[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] like Figure 1-5 As shown, an adjustable children's high chair for childcare centers includes a child seat 1, a support frame 2, a limiting member 3, a connector 4, and a plug-in member 5. The bottom of the child seat 1 is provided with several support frames 2, which are metal support frames used to support the child seat 1. The height of the child seat 1 relative to the ground can be adjusted by adjusting the spacing between the support frames 2. The support frames 2 are arranged in a circular array around the center point of the bottom of the child seat 1 to support it. The design of multiple support frames 2 increases the stability of the child seat 1 when supported. A limiting member 3 is fitted onto the support frame 2 to limit the degree of closure of the support frame 2. In actual use, multi-directional adjustable support feet are provided at the bottom of the support frame 2. The shape of the support feet is not unique and should be selected according to the requirements of the support frame 2 in this application. The bottom of the adjustable support feet will always be in contact with the ground to limit the support frame 2 and prevent the support frame 2 from self-closing during use.

[0028] The limiting component 3 includes a connecting collar 31 sleeved on the support frame 2. The connecting collar 31 has a hollow through groove inside, which is used to limit the closing angle of the support frame 2 and reduce the probability of the support frame 2 spreading out after stacking. The connecting collar 31 has several slots 32, which penetrate through the side wall of the connecting collar 31 and are used for the placement and rotation of the plug-in 5. A rotating rod 33 is inserted into each slot 32. The rotating rod 33 has a circular design and is used to support the rotation of the plug-in 5. The plug-in 5 is sleeved on each rotating rod 33, driving the plug-in 5 to rotate around the center of the rotating rod 33 to abut against the support frame 2 for limiting. When in use, the plug-in 5 will abut against the support frame 2.

[0029] The bottom of the child seat 1 is detachably connected to a connector 4, which is used to connect the child seat 1 and the support frame 2. The connector 4 includes a connecting sleeve plate 41 that is bolted to the bottom of the child seat 1. The connecting sleeve plate 41 is made of iron.

[0030] To achieve the connection between the connecting collar 31 and the connector 4, a plug-in ring 43 is provided on the outer periphery of the bottom of the connecting sleeve plate 41. The connecting sleeve plate 41, the plug-in ring 43, and the connecting collar 31 are all circular. The diameter of the plug-in ring 43 is smaller than the inner diameter of the connecting collar 31. The plug-in ring 43 and the connecting collar 31 are connected together. A limiting plate 21 for limiting the limiting member 3 is connected to the outer surface of the support frame 2. The limiting plate 21 will limit the limiting member 3. When the support frame 2 is closed to the minimum position, the total diameter of the limiting plate 21 and the support frame 2 will be larger than the inner diameter of the connecting collar 31, so as to prevent the connecting collar 31 and the support frame 2 from falling off.

[0031] The bottom of the connecting sleeve plate 41 is provided with four vertical slots 42 that are inserted into the support frame 2. The bottom of the vertical slot 42 extends through the insertion ring 43 to the outside of the connecting sleeve plate 41. Both sides of the vertical slot 42 extend through the connecting sleeve plate 41 and the insertion ring 43, so that the support frame 2 can rotate at an angle within the vertical slot 42.

[0032] Multiple adsorption blocks 34 are fixed to the top of the connecting collar 31 by the existing connection method. The top of the adsorption block 34 is adsorbed to the bottom of the connecting sleeve plate 41. The adsorption block 34 is made of magnet. When the support frame 2 is opened for use, the top of the connecting collar 31 will be adsorbed and limited to the bottom of the connecting sleeve plate 41. This reduces the probability of the support frame 2 closing due to the connecting collar 31 and the insertion ring 43 falling off during use, thus reducing the probability of dangerous events.

[0033] The overall effect of this embodiment is that when the support frame 2 is unfolded, the top of the connecting collar 31 will adhere to and limit the bottom of the connecting plate 41, reducing the possibility of the connecting collar 31 and the plug ring 43 detaching during use, causing the support frame 2 to close and reducing the probability of dangerous incidents. At this time, adjusting the angle between the four support frames 2 and the connecting plate 41 allows for height adjustment and support of the child seat 1 and the ground, and the adjustable support feet are in contact with the ground. When the support frame 2 is folded, the adsorption block 34 and the connecting plate 41 are separated, and the connecting collar 31 slides down until the bottom of the connecting collar 31 abuts against the top of the limiting plate 21, closing and limiting the support frame 2. At the same time, the plug 5 will limit it, reducing the possibility of the limiting member 3 sliding during use.

[0034] Example 2

[0035] like Figure 1-5 As shown, an adjustable high chair for a childcare center includes a connector 5 comprising a rotating cylinder 52 sleeved on the surface of a rotating rod 33. The rotating cylinder 52 is rotatable on the rotating rod 33. A rubber block 51 is welded to one side of the rotating cylinder 52. The rubber block 51 is made of rubber and, as shown... Figure 5The triangular design shown has a side wall away from the rotating cylinder 52 that is longer than the side wall near the rotating cylinder 52 to increase the contact surface between the rubber block 51 and the support frame 2. The side wall of the rubber block 51 away from the rotating cylinder 52 is rough to abut against the support frame 2 and prevent slippage when the connecting collar 31 and the support frame 2 are inserted. A push block 53 is welded to the rotating cylinder 52 on the opposite side of the rubber block 51 to adjust the positional relationship between the rubber block 51 and the support frame 2. No limit is required between the insertion part 5 and the rotating rod 33. When the limit part 3 and the support frame 2 are sleeved and closed, the lower limit of the rubber block 51 is sufficient to limit the position of the connecting collar 31 and the support frame 2.

[0036] A rotating shaft for rotating connection of support frame 2 is provided in vertical groove 42. The rotating shaft and support frame 2 are connected by friction limiting connection to reduce the phenomenon of self-rotation of support frame 2 after rotation.

[0037] The effect achieved by the entire second embodiment is that when the bottom of the connecting collar 31 and the top of the limiting plate 21 abut, it moves to the push block 53 until the rubber block 51 and the support frame 2 abut. The abutting rubber block 51 and the support frame 2 will prevent the connecting collar 31 and the support frame 2 from sliding when they are inserted. When the rubber block 51 and the support frame 2 abut, the position of the rubber block 51 will also be limited.

[0038] Working principle: When using the adjustable high chair for children in this childcare center, first check whether each part is intact. When the support frame 2 is open, the top of the connecting collar 31 will adhere to the bottom of the connecting plate 41 to limit the movement, reducing the possibility of the connecting collar 31 and the plug ring 43 falling off during use, which would cause the support frame 2 to close and reduce the probability of dangerous events. At this point, adjust the angle between the four support frames 2 and the connecting sleeve plate 41 to achieve height adjustment and support between the child seat 1 and the ground, and make the adjustable support feet fit against the ground. When the support frame 2 is folded, the suction block 34 and the connecting sleeve plate 41 are separated, and the connecting collar 31 is slid down until the bottom of the connecting collar 31 and the top of the limiting plate 21 abut. When the bottom of the connecting collar 31 and the top of the limiting plate 21 abut, turn to the push block 53 until the rubber block 51 and the support frame 2 abut. The abutting rubber block 51 and the support frame 2 will prevent the connecting collar 31 and the support frame 2 from sliding when they are inserted. When the rubber block 51 and the support frame 2 abut, the position of the rubber block 51 will also be limited, and the support frame 2 will be closed and limited, reducing the phenomenon of sliding of the limiting part 3 during use. Finally, the work of the adjustable child high chair for the childcare center is completed.
