One end of the pivot is fixedly connected to the other end of the swing arm, and the rotation anti-loosening component is installed on the other end of the pivot. The locking component is movably disposed between the pivot and the mounting base and is used to lock the pivot to the mounting base in the non-rotational state of the swing arm.
[0006] Optionally, the rotating shaft includes a turntable portion and a rod portion that are fixedly connected. The turntable portion is nested and fixed to the other end of the swing arm, and the rod portion is rotatably engaged with the mounting base and connected to the rotation anti-loosening component.

[0014] The beneficial effects of this utility model of a baby crib with a swing function are as follows: the bottom of the upright is connected to the base, the top of the upright is fixedly provided with a mounting seat, the other end of the swing arm is connected to the upright through a swing structure, and the crib is located at one end of the swing arm, thereby realizing the installation of the crib on the support structure, providing a basis for the overall deflection and swing of the crib and the swing arm relative to the upright. The swing structure includes a pivot, a locking component, and a rotation anti-loosening component. The pivot is rotatably mounted on the mounting seat and configured to be rotatable relative to the mounting seat, which ensures that the swing arm drives the crib located at the far end to deflect, such as under the action of external force. Furthermore, one end of the pivot is connected to the swing arm... The other end of the arm is fixedly connected, and the other end of the rotating shaft is equipped with the rotation anti-loosening component. This ensures that the rotating shaft is stably mounted on the mounting base and prevents it from detaching from the mounting base during rotation, thus ensuring the safety of the swing arm. Furthermore, the locking component is movably disposed between the rotating shaft and the mounting base. It does not affect the rotation of the rotating shaft when the swing arm is deflected, and is used to lock the rotating shaft to the mounting base when the swing arm is not deflected. This ensures that the swing arm is locked to the mounting base at the non-deflection angle, thereby limiting the overall deflection of the swing arm and the bed, ensuring their stable state at the non-deflection angle, and thus realizing the switching between the deflection state and the non-deflection state.

[0026] In the description of this specification, references to terms such as "embodiment," "one embodiment," and "one implementation" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or implementation is included in at least one embodiment or illustrative embodiment of the present invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or implementation. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or implementations.
[0027] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, this utility model embodiment proposes a baby crib with a swing function, including a base 1, a column 2, a swing arm 3, a bed body 4, and a swing structure. The bottom of the column 2 is connected to the base 1, and a mounting seat 5 is fixedly provided on the top of the column 2. The bed body 4 is located at one end of the swing arm 3. The swing structure includes a pivot 6, a locking member 7, and a rotational anti-loosening member 10. The pivot 6 is vertically arranged and rotatably mounted on the mounting seat 5 around its own axis. One end of the pivot 6 is fixedly connected to the other end of the swing arm 3, and the rotational anti-loosening member 10 is installed on the other end of the pivot 6. The locking member 7 is movably disposed between the pivot 6 and the mounting seat 5, and is used to lock the pivot 6 to the mounting seat 5 in the non-rotational state of the swing arm 3.
[0028] Specifically, the upright 2 can be vertically fixed to the surface of the base 1, and the swing arm 3 can be horizontally set. One end of the swing arm 3 is connected to the bed frame 4, and the other end of the swing arm 3 is connected to the upright 2 through a swing structure. Thus, the bed frame 4 and the swing arm 3 as a whole can swing relative to the upright 2. The bed frame 4 can be fixed to one end of the swing arm 3, or rotatably mounted on one end of the swing arm 3. That is, the bed frame 4 can realize the tilting function or the rotation function relative to the swing arm 3, which is not limited here. The main improvement of this utility model is the improvement of the swing function of the swing arm 3. The swing function is to realize the horizontal deflection of the swing arm 3 relative to the upright 2, thereby realizing the fixation of the bed frame 4 on one side (such as the left or right side) centered on the upright 2, realizing the use in a fixed scenario, or realizing the function of the bed frame 4 swinging back and forth to realize the baby soothing to sleep. The rotating shaft 6 is rotatably set on the mounting base 5 around its own axis. The rotating shaft 6 is vertically set, and one end of it is used to fix the swing arm 3. The swing arm 3 is rotatably set on the mounting base 5 through the rotating shaft 6, thereby realizing the relative tilting function or the rotation function of the swing arm 3 relative to the upright 2. The base 5 is deflectable, and a limiting device, such as a limiting stop, can be set on the rotation path to limit its continued rotation, thereby limiting the swing range. This allows the deflection range of the swing arm 3 and the rotating shaft 6 to be a fixed angular range, such as from -40° to 0°-40°. This 0° indicates the initial deflection state when the center line of the swing arm 3 is perpendicular to the column 2, or the non-deflection state. When in a non-deflection angle, such as at 0°, the rotating shaft 6 is locked to the mounting base 5 by the locking device 7, which limits the rotation of the swing arm 3 and ensures stability at the non-deflection angle. For example, at 0°, the rotating shaft 6 is inserted into the mounting base 5 by a threaded rod, thereby limiting the rotation of the swing arm 3. When swinging is required, the locking device can be released. The other end of the rotating shaft 6 is provided with a rotation anti-loosening device 10, which can be set inside the column 2 to prevent the rotating shaft 6 from disengaging from the mounting base 5 during rotation, thereby ensuring the stability of the rotation of the rotating shaft 6 and ensuring the safety of the swing arm 3.
