Furthermore, a raised baffle is arranged in the middle of the rotary seat, a slot corresponding to the baffle is arranged on the control piece, and the baffle is used for limiting the maximum stroke of the control piece; the blocking plate can limit the control member in the jack and can only move relatively axially in the jack.

Further, the symmetry sets up two arc joint portions on the outer wall of swivel mount, the symmetry be provided with on the outer wall of control seat two with arc joint portion assorted joint grooves, two arc joint portions correspond and put into at two joint inslots, make swivel mount, control seat ability synchronous rotation.

Further, the rotary seat and the control seat are locked together through screws.

The utility model has the advantages that: the angle of handrail can be adjusted, can adapt to different crowds and use under different scenes, and the handrail can carry out better support to human hand, and the travelling comfort is good, application scope is wide, and this product structural design is reasonable, simple easy operation.

Detailed Description

Referring to fig. 1 to 7, a rotatable armrest assembly includes a seat frame 2 having a shaft hole 1 on a side surface thereof, a swivel mount 3 installed in the shaft hole 1 and rotatably connected to the seat frame 2, a control seat 5 connected to the swivel mount 3 and having a T-shaped jack 4 on a side surface thereof, and an armrest 6 connected to the control seat 5, wherein a plurality of limiting grooves 7 are formed in an inner wall of the shaft hole 1, a T-shaped control member 8 capable of linearly moving in a radial direction is installed in the jack 4, a return elastic member 9, preferably a return spring, is installed between one end of the control member 8 and an inner wall of a corresponding end of the control seat 5, one end of the return spring is placed in a spring groove 18 formed in the control member 8, and the other end thereof is fitted over a spring connector 19 formed in an inner wall of the control seat 5, thereby preventing the return spring from falling off; the control member 8 is provided with a protrusion 10 which can be matched with each limit groove 7 and is used for limiting the rotation of the control seat 5 and the rotary seat 3.

The rotary seat 3 passes through the shaft hole 1 through the connecting piece 11 and then is connected with the seat frame 2, and the connecting piece 11 and the rotary seat 3 can synchronously rotate; preferably, the connecting member 11 is a screw, and the screw is sleeved on the flat pad 12 and the spring pad 13 in sequence, and is threaded with the rotary seat 3 after passing through the shaft hole 1.

A raised baffle plate 14 is arranged in the middle of the rotary seat 3, a slot 15 corresponding to the baffle plate 14 is arranged on the control member 8, the width of the slot 15 is larger than the thickness of the baffle plate 14, and the baffle plate 14 is used for limiting the maximum stroke of the control member 8.

Two arc joint portions 16 are symmetrically arranged on the outer wall of the rotary seat 3, two joint grooves 17 matched with the arc joint portions 16 are symmetrically arranged on the outer wall of the control seat 5, the two arc joint portions 16 are correspondingly arranged in the two joint grooves 17, and then the rotary seat 3 and the control seat 5 are locked together through screws.

The working principle is as follows: in a free state, under the action of the return elastic element 9, the control element 8 has its protrusion 10 placed in one of the limiting grooves 7 on the seat frame 2, and at this time, the armrest 6, the swivel base 3, and the control seat 5 are not rotatable. When the angle of the armrest 6 is to be adjusted, the control element 8 is pressed first, the control element 8 and the reset elastic element 9 move backwards in a straight line, and the bulge 10 of the control element 8 leaves the limiting groove 7 and enters the inner cavity of the control seat 5, at the moment, the armrest 6 is rotated, the armrest 6 drives the control seat 5 and the rotary seat 3 to rotate synchronously, when the second limiting groove 7 is reached, the bulge 10 on the control element 8 automatically slides into the second limiting groove 7 under the reaction force of the reset elastic element 9, at the moment, the armrest 6, the rotary seat 3 and the control seat 5 cannot rotate, and the angle adjustment of the armrest 6 is completed simultaneously. The limiting groove 7 can be a plurality of limiting grooves, and the handrail 6 can realize different angle adjustment by placing the convex parts 10 on the control piece 8 into different limiting grooves 7.

According to the above description and the specific embodiments, the present invention is not limited to the above-described specific embodiments, and some modifications and variations of the present invention should fall within the protection scope of the claims of the present invention.
