Description

A student laboratory chair

technical field

The utility model relates to a chair, in particular to a student laboratory seat.

Background technique

Chairs are very common, and there are many types of chairs, such as fixed chairs arranged in most places in public places, swivel chairs arranged by office workers in the workplace, adjustable seats used in high-speed trains and other vehicles, etc. The prices of various different types of chairs also vary in thousands ways, especially for some adjustable seats, although it is very convenient to use, the price is very expensive, which affects its popularization and application. The student group occupies a considerable part of the number in our country. University laboratories are an important place for students to conduct experiments and complete work results. Some experiments need to be carried out continuously for a long time, and may last as long as two or three days. The experimental process must To be present, this requires the student to be in the lab for extended periods of time. At present, students usually sit on chairs to rest when doing experiments, and the labs are generally equipped with relatively cheap fixed chairs. The chairs can only sit, not lie down, and the adjustable chairs are limited by the high price. University laboratories are generally not configured. Therefore, it is very important to invent an inexpensive chair that can be used for students to both lie down and sit on.

Utility model content

In order to overcome the deficiencies in the prior art, the utility model provides a student laboratory chair with a reasonable and simple structure design, which can be used as a chair or as a simple bed. The technical solution adopted by the utility model is :

A student laboratory seat, comprising a back board, a seat board, an armrest, and outriggers. One end of the armrest is connected with one end of the seat board through a hinge, the armrest is fixed with a connecting rope, the end of the connecting rope is provided with a bolt, and the two sides of the backboard are provided with pin holes, and the bolt is inserted into the pin hole. A telescopic support is provided, and the telescopic support is fixedly installed under the seat plate through a bracket, and the telescopic support includes an outer frame and a support cloth.

Further, the telescopic support is a multi-stage telescopic rod structure.

The beneficial effects of the utility model are:

(1) The angle of the backboard 1 of the utility model can be adjusted, and it can be placed at the same level as the seat board when resting as a simple bed, and the structure design is reasonable;

(2) A telescopic support structure is added under the seat board to facilitate the reasonable adjustment of the length of the bed, suitable for people of different heights, wide adaptability and comfort.

detailed description

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in Figures 1-3, a student laboratory chair of the present invention includes a backboard 1, a seat board 2, an armrest 3, and legs 4, and two armrests 3 are provided on the seat board 2 respectively. On both sides of the seat, the legs 4 are fixedly installed under the seat board 2, one end of the back board 1 is connected with the end of the seat board 2 through a hinge 5, and the armrest 3 is fixedly provided with a connecting rope 6, and the ends of the connecting rope 6 A latch 7 is provided, pin holes are provided on both sides of the backboard 1, the latch 7 is inserted into the pin hole, a telescopic support 8 is provided below the seat board 2, and the telescopic support 8 is fixedly installed under the seat board 2 through a bracket 9, The telescopic support 8 includes an outer frame 81 and a support cloth 82 .

The telescopic support 8 is a multi-stage telescopic rod structure.

The utility model adds the telescopic support 8 and the angle adjustment of the backboard 1 on the basis of the traditional student laboratory chair, so as to realize the normal function of the seat and keep the backboard 1 and the seat board 2 in the same position. In the horizontal position, telescopic support 8 is set to increase the overall length of the device, which is more comfortable when used as a bed. The telescopic support 8 includes an outer frame 81 and a support cloth 82. Since the outer frame 81 is a telescopic structure, the support cloth 82 is also flexible and foldable, so the telescopic support 8 can change the length along the direction of the seat board 2, and the students lie down and have a rest. When the telescopic support 8 can be pulled to the position of suitable length, the pin is placed on the support cloth 82, so that it is more comfortable to sleep.

When the utility model is normally used as a seat, the backboard 1 is turned over to a position substantially perpendicular to the seat board 2 along the hinge 5, and the pin hole between the armrest 3 and the backboard 1 is locked by the latch 7, so that the backboard 1 is kept in a stable position, and the telescopic support 8 is retracted to the position of the lower part of the seat plate 2, which can be used like a common seat at this moment.

When used as a bed rest, place the backboard 1 at the same horizontal position as the seat board 2, use the latch 7 and the connecting rope 6 to fix the backboard 1 in the horizontal direction, and stretch the telescopic support 8 to a suitable position at the same time, At this time, students can lie down and rest on it.

The utility model improves the seat structure used in the traditional student laboratory, so that the seat can be used as a normal chair and as a simple bed for resting. The structure design is very simple, the manufacturing cost is low, and it is suitable for popular use.
