Description

Technical Field

[0001] This utility model belongs to the field of boxing target technology, and specifically refers to a connection structure for a boxing target shaft. Background Technology

[0002] A boxing target is a sporting instrument used to train reaction speed and hand strength. Users achieve their sporting goals by striking the target with their hands and dodging. The middle part of a boxing target is usually a bar. Due to the need to accommodate the average height of users, the basic length of the bar is relatively long. This makes it difficult to transport and place after the bar is connected to the target, especially during storage and transportation. When small transport vehicles are crammed with other items, the bar is easily squeezed, and excessive compression can reduce its elasticity. Currently, there are boxing targets on the market with detachable connecting bars, where the middle bar is connected by a plug-in structure. However, the stability of this connection method is limited. When the user's hand strikes the target with greater force, the upper bar can easily detach from the lower bar. Therefore, there is a need for a boxing target with a detachable bar that reduces storage space during transportation, is easy to assemble, and provides a stable connection between the upper and lower bars after assembly. Summary of the Invention

[0003] The purpose of this invention is to provide a boxing target shaft that is simple in structure, can be disassembled, reduces storage space during transportation, is easy to assemble, and provides a stable connection between the upper and lower shafts after assembly.

[0004] The purpose of this utility model is achieved as follows:

[0005] A connecting structure for a boxing target shaft includes an upper shaft and a lower shaft. The upper shaft has a punching ball at its upper end, and the lower shaft has a base at its lower end. The lower end of the upper shaft has a connecting hole, and the upper end of the lower shaft has a connecting part. The lower shaft can extend into the connecting hole through the connecting part and connect with the upper shaft. The connecting hole has an internal thread, and the connecting part has an external thread. Driving the lower shaft to rotate relative to the upper shaft can be achieved by tightening the connection between the internal and external threads. The upper and lower shafts are respectively formed with a snap-fit ​​part and an anti-rotation part. The lower shaft is rotatably connected relative to the upper shaft, allowing the anti-rotation part to approach the snap-fit ​​part. The upper shaft has an anti-rotation component with an anti-rotation hole inside. The anti-rotation hole is adapted to the snap-fit ​​part and the anti-rotation part. The anti-rotation component snaps into the snap-fit ​​part through the anti-rotation hole and can move downward along the snap-fit ​​part until it snaps into the anti-rotation part. At this time, the inner wall of the anti-rotation hole abuts against the outer wall of the snap-fit ​​part and the anti-rotation part, thereby restricting the relative rotation of the upper and lower shafts.

[0006] Furthermore, the anti-rotation part is welded to the lower rod.

[0007] Furthermore, the anti-rotation part is a hexagonal nut.

[0008] Furthermore, the snap-fit ​​part is welded to the upper rod, the connecting hole is located inside the snap-fit ​​part, the length of the snap-fit ​​part is shorter than the length of the anti-rotation member, the anti-rotation member is provided with an abutment end, the anti-rotation member is driven to move downward relative to the lower rod, the abutment end can abut against the end of the snap-fit ​​part, and restrict the anti-rotation member from continuing to move downward, the snap-fit ​​part is a connecting post.

[0009] Furthermore, the surface of the anti-rotation component is also provided with several anti-slip parts.

[0010] Furthermore, the base is provided with a suction cup assembly, which includes a suction cup and a control rod. The control rod is rotatably connected to the suction cup, and driving the control rod to rotate relative to the suction cup can drive the suction cup to perform adsorption.

[0011] Furthermore, a bottom rod is vertically provided on the base, the lower rod is connected to the bottom rod, and an elastic spring is provided between the lower rod and the bottom rod.

[0012] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0013] This invention relates to a quick-disassembly and stable-connection structure for a boxing target bar. Compared to a non-detachable bar, this invention reduces space usage, providing better protection for the bar when transported in confined spaces like a car trunk. It prevents the bar's elasticity from being compromised by objects pressing against the center. Compared to previous plug-in bar designs, this invention offers a more stable connection. The screw-connected rotation makes it difficult for the user to separate the upper and lower bars during boxing. Disassembly is simple: just hold the upper and lower bars and rotate them relative to each other. An anti-rotation device on the upper bar effectively restricts rotation, preventing injury to the hands during exercise. The impact of the upper rod causes it to rotate relative to the lower rod. The anti-rotation component has an anti-rotation hole that matches the locking part and the anti-rotation part. When the anti-rotation component moves to cover the locking part, the upper rod rotates independently and simultaneously drives the anti-rotation component to rotate. When the anti-rotation component moves downward until the anti-rotation hole inside the anti-rotation component engages with the anti-rotation part, the upper rod, the anti-rotation component, and the lower rod are in a state of synchronous rotation. The lower rod can no longer rotate independently relative to the upper rod. When disassembly is required, simply move the anti-rotation component upward to release it from the restriction of the anti-rotation part, and the lower rod can then rotate and separate relative to the upper rod. This utility model is quick and convenient to disassemble, as it only requires moving up and down to restrict both parts, making it more convenient than other connection and locking methods.

