[0001] The utility model relates to the technical field of stage performance equipment, in particular to a performance wave board that can prevent falling to the ground. Background Art

[0002] Stage performance equipment refers to various equipment fixed on the stage for theatrical performances, with scenery equipment being the most common, in addition to lighting equipment, sound effect equipment, stunt equipment, etc. In theaters that perform repertoires, there are sometimes special equipment used specifically for a certain repertoire, and performance surfboards are also one of the stage performance equipment.

[0003] Before the existing performance wave board is used on the stage, it is necessary to connect the equipment to the prefabricated board of the stage to increase the stress surface of the equipment. The installation method using bolts requires the bolts to be removed and then lifted when the equipment is transported, which leads to complicated transportation and installation problems.

[0004] For this reason, a kind of performance wave board that avoids falling to the ground is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a performance wave board that can prevent falling from the ground, so as to solve the problem that the installation method proposed in the above background technology by means of bolts requires the bolts to be removed when the equipment is transported, and then the equipment is lifted, thus resulting in complicated transportation and installation.

[0013] Preferably, there are multiple groups of fixing ropes arranged in a fan shape, and the support frame is arranged in an inverted "V" shape.

[0014] Advantages of the present utility model:

[0015] 1. By sliding the telescopic rod inside the extension plate, the present utility model lengthens the force-bearing length between the equipment and the ground. Then, by placing the counterweight on the top of the telescopic rod, the telescopic rod can be fixed. Moreover, the telescopic rod lengthens the force arm, which can reduce the use of counterweights and is more convenient during installation, thereby increasing the stability during fixation, solving the problem of low efficiency in installation and handling in the past when using bolt fixation, and improving the convenience during handling and fixation.

[0016] 2. By pressing the pressing plate, the pressing wheel rotates outside the eccentric shaft, so that the pressing wheel pushes the pressing block to squeeze inside the pressing block, fixing the telescopic rod inside the extension plate, thereby selecting different lengths of the telescopic rod for fixation, solving the problem that the telescopic rod cannot be fixed at any structure when using a common telescopic structure, and increasing the effect that the pressing groove can be fixed at different lengths.

Detailed implementation manners

[0024] In order to make the purpose, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in combination with specific embodiments.

[0026] Such as Figures 1 to 5As shown in the figure, a specific embodiment of the present utility model provides a wave board for performing without a ground anchor, which includes a load-bearing block 2. A support frame 14 is fixedly connected to the top of the load-bearing block 2. Installation beams 18 are fixedly connected to opposite sides of the support frame 14. A fixing rope 17 is fixedly connected to the bottom of the installation beam 18. A wave board main body 16 is fixedly connected to the bottom of the fixing rope 17. An extension board 3 is fixedly connected to one side of the load-bearing block 2. A telescopic rod 4 is slidably connected inside the extension board 3. A pressing groove 5 is opened at the top of the telescopic rod 4. A counterweight block 13 is embedded at the top of the pressing groove 5. A pressing block 6 abuts against the pressing groove 5 near the extension board 3. A pressing assembly is arranged at the top of the pressing block 6. The pressing assembly is used to cooperate with the pressing block 6 to fix the telescopic rod 4. The pressing assembly includes a pressing wheel 7. An eccentric shaft 10 is rotatably connected to the inner side of the pressing wheel 7 near the top. An installation frame 9 is fixedly connected to the outside of the eccentric shaft 10.

[0027] By adopting the above technical solution, the present utility model rotates the pressing wheel 7 to make the pressing wheel 7 rotate around the eccentric shaft 10. First, separate the pressing wheel 7 from the top of the pressing block 6, so that the telescopic rod 4 can be pulled out. After selecting a suitable length, rotate the pressing wheel 7 again to make the pressing wheel 7 press on the surface of the pressing block 6, so that the pressing wheel 7 pushes the pressing block 6 and presses it into the pressing groove 5 opened in the telescopic rod 4, thereby fixing the selected length of the pressing groove 5. When the telescopic rod 4 is fixed inside, the counterweight block 13 can be placed on the surface of the telescopic rod 4, and the bottom of the counterweight block 13 is embedded inside the pressing groove 5, so as to achieve the effect of counterweight fixation. In this way, through the support of the support frame 14, the wave board main body 16 suspended can perform by cooperating with the installation beam 18 and the fixing rope 17.

[0028] Specifically, as Figure 4 and Figure 5 shown, the bottom of the pressing wheel 7 abuts against the top of the pressing block 6. A rotating groove 19 is opened at the top of the extension board 3. The pressing wheel 7 rotates inside the rotating groove 19. A sliding groove 20 is opened at the top of the extension board 3 near the rotating groove 19. A sliding rod 8 is slidably connected inside the sliding groove 20. The sliding rod 8 is fixedly connected to the top of the pressing block 6. The installation frame 9 is fixedly connected to the outside of the extension board 3. A pressing plate 11 is fixedly connected to the outside of the pressing wheel 7. A support block 12 is fixedly connected to one end of the telescopic rod 4 away from the extension board 3.

[0029] By adopting the above technical solution, the pressing plate 11 can be used to control the downward pressing wheel 7 to rotate externally along the eccentric shaft 10, and the downward pressing wheel 7 is rotated along the rotation groove 19, so that the downward pressing wheel 7 presses against the top of the downward pressing block 6, and in this way, the downward pressing block 6 can fix the telescopic rod 4. When the downward pressing wheel 7 disengages from the top of the downward pressing block 6 and the telescopic rod 4 is pulled to adjust the length, the sliding rod 8 slides inside the rotation groove 19, which can ensure that the downward pressing block 6 will not be pulled out as the telescopic rod 4 is pulled. After being pulled out and fixed, the support block 12 can also cooperate with the telescopic rod 4 to support the counterweight block 13, ensuring that the heights of the support block 12 and the load-bearing block 2 are the same, so as to ensure the stability after the counterweight block is installed and prevent it from shaking. The connecting plate 1 connects the load-bearing block 2, and the support assembly can be fixed.

[0030] Specifically, as Figure 1 and Figure 2 shown, a connecting plate 1 is fixedly connected to one side of the load-bearing block 2 away from the extension plate 3. A support assembly is arranged on the top of the load-bearing block 2 and is used for support during performances. The support assembly includes a support frame 14, the support frame 14 is arranged in a triangular shape, a lengthening frame 15 is fixedly connected to one side of the support frame 14 close to the extension plate 3, and one end of the lengthening frame 15 away from the support frame 14 is fixedly connected to the top of the extension plate 3. There are multiple groups of fixing ropes 17 arranged in a fan shape, and the support frame 14 is arranged in an inverted "V" shape.

[0031] By adopting the above technical solution, the fixing ropes 17 that fix the installation beam 18 and the corrugated board main body 16 are supported by the support frame 14. During fixation, the force received by the support frame 14 is dispersed by the lengthening frame 15 and then given to the extension plate 3. In this way, the lengthening effect of the telescopic rod 4 can be utilized to increase the stability of the fixed support, and this also avoids the complexity during disassembly and handling after bolt fixation, improving the stability during fixation and the convenience during handling.
