Description

Worm self-locking card display base and control method thereof
Technical Field
The invention relates to the technical field of display tools, in particular to a worm self-locking card display seat and a control method thereof.
Background
Electronic exhibits such as cell-phone, panel computer on the market usually need place on the show shelf and be used for the show to be convenient for customers to know the performance of electronic exhibit, because electronic exhibits such as cell-phone, panel computer are expensive, therefore for theftproof, the show shelf of multiple theftproof mode also appears in the market, for example: 1. an abnormal alarm function is arranged on a display rack of the electronic exhibit, and when the electronic exhibit arranged on a supporting plate of the display rack is separated from the supporting plate, an induction alarm switch is triggered to make an alarm send out an alarm sound; 2. a mechanical anti-theft and anti-robbery display base.
However, although the above two anti-theft modes can achieve a certain degree of anti-theft, the above two anti-theft modes are easy to break, the anti-theft is not thorough enough, and the operation of fixing or releasing the exhibit is troublesome.
Disclosure of Invention
The invention mainly aims to provide a worm self-locking card display seat with strong anti-theft strength and easy operation and a control method thereof.
In order to achieve the above-mentioned main object, the present invention provides a display seat of worm self-locking card, comprising:
a base including a bottom plate;
the self-locking assembly is arranged in the base and comprises a worm and a worm wheel meshed with the worm, and the lead angle of the worm is smaller than the equivalent friction angle between teeth of the worm wheel;
the lock catch component is arranged on the base and comprises a rack, the rack is meshed with the worm wheel, and a first lock catch is arranged at the free end of the rack.
Therefore, the lead angle of the worm is smaller than the equivalent friction angle between the saw teeth of the worm wheel, the self-locking assembly has self-locking performance, namely the worm wheel can only be driven by the worm, but not be driven to the worm by the worm wheel, an operator cannot drive the worm wheel to rotate by pulling the rack, and therefore the locking assembly cannot move, and the anti-theft function is achieved. When locking, can set up another hasp on the desktop of placing the showpiece, set up the showpiece between two hasps, manual twisting changes the worm, and the worm is rotatory to be driven the worm wheel and is rotated, and the worm wheel drives the rack motion with worm wheel meshing during rotation, thereby the fixed showpiece of distance between first hasp on the free end of rack and another hasp subtracts the weak point, and it is convenient fast to operate, and the direction of rotation of worm is opposite when launching the showpiece the direction of rotation of worm and when fixing the showpiece.
The further scheme is that the locking assembly comprises a positioning strip, the positioning strip is fixed on the base, a second locking buckle is arranged at the free end of the positioning strip, and the rack moves towards or away from the positioning strip.
It is thus clear that worm wheel rotates the removal that drives the removal rack, and the location strip is fixed on the base, and the location strip does not take place to remove, along with the removal of rack, shortens or increases the distance of the first hasp on the rack and the second hasp on the location strip to the realization is fixed or is released the showpiece.
The other scheme is that sawteeth are arranged on the positioning strip, the positioning strip is meshed with the worm wheel, the rack moves towards or away from the positioning strip, and the positioning strip moves towards or away from the rack.
Therefore, the rack and the positioning strip are meshed with the worm wheel, namely, the worm wheel drives the rack and the positioning strip to move simultaneously when rotating.
The base further comprises a side plate, the side plate is provided with a first opening, the axis direction of the worm is communicated with the first opening, the worm comprises an operation portion, the bottom plate is provided with a second opening, an isolation block is arranged between the first opening and the operation portion, and the isolation block penetrates through the second opening.
After the exhibit is fixed, the isolation block is arranged between the first opening and the worm to isolate the first opening and the worm, so that the worm cannot be manually screwed through the first opening, and further the anti-theft effect is realized; because the lock catch component is arranged above the base, the exhibit completely covers the base, and the first opening on the side plate is separated by the separation block, so that the visible assembly hole on the base is blocked and cannot be detached, and the anti-theft strength is enhanced; the bottom plate contacts with the desktop of the display base, the second opening is hidden after the display base is installed, the isolation block penetrates through the second opening in the bottom plate to separate the first opening from the worm, visible installation positions are reduced, and further burglary prevention is achieved.
The other scheme is that a gear is coaxially arranged on the worm wheel, the rack is meshed with the gear, a sliding groove is formed in the rack, and the gear penetrates through the sliding groove of the rack.
Therefore, the rack in the lock catch assembly can be directly meshed with the gear coaxially arranged with the worm wheel, and the gear drives the rack to move.
The invention provides a worm self-locking card display seat which comprises a base, wherein the base comprises a bottom plate;
the self-locking assembly is arranged in the base and comprises a worm and a worm wheel meshed with the worm, and the lead angle of the worm is smaller than the equivalent friction angle between teeth of the worm wheel;

the control method of the worm self-locking card display seat comprises the following steps:
s1, after the processing module 40 receives the unlocking signal through the USB socket 41, the processing module 40 outputs a control signal to the motor 44;
s2, the motor 44 drives the worm 21 to rotate according to the control signal;
s3, the worm 21 rotates to drive the worm wheel 22 to rotate;
s4, the rotation of the worm wheel 21 drives the rack 31 to move.
By utilizing the control method, the driving worm 21 can be controlled, so that the rotation of the worm 21 is realized under the driving of the motor 44, the worm 21 rotates to drive the worm wheel 22 to rotate, the rack 31 is driven to move, the distance between the first lock catch 34 and the other lock catch on the rack 31 is shortened or increased, the locking/unlocking of the exhibit is realized, wherein the moving direction of the rack 31 in the locking process is opposite to the moving direction of the rack 31 in the unlocking process, the fixation and the release of the exhibit can be automatically carried out as long as a USB key is inserted, and the operation is convenient and fast.
Finally, it should be emphasized that the present invention is not limited to the above-mentioned embodiments, and variations such as the partition manner of the isolation block, the shapes of the first locking device and the second locking device, the number of the racks, etc. should also be included in the protection scope of the claims of the present invention.
