Description

Technical Field

[0001] This utility model belongs to the technical field of projector accessories, and relates to a projector mounting bracket, particularly a projector mounting bracket with a horizontal correction structure. Background Technology

[0002] A projector is an optical instrument that uses optical elements to magnify the outline of a workpiece and project it onto a screen. It can use transmitted light for outline measurement, or reflected light to measure the surface shape of a hole and observe the surface of a part. Projectors are widely used in public places such as conference rooms, exhibition halls, and classrooms to project various flat images. When using a projector, it needs to be installed and fixed with a mounting bracket to facilitate projection playback.

[0003] A search revealed a multimedia teaching projector with an auxiliary correction structure disclosed in Chinese patent literature [Application No.: CN202022486117.9; Publication No.: CN214332107U]. This multimedia teaching projector includes a base, a correction mechanism located above the base, and a projector body located on the correction mechanism. A rotating rod is fixedly connected to the bottom surface of the correction mechanism, and the bottom end of the rotating rod is rotatably connected to the top surface of the base. An opening is provided on the top surface of the correction mechanism, and the projector body is placed inside the opening. A connecting seat is fixedly provided on the bottom surface of the opening, and the bottom surface of the projector body is fixedly connected to the connecting seat. Slide grooves are provided on both sides of the opening, and sliding strips matching the slide grooves are fixedly provided on both sides of the side walls of the projector body. The tail ends of the sliding strips are embedded in the slide grooves.

[0004] Although the multimedia teaching projector disclosed in this patent uses a rotating rod to drive the correction mechanism to rotate, allowing the direction of the projector body to be adjusted left and right, the correction mechanism can only adjust the projector horizontally from the bottom. When the projector is used in a suspended position, it cannot correct the horizontal position of the suspended projector, which makes the projector prone to tilting and shifting during suspended use, seriously affecting the projection effect of the projector. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a projector mounting bracket with a horizontal correction structure. The technical problem this utility model aims to solve is: how to conveniently achieve horizontal correction of a ceiling-mounted projector and facilitate users in adjusting the horizontal position of the ceiling-mounted projector.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A projector mounting bracket with a horizontal correction structure includes a side frame, a crossbar fixedly connected to the surface of the side frame, an adjusting rod internally telescopically connected to the end of the crossbar away from the side frame, a collar slidably sleeved on the end of the adjusting rod away from the crossbar, and a fixing frame fixedly connected to the bottom end of the collar, and a correction mounting assembly installed below the fixing frame.

[0008] The calibration mounting assembly includes a rotating rod rotatably connected to the bottom of the fixed frame. A side plate is fixedly connected to the outer wall of the rotating rod, and a calibration plate is fixedly installed on the outer surface of the side plate. A sliding column is slidably connected inside the calibration plate, and the sliding column is fixedly connected to the outer wall of the fixed frame.

[0009] The internal thread of the fixing frame is connected to a hand-tightening screw, and the bottom end of the hand-tightening screw is fixedly connected to a backing plate, and the bottom end of the backing plate is attached to the surface of the side plate.

[0010] The end of the calibration plate is connected to a telescopic mounting unit.

[0011] With the above structure, to achieve horizontal alignment of the projector after installation, a collar is fitted onto the outer wall of the adjusting rod. This allows the mounting bracket to be fixed to the outer wall of the adjusting rod via bolts, positioning grooves, and mounting holes, ensuring the collar's secure fixation. Simultaneously, a rotating rod is rotatably connected below the mounting bracket. A side plate is fixedly connected to the outer wall of the rotating rod, allowing the side plate to rotate at an angle below the mounting bracket. A correction plate is fixedly connected to the outer wall of the side plate, allowing the user to visually observe the horizontal angle of the side plate via a sliding column. Furthermore, a hand-tightening screw is threaded onto the top of the mounting bracket, allowing the user to use the screw at different positions to move the abutment downwards and press the side plate, achieving horizontal alignment. This facilitates horizontal adjustment of the projector and ensures a level performance during hoisting.

[0012] The calibration plate is arranged in an arc shape, and the center of the calibration plate coincides with the center of the rotating rod. The surface of the calibration plate is printed with scale lines.

[0013] The central axis of the sliding column coincides with the central axis of the correction plate.

[0014] With the above structure, the adjustment plate, under its arc-shaped action, causes the side plate to rotate synchronously with the adjustment plate as the rotating rod rotates. By sliding the sliding column inside the adjustment plate and fixing it to the outer wall of the mounting frame, the rotation angle of the side plate can be indicated by scale lines through the adjustment plate. This allows users to intuitively check the level of the projector bracket, which helps improve the installation effect of the projector.

[0015] The telescopic mounting unit includes a mounting plate that is telescopically connected to the end of a side plate. An adjustment groove is provided on the surface of the side plate, and a positioning screw is installed inside the adjustment groove. The bottom end of the positioning screw is threadedly connected to the mounting plate.

