Detailed Implementation

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0040] See Figures 1 to 13 As shown, a child chair includes a support frame 1, with two sets of uprights 12 extending from the support frame 1. A seat 4 is rotatably mounted between the two sets of uprights 12. A connecting piece 43 is provided on the seat 4 or the support frame 1 to control the relative fixation between the support frame 1 and the seat 4. The support frame 1 includes a base 11, with the uprights 12 respectively fixedly mounted on the base 11. An auxiliary connecting rod 2 is detachably mounted between the uprights 12. The auxiliary connecting rod 2 is located above the base 11 and below the seat 4, and has two supporting walls 23. The two supporting walls 23 abut against the opposite sides of the two sets of uprights 12. In this structure, since the two supporting walls 23 on the auxiliary connecting rod 2 abut against the opposite sides of the two sets of uprights 12, the auxiliary connecting rod 2 can support the two sets of uprights 12 during use, preventing the upper ends of the two sets of uprights 12 from tilting and converging during use. This helps improve the stability of the child chair structure and facilitates the relative rotation of the seat 4 and the uprights 12 during use, making it convenient for the user.

[0041] In this utility model, the support wall 23 extends to form an installation part 22, and the upright 12 is provided with an installation groove 122 adapted to the installation part 22. One side of the installation groove 122 extends to the front or rear side of the upright 12 and forms a first opening 1221. The support wall 23 can pass through the first opening 1221 into the installation groove 122 and abut against the end of the installation groove 122. The setting of the first opening 1221 facilitates the quick disassembly and installation of the installation part 22 and the installation groove 122. During the disassembly and installation process, it is not necessary to disassemble the two uprights 12 relative to each other, which facilitates the disassembly and installation of the auxiliary connecting rod 2.

[0042] Preferably, one side of the mounting groove 122 is inclined toward the upper side of the upright 12 to form the first opening 1221. In this structure, the auxiliary connecting rod 2 is less likely to accidentally connect with the mounting groove 122 during installation, which facilitates the stable installation of the auxiliary connecting rod 2.

[0043] A locking member 3 is detachably provided on the mounting part 22. The mounting groove 122 passes through the upright 12, and a positioning part 1222 adapted to the locking member 3 is provided in the mounting groove 122.

The setting of the locking member 3 and the positioning part 1222 is conducive to the stable installation of the auxiliary link 2, preventing the mounting part 22 from moving in the mounting groove 122, and preventing the auxiliary link 2 from accidentally detaching from the upright 12.

[0044] In this embodiment, the positioning part 1222 is located on one side of the lower end of the mounting groove 122. When the auxiliary connecting rod 2 is installed, the mounting part 22 will enter the positioning part 1222 under the action of gravity. The locking part 3 is provided with a protrusion 31 that is adapted to the positioning part 1222. The protrusion 31 is provided with a threaded hole 32 that is adapted to the mounting protrusion.

[0045] The auxiliary connecting rod 2 described in this utility model includes a U-shaped connecting rod body 21, with support walls 23 disposed on the sides at both ends of the connecting rod body 21. The U-shaped connecting rod body 21 facilitates small-amplitude deformation of the auxiliary connecting rod 2, thereby allowing the two support walls 23 on the auxiliary connecting rod 2 to pass between the two uprights 12, which facilitates the installation of the auxiliary connecting rod 2 and reduces the occurrence of situations where the auxiliary connecting rod 2 cannot be installed due to production errors. In this embodiment, the U-shaped connecting rod body 21 is bent downwards. During use, this structure can avoid interference between the seat 4 and the auxiliary connecting rod 2, and facilitate the flexible rotation of the seat 4 and the support frame 1.

[0046] Each of the two sets of uprights 12 has a suspension block 123 rotatably mounted on one side opposite to the other. The seat 4 has a hook groove 421 adapted to the suspension block 123. The seat 4 also has a snap-fit ​​block 44 and a first elastic element 45 movably mounted on it. The first elastic element 45 can drive the snap-fit ​​block 44 to be fixed relative to the suspension block 123 and make the seat 4 and the suspension block 123 rotate synchronously. Under the action of external force, the snap-fit ​​block 44 can be displaced, so that the hook groove 421 and the suspension block 123 can be detached relative to each other. The hook groove 421 and the suspension block 123 facilitate the quick connection between the seat 4 and the two sets of uprights 12. The snap-fit ​​block 44 and the first elastic element 45 facilitate the stable installation of the hook groove 421 and the suspension block 123, avoid accidental disassembly of the seat 4 and the uprights 12 during use, and facilitate the disassembly of the seat 4 and the uprights 12, as well as the disassembly of the child chair.

[0047] In this embodiment, the cross-section of the suspension block 123 is T-shaped, and the hook groove 421 is a T-shaped groove adapted to the suspension block 123.

[0048] The hook groove 421 has a sliding groove 422 on its side. The locking block 44 is slidably disposed in the sliding groove 422. The locking block 44 has a locking part 441. The hanging block 123 has a locking hole 124 on its side that matches the locking part 441. The hook groove 421 has a second opening 423 for the hanging block 123 to pass through. The locking part 441 has a guide surface 442 on the side near the second opening 423. The hanging block 123 can abut against the guide surface 442. The engaging part 441 is driven to retract into the slide groove 422, thereby engaging the engaging part 441 with the engaging hole 124. The engaging part 441, which is inserted into the hook groove 421, is not easily contacted by accident and is not easily damaged by other items during storage and transportation, which facilitates the storage and transportation of the child chair. The guide surface 442 facilitates the automatic engagement of the engaging part 441 with the engaging hole 124, and facilitates the quick connection and engagement of the hook groove 421 with the hanging block 123, which facilitates the quick assembly of the child chair.
