It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting the present utility model.

[0035] It can be understood that the term "one" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in other embodiments, the number of the element can be multiple. The term "one" should not be construed as limiting the quantity.

[0036] Refer to Figures 1 to 5, in the first aspect of the embodiment of the present application, a crib railing assembly 200 is provided, which includes a locking frame 10, an inner plug 20, a button 30, a first railing member 40 and a second railing member 50. The locking frame 10 has a locking groove 101, and the locking groove 101 has a longitudinal opening 102 and two transverse openings symmetrically distributed on both sides of the longitudinal opening 102. The longitudinal opening 102 is located directly below, and the two transverse openings are respectively located on the left and right sides of the locking frame 10. The locking frame 10 is provided with two locking pin grooves 103, and the two locking pin grooves 103 are symmetrically and obliquely distributed with respect to the center line of the longitudinal opening 102, that is, symmetrically and obliquely distributed on the left and right sides of the locking frame 10. The inclination direction is: gradually approaching the longitudinal opening 10 from the end far away from the transverse opening to the opposite end. A locking pin 11 is embedded in the locking pin groove 103.

[0037] The inner plug 20 is embedded in the locking groove 101 and is located between the two locking pin grooves 103. The inner plug 20 has a movable groove 201. The opening direction of the movable groove 201 is the same as the opening direction of the locking groove 101, and mounting blocks 21 are symmetrically arranged in the movable groove 201 with respect to the center line of the longitudinal opening. Two mounting blocks 21 are respectively connected to the locking pins 11 on both sides through elastic members 22. In this way, the locking pins 11 can move directionally in the groove-shaped channel formed by the movable groove 201 and the locking pin grooves 103 to compress the elastic members 22 or move reversely by being rebounded by the elastic members 22.

[0038] The first railing member 40 and the second railing member 50 are respectively inserted into the movable groove 201 from the two transverse openings, and are respectively hinged to the locking frame 10 through a hinge shaft 41, and are respectively provided with driving grooves 401 that cooperate with the two locking pins 11. The extending direction of the driving groove 401 is the same as the extending direction of the locking pin groove 103. At the same time, an avoidance notch 402 is opened on the upper groove wall of the driving groove 401, and the hinge shaft 41 is located outside the driving groove 401. The upper groove wall refers to the groove wall of the driving groove 401 away from the longitudinal opening 102, and the outside of the locking frame 10 refers to the side of the locking frame 10 close to the transverse opening.

[0039] The button 30 is inserted into the locking groove 101 from the longitudinal opening 102, and is provided with driving inclined surfaces 31 that cooperate with the two locking pins 11 to be able to directionally drive the locking pins 11 to disengage the locking pins 11 from the driving groove 401 at the avoidance notch 402. At the same time, the button 30 is elastically connected to the locking frame 10.

[0040] Thus, by pressing the button 30 upward, the driving inclined surface 31 on the button 30 can drive the locking pin 11 to move along the direction of the driving groove 401 (i.e., the direction of the locking pin groove 103). When it moves to the avoidance notch 402, the unlocking of the first fence member 40 and the second fence member 50 is completed. At this time, the first fence member 40 and the second fence member 50 can rotate around the hinge axis 41 as the rotation center, and the mutually separated ends move closer to each other above (above is the direction away from the longitudinal opening 102) to complete the folding. It should be noted that even after folding, the locking pin 11 is still restricted within the locking pin groove 103. When the button 30 moves in the reverse direction to reset, the locking pin 11 moves outward and presses against the lower groove wall of the driving groove 401 to reset, driving the first fence member 40 and the second fence member 50 to unfold and reset. The operation is simple. At the same time, the first fence member 40 and the second fence member 50 move in a directional manner during folding and unfolding, and there will be no situation of tilting outwards or inwards like in the conventional folding process. In addition, compared with the conventional direct hinge connection method, the cooperation of the locking frame 10, the inner plug 20, and the button 30 has better locking stability and better structural stability, and it is not prone to fatigue damage problems after long-term use, and has a longer service life.

