Description

Technical Field

[0001] The utility model designs suspension training equipment, in particular an elastic suspension rod used in suspension training, and belongs to the technical field of machinery. Background Art

[0002] The suspension rod is a training component used to connect the walking trolley above and the patient below in overhead rail training (suspension) training. Usually, the middle part of the upper part of the suspension rod is connected to a switch connected to the hanging sound on the trolley above, with suspension arms on both sides, and the restraint ropes (clothing) for restraining the patient are connected to the suspension arms on both sides. The original suspension rods were all rigid structures, so frequent pulling and releasing of patients during training will make them feel very uncomfortable. In order to overcome this defect, the applicant developed an elastic buffer suspension rod. For example, the buffer suspension rod device on the overhead rail system disclosed in patent application No. 2023219875368 is such a solution. This suspension rod improves the patient experience in actual use and has achieved the expected effect. However, it was found in use that there is room for further upgrading, optimization and improvement of the elastic buffer suspension rod, mainly in that the elasticity of the existing elastic buffer suspension rod is not adjustable, so the elasticity is the same for different patients, especially patients with different weights and patients with different tolerance, and a personalized optimal experience cannot be achieved during training. Summary of the Invention

[0003] The purpose of the utility model is to further optimize the existing elastic buffer suspension rod and provide an elastically adjustable buffer suspension rod for suspension training.

[0004] In order to achieve the purpose of the utility model, the following technical solutions are adopted: an elastically adjustable buffer suspension rod for suspension training, comprising a fixed block located in the middle, a suspension ring rotatably connected to the fixed block, elastic suspension arms are provided on the left and right sides of the fixed block, a connecting ring is fixedly provided on the elastic suspension arm, the elastic suspension arm comprises two springs fixedly connected to the fixed block on the left and right sides of the suspension ring, the outer end of the spring is fixedly connected to an outer sleeve, an elastic adjustment tube is slidably passed through the outer sleeve, the elastic adjustment tube can be extended into the center hole of the spring, a positioning mechanism is provided between the outer sleeve and the inner sleeve, and the connecting ring is fixedly connected to the outer sleeve.

[0005] Furthermore, the two ends of the spring are fixedly connected to the fixed block and the outer sleeve respectively through fixed connecting parts. The fixed connecting parts include an upper fixing part and a lower fixing part. The lower end face of the upper fixing part and the upper end face of the lower fixing part are processed with multiple arc-shaped opening grooves adapted to the spring body. The spring body is located in the arc-shaped opening groove. The upper fixing part and the lower fixing part are fixedly connected by bolts and nuts. A long hole is opened on the elastic adjustment tube, and the bolt passes through the long hole.

[0006] Furthermore, the positioning mechanism is as follows: an indexing pin is fixedly installed on the outer sleeve, a plurality of indexing holes are opened on the elastic adjustment tube along the length direction, and the indexing pin is inserted into one of the indexing holes.

[0007] Furthermore, the positioning mechanism is as follows: a screw hole is processed on the outer sleeve, a top screw is screwed into the screw hole, and the elastic adjustment tube is tightened by the top screw.

[0008] The positive and beneficial technical effect of the utility model is that the buffer suspension rod can not only provide buffering, but also adjust the size of the elasticity, and is more practical for different patients when used in suspension training. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The following will provide a clear and complete description of the technical solutions in the embodiments of the present invention, in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0013] The marks in the accompanying drawings are: 1: fixing block; 2: lifting ring; 3: spring; 4: outer sleeve; 5: elastic adjustment tube; 6: indexing pin; 7: connecting ring; 8: upper fixing piece; 9: lower fixing piece; 10: bolt; 11: arc-shaped opening groove; 12: indexing hole; 13: long hole.

[0014] As shown in the accompanying drawings, an elastically adjustable buffer suspension rod for suspension training includes a fixed block 1 located in the middle, a hanging ring 2 rotatably connected to the fixed block, elastic suspension arms are provided on the left and right sides of the fixed block, a connecting ring 7 is fixedly provided on the elastic suspension arm, and the connecting ring 7 is used to connect the restraint belt. The elastic suspension arm includes two springs 3 fixedly connected to the fixed block on the left and right sides of the hanging ring 2, an outer sleeve 4 is fixedly connected to the outer end of the spring, an elastic adjustment tube 5 is slidably inserted into the outer sleeve, and the elastic adjustment tube can be extended into the center hole of the spring, a positioning mechanism is provided between the outer sleeve and the inner sleeve, and the connecting ring 7 is fixedly connected to the outer sleeve.

[0015] In this embodiment, the two ends of the spring 3 are fixedly connected to the fixed block and the outer sleeve respectively through fixed connecting parts. The fixed connecting parts include an upper fixing part 8 and a lower fixing part 0. The lower end surface of the upper fixing part and the upper end surface of the lower fixing part are processed with multiple arc-shaped opening grooves 11 that are adapted to the spring body. The body of the spring near the end is located in the arc-shaped opening groove 11. The upper fixing part and the lower fixing part are fixedly connected by bolts 10 and nuts. A long hole 12 is opened on the elasticity adjustment tube 5, and the bolt 11 passes through the long hole, so that the elasticity adjustment tube can slide in the outer sleeve to adjust the elasticity.

[0016] In this embodiment, the positioning mechanism is as follows: an indexing pin 6 is fixedly installed on the outer sleeve, and a plurality of indexing holes 12 are opened on the elastic adjustment tube 5 along the length direction. The indexing pin is inserted into one indexing hole. The indexing pin is inserted into different holes. The length of the elastic adjustment tube extending into the spring is different. The longer the length of the elastic adjustment tube extending into the spring, the smaller the elasticity of the suspension rod. Conversely, the greater the elasticity of the suspension rod,
