Abstract

The utility model discloses a structure for connecting a seat board and a chassis of a chair, mainly relating to a structure for connecting a seat board of an office chair and a chassis of a revolvingchair, which comprises the seat board (1) of the chair and the chassis (2). The back of the seat board (1) is fixed with more than two hat pins (11); the diameter of the pin hat (111) is larger thanthat of a pin pole (112); a chassis stand (21) of the chassis (2) is provided with more than two strip through holes (211) corresponding to the pins (11); the end part at the same side of the strip through holes (211) is provided with through holes (2111) with the diameter slightly larger than that of the pin hat (111); the hole diameter of the strip through holes (211) is slightly larger than that of the pin pole (112) and is smaller than that of the pin hat (111); and the chassis stand (21) is also provided with a locking device. The adoption of the connecting structure can not only separatethe seat board from the chassis conveniently, but also fast and tightly connect the seat board with the chassis, thus being capable of disassembling package to reduce occupation space when in storageand transportation and being fast and conveniently connected into a whole when in use.

Description

The syndeton on chair seat board and chassis

Technical field

The syndeton on the utility model chair seat board and chassis relates generally to syndeton, especially the office chair seat board of seat board and chair pin of seat and the syndeton between the runner chair sole dish.

Background technology

Existing office chair all is an integrative-structure mostly, and it is very big to take up room in storage and transport process, has expended very big accumulating resource, has increased carrying cost.On the recent market, folding office chair also occurred, its major function promptly is to realize in when storing that back is folding to lie low, and to reduce space hold, reduces carrying cost.The chair of this structure has just been realized the folding of back, but the chassis of chair and seat board still are one, and the structure of protrusion is arranged, inconvenience during the packing accumulating, also have a lot of idle spaces to slattern, so the improvement of the syndeton between chair seat board and the chassis is imperative.

Summary of the invention

The purpose of this utility model provides the syndeton on a kind of chair seat board and chassis, the user can be not by the dismounting on free-hand realization seat board of any instrument and chassis, separate packed and transported during with the realization accumulating, minimizing takes up room, save the accumulating resource, reduce carrying cost, need not any instrument during use, the free-hand purpose of installing and using rapidly.

The syndeton on the utility model chair seat board and chassis comprises chair seat board 1 and chassis 2, it is characterized in that the back side of described seat board 1 is fixed with plural band cap pin 11, and the diameter of the described head of a nail 111 is greater than the diameter of nail bar 112; The strip through-hole two or more 211 corresponding with pin 11 arranged on the subbase 21 on described chassis 2, described strip through-hole 211 more than two same to the end through hole 2111 of slightly larger in diameter in the head of a nail 111 diameters arranged, the aperture of described strip through-hole 211 be slightly larger than nail bar 112 diameter and less than the diameter of the head of a nail 111; On subbase 21, also has locked instrument.

The above-mentioned chair seat board and the syndeton on chassis, described locked instrument are to have contact with device 3, comprise that stay hook 31 is fixed on the seat board 1, and movable hook 32 is hinged on the subbase 21, and movable hook 32 is extended with fixed handle 33.

The above-mentioned chair seat board and the syndeton on chassis, nail bar 112 are exposed to the thickness that seat board 1 outer height is slightly larger than subbase 21.

The above-mentioned chair seat board and the syndeton on chassis, described fixed handle 33 has the through hole 34 of the pole 22 that can be placed in chassis 2.

Adopt the syndeton on above-mentioned chair seat board and chassis, realized that the chair seat board fixedlys connected with the removable of chassis, both can dismantle separation easily, can achieve a fixed connection securely rapidly again by locked instrument.Reduce and to take up room thereby when accumulating, can separate packing, very rapid during use, be connected and fixed easily, reach the effect of feeling at ease to use.

Fig. 4 is the syndeton normal operating condition figure on the utility model chair seat board and chassis.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Seeing Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, is the syndeton embodiment one on the utility model chair seat board and chassis:

Comprise chair seat board 1 and chassis 2, the back side of described seat board 1 is fixed with plural band cap pin 11, is four pins of symmetric arrays shown in the figure, be anchored on the seat board 1, the diameter of the described head of a nail 111 is "T"-shaped structure greater than the diameter of nail bar 112, sees shown in Figure 2; Four strip through-holes 211 are arranged on the subbase 21 on described chassis 2, these four strip through-holes are corresponding with four pins 11 on the seat board 1, the shape of four strip through-holes 211 is the same, head at one end has the through hole 2111 of slightly larger in diameter in the head of a nail 111 diameters, the aperture of described strip through-hole 211 be slightly larger than nail bar 112 diameter and less than the diameter of the head of a nail 111, so, the pin head of a nail 111 on the seat board 1 just can pass through hole 2111, see shown in Figure 3, mobile chassis 2 then, nail bar 112 is just done displacement at strip through-hole 211, sees shown in Figure 4; For fixed underpan 2, on subbase 21, also has locked instrument, be to have contact with device 3 shown in the figure, comprise that stay hook 31 usefulness screws or screw are fixed on the seat board 1, movable hook 32 is hinged on the subbase 21, movable hook 32 is extended with fixed handle 33, when chassis 2 is positioned the described position of Fig. 4, movable hook 32 is snapped on the stay hook 31, the fixed handle 33 of tying tight gets final product, chassis 2 like this just left-right and front-back can not be moved, and firmly is fixed on the seat board 1.

Further mode, described nail bar 112 is exposed to the thickness that seat board 1 outer height is slightly larger than subbase 21, has so limited subbase 21 along the axial displacement of pin, has increased steadiness, and subbase 21 is radially slided along pin.

Further mode has through hole 34 at described fixed handle 33, fixed handle 33 can be placed on the pole 22 on chassis 2 admittedly, has so just prevented touching or vibrations, the phenomenon that clasp releases.

Said structure has realized that the chair seat board fixedlys connected with the removable of chassis, both can dismantle separation easily by clasp, can achieve a fixed connection securely rapidly again.Reduce and to take up room thereby when accumulating, can separate packing, very rapid during use, be connected and fixed easily, reach the effect of feeling at ease to use.

Locked instrument of the present utility model can also be a mounting spring pin assembly on subbase 21, also can be horizontal door bolt device is installed on subbase 21.
