Description

Technical Field

[0001] The utility model relates to the field of projectors, and particularly to a hanging installation structure for a projector. Background Art

[0002] As a common display device, projectors are widely used in occasions such as offices, education, and home entertainment. During actual use, the installation method of the projector has a crucial impact on its projection effect. In the existing technology, the hanging installation method of projectors usually adopts a fixed bracket or wall-mounted installation. Although the traditional installation method can fix the projector, there are still some relatively prominent defects.

[0003] First of all, most of the traditional projector hanging methods adopt a single fixed bracket, and the projector is directly installed on the wall or ceiling through screws or hooks. A major defect of this method is that the installation is not stable. Especially for larger-sized or heavier projectors, it is easy to shake when hanging, resulting in a jittery projection image and affecting the viewing effect. Due to the lack of an adequate support adjustment mechanism in the fixing method, the stability of the projector is difficult to guarantee. Especially when subjected to slight external vibrations, the position of the projector is prone to shift, resulting in frequent adjustments.

[0004] Secondly, the existing fixed installation methods generally cannot effectively adjust the projection angle of the projector. Due to the limitation of the design of the traditional fixed bracket, the angle between the projection lens of the projection host and the horizontal plane is fixed and cannot be flexibly adjusted according to different usage environments. For example, in cases where the projection angle needs to be adjusted to adapt to different projection screens or viewer perspectives, the traditional installation method often requires additional adjustment tools or even reinstallation of the projector, which is time-consuming, laborious, and inconvenient to operate.

[0005] In addition, the existing projector hanging structures lack flexibility, are difficult to adapt to the unevenness of the wall or the requirements of different positions, and cannot achieve fine angle adjustment, resulting in poor installation effects in some special scenarios (such as uneven walls or installation surfaces). Therefore, there is a large room for improvement in the flexibility, stability, and angle adjustment of the existing projector installation methods. Summary of the Utility Model

[0006] In order to solve the above problems, the utility model provides a hanging installation structure for a projector, which can not only maintain stability while fixing the projector, but also flexibly adjust the projection angle according to actual needs, thereby improving the usability and projection effect of the projector.

[0007] The utility model is realized through the following technical solutions: A hanging installation structure for a projector, comprising:

[0008] A projection host, the front of the projection host is a projection surface, a projection lens is arranged on the projection surface, and the back of the projection host forms a hanging surface;

[0009] A plurality of hanging holes are arranged on the hanging surface, and the projection host is hung on the fixing screws on the wall through one or more hanging holes. The fixing screws hook the projection host and are used to limit the freedom degree of the projection host relative to the wall in the vertical plane;

[0010] A plurality of support nuts, which are all movably installed on the hanging surface of the projection host, and each support nut can adjust the telescopic length on the vertical plane of the wall, so as to adjust the hanging angle of the projection host relative to the wall.

[0011] As a preferred technical solution, the support nut includes an adjusting cap and an adjusting screw rod. The adjusting screw rod is threadedly connected to the threaded hole on the back of the projection host, and the projection host is moved in the vertical direction away from the wall by rotating the adjusting cap.

[0012] As a preferred technical solution, the hanging hole includes a first notch and a second notch. The first notch communicates with the second notch and combines to form a keyhole-shaped hanging hole. The fixing screw on the wall is buckled into the second notch through the first notch.

[0013] As a preferred technical solution, the outer circumferential surface of the adjusting cap is provided with adjusting threads.

[0014] As a preferred technical solution, an inclined angle is formed between the projection lens of the projection host and the horizontal plane.

[0015] The beneficial effects of the present utility model are as follows: By arranging a plurality of hanging holes and support nuts, the projector can be stably hung on the wall, and through the telescopic adjustment function of the support nuts, the problems that the projector is prone to shaking and unstable installation in the traditional installation method are effectively solved;

[0023] All the features disclosed in this specification, or all the steps in the disclosed methods or processes, except for mutually exclusive features and / or steps, can be combined in any way.

