Description
Technical Field
[0001] This utility model relates to the field of adjustment devices, and in particular to a projector mounting and adjustment device. Background Technology
[0002] A projector is a device that can magnify and project images or videos onto a screen or wall. Projector mounting and adjustment devices are accessories used to fix and adjust the position of the projector. Their main function is to ensure that the projector can be installed correctly, that the image is accurately projected onto the ideal position of the screen or wall, avoid distortion or offset, and achieve the best projection effect.
[0003] However, most of the existing projector installation and adjustment devices on the market have a relatively fixed adjustment direction, and can only project in a fixed single direction. When users need to rotate the projector, they need to reinstall it, which reduces the flexibility and applicability of the projector.
[0004] Therefore, those skilled in the art have provided a projector mounting and adjustment device to solve the problems mentioned in the background art. Utility Model Content
[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a projector installation and adjustment device. Through the cooperation of the multi-hole plate, the limiting post, the first spring, the first limiting plate, and the rotating handle in the first slot, it is convenient for users to adjust the pitch of the projector according to their needs. Through the cooperation of the cylinder in the first groove, the third spring, the limiting block, the slider, the second spring, the second limiting plate, and the limiting plate, it is convenient for users to rotate and move the projector according to their needs.
[0006] To achieve the above objectives, this utility model provides a projector installation and adjustment device, including a fixed plate, a rotating assembly, and a rotating component. A fixed column is fixedly connected to the center of the lower surface of the fixed plate, and mounting holes are respectively opened at the four corners of the lower surface of the fixed plate. A U-shaped plate is fixedly connected to the lower surface of the fixed column, and a rotating assembly is arranged inside the U-shaped plate. A connecting column is rotatably connected to the center of the inner walls on both sides of the U-shaped plate. A connecting shaft is fixedly connected to the center of the outer wall of the connecting column. The front end of the connecting column passes through the U-shaped plate to the outside of the U-shaped plate and is fixedly connected to a perforated plate. A placement plate is fixedly connected to the lower end of the outer wall of the front end of the U-shaped plate. A first slot is opened inside the placement plate, and a first spring is fixedly connected to the center of the inner wall of the front end of the first slot.
[0007] A connecting plate is fixedly connected to the lower surface of the connecting shaft. A rotating assembly is provided inside the connecting plate. The rotating assembly includes a cylinder. A first groove is formed in the middle of the lower surface of the connecting plate. Multiple second grooves are evenly formed in the middle of the outer wall of the cylinder. Multiple second slots are evenly formed in the middle of the inner wall of the first groove. A second spring is fixedly connected to the middle of the inner wall of the second slot on the side away from the center of the cylinder. A limiting plate is fixedly connected to the lower surface of the cylinder. The limiting plate slides in the first groove. The projector body is fixedly connected to the lower surface of the limiting plate.
[0008] The above technical solution allows users to easily install the mounting plate securely onto the ceiling or bracket using screws through the mounting holes.
[0009] Furthermore, a limiting plate is fixedly connected to the rear end of the first spring, a limiting post is fixedly connected to the middle of the first limiting plate, and the first limiting plate slides within the first slot.
[0010] The above technical solution allows the first limiting plate to slide within the first slot, ensuring that the limiting plate can only move along the direction of the slot, thus preventing offset or rotation in other directions.
[0011] Furthermore, the first spring is sleeved on the outside of the limiting post, and the outer wall of the rear end of the limiting post passes through the first slot and the placement plate in sequence and is connected to the multi-hole disc in a snap-fit connection.
[0012] The above technical solution provides axial guidance for the limiting post by means of spring sleeve, ensuring that its movement trajectory is stable and does not deviate. The limiting post is connected to the multi-hole disk by means of a snap-fit connection at the rear end, realizing fast and reliable locking of multiple horizontal angles of the projector.
[0013] Furthermore, the front end of the limiting post passes through the first slot hole to the outside of the placement plate and is fixedly connected to a rotating handle;
[0014] The above technical solution allows users to easily pull it out of the holes in the multi-hole disc using a rotating handle.
