[0002] Boxing, as a sport and a new form of fitness, is widely loved by the public, and more and more people are joining the sport. For both amateur enthusiasts and professional athletes, boxing requires a punching pad to practice.
[0003] Boxing targets are subjected to tremendous impact during use. To ensure stability and balance, traditional boxing targets often have their bottom fixed. This is extremely inconvenient from a storage and transportation perspective. Currently, advanced boxing targets on the market generally have a single metal base or a base shell plus an integrated counterweight, which is often very heavy, causing great inconvenience during disassembly and installation. Summary of the Invention
[0004] To address the aforementioned technical problems, this invention proposes a multifunctional boxing training device.
[0005] The technical solution of this invention is implemented as follows:
[0006] A multi-functional boxing training device, including: a boxing target, which is fixedly mounted on a boxing target frame.
[0007] A boxing target base, wherein the boxing target is detachably mounted on the boxing target base via a boxing target stand.
[0008] The counterweight unit is detachably installed inside the boxing target base. The counterweight unit includes multiple counterweight blocks, and two symmetrically distributed screw channels are opened on the counterweight blocks.
[0009] The connecting unit includes a connecting screw and a threaded groove. The threaded groove is formed on the inner wall of the boxing target base. The connecting screw passes through the screw channels on all the counterweights in sequence and then connects to the threaded groove.
[0010] Furthermore, the bottom of the counterweight is slidably provided with a support leg for supporting the counterweight, and the bottom of the support leg is embedded with a ball bearing for displacement of the support leg on the ground.
[0011] Furthermore, a reset rod is fixedly installed on the support leg at its end face. A rod sleeve is slidably fitted on the end of the reset rod away from the support leg. A reset spring is provided between the reset rod and the rod sleeve. A reset rod groove is opened on the end face of the counterweight block. The rod sleeve is slidably disposed in the reset rod groove, so that the rod sleeve can slide in the reset rod groove.
[0012] Furthermore, two locking rods are fixedly installed on the end face of the outrigger, and both locking rods are located below the reset rod in the height direction. The end face of the counterweight is provided with a locking rod groove, which is located below the reset rod groove, and is used to fix the outrigger and the counterweight when the locking rod is inserted.
[0013] Furthermore, the outrigger is provided with an unlocking unit, which is fixedly installed on the side of the outrigger. The unlocking unit includes an unlocking slider, an unlocking groove, and an unlocking spring. The unlocking slider is fixedly installed on the outrigger and slidably disposed in the unlocking groove, which is located on the side of the counterweight. An unlocking spring is disposed between the end of the unlocking slider away from the outrigger and the inner wall of the unlocking groove. The unlocking spring is located inside the unlocking groove. The unlocking unit is used to pull the locking rod out of the locking rod groove, thereby separating the outrigger from the counterweight.
[0014] Furthermore, a lifting unit is provided on the outrigger, which is fixedly installed on the side of the outrigger and located below the unlocking unit. The lifting unit includes a lifting slider, a lifting groove, and a lifting spring. The lifting slider is fixedly installed on the outrigger and slidably disposed in the lifting groove. The lifting groove is located on the side of the counterweight and below the unlocking groove. A lifting spring is provided between the end of the lifting slider away from the outrigger and the inner wall of the lifting groove. The lifting unit is used to lift the outrigger upward.
[0015] Furthermore, the positions of the outriggers near the unlocking slider and the lifting slider are both set at an angle. The surface of the unlocking slider near the outrigger is set as a first angle, which is used to displace the outrigger after contacting it to unlock it. The surface of the lifting slider near the outrigger is set as a second angle, which is used to displace the outrigger after contacting it to raise it relative to the counterweight.
[0016] Furthermore, the counterweight block is provided with a threaded sleeve limiting groove, which is opened on the inner side wall of the screw channel. Symmetrical limiting blocks are fixed in the threaded sleeve limiting groove, so that the threaded sleeve will be limited by the limiting blocks after rotating clockwise or counterclockwise by a certain angle in the threaded sleeve limiting groove. The threaded sleeve is threadedly connected to the connecting screw, and multiple threaded sleeves are axially equidistantly distributed on the connecting screw. The connecting screw is provided with a first thread and a second thread corresponding to the position of the threaded sleeve. The pitch of the first thread is twice the pitch of the second thread, which is used for the variable speed movement of the threaded sleeve.
