[0037] The utility model is described in further detail below in conjunction with the accompanying drawings.

[0038] Those skilled in the art will readily come up with other embodiments of the utility model after considering the specification and practicing the utility model disclosed herein. This application is intended to cover any variation, use or adaptation of the utility model, which follows the general principles of the utility model and includes common knowledge or customary technical means in the art that are not disclosed in this disclosure. The specification and examples are to be regarded as exemplary only, and the true scope and spirit of the utility model are indicated by the claims.

[0039] like Figure 1As shown, a locking structure comprises a male module 1 and a female module 2 which are matched with each other, wherein an arc-shaped latch 3 is rotatably connected in the male module 1; the interior of the male module 1 is a hollow cavity; the middle part thereof comprises a first plane 11, a second plane 12, a third plane 13 and a fourth plane 14 which are adjacent to each other, and a fifth plane 15 and a sixth plane 16 which close the upper and lower ends; the first plane 11 is provided with a first through hole 111, a second through hole 112 and a third through hole 113 from top to bottom in sequence; the second plane 12 is provided with a semi-arc sliding groove 121; the third plane 13 is provided with a second screw hole 131; the first plane 11 faces the female module 2; the The female module 2 is provided with a fourth through hole 21, a fifth through hole 22 and a sixth through hole 23 from top to bottom; the height of the fifth through hole 22 matches that of the second through hole 112; the arc-shaped latch 3 includes a sliding body 31, a connecting portion 32 and an operating portion 33; the sliding body 31 is in an arc shape, with a connecting portion 32 on one side thereof and the sliding groove 121 extending outward, and an operating portion 33 on the other side of the connecting portion 32; the operating portion 33 adopts a circular structure; the operating portion 33 is pushed along the path of the sliding groove 121, and the sliding body 31 extends out of the second through hole 112 and is embedded in the fifth through hole 22. In this embodiment, the first through hole 111 and the third through hole 113 are provided on the upper and lower sides of the third through hole 113, and the opening area thereof is larger than the second screw hole 131, and its main function is to insert the screw into the first through hole 111 and the third through hole 113, and then the screw passes through the second screw hole 131 to fix the male module 1 with the crib fence. The opening size of the second through hole 112 matches the size of the sliding body 31, so that the sliding body 31 can extend out of the second through hole 112 after making an arc swing through thrust, and extend into the mother module 2 to lock the crib guardrail. The fourth through hole 21 and the sixth through hole 23 of the mother module 2 are arranged on the upper and lower sides of the fifth through hole 22. The fourth through hole 21 and the sixth through hole 23 are screw holes for fixing the mother module 2 to the crib fence. The opening size of the fifth through hole 22 matches the size of the sliding body 31, and can accommodate the end of the sliding body 31. The arc-shaped latch 3 makes a circular motion in the male module 1, thereby avoiding the traditional locking structure in which the latch is fixed or separated by lateral motion. Compared with simple lateral motion, the circular motion can reduce the collision between the crib fences, thereby improving the safety and stability of the crib and increasing its service life.

[0040] Furthermore, the end of the sliding groove 121 facing the female module 2 is provided with a downwardly recessed stop groove 122. In this embodiment, the operating portion 33 is pushed along the trajectory of the sliding groove 121, and the sliding body 31 passes through the second through hole 112 and the fifth through hole 22 from the accommodating cavity of the male module 1 in sequence through the connecting portion 32, and reaches the accommodating cavity of the female module 2. Due to the effect of gravity, the sliding module will slightly fall into the stop groove 122. Since the sliding body 31 is hook-shaped or arc-shaped, the first side plate of the crib and the second side plate of the crib can be tightly connected.

[0041] like Figure 2 , 3 As shown, further, the fourth plane 14 and the locking structure are detachable; the fourth plane 14 is provided with a first screw hole 141, a first limiting hole 142 and a first elastic buckle 143, the first screw hole 141 is close to the third plane 13, and the first elastic buckle 143 is close to the first plane 11; the second plane 12 is provided with a first bolt 123 matching the first screw hole 141, and a first limiting column 124 matching the first limiting hole 142; the first plane 11 is provided with a first clamping groove 125 matching the first elastic buckle 143. In this embodiment, in order to prevent the sliding body 31 from shaking during use, the structure of the male module 1 is improved. The outer shell of the male module 1 is divided into two parts, the fourth plane 14 is an openable shell, and the other planes are integrated shells. The fourth plane 14 is encapsulated by matching the first screw hole 141, the first elastic buckle 143, the first bolt 123 and the first clamping groove 125. The first limiting column 124 and the first limiting hole 142 are used to connect the arc-shaped latch 3. The arc-shaped latch 3 is sleeved on the first limiting column 124, and the first limiting column 124 is then pressed into the first limiting hole 142. The arc-shaped latch 3 has a relatively stable fixed position in the male module 1. The first limiting column 124 is arranged closer to the side of the first plane 11, which can provide more space for the sliding body 31 to rotate and adapt to sliding bodies 31 of more shapes.

