 24 , and the hanging wheel assembly 11 is slidably disposed in the sliding groove 23 .

[0032] The hanging wheel assembly 11 includes a second frame 16, a connecting rod 17 and a second pulley 18. The bottom of the second frame 16 is installed with the top of the sliding door 3. One end of the connecting rod 17 extends from the top of the second frame 16 and is installed. The other end of the connecting rod 17 extends into the sliding groove 23 and is connected to the second pulley 18. The second pulley 18 is arranged in the first installation cavity. The connecting rod 17 can be a screw. One second pulley 18 is arranged on each side of the connecting rod 17, and the two second pulleys 18 are respectively slidably connected with the corresponding second wall 192. In the selection of the second pulley 18, a structure with a concave middle portion can be selected so that the concave structure can contact the second wall 192.

[0033] A damper 13 is arranged in the second installation cavity, and the damper 13 is connected to the connecting rod 17. During installation, a proper amount of lubricant can be added into the top slide groove 2, and then the damper 13 can be installed.

[0034] like Figure 1 As shown, two limit seats 7 are installed on the bottom slide groove 6, one of which is used to limit the position of the sliding door 3 when it is in the first position, and the other limit seat 7 is used to limit the position of the sliding door 3 when it is in the second position. Baffles can be provided at both ends of the outer frame 21, and the baffles are used to set the sliding door 3 at two extreme positions, and limit the position together with the limit seats 7.

[0035] The damper 13, the limit seat 7 and the door lock 5 are used in combination to effectively prevent the door glass 14 from cracking due to impact during sliding.

[0036] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
