A walking assistance nursing device

Abstract

The present invention discloses an auxiliary walking nursing device, and relates to the technical field of auxiliary walking devices. The present invention comprises a base frame, and a front universal wheel and a rear universal wheel are arranged at the bottom of the base frame. There are two front universal wheels in total, and a connecting shaft is fixedly installed between the rotating shafts of the two front universal wheels, and a first gear is fixedly installed on the connecting shaft, and the first gear is connected to the second gear through a gear belt transmission, and the second gear is rotatably installed on a disc, and the disc is rotatably installed on a fixed shaft, and a control mechanism is arranged on the fixed shaft. The present invention drives the pawl to move downward through a micro hydraulic cylinder, so that the pawl cooperates with the ratchet wheel. When the vehicle slips on the uphill slope, the front universal wheel rotates, driving the ratchet wheel to rotate. Since the pawl is clamped on the ratchet wheel, the ratchet wheel cannot rotate, and the front universal wheel will also be unable to rotate. When the patient goes uphill, the front universal wheel can only rotate in one direction, thereby avoiding the situation of slipping, and ensuring the safety of the patient.

Description

Technical Field

[0001] The present invention belongs to the technical field of auxiliary walking devices, and in particular, relates to an auxiliary walking nursing device. Background Art

[0002] Neurosurgery is a branch of surgery. It uses unique neurosurgery research methods to study the human nervous system, such as the brain, spinal cord and peripheral nervous system, and its related ancillary structures, such as the skull, scalp, cerebral blood vessels and meninges, for damage, inflammation, tumors, malformations and certain genetic metabolic disorders or functional disorders. When the patient's body is affected by the relevant nerves, symptoms of mobility problems may occur. At this time, the patient needs to use assisted walking care devices for medical rehabilitation.

[0003] However, when the current auxiliary walking device is used, when encountering an uphill slope, it is easy to slip after going uphill due to the lack of a protective mechanism, which can easily cause injuries to the user. In view of the above problems, the inventor proposes an auxiliary walking care device to solve the above problems. Summary of the invention

[0004] In view of the problems in the related art, the present invention proposes an auxiliary walking care device to overcome the above-mentioned technical problems existing in the existing related art.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] Furthermore, the control mechanism includes a moving block arranged on a fixed shaft, the moving block is fixedly mounted with an output shaft of a micro hydraulic cylinder, the micro hydraulic cylinder is fixedly mounted inside the base frame, the fixed shaft passes through the moving block, the moving block is fixedly mounted on the fixed shaft, the disc is provided with a slide groove, and the fixed shaft is slidably connected inside the slide groove.

[0008] Furthermore, the connecting shaft is rotatably mounted inside the protective shell, the protective shell is fixedly mounted on the bottom of the base frame, the base frame is hinged with a seat cushion, a support column is fixedly mounted above the base frame, and the support column is slidably connected with a telescopic column.

[0009] Furthermore, the support column is provided with a first threaded hole, and the telescopic column is provided with a second threaded hole, the first threaded hole is adapted to the second threaded hole, the first threaded hole and the second threaded hole are threadedly connected with a nut, and the nut is used to fix the support column and the telescopic column, and an arc-shaped support plate is fixedly installed above the telescopic column.

[0010] Furthermore, there are two rear universal wheels in total, the rotating shaft of the rear universal wheel is fixedly installed with a connecting roller, the connecting roller is fixedly installed with a cam, the base frame is slidably connected with a moving rod, the moving rod is fixedly installed with an arc-shaped speed reducer, and the arc-shaped speed reducer corresponds to and cooperates with the cam.

[0011] Furthermore, there are two movable rods and two arc-shaped speed reducers in total, and the two movable rods are threadedly connected with a bidirectional screw rod, one end of the bidirectional screw rod is fixedly mounted with the output shaft of the driving motor, and the other end is rotatably mounted inside the base frame, and a sliding groove is opened at the bottom of the base frame, and the two movable rods are slidably connected inside the sliding groove.

[0013] Furthermore, the front universal wheel and the rear universal wheel are both provided with brake baffles.

[0014] The present invention has the following beneficial effects:

[0015] 1. The present invention drives the pawl to move downward through a micro hydraulic cylinder, so that the pawl cooperates with the ratchet. Therefore, when the vehicle slips on an uphill slope, the front universal wheel rotates clockwise, driving the ratchet to rotate clockwise. Since the pawl is clamped on the ratchet and the pawl is limited by the fixed block, the ratchet cannot rotate clockwise, and the front universal wheel cannot rotate clockwise. Therefore, when the patient goes uphill, the front universal wheel can only rotate in one direction, thereby avoiding the vehicle slipping and ensuring the safety of the patient.

[0016] 2. The present invention makes the first threaded hole and the second threaded hole fit together, and then uses a nut to penetrate the first threaded hole and the second threaded hole to make them threadedly connected and fixed, so that the telescopic column is used to drive the arc support plate to move up and down, so that patients of different heights can place their armpits on the arc support plate for auxiliary support, thereby enhancing practicality.

[0017] 3. The present invention drives the bidirectional screw to rotate through the second button, so that the two moving rods move toward the central axis position of the bidirectional screw at the same time, and then drives the two arc-shaped deceleration plates to move toward the cam. Through the mutual cooperation of the arc-shaped deceleration plates and the cam clamping, the rotation of the connecting roller is decelerated and limited, and then the movement of the rear universal wheel when going downhill can be decelerated and limited to avoid the patient being knocked down due to excessive downhill speed, thereby enhancing safety. When the patient does not need to move, he only needs to step on the brake baffle to lock the front universal wheel and the rear universal wheel.

[0018] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] See also Figure 1-8 As shown, the present invention is an auxiliary walking care device, including a base frame, a front universal wheel and a rear universal wheel are arranged at the bottom of the base frame, there are two front universal wheels, a connecting shaft is fixedly installed between the rotating shafts of the two front universal wheels, a first gear is fixedly installed on the connecting shaft, the first gear is connected to the second gear through a gear belt transmission, the second gear is rotatably installed on a disc, the disc is rotatably installed on a fixed shaft, the fixed shaft is slidably connected to the inside of the base frame, a ratchet is fixedly installed inside the second gear, one end of a spring is fixedly installed on the fixed shaft, a pawl is fixedly installed on the other end of the spring, the pawl is clamped by a fixed block, two fixed blocks are arranged, and a control mechanism is arranged on the fixed shaft.

Since the pawl 12 is clamped on the ratchet 10 and the pawl 12 is also limited by the fixing block 13, the ratchet 10 cannot rotate clockwise, and the front universal wheel 2 cannot rotate clockwise. Therefore, when the patient goes uphill, the front universal wheel 2 can only rotate in one direction, thereby avoiding the situation of slipping, and ensuring the safety of the patient;

[0035] When the patient is walking on the ground, the first button 31 is used to control the micro hydraulic cylinder 15, so that the output shaft of the micro hydraulic cylinder 15 drives the fixed block 13 to move upward, and then drives the fixed shaft 9 to move upward, so that the fixed shaft 9 moves upward along the slide groove 34, and then drives the pawl 12 to move upward, so that the pawl 12 is disengaged from the ratchet 10. At this time, no matter whether the patient moves forward or backward, it will not affect the rotation direction of the front universal wheel 2, so that the patient can move freely.
