[0009] By adopting the above technical solution, when the limit block moves to the opening of the installation groove close to the ground, the limit block covers the opening of the installation groove close to the bottom wall of the support seat, so that the support rod cannot rotate downward, so that the support rod remains horizontal with the ground, thereby improving the stability of the baby crib when in use.

[0010] Optionally, a rotating shaft is provided on the support seat, and the rotating shaft passes through the support seat and the limit block in sequence, the rotating shaft is rotatably connected to the support seat, and the limit block is fixedly connected to the rotating shaft.

[0011] By adopting the above technical solution, the limit block is rotatably connected to the support seat via the rotating shaft, and the position of the limit block is adjusted by controlling the rotation angle of the rotating shaft, thereby achieving adjustment of the installation state of the baby crib.

[0012] Optionally, the adjustment assembly includes a handle, and the handle is arranged at an end of the rotating shaft away from the limiting block.

[0033] The embodiment of the present application discloses a base.

[0034] Example 1

[0035] Reference Figure 1 and Figure 2 A base includes a support seat 1 and a plurality of support rods 2, the plurality of support rods 2 are arranged around the side wall of the support seat 1 with the axis of the support seat 1 as the center, the end wall of the support rod 2 is movably connected to the support seat 1, and a support foot 21 is arranged at one end of the support rod 2 away from the support seat 1, the support foot 21 extends in the direction of the ground, and the base is supported on the ground by a support angle; the base also includes a limit assembly 3 and an adjustment assembly 4, the limit assembly 3 has a locking position and a movable position when in use, and the limit assembly 3 can switch back and forth between the locking position and the movable position, and the limit assembly 3 can limit and fix the support seat 1 and the plurality of support rods 2 when in the locking position state, so that the plane formed by the plurality of support rods 2 when unfolded remains level with the ground, thereby improving the stability of the base when in use; the adjustment assembly 4 can control the limit assembly 3 to switch back and forth between the locking position and the movable position.

[0036] When the crib is in use, the base is in the unfolded state, and the user adjusts the limit assembly 3 to the locked position through the adjustment assembly 4 to limit the movement of the support rod 2, thereby improving the stability of the crib when in use; when the crib is to be stored, the user adjusts the state of the limit assembly 3 by controlling the adjustment assembly 4, so that the limit assembly 3 is unlocked, the support rod 2 and the support seat 1 are both in a movable state, and then the support rod 2 is controlled to be folded and retracted in a specified direction for storage, so that the crib is easy to fold and store while also having high stability, further improving the safety and use effect of the crib.

[0037] Reference Figure 1 and Figure 2A plurality of mounting grooves 11 matching the ends of the support rods 2 are provided on one side of the support seat 1 close to the ground, and the side walls of the plurality of mounting grooves 11 close to the outer edge of the support seat 1 are connected to the outside, and the plurality of mounting grooves 11 are arranged one-to-one with the plurality of support rods 2, and the ends of the side walls in the length direction of the support rods 2 are buckled into the mounting grooves 11, and the ends of the side walls in the length direction of the support rods 2 are hinged to the inner walls of the mounting grooves 11; in this embodiment, four support rods 2 are provided; when the support rods 2 are all in a horizontal state, the plane figure formed by connecting the end points of the four support rods 2 away from one end of the support seat 1 is a rectangle, and the base is in an unfolded state.

[0038] Reference Figure 2 The limit assembly 3 includes a limit block 31, which is movably arranged on the side of the support seat 1 close to the ground, and the openings of the plurality of mounting slots 11 close to the ground are all located on the movable path of the limit block 31. The limit block 31 includes a locking position and a movable position when in use, and the limit block 31 can switch back and forth between the locking position and the movable position. When the limit block 31 is in the locking position, the support rod 2 can be clamped between the limit block 31 and the support seat 1, and the movable direction of the support rod 2 is limited, thereby reducing the possibility of displacement of the support rod 2 due to shaking, and the possibility of deformation of the shape of the base when in use.

[0039] Reference Figure 2 The support base 1 is provided with a rotating shaft 32, which is sequentially passed through the support base 1 and the limit block 31, and the rotating shaft 32 is rotatably connected to the support base 1. In the present embodiment, the rotating shaft 32 is colinearly arranged with the axis of the support base 1 in the vertical direction, and the limit block 31 is fixedly connected to the rotating shaft 32; the rotating shaft 32 drives the limit block 31 to rotate when rotating, and when the limit block 31 moves to the opening of the mounting groove 11 on the side close to the ground, the limit block 31 covers the opening of the mounting groove 11 on the bottom wall of the support base 1, so that the support rod 2 cannot rotate toward the direction close to the axis of the support base 1, so that the support rod 2 can maintain a horizontal state with the ground, thereby improving the stability of the baby bed when in use.

