Description

Technical Field

[0001] This utility model belongs to the field of trampoline technology, specifically relating to a trampoline spring disassembly and assembly tool. Background Technology

[0002] Springs are an essential component of trampoline equipment, connecting the trampoline frame to the jumping mat. Currently, when installing trampoline springs, operators typically first hook one end of the spring onto the hanging ring on the edge of the jumping mat, then pull the other end of the spring to hook it into the hanging hole on the trampoline frame. When removing trampoline springs, operators must first stretch the spring to disengage one end of the hook from the frame hanging hole, then remove the other end of the spring from the hanging ring on the jumping mat.

[0003] However, due to the high rigidity and large number of trampoline springs, the installation and disassembly of trampoline springs are difficult and labor-intensive for operators with relatively less strength. Often, operators with great strength are required to install and disassemble trampoline springs, which has great limitations and is not conducive to the promotion and use of the product.

[0027] Example 1:

[0028] refer to Figures 1-2 As shown, this utility model provides a trampoline spring assembly / disassembly tool for installing and removing springs 30 from a trampoline. The tool includes a pull hook 41, a limiting pin 43, and an assist rod 42.

[0029] The lever hook 41 includes a rod portion 411 and a hook portion 412 connected to one end of the rod portion 411 along its length. The hook portion 412 is used to engage with the hook at the end of the spring 30. The rod portion 411 is cylindrical, and a limiting hole 413 is provided through the end of the rod portion 411 away from the hook portion 412. The length direction of the limiting hole 413 is perpendicular to the length direction of the rod portion 411.

[0030] The limiting pin 43 is detachably inserted into the limiting hole 413; it is understood that the shape and size of the limiting pin 43 are adapted to the limiting hole 413. Both ends of the limiting pin 43 protrude from the rod portion 411 of the pull rod hook 41.

[0031] The assist rod 42 is sleeved outside the rod portion 411 of the pull rod hook 41, and the length direction of the assist rod 42 is perpendicular to the length direction of the rod portion 411 of the pull rod hook 41. It can be understood that the outer dimension of the assist rod 42 is larger than the outer diameter of the rod portion 411 of the pull rod hook 41, and the assist rod 42 has a circular through hole that matches the outer wall of the rod portion 411 of the pull rod hook 41. The assist rod 42 is located between the limiting pin 43 and the hook portion 412 of the pull rod hook 41. The assist rod 42 can reciprocate along the length direction of the rod portion 411 of the pull rod hook 41, and the assist rod 42 can also rotate around the rod portion 411 of the pull rod hook 41. The length of one end of the assist rod 42 protruding outside the rod portion 411 of the pull rod hook 41 is greater than the length of the rod portion 411 of the pull rod hook 41. This end is called the force-applying end of the assist rod 42. It should be noted that when the assist rod 42 moves to press against the limit pin 43, the minimum distance between the assist rod 42 and the hook part 412 should be greater than the distance between the inner edge of the hanging hole 21 of the trampoline frame 20 and the outer edge of the trampoline frame 20.

