Technical Field

[0001] The utility model belongs to the technical field of display screens, and particularly relates to a display screen bracket. Background Art

[0002] A display screen generally refers to a monitor, which is an I / O device of a computer, that is, an output device. It is a display tool that displays certain electronic files on the screen through a specific transmission device. It can be divided into a cathode ray tube monitor, a plasma monitor, and a liquid crystal monitor.

[0003] During the use of a monitor, a bracket needs to be equipped. Most of the existing display screen brackets can perform pitch angle adjustment and lifting adjustment. At the same time, the display screen and the bracket are directly assembled by bolts. The bolt assembly is relatively cumbersome, and after being screwed multiple times, it is easy to cause thread failure, resulting in the problem of loose installation of the display screen, and there are certain limitations in use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] Please refer to Figure 1-8, the utility model provides a display screen bracket, which includes a base 1. A rotating shaft 1 is rotatably installed on the upper surface of the base 1. A locking rod 3 is movably arranged on the outer surface of the rotating shaft 1. A plurality of locking grooves for inserting the locking rod 3 are formed on the upper surface of the base 1. The top end of the rotating shaft 1 is fixedly installed with a mounting seat 4. A rotating shaft 2 is rotatably installed on the mounting seat 4. A fixing seat 6 is fixedly installed on the outer surface of the rotating shaft 2. A housing 7 is fixedly installed on the side surface of the fixing seat 6. A first push plate 8 is slidably installed on the lower surface of the housing 7. The top end of the first push plate 8 is movably installed with a first hinge seat 12. The first push plates 9 are slidably installed on the left and right side surfaces of the housing 7. A second hinge seat 13 is fixedly installed at the opposite ends of the two first push plates 9. A hinge arm 14 is hingedly installed between the first hinge seat 12 and the second hinge seat 13. A first clamping plate 10 is fixedly installed at the bottom end of the first push plate 8 and at the opposite ends of the two first push plates 9. A second clamping plate 11 is movably arranged on the first clamping plate 10.

[0034] A fixing block 26 is fixedly installed on the outer surface of the rotating shaft 1. The locking rod 3 is slidably installed on the fixing block 26 and a fixing ring 27 is fixedly installed on the outer surface of the locking rod 3. A fourth spring 28 is fixedly installed between the fixing block 26 and the fixing ring 27. The fixing block 26 is used in cooperation with the fixing ring 27 and the fourth spring 28. When the locking rod 3 disengages from the locking groove, the fourth spring 28 will deform. Therefore, the elasticity of the fourth spring 28 can be used to drive the locking rod 3 to quickly insert into the locking groove, improving the convenience of the locking operation.

[0035] An arc-shaped slideway is formed on the mounting seat 4 and the arc-shaped slideway is arranged coaxially with the rotating shaft 2. A first fixing screw 15 is fixedly installed on the side surface of the fixing seat 6. The first fixing screw 15 passes through the arc-shaped slideway and a first nut 16 is threadedly installed on the outer surface of the first fixing screw 15. The first nut 16 is arranged in a fitting manner on the side surface of the mounting seat 4. By using the first fixing screw 15 in cooperation with the first nut 16, when the mounting seat 4 and the fixing seat 6 rotate relative to each other to adjust the pitching angle of the display screen, the first nut 16 can be screwed onto the first fixing screw 15 to achieve extrusion and fixation, improving the stability of the locking effect and avoiding loosening.

[0036] A guide block 17 is fixedly installed at the end of the first hinge seat 12. A guide rod 18 is slidably installed on the guide block 17. The guide rod 18 is fixed on the inner wall of the housing 7. A first spring 19 is fixedly installed between the inner wall of the housing 7 and the guide block 17. The guide block 17 and the guide rod 18 are used in cooperation with the first spring 19. When the first clamping plate 10 at the lower position moves downward to clamp the display screen, the first spring 19 deforms. Therefore, when the display screen is removed, the elasticity of the first spring 19 can be used to drive the first clamping plate 10 to quickly reset, improving the convenience of the operation.

[0037] On one side of the second clamping plate 11 facing the first clamping plate 10, a sliding block 20 is fixedly installed. The sliding block 20 is slidably installed on the inner wall of the sliding groove opened on the surface of the first clamping plate 10. The sliding block 20 is used in cooperation with the sliding groove, which can support and guide the sliding direction of the second clamping plate 11 and improve the movement stability.

[0038] A second fixing screw 21 is fixedly installed on the side of the sliding block 20. A through hole for the second fixing screw 21 to pass through is opened on the first clamping plate 10. The second fixing screw 21 passes through the through hole and is threadedly installed with a second nut 22. The second nut 22 is attached to the side of the first clamping plate 10. When the second nut 22 is screwed onto the second fixing screw 21, it can drive the sliding block 20 to drive the second clamping plate 11 to move, thereby realizing the clamping of the display screen.

[0039] A plug rod 24 is inserted into the first hinge seat 12. A third spring 25 is fixedly installed between the plug rod 24 and the first hinge seat 12. A number of insertion holes for the plug rod 24 to be inserted into are opened on the first push plate 8. An operation channel is opened on the side of the housing 7. The third spring 25 is used in cooperation with the plug rod 24, which can adjust and lock the positions of the first push plate 8 and the first hinge seat 12. The locking structure is simple and the operation is convenient.

[0040] A second spring 23 is sleeved outside the second fixing screw 21. The two ends of the second spring 23 are respectively fixedly connected to the side of the sliding block 20 and the inner wall of the sliding groove. The arrangement of the second spring 23 can quickly drive the second clamping plate 11 to reset when the second nut 22 unscrews the second fixing screw 21, improving the operation convenience.

[0041] When in use, when installing the display screen, first adjust the initial position of the first clamping plate 10 at the lower position according to the size specification of the display screen. When adjusting, pull the insertion rod 24 so that the insertion rod 24 disengages from the jack, release the locking of the first hinge seat 12 and the first pushing plate 8, hold the lower first clamping plate 10 and move it up and down to adjust the initial position. After adjustment, release the insertion rod 24, and use the elasticity of the third spring 25 to drive the insertion rod 24 to reset and insert into the jack to realize the locking of the first hinge seat 12 and the first pushing plate 8. Then place the display screen on the first clamping plate 10 at the lower position. Due to the gravity of the display screen, it will drive the first clamping plate 10 at the lower position to move downward, and then drive the first hinge seat 12 to move downward through the first pushing plate 8. Under the action of the first hinge seat 12, the first hinge arm 14 and the second hinge arm 14, the two first clamping plates on the left and right sides are driven to approach each other relatively, realizing the side clamping of the display screen. Then screw on the second nut 22 so that when the second nut 22 is screwed, it will drive the second fixing screw 21 to move, and then drive the second clamping plate 11 to approach the display screen through the sliding block 20, thereby realizing the front clamping of the display screen. When the display screen is in use, it can be adjusted for horizontal rotation. When adjusting, pull up the locking rod 3 so that the locking rod 3 disengages from the locking groove, and then rotate the first rotating shaft 2 to realize the horizontal rotation adjustment. After adjustment, release the locking rod 3, and use the elasticity of the fourth spring 28 to drive the locking rod 3 to reset and insert into the locking groove. It can also be adjusted for the pitching angle. When adjusting, unscrew the first nut 16 to release the locking of the fixing seat 6 and the mounting seat 4, and use the second rotating shaft 5 to realize the pitching angle adjustment. After adjustment, screw on the first nut 16 to realize the extrusion fixation.
