Description

Technical Field

[0001] This utility model belongs to the field of aluminum alloy frame technology, and specifically relates to a movable structure for an aluminum alloy frame stage. Background Technology

[0002] Aluminum alloy frame stages are a widely used stage structure in various performances, providing a solid guarantee for stage stability and safety with their unique structure and function. Aluminum alloy frame stages are mainly constructed from aluminum alloy rods cleverly connected, with common combinations including triangles and quadrilaterals, ensuring the overall structural stability. This structure can easily withstand the weight of various equipment and personnel movements on stage, ensuring the smooth running of the performance.

[0003] Existing aluminum alloy frame stages have significant drawbacks in terms of transportation. First, the overall structure of aluminum alloy frame stages is large and lacks its own mobility. When moving between sites, it is necessary to rely on external transportation equipment such as forklifts and trucks, which not only increases transportation costs, but also makes it difficult to achieve rapid transfer in some sites with limited space or lack of transportation equipment, reducing the flexibility and convenience of use. Second, traditional aluminum alloy frame stages cannot be fully retracted, resulting in a large size during transportation and occupying too much transportation space.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is a movable structure for an aluminum alloy frame stage, including a base. Two positioning seats are installed on the upper end of the base, and a frame structure is rotatably installed on both sides of the two positioning seats. Multiple support legs are installed on the bottom surface of the frame structure. An adjustment component and a movable component are installed in the inner cavity of the base. A support component is installed on the adjustment component. The bottom of the support component is initially lower than the bottom of the movable component. A linkage structure is installed between the support component and the movable component. The adjustment component is used to drive the support component to move upward. At the same time as the support component moves upward, the linkage structure can follow the movement of the support component to drive the movable component to move downward, so that the bottom of the movable component is higher than the bottom of the support component, thereby changing the base from a supporting form to a movable form.

[0006] The adjusting assembly includes a screw, the lower end of which is rotatably mounted on the bottom wall of the inner cavity of the base, and a worm gear mounted on the upper end of the screw. The adjusting assembly also includes a rotating rod, which is rotatably mounted on the side wall of the inner cavity of the base. A worm gear is mounted on the rotating rod, and the worm gear meshes with the worm gear. A handle is mounted on one end of the rotating rod.

[0007] The support includes a support plate, which is threaded onto the screw rod. Support feet are evenly arranged on the bottom surface of the support plate, and the lower ends of the support feet extend outward through the bottom surface of the base.

[0008] There are two sets of movable parts. The movable parts include a movable plate. Connecting rods are installed at both ends of the bottom surface of the movable plate. The lower ends of the connecting rods all extend through the bottom surface of the base and are equipped with casters.

[0009] There are two sets of linkage structures. Each set of linkage structures includes two first racks, two second racks, and two mounting rods. The first racks are all mounted on one side of the support plate, the second racks are all mounted on one side of the moving plate, and the mounting rods are all mounted on the inner wall of the base. Each mounting rod is rotatably mounted with a gear. Each first rack and each second rack corresponds to and meshes with a gear.

[0010] The frame structure includes a first frame and a second frame. One end of the first frame is rotatably mounted on a positioning seat. Two fixed seats are rotatably provided at the ends of the first frame and the second frame that are close to each other. The end of the second frame that is close to the first frame is rotatably mounted on a fixed seat.

[0011] Both the first frame and the second frame have mounting slots on their bottom surfaces. The number of mounting slots is the same as the number of support legs. One end of each support leg is rotatably mounted in a mounting slot. Each support leg is equipped with a fastener.

[0012] This utility model has the following beneficial effects:

[0013] When in operation, the support feet are in contact with the ground, working in conjunction with the support legs to stably support the first and second frames, ensuring stability. When movement is required, the support legs can be retracted by unlocking the fasteners, folding the first and second frames, significantly reducing the area occupied by the frame structure, facilitating transportation and storage. Subsequently, the throttle is used to drive the rotating rod, worm gear, worm wheel, and screw to rotate, causing the support plate to rise and lift the support feet off the ground. Simultaneously, through gear and rack transmission, the casters move down until they contact the ground, allowing the device to quickly transform from a stable support form to a flexible movement form. Workers only need a small pushing force to move the device, effectively solving the problem of inconvenient movement of large stage frames, balancing stability and portability, and significantly improving efficiency and adaptability to different scenarios.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-6 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0023] Please see Figures 1-3 As shown:

