Description

Technical Field

[0001] This utility model relates to the field of sports venue facilities technology, and in particular to a movable sports venue grandstand module. Background Technology

[0002] During sports competitions, it is sometimes necessary to set up temporary stands to facilitate the viewing of sports events by athletes, coaches, or spectators. Existing stands need to be transported as a whole or different parts from various locations need to be transported to the site for assembly. When using the above methods, not only is the transportation difficult, but the on-site assembly is also time-consuming and labor-intensive, consuming a lot of manpower and resources. Utility Model Content

[0003] The purpose of this utility model is to provide a mobile sports stadium grandstand module, which solves the problem that due to the large size of the grandstand, the mobile version requires overall transportation or has too many parts, resulting in cumbersome overall device transportation or assembly.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A movable sports stadium grandstand module includes a grandstand body. A storage cavity is provided on the left side of the grandstand body. A sliding groove is provided in the middle of the top of the storage cavity. A slider is slidably installed in the inner cavity of the sliding groove. A threaded hole is provided in the middle of the slider. A circular hole is provided on the right side of the inner cavity of the sliding groove. Limiting holes are provided on both the front and rear sides of the right side of the circular hole. An installation hole is provided on the right side of the grandstand body. A threaded rod is movably installed in the inner cavity of the circular hole. A cylindrical cavity is provided in the middle of the threaded rod. Locking holes are provided on both the front and rear sides of the right side of the cylindrical cavity. A through hole is provided in the middle of the right side of the threaded rod. A return spring is rotatably connected to the left side of the inner cavity of the cylindrical cavity. A left circular block is fixedly connected to the right side of the return spring. Locking blocks are fixedly installed on both the front and rear sides of the right side of the left circular block. A circular rod is fixedly installed in the middle of the right side of the left circular block. A right circular block is fixedly installed on the part of the circular rod extending out of the right side of the through hole. Limiting blocks are fixedly installed on both the front and rear sides of the outer surface of the right circular block. A circular plate is fixedly installed on the right side of the right circular block.

[0005] Preferably, a grandstand extension is fixedly installed at the bottom of the slider, and base columns are fixedly installed at the four corners of the bottom of the grandstand extension and the grandstand body. Adjustment holes are provided at the four corners of the bottom of the grandstand extension and the grandstand body. Adjustment rods are detachably installed in the inner cavity of the adjustment holes. Spring dampers are fixedly installed at the bottom of the adjustment rods, and base blocks are fixedly installed at the bottom of the spring dampers.

[0006] Preferably, the left and right sides of the inner cavity of the slide groove both penetrate the left and right sides of the main body of the grandstand. The left side of the circular hole does not penetrate the left side of the main body of the grandstand. The right side of the circular hole is connected to the left side of the mounting hole. The cross-sectional diameter of the outer surface of the threaded rod matches the diameter of the cross-section of the threaded hole and the inner cavity of the circular hole. The inner wall of the threaded hole is provided with a thread that matches the shape of the outer surface of the threaded rod. Thus, when in use, the threaded rod passes through the mounting hole and extends into the circular hole and the threaded hole, and is movably mounted on the left side of the inner cavity of the slide groove. When the threaded rod rotates, it drives the slider to move left and right in the inner cavity of the slide groove through the threaded hole.

[0007] Preferably, the cylindrical cavity does not penetrate the left and right sides of the threaded rod. The right side of the cylindrical cavity is connected to the through hole through a locking hole. The cross-sectional diameter of the inner cavity of the cylindrical cavity matches the cross-sectional diameter of the inner cavity of the locking hole. The cross-sectional diameter of the inner cavity of the cylindrical cavity is larger than the cross-sectional diameter of the inner cavity of the through hole. The cross-sectional diameter of the outer surface of the round rod matches the cross-sectional diameter of the inner cavity of the through hole. The cross-sectional shape of the outer surface of the left round block matches the cross-sectional shape of the inner cavity of the cylindrical cavity. The shape of the outer surface of the locking block matches the shape of the inner cavity of the locking hole. The cross-sectional shape of the outer surface of the round rod matches the cross-sectional shape of the inner cavity of the through hole. Thus, in use, by matching the outer surface shapes of the left round block, locking block, and round rod with the shapes of the inner cavities of the cylindrical cavity, locking hole, and through hole, the left side of the round rod cannot be moved out because the left round block can only slide left and right in the inner cavity of the cylindrical cavity. At the same time, when the locking block rotates and moves into the inner cavity of the locking hole, the round rod drives the threaded rod to rotate through the locking block and locking hole.

