[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions in the embodiments of this invention will be clearly and completely described below in conjunction with the embodiments of this invention. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. The components of the embodiments of this invention can be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of the claimed technical solutions of the invention.

[0030] Example:

[0031] like Figures 1 to 3 As shown, this embodiment provides a crib, including:

[0032] The bed body has an open-top cavity.

[0033] Fixed rail 1 is installed on the bed body;

[0034] The movable railing 2 has an opening at the side end of the fixed railing 1. The movable railing 2 is movably set at the opening, and the left and right ends of the movable railing 2 are respectively connected to the fixed railing 1.

[0035] Shrinkable component 3 is located at the open position and is connected to both sides of the movable bar 2 respectively;

[0036] Side curtain 4 is mounted on retractable assembly 3, and its upper end is connected to movable rail 2. Under external force, movable rail 2 moves down or up through the coordinated action of movable rail 2 and retractable assembly 3. The movement of movable rail 2 drives side curtain 4 to fold or unfold synchronously.

[0037] In this embodiment, a receiving cavity with an open upper end is defined within the bed body. A fixed railing 1 is provided on the bed body, and an opening is provided on at least one side of the bed body. A movable railing 2 is vertically and vertically positioned at the opening. The movable railing 2 and the fixed railing 1 are connected to each other to form a railing. A retractable assembly 3 is provided at the opening, and a side curtain 4 is provided on the retractable assembly 3. The upper end of the side curtain 4 is connected to the movable railing 2 so that the movable railing 2 drives the side curtain 4 to move up and down synchronously. Under the action of external force, the movable railing 2 and the retractable assembly 3 work together to cause the movable railing 2 to move down or up in the vertical direction. The movement of the movable railing 2 drives the bed body to move up and down. The movable side curtain 4 folds or unfolds synchronously, causing the height of the movable rail 2 to switch between the upper and lower ends of the opening. This allows the side curtain 4 to open or close the opening. Specifically, when the movable rail 2 rises to the upper end of the opening, it connects with the fixed rail 1, making the top wall of the movable rail 2 the same height as the top wall of the fixed rail 1, thus closing the opening. Alternatively, when the movable rail 2 disconnects from the fixed rail 1, it descends to the lower end of the opening, thus opening the opening. Its simple structure allows for reasonable adjustment of the crib rail height according to actual needs, thereby further improving the user experience.

[0038] Furthermore, the retractable assembly 3 includes a horizontal bar 31, a first connecting rope 32, and a second connecting rope 33.

[0040] Specifically, the retractable assembly 3 also includes a first fixing seat 35. One end of the first fixing seat 35 is detachably connected to the left or right end of the movable rail 2. The first fixing seat 35 has a first connecting cavity with an open side on the side away from the movable rail 2. At least part of the fixing rail 1 extends into the first connecting cavity so that the fixing rail 1 is installed together with the first fixing seat 35. A first protruding rod 351 is provided at the lower end of the first fixing seat 35. The upper end of the first vertical rod 5 or the second vertical rod 6 is sleeved on the outside of the first protruding rod 351.

[0041] The second fixing seat 36 has a second connecting cavity with an open side on one side. At least a portion of the left or right end of the crossbar 31 extends into the second connecting cavity so that the crossbar 31 is installed together with the second fixing seat 36. A second protruding rod 361 is provided at the upper end of the second fixing seat 36. The lower end of the first vertical rod 5 or the second vertical rod 6 is sleeved on the outside of the second protruding rod 361.

