A surround rod assembly and a child's bed

Abstract

The application discloses a rail assembly and a child bed. The rail assembly comprises a first rod group and a stabilizing structure. The first rod group comprises two first rails. The stabilizing structure comprises a stabilizing column and two stabilizing rods. The stabilizing column is arranged on a first connecting piece. The two stabilizing rods correspond to the two first rails respectively. One end of each stabilizing rod is hingedly connected to a first rail. The other end of each stabilizing rod is slidably connected to the stabilizing column. The first rails and the stabilizing column are connected together through the stabilizing rods. The stabilizing rods can limit the angle between the first rails and the vertical direction. The angle between the first rails and the first connecting piece changes gradually during the folding process. When the positions of the supporting pieces on both sides of the first rod group remain unchanged, the angle between the first rails and the first connecting piece is temporarily fixed. The first connecting piece will not swing horizontally. At any moment during the folding process of the child bed, the relative position between the first rails and the first connecting piece is stable, which is beneficial to the smooth folding of the child bed.

Description

Technical Field

[0001] This application relates to the field of children's products technology, and in particular to a railing assembly and a children's bed. Background Technology

[0002] A children's bed provides a space for children to sleep or play. Children's beds can be folded for storage to enhance convenience. Existing children's beds include support legs and side rails mounted on the legs. The side rails have a high degree of freedom, resulting in poor stability when switching between different bed configurations, increasing the difficulty of this process.

[0003] Therefore, improvements to existing technologies are necessary. Utility Model Content

[0004] This application aims to solve at least one of the technical problems existing in the prior art by providing a fence assembly and a children's bed.

[0005] According to one aspect of this application, a railing assembly is provided for use in a children's bed, the children's bed including a support member; the railing assembly includes a first rod group and a stabilizing structure; the first rod group includes a first connector and two first rails, the two first rails being respectively hinged to opposite sides of the first connector, and the end of the first rail away from the first connector being hinged to the support member; the stabilizing structure includes a stabilizing column and two stabilizing rods, the stabilizing column being disposed on the first connector, the two stabilizing rods corresponding to the two first rails respectively, and one end of the stabilizing rod being hinged to the first rail, the other end of the stabilizing rod being slidably connected to the stabilizing column.

[0006] In one embodiment, the stabilizing column is provided with a connecting groove that extends vertically; the ends of the two stabilizing rods near the stabilizing column are slidably connected to the connecting groove by a sliding pin, the hinge point of one of the stabilizing rods and one of the first surrounding rods is denoted as point A1, and the hinge point of the other stabilizing rod and the other first surrounding rod is denoted as point A2; when the children's bed is in the unfolded state, the distance between point A1 and the sliding pin is equal to the distance between point A2 and the sliding pin.

[0007] In one embodiment, a second rod assembly is further included. The second rod assembly includes a second connector and two second retaining rods. The two second retaining rods are respectively hinged to opposite sides of the second connector, and the end of the second retaining rod away from the second connector is hinged to the support member. The hinge point between the second retaining rod and the support member is located below the hinge point between the first retaining rod and the support member. The second rod assembly is provided with the stabilizing structure. In the stabilizing structure provided by the second rod assembly, the stabilizing column is disposed on the second connector, one end of the stabilizing rod is hinged to the second retaining rod, and the other end of the stabilizing rod is slidably connected to the stabilizing column.

[0008] In one embodiment, in the stabilizing structure of the first rod group, the stabilizing post extends toward the second connector; in the stabilizing structure of the second rod group, the stabilizing post extends toward the first connector; and the two stabilizing posts are integrally formed.

[0009] In one embodiment, both the first and second rod groups are provided with a locking structure; the children's bed has an unfolded form and a folded form; when the children's bed is in the unfolded form, the locking structure is configured to restrict the relative position between the two first rods and the two second rods; during the process of the children's bed switching from the unfolded form to the folded form, the hinge points of the two first rods and the hinge points of the two second rods move toward the bottom of the children's bed.

