Description

Technical Field

[0001] This invention relates to the field of physical fitness assistive training equipment technology, specifically a physical fitness weight training device. Background Technology

[0002] Physical fitness is the ability to adapt to the external environment, mainly including the ability to enjoy activities and adapt to unexpected situations;

[0003] Considering that weight training is an important part of physical training, requiring trainees to complete tasks while bearing weight in order to achieve the training objective, it is necessary to fix the weight to the limbs during weight training. Therefore, some physical weight training equipment with special structures and functions can be used.

[0004] Generally, traditional weight training equipment uses straps or other methods to bind the legs or arms during training to achieve a weight-bearing effect. However, in practical applications, because the weight inside is fixed, multiple weight-bearing devices need to be prepared and used interchangeably. Furthermore, the weight-bearing devices are usually made of fabric, which makes it easy for the fabric and other structures to slip off the limbs, thus affecting the actual training effect. In addition, if a fall occurs during weight training, the impact will cause the weight blocks and other structures to collide with the limbs, which can easily cause injury to the trainee.

[0005] In summary, a physical fitness weight training device is needed to solve the above problems. Summary of the Invention

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.

[0041] Please see Figures 1 to 10 The present invention provides a technical solution:

[0042] A physical fitness weight training device, comprising:

[0043] Connecting cloth block 1, there are several connecting cloth blocks 1, used to connect other components;

[0044] Auxiliary connection structure 2 is disposed between two connecting cloth blocks 1;

[0045] Adjusting counterweight structure 3, the number of adjusting counterweight structure 3 is several, the several adjusting counterweight structure 3 are fixedly connected by connecting cloth block 1, and auxiliary connecting structure 2 seals and fixes the ring state formed by adjusting counterweight structure 3 and connecting cloth block 1.

[0046] Auxiliary protection structure 4 is installed on one side of the adjusting counterweight structure 3 and is used to provide auxiliary protection for the adjusting counterweight structure 3.

[0047] Anti-detachment connection structure 5 is set on top of two auxiliary connection structures 2 and is used to connect and fix two integral parts composed of connecting cloth block 1, auxiliary connection structure 2 and adjusting counterweight structure 3.

[0048] With the auxiliary connecting structure 2, it can work with the connecting cloth block 1 to assist in fixing and connecting the adjustable counterweight structure 3. With the adjustable counterweight structure 3, the counterweight can be increased or decreased according to actual needs, thus eliminating the need to prepare multiple counterweight devices for replacement and making adjustment convenient. At the same time, with the auxiliary protective structure 4, it can buffer the impact force when the trainee falls, thereby avoiding excessive impact force that could cause the counterweight block 34 to injure the body parts. With the anti-detachment connecting structure 5, it can work with components such as the rubber plate 312 to make the connection between the auxiliary connecting structure 2, connecting cloth block 1, adjustable counterweight structure 3 and auxiliary protective structure 4 and the body parts more stable, preventing detachment and thus improving the overall stability and safety.

[0049] refer to Figure 4 The auxiliary connecting structure 2 also includes a first auxiliary cloth block 21 fixedly connected to the connecting cloth block 1 and a second auxiliary cloth block 22 fixedly connected to another connecting cloth block 1. The first auxiliary cloth block 21 and the second auxiliary cloth block 22 are the same size, and the size of the first auxiliary cloth block 21 and the second auxiliary cloth block 22 is smaller than the size of the connecting cloth block 1. The other side of the connecting cloth block 1 fixedly connected to the first auxiliary cloth block 21 and the second auxiliary cloth block 22 is fixedly connected to the auxiliary protective structure 4. A first hook-and-loop fastener 23 is fixedly connected to one side of the outer surface of the first auxiliary cloth block 21.

[0050] By setting the first auxiliary cloth block 21 and the second auxiliary cloth block 22, the adjusting counterweight structure 3 can be assisted in fixing with the connecting cloth block 1, and then assisted in fixing with the first hook and loop fastener 24 and the first hook and loop fastener 23.

