[0039] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments. However, the following embodiments are only the preferred embodiments of the present utility model, not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative labor all belong to the protection scope of the present utility model. The experimental methods in the following embodiments are all conventional methods unless otherwise specified. The materials, reagents, etc. used in the following embodiments can all be obtained from commercial channels unless otherwise specified.

[0040] As Figures 1 - 15 shown, the present utility model provides a baby crib that is convenient for folding and storing, including a fence, a chassis 2 and two groups of brackets 3 arranged in sequence from top to bottom. The fence includes two U-shaped surrounding rods 1. The U-shaped surrounding rods 1 have a horizontally unfolded use state and a vertically folded storage state. Each group of brackets 3 includes two support rods 31. The two support rods 31 have a use state of being unfolded in a V-shape and a vertically folded storage state. The baby crib also includes two first support members 5, a first locking mechanism 7, two second support members 6, two side tubes 4 and a second locking mechanism 8;

[0041] Both ends of the two U-shaped surrounding rods 1 are respectively hinged to connect the first support members 5, and the two U-shaped surrounding rods 1 are symmetrically arranged;

[0042] The first locking mechanism 7 is used to lock and fix the two U-shaped enclosing rods 1 in the horizontally unfolded use state;

[0043] Each second support member 6 is located directly below a first support member 5. Second support members 6 are fixedly provided at both ends of the chassis 2. A set of brackets 3 is provided on each second support member 6, and each support rod 31 is hingedly connected to the second support member 6;

[0044] Each side tube 4 (for supporting the fence) is located between a first support member 5 and a second support member 6, and the two side tubes 4 are arranged in parallel;

[0045] The second locking mechanism 8 is used to lock and fix the two support rods 31 of the bracket 3 in the herringbone unfolded use state;

[0046] When it is necessary to store and fold the crib, by adjusting the first locking mechanism 7, it no longer locks and fixes the two U-shaped enclosing rods 1 in the horizontally unfolded use state, so that the two U-shaped enclosing rods 1 are changed from the horizontally unfolded use state to the vertically folded storage state. At the same time, by adjusting the second locking mechanism 8, it no longer locks and fixes the two support rods 31 of the bracket 3 in the herringbone unfolded use state, so that the two support rods 31 of each set of brackets 3 can be changed from the herringbone unfolded use state to the vertically folded storage state, that is, the folding and storage of the crib fence and the bracket 3 are completed quickly, reducing the occupied space when not in use and increasing the activity area of people indoors.

[0047] Specifically, the specific structures and working principles of the first locking mechanism 7 and the second locking mechanism 8 are as follows:

[0048] As Figure 1 、 Figure 2 、 Figure 3 and Figure 6As shown in the figure, the first locking mechanism 7 includes two first rotating plates 75, a first limiting rod 78, a second elastic member 73, a first slider 74, a guide rod 76, a first elastic member 71, and a first pushing plate 72. The first pushing plate 72 faces the second supporting member 6. Both ends of the two U-shaped surrounding rods 1 are fixedly connected to a first rotating plate 75 respectively. The two first rotating plates 75 are rotatably arranged concentrically on one side of the first supporting member 5. A notch 77 adapted to the cross-sectional size of the first limiting rod 78 is formed on the outer edge of the first rotating plate 75. A first guiding groove 751 is formed on the first rotating plate 75. The guide rod 76 is fixed to one side of the first supporting member 5 and is located in the first guiding groove 751 (through the arrangement of the guide rod 76 and the first guiding groove 751, a certain guiding effect is exerted on the rotation of the first rotating plate 75, making the rotation of the first rotating plate 75 smoother and more stable). When the two notches 77 coincide, the two first guiding grooves 751 are symmetrically arranged along the connection line between the notch 77 and the axis of the first rotating plate 75 (enabling the two first rotating plates 75 to rotate towards each other, thereby completing folding and storage). The second elastic member 73 is fixedly installed on the inner wall of the first supporting member 5. One end of the second elastic member 73 is fixedly connected to the first slider 74. The end of the first slider 74 facing away from the second elastic member 73 is fixedly connected to the first limiting rod 78. The first limiting rod 78 movably penetrates the first supporting member 5. The first elastic member 71 perpendicular to the second elastic member 73 is fixedly connected to the inner wall of the first supporting member 5. One end of the first elastic member 71 is fixedly connected to the first pushing plate 72. The first pushing plate 72 movably penetrates the first supporting member 5. The contact surface between the first pushing plate 72 and the first slider 74 is an inclined surface (a long groove is formed on the first pushing plate 72 to ensure that the first limiting rod 78 does not interfere with or block the first pushing plate 72 during the pushing process). When the first limiting rod 78 is located in the notches 77 of the two first rotating plates 75, the first rotating plates 75 are in a stable non-rotating state, and the U-shaped surrounding rods 1 are in a horizontally extended and used state. When the first pushing plate 72 is driven to squeeze the first elastic member 71, the first slider 74 squeezes the second elastic member 73, and the first limiting rod 78 movably disengages from the notches 77 of the two first rotating plates 75;