[0010] In one embodiment, when the children's bed is in the unfolded state, the first railing and the second railing extend along a first direction. The hinge point between the first railing and the support member is denoted as point B, and the hinge point between the second railing and the support member is denoted as point C. In the first direction, point C is located on the side of point B away from the two hinge points of the first railing.

[0011] In one embodiment, two sets of the second rod group are spaced apart along the second direction; when the children's bed is in the unfolded state, the second rail extends along the first direction, and in the two sets of the second rod group, the distance from the hinge point of each second rail to the bottom of the support member is the same, and the second direction is perpendicular to the first direction.

[0012] In one embodiment, the locking structure includes a spring pin, a locking rod, and a driving block. The spring pin is inserted into the end of the first enclosure rod near the first connector via the locking rod. The end of the first enclosure rod near the first connector has a mounting groove, and the locking rod slides into the mounting groove. The first connector has a fixing groove and a guide groove that are connected to each other. The driving block is configured to drive the spring pin to move axially along the first enclosure rod and drive the locking rod to slide from the fixing groove to the guide groove to release the locking state of the first enclosure rod.

[0013] In one embodiment, a linkage structure is connected between the first linkage group and the second linkage group for motion coordination between the first linkage group and the second linkage group.

[0014] According to another aspect of this application, a children's bed is provided, including any of the aforementioned railing assemblies.

[0015] The beneficial effects of this application are as follows: By connecting the first frame rod and the stabilizing column together with the stabilizing rod, during the folding process of the first frame rod group, the stabilizing rod can limit the angle between the first frame rod and the vertical direction (i.e., limit the angle between the first frame rod and the first connecting member). The angle between the first frame rod and the first connecting member changes gradually with the folding process. When the positions of the support members on both sides of the first frame rod group remain unchanged, the angle between the first frame rod and the first connecting member is temporarily fixed, and the first connecting member will not swing laterally. That is, at any moment during the folding process of the children's bed, the relative position between the first frame rod and the first connecting member is stable, which is conducive to the smooth folding of the children's bed.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0033] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0034] The fence assembly and children's bed of this application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Existing children's beds include support legs and railings mounted on the support legs. The railings have a high degree of freedom, which makes the children's bed unstable when switching between different states, increasing the difficulty of switching the children's bed to different states.

[0036] To address the aforementioned technical problems, this application provides a railing assembly for use in a children's bed. The children's bed includes a support member. The railing assembly includes a first rod group and a stabilizing structure. The first rod group includes a first connector and two first rails, each of which is hinged to opposite sides of the first connector, with one end of each first rail away from the first connector hinged to the support member. The stabilizing structure includes a stabilizing column and two stabilizing rods. The stabilizing column is disposed on the first connector, and the two stabilizing rods correspond to the two first rails, with one end of each stabilizing rod hinged to a first rail and the other end slidably connected to the stabilizing column. This will be described in detail below.

[0037] See Figure 1 , Figure 3 as well as Figure 4 The railing assembly is used in a children's bed, which includes a support member 10. The railing assembly includes a first rod group 20 and a stabilizing structure 60. The first rod group 20 includes a first connector 22 and two first rails 21. The two first rails 21 are respectively hinged to opposite sides of the first connector 22, and the end of the first rail 21 away from the first connector 22 is hinged to the support member 10. The stabilizing structure 60 includes a stabilizing column 61 and two stabilizing rods 62. The stabilizing column 61 is disposed on the first connector 22, and the two stabilizing rods 62 are respectively corresponding to the two first rails 21. One end of the stabilizing rod 62 is hinged to the first rail 21, and the other end of the stabilizing rod 62 is slidably connected to the stabilizing column 61.

[0038] Since one end of the first support rod 21 is hinged to the first connector 22 and the other end is hinged to the support member 10, the two ends of the first support rod 21 have a high degree of freedom. When the children's bed is unfolded or folded, the first rod group 20 is prone to swaying (i.e., in the view shown in the figure, the first connector 22 is prone to swaying laterally), which is not conducive to the smooth switching of the children's bed state. In this embodiment, by setting the stabilizing structure 60, the stability of the children's bed during the unfolding or folding process can be guaranteed, and the efficiency of the children's bed state switching can be improved.

