[0037] The present invention will now be described in detail with reference to the accompanying drawings.

[0038] like Figures 1 to 4 As shown, this utility model discloses a double-locking baby rocker, including a rotating support 1 and a rocker base 2. The rotating support 1 is provided with a connector 11, and the rocker base 2 is provided with a connecting groove 21. The connecting groove 21 is slidably engaged with the connector 11.

[0039] The rocking chair base 2 is provided with a first locking assembly 3 and a second locking assembly 4.

[0040] The first locking assembly 3 extends radially into the connecting groove 21 and connects to the connecting member 11;

[0041] The second locking assembly 4 passes through the connecting groove 21 along the axial direction of the connector 11 and is connected to the connector 11.

[0042] The connector 11 and the connecting groove 21 are locked from different dimensions by a radial first locking assembly 3 and an axial second locking assembly 4. Working together, they secure the connector 11 and the connecting groove 21 in all directions, ensuring a stable connection. This double locking enhances the stability of the connection between the rotating support 1 and the rocker base 2, preventing accidental separation during use and ensuring the safety of the infant.

[0043] In use, the connecting groove 21 is slidably fitted into the connector 11, and the first locking assembly 3 extends radially into the connecting groove 21 to connect with the connector 11, and the second locking assembly 4 passes through the connecting groove 21 axially to connect with the connector 11, thereby achieving double locking of the rotating support 1 and the rocking chair base 2, ensuring stable connection and preventing accidental separation.

[0044] like Figure 4 As shown, the connector 11 in this embodiment is provided with a slot 111 in the radial direction; the slot 111 provides a locking engagement part for the first locking assembly 3 in the radial direction; so that the connector 11 and the first locking assembly 3 can cooperate to achieve radial locking.

[0045] The first locking assembly 3 includes a slide key 31, a latch 32, and a return spring 33; wherein, the latch 32 can be right-angled or straight, and this embodiment uses a right-angled latch 32 as an example.

[0046] The rocking chair base 2 has a cavity 22 inside. The buckle 32 has a rotation point 321 that is rotatably connected to the cavity 22. The end of the buckle 32 away from the rotation point 321 is locked with a locking hook 322 in the slot 111. The buckle 32 is rotated by the rotation point 321, so that the locking hook 322 can be locked or separated from the slot 111. This achieves the locking and unlocking of the first buckle assembly 3 in the radial direction.

[0047] The reset spring 33 is located on the other side of the buckle 32 away from the rotation point 321, and the reset spring 33 abuts against the inner wall of the cavity 22; the reset spring 33 provides reset power to the buckle 32 through its own elasticity; so that the locking hook 322 of the buckle 32 remains locked with the slot 111 when there is no external force, thereby enhancing the locking stability.

[0048] The slide key 31 is slidably connected to the cavity 22 and abuts against the side of the latch 32 opposite to the return spring 33. Part of the slide key 31 is exposed outside the cavity 22. The latch 32 is rotated by sliding operation, which facilitates the locking and unlocking of the latch 32 from the outside.

[0049] The entire assembly, through the cooperation of slide key 31, buckle 32 and return spring 33, achieves a stable radial locking between the rotating support 1 and the rocking chair base 2.

[0050] like Figure 3 As shown, in this embodiment, the connecting groove 21 is provided with a limiting hole 211 through the axial direction of the connector 11, and the connector 11 is provided with a locking groove 112 in the axial direction.

[0051] The second latch assembly 4 includes a limiting plate 41, a limiting post 42, and a return spring 43;

[0052] The limiting plate 41 is disposed outside the limiting hole 211, and the limiting plate 41 is provided with a sliding hole 411 through which the axial direction is provided;

[0053] The limiting post 42 is slidably disposed in the sliding hole 411 and the limiting hole 211 and extends into the locking groove 112;

[0054] The reset spring 43 is disposed between the limiting plate 41 and the outer side of the connecting groove 21, and is used to keep the limiting post 42 extending into the locking groove 112.

