Description

Technical Field

[0001] The utility model relates to the technical field of crutch, in particular to a portable crutch. Background Art

[0002] Orthopedic patients usually refer to patients who have limb diseases or falls that cause mobility problems. After treatment, these orthopedic patients need to use crutches to assist them in walking and recovery.

[0003] Application number CN202120458724.6 discloses an adjustable orthopedic nursing crutch, comprising a main rod and a positioning slot. A gripping handle is fixed to the upper end of the main rod, and an adjustment rod body is provided inside the main rod. The positioning slot is provided at the lower end of the main rod, and a limiting groove is provided on the outer side of the positioning slot. A limiting slide is provided on the outer side of the limiting groove. A limiting protrusion is provided at the lower end of the adjustment rod body, and a base body is provided on the outer side of the limiting protrusion. A positioning shaft is provided on the bottom surface of the adjustment rod body, and a connecting rod is provided at the lower end of the positioning shaft. The lower end of the connecting rod is provided with a limiting rod. The adjustable orthopedic nursing crutch can limit the adjustment rod body through the provided positioning slot, preventing the adjustment rod body from deviating or shaking during use, which would affect its subsequent use. The provided limiting groove can be easily connected to the connecting cover, thereby enhancing the fixing effect of the adjustment rod body.

[0004] However, after the patient's leg is injured, it is inconvenient for the patient to move and the patient needs crutches for support. When the patient's legs are supported by the above-mentioned crutches, there is no support for the patient's legs, and the crutches need to be placed on the hands for support, which makes it inconvenient for the patient's hands to do other work. The crutches are not portable enough, and after the crutches are used for a long time, the buffer device will be worn, resulting in a short service life of the crutches. Utility Model Content

[0005] The utility model discloses a portable crutch, which aims to solve the technical problem that after the crutch is used for a long time, a buffer device is worn out, resulting in a short service life of the crutch and inconvenience in rapid replacement.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A portable crutch comprises a frame, a handle is provided on the top of the frame, a groove is provided on the side wall of the frame, a leg rest is inserted in the groove, a support rod is inserted at the bottom of the frame, a support plate is provided at the bottom of the support rod, and a crutch foot is provided at the bottom of the support plate; a buffer assembly: the buffer assembly is provided at the bottom of the support plate, and the buffer assembly is used to buffer the legs of orthopedic patients on the crutch; a clamping assembly: the clamping assembly is provided on the frame and the leg rest, and the clamping assembly is used to clamp the legs of orthopedic patients on the crutch; the buffer assembly includes a limit plate, which is inserted into the inner wall of the rotating ring, a rotating ring is provided at the top of the crutch foot, and both the crutch foot and the rotating ring are provided with a limiting groove, a fixed plate is provided at the bottom of the support plate, and a first spring is provided between the fixed plate and the limit plate.

[0008] Specifically, when in use, the limit plate is inserted into the cane foot, the limit block passes through the limit slot and is inserted into the cane foot, and the rotating ring is rotated. After the angle of the rotating ring changes, the limit plate cannot be moved out of the cane foot. When the patient walks, the support rod drives the fixed plate, and the first through slot limits the first spring. The limit plate has a damping effect to provide damping to the first spring, so that the crutch has a buffering effect and improves the comfort of the patient. Due to the need to walk for a long time, the first spring is severely worn and needs maintenance and replacement.

[0009] In a preferred embodiment, the clamping assembly includes a clamping plate, a fixing column is inserted into the clamping plate, and a second spring is provided between the fixing column and the clamping plate.

[0010] Furthermore, when in use, the patient's knee is placed in the groove, and the knee pushes the clamping plate, the clamping plate moves under the force, the fixed column moves in the second through groove, and the second spring is deformed under the force, thereby adjusting the position of the clamping plate to limit the patient's knee. After the patient's knee is limited.

[0011] In a preferred embodiment, a limiting block is integrally formed on the outer side of the limiting plate, and the limiting block is inserted into the limiting groove.

[0012] Furthermore, the rotating ring is rotated to make the limiting groove of the rotating ring coincide with the limiting groove of the cane foot, the limiting block is taken out from the limiting groove, and the limiting plate is moved out from the cane foot, so as to facilitate maintenance of the first spring.

[0013] Among them, a first through slot is provided on the limiting plate, and the diameter of the first spring is larger than the diameter of the first through slot; when the patient walks, the support rod drives the fixed plate, the first through slot limits the first spring, and the limiting plate has a damping effect to provide damping to the first spring, so that the crutch has a buffering effect.

[0014] The support rods are provided with threaded holes in a linear array, and the frame body is threadedly connected with bolts, so that the height of the frame body can be adjusted by rotating the bolts.

[0015] Furthermore, a second through slot is provided on the clamping plate, and the diameter of the second through slot is smaller than the diameter of the second spring; the clamping plate moves under force, the fixed column moves in the second through slot, and the second spring deforms under force, thereby adjusting the position of the clamping plate and limiting the patient's knee.

[0016] Wherein, the leg rest is provided with a strap; the strap is used to fix the patient's legs to prevent the patient's legs from swinging back and forth, causing aggravation of bone injuries.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] First: when in use, the patient places the leg in the groove to fix the patient's leg. When the patient uses the crutches, the frame pushes the support rod, and the bottom of the support rod pushes the limit plate. The limit plate cooperates with the first spring to buffer the crutch and improve the patient's comfort. When the buffer assembly is used for a long time, the first spring needs to be maintained or replaced. The rotating ring is turned to facilitate the removal of the limit plate from the crutch foot and the replacement of the first spring.

[0019] Second: The patient's legs are fixed by straps to prevent the patient's legs from swinging back and forth when walking. The grooves are used to place the knees of the legs. Two sets of clamping plates limit the knees of the legs to affect the bone injuries of the legs. BRIEF DESCRIPTION OF THE DRAWINGS
