Description

Technical Field

[0001] This utility model relates to the field of projector technology, and in particular to an adjustable fixing mechanism for projectors. Background Technology

[0002] An adjustable mounting mechanism for a projector is a device used to install and fix a projector, and can adjust its position, angle and other parameters. Its core function is to achieve stable placement of the projector through structural design, and flexibly adjust the projection direction and height to adapt to different projection scenarios (such as walls and screens) and improve the projection effect (such as a square and clear image).

[0003] When using a projector, first fix the projector in a suitable position, plug in the power and turn it on. Then, adjust the relative rotation angle of the projector body to center the image. Next, rotate the lens focus ring to make the image clear. Finally, use the keystone correction function (manual or automatic) to correct image distortion and ensure a square and complete projection effect.

[0004] The existing technology has the following drawbacks: During the use of a projector, the flexibility of the angle adjustment of the fixing mechanism directly affects the projection effect. Most projector fixing mechanisms on the market either have a narrow angle adjustment range, making it difficult to meet the projection angle requirements in different scenarios, or the adjustment operation is complicated, often requiring additional tools to complete the angle positioning, which greatly reduces the user's convenience. Therefore, an adjustable fixing mechanism for projectors is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an adjustable fixing mechanism for projectors, aiming to improve the problem of inconvenient angle adjustment of projectors in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable fixing mechanism for a projector, comprising a main body, a bracket inserted into the outer wall of the main body, a wave groove fixedly connected to the inner wall of the bracket, an arc groove formed on the inner wall of the bracket, a side panel in contact with the inner wall of the bracket, a protrusion fixedly connected to the outer wall of the side panel, anti-slip silicone fixedly connected to the inner wall of the main body, and a buckle slidably connected to the inner wall of the main body.

[0007] As a further description of the above technical solution:

[0008] The outer wall of the anti-slip silicone is in contact with the inner wall of the bracket.

[0009] As a further description of the above technical solution:

[0010] The right end of the buckle contacts the outer wall of the wave groove, and the protrusion is inserted into the inner wall of the arc groove.

[0011] As a further description of the above technical solution:

[0012] The left sidewall of the buckle is elastically connected to the main body via a movable spring.

[0013] As a further description of the above technical solution:

[0014] The main body is rotatably connected to the support, allowing them to move relative to each other.

[0016] The side panel is connected to the outer inner wall of the main body.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this utility model, the main body angle can be quickly adjusted and positioned by the cooperation of the buckle and the wave groove. The adjustment process does not require additional tools and is simple and convenient to operate. At the same time, the large rotation angle allows the device to have more projection angle options, further improving the practicality of the device. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figures 1-3 This utility model provides an embodiment of an adjustable fixing mechanism for a projector, comprising a main body 1. The main body 1 has a maximum upward rotation angle of 90 degrees and a maximum downward rotation angle of 30 degrees. A bracket 2 is inserted into the outer wall of the main body 1. A trapezoidal foot pad is provided at the bottom of the bracket 2, which serves as an adjustable support. A wave groove 6 is fixedly connected to the inner wall of the bracket 2. The wave groove 6 is wave-shaped. When the buckle 5 moves from one set of recesses in the wave groove 6 to another set of recesses, the rotation angle of the main body 1 is 3 degrees. An arc-shaped groove 7 is formed on the inner wall of the bracket 2. The inner wall of the bracket 2 contacts a side panel 3. A protrusion 8 is fixedly connected to the outer wall of the side panel 3. The protrusion 8 serves a limiting function. When the protrusion 8 contacts the edge of the arc groove 7, it restricts the rotation angle of the main body 1. The inner wall of the main body 1 is fixedly connected with anti-slip silicone 9, and the inner wall of the main body 1 is slidably connected with a buckle 5. The main body 1 has a corresponding slot for the buckle 5, so that the buckle 5 can move left and right. The left side wall of the buckle 5 is elastically connected to the main body 1 through a movable spring 4. When the bracket 2 and the main body 1 rotate relative to each other, the buckle 5 is squeezed to move to the left or right, and the movable spring 4 is compressed. When resetting, the elastic force of the movable spring 4 is used to reset the buckle 5. This can be repeated so that the main body 1 and the bracket 2 can rotate relative to each other, which is convenient for adjusting the angle of the projector lens.

[0029] Reference Figures 4-6 The outer wall of the anti-slip silicone 9 contacts the inner wall of the bracket 2. The anti-slip silicone 9 can fix the machine at the required angle and prevent excessive or arbitrary rotation. The right end of the buckle 5 contacts the outer wall of the wave groove 6. The protrusion 8 is inserted into the inner wall of the arc groove 7 to prevent the equipment from rotating too much. The main body 1 is relatively rotated to connect the bracket 2, so that it moves relative to the main body 1. The side panel 3 is connected to the outer inner wall of the main body 1. After the main body 1 and the side panel 3 are threadedly connected, the side panel 3 can be limited.

[0030] Working principle: When the angle of the main body 1 needs to be adjusted, the main body 1 is manually rotated. The main body 1 will rotate along with the buckle 5. When the buckle 5 contacts the protruding point of the wave groove 6, the protruding point will squeeze the buckle 5, causing the buckle 5 to move to the left or right and squeeze the movable spring 4. When the buckle 5 is located at the concave point of the wave groove 6, under the elastic force of the movable spring 4, the buckle 5 moves to the left or right until it contacts the concave point. During the manual adjustment process, the device will have a clear damping feel and tactile feedback. When no rotation adjustment is needed, the protrusion 8 is inserted into the inner wall of the arc groove 7 to limit the movement and prevent the device from rotating too much.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