[0039] Specifically, the first retaining rod 21 is connected to the stabilizing column 61 by the stabilizing rod 62. During the folding of the first rod group 20, the stabilizing rod 62 can limit the angle between the first retaining rod 21 and the vertical direction (i.e., limit the angle between the first retaining rod 21 and the first connecting member 22). The angle between the first retaining rod 21 and the first connecting member 22 changes gradually with the folding process. When the positions of the support members 10 on both sides of the first rod group 20 remain unchanged, the angle between the first retaining rod 21 and the first connecting member 22 is temporarily fixed, and the first connecting member 22 will not swing laterally. That is, at any moment during the folding process of the children's bed, the relative position between the first retaining rod 21 and the first connecting member 22 is stable, which is conducive to the smooth folding of the children's bed.

[0040] Similarly, during the unfolding process of the children's bed (when the first rod group 20 switches from the folded state to the unfolded state), the stabilizing rod 62 can also limit the angle between the first surrounding rod 21 and the first connecting member 22, which will not be elaborated here.

[0041] The specific folding and closing operation of the children's bed is as follows: the two side support members 10 of the first rod group 20 move closer to the middle, and the first rails 21 on both sides of the first connector 22 rotate around the first connector 22 and move closer. During the rotation of the first rails 21, the end of the stabilizing rod 62 away from the first rails 21 slides, realizing the switching of the angle between the first rails 21 and the first connector 22, until the two support members 10 are close to each other to complete the folding and closing operation of the children's bed.

[0042] It should be noted that the two stabilizer bars 62 correspond to the two first retaining bars 21 respectively. That is, one stabilizer bar 62 is hinged to one of the first retaining bars 21, and the other stabilizer bar 62 is hinged to the other first retaining bar 21. The two first retaining bars 21 are connected by a stabilizer bar 62, which is beneficial to the stability of both sides of the first connecting member 22.

[0043] In some embodiments, the stabilizing column 61 and the first connecting member 22 can be integrally formed, which reduces the number of parts, facilitates processing and forming, and reduces production costs. In some embodiments, the first supporting rod 21 is slidably connected to the first connecting member 22 (the stabilizing column 61 is part of the first connecting member 22). The design is based on the specific shape of the stabilizing rod 62, etc., and is not limited to this. As long as the end of the stabilizing rod 62 away from the first supporting rod 21 can move relative to the first connecting member 22, all of these fall within the protection scope of this application.

[0044] See Figure 4The stabilizing column 61 is provided with a connecting groove 611, which extends vertically. The ends of the two stabilizing rods 62 near the stabilizing column 61 are slidably connected to the connecting groove 611 by a sliding pin 63. The hinge point between one stabilizing rod 62 and one of the first surrounding rods 21 is denoted as point A1, and the hinge point between the other stabilizing rod 62 and the other first surrounding rod 21 is denoted as point A2. When the children's bed is in the unfolded state, the distance between point A1 and the sliding pin 63 is equal to the distance between point A2 and the sliding pin 63.

[0045] In this embodiment, the distance between point A1 and sliding pin 63 is equal to the distance between point A2 and sliding pin 63, and the connecting groove 611 extends vertically, ensuring that the angles between the two first support rods 21 and the vertical direction are equal. During the state switching process of the children's bed, the first rod group 20 always maintains a symmetrical arrangement, so that the support members 10 on both sides always maintain a symmetrical arrangement, which is conducive to improving the stability of the children's bed during the state switching process. The first support rods 21 on both sides of the first connector 22 are symmetrically arranged, so the children's bed will not tilt to one side or the other side, and the center of gravity is well maintained, which is conducive to the smooth transition of the children's bed state.

[0046] Of course, in some embodiments, the distance between point A1 and sliding pin 63 is not equal to the distance between point A2 and sliding pin 63. Compared with this embodiment, the stability is weaker, but it still falls within the protection scope of this application, and will not be elaborated here.

