Technical Field

[0001] This utility model belongs to the field of decorative painting technology, and in particular relates to a decorative painting support base. Background Technology

[0002] Decorative paintings are decorative and artistic paintings that are typically used for interior decoration and to beautify spaces.

[0003] Since decorative paintings are generally a combination of paper and frame, they must normally be fixed to the wall or supported by a stand. However, current stands are not convenient for adjusting the tilt of the decorative painting and are rather rigid when placed on a table, lacking versatility. Therefore, the market urgently needs to develop a decorative painting stand to help people solve the existing problems. Utility Model Content

[0004] The purpose of this utility model is to provide a decorative painting support to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A decorative painting support base includes a base, an adjustment plate slidably connected to the upper surface of the base, the adjustment plate having a "C" shaped structure, and a fixing frame provided at the end of the adjustment plate, an angle adjustment mechanism for adjusting the angle of the adjustment plate being provided between the base and the adjustment plate, an installation cavity being provided on the surface of the fixing frame, the top of the installation cavity having an open structure, and a pressure plate being provided at the top of the fixing frame.

[0006] Preferably, the upper surface of the base is provided with an arc-shaped surface that matches the adjustment plate, and the base is a hollow structure.

[0007] Preferably, the surface of the arc-shaped surface is provided with two symmetrically distributed trapezoidal grooves, which are arranged along the path direction of the arc-shaped surface. The back of the adjusting plate is provided with two trapezoidal plates corresponding to the trapezoidal grooves. The size of the trapezoidal plates matches the size of the trapezoidal grooves, and the trapezoidal plates are slidably connected to the trapezoidal grooves.

[0008] Preferably, the angle adjustment mechanism includes a connecting shaft, a fixed seat is provided at the middle part of the surface of the arc-shaped surface, the middle part of the connecting shaft is rotatably connected to the fixed seat, and gears are sleeved at both ends of the connecting shaft. Two symmetrically distributed racks are provided on the surface of the adjustment plate along its path direction. The gears and racks are rolledly connected and mesh with each other. A knob is provided at one end of the connecting shaft.

[0009] Preferably, the middle part of the surface of the adjustment plate is provided with an arc-shaped opening along its path direction, and the width of the arc-shaped opening is greater than the length of the fixed base.

[0010] Preferably, the left side and bottom of the fixing frame are provided with a retaining edge, and the bottom of the pressure plate is provided with a protrusion whose size matches the mounting cavity.

[0011] Preferably, the top of the fixed frame is provided with a movable cavity, the bottom of the pressure plate is provided with a limiting plate that slides up and down with the movable cavity on one side of the protrusion, and a plurality of springs are provided between the limiting plate and the bottom inner wall of the movable cavity at equal intervals.

[0012] The decorative painting support of this utility model has the following advantages: 1. This utility model allows for the adjustment of the tilt angle of the fixed frame by rotating a knob to make the connecting shaft rotate, which in turn drives two gears to rotate. These gears then drive two racks to rotate around the center of the adjusting plate, which in turn rotates around its own center. This achieves the adjustment of the tilt angle of the fixed frame. Furthermore, the use of gears and racks to adjust the tilt angle of the fixed frame makes the angle adjustment more precise and convenient. This solves the problem that current support bases are not convenient for adjusting the tilt of decorative paintings and are relatively rigid and lack versatility when placed on a table. It is highly practical.

[0013] 2. When installing the decorative painting frame, pull the pressure plate by hand, then insert the painting frame into the mounting cavity from the right side. Release the hand that pulled the pressure plate, and under the tension of the spring, the pressure plate moves downward, causing the protrusion to engage with the top of the mounting cavity and contact the top of the painting frame. This achieves a tight fit against the top of the painting frame, fixing it in place and effectively preventing the painting frame from becoming loose. Attached Figure Description

[0022] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a decorative painting support base according to this utility model.