[0017] Furthermore, a knob is fixedly installed at the rear end of the connecting screw, and a helical column is fixedly installed at the front end of the connecting screw. When the connecting screw rotates, the helical column connects with the threaded groove to fix the screw to the boxing target base.
[0018] Furthermore, the outriggers and the components mounted on them are mirror images of each other at both ends of the counterweight to ensure that the counterweight remains balanced. Attached Figure Description

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0029] Please refer to 1 to 2. Figure 9 As shown, the multifunctional boxing training device provided in this embodiment of the invention includes a boxing target 1, a boxing target base 3, a counterweight unit 4, and a connecting unit 5.
[0030] The punching target 1 is detachably mounted on the punching target frame 2, and multiple targets are provided and symmetrically arranged along the punching target frame 2, allowing the user to hit the punching target 1 from multiple directions.
[0031] The boxing target base 3 is detachably installed at the bottom of the boxing target frame 2. After it is connected to the counterweight unit 4, the weight of the counterweight unit 4 can be added to the boxing target base 3, thereby achieving the function of keeping the entire boxing device balanced.
[0032] The counterweight unit 4 is detachably installed inside the boxing target base 3. The counterweight unit 4 includes multiple counterweight blocks 4.1, and each counterweight block 4.1 has two symmetrically distributed screw channels 4.2.
[0033] The connecting unit 5 includes a connecting screw 5.1 and a threaded groove 5.2. The threaded groove 5.2 is formed on the inner wall of the boxing target base 3. The connecting screw 5.1 passes through the screw channels 4.2 on all the counterweights 4.1 in sequence and then connects to the threaded groove 5.2. There are two connecting screws 5.1. When installing or disassembling, both screws need to be operated at the same time to ensure the stability of the counterweights 4.1. At the same time, there are two threaded grooves 5.2 on the inner wall of the boxing target base 3 corresponding to the two connecting screws 5.1.
[0034] Specifically, the bottom of the counterweight 4.1 is slidably equipped with support legs 6 for supporting the counterweight 4.1, and the support legs 6 are mirror images of the two ends of the counterweight 4.1. Ball bearings 7 are embedded in the bottom of the support legs 6 to allow for smooth movement of the support legs 6 on the ground, reducing inconvenience during installation and disassembly. A reset rod 8 is fixedly installed on the end face of the support leg 6. A sleeve 8.1 is slidably fitted onto the end of the reset rod 8 away from the support leg 6. A reset spring 8.2 is provided between the reset rod 8 and the sleeve 8.1. A reset rod groove 9 is opened on the end face of the counterweight 4.1, and the sleeve 8.1 is slidably disposed within the reset rod groove 9. It should be noted that when the reset spring 8.2 is stretched to its maximum elastic limit, the sleeve 8.1 is still fitted onto the reset rod 8, so the sleeve 8.1 and the reset rod 8 can move up and down together within the reset rod groove 9.
[0035] Furthermore, two locking rods 10 are fixedly installed on the end face of the outrigger 6. The locking rods 10 are both located below the reset rod 8 in the height direction and are distributed vertically. The end face of the counterweight 4.1 is provided with a locking rod groove 11, which is located below the reset rod groove 9. The locking rod 10 can be fully inserted into the locking rod groove 11. When the two locking rods 10 are fully inserted into their respective locking rod grooves 11, the outrigger 6 and the counterweight 4.1 are fixed. When the two locking rods 10 are completely separated from their respective locking rod grooves 11, the outrigger 6 and the counterweight 4.1 are separated.
