Description

Technical Field

[0001] The utility model relates to the technical field of arm exercise equipment, in particular to an adjustable arm exercise equipment. Background Art

[0002] As we all know, rehabilitation equipment is mainly used to help patients carry out passive exercises and daily activities and promote recovery. In order to speed up limb rehabilitation, it is necessary to lift the arms for exercise and improve flexibility, so arm exercise equipment is needed.

[0003] However, existing handle exercise equipment is mostly a simple double-lever structure, which can only be driven in two directions for operation. The height of the equipment cannot be adjusted to meet the needs of patients of different heights, and the adaptability is poor. Therefore, an adjustable arm exercise equipment is proposed.

[0004] Publication No. CN221181560U discloses an adjustable arm exerciser. The adjustable arm exerciser comprises a main body, a fixed base fixed to the main body, a seat mounted on the base, a heating plate mounted within the seat, a heating wire mounted within the heating plate, a cooling fan mounted at one end of the heating plate, a front push assembly mounted on the main body, and a longitudinal push assembly mounted on the back of the main body. The arm exerciser provided with this device has the front push assembly and the longitudinal push assembly mounted on the main body to exercise the user's arms, thereby facilitating rapid recovery. The user can push the arm up and down to achieve exercise in different directions. The main body of the arm exerciser adopts a chair-style design for arm exercise, which is suitable for different groups of people and expands the device's applicability. The seat cushion mounted on the main body is equipped with a heating wire and a cooling fan to ensure user comfort in different weather conditions.

[0005] Although the above patent has achieved the goal of installing a front pushing component and a longitudinal pushing component on the main body of the arm exercise equipment to exercise the user's arms, thereby helping to recover quickly, and allowing the user to push up and down to achieve exercise in different directions, the main body of the arm exercise equipment adopts a chair-type for arm exercise, which is suitable for different people and improves the applicability of the device. The seat cushion installed on the main body is respectively equipped with electric heating wire and cooling fan to ensure the comfort of users in different weather; however, the device lacks a structure for fixing and supporting the waist. By setting a support and fixation for the waist, the potential injury caused by incorrect posture can be effectively reduced, which is particularly important in high-intensity or repetitive motion exercises.

[0006] Therefore, it is necessary to invent an adjustable arm exercise device to solve the above problems. Utility Model Content
