As shown in fig. 1 to 4, a rotation adjusting mechanism of a child seat mainly includes: the seat 1, the chair back 2 and the locking assembly 3, wherein the locking assembly 3 mainly comprises a locking piece 31, an unlocking handle 32, a sliding seat 33, a stay wire 34 and a return spring 35.

The base 1 is provided with a plurality of locking holes 10, the base 1 is provided with at least two locking holes 10 for locking when the chair back 2 is forward and the chair back 2 is reverse, and the chair back 2 can not rotate relative to the base 1 after the locking piece 31 is locked in the corresponding locking hole 10.

The chair back 2 is rotatably arranged on the base 1, the chair back 2 is provided with a rotary table 21 fixedly connected with the rotary table, the main body part of the chair back 2 is made of plastic, the rotary table 21 is made of metal, the strength of the rotary table is improved, and the wear resistance of the rotary table can be improved in the repeated rotary adjustment process.

The locking assembly 3 comprises a locking piece 31 and an unlocking handle 32, wherein the locking piece 31 is movably locked in the locking hole 10, and when the locking piece 31 is locked in the locking hole 10, the chair back 2 is locked on the base 1 and cannot rotate relative to the base 1; when the locking piece 31 is disengaged from the locking hole 10, the seat back 2 is unlocked from the base 1, and the seat back 2 can rotate relative to the base 1. The unlocking handle 32 is rotatably disposed on the chair back 2, and pulling the unlocking handle 32 can drive the locking piece 31 to unlock from the locking hole 10. The unlocking handle 32 includes a rotating portion 321 and a pulling arm 322 protruding outwards along the rotating portion 321, the rotating portion 321 is hinged to the seat back 2 through a rotating pin, and the pulling arm 322 is shaped like an inner handle of a vehicle door, so that the pulling arm 322 is conveniently pulled to perform unlocking actions. Specifically, pulling the pulling arm 322 outwards drives the locking piece 31 to disengage from the locking hole 10.

In actual use, pulling the unlocking handle 32 can unlock the locking piece 31 from the locking hole 10, unlocking is simple, and when pulling the unlocking handle 32, the unlocking handle is similar to the action of a driving door, operation is convenient, and unlocking experience is good.

The locking assembly 3 comprises a sliding seat 33, the sliding seat 33 is slidably arranged on the chair back 2, and the sliding seat 33 can drive the locking piece 31 to move up and down so as to enable the locking piece 31 to be separated from the locking hole 10 or locked into the locking hole 10. When the sliding seat 33 drives the locking piece 31 to move upwards, the locking piece 31 is separated from the locking hole 10, and the chair back 2 is unlocked; when the slide 33 drives the locking piece 31 to move downwards, the locking piece 31 is locked into the locking hole 10, and the chair back 2 is locked on the base 1. Specifically, the sliding seat 33 is provided with a chute 331 disposed obliquely with respect to the sliding direction, the locking piece 31 includes a lock pin 311 and a limiting shaft 312 connected to the lock pin 311, the lock pin 311 and the limiting shaft 312 are mutually perpendicular, the limiting shaft 312 movably penetrates through the chute 331, and the lock pin 311 is movably locked in the locking hole 10. When the slide 33 slides, the position of the limiting shaft 312 in the sliding groove 331 changes, which corresponds to that the limiting shaft 312 slides relative to the sliding groove 331, so that the lock pin 311 is locked into the locking hole 10 or is separated from the locking hole 10.

Wherein, one unlocking handle 32 is respectively arranged along two sides of the chair back 2, and the two unlocking handles 32 are respectively connected with the sliding seat 33 through one stay wire 34. Two sides of the chair back 2 are respectively provided with a fixed seat 22, and an unlocking handle 32 is arranged in the fixed seat 22, so that the unlocking handle 32 is conveniently pulled to perform unlocking action.

In the actual use process, this embodiment can both pull one unlocking handle 32 with one hand and unlock, also can pull two unlocking handles 32 simultaneously with both hands and unlock, namely: can realize that the back 2 is adjusted in the rotation of single hand and the back 2 is adjusted in the rotation of both hands, the unblock is convenient.

A return spring 35 is arranged between the sliding seat 33 and the chair back 2, one end of the return spring 35 is propped against the sliding seat 33, the other end of the return spring 35 is propped against the chair back 2, and when the sliding seat 33 drives the locking piece 31 to be separated from the locking hole 10, the return spring 35 is compressed. When the unlocking handle 32 is released, the sliding seat 33 is restored to the initial position under the action of the elastic force of the return spring 35, and the locking piece 31 is driven to be locked into the locking hole 10 again, so that the chair back 2 is locked on the base 1. Specifically, the chair back 2 has a mounting seat 20 thereon, the sliding seat 33 is slidably mounted on the mounting seat 20, and an end of the return spring 35 away from the sliding seat 33 abuts against the mounting seat 20. The installation seat 20 can ensure the reliable movement of the sliding seat 33, in the actual use process, after the rotation angle of the chair back 2 is adjusted, the return spring 35 drives the sliding seat 33 to return, and the chute 331 obliquely arranged on the sliding seat 33 drives the locking piece 31 to be locked into the locking hole 10 again, so that the chair back 2 is locked on the base 1.

The adjusting principle of the rotary adjusting mechanism is as follows: in the non-operating state, the catch 31 is locked in the catch hole 10, and the seat back 2 is locked to the base 1, and cannot be rotationally adjusted relative to the base 1. When the chair back 2 needs to be rotationally adjusted, one hand or two hands pull the unlocking handle 32 on the same day, the unlocking handle 32 rotates, the stay wire 34 pulls the sliding seat 33, the sliding seat 33 slides, the locking piece 31 moves upwards from the locking hole 10 under the action of the sliding groove 331 and is separated from the locking hole 10, the chair back 2 is unlocked from the base 1, and the reset spring 35 is compressed at the moment. When the rotation of the seat back 2 is completed, the return spring 35 drives the sliding seat 33 to return, the locking piece 31 is locked into the locking hole 10, and the seat back 2 is locked on the base 1.

In this scheme, this rotation regulation mechanism's regulation is convenient, user experience feels good, and can singlehanded or both hands adjust.
