Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of medical devices, concretely relates to a kind of anti-falling walking aid. BACKGROUND

[0002] Walking aid is the appliance that assists human body to support weight, keep balance and walk;It provides the guarantee of independent movement for the old and patients, and is widely used.The commonly used walking aid currently includes the power frame of U-shaped structure, the power frame includes the transverse side frame body at the left and right sides of human body, two transverse side frame bodies are connected by front side connecting frame and enclose the U-shaped space with rear open, two transverse side frame bodies are arranged in parallel, and the transverse side frame body usually has support leg on the front and back sides, the support leg has the structure form with walking wheel and without walking wheel, the transverse side frame body has top beam for hand holding to provide support to human body, and sometimes the middle part of front side frame body is also designed with the seat plate that can be turned over, the seat plate is turned up when walking, and the seat plate is turned down when needed, and the turnable end is supported on the transverse side support to provide the user to sit down and rest.But the existing walking aid uses the hand power of user to support, however, in the actual clinical use process, the patient's hand power is temporarily insufficient (such as the sudden weakness of body, or the body imbalance occurs during movement, generally backward falling), and the user slips the walking aid, and the action of hand holding walking aid to avoid falling usually occurs, but due to the short transverse side frame of walking aid and parallel design, the walking aid itself is easily pulled over by user, so that effective help cannot be provided when the body of user loses balance. SUMMARY

[0003] In view of the defects of the prior art, the purpose of the utility model is to provide an anti-falling walking aid, which increases the stability of the bottom plate, and the user leans against the back plate and restrains the body and the back plate together through the connecting belt to avoid falling when the arm is weak.

[0004] The purpose of the utility model can be achieved by the following technical solutions.

[0005] An anti-falling walking aid, comprising:

[0006] A back plate, two sides of the back plate are fixedly connected with parallel arranged support rods, two ends of the support rod are fixedly connected with lifting rods, the lower end of the lifting rod is fixedly connected with a ring-shaped base, and the lower end of the ring-shaped base is provided with a plurality of uniformly distributed universal wheels.

[0007] Connecting belts, one end of the plurality of connecting belts is fixedly connected to one side of the back plate, and a plurality of equally spaced limiting holes are formed in the connecting belt.

[0008] A fixed plate is fixedly connected to the back of the backrest, a plurality of limiting columns are fixedly connected to the fixed plate, a threaded column is rotatably connected to the middle of the fixed plate, a pressing plate is threadedly connected to the threaded column, and a plurality of holes corresponding to the limiting columns are formed in the pressing plate.

At this time, the user can contact the walking aid to assist walking. The application increases the stability by increasing the chassis, and the user leans against the backrest and restrains the body and the backrest together through the connecting belt to avoid falling when the arms are weak.

[0011] Further, the lifting rod comprises a sleeve, the lower end of the sleeve is fixedly connected with the annular base, a sliding rod is slidably connected in the sleeve, the upper end of the sliding rod is fixedly connected with the support rod, a plurality of first perforations are formed in the length direction of the sliding rod, a second perforation is formed in the upper end of the sleeve, a bolt is penetrated through the first perforation and the second perforation, and a nut is threadedly connected with the bolt.

[0012] Further, a notch is formed in the annular base.

[0013] Further, the upper end and the lower end of the pressing plate are fixedly connected with a support plate, a limiting rod is slidably connected to the support plate, and the limiting rod is fixedly connected with the backrest.

[0014] Further, a knob is fixedly connected to the outer side end of the threaded column.

[0015] Further, anti-slip patterns are arranged on the circumferential side of the knob.

[0016] Further, the surfaces of the backrest and the support rod are wrapped with a soft layer.

[0017] Further, the outer side end of the limiting column is in a hemispherical structure.

[0018] The following explains the nouns, conjunctions or adjectives involved in the above technical solution:

[0019] Fixed connection refers to the connection of parts or components after being fixed, without any relative movement. It is divided into two types: detachable connection and non-detachable connection.

[0020] (1) detachable connection is to use screw, spline, wedge pin and so on to fix the parts together. This connection mode can be disassembled during maintenance, and the parts will not be damaged. But the specifications of the connecting parts (such as the length of the bolt, key, wedge pin) must be correct, and the fastening is appropriate.

[0021] (2) non-detachable connection mainly refers to welding, riveting and tenon fitting. Because it needs to be forged, sawed or oxygen cut to disassemble during maintenance or replacement, so the parts generally cannot be used twice. At the same time, attention should be paid to the process quality, technical detection and remedial measures (such as correction, polishing, etc.) during connection.

[0022] Threaded connection refers to the detachable connection of the connected parts by using threaded parts (or threaded parts of the connected parts).

[0023] Sliding connection refers to the contact between two objects, but not fixed, and the two can slide relative to each other.

[0024] Rotary connection refers to the connection between parts that allows parts to rotate relative to each other.

[0025] The beneficial effects of the present application are:

[0026] The application increases the stability by increasing the chassis, at the same time, the user backs the back plate and restrains the body and the back plate together through the connecting belt, so as to avoid falling down when the arm is weak. BRIEF DESCRIPTION OF DRAWINGS
