DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] Example 1: An anti-dumping mechanism for a baby crib, such as Figure 1 - Figure 4As shown, it includes a bed board 1, at least four bed board support columns 2 are installed on the lower surface of the bed board 1, and the four bed board support columns 2 are symmetrically distributed, a telescopic storage block 3 is installed on the lower end of the bed board support column 2, and the telescopic storage block 3 is slidably connected to the inside of the telescopic storage block 3. A support column 6 is installed on the upper end of the telescopic block 4, and the support column 6 extends out of the lower surface of the telescopic block 4. The support column 6 is threadedly connected to a rotating bolt 5, and one end of the rotating bolt 5 is rotatably connected to a support plate 7. The outer surface of the telescopic storage block 3 is threadedly connected to a limiting bolt 25, which extends to the inside of the telescopic storage block 3, and the limiting bolt 25 limits the telescopic block 4. A universal wheel 16 is installed on the lower surface of the telescopic storage block 3.

[0026] With the rolling support of the universal wheels 16, the crib is pushed to a suitable position. At this time, according to the size of the range on both sides of the crib, the telescopic blocks 4 are stretched to the appropriate positions respectively, and then the limit bolts 25 are twisted clockwise so that the limit bolts 25 can tighten and limit the telescopic blocks 4 to ensure that the telescopic blocks 4 do not move horizontally. Then, the rotating bolts 5 are adjusted to drive the support plate 7 toward the ground. When the support plate 7 is close to the ground, the rotating bolts 5 can be fine-tuned to make the universal wheels 16 slightly off the ground to ensure the stability of the crib. At the same time, if the ground height is different, the rotating bolts 5 can be adjusted separately to make the support plate 7 close to the ground, thereby improving the applicability of the crib.

[0027] like Figure 1 - Figure 4 As shown, a rotation groove 17 is provided on the upper surface of the telescopic block 4, and a support telescopic rod 8 is rotatably connected inside the rotation groove 17. The end of the support telescopic rod 8 away from the rotation groove 17 is fixedly connected to the support block 9, and at least two support rod fixing columns 10 are installed on the upper surface of the support block 9. The inner surfaces of the two support rod fixing columns 10 are fixedly connected to the support rod rotating columns 11, and the outer surface of the support rod rotating columns 11 is rotatably connected to the support rod fixing block 12, and the support rod fixing block 12 is fixedly connected to the bed board 1.

[0028] A plurality of bolt holes 19 are formed on the outer surface of the supporting telescopic rod 8 , and the plurality of bolt holes 19 pass through the interior of the supporting telescopic rod 8 , and the bolt holes 19 are threadedly engaged with fixing bolts 18 .

[0029] When the telescopic block 4 moves horizontally, it will drive the supporting telescopic rod 8 to stretch at the same time. Under the support and limit of the rotating groove 17 and the supporting rod rotating column 11, the stability of the operating angle of the supporting telescopic rod 8 is guaranteed. When the telescopic block 4 reaches the appropriate position, the fixing bolt 18 on the supporting telescopic rod 8 is twisted clockwise so that the fixing bolt 18 is tightly connected with the bolt hole 19, which plays a limiting role on the supporting telescopic rod 8 and ensures the stability of the operation of the supporting telescopic rod 8. The supporting telescopic rod 8, the telescopic block 4 and the bed board support column 2 cooperate with each other to form a triangle. Because the triangle has stability, the stability of the baby bed is guaranteed.

[0030] Example 2: An anti-dumping mechanism for a baby crib, such as Figure 1 - Figure 4 As shown, at least four protective support blocks 14 are installed on the upper surface of the bed board 1, and the four protective support blocks 14 are symmetrically distributed. A plurality of snap grooves 20 are opened on the inner surface of the protective support blocks 14.

[0031] Several protective telescopic rods 13 are installed on the upper surface of the bed board 1, and the protective telescopic rods 13 extend out of the lower surface of the bed board 1. The upper ends of the protective telescopic rods 13 are fixedly connected to protective support rods 15, and the protective support rods 15 are inserted into the protective support blocks 14.

[0032] Sliding grooves 24 are provided at both ends of the protection support rod 15 . A buckle 21 is slidably connected inside the sliding groove 24 . A spring 23 is fixedly connected to one side of the buckle 21 , and one end of the spring 23 is fixedly connected to the protection support rod 15 .

[0033] A buckle moving handle 22 is installed on the upper surface of the buckle 21 , and the buckle moving handle 22 slides inside the sliding groove 24 .

[0034] After the baby is placed in the crib, the buckle moving handle 22 is pulled inward, driving the buckle 21 to move toward the side of the spring 23, so that the buckle 21 is disengaged from the buckle groove 20. At this time, the protective support rod 15 and the protective telescopic rod 13 can be moved up and down at the same time, and then the protective support rod 15 is moved to a place where the baby cannot grab it, and the buckle moving handle 22 is released. Under the rebound action of the spring 23, the buckle 21 will automatically return to the inside of the buckle groove 20. At this time, the spring 23 is in a normal state, which plays a limiting support role for the protective support rod 15 and the protective telescopic rod 13 to ensure the stability of operation. At the same time, the four sides of the crib can be adjusted separately, which is convenient for caring for the baby and improves the applicability of the crib.

[0035] Working principle: With the rolling support of the universal wheel 16, push the crib to the appropriate position. At this time, according to the size of the range on both sides of the crib, stretch the telescopic block 4 to the appropriate position respectively, and then twist the limit bolt 25 clockwise to make the limit bolt 25 tighten and limit the telescopic block 4. Then adjust the rotating bolt 5 to drive the support plate 7 toward the ground so that the support plate 7 is close to the ground. When the telescopic block 4 moves horizontally, it will drive the supporting telescopic rod 8 to stretch at the same time. When the telescopic block 4 reaches the appropriate position, twist the fixing bolt 18 on the supporting telescopic rod 8 clockwise to fix it. The fixed bolt 18 is tightly connected to the bolt hole 19, which plays a limiting role in supporting the telescopic rod 8. Then, after putting the baby into the crib, the buckle moving handle 22 is pulled inward to drive the buckle 21 to move toward the side of the spring 23, so that the buckle 21 is disengaged from the buckle groove 20. At this time, the protective support rod 15 and the protective telescopic rod 13 can be moved up and down at the same time, and then the protective support rod 15 is moved to a place where the baby cannot grab it, and the buckle moving handle 22 is released. Under the rebound action of the spring 23, the buckle 21 will automatically return to the inside of the buckle groove 20. At this time, the spring 23 is in a normal state.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