[0015] Furthermore, a plurality of limiting blocks are uniformly fixedly connected to the lower end of the outer wall of the cylinder, and the side of the limiting blocks away from the center of the cylinder is slidably connected to the inner wall of the first groove.
[0016] By using the above technical solution, the limiting block slides along the inner wall of the first groove, ensuring that the limiting block can only slide in a straight line or arc along the path specified by the inner wall of the first groove, thus preventing unnecessary offset or rotation when subjected to force.
[0017] Furthermore, a second limiting plate is fixedly connected to the side of the second spring near the center of the cylinder, and a slider is fixedly connected to the side of the second limiting plate near the center of the cylinder. The second limiting plate slides within the second slot.
[0018] With the above technical solution, the second limiting plate slides within the second slot, allowing the user to move to different positions as needed.
[0019] Furthermore, the slider on the side near the center of the cylinder passes through the second slot hole to the inside of the first groove and is engaged with the second groove.
[0020] The above technical solution allows the slider to pass through the No. 2 slot and enter the No. 1 groove on the side near the center of the cylinder, while simultaneously engaging with the No. 2 groove. This design plays a crucial role in linkage and locking.
[0021] Furthermore, a No. 3 spring is fixedly connected to the middle of the upper surface of the limiting plate, and the upper end of the No. 3 spring passes through the cylinder and is tightly fitted to the top surface inside the No. 1 groove.
[0022] The above technical solution involves the upper end of spring number three fitting tightly against the top surface inside groove number one. When the user adjusts the projector angle, spring number three is compressed. Once released, the spring's elasticity pushes the relevant components to move, automatically returning them to the preset initial position or locking them into the nearest positioning point, achieving automatic reset and precise positioning.
[0023] This utility model has the following beneficial effects:
[0024] 1. The projector installation and adjustment device proposed in this utility model, through the cooperation of the multi-hole plate, the limiting post and the first spring, the first limiting plate and the rotating handle in the first slot, facilitates the user to adjust the pitch of the projector while avoiding the angle displacement problem caused by the loose bolts of the traditional bracket, thereby improving the stability of the adjustment device.
[0025] 2. The projector installation and adjustment device proposed in this utility model, through the coordinated use of the inner cylinder of the first groove, the third spring, the limiting block, the slider, the second spring, the second limiting plate and the limiting disc, makes it convenient for users to rotate the projector at multiple angles according to their needs, while also solving the problems of cumbersome adjustment and easy loosening of traditional brackets, thereby improving the flexibility of angle adjustment.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0035] Reference Figure 1-3This utility model provides a specific embodiment: a projector installation and adjustment device, including a fixed plate 1, a rotating component 6 and a rotating component 8. A fixed column 2 is fixedly connected to the middle of the lower surface of the fixed plate 1. Mounting holes 5 are respectively opened at the four corners of the lower surface of the fixed plate 1. A U-shaped plate 3 is fixedly connected to the lower surface of the fixed column 2. The rotating component 6 is arranged inside the U-shaped plate 3. A connecting column 602 is rotatably connected to the middle of the inner walls on both sides of the U-shaped plate 3. A connecting shaft 601 is fixedly connected to the middle of the outer wall of the connecting column 602. The front end of the connecting column 602 passes through the U-shaped plate 3 to the outside of the U-shaped plate 3 and is fixedly connected to a perforated plate 603. A placement plate 604 is fixedly connected to the lower end of the outer wall of the front end of the U-shaped plate 3. A first slot 605 is opened inside the placement plate 604. A first spring 606 is fixedly connected to the middle of the inner wall of the front end of the first slot 605.
