no. 1 example

[0048] see Figure 1 to Figure 3 , The worm screw self-locking card display seat of the present invention includes a base 1 , the base 1 includes a bottom plate 11 and a side plate 12 , the side plate 12 is provided with a first opening 13 , and the bottom plate 11 is provided with a second opening 14 .

[0049]A self-locking assembly 2 is provided in the base 1, and the self-locking assembly 2 includes a worm 21 and a worm wheel 22 meshed with the worm 21, wherein the lead angle of the worm 21 is smaller than the equivalent friction angle between the teeth of the worm wheel 22. At this time, the self-locking assembly 2. It is self-locking, that is, the worm wheel 22 can only be driven by the worm 21, and the worm 21 cannot be driven by the worm wheel 22. The self-locking property of the self-locking component 2 plays a role of safety protection for the exhibits. The worm 21 includes an operation part 211, wherein the shape of the operation part 211 is the same as that of the ...

[0058] see Figure 4 to Figure 5 , the base 1 is provided with the same component structure as the first embodiment, and a control unit 4 is added in the base 1, the control unit 4 includes a processing module 40, a USB socket 41 and a motor 44, the motor 44 is connected to the worm 21, and the processing module 40 receives After the unlocking signal output by the USB socket 41, a control signal is output to the motor 44, and the motor 44 starts to drive the worm screw 21 to rotate after receiving the control signal.

[0059] The control unit 4 includes a trigger switch 42. When the USB key is lost, the display holder can be manually unlocked and the product removed, and the trigger switch 42 is used to output a trigger signal to the processing module 40. The trigger signal is a password reconfiguration signal, which is convenient for new USB key for password reconfiguration.

[0060] The control unit 4 also includes a Bluetooth module 43, which is used for signal transmissio...

[0086] The control method of the worm screw self-locking card display seat includes the following steps:

[0087] S1. After the processing module 40 receives the unlock signal through the USB socket 41, the processing module 40 outputs a control signal to the motor 44;

[0088] S2, the motor 44 drives the worm screw 21 to rotate according to the control signal;

[0089] S3, the rotation of the worm screw 21 drives the rotation of the worm wheel 22;

[0090] S4, the rotation of the worm wheel 21 drives the rack 31 to move.

[0091] Using this control method, the drive worm 21 can be controlled so that the rotation of the worm 21 is realized under the drive of the motor 44, and the rotation of the worm 21 drives the worm wheel 22 to rotate, thereby driving the rack 31 to move, and the first lock on the rack 31 The distance between the buckle 34 and another buckle is shortened or increased to realize the locking / unlocking of the exhibit, wherein the moving direction of the rack...

Abstract

The invention provides a worm self-locking display base and a control method thereof. The display base comprises a base body, a self-locking assembly in the base body comprises a worm and a worm gear meshed with the worm, and the lead angle of the worm is smaller than the equivalent friction angle between sawteeth of the worm gear; a lock catch assembly on the base body comprises a rack and a positioning strip, the rack is meshed with the worm gear, the rack moves to or away from the positioning strip, and lock catches are arranged at the free end of the rack and the free end of the positioning strip respectively; the base body is provided with a control unit; the control unit comprises a processing module, a USB socket and a motor, the processing module sends a control signal to the motor after receiving an authentication signal output by the USB socket, and the motor is connected with the worm. By means of the structure, the self-locking assembly can achieve self-locking, an operator cannot damage the self-locking assembly after an exhibit is fixed on the lock catch assembly, and the anti-theft effect is achieved; assembling holes in the base body are blocked and cannot be detached, and accordingly the anti-theft force is enhanced.

Description

technical field [0001] The invention relates to the technical field of display appliances, in particular to a worm self-locking card display seat and a control method thereof. Background technique [0002] Electronic exhibits such as mobile phones and tablet computers on the market usually need to be placed on display racks for display so that customers can understand the performance of electronic exhibits. A display rack with anti-theft methods, for example: 1. Set an abnormal alarm function on the display rack of electronic exhibits. When the electronic exhibits on the pallet of the display rack are separated from the pallet, the induction alarm switch will be triggered to make the alarm sound. Alarm sound; 2. Mechanical anti-theft and anti-robbery display stand. [0003] However, although the above two methods can achieve a certain degree of anti-theft, the above two anti-theft methods are also easy to crack, the anti-theft is not thorough enough, and the operation of fi...
