Description

Technical Field

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

[0002] For patients with lower limb fractures, in order to facilitate their daily walking activities, axillary crutches are their best choice. When in use, the axillary crutches are placed under the armpit of the affected limb to assist in walking. However, in order to facilitate walking on complex roads, the lower ends of existing axillary crutches are thinner, which leads to poor stability. Especially when patients need to stand up after sitting down to rest, the axillary crutches cannot provide stable support. Patients need to rely on other objects or other people to help them stand up first, and then use the axillary crutches, but this reduces the practicality of the axillary crutches. At the same time, when patients sit down to rest, it is difficult to place their legs, and they are prone to problems such as contact with the ground or long-term fatigue. In addition, when patients sit down, the axillary crutches need to be tilted or placed horizontally, which takes up a large space, affects the movement of other people, and is also very inconvenient to take when in use. Utility Model Content

[0013] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0014] Depend on Figures 1 to 7 It is given, including a turning body 1, a supporting column 2 with an upper and lower axial direction is fixed to the lower end of the turning body 1, a chassis 3 is coaxially fixed to the lower end of the supporting column 2, the diameter of the chassis 3 is larger than the diameter of the supporting column 2, and a plurality of grooves evenly distributed along its circumferential direction are opened on the chassis 3, an expansion disk 4 that can move inward and outward is provided in the groove, and a plurality of expansion disks 4 and the chassis 3 can form a circle, a slip ring 5 that can move up and down is coaxially provided on the supporting column 2, the upper end of the expansion disk 4 is hingedly connected to the slip ring 5 through a connecting rod 6, the distance between the upper ends of the plurality of connecting rods 6 is smaller than the distance between their lower ends, and a plurality of leg plates 7 distributed along the upper and lower directions and that can swing back and forth are provided at the front end of the supporting column 2.

[0015] In order to enable the expansion disk 4 to move inward and outward, a T-shaped fixing rod 8 is fixed on the inner side wall of the groove, and a T-shaped connecting sleeve 9 is slidably connected to the fixing rod 8. The connecting sleeve 9 is inserted into its corresponding expansion disk 4 and is slidably connected to the expansion disk 4.

[0016] In order to enable the slip ring 5 to move up and down, a sliding column 10 is slidably connected to the support column 2 in the left and right axial directions and located above the slip ring 5. The lower end of the sliding column 10 is fixedly connected to the slip ring 5 via a push rod 11.

[0017] In order to limit the position of the sliding column 10, the right end of the sliding column 10 extends out of the support column 2 and is coaxially slidably connected to a control sleeve 12 with a T-shaped axial cross-section. The right end of the sliding column 10 is connected to the control sleeve 12 via a tension spring. The right end of the support column 2 is provided with two limit grooves 13 distributed up and down and opening to the right. The left end of the control sleeve 12 can be inserted into the limit groove 13.

[0018] In order to allow the leg board 7 to swing back and forth, the front end of the support column 2 is provided with a plurality of makeshift grooves corresponding to the leg board 7 one by one. The leg board 7 is located in the makeshift groove and its lower end is rotatably connected to the support column 2. The leg board 7 can contact the lower side wall of the makeshift groove. The rear end of the leg board 7 is fixedly connected to the support column 2 via an elastic band 14. An auxiliary rod 15 is slidably connected in the support column 2 in the up and down directions. The front end of the auxiliary rod 15 is fixed with a plurality of push blocks 16 corresponding to the leg board 7 one by one and the front end is inserted into the makeshift groove. The front end of the push block 16 can contact the leg board 7. The upper end surface of the auxiliary rod 15 is an inclined surface with a high front and a low back. The sliding column 10 can contact the inclined surface of the auxiliary rod 15.

[0019] In order to increase friction, friction pads 17 having the same shape as their lower end surfaces are fixed to the lower ends of the chassis 3 and the expansion plate 4 respectively.

[0020] When the utility model is in use, the initial state is that the sliding column 10 is located above the auxiliary rod 15, the control sleeve 12 is inserted into the upper limit groove 13, the leg plate 7 does not extend out of the clearance groove and is in the up and down direction, and the multiple expansion plates 4 and the chassis 3 form a cylindrical shape. At this time, it can be used as a normal axillary crutch.

