Description

Technical Field

[0001] The utility model relates to the technical field of truss module structures, in particular to a truss module structure based on air columns. Background Art

[0002] The truss module structure is used for the construction of stage lights. The truss module structure is composed of a base, a square sleeve, a column, a cross frame, a pulley, a steel chain, a hook, and a hanging ring. When constructing stage lights, the square sleeve is inserted into the base so that the rollers on the square sleeve contact the round rod on the base. Then, the cross frame and the square sleeve are bolted and fixed. At the same time, the lights are installed on the cross frame. The steel chain is passed through the pulley on the column, and then the column and the base are bolted and fixed. The hook on the steel chain is connected to the hanging ring on the square sleeve. Then, the steel chain is manually lifted to raise the square sleeve and the cross frame. Finally, the square sleeve and the column are bolted and fixed, thus completing the construction of the stage lights.

[0003] The inventor found in daily work that when the truss module structure is in use, when installing and fixing the cross frame, the worker holds up the cross frame. After keeping the mounting holes on the cross frame and the mounting holes on the square sleeve horizontally and vertically aligned, bolts are inserted for fixation. Due to the long-term holding by the worker, the arm is prone to shaking, which may cause misalignment between the mounting holes and requires realignment, thus affecting the installation and fixation efficiency of the cross frame. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that in the actual use process, when installing and fixing the cross frame, the worker holds up the cross frame. After keeping the mounting holes on the cross frame and the mounting holes on the square sleeve horizontally and vertically aligned, bolts are inserted for fixation. Due to the long-term holding by the worker, the arm is prone to shaking, which may cause misalignment between the mounting holes and requires realignment, thus affecting the installation and fixation efficiency of the cross frame. A truss module structure based on air columns is proposed.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A truss module structure based on air columns, including a base, a column is arranged at the upper end of the base, a square sleeve is slidably connected to the surface of the column, a cross frame is arranged on one side of the square sleeve, pre-fixing components are arranged on both sides of the cross frame, a lifting component is arranged at the upper end of the base, the pre-fixing component includes a U-shaped plate arranged on one side of the cross frame, a pin is slidably inserted into the upper end of the U-shaped plate, and a positioning groove is opened at the upper end of the square sleeve.

[0006] The effects achieved by the above components are as follows: By setting the pre-fixing component, when installing and fixing the cross frame and the square sleeve, after the worker lifts and aligns the mounting holes on the cross frame and the square sleeve, then the U-shaped plate is clamped onto the cross frame, and the pin is inserted into the U-shaped plate and the positioning groove to limit the U-shaped plate, so as to hold up the cross frame, thereby avoiding the misalignment of the mounting holes caused by long-term manual holding.

[0007] Preferably, a lead screw is threadedly inserted on one side of the U-shaped plate, one end of the lead screw is rotatably connected to a limiting plate, and a limiting groove is formed on one side of the square sleeve.

[0008] The effect achieved by the above components is that by turning the lead screw, under the action of the limiting mechanism, the pushing limiting plate is made to snap into the limiting groove, thereby further limiting the U-shaped plate.

[0009] Preferably, an auxiliary rod is slidably inserted on one side of the limiting plate, and the auxiliary rod is fixed to the limiting plate.

[0010] The effect achieved by the above components is that by providing the auxiliary rod, the limiting plate is limited.

[0011] Preferably, a spring is fixedly connected to the lower end of the bolt pin, and the other end of the spring is fixed to the U-shaped plate.

[0012] The effect achieved by the above components is that by providing the spring, the bolt pin is limited.

[0013] Preferably, the lifting assembly includes a steel wire rope detachably connected to the upper end of the square sleeve, a pneumatic telescopic rod is installed at the upper end of the base, the other end of the steel wire rope is fixed to the pneumatic telescopic rod, and the steel wire rope penetrates through the column.

[0014] The effect achieved by the above components is that when it is necessary to lift the square sleeve, start the pneumatic telescopic rod (the air column in this case is the pneumatic telescopic rod, and the lifting is controlled by the telescopic force), so that the steel wire rope is pulled, thereby lifting the square sleeve, and thus avoiding manually lifting the square sleeve by pulling the iron chain.

[0015] Preferably, a pulley I is installed at the upper end of the base, and the steel wire rope is arranged below the pulley I.

[0016] The effect achieved by the above components is that by providing the pulley I, the steel wire rope is limited.

[0017] Preferably, a pulley II is installed above the column, and the steel wire rope is placed on the pulley II.

[0018] The effect achieved by the above components is that by providing the pulley II, it assists in pulling the steel wire rope.

[0019] In summary, the beneficial effects of the present utility model are:

[0020] In the present utility model, by providing a pre-fixing component, when installing and fixing the horizontal frame and the square sleeve, after the worker lifts and aligns the mounting holes on the horizontal frame and the square sleeve, then the U-shaped plate is snapped onto the horizontal frame, and the pin is inserted into the U-shaped plate and the positioning groove to limit the U-shaped plate, so as to lift the horizontal frame, thereby achieving the effect of avoiding the misalignment of the mounting holes caused by the worker's long-term lifting. This solves the problem that when installing and fixing the horizontal frame, after the worker holds the horizontal frame and keeps the mounting holes on the horizontal frame and the mounting holes on the square sleeve horizontally and vertically aligned, bolts are inserted for fixation. Due to the long-term holding by the worker, the arm is prone to shaking, which may cause the misalignment between the mounting holes and requires re-alignment, thus affecting the installation and fixing efficiency of the horizontal frame.

