Description

Technical Field

[0001] This application relates to the technical field of furniture supplies, and particularly to an adjustable-length bed frame and bed. Background Art

[0002] A bed frame is an important piece of furniture for supporting a mattress. The structure of a traditional bed frame is relatively fixed. Once it is manufactured, its length is difficult to adjust, which limits the applicable range of the bed frame and cannot flexibly adapt to the space requirements of different users.

[0003] In related technologies, in order to achieve the adjustment of the length of the bed frame, a sliding component is mostly provided in the bed rails on both sides of the bed board, so that the bed board can move a certain distance relative to the headboard to realize the stretching and extension of the bed frame. However, this setting method will cause a gap to be generated between the bed board and the headboard when the bed board moves relative to the headboard, and an additional movable board needs to be provided to fill this gap to make the entire bed board flat. The length that can be stretched by this stretching method is fixed, which is not conducive to flexibly adjusting the length of the bed frame and cannot meet the different needs of users.

Detailed implementation manner

[0044] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0045] In the present application, the orientation or positional relationship indicated by terms such as "upper" and "lower" is based on the orientation or positional relationship shown in the accompanying drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit that the indicated device, element or component must have a specific orientation, or be constructed and operated in a specific orientation.

[0046] Moreover, in addition to being able to represent the orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present application can be understood according to the specific situation.

[0047] In addition, the terms "set", "connect", and "be connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there is internal communication between two devices, elements or components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific situation.

[0048] In addition, terms such as "first" and "second" are mainly used to distinguish different devices, components or parts (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, components or parts. Unless otherwise specified, the meaning of "a plurality" is two or more.

[0049] In daily life, a bed is the most commonly used furniture for people to sleep and rest. Existing beds usually include a bed frame and a mattress, and the mattress can be placed on the bed frame. Users of different heights have different requirements for the overall length of the bed frame.

[0050] Generally speaking, bed frames are divided into three types. One is the frame structure, which usually refers to a plank bed; the second is the box frame structure, where the bed frame is spliced by four wooden boxes; the third is the pneumatic structure, where the bed frame is a bed box with a lid. However, no matter which structure the bed frame is, usually after the bed frame is made, its length is difficult to adjust and cannot meet the needs of users of different heights.

[0051] In the related art, most often a sliding component (such as a pull rod and a pull rod chute) is arranged in the bed rails on both sides of the bed frame. The sliding components are respectively connected to the headboard and the bed board. By pulling the headboard, the headboard can move a certain distance relative to the bed board to achieve the elongation of the overall length of the bed frame. However, in this way, although the elongation of the bed frame can be achieved, after elongation, a gap will be generated between the headboard and the bed board, and there is usually no support or weak support at the gap, which greatly affects the support of the bed frame.

[0052] In view of this, the embodiments of the present application disclose an adjustable-length bed frame and bed. By providing an adjustment component, the adjustment component is connected to the first mounting rod, and the adjustment component can make the first mounting rod move relative to the second mounting rod in the first direction, which helps to flexibly adjust the distance between the first mounting rod and the second mounting rod through the adjustment component, and further can flexibly adjust the overall length of the bed frame. Moreover, the adjustment component is located between any first mounting rod and the second mounting rod, so that while the length of the bed frame can be flexibly adjusted, the support inside the bed frame is not affected. On the other hand, the sliding rod slidably penetrates through the first connecting rod, so that when the first mounting rod slides relative to the second mounting rod in the first direction away from the second mounting rod, the sliding rod can slide along the first connecting rod, thereby filling the gap between the first mounting rod and the second mounting rod, and further helping to improve the support of the bed frame body.

[0053] The technical solutions of the present application will be further described below in conjunction with the embodiments and the drawings.