[0047] It is worth mentioning that in this embodiment, the movement of the end of the stabilizer 62 away from the first surrounding rod 21 relative to the first connecting member 22 is achieved by the cooperation of the sliding pin 63 and the connecting groove 611. In some embodiments, the stabilizer 62 can also be guided by a collar sleeved around the stabilizer 61. However, it is not limited to this and can also be arranged in other structural forms.

[0048] See Figure 1-4 The enclosure rod assembly also includes a second rod group 30, which includes a second connector 33 and two second enclosure rods 31. The two second enclosure rods 31 are respectively hinged to opposite sides of the second connector 33, and the end of the second enclosure rod 31 away from the second connector 33 is hinged to the support member 10. The hinge point between the second enclosure rod 31 and the support member 10 is located below the hinge point between the first enclosure rod 21 and the support member 10. The second rod group 30 is provided with a stabilizing structure 60. In the stabilizing structure 60 provided by the second rod group 30, the stabilizing column 61 is provided on the second connector 33, one end of the stabilizing rod 62 is hinged to the second enclosure rod 31, and the other end of the stabilizing rod 62 is slidably connected to the stabilizing column 61.

[0049] For ease of understanding, the hinge point between the first retaining rod 21 and the support member 10 is denoted as point B, and the hinge point between the second retaining rod 31 and the support member 10 is denoted as point C. Figure 1 As shown.

[0050] In this embodiment, the hinge point (point C) between the second support rod 31 and the support member 10 is located below the hinge point (point B) between the first support rod 21 and the support member 10. That is, when the children's bed is in the unfolded state, the second support rod 31 is located below the first support rod 21. With this arrangement, multiple sets of rods (including the first rod set 20 and the second rod set 30) connect multiple points in the vertical direction of the support member 10, which helps to improve the overall stability of the children's bed.

[0051] Meanwhile, the second rod group 30 is also equipped with a stabilizing structure 60, which can ensure the stability during the switching of the child bed state. It is similar to the stabilizing structure 60 set on the first rod group 20 mentioned above. For details, please refer to the aforementioned embodiment, which will not be repeated here.

[0052] See Figure 5 The stabilizing column 61 is set in the stabilizing structure 60 of the first rod group 20, and extends toward the second connector 33. The stabilizing column 61 is set in the stabilizing structure 60 of the second rod group 30, and extends toward the first connector 22. The two stabilizing columns 61 are integrally set.

[0053] by Figure 5 Taking the perspective of the first rod group 20 as an example, the stabilizing rod 62a in the first rod group 20 extends downward, and the stabilizing rod 62b in the second rod group 30 extends upward. In this embodiment, the stabilizing rod 62a and the stabilizing rod 62b are integrally set, that is, the stabilizing rod 62a and the stabilizing rod 62b are the same rod. The first rod group 20 and the second rod group 30 are linked through the same rod. When the first rod group 20 is folded or unfolded, it can drive the second rod group 30 to perform corresponding operations, which can prevent the support member 10 from tilting, improve the stability of the movement of the support member 10 during the folding process of the children's bed, facilitate the smooth switching of the children's bed state, and improve the efficiency of the children's bed state switching.

[0054] In some embodiments, both the first rod group 20 and the second rod group 30 are provided with a locking structure 40; the children's bed has an unfolded form and a folded form. When the children's bed is in the unfolded form, the locking structure 40 is configured to restrict the relative position between the two first side rods 21 and the two second side rods 31; during the process of the children's bed switching from the unfolded form to the folded form, the hinge points of the two first side rods 21 and the hinge points of the two second side rods 31 move toward the bottom of the children's bed.

[0055] During the transition of the children's bed from its unfolded to its folded state, the hinge points between the two first support rods 21 (i.e., the first connecting member 22) and between the two second support rods 31 (i.e., the second connecting member 33) both move toward the bottom of the children's bed. That is, during the folding operation of the children's bed, the ends of the first support rods 21 and the second support rods 31 that are away from the support member 10 move downward.