[0029] In this embodiment, the bottom of the column 2 is connected to the base 1, and the top of the column 2 is fixedly provided with a mounting seat 5. The other end of the swing arm 3 is connected to the column 2 through a swing structure. The bed body 4 is located at one end of the swing arm 3, thereby realizing the installation of the bed body 4 on the support structure and providing a basis for the overall deflection and swing of the bed body 4 and the swing arm 3 relative to the column 2. The swing structure includes a pivot 6, a locking component 7, and a rotation anti-loosening component 10. The pivot 6 is rotatably disposed on the mounting seat 5 and configured to be rotatable relative to the mounting seat 5, which can ensure that the swing arm 3 drives the bed body 4 located at the far end to deflect as a whole, such as under the action of external force. Furthermore, one end of the pivot 6 is fixed to the other end of the swing arm 3. The other end of the pivot 6 is equipped with the rotation anti-loosening component 10, which ensures that the pivot 6 is stably mounted on the mounting base 5 and prevents the pivot 6 from detaching from the mounting base 5 during rotation, thereby ensuring the safety of the swing arm 3. Furthermore, the locking component 7 is movably disposed between the pivot 6 and the mounting base 5. It does not affect the rotation of the pivot 6 when the swing arm 3 is deflected, and is used to lock the pivot 6 to the mounting base 5 when the swing arm 3 is not deflected. This ensures that the swing arm 3 is locked to the mounting base 5 at the non-deflection angle, thereby limiting the overall deflection of the swing arm 3 and the bed 4, ensuring their stable state at the non-deflection angle, and thus realizing the switching between the deflection state and the non-deflection state.
[0030] like Figure 4 , Figure 5 and Figure 6 As shown, in an optional embodiment of the present invention, the rotating shaft 6 includes a turntable part 61 and a rod part 62 that are fixedly connected. The turntable part 61 is nested and fixed to the other end of the swing arm 3, and the rod part 62 is rotatably engaged with the mounting base 5 and connected to the rotation anti-loosening member 10.
[0031] Specifically, the rod 62 is fixed at the bottom center of the turntable 61. The rod 62 is rod-shaped and rotatably mounted on the mounting base 5. The rod 62 can be a threaded rod. Correspondingly, in order to ensure that the rotating shaft 6 does not detach from the mounting base 5, the anti-loosening component 10 can be a nut. The rod 62 can also be a general rod body. In this case, the anti-loosening component 10 can be a pin, which is inserted laterally into the bottom of the turntable 61 (a corresponding mounting hole can be provided) to prevent the rotating shaft 6 from detaching from the mounting base 5 during rotation. The above can ensure the stability of the rotating shaft 6 relative to the mounting base 5 in the deflection and swing.
[0032] like Figure 4 , Figure 5 and Figure 6As shown, in an optional embodiment of this utility model, the rod 62 extends vertically through the mounting base 5, the turntable 61 protrudes from the top of the mounting base 5, and the rod 62 partially protrudes from the bottom of the mounting base 5, with the exposed portion threadedly connected to the rotating anti-loosening member 10.
[0033] Specifically, the side of the mounting base 5 can be used to install a handle to push the crib. The rod 62 extends vertically through the mounting base 5 and can be installed relative to the thickness direction of the mounting base 5. Both the turntable 61 and the rod 62 protrude from the mounting base 5, ensuring that their top end, i.e., the turntable 61, is used to fix the swing arm 3, and its bottom end is used to install the rotation anti-loosening component 10. The bottom end of the rod 62 is used to thread the rotation anti-loosening component 10, which can be a nut, such as a self-locking nut. In this case, this part of the structure is located inside the column 2, and the inside of the column 2 is set as a hollow structure. The above can ensure that the mounting base 5 is clamped between the swing arm 3 and the rotation anti-loosening component 10, so as to realize the stable rotation of the rotating shaft 6 relative to the mounting base 5, thereby ensuring the stable deflection of the swing arm 3.
[0034] like Figure 2 , Figure 3 and Figure 5 As shown, in an optional embodiment of this utility model, a deflection limiting pin 15 is fixedly provided on the mounting base 5, and an arc-shaped rotating groove 611 is provided circumferentially on the turntable part 61, and the deflection limiting pin 15 slides in cooperation with the arc-shaped rotating groove 611.
