Description

A wearable semi-squat support device

technical field

The invention relates to auxiliary equipment used by people when working, in particular to a stool-like object specially used by ground maintenance personnel.

Background technique

In today's society, there is a class of workers who need to frequently switch between walking and squatting, such as car maintenance workers, outdoor electric welders, etc. They often move and change positions during work, get up and move in a while, move to a certain position and squat down to work, and so on and so forth. Because of the need to move frequently, holding tools in hand, and having to move chairs or stools, it is very troublesome. In order to save trouble, most people choose to squat to work. In this way, squatting and working for a long time will have a bad impact on joints, knees, legs, waist muscles and blood circulation, which will cause great harm to the body and affect the health of workers.

In view of the above problems, the present invention proposes a semi-squatting support device that can be worn with you.

To achieve the above object, the present invention adopts the following technical solutions:

A wearable semi-squatting support device is characterized in that it consists of a double-leg support and a wearing device; the double-leg support includes two foldable supports arranged symmetrically on the left and right, two foldable supports The top contact parts are connected together by a universal movable connection structure; the foldable bracket is composed of a hip seat plate, an upper limb rod and a lower limb rod, and a telescopic support rod; the hip seat plate and the upper limb The rod is fixedly connected, the upper limb rod and the lower limb rod are hinged, the upper and lower limb rods are respectively provided with an upper hinge seat and a lower hinge seat, and both ends of the telescopic support rod are hinged on the upper hinge seat respectively. and the lower hinge seat; the telescopic support rod should meet the following technical requirements. When extending, ensure that the upper limb rod and the lower limb rod are in a straight line, which is suitable for the upright posture of the human leg. When retracting, ensure that the upper limb rod and the lower limb rod can be Folded into a suitable half-squatting posture angle; the wearing device is provided with elastic sleeves or straps on the ankle part of the lower limb rod and the upper part of the upper limb rod respectively, and a belt tied around the waist on the buttocks seat plate .

The universal movable connection structure may be a universal joint connection or a rope buckle connection structure.

Further, in order to increase the comfort, the surface of the above-mentioned buttocks seat plate is provided with a soft pad.

Further, in order to reduce the weight, the above-mentioned and telescopic support rods are made of aluminum alloy tubes.

Further, in order to increase the comfort, the above-mentioned straps are made of elastic rubber band material.

Further, in order to adapt to the different heights of the crowd, the above-mentioned lower limb rod is a pull-out type, that is, a pull-out inner rod is arranged in the lower limb rod, a spring pin is arranged on the pull-out inner rod, and the lower limb rod is provided with a corresponding spring pin. A row of pin holes, adjust the height according to the height before use.

When in use, it is directly worn behind the legs and hung on the waist. When the human body walks, the upper limb rod and the lower limb rod bend and straighten with the action of the knee, which does not affect normal walking. When sitting down, the angle between the upper body bar and the lower body bar becomes smaller, forming a stable triangle with the telescopic bar. In addition, the human feet form four support points on the ground, which can be transformed into a stool at any time, and the staff squat. It has a support like a stool at times, reducing the force of the knees, reducing the harm to the health of workers when they squat for a long time, and improving work efficiency.

Detailed ways

As shown in Figures 1-5, a wearable semi-squatting support device is composed of a double-leg support and a wearing device; the double-leg support includes two foldable supports arranged symmetrically on the left and right, two The tops of the foldable brackets are connected together by a universal movable connection structure 1; the universal movable connection structure can be a universal joint connection structure or a rope buckle connection structure; the foldable bracket is composed of The hip seat plate 2, the upper limb rod 3, the lower limb rod 5, and the telescopic support rod 9 are composed; the hip seat board 2 and the upper limb rod 3 are fixedly connected, the upper limb rod 3 and the lower limb rod 5 are hinged with the shaft 4, and the upper limb rod 3 The upper hinge seat 8 and the lower hinge seat 10 are respectively provided behind the lower limb rod 5, and the two ends of the telescopic support rod 9 are hinged on the upper hinge seat 8 and the lower hinge seat 10 respectively; the telescopic support rod 9 When extended, the upper limb rod 3 and the lower limb rod 5 are in a straight line, and when retracted, the upper limb rod 3 and the lower limb rod 5 can be folded into a semi-squatting posture (135-degree angle); The ankle part of the lower limb rod 5 is provided with an elastic sleeve 7 , the upper part of the upper limb rod 3 is provided with a strap 12 , and the buttock seat plate 2 is provided with a lifting belt 13 tied around the waist. In order to adapt to the different heights of the crowd, the above-mentioned lower limb rods are of the pull-out type, that is, a pull-out inner rod 6 is provided in the lower-limb rod 3, a spring pin is provided on the pull-out inner rod 6, and a spring pin is provided on the lower limb rod 5 For the row of pin holes 11 corresponding to the pins, the height of the lower limb rod 5 is adjusted according to the height before use.
