Detailed Description

The preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Example 1

The utility model provides a desk chair convenient to accomodate, as shown in fig. 1-5, including desk board 1, storage tank 2, bracing piece 3, cushion subassembly 4, compress tightly subassembly 5 and back subassembly 6, there is storage tank 2 through the screw rigid coupling in the middle of the desk board 1 bottom, there is bracing piece 3 storage tank 2 left and right sides all through the screw rigid coupling, the slidingtype is equipped with cushion subassembly 4 between 3 lower part front sides of the bracing piece of left and right sides, be connected with between 3 inboard lower parts of bracing piece and compress tightly subassembly 5, back subassembly 6 is installed to cushion subassembly 4 front side.

When needs accomodate this desk chair, at first lean on back subassembly 6 on cushion subassembly 4, then promote cushion subassembly 4 and move to the rear side, make to compress tightly subassembly 5 and no longer fix cushion subassembly 4, then fold the below that promotes storage tank 2 with cushion subassembly 4, it also moves to the inboard and goes on to compress tightly subassembly 5 simultaneously, fold the back that finishes at this desk chair, stop to move cushion subassembly 4, when needs use this desk chair, it moves to reset to pull cushion subassembly 4 to the front side, then push down cushion subassembly 4 through compressing tightly subassembly 5, it resets to rotate back subassembly 6 simultaneously, then can sit on cushion subassembly 4, use this desk chair.

Cushion subassembly 4 is including sliding sleeve 41, special-shaped pole 42, seat 43, square telescopic link 44, backing plate 45 and

first spring

46, 3 lower parts of bracing piece all slidingtype are equipped with sliding sleeve 41, be equipped with special-shaped pole 42 between the sliding sleeve 41 top, special-shaped pole 42 top rotary type is equipped with seat 43, there is square telescopic link 44 both sides all through the screw rigid coupling about seat 43 bottom front side, there is backing plate 45 through the screw rigid coupling between the square telescopic link 44 bottom, be connected with first spring 46 between backing plate 45 top and the seat 43 bottom.

When the desk and chair needs to be stored, firstly, the special-shaped rod 42 is pushed to move backwards to drive the seat plate 43 to move backwards, and further, the square telescopic rod 44 is driven to move backwards, so that the base plate 45 is driven to move backwards, when the base plate 45 leaves a pressing part of the pressing assembly 5, the first spring 46 in a stretching state is reset to drive the square telescopic rod 44 to retract, so that the base plate 45 moves upwards, then the base plate 45 and the upper device thereof can rotate downwards until the bottom of the base plate 45 is contacted with the left side of the special-shaped rod 42, when the special-shaped rod 42 moves backwards to a required position, the special-shaped rod 42 is stopped moving, when the desk and chair needs to be used, the special-shaped rod 42 is firstly pulled to move forwards to drive the seat plate 43 to move forwards, after the seat plate 43 moves out, the seat plate 43 is rotated to enable the seat plate 43 to be 90 degrees with the special-shaped rod 42, and then the base plate 45 is pulled to move downwards to be contacted with the ground, the first spring 46 is stretched and then the pad 45 is pressed by the pressing part of the pressing assembly 5, so that the seat plate 43 and the upper device thereof can be folded and placed under the storage box 2, thereby saving a large space.

The pressing assembly 5 comprises a sliding rail 51, a sliding block 52, a connecting rod 53 and an inclined plate 54, the sliding rail 51 is welded between the lower parts of the inner sides of the supporting rods 3, the sliding block 52 is arranged in the sliding rail 51 in a sliding mode, the connecting rod 53 is welded at the top of the sliding block 52, the inclined plate 54 is arranged at the front part of the connecting rod 53, and the inclined plate 54 is matched with the base plate 45.

When the backing plate 45 leaves the below of swash plate 54, the swash plate 54 no longer pushes down the backing plate 45 this moment, the backing plate 45 moves up under the effect that first spring 46 resets, simultaneously to the inside swing, when backing plate 45 and connecting rod 53 contact, the backing plate 45 of inward movement promotes connecting rod 53 and last device rearward movement, make connecting rod 53 and last device accomodate in storage tank 2 below, when needs use this desk chair, backing plate 45 and ground contact back, promote swash plate 54 and move forward and reset, make the swash plate 54 card in the top of backing plate 45, make the backing plate 45 fixed, so, not only can fix the backing plate 45 through the swash plate 54, make cushion subassembly 4 can support the people, also can accomodate simultaneously, can not occupation space.

Backrest subassembly 6 includes limiting plate 61, right angle board 62 and backup plate 63, and both sides all have limiting plate 61 through the screw rigid coupling about seat 43 front side, and equal rotary type is equipped with right angle board 62 in the limiting plate 61, has backup plate 63 through the screw rigid coupling between the 62 tops of right angle board.

When the desk or chair needs to be stored, the back plate 63 can be laid down to lean against the upper part of the seat plate 43, and then the desk or chair can be stored together with the cushion component 4, and when the desk or chair needs to be used, the back plate 63 can be rotated to reset.

Example 2

On the basis of embodiment 1, as shown in fig. 1, 2, 6 and 7, the seat cushion further comprises a pulling assembly 7, the pulling assembly 7 is connected between the seat plate 43 and the special-shaped rod 42, the pulling assembly 7 comprises a fixing rod 71, a long strip plate 72 and a second spring 73, the fixing rod 71 is welded on the left side and the right side of the upper portion of the rear side of the special-shaped rod 42, the long strip plate 72 is welded between the front ends of the fixing rods 71, and the second spring 73 is connected between the long strip plate 72 and the bottom of the seat plate 43.

When the backing plate 45 leaves the lower part of the sloping plate 54, the second spring 73 in the stretching state resets at this time, drives the seat plate 43 to automatically rotate downwards, so that the cushion assembly 4 can be directly stored only by pushing the special-shaped rod 42, and when the seat plate 43 rotates to reset, the second spring 73 is stretched again.

Still including promoting the subassembly 8, be connected with between heterotypic pole 42 and the right-angle plate 62 and promote the subassembly 8, promote the subassembly 8 including promoting piece 81, right-angle rod 82 and wedge 83, the inboard lower part of heterotypic pole 42 has all welded and has promoted piece 81, and right-angle plate 62 rotates hookup location and has all welded right-angle rod 82, and the wedge 83 has all welded the bottom of right-angle rod 82, wedge 83 and promotion piece 81 cooperation.

When seat 43 rotates, drive limiting plate 61 and rotate, and then drive right-angle rod 82 and wedge 83 and rotate, rotate at wedge 83 and when promoting the contact of piece 81, promote the piece 81 and promote wedge 83 and rotate for right-angle rod 82 and backup plate 63 rotate, backup plate 63 beats on seat 43, when wedge 83 left promotion piece 81, promotes piece 81 and supports right-angle rod 82, makes backup plate 63 position fixed. Thus, the backup plate 63 can be automatically folded, and the backup plate 63 can be prevented from being opened after being stored.