[0055] Specifically, the limiting hole 211 provides an axial sliding channel for the limiting post 42 of the second locking assembly 4, so that the limiting post 42 can extend into the connector 11 for axial locking.

[0056] The locking groove 112 serves as the engaging part of the limiting post 42; the locking groove 112 cooperates with the limiting post 42 to achieve axial locking.

[0057] The limiting plate 41 is fixed to the surface of the connecting groove 21 by adhesive or bolts and is located outside the limiting hole 211. The sliding hole 411 provides a sliding support structure for the limiting post 42, ensuring that the limiting post 42 slides stably.

[0058] The limiting post 42 engages or disengages with the locking groove 112 by sliding; thus locking and unlocking the connecting groove 21 and the connecting member 11 in the axial direction.

[0059] The return spring 43 uses its own elasticity to provide reset and holding force, so that the limit post 42 remains locked when there is no external force, thus enhancing the axial locking stability.

[0060] The entire assembly, through the cooperation of the limiting hole 211 of the connector 11, the sliding hole 411 of the limiting plate 41, the limiting post 42, and the return spring 43, achieves a stable axial lock between the rotating support 1 and the rocking chair base 2.

[0061] like Figure 3 As shown, in this embodiment, the limiting post 42 is provided with a protrusion 421 on the side near the limiting hole 211, which abuts against the reset spring 43, and the reset spring 43 abuts between the protrusion 421 and the limiting plate 41.

[0062] The protrusion 421 provides a dedicated contact point for the return spring 43, and the elastic deformation of the spring generates elastic force, which is transmitted to the limiting post 42 through the protrusion 421. This allows the limiting post 42 to remain inserted into the locking groove 112 under the push of the return spring 43 when no external force is applied, thereby enhancing the stability of axial locking and preventing the limiting post 42 from accidentally slipping out and causing locking failure.

[0063] like Figure 4 As shown, the rotating support 1 in this embodiment includes a support base 12 and a rotating base 13, which modularly divides the rotation function. The support base 12 serves as the basic support part, and the rotating base 13 serves as the rotatable movable part; thus, the rotating support 1 has a clear division of labor, which facilitates installation and maintenance.

[0064] The support base 12 is rotatably connected to the support base 12, enabling the support base 12 to rotate relative to the support base 12. This gives the rotating seat 13 the function of rotating relative to the support base 12, meeting the need for flexible angle adjustment during the use of the baby rocker.

[0065] The rotating base 13 is connected to the connecting member 11. The connection between the rotating base 13 and the connecting member 11 can be achieved through methods such as bolt fixing or snap-fit ​​fixing using clips 32. This allows the rotating base 13 to be securely connected to the rocker base 2 via the connecting member 11, ensuring that the entire baby rocker has both rotational flexibility and a stable connection to the base, thus solving the problem of balancing rotation and a stable connection.

[0066] like Figure 4 As shown, in this embodiment, the support base 12 is provided with a rotating shaft 14, the rotating base 13 is provided with a bushing 15, the bushing 15 is provided with a rotating transition cavity 151, the upper end of the rotating transition cavity 151 is provided with a first bearing 152, the lower end of the rotating transition cavity 151 is provided with a second bearing 153, and the end of the bushing 15 near the second bearing 153 is provided with a sealing sleeve 154 to restrict the displacement of the second bearing 153.

[0067] The rotational connection structure is formed by the cooperation of the rotating shaft 14 and the bushing 15, providing a basic framework for the rotation of the rotating seat 13 relative to the support seat 12.

[0068] By providing a rotating transition cavity 151 inside the bushing 15, a space is constructed to accommodate rotating components and ensure smooth rotation; this allows rotating components to be arranged in an orderly manner, reducing friction and interference during rotation.

