Description

Technical Field

[0001] This utility model belongs to the field of trampoline technology, and specifically relates to a trampoline with adjustable resistance. Background Technology

[0002] Trampolines are a type of sports equipment, and children use them for jumping activities in daily life.

[0003] Currently, trampolines on the market typically use springs to connect the trampoline net and frame. Because there are many springs, the resistance of the trampoline net cannot be adjusted after installation. When replacement or adjustment of the resistance is needed, the springs must be disassembled and replaced with springs of different tensions, which is very inconvenient. While Chinese utility model patent CN 219558605 U discloses a connection structure for the trampoline net surface that uses a first connecting block and a second connecting block to disassemble and replace the springs, this structure still cannot achieve adjustment of the trampoline net's resistance.

[0004] Therefore, a trampoline with adjustable resistance for the trampoline net is needed. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a trampoline with adjustable resistance.

[0006] The purpose of this utility model is achieved as follows:

[0007] An adjustable resistance trampoline includes a frame and a trampoline fabric connected to the frame, and also includes an elastic element, a connector and an adjustment element disposed on the frame;

[0008] One end of the elastic element is connected to the trampoline fabric, and the other end of the elastic element is movably connected to the connecting element; the movable end of the adjusting element is connected to the connecting element, and the inward and outward movement of the movable end of the adjusting element drives the connecting element to move inward and outward, thereby causing the elastic element to adjust the tightness of the trampoline fabric.

[0009] The adjustment component is further configured such that: the adjustment component includes a housing fixedly mounted on the frame and a drive rod with one end extending into the housing; the drive rod is threadedly connected to the housing; one end of the drive rod is connected to a connecting component; rotating the drive component moves it inward or outward along the axial direction of the housing.

[0010] The adjustment component is further configured such that: the adjustment component includes a housing fixedly mounted on the frame and a drive rod with one end extending into the housing; the drive rod is externally threaded to a movable component, which is connected to a connecting component; rotating the drive component causes the movable component to move inward or outward along the axial direction of the housing.

[0011] The further configuration is as follows: a movable groove is provided on the housing, and a limiting protrusion is provided on the movable part extending into the movable groove. The limiting protrusion moves axially within the movable groove and restricts the radial rotation of the movable part.

[0012] The adjustment member is further configured to include a safety mechanism that restricts the axial movement of the movable end of the adjustment member.

[0013] The safety mechanism includes an operating disc sleeved outside the driving component. The operating disc has a fixed protrusion, and the housing has a fixing groove that interlocks with the fixed protrusion. When the fixed protrusion and the fixing groove are interlocked, the rotation of the driving component is restricted. When the operating disc moves along the axial direction of the driving component, the fixed protrusion and the fixing groove disengage, and rotating the operating disc drives the driving component to rotate.

[0014] A further configuration is provided: the operation panel is provided with a non-circular through hole, through which the driving component passes.

[0015] The frame is further configured such that a first guide wheel is provided on the frame, and the connecting piece is rotatably connected to the inner side of the first guide wheel.

[0016] The adjustment member is further configured such that one end extends into the interior of the frame, and a second guide wheel is provided on both sides of the end of the adjustment member, and the connecting member is rotatably connected to the outer side of the second guide wheel.

[0017] A further configuration is provided: a third guide wheel is provided at the other end of the elastic element, and the third guide wheel is located between the two first guide wheels.

[0018] The configuration is further defined as follows: at least three elastic elements are equidistantly arranged, and the elastic elements and the first guide wheel are spaced apart.

[0019] The advantages of this utility model over the prior art are as follows:

[0020] 1. The elastic element connects the connecting part and the adjusting part, and the movement of the adjusting part can tighten or loosen the elastic element on the trampoline cloth, thereby realizing the adjustment of the trampoline resistance. Users can adjust the tightness of the trampoline cloth according to their own weight or needs without disassembling the elastic element. At the same time, even if disassembly and installation are very convenient, simply loosen the adjusting part and the connecting part to disengage the elastic element from the connecting part.

