Existing child seats, such as the one described in Chinese Patent No. ZL201720692187.5, have the following structure: a child seat, multiple legs, and a set of sliding panels; the child seat includes a cushion, a backrest behind the cushion, and a front accessory located in front of the backrest, forming a side enclosure between the backrest and the front accessory to protect the child sitting on the cushion; the front accessory is a shelf or a front side rail. In this patent, the child seat is a single piece, cannot be disassembled, takes up a large area, and is very inconvenient to transport and store. Summary of the Invention
[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a foldable child seat that is convenient for transportation and storage.
[0004] The objective of this utility model can be achieved through the following technical solution: A foldable child seat includes a seat body, a backrest, and two sets of armrests. The backrest is hinged to the seat body, and the two sets of armrests are located on both sides of the backrest. Both sets of armrests are hinged to the seat body. A handle is movably provided on the backrest, and both ends of the handle are connected to locking blocks via connecting strips. Each set of armrests has a locking hole, and the end of the locking block is located in the locking hole, positioning the armrests and the backrest in the use state. Pulling up the handle causes the handle to drive the two locking blocks to move relative to each other via the connecting strips, causing the locking blocks to disengage from the locking holes. At this time, the backrest and the two sets of armrests can be rotated.
[0005] In the aforementioned foldable child seat, the locking block includes a locking protrusion and a connecting shaft. The diameter of the locking protrusion is larger than the diameter of the connecting shaft. A first spring is sleeved on the connecting shaft. A baffle is provided on the backrest. The two ends of the first spring contact the side of the baffle and the locking protrusion, respectively. The end of the locking protrusion is located in the locking hole. When the handle is pulled up, the two locking blocks move relative to each other, and the first spring is compressed. After the handle is released, the spring force of the first spring is released, which drives the locking block, the connecting bar, and the handle to reset.
[0006] In the aforementioned foldable child seat, the locking block further includes an I-shaped connecting block. The locking protrusion and the I-shaped connecting block are located at both ends of the connecting shaft, the I-shaped connecting block passes through the baffle, and the end of the connecting strip is provided with an mounting protrusion. The mounting protrusion has an I-shaped groove, and the I-shaped connecting block is inserted into the I-shaped groove to make the locking block and the connecting strip connected in an I-shape.
[0007] In the aforementioned foldable child seat, the connecting strip is arc-shaped, and two connecting strips are distributed in a figure-eight shape at both ends of the bottom surface of the handle. The backrest includes a first back panel and a second back panel, which are installed opposite to each other. The first back panel is provided with two sets of guide blocks, and the guide blocks have arc-shaped guide grooves. The middle part of the connecting strip is movably located in the guide groove. The second back panel is provided with two sets of arc-shaped positioning blocks, and the positioning blocks are in contact with the connecting strip.
[0008] In the aforementioned foldable child seat, both the first back panel and the second back panel are provided with guide blocks to guide the movement of the handle. The backrest has a handle hole, and the handle has a pull hole. The pull hole and the handle hole are connected, and part of the handle protrudes from the handle hole.

A gear is provided between the first tooth groove and the second tooth groove. The gear can move between the first tooth groove and the second tooth groove and meshes with the first tooth groove and the second tooth groove. A second spring is provided in the first tooth groove to abut against the gear. Both ends of the footrest are provided with button grooves, and a button is movably installed in each of the two button grooves. The button is provided with an abutting block, which passes through the bottom of the button groove and abuts against the gear.
[0010] In the aforementioned foldable child seat, pressing the two buttons causes the gear to disengage from the first tooth groove and engage only with the second tooth groove via the abutment block, compressing the second spring and allowing the foot pedal to rotate. Releasing the buttons releases the spring force of the second spring, causing the gear to reset and engage with both the first and second tooth grooves simultaneously, and the buttons also reset synchronously. At this point, the foot pedal is locked and cannot rotate.
