At this time, the infusion rod can be set at the back of the wheelchair body, thereby avoiding affecting the movement of the patient on the wheelchair body.

[0008] The present invention is further configured as follows: the upper end of the infusion pole is further provided with a support pad for supporting the patient's armpit, and the side edge of the storage sleeve is provided with a support leg for cooperating with the support pad to help the patient support on the ground, the end of the support leg is provided with a connecting shaft, and the side edge of the lower end of the storage sleeve is provided with a connecting ear for the connecting shaft to pass through. A connecting hole is provided in the support leg, and a connecting column is provided in the connecting hole, and one end of the connecting column is provided with a threaded end, and the end of the connecting column away from the threaded end is provided with a rubber pad for contacting the ground. The bottom wall of the storage sleeve is provided with a threaded hole for threaded connection of the threaded end, and the end of the hook is hinged on the infusion pole, and an embedding groove for the hook to be embedded and interference fit with the hook is provided on the circumference of the upper end of the infusion pole, and a connecting rope with one end connected to the embedding groove and the other end connected to the hook is provided at the upper end of the infusion pole. An adjustment component for adjusting the height of the infusion pole is also provided in the storage sleeve.

[0009] By adopting the above technical solution, the storage sleeve is removed from the crossbar, and then the support leg is swung downward so that the support leg is in a vertical position, and then the rubber pad and the connecting column are rotated so that the threaded end is threaded into the threaded hole. At this time, the support leg can be stably vertically connected and fixed to the lower side of the storage sleeve, wherein the support pad at the upper end of the infusion pole can be used to support the patient's armpit. At this time, the support pad, infusion pole, storage sleeve and support leg can form a crutch, which is convenient for the patient to perform walking rehabilitation exercises; at the same time, the adjustment component for adjusting the height of the infusion pole is also provided in the storage sleeve. The height of the support pad can be adjusted by using the adjustment component to adapt to the support needs of patients of different heights.

[0010] The present invention is further configured as follows: a slider located in a storage sleeve is provided at the lower end of the infusion pole, a dovetail block is provided on one side of the slider, a vertical rod extending in a vertical direction is provided in the side edge of the storage sleeve, and a dovetail groove is provided in the vertical rod for the dovetail block to be embedded in.

[0011] By adopting the above technical solution, the infusion rod uses the slider at the lower end to be located in the storage sleeve, and the dovetail block of the slider is embedded in the dovetail groove of the vertical rod, which is conducive to the stable up and down movement of the infusion rod in the vertical direction.

[0012] The cam is secured to the side panel that is located adjacent to the two rails and has two locking plates, which are secured to the side panel that is located adjacent to the two rails and have a spring fitted to allow the two rails to move freely.

[0013] By adopting the above technical solution, when the height of the support pad needs to be adjusted, the infusion rod is moved upward, thereby driving the slider and the swing arm to move upward, and the swing arm swings toward the side away from the fixed rack, while the fixed column on the swing arm always contacts the inclined surface of the right-angled triangle head, and the elastic driving arm is compressed until the swing arm passes over a tooth. The elastic restoring force of the elastic driving arm then pushes the swing arm to swing toward the side close to the fixed rack, so that the positioning tooth on the swing arm is embedded in the next tooth. The swing arm swings back and forth in this way when the infusion rod is moved upward, so that the height of the support pad can be conveniently adjusted.

[0014] When the swing arm moves up to the position of the large tooth head, the large tooth head can drive the swing arm to swing so that the fixed column passes over the right-angled triangle head, and then the right-angled triangle head can hook the fixed column, so that the swing arm is positioned at the swing position. When the swing arm moves up and down, it will not come into contact with the fixed rack, and then the infusion pole can be quickly moved down, so that the infusion pole can be quickly moved down and stored in the storage sleeve.

[0015] At the same time, when the swing arm positioned by the right-angled triangle head moves down to the position of the unlocking head, the unlocking head can push the elastic arm upward. Under the action of the elastic restoring force of the elastic driving arm, the hooking state between the right-angled triangle head and the fixed column can be released. Then the positioning teeth of the swing arm can come into contact with the extension rod. Finally, when the swing arm moves up with the infusion rod next time, the positioning teeth can be embedded in the fixed rack again.

[0016] The present invention is further configured as follows: limit arms are provided at both ends of the connecting shaft, a second through hole is provided at the end of the limit arm, a limit column with a spherical end face is provided in the second through hole, a limit plate is provided at the end of the limit column away from the spherical end face, a first return spring is sleeved on the limit column with one end connected to the limit plate and the other end connected to the limit arm, a third through hole is provided on the side wall of the storage sleeve for the limit column to pass through, an inclined portion for abutting against the limit column is provided at the end face of the fixed column, a column located below the unlocking head is provided on the bottom wall of the storage sleeve, and a second return spring is provided between the column and the unlocking head; when the lower end of the swing arm abuts against the bottom wall of the storage sleeve, the inclined portion of the fixed column pushes the limit column to retract into the third through hole.

[0017] By adopting the above technical solution, when the swing arm moves downward and contacts the extension rod, the infusion rod is continuously pressed downward, so that the inclined portion of the fixed column pushes the limit column to retract into the third through hole, and then the supporting leg is pulled outward, the limit column can be disengaged from the third through hole, and then the supporting leg can be swung downward, and finally the downward movement of the infusion rod can be used to unlock the limit state of the supporting leg, so that the supporting leg can be swung downward; wherein, when the wheelchair body is located on a slope and needs to be parked, the support leg that has swung downward can be used to support the slope, thereby assisting parking and preventing the wheelchair body from sliding down the slope.