[0036] Specifically, the support leg 6 is provided with an unlocking unit 12, which is fixedly installed on the side of the support leg 6. The unlocking unit 12 includes an unlocking slider 12.1, an unlocking groove 12.2, and an unlocking spring 12.3. The unlocking slider 12.1 is fixedly installed on the support leg 6 and is slidably disposed in the unlocking groove 12.2, which is located on the side of the counterweight 4.1. An unlocking spring 12.3 is disposed between the end of the unlocking slider 12.1 away from the support leg 6 and the inner wall of the unlocking groove 12.2. The unlocking spring 12.3 is located inside the unlocking groove 12.2. When the unlocking slider 12.1 is squeezed, that is, when the counterweights move closer together, the unlocking spring 12.3 is compressed. When the pressure of squeezing the unlocking slider 12.1 gradually disappears, that is, when the counterweights move away from each other, the unlocking spring 12.3 extends and returns to its original position. The unlocking unit 12 is used to pull the locking rod 10 out of the locking rod groove 11, so that the support leg 6 is separated from the counterweight 4.1.
[0037] Furthermore, a lifting unit 13 is provided on the outrigger 6. The lifting unit 13 is fixedly installed on the side of the outrigger 6 and is located below the unlocking unit 12. The lifting unit 13 includes a lifting slider 13.1, a lifting groove 13.2, and a lifting spring 13.3. The lifting slider 13.1 is fixedly installed on the outrigger 6 and is slidably disposed in the lifting groove 13.2. The lifting groove 13.2 is opened on the side of the counterweight 4.1 and is located below the unlocking groove 12.2. A lifting spring 13.3 is provided between the end of the lifting slider 13.1 away from the outrigger 6 and the inner wall of the lifting groove 13.2. The lifting unit 13 is used to lift the outrigger 6 upward.
[0038] The support leg 6 is positioned at an angle to the unlocking slider 12.1 and the lifting slider 13.1. The surface of the unlocking slider 12.1 near the support leg 6 is a first angled surface 12.4, which is used to displace the support leg 6 after contacting it to unlock it. The surface of the lifting slider 13.1 near the support leg 6 is a second angled surface 13.4, which is used to displace the support leg 6 after contacting it to raise it relative to the counterweight 4.1.
[0039] Furthermore, the counterweight 4.1 is provided with a threaded sleeve limiting groove 14, which is located on the inner wall of the screw channel 4.2. Symmetrical limiting blocks 15 are fixed in the threaded sleeve limiting groove 14, so that when the connecting screw 5.1 rotates, it drives the threaded sleeve 16 to rotate clockwise or counterclockwise within the threaded sleeve limiting groove 14. After a certain angle, the threaded sleeve 16 will be limited by the limiting blocks 15. When the screw is rotated again, the threaded sleeve 16 will begin to move axially in the connecting screw 5.1, that is, it will drive the counterweights 4.1 to move closer to each other. The threaded sleeve 16 is threadedly connected to the connecting screw 5.1. Furthermore, multiple threaded sleeves 16 are axially equidistantly distributed on the connecting screw 5.1. A first thread 5.1.1 and a second thread 5.1.2 are provided on the connecting screw 5.1 corresponding to the positions of the threaded sleeves 16. The pitch of the first thread 5.1.1 is twice the pitch of the second thread 5.1.2. This means that when the connecting screw 5.1 rotates a certain angle, the displacement distance of the threaded sleeve 16 on the first thread 5.1.1 is twice the displacement distance of the threaded sleeve 16 on the second thread 5.1.2. This achieves the tight contact between the equidistantly distributed counterweights 4.1. When the number of counterweights 4.1 is odd, the counterweights 4.1 in the middle position do not need to have threads and threaded sleeves 16 on their corresponding connecting screw 5.1.
[0040] The rear end of the connecting screw 5.1 is fixedly equipped with a knob 5.1.3, which is used to drive the connecting screw 5.1 and the helical column 5.1.4 to rotate during installation or disassembly. The front end of the connecting screw 5.1 is fixedly equipped with a helical column 5.1.4. When the connecting screw 5.1 rotates, the helical column 5.1.4 fixes the screw to the boxing target base 3 by connecting with the threaded groove 5.2.
