[0036] shown, includes a bracket, a motor 101, a gear 102, a rack 103, a hook 104 and a torsion spring 105;

[0037] A through rack movement cavity 106 is provided inside the bracket. The motor 101 is fixedly assembled on the bracket and its output shaft is connected to the gear 102. The rack 103 is slidably assembled in the rack movement cavity 106 and meshes with the gear 102. The hook 104 is assembled at the front end of the rack 103 through the torsion spring 105;

[0038] The motor 101 drives the gear 102 to rotate, driving the rack 103 to reciprocate back and forth in the rack movement cavity 106, driving the hook 104 to push and pull the access box 2; a driving inclined surface 107 is provided at the bottom of the inner end of the hook 104. When the hook 104 reciprocates back and forth, the torsion spring 105 drives the hook 104 to rotate downward to hook the access box 2; when the hook 104 resets, the front end of the bracket abuts against the driving inclined surface 107 and drives the hook 104 to rotate upward to disengage from the access box 2 through the driving inclined surface 107.In this embodiment, the bracket is used to support the motor 101 and the rack 103. The motor 101 is a reduction motor, which is used to drive the gear 102 and the rack 103 to move, so that the rack 103 reciprocates back and forth, driving the hook 104 to reciprocate back and forth, and pushing and pulling the access box 2 for access. The torsion spring 105 is used to drive the hook 104 to rotate downward to hook the access box 2, so as to facilitate the pushing and pulling of the access box 2. The rack moving cavity 106 is used to limit the reciprocating movement of the rack 103 back and forth. The driving inclined surface 107 is used to drive the hook 104 to rotate upward to disengage from the access box 2. When the rack 103 moves backward and the front end of the bracket abuts against the driving inclined surface 107, and then continues to drive the hook 104 to move backward. Under the action of the driving inclined surface 107, the front end of the bracket will drive the hook 104 to rotate upward to disengage from the access box 2.

[0039] In this embodiment, the connection mode between the hook 104 and the access box 2 is a movable detachable connection. When the hook 104 hooks the access box 2, the hook 104 can drive the access box 2 to reciprocate back and forth, push the access box 2 out of the access management cabinet to take out the items inside, or pull the access box 2 into the access management cabinet to store the items inside. When the hook 104 resets and disengages from the access box 2, then move the next access box 2 to the front end of the hook 104. The hook 104 moves forward again, the driving inclined surface 107 disengages from the front end of the bracket, and the hook 104 rotates downward under the action of the torsion spring to hook the access box 2, and then access the next access box 2.

[0040] Embodiment 2

[0041] This embodiment is further elaborated on the basis of Embodiment 1, as Figure 3 and Figure 5 shown, a front positioning switch 108 and a rear positioning switch 109 for positioning the reciprocating movement of the rack 103 back and forth are assembled on the bracket. Both the front positioning switch 108 and the rear positioning switch 109 are electrically connected to the control board 110, and the control board 110 is electrically connected to the motor 101. The front positioning switch 108 and the rear positioning switch 109 send the positioning detection information to the control board 110, and the control board 110 then controls the motor 101 to stop running.

[0042] As Figure 3 and Figure 5 shown, positioning touch plates 111 are provided on both the front positioning switch 108 and the rear positioning switch 109, and a rear stop piece 112 is provided at the rear end of the rack 103;

[0043] As Figure 1 shown, the rack 103 moves backward under the drive of the motor 101. When it moves to the end, the hook 104 rotates upward and contacts the positioning touch plate 111 of the front positioning switch 108, and sends the contact signal to the control board 110. The control board 110 controls the motor 101 to stop rotating, and the rack 103 moves backward in place.

[0044] As Figure 2 shown, the rack 103 moves forward driven by the motor 101. After moving to the end, the baffle 112 contacts the positioning plate 111 of the rear positioning switch 109, and sends the contact signal to the control board 110. The control board 110 controls the motor 101 to stop rotating, and the rack 103 moves forward in place.

