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: A baby crib with automatic swinging effect, such as Figures 1-4 As shown, it includes a bed body 1 and a rotating support base 2 installed at the lower end of the bed body 1. At least two guide grooves 4 are opened in the middle of the rotating support base 2. The guide groove 4 is located directly below the bed body 1. A first rotating cam 5 is slidably connected inside the guide groove 4, and the two first rotating cams 5 are located at different angles. A transmission rod 6 is simultaneously inserted into the middle of the two first rotating cams 5. A rotating motor 7 is installed at one end of the transmission rod 6, and the transmission rod 6 is installed at the output end of the rotating motor 7. A spring plate 14 is provided at the lower end of one side of the bed body 1, and a guide rod 15 is installed at the lower end of the spring plate 14. A reset spring 16 is provided below the guide rod 15. The reset spring 16 is used for rebound support of the spring plate 14.

[0026] First, start the rotating motor 7, so that the two first rotating cams 5 rotate simultaneously under the drive of the transmission rod 6, and based on the guide limit of the guide groove 4, ensure that the contact position of the first rotating cam 5 and the rotating support base 2 is accurate, so that the first rotating cam 5 squeezes the outer side of the rotating support base 2 to provide rotation support for the rotating support base 2, and when the bed body 1 rotates to the side of the spring plate 14 and presses the spring plate 14, the return spring 16 is pressed and contracted under the guidance of the guide rod 15. Based on the elastic support of the return spring 16 itself, and the first rotating cam 5 gradually leaves the contact range with the rotating support base 2 after rotating one end distance, at this time, the pressure on the spring plate 14 Reduce, under the rebound reset of the reset spring 16, drive the spring plate 14 to reset, thereby pushing the bed 1 to reset and rotate, and at the same time, under the continuous rotation of the other first rotating cam 5, it will gradually contact the bed 1 to prevent the bed 1 from resetting too much, and provide support for the bed 1 to continue to rotate, and then under the recontraction and expansion of the spring plate 14 again, drive the bed 1 to rotate again, so that under the combined use of the two first rotating cams 5 and the one side spring plate 14, the device can have the effect of automatic swinging, and by setting the contact time between the two first rotating cams 5 and the bed 1 to have a certain interval, it has the effect of automatic limiting, ensuring the controllable and safe rotation stroke.

[0027] like Figures 1-4 As shown, the protruding parts of the two first rotating cams 5 are symmetrically distributed, and the two first rotating cams 5 are in contact with the guide groove 4 respectively.

[0028] By setting the contact parts of the two first rotating cams 5 and the bed body 1 at different angles, they can respectively contact and support the bed body 1. Therefore, through the structural setting, the bed body 1 has a cyclical reciprocating swing effect, further improving its limiting support when the device swings.

[0029] like Figures 1-4 As shown, a rotating rod 3 is provided between the bed body 1 and the rotating support base 2. There are at least two rotating rods 3, and the two rotating rods 3 are located at opposite positions. The side of the rotating rod 3 away from the bed body 1 is rotatably connected to the side auxiliary plate 10.

[0030] An annular guide rail 11 is provided on the surface of the side auxiliary plate 10 close to the bed body 1 , and a guide block 9 is slidably connected to the inside of the annular guide rail 11 . The guide block 9 is installed on the outside of the bed body 1 .

[0031] With the support of the side auxiliary plates 10 on both sides, support and guiding effects are provided for the rotation of the bed body 1. For example, when the bed body 1 rotates, the rotating rod 3 arranged in the middle can provide support and limiting purposes for the rotation of the bed body 1 and the rotating support base 2. At the same time, under the guidance and limiting of the rotation trajectory of the guide block 9 by the annular guide rail 11, the effect of limiting the rotation stroke of the bed body 1 is further improved, and the safety and reliability of the swinging use of the device are improved.

[0032] Example 2: A baby crib with automatic swinging effect, such as Figures 1-4 As shown, a positioning groove 19 is provided on the lower half of one side of the bed body 1 , and a positioning plate 12 is inserted into the positioning groove 19 . The positioning plate 12 is installed between the two side auxiliary plates 10 .

[0033] Under the plug-in positioning of the positioning groove 19 and the positioning plate 12, the positioning groove 19 can be accurately positioned when swinging, ensuring the stability and safety of the central position of the device bed body 1 when rotating, thereby comprehensively protecting the bed body 1.

[0034] like Figures 1-4 As shown, a support plate 13 is provided between the two positioning plates 12 , a guide rod 15 is plugged into the support plate 13 and extends into the interior thereof, a support tube 17 is installed at the lower end of the support plate 13 , and a return spring 16 is installed inside the support tube 17 .

[0035] A fastening bolt 18 is installed at the lower end of the return spring 16 . The fastening bolt 18 is threadedly engaged with the support tube 17 and extends into the interior thereof. The guide rod 15 extends into the interior of the support tube 17 .

[0036] By rotating the fastening bolt 18, moving its distance inside the support tube 17, and adjusting the distance between the upper and lower ends of the reset spring 16, its elastic performance is increased, so that the spring plate 14 can perform stable reset support when facing pressure of different weights, thereby improving the diversity and durability of the device.

[0037] Working principle: First, start the rotating motor 7, so that the two first rotating cams 5 rotate simultaneously under the transmission of the transmission rod 6, providing rotation support for the rotating support base 2, and when the bed body 1 rotates to the side of the spring plate 14 and presses the spring plate 14, under the guidance of the guide rod 15, the return spring 16 is pressed and contracted, and the first rotating cam 5 gradually leaves the contact range with the rotating support base 2 after rotating a certain distance. At this time, the pressure on the spring plate 14 is reduced, and under the rebound and reset of the return spring 16, the spring plate 14 is driven to reset, thereby pushing the bed body 1 to reset and rotate. At the same time, under the continuous rotation of the other first rotating cam 5, it will gradually contact the bed body 1 to prevent the bed body 1 from resetting too much, and at the same time provide support for the bed body 1 to continue to rotate, and then under the recontraction and expansion of the spring plate 14, the bed body 1 is driven to rotate again, so that under the combined use of the two first rotating cams 5 and the spring plate 14 on one side, the device can have the effect of automatic swinging.

[0038] 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.