[0049] When it is necessary to fold and store the fence, that is, when the U-shaped surrounding rods 1 are transformed from the horizontally extended and used state to the vertically folded and stored state, by pushing the first pushing plate 72 upward, the first pushing plate 72 squeezes the first elastic member 71. During the upward movement of the first pushing plate 72, it squeezes the first slider 74, and the first slider 74 squeezes the second elastic member 73. The first slider 74 drives the first limiting rod 78 to movably disengage from the two notches 77, so that the first limiting rod 78 no longer limits and fixes the two first rotating plates 75, and thus the two U-shaped surrounding rods 1 can be folded towards each other for storage, transforming from the horizontally extended and used state to the vertically folded and stored state (at this time, both the first elastic member 71 and the second elastic member 73 are in a compressed state, and the first rotating plate 75 abuts against the first limiting rod 78);

[0050] Conversely, when it is necessary to convert the two U-shaped enclosing rods 1 from the vertically folded storage state to the horizontally unfolded use state, only need to rotate the U-shaped enclosing rods 1 to the horizontal state (at this time, the two first rotating plates 75 rotate in the opposite direction). At this time, the two notches 77 are aligned and overlapped, and the second elastic member 73 rebounds to drive the first slider 74 to move, so that the first limiting rod 78 passes through the two notches 77 again, thereby completing the limiting and fixing of the two first rotating plates 75. At the same time, the first elastic member 71 rebounds to drive the first pushing plate 72 to move downward.

[0051] As Figure 1 , Figure 4 and Figure 5 shown, the second locking mechanism 8 includes a second rotating plate 83, a second pushing plate 81, a third elastic member 82, a fixed shaft 85 and a second limiting rod 84. The second pushing plate 81 faces the first support member 5. One side of the second support member 6 is fixedly installed with a fixed shaft 85. Two second rotating plates 83 are rotatably connected concentrically on the fixed shaft 85. The outer wall of the fixed shaft 85 is fixedly installed with a third elastic member 82. One end of the third elastic member 82 is fixedly connected to the second pushing plate 81. A second limiting rod 84 is fixedly installed on the side of the second pushing plate 81 facing the second rotating plate 83. The second rotating plate 83 is fixedly connected to the support rod 31. Each second rotating plate 83 is provided with a second guiding groove 832 and a limiting hole 831 adapted to the cross-sectional size of the second limiting rod 84. When the two limiting holes 831 overlap, the two second guiding grooves 832 are symmetrically arranged along the connection line between the limiting hole 831 and the fixed shaft 85. The limiting hole 831 is communicated with the second guiding groove 832. When the third elastic member 82 is in a compressed state, the second limiting rod 84 is located in the second guiding groove 832. When the third elastic member 82 is in its original length, the second limiting rod 84 is located in the limiting hole 831, and the second rotating plate 83 is in a stable non-rotating state;