[0056] By moving the hinge points of the two first rods 21 and the two second rods 31 downwards, the folding and collapsing operations of the first rod group 20 and the second rod group 30 are achieved. Both (the first rod group 20 and the second rod group 30) are folded downwards. After folding, the first rod group 20 and the second rod group 30 are located within the space enclosed by the support member 10, without occupying the space outside the support member 10. This allows the children's bed to be folded up as much as possible. The overall volume of the children's bed after folding is small and does not take up much storage space. At the same time, the folding direction of both is the same, which avoids interference between the first rod group 20 and the second rod group 30 when the children's bed is folded up, which is conducive to the smooth operation of the folding operation and improves the folding efficiency of the children's bed. In addition, after the first rod group 20 and the second rod group 30 are unlocked (i.e., the locking structure 40 is released), the first rod group 20 and the second rod group 30 will move downwards and fold under the action of gravity, reducing the labor intensity during the folding operation.

[0057] The specific folding operation is as follows: Unlock the locking structure 40, putting the first rod group 20 and the second rod group 30 in an active state. Apply an initial force to the first rod group 20 and the second rod group 30, causing the middle of the first rod group 20 and the middle of the second rod group 30 to move downwards, making the two first support rods 21 form a V-shape (the second support rod 31 is similar; this discussion focuses on the first support rod 21, and the second support rod will not be elaborated upon). Then, hold the support member 10 with both hands and move it towards the center. Under the action of gravity and the force generated when the support member 10 moves towards the center (which facilitates smooth folding), the first support rods 21 continue to fold, finally completing the folding operation of the children's bed. During the folding process, after the locking structure 40 is unlocked, both hands only need to act on the support member 10 to complete the folding operation while stabilizing the support member 10, preventing the children's bed from tipping over during folding.

[0058] The following is a brief description of existing children's beds to facilitate understanding of the beneficial technical effects of this application: In the prior art, children's beds often have a base structure at the bottom of the support member 10 to achieve stability. However, the base structure is complex and increases production costs. In this application, the first rod group 20 and the second rod group 30 are essentially the same component, only differing in their installation positions (here, the first rod 21 and the second rod 31 have the same length, although in some embodiments, their lengths may differ). In actual production, this facilitates mass production and reduces production costs. The first rod group 20 and the second rod group 30 can be interchanged, making later maintenance and repair convenient. In addition, in the prior art, when folding a children's bed, the base structure needs to be lifted upwards by hand, and while lifting, the support member 10 needs to be held to prevent it from tipping over. However, when folding the children's bed of this application (see the aforementioned specific folding operation), only the support member 10 needs to be held by hand.

[0059] It is worth mentioning that both the first rod group 20 and the second rod group 30 are equipped with locking structures 40. During the use of the children's bed, even if one of the locking structures 40 loses its locking effect due to accidental contact, the other locking structure 40 can still ensure the stability of the children's bed and improve the safety of using the children's bed.

[0060] See Figure 1 , Figure 7 as well as Figure 8 When the children's bed is in the unfolded state, the first rail 21 and the second rail 31 extend along the first direction. The hinge point between the first rail 21 and the support member 10 is denoted as point B, and the hinge point between the second rail 31 and the support member 10 is denoted as point C. In the first direction, point C is located on the side of point B away from the hinge points of the two first rails 21.

[0061] The hinge point between the two first connecting rods 21 is the first connecting member 22. In this embodiment, point C is located on the side of point B away from the first connecting member 22 (in the first direction), that is, in... Figure 8 From the perspective, point C is set to the left of point B, that is, in the first direction (horizontal), point C is closer to the edge of the children's bed; when the children's bed is folded up, the first railing 21 can rotate to a vertical position and will not be blocked by point C. That is, during the folding up process, point C will not interfere with the first railing 21, and the children's bed can be folded up as much as possible (the size of the children's bed in the first direction is smaller after folding up), reducing the space occupied by the children's bed in the first direction after folding up, that is, avoiding the children's bed taking up a large storage space.

[0062] It should be noted that the first direction is as follows: Figure 8As shown in the X direction; in this embodiment, point C will not interfere with the first retaining rod 21, provided that the length of the first retaining rod 21 is greater than the height difference between point C and point B; in some embodiments, the length of the first retaining rod 21 is less than the height difference between point C and point B, that is, during the folding process of the children's bed, the first retaining rod 21 is always above point C, and naturally there will be no interference with point C, and it also falls within the protection scope of this application.

