Technical Field

[0001] This utility model relates to the technical field of tilt adjustment mechanism, specifically a picture frame tilt adjustment mechanism. Background Technology

[0002] A picture frame is a structure assembled from four borders, primarily used to hold pictures or photographs to protect and display artwork, enhancing its expressiveness. Picture frames are typically made of materials such as wood, plastic, metal, and glass. As decorative items or handicrafts, picture frames are indispensable in daily life, often used to hold pictures or photographs in place to enhance their effect, facilitate carrying or display, and protect the artwork or photograph itself. With technological advancements, the materials and designs of picture frames have become increasingly diverse. In exhibition halls or homes, picture frames are usually hung on walls for display and easy viewing.

[0003] In existing technologies, picture frames are typically fixed to the wall using nails or similar devices to ensure they fit snugly. However, for frames mounted high up, this makes it difficult to adjust the tilt angle during use, hindering the viewer's viewing experience and compromising usability. Therefore, we propose a picture frame tilt adjustment mechanism. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a picture frame tilt adjustment mechanism. This solves the problem that when picture frames are hung on the wall, they are usually fixed to the wall with nails or similar fasteners. However, for picture frames at higher positions, it is not convenient to adjust the tilt angle of the frame during use because they are close to the wall, which makes it inconvenient for viewers to view the frame, affects the viewing experience, and makes the frame inconvenient to use.

[0036] 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.

[0037] Please see Figures 1-6 This utility model provides a technical solution:

[0038] A picture frame tilt adjustment mechanism includes a fixed plate 1, a sliding plate 14 slidably connected inside the fixed plate 1, a rotating rod 13 rotatably connected at equal intervals to one side of the sliding plate 14, support blocks 11 symmetrically fixedly connected to one side of the fixed plate 1, a rotating shaft 12 rotatably connected between the two support blocks 11, an angle adjustment plate 2 fixedly connected to the outside of the rotating shaft 12, the rotating rod 13 rotatably connected to the angle adjustment plate 2, a sliding seat 23 symmetrically slidably connected inside the angle adjustment plate 2, a limit plug 22 equidistantly fixedly connected to one side of the sliding seat 23, the limit plug 22 slidably connected to the angle adjustment plate 2, a display picture frame 3 is provided on one side of the angle adjustment plate 2, a fixed block 31 symmetrically fixedly connected to one side of the display picture frame 3, a limit slot 32 for cooperating with the limit plug 22 is provided equidistantly inside the fixed block 31, and an adjustment mechanism 4 for cooperating with the sliding plate 14 is provided inside the fixed plate 1; the adjustment mechanism 4 includes a lead screw 46, the lead screw 46 is rotatably connected inside the fixed plate 1, and the sliding plate 14 is threadedly connected to the lead screw 46.

[0039] In this solution, the fixing plate 1 is installed on the wall with bolts. When the tilt of the display frame 3 needs to be adjusted, the rotation of the lead screw 46 drives the sliding plate 14 to move. The movement of the sliding plate 14 drives the two sets of rotating rods 13 to rotate. The rotation of the rotating rods 13 drives the angle adjustment plate 2 to rotate, thereby adjusting the tilt of the display frame 3 and making it easier for viewers to view the display frame 3. The sliding seat 23 drives the limiting block 22 to move and disengage from the limiting slot 32, thereby releasing the locking state of the fixing block 31 and making it easy to remove and replace the display frame 3. The operation is convenient.

[0040] like Figures 1-2 As shown: In this scheme, the inner wall of the fixed plate 1 is symmetrically fixedly connected with the limiting slide rod 45, and the sliding plate 14 is slidably connected to the limiting slide rod 45; the inside of the fixed plate 1 is rotatably connected with the transmission shaft 44, one end of the transmission shaft 44 is fixedly connected with the second bevel gear 43, and the outer side of the lead screw 46 is fixedly connected with the first bevel gear 42 that cooperates with the second bevel gear 43; the end of the transmission shaft 44 away from the second bevel gear 43 is fixedly connected with the operating knob 41, and the outer side of the operating knob 41 is fixedly connected with anti-slip protrusions at equal intervals.

