[0002] An LED display screen refers to a new imaging electronic device made by arranging light-emitting diodes in sequence. In large-scale activities, large-sized LED display screens are commonly used to convey relevant information of the activities to people, and large-sized LED display screens need to be assembled by multiple LED display screen unit boards.

[0003] Currently, when assembling LED display screen unit boards into a large-sized LED display screen, installers need to manually assemble the LED display screen unit boards together, and also need to additionally use fixing tools such as screwdrivers and screws. Not only do they need to carry the fixing tools additionally, but the installation is also rather cumbersome. Therefore, an LED display screen unit board which is convenient for installation is now developed. Content of the Utility Model

[0004] In order to overcome the disadvantage that the current LED display screen unit board is not convenient for installation and combination, the utility model provides an LED display screen unit board which is convenient for installation.

[0005] The technical implementation scheme of the utility model is as follows: An LED display screen unit board which is convenient for installation includes a first fixing rod. The number of the first fixing rods is three, and the three first fixing rods are distributed at equal intervals. The unit board modules are divided into two rows which are distributed up and down. One side of the unit board module close to the adjacent first fixing rod is slidably connected with a first limiting frame, and the first limiting frame is clamped with the adjacent first fixing rod. The unit board module is fixedly connected with symmetrically distributed fixing frames. It also includes a first fixing plate. The number of the first fixing plates is twice the number of the first fixing rods. The first fixing plates are symmetrically fixedly connected to the first fixing rods. One side of the first fixing plate close to the adjacent unit board module is fixedly connected with a connecting frame. The connecting frame is slidably matched with the two adjacent fixing frames.

A clamping frame is slidably connected to the limiting sleeve. The clamping frame is inserted and matched with the adjacent fixing frame, the clamping frame is inserted and matched with the adjacent first limiting frame, and the clamping frame is inserted and matched with the adjacent first fixing rod.

[0006] As a further preferred scheme, it also includes a stabilizing mechanism. The stabilizing mechanism includes a second fixing plate. The number of the second fixing plates is equal to the number of the unit board modules. The second fixing plates are respectively fixedly connected to the unit board modules. A pushing frame is slidably connected to the second fixing plate. A magnetic strip is fixedly connected to the pushing frame. The magnetic strips attract each other. Trigger components are arranged on the pushing frames.

[0007] As a further preferred solution, it further includes an elastic member, and the elastic member is symmetrically fixedly connected between the pushing frame and the adjacent second fixing plate.

[0008] As a further preferred solution, the triggering assembly includes a pressing frame, the number of pressing frames is equal to the number of pushing frames, the pressing frames are respectively fixedly connected to the pushing frames, a second fixing rod is fixedly connected to one side of the connecting frame close to the adjacent pressing frame, and the second fixing rod and the adjacent pressing frame are in pressing cooperation.

[0010] As a further preferred solution, a plurality of holes are formed in the lower part of the second limiting frame, and the caliber of the holes in the second limiting frame is small at the top and large at the bottom, and the inner wall of the holes is smooth.

[0011] The beneficial effects of the present utility model are as follows:

[0012] The present utility model can complete the installation by simply moving the unit board module and the pushing and clamping frame, without the need to take additional installation tools, thus making the installation more convenient.

[0013] The present utility model uses the second fixing rod to push the pressing frame, so that the pressing frame drives the pushing strip and the magnetic strip to move, thereby further fixing the adjacent unit board modules on the left and right sides by the attraction of the two magnetic strips.

[0014] The present utility model can further strengthen the connection between the unit board modules on the upper and lower sides by the clamping and attraction of the first friction ring and the second friction ring. Description of the Drawings

Detailed implementation manners

[0021] The present utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but it is not limited to the present utility model.

[0022] Embodiment 1: An LED display unit board that is easy to install, as Figure 1 and Figure 2 shown, includes three first fixing rods 1. The three first fixing rods 1 are equally spaced from left to right. There are eight unit board modules 2, which are divided into two rows, upper and lower. Each row has four unit board modules 2 from left to right. The unit board modules 2 can be snap-fitted together vertically. The unit board modules 2 are all located at the rear side of the first fixing rods 1. One side of each unit board module 2 close to the adjacent first fixing rod 1 is slidably connected with a first limiting frame 3, and the first limiting frames 3 are all snap-fitted with the adjacent first fixing rods 1. By snap-fitting the first limiting frames 3 with the adjacent first fixing rods 1, the limitation of each unit board module 2 can be realized. Fixing frames 4 are fixedly connected to the left and right sides of the front part of the unit board module 2. It also includes a first fixing plate 5. The number of the first fixing plates 5 is twice the number of the first fixing rods 1. The first fixing plates 5 are respectively fixedly connected to the upper and lower sides of the front part of the first fixing rods 1. One side of each first fixing plate 5 close to the adjacent unit board module 2 is fixedly connected with a connecting frame 6. The connecting frames 6 are all slidably matched with the adjacent two fixing frames 4. Two limiting sleeves 7 are fixedly connected to one side of the front part of each connecting frame 6 close to the adjacent unit board module 2. Clamping frames 8 are slidably connected to the limiting sleeves 7. The clamping frames 8 are all inserted and matched with the adjacent two fixing frames 4, the clamping frames 8 are all inserted and matched with the adjacent first limiting frames 3, and the clamping frames 8 are all inserted and matched with the adjacent first fixing rods 1. By guiding the adjacent first limiting frames 3 with the clamping frames 8, the first limiting frames 3 can be accurately snapped onto the adjacent first fixing rods 1.