[0026] Refer to Figure 1 As shown, the present utility model provides a technical solution: A truss module structure based on air columns includes a base 1, a column 4 is arranged at the upper end of the base 1, a square sleeve 5 is slidably connected to the surface of the column 4, a horizontal frame 6 is arranged on one side of the square sleeve 5, pre-fixing components 2 are arranged on both sides of the horizontal frame 6, and a lifting component 3 is arranged at the upper end of the base 1.

[0027] Next, the specific settings and functions of the pre-fixing component 2 and the lifting component 3 will be specifically described.

[0028] Refer to Figure 2 and Figure 3As shown in the figure, in this embodiment: The pre-fixing component 2 includes a U-shaped plate 21 arranged on one side of the cross frame 6. A pin 22 is slidably inserted into the upper end of the U-shaped plate 21. A positioning groove 23 is opened at the upper end of the square sleeve 5. By setting the pre-fixing component 2, when installing and fixing the cross frame 6 and the square sleeve 5, the worker lifts the cross frame 6 and aligns the installation holes on the cross frame 6 and the square sleeve 5, and then snaps the U-shaped plate 21 onto the cross frame 6. The pin 22 is inserted into the U-shaped plate 21 and the positioning groove 23 to limit the U-shaped plate 21, so as to lift the cross frame 6, thereby avoiding the misalignment of the installation holes caused by the worker's long-term lifting. A screw rod 24 is threadedly inserted into one side of the U-shaped plate 21. One end of the screw rod 24 is rotatably connected to a limiting plate 27. A limiting groove 26 is opened on one side of the square sleeve 5. By turning the screw rod 24, under the action of the limiting mechanism, the limiting plate 27 is pushed into the limiting groove 26 to further limit the U-shaped plate 21. An auxiliary rod 25 is slidably inserted into one side of the limiting plate 27. The auxiliary rod 25 is fixed to the limiting plate 27. By setting the auxiliary rod 25, the limiting plate 27 is limited. The lower end of the pin 22 is fixedly connected to a spring 28. The other end of the spring 28 is fixed to the U-shaped plate 21. By setting the spring 28, the pin 22 is limited.

[0029] Referring to Figure 2 and Figure 4 As shown in the figure, in this embodiment: The lifting component 3 includes a steel wire rope 31 detachably connected to the upper end of the square sleeve 5. A pneumatic telescopic rod 32 is installed at the upper end of the base 1. The other end of the steel wire rope 31 is fixed to the pneumatic telescopic rod 32. The steel wire rope 31 passes through the column 4. When it is necessary to lift the square sleeve 5, the pneumatic telescopic rod 32 is started (in this case, the air column is the pneumatic telescopic rod 32, and the telescopic force controls the lifting and lowering), so that the steel wire rope 31 is pulled, thereby lifting the square sleeve 5, and thus avoiding the use of manual labor to lift the square sleeve 5 by pulling the iron chain. A pulley 33 is installed at the upper end of the base 1. The steel wire rope 31 is arranged below the pulley 33. By setting the pulley 33, the steel wire rope 31 is limited. A pulley 34 is installed above the column 4. The steel wire rope 31 is placed on the pulley 34. By setting the pulley 34, it assists in pulling the steel wire rope 31.

[0030] Working principle:

[0031] When setting up the stage lights, insert the square sleeve 5 onto the base 1 so that the rollers on the square sleeve 5 contact the round rod on the base 1. Then bolt the cross frame 6 and the square sleeve 5 together, and at the same time install the lights on the cross frame 6. Pass the iron chain through the pulley on the upright column 4, and then bolt the upright column 4 and the base 1 together. Connect the hook on the iron chain to the hanging ring on the square sleeve 5, and then manually lift the iron chain to raise the square sleeve 5 and the cross frame 6. Finally, bolt the square sleeve 5 and the upright column 4 together to complete the setup of the stage lights. When installing and fixing the cross frame 6 and the square sleeve 5, the worker lifts the cross frame 6 and aligns the installation holes on the cross frame 6 and the square sleeve 5, and then snaps the U-shaped plate 21 onto the cross frame 6. Insert the pin 22 into the U-shaped plate 21 and the positioning groove 23 to limit the U-shaped plate 21, so as to support the cross frame 6 and prevent the installation holes from being misaligned due to long-term manual support. Turn the screw rod 24, and by setting the auxiliary rod 25, limit the limiting plate 27 so that the limiting plate 27 is pushed into the limiting groove 26 to further limit the U-shaped plate 21. By setting the spring 28, limit the pin 22. When it is necessary to lift the square sleeve 5, start the pneumatic telescopic rod 32 (in this case, the air column is the pneumatic telescopic rod 32, and the telescopic force controls the lifting. The pneumatic telescopic rod is a product sold in the existing market, and how it specifically expands and contracts is not elaborated here as it is prior art), so that the steel wire rope 31 is pulled, thereby lifting the square sleeve 5 and avoiding manually lifting the square sleeve 5 by pulling the iron chain. By setting the pulley one 33, limit the steel wire rope 31, and by setting the pulley two 34, assist in pulling the steel wire rope 31.
