Abstract
The utility model relates to the particular technical field, in particular to a screw-free fixing device for a seat cushion and a chassis of an office chair, and the device is a connecting mechanism of the seat cushion and the chassis. A T-shaped round cap is arranged on the upper surface of the chassis; a large hole and a small long hole crossed with the large hole are arranged on a buckling plate of the seat cushion; an elastic sheet is arranged above the large hole, and the rear part of the elastic sheet is arranged above the cross part of the large hole and the small long hole; the diameter of the large hole is slightly larger than the diameter of the large circle at the upper part of the T-shaped round cap, the width of the small long hole is slightly larger than the diameter of the small circle at the lower part of the T-shaped round cap, and the length of the small long hole is slightly larger than the sum of the diameter of the large circle at the upper part of the T-shaped round cap and the diameter of the small circle at the lower part of the T-shaped round cap; and when the elastic sheet is in natural status, the interval between the rear part of the elastic sheet and the upper surface of the buckling plate is smaller than the thickness of the large circle at the upper part of the T-shaped round cap. When the device is in use, the T-shaped round cap enters the large hole, translates, ejects open the elastic sheet so as to enter the small long hole, then the elastic sheet homes and limits the movement of the T-shaped round cap. With the adoption of the device, the service life of the office chair is prolonged, and the device is simple to assemble.
Description
Technical field
The utility model relates to the furniture technical field, and a kind of office chair seat cushion and chassis screw-free fixing device specifically are provided.
Background technique
Known office chair all comprises seat cushion, chair pin and the chassis portion that connects seat cushion and chair pin, adopts screw etc. to be rigidly connected between seat cushion and the chassis.Using such is rigidly connected and has following defective:
One, will inevitably produce some when the people is sitting on the seat cushion and rock, the screw thread place of screw forms stress and concentrates tired easily and permanent damage.
Need special tools such as screw-driver when two, assembling, comparatively complicated.And be not suitable for installing and removing repeatedly, otherwise can destroy the screw thread of screw, screw.
Three, assembling back chair takes up room greatlyyer, increases transportation and warehouse cost.
The model utility content
At problems of the prior art, the utility model provides a kind of office chair seat cushion and chassis screw-free fixing device.
To achieve these goals, the utility model office chair seat cushion and chassis screw-free fixing device are the bindiny mechanism on seat cushion and chassis.The upper surface on chassis is provided with T type circle cap.The buckle of seat cushion is provided with a macropore, and the little slotted hole that intersects with macropore.The top of macropore is provided with a shell fragment, and the shell fragment afterbody places macropore and top, little slotted hole intersection.The slightly larger in diameter of macropore is in the top axis of great circle of T type circle cap.The width of little slotted hole is slightly larger than the axis of small circle of T type circle cap bottom.Little slotted hole length is slightly larger than T type circle big circle radius in cap top and bottom roundlet radius sum.Shell fragment is in the raw the time, and the gap of shell fragment afterbody and buckle upper surface is less than the thickness of T type circle cap top great circle.T type circle cap enters the macropore translation and backs down shell fragment and enters little slotted hole and limit its activity by shell fragment during use.
The utility model office chair seat cushion and chassis screw-free fixing device fixedly need not screw during seat cushion, and slightly not rocking of seat cushion can cause substantial infringement to any part, prolonged the working life of seat.During use, only need T type circle cap with the chassis to insert the macropore of seat cushion buckle and, withstand T type circle cap to the shell fragment side direction that playbacks fully behind the first jack-up submissile sheet, seat cushion can be fixed, operate very easy toward little slotted hole direction pushing.

Embodiment
Below in conjunction with accompanying drawing the utility model preferred embodiment is further specified:
Fig. 1 is the structural representation of the utility model office chair seat cushion and chassis screw-free fixing device; Fig. 2 is a T type circle cap of the present utility model joint partial enlarged drawing; Fig. 3 is the structural drawing on the utility model chassis; Fig. 4 is the structural drawing of the buckle of the utility model seat cushion.
As shown in the figure, the utility model office chair seat cushion and chassis screw-free fixing device are the bindiny mechanism on seat cushion and chassis.The upper surface on chassis 01 is provided with T type circle cap 11.The buckle 02 of seat cushion is provided with a macropore 22, and the little slotted hole 21 that intersects with macropore 22.The top of macropore 22 is provided with a shell fragment, and shell fragment afterbody 25 places macropore 22 and top, little slotted hole 21 intersections.The slightly larger in diameter of macropore 22 is in the top axis of great circle of T type circle cap.The width of little slotted hole 21 is slightly larger than the axis of small circle of T type circle cap bottom.Little slotted hole 21 length are slightly larger than T type circle big circle radius in cap top and bottom roundlet radius sum.Shell fragment is in the raw the time, and the gap of shell fragment afterbody 25 and buckle 02 upper surface is less than the thickness of T type circle cap top great circle.T type circle cap enters macropore 22 translations and backs down shell fragment and enters little slotted hole 21 back shell fragment playback and limit its activity during use.Described shell fragment is connected macropore 22 and little slotted hole 21 opposite sides by joint 24 and buckle 02 upper surface.Described shell fragment afterbody 25 is downward-sloping with respect to shell fragment middle part 23.
The utility model office chair seat cushion and chassis screw-free fixing device can prolong the working life of chair, and assembly operation is easy.
