Technical Field

[0001] This utility model relates to the field of display screen brackets, specifically a quick-release structure for adjusting display screen brackets. Background Technology

[0002] With the widespread use of computers, workstations, and other devices, monitors have become an indispensable part of people's work and life. To achieve a better viewing experience and ergonomic usage posture, height-adjustable monitor stands have become widely used. Existing height-adjustable monitor stands typically use balancing components such as springs or gas springs to counteract the monitor's own weight, allowing users to easily raise and lower the monitor.

[0003] However, this type of display bracket has a relatively complex internal structure, high production cost, and poor locking reliability. Therefore, there is an urgent need for a new type of quick-release structure that can quickly release and lock the limit switch when adjusting the height of the display screen, and is simple to operate, has a stable lock, and is compact and durable. Utility Model Content

[0004] The purpose of this invention is to provide a quick-release structure for adjusting a display screen bracket, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-release structure for adjusting a display screen bracket, comprising: a base, a column fixed to the top of the base, a sleeve fitted on the column, a gap in the sleeve, a first clamping plate and a second clamping plate fixed on the sleeve, a screw hole in the first clamping plate, a pin connected to the screw hole by a threaded connection at one end of the pin, the other end of the pin passing through a through hole and fixed to a handle mounting plate, a push plate fitted on the pin, a handle rotatably connected to the handle mounting plate, and a through hole in the second clamping plate.

[0006] Preferably, a connecting shaft is inserted and fixed on the handle mounting plate. The connecting shaft has a round rod structure, and both ends of the connecting shaft extend from the handle mounting plate and are movably inserted into the handle.

[0007] Preferably, the handle has a relaxed state indicator groove and a clamping state indicator groove. The part of the handle that contacts the handle mounting plate has an elliptical plate structure. The end of the handle with the relaxed state indicator groove has a smaller diameter, and the end with the clamping state indicator groove has a larger diameter.

[0008] Preferably, a washer is fitted on the pin. The washer has a circular plate structure, with one end of the washer abutting against the push plate and the other end of the washer abutting against the second clamping plate.

[0009] Preferably, a cross arm is rotatably connected to the sleeve, and a display screen mounting plate is rotatably connected to the other end of the cross arm.

[0010] Preferably, a cable hub is fitted onto the cross arm.

[0011] Preferably, a rubber sleeve is fitted onto the column, and the rubber sleeve is movably connected to the sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model proposes a quick-release structure for adjusting a display screen bracket. When the height of the display screen needs to be adjusted, the handle is rotated in the opposite direction with the axis of the connecting shaft as the center line. The end of the handle with the relaxation state indicator groove has a smaller diameter, so that the friction between the rubber sleeve and the column is restored to a state slightly greater than the weight of the display screen installed on the display screen bracket. Then, the display screen can be lifted or pressed down by hand to adjust the height of the display screen. After adjusting to the desired height, the handle is rotated again to limit the display screen to that height. This quick-release structure is simple to operate, locks firmly, has a compact and durable structure, and is inexpensive. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Example 1: Please refer to Figures 1-6 This utility model provides a technical solution: a quick-release structure for adjusting a display screen bracket, comprising: a base 20, a column 1 fixed to the top of the base 20, a sleeve 2 sleeved on the column 1, a gap 3 on the sleeve 2, a first clamping plate 4 and a second clamping plate 14 fixed on the sleeve 2, a screw hole 5 on the first clamping plate 4, a pin 6 threadedly connected to the screw hole 5, the other end of the pin 6 passing through a through hole 15 and fixed to a handle mounting plate 7, a push plate 13 sleeved on the pin 6, and a handle 9 rotatably connected to the handle mounting plate 7, the through hole 1... 5 is provided on the second clamping plate 14; a rubber sleeve 12 is fitted on the column 1, and the rubber sleeve 12 is movably connected to the sleeve 2; a connecting shaft 8 is inserted and fixed on the handle mounting plate 7, the connecting shaft 8 is a round rod structure, and both ends of the connecting shaft 8 extend from the handle mounting plate 7 and are movably inserted into the handle 9; the handle 9 is provided with a relaxed state indicator groove 10 and a clamping state indicator groove 11, the part of the handle 9 that contacts the handle mounting plate 7 is an elliptical plate structure, the end of the handle 9 with the relaxed state indicator groove 10 has a smaller diameter and the end with the clamping state indicator groove 11 has a larger diameter.

[0017] The pin 6 is passed through the through hole 15 and screwed into the screw hole 5 to a certain extent, so that the gap 3 still has a relatively large width. Then, the rubber sleeve 12 is placed in the inner ring of the sleeve 2, and the column 1 is inserted into the sleeve 2. Then, the pin 6 is further screwed in, so that the pin 6 is inserted into the screw hole 5 a longer distance. This causes the handle 9 to move towards the first clamping plate 4. The movement of the handle 9 pushes the push plate 13 towards the first clamping plate 4, and pushes the second clamping plate 14 towards the first clamping plate 4, so that the width of the gap 3 is reduced, and the inner ring of the sleeve 2 and the rubber sleeve 12 are gradually clamped on the column 1. The rubber sleeve 12 has a large roughness, so that a large frictional force is generated between the rubber sleeve 12 and the column 1. This frictional force is slightly greater than the weight of the display screen installed on the display screen bracket, which can keep the display screen at a certain height.

