[0024] A telescopic rod, one end of which is rotatably connected to a connecting surrounding rod through a connecting assembly;

[0025] The telescopic sleeve is rotatably connected to another connecting fence at one end through another connecting component. The telescopic sleeve is sleeved on the telescopic rod and slides relative to the telescopic rod along its axial direction to lengthen or shorten the telescopic fence. The telescopic sleeve drives the telescopic rod to rotate through a positioning structure.

[0026] In one embodiment, the positioning structure includes a sliding groove and a positioning pin. The sliding groove is arranged along the axial direction of the telescopic rod. One of the telescopic rod and the telescopic sleeve is provided with the sliding groove, and the other is provided with the positioning pin.

[0054] The enclosure frame assembly is widely used in rocking beds and folding beds. The enclosure frame assembly usually consists of multiple enclosure rods enclosing a circular body, and a cloth cover is sleeved on the circular body. The cloth cover encloses to form a lying and sleeping space at the bottom and around. Due to the surrounding enclosure of the cloth cover, when observing a child lying and sleeping inside, it is very inconvenient to view from above.

[0055] In the related art, a foldable side enclosure frame is provided on one side of the main enclosure frame in the enclosure frame assembly to convert the rocking bed into a bedside bed. Springs and sliding sleeves are used at both ends of the side enclosure frame to limit the degree of freedom of the rotating joint, with a complex structure and cumbersome operation.

[0056] Based on the above problems, the present utility model proposes an enclosure frame assembly, aiming to provide an enclosure frame assembly with a simple structure and convenient operation.

[0057] Please refer to Figures 1 to 4 , in an embodiment of the present utility model, the enclosure frame assembly 100 includes:

[0058] A first enclosure frame 10, having a pair of main enclosure rods 11 and a main connecting enclosure rod 12 connected between the pair of main enclosure rods 11;

[0059] A second enclosure frame 20, including a pair of connecting enclosure rods 30 and a telescopic enclosure rod 40 disposed between the pair of connecting enclosure rods 30; the pair of connecting enclosure rods 30 are respectively rotatably connected to the pair of main enclosure rods 11, and the connecting enclosure rod 30 is rotatably connected to the main enclosure rod 11 along the direction of the first axis a; the telescopic enclosure rod 40 is rotatably connected to the connecting enclosure rod 30 along the first rotating shaft 50a, and the first rotating shaft 50a extends in a direction perpendicular to the telescopic enclosure rod 40;

[0060] The first rotating shaft 50a moves between a first position and a second position. In the first position, the extending direction of the first rotating shaft 50a is parallel to the extending direction of the first axis a, and the connecting enclosure rod 30 can rotate relative to the main enclosure rod 11 and stretch the telescopic enclosure rod 40.

[0061] The technical solution of the present utility model is such that a pair of connecting enclosing rods 30 are respectively rotatably connected to a pair of main enclosing rods 11, and the connecting enclosing rods 30 are rotatably connected to the main enclosing rods 11 along the direction of the first axis a. The telescopic enclosing rod 40 is rotatably connected to the connecting enclosing rod 30 along the first rotating shaft 50a, and the first rotating shaft 50a extends along a direction perpendicular to the telescopic enclosing rod 40, so that the first rotating shaft 50a can move between a first position and a second position; wherein, in the first position, the extending direction of the first rotating shaft 50a is parallel to the extending direction of the first axis a, so that the enclosing frame assembly 100 is in an unlocked state. At this time, the connecting enclosing rod 30 can rotate relative to the main enclosing rod 11 and the telescopic enclosing rod 40 can be stretched; while in the second position, the extending direction of the first rotating shaft 50a forms an angle with the extending direction of the first axis a, so that the enclosing frame assembly 100 is in a locked state. At this time, the connecting enclosing rod 30 cannot rotate relative to the main enclosing rod 11.

