DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3The urban rail passenger car throughway shed connecting mechanism comprises a mounting frame connecting ear 1 and a shed mounting seat 4, a bolt placement groove 5 is provided on the shed mounting seat 4, a connecting bolt 3 is provided in the bolt placement groove 5, a nut 2 is provided on the connecting bolt 3, and a mounting mechanism for mounting the shed is provided on the shed mounting seat 4, the mounting mechanism comprises a rotating rod 9 rotatably connected to the inner wall of the shed mounting seat 4, a square block 8 is fixedly connected to the side wall of the rotating rod 9, a shed connecting plate 7 is provided at the bottom of the shed mounting seat 4, and a square groove 10 capable of cooperating with the square block 8 is provided on the side wall of the shed connecting plate 7, Figure 3 The positional relationship between the mounting frame connecting ear 1, the shelf mounting seat 4, the side panel mounting frame 15, and the shelf body 16 is shown in the figure. The mounting frame connecting ear 1 is fixedly connected to the inner wall of the side panel mounting frame 15, and the shelf connecting plate 7 is fixedly connected to the shelf body 16.

[0022] The side wall of the rotating rod 9 is provided with a limiting mechanism for limiting the position of the square block 8 , and the limiting mechanism includes a baffle 6 rotatably connected to the side wall of the rotating rod 9 , and the baffle 6 is connected to the rotating rod 9 through a torsion spring 14 .

[0023] In the utility model, the side wall of the shelf connecting plate 7 is fixedly connected to a limit rod 11, and a stopper 12 is slidably connected to the limit rod 11, which can limit the horizontal square block 8 so that it does not need human support to maintain the level.

[0024] In the utility model, the cross section of the limit rod 11 is U-shaped to prevent the stop block 12 from falling. The stop block 12 can be moved below the stop block 12 after the square block 8 rotates horizontally. The cross section of the bolt placement groove 5 is T-shaped, so that the umbrella part of the connecting bolt 3 is stuck and cannot rotate.

[0025] In the utility model, the side wall of the shelf connecting plate 7 is fixedly connected with a magnet 13, and the stopper 12 is made of iron, so that the stopper 12 cannot move at will, and the stopper 12 is prevented from shaking and making noise during the movement of the vehicle.

[0026] In the utility model, the cross-section of the shelf mounting seat 4 is L-shaped, so that when the shelf connecting plate 7 is pushed toward the baffle 6, the shelf mounting seat 4 can provide support for it, making the movement more convenient. The rotating rod 9 and the square block 8 are both made of high-strength steel to improve the wear resistance of the equipment.

[0027] In the initial state, a plurality of mounting frame connecting ears 1 are fixedly connected to the inner wall of the side plate mounting frame 15 , and a plurality of shelf plate connecting plates 7 are fixedly connected to the shelf plate body 16 .

[0028] When in use, the shelf body 16 is pushed down the side plate mounting frame 15, the connecting bolts 3 pass through the corresponding mounting frame connecting ears 1, and the nuts 2 are screwed on to fix them. When the shelf body 16 needs to be quickly disassembled, the multiple square blocks 8 can be rotated so that the square blocks 8 are in the same direction as the square grooves 10, and the shelf body 16 can be removed from the multiple shelf mounting seats 4 that have been connected to the mounting frame connecting ears 1. Conversely, after the square blocks 8 are rotated to be in the same direction as the square grooves 10, the multiple shelf connecting plates 7 can be pushed back onto the shelf mounting seats 4, and the square blocks 8 can be rotated vertically to fix the shelf body 16, so that they can be connected without screws, so that the shelf can be quickly disassembled and assembled.
