Description

Technical Field

[0001] The utility model relates to the technical field of billboard processing, in particular to an assembly turntable. Background Art

[0002] When processing billboards, such as processing dual-screen elevator displays, the outer shell needs to be processed first, and then the display screen is fixed inside the outer shell. At present, when installing the display screen, the operator places the outer shell flat on the processing table, and then installs the display screen, controller, circuit board, etc. Since the posture of the outer shell cannot be adjusted after placement, it brings many inconveniences to the installation operation, which seriously affects the production efficiency of the dual-screen display billboard. Utility Model Content

[0003] The utility model provides a turntable for assembly, so as to solve the above-mentioned deficiencies of the prior art, solve the problem of inconvenient assembly of electronic display billboards, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

[0005] An assembly turntable includes a bottom plate, a lower turntable is rotatably provided on the bottom plate, a turntable is hinged on the upper end of the lower turntable, the lower turntable can rotate around the bottom plate in all directions, and the turntable can rotate in pitch around the lower turntable. A pad is installed on the upper end of the turntable, two pairs of rotating columns are rotatably provided on the pad, and an upper clamp is provided on the upper end of the rotating column. The pad supports the outer shell, and the upper clamp provided on the rotating column ensures that the outer shell is stably located on the pad. The pad can also rotate in all directions and in pitch, so as to facilitate the assembly operation of the electronic display billboard.

[0006] Furthermore, a pair of pads are provided at one end of the upper wall of the pad, and the pads support the lower wall of the shell so that the shell does not contact the pad, thereby avoiding scratches on the fixed display screen.

[0007] Furthermore, a pair of limit blocks are provided at the other end of the upper wall of the pad, and an angle groove is provided on the limit block, and the bottom of the angle groove is at the same height as the upper wall of the pad. The angle groove on the limit block can further limit one end and both sides of the shell, thereby improving the positioning effect.

[0008] Further, a pair of kidney-shaped holes are provided on the backing plate. Connecting screws are inserted through the kidney-shaped holes. A concave plate is provided at the lower end of the connecting screw, and a limiting end plate is provided at the upper end of the connecting screw. A movable end plate is provided at the outer end of the concave plate. A pair of through rods are provided on the movable end plate. End fixing plates are sleeved on the through rods. The end fixing plates are installed at the end of the backing plate. Springs are sleeved on the through rods, and the springs are located between the end fixing plates and the movable end plate. Through the provided limiting end plate, when the outer shell is placed, it can be tightly pressed against one end of the outer shell under the action of the spring, and then the outer shell is positioned through the corner groove. By this positioning method, the problem of the outer shell moving in position during the adjustment of the outer shell posture can be avoided.

[0009] Further, an inward extending block is provided on the inner wall of the limiting end plate to prevent the existence of the cushion block from affecting the positioning operation of the limiting end plate.

[0010] Further, a pair of outward extending support plates are respectively provided on both sides of the concave plate. Kidney-shaped action holes are provided in the outward extending support plates. Inner through rods are inserted through the kidney-shaped action holes. A connecting plate is provided at the upper end of the inner through rod, and the other end of the connecting plate is provided at the lower end of the rotating column. This solution can utilize the movement of the limiting end plate to make the rotating column rotate, thereby facilitating the limitation of the upper side of the outer shell through the upper clamping plate.

[0011] The advantages of the above technical solution are as follows:

[0012] The utility model solves the problem that the posture adjustment is inconvenient during the installation operation of the double-screen advertising display. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the drawings.

[0016] Figure 3 Shows the three-dimensional structure of one of the embodiments Figure 3 . DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] As Figures 1 to 3As shown in the figure, a turntable for assembly includes a bottom plate 1. A lower turntable 2 is rotatably provided on the bottom plate 1. The upper end of the lower turntable 2 is hinged with a turntable plate 20. A cushion plate 3 is installed at the upper end of the turntable plate 20. Two pairs of rotating columns 4 are rotatably provided on the cushion plate 3. An upper clamping plate 40 is provided at the upper end of the rotating column 4. One end of the upper wall of the cushion plate 3 is provided with a pair of cushion blocks 33. The other end of the upper wall of the cushion plate 3 is provided with a pair of limit blocks 31. An angular groove 32 is opened on the limit block 31. The bottom of the angular groove 32 is at the same height as the upper wall of the cushion block 33.

[0018] A pair of kidney-shaped holes 30 are opened on the cushion plate 3. A connecting screw 43 is passed through the kidney-shaped holes 30. A concave plate 46 is provided at the lower end of the connecting screw 43. A limit end plate 44 is provided at the upper end of the connecting screw 43. A movable end plate 47 is provided at the outer end of the concave plate 46. A pair of through rods 48 are provided on the movable end plate 47. A end fixing plate 6 is sleeved on the through rod 48. The end fixing plate 6 is installed at the end of the cushion plate 3. A spring 49 is sleeved on the through rod 48. The spring 49 is located between the end fixing plate 6 and the movable end plate 47. An inner extending block 45 is provided on the inner wall of the limit end plate 44. A pair of outer extending support plates 50 are respectively provided on both sides of the concave plate 46. A kidney-shaped acting hole 51 is opened on the outer extending support plate 50. An inner through rod 42 is passed through the kidney-shaped acting hole 51. A connecting plate 41 is provided at the upper end of the inner through rod 42. The other end of the connecting plate 41 is provided at the lower end of the rotating column 4.

[0019] In the assembly of the dual-screen advertising display in this embodiment, first, the operator places the outer shell in the cushion block 33 and the angular groove 32. Before placing, the limit end plate 44 is pulled outwards. And when pulling out the limit end plate 44 outwards, the inner through rod 42 on it will be pulled through the outer extending support plate 50 and the kidney-shaped acting hole 51 on it, so that the rotating column 4 rotates, and finally the upper clamping plate 40 rotates outwards.

[0020] Then the operator places the outer shell in the cushion block 33 and the angular groove 32, and then releases the outward pulling force on the limit end plate 44. Then the limit end plate 44 will act on the inner through rod 42 through the kidney-shaped acting hole 51 under the action of the spring 49, so that the rotating column 4 rotates for reset, and finally the outer shell is constrained and limited by the upper clamping plate 40.

[0021] Finally, the operator rotates the azimuth angle and pitch angle of the outer shell as needed, and performs the assembly operation of each component.

[0022] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention also intends to include these modifications and variations.