[0018] The present invention is further configured as follows: a guide fillet is provided on the side of the storage sleeve for the spherical end surface of the limiting column to abut against, and a plurality of hanging slots for hanging articles are provided on the limiting arm.

[0019] By adopting the above technical solution, when the supporting leg is swung downward to a vertical position and used as a crutch, the limiting arm is located at the upper end of the supporting leg. At this time, the hanging groove on the limiting arm can be used to hang the patient's belongings, making it convenient for the patient to carry personal belongings while walking.

[0020] The present invention is further configured as follows: support hooks with an L-shaped cross-section and located on the lower sides of the two cross bars are provided on the side of the storage sleeve, and a locking hook with an L-shaped cross-section and used to be clamped on the upper side of the upper cross bar is provided on the side of the upper end of the storage sleeve.

[0021] By adopting the above technical solution, the storage sleeve can be connected to the crossbar using the support hook and the locking hook.

[0022] The present invention is further configured as follows: vertical holes extending in the vertical direction are provided on both sides of the upper end of the storage sleeve, lifting arms passing through the vertical holes are provided on both sides of the locking hook, a lifting shaft is provided between the two lifting arms and inside the storage sleeve, a lifting block embedded in a dovetail slot is provided in the middle of the lifting shaft, and a third return spring is provided in the dovetail slot with one end fixedly connected to the dovetail slot and the other end fixedly connected to the lifting block.

[0023] By adopting the above technical solution, when it is necessary to remove the storage cover on the cross bar, the lifting arm is moved upward, so that the third return spring is compressed. At this time, the distance between the locking hook and the support hook can be increased until the distance between the locking hook and the support hook is greater than the width of the cross bar, and then the storage cover on the cross bar can be removed.

[0024] The present invention is further configured such that: after the sliding block moves upward, it contacts the lifting shaft.

[0025] By adopting the above technical solution, when it is necessary to remove the storage cover on the cross bar, the operator holds the storage cover with one hand and pulls the infusion rod with the other hand, so that the slider at the lower end of the infusion rod moves up and contacts the lifting shaft. At this time, the upward movement of the infusion rod can help drive the locking hook to move up, so that the distance between the locking hook and the support hook is increased, which ultimately facilitates the more convenient removal of the storage cover on the cross bar.

[0026] The beneficial effects of the present invention are as follows: first, the two cross bars provided on the back of the wheelchair body are utilized, and the storage sleeve can be detachably connected to the cross bars. Then, the first through hole of the storage sleeve can be used for the infusion rod to pass through and be stored. At this time, the infusion rod can be placed at the back of the wheelchair body, thereby avoiding affecting the movement of the patient on the wheelchair body.

[0027] The infusion rod is pulled up to increase the distance between the locking hook and the support hook, thereby quickly removing the storage sleeve from the cross bar, and then the infusion rod is moved down to the limit position, so that the inclined portion of the fixing column pushes the limiting column to retract into the third through hole, and then the supporting leg is pulled outward, and the limiting column can be disengaged from the third through hole, and then the supporting leg can be swung downward, thereby utilizing the downward movement of the infusion rod to unlock the limited state of the supporting leg, and the supporting leg is swung downward so that the supporting leg is in a vertical position, and then the rubber pad and the connecting column are rotated so that the threaded end is threadedly connected in the threaded hole, at this time, the supporting leg can be stably vertically connected and fixed to the lower side of the storage sleeve, wherein the support pad at the upper end of the infusion rod can be used to support the patient's armpit, and at this time the support pad, infusion rod, storage sleeve and supporting leg can form a crutch, thereby facilitating the patient's walking rehabilitation exercise;

[0028] At the same time, an adjustment assembly for adjusting the height of the infusion pole is also provided in the storage sleeve. When the height of the support pad needs to be adjusted, the infusion pole is moved upward, thereby driving the slider and the swing arm to move upward, and the swing arm swings toward the side away from the fixed rack, while the fixed column on the swing arm always contacts the inclined surface of the right-angled triangle head, and the elastic driving arm is compressed until the swing arm passes over a tooth. The elastic restoring force of the elastic driving arm then pushes the swing arm to swing toward the side close to the fixed rack, so that the positioning tooth on the swing arm is embedded in the next tooth. The swing arm swings back and forth like this when the infusion pole is moved upward, so that the height of the support pad can be conveniently adjusted, thereby adapting to the support needs of patients of different heights.

[0029] When the lever is in the unlocking position, the spring will push the lever upwards, and the hooking state between the right-angled triangle head and the fixed column will be released under the action of the elastic restoring force of the elastic driving arm, and the positioning teeth of the lever will come into contact with the extension rod, and finally the positioning teeth can be embedded in the fixed rack again when the lever moves up with the infusion rod next time.

[0030] When the wheelchair body is on a slope and needs to be parked, the swing arm moves downward and contacts the extension rod, and the infusion rod is further pressed downward, so that the inclined portion of the fixing column pushes the limiting column to retract into the third through hole, and then the supporting leg is pulled outward, and the limiting column can be disengaged from the third through hole. Then the supporting leg can be swung downward, and the swung downward supporting leg can be used to support the slope, thereby assisting parking and preventing the wheelchair body from sliding down the slope.