[0045] Embodiment 3

[0046] This embodiment is further elaborated on the basis of Embodiment 2. As Figure 3 、 Figure 4 Figure 5 shown, the bracket includes a horizontal plate 113, a vertical plate 114 and a rack assembly plate 115;

[0047] The horizontal plate 113 is fixedly installed on the fixed shaft of the access management cabinet through bolts. The vertical plate 114 is assembled on the horizontal plate 113, and the rack assembly plate 115 is assembled at the front end of the vertical plate 114. A rack movement cavity 106 is horizontally arranged in the rack assembly plate 115.

[0048] As Figure 5 shown, a U-shaped notch is provided on the rack assembly plate 115. The U-shaped notch exposes the rack 103 in the rack movement cavity 106. The gear 102 meshes with the rack 103 at the U-shaped notch to make the transmission stable and prevent the rack 103 from shaking during transmission.

[0049] As Figure 5 shown, a rack spring piece 116 is provided at the front end of the bracket. Before the rack 103 moves backward in place, the rear end of the hook 104 abuts against the front end of the rack spring piece 116. Before the rack 103 moves forward in place, the front end of the rear baffle 112 abuts against the rear end of the rack spring piece 116. The rack spring piece 116 plays a role in shock absorption and positioning. When the manipulator is in place, it contacts the side of the hook 104 or the rear baffle 112, which plays a role in decelerating and limits the movement of the rack 103.

[0050] As Figure 3 shown, a number of bolt holes are provided on the horizontal plate 113. The position of the horizontal plate 113 on the fixed shaft of the access management cabinet can be adjusted by using the bolt holes, so as to install the rack transmission manipulator at a suitable position on the fixed shaft.

[0051] As Figure 1 and 2 shown, a hook groove 21 adapted to the hook 104 is provided on the rear side wall of the access box 2, so as to be hooked by the hook 104 for pushing and pulling.

[0052] As Figure 1As shown in the figure, the upper and lower ends of the access box 2 are slidably assembled on the slide rail 3 so that the access box 2 can be pushed and pulled in and out of the access management cabinet when being pushed and pulled.

[0053] For a better understanding of the present utility model, the working principle of the present utility model will be described completely as follows:

[0054] The extending movement of the manipulator: In the reset state of the manipulator, as Figure 1 shown in the figure, after the control board 110 issues a movement signal, the reduction motor 101 rotates forward, driving the gear 102 to move. The gear 102 meshes with the rack 103 and moves forward, pushing out the hook 104. Under the action of the torsion spring 105, the hook 104 opens downward and hooks the access box 2 to drive the access box 2 to move forward and be pushed out. As Figure 2 shown in the figure, when the rack 103 moves to the position where the rear baffle 112 touches the positioning plate 111 of the rear positioning switch 109, the rear positioning switch 109 feeds back a signal to the control board 110, and the control board 110 shuts down the reduction motor 101. The reduction motor 101 stops moving, and the hook 104 pushes the access box 2 to the pushing-out position. Then the staff can take out the items in the access box 2.

[0055] The retracting movement of the manipulator: In the extended state of the manipulator, as Figure 2 shown in the figure, after the control board 110 issues a movement signal, the reduction motor 101 rotates in reverse, driving the gear 102 to move. The gear 102 meshes with the rack 103 and moves backward. The hook 104 at the front end of the rack 103 hooks the access box 2 to drive the access box 2 into the access management cabinet. When the hook 104 touches the positioning plate 111 of the front positioning switch 108, the front positioning switch 108 feeds back a signal to the control board 110, shuts down the reduction motor 101, and the reduction motor 101 stops moving. The hook 104 drives the access box 2 to the storage position.

[0056] Meanwhile, when the rack 103 moves backward and the front end of the bracket abuts against the driving inclined surface 107, it continues to drive the hook 104 to move backward. Under the action of the driving inclined surface 107, the front end of the bracket will drive the hook 104 to rotate upward and disengage from the access box 2, as Figure 1 shown in the figure. After the hook 104 resets and disengages from the access box 2, move the next access box 2 to the front end of the hook 104. Then the hook 104 moves forward, the driving inclined surface 107 disengages from the front end of the bracket, and the hook 104 rotates downward under the action of the torsion spring and hooks the access box 2 to perform the access operation on the next access box 2.

[0057] The above has specifically described the embodiments of the present utility model, but the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent variations or substitutions without departing from the spirit of the present utility model, and these equivalents or substitutions are all included within the scope defined by the claims of the present utility model.