[0042] Furthermore, the retractable assembly 3 also includes a first connecting seat 37 and a second connecting seat 38, wherein the first connecting seat 37 and the second connecting seat 38 are respectively disposed on the left and right ends of the movable rail 2. The first vertical rod 5 has a first sliding cavity 51 with open upper and lower ends at one end near the side curtain 4, and the first connecting seat 37 is slidably disposed in the first sliding cavity 51. The second vertical rod 6 has a second sliding cavity with open upper and lower ends at one end near the side curtain 4, and the second connecting seat 38 is slidably disposed in the second sliding cavity. The first sliding cavity 51 and the second sliding cavity... Slide grooves 39 are provided on the side wall near one end of the side curtain 4. The two ends of the side curtain 4 are respectively inserted into the slide grooves 39. One end of the first connecting rope 32 is connected to the lower end of the first connecting seat 37, and the other end passes through the first mounting hole 41, the internal space of the horizontal bar 31, and the internal space of the second vertical bar 6 in sequence before being connected to the upper end of the second connecting seat 38. One end of the second connecting rope 33 is connected to the upper end of the first connecting seat 37, and the other end passes through the internal space of the first vertical bar 5, the internal space of the horizontal bar 31, and the second mounting hole 42 in sequence before being connected to the lower end of the second connecting seat 38.

[0043] Preferably, it also includes a first limiting rod and a second limiting rod, wherein a first limiting cavity 21 with an open lower end is defined at the lower end of the movable rail 2, and the first limiting rod is locked in the first limiting cavity 21; a second limiting cavity 311 with an open upper end is recessed at the upper end of the crossbar 31, and the second limiting rod is locked in the second limiting cavity 311; the upper end of the side curtain 4 passes through the bottom wall of the first limiting cavity 21 and is connected to the first limiting rod, and its lower end passes through the top wall of the second cavity and is connected to the second limiting rod.

[0044] In this embodiment, the fixed railing 1 is connected to a first fixed seat 35 at each of its open ends. At least a portion of the fixed railing 1 extends into the first connecting cavity of the first fixed seat 35 to install the fixed railing 1 and the first fixed seat 35 together. This allows the movable railing 2 to establish or disconnect a connection with the fixed railing 1 through the first fixed seat 35. A first protruding rod 351 protrudes downward from the lower end of the first fixed seat 35. Cavities with open upper and lower ends are defined in the first vertical rod 5 and the second vertical rod 6, respectively. The upper end of the cavity of the first vertical rod 5 or the second vertical rod 6 is fitted onto the outside of the first protruding rod 351, thereby connecting the fixed railing 1, the first vertical rod 5, and the movable railing 2 together. Similarly... Furthermore, the fixed railing 1, the second vertical bar 6, and the movable railing 2 can be connected together. At least a portion of the left or right end of the horizontal bar 31 extends into the second connecting cavity of the second fixed seat 36 so that the horizontal bar 31 and the second fixed seat 36 are installed together. A second protruding rod 361 is provided at the upper end of the second fixed seat 36. The lower end of the cavity of the first vertical bar 5 or the second vertical bar 6 is sleeved on the outside of the second protruding rod 361, so that the first vertical bar 5 and the horizontal bar 31 can be connected together. Similarly, the second vertical bar 6 and the horizontal bar 31 can also be connected together, so that the cavity of the first vertical bar 5, the internal space of the horizontal bar 31, and the cavity of the second vertical bar 6 are interconnected. Furthermore, a first roller 331 is provided at the upper end of the first vertical rod 5, that is, the first roller 331 is rotatably mounted in the first fixed seat 35 on the left side of the movable rail 2; a second roller 332 is provided at the lower end of the first vertical rod 5, that is, the second roller 332 is rotatably mounted in the second fixed seat 36 on the left side of the horizontal rod 31; a third roller 321 is provided at the lower end of the second vertical rod 6, that is, the third roller 321 is rotatably mounted in the second fixed seat 36 on the right side of the horizontal rod 31; and a fourth roller 322 is provided at the upper end of the second vertical rod 6, that is, the fourth roller 322 is rotatably mounted in the first fixed seat 35 on the right side of the movable rail 2. One end of the first connecting rope 32 is connected to the movable rail 2. The lower left end of the movable rail 2 is connected to the other end, which passes through the cavity of the first vertical bar 5, through the internal space of the horizontal bar 31, around the third roller 321, through the cavity of the second vertical bar 6, and around the fourth roller 322 before connecting to the upper right end of the movable rail 2. At the same time, one end of the second connecting rope 33 is connected to the upper left end of the movable rail 2, and the other end passes through the first roller 331, through the cavity of the first vertical bar 5, around the second roller 332, through the internal space of the horizontal bar 31, through the cavity of the second vertical bar 6, and then connects to the lower right end of the movable rail 2. In this way, the lifting and lowering movement of the movable rail 2 can be made more stable through the coordinated action of the first connecting rope 32 and the second connecting rope 33.