[0040] Reference Figure 2 and Figure 3The adjusting assembly 4 includes a handle 41, which is arranged at one end of the rotating shaft 32 away from the limit block 31, and the handle 41 is movably connected to the end wall of the rotating shaft 32; in this embodiment, a connecting shaft 42 is arranged at the connection between the handle 41 and the rotating shaft 32, and a connecting ring passes through the side wall end of the rotating shaft 32 in the length direction, and the outer wall of the connecting ring is rotatably connected to the rotating shaft 32, and both ends of the connecting shaft 42 in the length direction are movably connected to the handle 41, so that the handle 41 can be reciprocated and folded in the direction close to or away from the upper surface of the support seat 1; a concave is arranged on one side of the support seat 1 away from the limit block 31 There is a receiving groove 12 adapted to the handle 41, and the receiving groove 12 can be used for the handle 41 to be buckled into; when there is no need to adjust the state of the limit block 31, the handle 41 is buckled into the receiving groove 12, thereby reducing the possibility of scratching the baby due to the handle 41 protruding from the support seat 1, making the base flatter when in use; when the position of the limit block 31 needs to be adjusted, the handle 41 is bent so that the handle 41 protrudes from the support seat 1 and the rotating shaft 32 and the limit block 31 are driven to rotate by the wave handle 41, so as to improve the convenience of the user in adjusting the use state of the limit block 31.

[0041] Reference Figure 3 The handle 41 is provided with a plurality of gripping grooves 43 for the user's fingers to buckle into, so as to facilitate the user to lift and control the handle 41, thereby reducing the possibility of the user's hand slipping when adjusting the position of the limit block 31 using the handle 41.

[0042] Reference Figure 2 A protrusion 33 is protruded from one side of the limit block 31 close to the support seat 1, and a limit groove 13 adapted to the protrusion 33 is opened at one end of the support seat 1 close to the limit block 31, and the protrusion 33 can reciprocate in the limit groove 13; when the limit assembly 3 is in the locking position, the protrusion 33 abuts against the end wall at one end of the extension direction of the limit groove 13; when the limit assembly 3 is in the active position, the protrusion 33 abuts against the end wall at the other end of the extension direction of the limit groove 13.

[0043] Reference Figure 2 The moving distance of the protrusion 33 is limited by the end wall of the limiting groove 13, thereby realizing the limitation of the rotation angle of the rotating shaft 32 and the limiting block 31; when the limiting block 31 is adjusted between the locking position and the free position, the rotating shaft 32 is controlled to rotate until the protrusion 33 abuts against the end wall of one end of the limiting groove 13, and the user does not need to control the rotation angle of the rotating shaft 32 by himself, thereby improving the convenience of the user in adjusting the state of the limiting component 3.

[0044] Reference Figure 2A torsion spring 34 is provided at the connection between the outer surface of the rotating shaft 32 and the support seat 1. The torsion spring 34 is coaxially sleeved on the rotating shaft 32. One end of the torsion spring 34 is fixedly connected to the support seat 1, and the other end is fixedly connected to the limit block 31; the torsion spring 34 realizes a damping connection between the rotating shaft 32 and the support seat 1. The rotating shaft 32 will only rotate relative to the support seat 1 when a large external force is applied, thereby reducing the possibility that the limit block 31 and the rotating shaft 32 will shift due to unintentional external shaking, resulting in a change in the state of the limit assembly 3, thereby further improving the safety of the baby bed when in use.

[0045] Reference Figure 1 A first balancing foot 5 is movably provided on the support seat 1, and the first balancing foot 5 can reciprocate in a direction close to or away from the ground, and the ground can be abutted by the first balancing foot 5; when the base is in the unfolded state, the position of the first balancing foot 5 is adjusted until the first balancing foot 5 abuts against the ground. By providing the first balancing foot 5, the contact area between the base and the ground can be increased when the baby crib is in use, and the stability of the base is improved, thereby improving the safety of the baby crib when in use.