[0051] refer to Figure 4 and Figure 5 A first loop fastener 24 is fixedly connected to one side of the outer surface of the second auxiliary fabric block 22 opposite to the first hook-and-loop fastener 23. The first loop fastener 24 and the first hook-and-loop fastener 23 are bonded and fixed together. A first rectangular ring frame 25 is fixedly connected to the end face of the outer surface of the first auxiliary fabric block 21. A third auxiliary fabric block 26 is fixedly connected to one side of the outer surface of the first rectangular ring frame 25. A second loop fastener 27 is fixedly connected to the outer surface of the second auxiliary fabric block 22 opposite to the first loop fastener 24. A second hook-and-loop fastener 28 is fixedly connected to one side of the outer surface of the third auxiliary fabric block 26. The second loop fastener 27 and the second hook-and-loop fastener 28 are bonded and fixed together.

[0052] By setting the first rectangular ring 25, the second auxiliary cloth block 22 can cooperate with the first auxiliary cloth block 21, which in turn can drive the third auxiliary cloth block 26 to cooperate, thereby assisting in fixing the connecting cloth block 1 and other components.

[0053] With the above solution, during the actual use, the second auxiliary cloth block 22 is passed through the inner wall of the first rectangular ring frame 25 during the previous installation, so that the first hook-and-loop fastener 23 and the first loop fastener 24 are fixed together, and the second loop fastener 27 and the second hook-and-loop fastener 28 on the third auxiliary cloth block 26 are fixed together.

[0054] refer to Figure 5 and Figure 6 The adjusting counterweight structure 3 also includes a counterweight frame 31 fixedly connected to one side of the outer surface of the connecting cloth block 1. A rectangular ring frame 33 is fixedly connected to the bottom of the inner wall of the counterweight frame 31. A counterweight block 34 is clamped to the inner wall of the rectangular ring frame 33. A circular locking hole 32 is opened on one side of the inner wall of the counterweight frame 31.

[0055] By setting up a counterweight frame 31, the counterweight block 34 can be assisted in being engaged by the rectangular ring frame 33 inside it, so that the counterweight block 34 can be disassembled and assembled with the counterweight frame 31, thus facilitating the addition or reduction of counterweight.

[0056] refer to Figure 8 A rectangular locking block 35 is snapped into the inner wall of the counterweight frame 31. A circular groove 37 is opened on one side of the inner wall of the rectangular locking block 35. A fixed circular rod 38 is fixedly connected to the inner wall of the circular groove 37. A sliding cylinder 39 is slidably connected to the outer surface of one end of the fixed circular rod 38. The outer surface of the sliding cylinder 39 is detachably snapped into the inner wall of the circular locking hole 32. A first spring 310 is sleeved on the outer surface of the fixed circular rod 38. The two ends of the first spring 310 are fixedly connected to the inner wall of the circular groove 37 and the outer surface of the sliding cylinder 39, respectively.

[0057] By setting a rectangular locking block 35, the rectangular locking block 35 can be assisted in disassembling and fixing to the inner wall of the counterweight frame 31. Under the action of the sliding cylinder 39 and the fixed round rod 38, the rectangular locking block 35 and the counterweight frame 31 can be assisted in fixing together with the round locking hole 32.

[0058] refer to Figure 7 and Figure 8 A rectangular cover block 36 is fixedly connected to the top of the outer surface of the rectangular positioning block 35. A rectangular vertical plate 311 is fixedly connected to one side of the outer surface of the rectangular cover block 36. A rubber plate 312 is fixedly connected to one side of the outer surface of the rectangular vertical plate 311. Several rubber protrusions 313 arranged equidistantly are fixedly connected to one side of the outer surface of the rubber plate 312.

[0059] By setting up a rectangular vertical plate 311 and a rubber plate 312, the rubber plate 312 can fit with the rubber protrusions 313 on its outer surface to adhere to the skin or clothing, thereby preventing the rectangular vertical plate 311 and other components from easily slipping off and separating from the limb.

