DETAILED DESCRIPTION
[0024] In order to make the technical means, creative features, objectives and functions of the present invention clearer and easier to understand, the present invention is further described below in conjunction with the accompanying drawings and specific implementation methods:
[0025] like Figure 1-4 As shown, this embodiment proposes a weight lifter, including: a frame 1 and at least one set of exercise frames arranged on the frame 1; the exercise frame includes: a first suspension mechanism 21, a lifting rod 22, a second suspension mechanism 23 and a counterweight assembly 24, the first suspension mechanism 21 is installed on the frame 1, the bottom of the first suspension mechanism 21 is connected to the lifting rod 22, the lower end of the lifting rod 22 is provided with a second suspension mechanism 23, at least one set of counterweight assembly 24 is connected below the second suspension mechanism 23, and the first suspension mechanism 21 is configured to be retractable so that the lifting rod 22 can move up and down under the action of an external force. When in use, the exerciser lifts or raises the lifting rod 22 with force to overcome the resistance of the counterweight assembly, at which time the first suspension mechanism 21 contracts, and when the lifting rod 22 is slowly lowered, the first suspension mechanism 21 extends, and this process is repeated to achieve the purpose of exercise.
[0026] The first suspension mechanism 21 includes: a connecting rod 211 and two longitudinal suspension members 212, the connecting rod 211 is installed on the frame 1, the upper ends of the two longitudinal suspension members 212 are respectively connected to the two ends of the connecting rod 211, and the lower ends of the two longitudinal suspension members 212 are respectively connected to the lifting rod 22 and are symmetrically arranged relative to the lifting rod 22; the longitudinal suspension members 212 are arranged to be able to extend and retract up and down; the second suspension mechanism 23 includes at least one counterweight connecting member 231, the upper end of the counterweight connecting member 231 is connected to the lifting rod 22, and the lower end of the counterweight connecting member 231 is connected to a group of counterweight components 24.
[0027] Among them, the structure of the longitudinal suspension member 212 can be designed in various ways, as long as the lifting rod 22 can be lifted and lowered, that is, when the lifting rod 22 is lifted, the longitudinal suspension member 212 contracts upward; when the lifting rod 22 moves downward from the raised state, the longitudinal suspension rod 212 also stretches accordingly.
[0028] Alternatively, if Figure 1-3As shown, the longitudinal suspension member 212 can be a flexible suspension rope 215. This can make the longitudinal suspension member 212 retractable and swingable, so that the lifting rod 22 can move in any direction. It can enable the exerciser to imitate the weightlifting training of carrying water with a shoulder pole, making the training more interesting. At the same time, the longitudinal suspension member 212 is designed as a flexible suspension rope, so that when the exerciser lifts the lifting rod 22 with force, the lifting rod 22 can not only move in the vertical direction, but also can be shaken at various angles such as left and right or front and back in coordination with the lifting action of the human body so that the force applied by the human body in different directions is released, rather than just sticking to the force applied in the vertical direction, which is more suitable for the body extension of the human body in a free state.
[0029] Alternatively, if Figure 4 As shown, the longitudinal suspension member 212 can also be a rigid telescopic rod, which includes a guide cylinder 213 and a guide rod 214. The upper end of the guide rod 214 is movably arranged in the guide cylinder 213, and the lower end of the guide rod 214 is fixedly connected to the lifting rod 22; the top of the guide cylinder 213 is fixedly connected to the connecting rod 211. When the exerciser lifts the lifting rod 22 upward, the guide rod 214 retracts upward into the guide cylinder 213, and the first suspension mechanism 21 contracts. When the lifting rod is moved downward, the guide rod 214 extends downward out of the guide cylinder 213, and the first suspension mechanism 21 extends. This process is repeated to achieve the purpose of exercise. Designing the longitudinal suspension member 212 as a rigid telescopic rod is suitable for strength training only in the vertical direction, and is more suitable for short-distance up and down movement.
[0030] In addition, the counterweight connector 231 mainly plays a connecting role, that is, connecting the counterweight assembly 24 to the bottom of the lifting rod 22. Therefore, the counterweight connector 231 can be designed as a flexible connector or a rigid connector according to specific needs. Preferably, the counterweight connector 231 is designed as a flexible rope structure, and is designed as a flexible suspension rope 215 in conjunction with the longitudinal suspension member 212. In this way, when the exerciser lifts the lifting rod 22 with force, due to the flexible design of the counterweight connector 231 and the longitudinal suspension member 212, the counterweight assembly located below the counterweight connector 231 can shake according to the direction of the exerciser's force, thereby better balancing the overall force.
[0031] The number of counterweight connectors 231 is designed according to customer requirements.
[0032] For example, there may be two weight connection members 231 symmetrically disposed at the two ends of the lifting rod 22; two handles 25 for hand gripping are symmetrically disposed on the lifting rod 22 between the two longitudinal suspension members 212. The exerciser can lift the lifting rod 22 by holding the two handles 25, which can achieve the training effect of weightlifting; the exerciser can also lift the lifting rod 22 by placing the shoulders under the lifting rod 22.
[0033] Alternatively, the weight connection member 231 may be one and disposed in the middle of the lifting rod 22; two handles 25 for hand grasping are symmetrically disposed at both ends of the lifting rod 22; and two longitudinal suspension members 212 are located between the two handles 25. In this way, two exercisers can simultaneously perform weightlifting training in unison, that is, one exerciser holds one handle 25 and the other exerciser holds the other handle 25, and the two people simultaneously lift the lifting rod 22 upward, which increases the interactive fun during exercise.
[0034] In this embodiment, the number of exercise racks can be set to multiple, so that the above-mentioned two designs of weight connectors 231 can be included therein, so as to meet the effect of multiple people exercising at the same time and diversified training. Preferably, there are two exercise racks, namely, a left exercise rack 2 and a right exercise rack 3; the left exercise rack 2 includes two weight connectors 231 and are symmetrically arranged at the two ends of the lifting rod 22; two handles 25 for hand gripping are symmetrically arranged on the lifting rod 22 located between the two longitudinal suspension members 212; the right exercise rack 3 includes a weight connector 231 and is arranged in the middle position of the lifting rod 22; two handles 25 for hand gripping are symmetrically arranged at the two ends of the lifting rod 22; the two longitudinal suspension members 212 are located between the two handles 25. By setting the left exercise rack and the right exercise rack, diversified training can be achieved. The left exercise rack 2 can meet the training of a single person, that is, a single person lifts the lifting rod or a single person lifts the lifting rod with shoulders; the right exercise rack 3 can meet the weightlifting training of two people at the same time. Of course, there are various other training methods, which I will not go into detail here.
[0035] In order to prevent the weight assembly 24 from swinging too much, the bottom of the weight assembly 24 is flexibly connected to the ground, for example, the bottom of the weight assembly 24 is connected to the ground through a chain 26; or the bottom of the weight assembly 24 is connected to the ground through a spring 27. For example, when the spring 27 is used, when the weight assembly swings, the spring 27 can quickly pull the weight assembly back to the initial position, so as to prevent the weight assembly 24 from swinging too much and causing harm to the exerciser.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
