Description

Technical Field

[0001] This utility model relates to the field of projectors, and specifically to a projector bracket connecting and rotating device. Background Technology

[0002] With the rapid development of projection technology, projectors are increasingly widely used, not only in traditional scenarios such as business meetings and education and training, but also gradually entering fields such as home entertainment and personal office work. To facilitate users in adjusting the projection angle according to their actual needs, adjustable stands are now commonly available on the market, allowing for vertical and horizontal angle adjustments. However, existing projector stands generally suffer from complex designs, limited adjustment ranges, and cumbersome installation, making it difficult to meet users' needs for multi-angle, stepless adjustment. Furthermore, they are prone to loosening after prolonged use, affecting projection quality and user experience.

[0003] Traditional projector stands achieve projection angle adjustment through complex multi-axis designs or angle limiting devices. While these structures can meet angle adjustment needs to a certain extent, they also bring problems such as large size, difficult installation, and high maintenance costs. Furthermore, some existing structures have limitations in adjustment steps, typically 5-8 degrees at a time, making it difficult for users to achieve precise control when more fine adjustments are needed. In addition, traditional designs lack effective wear-resistant features, making them prone to wear and tear over long-term use, leading to loosening and affecting the stability of the stand. Summary of the Invention

[0004] To address the aforementioned issues, this utility model provides a projector bracket connecting rotation device. This device features a simple design, enabling arbitrary angle adjustment in the vertical direction. The use of wear-resistant friction plates and anti-rotation nuts enhances the device's lifespan and stability. Furthermore, the device's structure is relatively simple, making installation and operation more convenient. It effectively overcomes the shortcomings of existing technologies and meets users' needs for stepless angle adjustment and robust durability of projectors.

[0005] This utility model is achieved through the following technical solution: a projector bracket connecting rotation device, comprising:

[0006] The projector housing and the base bracket are rotatably mounted on the projector housing and are used to support the bottom of the projector housing. The projector housing can be adjusted to any projection angle relative to the base bracket.

[0007] A pivot is provided between the base bracket and the projector housing. The pivot passes through the projector housing and the base bracket and is locked to them by an anti-rotation nut.

[0008] One or more wear-resistant pads are provided between the base bracket and the rotating mating surface of the projector housing. After being locked with the rotating shaft by the anti-rotation nut, one or more wear-resistant pads are pressed together.

[0009] As a preferred technical solution, the rotating shaft is a rotating shaft screw with an external thread at its upper end, and the locking nut and the rotating shaft screw are locked together by thread engagement.

[0010] As a preferred technical solution, the inner side of the projector housing is provided with a nut anti-rotation position corresponding to the position of the anti-rotation nut, and the anti-rotation nut is installed in the nut anti-rotation position.

[0011] As a preferred technical solution, the wear-resistant pad includes a first wear-resistant pad and a second wear-resistant pad, which are stacked between the base bracket and the projector housing.

[0012] As a preferred technical solution, each of the base brackets is provided with a rotating shaft mounting port, and the rotating shaft component is disposed in the rotating shaft mounting port.

[0013] As a preferred technical solution, a decorative piece is installed inside the shaft mounting port.

[0014] As a preferred technical solution, a friction plate mounting groove is further provided between the base bracket and the rotating mating surface of the projector housing, and the friction-resistant plate is set in the corresponding friction-resistant plate mounting groove.

[0015] As a preferred technical solution, the mounting surface between the rotating shaft and the projector housing is further provided with a third friction-resistant sheet.

[0016] The beneficial effects of this utility model are: this utility model realizes arbitrary angle adjustment of the projector in the vertical direction through the rotating shaft method, without the need for complex multi-rotating shafts or angle limiting devices, avoiding the 5-8 degree step limitation existing in the prior art, and achieving the effect of stepless adjustment;

[0017] By incorporating wear-resistant friction pads between the projector housing and the base bracket, the durability and stability of the device are significantly improved, wear is reduced, and service life is extended.

[0018] Meanwhile, the anti-rotation nut design effectively prevents the shaft from loosening during long-term use, ensuring the stability and reliability of the device at different angles;

[0026] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0027] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0028] like Figures 1-3 As shown, this utility model provides a projector bracket connecting rotation device, including a projector housing 7 and a base bracket 4. The base bracket 4 is rotatably mounted on the projector housing 7 to support the bottom of the projector housing 7, allowing the projector housing 7 to be adjusted to any projection angle relative to the base bracket 4, thereby achieving flexible adjustment in the vertical direction. With this structure, the projector can meet the personalized projection angle needs of users in different scenarios, eliminating the need for adjustment via multiple rotating shafts, making the structure simpler, and avoiding the 5-8 degree angle limitation problem of traditional devices, achieving a stepless adjustment effect.

[0029] A pivot 5 is provided between the base bracket 4 and the projector housing 7. The pivot 5 passes through the projector housing 7 and the base bracket 4, and is locked to the projector housing 7 and the base bracket 4 by an anti-rotation nut 1. The pivot 5 is preferably designed as a pivot screw with an external thread at its upper end, which is connected to the anti-rotation nut 1 through thread engagement and locking.

[0030] The structure of the anti-rotation nut 1 can effectively prevent the rotating shaft 5 from loosening during long-term use, thereby ensuring that the device remains stable after any angle adjustment and preventing instability during use.

[0031] The inner side of the projector housing 7 is provided with a nut anti-rotation position 8 at the position corresponding to the anti-rotation nut 1. By installing the anti-rotation nut 1 in the nut anti-rotation position 8, the anti-rotation function of the nut is further enhanced, making the structure more stable.

[0032] To enhance the durability of the structure and reduce wear caused by friction, at least one wear-resistant sheet is provided between the rotating mating surface of the base bracket 4 and the projector housing 7.

[0033] When the anti-rotation nut 1 is locked by the rotating shaft 5, the friction-resistant plate is pressed between the rotating mating surfaces, which increases the friction of the mating surfaces. This reduces wear caused by friction while achieving a stable lock, and significantly improves the service life of the device.

[0034] Preferably, the wear-resistant sheet may include a first wear-resistant sheet 3 and a second wear-resistant sheet 2, which are stacked between the base bracket 4 and the projector housing 7 to further enhance the wear resistance and ensure the stability of the device after long-term use.

[0035] A pivot mounting port is also provided on the base bracket 4, and the pivot component 5 is disposed in the pivot mounting port so that the pivot component 5 can be stably positioned between the base bracket 4 and the projector housing 7.

[0036] To enhance the overall aesthetics, a decorative piece 6 can be installed inside the hinge mounting opening, providing both aesthetic appeal and protection. To facilitate easier and more stable installation of the friction-resistant sheet, a friction-resistant sheet mounting groove is provided between the rotating mating surfaces of the base bracket 4 and the projector housing 7. The friction-resistant sheet is positioned within the corresponding groove to prevent displacement during use and further ensure the stability and durability of the device. A third friction-resistant sheet 9 is also provided on the mating surface between the hinge and the projector housing.

[0037] Through the above structural design, the projector bracket connecting rotation device provided by this utility model has a simple structure, making it easy to install and adjust. The projector housing 7 can be adjusted at any angle in the vertical direction, avoiding the installation difficulty of existing complex multi-axis structures and improving the user experience. The combination of the wear-resistant friction plate and the anti-rotation nut 1 not only improves the durability and reliability of the device, but also prevents instability caused by loosening during projector use, providing users with a more convenient and efficient projection support device.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