[0041] In one embodiment, the locking frame 10 is provided with a guiding groove 104 at the center line facing the longitudinal opening 102, and at the same time, the guiding groove 104 vertically penetrates the two groove walls of the locking groove 101. The inner plug 20 is provided with a guiding notch 202 facing the guiding groove 104. A guiding member 12 is arranged in the guiding groove 104. At the same time, both ends of the guiding member 12 protruding from the first fence member 40 and the second fence member 50 are connected with a linkage member 13. One end of the two linkage members 13 away from the guiding member 12 is respectively hinged to the first fence member 40 and the second fence member 50 through a positioning shaft 14, and the positioning shaft 14 is located between the driving groove 401 and the hinge axis 41 and is away from the longitudinal opening 102 relative to the hinge axis 41. In addition, the linkage member 13 is configured such that when the driving inclined surface 31 drives the locking pin 11 away from the bottom of the driving groove 401, the outer ends of the first fence member 40 and the second fence member 50 move in the direction away from the longitudinal opening 102, and at the same time, the inner ends of the first fence member 40 and the second fence member 50 move along the guiding groove 104 towards the longitudinal opening 102 along with the guiding member 12. Thus, through the cooperation of the linkage member 13, the guiding member 12, and the guiding groove 104, a further guiding effect can be provided, making the movement of the first fence member 40 and the second fence member 50 more stable and with a high precision of the movement direction during the folding or unfolding of the first fence member 40 and the second fence member 50. Among them, the linkage member 12 can be a semi-circular ring buckle or an arc-shaped buckle.

[0042] In one embodiment, the button 30 includes a pressing portion 32 and two driving portions 33 symmetrically arranged on the same side of the pressing portion 32. The driving portions 33 are respectively clamped on both sides of the first fence member 40 and the second fence member 50. At the same time, the driving inclined surface 31 is located at one end of the driving portion 33 away from the pressing portion 32. A reset elastic member 34 is arranged in the pressing portion 32 opposite to the driving portion 33. One end of the reset elastic member 34 close to the longitudinal opening 102 abuts against the end of the pressing portion 32 away from the driving portion 33, and the other end of the reset elastic member 34 is connected to the locking frame 10 through a limiting member (not shown in the figure). The limiting member penetrates through the button 30 and the locking frame 10 at the same time, and the reset elastic member 34 extends along the direction of the longitudinal opening 102, so that when the button 30 moves in the opposite direction of the pressing direction, an additional elastic boost can be provided by the reset elastic member 34, making it easier and more convenient to expand the fence.

[0043] In the present application, both the elastic member 22 and the reset elastic member 34 are implemented as springs.

[0044] Further preferably, at least two guiding ribs 35 are arranged in parallel along the direction of the longitudinal opening 102 on the pressing portion 32. At the same time, a guiding notch 105 matching the guiding ribs 35 is arranged at one end of the locking frame 10 close to the longitudinal opening 102, so that further guiding assistance can be provided to the first fence member 40 and the second fence member 50 through the cooperation of the guiding ribs 35 and the guiding notch 105. Generally, two guiding ribs 35 are arranged, and the two guiding ribs 35 are symmetrically distributed relative to the guiding groove 104, which is easy to process and has good guiding stability.

[0045] A second aspect of the embodiment of the present application provides a crib bottom frame assembly 300, referring to Figures 6 to 10 , including a base 60 and four bottom frame connecting members 70. The base 60 has a sliding cavity, and a base slider 61 that can slide directionally is arranged in the sliding cavity of the base 60. The base slider 61 is provided with a wedge-shaped groove 601, and base locking pins 62 are symmetrically arranged on both sides of the base slider 61 in the sliding direction of the base slider 61 in the wedge-shaped groove 601. The two base locking pins 62 are elastically connected, and the wedge-shaped groove 601 is configured to: when the base slider 61 moves in a predetermined direction (such as upward), it can drive the two base locking pins 62 to approach each other, and when moving in the opposite direction, it can drive the two base locking pins 62 to move away from each other based on the rebound effect.

