DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1:

[0025] Furthermore, the supporting structure includes a shelf column 202, which is slidably installed inside the adjustment seat 201. A base 203 is installed at one end of the shelf column 202, and a socket 204 is provided inside the base 203. The shelf column 202 is adapted to the socket 204, and the same shelves can be stacked up and down. The socket 204 on the base 203 of the upper shelf is placed on the shelf column 202 of the lower shelf for positioning, and then it can be fixed by welding or bolts.

[0026] Furthermore, the limiting structure includes two clamping plates 301, which are slidably installed on both sides of the adjustment seat 201 respectively, and the two clamping plates 301 are rotatably installed on one end of the two adjusting screw rods 300 respectively. A clamping slot 302 is provided on one side of the two clamping plates 301, and the beam frame 100 is located in the two clamping slots 302. When the adjusting screw rod 300 rotates, it can move inside the adjusting seat 201 by cooperating with the thread of the adjusting seat 201, so that the moving adjusting screw rod 300 can drive the clamping plate 301 to move, so that the clamping plate 301 can drive the clamping slot 302 to disengage from the side of the beam frame 100. When the clamping plate 301 is completely away from the beam frame 100, the angle limit between the adjusting seat 201 and the beam frame 100 can be released.

[0027] Furthermore, a T-shaped limit groove 303 is opened inside the card plate 301, and a T-shaped bar 304 is slidably installed in the T-shaped limit groove 303. The T-shaped bar 304 is installed on one side of the adjustment seat 201. When the card plate 301 moves, it can slide on the T-shaped bar 304 through the T-shaped limit groove 303, thereby limiting the direction of movement of the card plate 301 and avoiding deviation.

[0028] Furthermore, two limiting rings 305 are fixedly provided on the adjusting screw rod 300, and the two limiting rings 305 are rotatably installed on one side of the card plate 301 and the inside of the card plate 301 respectively. When the adjusting screw rod 300 rotates, it can drive the two limiting rings 305 to rotate on one side of the card plate 301 and the inside of the card plate 301 respectively. Through the setting of the two limiting rings 305, the adjusting screw rod 300 can be prevented from loosening from the card plate 301.

[0029] Example 2:

[0030] like Figure 1-5In order to facilitate further adjustment of the support height and the occupied area after folding, an adjustment structure is arranged on the fixed screw 400, wherein the adjustment structure includes a threaded sleeve 401, the threaded sleeve 401 is threadedly sleeved on the fixed screw 400, and the two ends of the fixed screw 400 are respectively mounted on the base 203 and the shelf column 202, and the fixed screw 400 is rotatably mounted inside the adjustment seat 201, and both ends of the threaded sleeve 401 are installed with limit rings 405, and the two limit rings 405 are rotatably mounted on the inner walls of both sides of the adjustment seat 201, and a U-shaped frame 402 is installed on one side of the adjustment seat 201, and a positioning screw 403 is installed on the internal thread of the U-shaped frame 402. 1 is provided with two positioning holes 404, and one end of the positioning screw 403 is movably installed in the corresponding positioning hole 404. By rotating the positioning screw 403 and unscrewing it from the positioning hole 404, the restriction of the threaded sleeve 401 can be released. At this time, rotating the threaded sleeve 401 can drive the adjustment seat 201 to move on the shelf column 202, and then drive the crossbeam frame 100 to move vertically through the clamping plate 301, so as to adjust the distance between the upper and lower crossbeam frames 100 and the support height of the crossbeam frame 100. After the shelf is folded, the shelf columns 202 on both sides can be adjusted inward by rotating the threaded sleeves 401 on both sides, thereby further reducing the occupied space. The other features are the same as those in Example 1.

[0031] Working principle: When you need to fold the shelf, you can refer to Figure 1 The adjusting screw rods 300 at the four corners of the shelves can be rotated after the upper and lower shelves are separated. The rotating adjusting screw rods 300 will drive the two limiting rings 305 to rotate on one side of the card plate 301 and inside the card plate 301 respectively. When the adjusting screw rods 300 rotate, they can move inside the adjusting seat 201 by cooperating with the threads of the adjusting seat 201, thereby making the movable adjusting screw rods 300 able to drive the card plate 301 to move through the cooperation of the two limiting rings 305, so that the card plate 301 passes through the T-shaped limit slot 3 03 Slide on the T-bar 304. When the card plate 301 moves, it can drive the card slot 302 to detach from the side of the beam frame 100. When the card plate 301 is completely away from the beam frame 100, the angle limit between the adjustment seat 201 and the beam frame 100 can be released. At this time, the shelf column 202 can be turned over to drive the adjustment seat 201 to rotate. The adjustment seat 201 can drive the rotating rod 200 to rotate inside the beam frame 100. The rotating rod 200 can be used as the rotation fulcrum of the adjustment seat 201, and the shelf column 202 can be turned 90 degrees to make it present Figure 2The reset cards 301 can block the upper and lower sides of the crossbeam frame 100, so that the angle between the shelf columns 202 and the crossbeam frame 100 can be re-restricted. The blocked shelves can be stacked on each other to reduce the space occupied by transportation. By limiting the angle between the crossbeam frame 100 and the shelf columns 202, movement during transportation can be avoided. Conversely, the shelves can be unfolded by reversing the above steps. The same shelves can be stacked up and down, and the sockets 204 on the upper shelf base 203 can be put on the shelf columns 202 of the lower shelf for positioning, and then they can be fixed by welding or bolts.

[0032] exist Figure 1 The screw threaded sleeve 401 is fixed to the shelf column 202, and the fixing screw 400 is fixed to the shelf column 202, so that the fixing screw 400 can be fixed to the shelf column 202, and the fixing screw 400 can be ... and the fixing screw 400 can be fixed to the shelf column 202, so that the fixing screw 400 can be fixed to the shelf column 202, and the fixing screw 400 can be fixed to the shelf column 202, and Figure 2 In this state, the shelf columns 202 on both sides can be adjusted inward by rotating the threaded sleeves 401 on both sides to further reduce the space occupied. After adjustment, the positioning screws 403 can be screwed back into the corresponding positioning holes 404 to fix the angles of the threaded sleeves 401 to prevent the shelf columns 202 from loosening.
