[0039] Among them, the first slide rail seat 101 is a long strip of plate, which can be fixedly installed on the bottom of the vehicle's cabin or the floor of the carriage. The first roller bracket 102 is welded to the upper surface of the first slide rail seat 101, and the first roller 103 is installed on the first roller bracket 102 through the first pin 104. The first roller 103 can rotate around the first pin 104. The two first roller brackets 102 are equipped with four first pins 104 and four first rollers 103.

[0043] Preferably, see Figure 1 , Figure 3 The first mounting plate 106 has a middle platform and shoulders respectively arranged on both sides of the middle platform, the upper surfaces of the two shoulders are flush and lower than the middle platform by a distance. The two shoulders are connected to the middle platform by a vertical side wall respectively. The height difference between the upper surfaces of the two shoulders and the upper surface of the middle platform is suitable for setting the second slide rail seat, the second roller bracket, the second pin shaft and the second roller.

[0044] There are two first slide rails 105, which are respectively arranged on the bottom surface of the first mounting plate 106 and located on the inner sides of the two vertical side walls, and their extension direction is parallel to the length direction of the vertical side surface.

The second rail is arranged at a position matching the second rail seat.

[0046] This arrangement can effectively reduce the height of the double-layer guide rail platform 7, save space, lower the center of gravity, and improve system stability.

[0047] See also Figure 1 , Figure 3 , Figure 4 The manual locking mechanism 3 includes a push-pull rod 301, two mounting brackets 302, a transmission rod 303, a limit block 304, a compression spring 305 and a push-pull rod locking assembly.

[0048] The two mounting supports 302 are both mounted on the back of the second mounting plate 201, wherein the first mounting support is located at the edge of the second mounting plate 201, and its side surface is flush with the side wall of the second mounting plate 201; the second mounting support is adjacent to the edge of the other side of the second mounting plate 201. Through holes are provided on both the first mounting support and the second mounting support. The push-pull rod 301 is rotatably arranged on the first mounting support and is located outside the first mounting support. Its rotation axis passes through the through hole of the first mounting support and is fixedly connected to the transmission rod 303, and can drive the transmission rod 303 to rotate synchronously. The transmission rod 303 passes through the through hole of the second mounting support and is supported by the second mounting support, and can rotate freely relative to the second mounting support. A limit block 304 is fixedly arranged at the end of the transmission rod 303, and one side of the limit block 304 is a "convex" structure, which can be selectively inserted into the grooves of the first limit plate 107 and the second limit plate 108 arranged at both ends of the first slide rail seat 101.

[0049] The other side of the limit block 304 is connected to one end of a compression spring 305, and the other end of the compression spring 305 is fixedly connected to the bottom surface of the second mounting plate 201. The compression spring 305 keeps the limit block 304 in a position where it is inserted into the grooves of the first limit plate 107 and the second limit plate 108, so as to lock the first guide rail platform 1 and the second guide rail platform 2 so that they cannot slide relative to the cabin or the compartment of the vehicle.

[0050] Correspondingly, an opening is provided at a corresponding position of the first mounting plate 106 , so that the limiting block 304 can pass through when it is rotated and inserted into the grooves of the first limiting plate 107 and the second limiting plate 108 .

[0051] See also Figure 4 The push-pull rod 301 is provided with a push-pull rod locking assembly, including a locking tongue 306 , a guide sleeve 307 , a compression spring 308 , a pull rod 309 and a buckle cover 310 .

[0052] A stepped hole is provided near the rotating shaft on the push-pull rod 301, and a compression spring 308, a guide sleeve 307 and a lock tongue 306 are provided in the stepped hole. A buckle cover 310 is fixed on the outer surface of the push-pull rod 301, and the pull rod 309 passes through the buckle cover 310 and is connected with the lock tongue 306. The guide sleeve 307 is provided on the inner side of the stepped hole and sleeved on the pull rod 309. The lock tongue 306 is provided at the end of the pull rod 309. The compression spring 308 is sleeved on the pull rod 309, with one end abutting against the end surface of the buckle cover 310 and the other end abutting against the end surface of the guide sleeve 307. Under the action of the compression spring 308, the lock tongue 306 is kept in the corresponding non-circular hole on the outer surface of the second mounting plate 201, locking the push-pull rod 301 to prevent it from being accidentally touched and causing the first guide rail platform 1 and the second guide rail platform 2 to be unlocked. The non-circular hole can be a triangle, a square, a pentagon, or other shapes that can lock the lock tongue 306, preferably a square hole.

[0053] The pull rod 309 is provided with a "convex" structure, which can interlock with the "concave" structure provided on the buckle cover 310. When the "convex" structure on the pull rod 309 is engaged with the "concave" structure on the buckle cover 310, the rotation of the pull rod 309 relative to the buckle cover 310 can be restricted.

[0054] Through the above arrangement, pulling the pull rod 309 outward can drive the guide sleeve 307 and the lock tongue 306 to move outward together. After the lock tongue 306 moves out of the non-circular hole on the second mounting plate 201, the pull rod 309 is rotated, and the lock tongue 306 rotates accordingly and is stuck outside the non-circular hole. At the same time, the "convex" structure on the pull rod 309 is stuck on the outside of the "concave" structure on the buckle cover 310. At this time, the push-pull rod 301 and the second mounting plate 201 are unlocked, and the push-pull rod 301 can rotate relative to the second mounting plate 201 to unlock the first guide rail platform 1 and the second guide rail platform 2.

[0055] Preferably, two manual locking mechanisms 3 are provided, which are arranged in parallel and spaced apart on the bottom surface of the second mounting plate 201 , and respectively cooperate with a first limiting plate 107 and a second limiting plate 108 on a first slide rail seat 101 .

[0057] The mounting seat 401 is fixed on the lower surface of the second mounting plate 201, and is close to the outer corner. The end of the telescopic rod 402 is hinged to the mounting seat 401 and can rotate around the rotating shaft of the mounting seat 401. The rotating rod 403 is connected to the telescopic rod 402 by a threaded structure. The rotating rod 403 rotates relative to the telescopic rod 402 to change the total length of the folding support rod 4 to adapt to the ground at different heights. A spherical groove is provided on the lower surface of the support plate 405, and a ball joint 404 is fixedly provided at the end of the rotating rod 403, and the ball joint 404 can be inserted into the spherical groove. A buckle 406 is also provided on the lower surface of the second mounting plate 201, and the rotating rod 403 can be fixed to the second mounting plate 201 through the buckle 406 after being folded and contracted.

[0058] Preferably, two folding support rods 4 are provided, which, when opened, support the two corners outside the mouth of the second mounting plate 201, so that the platform is more stable and safety is ensured.
