Detailed Description

The following describes the present invention in further detail with reference to the accompanying drawings.

A spliced chair, which is combined with figures 1-3, comprises a chair seat 1, a chair back 3 and chair legs 2. Referring to fig. 3 specifically, the seat 1 is U-shaped, two sides of the bottom of the seat 1 are folded upwards and then folded outwards to form the armrests 1b, and the width of the vertically folded parts is gradually narrowed relative to the bottom of the seat 1. The two chair legs 2 are in an inverted U shape with the same side formed integrally, and the front end and the rear end are obliquely and outwards expanded so as to improve the support stability. The chair back 3 is shaped like a Chinese character 'ji', and the two sides of the chair back 3 are provided with flanges 3a, so that the supporting strength of the chair back 3 is improved.

With reference to fig. 3 and 6, the left and right sides of the bottom of the seat 1 are respectively provided with two side insertion ports 1a facing the legs 2; the side inserting port 1a is I-shaped, and an I-shaped side inserting block 2a is correspondingly arranged on the inner side wall of the chair leg 2. With reference to fig. 4, after the side insertion block 2a is inserted into the side insertion port 1a, the primary positioning and fixing of the seat 1 and the legs 2 are realized; then, a fastener is screwed in from a mounting hole at the bottom of the side plug-in port 1a and is in threaded connection with the side plug-in block 2a, so that the seat 1 and the chair legs 2 are reliably connected.

Wherein, the section between two side inserted blocks 2a of chair leg 2 is the type of falling V, and this section just in time laminates in vertical turn-over position to play certain supporting role to this position. The side plug block 2a can be provided with a certain taper, so that the side plug interface 1a is convenient to insert.

With reference to fig. 5 and 6, a rear socket 1c is disposed at the rear side of the seat 1, and the backrest 3 is fixedly mounted at the rear side of the seat 1 through the rear socket 1 c; the rear insertion port 1c is transversely provided with a row along the chair seat 1, the inner surface of the chair back 3 is transversely provided with a row of rear insertion blocks 3c matched with the rear insertion port 1c, and the rear insertion port 1c and the rear insertion blocks 3c are both square structures. The inside opening that sets up of back inserted block 3c sets up the screw thread post in the opening, after seat support 1 and the preliminary concatenation laminating of the back of the chair back 3, the fastener penetrates from the mounting hole at back interface 1c back (in order to avoid interfering, the mounting hole setting of the back interface 1c at both ends is in the bottom) to with screw thread post threaded connection, realize the reliable connection of seat support 1 and chair leg 2.
