[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.

[0028] Examples, such as Figure 1-8 As shown, a parkour-style jumping box structure includes a box with its opening facing downwards. A central lifting cylinder 1, capable of being raised and lowered, is installed inside the box. The central lifting cylinder 1 can be any existing cylinder. A suspension 11 is connected to the lower end of the central lifting cylinder 1, and wheels 12 are mounted on the suspension 11. The suspension 11 and wheels 12 can be existing wheel-based agility components. In this structure, simply operating the central lifting cylinder 1 raises or lowers the box to change its position. Initially, the box is flat on the ground. The bottom surface of the box is preferably roughened or secured with pins that can be inserted into the ground to prevent easy movement. When the central lifting cylinder 1 is activated, the box rises, supported by the wheels 12, making it easy to push and move around. Operating only the central lifting cylinder 1 is sufficient, making it very labor-saving and convenient.

[0029] Preferably, the box body includes a front panel 21, a left panel 22, a rear panel 23, and a right panel 24 connected sequentially from front to back and left to right, and a top panel 25 fixedly connected to the top of the front panel 21, left panel 22, rear panel 23, and right panel 24. The front panel 21, left panel 22, rear panel 23, right panel 24, and top panel 25 surround and form a box interior space 20 with the opening facing downwards. The front panel 21, left panel 22, rear panel 23, right panel 24, and top panel 25 can be made of wood. Furthermore, a reinforcing beam frame is fixed below the top plate 25 within the box space 20. The reinforcing beam frame is composed of front beam 31, left beam 32, rear beam 33, and right beam 34 connected sequentially. The reinforcing beam frame can be made of steel beams. The front beam 31, left beam 32, rear beam 33, and right beam 34 can be made of square steel beams or I-beams. The four beams can be connected and fixed sequentially by welding, integral molding, or bolt fixing. Of course, each beam also needs to be fixed to the box body. Existing fixing methods can be used, such as fixing by screws or bolts. For example, countersunk bolts can be threaded through the top plate and front beam 31. A nut can be added to the lower end of the countersunk bolt for reinforcement. The front beam 31, left beam 32, rear beam 33, and right beam 34 are all fixed to the lower side of the top plate 25 and abut against the inner side of the corresponding box plate. For example, the front side of the front beam 31 abuts against the rear side of the front plate 21. That is, each beam is at the junction corner of the top plate and the corresponding side plate. The side plates refer to the front plate 21, left plate 22, rear plate 23, and right plate 24. This structure has a reinforcing effect on the box body, and the reinforced beam frame is used to install subsequent moving structures, etc., and the strength will be more reliable.

[0030] Preferably, a left reinforcing column 41 is fixed to the lower side of the left beam 32, and a right reinforcing column 42 is fixed to the lower side of the right beam 34. A central support plate 43 is fixed between the left and right reinforcing columns 41 and 42. The left and right reinforcing columns 41 and 42 and the central support plate 43 can be made of steel, and the central support plate 43 can be a square or round plate. The central support plate 43 is fixed to the lifting rod 101 above the central lifting cylinder 1. The lifting rod 101 can pass upward through the central support plate 43 and be welded to the outer wall of the central support plate 43. The suspension 11 is fixed to the cylinder body 102 below the central lifting cylinder 1, and the suspension 11 can be welded to the bottom of the cylinder body 102.

[0031] Preferably, the upper part of the lifting rod 101 has a switch bolt guide rod 103, and the upper end of the switch bolt guide rod 103 is connected to a first adjusting control rod 104. The first adjusting control rod 104 extends backward and upward. The existing cylinder structure includes two main parts: the lifting rod 101 and the cylinder body 102. The upper part of the lifting rod 101 has a switch bolt guide rod 103. Lifting and lowering can be achieved by operating the switch bolt guide rod 103. The purpose of designing the first adjusting control rod 104 is similar to the structure of a height-adjustable chair. The first adjusting control rod 104 drives the switch bolt guide rod 103 to move downward, and the switch bolt is opened. Through the action of internal air pressure, the lifting rod 101 is lifted, and the box body is also lifted, so that the traveling wheels can support the movement of the box body. Of course, at this time, the first adjusting control rod 104 drives the switch bolt guide rod 103 to reset, so that the air pressure in the cylinder body is maintained, and the box body is stably lifted. When moved to the designated location, the first adjustment control lever 104 is operated again to move the switch bolt guide rod 103 downward. At this time, press down on the cabinet with your hand to make it move downward, or sit on the cabinet to apply downward pressure, which is the same as operating a lifting chair. Once the front panel 21, left panel 22, rear panel 23, and right panel 24 are on the ground, operate the first adjustment control lever 104 again to reset the switch bolt guide rod 103, thus stopping the cabinet on the ground and making it ready for use. The bottom surfaces of the front panel 21, left panel 22, rear panel 23, and right panel 24 have a rough surface and can be further secured with ground nails and other structures for more stable contact with the ground.

