Description

Technical Field

[0001] The invention relates to the technical field of baby cribs, in particular to a baby crib with an adjustment function. Background Art

[0002] A crib is a common baby product that provides babies with a comfortable sleeping and resting environment. The mechanical structure of existing cribs on the market is generally a fixed structure, which can only ensure that babies can sleep, rest and other routine uses on the bed, but it is not convenient for parents to take care of their babies. For example, it is troublesome when parents need to change diapers or feed their babies. In order not to dirty the mattress when changing diapers, parents usually put a towel on the bed or need to buy a diaper changing table separately, which is extremely inconvenient. Even if a diaper changing table is used, it is necessary to lift the baby's legs or support the baby's back to complete the diaper changing operation.

[0003] Announcement No. CN209073920U discloses a baby bed with an adjustable function. After the locking assembly arranged along the head and foot of the bed is opened and the locking assembly arranged perpendicular to the head and foot of the bed is closed, the lifting assembly is raised and the second bed board is driven by the intermediate connecting member to rotate and lift an angle along the head and foot of the bed with the closed locking assembly as the axis, so that the baby's back can be raised in the baby bed, and the parents can feed the baby at this time, preventing the baby from choking when feeding while lying flat. At the same time, the parents do not need to carry the baby out of the bed for feeding, which reduces the parents' feeding time. The trouble and worry are solved by closing the locking assembly arranged along the direction of the head and foot of the bed and opening the locking assembly arranged perpendicular to the direction of the head and foot of the bed, and then the lifting assembly rises and drives the second bed board to rotate and lift an angle perpendicular to the direction of the head and foot of the bed with the closed locking assembly as the axis through the intermediate connecting member. At the same time, the placement table is pulled out, and the baby is placed on the placement table with the baby's back against the second bed board to complete the diaper changing operation, eliminating the process of parents taking the baby out of the crib and placing it on the diaper changing table when changing diapers, which is convenient for changing diapers. However, the patent still has the following problems in actual use: Although the baby bed with adjustment function can realize the baby's back to be lifted in the baby bed, parents can feed the baby at this time, and prevent the baby from choking when feeding while lying flat, the baby's sleeping position cannot be adjusted when the baby is sleeping, resulting in the baby staying in the same position for a long time, which is not conducive to the baby's development. The existing baby bed is convenient for moving and fixing the baby bed through universal wheels, but the contact area between the universal wheels and the ground is small, so the stability is poor, and it is easy to shake, which is not conducive to the stability of the baby feeding.

[0020] like Figure 8 and Fig. 9It can be seen that the lifting and adjusting mechanism 2 includes a top lifting bracket 201, which is symmetrically installed on the front and back sides of the bottom of the baby bed bottom plate 101. A motor cover 202 is fixedly installed on one side of the two top lifting brackets 201, and a lifting motor 203 is fixedly installed on one side of the motor cover 202. The output end of the lifting motor 203 is fixedly connected with a sprocket transmission assembly 204, and one side of the sprocket transmission assembly 204 is symmetrically threaded with a bidirectional threaded rod 205, and both sides of the two bidirectional threaded rods 205 are symmetrically threaded with lifting thread sleeves 206. The bottom of the lifting thread sleeve 206 is rotatably connected with a lifting rotating rod 207, and a lifting rotating shaft 208 is rotatably connected between the two lifting rotating rods 207.

The lifting motor 203 is used to drive the sprocket transmission assembly 204 and the two-way threaded rod 205 to rotate, so that the two lifting threaded sleeves 206 move relatively on the outside of the two-way threaded rod 205. At the same time, under the action of the lifting rotating shaft 208, the lifting rotating rod 207 is rotated, so that the bottom lifting bracket 211 and the top lifting bracket 201 move relatively, so that the height of the baby bed can be adjusted to make the baby bed flush with the parents' bed, which is convenient for feeding the baby.

[0021] like Fig.10 and 11As shown, an opening and closing bracket 214 is fixedly installed inside the stabilizing bracket 213, an opening and closing sliding rod 215 is fixedly installed around the inside of the opening and closing bracket 214, an opening and closing sliding sleeve 216 is slidably connected to the outside of the opening and closing sliding rod 215, an opening and closing spring 217 is fixedly installed on one side of the opening and closing sliding sleeve 216, an opening and closing rotating rod 218 is rotatably connected to the bottom of the opening and closing sliding sleeve 216, a supporting bottom plate 219 is fixedly installed at the bottom center of the supporting bottom plate 219, and a supporting sleeve 220 is fixedly installed at the bottom center of the supporting bottom plate 219. The outer side of the support sleeve 220 is slidably connected with a support spring 221, and a support anti-slip pad 222 is fixedly installed at the bottom of the support spring 221. A connecting sliding rod 223 is fixedly installed on the top of the opening and closing sliding sleeve 216, and a fixed block 224 is fixedly installed on one side of the top of the connecting sliding rod 223.