Detailed Implementation

[0023] The present invention will be further described below with reference to specific embodiments:

[0024] A connecting structure for a boxing target shaft includes an upper shaft 1 and a lower shaft 2. The upper shaft 1 has a punching ball 13 at its upper end, and the lower shaft 2 has a base 14 at its lower end. The lower end of the upper shaft 1 has a connecting hole 3, and the upper end of the lower shaft 2 has a connecting part 4. The lower shaft 2 can extend into the connecting hole 3 through the connecting part 4 to connect with the upper shaft 1. The connecting hole 3 has an internal thread, and the connecting part 4 has an external thread. Driving the lower shaft 2 to rotate relative to the upper shaft 1 allows for tightening through the internal and external thread connections. The upper shaft 1 and lower shaft 2 are respectively formed with… The locking part 7 and the anti-rotation part 8 are connected to the lower rod 2 relative to the upper rod 1, allowing the anti-rotation part 8 to approach the locking part 7. The upper rod 1 is provided with an anti-rotation member 9, which has an anti-rotation hole 10. The anti-rotation hole 10 is adapted to the locking part 7 and the anti-rotation part 8. The anti-rotation member 9 is locked with the locking part 7 through the anti-rotation hole 10 and can move downward along the locking part 7 until it is locked with the anti-rotation part 8. At this time, the inner wall of the anti-rotation hole 10 abuts against the outer wall of the locking part 7 and the anti-rotation part 8, thereby restricting the relative rotation of the upper rod 1 and the lower rod 2.

[0025] This invention relates to a quick-disassembly and stable-connection structure for a boxing target bar. Compared to a non-separable bar, this invention reduces space usage, providing better protection for the bar when transported in confined spaces like a car trunk, preventing the middle section from being squeezed by other objects and losing elasticity. Compared to previous plug-in bar designs, this invention offers a more stable connection. The screw-connected rotation makes it difficult for the user to separate the upper bar 1 and lower bar 2 during boxing. Disassembly is simple: just hold the upper bar 1 and lower bar 2 and rotate them relative to each other. The anti-rotation element 9 on the upper bar 1 effectively restricts the rotation of the upper bar 1 and lower bar 2, preventing the hand from striking the target during movement. This causes the upper rod 1 to rotate relative to the lower rod 2. The anti-rotation part 9 is provided with an anti-rotation hole 10 that matches the locking part 7 and the anti-rotation part 8. When the anti-rotation part moves to wrap around the locking part 7, the upper rod 1 will rotate alone and simultaneously drive the anti-rotation part 9 to rotate. When the anti-rotation part 9 moves downward until the anti-rotation hole 10 in the anti-rotation part 9 engages with the anti-rotation part 8, the upper rod 1, the anti-rotation part 9 and the lower rod 2 are in a state of synchronous rotation. The lower rod 2 can no longer rotate relative to the upper rod 1. When disassembly is required, simply move the anti-rotation part 9 upward to release it from the restriction of the anti-rotation part 8, and the lower rod 2 can rotate and separate relative to the upper rod 1. This utility model is quick and convenient to disassemble. It only requires moving up and down to restrict the two, which is more convenient than other connection and locking methods.

[0026] Preferably, the anti-rotation part 8 is welded to the lower rod 2, forming an integral part without the need for other parts to lock the connection between the two.

[0027] Preferably, the anti-rotation part 8 is a hexagonal nut, which limits rotation by its shape, and the polygonal shape makes the connection more stable.

[0028] Preferably, the locking part 7 is welded to the upper rod 1, the connecting hole 3 is provided in the locking part 7, the length of the locking part 7 is shorter than the length of the anti-rotation member 9, the anti-rotation member 9 is provided with an abutment end 11, driving the anti-rotation member 9 to move downward relative to the lower rod 2, the abutment end 11 can abut against the end of the locking part 7 and restrict the anti-rotation member 9 from continuing to move downward, the locking part 7 is a connecting post, the length of the connecting post is shorter than the length of the anti-rotation member 9, restricting the anti-rotation member 9, when the anti-rotation member 9 moves downward, the connecting post and the hexagonal nut can be wrapped and locked together, the abutment end 11 in the anti-rotation member 9 can restrict the anti-rotation member 9 from moving downward too much, and prevent the anti-rotation member 9 from failing to lock the upper rod 1 and the lower rod 2 at the same time.

[0029] Preferably, the surface of the anti-rotation member 9 is also provided with a plurality of anti-slip parts 12 to prevent the hand from slipping on the anti-rotation member 9 when the hand controls the anti-rotation member 9 to move downward, thereby increasing the friction between the hand and the anti-rotation member 9.

[0030] Preferably, the base 14 is provided with a suction cup assembly 15, which includes a suction cup 16 and a control rod 17. The control rod 17 is rotatably connected to the suction cup 16. Driving the control rod 17 to rotate relative to the suction cup 16 can drive the suction cup 16 to adhere. By adhering to the ground through the suction cup assembly 15, driving the control rod 17 to rotate can drive the suction cup 16 to adhere to the ground, making it suitable for users to practice. The suction cup 16 is a commonly used suction cup 16 on the market.

[0031] Preferably, a base rod 18 is vertically mounted on the base 14, and the lower rod 2 is connected to the base rod 18. An elastic spring 19 is connected between the lower rod 2 and the base rod 18, providing a buffer and rebound between them. If the lower rod 2 and the base rod 18 were directly and rigidly connected, long-term exposure to high-intensity impacts could lead to loosening, deformation, or even breakage at the connection. The buffering effect of the elastic spring 19 effectively alleviates this impact force, reduces pressure on the connection part 4, lowers the possibility of equipment damage, and improves the stability and reliability of the equipment.

[0032] 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.
