Description

Technical Field

[0001] This utility model relates to the field of electronic price tag technology, specifically an anti-theft electronic price tag. Background Technology

[0002] Electronic shelf labels are intelligent display devices primarily used in retail settings to replace traditional paper labels. They integrate an electronic display screen, memory, and microprocessor, and connect to a back-end system via a wireless network to enable real-time updates and unified management of data such as product prices and promotional information. They offer advantages such as high efficiency, environmental friendliness, and flexible display capabilities.

[0003] Chinese patent CN218005262U discloses an electronic shelf label, comprising: adding a passive NFC antenna, which is electrically disconnected from the existing NFC antenna, outside the PCB of the electronic shelf label; this passive NFC antenna is coupled to the existing NFC antenna. This invention can improve the NFC signal strength and field strength distribution near the screen of the electronic shelf label, and enhance the NFC communication distance, effective sensing area, and trigger response speed, especially when the size of the electronic shelf label is limited and the NFC antenna is obstructed by the screen, battery, structural components, etc.

[0004] The above-mentioned solutions and existing technologies for fixing electronic shelf labels typically involve placing them directly on the shelf slide, sticking them to the shelf with adhesive backing, or fixing them to the shelf using clips. These fixing methods are usually not secure enough and do not have anti-theft effects, making it easy for electronic shelf labels to be stolen. This results in direct economic losses and indirectly affects subsequent consumers' ability to view prices and make purchases. Therefore, there is a lack of electronic shelf labels with corresponding anti-theft structures, which need to be improved and optimized. Utility Model Content

Detailed Implementation

[0022] The technical solutions in the embodiments of this utility model will be clearly and completely described below. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1 to 6 This utility model provides the following two technical solutions:

[0024] Example 1: An anti-theft electronic price tag includes an electronic price tag body 1. One end of the electronic price tag body 1 is fixedly connected to a plug plate 2. The plug plate 2 is plugged into a mounting plate 3. The mounting plate 3 has symmetrical fixing holes 301 at both ends. The mounting plate 3 has a square slot 302 in the middle. The mounting plate 3 has an anti-theft locking component in the middle. One end of the anti-theft locking component is plugged into a key component.

[0025] In use, the mounting plate 3 is fixedly installed on the shelf using screws through the fixing holes 301, and then the insert plate 2 on the back of the electronic price tag body 1 is inserted into the square slot 302. The insert plate 2 and the electronic price tag body 1 are locked by the anti-theft locking component.

[0026] Example 2: Based on Example 1, the insert plate 2 has three sets of locking grooves 201 arranged diagonally from top to bottom on one end. Below the uppermost set of locking grooves 201 on the insert plate 2 is an anti-theft lock groove 202. The anti-theft locking assembly includes a pin groove 401, an anti-theft pin groove 402, a square lock hole 403, a triangular lock hole 404, and a cylindrical lock hole 405. The pin groove 401 is located in the middle of the mounting plate 3, the anti-theft pin groove 402 is located in the middle of the mounting plate 3, the square lock hole 403 is located at one end of the mounting plate 3, the triangular lock hole 404 is located at one end of the mounting plate 3, and the cylindrical lock hole 405 is located at one end of the mounting plate 3. One end of the square lock hole 403 is connected to a set of pin grooves 401 and the anti-theft pin groove 402, one end of the triangular lock hole 404 is connected to another set of pin grooves 401, and one end of the cylindrical lock hole 405 is connected to a third set of pin grooves 401. The pin groove 401 corresponds to three sets of locking grooves 201 in sequence, and the anti-theft pin groove 402 corresponds to the anti-theft lock groove 202. A pin 406 is inserted into the pin groove 401, and a first spring 407 is fixedly connected to one end of the pin 406. One end of the first spring 407 is fixedly connected to the inner wall of the pin groove 401. An anti-theft pin 408 is inserted into the anti-theft pin groove 402, and a second spring 409 is fixedly connected to one end of the anti-theft pin 408. One end of the second spring 409 is fixedly connected to the inner wall of the anti-theft pin groove 402. The key assembly includes a handle 501, and a square pin 502, a triangular pin 503, and a cylindrical pin 504 are fixedly connected to one end of the handle 501 in sequence. The square pin 502 corresponds to the square lock hole 403, the triangular pin 503 corresponds to the triangular lock hole 404, and the cylindrical pin 504 corresponds to the cylindrical lock hole 405.

[0027] In use, the three sets of pins 406 on the anti-theft locking assembly extend out of the pin slots 401 under the compression of the first spring 407. When the insert plate 2 is inserted into the square slot 302, the pins 406 are sequentially inserted into the locking slots 201 on the insert plate 2 for fixing. When it is necessary to release the fixing, take out the special key assembly, hold the handle 501 and align the square pin 502, triangular pin 503 and cylindrical pin 504 sequentially with the square lock hole 403, triangular lock hole 404 and cylindrical lock hole 405. When inserting, the three sets of pins 406 are pressed against the arc-shaped surface on one side, causing them to move backward and disengage from the locking groove 201, thus unlocking the electronic price tag body 1. If a thief uses three substitute pins of different lengths to insert into the lock hole, when the shorter square pin 502 is inserted into the square lock hole 403, the longer substitute pin will press against the arc-shaped surface on one side of the anti-theft pin 408, causing it to insert into the anti-theft pin groove 402 for locking. Even if the three sets of pins 406 are unlocked, the electronic price tag body 1 still cannot be removed.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