[0046] One end of each of the four chassis connectors 70 is symmetrically inserted into the sliding cavity and is respectively hinged to the base 60 through a base rotating shaft 71. At the same time, the other ends of the four chassis connectors 70 are respectively used to connect the four columns 100 of the crib. One end of the chassis connector 70 located in the sliding cavity is correspondingly provided with meshing gears 72. At the same time, the four chassis connectors 70 are respectively defined as a first connector 711, a second connector 712, a third connector 713, and a fourth connector 714. Among them, the gears 72 on the first connector 711 and the second connector 712 mesh with each other, and the gears 72 on the third connector 713 and the fourth connector 714 mesh with each other. In addition, the first connector 711 and the third connector 713 are respectively provided with locking grooves 701 that cooperate with the base locking pins 62, or the second connector 712 and the fourth connector 714 are respectively provided with locking grooves 701 that cooperate with the base locking pins 62, so that when the two base locking pins 62 move away from each other, they can be inserted into the locking grooves 701, and when they move closer to each other, they can disengage from the locking grooves 701. In this way, the base slider 61 can be directly lifted to make the two base locking pins 62 move closer to each other and disengage from the locking grooves 701 to complete unlocking. At this time, the first connector 711 and the second connector 712, as well as the third connector 713 and the fourth connector 714, can be folded through the gear meshing relationship. When the first connector 711 and the second connector 712, as well as the third connector 713 and the fourth connector 714 rotate in the reverse direction and reset, the two base locking pins 62 will be inserted into the locking grooves 701 again under the rebounding action to complete the locking of the chassis. The operation is convenient. At the same time, based on the meshing relationship between each other, whether it is during the folding process or the unfolding process, the rotation directions of the four chassis connectors 70 are fixed, the operation is smooth, and the structural stability is good. Especially, it is not easy to appear the phenomenon of fatigue damage after long-term use.

[0047] In one embodiment, a sliding opening is provided at the top of the sliding cavity. A base cover plate 63 is fixedly provided at the sliding opening. At the same time, an avoidance hole 602 is opened on the base cover plate 63, and the base slider 61 is provided with a slider handle 611 that cooperates with the avoidance hole 602, so as to limit the base slider 61 in the sliding cavity, facilitate lifting the base slider 61 through the slider handle 611, and it is not easy to disengage from the sliding cavity.

[0048] In one embodiment, the crib bottom frame assembly 300 further includes four reinforcing connectors 80, such as connecting rods or connecting tubes. Four of the reinforcing connectors 80 are respectively located below the four bottom frame connectors 70. One end of each of the four reinforcing connectors 80 is respectively hinged to the base 60, and the other end of each is respectively hinged to the upright column 100. Thus, the structural stability of the crib bottom frame, that is, the structural stability of the lower part of the crib, can be further improved through the reinforcing connectors 80.

[0049] A third aspect of the embodiments of the present application provides a crib, which combines Figures 1 - 10 , and includes four upright columns 100, the aforementioned crib railing assembly 200, and the aforementioned crib bottom frame assembly 300. The four upright columns 100 extend in parallel and side by side, and form a virtual quadrilateral in the cross-sectional direction. The crib railing assembly 200 and the crib bottom frame assembly 300 are respectively connected to both ends of the four upright columns 100. The crib railing assembly 200 and the crib bottom frame assembly 300 have been elaborated in detail above.

[0050] In one embodiment, the locking frame 10 is provided with a guide groove 104 at the center line facing the longitudinal opening. At the same time, the guide groove 104 vertically penetrates the two groove walls of the locking groove 101, and the inner plug 20 is provided with a guide notch 105 facing the guide groove 104. A guide member 12 is arranged in the guide groove 104. The guide member 12 is respectively connected with linkage members 13 at both ends protruding from the first railing member 40 and the second railing member 50. The other ends of the two linkage members 13 are respectively hinged to the adjacent first railing member 40 and second railing member 50 through positioning shafts 14. The positioning shafts 14 are located between the driving groove 401 and the hinge shaft 41, and are relatively far from the longitudinal opening 102 with respect to the hinge shaft 41. The linkage member 13 is configured such that when the driving slope 31 drives the locking pin 11 away from the bottom of the driving groove 401, the outer ends of the first railing member 40 and the second railing member 50 move away from the longitudinal opening 102, and the inner ends of the first railing member 40 and the second railing member 50 move along the guide groove 104 toward the longitudinal opening 102 following the guide member 12. Thus, the guiding effect can be further provided through the cooperation of the linkage member 13, the guide member 12, and the guide groove 104. When the first railing member 40 and the second railing member 50 are folded or unfolded, the movement of the first railing member 40 and the second railing member 50 is more stable, and at the same time, the accuracy of the movement direction is high. The linkage member 13 can be a semi-circular ring buckle or an arc-shaped buckle.
