The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] See also Figures 1 to 4 A multifunctional adjustment bracket according to an embodiment of the utility model includes: a support frame 100, wherein the support frame 100 is provided with a slide groove 121 extending in a vertical direction; a slider assembly 200, which is slidably and lifted in the slide groove 121, and the slider assembly 200 is provided with an elastic mechanism 300 that stabilizes the cantilever after being lifted and lowered relative to the slide groove 121; a cantilever 400, wherein one end of the cantilever 400 is provided with a rotating member 410 that can be rotatably connected to the slider assembly 200 around a horizontal axis, and the other end is provided with a connecting member 420 for installing a projector; wherein the elastic mechanism 300 can act on the rotating member 410 to stabilize the cantilever 400 after being rotated relative to the slider assembly 200.

[0033] When in use, the multifunctional adjustment bracket of the above structure mounts the projector on the connecting piece 420 of the cantilever 400. When the cantilever 400 is lifted or pressed down, the slider assembly 200 can be moved up and down along the slide groove 121 to adjust the projection height of the projector. When the cantilever 400 is rotated, the rotating piece 410 can be rotated relative to the slider assembly 200 to adjust the head-up angle of the projector. The elastic mechanism 300 acts on the slider assembly 200 and the rotating piece 410 at the same time to synchronously stabilize the projection angle and projection height of the projector, and the adjustment method is very convenient. Moreover, when transportation is required, the cantilever 400 can be lowered to close to the bottom of the support frame 100, which is conducive to reducing the packaging size and reasonably arranging the stacking position during packaging.

[0034] It should be noted that when the output end of the projector is facing vertically upward to project the image onto the ceiling, the size of the projected image can be adjusted by raising and lowering the position of the cantilever 400; and when the projected wall is inclined, if the height position of the projector is limited, even if the output end of the projector is perpendicular to the projected wall, the projected image may not be fully projected onto the inclined wall. This problem can be solved by raising and lowering the height position of the projector.

[0035] See also Figure 2 and Figure 4 In some embodiments of the utility model, the slider assembly 200 includes two clamping blocks 210 arranged face to face, the rotating member 410 is located between the two clamping blocks 210, the elastic mechanism 300 includes a pad 310 and a first spring member 320, the pad 310 is located between the side of the clamping block 210 away from the rotating member 410 and the slide groove 121, and the two ends of the first spring member 320 respectively abut against the pad 310 and the clamping block 210 to drive the two clamping blocks 210 to clamp the rotating member 410 together and drive the pad 310 to abut against the slide groove 121 to limit the upward and downward movement of the slider assembly 200. It is understandable that under the action of the first spring member 320, the two clamping blocks 210 clamp the rotating member 410, so that the projector on the cantilever 400 is not easy to rotate around the horizontal axis, thereby stabilizing the projection angle of the projector. At the same time, the pad 310 elastically abuts against the inner wall of the slide slot 121 under the action of the first spring member 320, and relies on the friction between the pad 310 and the slide slot 121 to prevent the projector on the cantilever 400 from falling due to gravity, thereby stabilizing the height position of the projector. When the height position of the projector needs to be adjusted, an external force that overcomes the friction between the pad 310 and the slide slot 121 needs to be applied to achieve the lifting and lowering movement of the projector. When the angular position of the projector needs to be adjusted, a torque that overcomes the clamping force of the two clamping blocks 210 on the rotating member 410 needs to be applied to achieve the rotation of the projector.

[0036] It can be understood that the above functions can be achieved by configuring one of the clamping blocks 210 with a first spring member 320 and a pad 310. However, in order to achieve a more stable limiting effect, in some embodiments of the utility model, a pad 310 is arranged between the side of each clamping block 210 that is away from the rotating member 410 and the slide groove 121. In order to prevent the first spring member 320 from twisting and affecting the reliability of the elastic restoring force, a hole 211 is provided at the upper and lower ends of the side of each clamping block 210 that is away from the rotating member 410. The pad 310 is provided with a plug post 311 that extends into the hole 211 one by one on the side wall of the corresponding clamping block 210, and the plug posts 311 are all penetrated by the first spring member 320 located in the hole 211.

