Description

Technical Field

[0001] The utility model relates to the technical field of adjustable projection devices, and more specifically, it relates to an adjustable projection device. Background Art

[0002] In the existing technology of adjustable projection devices, the flexibility of angle adjustment and the stability of fixation are key factors to ensure their effective use. However, there are certain defects in the existing adjustable projection devices when adjusting the angle, especially in controlling the friction force.

[0003] First of all, the existing adjustable projection devices often fail to fully consider the friction force problem when adjusting the angle in their design. During actual use, since it is necessary to adjust the angle of the projection device to meet different viewing requirements, the existing devices may lack an effective friction force control mechanism. This results in that when adjusting the angle, the projection device may be difficult to adjust smoothly due to excessive friction force, or may not be able to maintain a stable fixed state due to too small friction force. In this case, users may need to spend a lot of effort to adjust the angle, or the projection device may shake or tilt during the adjustment process, thus affecting the stability of the projection and the viewing effect.

[0004] Secondly, the existing adjustable projection devices have deficiencies in the fixed stability. Since the projection device needs to be fixed at different angles, the fixed stability is the key to ensuring the projection effect. However, the existing devices may lack an effective fixing mechanism or the fixing process is cumbersome, making it difficult for the device to maintain a stable fixed state after adjusting the angle. In this case, the projection device may easily shake or tilt, thus affecting the stability of the projection and the viewing effect. Summary of the Utility Model

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the present utility model provides an adjustable projection device, having the following

[0018] beneficial effects:

[0019] 1. The design of the adjustment mechanism enables the projection device to flexibly adjust the friction between the side plate and the fixed sleeve, ensuring the stability of the projector in different usage environments. By pushing the fixed sleeve and compressing the compression spring, the friction is increased. With the cooperation of the one-way block and the one-way sleeve, self-locking fixation between the fixed sleeve and the insertion rod is achieved. This design not only enables the device to be quickly fixed, but also, when adjustment is needed, can be easily unlocked through the cooperation of the follower plate and the telescopic disc, providing great convenience to users.

[0020] 2. The clamping mechanism, through the configuration of the shrinkage sleeve and the slider, achieves precise clamping of the one-way block on the one-way sleeve, ensuring the stability of the position between the insertion rod and the fixed sleeve. Due to the action of the spring, the slider can maintain resilience, thus keeping the structure compact and the operation simple during the adjustment process. This design effectively reduces the relative sliding between components, improving the service life and reliability of the entire device.

[0021] 3. The rotation mechanism uses the combination of the slide rail and the sliding block to enable the adjustment plate to rotate smoothly along the side plate.

[0028] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will describe the present utility model in detail with reference to the drawings and in conjunction with the embodiments.

[0029] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs.

[0030] In the present utility model, unless otherwise stated, the orientations such as "upper and lower" are usually in the direction shown in the drawings, or in the vertical, perpendicular or gravitational direction; similarly, for the convenience of understanding and description, "left and right" are usually in the left and right shown in the drawings; "inside and outside" refer to the inside and outside relative to the contour of each component itself, but the above orientation terms are not used to limit the present utility model.

[0031] Please refer to Figures 1-5 , an adjustable projection device, comprising a side plate 1, the side plate 1 is installed on an external device, an adjusting mechanism is arranged on the side plate 1, the adjusting mechanism includes a rotating mechanism, an adjusting plate 2, an insertion rod 3, a fixing sleeve 4, a clamping mechanism, a follower plate 5, a follower frame 6 and a telescopic disc 7, the rotating mechanism is cooperatively connected to the side plate 1 and the adjusting plate 2, the insertion rod 3 is installed on the side plate 1, an arc-shaped groove 8 is formed on the side plate 1, the insertion rod 3 is slidably connected in the arc-shaped groove 8, the fixing sleeve 4 and the insertion rod 3 are coaxially arranged, the clamping mechanism is cooperatively connected to the insertion rod 3 and the fixing sleeve 4, the follower frame 6 is slidably connected to the fixing sleeve 4, a lateral groove 9 is formed on the side wall of the fixing sleeve 4, the follower plate 5 is slidably connected in the lateral groove 9, the follower plate 5 is slidably connected in the follower frame 6, the telescopic disc 7 is installed on the follower frame 6, a push disc 10 is arranged on the fixing sleeve 4, a compression spring 11 is arranged on the push disc 10, the compression spring 11 abuts against the side plate 1, the clamping mechanism includes a shrinkage sleeve 12 and a slider 13, the shrinkage sleeve 12 is installed on the fixing sleeve 4, the slider 13 is slidably connected to the shrinkage sleeve 12, the follower plate 5 is installed on the slider 13, a one-way block 14 is arranged on each slider 13, a plurality of one-way sleeves 15 are arranged on the side wall of the insertion rod 3, the one-way block 14 is stuck in the one-way sleeve 15, a spring 16 is arranged on each slider 13, the spring 16 abuts against the fixing sleeve 4, and a telescopic sleeve 17 is coaxially arranged on the fixing sleeve 4.

