Description

Chair seat

Technical Field

The invention relates to the technical field of seats, in particular to a seat structure with a backrest and a cushion capable of swinging.

Background

Seats are generally composed of a frame, a seat cushion, a backrest, and the like. The cushion and the backrest of many seats are fixedly connected with the bracket, so that the cushion and the backrest can not swing and rotate, and the problem of low comfort exists. Meanwhile, the structure is not reasonable, so that the seat is inconvenient to install and disassemble. However, the conventional seat structure of the prior art has not effectively solved the above-mentioned problems. For example, CN 201784740U is a Chinese patent grant publication, and 2011 is 04 month 06, and the invention creates a multifunctional seat, and the patent discloses a seat structure, which can be used as a seat and can be used for placing things through combination innovation of a mounting plate, a seat plate, a backrest and the like, and has the characteristic of saving space, but the mounting plate, the seat plate and the backrest of the patent are all connected in a hinged manner, so that the problem of inconvenient mounting and dismounting exists. For example, in chinese patent application publication No. CN 103989335A, application publication date 2014, month 08 and day 20, the invention creates a stadium stand seat, and this patent application discloses a structure of a seat, and through the combination innovation of structures including a seat board, a seat back and a support, the seat has the characteristics that the structure is simple and the seat board can be automatically retracted, but the backrest of this patent application is fixedly connected with the support, and cannot rotate or swing, and has uncomfortable problems. The invention provides the seat which has the advantages of simple structure, low cost, convenient installation and disassembly, comfortable and convenient use, good safety performance and capability of swinging in a linkage way through the combination innovation of the structures such as the backrest, the cushion, the bracket, the rubber block and the like.

Disclosure of Invention

The invention solves the problems that the prior art is not comfortable and convenient to use and inconvenient to install and detach due to the structure of a common seat, and provides the seat.

In order to solve the technical problems, the invention adopts the following technical scheme: the utility model provides a seat, includes the support of back, cushion and left and right sides, its characterized in that, the middle part of support is equipped with the support frame, is equipped with the rubber piece on the support frame, is equipped with the clamp plate on the rubber piece, the middle part of clamp plate is equipped with the reference column with cushion looks adaptation, and the extension of clamp plate is equipped with the socket, the both sides of back lower part all are equipped with the connection piece, are equipped with the connecting bolt with socket looks adaptation on the connection piece.

During installation, the supporting frame is fixed in the middle of the corresponding bracket through bolts; then placing the rubber block on a support frame, placing a pressing plate on the rubber block, and connecting the pressing plate with the support frame through bolts; then the cushion is erected on the pressing plate through the positioning column; finally, the backrest is well spliced through the matching structure of the socket of the extension part of the pressing plate and the connecting bolt on the connecting sheet, so that the installation is completed. When a person sits on the seat, the cushion has certain pressure, the pressure acts on the pressing plate, the rubber block has a buffering effect, and the impact force of the cushion on a human body is reduced; when a person lies on the backrest, the gravity center of the person moves backwards, the rubber blocks incline backwards and downwards, the cushion and the backrest incline backwards and downwards, when the gravity center of the person moves forwards, the rubber blocks gradually reset, and the cushion and the backrest gradually reset, so that the linkage swing of the cushion and the backrest of the seat is realized, and the seat is comfortable to use. According to the invention, the cushion and the backrest are linked and rocked through the buffering and rebound effects of the rubber block, so that the use is very comfortable, the contact area of the rubber block is larger compared with a spring, the safety performance is better, and the use is more convenient compared with the manual adjustment of the inclination of the backrest; the positioning column and the seat cushion are matched in structure, and are fixed after sleeved, so that the seat cushion is convenient to install and detach; the socket and connecting bolt's grafting structure realizes the installation of back and dismantles conveniently.

Preferably, a plurality of transverse through holes are formed in the middle of the rubber block. The transverse through hole is simple in structure, so that the middle part of the rubber block has better buffering and rebound capacity, corresponds to the cushion, further reduces the impact force of the cushion on a human body, and is better in safety performance.

Preferably, a notch is arranged at the tail part of the rubber block. The notch, simple structure for the afterbody of rubber piece has better buffering and rebound ability, corresponds with the back, realizes that this seat sways more easily, uses more comfortablely.

Preferably, the seat further comprises a limit bolt, a long hole matched with the limit bolt is formed in the rear portion of the support frame, and the limit bolt penetrates through the long hole and is connected with the pressing plate. In the process of swinging the seat back and forth, the rubber block is in two states of compression and rebound, and the limit bolts limit the rebound amplitude of the rubber block, so that the human body can be effectively prevented from being ejected out of the seat due to overlarge rebound amplitude of the rubber block, and the safety performance of the seat is further improved.

Preferably, the two sides of the support are provided with support frames. The structure enables a plurality of seats to form a connected structure, in the structure of the connected seat, not only is the space saved, but also the using amount of the bracket is reduced, and the cost is reduced.

Preferably, connecting rods are arranged on two sides of the cushion, and mounting holes matched with the positioning columns are formed in the end portions of the connecting rods. Simple structure, simple to operate of cushion.

Preferably, the positioning column is a positioning bolt, and the positioning column passes through the mounting hole and then is connected with the connecting rod through a nut. Simple structure, simple to operate of cushion.

Preferably, the seat further comprises an armrest hinged to the top of the support.

Preferably, a cup seat is arranged at the end part of the armrest, and the cup seat and the armrest are of an integrated structure.

By adopting the technical scheme, the seat provided by the invention has the following beneficial effects: through the combination innovation of structures such as back, cushion, support and rubber piece, provide a simple structure, with low costs, the installation is dismantled conveniently, and convenient to use is comfortable, and the security performance is good, and cushion and back can link the seat of swaing.
