A limiting fit angle control structure

Abstract

This utility model discloses a limiting-fit angle control structure, including an angle control protrusion and an angle control recess. The angle control protrusion and the angle control recess are rotatably connected by a rotating shaft. The inner side of the angle control protrusion is provided with a first mounting surface, and the outer periphery of the first mounting surface is provided with a boss. The inner side of the angle control recess is provided with a second mounting surface, and the second mounting surface has an arc-shaped groove that rotatably engages with the boss. This limiting-fit angle control structure, through the use of a rotating shaft, enables the angle control protrusion and the angle control recess to be rotatably connected. Simultaneously, the boss on the outer periphery of the first mounting surface of the angle control protrusion rotatably engages with the arc-shaped groove on the second mounting surface of the angle control recess, thus limiting the relative rotation angle between the two. This prevents excessive rotation during monitor bracket rotation adjustment, achieving limiting-fit angle control and ensuring the stability and controllability of the structure during rotation.

Description

Technical Field

[0001] This utility model relates to the field of monitor bracket technology, specifically to a limiting and coordinating angle control structure. Background Technology

[0002] In the monitor stand industry, traditional angle control structures often suffer from insufficient angle adjustment precision and poor limiting effect. During long-term use, due to the unstable fit between rotating parts, loosening and wobbling can easily occur, leading to inaccurate monitor angle positioning and affecting the user experience. At the same time, traditional rotating shaft connection methods are mostly simple circular shaft fits, which are prone to relative rotation after assembly, making it difficult to ensure the stability of the monitor stand when adjusting the angle.

[0003] Based on the above, this utility model proposes a limiting and coordinating angle control structure, which can effectively solve the above problems. Utility Model Content

It is understandable that some well-known structures and their descriptions may be omitted in the drawings for those skilled in the art. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0018] A limiting and engaging angle control structure includes an angle control protrusion 1 and an angle control recess 2; the angle control protrusion 1 and the angle control recess 2 are rotatably connected by a rotating shaft 3; the inner side of the angle control protrusion 1 is provided with a first mounting surface 101, and the outer periphery of the first mounting surface 101 is provided with a boss 102; the inner side of the angle control recess 2 is provided with a second mounting surface 201, and the second mounting surface 201 has an arcuate groove 202 that rotatably engages with the boss 102.

The rotating shaft 3 and the angle control protrusion 1 are firmly fixed by the threaded connection to prevent them from separating during relative rotation. This enhances the connection strength and stability of the overall structure and ensures that the angle control protrusion 1 can rotate stably around the rotating shaft 3.

[0025] Furthermore, in another embodiment, the rotating shaft 3 is sequentially fitted with a first washer 5, a first positioning ring 6, a second positioning ring 7, a second washer 8, a first spring washer 9, and a second spring washer 10 from the external thread portion 301 to the limiting protrusion 302; the first washer 5 and the first positioning ring 6 are installed between the first mounting surface 101 and the second mounting surface 201; the second positioning ring 7, the second washer 8, the first spring washer 9, and the second spring washer 10 are installed between the first mounting surface 101 and the nut 4.

[0026] Furthermore, in another embodiment, the second mounting surface 201 has a mounting groove 205 for the first washer 5 to be inserted.

[0027] Furthermore, in another embodiment, both the outer sides of the first positioning ring 6 and the second positioning ring 7 are provided with L-shaped buckles 601.

[0030] By setting up the inspection cover 11, the internal components of the angle control protrusion 1, such as nuts, can be protected, preventing dust, impurities, etc. from entering and affecting the normal operation of the components. At the same time, it facilitates the subsequent inspection and maintenance of the internal components.

[0031] Furthermore, in another embodiment, the angle control protrusion 1 is provided with a connecting block 104 that engages with the connecting groove 111.

[0032] By engaging the connecting block 104 inside the angle control protrusion 1 with the connecting groove 111 of the inspection cover 11, a quick and stable connection between the inspection cover 11 and the angle control protrusion 1 is achieved.
