By adopting a hidden installation structure for the trigger button 114, the possibility of misoperation can be effectively avoided, and the safety is further improved.

The lifting seat 5 is provided with a second unlocking mechanism for unlocking the fourth locking device, the second unlocking mechanism is in linkage fit with the seat part 21, and when the seat part 21 is adjusted from the first angle position to the second angle position relative to the lifting seat 5, the seat part 21 drives the second unlocking mechanism to act.

Specifically speaking, the second unlocking mechanism includes that the activity sets up in going up and down seat 5 and with trigger button 114 linkage complex unlock button 121, set up in seat 21 and with unlock button 121 linkage complex arc portion 214, arc portion 214 adopts the integrated into one piece structure for the arc of shaping in seat main part 2 outer wall, is favorable to practicing thrift the cost, and the installation is more convenient. The arc portion 214 is located obliquely below the pivot point of the seat body 2 and the liftable seat 5, and ensures that the arc portion 214 can touch the unlock button 121 when the seat body 2 pivots.

The unlocking button 121 includes a first rod 1211 and a second rod 1212 connected to each other, a slide 53 slidably engaged with the first rod 1211 is disposed in the lifting seat 5, the first return spring is abutted between the lifting seat 5 and the first rod 1211, the first rod 1211 is in linkage engagement with the trigger button 114, the second rod 1212 extends out of the lifting seat 5, and the arc portion 214 is in linkage engagement with the second rod 1212.

The length of the slide 53 is adapted to the length of the first rod 1211; when the seat body 2 is located at the first angular position, the first rod 1211 is hidden in the slide 53; when the seat main body 2 is located at the second angular position, the end of the first rod portion 1211 protrudes out of the slide 53. Through adopting above-mentioned structural design, when the swing dining chair was used as the dining chair, the unblock end of unblock button 121 can be in hidden state, has further prevented the possibility of maloperation like this, more is favorable to safe in utilization.

The center of arc portion 214 is eccentric arrangement for the pivot of seat main part 2 with lift seat 5, and arc portion 214 adopts eccentric arrangement for seat main part 2 is when changeing to the second angular position by first angular position, and arc portion 214 can be used to unlock button 121, and when seat main part 2 changes to first angular position by the second angular position, arc portion 214 then can not be used to unlock button 121.

A second return spring (not shown) is disposed in the lifting seat 5 and is in abutting fit with the unlocking button 121, and the second return spring is used for enabling the unlocking button 121 to have a movement trend away from the trigger button 114 all the time.

When the seat 21 is adjusted from the first angular position to the second angular position, in the process, the seat 21 rotates relative to the lifting base 5, the arc portion 214 abuts against the second rod portion 1212, and the second rod portion 1212 drives the first rod portion 1211 to move downward along the lifting base 5, so that the lifting base 5 is located at a position where the trigger button 114 can be pressed (i.e., the lower end of the first rod portion 1211 extends from the slide 53), at this time, the lifting base 5 slides downward, when the unlocking end (i.e., the lower end) of the second rod portion 1212 contacts the trigger button 114, the trigger button 114 moves downward due to the thrust of the second rod portion 1212, so as to drive the latch 113 to move, and the locking column 1131 of the latch 113 is also separated from the 1121 and slides into the lock base chute 1122, at this time, the user pulls the lock case 111 and the lock base 112, so that the locking column 1131 can be separated from the lock base 112, and the unlocking of the locking device is completed.

The above is only the preferred embodiment of the present invention, so all the equivalent changes or modifications made by the structure, features and principles in accordance with the claims of the present invention are included in the claims of the present invention.
