Description

Technical Field

[0001] This utility model relates to the technical field of electronic price tags, and in particular to an electronic price tag communication controller. Background Technology

[0002] An electronic shelf label communication controller is a device that can identify electronic shelf labels. It consists of a host and a scanner. Although existing scanners can identify electronic shelf labels in conjunction with the host, when using a data cable to connect the scanner to the host, if the data cable is too long, it is easy for it to get tangled due to factors such as normal use. Especially in situations with frequent use or a cluttered working environment, organizing and storing the data cable will consume extra time and effort, which will affect the efficiency of updating, managing and controlling electronic shelf label information. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an electronic price tag communication controller.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An electronic price tag communication controller includes a housing, a data cable placed inside the housing, one end of the data cable being installed through the housing, an opening in the housing, the other end of the data cable being movably inserted through the opening, a scanner mounted on the data cable, multiple sets of rubber grooved wheels connected to the housing, the multiple sets of rubber grooved wheels contacting the data cable, a spring-loaded spring being installed between the multiple sets of rubber grooved wheels and the housing, and a platform connected to the housing.

[0006] Preferably, a baffle is rotatably connected to the box body, and magnets are installed at corresponding positions on the baffle and the box body.

[0007] Preferably, the scanner has grooves at one end and the other end, and multiple sets of grooves are slidably connected to the frame, which is connected to the platform.

[0008] Preferably, multiple sets of rollers are rotatably connected at the port, and the data cable is placed between the multiple sets of rollers.

[0009] Preferably, the platform body has multiple sets of mounting holes.

[0010] Preferably, one end of the box body is machined with an opening.

[0011] Preferably, a lever is connected to the baffle.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. Through the coordinated design of the data cable, housing, port, scanner, rubber roller, and spring, the system utilizes the contact between the rubber roller and the data cable, along with the spring's elasticity, to allow the data cable to be pulled out of the housing. This rotation of the rubber roller, in turn, gradually tightens the spring, enabling controlled cable retraction and eliminating the hassle of tangled cables. When the scanner is needed, simply pull the data cable to the desired length for immediate use; after use, the spring's return force smoothly retracts the cable. The entire process is smooth and efficient, significantly reducing time spent tidying up the cable before and after each use, making the work more efficient and organized. This is particularly suitable for busy scenarios such as supermarket checkouts and logistics warehouses where frequent scanner use is required, ensuring efficient updating, management, and control of electronic price tag information.

[0014] 2. By using the combination of the baffle, the box, and the magnet, the baffle rotates at the box. When the magnet at the baffle comes into contact with the magnet at the box, the position of the baffle is fixed by magnetic force. The baffle can then block the opening of the box, making it relatively convenient and time-saving to inspect the inside of the box. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figures 1 to 5 An electronic price tag communication controller includes a housing 1 made of sturdy and lightweight engineering plastic, possessing good insulation properties and a certain impact resistance to protect internal components from external physical damage. Its internal space is carefully designed to accommodate a data cable 2 of a certain length. The data cable 2 is placed inside the housing 1, with one end of the data cable 2 passing through and mounted on the housing 1. An opening 3 is provided in the housing 1, through which the other end of the data cable 2 movably passes. A scanner 4 is mounted on the data cable 2. Multiple sets of rubber grooved wheels 5 are connected to the housing 1. The groove depth and width of the rubber grooved wheels 5 are precisely designed according to the diameter of the data cable 2 to ensure that the data cable 2 can be stably embedded in the groove without excessive compression. The multiple sets of rubber grooved wheels 5 are in contact with the data cable 2. A spring-loaded spring 6 is installed between the multiple sets of rubber grooved wheels 5 and the housing 1. The spring-loaded spring 6 is made of high-strength alloy steel and undergoes a special heat treatment process to give it good elasticity and fatigue life. One end of the spring 6 is fixed to the axis of the rubber grooved wheel 5, and the other end is connected to a fixed point inside the housing 1. When the scanner 4 pulls the data cable 2, the data cable 2 drives the rubber grooved wheel 5 to rotate, and the spring 6 tightens to store elastic potential energy. When the scanner 4 releases the data cable 2, the spring 6 releases the elastic potential energy, driving the rubber grooved wheel 5 to rotate in the opposite direction, smoothly retracting the data cable 2 into the housing 1. The housing 1 is connected to a platform 12. By utilizing the cooperation of the spring 6 and the rubber grooved wheel 5, the data cable 2 can be easily wound up. In this way, the data cable 2 can be controlled to be wound up and unwound, and the operator no longer needs to worry about the messy and tangled data cable 2.

[0023] In this embodiment, a baffle 9 is rotatably connected to the housing 1. Magnets 10 are installed at corresponding locations on both the baffle 9 and the housing 1. The mutual magnetic attraction between the two sets of magnets 10 fixes the baffle 9 to the housing 1, thereby blocking the opening of the housing 1. Grooves 8 are provided at one and the other ends of the scanning gun 4. Multiple sets of grooves 8 are slidably connected to the frame 7. The shape of the grooves 8 matches the slide rail of the frame 7, achieving a slidable connection between the scanning gun 4 and the frame 7. The frame 7 is fixed on the platform 12, providing stable support for the scanning gun 4. When the scanner 4 is not in use, it can be placed on the frame 7 to avoid damage or loss due to random placement. The frame 7 is connected to the platform 12. Multiple sets of rollers 11 are rotatably connected at the through port 3. The data cable 2 is placed between the multiple sets of rollers 11. The rollers 11 are used to prevent the data cable 2 from contacting the through port 3 and to prevent wear on the data cable 2. Multiple sets of mounting holes 13 are opened at the platform 12. An opening is machined at one end of the housing 1 to facilitate the initial installation and daily maintenance of the data cable 2. A lever 14 is connected to the baffle 9.

[0024] The working principle of this embodiment is as follows: When using the handheld scanner 4, the scanner 4 can pull the data cable 2 out of the housing 1. When the data cable 2 is pulled out, it will drive the rubber groove wheel 5 to rotate and gradually tighten the spring 6. When the scanner 4 is reset, the spring 6 can drive the rubber groove wheel 5 to rotate, thereby moving the data cable 2 back into the housing 1 for storage. This can prevent the data cable 2 from being exposed and affecting the work. When it is necessary to inspect the inside of the housing 1, the lever 14 drives the baffle 9 to rotate. The magnet 10 of the baffle 9 can be separated from the magnet 10 of the housing 1. The baffle 9 loses its fixation and exposes the opening of the housing 1, so that the inside of the housing 1 can be inspected.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