[0060] With the above structure, during use, the counterweight 34 is placed on the inner wall of the rectangular ring frame 33 inside the counterweight frame 31. At this time, the rectangular locking block 35 is locked into the inner wall of the counterweight frame 31. When the sliding cylinder 39 is aligned with the inner wall of the circular locking hole 32, the sliding cylinder 39 is driven to slide on the outer surface of the fixed rod 38, which in turn causes the first spring 310 to deform, thereby causing the sliding cylinder 39 to lock into the inner wall of the circular locking hole 32. At this time, the rubber plate 312 and rubber protrusion 313 on the rectangular vertical plate 311 are located inside and in contact with the skin or clothing, thereby increasing friction.

[0061] refer to Figure 7 The auxiliary protective structure 4 also includes a rectangular frame 41 fixedly connected to the top of the outer surface of the rectangular cover block 36. A rectangular block 42 is snapped into the inner wall of the rectangular frame 41. First insertion holes 43 are opened on both inner walls of the rectangular frame 41. Second insertion holes 44 are opened on the inner wall of the rectangular block 42. Threaded rods 45 are inserted into the inner walls of the first insertion holes 43 and the second insertion holes 44. A fixing nut 46 is threaded to one end of the threaded rod 45. An L-shaped connecting rod 47 is fixedly connected to the top of the outer surface of the rectangular block 42. A protective plate 48 is fixedly connected to the end of the L-shaped connecting rod 47 away from the rectangular block 42.

[0062] By setting rectangular clip 42 and rectangular clip frame 41, rectangular clip 42 can be clipped into the inner wall of rectangular clip frame 41, and can then be disassembled and assembled with rectangular cover 36. Under the action of threaded insert rod 45, rectangular clip 42 and rectangular clip frame 41 can be disassembled and assembled with assistance, and the protective plate 48 can be disassembled and assembled with assistance, and can then work in conjunction with other components.

[0063] refer to Figure 7 The inner wall of the protective plate 48 is slidably connected with several sliding round rods 49. One end of the outer surface of the sliding round rod 49 is fixedly connected with a round stop 410, and the other end of the outer surface of the sliding round rod 49 is fixedly connected with a rectangular stop 411. A second spring 412 is sleeved on the outer surface of the sliding round rod 49. The two ends of the second spring 412 are fixedly connected to the outer surface of the rectangular stop 411 and the outer surface of the protective plate 48, respectively.

[0064] By setting the sliding rod 49, the sliding rod 49 slides on the inner wall of the protective plate 48, thereby allowing the round block 410 and the rectangular block 411 to limit the sliding rod 49. Under the action of the second spring 412, the sliding rod 49 and other components are provided with auxiliary buffering, thereby avoiding excessive impact force that could cause the counterweight 34 to injure the limbs.

[0065] With the above structure, the rectangular card block 42 is fixed to the rectangular card frame 41, and then the threaded rod 45 is inserted into the inner wall of the first insertion hole 43 and the second insertion hole 44. At this time, the threaded rod 45 is fixed with the fixing nut 46. When an impact occurs, the sliding round rod 49 can slide on the inner wall of the protective plate 48, which can cause the second spring 412 to deform, thereby playing a buffering role.

[0066] refer to Figure 1 and Figure 9 The anti-detachment connection structure 5 also includes a connecting rope 51 whose two ends are respectively fixedly connected to the top of the outer surface of the two first rectangular ring frames 25. The outer surface of the connecting rope 51 is slidably sleeved with a first sliding cylinder 52 at the middle position. A sponge plate 53 is fixedly connected to one side of the outer surface of the first sliding cylinder 52. A number of rectangular anti-slip protrusions 54 are fixedly connected at equal intervals to one side of the outer surface of the sponge plate 53.

[0067] By setting the connecting rope 51, the two auxiliary connecting structures 2 can be used to fix the limbs. At this time, under the action of the first sliding cylinder 52 and the sponge plate 53, the position of the sponge plate 53 can be adjusted, so that it can fit with the rectangular anti-slip protrusion 54 to fit the skin, and avoid the connecting rope 51 from causing marks on the skin.