[0052] During use, when it is necessary to fold and store the bracket 3, when the two support rods 31 are converted from the use state of being spread out in a V-shape to the vertically folded storage state, by pressing the second pushing plate 81, the second pushing plate 81 compresses the third elastic member 82, and the second pushing plate 81 drives the second limiting rod 84 to move downward, so that the second limiting rod 84 moves from the limiting hole 831 to the second guiding groove 832. Thus, the second limiting rod 84 no longer limits and fixes the two second rotating plates 83, and the two second rotating plates 83 can rotate towards each other, so that the two support rods 31 are converted from the use state of being spread out in a V-shape to the vertically folded storage state, that is, the folding and storage of the bracket 3 is completed (as Figure 14 shown);

[0053] Conversely, when it is necessary to convert the two support rods 31 from the vertically folded storage state to the V-shaped unfolded use state, the two support rods 31 can be opened to form a V-shape. At this time, the two support rods 31 drive the two second rotating plates 83 to rotate in the opposite direction until the second limiting rod 84 moves out of the second guiding groove 832 and enters the limiting hole 831 at the same time, thereby completing the limiting and fixing of the two second rotating plates 83, so that the two support rods 31 can be quickly converted from the vertically folded storage state to the V-shaped unfolded use state (as Figure 1 shown).

[0054] As Figure 1 shown, the chassis 2 (when in use, the periphery of the chassis 2 can also be wrapped with cloth to ensure comfort) includes a connecting plate 21 and side plates 22 symmetrically hinged to both long sides of the connecting plate 21. Both short sides of the connecting plate 21 are fixedly connected with second support members 6;

[0055] By arranging the side plates 22 to be hinged to the connecting plate 21, when the baby crib is in use, the U-shaped guardrail 1 is in the horizontally unfolded use state. At this time, the U-shaped guardrail 1 is connected to the side plates 22 through cloth (the cloth is wrapped around the periphery of the U-shaped guardrail 1), and the U-shaped guardrail 1 supports the side plates 22 through the cloth, so that they are in the horizontal placement state (as Figure 1 shown). Conversely, when the U-shaped guardrail 1 is in the vertically folded storage state, the distance between the U-shaped guardrail 1 and the chassis 2 becomes smaller, so that the side plates 22 will automatically fold, further reducing the occupied space when the baby crib is folded and stored.

[0056] As Figure 1 , Figure 7 , Figure 8 , Figure 9 and Figure 10 shown, the baby crib further includes a third locking mechanism 9. One end of the side tube 4 is fixedly connected with a first support member 5, the other end of the side tube 4 slides through the second support member 6, and the third locking mechanism 9 is used for fixing the position of the side tube 4;

[0057] The third locking mechanism 9 includes a fourth elastic member 91, a fifth elastic member 92, a pressing plate 94, a third connecting member 93, a clamping plate 95, a convex clamping block 96, a fixing rod 97 and an eighth elastic member 98. The fixing rod 97 is fixed inside the side tube 4. The clamping plate 95 has a hollowed-out section. The fixing rod 97 is provided with a first installation groove 971, a second installation groove 972 for accommodating the convex clamping block 96, and a third installation groove 973 for installing the eighth elastic member 98 that are communicated with each other from top to bottom. The top surface of the inner wall of the third installation groove 973 is fixedly installed with the eighth elastic member 98. One end of the eighth elastic member 98 is fixedly connected to the clamping plate 95. When the fourth elastic member 91 is in its original length, the bottom end of the clamping plate 95 contacts the bottom surface of the third installation groove 973, and there is a gap between the top end of the clamping plate 95 and the top surface of the inner wall of the first installation groove 971. One side of the convex clamping block 96 opposite to the protruding end is fixedly installed with the fifth elastic member 92. When the fixing rod 97 is located inside the side tube 4, one end of the fifth elastic member 92 abuts against the inner wall of the side tube 4. The lower side of the side where the convex clamping block 96 and the hollowed-out section of the clamping plate 95 are facing and fitting is set as an inclined surface, and the inclined surface is inclined downward from the protruding end of the convex clamping block 96 to the end opposite to the fifth elastic member 92. When the fifth elastic member 92 is in its original length, the protruding end of the convex clamping block 96 penetrates through the side tube 4. When the clamping plate 95 moves upward, the convex clamping block 96 moves into the second installation groove 972. The clamping plate 95 is movably arranged inside the fixing rod 97. One side of the pressing plate 94 is fixedly installed with a third push plate 941. The third push plate 941 movably penetrates through the first support member 5. Both the third connecting member 93 and the clamping plate 95 are located inside the side tube 4. The top surface of the inner wall of the first support member 5 is fixedly installed with the fourth elastic member 91. One end of the fourth elastic member 91 is fixedly connected to the pressing plate 94. The bottom end of the pressing plate 94 is fixedly installed with the clamping plate 95 through the third connecting member 93. The second support member 6 is provided with a plurality of card slots 61 adapted to the protruding ends of the convex clamping blocks 96 on the side facing the side tube 4 from top to bottom;