[0032] Furthermore, the rear plate 23 has an operation window 230 for inserting the rear end of the first adjustment control lever 104. A central operation auxiliary lever 431 is fixed to the rear side of the central support plate 43. The first adjustment control lever 104 and the central operation auxiliary lever 431 are crossed and rotatably connected. The upper part of the lifting rod 101 of the central lifting cylinder 1 extends upward beyond the central support plate 43 and is located above the central support plate 43. This design makes the operation of the first adjustment control lever 104 convenient and concealed, and does not affect normal use. The central operation auxiliary lever 431 provides lever-type drive for the first adjustment control lever 104.

[0033] Preferably, there are multiple left reinforcing columns 41 and right reinforcing columns 42, which are arranged in a left-right pair. A front support plate 51 is fixed between one set of left reinforcing columns 41 and right reinforcing columns 42. A downwardly extending front lifting cylinder 52 is fixed on the front support plate 51. A left-right extending front crossbar 53 is fixed to the lower end of the front lifting cylinder 52. A front support foot 54 is connected to the left and right sides of the front crossbar 53. A rear support plate 61 is fixed between one set of left reinforcing columns 41 and right reinforcing columns 42. A downwardly extending rear lifting cylinder 62 is fixed on the rear support plate 61. A left-right extending rear crossbar 63 is fixed to the lower end of the rear lifting cylinder 62. A rear support foot 64 is connected to the left and right sides of the rear crossbar 63. The principle is the same as the design of the aforementioned central lifting cylinder 1, except that a lifting structure is further added to the front and rear sides of the central support plate 43. Taking the front structure as an example, the front support plate 51 can be fixedly connected to the lifting rod of the front lifting cylinder 52. The bottom of the cylinder body of the front lifting cylinder 52 is fixed to the front crossbar 53. The front support foot 54 can be fixed to the front crossbar 53 using existing support feet. The front crossbar 53 can also be a steel rod. The corresponding connection structure of the rear support foot 64 can be the same as the front side. Of course, the lifting rods of the front and rear lifting cylinders also have switch bolt guide rods. By controlling the switch bolt guide rods, the lifting of the front and rear lifting cylinders can be controlled. The lifting of these two cylinders is so that when the parkour box needs to be at a higher height and has different height adjustments, it needs to be lifted off the ground to the corresponding height. The operation is also relatively simple. After the box is transported to the designated location as described above, it is controlled to be used close to the ground. If it needs to be raised, the front and rear lifting cylinders are controlled to rise, which will lift the box. Then the switch bolt guide rod is reset to maintain pressure. When not in use, simply reopen the switch rod guide, then press down or sit on the enclosure to lower it to the ground, and then reset the switch rod guide. This also improves stability when used close to the ground, as the support feet also contact the ground, increasing the contact area and reducing the likelihood of slippage or displacement.

[0034] Preferably, the front lifting cylinder 52 is controlled by the second adjusting control lever 50, and the rear lifting cylinder 62 is controlled by the third adjusting control lever 60. That is, the second adjusting control lever 50 is connected to the switch bolt guide rod of the front lifting cylinder 52, and the third adjusting control lever 62 is connected to the rear lifting cylinder 62. This achieves control. Of course, corresponding front and rear support plates also need to be fixed with upright auxiliary rods. The corresponding auxiliary rods are crossed and rotatably connected to the second adjusting control lever 50 or the third adjusting control lever 60 to provide lever driving force.

[0035] Furthermore, both the second adjustment control lever 50 and the third adjustment control lever 60 extend to the upper left or to the upper right to avoid interference between the structures, thus eliminating the need to avoid the first adjustment control lever 104.

[0036] Furthermore, the left plate 22 or the right plate 24 has a second operating window 2241 for inserting the end of the second adjustment control lever 50, and the left plate 22 or the right plate 24 also has a third operating window 2242 for inserting the end of the third adjustment control lever 60. The windows are designed to be concealed to ensure structural integrity and not affect use. Of course, for better design, an openable window can be installed and connected to the operating window, which would improve the integrity even further. In addition, a connecting rod can be connected between the second adjustment control lever 50 and the third adjustment control lever 60, so that only one control lever needs to be operated, and they can be operated synchronously, which would improve the effect.

[0037] Preferably, the front support foot 54 and the rear support foot 64 are elastic support feet. Existing elastic support feet can be used. This design is so that when the parkour box needs to be used elastically, it can be used without setting up a special elastic box body, which makes it more versatile.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
