Preferably, the back of the chair back portion and the bottom of the chair seat portion are respectively provided with support belts, the support belt is provided with collars at both ends, the collars are set on the chair frame on each side, falling on top of the front connection block and said rear connection block. The collars are driven by the chair frame to pull away the support belt, which supports the chair back portion and the chair seat portion to enhance the weight-bearing performance of the chair cover.
Preferably, the resilient buckling element is a resilient buckle, the resilient buckle comprises a jumping bead and a spring element, the spring element pushes said jumping bead to pop out and engage in the positioning hole.
Preferably, the sleeves are provided with an oblique surface with guiding function. When the resilient buckle is inserted into the sleeve, the resilient buckle enters along the project of the oblique surface and is pressed by the oblique surface to slide into the positioning groove without manual pressure on the resilient buckle.
Preferably, the resilient buckling element is a wire spring, the wire spring is engaged into the positioning groove or the positioning hole.
Preferably, the head of the wire spring is provided with a ramp with guiding function. When the sleeve is inserted, the wire spring enters the sleeve through the ramp, is pressed by the sleeve, slides into the positioning hole or the positioning groove, the wire spring springs back and engages into the sleeve, and when pulling out the sleeve, the wire spring can be released from the positioning hole or the positioning groove by simply dragging the sleeve.
Preferably, the chair frame includes a plurality of sub-brackets, chair seat brackets and chair back brackets; the chair seat brackets are provided with sliding grooves, the chair back brackets penetrate through the sliding grooves to cooperate with the chair seat brackets, the chair back brackets and the chair seat brackets can slide through the sliding grooves to be folded for storage or unfolded, and the sub-brackets support the chair seat brackets and the chair back brackets.
The present disclosure has the following advantageous effects:
The present disclosure comprises a chair frame and a chair cover, wherein the chair frame is provided with a resilient buckling element, sleeves are respectively provided on the chair back portion and the chair seat portion, the chair cover is sleeved on the chair frame, the resilient buckling element is engaged into the positioning hole. Though the configuration of the resilient buckling element, the chair frame and the chair cover can be separated, easily be disassembled, the chair cover is easily cleaned. If the chair frame or the chair cover is damaged, it is easy to replace.
In the present disclosure, the chair back portion and the chair seat portion are fixed to the sleeve by means of the resilient buckling element and connected to the chair frame. The resilient buckling element and the sleeve are simple in structure, low in consumable material and simple in production process. The sleeve is arranged on the chair cover, when the user sits on the chair cover, the pressure is exerted on the chair frame toward the outside of the chair frame, which is balanced by the pull of the chair cover on the sleeve and enhances the stability of the chair. At the same time, the chair cover is provided to prevent the top tip of the chair frame from scratching the user.