[0063] In some embodiments, two sets of second rod groups 30 are spaced apart along a second direction; when the children's bed is in the unfolded state, the second surrounding rods 31 extend along a first direction, and in the two sets of second rod groups 30, the distance from the hinge point of each second surrounding rod 31 to the bottom of the support member 10 is the same, and the second direction is perpendicular to the first direction.

[0064] In the same second rod group 30, the end of the second rod 31 away from the hinge point of the two second rods 31 (i.e. away from the second connector 33) is hinged to the support member 10. That is, in this embodiment, since there are two groups of second rod groups 30, there are a total of four support members 10, and the four support members 10 together form a children's bed. The distance from the hinge point (point C) of the second rod 31 and the support member 10 to the bottom of the support member 10 is the same. That is, when the children's bed is in the unfolded state, the installation height of each second rod 31 is consistent. The two groups of second rod groups 30 arranged at intervals along the second direction form an installation platform (a horizontally arranged platform) which can be used to install the bed board (which helps to ensure the flatness of the bed board after installation and improves the user experience of the children's bed). The second rod group 30 can stabilize the children's bed and also be used as a mounting frame for the bed board. There is no need to set up other structures for the installation of the bed board, which simplifies the structure of the children's bed, reduces the weight of the children's bed, facilitates the movement of the children's bed, and makes it more convenient to use.

[0065] It is worth mentioning that the bed board can be a single piece of board, which is then mounted on the second rod assembly 30 after the children's bed is unfolded; in some embodiments, the bed board can also be divided into two parts, one for the left side and one for the right side. Figure 3 The bed board is connected to the second rail 31 (view angle). The bed board can be fixed to the second rail 31 and can be opened and closed accordingly as the children's bed (second rail 31) is opened and closed, making it convenient to use.

[0066] It should be noted that in this embodiment, the support member 10 is rod-shaped, i.e., a support leg, extending vertically. The two sets of second rod groups 30 are installed at the same height, meaning that the two sets of second rod groups 30 are at the same height in the vertical direction. The second direction is as follows... Figure 2 Shown in the middle direction Y.

[0067] In some embodiments, the structure of the children's bed can also be other shapes and configurations, not limited to these. For example, in some embodiments, the support member 10 can also be plate-shaped. A children's bed only needs to be symmetrically provided with two plate-shaped support members 10 to meet the support requirements. The plate-shaped support member 10 is beneficial to improving the support of the children's bed.

[0068] See Figure 6 The locking structure 40 includes a spring pin 41, a locking rod 42, and a driving block 43. The spring pin 41 is inserted into the end of the first retaining rod 21 near the first connecting member 22 via the locking rod 42. The end of the first retaining rod 21 near the first connecting member 22 is provided with a mounting groove 211, and the locking rod 42 slides in the mounting groove 211. The first connecting member 22 is provided with a fixing groove 221 and a guide groove 222 that are connected to each other. The driving block 43 is configured to drive the spring pin 41 to move axially along the first retaining rod 21 and drive the locking rod 42 to slide from the fixing groove 221 to the guide groove 222 to release the locking state of the first retaining rod 21.

[0069] In this embodiment, only the first link group 20 is discussed as an example. The second link group 30 is similar to the first link group 20, and will not be described in detail here.

[0070] When the children's bed is in the unfolded state, the locking rod 42 is housed in the fixing groove 221 (under the elastic pressure of the spring pin 41, the locking rod 42 is pressed into the fixing groove 221). The first rails 21 on both sides of the first connecting member 22 are relatively stationary and the first rails 21 are in the locked state. When it is necessary to unlock the first rails 21, the driving block 43 is driven, and the driving block 43 drives the spring pin 41 to move. As the spring pin 41 moves, the locking rod 42 slides from the fixing groove 221 into the guide groove 222, completing the unlocking of the first rails 21. The first rails 21 can rotate relative to the first connecting member 22, realizing the folding operation of the children's bed. The structure is simple and easy to use.

