[0041] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0042] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or electrically connected or can communicate with each other; it can be directly connected, or indirectly connected through an intermediate medium, or the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0043] The bed frame and child bed in the present application will be described in detail below with reference to the drawings and specific embodiments.

[0044] The prior art can be that the height of the guardrail to the bed plate is too high, which is not conducive to the parent to hold out or put into the child bed inside the child bed, and the height of the guardrail will affect the operation of the parent.

[0045] To solve the above technical problems, the embodiment of the present application provides a bed frame, which comprises a base, a vertical rod, a surrounding rod assembly and an adjusting assembly; the vertical rod is arranged around the periphery of the base; the surrounding rod assembly is arranged between adjacent vertical rods; at least one group of the surrounding rod assembly is connected with the vertical rod through the adjusting assembly to realize the position adjustment of the surrounding rod assembly in the length direction of the vertical rod; wherein the adjusting assembly comprises a mounting seat, a lock rod, a lock hole and a driving block; the mounting seat is connected to the end of the surrounding rod assembly; the lock hole is arranged on the side of the vertical rod facing the surrounding rod assembly in the length direction of the vertical rod; the lock rod is provided with a linkage protrusion, and the lock rod is slidingly connected to the mounting seat; the driving block has a driving groove, and the linkage protrusion is embedded and slidingly connected to the driving groove; the moving direction of the driving block is not parallel to the moving direction of the lock rod, and when the driving block moves, the groove wall of the driving groove presses and drives the linkage protrusion to slide in the driving groove, so that the end of the lock rod enters or exits the lock hole. By arranging the adjusting assembly between the surrounding rod assembly and the vertical rod, the position of the surrounding rod assembly in the length direction of the vertical rod can be adjusted, that is, the height of the surrounding rod assembly can be adjusted, so that parents can easily hold or put children into the interior of the child bed, and the height of the surrounding rod assembly can be adjusted according to the height of the child to meet the interaction between parents and children during personal games. Details are described below.

[0046] Referring to Figures 1-6 and Figures 12-13 In an embodiment, the bed frame comprises a base 10, and a vertical rod 20 is arranged around the periphery of the base 10, and four vertical rods 20 are arranged in the embodiment; a surrounding rod assembly 30 is connected between adjacent two vertical rods 20 through an adjusting assembly 40; the surrounding rod assembly 30, the vertical rod 20 and the base 10 cooperatively enclose a space for children to use; the adjusting assembly 40 is arranged at the end of the surrounding rod assembly 30, and can realize the position adjustment of the surrounding rod assembly 30 in the length direction of the vertical rod 20, that is, the height of the surrounding rod assembly 30 can be adjusted, so that parents can easily hold or put children into the interior of the child bed.

[0047] It should be noted that the base 10 can ensure the stability of the bed frame, and can be connected through a connecting rod (as shown in Figure 1 and 2 ), but is not limited thereto.

[0048] In some embodiments, universal wheels can also be arranged at the bottom of the vertical rod 20, which can facilitate the movement of the bed frame and facilitate the carrying of the bed frame.

[0049] In this embodiment, the adjustment component 40 includes a mounting base 41, a locking rod 42, locking holes 44, and a driving block 45. The mounting base 41 is connected to the end of the retaining rod assembly 30. Multiple locking holes 44 are spaced apart along the length of the upright 20 and are located on the side of the upright 20 facing the retaining rod assembly 30. The locking rod 42 is slidably mounted on the mounting base 41 and has a linkage protrusion 43. The driving block 45 has a driving groove 451, and the linkage protrusion 43 is embedded in and slidably connected in the driving groove 451. The moving direction of the driving groove 451 is the same as the moving direction of the locking rod 42. The drive block 45 (i.e., drive groove 451) moves, and the groove wall of drive groove 451 presses against and drives the linkage protrusion 43 to slide within drive groove 451. That is, the groove wall of drive groove 451 applies a force to linkage protrusion 43. Under the action of this force, linkage protrusion 43 can reciprocate, thereby driving locking rod 42 to reciprocate, so that the end of locking rod 42 can enter or leave lock hole 44, realizing the locking and separation between the fence assembly 30 and the upright 20, which facilitates the position adjustment of fence assembly 30 in the height of upright 20.