[0016] By adopting the above structure and setting telescopic mounting units at both ends of the side plate, different models of projectors can be precisely fixed at the bottom of the side plate through the mounting plate, which improves the applicability of the bracket and makes it easier to meet different installation needs. Moreover, the setting of adjustment groove and positioning screw ensures high stability and precision of the mounting plate's internal telescopic movement within the side plate.

[0017] The top of the adjusting rod is fixedly connected to a limiting block by a screw, and the limiting block is slidably connected to the surface of the crossbar. The surface of the crossbar is provided with a sliding track that can accommodate the sliding of the screw.

[0018] With the above structure, the setting of the limiting block and screws allows the adjusting rod to extend and retract stably inside the crossbar when the screws are not locked to the limiting block. Moreover, the limiting block is locked to the surface of the crossbar by the screws. The operation is simple and convenient, which helps to improve the installation applicability of the projector bracket.

[0019] The bottom end of the collar is fixedly connected to a support plate, and two support plates are symmetrically arranged about the central axis of the collar. The support plates are perpendicular to the collar and are located at the bottom end of the adjusting rod.

[0020] The tray has a through-hole for mounting, and a bolt is threaded into the hole. An adjusting rod is threaded into the top of the bolt, and a positioning groove is provided at the bottom of the adjusting rod to accommodate the bolt.

[0021] With the above structure, by fixing the support plates to both sides of the bottom end of the collar, the support plates can stably limit the movement of the collar at the bottom end when the collar moves along the outer wall of the adjusting rod under the perpendicular action of the support plates and the collar, ensuring the balance of the collar movement. Moreover, with the action of the mounting holes and positioning grooves, the bolts can be used to fix the fixing frame to any position on the outer wall of the adjusting rod through the mounting holes and positioning grooves, improving the fixing flexibility of the fixing frame. The structure is simple and easy to adjust.

[0022] Compared with the prior art, the projector mounting bracket with a horizontal correction structure of this utility model has the following advantages:

[0023] In this invention, by sliding a connecting collar on the outer wall of the adjusting rod, the collar can drive the correction and installation components to be fixed at different positions, ensuring the flexibility of the mounting bracket. Moreover, the setting of the correction and installation components allows users to intuitively see through the rotation angle of the side plate through the arc plate, facilitating horizontal observation of the installed projector. Furthermore, under the action of the hand-tightening screw, the abutment plate can perform horizontal correction of the side plate, ensuring the installation effect of the projector. The structure is simple, highly practical, and achieves precise horizontal correction of the projector during hoisting, ensuring the projection accuracy and convenient adjustment of the projector during hoisting.

[0029] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0030] Example

[0031] like Figures 1-3 As shown;

[0032] A projector mounting bracket with a horizontal correction structure includes a side frame 1, a crossbar 2, an adjusting rod 3, a limiting block 4, a slide rail 5, a collar 6, a fixing frame 7, a support plate 8, a mounting hole 9, a rotating rod 10, a side plate 11, a correction plate 12, a sliding column 13, a hand-tightening screw 14, a backing plate 15, a mounting plate 16, a positioning screw 17, an adjusting groove 18, and a positioning groove 19. The crossbar 2 is fixedly connected to the surface of the side frame 1. The adjusting rod 3 is internally telescopically connected to the end of the crossbar 2 away from the side frame 1. The top end of the adjusting rod 3 passes through... A limiting block 4 is fixedly connected by screws, and the limiting block 4 is slidably connected to the surface of the crossbar 2. A slide rail 5, which accommodates the sliding of the screw, is provided through the surface of the crossbar 2. Through the setting of the limiting block 4 and the screw, when the screw is not locked to the limiting block 4, the adjusting rod 3 can stably extend and retract inside the crossbar 2 via the screw and the limiting block 4. Furthermore, the limiting block 4 is locked to the surface of the crossbar 2 by the screws. This simple and convenient operation improves the applicability of the projector bracket installation. A collar 6 is slidably fitted onto the end of the adjusting rod 3 away from the crossbar 2. A support plate 8 is fixedly connected to the bottom end of the collar 6, and two support plates 8 are symmetrically arranged about the central axis of the collar 6. The support plates 8 and the collar 6 are distributed perpendicularly, and the support plates 8 are located at the bottom end of the adjusting rod 3. By fixing the support plates 8 to both sides of the bottom end of the collar 6, under the perpendicular action of the support plates 8 and the collar 6, when the collar 6 drives the fixing frame 7 to move on the outer wall of the adjusting rod 3, the support plates 8 can be stably limited at the bottom end of the collar 6, ensuring the balance of the movement of the collar 6. A mounting hole 9 is opened through the inside of the support plate 8, and a bolt is threaded inside the mounting hole 9. The top of the bolt is threaded to the adjusting rod 3, and a positioning groove 19 is opened at the bottom end of the adjusting rod 3 to accommodate the bolt installation. Under the action of the mounting hole 9 and the positioning groove 19, the bolt can fix the fixing frame 7 at any position on the outer wall of the adjusting rod 3 through the mounting hole 9 and the positioning groove 19, which improves the fixing flexibility of the fixing frame 7, and the structure is simple and easy to adjust.

