DETAILED DESCRIPTION

[0033] The present invention is further described below in conjunction with specific embodiments. It should also be noted that, unless otherwise clearly specified and limited, terms such as: setting, installing, connecting, and connecting should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] Example 1

[0035] A compact rack for storing physical evidence, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a base 1, a compact shelving unit 2, a door panel 3 and a moving mechanism 4. Four compact shelving units 2 are slidably connected to the base 1 from front to back. The compact shelving units 2 are divided into four layers. The frontmost compact shelving unit 2 is rotatably connected to the door panel 3 on both sides. A moving mechanism 4 is provided on the right side of the base 1. The moving mechanism 4 can drive the designated compact shelving unit 2 to move.

[0036] like Figure 1 , Figure 4 and Figure 5 As shown, the moving mechanism 4 includes a motor 41, a first screw rod 42, a driving ring 43, a fixed seat 44, a clamping plate 45, a second screw rod 46 and a rotating wheel 47. There are four fixed seats 44, which are respectively welded to the right side of the lower part of the dense rack 2. There are four clamping plates 45, which are respectively slidably connected to the rear of the fixed seat 44. The clamping plates 45 are all threadedly connected with the second screw rod 46. The front of the second screw rod 46 is rotatably connected to the fixed seat 44. The rear side of the second screw rod 46 is connected with a rotating wheel 47. The motor 41 is bolted to the upper right rear side of the base 1. The first screw rod 42 is connected to the output shaft of the motor 41 through a coupling. The first screw rod 42 is rotatably connected to the right front part of the base 1. Four driving rings 43 are threadedly connected to the first screw rod 42 from front to back. The driving rings 43 are all located between adjacent fixed seats 44 and clamping plates 45, and the driving rings 43 are all in contact with the fixed seats 44.

[0037] like Figure 2 , Figure 6 and Figure 7 As shown, it also includes an anti-drop mechanism 5, which includes an anti-drop frame 51 and a torsion spring 52. The compact shelving 2 is rotatably connected with three anti-drop frames 51 in sequence from top to bottom. The anti-drop frames 51 can resist the physical evidence in the compact shelving 2 to prevent the physical evidence from falling out of the compact shelving 2. Torsion springs 52 are connected between the left and right sides of the anti-drop frame 51 and the inner wall of the compact shelving 2, and the torsion springs 52 are all wound on the anti-drop frame 51.

[0038] like Figure 6 As shown, a handle 53 is also included. The upper and middle parts of the anti-drop frame 51 are connected with the handle 53. The handle 53 is convenient for people to rotate the anti-drop frame 51.

[0039] Initially, evidence has been stored in the compact rack 2. When people need to take out evidence in the designated compact rack 2, they need to move the compact rack 2 in front of the designated compact rack 2 forward, unfold the designated compact rack 2, rotate the second screw rod 46 clockwise through the rotating wheel 47, and the second screw rod 46 rotates clockwise to drive the clamping plate 45 to move forward to clamp the driving ring 43, and then turn on the motor 41, so that the output shaft of the motor 41 drives the first screw rod 42 to rotate clockwise, and then the driving ring 43 drives the fixing seat 44, the clamping plate 45 and The compact shelving 2 moves forward, so that the corresponding compact shelving 2 can be moved forward, so as to achieve the effect of unfolding the designated compact shelving 2. When the compact shelving 2 is unfolded, the compact shelving 2 may shake. At this time, the anti-drop frame 51 will resist the evidence in the compact shelving 2, thereby preventing the evidence in the compact shelving 2 from falling out and protecting the evidence. When people need to take out the evidence, the anti-drop frame 51 is rotated forward 90 degrees through the handle 53, so that the anti-drop frame 51 is in a parallel state, the torsion spring 52 is twisted, and then the evidence can be found. When people store physical evidence, the physical evidence may be located relatively forward, and the front part of the physical evidence is suspended on the compact rack 2, so the physical evidence is easy to fall forward. After people release the anti-drop frame 51, the anti-drop frame 51 is quickly reversed and reset by the torsion spring 52. At the moment when the anti-drop frame 51 is reset, the anti-drop frame 51 will push the physical evidence backward, thereby protecting the physical evidence. Then, the output shaft of the control motor 41 drives the first screw rod 42 to rotate counterclockwise, and the first screw rod 42 rotates counterclockwise to drive the driving ring 43 to drive the fixing seat 44 and the clamping plate 45. The compact shelving 2 moves backwards so that the compact shelving 2 is closed, and then the second screw rod 46 is rotated counterclockwise by the rotating wheel 47. The second screw rod 46 rotates counterclockwise to drive the clamping plate 45 to move backwards away from the driving ring 43. The above operations can be repeated to unfold the specified compact shelving 2 without fully unfolding the compact shelving 2, thereby occupying a small area and saving space. The anti-drop rack 51 can resist the physical evidence in the compact shelving 2 to prevent the physical evidence in the compact shelving 2 from falling out, thereby protecting the physical evidence and preventing the physical evidence from being damaged.

[0040] Example 2

[0041] On the basis of Example 1, Figure 1 and Figure 8As shown, a buffer mechanism 6 is also included, and the buffer mechanism 6 includes a buffer plate 61, a buffer frame 62, a first linear spring 63 and a fixed plate 64. There are three buffer plates 61, and the three buffer plates 61 are respectively fixed to the right side of the front of the three dense shelves 2 on the rear side. The right side of the rear of the three dense shelves 2 on the front side is connected with a fixed plate 64, and the fixed plate 64 is slidably connected with a buffer frame 62. The rear side of the buffer frame 62 is fitted with the front side of the buffer plate 61, and the first linear springs 63 are connected between the upper and lower sides of the buffer frame 62 and the adjacent fixed plates 64. The first linear springs 63 are all wound on the buffer frame 62, and the dense shelves 2 are buffered by the cooperation between the buffer plate 61, the buffer frame 62 and the first linear spring 63.