[0062] Therefore, during use, by changing the position of the first rotating shaft 50a, when the first rotating shaft 50a moves to the first position, the enclosing frame assembly 100 can be in an unlocked state, and the rocking bed can be smoothly converted into a bedside bed; and by changing the position of the first rotating shaft 50a, when the first rotating shaft 50a moves to the second position, the enclosing frame assembly 100 can be in a locked state to limit the degree of freedom of the rotating joint, replacing the use of springs and sliding sleeves at both ends of the side enclosing frame to limit the degree of freedom of the rotating joint. The structure is relatively simple and the operation is more convenient.

[0063] As some examples, the first enclosing frame 10 can be in a U-shaped tubular structure. The middle pipe section of the U-shaped tubular structure is the main connecting enclosing rod 12, and the two side pipe sections of the U-shaped tubular structure are a pair of main enclosing rods 11.

[0064] As some examples, the connecting enclosing rod 30 can be in an L-shaped tubular structure. One end of the L-shaped tubular structure is rotatably connected to the main enclosing rod 11, and the other end of the L-shaped tubular structure is rotatably connected to one end of the telescopic enclosing rod 40. Of course, in other embodiments, the connecting enclosing rod 30 can also be in a straight tubular structure, an arc-shaped tubular structure or other shaped structures.

[0065] In the actual application process, the first rotating shaft 50a can be directly installed on the telescopic enclosing rod 40, or can be installed on the connecting component 50 between the telescopic enclosing rod 40 and the main enclosing rod 11.

[0066] Optionally, in an embodiment of the present utility model, the first rotating shaft 50a is provided on the telescopic enclosing rod 40. When the telescopic enclosing rod 40 rotates around its axis c, the first rotating shaft 50a switches between the first position and the second position.

[0067] With such a setting, by directly mounting the first rotating shaft 50a on the telescopic surrounding rod 40, when the telescopic surrounding rod 40 is rotated so that the telescopic surrounding rod 40 rotates around its axis c, the first rotating shaft 50a can be switched between the first position and the second position, enabling the surrounding frame assembly 100 to smoothly switch between the locked state and the unlocked state.

[0068] Optionally, please refer to Figures 1 to 4 , in another embodiment of the present utility model, the surrounding frame assembly 100 further includes a connecting assembly 50 provided with a first rotating shaft 50a. Both ends of the connecting assembly 50 where the first rotating shaft 50a is located are respectively rotatably connected to the telescopic surrounding rod and the connecting surrounding rod.

[0069] With such a setting, by arranging the first rotating shaft 50a on the connecting assembly 50 to achieve the rotational connection between the telescopic surrounding rod 40 and the connecting surrounding rod 30 by means of the connecting assembly 50, it is possible to switch the first rotating shaft 50a between the first position and the second position only by controlling the rotation of the connecting assembly 50, making the operation more convenient.

[0070] As an example, the structures of the two connecting assemblies 50 are the same. In this case, when the telescopic surrounding rod 40 rotates around its axis c, the two connecting assemblies 50 can be synchronously switched between the first position and the second position, enabling the surrounding frame assembly 100 to smoothly switch between the locked state and the unlocked state.

[0071] It should be noted that in the second position, the connecting surrounding rod 30 forms an angle with the axis b of the connecting surrounding rod 30 relative to the telescopic surrounding rod 40 along the first axis a. That is, at this time, the first axis a forms an angle with the extending direction of the first rotating shaft 50a. Since the first axis a is not parallel to the axis b, a mutually restrictive effect is formed, which can limit the degree of freedom of the rotating joint, enabling the surrounding frame assembly 100 to be in the locked state;

[0072] In the first position, the connecting surrounding rod 30 is parallel to the axis b of the connecting surrounding rod 30 relative to the telescopic surrounding rod 40 along the first axis a. That is, at this time, the first axis a is parallel to the extending direction of the first rotating shaft 50a. Since the first axis a is parallel to the axis b, the degree of freedom of the rotating joint is no longer restricted, enabling the surrounding frame assembly 100 to be in the unlocked state.