[0021] When the patient sits down to rest and needs to place the crutch 1 and support the legs, the control sleeve 12 is pulled to the right, and the control sleeve 12 moves out of the upper limit groove 13, releasing the limit on the slide column 10, and moving the control sleeve 12 downward. The control sleeve 12 drives the slide column 10 to move downward, and the slide column 10 drives the slip ring 5 to move downward through the push rod 11, and the slip ring 5 drives the upper end of the connecting rod 6 to move downward. Since the distance between the upper ends of multiple connecting rods 6 is smaller than the distance between their lower ends, the lower end of the connecting rod 6 will push the expansion plate 4 outward, and the expansion plate 4 moves horizontally outward under the action of the fixing rod 8 and the connecting sleeve 9.

[0022] When the sliding column 10 pushes the movement of the connecting rod 6, the sliding column 10 approaches and contacts the inclined surface of the auxiliary rod 15. The auxiliary rod 15 moves forward under the push of the sliding column 10, and the push block 16 moves forward synchronously and pushes its corresponding leg plate 7 to swing forward. The elastic belt 14 is stretched by the force. After the sliding column 10 moves downward a certain distance, the sliding column 10 breaks away from the contact with the inclined surface of the auxiliary rod 15 and contacts the vertical rear end surface of the auxiliary rod 15. At this time, the upper end of the leg plate 7 extends out of the clearance groove.

[0023] When the control sleeve 12 moves to be opposite to the limit groove 13 on the lower side, the control sleeve 12 is released. The control sleeve 12 moves to the left under the action of the tension spring and is inserted into the limit groove 13 on the lower side. At this time, under the action of the structure formed by the expansion plate 4, the connecting sleeve 9, and the fixing rod 8, which is similar to the action of the three-section telescopic rod, the expansion plate 4 moves outward a longer distance, thereby increasing the space occupied by multiple expansion plates 4, and then the expansion plate 4 and the chassis 3 can stably support the support column 2 and the crutch 1, so that the support column 2 and the crutch 1 remain in a vertical state in the up and down directions, reducing the space occupied. At this time, the patient can manually bend the leg board 7 of the appropriate height downward as needed, so that the leg board 7 contacts the lower side wall of the clearance groove. At this time, the leg board 7 is in a horizontal direction, and the affected limb can be placed on the leg board 7 for support.

[0024] When it is necessary to stand up, since the expanded disc 4 is in a state of wide support at this time, the patient can stand up by holding the crutch 1 without the help of others, which is more convenient. After the patient stands up, the control sleeve 12 can be pulled to the right to move the control sleeve 12 out of the lower limit groove 13, and then the control sleeve 12 is moved upward to move the slide column 10 upward, and the expanded disc 4 moves inward to restore the initial position. The slide column 10 moves again to above the auxiliary rod 15, and the leg plate 7 is changed to a vertical state in the up and down directions again under the action of the elastic band 14, so that the control sleeve 12 can be inserted into the upper limit groove 13 again for normal use.

[0025] The utility model has the advantages of simple structure, convenient operation, novel concept and strong practicality. The sliding ring, connecting rod and expanding plate are used to increase the range of support of the supporting column by the expanding plate and the chassis, thereby increasing the stability of the supporting column. At the same time, the fixing rod, connecting sleeve and the sliding connection between the connecting sleeve and the expanding plate ensure that the expanding plate moves in the horizontal direction, and it is convenient for the expanding plate to move outward to the farthest distance, thereby achieving more stable support for the supporting column and the turning body, thereby ensuring that the turning body can be stored in a vertical state without tipping or horizontal placement. Moreover, through the arrangement of the sliding column, auxiliary rod, push block, elastic band and leg board, when the sliding column drives the sliding ring to move downward through the push rod, the upper end of the leg board is pushed out of the yield groove, thereby facilitating the placement and support of the patient's legs. Moreover, the upper end of the leg board is pushed out of the yield groove, which makes it convenient to swing the leg board to a horizontal state for placing the legs and also prevents other unused leg boards from affecting the placement of the legs, thereby making it more convenient to use.