[0024] This embodiment provides a movable structure for an aluminum alloy frame stage, including a base 1. Two positioning seats 2 are installed on the upper end of the base 1. A frame structure 3 is rotatably installed on both sides of the two positioning seats 2. Multiple support legs 4 are installed on the bottom surface of the frame structure 3. An adjustment component 5 and a movable component 6 are installed in the inner cavity of the base 1. A support component 7 is installed on the adjustment component 5. The bottom of the support component 7 is initially lower than the bottom of the movable component 6. A linkage structure 8 is installed between the support component 7 and the movable component 6. The adjustment component 5 is used to drive the support component 7 to move upward. At the same time as the support component 7 moves upward, the linkage structure 8 can follow the movement of the support component 7 to drive the movable component 6 to move downward, so that the bottom of the movable component 6 is higher than the bottom of the support component 7, thereby changing the base 1 from a supporting form to a movable form.

[0025] In use, the frame structure 3 unfolds horizontally, parallel to the ground. The bottom of the support member 7 is lower than the bottom of the moving member 6, and the support member 7 is in contact with the ground, providing support. Multiple support legs 4 on the bottom of the frame structure 3 ensure stability during use. When no longer in use and needing to be moved, the frame structure 3 is first reduced in size, and then the end connecting the frame structure 3 to the positioning seat 2 is rotated, changing the frame structure 3 from a horizontally parallel state to a horizontally perpendicular state, and stored above the base 1, thus reducing the overall size of the frame structure 3. Then, the adjustment component 5 is operated, causing the support member 7 to move upwards. Because a linkage structure 8 is installed between the support member 7 and the moving member 6, as the support member 7 moves upwards, the linkage structure 8 simultaneously causes the moving member 6 to move downwards, making the bottom of the support member 7 higher than the moving member 6. The support member 7 detaches from the ground, and the moving member 6 comes into contact with the ground, allowing the operator to easily push the device away for flexible operation without relying on external transportation equipment.

[0026] like Figure 3 , Figure 4 As shown, the adjusting assembly 5 includes a screw 9, the lower end of which is rotatably mounted on the bottom wall of the inner cavity of the base 1, and a worm gear 10 is mounted on the upper end of the screw 9. The adjusting assembly 5 also includes a rotating rod 11, which is rotatably mounted on the side wall of the inner cavity of the base 1. A worm gear 12 is mounted on the rotating rod 11, and the worm gear 12 meshes with the worm gear 10. A handle 13 is mounted on one end of the rotating rod 11, so that the operator can rotate the rotating rod 11 and the worm gear 12 by rotating the handle 13. Since the worm gear 12 meshes with the worm gear 10, according to the transmission principle of the worm gear 10 and worm gear 12, the rotation of the worm gear 12 will drive the worm gear 10 to rotate, and then the worm gear 10 will drive the screw 9 to rotate, so that the screw 9 drives the support 7 to move up and down.

[0027] like Figure 3 , Figure 4As shown, the support component 7 includes a support plate 14, which is threaded onto the screw 9. Support feet 15 are evenly arranged on the bottom surface of the support plate 14, with their lower ends extending beyond the bottom surface of the base 1. The support feet 15 will contact the ground during use to provide support. The movable component 6 consists of two sets, each including a movable plate 16. Connecting rods 17 are installed at both ends of the bottom surface of the movable plate 16, with their lower ends extending beyond the bottom surface of the base 1. Casters 18 are installed at the lower ends of the connecting rods 17. When the device needs to be moved, it is operated via the screw... The rotation of 9 causes the support plate 14 to move upward, and the support foot 15 will follow. Through the linkage structure 8, as the support plate 14 continues to move upward, the linkage structure 8 can drive the moving plate 16 to move downward continuously. The connecting rod 17 drives the caster wheel 18 to follow the moving plate 16 to move downward continuously, gradually approaching and finally contacting the ground. Meanwhile, the support foot 15 gradually leaves the ground as the support plate 14 moves upward, so that the bottom of the caster wheel 18 is higher than the bottom of the support foot 15. At this time, the operator only needs to apply a small pushing force to move the device through the caster wheel 18, so that the device can be operated flexibly.