[0068] refer to Figure 9 and Figure 10 Two second sliding cylinders 55 are symmetrically slidably arranged on both sides of the first sliding cylinder 52 on the outer surface of the connecting rope 51. An elastic strap 56 is fixedly connected between the outer surfaces of the two second sliding cylinders 55. A first strap 57 and a second strap 58 are fixedly connected to the outer surfaces of the two second sliding cylinders 55 opposite to the elastic strap 56, respectively. A circular locking block 59 is fixedly connected to one side of the outer surface of the first strap 57. A second rectangular ring frame 510 is fixedly connected to one side of the outer surface of the second strap 58. A circular locking hole 511 is opened on the inner wall of the second strap 58. The outer surface of the circular locking block 59 and the inner wall of the circular locking hole 511 can be detachably locked together.

[0069] By setting a second sliding cylinder 55, the second sliding cylinder 55 can slide on the outer surface of the connecting rope 51, thereby driving the elastic strap 56 to adjust its position. This allows it to cooperate with the first strap 57 and the second strap 58, enabling the connecting rope 51 to be auxiliaryly fixed to the limb. Under the action of the circular locking block 59 and the circular locking hole 511, it can cooperate with the second rectangular ring frame 510, allowing the second strap 58 to be adjusted in tightness with the first strap 57 for auxiliary fixation. This allows for adjustment for users of different body types, making it convenient to use.

[0070] With the above structure, the connecting rope 51 is passed through the back of the neck, so that the ropes on both sides are in front of the limbs. At this time, the sponge plate 53 can drive the first sliding cylinder 52 to slide on the outer surface of the connecting rope 51, so that the sponge plate 53 and the rectangular anti-slip protrusion 54 can provide auxiliary fixation for the back.

[0071] At this point, the first strap 57 is passed through the inner wall of the second rectangular ring 510 on the second strap 58, so that the circular locking block 59 can be locked into the inner wall of the circular locking hole 511, which can then work with the elastic strap 56 to assist in fixing the body and prevent it from slipping off the limb.

[0072] The overall working principle described above is as follows:

[0073] In use, the counterweight 34 is placed on the inner wall of the rectangular ring frame 33 inside the counterweight frame 31. At this time, the rectangular locking block 35 is locked into the inner wall of the counterweight frame 31. When the sliding cylinder 39 is aligned with the inner wall of the circular locking hole 32, the sliding cylinder 39 is driven to slide on the outer surface of the fixed rod 38, which in turn drives the first spring 310 to deform, thereby causing the sliding cylinder 39 to lock into the inner wall of the circular locking hole 32. At this time, the rubber plate 312 and rubber protrusion 313 on the rectangular vertical plate 311 are located inside and in contact with the skin or clothing, thereby increasing friction.

[0074] During the previous installation, the second auxiliary cloth block 22 was passed through the inner wall of the first rectangular ring frame 25, thereby enabling the first hook-and-loop fastener 23 and the first loop fastener 24 to be fixed together. At the same time, the second loop fastener 27 and the second hook-and-loop fastener 28 on the third auxiliary cloth block 26 were fixed together.

[0075] The rectangular card block 42 is fixed to the rectangular card frame 41, and then the threaded rod 45 is inserted into the inner wall of the first insertion hole 43 and the second insertion hole 44. At this time, the threaded rod 45 is fixed with the fixing nut 46. When an impact occurs, the sliding round rod 49 can slide on the inner wall of the protective plate 48, which can cause the second spring 412 to deform, thereby playing a buffering role.

[0076] At this time, the connecting rope 51 is passed through the back of the neck, so that the ropes on both sides are in front of the limbs. At this time, the sponge plate 53 can drive the first sliding cylinder 52 to slide on the outer surface of the connecting rope 51, so that the sponge plate 53 and the rectangular anti-slip protrusion 54 can provide auxiliary fixation for the back.

[0077] At this point, the first strap 57 is passed through the inner wall of the second rectangular ring 510 on the second strap 58, so that the circular locking block 59 can be locked into the inner wall of the circular locking hole 511, which can then work with the elastic strap 56 to assist in fixing the body and prevent it from slipping off the limb.

[0078] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