[0050] It should be noted that in this embodiment, the locking rod 42 is elongated, and the moving direction of the drive groove 451 is not parallel to the moving direction of the locking rod 42, that is, the moving direction of the drive block 45 is angled to the length direction of the locking rod 42. In actual use, a driving force needs to be applied to the drive block 45 to make the drive block 45 (drive groove 451) move, thereby driving the reciprocating movement of the locking rod 42. This driving force comes from the side of the locking rod 42 (e.g., in this embodiment, as shown in the image). Figure 13 As shown, the driving force (perpendicular to the locking rod 42) acts on the driving block 45, meaning that the user can drive the driving block 45 by pressing the driving block 45 with their thumb or other driving methods, enabling one-handed operation. The structure is simple and easy to use.

[0051] See Figures 12-15 In one embodiment, the drive groove 451 is elongated, with two ends along its length: a first end 4511 and a second end 4512. The distance from the first end 4511 to the upright 20 is less than the distance from the second end 4512 to the upright 20 (i.e., Figure 13 In this embodiment, the length direction of the drive groove 451 is parallel to the moving direction of the locking rod 42. (The first end 4511 is located to the left of the second end 4512). Figure 13 The horizontal (horizontal) unevenness in the view allows the drive groove 451 to exert a force on the linkage protrusion 43 through its groove wall. That is, when the drive block 45 is driven, the linkage protrusion 43 moves along the direction from the first end 4511 to the second end 4512. Figure 13In the perspective, the linkage protrusion 43 moves to the right); when the surrounding rod assembly 30 is in the locked state, the linkage protrusion 43 is close to the first end 4511, and when the surrounding rod assembly 30 is in the unlocked state (the lock rod 42 is away from the lock hole 44), the linkage protrusion 43 is close to the second end 4512.

[0052] In actual use, the end of the lock rod 42 is inserted into the lock hole 44, and the surrounding rod assembly 30 is in the locked state; the user applies a driving force to the driving block 45, and the driving block 45 moves downward in the perspective, that is, the driving force is perpendicular to the lock rod 42. Figure 13 In the perspective, the driving force is perpendicular to the lock rod 42, that is, the driving block 45 moves downward, the groove wall of the driving groove 451 applies a force to the linkage protrusion 43, and as the driving groove 451 moves downward, the linkage protrusion 43 moves to the right, and the lock rod 42 moves to the right, and the end of the lock rod 42 close to the vertical rod 20 gradually moves out of the lock hole 44, until Figure 14 In the perspective, the driving force is perpendicular to the lock rod 42, that is, the driving block 45 moves downward, the groove wall of the driving groove 451 applies a force to the linkage protrusion 43, and as the driving groove 451 moves downward, the linkage protrusion 43 moves to the right, and the lock rod 42 moves to the right, and the end of the lock rod 42 close to the vertical rod 20 gradually moves out of the lock hole 44, until

[0053] It should be noted that, Figure 13 and Figure 14 The vertical rod 20 and the lock hole 44 are only schematic diagrams, and are convenient for understanding the scheme; in some embodiments, the driving groove 451 can also have other shapes, such as an arc shape or a polyline shape, and is not limited thereto, and can drive the linkage protrusion 43 to reciprocate according to actual design.

[0054] Referring to Figure 7 , Figure 8 and Figure 12 In an embodiment, the lock rod 42 includes a lock tongue portion 421 and a pull rod portion 422, the lock tongue portion 421 is connected to the pull rod portion 422 through a connecting structure 46, the linkage protrusion 43 is arranged on the pull rod portion 422, and an end of the lock tongue portion 421 away from the pull rod portion 422 is used to abut against the lock hole 44.

