Detailed Description

The technical contents of the preferred embodiments of the present invention will be more clearly and easily understood by referring to the drawings attached to the specification. The present invention may be embodied in many different forms of embodiments and the scope of the invention is not limited to the embodiments set forth herein.

In the drawings, structurally identical elements are represented by like reference numerals, and structurally or functionally similar elements are represented by like reference numerals throughout the several views. The size and thickness of each component shown in the drawings are arbitrarily illustrated, and the present invention is not limited to the size and thickness of each component. The thickness of the components may be exaggerated where appropriate in the figures to improve clarity.

As shown in fig. 1 to 3, the present invention provides a cradle, which comprises a base 1, a movable bed compartment 2, and a support 3, wherein the movable bed compartment 2 is movably connected to the support 3 disposed on the base 1 in a suspended manner, in this embodiment, a swing rod 4 is used to connect the movable bed compartment 2 to the support 3, so that the movable bed compartment 2 is reciprocated in a force direction when being subjected to a pushing force or a pulling force. Generally, there are four swing rods, two sets of which are respectively disposed at two ends of the movable bed 2, so as to stabilize the movable bed 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, and the winding drum 201 is positioned between the first fixed end 203 and the second fixed end 206, is rotatably fixed on the surface of the base 1 opposite to the movable bed 2, and has a rotating axis perpendicular to the base 1. The winding barrel 201 is wound with a first wire 202 and a second wire 205, the winding direction of the first wire 202 is opposite to that of the second wire 205, the free end of the first wire 202 is connected with the first fixed end 203, and the free end of the second wire 205 is connected with the second fixed end 206.

Therefore, when the winding barrel 201 rotates, the first line body 202 and the second line body 203 drive the movable bed box 2 to horizontally reciprocate according to the rotation degree of the winding barrel 201. In addition, the amplitude of the horizontal reciprocating motion can be adjusted according to the length of the wire body wound on the winding barrel 201, i.e. the number of turns of the winding wire.

As shown in fig. 4, the winding barrel 201 includes a first V-shaped opening 2011 and a second V-shaped opening 2012, the opening directions of the first V-shaped opening 2011 and the second V-shaped opening 2012 are the same as the rotation direction of the winding barrel 201, the first V-shaped opening 2011 and the second V-shaped opening 2012 both have circular holes 2013, one end of the first wire 202 and one end of the second wire 205 are fixed in the circular holes 2013, so that the first wire 202 and the second wire 205 can be tightly wound around the first V-shaped opening 2011 and the second V-shaped opening 2012 respectively.

Further, since the height difference exists when the movable bed carriage 2 performs the horizontal reciprocating motion, the V-shaped included angle between the first V-shaped opening 2011 and the second V-shaped opening 2012 is 30 ° to 120 ° to compensate the height difference, so as to prevent the wire from being separated during the rotation of the winding drum 201.

Further, the winding barrel 201 is driven by the motor 5, and the motor 5 is set to rotate in the forward and reverse directions to drive the winding barrel 201, so that the swing of the cradle is automated. The motor 5 can also be driven by a remote control device to realize remote control.

Further, the elastic member 204 is further included, the free end of the first wire 202 is connected to the first fixed end 203 through the elastic member 204, and the free end of the second wire 205 is connected to the second fixed end 206 through the elastic member 204. The elastic member 204 is a spring in this embodiment. Therefore, even if the motor 5 clamps an object in the swinging process of the movable bed compartment 2, the motor 5 cannot be locked, and can still pull the elastic part 207 to rotate, after the motor 5 rotates to the preset rotation limit, the elastic part can rotate reversely, so that the clamped object is separated, but the motor 5 does not reach the preset rotation limit all the time, and the motor is locked. By adjusting the number of winding turns of the first wire body 202 and the second wire body 205 on the winding barrel 201, the tightness of the elastic component 204 can be adjusted, damage is reduced when an object is impacted or clamped, and a buffering effect can be achieved.

Fig. 5 and 6 show schematic structural diagrams of another embodiment of the present invention, which is based on the foregoing embodiment, and two sides of the movable bed 2 are modified into bed flaps 207, and the bed flaps 207 can be turned down through hinges 208, so as to facilitate the movement of the infant by the user. In this embodiment, the hinge 208 is disposed inside the bed cover 207 and the bed 2, so that the hinge can be hidden in the inner space of the bed cover 207 corresponding to the bed 2 when the bed cover 207 is restored to the movable bed 2.

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

As shown in fig. 8, the bottom of the cradle of the present invention is further provided with a supporting connector 601, which is specifically disposed at the connecting corner of the bottom of the base 1 of the cradle to reinforce the base 1, and the supporting connector 601 may have any shape, which is not limited herein. In this embodiment, the base 1 is a hexahedron, and there are four supporting connectors 601 respectively connected to the connecting corners between the four sides of the bottom of the base 1, the rollers 6 are disposed corresponding to the supporting connectors 601 in number, and the rollers 6 are connected to the supporting connectors 601, so that the supporting points of the cradle can be moved to the supporting connectors 601.