[0037] See also Figure 2 and Figure 4 In some embodiments of the utility model, the rotating member 410 includes a cylindrical portion 411 arranged around the horizontal axis, and the outer peripheral wall of the cylindrical portion 411 is provided with a plurality of first tooth-shaped grooves 412 distributed circumferentially, and the side of the clamping block 210 away from the backing plate 310 is provided with an arc concave surface 212 matched with the cylindrical portion 411, and the arc concave surface 212 is formed with a plurality of second tooth-shaped grooves 213 meshing with the first tooth-shaped grooves 412, and when the first spring member 320 drives the second tooth-shaped grooves 213 to be combined with the first tooth-shaped grooves 412, there is an active gap between the backing plate 310 and the corresponding clamping block 210. It can be understood that the reliability of preventing the rotating member 410 from rotating around the horizontal axis by relying solely on the friction between the rotating member 410 and the clamping block 210 is insufficient, and greater rotation resistance can be obtained by meshing the first tooth-shaped grooves 412 and the second tooth-shaped grooves 213. In addition, when the angle position of the projector needs to be adjusted, the separation of the first tooth-shaped groove 412 and a certain second tooth-shaped groove 213 will cause the two clamping blocks 210 to move away from each other, and the setting of the movable gap can avoid interference.

[0038] In the case where the projector is heavy, it is necessary to increase the rotation resistance of the rotating member 410 and the resistance to prevent the slider assembly 200 from descending, see Figures 1 to 3 In some embodiments of the present invention, the support frame 100 is threadedly connected with a threaded push rod 500 which can be pressed against the side of the rotating member 410 away from the cantilever 400. Figure 5 The cantilever 400 in this embodiment is L-shaped and can support the bottom and sides of the projector.

[0039] See also Figure 2 and Figure 3 In some embodiments of the utility model, a rectangular slot 413 is provided in the middle of the cylindrical portion 411 along its axial direction, a rectangular plug plate 430 is provided at one end of the cantilever 400 away from the connecting member 420 and inserted into the rectangular slot 413, a through hole 414 is provided through the cylindrical portion 411 along its radial direction, the rectangular plug plate 430 has a threaded through hole directly opposite to the through hole 414, and a bolt passes through the through hole 414 and is connected to the threaded through hole to fix the rectangular plug plate 430 to the rectangular slot 413. In this embodiment, the cantilever 400 is a sheet with a relatively thin wall thickness, and the rectangular plug plate 430 is a part of the sheet. The torque of the rotating cantilever 400 can be transmitted by the cooperation of the rectangular plug plate 430 and the rectangular slot 413, and the bolt passes through the through hole 414 and is connected to the threaded through hole to prevent the rectangular plug plate 430 from being withdrawn from the rectangular slot 413, thereby playing a role of fixed installation.

The desktop flat panel 110 is used to be placed on a desktop or other placement plane, the cantilever 400 is lifted and moved relative to the column 120 to adjust the height position of the projector, and the vertical clearance groove 122 can avoid the lifting and moving cantilever 400, and the above support frame 100 has a simple structure and a small number of parts.

It should be noted that under the action of the second spring member 330, the end face of the cylinder abuts against the inner wall of the slide groove 121 to form a large friction force, and the slider assembly 200 can stabilize the height position of the projector by using the friction force, and the friction force also has the function of preventing the cylinder from rotating relative to the cylindrical groove 220, thereby stabilizing the angular position of the projector.

[0042] See also Figure 8 In the case where the projector is heavier, it is necessary to increase the rotational resistance of the rotating member 410 and the resistance to preventing the slider assembly 200 from descending. In some embodiments of the utility model, the side of the column 120 is provided with a locking screw 600 coaxial with the horizontal axis, and the locking screw 600 can be passed through the slider assembly 200 and the cylinder. The middle of the cylinder is provided with a nut member 700 that cooperates with the locking screw 600. The locking screw 600 rotates relative to the nut member 700 so that the head of the locking screw 600 abuts against the outer wall of the column 120 to prevent the cylinder from rotating and the slider assembly 200 from sliding.