[0011] In the aforementioned foldable child seat, the bottom of the seat body is also equipped with several support feet, each support foot including an upper support rod and a lower support rod. The top of the lower support rod has an insertion block, which is inserted into the hollow upper support rod.

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0022] As shown in Figures 1-5, this foldable child seat includes a seat body 1, a backrest 2, and two sets of armrests 3. The backrest 2 is hinged to the seat body 1, and the two sets of armrests 3 are located on both sides of the backrest 2, both of which are hinged to the seat body 1. A handle 4 is movably mounted on the backrest 2, and both ends of the handle 4 are connected to locking blocks 6 via connecting strips 5. Each set of armrests 3 has a locking hole 31, and the end of the locking block 6 is located within the locking hole 31, positioning the armrests 3 and the backrest 2 in the use state. Pulling up the handle 4 causes the handle 4 to move the two locking blocks 6 relative to each other via the connecting strips 5, disengaging the locking blocks 6 from the locking holes 31, thus unlocking the backrest 2 and the armrests 3. Rotating the backrest 2 folds it so that it is laterally positioned on the seat body 1, and rotating the two sets of armrests 3 relative to each other folds them so that they are laterally positioned on the folded backrest 2, completing the folding of the backrest 2 and the armrests 3.
[0023] In the above technical solution: the locking block 6 includes a locking protrusion 61 and a connecting shaft 62. The diameter of the locking protrusion 61 is larger than the diameter of the connecting shaft 62, and a first spring 64 is sleeved on the connecting shaft 62. As shown in Figure 5, a baffle 26 is provided on the backrest 2, and the two ends of the first spring 64 are in contact with the sides of the baffle 26 and the locking protrusion 61, respectively. Specifically, the end of the locking protrusion 61 is located in the locking hole 31. When the handle 4 is pulled up, the two locking blocks 6 move relative to each other, and the first spring 64 is compressed. After the handle 4 is released, the elastic force of the first spring 64 is released, which drives the locking block 6, the connecting bar 5 and the handle 4 to reset.
[0024] In the above technical solution: the locking block 6 also includes an I-beam connecting block 63. The locking protrusion 61 and the I-beam connecting block 63 are located at both ends of the connecting shaft 62 respectively. The I-beam connecting block 63 passes through the baffle 26. The end of the connecting strip 5 is provided with an mounting protrusion 51. An I-beam groove is made on the mounting protrusion 51. The I-beam connecting block 63 is inserted into the I-beam groove so that the locking block 6 and the connecting strip 5 are connected in an I-beam manner.
[0025] In the above technical solution: the connecting strip 5 is arc-shaped, and two connecting strips 5 are distributed in a figure-eight pattern at both ends of the bottom surface of the handle 4. The backrest 2 includes a first back plate 21 and a second back plate 22, which are installed opposite to each other. The first back plate 21 is provided with two sets of guide blocks 23, and the guide blocks 23 have arc-shaped guide grooves, in which the middle part of the connecting strip 5 is movably located. The second back plate 22 is provided with two sets of arc-shaped positioning blocks 24, which contact the connecting strip 5 to prevent the connecting strip 5 from disengaging from the guide groove.
[0026] In the above technical solution: both the first back plate 21 and the second back plate 22 are provided with guide blocks to guide the movement of the handle 4. The backrest 2 has a handle hole 25, and the handle 4 has a pull hole 41, which is connected to the handle hole 25. When the first spring 64 is in the extended state, part of the handle 4 is exposed in the handle hole 25, making it easy for a hand to reach into the pull hole 41 and the handle hole 25 and grasp the handle 4 exposed in the handle hole 25 to apply force, causing the handle 4 to move upward; during the upward movement of the handle 4, when the wall of the pull hole 41 contacts the wall of the handle hole 25, the handle 4 stops moving upward, thereby limiting the movement of the handle 4.
[0027] In the above technical solution: Two foot pedal connecting seats 71 are provided at the bottom front end of the seat body 1, and a foot pedal 7 is provided between the two foot pedal connecting seats 71.