[0035] Specifically, the arc-shaped groove 611 is set as an arc with the center of the rotating shaft 6. However, when adjusting the target deflection angle, the top of the deflection limiting pin 15 slides in the arc-shaped groove 611. The boundary of the arc-shaped groove 611 limits the continued rotation of the rotating shaft 6. The arc-shaped groove 611 is generally limited to a minor arc, that is, the deflection angle is limited to less than 180 degrees. Thus, based on the rotating shaft 6 being rotatably mounted on the mounting base 5, the rotating shaft 6 is limited to be deflectable relative to the mounting base 5, thereby realizing the overall deflection of the bed 4 and the swing arm 3.
[0036] like Figure 2 , Figure 3 and Figure 7 As shown, in an optional embodiment of the present invention, the locking member 7 includes an outer cylinder and an inner rod. The inner rod is configured to be slidably disposed inside the outer cylinder and elastically connected to the outer cylinder. The outer cylinder passes through the other end of the swing arm 3 and is installed on the turntable part 61. The mounting base 5 has an insertion hole. When the end of the inner rod protrudes from the outer cylinder, it is inserted into the insertion hole.
[0037] Specifically, the locking element 7 is a telescopic structure, and the inner insert rod can slide relative to the outer cylinder and is elastically connected to the outer cylinder, thereby achieving elastic extension and retraction. The outer cylinder passes through the swing arm 3, allowing the swing arm 3 to extend out, facilitating direct lifting operations from the outside. The outer cylinder is installed on the rod 62, for example, by a threaded pair or magnetically fixed to the rod 62, so the inner insert rod can slide relative to the outer cylinder. When the bottom of the inner insert rod is aligned with the insertion hole, the bottom of the inner insert rod enters the insertion hole under the action of elastic force, thereby restricting the rotation of the rotating shaft 6 on the mounting base 5. At this time, it is in a non-deflection state. When you want the swing arm 3 to be at the target deflection angle, pull the inner insert rod upward so that the bottom of the inner insert rod disengages from the insertion hole, and then swing the swing arm 3 towards the target deflection angle to rotate the bed 4 to one side of the relative center position. When you need to return the swing arm 3 to the non-deflection state of the center position, simply reverse the operation.
[0038] It should be noted that there is at least one socket, and at least one socket is located in the middle position. In other deflection states, due to the elastic force, the bottom of the inner plug will press against the surface of the mounting base 5, which can also ensure that the swing arm 3 is in a relatively stable state in the deflection state. When there are multiple sockets, they can be arranged along the periphery of the mounting base 5. Then, the bottom of the inner plug can enter the socket under multiple angle deflections, so that locking can be achieved under multiple angles.
[0039] like Figure 2 , Figure 3 and Figure 7 As shown, in an optional embodiment of this utility model, the outer cylinder includes a fixedly connected limiting part 72 and a mounting sleeve 73. The mounting sleeve 73 is threadedly engaged with the turntable part 61. The limiting part 72 is used to abut against the other end surface of the swing arm 3. The inner insert rod includes a fixedly connected operating part 71 and a plug-in part 74. The operating part 71 protrudes from the other end surface of the swing arm 3 and is connected to the mounting sleeve 73 through an elastic element. The plug-in part 74 is used to plug into the insertion hole.
[0040] Specifically, the operating part 71 is exposed on the surface of the swing arm 3, which facilitates the lifting operation. The mounting sleeve 73 is threadedly connected to the rod part 62, and the bottom end of the insertion part 74 can extend into the insertion hole. The outer cylinder can be screwed on by the limiting part 72 to achieve installation. An elastic element, such as a spring or elastic rope (not shown in the figure), is provided inside the mounting sleeve 73. The elastic rope is used to connect the mounting sleeve 73 and the operating part 71. Alternatively, the spring is sleeved on the periphery of the operating part 71, and the spring is installed as a whole inside the mounting sleeve 73, similar to the structure of a press-type ballpoint pen, to ensure that the inner insertion rod can elastically extend and retract inside the outer cylinder. The insertion hole is provided on the surface of the mounting base 5. Thus, in the non-deflected state, the insertion part 74 is inserted into the insertion hole, and the operating part 71 is pulled upward to unlock the 0° (middle position) positioning, so that the swing arm 3 can be deflected within a certain angle. If only the limiting part 72 is pulled without rotating, when the swing arm 3 returns to the 0° position, the insertion part 74 will automatically lock under the action of the rebound force, thereby limiting the rotation of the swing arm 3.
[0041] like Figure 2 , Figure 3 and Figure 4 As shown, in an optional embodiment of this utility model, the mounting base 5 has a vertical through mounting hole, and a bearing assembly is provided in the mounting hole. The rod 62 is rotatably connected to the mounting base 5 through the bearing assembly.