[0021] Second, the connecting parts can be adjusted by setting a drive rod; and the radial restriction of the moving parts can be achieved by the cooperation of the limiting protrusion and the moving groove, so that the moving parts can only move axially, which facilitates the tightening and loosening of the connecting parts.

[0022] Third, by setting the first guide wheel, the second guide wheel and the third guide wheel, the connection can be made smoother during the tightening and loosening process. Attached Figure Description

[0034] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0035] See Figures 1 to 6 As shown, an adjustable resistance trampoline includes a frame 1 and a trampoline cloth 2 connected to the frame 1, and also includes an elastic element 3, a connecting element 4, and an adjusting element 5 disposed on the frame 1; the elastic element 3 can be a tension spring, elastic rope, hydraulic spring, etc., and in this embodiment, the elastic element 3 is preferably a tension spring; the connecting element 4 can be a steel wire rope, elastic rope, fiber rope, synthetic rope, etc., and in this embodiment, the connecting element 4 is preferably a steel wire rope;

[0036] One end of the elastic element 3 is connected to the trampoline fabric 2, and the other end of the elastic element 3 is movably connected to the connecting element 4. The movable end of the adjusting element 5 is connected to the connecting element 4. The inward and outward movement of the movable end of the adjusting element 5 drives the connecting element 4 to move inward and outward, thereby causing the elastic element 3 to adjust the tension of the trampoline fabric 2. By connecting the connecting element 4 and the adjusting element 5 through the elastic element 3, the elastic element 3 can tighten or loosen the trampoline fabric 2 through the movement of the adjusting element 5, thus realizing the adjustment of the resistance of the trampoline. Users can adjust the tension of the trampoline fabric 2 according to their own weight or needs without disassembling the elastic element 3. At the same time, even if disassembly and installation are performed, it is very convenient. Just loosen the adjusting element 5 and the connecting element 4 to disengage the elastic element 3 from the connecting element 4.

[0037] There are many ways to structure the adjusting member 5. The connecting member 4 can be loosened or tightened inward or outward. In this embodiment, the adjusting member 5 can have the following structure:

[0038] Structure 1:

[0039] The adjusting component 5 includes a housing 51 fixedly mounted on the frame 1 and a drive rod 53 with one end extending into the housing 51. The drive rod 53 is threadedly connected to the housing 51, and one end of the drive rod 53 is connected to the connecting component 4. Rotating the drive component moves it inward or outward along the axial direction of the housing 51.

[0040] To make the connection 4 loosening and tightening smoother, a fixing member for fixing the connection 4 is movably provided on the drive member. The fixing member (not shown in the attached figure) can rotate relative to the drive member, so that the connection 4 can move axially like the drive rod 53 without getting tangled.

[0041] Rotating the drive rod 53 causes the housing 51 to rotate, thus moving it inward or outward, which in turn loosens or tightens the connector 4.

[0042] To prevent the drive component from rotating in the locked state, a safety mechanism is provided on the adjusting component 5 to limit the axial movement of the movable end of the adjusting component 5;

[0043] The safety mechanism includes an operating disc 56 sleeved on the drive component. The operating disc 56 is provided with a fixing protrusion 61, and the housing 51 is provided with a fixing groove 62 that interlocks with the fixing protrusion 61. After the fixing protrusion 61 and the fixing groove 62 are interlocked, the rotation of the drive component is restricted. When the operating disc 56 moves along the axial direction of the drive component, the fixing protrusion 61 and the fixing groove 62 are disengaged, and rotating the operating disc 56 drives the drive component to rotate.

[0044] The operating disk 56 is provided with a non-circular through hole 57, through which the driving component passes, so that the operating disk 56 is less likely to slip during rotation.