[0018] When the display screen needs to be fixed at a certain height, rotate the handle 9 around the axis of the connecting shaft 8 so that the end of the handle 9 with the clamping status indicator groove 11 contacts the push plate 13. The diameter of the end of the handle 9 with the clamping status indicator groove 11 is longer, so that the handle 9 pushes the push plate 13 further towards the first clamping plate 4. This further compresses the width of the gap 3, resulting in greater friction between the rubber sleeve 12 and the column 1, thus fixing the display screen at a certain height. When the height of the display screen needs to be adjusted, rotate the handle 9 in the opposite direction around the axis of the connecting shaft 8. The diameter of the end of the handle 9 with the relaxation status indicator groove 10 is smaller, so that the friction between the rubber sleeve 12 and the column 1 returns to a state slightly greater than the weight of the display screen mounted on the display screen bracket. Then, lift or press down the display screen to adjust its height. After adjusting to the desired height, rotate the handle 9 again to fix the display screen at that height. This quick-release structure is simple to operate, securely locked, compact and durable, and inexpensive.

[0019] Example 2: Based on Example 1, in order to reduce wear between the push plate 13 and the second clamping plate 14, a washer 16 is fitted on the pin 6. The washer 16 has a circular plate structure, with one end of the washer 16 abutting against the push plate 13 and the other end of the washer 16 abutting against the second clamping plate 14.

[0020] A shim 16 is provided between the push plate 13 and the second clamping plate 14. The shim 16 is soft and separates the push plate 13 from the second clamping plate 14, thereby preventing wear between the push plate 13 and the second clamping plate 14.

[0021] Example 3: Based on Example 2, in order to achieve the orientation adjustment of the display screen, a horizontal arm 17 is rotatably connected to the sleeve 2, and a display screen mounting plate 19 is rotatably connected to the other end of the horizontal arm 17.

[0022] The display mounting plate 19 has screw holes, which correspond to the screw holes reserved on the display screen. After the screws are passed through the screw holes of the display mounting plate 19, they are tightened into the screw holes of the display screen, thereby installing the display screen onto the display mounting plate 19. The orientation of the display screen can be adjusted by rotating the horizontal arm 17 and the display mounting plate 19 and rotating the sleeve 2 and the horizontal arm 17.

[0023] Example 4: Based on Example 3, in order to organize the wire harness, a wire hub 18 is fitted on the cross arm 17.

[0024] Multiple wires often need to be plugged into the display screen. Before plugging them in, pass the wires through the hub 18 and then plug them in. This will allow the wires to be concentrated in the hub 18, making it easier to organize the wires.

[0025] In actual use, the column 1 is vertically installed on the table via the base 20. The pin 6 is passed through the through hole 15 and screwed into the screw hole 5 to a certain extent, so that the gap 3 still has a relatively large width. Then, the rubber sleeve 12 is placed in the inner ring of the sleeve 2, and the column 1 is inserted into the sleeve 2. Then, the pin 6 is further screwed in, so that the pin 6 is inserted into the screw hole 5 a longer distance. This causes the handle 9 to move towards the first clamping plate 4. The movement of the handle 9 pushes the push plate 13 towards the first clamping plate 4, and pushes the second clamping plate 14 towards the first clamping plate 4, so that the width of the gap 3 is reduced, and the inner ring of the sleeve 2 and the rubber sleeve 12 are gradually clamped on the column 1. The rubber sleeve 12 has a large roughness, so that a large frictional force is generated between the rubber sleeve 12 and the column 1. This frictional force is slightly greater than the weight of the display screen installed on the display screen bracket, which can keep the display screen at a certain height.

[0026] When the display screen needs to be fixed at a certain height, rotate the handle 9 around the axis of the connecting shaft 8 so that the end of the handle 9 with the clamping status indicator groove 11 contacts the push plate 13. The diameter of the end of the handle 9 with the clamping status indicator groove 11 is longer, so that the handle 9 pushes the push plate 13 further towards the first clamping plate 4. This further compresses the width of the gap 3, resulting in greater friction between the rubber sleeve 12 and the column 1, thus fixing the display screen at a certain height. When the height of the display screen needs to be adjusted, rotate the handle 9 in the opposite direction around the axis of the connecting shaft 8. The diameter of the end of the handle 9 with the relaxation status indicator groove 10 is smaller, so that the friction between the rubber sleeve 12 and the column 1 returns to a state slightly greater than the weight of the display screen mounted on the display screen bracket. Then, lift or press down the display screen to adjust its height. After adjusting to the desired height, rotate the handle 9 again to fix the display screen at that height. This quick-release structure is simple to operate, securely locked, compact and durable, and inexpensive.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