[0058] The third connecting member 93 here can be set as a steel wire rope, and the side tube 4 can be an aluminum tube;

[0059] When it is necessary to adjust the heights of the U-shaped surrounding rod 1 and the chassis 2, by pushing the third push plate 941, the third push plate 941 drives the pressing plate 94 to move upward, so that the pressing plate 94 squeezes the fourth elastic member 91. The pressing plate 94 also drives the third connecting member 93 to move upward at the same time. The third connecting member 93 drives the clamping plate 95 to move upward. The clamping plate 95 squeezes the eighth elastic member 98. When the clamping plate 95 moves upward, it drives the convex clamping block 96 to move, so that the convex clamping block 96 squeezes the fifth elastic member 92 until the protruding end of the convex clamping block 96 is movably disengaged from the card slot 61 and enters the second installation groove 972, so that the convex clamping block 96 no longer fixes the position of the side tube 4, facilitating the up and down adjustment of the height position of the side tube 4;

[0060] After the position is adjusted, release the third push plate 941, so that the fourth elastic member 91 and the eighth elastic member 98 rebound to drive the pressing plate 94, the third connecting member 93 and the clamping plate 95 to move downward. At this time, the fifth elastic member 92 rebounds to drive the convex-shaped clamping block 96 to move closer to the second support member 6, so that the protruding end of the convex-shaped clamping block 96 moves out of the second installation groove 972 through the side pipe 4 and enters a clamping groove 61, thereby completing the positioning and fixing of the side pipe 4 again;

[0061] When the positions of the U-shaped railing 1 and the chassis 2 are adjusted to the lowest, at this time, the protruding end of the convex-shaped clamping block 96 is located in the lowermost clamping groove 61, and at this time, the storage and folding volume of the crib is the smallest.

[0062] It should be noted that since the second push plate 81 faces the first support member 5 and the first push plate 72 faces the second support member 6, when the side pipe 4 is adjusted to move downward, the first support member 5 gradually moves closer to the second support member 6 until the second support member 6 presses on the first push plate 72 and the first support member 5 presses on the second push plate 81, avoiding the trouble of manually pressing the first push plate 72 and the second push plate 81 respectively, and realizing the one-key folding and storage function of the crib (only need to press the third push plate 941 to adjust the side pipe 4 to slide downward along the second support member 6, so that the first support member 5 and the railing move downward).

[0063] As Figure 1 、 Figure 6 、 Figure 11 、 Figure 12 and Figure 13 As shown in

[0064] Specifically, grooves are provided at both ends of the straight rod 102. Screws are symmetrically and fixedly inserted on the outer surface of the straight rod 102 at both ends. The screws are located in the grooves. A sixth elastic member 11 is fixedly installed on the screws. One end of the sixth elastic member 11 is fixedly installed with an insertion rod 12. One side of the outer wall of the insertion rod 12 is fixedly installed with a second slider 13 through a connecting block 121 (a sliding groove for the connecting block 121 to slide is provided on the outer surface of the straight rod 102). The second slider 13 slides on the outer surface of the straight rod 102. First connecting members 10 are fixedly installed at both ends of the straight rod 102. When the sixth elastic member 11 is in its original length, the insertion rod 12 movably passes through the first connecting member 10. The bending rod 101 is fixedly installed with a second connecting member 14. A slot 141 adapted to the insertion rod 12 is provided at one end of the second connecting member 14 facing the straight rod 102. The first connecting member 10 and the second connecting member 14 are buckled (which is an existing buckling member, facilitating the quick splicing of the straight rod 102 and the bending rod 101. When the first connecting member 10 and the second connecting member 14 are buckled, the insertion rod 12 faces the slot 141);

