Description

Technical Field

[0001] The utility model relates to rehabilitation training equipment, in particular to a simple adjustable resistance balance trainer, belonging to the technical field of rehabilitation training machinery. Background Art

[0002] Balance trainers are used in rehabilitation training on various occasions, such as joint surgery, sports injuries, and field training injuries. In order to meet the training needs of different patients, many balance trainers generally have resistance and the resistance is adjustable. The resistance of common balance trainers with resistance generally adopts hydraulic dampers, electric cylinders, etc. For example, a dynamic balance training device disclosed in Chinese Patent CN108744431B uses four dampers, and a balance training system disclosed in CN108704246B also uses four hydraulic dampers. Although the above devices can achieve dynamic balance training and adjustable resistance, due to the large weight and high cost of the resistance devices used, the overall equipment is overweight, the mobility is poor, and the price is relatively high. In addition, it also needs to rely on power supply. For some occasions, such as military training and field training, the above devices are not applicable. Summary of the Invention

[0003] The purpose of the utility model is to provide a simple adjustable resistance balance trainer with a simple structure, no power required, and easy to transfer and carry.

A column is fixedly connected to the center of the base. The lower end of a cross-axis universal joint is fixedly connected to the column, and the upper end is fixedly connected to the center of a support plate. A foot pedal is fixedly connected to the support plate. Four resistance adjustment boxes are fixedly connected to the base. The four resistance adjustment boxes are located on the same circumference and are evenly distributed. Each resistance adjustment box includes a box body, on which a screw rod is rotatably connected. A threaded sleeve is screwed on the screw rod. A lower ring is fixedly connected to the threaded sleeve. An upper ring is fixedly connected to the bottom surface of the support plate.

Both the upper limit block and the lower limit block are annular blocks, and the cross-axis is located in the holes of the annular blocks.

[0006] Further, the screw rod is along the radial direction of the base.

[0007] Further, two eye bolts are fixedly connected to the base at an interval of 180 degrees, and the eye bolts are used to connect elastic ropes.

[0008] Further, a scale is provided on the box body along the direction of the screw rod.

[0009] Further, elongated guide holes are provided on two side surfaces of the box body, and trunnions are fixedly connected to both sides of the nut, and the trunnions are located in the guide holes.

[0013] To more fully explain the implementation of the present utility model, implementation examples of the present utility model are provided. These implementation examples are only an elaboration of the present utility model and do not limit the scope of the present utility model.

[0014] The present utility model is further explained in detail with reference to the accompanying drawings. The reference numerals in the drawings are: 1: base; 2: adjustable feet; 3: column; 4: cross-axis universal joint; 5: support plate; 6: foot pedal; 7: adjustment box; 8: upper ring; 9: lower limit block; 10: upper limit block; 11: spring; 12: protective cover; 13: eye bolt; 701: box body; 702: screw rod; 703: threaded sleeve; 704: lower ring; 705: trunnion; 706: guide hole.

[0015] As shown in the accompanying drawings, a simple type adjustable resistance balance trainer includes a base 1. Two eye bolts are fixedly connected to the base at an interval of 180 degrees. The eye bolts are used to connect elastic ropes, and during training, the elastic ropes can be held by hand to enhance the safety of training. A plurality of adjustable feet 2 are installed under the base. A column 3 is fixedly connected to the center of the base. The lower end of the cross-axis universal joint 4 is fixedly connected to the column, and the upper end is fixedly connected to the center of the support plate 5. A foot pedal 6 is fixedly connected to the support plate. An upper limit block 10 is fixedly connected to the lower end surface of the support plate, and a lower limit block 9 is fixedly connected to the upper part of the column. Both the upper limit block and the lower limit block are annular blocks, and the cross-axis is located in the holes of the annular blocks. During dynamic balance training, the upper limit block and the lower limit block interfere with each other to limit the movement amplitude.

[0016] Four resistance adjustment boxes 7 are fixedly connected to the base. The four resistance adjustment boxes are located on the same circumference and are evenly distributed. The resistance adjustment box includes a box body 701. A screw rod 702 is rotatably connected to the box body. The screw rod can only rotate and does not have relative displacement in the axial direction with the box body. The screw rod 702 is along the radial direction of the base. A scale is arranged on the box body 701 along the direction of the screw rod. The scale can correspond to the tensile force of the spring. A threaded sleeve 703 is screwed onto the screw rod. The threaded sleeve is an internal threaded sleeve. Longitudinal guide holes 706 are opened on two sides of the box body. The length direction of the longitudinal guide holes is parallel to the screw rod. Ears 705 are fixedly connected to both sides of the threaded sleeve. The ears are located in the guide holes. In this way, when adjusting, the threaded sleeve can only move along the length direction of the guide hole. A lower ring 704 is fixedly connected to the threaded sleeve. An upper ring 8 is fixedly connected to the bottom surface of the support plate. The two ends of the spring are respectively hung on the upper ring and the lower ring. Figure 1 In the figure, the upper end of the spring is suspended only for illustration. The upper end of the spring is hung on the upper ring. The screw rod has a wrench clamping portion. The wrench is used to drive the screw rod to rotate.

[0017] When this balance trainer is in use, when the foot pedal tilts, it stretches the spring, and the spring stretching generates resistance. Rotating the screw rod can adjust the position of the threaded sleeve so as to adjust the tensile force of the spring. In this balance trainer, the threaded sleeves on the four resistance adjustment boxes can be adjusted to the same scale. At this time, the four springs generate the same resistance during training. The threaded sleeves on the four resistance adjustment boxes can also be adjusted to different scales. At this time, the four springs generate different resistances during training, and the training difficulty is higher.

[0018] After the embodiments of the present invention are described in detail, those skilled in the art can clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent application. Any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention all belong to the scope of the technical solution of the present invention, and the present invention is not limited to the embodiments described in the specification either.
