Detailed ways

Hereinafter, a number of preferred embodiments of the present invention will be introduced with reference to the accompanying drawings in the specification to make the technical content clearer and easier to understand. The present invention can be embodied by many different forms of embodiments, and the protection scope of the present invention is not limited to the embodiments mentioned in the text.

In the drawings, components with the same structure are denoted by the same numerals, and components with similar structures or functions are denoted by similar numerals. The size and thickness of each component shown in the drawings are arbitrarily shown, and the present invention does not limit the size and thickness of each component. In order to make the illustration clearer, the thickness of the components is appropriately exaggerated in some places in the drawings.

As shown in Figures 1 to 3, the present invention provides a baby cradle, which includes a base 1, a movable bed box 2, and a bracket 3. The movable bed box 2 is movably connected to the bracket 3 provided on the base 1. In the embodiment, the swing rod 4 is used to connect the movable bed box 2 and the bracket 3, so that the movable bed box 2 reciprocates in the direction of the force when it is pushed or pulled. Generally, there may be four swing rods, two groups in total, which are respectively arranged at both ends of the movable bed box 2 to stabilize the movable bed box 2.

The bottom surface of the movable bed 2 is provided with a first fixed end 203 and a second fixed end 206 along the moving direction of the movable bed 2. The winding barrel 201 is located between the first fixed end 203 and the second fixed end 206, and is It is rotatably fixed on the opposite surface of the base 1 and the movable bed compartment 2, and its rotation axis is perpendicular to the base 1. A first wire body 202 and a second wire body 205 are wound on the winding barrel 201. The winding direction of the first wire body 202 is opposite to the second wire body 205. The free end of the first wire body 202 is connected to the first fixed end 203. The free end of the two-wire body 205 is connected to the second fixed end 206.

Therefore, when the bobbin 201 rotates, the first bobbin 202 and the second bobbin 203 will drive the movable bed 2 to perform horizontal reciprocating motion according to the degree of rotation of the bobbin 201. In addition, the swing amplitude of the horizontal reciprocating motion can be adjusted according to the length of the wire body wound on the bobbin 201, that is, the number of winding turns.

As shown in FIG. 4, the bobbin 201 includes a first V-shaped opening 2011 and a second V-shaped opening 2012, and the opening directions of the first V-shaped opening 2011 and the second V-shaped opening 2012 are consistent with the rotation direction of the bobbin 201 , The first V-shaped opening 2011 and the second V-shaped opening 2012 both have a circular hole 2013, and one end of the first wire body 202 and the second wire body 205 are fixed in the circular hole 2013, so that the first wire body 202 and the second wire body 205 It can be wound tightly around the first V-shaped opening 2011 and the second V-shaped opening 2012, respectively.

Furthermore, since the movable bed 2 has a height difference when performing horizontal reciprocating motion, the V-shaped included angle between the first V-shaped opening 2011 and the second V-shaped opening 2012 is set to be 30° to 120° to compensate for the height difference. The wire body is prevented from detaching during the rotation of the bobbin 201.

Further, the reeling bucket 201 is driven by a motor 5, and the motor 5 is set to rotate forward and backward to drive the reeling bucket 201 to automate the swing of the baby cradle. The motor 5 can also be driven by a remote control device to realize remote remote control.

Furthermore, it further includes an elastic component 204, the free end of the first wire body 202 is connected to the first fixed end 203 through the elastic component 204, and the free end of the second wire body 205 is connected to the second fixed end 206 through the elastic component 204. In this embodiment, the elastic member 204 is a spring. Therefore, even if the motor 5 clamps an object during the swing of the movable bed compartment 2, the motor 5 will not be stuck, and the elastic member 207 can still be pulled to rotate. After the motor 5 rotates to the preset rotation limit, and It can be rotated in the reverse direction, so that the clamped object is separated, instead of the motor 5 has not reached the preset rotation limit, causing the motor to be stuck. By adjusting the number of winding turns of the first thread body 202 and the second thread body 205 on the winding barrel 201, the tightness of the elastic member 204 can also be adjusted to reduce damage when hitting or pinching an object, and can also serve as a buffer.

Figures 5 and 6 show a schematic structural view of another embodiment of the present invention. On the basis of the foregoing embodiment, the two sides of the movable bed compartment 2 are modified into bed compartment flaps 207, and the bed compartment flaps 207 can be turned down by hinges 208 , It is convenient for the user to move the baby. In this embodiment, the hinge 208 is arranged inside the bed compartment flip 207 and the bed compartment 2, so when the bed compartment flip 207 is reset to the movable bed compartment 2, the hinge can be hidden in the corresponding bed compartment flip 207 and the bed compartment 2. In the internal space.

Further, the bed compartment flip 207 is provided with a latch 209, the latch 209 includes a pin top 2091, a first rod portion 2092 and a second rod portion 2093, the plug 209 passes through the bed compartment flip 207 in a direction parallel to the bed compartment flip 207 A part of the second rod 2093 is exposed. A pin groove 211 is provided on the movable bed 2 at a position corresponding to the second rod 2093, and the second rod 2093 is inserted into the pin groove 211 so that the bed cover 207 is fixed on the movable bed 2. The diameter of the first rod portion 2092 is narrower than the pin top 2091 and the second rod portion 2093. A spring 210 is sleeved on the first rod portion 2092. The spring 210 can only move in the through hole formed by the bolt 209 passing through the bed cover 207. When the pin top 2091 is pulled, the spring 210 is compressed, and the second rod portion 2093 leaves the pin groove 211, so that the bed compartment flip 207 is turned down through the hinge 208. When the pin top 2091 is released, the latch 209 is reset by the spring 210.

As shown in Fig. 8, the bottom of the baby cradle of the present invention is also provided with a supporting connecting member 601, which is specifically arranged at the connecting corner of the bottom of the base 1 of the baby cradle. The base 1 is reinforced, and the supporting connecting member 601 can be It is any shape and is not limited here. In this embodiment, the base 1 is a hexahedron, and there are four support connectors 601 respectively connected to the connecting corners between the four sides of the bottom of the base 1. The number of rollers 6 and the number of support connectors 601 are set correspondingly, and the rollers 6 are connected to In this way, the support point of the baby cradle can be moved to the support connector 601. Compared with the technical solution in the prior art that the rollers are arranged on the side of the bracket, the load-bearing capacity of the baby cradle is increased. The structure is safer.

The preferred embodiments of the present invention have been described in detail above. It should be understood that many modifications and changes can be made according to the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should fall within the protection scope determined by the claims.
