[0081] Example 1

[0082] This embodiment provides a bed, which includes a mattress and a bed frame. The bed frame is used to support the mattress and provide good support for the mattress.

[0083] The existing bed frame has only one height position when in use, but different users have different requirements for the height of the mattress. The bed frame with a fixed height is difficult to meet the diverse usage needs of users.

[0084] In order to solve this problem, this embodiment provides a bed frame, such as Figure 1-Figure 2 As shown, the bed frame includes a first frame 200, a second frame 300, and a bed frame adjustment structure 100. One end of the bed frame adjustment structure 100 is connected to the first frame 200, and the other end is connected to the second frame 300. The bed frame adjustment structure 100 serves as an intermediate connection between the first frame 200 and the second frame 300, ensuring the stability of the connection between the first frame 200 and the second frame 300 and providing good support. The bed frame adjustment structure 100 can also adjust the distance between the first frame 200 and the second frame 300, thereby adjusting the overall height of the bed frame to meet the height requirements of different users.

[0085] For example, children or the elderly can choose a lower height when using it to avoid serious injuries when accidentally falling, thereby improving safety; young people can choose a lower height when using it to experience Japanese tatami, or choose different bed frame heights according to different scenarios such as watching movies and reading.

[0086] Specifically, if Figure 1-Figure 2As shown, the bed frame adjustment structure 100 includes a first support member 1 and a second support member 2. The first support member 1 is connected to the first frame 200, and the second support member 2 is connected to the second frame 300 of the bed frame. The first support member 1 and the second support member 2 jointly realize the support between the first frame 200 and the second frame 300.

[0087] If the two supporting parts are an inner tube and an outer tube respectively, the inner tube and the outer tube are sleeved on each other and fixed by a fixing pin, with this structure, when locking and unlocking, the fixing pin needs to be frequently disassembled. The locking and unlocking process is cumbersome, time-consuming and labor-intensive, and inconvenient to operate, which makes it difficult to meet the user's usage needs.

[0088] For this reason, Figure 1-Figure 2 As shown, the bed frame adjustment structure 100 provided in this embodiment further includes a locking assembly 3. One of the first support member 1 and the second support member 2 is provided with a slideway 21, and the other is provided with a fixing hole 11. The locking assembly 3 is provided along the axial direction of the locking assembly 3 and penetrates the slideway 21 and the fixing hole 11. The locking assembly 3 is configured to be pressed along the axial direction of the locking assembly 3 so that the locking assembly 3 slides along the slideway 21, and the second support member 2 and the first support member 1 can slide relative to each other, thereby adjusting the distance between the first frame 200 and the second frame 300.

[0089] Since one of the first support member 1 and the second support member 2 is provided with a slideway 21, and the other is provided with a fixing hole 11, as shown in FIG. Figure 1-Figure 2 As shown, the locking assembly 3 is provided through the slide 21 and the fixing hole 11, and the locking assembly 3 is used to realize the connection between the first support member 1 and the second support member 2. The locking assembly 3 is fixed relative to the fixing hole 11. When the locking assembly 3 is in a locked state, the first support member 1 and the second support member 2 cannot move relative to each other, and the first frame 200 and the second frame 300 correspond to a first height distance. After pressing the locking assembly 3 in the axial direction of the locking assembly 3, the locking assembly 3 can slide along the slide 21. The slide 21 plays a guiding and path planning role for the locking assembly 3. When the locking assembly 3 is in an unlocked state, the first support member 1 and the second support member 2 can slide relative to each other. As the first support member 1 and the second support member 2 extend or shorten, the relative position of the first frame 200 and the second frame 300 will also change. At this time, the first frame 200 and the second frame 300 correspond to a second height distance.

[0090] Therefore, under the adjustment action of the bed frame adjustment structure 100 , a first height distance and a second height distance may be provided between the first frame 200 and the second frame 300 , thereby achieving height adjustment between the first frame 200 and the second frame 300 .

[0091] Furthermore, simply pressing the locking assembly 3 can unlock and lock the locking assembly 3, which is simple to operate, simplifies the user experience, saves time and effort, and improves user satisfaction. The pressing direction of the locking assembly 3 is the same as the threading direction of the locking assembly 3, which is more in line with the user's operating habits and further improves ease of use. The pressing force on the locking assembly 3 can be directly converted into the unlocking driving force of the locking assembly 3, without the need for intermediate force transmission components or changes in force transmission direction. The unlocking process responds quickly and is highly reliable.

[0092] The axial direction of the locking assembly 3 is the first direction, which can be identified by D1; the extension direction of the slide 21 is the second direction, which can be identified by D2; the width direction of the slide 21 is the third direction, which can be identified by D3. The axial direction of the locking assembly 3, the extension direction of the slide 21, and the width direction of the slide 21 are perpendicular to each other. These three directions only represent spatial directions and have no substantive meaning. It is understandable that if the first support member 1 and the second support member 2 rotate, the positions of the slide 21 and the locking assembly 3 provided on the support members will also change in three-dimensional space. Although these three directions will also change, the perpendicular relationship between the three directions will not change.