[0054] Please refer to Figure 1 , Figure 1It is a schematic structural diagram of an adjustable-length bed frame disclosed in an embodiment of the present application. The adjustable-length bed frame 100 disclosed in the present application includes a bed frame main body 1 and an adjustment assembly 2. The bed frame main body 1 includes two first mounting rods 11, a second mounting rod 12, two first connecting rods 13, and a sliding rod 14. The two first mounting rods 11 are arranged oppositely and at intervals along the first direction X. The second mounting rod 12 is located between the two first mounting rods 11 along the first direction X. The two first connecting rods 13 both extend along the first direction X, and the two first connecting rods 13 are respectively located at both ends of the second mounting rod 12 along the second direction Y. The first connecting rod 13 passes through the second mounting rod 12, and both ends of the first connecting rod 13 are arranged oppositely to the first mounting rod 11. A sliding rod 14 is sleeved on each first connecting rod 13. The sliding rod 14 extends along the first direction X, and the sliding rod 14 is connected to the first mounting rod 11. The sliding rod 14 is slidable relative to the first connecting rod 13 along the first direction X. The adjustment assembly 2 is located between any one of the first mounting rods 11 and the second mounting rod 12. The adjustment assembly 2 is connected to the first mounting rod 11. The adjustment assembly 2 is connected to the sliding rod 14. The adjustment assembly 2 is configured to move the first mounting rod 11 relative to the second mounting rod 12 along the first direction X to adjust the distance between the first mounting rod 11 and the second mounting rod 12 in the first direction X. Wherein, the second direction Y intersects with the first direction X.

[0055] By arranging two first mounting rods 11 that are arranged oppositely and at intervals along the first direction X, the second mounting rod 12 is located between the two first mounting rods 11 along the first direction X, and the adjustment assembly 2 is located between any one of the first mounting rods 11 and the second mounting rod 12. The adjustment assembly 2 is connected to the first mounting rod 11. The adjustment assembly 2 is configured to move the first mounting rod 11 relative to the second mounting rod 12 along the first direction X to adjust the distance between the first mounting rod 11 and the second mounting rod 12 in the first direction X. This setting method helps to flexibly adjust the distance between the first mounting rod 11 and the second mounting rod 12 through the adjustment assembly 2, and further helps to be able to flexibly adjust the overall length of the bed frame 100 according to different needs of the user for the length of the bed frame 100.

[0056] In addition, by arranging the adjustment device between the first mounting rod 11 and the second mounting rod 12, it helps to not affect the internal support of the bed frame 100 when adjusting the distance between the first mounting rod 11 and the second mounting rod 12 in the first direction X.

[0057] In addition, the adjustment assembly 2 is also connected to the sliding rod 14, and the sliding rod 14 is slidably connected to the first connecting rod 13, which helps the sliding rod 14 to slide along the first connecting rod 13 when flexibly adjusting the distance between the first mounting rod 11 and the second mounting rod 12 through the adjustment assembly 2, so as to fill the gap between the first mounting rod 11 and the second mounting rod 12, and further helps to improve the overall support of the bed frame main body 1.

[0058] It is understandable that the adjusting assembly 2 moves the first mounting rod 11 relative to the second mounting rod 12 along the first direction X. The adjusting assembly 2 can be an electric adjusting assembly 2 or a manual adjusting assembly 2. Examples will be given separately below.

[0059] In some embodiments, refer to Figure 1 , a first connecting portion 111 is provided on the first mounting rod 11. The adjusting assembly 2 includes a main body member 21 and a first adjusting member 22 connected to the main body member 21, and the first adjusting member 22 is also connected to the first connecting portion 111, so that the first mounting rod 11 is movable relative to the main body member 21 along the first direction X. This setting method helps the first mounting rod 11 to be movable relative to the main body member 21 along the first direction X through the first adjusting member 22, thereby helping to adjust the distance between the first mounting rod 11 and the main body member 21, and thus helping to adjust the distance between the first mounting rod 11 and the second mounting rod 12 to adjust the overall length of the bed frame 100.