[0055] Through the split arrangement of the lock tongue portion 421 and the pull rod portion 422, the installation of the lock rod 42 can be facilitated, and different parts (the lock tongue portion 421 or the pull rod portion 422) can be replaced separately, thereby reducing the maintenance cost in the later period.

[0056] In the embodiment, the connecting structure 46 comprises a buckling block 461 and a buckling groove 462, the buckling block 461 buckles in the buckling groove 462 to realize the connection between the lock tongue part 421 and the pull rod part 422. In the embodiment, the buckling block 461 is arranged at the end of the pull rod part 422 close to the lock tongue part 421, and the buckling groove 462 is arranged at the end of the lock tongue part 421 close to the pull rod part 422.

[0057] In this way, the connection and installation of the lock tongue part 421 and the pull rod part 422 are facilitated. The buckling block 461 is buckled in the buckling groove 462 to realize the connection between the lock tongue part 421 and the pull rod part 422, which can ensure the force transmission between the two parts. The structure is simple, the processing and molding are convenient, and the production cost is reduced. In some embodiments, the buckling block 461 can also be arranged at the end of the lock tongue part 421 close to the pull rod part 422, and the buckling groove 462 can be arranged at the end of the pull rod part 422 close to the lock tongue part 421. In addition, in some embodiments, the connecting structure 46 can also be other forms of connection mode, which is not limited to this.

[0058] Referring to Figure 2 and Figures 6-10 In an embodiment, the mounting seat 41 comprises a first mounting sub-seat 411 and a second mounting sub-seat 412, the second mounting sub-seat 412 is rotationally connected with the first mounting sub-seat 411 through a rotating shaft 80, that is, the second mounting sub-seat 412 can rotate relative to the first mounting sub-seat 411. The lock tongue part 421 is slidably connected in the first mounting sub-seat 411, and the pull rod part 422 is slidably connected in the second mounting sub-seat 412. In the embodiment, the second mounting sub-seat 412 is rotated to realize the separation or connection between the buckling block 461 and the buckling groove 462.

[0059] It should be noted that, in the embodiment, the surrounding rod assembly 30 comprises a connecting piece 31, two lower surrounding rods 32 and two upper surrounding rods 33. The connecting piece 31 is connected between the two upper surrounding rods 33, and the end of the upper surrounding rod 33 away from the connecting piece 31 is connected with the second mounting sub-seat 412. Meanwhile, the connecting piece 31 is connected between the two lower surrounding rods 32, and the lower surrounding rod 32 can increase the strength of the surrounding rod assembly 30. The end of the lower surrounding rod 32 away from the connecting piece 31 is rotationally connected on the first mounting sub-seat 411. The upper surrounding rods 33 and the lower surrounding rods 32 on both sides of the connecting piece 31 can rotate relative to the connecting piece 31, thereby realizing the folding of the surrounding rod assembly 30.

[0060] In the storage use, when the upper surrounding rods 33 (lower surrounding rods 32) on both sides of the connecting piece 31 are rotated around the connecting piece 31, the end of the upper surrounding rod 33 away from the connecting piece 31 (the end connected with the second mounting base 412) drives the second mounting base 412 to rotate relative to the first mounting base 411 (at this time, the first mounting base 411 is locked in position by being inserted into the lock hole 44 through the lock tongue 421), and in the process of rotating the second mounting base 412, the buckling block 461 is separated from the buckling groove 462, so as to realize the folding storage of the surrounding rod assembly 30; in the actual use of the bed frame, the upper surrounding rods 33 (lower surrounding rods 32) folded on both sides of the connecting piece 31 are rotated to the use state, at this time, the buckling block 461 is buckled in the buckling groove 462, so as to realize the connection of the pull rod 422 and the lock tongue 421, which is simple in structure and convenient to use.