[0008] Preferably, the cross-sectional shape of the outer surface of the right circular block matches the cross-sectional shape of the outer surface of the threaded rod, the outer surface shape of the limiting block matches the inner cavity shape of the limiting hole, the outer surface shape of the circular plate matches the inner cavity shape of the mounting hole, and a groove is provided on the right side of the circular plate. In use, the operator can use the groove to move the circular rod left and right through the circular plate and the right circular block. When not in use, the operator can rotate the circular plate in the inner cavity of the mounting hole through the groove until the position of the limiting block corresponds to the position of the limiting hole. At this time, the limiting block extends into the inner cavity of the limiting hole to fix the circular plate.

[0009] Preferably, the adjustment hole is located in the middle of the inner cavity of each base column frame, and the inner wall of the adjustment hole is provided with a thread that matches the shape of the outer surface of the adjustment rod. The height of the adjustment rod and the height of the inner cavity of the adjustment hole are both greater than the height of the base column frame. Therefore, in use, by using the detachable adjustment rod and its bottom structure, when the placement position of the grandstand body and grandstand extension is uneven, the height of the grandstand body and grandstand extension can be adjusted to a horizontal position by installing the adjustment rod and controlling the height of the adjustment rod after installation. This, combined with the spring damping device, improves the stability of the grandstand body and grandstand extension during use.

[0010] Compared with the prior art, the advantages of this utility model are as follows:

[0011] This utility model utilizes a combination of a locking block structure and a round rod structure. During operation, after all the structures are correctly assembled, the round plate is stretched to the right through the pull groove and continuously rotated until the left round block moves to the right side of the cylindrical cavity and the locking block extends into the locking hole cavity. At this point, rotating the round plate can drive the threaded rod to rotate through the round rod, thereby adjusting the position of the slider on the surface of the threaded rod. This controls the extension body of the grandstand to move out of or into the storage cavity opened on the left side of the grandstand body, achieving the effect of facilitating the rapid retraction of the stadium grandstand for convenient subsequent transportation or simple and quick assembly, thus improving the overall work efficiency.

[0012] This utility model utilizes the combined use of an adjustment hole structure and an adjustment rod structure. During operation, the adjustable rod and its bottom structure are detachably installed. When the placement of the grandstand body and grandstand extension is uneven, the height of the adjustable rod after installation can be controlled to adjust the grandstand body and grandstand extension to a horizontal position. In conjunction with the spring shock absorber, the stability of the grandstand body and grandstand extension during use is improved. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1 to 8 This embodiment provides a movable sports stadium grandstand module, including a grandstand body 1. A storage cavity 2 is provided on the left side of the grandstand body 1. A sliding groove 3 is provided in the middle of the top of the inner cavity of the storage cavity 2. A slider 4 is slidably installed in the inner cavity of the sliding groove 3. A threaded hole 5 is provided in the middle of the slider 4. A round hole 6 is provided on the right side of the inner cavity of the sliding groove 3. Limiting holes 7 are provided on both the front and rear sides of the right side of the round hole 6. An installation hole 8 is provided on the right side of the grandstand body 1. A threaded rod 9 is movably installed in the inner cavity of the round hole 6.