[0060] It is understandable that there can be various embodiments for the above-mentioned first connecting portion 111, main body member 21, and first adjusting member 22. Taking the adjusting assembly 2 as an electric adjusting assembly as an example:

[0061] In one example, the first connecting portion 111 is a rack, the main body member 21 is a motor, and the first adjusting member 22 is a gear. A rack is provided on the first mounting rod 11. The adjusting assembly 2 includes a gear and a motor connected to the gear. By driving the gear to rotate by the motor, the rack can be movable relative to the gear along the first direction X, and further the rack can drive the first mounting rod 11 to be movable relative to the main body member 21 along the first direction X. Using a gear and a rack helps to precisely control the moving distance through the pitch and the number of teeth, and thus helps to precisely adjust the distance between the first mounting rod 11 and the main body member 21, and thus helps to precisely adjust the distance between the first mounting rod 11 and the second mounting rod 12 to precisely adjust the overall length of the bed frame 100.

[0062] In another example, the first connecting portion 111 and the first adjusting member 22 can be a lead screw-nut structure, which can be a sliding lead screw or a ball screw. Taking the ball screw as an example, the first connecting portion 111 is a nut, the first adjusting member 22 is a screw, balls are arranged between the nut and the screw, and the main body member 21 is a motor. A nut is provided on the first mounting rod 11. The adjusting assembly 2 includes a screw and a motor connected to the screw. By driving the screw to rotate through the motor, the balls are driven to move the nut relative to the gear in the first direction X, so that the nut can drive the first mounting rod 11 to move relative to the main body member 21 in the first direction X. Using a ball screw helps to reduce the friction between the nut and the screw, thereby helping to improve the adjustment efficiency of the length of the bed frame 100 and also helping to improve the overall service life of the bed frame 100.

[0063] It can be understood that the above motor can be a servo motor, a synchronous motor, etc., and the present embodiment does not make specific limitations on this.

[0064] Taking the adjusting assembly 2 as a manual adjusting assembly 2 as an example.

[0065] In one example, the first connecting portion 111 is a rack, the main body member 21 is a handwheel, and the first adjusting member 22 is a gear. A rack is provided on the first mounting rod 11. The adjusting assembly 2 includes a gear and a handwheel connected to the gear. By manually rotating the handwheel to drive the gear to rotate, the rack can move relative to the gear in the first direction X, so that the rack can drive the first mounting rod 11 to move relative to the main body member 21 in the first direction X. Using manually controlled gears and racks helps to reduce the overall weight and noise of the bed frame 100 compared with electric control.

[0066] In another example, the first connecting portion 111 is a nut and the first adjusting member 22 is a screw. A nut is provided on the first mounting rod 11. The adjusting assembly 2 includes a screw and the main body member 21 connected to the screw. By manually controlling the rotation of the screw, the nut can drive the first mounting rod 11 to move relative to the main body member 21 in the first direction X. Using manually controlled nuts and screws helps to improve the overall portability of the bed frame 100 compared with electric control.

[0067] Optionally, please refer to Figure 1 , the adjusting assembly 2 is also connected to the second mounting rod 12, and the adjusting assembly 2 can also move in the first direction X to adjust the distance between the adjusting assembly 2 and the second mounting rod 12 in the first direction X. The adjustment of the length of the bed frame 100 can be achieved by adjusting the distance between the first mounting rod 11 and the adjusting assembly 2, or by adjusting the distance within the second mounting rod 12 and the adjusting assembly 2, which helps to improve the flexibility of adjusting the length of the bed frame 100.

[0068] In some embodiments, please refer toFigure 1 On the second mounting rod 12, a second connecting portion 121 is provided, and the adjusting assembly 2 further includes a second adjusting member 23. Along the first direction X, the first adjusting member 22 is connected to one end of the main body member 21 facing the first mounting rod 11, and the second adjusting member 23 is connected to one end of the main body member 21 facing the second mounting rod 12. And the second adjusting member 23 is further connected to the second connecting portion 121, so that the main body member 21 can move along the first direction X. This setting method helps the second mounting rod 12 to be movable relative to the main body member 21 along the first direction X through the second adjusting member 23, thereby helping to adjust the distance between the second mounting rod 12 and the main body member 21, and thus helping to adjust the distance between the first mounting rod 11 and the second mounting rod 12 to adjust the overall length of the bed frame 100. On the other hand, it helps to make the distances between the first mounting rod 11 and the second mounting rod 12 and the adjusting assembly 2 adjustable, thereby helping to increase the length adjustment range between the first mounting rod 11 and the second mounting rod 12, and further helping to increase the adjustment range of the overall length of the bed frame 100.