[0093] In one embodiment, Figures 1-4 As shown, the first support member 1 is rotatably connected to the first frame 200 , and the second support member 2 is rotatably connected to the second frame 300 , for folding and unfolding between the first frame 200 and the second frame 300 .

[0094] That is, the two ends of the bed frame adjustment structure 100 are respectively connected to the first frame 200 and the second frame 300, so the connection between the first frame 200 and the second frame 300 is not a rigid connection, but a relatively movable arrangement. If the first frame 200 and the second frame 300 are rotated toward each other through the bed frame adjustment structure 100, the first frame 200 and the second frame 300 are moved closer to each other, realizing a folded state of the bed frame, saving space when not in use; if the first frame 200 and the second frame 300 are rotated away from each other through the bed frame adjustment structure 100, the first frame 200 and the second frame 300 are separated from each other, realizing an unfolded state of the bed frame, improving user comfort and experience.

[0095] When switching between the folded state and the unfolded state, the relative positions of the first frame 200 and the second frame 300 connected to the two support members will change. The first support member 1 is rotated to be connected to the first frame 200, and the second support member 2 is rotated to be connected to the second frame 300. As the first support member 1 extends or contracts relative to the second support member 2, it is used to compensate for the height position change.

[0096] In one embodiment, Figures 1-4As shown, the first frame 200 includes a first transition portion 201 and two first sub-frames 202. The two first sub-frames 202 are arranged opposite each other, and the two ends of the first transition portion 201 are respectively rotatably connected to the two first sub-frames 202. The first transition portion 201 is used to allow the two first sub-frames 202 to rotate toward or away from each other, further realizing the expansion and folding of the first frame 200.

[0097] The second frame 300 includes a second transition portion 301 and two second sub-frames 302. The two second sub-frames 302 are arranged opposite each other, and the two ends of the second transition portion 301 are respectively rotatably connected to the two second sub-frames 302. The second transition portion 301 allows the two second sub-frames 302 to rotate toward or away from each other, further realizing the expansion and folding of the second frame 300.

[0098] The first turning portion 201 and the second turning portion 301 are correspondingly arranged, and the length of the first turning portion 201 is different from the length of the second turning portion 301 .

[0099] For example, the length of the first turning portion 201 is greater than the length of the second turning portion 301. In the folded state, the first turning portion 201 and the two first sub-frames 202 form a U-shaped space, and the second turning portion 301 and the two second sub-frames 302 form a U-shaped structure. The two U-shaped spaces can accommodate the U-shaped structure, and the first frame 200 and the second frame 300 can be rotated synchronously for folding, and the first frame 200 can at least partially cover the second frame 300, so that the floor area can be reduced by approximately half.

[0100] It should be noted that the bed frame provided by the present invention has multiple usage states. When the user needs to use it, the bed frame is in an unfolded state, which is convenient for placing the mattress on the bed frame. The unfolded state is further divided into two forms, namely, based on the user's usage needs, on the basis of the unfolded state, there is a first height distance or a second height distance between the first frame 200 and the second frame 300; when the user does not need to use it, the bed frame is in a folded state, wherein the folded state is specifically divided into two folding forms. In the first folded state, the first frame 200 and the second frame 300 are rotated toward each other through the bed frame adjustment structure 100, so that the first frame 200 and the second frame 300 are approximately fitted together, which is used to reduce the space height; in the second folded state, on the basis of the first folded state, under the rotation action of the first turning part 201 and the second turning part 301, the two first sub-frames 202 of the first frame 200 are rotated toward each other, and the two second sub-frames 302 of the second frame 300 are rotated toward each other, which is used to reduce the occupied area.

[0101] It can be understood that the present disclosure provides at least the above four usage states, and there are many usage modes. Users can freely choose according to actual usage needs, which is highly flexible and can be used to meet the diverse usage needs of users.

[0102] In one embodiment, Figure 5 As shown, the first support member 1 and the second support member 2 extend along the second direction, and both are specifically long rod-shaped structures. The lengths of the first support member 1 and the second support member 2 along the second direction can be approximately the same, and the widths of the first support member 1 and the second support member 2 along the third direction can be approximately the same, so that in the folded state, the first support member 1 and the second support member 2 overlap with each other after being shortened, saving space.

[0103] In one embodiment, at least one end of the first support member 1 and the second support member 2 along the second direction may be an arc structure to prevent the user from being scratched by sharp corners during operation.