[0045] Structure 2:

[0046] like Figures 3-6 The adjusting component 5 includes a housing 51 fixedly mounted on the frame 1 and a drive rod 53 with one end extending into the housing 51. The drive rod 53 is externally threaded with a movable component 54, which is connected to the connecting component 4. Rotating the drive component causes the movable component 54 to move inward or outward along the axial direction of the housing 51.

[0047] The housing 51 is provided with a moving groove 52, and the movable part 54 is provided with a limiting protrusion 55 extending into the moving groove 52. The limiting protrusion 55 moves axially within the moving groove 52 and restricts the radial rotation of the movable part 54. There are two limiting protrusions 55, so that the movable part 54 can maintain the stability of axial movement when it is driven by the thread of the driven part.

[0048] Furthermore, the radial restriction of the movable part 54 is achieved through the cooperation of the limiting protrusion 55 and the moving groove 52, so that the movable part 54 can only move axially, which facilitates the tightening and loosening of the connecting part 4 and makes the operation relatively easy.

[0049] To prevent the drive component from rotating in the locked state, the adjusting component 5 is provided with a safety mechanism that restricts the axial movement of the movable end of the adjusting component 5;

[0050] The safety mechanism includes an operating disc 56 sleeved on the drive component. The operating disc 56 is provided with a fixing protrusion 61, and the housing 51 is provided with a fixing groove 62 that interlocks with the fixing protrusion 61. After the fixing protrusion 61 and the fixing groove 62 are interlocked, the rotation of the drive component is restricted. When the operating disc 56 moves along the axial direction of the drive component, the fixing protrusion 61 and the fixing groove 62 are disengaged, and rotating the operating disc 56 drives the drive component to rotate.

[0051] The operating disk 56 is provided with a non-circular through hole 57, through which the driving component passes, so that the operating disk 56 is less likely to slip during rotation.

[0052] Meanwhile, the operating disc 56 can move axially relative to the driving component. When it needs to be opened, the operating disc 56 is first moved outward along the driving component, the fixed protrusion 61 is disengaged from the fixed groove 62, and then the operating disc 56 is rotated. The operating disc 56 drives the driving component to rotate, and the driving component drives the movable component 54 to rotate. The limiting protrusion 55 of the movable component 54 moves back and forth in the moving groove 52.

[0053] To facilitate smooth tensioning or loosening of connector 4, a guide wheel is provided at the connection point with connector 4. The guide wheel has a guide groove circumferentially provided for connector 4 to fit, and connector 4 slides within the guide groove. The specific structure is as follows:

[0054] The frame 1 is provided with a first guide wheel 71, and the connector 4 is rotatably connected to the inner side of the first guide wheel 71; the first guide wheel 71 is connected to the frame 1 through the two sides of the fixed hook 8, and the first guide wheel 71 can rotate relative to the fixed hook 8.

[0055] One end of the adjusting member 5 extends into the interior of the frame 1, and a second guide wheel 72 is provided on both sides of the end of the adjusting member 5. The connecting member 4 is rotatably connected to the outer side of the second guide wheel 72.

[0056] The other end of the elastic element 3 is provided with a third guide wheel 73, which is located between the two first guide wheels 71. In this way, when the adjusting member 5 adjusts the tightness, the third guide wheel 73 is pulled outward by the connecting member 4, and the elastic element 3 can adaptively adjust the tensioning connection position relative to the connecting member 4.

[0057] At least three elastic elements 3 are equidistantly arranged, and the number of elastic elements 3 can be set to three, four or even more as needed; the elastic elements 3 and the first guide wheel 71 are spaced apart; in this embodiment, the frame 1 is circular, and thirty elastic elements 3 are equidistantly connected to the connecting member 4. The elastic elements 3 and the connecting member 4 cooperate to tighten the trampoline cloth 2. The adjusting member 5 is set between any two elastic elements 3. By rotating the operating disc 56, the connecting member 4 is driven by the driving member and moves inward or outward. Only by rotating the operating disc 56 can the entire elastic element 3 be relaxed or tightened. The overall structure is simple and easy to operate.

[0058] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