[0069] It can be understood that there are also various embodiments for the second connecting portion 121 and the second adjusting member 23, which are the same as the first connecting portion 111 and the first adjusting member 22. Taking the adjusting assembly 2 as an electric adjusting assembly 2 as an example, in one example, the second connecting portion 121 is a rack, and the second adjusting member 23 is a gear. At this time, the main body member 21 is a two-way motor. In another example, the second connecting portion 121 is a nut, and the second adjusting member 23 is a screw rod. At this time, the main body member 21 is a two-way motor. Taking the adjusting assembly 2 as a manual adjusting assembly 2 as an example, in one example, the second connecting portion 121 is a rack, and the second adjusting member 23 is a gear. At this time, the main body member 21 is a handwheel. In another example, the second connecting portion 121 is a nut, and the second adjusting member 23 is a screw rod. This embodiment will not be elaborated herein.

[0070] Optionally, please refer to Figure 1 , the first adjusting member 22 and the second adjusting member 23 include screw rods, both the first connecting portion 111 and the second connecting portion 121 are threaded holes, the first adjusting member is threadedly connected to the first connecting portion 111, and the second adjusting member is threadedly connected to the second connecting portion 121. The adjusting assembly 2 further includes a knob 24, and the knob 24 is provided at one end of both the first adjusting member 22 and the second adjusting member 23. Through the threaded connection between the screw rod and the threaded hole, and a knob 24 is provided at one end of the screw rod, by rotating the knob 24, the screw rod can rotate relative to the nut, and thus the screw rod can drive the main body member 21 to move along the first direction X, thereby helping to adjust the distances between the first mounting rod 11 and the second mounting rod 12 and the main body member 21, and further helping to adjust the length of the overall bed frame 100.

[0071] In addition, adopting the cooperation mode of the screw rod and the spiral hole helps to improve the operation convenience and structural simplicity of the adjusting assembly 2, and further helps to improve the convenience of the user in assembling the bed frame 100 and adjusting the length of the bed frame 100.

[0072] It can be understood that the materials of the above-mentioned screw rod, nut and main body part 21 can be carbon steel, stainless steel, alloy steel or copper. Carbon steel has low cost, high strength and hardness. Using carbon steel as the material of the screw rod, nut and main body part 21 helps to improve the economy and durability of the screw rod and nut. Stainless steel is corrosion-resistant and has high strength. Using stainless steel as the material of the screw rod, nut and main body part 21 helps to improve the corrosion resistance and service life of the screw rod and nut. Alloy steel can withstand large external forces. Using alloy steel as the material of the screw rod, nut and main body part 21 helps to improve the durability of the screw rod and nut. Copper is not easy to rust and has a wide range of applications. Using copper as the material of the screw rod, nut and main body part 21 helps to improve the corrosion resistance and application range of the screw rod and nut. The materials of the screw rod, nut and main body part 21 are not specifically limited in this embodiment.

[0073] This embodiment will be described by taking the first adjusting member and the second adjusting member including a screw rod, and the first connecting portion and the second connecting portion being spiral holes as an example.

[0074] In some embodiments, please refer to Figure 1 and Figure 2 , Figure 2 are schematic structural diagrams of the adjusting assembly and the limiting assembly disclosed in the embodiments of the present application. Optionally, the main body part 21 is provided with a hollow interior, that is, the main body part is a hollow frame structure. Thus, while using the main body part to play a role in internally supporting the first mounting rod 11 and the second mounting rod 12, the overall weight of the bed frame 100 can also be reduced.