[0036] A connecting plate 7 is fixedly connected to the lower surface of the connecting shaft 601. A rotating assembly 8 is provided inside the connecting plate 7. The rotating assembly 8 includes a cylinder 802. A first groove 801 is opened in the middle of the lower surface of the connecting plate 7. Multiple second grooves 804 are evenly opened in the middle of the outer wall of the cylinder 802. Multiple second slots 807 are evenly opened in the middle of the inner wall of the first groove 801. A second spring 808 is fixedly connected to the middle of the inner wall of the second slot 807 on the side away from the center of the cylinder 802. A limiting plate 810 is fixedly connected to the lower surface of the cylinder 802. The limiting plate 810 slides in the first groove 801. The projector body 4 is fixedly connected to the lower surface of the limiting plate 810. The mounting holes allow the user to use screws to firmly install the fixing plate on the ceiling or bracket.
[0037] Reference Figure 3-6A first limiting plate 607 is fixedly connected to the rear end of the first spring 606. A limiting post 608 is fixedly connected to the middle of the first limiting plate 607. The first limiting plate 607 slides within the first slot 605. By sliding within the first slot, the limiting plate can only move along the direction of the slot, thus preventing offset or rotation in other directions. The first spring 606 is sleeved on the outside of the limiting post 608. The outer wall of the rear end of the limiting post 608 passes through the first slot 605 and the placement plate 604 in sequence and is snapped into the multi-hole disk 603. The spring sleeve provides an axis for the limiting post. The guide post 608 ensures stable and unbiased movement, and its rear end is engaged with the multi-hole disk, enabling quick and reliable locking of the projector's horizontal angle at multiple positions. The front end of the guide post 608 passes through the first slot 605 to the outside of the placement plate 604 and is fixedly connected to a handle 609. The handle allows the user to easily pull the projector out of the holes in the multi-hole disk. Multiple limit blocks 805 are evenly fixedly connected to the lower end of the outer wall of the cylinder 802. The side of each limit block 805 furthest from the center of the cylinder 802 is slidably connected to the inner wall of the first groove 801. The limit blocks are positioned within the first groove... The wall sliding mechanism ensures that the limiting block can only slide in a straight line or arc along the path specified by the inner wall of the first groove, preventing unnecessary offset or rotation under force. The second spring 808 is fixedly connected to a second limiting plate 809 on the side near the center of the cylinder 802. A slider 806 is fixedly connected to the side of the second limiting plate 809 near the center of the cylinder 802. The second limiting plate 809 slides within the second slot 807. This sliding within the second slot allows the user to move the block to different positions as needed. The slider 806 is also fixedly connected to the side near the center of the cylinder 802. The slide block passes through the second slot 807 and enters the first groove 801, engaging with the second groove 804. The slide block, located near the center of the cylinder, passes through the second slot and enters the first groove, engaging with it. This design provides crucial linkage and locking. A third spring 803 is fixedly connected to the center of the upper surface of the limiting plate 810. The upper end of the third spring 803 passes through the cylinder 802 and fits tightly against the top surface of the first groove 801. When the user adjusts the projector angle, the third spring is compressed. Once released, the spring force pushes the relevant components to move, automatically returning them to the preset initial position or engaging with the nearest positioning point, achieving automatic reset and precise positioning.
[0038] Working principle: First, the device is fixed to the ceiling by bolts through the mounting holes 5 at the four corners of the fixing plate 1, forming a stable support base. Second, when tilt and rotation adjustment is required, the user pulls the handle 609 outward to disengage the limiting post 608 from the snap-fit hole of the multi-hole plate 603. At this time, the connecting post 602 is unlocked, and the connecting shaft 601 inside the U-shaped plate 3 can drive the projector body 4 to rotate horizontally. After adjustment, the handle 609 is released, and the first spring 606 pushes the first limiting plate 607 to re-insert the limiting post 608. The corresponding holes of the perforated disk 603 are fixed. Next, when the projector body 4 is pressed down, the cylinder 802 slides in the first groove 801 and compresses the third spring 803. At the same time, the slider 806 is squeezed and compressed back into the second slot 807 and disengages from the second groove 804. At this time, the limiting block 805 can rotate around the inner wall of the first groove 801. Finally, after adjusting to the target angle, the pressure is released, the third spring 803 rebounds and the cylinder 802 is reset. The second spring 808 pushes the slider 806 into the adjacent second groove 804 to achieve angle locking.
[0039] 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 specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific 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.