[0073] Please refer to Figures 5 to 9, in an embodiment of the present utility model, the connection assembly 50 includes a fixed connection member 51 and a rotatable joint 52; the fixed connection member 51 is connected to the connection surrounding rod 30; the rotatable joint 52 is rotatably connected to the fixed connection member 51 and rotates around the axis line of the telescopic surrounding rod 40. One end of the telescopic surrounding rod 40 is rotatably connected to the rotatable joint 52 through a first rotating shaft 50a. The axis line d around which the rotatable joint 52 rotates relative to the fixed connection member 51 forms an angle with the axis line b around which the telescopic surrounding rod 40 rotates relative to the rotatable joint 52.

[0074] With such a setting, the rotatable joints 52 of the two connection assemblies 50 can be respectively rotatably connected to the corresponding fixed connection members 51 first, then the fixed connection members 51 of the two connection assemblies 50 are respectively connected to the two connection surrounding rods 30, and both ends of the telescopic surrounding rod 40 are respectively rotatably connected to the rotatable joints 52 of the two connection assemblies 50 through the first rotating shafts 50a, so that both ends of the telescopic surrounding rod 40 are rotatably connected to the two connection surrounding rods 30 through the two connection assemblies 50 respectively. And under the rotational connection between the rotatable joint 52 and the fixed connection member 51, the telescopic surrounding rod 40 can smoothly rotate along its axis line c.

[0075] It should be noted that the axis line b around which the telescopic surrounding rod 40 rotates relative to the rotatable joint 52 is the axis line b around which the connection surrounding rod 30 rotates relative to both ends of the telescopic surrounding rod 40 respectively.

[0076] As some examples, specifically, screws or pins can be used to respectively connect the fixed connection members 51 of the two connection assemblies 50 to the two connection surrounding rods 30.

[0077] Please refer to Figure 8 、 Figure 9 , in an embodiment of the present utility model, a rotating groove 511 is provided at one end of the fixed connection member 51, and a rotating head 521 is provided at one end of the rotatable joint 52. The rotating head 521 is in rotational cooperation with the rotating groove 511.

[0078] With such a setting, through the cooperation between the rotating head 521 and the rotating groove 511, the rotational connection between the rotatable joint 52 and the fixed connection member 51 is realized more reliably.

[0079] Please refer to Figure 8 、 Figure 9 , in an embodiment of the present utility model, a rotation limiting portion 5211 is provided at the end of the rotating head 521, and a limiting step 5111 is provided on the groove wall of the rotating groove 511. The rotation limiting portion 5211 abuts against the limiting step 5111.

[0080] With such a setting, when the rotating head 521 is installed in the rotating groove 511, the rotation limiting portion 5211 will abut against the limiting step 5111 to prevent the rotating head 521 from disengaging from the rotating groove 511 during use, thereby affecting the reliability of the rotational connection between the rotating head 521 and the rotating groove 511.

[0081] Please refer to Figure 8 、 Figure 9 In an embodiment of the present utility model, an installation opening 5112 penetrating through to the outer side wall of the fixed connecting member 51 is further provided on the groove wall of the rotating groove 511, and the rotating head 521 is installed into the rotating groove 511 from the installation opening 5112.

[0082] With such a setting, during the disassembly and assembly process, the rotating head 521 can be smoothly installed into the rotating groove 511 from the installation opening 5112, or the rotating head 521 can be smoothly removed from the installation opening 5112 to achieve convenient disassembly and assembly of the rotating head 521.

[0083] Please refer to Figures 6 to 9 In an embodiment of the present utility model, one end of the fixed connecting member 51 and the rotatable joint 52 is inserted and connected into the connecting fence 30.

[0084] With such a setting, the installation reliability between the connecting assembly 50 and the connecting fence 30 can be improved, and at the same time, the installation opening 5112 on the fixed connecting member 51 can be blocked to prevent the rotating head 521 from disengaging from the installation opening 5112 during use, thereby affecting the reliability of the rotational connection between the rotating head 521 and the rotating groove 511.