[0045] More preferably, to avoid knotting of the first connecting rope 32 and the second connecting rope 33, the cavity inside the first vertical rod 5 can be independently set from the first sliding cavity 51, and the cavity inside the second vertical rod 6 can be independently set from the second sliding cavity. The two ends of the side curtain 4 are respectively inserted into the sliding groove 39, so that the first mounting hole 41 of the side curtain 4 is located in the first sliding cavity 51, and the second mounting hole 42 of the side curtain 4 is located in the second sliding cavity. One end of the first connecting rope 32 is connected to the lower end of the first connecting seat 37, and the other end... The first end of the second connecting rope 33 passes through the first sliding cavity 51, the interior space of the crossbar 31, wraps around the third roller 321, passes through the cavity of the second vertical rod 6, wraps around the fourth roller 322, and then connects to the upper end of the second connecting seat 38. One end of the second connecting rope 33 is connected to the upper end of the first connecting seat 37, and the other end is wrapped around the first roller 331, passes through the cavity of the first vertical rod 5, wraps around the second roller 332, passes through the interior space of the crossbar 31, passes through the second sliding cavity, and then connects to the lower end of the second connecting seat 38. In addition, the left side of the side curtain 4 passes through the groove 39 of the first sliding cavity 51 so that the first mounting hole 41 and the first connecting rope 32 are connected at the end near the first connecting seat 37. The right side of the side curtain 4 passes through the groove 39 of the second sliding cavity so that the second mounting hole 42 and the second connecting rope 33 are connected at the end near the second connecting seat 38, thereby completing the assembly of the left and right sides of the side curtain 4. Secondly, since the side curtain 4 is a double-layered curtain, a first limiting rod and a second limiting rod are respectively set at the inner positions of the upper and lower ends of the side curtain 4. By locking the first limiting rod and the second limiting rod into the corresponding limiting cavities, the upper end of the side curtain 4 passes through the open end of the first limiting cavity 21 and connects with the first limiting rod, and its lower end passes through the open end of the second cavity and connects with the second limiting rod. This completes the assembly of the upper and lower ends of the side curtain 4. This facilitates the assembly and fixation of the side curtain 4 and makes the assembly of the side curtain 4 more reliable. As a result, the side curtain 4 can fold or unfold synchronously with the lifting and lowering movement of the movable railing 2.

[0046] Furthermore, it also includes a locking component 7, which is disposed on the movable bar 2. The action of the locking component 7 can establish or disconnect the connection between the movable bar 2 and the fixed bar 1.

[0047] Preferably, the locking assembly 7 includes a button 71, a locking member 72, a connecting strap 73, and a spring 74. A mounting base 22 is provided on the outer wall of the movable rail 2, and a mounting cavity is defined within the mounting base 22. A button 71 is provided on each of the left and right ends of the mounting cavity. A cavity is defined on each of the left and right ends of the fixed rail 1. A locking member 72 is provided in each cavity. Each button 71 is connected to the corresponding locking member 72 through the connecting strap 73. A through hole is provided on the end wall of the cavity near the fixed rail 1. A locking hole 11 that mates with the through hole is provided on the side wall of the fixed rail 1. A locking rod 721 protrudes from the locking member 72. The locking rod 721 is adapted to establish or disconnect the connection with the locking hole 11 after passing through the through hole. One end of the spring 74 abuts against the end of the locking member 72 away from the locking rod 721, and the other end abuts against the side wall of the cavity to perform a reset movement of the locking member 72.

