[0038] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the emergency stop mechanism 6 includes a pulling rod 61, a pull rope 62, an emergency stop spring 63, a sliding plate 64 and a pin 65, the sliding plate 64 is movably connected to the upper part of the hand lever 5, the left side of the sliding plate 64 is connected with four pins 65 in the circumferential direction, the four pins 65 are inserted into the upper second transmission wheel of the second transmission group 31, the pin 65 can limit the upper second transmission wheel of the second transmission group 31, the emergency stop spring 63 is connected between the right side of the sliding plate 64 and the right inner wall of the dense shelf body 4, the emergency stop spring 63 is wound around the hand lever 5, the right upper part of the hand lever 5 is slidably connected with the pulling rod 61, the upper part of the pulling rod 61 is connected with the pull rope 62, the pull rope 62 passes through the hand lever 5 from front to back, and the pull rope 62 is connected with the right side of the sliding plate 64, the pull rope 62 and the hand lever 5 are slidably connected.
[0039] As shown in Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the stabilizing mechanism 7 comprises stabilizing frames 71, first compression springs 72, second compression springs 73, friction blocks 74, pressing plates 75 and third compression springs 76. Each of the left and right sides of the moving piece 1 is slidably connected with a set of stabilizing frames 71. Each set of stabilizing frames 71 comprises four stabilizing frames 71, which are symmetrically arranged front-to-back and left-to-right. The first compression spring 72 is fixed between each of the left and right sides of each stabilizing frame 71 and the lower side of the moving piece 1. The first compression spring 72 is wound around the upper portion of the stabilizing frame 71. Three third compression springs 76 are connected to the middle of the bottom of each stabilizing frame 71. The three third compression springs 76 are symmetrically arranged front-to-back. The pressing plate 75 is connected between the lower sides of the three third compression springs 76 of the bottom of each stabilizing frame 71. The pressing plate 75 is located above the moving rail 2. The second compression spring 73 is connected to the left and right inner walls of the lower portion of each stabilizing frame 71. The friction block 74 is welded to the side of each of the two second compression springs 73 of each stabilizing frame 71. The pressing plate 75 is clamped between the two adjacent friction blocks 74. The pressing plate 75 can limit the friction blocks 74.
[0040] At the beginning, the friction block 74 is extruded by the pressing plate 75, and the second compression spring 73 is in the compressed state. In use, first pull down the pull rod 61. The downward movement of the pull rod 61 pulls the right end of the pull rope 62 downward, and the left end of the pull rope 62 moves rightward, thereby driving the sliding plate 64 and the catch pin 65 to move rightward, and the catch pin 65 is disengaged from the upper side transmission wheel in the second transmission set 31. Then, the hand crank 5 can be rotated. The rotation of the hand crank 5 drives the second transmission set 31 to transmit, and the second transmission set 31 drives the pulley shaft of the moving part 1 to rotate, and drives the first transmission set 3 to transmit. At this time, the moving part 1 will drive the compact shelf body 4, the stabilizing frame 71 and the friction block 74 to move forward along the moving rail 2, so that the compact shelf body 4 can be opened. Then, people can store files in the compact shelf body 4. In the process of moving the moving part 1, because the center of gravity of the compact shelf body 4 is high, the contact area between the moving part 1 and the moving rail 2 is small, and the moving part 1 is prone to tilting. When the moving part 1 tilts, the stabilizing frame 71 and the pressing plate 75 move downward and close to the moving rail 2. The first compression spring 72 deforms adaptively. Thus, the moving part 1 can be buffered. When the pressing plate 75 moves to the side close to the moving rail 2 and contacts the moving rail 2, the pressing plate 75 moves upward and separates from the friction block 74 under the extrusion of the moving rail 2. The third compression spring 76 is compressed. At this time, under the elastic action of the second compression spring 73, the friction blocks 74 on the same stabilizing frame 71 move to the side close to each other, and the friction blocks 74 contact the moving rail 2. At this time, the forward movement of the friction blocks 74 will generate friction with the moving rail 2. Thus, the speed of the forward movement of the friction blocks 74, the stabilizing frame 71 and the moving part 1 can be slowed down, so as to avoid the moving part 1 and the compact shelf body 4 from tilting and falling and pressing the worker. When the moving part 1 returns to the normal position, the third compression spring 76 rebounds and moves the pressing plate 75 downward. The pressing plate 75 moves the friction blocks 74 outward, so that the friction blocks 74 are separated from the moving rail 2. The second compression spring 73 is compressed. When the moving part 1 drives the compact shelf body 4 to move forward, if an obstacle is found in front of the compact shelf body 4, the compact shelf body 4 needs to be stopped urgently. Then, the pull rod 61 is released, the pull rope 62 is released, the emergency stop spring 63 rebounds and moves the sliding plate 64 and the catch pin 65 leftward. The catch pin 65 is clamped into the upper side second transmission wheel in the second transmission set 31. Thus, the upper side second transmission wheel in the second transmission set 31 can be limited, and the second transmission set 31 cannot transmit. At this time, the moving part 1 and the compact shelf body 4 also stop moving forward, so as to achieve the effect of stopping the moving part 1 and the compact shelf urgently. When the compact shelf body 4 needs to be closed, the upper side second transmission wheel in the second transmission set 31 is unlocked, and then the hand crank 5 is reversely rotated. The reverse rotation of the hand crank 5 drives the second transmission set 31 and the first transmission set 3 to reversely transmit, so that the moving part 1 and the compact shelf body 4 move backward and reset. Thus, the compact shelf can be closed.

[0046] The stable frame 71 moves forward to drive the sliding rod 92 and the deceleration block 91 to move forward, when the deceleration block 91 moves forward and contacts the front wall in the moving rail 2, the deceleration block 91 is pressed backward, the deceleration block 91 moves backward to drive the sliding rod 92 to move backward to extend into the stable frame 71, the deceleration spring 93 is compressed, and the backward movement of the deceleration block 91 also drives the pressing plate 75 to move upward, so that when the dense shelf moves to the edge, the movement speed of the dense shelf is slowed down, the dense shelf is prevented from falling due to too fast movement, and the stability of the dense shelf is enhanced, when the stable frame 71 drives the sliding rod 92 and the deceleration block 91 to move back to reset, the deceleration block 91 and the front wall in the moving rail 2 are separated, the deceleration spring 93 rebounds to drive the deceleration block 91 and the sliding rod 92 to move forward, and the sliding rod 92 extends out of the stable frame 71.
