Description

Technical Field

[0001] The utility model relates to the field of stage equipment, in particular to a stage which is convenient for assembly and disassembly. Background Art

[0002] As people's living standards improve, temporary stages are often built when holding events or celebrations. The temporary stages can be quickly assembled and disassembled. They are usually composed of several modular components, including stage panels, support legs, connectors, etc., which can be easily assembled and disassembled for easy transportation and storage.

[0003] In the prior art, the connecting parts used to connect the support legs to the stage board mainly use bolt assemblies. There are two main types of bolt assembly structures. One is that there is a connecting flange plate on the top of the support leg, and the connecting flange plate is fixed to the lower surface of the stage board by multiple bolts to achieve the installation of the support leg; the other is that a slot is set on the lower surface of the stage board, the upper end of the support leg is inserted into the slot, and then the bolt is screwed into the slot from the outside to the inside from the side wall of the slot, so that the end of the bolt is pressed against the side wall of the upper end of the support leg inserted into the slot to achieve the fixation of the support leg. When these two types of bolt assemblies are used for disassembly and assembly, the first one requires the use of tools to tighten multiple bolts, which is inconvenient to operate. Secondly, the screwed bolts also need to be stored. If the storage is not good, it is easy to cause the bolts to be lost; the second one is that when the support leg is in the positioning state, the support leg is only tightened by one bolt, which has the problem of relatively poor stability. Therefore, in the prior art, the connection structure between the support leg and the stage board needs to be further improved. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a stage that is easy to assemble and disassemble, which can significantly improve the convenience of setting up and dismantling a temporary stage.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] The driving handle has a pull head with an eccentric structure, and the pull head is hinged on one end of the pull rod. After the driving handle is rotated, a locking position and a loosening position are formed relative to the clamp. In the locking position, the edge of the pull head with the eccentric structure away from the hinge point corresponds to the connecting ear, pulling the two connecting ears together. In the loosening position, the edge close to the hinge point corresponds to the connecting ear, so that the two connecting ears are naturally separated.

[0009] The elastic pad is arranged between the pull head and the connecting ear.

[0029] Combination Figures 1 to 5 The utility model is further described with respect to the stage which is convenient for disassembly and assembly.

[0030] A stage that is easy to assemble and disassemble includes a stage board 1 and support legs 2 arranged at the four corners of the stage board 1. The feature is that it also includes four groups of connection components 3 connecting the four support legs 2 to the lower surface of the stage board 1, and each group of connection components 3 includes a clamp 31, a driving handle 36 and an elastic pad 35.

[0031] The clamp 31 is fixed to the lower surface of the stage panel 1 by welding. The clamp 31 is an open annular structure, and has two connecting ears 311 extending outward at the opening position. Each connecting ear 311 has a through hole, and a pull rod 32 passing through the two through holes is arranged between the two connecting ears 311.

[0032] The driving handle 36 has a gripping portion 363 and a pull head 362 of an eccentric structure. The pull head 362 has an eccentric hole and is eccentrically hinged to one end of the pull rod 32 through a pin. After the driving handle 36 is rotated, the pull head 362 forms a locking position and a loosening position relative to the clamp 31. In the locking position, the edge 3621 of the pull head 362 of the eccentric structure that is away from the hinge point, i.e., the pin, corresponds to and fits the connecting ear 311, pulling the two connecting ears 311 together to make the clamp 31 hold tightly; in the loosening position, the edge 3622 close to the hinge point corresponds to the connecting ear 311, so that the two connecting ears 311 are naturally separated under the action of their own elastic force, so that the clamp 31 is opened.

[0033] The elastic pad 35 is disposed between the pull head 362 and the connecting ear 311 to provide elastic buffer support between the connecting ear 311 and the pull head 362 .

[0034] In the pull rod 32 structure, the pull rod 32 is a screw rod, and one end of the pull rod 32 is connected with a nut 34 that can be abutted against the connecting ear 311 to prevent the pull rod 32 from falling out in the direction of the other connecting ear 311; secondly, the position of the nut 34 on the screw rod can be adjusted through the threaded fit between the screw rod and the nut 34, thereby adjusting the tension generated by the pull head 362 on the two connecting ears 311 when in the locking position. A hinge hole is provided at the other end of the pull rod 32 for the pull head 362 to be hinged, i.e., for the pin to pass through.

[0035] The pull rod 32 is sleeved with a spring 33 , and the spring 33 is located between the two connecting ears 311 . When the pull head 362 is in the loosened position, the spring 33 can assist the clamp 31 to open, thereby improving stability.

[0036] In the structure of the driving handle 36 , the pull head 362 has a reinforcing rib 361 extending along the hinge point, that is, the eccentric hole. The reinforcing rib 361 can significantly improve the structural strength of the pull head 362 so that the clamp 31 can be effectively clamped.

[0037] The gripping portion 363 of the driving handle 36 is sleeved with a rubber sleeve 364 , which can significantly improve the gripping comfort of the user.

[0038] In the structure of the elastic pad 35, the elastic pad 35 includes a bottom plate 351 and a bending plate 352. The bottom plate 351 has a through hole for the pull rod 32 to pass through; the bending plate 352 is integrally formed on the side of the bottom plate 351, and is bent 15 to 60 degrees toward the back, and an elastic space is formed on the back of the elastic pad 35; the back of the elastic pad 35 is supported on the connecting ear 311, and the front is pressed by the pull head 362. The elastic pad 35 can provide elastic buffer support, which can significantly improve the stability of the clamping of the support leg 2 by the clamp 31 and improve the safety of use. That is, when the support leg 2 is hit, the support leg 2 will squeeze the clamp 31 to open slightly, and the two connecting ears 311 of the clamp 31 squeeze the bending part in the elastic pad 35 to deform adaptively, thereby releasing the impact force on the support leg 2. After the release, the elastic pad 35 is reset, so that the clamp 31 locks the support leg 2 again. Otherwise, without the elastic pad 35, when the supporting leg 2 is hit, the connection structure between the connecting ear 311, the pull rod 32 and the pull head 362 is easily damaged, causing the supporting leg 2 to immediately lose its fixing effect, thereby causing the stage to collapse.

[0039] Laterally extending limiting walls 354 are provided at the upper and lower positions of the bottom plate 351. The two limiting walls 354 are respectively located on the upper and lower sides of the slider 362 to prevent the elastic pad 35 from rotating. The two opposite sides of the bottom plate 351 and the bending plate 352 can be stably pressed against the connecting ear 311 to achieve an elastic buffering effect.

[0040] A reinforcing rib 353 is formed between the bottom plate 351 and the bending plate 352 , and the reinforcing rib 353 can significantly improve the overall structural strength of the elastic pad 35 .

[0041] During actual use, the user holds the gripping portion 363 of the driving handle 36 and rotates the driving handle 36 90° to tighten or loosen the clamp 31, thereby clamping or removing the supporting leg 2 from the clamp 31, which is easy to operate. When the supporting leg 2 is in a fixed state, the inner wall of the clamp 31 can be completely fitted with the outer wall of the supporting leg 2, which significantly improves the stability of the supporting leg 2 fixed in the clamp. The elastic pad 35 can play a role of elastic support and buffering, further improving the stability of the supporting leg 2 fixed in the clamp 31.