[0048] Specifically, a limiting plate 23 is provided at the middle position of the mounting base 22. The front side wall of the button 71, which is away from the connecting strip 73, abuts against the rear wall of the limiting plate 23. A protruding plate 711 is provided on the front side wall of the button 71. The protruding plate 711 is correspondingly provided with the side wall of the limiting plate 23 so that the limiting plate 23 limits the lateral displacement of the protruding plate 711.

[0049] The button 71 has a first locking cavity at one end near the connecting band 73, and the locking member 72 has a second locking cavity at one end away from the locking rod 721. A first locking member and a second locking member are respectively provided at both ends of the connecting band 73. The first locking member is locked in the first locking cavity, and the second locking member is locked in the second locking cavity. One end of the connecting band 73 passes through the side wall of the first locking cavity and is connected to the first locking member. The other end passes through the side wall of the second locking cavity and the spring 74 in sequence and is connected to the second locking member.

[0050] In this embodiment, to securely connect the movable rod and the fixed rod, a mounting base 22 is provided at the middle position of the front end of the movable rail 2. A mounting cavity is defined within the mounting base 22, and a limiting plate 23 is provided at the middle position of the mounting base 22. A button 71 is provided at each of the left and right ends of the mounting cavity. The front sidewalls of the two buttons 71 abut against the rear wall of the limiting plate 23 to limit the forward movement of the buttons 71. Cavities are defined at the left and right ends of the fixed rail 1, and a locking element 72 is provided in each cavity. Each button 71 is connected to the corresponding locking element 72 at the end away from the limiting plate 23 via a connecting strap 73. A through hole is provided on the end wall of the cavity near the fixed rail 1. A locking hole 11 is provided on the side wall of the locking member 72 to cooperate with the through hole. A locking rod 721 is protruding on the side wall of the locking member 72 away from the end of the connecting band 73. Under the action of external force, the two buttons 71 move from both sides of the mounting base 22 toward the middle position so that the protrusion 711 of the button 71 abuts against the limiting plate 23. The button 71 drives the locking member 72 to move synchronously from both sides of the mounting base 22 toward the middle position through the connecting band 73, thereby disconnecting the locking rod 721 from the locking hole 11. Alternatively, when the user releases the button 71, under the action of the spring 74, the locking member 72 and the button 71 move synchronously to reset, thereby allowing the locking rod 721 to pass through the through hole and establish a connection with the locking hole 11, thus locking the movable rail 2 and the fixed rail 1 together securely.

[0051] In this embodiment, if the height of the movable rail 2 needs to be lowered, firstly, the two buttons 71 are driven by external force to move from both sides of the mounting base 22 towards the middle position, so that the protrusions 711 of the buttons 71 abut against the limiting plate 23. The buttons 71 drive the locking member 72 to move synchronously from both sides of the mounting base 22 towards the middle position through the connecting belt 73, thereby disconnecting the locking hole 11 of the locking rod 721, and thus disconnecting the connection between the movable rail 2 and the fixed rail 1. Next, the movable rail 2 is driven by external force to move downward. Then, the movement of the movable rail 2 drives the side curtain 4 to fold synchronously until the movable rail 2 descends to the upper position of the crossbar 31, that is, the movable rail 2 descends. The opening is opened by the cooperation of the movable rail 2 and the side curtain 4 at the lower end of the opening. If the height of the movable rail 2 needs to be adjusted, firstly, the movable rail 2 is driven upward by external force. The upward movement of the movable rail 2 drives the side curtain 4 to unfold synchronously until the movable rail 2 rises to the position of the fixed rod, that is, the upper end of the opening. Then, under the elastic force of the spring 74, the locking part 72 and the button 71 move back to their original positions, so that the locking rod 721 passes through the through hole and establishes a connection with the locking hole 11, thereby locking the movable rail 2 and the fixed rail 1 together.
