Description

Technical Field

[0001] This utility model belongs to the field of display screen technology, and in particular relates to a magnetic liquid crystal display screen. Background Technology

[0002] In the field of LCD screen installation, traditional fixing methods mostly rely on bolt connections. When using bolt connections, multiple tightening operations are required with the help of tools. Not only is the installation and disassembly process cumbersome and inefficient, but repeated disassembly and assembly can also lead to thread wear, affecting the stability of the connection.

[0003] In the existing technology, some displays attempt to use magnetic attraction to assist in installation in order to simplify the disassembly and assembly process. However, there is often a problem of insufficient positioning accuracy. The magnetic attraction structure is prone to displacement during the adsorption process, which causes a deviation in the relative position between the display and the mounting bracket, affecting the overall assembly accuracy and the use effect.

[0004] In addition, most display screen mounting structures do not provide sufficient protection for the display screen. During installation, the hard contact between the display screen and the mounting bracket can easily cause wear and tear on the edges and corners. During use, external collisions and pressure may also damage the display screen body, affecting its service life and display performance. Utility Model Content

[0005] The technical problem this invention aims to solve is that the adsorption process is prone to displacement, which leads to a deviation in the relative position between the display screen and the mounting bracket, and external collisions and compression can damage the display screen body.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a magnetically attached liquid crystal display screen, comprising an X-shaped mounting bracket, wherein the display screen body is detachably attached to one side of the mounting bracket, and further comprising...

[0007] A connecting assembly, mounted on a mounting frame, includes a cylinder fixedly connected to the center of the outer wall of the mounting frame, an electromagnet fixedly connected to the inner wall of the cylinder, a post fixedly connected to the center of the outer wall of the display screen body, a horizontal sliding post sliding at one end of the post, a spring fixedly connected between the sliding post and the inner wall of the post, and the sliding post being made of metal.

[0008] Furthermore, the outer wall of the mounting bracket is fixedly connected with centrally symmetrically distributed fixing cylinders, and the outer wall of the display screen body is fixedly connected with two symmetrically distributed positioning columns, which are inserted into the inside of the fixing cylinders.

[0009] Furthermore, the positioning column is hollow inside, and a stroke hole is opened at its end. A rubber block is fixedly connected to the bottom of the fixed cylinder, and a positioning block is fixedly connected to the top of the rubber block. The positioning block has symmetrically distributed slots on its inner wall.

[0010] An inner block is fixedly connected between the inner walls of the positioning column. A vertical rod slides on the inner block. A sliding block is fixedly connected to the end of the vertical rod, and both ends of the vertical rod move through the stroke hole. A round block is fixedly connected to the vertical rod. A spring is sleeved on the vertical rod, and its two ends are fixedly connected to the inner block and the round block. A symmetrically distributed positioning rod slides on the side wall of the positioning column. The positioning rod is adapted to the slot. A spring is fixedly connected between the opposite side walls of the positioning rod. A connecting rod is hinged between the lower end of the vertical rod and the positioning rod.

[0011] Furthermore, the outer wall of the display screen body is fixedly connected with centrally symmetrically distributed inserts, and the outer wall of the mounting bracket is fixedly connected with centrally symmetrically distributed inserts. The inserts are arranged in a cross shape and are inserted into the interior of the inserts.

[0012] Furthermore, the mounting frame is fixedly connected with connecting frames that are symmetrically distributed vertically, and the ends of the connecting frames are fixedly connected with L-shaped protective plates. Side frames are fixedly connected to both sides of the mounting frame, and the ends of the side frames are fixedly connected with L-shaped side plates.

[0013] Furthermore, the outer wall of the protective plate and the outer wall of the side plate are both provided with rubber pads.

[0014] The beneficial effects of this utility model after adopting the above structure are as follows:

[0015] (1) By engaging the positioning rod with the slot and magnetically fixing the electromagnet with the sliding column, a dual installation structure is formed, which greatly improves the stability and firmness of the connection between the display screen body and the mounting bracket, and effectively avoids loosening after installation.

[0016] (2) When the display screen is subjected to external impact or pressure, the spring and rubber block can buffer the impact force through deformation, and the protective plate, side plate and rubber pads on them can further absorb the external force. The multiple protective structures significantly reduce the risk of damage to the display screen body by external force and extend its service life.

[0017] (3) When disassembling, simply turn off the electromagnet and move the sliding block to release the positioning and magnetic fixation. No complicated tools or cumbersome operations are required, which greatly simplifies the disassembly process of the display screen body, facilitates quick maintenance or replacement, and improves operating efficiency.

[0025] like Figure 1-2 As shown, a magnetic liquid crystal display screen includes an X-shaped mounting bracket 1, a display screen body 2 detachably attached to one side of the mounting bracket 1, and a connecting component disposed on the mounting bracket 1.