[0041] In this design, the anti-slip protrusions increase friction, facilitating the rotation of the operating knob 41. The knob 41 drives the transmission shaft 44 to rotate, which in turn drives the second bevel gear 43. The second bevel gear 43, through the first bevel gear 42, drives the lead screw 46 to rotate. The rotation of the lead screw 46 causes the sliding plate 14 to move. The limiting slide bar 45 limits the movement of the sliding plate 14, preventing it from shifting during movement.

[0042] like Figures 4-6 As shown: In this scheme, the inner wall of the angle adjustment plate 2 is symmetrically and fixedly connected with limit rods 25, and the sliding seat 23 is slidably connected to the limit rods 25; the interior of the angle adjustment plate 2 is symmetrically provided with placement grooves 21 that cooperate with the fixed block 31; a connecting rod 27 is equidistantly rotatably connected to one side of the sliding seat 23, and a connecting shaft 28 is equidistantly rotatably connected to the interior of the angle adjustment plate 2, with a connecting rod 24 fixedly connected to one end of the connecting shaft 28, and the connecting rod 27 and the connecting rod 24 rotatably connected; a worm gear 29 is fixedly connected to the outer side of the connecting shaft 28, and a rotating shaft 26 is rotatably connected to the interior of the angle adjustment plate 2, with a worm gear cooperating with the worm gear 29 fixedly connected to the outer side of the rotating shaft 26 at equal intervals, and a handle is fixedly connected to one end of the rotating shaft 26.

[0043] In this design, the placement slot 21 can be used in conjunction with the fixing block 31 to facilitate the installation and fixing of the display frame 3. The handle drives the rotating shaft 26 to rotate, and the rotating shaft 26 drives the worm wheel 29 to rotate through the worm gear on its outer side, thereby driving the connecting shaft 28 to rotate. The connecting shaft 28 drives the connecting rod 24 to rotate, and the rotation of the connecting rod 24 drives the connecting rod 27 to rotate. The rotation of the connecting rod 27 drives the sliding seat 23 to move. The limiting rod 25 can limit the movement of the sliding seat 23 to prevent the sliding seat 23 from deviating during movement.

[0044] Working principle:

[0045] In use, the fixing plate 1 is installed on the wall with bolts. When it is necessary to adjust the tilt of the display frame 3, the operation knob 41 is turned. The operation knob 41 drives the second bevel gear 43 to rotate through the transmission shaft 44. The second bevel gear 43 drives the lead screw 46 to rotate through the first bevel gear 42. The rotation of the lead screw 46 drives the sliding plate 14 to move. The movement of the sliding plate 14 can be limited by the setting of the limiting slide rod 45 to prevent the sliding plate 14 from deviating during movement.

[0046] The movement of the sliding plate 14 causes the two sets of rotating rods 13 to rotate, which in turn causes the angle adjustment plate 2 to rotate, thereby adjusting the tilt of the display frame 3 for easy viewing. When the display frame 3 needs to be disassembled and replaced, the handle at one end of the rotating shaft 26 is turned, which causes the rotating shaft 26 to rotate. The rotating shaft 26 drives the worm wheel 29 to rotate through the worm gear on its outer side. The worm wheel 29 drives the connecting rod 24 to rotate through the connecting shaft 28. The rotation of the connecting rod 24 drives the connecting rod 27 to rotate, and the rotation of the connecting rod 27 drives the sliding seat 23 to move.

[0047] The movement of the sliding seat 23 can be limited by the setting of the limiting rod 25 to prevent the sliding seat 23 from deviating during movement. The sliding seat 23 drives the limiting block 22 to move and disengage from the limiting slot 32, thereby releasing the locking state of the fixing block 31, making it convenient to remove the display frame 3 for replacement. The operation is convenient.