[0024] Any feature disclosed in this specification (including any additional claims, abstract, and drawings), unless specifically stated, can be replaced by other equivalent or similar-purpose alternative features. That is, unless specifically stated, each feature is only an example of a series of equivalent or similar features.

[0025] As Figure 1 and Figure 2 shown, a hanging and mounting structure of a projector of the present invention includes a projection host 1. The front of the projection host 1 is a projection surface, and a projection lens 6 is arranged on the projection surface. The back of the projection host 1 forms a hanging surface 3;

[0026] Among them, a plurality of hanging holes 4 are arranged on the hanging surface 3. The projection host 1 is hung on the fixing screws on the wall through the plurality of hanging holes 4. The fixing screws hook the projection host 1 and are used to limit the degree of freedom of the projection host 1 relative to the wall in the vertical plane;

[0027] It also includes a plurality of supporting nuts 2, which are all movably installed on the hanging surface 3 of the projection host 1. Each supporting nut 2 can adjust the telescopic length on the vertical plane of the wall, so as to adjust the hanging angle of the projection host 1 relative to the horizontal plane. In this embodiment, the plurality of supporting nuts 2 are arranged on the hanging surface 3 of the projection host 1 at the positions of four corners for four-point support. When the protruding lengths of all the supporting nuts 2 are the same, the surface of the supporting nut 2 in contact with the wall is in the same horizontal plane. At this time, the whole projection host 1 fits the wall and is parallel to the wall. If you want to adjust the angle on any side, just rotate the supporting nut 2 at any position, and the projection host 1 can be adjusted to any projection direction.

[0028] Among them, as Figure 2 shown, the supporting nut 2 includes an adjusting cap 21 and an adjusting screw rod 22. The adjusting screw rod 22 is threadedly connected to the threaded hole 5 on the back of the projection host 1. By rotating the adjusting cap 21, the projection host 1 is moved in the vertical direction away from the wall. When the projection host 1 needs to be adjusted, just rotate the adjusting cap 21, and then the adjusting screw rod 22 rotates threadedly. When the adjusting screw rod 22 protrudes, since the T-shaped part of the fixing screw is buckled into the hanging hole 4, at this time, the projection host 1 can be tightened by using the fixing screw, and the supporting nut 2 is used as a reverse thrust.

[0029] Please continue to refer to Figure 2 , the hanging hole 4 includes a first notch 41 and a second notch 42. The first notch 41 communicates with the second notch 42 and combines to form a keyhole-shaped hanging hole 4. The fixing screw on the wall is buckled into the second notch 42 through the first notch 41. During installation, the T-shaped part of the fixing screw is buckled into the second notch 42 through the first notch 41, so it cannot be separated from the projection host 1 in the vertical direction.

[0030] In order to facilitate the rotation of the adjusting cap 21, in this embodiment, the outer circumferential surface of the adjusting cap 21 is provided with adjusting threads.

[0031] As Figure 3 shown, an inclined angle is formed between the projection lens 6 of the projection host 1 and the horizontal plane.

[0032] By setting a plurality of hanging holes 4 and supporting nuts 2, the present invention enables the projector to be stably hung on the wall, and through the telescopic adjustment function of the supporting nuts 2, effectively solves the problems that the projector is prone to shaking and the installation is not stable in the traditional installation method;

[0033] Meanwhile, through the supporting nut 2, the angle between the projection host 1 and the wall surface can be freely adjusted according to actual needs, thereby adjusting the position of the projection screen, enabling the projector to adapt to different usage environments and projection requirements, simplifying the installation and angle adjustment operations of the projector, avoiding the cumbersome steps of frequently reinstalling or using additional tools to adjust the projection angle in the traditional way, improving the installation efficiency and usage convenience of the projector, and by utilizing the reverse action of the key-shaped hanging hole 4 and the supporting nut 2, when the supporting nut 2 extends away from the projection host 1, a reaction force can be generated, enabling the fixing screw to tighten the projection host 1 and making the installation of the projection host 1 more stable.

[0034] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement that can be thought of without creative work should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