[0075] Optionally, the first adjusting member 22 penetrates through one side of the main body part 21 adjacent to the first mounting rod 11 in the first direction X. One end of the first adjusting member 22 is located in the hollow part 211 of the main body part, and the other end of the first adjusting member 22 is connected to the first connecting portion 111. This setting method can drive the adjusting assembly 2 to move in the first direction X by rotating the first adjusting member 22, which helps to improve the operation convenience of the first adjusting member 22, and at the same time helps to make the structure of the first adjusting member 22 and the main body part 21 more compact.

[0076] Accordingly, the second adjusting member 23 is disposed on one side of the main body member 21 adjacent to the second mounting rod 12 along the first direction X. One end of the second adjusting member 23 is located in the hollow portion 211 of the main body portion, and the other end of the first adjusting member 22 is connected to the first connecting portion 111. This setting method can drive the adjusting assembly 2 to move along the first direction X by rotating the second adjusting member 23, which helps to improve the operation convenience of the second adjusting member 23, and at the same time helps to make the structure of the second adjusting member 23 and the main body member 21 more compact.

[0077] Optionally, knobs 24 are provided at one ends of the first adjusting member 22 and the second adjusting member 23 located in the hollow portion 211 of the main body member 21. By passing the first adjusting member 22 and the second adjusting member 23 through the main body member 21, and knobs 24 are provided at one ends of the first adjusting member 22 and the second adjusting member located in the hollow portion 211 of the main body member 21, it helps the first adjusting member 22 and the second adjusting member 23 to rotate through the knobs 24 so that there is no interference between them, thereby enabling the distances between the main body member 21 and the first mounting rod 11 and the second mounting rod 12 along the first direction X to be adjusted respectively. Furthermore, it helps to improve the flexibility of the overall length adjustment of the bed frame 100.

[0078] It can be understood that the material of the above-mentioned knob 24 can be plastic or metal. Plastic is cheaper and lighter in weight. Using a plastic knob 24 helps to improve the economy and portability of the knob 24. Metal has stronger rigidity. Using a metal knob 24 helps to improve the service life of the knob 24.

[0079] In some embodiments, second connecting rods 112 are provided at both ends of the two first mounting rods 11. The second connecting rods 112 are arranged opposite to the first connecting rods 13, and each sliding rod 14 is slidably connected to the corresponding second connecting rod 112. With this setting method, when the first mounting rod 11 moves relative to the main body member 21 along the first direction X, the second connecting rod 112 can slide relative to the sliding rod 14, which helps to further adjust the distance between the first mounting rod 11 and the adjusting assembly 2 along the first direction X when the second mounting rod 12 is adjusted to the limit position relative to the adjusting assembly 2 along the first direction X. Furthermore, it helps to further adjust the distance between the first mounting rod 11 and the second mounting rod 12 along the first direction X, thereby helping to increase the overall length adjustment range of the bed frame 100 to better meet the different needs of users.

[0080] It can be understood that the second connecting rod 112 is arranged opposite to the first connecting rod 13, including that the second connecting rod 112 abuts against the first connecting rod 13, or the second connecting rod 112 is spaced apart from the first connecting rod 13.

[0081] Optionally, please continue to refer toFigure 1 and Figure 2 Along the first direction X, a first space 3 is formed between the second mounting rod 12 and one of the first mounting rods 11, and a second space 4 is formed between the second mounting rod 12 and the other first mounting rod 11. The above-mentioned adjusting assembly 2 is provided in both the first space 3 and the second space 4, so that any one of the first mounting rods 11 can move relative to the second mounting rod 12 along the first direction X. By providing the adjusting assembly 2 on both sides of the second mounting rod 12, both of the first mounting rods 11 can be adjusted along the first direction X. On the one hand, it helps to improve the flexibility of the overall length adjustment of the bed frame 100, and on the other hand, it helps to further expand the adjustment range of the length of the bed frame 100 to meet various needs of users.

