[0013] A vertical guide groove is provided on the side wall of the middle part of the shell, and an unlocking pin slidably matched with the vertical guide groove is connected to the lock block. The shell is also provided with left and right slide grooves arranged along the left and right directions, and an unlocking pull rod is slidably arranged in the left and right slide grooves, and the unlocking pull rod is provided with an oblique hole sleeved on the unlocking pin;

[0014] An unlocking wrench is installed on the seat placement seat, and the unlocking wrench is used to cooperate with the first elastic member to control the displacement of the unlocking pull rod along the left and right slide grooves, thereby driving the locking block to move up and down, thereby realizing the locking and unlocking control of the locking plug.

[0015] Furthermore, two unlocking rods are provided, the two unlocking rods are stacked and arranged left and right, the inclined holes of the two unlocking rods are respectively arranged to be inclined downward outward, and the inclined angles are the same, and unlocking wrenches corresponding to the unlocking rods on the same side are respectively installed on both sides of the seat placement seat.

[0016] Furthermore, the unlocking rod is rotatably installed on the seat placement seat through a reset elastic member, and the unlocking rod is connected to the corresponding unlocking rod through a pull wire. When the unlocking rod is rotated outward, the unlocking rod is pulled outward by the pull wire, thereby driving the locking block to disengage from the lock upward, and the reset elastic member is used to automatically reset the unlocking wrench inward.

[0017] Another object of the present invention is to provide a child seat, comprising the above-mentioned child seat base, wherein a seat body is installed on the seat placement seat of the child seat base.

[0030] like Figure 1-10As shown, the utility model provides a child seat base with a rotating and pulling function, including a base 1, which is provided with a sliding seat 2 arranged to slide left and right, and two guide plates 5 arranged front and back are provided in the middle of the base 1, and a slide groove 20 with openings facing each other is provided between the guide plates 5, and slide rails 6 sliding in the slide grooves 5 on both sides are provided on both sides of the sliding seat 2, and a protrusion 7 is provided on the outer wall of each slide rail 6, and the protrusion 7 is located at the opposite ends of the two slide rails 6, and a limiting member 8 is respectively provided in the end of the slide grooves 5 on both sides, and a limiting member 8 corresponds to the first protrusion 7, and the two limiting members 8 and the corresponding protrusion 7 are arranged on the same side and are located at the opposite ends of the slide grooves 5 on both sides. The limiting members 8 on both sides cooperate with the inner ends of the protrusions 7 on the same side to limit the maximum distance of the sliding seat 2 sliding to both sides to avoid slipping.

[0031] A seat placement seat 3 is rotatably mounted on the sliding seat 2, and a rotation locking structure 4 with an unlocking function is provided between the seat placement seat 3 and the base 1. The rotation locking structure 4 is used to lock the position of the seat placement seat 3 and release the position lock between the seat placement seat 3 and the base 1.

[0032] As a further explanation of this embodiment, the bottom of the seat placement seat 3 is connected to a cover 21 in which the guide plate 5 and the slide rail 6 are covered, and the two ends of the guide plate 5 are set in an arc shape. The seat placement seat 3 is in the sitting state ( Figure 1 The cover 21 is provided with openings at the front and rear ends, and the openings are used for allowing the guide plate 5 to pass through in the left and right directions when the seat placement position seat 3 is rotated 90° to the left or right from the sitting state and the rotation locking structure 4 is in the unlocked state, so that the displacement limit of the seat placement position seat 3 in the left and right directions is released.

[0033] The rotary locking structure 4 with an unlocking function is widely used in existing child seats, so the rotary locking structure 4 can adopt the existing structure or the structure described in this embodiment. Specifically, the rotary locking structure 4 with an unlocking function includes a locking groove 9 located on the base 1 and a locking plug 10 installed on the seat placement position seat 3 and locked with the locking groove 9. There are four locking grooves 9, which are respectively located in the front middle, rear middle, left middle, and right middle of the upper end surface of the base 1, and the four locking grooves 9 are located on the same circumference with the rotation center of the seat placement position seat 3 as the center.

[0034] The locking plug 10 includes a housing 11, a vertical slide groove 12 is provided in the housing 11, a lock block 13 is slidably provided in the vertical slide groove 12 and is locked with the lock groove 9, a spring 14 is provided between the top of the lock block 13 and the housing 11, and the spring 14 is used to push the lock block 13 to protrude downward from the housing 11 and lock with the lock groove 9. A vertical guide groove 15 is provided on the side wall of the middle part of the housing 11, and an unlocking pin 16 is connected to the lock block 13 and is slidably matched with the vertical guide groove 15. The housing 11 is also provided with left and right slide grooves 17 arranged along the left and right directions, and an unlocking pull rod 18 is slidably provided in the left and right slide grooves 17, and two unlocking pull rods 18 are provided, and the two unlocking pull rods 18 are stacked front and back and arranged left and right, and an inclined hole 19 is provided on the unlocking pull rod 18 and is sleeved on the unlocking pin 16, and the inclined holes 19 of the two unlocking pull rods 18 are respectively arranged to be inclined outward and downward, and the inclined angles are the same.

[0035] Unlocking wrenches 20 corresponding to the unlocking rods 18 on the same side are respectively installed on both sides of the seat placement position seat 3. The unlocking rod 18 is rotatably installed on the seat placement position seat 3 through a torsion spring (not shown in the figure). The unlocking rod 18 is connected to the corresponding unlocking rod 18 through a pull wire 21. When the unlocking rod 18 rotates outward, the corresponding unlocking rod 18 is pulled outward by the pull wire 21, thereby driving the locking block 13 to disengage from the lock upward, and the torsion spring is used to automatically reset the unlocking wrench 20 inward.

[0036] The utility model also provides a child seat, comprising the above-mentioned child seat base, wherein a seat body (existing technology, not shown in the figure) is installed on the seat placement seat of the child seat base.
