The tube 21 is locked against the support tube 22, and can be released to fold the baby chair 2. In addition, an external connecting piece 26 is also arranged near the front tube 21 of the seat, and the external connecting piece 26 is detachably connected with the Frame body 1 assembly connection. The roof fixing strip 24 is pivotally connected to the lower end of the backing support tube 22 through the roof fixing seat 23 . Preferably, the baby chair 2 disclosed in this embodiment also includes a calf rest adjustment group, the calf rest adjustment group includes a calf rest connecting seat 27 and a calf rest bar 28, and the calf rest connecting seat 27 is arranged on the The upper end of the seat front tube 21, the calf leaning rod 28 is pivotally connected to the calf leaning connecting seat 27, and the calf leaning rod 28 and the calf leaning rod 28 can be selectively adjusted by turning the calf leaning rod 28. The included angle of the lower leg rest connecting seat 27 is therefore the user can change the angle of the lower leg rest bar 28 according to the needs of the young child, so that the young child can have a more comfortable riding experience.

Specifically, the upper end of the seat front tube 21 is fixed with a connecting piece 211, and the upper end of the connecting piece 211 is provided with an engaging hole 211a. The lower end of the back support tube 22 is fixed with a pivot member 221, and the pivot member 221 is provided with a receiving groove 221a, the connecting member 211 is pivotally connected to the pivot member 221, and part of the connection The component 211 is accommodated in the receiving groove 221a. The engaging hole 211a is used to detachably engage with the folding mechanism 25, that is, when the folding mechanism 25 is engaged in the engaging hole 211a, the baby chair 2 is locked, and when the folding mechanism 25 disengages from the engaging hole When 211a, unlocking is realized, and the baby chair 2 can be folded. The roof fixing strip 24 is pivotally connected to the connecting member 211 through the roof fixing seat 23 . More specifically, there are two ceiling fixing seats 23 and they are respectively pivotally connected to the outer sides of the two connecting members 211 .

As shown in Figures 5-10, the folding mechanism 25 is arranged at the lower end of the backing support tube 22, and the folding mechanism 25 is telescopically arranged in the backing support tube 22, and is connected with the card The engaging hole 211a is detachably engaged. Specifically, the folding mechanism 25 includes a locking rod 251 , an elastic member 252 , pins 253 a , 253 b , a traction member 254 and a folding operation member 255 . The lower end of the locking rod 251 is provided with an engaging end 251a, and the engaging end 251a is telescopically engaged in the engaging hole 211a, so that the locking rod 251 and the connecting piece 211 can be separated. mutual engagement. The locking rod 251 is also provided with two sliding grooves 251b, 251c along its length direction, and the outer periphery of the locking rod 251 is located between the two sliding grooves 251b, 251c, and protrudes outwards with a conflicting portion 251d. When connecting, the two bolts 253a, 253b are respectively inserted in the two sliding grooves 251b, 251c, and are respectively connected to the back support tube 22; the elastic member 252 is sleeved on the outer periphery of the locking rod 251 , and one end of the elastic member 252 is in contact with the contact portion 251d, and the other end of the elastic member 252 is in contact with the pin 253b. The traction piece 254 is arranged in the back support tube 22, and one end of the traction piece 254 is fixed on the upper end of the locking rod 251, and the other end is fixed on the upper end of the back support tube 22 for the folding operation. Part 255 on. Therefore, by operating the retractable operating member 255, the traction member 254 can be driven to pull the locking rod 251 to slide against the support tube 22. During the sliding process of the locking rod 251 along the pulling direction, the elastic member 252 is compressed and resists the Between the above-mentioned conflicting portion 251d and the latch 253b; after the retractable operating member 255 is released, the restoring force generated by the elastic member 252 resets the locking pull rod 251 .

Preferably, the back support tube 22 is further provided with two through holes 222, and the two pins 253a, 253b are inserted into the two through holes 222 respectively. Moreover, in the present invention, the elastic member 252 is a spring. Of course, the elastic member 252 is not limited to a spring, and it can also be a common component with elastic restoring force in the technical field.

As shown in FIGS. 8-10 , the folding operation member 255 includes a connecting portion 255a, and the connecting portion 255a is provided with a pivot hole 255b and several connecting holes 255c, and the several connecting holes 255c are all around the pivot joint. The axis of the hole 255b rotates. In this embodiment, there are two connecting holes 255c, which are symmetrically arranged on both sides of the pivoting hole 255b; The side has a folding operation part 255d formed by bending and extending; the folding operation part 255 is rotatably connected to the back support tube 22 through the pivot hole 255b, and the folding operation part 255d faces the back support tube 22 pivots on the outside, and the two connecting holes 255c are respectively used to connect with the pulling members 254 on both sides. Therefore, turning the folding operation part 255d in the direction of the arrow in FIG. 10 can make the connecting part 255a rotate, thereby pulling the traction member 254 to drive the locking rod 251 to slide, and then make the folding mechanism 25 disengage from the engaging hole 211a , to achieve unlocking.

As shown in Figures 1-11, the folding process of the baby chair 2 of the present invention will be described.

When the baby chair 2 is folded, the folding operation part 255d is pushed, and the connecting part 255a of the folding operation part 255 is rotated, so that the traction part 254 is driven to pull the locking pull rod 251, so that the engaging end 251a Disengage from the engaging hole 211a, so that the locking rod 251 is separated from the connecting piece 211, and then push the back support tube 22 to rotate around the pivot point between the seat front tube 21, that is The folding of the back support tube 22 can be realized, thereby realizing the folding of the baby chair 2 , and the folded baby chair 2 is shown in FIG. 11 .

Since the baby chair 2 of the present invention includes a seat front tube 21, a backrest support tube 22 and a folding mechanism 25, the upper end of the seat front tube 21 is pivotally connected to the lower end of the backrest support tube 22, so The folding mechanism 25 is arranged between the backrest support tube 22 and the seat front tube 21 to lock and release the backrest support tube 22 and the seat front tube 21. , after the folding mechanism 25 is released, the back support tube 22 and the seat front tube 21 can be folded, and the baby chair 2 is detachably installed inside the frame body 1 of the baby carrier , so the entire frame body 1 can be folded after it is folded inside the frame body 1, or the baby chair 2 can be disassembled from the frame body 1 and then the baby chair 2 and the frame body can be folded separately Body 1, easy to use, and also greatly reduces the occupied indoor space.

What is disclosed above is only a preferred embodiment of the present invention, and of course it cannot limit the scope of rights of the present invention. Therefore, equivalent changes made according to the patent scope of the present invention still fall within the scope of the present invention.
