Description

Technical Field

[0001] The utility model belongs to the technical field of fitness equipment, and particularly relates to a large counterweight lower limb trainer. Background Art

[0002] Among the existing sports training equipment, most of the training equipment for the lower limbs is of a backrest design. When in use, the trainer squats with his back against the equipment, and a counterweight structure similar to an Olympic bar is provided on the equipment. The trainer and the assistant cooperate to achieve the squat training of carrying heavy objects on the back. However, the disadvantage of this kind of equipment is that it requires two people to operate, and there is a certain safety risk during training.

[0003] Developers in this field have designed a lower limb trainer for neck traction or shoulder traction. When in use, this kind of equipment can use the middle swing rod as an auxiliary support, and heavy objects are suspended on the counterweight rods on both sides. The trainer realizes the training of the lower limb muscle groups by driving the counterweight up and down to squat. During the training process, it can be completed by a single person. If an emergency occurs, the counterweight rod can be supported by the support part on the middle swing rod to prevent waist or lower limb injuries caused by the instantaneous drop of the counterweight rod.

[0004] However, when this kind of training equipment is in use, according to the feedback of users, it still has disadvantages, specifically manifested as follows: 1. When realizing large counterweight training, the distance between the counterweight rods on both sides is relatively narrow, and when vertically stressed and swinging, the overall performance of the training equipment is insufficient in rigidity; 2. The hand force application point is designed as a curved handle structure, which is not conducive to the outward pushing force of the arm, and it is impossible to achieve stable force application of the palm and the arm during the training process; 3. The existing middle swing rod is provided with a front swing limit device, and its restraint on the front swing amplitude of the middle swing rod is very small, resulting in a reduced squatting amplitude of the trainer.

[0005] In view of the disadvantages of the existing technology and the current actual needs of trainers, as a person skilled in the art, how to design an improved version of the large counterweight lower limb trainer through technical improvement is a technical problem that needs to be solved urgently by the person skilled in the art.

[0024] The following further describes the present utility model through specific embodiments. It should be understood that the following description is a specific implementation scheme based on the technical solution disclosed by the present utility model, and those skilled in the art can make further technical extensions based on the disclosure of the following technical solutions.

[0025] Referring to the drawings, a large counterweight lower limb trainer disclosed by the present utility model, as shown in the drawings, includes a chassis 1. Support bases 15 are respectively arranged at the four corners of the bottom of the chassis 1, and the horizontal support of the chassis 1 is realized through the support bases 15; a pedal 14 is arranged on the top surface of the rear end of the chassis 1, where it can be used for the trainer to stand.

[0026] There are a front articulated column 2, a middle articulated column 11 and a terminal support column 12 arranged on the upper part of the chassis 1. Inside the front articulated column 2, a counterweight frame 3 is articulated through a counterweight frame bearing seat 21 as a rotating shaft assembly. The counterweight frame 3 includes two side counterweight rods 32 symmetrically arranged left and right and a middle force application rod 33. The side counterweight rods 32 are designed for reinforcement, including a front articulated section 321, a middle outward expansion section 322 and a terminal counterweight section 323. The width of the front articulated section 321 is relatively narrow, which is used to articulate with the front articulated column 2. Through an S-shaped bending, the whole end of the counterweight frame 3 expands outward to obtain reinforcement, improving the overall strength of the side counterweight rod 32 and increasing the bearing capacity on the side of the suspended counterweight. A suspension rod 35 is arranged outside the terminal counterweight section 323, and a larger number of counterweight plates are suspended and supported through the suspension rod 35.

[0027] To further improve the overall strength of the counterweight frame 3, a front articulated rod 31 and a middle support positioning rod 34 are arranged through the side counterweight rod 32 and the middle force application rod 33; a rear suspension pulling part 36 is arranged at the rear end of the middle force application rod 33; when the utility model is in use, a fixing hole or a hook is arranged on the pulling part 36, and a trainer can hook a pulling belt through the neck or the shoulder, and the pulling belt is hooked on the pulling part 36 to realize the vertical pulling of the whole counterweight frame 3.

[0028] A middle swing frame 4 is articulated and arranged on the middle articulated column 11 through a swing frame bearing seat 45. The middle swing frame 3 includes two articulated columns 40 symmetrically arranged left and right. A bottom reinforcement rod 11 is arranged at the lower half of the articulated column 40, and an auxiliary connecting rod 43 is arranged at the upper half of the articulated column 40. The auxiliary connecting rod 43 penetrates and connects the symmetrically arranged articulated columns 40 left and right. A fixing plate 41 is arranged on the front side of the middle swing frame 4, and a plurality of through holes are vertically machined on the fixing plate 41. The vertical support seat 45 can be fixed and the vertical height can be adjusted through the through holes. The vertical support seat 45 cooperates with the middle support positioning rod 34. When the middle support positioning rod 34 falls into the vertical support seat 45, support and fixation are realized. When doing a squat training, the middle support positioning rod 34 disengages from the vertical support seat 45.

[0029] Two horizontal force application handles 42 are symmetrically arranged on the inner side of the top of the middle swing frame 4; through this kind of structural arrangement, a trainer can grasp the horizontal force application handles 42 in a diving state, and it is easier to exert force in this state and the force application safety is high. Further, the horizontal force application handles 42 are arranged above the auxiliary connecting rod 43. Since the auxiliary connecting rod 43 is also horizontally arranged and is arranged up and down with the horizontal force application handles 42, when a user operates, the force application position can be adjusted up and down.

The two front swing limit piles 16 are all arranged close to the hinge column 40, and this structure can prevent the excessive forward swing of the middle swing frame 4 from affecting the downward swing of the counterweight frame 3.

[0031] The end support column 12 is arranged at the top of the rear end of the chassis 1, and a rubber buffer block is arranged at the top of the end support column. The end support column 12 is arranged directly below the side counterweight rod 32 for protective support. When a trainer is performing a squat training, if due to an operation error or physical exhaustion, the trainer cannot bear a large counterweight, the side counterweight rod 32 bears the falling impact and provides support at a certain height, and the rubber buffer block realizes gravity buffering to avoid harm to the human body.

[0032] A front counterweight placement rod 22 is arranged outside the front hinge column 4, which is used for storing counterweight plates and front counterweight. The purpose of the front counterweight here is to improve the stability of the entire large counterweight lower limb trainer.

[0033] To improve the stability of the front counterweight placement rod 22 and the suspension rod 35 after hanging the counterweight, protective clips 23 are arranged on both the front counterweight placement rod 22 and the suspension rod 35. At the same time, both the front counterweight placement rod 22 and the suspension rod 35 are arranged obliquely upward. This design can prevent the counterweight plates from falling and improve the safety when using this equipment.

[0034] When the public embodiment is disclosed, it should also be noted that the above are only the embodiments and beneficial effects of the utility model. It should be pointed out that for those of ordinary skill in the field of fitness equipment technology, without departing from the principle of the utility model, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the utility model.