[0085] As some examples, the rotatable joint 52 includes a connected first rotating end and a second rotating end, the rotating head 521 is connected to the end of the first rotating end far from the second rotating end, the first rotating ends of the two connecting assemblies 50 are respectively inserted into the two connecting fences 30, and the second rotating ends of the two connecting assemblies 50 are respectively rotatably connected to both ends of the telescopic fence 40.

[0086] Please refer to Figure 7 、 Figure 10 In an embodiment of the present utility model, one of the rotatable joint 52 of at least one connecting assembly 50 and the connecting fence 30 connected thereto is provided with a first limiting member, and the other of them is provided with a first limiting groove 31, and the first limiting member cooperates with the first limiting groove 31 to limit the rotation angle of the telescopic fence 40 around its axis c.

[0087] With such a setting, the rotation angle of the telescopic fence 40 around its axis c can be limited by the cooperation between the first limiting member and the first limiting groove 31, so that the telescopic fence 40 can drive the connecting assembly 50 to switch between the first position and the second position, and can accurately stay at the first position or the second position.

[0088] In one embodiment, a first limiting member may be provided on the rotatable joint 52 of one of the connecting components 50, and a first limiting groove 31 may be provided on the connecting fence 30 connected thereto; alternatively, a first limiting member may be provided on the rotatable joint 52 of the other connecting component 50, and a first limiting groove 31 may be provided on the connecting fence 30 connected thereto.

[0089] In another embodiment, first limiting members may be provided on the rotatable joints 52 of both connecting components 50, and first limiting grooves 31 may be provided on both connecting fences 30.

[0090] As some embodiments, the first limiting member may be a spring pin, and the first limiting groove 31 may be an arc-shaped groove.

[0091] Please refer to Figure 7 , in one embodiment of the present utility model, joint heads 41 are provided at both ends of the telescopic fence 40, and each joint head 41 is rotatably connected to a connecting component 50 through a first rotating shaft 50a.

[0092] With such a setting, the joint heads 41 at both ends of the telescopic fence 40 are respectively rotatably connected to two connecting components 50 through the first rotating shafts 50a, making the rotational connection between the two ends of the telescopic fence 40 and the two connecting fences 30 more reliable through the connecting components 50.

[0093] Please refer to Figure 7 , in one embodiment of the present utility model, one end of each joint head 41 is rotatably connected to a connecting component 50 through a first rotating shaft 50a, and the other end of each joint head 41 is inserted into one end of the telescopic fence 40; in this way, the connection reliability between the joint head 41 and the telescopic fence 40 can be improved.

[0094] As some examples, the joint head 41 can be connected to the telescopic fence 40 using screws or pins.

[0095] Please refer to Figure 6 , Figure 7 , Figure 11 , Figure 12 , in one embodiment of the present utility model, the telescopic fence 40 includes a telescopic rod 42 and a telescopic sleeve 43; one end of the telescopic rod 42 is rotatably connected to a connecting fence 30 through a connecting component 50; one end of the telescopic sleeve 43 is rotatably connected to another connecting fence 30 through another connecting component 50, the telescopic sleeve 43 is sleeved on the telescopic rod 42 and slides axially relative to the telescopic rod 42 to extend or shorten the telescopic fence 40, and the telescopic sleeve 43 drives the telescopic rod 42 to rotate through a positioning structure.

[0096] With such a setting, through the sliding fit between the telescopic rod 42 and the telescopic sleeve 43, the telescopic fence rod 40 can be extended or shortened more smoothly. Additionally, under the action of the positioning structure, when the telescopic sleeve 43 rotates around its axis, it can drive the telescopic rod 42 and the associated joint head 41 to rotate, preventing relative rotation between the telescopic rod 42 and the telescopic sleeve 43 and affecting the locking and unlocking effects of the enclosure assembly 100.

[0097] Please refer to Figure 7 , in an embodiment of the present utility model, the positioning structure includes a chute 421 and a positioning pin 431. The chute 421 is arranged along the axial direction of the telescopic rod 42. One of the telescopic rod 42 and the telescopic sleeve 43 is provided with the chute 421, and the other is provided with the positioning pin 431. The positioning pin 431 is in sliding fit with the chute 421.