[0023] When installing this LED display unit board, first, the first fixing rod 1 needs to be fixed on the ground. When fixing the first fixing rod 1, the first fixing plate 5 will be fixed accordingly. Then, move the first limiting frame 3 so that the first limiting frame 3 moves towards the side close to the adjacent fixing frame 4. Next, move the unit board module 2 from back to front close to the connecting frame 6 so that the fixing frame 4 can be stuck on the connecting frame 6. Then, move the unit board module 2 downward so that the fixing frame 4 moves downward until it is directly opposite to the clamping frame 8. Then, push the clamping frame 8 towards the side close to the adjacent first fixing rod 1 so that the clamping frame 8 is inserted into the fixing frame 4. When the clamping frame 8 moves, the clamping frame 8 will also push the first limiting frame 3 to move synchronously. Finally, the clamping frame 8 will be inserted into the adjacent first fixing rod 1, and at the same time, the limiting frame will also be clamped on the adjacent first fixing rod 1. In this way, one unit board module 2 can be fixed on the first fixing rod 1. Then, use the same method to fix all the unit board modules 2 on the first fixing rod 1. When installing, it should be noted that the unit board modules 2 on the lower side should be installed first, and then the unit board modules 2 on the upper side. The unit board modules 2 can be fixed together by means of upper and lower clamping. In this way, the unit board modules 2 can be assembled into a large-sized LED screen, so that there is no need to take additional installation tools, and the installation can be completed only by simply moving the unit board module 2 and pushing the clamping frame 8. When disassembling, the clamping frame 8 needs to be pushed in the reverse direction so that the clamping frame 8 releases the fixing frame 4, and at the same time, the clamping frame 8 guides the first limiting frame 3 to release the first fixing rod 1. Then, move the unit board module 2 on the lower side downward so that the unit board modules 2 on the upper and lower sides are separated. Then, move the unit board module 2 backward so that the unit board module 2 is far away from the first fixing rod 1 and the first fixing plate 5, thus facilitating the storage of the unit board module 2.

[0024] Embodiment 2: On the basis of Embodiment 1, as Figure 1 and Figure 4 shown, it further includes a stabilizing mechanism. The stabilizing mechanism includes a second fixing plate 9. The number of the second fixing plates 9 is equal to the number of the unit board modules 2. The second fixing plates 9 are respectively fixedly connected to the unit board modules 2. A pushing frame 10 is slidably connected to each of the second fixing plates 9. A magnetic strip 11 is fixedly connected to each of the pushing frames 10. The magnetic strips 11 attract each other. A triggering component is arranged on each of the pushing frames 10.

[0025] As Figure 4 shown, it further includes an elastic member 12. The elastic member 12 is symmetrically fixedly connected between the pushing frame 10 and the adjacent second fixing plate 9.

[0026] As Figure 1 and Figure 4As shown, the triggering component includes a pressing frame 14. The number of pressing frames 14 is equal to the number of pushing frames 10. The pressing frames 14 are respectively fixedly connected to the pushing frames 10. Second fixing rods 13 are fixedly connected to one side of the connecting frame 6 close to the adjacent pressing frames 14, and the second fixing rods 13 are in pressing cooperation with the adjacent pressing frames 14.

[0027] In order to make the connection between the adjacent unit board modules 2 on the left and right closer, they can be attracted to each other by the magnetic strips 11, so as to adsorb the adjacent unit board modules 2 on the left and right together. When the unit board modules 2 on the left and right sides have not approached yet, the elastic members 12 are in a state of neither stretching nor compressing. As the unit board modules 2 move forward, the pushing frames 10, the elastic members 12, the magnetic strips 11, and the pressing frames 14 all move forward. When the pressing frame 14 contacts the second fixing rod 13, under the extrusion of the second fixing rod 13, the pressing frame 14 will drive the pushing frame 10 to move, so that the pushing frame 10 moves toward the side away from the adjacent connecting frame 6, and the elastic member 12 stretches, so that the magnetic strips 11 on the two different unit board modules 2 on the left and right can be adsorbed together, further fixing the unit board modules 2 on the left and right sides. When the unit board modules 2 move backward, the second fixing rod 13 releases the pressing frame 14, and under the action of the elastic member 12, the pushing frame 10 drives the magnetic strip 11 to move in the reverse direction, so that the two magnetic strips 11 can be separated.

[0028] As Figure 1 and Figure 5 shown, it further includes a limiting mechanism. The limiting mechanism includes a second limiting frame 15. The number of second limiting frames 15 is equal to the number of unit board modules 2. The second limiting frames 15 are respectively fixedly connected to the unit board modules 2. Four openings are formed in the lower part of the second limiting frame 15, and the caliber of the openings in the lower part of the second limiting frame 15 is small at the top and large at the bottom, and the inner wall of the opening is smooth. First friction rings 16 are fixedly connected to the left and right sides of the upper part of the second limiting frame 15, and second friction rings 17 are fixedly connected to the left and right sides of the lower part of the second limiting frame 15. The first friction rings 16 and the second friction rings 17 are magnetically attracted to each other.

[0029] In order to further strengthen the connection between the unit board modules 2 on the upper and lower sides, when the unit board modules 2 on the upper and lower sides are clamped together, the first friction ring 16 will also be sleeved with the adjacent second friction ring 17. Also, because the first friction ring 16 and the second friction ring 17 can be magnetically attracted to each other, the connection between the unit board modules 2 on the upper and lower sides can be further strengthened. Since four openings are formed in the lower part of the second limiting frame 15, and the caliber of the openings in the lower part of the second limiting frame 15 is small at the top and large at the bottom, and the inner wall of the opening is smooth, the openings can play a guiding role for the first friction ring 16 and the unit board module 2, and the operator does not need to accurately align with the openings when installing to clamp the unit board modules 2 on the upper and lower sides together.

[0030] The above embodiments are only preferred embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model. Therefore, all equivalent changes made based on the content described in the claims of the present utility model shall be included within the scope of the claims of the present utility model.
