Description

Technical Field

[0001] This invention relates to the field of angle adjustment, and more particularly to an angle adjustment device. Background Technology

[0002] In practical use, easels, display boards, and other similar products often require adjustment devices to assist in angle adjustment for better performance. Since these products need to be adjusted multiple times during use, the angle adjustment device should meet the following requirements to facilitate its operation: First, it should be easy to disassemble and install for convenient use; second, it should have good fixing properties, locking securely after adjustment; third, it should be easy to assemble, facilitating production and reducing costs; and finally, the adjustment range should meet usage needs as much as possible.

[0003] Angle adjustment devices have a wide range of applications. Patent CN201920078901.0 proposes a light angle adjustment device that uses two electro-hydraulic push rods to move a support plate horizontally, thereby adjusting the angle by driving a telescopic rod. While numerous existing angle adjustment devices exist, they all have unavoidable drawbacks when used with easels and display panels. For example, using an electrically driven rotating mechanism for angle adjustment results in high costs and heavy, less flexible components. Using a butterfly screw adjustment method can lead to loosening of the connection between the easel / display panel and the screw, resulting in instability and affecting usability. Therefore, designing a stable, convenient, and cost-effective angle adjustment device suitable for easels and display panels is essential. Summary of the Invention

[0052] Furthermore, pointer 13 and angle dial 6.

[0053] With this technical solution, since the second tube 42 can be adjusted by rotating the adjustment rod 2, the pointer 13 and the angle disk 6 can be prevented from colliding.

[0054] Furthermore, both the first end buckle 51 and the second end buckle 52 are snapped and fixed to the second tube body 42.

[0055] With this technical solution, both the first end buckle 51 and the second end buckle 52 are snapped and fixed to the second tube body 42, and reinforced by screw connection.

[0056] Working principle: The angle adjustment device is composed of a central tube 4, a connecting frame 1, a clamping assembly 3, a locking adjustment rod 2, and an end buckle. The drawing board and display board are fixed on the connecting frame 1. The connecting frame 1 can be configured with connecting assemblies according to actual usage needs, thus facilitating the installation and removal of the drawing board and display board. The connecting frame 1 is fixed and locked by the clamping assembly 3. The clamping state of the clamping assembly 3 can be controlled by adjusting the locking adjustment rod 2. After the clamping assembly 3 is released from its fixed state, the connecting frame 1 can be rotated using the rotating adjustment rod 12, thereby adjusting the drawing board and display board fixed on the connecting frame 1. The adjustment methods of the locking adjustment rod 2 and the rotating adjustment rod 12 are simple and convenient, making it easy to use in daily life.
