Oblique tenon grooves 16 are opened on the upper and lower sides of the connecting groove 14, and the oblique tenon block 15 can be clamped in the inside of the oblique tenon groove 16.
[0040] When in use, after the support leg 1 and the connecting plate 2 are spliced and fixed, the two support plates 3 can be taken out, and the block 12 at the bottom of the support plate 3 can be inserted into the inside of the slot 13, and then the backrest 4 can be taken out, and the oblique tenon blocks 15 at the upper and lower ends of the backrest 4 are aligned with the oblique tenon groove 16, and then the backrest 4 is knocked to mortise the oblique tenon blocks 15 into the inside of the oblique tenon groove 16, so as to complete the installation of the backrest 4 for children to lean on, wherein the oblique tenon blocks 15 and the oblique tenon groove 16 are connected by an oblique tenon method, so that the backrest 4 and the support plate 3 can be accurately connected to provide stable structural support.
[0041] Reference Figure 2 and Figure 4 The bottom of the seat plate 5 is symmetrically fixedly connected with an armpit tenon block 17, and the top of the connecting plate 2 is provided with an armpit tenon groove 18, and the armpit tenon block 17 can be snapped into the inside of the armpit tenon groove 18.
[0042] During use, after the support leg 1 and the connecting plate 2 are spliced and fixed, the seat plate 5 can be taken out and placed on the top of the connecting plate 2, and the tenon block 17 is aligned with the position of the tenon groove 18, and then the top of the seat plate 5 is knocked to insert the tenon block 17 into the tenon groove 18, so that the seat plate 5 is installed on the top of the connecting plate 2 for the child to sit on, wherein the tenon block 17 and the tenon groove 18 are connected by tenon, which can enhance the firmness of the connection between the tenon block 17 and the tenon groove 18, making it tighter and less likely to loosen when connected.
[0043] Reference Figure 1 and Figure 5 The adjustment component 6 includes a cavity opened inside the supporting leg 1, a fixed block 61 is fixedly connected to one side of the cavity, a threaded rod 62 is rotatably connected to the top of the fixed block 61, a rotating rod 63 is rotatably connected to one side of the supporting leg 1, a knob 64 is fixedly connected to one end of the rotating rod 63, a bevel gear 1 65 is fixedly connected to the knob 64, a bevel gear 2 66 is fixedly connected to the threaded rod 62, the bevel gear 1 65 is meshed with the bevel gear 2 66, a threaded sleeve 67 is symmetrically threadedly connected to the threaded rod 62, and an auxiliary support leg 68 is fixedly connected to one side of the threaded sleeve 67.
[0044] During use, if the seat height is found to be inappropriate, the knob 64 can be turned to drive the rotating rod 63 to rotate, thereby driving the bevel gear 1 65 to rotate together. Because the bevel gear 1 65 is meshed with the bevel gear 2 66, when the bevel gear 1 65 rotates, the bevel gear 2 66 will be driven to rotate together, and the threaded rod 62 will be driven to rotate by the rotation of the bevel gear 2 66. When the threaded rod 62 rotates, the two threaded sleeves 67 will be driven to gradually descend on the threaded rod 62, so that the auxiliary support leg 68 is gradually extended from the bottom of the cavity under the guidance of the cavity. In this way, by adjusting the extended length of the auxiliary support leg 68, the height of the seat can be quickly adjusted, so that the seat can be adapted to different children, greatly improving the practicality and convenience of the seat.
[0045] The implementation principle of the child seat with a splicing structure in this embodiment is as follows: when in use, first take out the four support legs 1, then take out the multiple connecting plates 2, and gently knock the dovetail blocks 8 at both ends of the connecting plates 2 into the inside of the dovetail groove 7 with a hammer to complete the mortise and tenon joint. Because the dovetail groove 7 and the dovetail block 8 are both dovetail-shaped, high-strength joints can be made between the corners to avoid disengagement when subjected to force, so that the four support legs 1 can be spliced and fixed through the multiple connecting plates 2, and then take out the multiple trapezoidal blocks 10, and respectively mortise and tenon the two ends of the trapezoidal blocks 10 into the inside of the trapezoidal groove 9, and make the sliding groove 11 fit with one corner of the support leg 1, so that a triangle is formed between the trapezoidal block 10 and the two connecting plates 2. According to the principle that the triangle has stability, the trapezoidal block 10 can support the multiple connecting plates 2, thereby greatly improving the stability of the seat, avoiding the seat from shaking, and making the seat more durable;
[0046] Secondly, take out two support plates 3, insert the card block 12 at the bottom of the support plate 3 into the card slot 13, then take out the backrest 4, align the oblique tenon blocks 15 at the upper and lower ends of the backrest 4 with the oblique tenon grooves 16, then knock the backrest 4 to mortise the oblique tenon blocks 15 into the oblique tenon grooves 16, so as to complete the installation of the backrest 4 for the child to lean on, wherein the oblique tenon blocks 15 and the oblique tenon grooves 16 are connected by oblique tenons, so that the backrest 4 and the support plate 3 can be accurately connected to provide stable structural support, and then the seat plate 5 is placed on the top of the connecting plate 2, and the armpit tenon blocks 17 are aligned with the armpit tenon grooves 18, then knock the top of the seat board 5, insert the armpit tenon block 17 into the armpit tenon groove 18, so that the seat board 5 is installed on the top of the connecting plate 2 for the child to sit on, wherein the armpit tenon block 17 and the armpit tenon groove 18 are connected by the armpit tenon method, which can enhance the firmness of the combination between the armpit tenon block 17 and the armpit tenon groove 18, and the combination is tighter and not easy to loosen, so as to quickly splice and install a completed child seat, and each connection is connected by the mortise and tenon method instead of the bolt connection, so that the child seat is safer and more durable, and reduces safety hazards;
[0047] In addition, after the child seat is assembled, if the seat height is found to be inappropriate, the knob 64 can be turned to drive the rotating rod 63 to rotate, thereby driving the bevel gear 1 65 to rotate together. Because the bevel gear 1 65 is meshed with the bevel gear 2 66, when the bevel gear 1 65 rotates, the bevel gear 2 66 will be driven to rotate together, and the threaded rod 62 will be driven to rotate by the rotation of the bevel gear 2 66. When the threaded rod 62 rotates, the two threaded sleeves 67 will be driven to gradually descend on the threaded rod 62, so that the auxiliary support leg 68 is gradually extended from the bottom of the cavity under the guidance of the cavity. Therefore, by adjusting the extended length of the auxiliary support leg 68, the height of the seat can be quickly adjusted, so that the seat can be adapted to different children, greatly improving the practicality and convenience of the seat.