[0042] like Figure 4 As shown, further, the shape of the sliding body 31 is "V"; a second limiting hole 311 is provided at the front end of the lower side thereof, a third threaded hole 312 is provided on the sliding body 31, a thread is provided at the end area of ​​the connecting portion 32, and the sliding body 31 and the connecting portion 32 are detachably connected. In this embodiment, the sliding body 31 adopts a V-shape, which not only ensures that the head of the sliding body 31 can easily move back and forth between the male module 1 and the female module 2, but also reduces the manufacturing cost and avoids conflicts with other structures in the male module 1.

[0043] like Figure 5 , 6As shown, further, the side surfaces of the fourth through hole 21 and the sixth through hole 23 are provided with second latching grooves 24; the female module 2 is also equipped with a latch 25; Fig.10 As shown, the buckle 25 includes a covering body 251 that matches the size of the fourth through hole 21 and the sixth through hole 23, and a second elastic buckle 252 that extends vertically to one side, and the second elastic buckle 252 matches the second snap-in slot 24. In order to ensure the aesthetics of the mother module 2 after it is installed on the bed frame of the baby bed, the screw holes of the fourth through hole 21 and the sixth through hole 23 are covered. In addition, a buckle 25 is used, and its shape is designed to be consistent with the fourth through hole 21 and the sixth through hole 23, and then the elastic buckle set on the side is buckled with the snap-in slot to ensure the flatness of the surface as much as possible and improve the aesthetics.

[0044] like Fig.11 , 12 As shown, further, a limit spring 17 is provided in the male module 1, one end of which is sleeved on the connecting portion 32, and the other end is sleeved on the first limit column 124. In this embodiment, in order to prevent the sliding body 31 from rocking back and forth in the sliding groove 121, a limit spring is installed between the connecting portion and the first limit column. In the locked state and the unlocked state, the distance between the connecting rod and the male end of the limit column is different, and the tension generated by the limit spring is different, which plays a limiting role on the sliding body.

[0045] like Figure 7 As shown, further, a baby crib frame 4 includes a first side 41 and a third side 43 that are parallel and symmetrical to each other, and a second side 42 and a fourth side 44 that are parallel to each other. The first side 41, the second side 42, the third side 43 and the fourth side 44 form a completed baby crib frame 4. Any of the above-mentioned locking structures for baby cribs are provided on the first side 41, the second side 42, the third side 43 and the fourth side 44. In this embodiment, a baby crib frame 4 is provided, which adopts a traditional four-side structure and is combined with the locking structure described in this application to lift and lower the first side 41 and the third side 43.

[0046] like Figure 8, as shown in FIG. 9, further, the first surrounding edge 41 and the third surrounding edge 43 are in a planar shape, the second surrounding edge 42 and the fourth surrounding edge 44 are in a "U" shape, and the portions vertically extending from both sides thereof are butted against the first surrounding edge 41 and the third surrounding edge 43; first notches 45 for accommodating the male module 1 are formed at the upper left corner and the upper right corner edges of the first surrounding edge 41 and the third surrounding edge 43; second notches 46 for accommodating the female module 2 are also formed on the second surrounding edge 42 and the fourth surrounding edge 44; the first surrounding edge 41 and the third surrounding edge 43 are detachably connected to the second surrounding edge 42 and the fourth surrounding edge 44 through a locking structure. In this embodiment, the first notches 45 are formed at the upper left corner and the upper right corner of the first surrounding edge 41 and the third surrounding edge 43. The first notches 45 are right-angled and are sized to match the male module 1, so that the male module 1 can be embedded in the notches, keeping the entire surrounding edge in a complete quadrilateral shape and improving the aesthetics of the fence. The edges of the second surrounding edge 42 and the fourth surrounding edge 44 have bent extension portions in a "U" shape, and second notches 46 for accommodating the female module 2 are also formed above, so that the female module 2 is embedded therein, also keeping the edges of the second surrounding edge 42 and the fourth surrounding edge 44 flat. With such a setting, not only can the aesthetics of the crib frame 4 be improved, but the flat structure can also improve the overall stability of the crib.

[0047] It should be understood that the present utility model is not limited to the exact structure that has been described above and shown in the drawings, and various modifications and changes can be made without departing from its scope.