[0041] It should be noted that the support leg 6 and the components mounted on the support leg 6 are mirror images of the two ends of the counterweight 4.1 so that the counterweight 4.1 remains balanced.
[0042] In addition, the original function of the connecting screw 5.1 is to connect the counterweight unit 4 to the boxing target base 3. However, in the actual implementation process, the connecting screw 5.1 makes the counterweight blocks 4.1 stick together tightly. The sticking of the counterweight blocks 4.1 triggers the unlocking unit 12 and the lifting unit 13. In general, the connecting screw 5.1 can easily add its own weight to the boxing target base 3 during the rotation and installation process.
[0043] During installation, the counterweights 4.1 are placed equidistantly on the ground. The boxing target base 3 is then placed on the counterweights 4.1. The connecting screw 5.1 is then inserted into the side of the boxing target base 3 without the threaded groove 5.2 until the helical post 5.1.4 on the connecting screw 5.1 just enters the threaded groove 5.2. The connecting screw 5.1 connects the counterweights 4.1 and the boxing target base 3. The threaded sleeve 16 is positioned within the threaded sleeve limiting groove 14 in the thickness direction of the counterweights 4.1. At this point, rotating the knob 5.1.3 clockwise limits the threaded sleeve 16 to the threaded sleeve limiting groove 14.
[0044] Furthermore, by continuing to rotate the knob 5.1.3 clockwise, the connecting screw 5.1, under the threaded engagement of the helical column 5.1.4 and the threaded groove 5.2, moves in the direction of the threaded groove 5.2 in the thickness direction of the counterweight 4.1. At this time, the threaded sleeve 16 moves in the thickness direction of the counterweight 4.1 under the threaded engagement of the first thread 5.1.1 and the second thread 5.1.2 of the connecting screw 5.1 with its own thread. Since the threaded sleeve 16 is locked in the threaded sleeve limiting groove 14 of the counterweight 4.1, the counterweight 4.1 moves accordingly in its thickness direction by the rolling of the ball bearings 7 of the support leg 6 on the ground.
[0045] Furthermore, by continuing to rotate the knob 5.1.3 clockwise, the counterweight 4.1 continues to move accordingly in its thickness direction. The unlocking slider 12.1 on the counterweight 4.1 comes into contact with the wall of the adjacent counterweight 4.1 or the unlocking slider 12.1 on the adjacent counterweight 4.1, thereby squeezing and causing the unlocking slider 12.1 to move relative to the counterweight 4.1 in the direction of the inside of the unlocking groove 12.2 along the unlocking groove 12.2.
[0046] In addition, continue to rotate knob 5.1.3 clockwise, and the counterweight 4.1 continues to move accordingly in its thickness direction. The unlocking slider 12.1 moves along the thickness direction of the counterweight 4.1 in the unlocking groove 12.2 towards the inside of the unlocking groove 12.2. At this time, the support leg 6 moves away from the counterweight 4.1 in the length direction of the counterweight 4.1 with the cooperation of the first inclined surface 12.4 of the unlocking slider 12.1. The locking rod 10 moves towards the outside of the locking rod groove 11, so that the support leg 6 and the counterweight 4.1 are unlocked. At this time, the reset rod 8 is stretched along the length direction of the counterweight 4.1.
[0047] Next, continue rotating knob 5.1.3 clockwise. The counterweight 4.1 continues to move, and the unlocking slider 12.1 moves to its maximum distance in the unlocking groove 12.2 along the thickness direction of the counterweight 4.1. The reset rod 8 is stretched to its maximum length. At this time, the locking rod 10 on the support leg 6 disengages from the locking rod groove 11, and the support leg 6 leaves the ground. The counterweight 4.1 is no longer supported by the ground, but its weight is transferred to the boxing target base 3 through the connecting screw 5.1 and is supported by the boxing target base 3. At this time, the lifting slider 13.1 moves to the inside of the lifting groove 13.2 along the thickness direction of the counterweight 4.1. The second inclined surface 13.4 of the lifting slider 13.1 cooperates with the inclined surface of the support leg 6, causing the support leg 6 to gradually move upward. At this time, the reset rod 8 gradually moves upward along the reset rod groove 9 along the height direction of the counterweight 4.1.