[0033] Furthermore, to achieve horizontal alignment of the projector during installation, a mounting bracket 7 is fixedly connected to the bottom of the collar 6. A alignment mounting assembly is installed below the mounting bracket 7. Specifically, the alignment mounting assembly includes a rotating rod 10, which is rotatably connected to the bottom of the mounting bracket 7. A side plate 11 is fixedly connected to the outer wall of the rotating rod 10, and an alignment plate 12 is fixedly mounted on the outer surface of the side plate 11. The alignment plate 12 has an arc-shaped structure, and its center coincides with the center of the rotating rod 10. The surface of the alignment plate 12 is printed with scale lines. A sliding column 13 is slidably connected inside the alignment plate 12. The sliding column 13 is fixedly connected to the outer wall of the mounting bracket 7, and its central axis coincides with the central axis of the alignment plate 12. The arc shape of the alignment plate 12 causes the side plate 11 to rotate synchronously with the alignment plate 12 as the rotating rod 10 rotates. This is achieved by sliding the sliding column 13 inside the alignment plate 12. With the sliding column 13 fixedly connected to the outer wall of the fixed frame 7, the rotation angle of the side plate 11 by the sliding column 13 can be indicated by the scale line through the correction plate 12, which makes it convenient for users to intuitively test the level of the projector bracket and improve the installation effect of the projector. In addition, in order to facilitate the user to perform level correction after level test, a hand screw 14 is threadedly connected inside the fixed frame 7, and a stop plate 15 is fixedly connected to the bottom end of the hand screw 14. The bottom end of the stop plate 15 is attached to the surface of the side plate 11. By setting hand screws 14 on both sides of the side plate 11, the rotation of the hand screw 14 causes the hand screw 14 to drive the stop plate 15 at the bottom end to rise and fall. This allows the stop plate 15 to adjust the side plate 11 on one side of the side plate 11, which is convenient for the side plate 11 to be leveled under the fixed frame 7 by rotating the rod 10, thus achieving precise level correction of the side plate 11.

[0034] Furthermore, to improve the ease of installation for different projectors, a telescopic mounting unit is connected to the end of the calibration plate 12. Specifically, the telescopic mounting unit includes a mounting plate 16, which is telescopically connected to the end of the side plate 11. An adjustment groove 18 is provided on the surface of the side plate 11, and a positioning screw 17 is installed inside the adjustment groove 18. The bottom end of the positioning screw 17 is threadedly connected to the mounting plate 16. With this configuration, and the telescopic mounting units at both ends of the side plate 11, different models of projectors can be precisely fixed at the bottom end of the side plate 11 using the mounting plate 16. This improves the applicability of the bracket and facilitates meeting different installation needs. Moreover, the adjustment groove 18 and the positioning screw 17 ensure high stability and precision of the telescopic movement of the mounting plate 16 within the side plate 11.

[0035] The working principle of this utility model is as follows: During operation, the bracket is fixed to the wall by the side frame 1. The adjustment rod 3 extends and retracts within the crossbar 2, allowing the user to secure it using screws and the limiting block 4. This achieves stable adjustment of the adjustment rod 3 within the crossbar 2. Simultaneously, the adjustment groove 18 and the positioning screw 17 cause the mounting plate 16 to extend and retract at the outer end of the side plate 11, facilitating the fixing of the mounting plate 16 to different projectors at the top and ensuring the applicability of the bracket and projector. To achieve horizontal correction of the projector after installation, a collar 6 is fitted onto the outer wall of the adjustment rod 3, allowing the fixing frame 7 to be fixedly connected to the positioning groove 19 and mounting hole 9 via bolts. The outer wall of rod 3 is fixed, ensuring the fixing effect of collar 6 on the outer wall of adjusting rod 3. At the same time, under the action of rotating rod 10 connected to the bottom of fixed frame 7, the side plate 11 is fixedly connected to the outer wall of rotating rod 10, so that the side plate 11 can rotate at an angle below fixed frame 7. Under the action of correction plate 12 fixedly connected to the outer wall of side plate 11, the user can intuitively observe the horizontal angle of side plate 11 through sliding column 13. Moreover, by threading hand screw 14 above fixed frame 7, the user can drive the abutment plate 15 to move downward to squeeze side plate 11 by hand screwing the hand screw 14 at different positions, so that side plate 11 can be horizontally corrected, which facilitates the horizontal adjustment of projector and ensures the horizontal effect of projector during hoisting.
