Abstract

The utility model relates to a chair technology, in particular to a chair tray structure. According to the technical scheme, the chair tray structure comprises a base frame, a chair back fixing seat and a telescopic rod, wherein the chair back fixing seat is hinged on the base frame, two ends of the telescopic rod are hinged on the chair back fixing seat and the base frame respectively, and the telescopic rod can stretch axially. The chair tray structure can be used for adjusting the inclination angle of a chair back, is simple to operate, and enables deck chairs to be produced in large scale so as to improve the production efficiency.

Description

A kind of chair tray structure

Technical field

The utility model relates to chair technology, particularly a kind of chair tray structure.

Background technology

Chair tray structure of the prior art, if Granted publication number is the disclosed a kind of chair tray structure of utility model patent of CN202515072U, be provided with the connecting plate being connected with cushion, described connecting plate is provided with the end that is fixedly connected with that cushion can be connected to one with chair back end support portion, connecting plate has a pallet mouth, described connecting plate is connected with supporting walls along described pallet mouth, described supporting walls and described connecting plate surround a dented space, described supporting walls is provided with a lever bracket, described lever bracket is connected with air spring control lever, described air spring control lever comprises in dented space and contact-segment air spring effect described in position ten and is positioned at the handle section for people's operation in dented space outside.

For the more existing chair back that can lie low, design also concentrates on the chair back or seat substantially, usually ignores pallet, so volume production on a large scale.

Utility model content

The purpose of this utility model is to provide a kind of chair tray structure, and the elevation angle that it can adjusting back, and simple to operate also makes the rota-cline seat can scale of mass production, enhances productivity.

Above-mentioned technical purpose of the present utility model is achieved by the following technical programs: a kind of chair tray structure, comprise pedestal, this kind of chair tray structure also comprises that the chair back holder, the two ends that are articulated with described pedestal are articulated with respectively described chair back holder and described pedestal and expansion link that can axial stretching.

As of the present utility model preferred, the hinged place between described expansion link and described chair back holder is in the vertical lower than the hinged place between described expansion link and described pedestal.

As of the present utility model preferred, described expansion link is air spring.

As of the present utility model preferred, the cylinder barrel of described air spring is articulated with described chair back holder; The piston rod of described air spring is articulated with described pedestal by Connection Block.

As of the present utility model preferably, described Connection Block comprises piston rod fixed head, is fixedly arranged on described piston rod fixed head both sides and is articulated with the articulated slab of described pedestal respectively; Described air spring switch through described piston rod fixed head two described articulated slabs; Described pedestal is provided with the chair back regulating handle that can act on described air spring switch.

As of the present utility model preferably, described chair back regulating handle comprise be rotationally connected with the bull stick of described pedestal and be fixedly arranged on bull stick and between two described articulated slabs for acting on the triggering sheet of described air spring switch.

In sum, the utlity model has following beneficial effect: the utility model is simple in structure, easy to implement; Also be provided with the fixed head being fixedly connected with seat support at pedestal; While assembling with chair, as long as pedestal is fixedly connected with seat support, chair back holder is fixedly connected with the chair back, therefore assembling is simple; By the flexible reclining that realizes the chair back of expansion link, simple to operation; Thereby also make the rota-cline seat can scale of mass production, enhance productivity.