[0023] like Figure 1-5 As shown, a decorative painting support of this utility model includes a base 1, an adjustment plate 2 slidably connected to the upper surface of the base 1, the adjustment plate 2 having a "C" shaped structure, an arc-shaped surface 15 matching the adjustment plate 2 on the upper surface of the base 1, and the base 1 having a hollow structure. The adjustment plate 2 and the arc-shaped surface 15 are at the same center, so that when the angle adjustment mechanism drives the adjustment plate 2 to adjust the angle, the adjustment plate 2 can always slide on the arc-shaped surface 15, so that the arc-shaped surface 15 provides support for the adjustment plate 2. The surface of the arc-shaped surface 15 is provided with two symmetrically distributed trapezoidal grooves 16. The trapezoidal grooves 16 are arranged along the path direction of the arc-shaped surface 15. The back of the adjustment plate 2 is provided with two trapezoidal plates 9 corresponding to the trapezoidal grooves 16. The size of the trapezoidal plates 9 matches the size of the trapezoidal grooves 16, and the trapezoidal plates 9 and the trapezoidal grooves 16 are slidably connected. Through the cooperation between the trapezoidal plates 9 and the trapezoidal grooves 16, the adjustment plate 2 can be firmly connected to the base 1, which improves the stability of the structure and at the same time limits the adjustment plate 2.

[0024] A fixing frame 3 is provided at the end of the adjusting plate 2. An angle adjustment mechanism for adjusting the angle of the adjusting plate 2 is provided between the base 1 and the adjusting plate 2. The angle adjustment mechanism includes a connecting shaft 10. A fixing seat 11 is provided at the middle part of the surface of the arc-shaped surface 15. The middle part of the connecting shaft 10 is rotatably connected to the fixing seat 11. Gears 12 are sleeved at both ends of the connecting shaft 10. Two symmetrically distributed racks 8 are provided on the surface of the adjusting plate 2 along its path direction. The gears 12 and racks 8 are rolled and meshed with each other. A knob 13 is provided at one end of the connecting shaft 10. The connecting shaft 10 and the fixing seat are connected. A damping structure is provided between the connecting shaft 10 and the fixed seat 11 to increase the friction between them, making the connecting shaft 10 less prone to rotation. By rotating the knob 13, the connecting shaft 10 rotates, which in turn drives the two gears 12 to rotate. These gears 12 then drive the two racks 8 to rotate around the center of the adjusting plate 2, thus allowing the adjusting plate 2 to rotate around its own center. This allows for adjustment of the tilt angle of the fixed frame 3. Adjusting the tilt angle of the fixed frame 3 via the gears 12 and racks 8 makes angle adjustment more precise, convenient, and practical. An arc-shaped opening 7 is provided in the middle of the surface of the adjusting plate 2 along its path direction. The width of the arc-shaped opening 7 is greater than the length of the fixed seat 11. The arc-shaped opening 7 prevents interference between the adjusting plate 2 and the fixed seat 11 during movement.

[0025] The surface of the fixed frame 3 is provided with a mounting cavity 4, the top of the mounting cavity 4 is an open structure, and a pressure plate 6 is provided at the top of the fixed frame 3. The left side and bottom of the fixed frame 3 are provided with a retaining edge 5, and the bottom of the pressure plate 6 is provided with a protruding strip 14 whose size matches the mounting cavity 4. The retaining edge 5 allows the frame of the decorative painting to be wrapped inside the mounting cavity 4, which plays a good role in limiting the position of the decorative painting frame. The top of the fixed frame 3 is provided with a movable cavity 17. The bottom of the pressure plate 6 is located on one side of the protrusion 14 and is provided with a limiting plate 18 that slides up and down with the movable cavity 17. Multiple springs 19 are evenly distributed between the limiting plate 18 and the bottom inner wall of the movable cavity 17. When installing the decorative painting frame, pull the pressure plate 6 by hand, and then insert the painting frame into the mounting cavity 4 from the right side. Then release the hand that pulled the pressure plate 6. Under the pulling force of the springs 19, the pressure plate 6 moves downward, so that the protrusion 14 is inserted into the top of the mounting cavity 4 and contacts the top of the painting frame, thereby pressing the top of the painting frame and fixing the painting frame, which can effectively prevent the painting frame from loosening.

[0026] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model.