[0024] The left and right sides of the inner cavity of the slide groove 3 are both through the left and right sides of the main body 1 of the grandstand. The left side of the round hole 6 does not penetrate the left side of the main body 1 of the grandstand. The right side of the round hole 6 is connected to the left side of the mounting hole 8. The cross-sectional diameter of the outer surface of the threaded rod 9 matches the diameter of the cross-section of the inner cavity of the threaded hole 5 and the round hole 6. The inner wall of the threaded hole 5 is provided with a thread that matches the shape of the outer surface of the threaded rod 9. Thus, when in use, the threaded rod 9 passes through the mounting hole 8 and extends into the round hole 6 and the threaded hole 5 and is movably mounted on the left side of the inner cavity of the slide groove 3. When the threaded rod 9 rotates, it drives the slider 4 to move left and right in the inner cavity of the slide groove 3 through the threaded hole 5.

[0025] A cylindrical cavity 10 is provided in the middle of the threaded rod 9. A locking hole 11 is provided on both the front and rear sides of the right side of the cylindrical cavity 10. A through hole 12 is provided in the middle of the right side of the threaded rod 9. A return spring 13 is rotatably connected to the left side of the cylindrical cavity 10. A left round block 14 is fixedly connected to the right side of the return spring 13. Locking blocks 15 are fixedly installed on the front and rear sides of the right side of the left round block 14.

[0026] The cylindrical cavity 10 does not penetrate the left and right sides of the threaded rod 9. The right side of the cylindrical cavity 10 is connected to the through hole 12 through the locking hole 11. The cross-sectional diameter of the inner cavity of the cylindrical cavity 10 matches the cross-sectional diameter of the inner cavity of the front and rear locking holes 11. The cross-sectional diameter of the inner cavity of the cylindrical cavity 10 is larger than the cross-sectional diameter of the inner cavity of the through hole 12. The cross-sectional shape of the outer surface of the round rod 16 matches the cross-sectional diameter of the inner cavity of the through hole 12. The cross-sectional shape of the outer surface of the left round block 14 matches the cross-sectional shape of the inner cavity of the cylindrical cavity 10. The outer surface shape of the locking block 15 matches the locking hole 11. The inner cavity shapes are matched, and the cross-sectional shape of the outer surface of the round rod 16 matches the cross-sectional shape of the inner cavity of the through hole 12. Thus, when in use, by matching the outer surface shapes of the left round block 14, the locking block 15, the round rod 16, the cylindrical cavity 10, the locking hole 11, and the inner cavity shapes of the through hole 12, the left side of the round rod 16 cannot be moved out because the left round block 14 can only slide left and right in the inner cavity of the cylindrical cavity 10. At the same time, when the locking block 15 rotates and moves into the inner cavity of the locking hole 11, the round rod 16 drives the threaded rod 9 to rotate through the locking block 15 and the locking hole 11.

[0027] A round rod 16 is fixedly installed on the middle right side of the left round block 14. A right round block 17 is fixedly installed on the part of the round rod 16 that extends out of the right side of the through hole 12. Limiting blocks 18 are fixedly installed on both the front and rear sides of the outer surface of the right round block 17. A round plate 19 is fixedly installed on the right side of the right round block 17.

[0028] The cross-sectional shape of the outer surface of the right circular block 17 matches the cross-sectional shape of the outer surface of the threaded rod 9, the outer surface shape of the limiting block 18 matches the inner cavity shape of the limiting hole 7, and the outer surface shape of the circular plate 19 matches the inner cavity shape of the mounting hole 8. A groove is provided on the right side of the circular plate 19. When in use, the operator can use the groove to drive the circular rod 16 to move left and right through the circular plate 19 and the right circular block 17. When not in use, the operator can rotate the circular plate 19 in the inner cavity of the mounting hole 8 through the groove until the position of the limiting block 18 corresponds to the position of the limiting hole 7. At this time, the limiting block 18 extends into the inner cavity of the limiting hole 7 to fix the circular plate 19.