[0032] In this embodiment, when it is necessary to adjust the friction between the fixed sleeve 4 and the side plate 1, first drive the fixed sleeve 4 to push towards the side plate 1, then the compression spring 11 will be compressed, thereby increasing the friction. As the positions of the fixed sleeve 4 and the insertion rod 3 change, the one-way block 14 and the one-way sleeve 15 also change positions. At this time, the slider 13 will be driven to expand along the shrinkage sleeve 12, and then the one-way block 14 will be abutted against the next one-way sleeve 15, thus completing one fixation. Then, under the pressure of the compression spring 11, the slider 13 shrinks towards the direction of the compression spring 11. At this time, the one-way block 14 abuts against the insertion rod 3, so self-locking is formed, thus completing the fixation process. When it is necessary to unlock, just press on the telescopic sleeve 17 and then unlock the engagement between the one-way block 14 and the one-way sleeve 15, and then pull the telescopic disc 7 backward. The slider 13 can be driven by the follower plate 5 to press on the shrinkage sleeve 12 to expand, thereby unlocking the fixation between the insertion rod 3 and the fixed sleeve 4.

[0033] Please refer to Figure 1 and Figure 2 , as an embodiment of the rotating mechanism: The rotating mechanism includes a slide rail 18 and a sliding block 19. The slide rail 18 is installed on the side plate 1, the sliding block 19 is installed on the adjusting plate 2, the sliding block 19 is slidably connected to the slide rail 18, a projector 20 is provided on the adjusting plate 2, the projector 20 is electrically connected to an external device, and a handle 21 is provided on the adjusting plate 2.

[0034] More specifically, when the elastic force adjustment is completed, the handle 21 can be used to drive the rotation of the adjusting plate 2. Since the sliding block 19 is installed on the adjusting plate 2 and the sliding block 19 is slidably connected to the slide rail 18, the angle of the projector 20 can be adjusted. Since the fixing force is adjusted, it can be fixed at the corresponding angle, thus completing the adjustment process.

[0035] In summary, when the overall device is in use or running: when it is necessary to adjust the friction between the fixing sleeve 4 and the side plate 1, the fixing sleeve 4 is first driven to push toward the side plate 1, and then the compression spring 11 is compressed, thereby increasing the friction. As the positions of the fixing sleeve 4 and the insertion rod 3 change, the one-way block 14 and the one-way sleeve 15 also change positions, and at this time, the slider 13 is driven to expand along the shrink sleeve 12, and then the one-way block 14 is abutted against the next one-way sleeve 15, thereby completing a fixation. Then, under the pressure of the compression spring 11, the slider 13 is contracted in the direction of the compression spring 11, and at this time the one-way block 14 is abutted against the insertion rod 3, thus forming a self-locking. The fixing process is thus completed. When it is necessary to release it, one only needs to press on the telescopic sleeve 17 and then release the clamping of the one-way block 14 and the one-way sleeve 15, and then pull the telescopic disk 7 backwards. The follower plate 5 can drive the slider 13 to press the shrinkage sleeve 12 to expand, thereby releasing the fixation between the insertion rod 3 and the fixed sleeve 4. When the elastic force adjustment is completed, the handle 21 can drive the adjustment plate 2 to rotate. Since the sliding block 19 is installed on the adjustment plate 2, the sliding block 19 is slidably connected to the slide rail 18, so the angle of the projector 20 can be adjusted. Since the fixing force is adjusted, it can be fixed at the corresponding angle, thereby completing the adjustment process.

[0036] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
