Description

Technical Field

[0001] The utility model relates to the field of fitness equipment, in particular to a hard shoulder support with adjustable length. Background Art

[0002] The shoulder rest is designed to help patients with upper limb rehabilitation or support the stress on their upper limbs. Existing shoulder rests are generally made of leather or fabric, so the overall material is soft and the support is poor. The fixing strap needs to be passed through a buckle or through-hole to be fixed, which makes it impossible for patients with upper limb dysfunction to put on and take off with one hand. The prior art with patent number CN220824287U discloses a new type of shoulder rest. The patent discloses a shoulder rest with a lifting effect. It is mainly composed of three parts: a shoulder sleeve, a sleeve belt and a waist belt. The connection adopts an ordinary buckle and the length is adjusted in the form of a Japanese buckle. Its overall material is fabric, and the support can be improved; the wearing process requires the nylon strap to be passed through the buckle and then through the Japanese buckle to be fixed, which has the problems of inconvenience in putting on and taking off and inconvenience in adjusting the length. Summary of the Invention

[0003] In response to the above-mentioned problems, the utility model proposes a hard shoulder rest with adjustable length. The design concept is to line the hard shoulder rest with a flexible pad so that the shoulder rest body can be lifted up as a whole by the user with one hand, and then fixed with magnetic buckles on the left and right shoulder straps and the chest strap using an open shoulder strap, so that people with upper limb dysfunction can wear the shoulder rest with one hand and put on and take it off quickly.

[0004] A length-adjustable rigid shoulder rest comprises an upright shoulder rest body 1, one side of the shoulder rest body 1 facing the back of the human body, which is defined as the inner side of the shoulder rest body 1, and the other side of the shoulder rest body 1 is defined as the outer side of the shoulder rest body 1; the shoulder rest body 1 can be disassembled from the middle into a right shoulder rest body 17 and a left shoulder rest body 18;

[0015] To adjust the shoulder rest's lateral length, the user rotates the length adjustment handle 7, which drives the adjustment gear 10, which in turn causes the adjustment rack 9 connected to the left shoulder rest body 18 to move laterally, changing the lateral distance between the right and left shoulder rest bodies 17, 18 to accommodate different patients. The connection between the length adjustment slot 14 and the length adjustment rod 13 ensures that the direction of the displacement of the right and left shoulder rest bodies 17, 18 remains unchanged. The limit block 11 limits the displacement of the right and left shoulder rest bodies 17, 18.

[0016] When taking it off, the user adjusts the length of the chest strap 5 and the shoulder strap 3 through the D-shaped pull ring 4 to loosen the shoulder support body 1 from the user's shoulders, and unfastens the chest strap magnetic buckle 22 and the shoulder strap magnetic buckle 2 in turn, so that the left and right hands can take out the buckles formed by the two shoulder straps 3 and the shoulder support body 1, and finally take off the shoulder support body 1.

[0017] The technical effect of the present invention is that: through the combination of the hard shoulder support body 1, the chest strap magnetic buckle 22 and the shoulder strap magnetic buckle 2, the shoulder support body 1 can be quickly lifted up and worn by the user with one hand, which is convenient for people with upper limb dysfunction to wear the shoulder support with one hand and put on and take it off quickly; at the same time, the distance between the left and right shoulders can be quickly adjusted to adapt to different patients.
