Description
Technical Field
[0001] The utility model relates to the technical field of screen angle adjustment mechanisms, in particular to a screen pitch angle adjustment device. Background Art
[0002] The screen pitch angle refers to the tilt angle of the monitor screen relative to the horizontal plane. It is usually used to adjust the viewing comfort and visual effects of the screen. There are some differences in the pitch angle adjustment of monitors of different brands and models.
[0003] Traditional pitch angle adjustment devices generally use a snap-on fixation, which results in jump-like adjustments when adjusting the pitch angle of the screen, and some subtle angles cannot be adjusted. At the same time, when it is necessary to adjust to the vertical angle, the adjustment device is prone to interfere with the screen and its circuits, causing the adjustment device to fail.
[0004] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a screen pitch angle adjustment device to solve the above problems.
[0005] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solution of the present invention and facilitating the understanding of those skilled in the art. It cannot be assumed that the above contents are well known to those skilled in the art simply because they are explained in the background technology of the present invention. Utility Model Content
[0006] In order to overcome the above-mentioned deficiencies in the prior art, the purpose of the present invention is to disclose a screen pitch angle adjustment device for solving the problem that traditional screens are difficult to continuously adjust the pitch angle.
[0007] The utility model discloses a screen pitch angle adjustment device, comprising an arc-shaped adjustment plate, a locking assembly and an external fixing column, wherein:
[0008] The front and rear sides of the arc adjustment plate are the screen mounting surface and the arc adjustment surface respectively. The screen mounting surface is used to fix the screen. The arc adjustment surface is an arc surface that bends vertically away from the screen mounting surface. The arc adjustment surface is provided with a guide groove along its arc direction.
[0009] The locking assembly includes a base, an adjusting bolt, a spring and a locking block. The front end of the adjusting bolt is angled with the horizontal direction and passes through the spring, the base and the guide groove in sequence and is locked on the arc adjustment plate through the threaded hole on the locking block. The rear end of the adjusting bolt is provided with a gasket, the front end of the spring abuts against the base, and the rear end of the spring abuts against the gasket; the spring provides elastic force between the gasket and the base, so that the adjusting bolt drives the locking block to lock the arc adjustment plate on the base, and the compression amount of the spring is changed by rotating the adjusting bolt to adjust the extrusion force of the locking block on the arc adjustment plate, thereby adjusting the friction resistance of the arc adjustment plate to move up and down, and using the curvature of the arc adjustment plate to change the pitch angle of the screen during the up and down movement.
[0010] The external fixing column is fixedly connected to the base, and the base is fixed to a wall or a bracket through the external fixing column.
[0011] The preferred technical solution: the base includes an upper base and a lower base, the lower end of the upper base is provided with a seating groove, the upper end of the seating groove is connected to a guide channel for the adjusting bolt to pass through, the spring and the gasket are arranged in the seating groove, the lower base is fixed to the lower end of the upper base, and the upper end of the lower base blocks the opening of the seating groove, so that the spring and the gasket move in the area enclosed by the lower base and the seating groove, avoiding external interference and preventing the adjusting bolt from retreating too much and completely separating from the locking block, thereby preventing the arc adjustment plate and the screen from falling off.
[0012] Preferred technical solution: the upper end of the external fixing column passes through the upper base and is fixedly connected to the outside, the lower end of the external fixing column is provided with a limit block, the upper end surface of the lower base is abutted against the lower end of the limit block, and the external fixing column is clamped and installed by the lower base and the upper base, which is convenient for quick disassembly.
[0013] Preferred technical solution: The locking assembly also includes an adjusting rod, the front end of which passes through the lower base and is transmission-connected to the rear end of the adjusting bolt. The adjusting bolt is rotated by the adjusting rod to increase the turning torque and reduce the difficulty of rotating the adjusting bolt.
[0014] Preferred technical solution: The upper base and the lower base are connected by fastening screws, which has good connection stability and is easy to disassemble and assemble.
[0015] Preferred technical solution: A positioning groove is provided on the upper base, which is fitted and connected to the arc-shaped adjustment surface. The upper end opening of the guide channel is set at the bottom of the positioning groove. The positioning groove increases the contact area between the upper base and the arc-shaped adjustment surface, thereby increasing the friction between the upper base and the arc-shaped adjustment surface, thereby preventing the arc-shaped adjustment surface from sliding when in a locked state, and improving the stability of the arc-shaped adjustment plate and the screen above it.
[0016] Preferred technical solution: baffles are provided on both sides of the positioning groove, which limit the rotation of the locking block to prevent the locking block from rotating when the adjusting bolt rotates.
[0017] Preferred technical solution: The gasket is a bowl-shaped gasket. The bowl-shaped gasket has a retreat-stopping effect, increases the force-bearing area, can better disperse the pressure, avoid local stress concentration, and thus improve overall stability and durability.
[0018] Due to the application of the above technical solution, the present invention has the following beneficial effects compared with the prior art:
[0019] The utility model discloses a screen angle adjustment device, which provides locking force for a locking assembly through a gasket and a spring, so that the locking block can lock the arc-shaped adjustment surface on the base at any position in the up and down directions, and utilizes the arc surface of the arc-shaped adjustment surface to adjust the pitch angle of the screen when the arc-shaped adjustment surface moves up and down, so that the pitch angle of the screen can be continuously and finely adjusted; the adjustment bolt is set at an angle to the horizontal direction to avoid the direction of the gravity of the screen being consistent with the direction of the friction force at the locking block, thereby improving the stability of the screen installation; the elastic force is used as the locking force, so that the friction force between the locking block and the arc-shaped adjustment surface changes gradually when adjusting, thereby avoiding damage to the screen due to rapid imbalance; the arc-shaped adjustment plate is used for transfer to avoid interference with the locking assembly when the screen is adjusted to a vertical angle.