[0029] A grandstand extension 20 is fixedly installed at the bottom of the slider 4. Base column frames 21 are fixedly installed at the four corners of the bottom of the grandstand extension 20 and the grandstand body 1. Adjustment holes 22 are opened at the four corners of the bottom of the grandstand extension 20 and the grandstand body 1. An adjustment rod 23 is detachably installed in the inner cavity of the adjustment hole 22. A spring damper 24 is fixedly installed at the bottom of the adjustment rod 23. A base block 25 is fixedly installed at the bottom of the spring damper 24.

[0030] Adjustment holes 22 are formed in the middle of the inner cavity of each base column frame 21. The inner wall of the adjustment hole 22 is provided with threads that match the shape of the outer surface of the adjustment rod 23. The height of the adjustment rod 23 and the height of the inner cavity of the adjustment hole 22 are both greater than the height of the base column frame 21. Therefore, when in use, by using the detachable adjustment rod 23 and its bottom structure, if the placement position of the grandstand body 1 and the grandstand extension 20 is uneven, the height of the grandstand body 1 and the grandstand extension 20 can be adjusted to a horizontal position by installing the adjustment rod 23 and controlling the height of the adjustment rod 23 after installation. This, together with the spring damper 24, improves the stability of the grandstand body 1 and the grandstand extension 20 during use.

[0031] Working principle: During operation, the entire structure is first correctly assembled. Then, multiple workers use crossbars and fixing straps to move the assembled device to the sports field to be used via a transport vehicle or other means. Next, a worker uses a puller to stretch and rotate the circular plate 19 to the right until the left circular block 14, connected to the left side of the circular plate 19 by the circular rod 16, moves to the right side of the inner cavity of the cylindrical cavity 10, and the locking block 15 extends into the inner cavity of the locking hole 11. At this time, the circular plate 19 can drive the threaded rod 9 to rotate through the circular rod 16 and the locking block 15. In turn, rotating the threaded rod 9 moves the slider 4 and the stand extension 2, which is fixedly connected to its bottom, to the track. The structure 0 is pushed to the left until the grandstand extension 20 moves to a suitable position on the left. Then, the circular plate 19 is moved to the left and inserted into the inner cavity of the mounting hole 8 by the pull groove, so that the locking block 15 is separated from the locking hole 11. At this time, the rotation of the circular plate 19 and the circular rod 16 will not affect the rotation of the threaded rod 9, thereby improving the stability of the grandstand extension 20 after adjustment. At the same time, the circular plate 19 is rotated until the limiting block 18 is inserted into the inner cavity of the limiting hole 7. The circular plate 19 is used to block and shield the circular rod 16 while preventing the circular plate 19 from easily rotating on its own. This achieves the effect of facilitating the rapid retraction of the stadium grandstand, making it convenient for subsequent transportation or simple and quick assembly, and improving the overall work efficiency.

[0032] During installation, the adjustable rod 23 and its bottom structure are detachably installed. When the placement of the main body 1 and the extension 20 of the grandstand is uneven, a large number of staff members support and lift the uneven parts. Then, the adjustable rod 23 is rotated and installed into the inner cavity of the adjusting hole 22. During the installation process, the height of the adjustable rod 23 after installation is controlled to adjust the main body 1 and the extension 20 of the grandstand to a horizontal position. The spring damper 24 is used to improve the stability of the main body 1 and the extension 20 of the grandstand during use.

[0033] When disassembly and relocation are required, a large number of workers lift the main body 1 and the extension 20 of the grandstand to facilitate the disassembly of the adjusted rod 23 and its bottom structure after installation. Then, the first step is repeated, and the circular plate 19 is stretched and rotated to the right. Through the locking block 15 and the locking hole 11, the circular rod 16 drives the threaded rod 9 to rotate in the opposite direction, thereby retracting the extension 20 into the inner cavity of the storage cavity 2. Then, the circular plate 19 is moved and rotated to the left, so that the circular plate 19 and the limiting block 18 extend into the inner cavity of the mounting hole 8 and the limiting hole 7. Finally, a large number of workers transport the retracted whole device to the top of a transport device such as a car, and the grandstand is moved and transported using the transport device such as a car.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
