The projector usually needs to be set on a rotation adjustment structure, and by adjusting the rotation adjustment structure, the user is allowed to adjust the projection angle and position of the projector.

[0003] However, sometimes these rotation adjustment structures may have insufficient stability during rotation due to insufficient design or low manufacturing precision.

[0004] Therefore, based on the above problems, the prior art needs to be improved. Utility Model Content

[0007] By adopting the above technical solution, the rotation adjustment structure as a whole can be stably set at a preset position through the base, and the limit block in the installation channel is installed and engaged into the limit groove set on the rotating shaft, so that the rotating shaft and the fixed shaft are stably installed and connected; through the design of the limit groove and the limit block, the stability of the rotation adjustment structure during the rotation process can be ensured. The cooperation of the limit groove and the limit block can effectively prevent the structure from exceeding the predetermined rotation range, thereby enhancing the overall stability.

[0008] Optionally, a plurality of the limit blocks are provided, and the plurality of limit blocks are evenly spaced apart.

[0009] By adopting the above technical solution, multiple limit blocks are evenly spaced to provide more support points, effectively enhancing the stability of the rotating structure. The shaking and instability of the structure during rotation can be reduced, making the adjustment more stable and reliable. The setting of multiple limit blocks can share the pressure and load of the rotating structure, reducing the risk of single-point failure, thereby enhancing the reliability and durability of the structure. Setting multiple limit blocks and setting them evenly spaced further enhances the stability, accuracy, applicability, operability and reliability of the rotating adjustment structure, and improves its performance and user experience in practical applications.

[0010] Optionally, a second mounting member is further provided at one end of the fixed shaft away from the first mounting member, and the first mounting member and the second mounting member have the same structure.

[0011] By adopting the above technical solution, the addition of the second mounting member can balance the weight distribution of the rotation adjustment structure, thereby enhancing the overall stability. By arranging mounting members at both ends of the fixed shaft, the swing and shaking of the structure during the rotation process can be reduced, thereby improving the stability and reliability of the rotation adjustment.

This design can effectively reduce the vibration and inertia of the shaft during rotation, making the movement of the rotation adjustment structure smoother and slower, and improving the stability and precision of the equipment. The enhanced damping effect can reduce the wear and loss of the structure. By reducing the impact and inertial force during rotation, the degree of wear of the structure can be reduced, the service life of the rotation adjustment structure can be extended, and the frequency and cost of maintenance and replacement can be reduced. The enhanced damping effect can enhance the stability of the rotation adjustment structure. Stable rotational motion can ensure that the equipment maintains a stable working state during use, and improves the reliability and safety of the structure.

[0014] Optionally, a positioning pin is provided on the mounting block.

[0015] By adopting the above technical solution, the positioning pin can provide accurate positioning between the mounting block and the device to be mounted, ensuring the accurate position of the device to be mounted on the mounting block, preventing the device to be mounted from deflecting or swinging during the rotation process, thereby ensuring the stability and accuracy of the rotation adjustment of the device to be mounted.

[0016] Optionally, a slot is recessed into the mounting block.

[0017] By adopting the above technical solution, the user can penetrate the device to be installed and the slot through fasteners such as bolts, so that the device to be installed can be stably installed on the mounting block, thereby improving the stability and accuracy of the rotation adjustment of the device to be installed.

[0018] Optionally, a mounting groove is recessed on a side of the base away from the fixed axis.

[0019] By adopting the above technical solution, the mounting groove can provide a stable mounting position for fixing the base or other equipment. It can ensure that the equipment is firmly installed, reduce the shaking and displacement that may occur during use, and improve the stability of the equipment. The setting of the mounting groove increases the stability of the equipment. The concave design of the base can increase the contact area between the mounting groove and the base, improve the firmness of the installation, and thus enhance the stability and safety of the equipment during use.

[0020] Optionally, a mounting column is provided in the mounting groove.

[0021] By adopting the above technical solution, the mounting column can provide accurate positioning between the base and the position to be installed, ensuring the accurate position of the base at the position to be installed, preventing the base from deflecting or swinging, and thus ensuring the overall stability and adjustment accuracy of the rotation adjustment structure.

[0022] In summary, this application has at least the following beneficial effects:

[0023] 1. The base enables the rotation adjustment structure to be stably set at a preset position. The limit block in the installation channel is installed and engaged with the limit groove set on the rotating shaft, so that the rotating shaft and the fixed shaft are stably installed and connected. The design of the limit groove and the limit block can ensure the stability of the rotation adjustment structure during the rotation process. The cooperation of the limit groove and the limit block can effectively prevent the structure from exceeding the preset rotation range, thereby enhancing the overall stability.

[0024] 2. Multiple limit blocks are evenly spaced to provide more support points, effectively enhancing the stability of the rotating structure. It can reduce the shaking and instability of the structure during rotation, making the adjustment more stable and reliable. The setting of multiple limit blocks can share the pressure and load of the rotating structure, reduce the risk of single point failure, and thus enhance the reliability and durability of the structure. Setting multiple limit blocks at even intervals further enhances the stability, accuracy, applicability, operability and reliability of the rotating adjustment structure, and improves its performance and user experience in practical applications.
