[0002] As various types of fitness exercises continue to become more popular and the concept of healthy exercise is increasingly accepted by people, various injuries caused by exercise are also attracting more and more attention; at the same time, as the trend of social aging becomes more and more serious, there must be a large number of elderly people in today's society. Due to the inevitable decline of the physical fitness of the elderly, the demand for various relatively mild sports equipment is also increasing; both rehabilitation exercises and low-intensity fitness exercises require some unique fitness equipment, and the upper limb extension compound trainer is a typical equipment among them. Existing upper limb traction exercise equipment is generally a door-type structure with two pull rings suspended. The suspension height is fixed and the suspension distance between the two pull rings is fixed. For users of different heights and people with different arm mobility, the above-mentioned exercise transfer equipment has poor applicability and is not suitable for the above-mentioned rehabilitation exercises. In order to solve the above-mentioned technical problems, the present application document provides a rehabilitation frame for traction upper limb extension. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment one:

[0026] See also Figure 1-5As shown, the utility model is a rehabilitation frame for traction and extension of upper limbs, comprising a base 1. A beam frame 2 is vertically slidably mounted on the base 1. Two synchronous electric cylinders 3 are mounted between the base 1 and the beam frame 2. A hanger 4 is mounted on the upper end of the beam frame 2 for moving in opposite directions. An electric telescopic rod 5 for driving the extension and retraction of the hanger 4 is mounted in the hanger 4. Two lifting ring assemblies 6 are mounted on the hanger 4. A first foot switch 7 for controlling the extension and retraction of the electric cylinder 3 and a second foot switch 8 for controlling the extension and retraction of the electric telescopic rod 5 are mounted on the base 1.

[0027] The base 1 includes a rectangular bottom plate 11. Two cylindrical conduits 12 are fixed at both ends of the upper surface of the rectangular bottom plate 11. The two cylindrical conduits 12 at the same end are connected as a whole by a fixed cross bar 13 to form an H-shaped structure. A mounting plate 14 for mounting the electric cylinder 3 is fixed between the upper ends of the two cylindrical conduits 12 at the same end. The first foot switch 7 and the second foot switch 8 are fixedly mounted on the upper surface of the rectangular bottom plate 11, respectively. The lifting ring assembly 6 includes a first circular ring 61 connected and matched with the circular through hole 424. An elastic rope 62 is tied to the first circular ring 61. The free end of the elastic rope 62 is tied to a second circular ring 63.

[0028] When in use, a person stands on the rectangular bottom plate 11 of the base 1, and the overall frame structure is stable. First, the person controls the electric cylinder 3 to extend or retract by stepping on the first foot switch 7 to place the second ring 63 of the lifting ring assembly 6 at a height that is convenient for the person to reach and pull according to the person's physical condition. Then, the person controls the electric telescopic rod 5 to extend or retract by stepping on the second foot switch 8 to adjust the distance between the two lifting ring assemblies 6 to a width suitable for the person's upper limb exercise and stretching. During the exercise, the person can still adjust the height and relative width of the second ring 63 from the ground according to the exercise rhythm by stepping on the first foot switch 7 or the second foot switch 8.

[0029] Among them, the beam frame 2 specifically includes a rectangular frame 21. A cylindrical rod 22 that slides with a cylindrical guide tube 12 is fixed at the four corners of the lower surface of the rectangular frame 21. Among them, the hanger 4 includes two guide grooves 41 fixed on the top surface of the rectangular frame 21 and two mobile racks 42. The two side walls of the guide groove body 41 are rotatably installed. The two mobile racks 42 are respectively inserted into the guide groove body 41, and the two mobile racks 42 are symmetrically arranged about the shaft gear 43. The mobile rack 42 includes a rectangular rod 421 mounted on the upper end of the rectangular frame 21. A rack 422 that meshes with the shaft gear 43 is fixed to the lower half of both ends of the same side of the rectangular rod 421. A rectangular plate 423 is fixed to the center of one side of the length direction of the rectangular rod 421. Two round through holes 424 are provided on the rectangular plate 423.

[0030] The overall structure of the beam frame 2 and the overall structure of the hanger 4 are reasonable and simple, and the movement of the two lifting ring assemblies 6 and the position fixation when not adjusted are stable and reliable, ensuring the safety of the upper limb traction process. In addition, in order to ensure the safety of the user, a protective belt can be installed on the rectangular frame 21, and the free end of the protective belt is tied around the user's waist when in use to prevent the user from falling when the upper limb slips off the second ring 63.

[0031] In order to enable the hanger 4 to be directional and stable on the beam frame 2, a guide round bar 9 is installed on the upper end of the beam frame 2. A guide sleeve 425 that is slidably matched with the guide round bar 9 is fixed through the two sides of the rectangular rod 421.