[0032] To further explain, when the operator installs the trampoline spring 30 using this embodiment, first hook one end of the spring 30 onto the hanging ring 11 on the edge of the jumping mat 10, and then hook the other end of the spring 30 onto the bent hook portion 412 of the pull rod hook 41. At this time, the assist rod 42 is located on the outside of the trampoline frame 20. The operator pulls the force-applying end of the assist rod 42 outward, and the assist rod 42 presses against the limiting pin 43. The rod portion 411 of the pull rod hook 41 presses against the trampoline frame 20. Continue pulling the assist rod 42 to overcome... The spring force causes the hook part 412 of the pull rod hook 41 to drive the hook of the spring 30 to deflect around the point where the rod part 411 of the pull rod hook 41 is pressed against the trampoline frame 20, until the hook of the spring 30 reaches above and aligns with the hanging hole 21 of the trampoline frame 20. Then, the assist rod 42 is slowly released, so that the hook of the spring 30 hooks downward into the hanging hole 21 of the trampoline frame 20. Then, the hook part 412 of the pull rod hook 41 is withdrawn from the hook of the spring 30, thus completing the installation of the spring 30 between the trampoline frame 20 and the jumping mat 10. When the operator disassembles the trampoline spring 30 using this embodiment, first use the hook part 412 of the pull rod hook 41 to hook the hook end of the spring 30 that is attached to the trampoline frame 20, and pull the assist rod 42 outward to overcome the spring force, so that the hook part 412 of the pull rod hook 41 drives the hook of the spring 30 to deflect around the point where the rod part 411 of the pull rod hook 41 and the trampoline frame 20 are pressed together, so that the hook of the spring 30 is disengaged from the hanging hole 21 of the trampoline frame 20. Then, release the assist rod 42 to allow the spring 30 to return to its natural state, remove the hook part 412 of the pull rod hook 41 from the hook of the spring 30, and then remove the hook at the other end of the spring 30 from the hanging ring 11 of the jumping mat 10, thereby completing the disassembly of the trampoline spring 30. As mentioned above, when installing and removing the trampoline spring 30, the operator's force application end is located at the end of the longer assist rod 42. Therefore, a lever effect is formed between the pull rod hook 41, the trampoline frame 20 and the assist rod 42, which increases the operator's force arm and reduces the force required to install and remove the spring 30. Thus, the operator can install and remove the trampoline spring 30 without much force.

[0033] In the above illustrative embodiment, the installation and disassembly of the trampoline spring 30 can be reduced by the setting of the assist rod 42, making it easier for operators of different strengths to install and disassemble the trampoline spring 30, reducing the labor intensity of the operators, and improving the installation and disassembly efficiency of the trampoline spring 30; the setting of the limit pin 43 provides a limit for the assist rod 42 and prevents the assist rod 42 from detaching from the pull rod hook 41, making it easier to maintain the integrity of the disassembly and assembly tools to prevent the loss of parts.

[0034] refer to Figure 1As shown, in some embodiments, the end of the lever hook 41 411 opposite to the hook portion 412 is provided with a plurality of limiting holes 413 spaced apart along the length direction of the lever portion 411; by inserting the limiting pin 43 into different limiting holes 413, the distance between the assist rod 42 and the hook portion 412 is adjusted, that is, the operator's force arm is adjusted, so that the disassembly and assembly tool can more flexibly adapt to the installation and disassembly needs of trampoline springs 30 of different lengths and hardnesses.

[0035] refer to Figure 1 As shown, in some embodiments, the limiting hole 413 is a circular hole or a polygonal hole, and the shape of the limiting pin 43 is adapted to the limiting hole 413. In some embodiments, the assist rod 42 is a hollow rod to reduce the weight of the assist rod 42 and achieve a lightweight design for the disassembly and assembly tool. In some embodiments, the assist rod 42 is cylindrical or prismatic in shape, which can provide the operator with different tool usage experiences and choices.

[0036] In some embodiments, the longer end of the assist rod 42 protruding from the rod portion 411 of the lever hook 42 is provided with an anti-slip handle (not shown), that is, the anti-slip handle is provided at the force-applying end of the assist rod 42 to increase the operator's grip stability.

[0037] Example 2:

[0038] Based on Embodiment 1, the lever hook 41 rod portion 411 is configured as a prism shape, and the assist rod 42 sleeved outside the rod portion 411 has a polygonal through hole adapted to the outer wall of the lever hook 41 rod portion 411. The length direction of the assist rod 42 is perpendicular to the plane where the center line of the hook portion 412 of the lever hook 41 is located. Therefore, the assist rod 42 can only move back and forth along the length direction of the lever hook 41 rod portion 411, but there will be no relative rotation between the assist rod 42 and the lever hook 41 rod portion 411. This makes the positional relationship between the lever hook 41 and the assist rod 42 relatively stable, which can provide the operator with different tool usage experiences and choices.

[0039] In summary, the trampoline spring assembly and disassembly tool of this utility model has a simple structure and strong practicality. It can reduce the difficulty of installing and disassembling the trampoline spring 30, making it easy for operators of different strengths to install and disassemble the trampoline spring 30, reducing the labor intensity of operators, improving the efficiency of installing and disassembling the trampoline spring 30, and facilitating the promotion and use of trampoline products.

[0040] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0041] The above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