[0061] Referring to Figure 11 、 Figure 12 and Figure 15 In an embodiment, a first reset structure 50 is arranged between the lock rod 42 and the mounting base 41, the first reset structure 50 comprising a first mounting groove 51, a first reset spring 52, a first limiting groove 53 and a first limiting rod 54; the first mounting groove 51 and the first limiting groove 53 are arranged on the lock rod 42, the first limiting rod 54 is arranged through and slidably connected with the first limiting groove 53, and the first limiting rod 54 is fixedly arranged on the mounting base 41, and the first limiting groove 53 is used to limit the displacement of the lock rod 42; the first reset spring 52 is arranged in the first mounting groove 51, one end of the first reset spring 52 is abutted against the groove wall of the first mounting groove 51, and the other end is abutted against the first limiting rod 54; in addition, in the locked state, the end of the lock rod 42 close to the vertical rod 20 is inserted into the lock hole 44 under the action of the first reset spring 52.

[0062] In this way, when the lock rod 42 is rotated to the right (towards the vertical rod 20), the first reset spring 52 is compressed, and the first limiting rod 54 is inserted into the first limiting groove 53, so as to limit the displacement of the lock rod 42. Figure 13 、 15When the lock rod 42 moves, the first reset spring 52 is compressed under the extrusion of the first installation groove 51 groove wall (the first limiting rod 54 is fixedly arranged on the mounting seat 41, and the other end of the first reset spring 52 abuts against the first limiting rod 54, so that the end of the first reset spring 52 abutting against the first limiting rod 54 does not move with the lock rod 42); when the lock rod 42 moves, the first limiting groove 53 moves rightward along with the movement of the lock rod 42, while the first limiting rod 54 and the mounting seat 41 are always fixed and do not move; when the first limiting groove 53 moves to the left end thereof abutting against the first limiting rod 54, the first limiting groove 53 is blocked and cannot continue to move, that is, the size of the first limiting groove 53 in the movement direction of the lock rod 42 determines the size of the displacement of the lock rod 42; through the size of the first limiting groove 53 in the movement direction of the lock rod 42, the displacement of the lock rod 42 can be limited, so that the lock rod 42 does not slip out of the mounting seat 41 due to the too large displacement of the lock rod 42 moving rightward, and the lock rod 42 can also be ensured to completely separate from the lock hole 44. In addition, in the movement process of the lock rod 42 (the first limiting groove 53), the first limiting groove 53 provides a space for the first limiting rod 54 to avoid (that is, the first limiting rod 54 relatively slides in the first limiting groove 53), so as to avoid the interference of the lock rod 42 to the first limiting rod 54 when the lock rod 42 moves. After the end of the lock rod 42 close to the vertical rod 20 is separated from the lock hole 44, the surrounding rod assembly 30 is moved to a required position, and under the action of the first reset spring 52, the lock rod 42 is reset leftward, the end of the lock rod 42 close to the vertical rod 20 is inserted into the lock hole 44 after the adjustment of the surrounding rod assembly 30, and is kept in the lock hole 44.

[0063] In the embodiment, the first reset structure 50 can be arranged on the lock tongue portion 421 in the first installation sub-base 411, so that when the second installation sub-base 412 is separated from the first installation sub-base 411, the end of the lock tongue portion 421 close to the vertical rod 20 is always inserted into the lock hole 44, so that the stability of the structure is ensured and the convenience of accommodating the surrounding rod assembly 30 is ensured.

[0064] Referring to Figures 12-15 In an embodiment, the driving block 45 is slidably arranged in the mounting seat 41, and the second reset structure 60 is arranged between the driving block 45 and the mounting seat 41. The second reset structure 60 includes a second installation groove 61, a second reset spring 62, a second limiting groove 63 and a second limiting rod 64. The second installation groove 61 and the second limiting groove 63 are arranged on the driving block 45, the second limiting rod 64 is arranged in and slidably arranged in the second limiting groove 63, and the second limiting rod 64 is fixedly arranged on the mounting seat 41. The second limiting groove 63 is used for limiting the displacement of the driving block 45. The second reset spring 62 is arranged in the second installation groove 61, and one end of the first reset spring 52 abuts against the groove wall of the second installation groove 61 and the other end abuts against the second limiting rod 64.