[0082] In some embodiments, please refer to Figure 1 and Figure 2 The adjusting assemblies 2 in the above-mentioned first space 3 and second space 4 are provided in plurality, and the plurality of adjusting assemblies 2 located in the same space are arranged at intervals along the second direction Y. By arranging a plurality of adjusting assemblies 2 at intervals in the same space, compared with only providing one adjusting assembly 2, it helps to improve the supporting effect in the first space 3 and the second space 4, and avoid a large gap between the first mounting rod 11 and the second mounting rod 12 after adjusting the first mounting rod 11, thereby causing the supporting effect to decline.

[0083] In addition, by providing a plurality of adjusting assemblies 2, the volume of a single adjusting assembly 2 can also be reduced, and the situation that the installation and transportation of the bed frame 100 are inconvenient due to the setting of a large-volume adjusting assembly 2 can be avoided.

[0084] Optionally, please continue to refer to Figure 1 and Figure 2 The bed frame 100 further includes a limiting assembly 5. A first limiting hole 25 is provided on the adjusting assembly 2 along the second direction Y, and a second limiting hole 141 corresponding to the first limiting hole 25 is provided on the sliding rod 14 along the second direction Y. The limiting assembly 5 penetrates through the first limiting hole 25 and the second limiting hole 141 along the second direction Y to limit the positions of the adjusting assembly 2 and the sliding rod 14 in the first direction X. By providing the limiting assembly 5 and penetrating it through the adjusting assembly 2 and the sliding rod 14, it helps to connect the adjusting assembly 2 and the sliding rod 14, so that when adjusting the adjusting assembly 2 to make the first mounting rod 11 and the second mounting rod 12 move relative to the adjusting assembly 2 along the first direction X, the sliding rod 14 can be driven to slide along the first connecting rod 13 and the second connecting rod 112, which helps to improve the rationality of the structure of the bed frame 100. On the other hand, the limiting assembly 5 also limits the positions of the plurality of adjusting assemblies 2 in the first direction X, which helps to facilitate the unified position adjustment of the plurality of adjusting assemblies 2 by the user, and further helps to avoid the dislocation of the plurality of adjusting assemblies 2.

[0085] Optionally, please refer to Figure 1 and Figure 2 , the above-mentioned limit component 5 includes a limit rod 51 and two locking members 52. The limit rod 51 is inserted through the above-mentioned first limit hole 25 and the second limit hole 141 along the second direction Y. The two locking members 52 are movably connected to both ends of the limit rod 51, and the locking member 52 is located outside the second limit hole 141. The locking member 52 is configured to be able to abut against the outer surface of the sliding rod 14 to prevent the above-mentioned limit rod 51 from detaching from the second limit hole 141. By providing the limit rod 51 and the locking members 52 on both sides that can abut against the outer surface of the sliding rod 14, it helps to facilitate the installation of the limit rod 51 by the user. It only needs to make the locking members 52 and the limit rod 51 pass through the first limit hole 25 and the second limit hole 141, and then rotate the locking members 52 on both sides to lock the position of the limit component 5, thereby helping to improve the installation convenience of the limit component 5.

[0086] It can be understood that the above-mentioned locking member 52 is generally in a long strip shape. The width of the locking member 52 is smaller than the sizes of the first limit hole 25 and the second limit hole 141, and at the same time the length of the locking member 52 is larger than the sizes of the first limit hole 25 and the second limit hole 141. This setting method helps the locking member 52 to be inserted through the first limit hole 25 and the second limit hole 141 along its own width direction and can abut against the outer surface of the sliding rod 14 along its own length direction, which helps to limit the position of the limit rod 51 along the second direction Y.

[0087] It can be understood that the above-mentioned limit rod 51 and the two locking members 52 can be but are not limited to the above-mentioned movably connected form, and can also be other forms such as threaded connection. Taking the threaded connection as an example, at this time the two locking members 52 are two nuts. The projection dimension of the nut along the second direction Y is larger than the opening dimension of the second limit hole 141. Threads are provided at both ends of the limit rod 51. After the limit rod 51 passes through the second limit hole 141, the nut abuts against the outer surface of the sliding rod 14 through threaded connection. This embodiment does not make specific limitations on this.

By providing at least two first support rods 6 located at both ends of the second mounting rod 12, it helps to improve the support for the second mounting rod 12 and also helps to keep the second mounting rod 12 stable.

