Description

Simple rotary connecting structure suitable for waist support seat

Technical Field

The utility model relates to a seat manufacturing and designing field, concretely relates to simple and easy swivelling joint structure suitable for waist holds in palm seat.

Background

The chair is a piece of furniture with wide application in daily life and work, generally comprises a base, a backrest, a supporting structure, armrests and other parts, and in order to meet personalized requirements of people and bring more comfortable and healthy use experience, the structure and the function of the chair are continuously improved. When a user uses the seat, the user usually supports the buttocks and the back by the base and the backrest, the support of the waist is relatively weak, the muscle and the vertebra of the waist and the back of the human body bear the pressure of the weight of the upper part of the human body, and in the long term, lumbar muscle strain and vertebra pathological changes can occur, so that inconvenience in study, life and work is brought to people.

In recent years, in order to provide a supporting force to the waist, a seat with a waist support is on the market, and the waist support is connected to a base or a backrest to provide a good supporting force to the waist of a user, so that the user can keep a sitting posture upright and has a good protection function to the lumbar. However, the waist support positions of some waist support seats are fixed, and due to different factors such as the body shapes and the weights of users, the waist support seats cannot carry out good fit support on each user. Part waist holds in palm seat and possesses the elasticity regulatory function, but the elasticity provides the mode and can uses drive structures such as air spring, gas pole of placing in seat below position, though the holding power is good but the cost is expensive, has promoted the manufacturing cost and the selling price of whole seat.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's is not enough, provides a simple and easy swivelling joint structure suitable for waist holds in the palm seat, simple structure, and the cost is controllable, does benefit to the implementation, and the waist holds in the palm can laminate the adjustment along with human action.

The above technical purpose of the present invention can be achieved by the following technical solutions: a simple rotary connecting structure suitable for a waist support seat comprises a supporting body, wherein the supporting body is connected with a rotating arm; the rotary connecting structure further comprises an elastic body and a fixing piece, wherein one end of the elastic body is connected with the rotating arm, and the other end of the elastic body is connected with the fixing piece.

As the utility model discloses a preferred, the supporter is waist support or waist leans on.

Preferably, the rotation direction of the rotating arm is a horizontal rotation direction.

As the utility model discloses a preferred, the elastomer is the torsional spring, include the rotatory shell on the rocking arm, torsional spring one end with rotatory shell is connected, the other end with the mounting is connected.

As the utility model discloses a preferred, the mounting is connected with the multiangular axle, the mounting with the multiangular axle all extends in vertical direction, be equipped with the confession on the mounting the multiangular groove that the multiangular axle stretched into.

As an optimization of the present invention, the polygonal shaft is connected to the armrest.

As the utility model discloses a preferred, the many horn shafts pass through fixation nut with the handrail is connected, the handrail with be equipped with the gasket between the fixation nut.

To sum up, the utility model discloses following beneficial effect has:

1. the waist support can rotate, so that the waist support adapts to the sitting posture of a human body and supports the waist in time.

2. The torsional spring is used as a power and elastic component, can be attached to the waist and the back of a human body, and is good in comfort.

3. The cost is controllable, and the structure is simple.

Drawings

FIG. 1 is a schematic diagram of a first embodiment;

fig. 2 is a schematic view at a of fig. 1.

In the figure: 1. handrail, 2, support body, 3, rocking arm, 31, rotatory shell, 4, elastomer, 5, mounting, 6, many angle shafts, 7, fixation nut, 8, gasket.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.

Example 1 includes a support body 2, and the support body 2 may be a waist support or a backrest depending on the shape and height position. The support body 2 is connected with a rotating arm 3, when the waist and the back of a user move, the support body 2 also moves in a fit manner, and the rotating arm 3 also rotates in the horizontal direction. As shown in fig. 2, the elastic supply of the support body 2 is derived from the elastic body 4 in the figure.

In this embodiment, the elastic body 4 may be a torsion spring, one end of which abuts against the fixing member 5 and the other end of which abuts against the rotating shell 31. The rotating arm 3 rotates the rotating shell 31, while the fixed part 5 is stationary. During the rotation of the supporting body 2, the torsion spring is compressed by the relative movement of the rotating case 31 and the fixing member 5, thereby generating an elastic force, and finally the elastic force is fed back to the supporting body 2.

The fixing piece 5 extends in the vertical direction, the handrail 1 is connected with a polygonal shaft 6, the polygonal shaft 6 can be a hexagonal shaft and also extends in the vertical direction, and the fixing piece is fixedly connected with the handrail 1 through fixing nuts 7 and gaskets 8 at the upper end and the lower end. The fixing member 5 may be formed with a groove for cooperating with the polygonal shaft 6, so as to complete the fixed connection with the polygonal shaft 6 and prevent the rotation in the horizontal direction.

To this end, the support body 2 provides a support for the waist or the back of the human body, and when the human body leans back, the torsion spring is compressed to generate an elastic force and feed back to the back of the human body to provide a sufficient support force. When the human body leans forward, the torsion spring rebounds, the support body 2 resets and is attached to the waist and the back of the human body constantly.