[0046] The implementation principle of Example 1 of the present application is as follows: when the baby crib is in the storage state, the limit block 31 is in the active position, the plurality of support rods 2 are in the direction close to the axis of the support seat 1, and the base is in a folded state for easy storage; when in use, the support seat 1 is controlled to move in the direction close to the ground until the plurality of support rods 2 are parallel to the ground, and the handle 41 is rotated to drive the limit block 31 to rotate; when the limit block 31 moves to the opening of the mounting groove 11 on the side close to the ground, the limit block 31 covers the opening of the mounting groove 11 on the bottom wall of the support seat 1, so that the support rod 2 cannot rotate in the direction close to the axis of the support seat 1, and the limit block 31 is switched from the active position to the locked position, so that the support rod 2 can maintain a horizontal state with the ground, thereby improving the stability of the baby crib when in use; then the handle 41 is bent so that the handle 41 is buckled into the interior of the accommodating groove 12, thereby reducing the possibility of scratching the baby due to the handle 41 protruding from the support seat 1;

[0047] When the position of the limit block 31 needs to be adjusted, the handle 41 is moved so that the handle 41 protrudes from the support seat 1 and the rotating shaft 32 and the limit block 31 are driven to rotate by the wave handle 41, so as to improve the convenience of the user in adjusting the use status of the limit block 31.

[0048] Example 2

[0049] Reference Figure 4The difference between Example 2 and Example 1 is that a limiting column 14 is protruded from one end of the support seat 1 close to the ground, and an arc groove 311 adapted to the limiting column 14 is penetrated and opened on the limiting block 31; the cross-sectional profile of the arc groove 311 is arc-shaped, and the center of the arc is located on the central axis of the rotating shaft 32. When the support seat 1 and the limiting block 31 are assembled, the limiting column 14 is buckled into the arc groove 311, and the limiting column 14 can slide back and forth along the extension direction of the arc groove 311; when the limiting assembly 3 switches back and forth between the locking position and the free position, the side walls of the limiting column 14 respectively abut against the end walls at both ends of the extension direction of the arc groove 311, and the moving distance of the limiting column 14 is limited by the end walls of the arc groove 311, thereby realizing the limitation of the rotation angle of the rotating shaft 32 and the limiting block 31.

[0050] In a preferred implementation manner of this embodiment, the limit column 14 adopts a bolt, and the limit column 14 is threadedly connected to the side of the support seat 1 close to the ground, so as to facilitate the installation of the limit column 14 by the staff, and a gasket 141 is provided at the connection between the end of the bolt and the side of the limit block 31 away from the support seat 1. The gasket 141 can protect the limit block 31, increase the contact area between the limit block 31 and the end of the bolt, reduce the possibility of the limit column 14 scratching the limit block 31 during movement, and extend the service life of the limit block 31.

[0051] Example 3

[0052] Reference Figure 5 , the difference between Example 3 and Example 1 is that the base includes two balancing rods 6, and the two balancing rods 6 are symmetrically arranged with the axis in the length direction of the base as the center; the balancing rod 6 is arranged between two adjacent support rods 2, one end of the balancing rod 6 is movably connected to the middle section of one of the balancing rods 6, and the other end is movably connected to the adjacent balancing rod 6, so that a triangular structure can be formed between the adjacent support rods 2 and the balancing rod 6, the balancing rod 6 includes a first mounting rod 61, a second mounting rod 62 and a balancing seat 63, the first mounting rod 61 and the second mounting rod 62 are connected by the balancing seat 63, the first mounting rod 61 and the second mounting rod 62 are movably arranged with the balancing seat 63, when the plurality of support rods 2 are parallel to the ground, the first mounting rod 61 and the second mounting rod 62 are located in the same straight line, so that a triangular stable structure is formed between the adjacent support rods 2 and the balancing rod 6, thereby improving the stability of the base; when the support rods 2 are folded, the first mounting rod 61 and the second mounting rod 62 are in a folded state, reducing the volume of the baby bed when stored and improving the convenience of the baby bed when stored.

[0053] Based on the same design concept, the present application also discloses a baby crib.

[0054] Reference Figure 6A baby bed includes a base 8 and a fence 7, which are movably connected to each other; the fence 7 includes a plurality of connecting frames 71 that are movably connected in sequence; the connecting frame 71 is movably connected to an end of a support rod 2 away from a support seat 1; when the connecting frame 71 is perpendicular to the base 8, an area for a baby to rest is formed between the base and the connecting frame 71.

[0055] The base 8 includes an expanded state and a folded state when in use. When the plurality of support rods 2 are parallel to the ground, the base is in an expanded state, the fence 7 is perpendicular to the upper surface of the base, and a space for the baby to rest can be enclosed between the base 8 and the fence 7, thereby completing the assembly of the crib. When the crib is stored, the plurality of support rods 2 are folded so that the angle between the support rods 2 and the upper surface of the support seat 1 changes from a straight angle to an obtuse angle. The connecting frame 71 also folds accordingly to adapt to the changes in the support rods 2, so that the base 8 and the fence 7 are both in a folded state, thereby reducing the volume of the crib when stored and improving the convenience of the crib when stored or carried.