[0089] In another example, the bed frame 100 further includes a second support rod 7. One end of the second support rod 7 is connected to the first mounting rod 11, and the other end of the second support rod 7 is configured to support on the ground to support the first mounting rod 11, which helps to improve the support for the first mounting rod 11 and also helps to keep the first mounting rod 11 stable.

[0090] In yet another example, the bed frame includes at least two first support rods 6 and a second support rod 7. The two first support rods 6 are respectively located at both ends of the second mounting rod 12, and one end of the first support rod 6 is connected to the second mounting rod 12, and the other end of the first support rod 6 is configured to support on the ground to support the second mounting rod 12. One end of the second support rod 7 is connected to the first mounting rod 11, and the other end of the second support rod 7 is configured to support on the ground to support the first mounting rod 11. By providing the first mounting rod 11 and the second mounting rod 12, it helps to improve the support for the entire bed frame 100 and also helps to keep the entire bed frame 100 stable.

[0091] In some embodiments, please refer to Figure 3 , when the bed frame 100 includes the first support rod 6, one end of the first support rod 6 is also connected to the part of the first connecting rod 13 passing through the second mounting rod 12. This setting method helps the first support rod 6 to provide a certain supporting force for the first connecting rod 13, and further helps to make the connection between the first connecting rod 13 and the second mounting rod 12 more stable.

[0092] Please refer to Figure 3, both ends of the second mounting rod 12 are provided with first mounting holes 122 penetrating along the first direction X, and the bottom of the second mounting rod 12 is provided with second mounting holes 123 communicating with the first mounting holes 122. One end of the first support rod 6 extends into the first mounting hole 122 from the second mounting hole 123, and a groove portion 61 is provided at one end of the first support rod 6. The groove portion 61 is located in the first mounting hole 122. The first connecting rod 13 passes through the groove portion 61 and the first mounting hole 122 to connect the first support rod 6, the first connecting rod 13 and the second mounting rod 12. This setting method enables the first support rod 6, the first connecting rod 13 and the second mounting rod 12 to be fixedly connected without additionally arranging connecting parts, and the fixed connection of the three can be realized through mortise and tenon connection, which helps to improve the convenience of the user for assembling and disassembling the bed frame 100.

[0093] It can be understood that the materials of the above-mentioned first mounting rod 11, second mounting rod 12, first connecting rod 13, second connecting rod 112, first support rod 6 and second support rod 7 are preferably wood. The wood material has high stability, which helps to improve the service life of the first mounting rod 11, second mounting rod 12, first connecting rod 13 and sliding rod 14. At the same time, using the wood material, the bed frame 100 can be fixed by mortise and tenon connection without additionally arranging a variety of connecting parts, which helps to improve the convenience of the user for assembling and disassembling the bed frame 100.

[0094] In some embodiments, please refer to Figure 4 , the upper surface of the first mounting rod 11 is provided with a plurality of third mounting holes 113, and the plurality of third mounting holes 113 are arranged at intervals along the second direction Y. The third mounting holes 113 are configured to connect the headboard or the footboard. By providing the third mounting holes 113 on the surface of the first mounting rod 11, it helps to meet the various needs of users and enables them to choose whether to connect the headboard or the footboard by themselves.

[0095] The following briefly describes the process of adjusting the length of the bed frame 100 of the adjustable-length bed frame 100 of the present application:

[0096] In one way, the knob 24 on the second adjusting member 23 located in the hollow part of the plurality of adjusting assemblies 2 can be rotated. The rotation of the second adjusting member 23 drives the adjusting assembly 2 to move along the first direction X, and the adjusting assembly 2 can be moved relative to the second mounting rod 12 along the first direction X. At the same time, because the adjusting assembly 2 is also connected to the first mounting rod 11, when the adjusting assembly 2 moves relative to the second mounting rod 12 along the first direction X, the adjusting assembly 2 can simultaneously drive the first mounting rod 11 to move synchronously along the first direction X to adjust the distance between the first mounting rod 11 and the second mounting rod 12. At the same time, the adjusting assembly 2 drives the sliding rod 14 to slide along the first connecting rod 13 through the limiting assembly 5.

