Description

Technical Field

[0001] The utility model relates to the field of liquid crystal display screens, in particular to a large LED liquid crystal display screen. Background Technique

[0002] With the development of liquid crystal technology, large-size liquid crystal display screens are widely used in outdoor advertising, conference video or sports venue video playback, and popular science publicity, etc.

[0003] In the existing display screen, light guide strips are respectively arranged on the left and right sides and the top side of the electrical cavity of the frame housing. These light guide strips can reflect the residual light scattered from the side of the light guide plate and then re-enter the light guide plate, and are emitted from the light-emitting surface of the light guide plate, improving the light flux emitted on the light guide plate.

[0004] However, when the existing large LED liquid crystal display screen is installed indoors or outdoors on high-rise buildings, due to the large occupied area of the LED display screen, it cannot be transported upward by the elevator or stairs inside the building, and it needs to be lifted upward by using hoisting equipment from the outside of the building. During the hoisting process, binding ropes are needed to bind and position the display screen. However, due to the cross-intercepting effect between the binding ropes and the display screen, there is no completely mutual fixing effect. Therefore, during the hoisting process, due to strong side winds at high altitudes, the suspension ropes swing, affecting the stability of the hoisting and lifting. If the swing amplitude is too large, the display screen will collide and be damaged. Content of the Utility Model

[0005] The purpose of the utility model is to provide a large LED liquid crystal display screen, which is used to solve the problem that when the existing large LED liquid crystal display screen is installed indoors or outdoors on high-rise buildings, due to the large occupied area of the LED display screen, it cannot be transported upward by the elevator or stairs inside the building, and it needs to be lifted upward by using hoisting equipment from the outside of the building. During the hoisting process, binding ropes are needed to bind and position the display screen. However, due to the cross-intercepting effect between the binding ropes and the display screen, there is no completely mutual fixing effect. Therefore, during the hoisting process, due to strong side winds at high altitudes, the suspension ropes swing, affecting the stability of the hoisting and lifting. If the swing amplitude is too large, the display screen will collide and be damaged.

[0006] Therefore, the utility model provides a large LED liquid crystal display screen, which includes a screen body, a protection mechanism and a hoisting mechanism. Quick-disassembly protection mechanisms are arranged at the upper and lower ends of the screen body. Outer plates are installed on the outer walls on both sides of the screen body, and a hoisting mechanism for quickly installing the suspension ropes is arranged on the upper side of the outer plates.

[0007] Preferably, the protection mechanism includes a top plate. A slot is formed in the top plate. A plug board is inserted into the slot. A central groove is formed inside the front end of the plug board. A first bevel gear is installed on the vertical inner wall of the central groove. A knob is connected to the outer end of the first bevel gear. Second bevel gears are installed on the inner walls on both sides of the central groove. Chutes are formed outside both ends of the central groove. A screw rod is installed inside the front end of the chute. A sleeve plate is sleeved on the outer wall of the screw rod. A clamping plate is installed on the lateral outside of the sleeve plate. Card slots are formed on both sides of the slot.

[0008] Preferably, the hoisting mechanism includes an embedded groove. An embedded board is inserted into the embedded groove. Inner grooves are formed inside the front and rear sides of the embedded board. Inner plates are slidably installed inside the inner grooves. A fixing plate is installed on the side wall at the lower end of the inner plate. Fixing grooves are formed on the front and rear sides of the embedded groove. A hydraulic rod is installed inside the upper end of the inner groove. A spring is sleeved on the outer wall of the hydraulic rod. A pressing plate is sleeved on the outer wall of the spring.

[0009] Preferably, the cross-sectional dimension of the clamping plate matches the cross-sectional dimension of the card slot.

[0010] Preferably, the first bevel gear meshes with the second bevel gear.

[0011] Preferably, the cross-sectional dimension of the fixing plate matches the cross-sectional dimension of the fixing groove.

[0012] Preferably, one end of the pressing plate is connected to the spring, and the other end of the spring is connected to the side wall of the hydraulic rod.

[0013] In the present utility model, when it is necessary to hoist a large LED liquid crystal display screen, the pressing plates on the front and rear sides of the embedded board with the connecting belt are pressed inward, so that they move towards the direction of the hydraulic rod, squeezing the spring to generate potential energy. The inner plate moves inside the inner groove to drive the fixing plate to move towards the inside of the inner groove. The embedded board is inserted downward into the embedded groove. The pressure on the pressing plate is released, and the spring releases the potential energy to push the pressing plate outward, driving the inner plate together with the fixing plate to move outward, so that the fixing plate is inserted into the aligned fixing groove to complete the quick fixing of the embedded board, so as to facilitate the quick, firm and symmetrical connection of the connecting belt for hoisting, bringing convenience to the subsequent hoisting operation. Before hoisting, the plug board is inserted backward into the slot in the top plate, and the knob is twisted to drive the first bevel gear to rotate. The meshing drives the second bevel gear to rotate, driving the connected screw rod to rotate. The meshing drives the sleeve plate to slide outward in the chute, driving the clamping plate at the outer end to insert into the aligned card slot, and the shock-absorbing strips made of rubber can be respectively installed on the upper and lower sides of the screen body to protect the protruding front edge of the screen body, improving the safety of the display screen during the hoisting process.