[0026] like Figure 1-4 As shown, in order to facilitate the splicing and installation of the display screen body 2, the outer wall of the display screen body is fixedly connected with centrally symmetrically distributed insert blocks 21, and the outer wall of the mounting frame 1 is fixedly connected with centrally symmetrically distributed insert cylinders 22. The insert blocks 21 are arranged in a cross shape and are inserted into the inside of the insert cylinders 22. The connecting components include a cylinder 3 fixedly connected to the center of the outer wall of the mounting frame 1, an electromagnet 4 fixedly connected to the inner wall of the cylinder 3, an insert post 5 fixedly connected to the center of the outer wall of the display screen body 2, a horizontal sliding post 6 sliding at one end of the insert post 5, a spring 7 fixedly connected between the sliding post 6 and the inner wall of the insert post 5, the sliding post 6 being made of metal, a centrally symmetrically distributed fixing cylinder 8 fixedly connected to the outer wall of the mounting frame 1, and two symmetrically distributed positioning posts 9 fixedly connected to the outer wall of the display screen body 2, the positioning posts 9 being inserted into the inside of the fixing cylinder 8.

[0027] like Figure 1-5As shown, to increase the stability of the splicing, the positioning post 9 is hollow inside, with a stroke hole 10 at its end. A rubber block 11 is fixedly connected to the bottom of the fixing cylinder 8, and a positioning block 12 is fixedly connected to the top of the rubber block 11. The inner wall of the positioning block 12 has symmetrically distributed slots 13. An inner block 14 is fixedly connected between the inner walls of the positioning post 9. A vertical rod 15 slides on the inner block 14. A sliding block 16 is fixedly connected to the end of the vertical rod 15, and both ends of the sliding block 16 move through the stroke hole 10. A round block 17 is fixedly connected to the vertical rod 15, and a spring 1 is sleeved on the vertical rod 15. 8. The inner block 14 and the round block 17 are fixedly connected at both ends. The positioning post 9 has symmetrically distributed positioning rods 19 sliding on its side wall. The positioning rods 19 and the slot 13 are compatible. The positioning rods 19 are fixedly connected to the opposite side wall of the side wall. The lower end of the vertical rod 15 is hinged to the positioning rod 19 with a connecting rod 28. Through the snap-fit ​​cooperation between the positioning rod 19 and the slot 13 and the magnetic attraction fixation between the electromagnet 4 and the sliding post 6, a double installation structure is formed, which greatly improves the stability and firmness of the connection between the display body 2 and the mounting bracket 1, and effectively avoids loosening after installation.

[0028] To protect the sides of the display screen body 2, the mounting bracket 1 is fixedly connected with symmetrically distributed connecting brackets 23. The ends of the connecting brackets 23 are fixedly connected with L-shaped protective plates 24. Side brackets 25 are fixedly connected to both sides of the mounting bracket 1. The ends of the side brackets 25 are fixedly connected with L-shaped side plates 26. Rubber pads 27 are provided on the outer walls of the protective plates 24 and the side plates 26. When the display screen is subjected to external impact or pressure, the spring 7 and the rubber block 11 can buffer the impact force through deformation. The protective plates 24, the side plates 26 and the rubber pads 27 on them can further absorb the external force. The multiple protective structures significantly reduce the risk of damage to the display screen body 2 from external forces and extend its service life.

[0029] In practical use, when installing the display screen body 2, pull the sliding block 16 to make the vertical rod 15 slide on the inner block 14. The second spring 18 deforms, and the two sets of positioning rods 19 slide relative to each other under the action of the connecting rod 28, compressing the third spring 20. Then, align the insert block 21 with the insert cylinder 22 and insert it. At this time, the positioning pin 9 is also inserted into the fixed cylinder 8 and the sliding pin 6 is inserted into the cylinder 3. After the positioning pin 9 is inserted into the positioning block 12, release the sliding block 16 so that the positioning rod 19 can be inserted into the slot 13 under the action of the second spring 18 and the third spring 20. When the electromagnet 4 is turned on, it will attract the sliding post 6. The two installation methods ensure the stability of the installation. When the display screen is subjected to external impact or pressure, the spring 7 deforms and the insertion post 5 slides in the cylinder 3. The positioning post 9 presses the positioning block 12 and deforms the rubber block 11. In addition, the rubber pads 27 on the protective plate 24 and the side plate 26 can increase the protection effect of the display screen body 2. When disassembling and maintaining the display screen body 2, it is only necessary to turn off the electromagnet 4 and move the sliding block 16 at the same time to remove the display screen body 2 from the mounting bracket 1.
