The ① multifunctional chassis of the invention is a self-developed design, different from the common multifunctional chassis, which has straight handles at the bottom to adjust the inclination of the seat, the structural design needs the consumer to bend down to the bottom of the seat to complete the operation, and is very inconvenient for people with inconvenient movement and short stature, the original design of the common chassis is changed by the multifunctional chassis, multifunctional chassis with linkage mechanism and transmission mechanism are self-developed, the ① linkage mechanism is composed of a special-shaped connecting rod and a driving rod, the special-shaped connecting rod is distorted, compared with the conventional molded connecting rod, holes at two ends are in the same plane with , 2 holes at left and right of the distorted connecting rod form 90 degrees, the direction of the holes is changed, the novel and unique modeling also enhances the push-pull power of the linkage mechanism, the ② transmission mechanism is composed of a transmission rod, a fixed seat and a shaft coupling piece, wherein the shaft coupling piece is a detachable part, the length of the handle at the front end can be replaced freely, the operation of the seat is achieved easily, the multifunctional chassis is a push-pull power of the linkage mechanism, the linkage mechanism is composed of a ② transmission rod, the linkage mechanism is composed of a push-pull rod, the linkage mechanism is composed of a linkage mechanism, the linkage mechanism is formed by a plastic sleeve, the linkage mechanism, the handle is not only has a plastic sleeve, the handle is used for locking mechanism, the handle is not only has a locking mechanism, the handle is not only has a locking mechanism, the cost is reduced, the cost.

Preferably, the upper end hole sites of the plurality of inserting pieces penetrate through the sleeve and are fixed on the inner side of the locking support, the lower end hole sites penetrate through the inserting piece pins and are fixed on the inner side of the inserting piece fixing piece, and the outer end of the sleeve is locked by a plastic bolt cover.

Preferably, the th fixed seat and the second fixed seat are composed of a fixed plastic part and a fixed cover, and the fixed cover and the fixed plastic part are locked by bolts, the th fixed seat and the second fixed seat are fixed at two ends of the transmission rod, so that the bending handle is stressed more uniformly and is not easy to shake when operated.

Preferably, as for the above technical solution, a fixed bottom piece is arranged at the bottom end of the th fixed seat and is fixed with the th main piece.

Preferably, the multifunctional chassis is fixed to the seat bottom, and the exterior of the multifunctional chassis is locked by the chassis cover.

Preferably, in the above aspect, the upper portion of the air rod is inserted into the air rod insertion tube, and the lower portion is fixed in the hole of the seat leg.

When a consumer sits on the seat, only the bending handle needs to be held to open inwards, the transmission mechanism drives the driving piece on the linkage mechanism to form an opening angle of , the locking rod at the rear end of the special-shaped connecting rod is driven to operate, the front and back inclination adjustment of the seat is completed, time and labor are saved, and the operation is convenient.

Another objects of the invention are to provide novel office and leisure chairs with multifunctional chassis.

The invention has the following beneficial effects:

1. the multifunctional chassis which is independently researched and developed enhances the push-pull power of the linkage mechanism through the twisted design of the special-shaped connecting rod, the transmission rod and the bending handle are fixed at through the detachable design of the coupling piece, the stress of the bending handle is more uniform during operation, the bending handle is not easy to shake, the product packing amount is increased, the locking mechanism is more labor-saving to operate when matched with the linkage mechanism for use through designing the end of the locking rod into a bending type, the whole multifunctional chassis is novel in shape and low in manufacturing cost, the cost is reduced for enterprises, and the multifunctional chassis brings the benefits to consumers.

2. When the multifunctional chassis is arranged on the seat, the multifunctional chassis is fixed through the chassis cover, and is attractive and practical. When the bending handle is held by hand and the chair is opened inwards, the chair is adjusted by tilting forwards and backwards, time and labor are saved, and the operation is convenient. When holding the handle of bending and outwards opening, prevent that the seat from pushing forward, play fixed effect, the security performance is high.