[0069] The rolling friction characteristics of the first bearing 152 and the second bearing 153 reduce rotational resistance, making the rotation of the upper and lower ends of the rotating seat 13 more flexible and stable, reducing wear, and achieving stable and smooth rotation of the entire rotating seat 13.

[0070] The sealing sleeve 154 is used to prevent the second bearing 153 from shifting; this ensures the stability of the second bearing 153 and avoids affecting the smoothness and reliability of the rotation of the rotating seat 13 due to bearing displacement, thereby solving problems such as jamming and instability that may occur during rotation.

[0071] like Figure 4 As shown, in this embodiment, the rotating shaft 14 is provided with a first limiting part 141 corresponding to the first bearing 152; the rotating shaft 14 is provided with a second limiting part 142 corresponding to the second bearing 153.

[0072] The first limiting part 141 constrains the axial position of the first bearing 152, and the second limiting part 142 constrains the axial position of the second bearing 153; thus preventing the first bearing 152 and the second bearing 153 from moving axially, ensuring that the two bearings are accurately and fixedly positioned on the rotating shaft 14, thereby ensuring the smoothness and reliability of the rotation of the entire rotating seat 13 relative to the support seat 12, and effectively solving problems such as rotation jamming and unevenness caused by bearing displacement.

[0073] like Figure 4 As shown, the bushing 15 in this embodiment is provided with a rotation limiting groove 155, and the support seat 12 is slidably provided with a limiting slider 121. The limiting slider 121 extends into the rotation limiting groove 155 to limit the rotation amplitude of the support seat 12 and the rotating seat 13.

[0074] A rotation limiting groove 155 is constructed on the bushing 15 to define the rotation range boundary of the rotating seat 13 relative to the support seat 12, providing a structural basis for subsequent limiting of the rotation amplitude. The limiting slider 121 has the ability to move along the axial direction of the support seat 12 so as to cooperate with the rotation limiting groove 155 on the bushing 15, ensuring that the limiting slider 121 can flexibly interact with the limiting groove.

[0075] In use, the limiting slider 121 extends into the limiting groove along the axis of the support seat 12 to restrict the support seat 12. When the rotating seat 13 rotates to a certain angle, the limiting slider 121 will touch the end of the rotating limiting groove 155, thereby preventing further rotation. This effectively controls the rotation range of the rotating seat 13, prevents the rotating seat 13 from rotating excessively, ensures the safety of the baby rocker, and avoids problems such as baby discomfort or damage to the rocker due to excessive rotation.

[0076] like Figure 3 and Figure 4 As shown, in this embodiment, the rocking chair base 2 is provided with a buckle groove 23 below the first locking assembly 3. The buckle groove 23 is used to provide a leverage point for pressing the first locking assembly 3.

[0077] By setting a recessed structure on the base to form a specific operating space, a leverage point is provided for pressing the first locking component 3, making it easier for the user to apply force and making the unlocking action easier and more convenient. This solves the problem of inconvenient unlocking operation caused by the position or structure of the first locking component 3, and improves the convenience and user experience of the baby rocker.

[0078] like Figure 2 As shown, the rocking chair base 2 in this embodiment includes a seat 24 and a rocking frame 25. The rocking frame 25 includes a backrest 251 and a seat portion 252, and the seat 24 is fixed to the seat portion 252.

[0079] Specifically, the base functions are modularized, with the rocker arm 25 serving as the main support frame for the rocking function and the human body, and the seat plate 24 providing the specific seating surface; this clear division of labor facilitates design, manufacturing, and installation.

[0080] Based on the human body's sitting posture requirements, the rocker 25 is divided into different areas supporting the back and the seat 252; this better conforms to the curves of the human body and improves the comfort of the infant. The seat 24 is fixed to the seat 252 by bolts or welding to ensure the relative position stability of the seat 24 and the seat 252; this ensures that the seat 24 will not move arbitrarily during use, providing stable and reliable seat support for the infant and solving the problem of the seat 24 easily shifting, affecting safety and comfort.

[0081] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