[0098] With such a setting, during the installation process, the telescopic rod 42 can be smoothly inserted into the telescopic sleeve 43 after aligning the chute 421 with the positioning pin 431. This can not only prevent relative rotation between the telescopic rod 42 and the telescopic sleeve 43 but also guide the relative sliding between the telescopic rod 42 and the telescopic sleeve 43 under the cooperation of the chute 421 and the positioning pin 431, thereby improving the smoothness of the telescopic fence rod 40 during the extension or shortening process.

[0099] As an example, the chute 421 can also be a limiting groove to limit the sliding distance between the telescopic rod 42 and the telescopic sleeve 43 under the cooperation of the limiting groove and the positioning pin 431, thereby restricting the extension or shortening distance of the telescopic fence rod 40.

[0100] Please refer to Figure 6 、 Figure 7 , in an embodiment of the present utility model, the axis a of the relative rotation of the connecting fence rod 30 with respect to the main fence rod 11 coincides with the axis of one end of the connecting fence rod 30 itself.

[0101] With such a setting, one end of a pair of connecting fence rods 30 can rotate around its own axis with respect to a pair of main fence rods 11 respectively, making the rotational connection of one end of a pair of connecting fence rods 30 with respect to a pair of main fence rods 11 more reliable.

[0102] Please refer to Figure 6 、 Figure 7 , in an embodiment of the present utility model, one of at least one connecting fence rod 30 and the main fence rod 11 connected thereto is provided with a second limiting member, and the other is provided with a second limiting groove 13. The second limiting member is in cooperation with the second limiting groove 13 to limit the rotation angle of the connecting fence rod 30 with respect to the main fence rod 11.

[0103] With such a setting, the cooperation between the second limiting member and the second limiting groove 13 can limit the rotation angle of one end of the connecting surrounding rod 30 relative to the main surrounding rod 11, so that the surrounding frame assembly 100 can accurately stay in the first state or the second state.

[0104] In one embodiment, a second limiting member can be provided on one of the connecting surrounding rods 30, and a second limiting groove 13 can be provided on the main surrounding rod 11 connected thereto.

[0105] In another embodiment, second limiting members can be provided on both connecting surrounding rods 30, and second limiting grooves 13 can be provided on both main surrounding rods 11.

[0106] As some embodiments, the second limiting member can be a spring pin, and the second limiting groove 13 can be an arc-shaped groove.

[0107] Optionally, in an embodiment of the present utility model, please refer to Figure 1 , when in the first position, the first surrounding frame 10 and the second surrounding frame 20 together enclose a frame body with an upward opening;

[0108] Please refer to Figure 12 , when in the second position, the first surrounding frame 10 and the second surrounding frame 20 enclose a frame body, and the frame body has an upper side opening with an upward opening and a lateral opening with a lateral opening;

[0109] When in the first position, the height of the position where the telescopic surrounding rod 40 is located is the same as the height of the position where the main surrounding rod 11 is located; when in the second position, the height of the position where the telescopic surrounding rod 40 is located is lower than the height of the position where the main surrounding rod 11 is located.

[0110] With such a setting, when in the first position, by making the first surrounding frame 10 and the second surrounding frame 20 together enclose a frame body with an upward opening, at this time, the crib using this frame body can be used as a rocking crib; and when in the second position, by making the first surrounding frame 10 and the second surrounding frame 20 enclose a frame body, and the frame body has an upper side opening with an upward opening and a lateral opening with a lateral opening, at this time, the crib using this frame body can be used as a bedside crib.

[0111] It should be noted that the surrounding frame assembly 100 has a first state and a second state. When the surrounding frame assembly 100 is in the first state, the first surrounding frame 10 and the second surrounding frame 20 are on the same plane. At this time, the telescopic surrounding rod 40 can be rotated so that the telescopic surrounding rod 40 rotates around its axis c to the connecting assembly 50 in the second position to lock the surrounding frame assembly 100 in the first state; when the surrounding frame assembly 100 is in the second state, the telescopic surrounding rod 40 is located below one side of the plane where the first surrounding frame 10 is located. At this time, the rocking crib can be converted into a bedside crib.

