[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0025] Reference Figure 1-Figure 6 , an efficient heat dissipation type liquid crystal display screen, comprising a screen body 1, a mounting groove is provided on the back of the screen body 1, a plurality of rotating shafts are horizontally and equidistantly mounted in the mounting groove, a fan blade 2 is fixedly sleeved on the rotating shaft, and a filter 3 is provided at the notch of the mounting groove;

[0026] The filter screen 3 is symmetrically provided with mounting openings on its surface, and a through opening is provided on the wall of the mounting opening. A spring rod 4 is horizontally rotatably installed in the mounting opening, and one end of the spring rod 4 passes through the through opening and is fixedly provided with a triangular locking block 5. The left and right groove walls of the mounting groove are both provided with locking grooves 6 for the locking block 5 to enter, and a pull plate 7 is fixedly sleeved on the spring rod 4;

[0027] When the filter screen 3 needs to be installed, first push the filter screen 3 into the notch of the installation groove, the inclined surfaces of the two locking blocks 5 will be against the wall of the installation opening, and under the action of the inclined surface pressure, the two spring rods 4 will shrink together until the filter screen 3 is completely moved into the notch, at which time the two locking blocks 5 will correspond to the positions of the two locking grooves 6 respectively, and the pressure force applied to the locking blocks 5 by the installation opening disappears, and the two locking blocks 5 will move and reset under the elastic potential energy of the two spring rods 4, and be inserted into the two locking grooves 6 respectively, thereby completing the locking of the filter screen 3. When the filter screen 3 needs to be removed, it is only necessary to pull the two pull plates 7 closer to each other, control the two spring rods 4 to shrink together, and make the two locking blocks 5 move out of the two locking grooves 6 respectively to release the lock of the filter screen 3, and then remove it. It is convenient and fast, and the removal and installation of the filter screen 3 can be completed quickly, avoiding the cumbersome steps of using screw and nut fixings, and improving the work efficiency of disassembling and assembling the filter screen 3.

[0028] A support assembly is provided on the back of the screen body 1, and the support assembly is used to support the screen body 1. The support assembly includes two rotating rods symmetrically installed horizontally on the back of the screen body 1, two gears 8 fixedly sleeved on the two rotating rods and two supporting rods 9. An L-shaped connecting rod is fixedly installed on the surface of the gear 8. The two supporting rods 9 are fixedly connected to one end of the two connecting rods respectively. A driving assembly is provided on the back of the screen body 1. The driving assembly is used to control the relative rotation of the two rotating rods. The driving assembly includes a threaded rod 10, a slider 11 threadedly sleeved on the threaded rod 10 and two rack rods 12. A mounting plate is fixedly installed on the back of the screen body 1. The threaded rod 10 is vertically rotatably installed on the lower surface of the mounting plate. The slider 11 is limited in rotation by a limiting component. The two rack rods 12 are fixedly installed on the left and right side walls of the slider 11 through connecting rods, and are respectively meshed with the two gears 8. The slider 11 is limited in rotation by a limiting component. The limiting component includes a limiting groove 13 vertically opened on the back of the screen body 1 and a limiting block 14 fixedly installed on the surface of the slider 11, and one end of the limiting block 14 is slidably configured in the limiting groove 13;

[0029] By rotating the threaded rod 10, the slider 11 threadedly connected to the threaded rod 10 will move vertically with the two rack rods 12 under the limiting action of the limiting block 14 and the limiting groove 13. When the two rack rods 12 move, the two gears 8 respectively meshing with the two rack rods 12 will rotate relative to each other, so that the two support rods 9 will also rotate with the two gears 8 respectively, and the distance between the two support rods 9 can be adjusted. When the distance between the two support rods 9 becomes smaller, the height of the screen body 1 will increase. When the distance between the two support rods 9 becomes larger, the height of the screen body 1 will decrease, and the height of the supported screen body 1 is no longer fixed, thereby improving practicality.

[0030] The surface of the support rod 9 is bonded with an anti-skid layer made of rubber. The rubber anti-skid layer has good elasticity and viscosity, which can increase the friction on the surface of the support rod 9 and improve the stability of the supporting screen body 1.

[0031] When the filter screen 3 is to be installed, the filter screen 3 is first pushed into the notch of the installation slot, and the inclined surfaces of the two locking blocks 5 will be against the wall of the installation slot. Under the pressure of the inclined surfaces, the two spring rods 4 will shrink together until the filter screen 3 is completely moved into the notch. At this time, the two locking blocks 5 will correspond to the positions of the two locking slots 6 respectively, and the pressure applied by the installation slot to the locking blocks 5 disappears, and the two locking blocks 5 will move and reset under the elastic potential energy of the two spring rods 4, and insert into the two locking slots 6 respectively, thereby completing the locking of the filter screen 3. When the filter screen 3 needs to be removed, it is only necessary to pull the two pull plates 7 closer to each other, control the two spring rods 4 to shrink together, and make the two locking blocks 5 move out of the two locking slots 6 respectively to release the lock of the filter screen 3, and then remove it. It is convenient and fast, and the removal and installation of the filter screen 3 can be completed quickly, avoiding the cumbersome steps of using screw and nut fixings, and improving the working efficiency of disassembling and assembling the filter screen 3.

[0032] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