[0028] like Figure 3-5 As shown, there are two sets of linkage structures 8. Each set of linkage structures 8 includes two first racks 19, two second racks 20, and two mounting rods 27. The first racks 19 are all mounted on one side of the support plate 14, the second racks 20 are all mounted on one side of the movable plate 16, and the mounting rods 27 are all mounted on the inner wall of the base 1. Each mounting rod 27 is rotatably mounted with a gear 21. Each first rack 19 and each second rack 20 corresponds to and meshes with a gear 21. When the screw 9 drives the support plate 14 to move upward, the first racks 19 will also follow the support plate 14. As the first rack 19 and the second rack 20 both mesh with the gear 21, the first rack 19 moves upward, causing the gear 21 to rotate. This causes the second rack 20 mounted on the moving plate 16 to move downward, so that the moving plate 16 follows the second rack 20 downward. This causes the universal wheel 18 at the lower end of the connecting rod 17 to move downward, gradually approaching and finally contacting the ground. Meanwhile, the support foot 15 gradually leaves the ground as it moves upward, so that the bottom of the universal wheel 18 is higher than the bottom of the support foot 15, thus achieving autonomous movement and transfer.

[0029] like Figure 1 , Figure 2As shown, the frame structure 3 includes a first frame 22 and a second frame 23. One end of the first frame 22 is rotatably mounted on the positioning seat 2. Two fixed seats 24 are rotatably arranged at the ends of the first frame 22 and the second frame 23. The end of the second frame 23 is rotatably mounted on the fixed seat 24 at the end of the first frame 22. In use, both the first frame 22 and the second frame 23 are horizontally parallel to the ground. A stable frame plane is formed by the support legs 4 to ensure stability during use. When the device needs to be moved and transported, the end of the first frame 22 connected to the positioning seat 2 is rotated so that the first frame 22 changes from a horizontally parallel state to a horizontally perpendicular state to the base 1, so that the two first frames 22 are folded onto the base 1. After this step is completed, the end of the second frame 23 connected to the fixed seat 24 is rotated so that the second frame 23 overlaps with the first frame 22, realizing efficient folding and storage of the frame structure 3 and further reducing the area occupied by the frame structure 3 during operation.

[0030] like Figure 2 As shown, both the first frame 22 and the second frame 23 have mounting slots 25 on their bottom surfaces. The number of mounting slots 25 is the same as the number of support legs 4. One end of each support leg 4 is rotatably mounted in a mounting slot 25. Each support leg 4 is equipped with a fixing element 26, which includes, but is not limited to, bolts, pins, and buckles. The fixing element 26 is used to fix the support leg 4 in a perpendicular state to the ground. In use, the support leg 4 is rotated out of the mounting slot 25 to make it perpendicular to the ground, and then the fixing element 26 is used to fix the support leg 4 to ensure that the support leg 4 is stably supported. When folding and transportation are required, the fixing effect of the fixing element 26 is released, and the support leg 4 is rotated back into the mounting slots 25 on the bottom surfaces of the first frame 22 and the second frame 23, thereby avoiding the support leg 4 from affecting the folding and storage of the first frame 22 and the second frame 23.

[0031] The working principle of the aluminum alloy frame stage movable structure provided by this utility model is as follows: Both the first frame 22 and the second frame 23 are horizontally parallel to the ground. At this time, the bottom of the support leg 15 is higher than the caster wheel 18, so that the support leg 15 contacts the ground, thereby ensuring the stability of the first frame 22 and the second frame 23 through the support leg 4 and the support leg 15. When the device needs to be operated, the locking function of the unlocking fastener 26 can be first used to retract the support leg 4 into the mounting slot 25. Then, rotate the end of the first frame 22 connected to the positioning seat 2, so that the first frame 22 changes from a horizontally parallel state to a horizontally perpendicular state to the base 1, causing the two first frames 22 to be folded onto the base 1. Then, rotate the end of the second frame 23 connected to the fixing seat 24, so that the second frame 23 overlaps with the first frame 22, achieving high efficiency of the frame structure 3. Folding and storage further reduces the area occupied by the frame structure 3 during operation. After the storage step is completed, the throttle 13 drives the rotating rod 11 and worm gear 12 to rotate, thereby driving the worm wheel 10 meshing with it to rotate. This causes the screw 9 to rotate with the worm wheel 10, which in turn drives the support plate 14 to move upward. At the same time, it drives the support foot 15 and the first rack 19 to move upward. As the first rack 19 continues to move, it drives the gear 21 to rotate, causing the second rack 20 meshing with it to move downward. This drives the moving plate 16, connecting rod 17 and caster wheel 18 to move downward, gradually approaching and finally contacting the ground. Meanwhile, the support foot 15 gradually leaves the ground as the support plate 14 moves upward, so that the bottom of the caster wheel 18 is higher than the bottom of the support foot 15. At this time, the operator only needs to apply a small pushing force to move the device through the caster wheel 18, thus achieving flexible operation of the device.

[0032] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
