Detailed Description

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

As shown in fig. 1-7, the unlocking mechanism of the swing arm locking device of the swing dining chair comprises a support frame 1, a swing arm 2 and a seat body 3, wherein the swing arm 2 is rotatably connected with the support frame 1, and a locking device 4 is arranged between the swing arm 2 and the support frame 1. The locking device 4 is used for locking the swing arm 2 to be fixed relative to the support frame 1, and in particular, when the swing dining chair is used as a dining chair, the locking device 4 is required to be in a locking state, and the swing arm 2 cannot swing relative to the support frame 1 at the moment so as to ensure the use safety; when the swing chair is used as a swing, the locking device 4 is in an unlocked state, and the swing arm 2 can swing relative to the support frame 1.

The locking device 4 comprises a trigger button 44, which trigger button 44, when pressed, unlocks the locking device 4. Locking device 4 still includes lock shell 41, lock seat 42 and spring bolt 43, and lock shell 41 fixed mounting is in the bottom of swing arm 2, and lock seat 42 rotates to be connected in the bottom of support frame 1, and spring bolt 43 sets up in lock shell 41 along horizontal activity, and lock seat 42 is equipped with the lockhole 421 that supplies spring bolt 43 to go into, specifically speaking, the one end of spring bolt 43 that is close to lock seat 42 is protruding to be equipped with lockhole 421 complex locking post 431.

The locking tongue 43 is provided with a second return spring, and the second return spring is used for enabling the locking tongue 43 to have a movement tendency of being clamped into the locking hole 421; the trigger button 44 is movably arranged in the lock case 41 along the longitudinal direction, the upper end of the trigger button 44 is in linkage fit with the unlocking button 6, and the lower end of the trigger button 44 is in linkage fit with the bolt 43. The bolt 43 is provided with a bolt inclined surface 432, and the lower end of the trigger button 44 is provided with a button inclined surface 441 which is matched with the bolt inclined surface 432 in an abutting mode.

When the locking column 431 of the bolt 43 is clamped in the locking hole 421, the lock case 41 is connected with the lock base 42, the locking device 4 is in a locking state, and the swing arm 2 cannot swing relative to the support frame 1; when the trigger button 44 is pressed to move downward relative to the lock case 41, the button inclined surface 441 pushes against the latch inclined surface 432, so that the latch 43 slides laterally, and at this time, the locking column 431 of the latch 43 is disengaged from the lock hole 421, thereby unlocking the locking device 4.

In order to facilitate the locking column 431 to be separated from the lock seat 42 after being separated from the lock hole 421, a sliding slot 422 for the locking column 431 to slide out of the lock seat 42 is arranged beside the lock hole 421, the lock hole 421 is located at the inner end of the sliding slot 422, the depth of the lock hole 421 is deeper than that of the sliding slot 422, and the outer end of the sliding slot 422 penetrates through the side wall of the lock seat 42. When the locking post 431 is disengaged from the locking hole 421, the locking post 431 slides into the sliding slot 422, and the user pulls the lock case 41 and the lock seat 42 to disengage the locking post 431 from the lock seat 42.

The lock shell 41 is provided with a mounting hole 411 for installing the trigger button 44, the trigger button 44 is hidden in the mounting hole 411, and the hidden mounting structure is adopted for the trigger button 44, so that the possibility of misoperation can be effectively avoided, and the safety is further improved.

The swing arm 2 is provided with a lifting seat 5, the lifting seat 5 can slide relative to the swing arm 2, and the locking device 4 is positioned on the sliding track of the lifting seat 5; seat body 3 is pivotally connected to riser 5, and seat body 3 can rotate between first angular position and second angular position relative to riser 5, specifically speaking, when seat body 3 is in the first angular position, the swing dining chair is in the dining chair state, and when seat body 3 is in the second angular position, the swing dining chair is in the swing state.

The lifting seat 5 is movably provided with an unlocking button 6 which is in linkage fit with the trigger button 44, and the seat body 3 is provided with an arc-shaped part 31 which is in linkage fit with the unlocking button 6. Arc portion 31 adopts the integrated into one piece structure for the shaping in the arc of seat main part 3 outer wall, is favorable to practicing thrift the cost, and the installation is more convenient. The arc portion 31 is located obliquely below the pivot point of the seat body 3 and the lifter base 5, and ensures that the arc portion 31 can touch the unlock button 6 when the seat body 3 pivots. The center of arc portion 31 is eccentric settings for seat body 3 and the pivot of going up and down seat 5, and arc portion 31 adopts eccentric settings for seat body 3 is when changeing to the second angular position by first angular position, and arc portion 31 can be used to unlock button 6, and when seat body 3 changes to first angular position by the second angular position, arc portion 31 then can not be used to unlock button 6. A first return spring which is matched with the unlocking button 6 in an abutting mode is arranged in the lifting seat 5.

When the seat body 3 is adjusted from the first angular position to the second angular position, the arc portion 31 pushes the unlocking button 6 to slide downward along the lifting seat 5, so that the unlocking button 6 is located at a position where the trigger button 44 can be pressed. When the seat body 3 is adjusted from the second angular position to the first angular position, the first return spring drives the unlock button 6 to return.

In this embodiment, the unlock button 6 includes the first pole portion 61 and the second pole portion 62 that are connected, is equipped with the slide 51 with first pole portion 61 sliding fit in the lift seat 5, and a reset spring supports and locates between lift seat 5 and the first pole portion 61, and first pole portion 61 cooperates with the linkage of trigger button 44, and second pole portion 62 stretches out lift seat 5, and arc portion 31 cooperates with the linkage of second pole portion 62.

In order to improve the motion stability of the unlocking button 6, a guide post 52 is arranged in the slide 51, and the first rod part 61 is provided with a kidney-shaped hole 611 matched with the guide post 52.

The length of the slideway 51 is adapted to the length of the first rod part 61; when the seat body 3 is located at the first angular position, the first rod part 61 is hidden in the slide way 51; when the seat main body 3 is located at the second angular position, the end of the first lever portion 61 protrudes out of the slide 51. Through adopting above-mentioned structural design, when the swing dining chair was used as the dining chair, the unblock end of unblock button 6 can be in hidden state, has further prevented the possibility of maloperation like this, more is favorable to safe in utilization.

The working principle of the present invention is described in detail as follows: when the seat body 3 is adjusted from the first angular position to the second angular position (i.e. the swing dining chair is adjusted from the dining chair state to the swing state), during the process, the seat body 3 will rotate relative to the lifting seat 5, the arc portion 31 will abut against the second rod portion 62, the second rod portion 62 will drive the first rod portion 61 to move downwards along the lifting seat 5, so that the trigger button 44 is pressed against the lifting base 5, at which time the lifting base 5 is slid downwards, when the unlocking end (i.e., the lower end) of the second lever part 62 contacts the trigger button 44, the trigger button 44 is moved downward by the pushing force of the second lever part 62, therefore, the latch 43 is driven to move, and the lock column 431 of the latch 43 is also separated from the lock hole 421 and slides into the sliding groove 422, at this time, the user pulls the lock case 41 and the lock base 42, so that the lock column 431 can be separated from the lock base 42, and the unlocking of the locking device 4 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.