[0031] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0032] Example 1:
[0033] like Figure 1 and Figure 2 As shown, the present invention discloses a screen pitch angle adjustment device, including an arc-shaped adjustment plate 1, a locking assembly 2 and an external fixing column 3. The main components of the present invention will be described in detail below:
[0034] like Figure 1 、 Figure 2 and Figure 3 As shown, the front and rear sides of the arc-shaped adjustment plate 1 are respectively a screen mounting surface 11 and an arc-shaped adjustment surface 12. The screen mounting surface 11 is used to fix the screen, and the arc-shaped adjustment surface 12 is used to connect with the locking assembly 2. The arc-shaped adjustment surface 12 is provided with a guide groove 12a along its arc surface direction.
[0035] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the locking assembly 2 includes a base 21, an adjusting bolt 22, a spring 23 and a locking block 24. The front end of the adjusting bolt 22 is angled with the horizontal direction and passes through the spring 23, the base 21 and the guide groove 12a in sequence and is locked on the arc-shaped adjustment plate 1 through the threaded hole on the locking block 24. The rear end of the adjusting bolt 22 is provided with a gasket 221; the front end of the spring 23 abuts against the base 21, and the rear end of the spring 23 abuts against the gasket 221. The gasket 221 is a bowl-shaped gasket used to ensure the rear end limiting function of the spring 23.
[0036] like Figure 1 and Figure 2 As shown, the external fixing column 3 is fixedly connected to the base 21 and is used to fix the base 21 and fix it to an external wall or bracket.
[0037] refer to Figure 1 、 Figure 2、 Figure 3 and Figure 4 As shown, the usage and principle of the present invention are as follows: when the pitch angle of the screen needs to be adjusted, the adjusting bolt 22 is unscrewed backward to reduce the compression of the spring 23, thereby reducing the extrusion force of the locking block 24 on the arc-shaped adjustment surface 12, and thus reducing the friction between the locking block 24 and the arc-shaped adjustment surface 12, so that the arc-shaped adjustment plate 1 can be pushed to move up and down along the setting direction of the guide groove 12a. Due to the arc surface design of the arc-shaped adjustment surface 12, the pitch angle of the arc-shaped adjustment plate 1 changes during its up and down movement, thereby driving the pitch angle of the screen on the screen mounting surface 11 to change; in this process, the spring 23 can be squeezed by rotating the adjusting bolt 22, and the locking block 24 can be used to lock the arc-shaped adjustment plate 1 at any adjustment angle, so that the pitch angle of the screen on the arc-shaped adjustment plate 1 can be continuously adjusted; at the same time, since the screen and the locking assembly 2 are connected through the arc-shaped adjustment plate 1, the possibility of interference between the screen and the locking assembly 2 when the screen is set vertically is avoided.
[0038] Example 2:
[0039] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in order to facilitate the disassembly and assembly of the screen pitch angle adjustment device, the base 21 includes an upper base 211 and a lower base 212 , and the upper base 211 and the lower base 212 are connected by fastening screws 213 . The lower end of the upper base 211 is provided with a seating groove 211a, and the upper end of the seating groove 211a is connected to a guide channel 211b for the adjusting bolt 22 to pass through. The spring 23 and the gasket 221 are arranged in the seating groove 211a, and the lower base 212 is fixed to the lower end of the upper base 211, and the upper end of the lower base 212 blocks the opening of the seating groove 211a; the upper end of the external fixing column 3 passes through the upper base 211 and is fixedly connected to the outside, and the lower end of the external fixing column 3 is provided with a limit block 31, and the upper end surface of the lower base 212 is abutted against the lower end of the limit block 31. This design limits and fixes the fastening screw 213 and the external fixing column 3 through the lower base 212, making it more convenient to disassemble and assemble.
[0040] Example 3:
[0041] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in order to facilitate the adjustment of the adjusting rod 25, an adjusting rod 25 is provided on the locking assembly 2. The front end of the adjusting rod 25 passes through the lower base 212 and is transmission-connected with the rear end of the adjusting bolt 22. The adjusting rod 25 is used to adjust the adjusting bolt 22, thereby increasing the adjustment torque and reducing the difficulty of adjustment.
[0042] Example 4:
[0043] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in order to improve the connection stability between the arc-shaped adjustment plate 1 and the locking assembly 2, a positioning groove 211c is provided on the upper base 211, which is closely connected to the arc-shaped adjustment surface 12. The upper end opening of the guide channel 211b is set at the bottom of the positioning groove 211c, and is connected to the arc-shaped adjustment surface 12 through the positioning groove 211c, thereby increasing the contact area between the two and increasing the connection friction force when the extrusion force remains unchanged, thereby ensuring the stability of the connection.
[0044] Embodiment 5:
[0045] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, in order to prevent the locking block 24 from rotating along with the adjusting bolt 22, a blocking bar 211d is provided on both sides of the positioning groove 211c. The blocking bar 211d blocks and limits both sides of the locking block 24 to ensure that it does not rotate along with the adjusting bolt 22.
[0046] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