[0097] In another way, the knob 24 on the first adjusting member 22 located in the hollow parts of the plurality of adjusting assemblies 2 can also be rotated, and the rotation of the first adjusting member 22 drives the first mounting rod 11 to move along the first direction X. At the same time, since the adjusting assembly 2 is also connected to the second mounting rod 12, when the first mounting rod 11 moves relative to the adjusting assembly 2 along the first direction X, the distance between the first mounting rod 11 and the second mounting rod 12 can be adjusted. At the same time, the adjusting assembly 2 drives the sliding rod 14 to slide along the second connecting rod 112 through the limiting assembly 5.

[0098] It can be seen that the adjustable-length bed frame of the present application can adjust the position of the second mounting rod 12 on only one side of the first mounting rod 11, or can adjust the positions of the second mounting rods 12 on both sides at the same time, with a wider applicability.

[0099] Please refer to Figure 5 , Figure 5 which is a schematic structural diagram of another adjustable-length bed frame disclosed in the embodiment of the present application. Second, the present application also discloses another adjustable-length bed frame 100, including a bed frame main body 1 and an adjusting assembly 2.

The two second connecting rods 112 are located at both ends of the first mounting rod 11 along the second direction Y, and the two second connecting rods 112 are connected to the opposite ends of one first mounting rod 11 and the other first mounting rod 11. A sliding rod 14 is sleeved on the second connecting rod 112. The sliding rod 14 extends along the first direction X, and the sliding rod 14 is connected to the other first mounting rod 11. The sliding rod 14 is slidable relative to one of the second connecting rods 112 along the first direction X. The adjusting assembly 2 is located between the two first mounting rods 11. The adjusting assembly 2 is connected to one of the first mounting rods 11. The adjusting assembly 2 is connected to the sliding rod 14. The adjusting assembly 2 is configured to make one of the first mounting rods 11 movable relative to the other first mounting rod 11 along the first direction X to adjust the distance between one of the first mounting rods 11 and the other first mounting rod 11 in the first direction X. Wherein, the second direction Y intersects with the first direction X.

[0100] By arranging the first mounting rods 11 facing each other along the first direction X and spaced apart, and the adjusting assembly 2 is located between the two first mounting rods 11. The adjusting assembly 2 is connected to the first mounting rods 11 and is configured to move one of the first mounting rods 11 relative to the other first mounting rod 11 along the first direction X, so as to adjust the distance between one of the first mounting rods 11 and the other first mounting rod 11 in the first direction X. This setting method helps to flexibly adjust the distance between the two first mounting rods 11 through the adjusting assembly 2, and further helps to be able to flexibly adjust the overall length of the bed frame 100 according to different requirements of the user for the length of the bed frame 100.

[0101] In addition, by arranging the adjusting device between the two first mounting rods 11, it helps to not affect the internal support of the bed frame 100 when adjusting the distance between the two first mounting rods 11.

[0102] In addition, the adjusting assembly 2 is also connected to the sliding rod 14, and the sliding rod 14 is slidably connected to the second connecting rod 112. When flexibly adjusting the distance between the two first mounting rods 11 through the adjusting assembly 2, it helps the sliding rod 14 to slide along the second connecting rod 112, and further helps to not affect the overall support of the bed frame body 1.

In the third aspect, the present application also discloses a bed, including the adjustable-length bed frame 100 in the first aspect or the second aspect above. A mattress can be arranged on the bed frame 100, so that the bed frame can support the mattress, and at the same time, a headboard or a footboard can be connected to the two first mounting rods 11 of the bed frame 100.

[0106] Among them, the bed frame 100 in the embodiment of the present application can have the same structure as any one of the bed frames 100 in the above embodiments and can bring the same or similar beneficial effects. Specifically, reference can be made to the description in the above embodiments, and the embodiments of the present application will not be elaborated here.
