Description

Technical Field

[0001] This utility model relates to a modular stage, specifically a modular stage with casters that can be manually raised and lowered. Background Technology

[0002] For the construction of reviewing stands, temporary stages, etc., modular stages need to be used for assembly and combination, and the required number of modular stages should be selected according to the size required.

[0003] In existing technologies, some modular stages are not equipped with casters, requiring manual handling, which is time-consuming and labor-intensive. Others have casters directly installed at the bottom of the support columns, which may lead to accidental movement or casters falling off, causing the stage to become unstable and affecting safety. Utility Model Content

[0004] This utility model proposes a modular stage with hand-cranked lifting casters, aiming to overcome the above-mentioned shortcomings of the existing technology, realize quick lifting and lowering of casters, facilitate transportation and improve safety during use.

[0005] The technical solution of this utility model is a modular stage with hand-cranked lifting casters. Its structure includes a platform, columns, mounting frames, worm gear screw jacks, braked casters, and a handwheel. Columns are located at the four corners of the platform's bottom and the center of its long side. Each column has an adjustable support foot at its bottom. Connecting plates connect adjacent columns. Mounting frames are installed between opposite connecting plates near the two ends of the platform's length. A worm gear screw jack is installed near each end of each mounting frame. A braked caster is connected to the bottom lifting end of each worm gear screw jack. When the braked caster is in contact with the ground, the adjustable support foot is not in contact with the ground. Pushing the platform to the desired position, the worm gear screw jacks raise the braked caster off the ground, and the adjustable support foot contacts the ground, thus fixing the modular stage. Multiple modular stages can be assembled for use. Disassembly and relocation are performed by reversing the operation.

[0006] Preferably, a handwheel is installed at one end of the worm gear of each worm screw jack. By turning the handwheel, the corresponding worm screw jack is controlled to drive the braked caster to rise or fall.

[0007] Alternatively, preferably, the adjacent ends of the worms of two worm gear screw jacks on the same mounting frame are directly connected to a synchronous rotating rod, and a handwheel is installed on the worm of one of the worm gear screw jacks on the same mounting frame that is not connected to the synchronous rotating rod, with both handwheels located on the same side. By rotating the handwheel, the two worm gear screw jacks on the same mounting frame can be synchronously controlled to drive two braked casters to rise or fall synchronously.

[0008] The advantages of this utility model are: reasonable structural design, convenient for single-person operation, two sets of two manually controllable casters are set under the stage. When it is necessary to move the stage, the casters can be lowered to contact the ground, so that the support legs are off the ground and the stage can be moved. When the stage reaches the desired position, the casters can be manually controlled to rise off the ground, so that the support legs are in contact with the ground, achieving stable support and improving safety. Attached Figure Description

[0009] Figure 1 This is a structural schematic diagram of the modular stage with hand-cranked lifting and lowering casters of this utility model.

[0010] Figure 2 This is another structural diagram of the modular stage with hand-cranked lifting and lowering casters, which is part of this utility model.

[0011] In the diagram, 1 is the tabletop, 2 is the column, 3 is the adjustable support leg, 4 is the connecting plate, 5 is the mounting bracket, 6 is the worm gear screw jack, 7 is the caster with brake, 8 is the handwheel, and 9 is the synchronous rotating rod. Detailed Implementation

[0012] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.

[0013] like Figure 1 , 2 As shown, a modular stage with hand-cranked lifting casters includes a platform 1, columns 2, mounting frames 5, worm gear screw jacks 6, casters with brakes 7, and handwheels 8. Columns 2 are located at the four corners of the bottom of the platform 1 and at the center of its long side. Each column 2 has an adjustable support leg 2 at its bottom end. Connecting plates 4 connect adjacent columns 2. Mounting frames 5 are installed between two opposite connecting plates 4 near the two ends of the platform 1 along its length. A worm gear screw jack 6 is installed near each end of each mounting frame 5. A caster with brakes is connected to the bottom lifting end of each worm gear screw jack 6.

[0014] When in use, when the braked caster 7 is in contact with the ground, the adjustable support leg 2 is not in contact with the ground. Push the platform 1 to the desired position, and lift the braked caster 7 off the ground through each worm gear screw lift 6. The adjustable support leg 2 then contacts the ground, completing the fixation of the modular stage. Multiple modular stages can be used after being spliced ​​together. When disassembly and relocation are required after use, the reverse operation can be performed. Example 1

[0015] Each worm gear screw jack 6 has a handwheel 8 installed at one end of the worm.

[0016] By turning the handwheel 8, the corresponding worm gear screw jacks 6 are controlled to drive the braked casters 7 to rise or fall. Example 2

[0017] On the same mounting bracket 5, the adjacent ends of the worms of two worm gear screw jacks 6 are directly connected to the synchronous rotating rod 9. On the same mounting bracket 5, the worm of one of the worm gear screw jacks 6 that is not connected to the synchronous rotating rod 9 is equipped with a handwheel 8, and the two handwheels 8 are located on the same side.

[0018] By turning the handwheel 8, two worm gear screw jacks 6 on the same mounting bracket 5 can be simultaneously controlled to drive two casters 7 with brakes to rise or fall synchronously.

[0019] All of the components described above are existing technologies, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.

[0020] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present utility model, and these all fall within the protection scope of the present utility model.
