Description

Technical Field

[0001] This utility model relates to the field of display screen technology, specifically to an upper and lower locking structure for an LED display screen module. Background Technology

[0002] LED displays are one of the essential electronic products in modern life. They are used in many situations. Different sizes of displays can be selected according to the needs of different applications. Large screens are often required, and they are made up of multiple LED display modules.

[0003] During splicing, each display module needs to be spliced ​​and locked in all four directions (top, bottom, left, and right). However, in the existing splicing structure, screws are needed to secure each splice, and the screws also need to be unscrewed during disassembly. This hinders the installation of LED display modules and reduces installation efficiency.

[0004] To address this, a locking structure for LED display modules is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide an upper and lower locking structure for LED display modules. By setting up a magnetic base, a connecting base, a positioning rod, and a positioning hole, the magnetic base forms an attractive force on the connecting base. After the positioning rod is placed into the positioning hole, the pre-installation of the two display module bodies can be completed, thereby solving the problem of low splicing installation efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An LED display module upper and lower locking structure includes a display module body, a positioning rod, a magnetic base, and a connecting base. The magnetic base is fixedly installed on the top wall of the display module body, and the connecting base is fixedly installed on the bottom of the display module body. There are two magnetic bases and two connecting bases, which are vertically aligned. A positioning rod is fixedly connected to each connecting base, and a positioning hole is provided on each magnetic base. A locking mechanism for locking the positioning rod is provided on the magnetic base.

[0007] Preferably, the top of the positioning hole is chamfered to form a tapered hole, and the bottom of the positioning rod is also chamfered.

[0008] Preferably, the magnetic base has a cavity inside, a screw is threadedly connected to the magnetic base, a pressure plate is rotatably mounted on one end of the screw, the pressure plate is located in the cavity, and the positioning hole has a notch in the part of the cavity, the notch facing the pressure plate.

[0009] Preferably, the top of the display module body is provided with a positioning groove, and the bottom of the display module body is fixedly installed with a positioning block. The positioning groove and the positioning block are located on the side wall of the display module body.

[0010] Preferably, the top of the positioning groove is chamfered, and the bottom of the positioning block is chamfered.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The system includes a magnetic base and a connecting base, as well as a positioning rod and a positioning hole. When installing the display modules, the positioning rod is placed on the positioning hole. Due to the magnetic attraction between the magnetic base and the connecting base, the connecting base is attracted to the magnetic base when it is above the magnetic base. The positioning rod then enters the positioning hole, allowing the two display modules to be pre-connected. Due to the magnetic attraction and the limiting effect of the positioning rod, the display modules will not fall off after being released by hand. The positioning rod is then locked in place using a locking mechanism, allowing for quick completion of the vertical connection operation between the two display modules. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1 to 4 This utility model provides an upper and lower locking structure for an LED display module, the technical solution of which is as follows: An LED display module upper and lower locking structure includes a display module body 1, a positioning rod 2, a magnetic base 3, and a connecting base 8. The magnetic base 3 is fixedly installed on the top wall of the display module body 1, and the connecting base 8 is fixedly installed on the bottom of the display module body 1. There are two magnetic bases 3 and two connecting bases 8.

[0016] The connecting seat 8 and the magnetic seat 3 are vertically aligned. The magnetic seat 3 is made of a strong magnet, and the connecting seat 8 is made of an iron-containing material.

[0017] Each of the connecting seats 8 is fixedly connected to a positioning rod 2, and each of the magnetic seats 3 is provided with a positioning hole 4. The magnetic seats 3 are provided with a locking mechanism to lock the positioning rod 2.

[0018] When installing the display module body 1, the positioning rod 2 is placed on the positioning hole 4. Since the magnetic seat 3 has a magnetic attraction to the connecting seat 8, when the connecting seat 8 is above the magnetic seat 3, the attraction force will attract the connecting seat 8 to the magnetic seat 3. The positioning rod 2 enters the positioning hole 4, so that the two display module bodies 1 are pre-connected. Due to the magnetic attraction and the limiting effect of the positioning rod 2, the display module will not fall off after being released by hand.

[0019] The top of the positioning hole 4 is chamfered, making the positioning hole 4 a conical hole, and the bottom of the positioning rod 2 is also chamfered.

[0020] With this setup, when placing the display module, simply align the positioning rod 2 above the positioning hole 4. Under the magnetic attraction, the positioning rod 2 moves downward and slides along the chamfer direction to the center of the positioning hole 4. Only rough positioning is required manually, making the docking more convenient and efficient.

[0021] The magnetic base 3 has a cavity 6 inside, and a screw 7 is threadedly connected to the magnetic base 3. A pressure plate 5 is rotatably installed at one end of the screw 7. The pressure plate 5 is located inside the cavity 6. The positioning hole 4 has a notch in the part of the cavity 6, and the notch faces the pressure plate 5.

[0022] After the positioning rod 2 is fully inserted into the positioning hole 4 and completes the coarse positioning, the screw 7 is rotated to move the pressure plate 5 in the cavity 6. One end of the pressure plate 5 applies pressure to the positioning rod 2, so that the positioning rod 2 is fixed and the stability of the installation and docking is improved.

[0023] The top of the display module body 1 is provided with a positioning groove 9, and the bottom of the display module body 1 is fixedly installed with a positioning block 10. The positioning groove 9 and the positioning block 10 are located on the side wall of the display module body 1. The top of the positioning groove 9 is chamfered, and the bottom of the positioning block 10 is chamfered.

[0024] The chamfering allows the top of the positioning groove 9 and the bottom of the positioning block 10 to have an automatic guiding function, so that the positioning block 10 can quickly slide into the positioning groove 9. The positioning groove 9 increases the support area between the two modules, increases the lateral support force, and makes the positioning rod 2 less likely to bend under stress.

[0025] It is worth noting that this solution explains the structure of the upper and lower joints. In actual use, side joints are required. Side joints can be made by riveting, bolting, etc., but these are not the technical points of this application.

[0026] 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.
