Description

Hard bar chair capable of realizing lifting function

Technical Field

The utility model relates to a bar chair manufacturing technical field specifically is a can realize elevating function's hard bar chair.

Background

The furniture made of the industrial wind is the favorite of many young people who pursue personality and freedom, and the iron art material is tough and durable, gives off the special luster and texture of metal, and brings very good effect in vision. The metallic luster gives people a cold feeling, and the metallic luster is matched with wooden dining tables and cloth furniture, so that the metallic luster is rough in cold and does not lose the aesthetic feeling. The industrial air bar chair is placed in a house, so that the whole home environment is more artistic.

Most industrial wind bar chairs are embodied on chairs made of iron materials and hard materials, the upper structure has various seat surfaces, and the lower structure is mostly chair feet or chair legs with different shapes and iron materials. Most of the common industrial wind-hard bar chairs are fixed, and have less lifting function. Few hardware industrial bar chairs with lifting function currently use screw rotating structures to realize the height of the seat surface.

As in application No.: 201921107450.5, a bar chair, includes stool portion, is used for supporting stool portion's supporting part, locates the foot rest portion of putting on the supporting part, the supporting part includes the base and installs in base stabilizer blade all around, adjusting screw is installed to stool portion lower extreme terminal surface, adjusting screw is fixed in the base along vertical direction sliding connection in base and circumference, adjusting screw threaded connection has the application of force cover, the application of force cover is located the base below and rotates and connect in the base, application of force cover and base are axial fixity. Although the invention drives the adjusting screw rod to move along the vertical direction relative to the supporting part by rotating the force application sleeve, the distance between the stool part and the foot rest part is adjusted, and the feet can be comfortably placed on the foot rest part. The bar chair can adjust the height of the stool part by a rotating lifting mode at present, is more strenuous and inconvenient, and is particularly not suitable for people with inconvenient actions.

Although the industrial hard bar chairs have various modeling process styles, many industrial hard bar chairs cannot realize the function diversification of the bar chairs, such as easily realizing the lifting height of the bar chair seat surface, and realizing the simple and elegant modeling, and the industrial hard bar chairs have certain advantages in cost.

SUMMERY OF THE UTILITY MODEL

The principle of the lifting air rod is that the lifting device is provided with an air pressure rod which is an elastic element which takes air and liquid as working media and has the functions of supporting, buffering, braking, height adjusting, angle adjusting and the like. The lifting shaft is lifted to the highest point without applying external force to the lifting shaft. The gas spring can be stopped at any position in the stroke by means of the release device, has large locking force after stopping, and can be matched with the handle at present to realize the lifting function of the chair.

Preferably, the circular tray structure is characterized in that the bottom of the air rod insertion sleeve is fixed on the upper portion of the arch-shaped piece, the bottom of the arch-shaped piece is fixed on the upper portion of the outer circular support, the outer circular support is provided with a plurality of bolt holes, and the hook handle is inserted into the gap of the holes of the outer circular support and fixed on the inner side of the arch-shaped piece.

As the optimization of the technical proposal, the upper end of the lifting air rod is sleeved with a safety air rod cap.

As the optimization of the technical scheme, the stool surface can be subjected to processes of plastic spraying, electroplating and wire drawing.

Preferably, a round footrest is fixed at the middle-lower end position of the inner sides of the two groups of chair legs.

Preferably, the bottom of the chair leg is fixed with a foot nail.

The utility model discloses the ingenious use of well accessory: the hook handle is fixed at the bottom of the circular tray, the rod part of the handle is bent, and the bending part can increase certain strength, so that the hook handle is not easy to clamp hands when being operated, and time and labor are saved; the safety air rod cap can well protect the upper end of the lifting air rod, and can play a role in protecting when the lifting air rod is not operated properly; the gas pole is fixed to be sheathe in wide down narrowly, has used throat gas pole, puts into throat gas pole behind the fixed cover of gas pole, and is difficult for the landing, simple and practical.

The utility model discloses following beneficial effect has:

1. the lifting air rod is used in the hard bar chair, the lifting can be stopped at any position in the stroke, and the lifting air rod has large locking force after stopping, and is matched with the hook handle for use, so that the lifting function of the bar chair can be realized.

2. The accessory hook handle is not easy to clamp hands, and time and labor are saved; the safety air rod cap is used, so that the protection effect can be achieved when the lifting air rod is prevented from being operated improperly; the gas pole is fixed to be sheathe in wide down narrowly, uses with throat lift gas pole cooperation, puts into throat gas pole behind the fixed cover of gas pole, and difficult landing is simple and practical.