The fixing ring 227 and the fixing rotating plate 226 are fixedly installed with unlocking paddles 229. By stepping on the fixing rotating plate 226, the fixing sliding rod 225 and the supporting bottom plate 219 are driven down. Under the action of the opening and closing rotating rod 218, the opening and closing sliding sleeve 216 squeezes the opening and closing spring 217 and drives the connecting sliding rod 223 and the fixing block 224 to move relatively. The characteristics of the combined connection can achieve the fixation of the support base plate 219. Through the elastic force of the support spring 221, the support anti-skid pad 222 can stably support the ground, thereby improving the support stability of the entire crib. When the crib needs to be moved, the unlocking paddle 229 is kicked to drive the fixed rotating plate 226 and the fixed clamping ring 227 to rotate, so that the fixed clamping block 224 is moved out through the unlocking slide groove 228, which can realize the upward movement of the support base plate 219 and separate the support anti-skid pad 222 from the ground, thereby facilitating the movement of the crib.

[0022] Working principle: Before using this baby bed with adjustable function, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Fig.11As shown, first, the lifting motor 203 is used to drive the sprocket transmission assembly 204 and the two-way threaded rod 205 to rotate, so that the two lifting threaded sleeves 206 move relatively on the outside of the two-way threaded rod 205. At the same time, under the action of the lifting rotating shaft 208, the lifting rotating rod 207 is rotated, so that the bottom lifting bracket 211 and the top lifting bracket 201 move relatively, so that the height of the baby bed can be adjusted to make the baby bed flush with the parents' bed, which is convenient for baby feeding. The fixed sliding rod 225 and the supporting bottom plate 219 are driven down by stepping on the fixed rotating plate 226, and under the action of the opening and closing rotating rod 218, the opening and closing sliding sleeve 216 squeezes the opening and closing spring 217 and opens. The connecting sliding rod 223 and the fixed clamping block 224 are driven to move relative to each other. The fixing block 224 is connected with the fixing clamping ring 227 by the engagement, so that the support base plate 219 can be fixed. The elastic force of the support spring 221 can make the support anti-skid pad 222 stably support the ground, thereby improving the support stability of the entire crib. When the crib needs to be moved, the unlocking paddle 229 is kicked to drive the fixed rotating plate 226 and the fixing clamping ring 227 to rotate, so that the fixed clamping block 224 is moved out through the unlocking slide groove 228, which can realize the upward movement of the support base plate 219 and separate the support anti-skid pad 222 from the ground, thereby facilitating the movement of the crib.

[0023] Secondly, the rotating motor 104 is used to drive the rotating worm 105 to rotate, and the meshing connection between the rotating worm 105 and the rotating worm wheel 106 is used to realize the rotation of the adjusting rotating disk 107, and the sliding connection between the first mounting threaded block 112 inside the adjusting rotating disk 107 and the reciprocating slide groove 115 inside the reciprocating bracket 114 is used to realize the swing of the reciprocating bracket 114. The reciprocating bracket 114 drives the rotating connecting shaft 113 and the swinging bed 118 to swing while swinging, so that the baby inside the swinging bed 118 can be swung and shaken, which is convenient for coaxing the baby to sleep. By rotating the adjusting knob 109 to drive the adjusting threaded rod 110 to rotate, the adjusting threaded sleeve 111 drives the first mounting threaded block 112 to move, and the rotation radius of the first mounting threaded block 112 can be adjusted, thereby adjusting the swing amplitude of the swinging bed 118, thereby improving the effect of coaxing the baby to sleep.

[0024] Finally, the reciprocating bracket 114 can be rotated and fixed by rotating several fixed threaded sleeves 116 and second mounting threaded blocks 117 on both sides of the worm gear 106, thereby changing the rotation angle of the swing bed 118, which is convenient for adjusting the sleeping position of the baby, so that the baby can sleep lying down or sleeping on the side, which is beneficial to the development of the baby's head shape. The baby can be safely protected by the safety strap 119 to avoid the phenomenon of rolling over when the baby sleeps on the side, which is not conducive to the baby's sleeping safety. The airbag pillow 120 can be inflated by the air pump 121, and the height of the airbag pillow 120 can be adjusted according to the age of the baby, which is beneficial to the development of the baby's head. The protective pillow 123 can provide secondary protection for the baby when the baby sleeps on the side, further improving the safety of the baby sleeping on the side. The baby can be protected by the guardrail 124.
