Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all the embodiments are protected by patent laws within the scope of the claims of the present invention.

Example (b): as shown in fig. 1, 2 and 3, a child seat includes a seat 1, a back 3, armrests 5, an armrest mounting frame 4 and a back mounting frame 2. The armrests 5 and the armrest mounting frames 4 are arranged on the left side and the right side of the seat 1, and the armrests 5 are mounted on the armrest mounting frames 4 on the corresponding sides. The lower end of the handrail mounting frame 4 extends downwards to the lower part of the chair seat 1 and is fixed on the chair seat 1, and the handrail 5 is rotatably installed at the upper end of the handrail mounting frame 4 and rotates up and down relative to the handrail mounting frame 4.

As shown in fig. 3, the upper end of the handrail mounting frame 4 extends forward to form a suspended holding portion 41 for receiving the handrail 5, the rear end of the handrail 5 is hinged to the holding portion 41, and the front portion of the handrail 5 is pressed downward against the holding portion 41. The lower end of the holding portion 41 is provided with a holding area 43, which not only facilitates the hand holding the armrest 5, but also provides a space for deformation when the holding portion 41 is pressed downward.

As shown in fig. 1, the armrest 5 has a U-shaped cross section and has a U-shaped groove with a downward opening for fastening to the grip portion 41. An end plate 42 for abutting against the inside of the U-shaped groove is provided at the front end of the grip portion 41. The handrail mounting frame 4 has a sheet structure, and the arrangement of the end plate 42 prevents the handrail 5 from being swung to the left and right when being fastened to the grip portion 41.

As shown in fig. 1 and 2, the backrest 3 is disposed at the rear side of the seat 1, the backrest mounting frame 2 is located above the seat 1, and the backrest 3 is mounted on the backrest mounting frame 2. The chair back mounting frame 2 is of a thin-sheet structure, and the chair back mounting frame 2 surrounds the chair back 3 from the rear to the front of the chair back 3. The back of the chair 3 passes through flexible connectors 8 to be fixed on back of the chair mounting bracket 2, and the back of the chair 3 is located the place ahead of back of the chair mounting bracket 2, and the back of the chair 3 is fixed to flexible connectors 8's one end, and the other end is fixed on back of the chair mounting bracket 2. The flexible connecting piece 8 is a rubber block, and the chair back 3 can swing freely relative to the chair back mounting frame 2 through the flexible connecting piece 8 to adjust a proper supporting position. The number of the chair backs 3 can be two, three or four or more, and the chair backs are sequentially distributed on the chair back mounting frames 2 in the transverse direction. In the present embodiment, the number of the seat backs 3 is two, and the seat backs are arranged symmetrically left and right.

As shown in fig. 1, two ends of the chair back mounting frame 2 are respectively connected with the armrest mounting frames 4 at the corresponding ends through a sliding structure, so that the chair back mounting frame 2 moves back and forth relative to the chair seat 1. The connecting position of the end part of the chair back mounting frame 2 and the handrail mounting frame 4 is positioned at the middle position of the handrail mounting frame 4. Since the chair back mounting frame 2 and the handrail mounting frame 4 are both of a thin-sheet structure and are connected with each other, linkage stress is formed. When the armrest mounting rack 4 is forced to expand outwards, the armrest mounting rack 4 pulls the two ends of the chair back mounting rack 2, so that the chair back mounting rack 2 deforms towards the unfolding direction, and the position of the chair back 3 moves forwards, so that the supporting effect is achieved at the rear of a user. When the user leaned on the back of the chair 3 backward, the crooked degree of handrail mounting bracket 4 increased, and there is the trend that is close to each other at the both ends of handrail mounting bracket 4 to drive two handrail mounting brackets 4 and draw close each other, form littleer encirclement, thereby play the supporting role in the user left and right sides.

As shown in fig. 1, the sliding structure includes a sliding groove 21, a sliding block 6 and an adjusting and locking member 7, the sliding groove 21 is disposed on the chair back mounting frame 2, the sliding block 6 is fixedly mounted on the armrest mounting frame 4, and the adjusting and locking member 7 is screwed on the sliding block 6 and clamped on the left and right sides of the chair back mounting frame 2 together with the sliding block 6. The adjusting locking piece 7 comprises a clamping block and a screw rod, the screw rod is fixedly connected with the clamping block, the screw rod penetrates through the sliding groove 21 and then is in threaded connection with the sliding block 6, and the handrail mounting frame 4 is clamped between the clamping block and the chair back mounting frame 2.

The sliding groove 21 is an inclined long groove, the height of the front end of the sliding groove 21 is lower than that of the rear end of the sliding groove, and the length direction of the sliding groove 21 and the horizontal direction form an inclined angle of 15-30 degrees. In the present embodiment, the inclination angle is preferably 15 °. The sliding block 6 is of a long strip-shaped structure, the length direction of the sliding block is the same as that of the sliding groove 21, and the sliding block 6 is prevented from rotating in the sliding groove 21 due to the stress of the chair back mounting frame 2.