[0042] When the compact shelving 2 is closed, in order to avoid collision between the two compact shelving 2, a buffer mechanism 6 can be used to buffer the compact shelving 2. Initially, the buffer plate 61 squeezes the buffer frame 62 forward, and the first linear spring 63 is in a compressed state. When the compact shelving 2 is unfolded, the compact shelving 2 drives the fixed plate 64, the buffer frame 62 and the first linear spring 63 to move forward. When the buffer frame 62 moves away from the buffer plate 61, the first linear spring 63 rebounds and drives the buffer frame 62 to slide backward on the fixed plate 64. When the compact shelving 2 is closed and moves backward, the compact shelving 2 will also drive The fixed plate 64, the buffer frame 62 and the first linear spring 63 move backward. When the buffer frame 62 moves backward and contacts the buffer plate 61, the buffer plate 61 squeezes the buffer frame 62 forward and the first linear spring 63 is compressed. At this time, the first linear spring 63 will buffer the buffer frame 62 to reduce the backward impact force of the buffer frame 62. In this way, the dense shelving 2 can be buffered through the cooperation between the buffer plate 61, the buffer frame 62, the first linear spring 63 and the fixed plate 64 to avoid collision between the dense shelving 2 and thereby prevent the dense shelving 2 from shaking violently.

[0043] like Figure 2 and Fig. 9 As shown, it also includes a locking mechanism 7, which includes a locking frame 71, a second linear spring 72 and a limit block 73. Three locking frames 71 are slidably connected to the left and right sides of the compact shelving 2 in sequence from top to bottom. The locking frames 71 can limit the anti-drop frame 51 in a horizontal state. Every two parallel locking frames 71 correspond to an anti-drop frame 51. A second linear spring 72 is connected between the rear side of the locking frame 71 and the inner wall of the compact shelving 2. Three limit blocks 73 are connected to the left and right sides of the compact shelving 2 in sequence from top to bottom. The limit blocks 73 are all located in the front middle of the locking frame 71.

[0044] When the locking yoke 72 is in the unlocked position, the locking yoke 72 will be in the unlocked position, and the locking yoke 72 will be in the unlocked position when the locking yoke 51 is unlocked. People need to hold the anti-drop frame 51 with their hands all the time, so that it is convenient for people to find physical evidence, and the anti-drop frame 51 after limiting can be used as a desktop for people to view physical evidence, so that it is convenient for people to flip through and view the physical evidence. When the physical evidence is taken out, the positioning frame 71 is moved backward, and the second linear spring 72 is compressed. At this time, the positioning frame 71 no longer limits the anti-drop frame 51, and the anti-drop frame 51 will automatically rotate backward and reset. Repeat the above operation to use the positioning frame 71 to limit the anti-drop frame 51 rotated to a horizontal state, which is convenient for people to take physical evidence.

[0045] like Figure 2 , Fig.10 and Fig.11 As shown, it also includes a lighting mechanism 8, which includes a slide rail 81, a first sliding plate 82, a second sliding plate 83 and a lighting lamp 84. Three slide rails 81 are sequentially connected to the left and right sides of the inner wall of the compact shelving 2 from top to bottom, and a first sliding plate 82 is slidably connected between two parallel aligned slide rails 81. A second sliding plate 83 is slidably connected to the first sliding plate 82, and a lighting lamp 84 is connected to the front side of the second sliding plate 83. When the lighting lamp 84 is turned on, it can illuminate the interior of the compact shelving 2, making it easier for people to find physical evidence.

[0046] When people take physical evidence at night, they can illuminate the inside of the compact shelving 2 through the lighting mechanism 8. First, turn on the lighting lamp 84 to illuminate the inside of the compact shelving 2, and adjust the left and right position of the lighting lamp 84 by moving the second sliding plate 83 left and right. The front and back positions of the lighting lamp 84 can be adjusted by moving the first sliding plate 82 and the second sliding plate 83 forward and backward, thereby achieving the effect of adjusting the front, back, left and right positions of the lighting lamp 84. In this way, the position of the lighting lamp 84 can be adjusted, which is beneficial for people to find physical evidence.

[0047] like Figure 2 , Fig.12 and Fig.13 As shown, it also includes a pulling mechanism 9, which includes a rotating lever 91 and a movable frame 92. The rotating lever 91 is connected to the left and right sides of the rear of the anti-drop frame 51, and the movable frames 92 are connected to the left and right sides of the bottom of the first sliding plate 82. The movable frames 92 are slidably connected to the slide rails 81, and the lower part of the movable frames 92 is movably connected to the rear of the rotating lever 91.

[0048] When the anti-fall frame 51 rotates forward and drives the rotating lever 91 to move forward, the rotating lever 91 will drive the first sliding plate 82, the second sliding plate 83 and the lighting lamp 84 to move forward through the moving frame 92. Then, when people flip through the evidence on the horizontal anti-fall frame 51, the lighting lamp 84 can illuminate the area on the anti-fall frame 51, making it easier for people to check the evidence placed on the anti-fall frame 51. When the anti-fall frame 51 rotates backward and drives the rotating lever 91 to move backward, the rotating lever 91 will drive the first sliding plate 82, the second sliding plate 83 and the lighting lamp 84 to move backward through the moving frame 92.

[0049] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