[0112] Please refer to Figure 5 、Figure 11 , Figure 12 , in an embodiment of the present utility model, when the enclosure assembly 100 switches from the first state to the second state, one end of the connecting rod 30 connected to the main enclosure rod 11 rotates clockwise relative to the main enclosure rod 11 it is connected to, and the other end of the connecting rod 30 connected to the main enclosure rod 11 rotates counterclockwise relative to the main enclosure rod 11 it is connected to. The other ends of the two connecting rods 30 rotate relative to the two ends of the telescopic rod 40 respectively, and the telescopic rod 40 extends and moves to the side lower than the first enclosure 10 to convert the rocking bed into a bedside bed;

[0113] When the enclosure assembly 100 switches from the second state to the first state, one end of the connecting rod 30 connected to the main enclosure rod 11 rotates counterclockwise relative to the main enclosure rod 11 it is connected to, and the other end of the connecting rod 30 connected to the main enclosure rod 11 rotates clockwise relative to the main enclosure rod 11 it is connected to. The other ends of the two connecting rods 30 rotate relative to the two ends of the telescopic rod 40 respectively, and the telescopic rod 40 shortens and moves towards the plane where the first enclosure 10 is located to convert the bedside bed into a rocking bed.

[0114] In this embodiment, the enclosure assembly 100 can switch from the first state to the second state in the following two ways:

[0115] Method 1: Pull the two connecting rods 30. One connecting rod 30 rotates clockwise and drives the telescopic sleeve 43 to move left and down through the connecting assembly 50 and the joint head 41 connected to it. At the same time, the other connecting rod 30 rotates counterclockwise and drives the telescopic rod 42 to move right and down through the connecting assembly 50 and the joint head 41 connected to it. At the same time, the telescopic rod 42 and the telescopic sleeve 43 move towards the left and right ends respectively until the two connecting rods 30 rotate to the position where the second limiting member is limited by the second limiting groove 13.

[0116] Method 2: Press the telescopic sleeve 43 downwards. One connecting rod 30 is driven to rotate counterclockwise through the connecting assembly 50 and the joint head 41 connected to it. At the same time, the telescopic sleeve 43 moves right and down. At the same time, the telescopic rod 42 moves in the telescopic sleeve 43, and the joint head 41 and the connecting assembly 50 move along with the telescopic rod 42 to drive the other connecting rod to rotate clockwise until the two connecting rods 30 rotate to the position where the second limiting member is limited by the second limiting groove 13.

[0117] It should be noted that the process of converting from the second state to the first state is opposite to the process of converting from the first state to the second state, and will not be elaborated here one by one.

[0118] Please refer to Figure 11 , Figure 12, the present utility model also provides a children's bed 1000, which includes a chassis 200 and a surrounding frame assembly 100. The specific structure of the surrounding frame assembly 100 refers to the above embodiments. Since this children's bed 1000 adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one. Among them, the surrounding frame assembly 100 is arranged on the chassis 200.

[0119] Taking the rocking bed as an example in this embodiment: The chassis 200 is connected to the first surrounding frame 10 of the surrounding frame assembly 100 to form a support; a cloth cover is arranged on the surrounding frame assembly 100 to form a space for lying and sleeping. When the surrounding frame assembly 100 is in the first state, the first surrounding frame 10 and the second surrounding frame 20 are in the same plane. At this time, the cloth cover can enclose a space closed on all four sides, and at the same time, the cloth cover can form an upward opening; when the surrounding frame assembly 100 is converted from the first state to the second state, the telescopic fence 40 is located below the plane where the first surrounding frame 10 is located. At this time, the cloth cover can form an upward opening with a direction and a lateral opening facing the side, so that a gap can be exposed on the side of the telescopic fence 40 of the cloth cover to facilitate observing the situation inside the cloth cover.

[0120] The above is only an exemplary embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present utility model.
