[0026] The utility model provides a box body locking device, for the purpose, technical scheme and effect of the utility model are more clear, definite, the following is further detailed to the utility model of the utility model.It should be understood that the specific embodiments described here are only to explain the utility model, and are not used to limit the utility model.
[0027] Please refer to Figures 1 to 6 The utility model provides a box body locking device. The drawings are only used for explaining the structure principle and are not proportional to the actual product. The drawings only draw the structure related to the application point of the application, and some conventional structures are not specifically drawn.
[0028] A box body locking device, including motor 2 and bolt 4, spring 6 is sleeved on the bolt, the box body is provided with the insertion hole 90 at the bolt, the main shaft of the motor is provided with cam 3, the cam is opposite to the bolt, the motor can drive the bolt to insert the insertion hole on the box body through the cam.
[0029] It should be noted that the protection scope of the utility model limits the box body, but only limits that the box body is provided with the insertion hole, how the internal structure of the box body is arranged, and the purpose of the box body, which are not limited by the application.
[0030] Further, the bolt 4 is arranged in a bolt seat 5, the bolt seat is provided with a guide hole (the guide hole cannot be observed from the view angle of the drawing), the shape of the guide hole is matched with the shape of the bolt, and the bolt passes through the guide hole. The bolt seat is fixed in the side plate, since the bolt passes through the guide hole of the bolt seat, the guide hole plays a good guiding role in the process that the bolt makes linear reciprocating motion, so that the bolt is smoothly inserted into the insertion hole or withdrawn from the insertion hole.
[0031] The motor driven reciprocating motion of the bolt can have various implementation manners, and the following provides a simple and feasible scheme: as shown in Figure 2 Further, in the box body locking device, the end plate 41 of the bolt 4 towards the motor is provided with an end plate 41, the end plate is opposite to the cam, one end of the spring is opposite to the bolt seat, and the other end of the spring is opposite to the end plate. The motor rotation drives the cam to rotate, since the cam is opposite to the end plate of the bolt, the cam rotation causes the linear reciprocating motion of the bolt. When the bolt moves towards the insertion hole, the spring is compressed to play a certain buffering role; when the cam apex 31 is opposite to the end plate of the bolt, the bolt reaches the farthest end of the stroke (at this time, the bolt is inserted into the insertion hole); after the cam apex leaves the end plate of the bolt, the bolt is withdrawn from the insertion hole under the elastic force of the spring.
[0032] Preferably, the bolt is horizontally arranged, and the main shaft of the motor is vertically arranged (the main shaft of the motor is vertically arranged upwards in the drawing, but can also be vertically arranged downwards, which is not limited here). The arrangement is a relatively optimal choice, which is convenient for the arrangement and assembly of the motor, the bolt, the insertion hole and the like.
[0033] Preferably, the bolt is a circular bolt, the insertion hole arranged on the shell of the box body is a circular hole, and the diameter of the insertion hole is greater than that of the bolt. The arrangement is convenient for the bolt to be smoothly inserted into the insertion hole.
[0034] As shown in Figure 4 and Figure 6As shown, each box body 9 is hinged to the rack of the instrument 1, and the motor, cam and latch are arranged inside the side plate 12 of the rack, opposite to the box body, and the latch can be extended from the through hole 120 on the side plate 12.
[0035] As shown in the drawings, in actual application, two (or more) box bodies 9 can be arranged on one instrument 1, and one motor, cam, latch and the like are arranged in the side plate corresponding to each box body, and the number of box bodies arranged on the rack of the dyeing instrument is not limited.
[0036] The motor is preferably a stepper motor, such as Figure 3 As shown (at this time the latch is not inserted into the insertion hole), when locking is needed, the stepper motor controls the cam to rotate 90 degrees, so that the latch is inserted into the insertion hole in the box body (as shown in Figure 2 The motor is preferably a stepper motor, which can accurately control the rotation of the motor spindle by 90 degrees, thereby ensuring good locking effect. Similarly, after the box body is used, the controller of the instrument sends a command to the motor, and the motor rotates 90 degrees in the opposite direction after receiving the command, and the latch is ejected from the insertion hole, and the box body is unlocked and can be placed flat on the rack. It should be noted that the cam structure shown in the drawings is only one embodiment, and in actual application, the cam can also be arranged in other structures, and the angle of rotation each time for locking or unlocking is not limited to 90 degrees, but can also be other degrees.
[0037] Further, a sensor (not shown in the figure, which can be a Hall sensor or other type of sensor) is arranged below the cam, and the sensor below the cam will reset every time the cam returns to the starting position, avoiding the error accumulation of the stepper motor causing the latch to extend or retract to the specified position, thereby ensuring normal locking or unlocking of the box body.
[0038] It should be noted that the protection scope of the present application is only the box body locking device itself, and the instrument is not limited (for example, it can be a protein dyeing instrument, but is not limited to a protein dyeing instrument), the purpose of the box body, and the mechanism inside the box body are not limited.
[0039] It can be understood that, for those skilled in the art, the technical scheme and the utility model concept of the present application can be replaced or changed equivalently, and all these changes or replacements shall belong to the protection scope of the present application.