[0071] When the children's bed switches from the folded form to the unfolded form, the first support rod 21 rotates relative to the first connector 22. During the rotation of the first support rod 21, the locking rod 42 slides along the guide groove 222 toward the fixing groove 221. When the locking rod 42 slides into the fixing groove 221, the spring pin 41 is fixed in the fixing groove 221 under the action of the elastic element, and the first support rod 21 is locked.

[0072] It is worth mentioning that the drive block 43 can be slidably connected to the first connector 22, which will not be described in detail here.

[0073] It should be noted that, as the name suggests, the spring pin 41 is a flexible pin that can be connected by a spring or other elastic element.

[0074] In some embodiments, the locking structure 40 may also be configured in other ways, such as providing a plug hole on the first arm 21 and connecting the plug holes on the two first arms 21 with a U-shaped plug to achieve relative stillness between the two first arms 21. When unlocking, it is only necessary to pull the plug out of the plug hole. It is not limited to this, and in some embodiments, it may also be configured in other ways.

[0075] See Figure 2-4 A linkage structure 50 connects the first linkage group 20 and the second linkage group 30. During the switching between the unfolded and folded forms of the children's bed, the linkage structure 50 is configured to transmit the movement of the first linkage group 20 to the second linkage group 30, so that the second linkage group 30 moves in coordination with the first linkage group 20.

[0076] In this embodiment, the first rod group 20 and the second rod group 30 connected between two adjacent support members 10 are discussed as an example. Through the linkage structure 50, the first rod group 20 and the second rod group 30 are connected as a whole. When the children's bed switches between its unfolded and folded forms (i.e., the folding or unfolding process), when the first rod group 20 moves downwards and folds (or when it moves upwards and unfolds, as discussed here, the folding of the first rod group 20 is taken as an example), it can drive the second rod group 30 to move downwards and fold together. This allows the first rod group 20 and the second rod group 30 to fold synchronously. The top (hinged with the first support rod 21) and bottom (hinged with the second support rod 31) of the support members 10 on both sides of the first rod group 20 (and the second rod group 30) can simultaneously move towards the middle (during the folding process), preventing the support members 10 from tilting. This improves the stability of the support members 10 during the folding process, facilitates smooth switching of the children's bed's state, and increases the efficiency of the switching.

[0077] In some embodiments, the linkage structure 50 includes a connecting rod 51, with both ends of the connecting rod 51 hinged to the first surrounding rod 21 and the second surrounding rod 31, respectively. The structure is simple, and the linkage between the first surrounding rod 21 and the second surrounding rod 31 can be achieved solely through the connecting rod 51. In this embodiment, one connecting rod 51 is provided. In some embodiments, two connecting rods 51 may be provided, respectively hinged between the first surrounding rod 21 and the second surrounding rod 31, which are respectively arranged opposite to each other (arranged opposite to each other along the extension direction of the support member 10 when the children's bed is in the unfolded form).

[0078] It is worth mentioning that in some embodiments, when the first rod group 20 and the second rod group 30 are connected by the linkage structure 50, the second rod group 30 does not need to be provided with the locking structure 40. When the first rod group 20 is locked by the locking structure 40, the second rod group 30 is also locked due to the presence of the linkage structure 50.

[0079] On the other hand, this application also relates to a children's bed, including any of the aforementioned railing components.

[0080] The technical solution provided in this application aims to connect the first retaining rod 21 and the stabilizing column 61 together through the stabilizing rod 62. During the folding process of the first rod group 20, the stabilizing rod 62 can limit the angle between the first retaining rod 21 and the vertical direction (i.e., limit the angle between the first retaining rod 21 and the first connecting member 22). The angle between the first retaining rod 21 and the first connecting member 22 changes gradually with the folding process. When the positions of the support members 10 on both sides of the first rod group 20 remain unchanged, the angle between the first retaining rod 21 and the first connecting member 22 is temporarily fixed, and the first connecting member 22 will not swing laterally. That is, at any time during the folding process of the children's bed, the relative position between the first retaining rod 21 and the first connecting member 22 is stable, which is conducive to the smooth folding of the children's bed.