[0065] When it is necessary to disassemble the straight rod 102 so that the crib fits seamlessly with a regular bed, push the two second sliders 13, which will drive the connecting block 121 to move. The connecting block 121 will drive the insertion rod 12 to move, causing the insertion rod 12 to squeeze the sixth elastic member 11. As a result, the insertion rod 12 will move out of the insertion slot 141, and the quick disassembly of the straight rod 102 can be completed.

[0066] Conversely, when it is necessary to install the straight rod 102, first push the two second sliders 13 to drive the insertion rod 12 to move and squeeze the sixth elastic member 11, so that the insertion rod 12 completely enters the groove, ensuring that the insertion rod 12 will not obstruct when the first connecting member 10 and the second connecting member 14 are latched. After the first connecting member 10 and the second connecting member 14 are latched, release the second slider 13, and the sixth elastic member 11 will rebound, driving one end of the insertion rod 12 to move out of the groove and into the insertion slot 141, thus completing the fixation of the straight rod 102.

[0067] As Figure 1 、 Figure 9 and Figure 14 shown, a bottom groove is provided at the bottom of the first support member 5. A third push plate 941 is movably arranged in the bottom groove. A side groove is provided on one side of the outer wall of the third push plate 941. A seventh elastic member 15 is fixedly installed on one side of the inner wall of the side groove. One end of the seventh elastic member 15 is fixedly installed with a limit block 16. When the seventh elastic member 15 is in its original length, the limit block 16 movably protrudes from the side groove, and the limit block 16 contacts the first support member 5.

[0068] By providing the seventh elastic member 15 and the limit block 16, when it is necessary to press the third push plate 941 to drive the pressing plate 94 to move and squeeze the fourth elastic member 91, thus facilitating the adjustment of the height position of the fence (the specific adjustment principle has been described above), it is necessary to first press the limit block 16 to drive the seventh elastic member 15 to be squeezed until the limit block 16 moves into the side groove, so that the limit block 16 no longer obstructs the pressing of the third push plate 941, achieving the function of being able to press the third push plate 941. Conversely, when the fence is adjusted to the required height, stop pressing the third push plate 941. The fourth elastic member 91 rebounds and returns to its original length, driving the pressing plate 94 to move downward, thereby driving a part of the third push plate 941 to move out of the bottom groove. As a result, the limit block 16 is no longer abutted by the inner wall of the side groove, and the limit block 16 moves out of the bottom groove. At this time, the seventh elastic member 15 rebounds, driving the limit block 16 to move until the limit block 16 fits and contacts the bottom of the first support member 5, thus preventing people from accidentally pressing the third push plate 941. It is necessary to press the limit block 16 before pressing the third push plate 941.

[0069] The first elastic member 71, the second elastic member 73, the third elastic member 82, the fourth elastic member 91, the fifth elastic member 92, the sixth elastic member 11, and the seventh elastic member 15 here can all be springs.

[0070] AsFigure 1 and Figure 15 As shown in Figure 15 , several parallel reinforcing bars 17 are fixedly installed between two groups of brackets 3. At the bottom end of each support rod 31, a universal wheel 18 with a brake pad and a leg 19 are fixedly installed. When the support rod 31 is in the use state of being unfolded in a V shape, the leg 19 contacts the ground and the universal wheel 18 is suspended. When the support rod 31 is in the vertically folded and stored state, the universal wheel 18 contacts the ground and the leg 19 is suspended, facilitating the movement of the crib.

[0071] By providing the reinforcing bars 17, the stability and strength of the crib during use are enhanced. By providing the universal wheels 18 with brake pads, the movement or fixation of the crib can be conveniently controlled. By providing the legs 19, the entire crib can be placed more stably when the crib is folded and stored.

[0072] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
