Description

Technical Field

[0001] The utility model relates to the technical field of LED display screens, in particular to a fast-connected LED display screen. Background Art

[0002] LED display is a display device based on LED technology. LED display displays images and video content by controlling pixels composed of thousands of LEDs. It has the characteristics of high brightness, high contrast, wide viewing angle and bright colors. It is suitable for various indoor and outdoor occasions and requires a fast-connected LED display.

[0003] In the prior art, LED display screens generally need to be fixed by a mounting frame, and most LED display screens are fixed to the mounting frame using a plurality of fixing bolts.

[0004] However, when the above device is in use, the staff is required to frequently install the fixing bolts for multiple times, which increases the labor intensity of the staff, reduces the installation efficiency of the LED display screen, and cannot meet the use needs of the staff. A quick-connect LED display screen is needed. Utility Model Content

[0005] The purpose of the utility model is to provide a quick-connect LED display screen to solve the problem proposed in the above background technology that workers are required to frequently install fixing bolts for multiple times, which increases the labor intensity of the workers, reduces the installation efficiency of the LED display screen, and cannot meet the use needs of the workers.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a quick-connect LED display screen, comprising a mounting frame and a display screen body, the bottom inner wall of the mounting frame is provided with an adjustment groove, and adjustment blocks are slidably connected to both sides of the inner wall of the adjustment groove, and a double-headed threaded rod is rotatably connected to the inner wall of one side of the adjustment groove through a bearing, the double-headed threaded rod and the adjustment block are threadedly connected, and a rotating block is fixedly connected to one side of the double-headed threaded rod, a placement groove is provided on the outer wall of one side of the mounting frame, the rotating block is located in the placement groove, a limiting mechanism is provided in the placement groove, a placement plate is provided on the top of the adjustment block, and the display screen body is placed on the placement plate.

[0007] Furthermore, the limiting mechanism includes a limiting rod hinged to the side wall of the placement slot, and a plurality of evenly distributed limiting openings are opened on one side of the rotating block. A sliding fit is formed between the limiting rod and the inner wall of the limiting opening. The bottom of the limiting rod is fixedly connected to a limiting spring, and the limiting spring is fixedly connected to the side wall of the placement slot. The limiting rod is arranged to be rotated into the limiting opening. When the limiting rod is rotated into the limiting opening, the inner wall of the limiting opening limits the limiting rod, so that the rotating block can be fixedly operated and reversal of the rotating block can be avoided.

[0008] Furthermore, the inner walls at both ends of the limit opening are fixedly connected with fixing pads, and the fixing pads are made of rubber. The limit rod is in contact with the fixing pads. The setting of the fixing pads can increase the friction between the inner wall of the limit opening and the limit rod, so that the limit rod can be stably placed in the inner wall of the limit opening, and separation between the limit rod and the inner wall of the limit opening can be avoided.

[0009] Furthermore, both ends of the top of the adjusting block are fixedly connected to fixed plates, and a rotating shaft is rotatably connected between the two fixed plates on the same side through a bearing. The top of the rotating shaft is fixedly connected to a pressure rod, and the bottom of the rotating shaft is fixedly connected to a rotating plate. The rotating plate and the placement plate are hinged. The setting of the rotating shaft can rotate when the rotating plate rotates. The rotation of the rotating shaft can cause the pressure rod to rotate. The rotation of the pressure rod can cause the pressure plate to squeeze and tighten the side of the display screen body.

[0010] Furthermore, the placement plate is of a right-angle structure, and a pressure plate is hinged on one side of the pressure rod. The pressure plate can rotate when the placement plate is rotated downward, so that the side of the display screen body can be fixed.

[0011] Furthermore, a plurality of evenly distributed rotating grooves are provided on one side of the pressure plate, and a rotating ball is rotatably connected to the inner wall of the rotating groove. The setting of the rotating ball allows a rotating operation to be performed in the inner wall of the rotating groove. When the rotating ball contacts the side of the display screen body, it can roll on the side thereof, thereby providing a certain degree of protection for the frame of the display screen body.

[0012] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0013] 1. The utility model can make the double-headed threaded rod rotate by rotating the rotating block, and cooperate with the inner wall of the adjusting groove to limit the adjusting block. With the rotation of the double-headed threaded rod, the two adjusting blocks can slide in opposite directions on the inner wall of the adjusting groove. When the two adjusting blocks are close to each other, the display screen is placed on the placement plate through the pressure plate. When the display screen body presses the placement plate, the placement plate is forced to drive the rotating plate to rotate. The rotation of the rotating plate can make the pressure rod rotate through the rotating shaft. The rotation of the pressure rod can make the pressure plate press the upper side of the display screen body. At this time, the display screen body can be further fixed. Therefore, the staff only needs to rotate the rotating blocks in sequence to complete the installation, which reduces the labor intensity of the staff and can achieve the effect of improving the installation efficiency of the LED display screen.

[0014] 2. The utility model can rotate when the rotating plate rotates through the rotating shaft, and the rotation of the rotating shaft can make the pressure rod rotate. The rotation of the pressure rod can make the pressure plate squeeze and tighten the side of the display screen body. The pressure plate can rotate when the placement plate is rotated downward, so that the side of the display screen body can be fixed. The rotating ball can rotate in the inner wall of the rotating groove. When the rotating ball contacts the side of the display screen body, it can roll on the side, so as to protect the frame of the display screen body to a certain extent.

The bottom of the limit rod 8 is fixedly connected to the limit spring 10, and the limit spring 10 is fixedly connected to the side wall of the placement groove 20. The limit rod 8 can be rotated into the limit opening 9. When the limit rod 8 is rotated into the limit opening 9, the inner wall of the limit opening 9 limits the limit rod 8, so that the rotating block 6 can be fixed and the rotating block 6 can be prevented from reversing. The inner walls at both ends of the limit opening 9 are fixedly connected with fixed pads 11, and the fixed pads 11 are made of rubber. The limit rod 8 contacts with the fixed pads 11. The fixed pads 11 can increase the friction between the inner wall of the limit opening 9 and the limit rod 8, so that the limit rod 8 can be stably placed in the inner wall of the limit opening 9, and separation between the limit rod 8 and the inner wall of the limit opening 9 can be avoided.

[0023] like Figure 1 , Figure 2 and Figure 4The top ends of the adjustment block 4 shown are fixedly connected with fixed plates 12, and a rotating shaft 13 is rotatably connected between the two fixed plates 12 on the same side through a bearing, and a pressure rod 14 is fixedly connected to the top of the rotating shaft 13, and a rotating plate 15 is fixedly connected to the bottom of the rotating shaft 13. The rotating plate 15 is hinged with the placement plate 7, and can rotate when the rotating plate 15 rotates through the rotating shaft 13. The rotation of the rotating shaft 13 can make the pressure rod 14 rotate, and the rotation of the pressure rod 14 can make the pressure plate 16 squeeze and tighten the side of the display body 2, and the placement plate 7 is a right-angle structure, and a pressure plate 16 is hinged on one side of the pressure rod 14.