[0048] Furthermore, when the knob 5.1.3 is rotated to the maximum angle, the spiral column 5.1.4 is displaced to the farthest distance within the spiral groove, and the counterweight 4.1 moves accordingly to its final position in its thickness direction and is in close contact with each other, and the counterweight 4.1 is additionally displaced by the depth of the thread groove 5.2.
[0049] In addition, when removing the device, turn the knob 5.1.3 counterclockwise, and the screw sleeve 16 will be limited by the screw sleeve limiting groove 14.
[0050] Furthermore, continuing to rotate knob 5.1.3 counterclockwise causes the threaded sleeve 16 to move along the thickness direction of the counterweight 4.1 under the engagement of the first thread 5.1.1 and the second thread 5.1.2 of the connecting screw 5.1 with its own threads. Since the threaded sleeve 16 is locked within the threaded sleeve limiting groove 14, the counterweight 4.1 is displaced along its thickness direction, moving away from each other. At this time, the unlocking slider 12.1 moves outward along the thickness direction of the counterweight 4.1 towards the outside of the unlocking groove 12.2, and the lifting slider 13.1 moves outward along the thickness direction of the counterweight 4.1 towards the outside of the unlocking groove 12.2. The unlocking slider 12.1 then begins to reset under the action of the unlocking spring 12.3, and the lifting slider 13.1 also begins to reset under the action of the lifting spring 13.3.
[0051] Furthermore, by continuing to rotate knob 5.1.3 counterclockwise, the counterweights 4.1 continue to move further apart in the thickness direction. At this time, the reset rod 8 moves to the bottom along the reset rod groove 9 in the height direction of the counterweights 4.1. That is, the support leg 6 moves downward to the bottom in the height direction of the counterweights 4.1, and the ball bearing 7 of the support leg 6 falls to the ground. At this time, the lifting slider 13.1 returns to its initial position.
[0052] Furthermore, continue to rotate knob 5.1.3 counterclockwise, and the unlocking slider 12.1 continues to reset within the unlocking groove 12.2 along the thickness direction of the counterweight 4.1. At this time, the unlocking slider 12.1 just leaves the position between the support leg 6 and the counterweight 4.1. At this time, the reset rod 8 begins to retract, and the support leg 6 moves along the length direction of the counterweight 4.1 in the direction close to the counterweight 4.1.
[0053] Next, continue to rotate knob 5.1.3 counterclockwise until the spiral post 5.1.4 just leaves the threaded groove 5.2. At this time, the unlocking slider 12.1 moves to the initial position within the unlocking groove 12.2, the reset rod 8 retracts to the initial length, and the support moves to the initial position along the length of the counterweight 4.1. At this time, the locking rod 10 enters the locking rod groove 11, the support leg 6 and the counterweight 4.1 are locked, the counterweight 4.1 is supported by the support leg 6, and the counterweight 4.1 moves to the initial position accordingly along the thickness of the counterweight 4.1.
[0054] Next, turn the knob 5.1.3 clockwise so that the connecting screw 5.1 can be pulled out from the screw channel 4.2, remove the boxing target and boxing target frame 2, remove the boxing target base 3, and remove the counterweight 4.1.
[0055] It should be noted that the initial placement of the counterweights 4.1 should be based on an equidistant distribution, with an additional distance from the side of the boxing target base 3 where the threaded groove 5.2 is located. This distance is equal to the depth of the threaded groove 5.2. This is because after the threaded sleeve 16 is limited by the threaded sleeve limiting groove 14, the axial displacement distance of the connecting screw 5.1 within the threaded groove 5.2 is equal to the depth of the threaded groove 5.2. While the connecting screw 5.1 cooperates with the threaded sleeve 16 to make the counterweights 4.1 fit tightly against each other, it will simultaneously drive all the counterweights 4.1 to move to the side of the threaded groove 5.2 by the depth of the threaded groove 5.2.
[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