[0042] Specifically, the bearing assembly is mainly set to reduce rotational friction and resistance, so as to ensure that the rotation of the shaft 6 is more stable and smooth. For example, a ball bearing or other bearing can be set in the middle section of the mounting hole to assist the rotation of the shaft 6 on the mounting base 5, which is actually to assist the rotation of the rod 62 on the mounting hole.
[0043] like Figure 2 , Figure 3 and Figure 4 As shown, in an optional embodiment of this utility model, the bearing assembly includes a first bearing 13 and a second bearing 14. A first gasket 8 is provided between the turntable portion 61 and the mounting base 5. The second bearing 14 is pressed against the top end of the mounting hole by the first gasket 8, and the first bearing 13 is pressed against the bottom end of the mounting hole by the mounting gasket 9. Both the second bearing 14 and the first bearing 13 are sleeved on the periphery of the rod portion 62. The rotation anti-loosening member 10 is located on the side of the mounting gasket 9 away from the mounting base 5.
[0044] Specifically, by setting the first bearing 13 and the second bearing 14, that is, by providing bearing assemblies on both sides of the mounting hole, the rotation of the rod 62 in the mounting hole is made more lubricated and smooth. The first bearing 13 and the second bearing 14 are flat bearings (e.g., ultra-thin bearings). The first shim 8 is fixed to the top of the mounting base 5 to press the second bearing 14. Similarly, the mounting shim 9 is fixed to the bottom of the mounting base 5 to press the first bearing 13. Both the first shim 8 and the mounting shim 9 play the role of reducing the assembly gap. Both the first shim 8 and the mounting shim 9 can be fixed to the two end faces of the mounting base 5 by bolts. In this embodiment, the shims can all be damping sheets to ensure more stable deflection.
[0045] It should be noted that when the size of the first gasket 8 is sufficient, the first gasket 8 should have a through hole for the locking member 7 to pass through and a through hole for the deflection limit pin 15 to pass through.
[0046] like Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, in an optional embodiment of this utility model, from the mounting gasket 9 to the rotational anti-loosening component 10, a third bearing 12 and a second gasket 11 are sequentially provided between the mounting gasket 9 and the rotational anti-loosening component 10, with adjacent gaskets in contact with each other. The third bearing 12 is sleeved on the periphery of the rod portion 62. The rotational anti-loosening component 10 is generally a self-locking nut, which can be purchased directly from the market, to prevent the rotating shaft 6 from detaching from the mounting base 5.
[0047] Specifically, from the direction of the mounting shim 9 to the rotation anti-loosening component 10, that is, along the negative direction of the Z-axis in the figure, the mounting shim 9, the third bearing 12, the second shim 11 and the rotation anti-loosening component 10 are installed and placed close together in pairs. The second shim 11 will prevent the pivot 6 from loosening during the rotation of the swing arm 3. The third bearing 12 adopts a needle roller bearing to ensure the smooth rotation of the rotation anti-loosening component 10 and the second shim 11 relative to the mounting shim 9. The second shim 11 is also sleeved on the outer periphery of the rod 62. The setting of the second shim 11 facilitates assembly, reduces assembly gap, and ensures more stable deflection and swing.
[0048] As an optional embodiment of this utility model, in the non-deflection state of the swing arm 3, the center of the insertion hole, the midpoint of the arc-shaped groove 611, and the rotation axis of the rod 62 are located on the same straight line.
[0049] Specifically, when the swing arm 3 is in the middle position, it is in a non-deflected state, i.e., the 0° position. At this time, the center of the insertion hole, the midpoint of the arc-shaped rotating groove 611, and the rotation axis of the rod 62 are collinear. When in the deflected state, the locking member 7 disengages from the locking of the rotating shaft 6, and the rotating shaft 6 can deflect to both sides by an angle, such as... Figure 1 In the middle, it can deflect in the positive direction of the Y-axis, and of course it can also deflect in the opposite direction, such as deflecting in the negative direction of the Y-axis. For example, according to the size of the angle covered by the arc-shaped rotating groove 611 relative to the rotation axis, the rotation of the swing arm 3 is limited to ±40°. Combining the above embodiments, it can be seen that when it is in the non-deflection state, the locking member 7 can lock the rotating shaft 6 to the mounting base 5, that is, limit the swing of the rotating shaft 6.
[0050] In summary, the method of using this utility model is as follows: pull the locking member 7 upward to adjust the target deflection angle of the swing arm 3 left and right, put down the locking member 7, and complete the automatic locking when the locking member 7 is returned to the 0° center position.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.

[0052] Although the present invention has been disclosed above, its protection scope is not limited thereto.