[0065] In this way, when the driving block 45 is driven to use, the second reset spring 62 is compressed under the extrusion of the second installation groove 61, until the end of the locking rod 42 close to the upright rod 20 is away from the lock hole 44 (i.e. Figure 14 In the view angle, the linkage protrusion 43 moves from the first end 4511 to the second end 4512); after the surrounding rod assembly 30 is moved to the desired position, the driving force on the driving block 45 is removed, and under the action of the second reset spring 62, the locking rod 42 is reset to the left, until the end of the locking rod 42 close to the upright rod 20 is inserted into the lock hole 44 after the surrounding rod assembly 30 is adjusted, and is kept in the lock hole 44.

[0066] It should be noted that the second limiting groove 63 has a similar effect as the first limiting groove 53, which can prevent the driving block 45 from falling off the mounting seat 41, and at the same time provides a space for the second limiting rod 64, which will not be described here.

[0067] Referring to Figures 2-4 and Figure 6 In an embodiment, a sliding structure 70 is provided between the mounting seat 41 and the upright rod 20, which includes a sliding block 71 and a sliding groove 72 matched with the sliding block 71, and the sliding block 71 is slidingly connected in the sliding groove 72; in this embodiment, the sliding block 71 is arranged on the mounting seat 41, and the sliding groove 72 is arranged on the upright rod 20, but it is not limited thereto.

[0068] In this way, the contact area between the sliding block 71 and the sliding groove 72 is large, and when the surrounding rod assembly 30 is horizontally arranged between two upright rods 20, the static friction between the sliding block 71 and the sliding groove 72 can offset part of the gravity of the surrounding rod assembly 30, reducing the pressure on the end of the locking rod 42 and prolonging the service life of the locking rod 42; the sliding groove 72 has a guiding effect, so that the surrounding rod assembly 20 cannot move in other directions when it moves up and down (moves along the sliding groove 72), ensuring the stability of the connection between the mounting seat 41 and the upright rod 20, and controlling the relative position of the locking rod 42 and the lock hole 44 when the height of the surrounding rod assembly 30 is adjusted, which is conducive to the insertion of the locking rod 42 into the lock hole 44 and improves the efficiency of the height adjustment of the surrounding rod assembly 30; in addition, the contact area between the sliding block 71 and the sliding groove 72 is large, so that when the height of the surrounding rod assembly 30 is adjusted, the two ends of the surrounding rod assembly 30 can be adjusted in height at the same time, and the situation that one end is higher than the other end when the height is adjusted is less likely to occur; the adjustment of the surrounding rod assembly 30 is smooth.

[0069] On the other hand, the present application also relates to a children's bed comprising any of the foregoing bed frames.

[0070] The technical scheme provided in the embodiment of the application aims to adjust the position of the fence assembly in the length direction of the stand pole 20, i.e., the height of the fence assembly 30, by arranging the adjusting assembly 40 between the fence assembly 30 and the stand pole 20, so as to conveniently carry or put the child into or out of the child bed, and to adjust the height of the fence assembly 30 according to the height of the child to meet the interaction between the parent and the child during the game; by driving the driving block 45, the driving groove 451 on the driving block 45 exerts a force on the linkage protrusion 43, so that the linkage protrusion 43 (the lock rod 42) reciprocates, the end of the lock rod 42 approaches the end of the stand pole 20 to enter or leave the lock hole 44, when the end of the lock rod 42 enters the lock hole 44, the stability of the connection between the fence assembly 30 and the stand pole 20 can be ensured, when the end of the lock rod 42 leaves the lock hole 44, the fence assembly 30 can be moved up and down (in the length direction of the stand pole 20), and after reaching the appropriate position, the end of the lock rod 42 enters another lock hole 44 to be locked; the structure is simple and convenient to use.