[0104] When the bed frame is in the second folding state, the first frame 200 and the second frame 300 are in an upper and lower superimposed state. If the first support rod and the second support rod 2 are both straight rod structures, since the two ends of the bed frame adjustment structure 100 are respectively rotatably connected to the first frame 200 and the second frame 300, the rotation connection positions at both ends of the bed frame adjustment structure 100 are also set up and down, resulting in the bed frame adjustment structure 100 not being parallel to the first frame 200 or the second frame 300, but the bed frame adjustment structure 100 is tilted relative to the outer frame of the first frame 200 or the second frame 300 and is in a tilted state, resulting in interference between the bed frame adjustment structure 100 and the first frame 200 or the second frame 300.

[0105] To solve this problem, Figure 5 As shown, one of the first support member 1 and the second support member 2 provided by the present disclosure is an L-shaped structure.

[0106] Since the two ends of the L-shaped structure are not collinear but have a certain height distance, the height distance can correspond to the rotation connection positions set up above and below the first frame 200 and the second frame 300. In the second folded state, the bed frame adjustment structure 100 will not be tilted, reducing the risk of position interference between the bed frame adjustment structure 100 and the first frame 200 or the second frame 300 when folding.

[0107] Specifically, the first support member 1 includes a first horizontal portion 12 and a first vertical portion 13. One end of the first horizontal portion 12 is rotatably connected to the first frame 200, and the other end is connected to the first vertical portion 13 and is vertically arranged relative to the first vertical portion 13. The first vertical portion 13 is slidably matched with the second support member 2, and the slide 21 or the fixing hole 11 is arranged on the first vertical portion 13.

[0108] In this way, in the unfolded state, the first vertical portion 13 of the first support member 1 and the second support member 2 are both in a vertical state, which provides a good supporting effect; in the folded state, since the first horizontal portion 12 is actually formed by extending the first vertical portion 13 upward or downward, the first horizontal portion 12 is used to make up for the height distance between the first frame 200 or the second frame 300, so that the first vertical portion 13 of the first support member 1, the second support member 2 and the outer frame of the first frame 200 or the second frame 300 are arranged in parallel, reducing interference during folding.

[0109] In one embodiment, Figure 2 and Figure 5 As shown, along the extension direction of the slideway 21, the width of the first horizontal portion 12 is less than or equal to the width of the first frame 200. With this arrangement, when deployed, the first horizontal portion 12 is horizontal, and the upper and lower edges of the first horizontal portion 12 do not extend beyond the outer edges of the first frame 200, preventing the first horizontal portion 12 from being exposed or protruding. The first horizontal portion 12 is essentially hidden, improving aesthetics and enhancing comfort and safety in use or operation.

[0110] In one embodiment, Figure 4 and Figure 5 As shown, along the width direction of the slideway 21, the length of the first horizontal portion 12 is less than or equal to the sum of the widths of the first frame 200 and the second frame 300. With this arrangement, when folded, the first horizontal portion 12 is upright. Even if the first frame 200 and the second frame 300 are closely aligned or have a very small gap between them, the upper and lower ends of the first horizontal portion 12 will not extend beyond the outer edges of the first frame 200 and the second frame 300. This prevents the first horizontal portion 12 from being exposed or protruding, improves aesthetics, and enhances comfort and safety during use or operation.

[0111] In one embodiment, the second support member 2 includes a second horizontal portion (not shown in the figure) and a second vertical portion (not shown in the figure), one end of the second horizontal portion is rotatably connected to the second frame 300, and the other end is connected to the second vertical portion and is vertically arranged relative to the second vertical portion, the second vertical portion is slidably matched with the first support member 1, and the slide 21 or the fixing hole 11 is arranged on the second vertical portion.

[0112] In this way, in the unfolded state, the second vertical portion of the second support member 2 and the first support member 1 are both in a vertical state, which provides a good supporting effect; in the folded state, since the second horizontal portion is formed by extending upward or downward through the second vertical portion, the second horizontal portion is used to make up for the height distance between the first frame 200 or the second frame 300, so that the second vertical portion of the second support member 2, the first support member 1 and the outer frame of the first frame 200 or the second frame 300 are arranged in parallel, reducing interference during folding.

[0113] In one embodiment, the width of the second horizontal portion along the extension direction of the slide 21 is less than or equal to the width of the second frame 300. With this arrangement, when deployed, the second horizontal portion is horizontal, and the upper and lower side edges of the second horizontal portion do not extend beyond the outer edges of the second frame 300, preventing the second horizontal portion from being exposed or protruding. The second horizontal portion essentially serves to conceal the second horizontal portion, improving aesthetics and enhancing comfort and safety in use or operation.

[0114] In one embodiment, the length of the second horizontal portion along the width of the slide 21 is less than or equal to the sum of the widths of the first frame 200 and the second frame 300. With this arrangement, when folded, the second horizontal portion is upright. Even if the first frame 200 and the second frame 300 are closely aligned or have a very small gap between them, the upper and lower ends of the second horizontal portion will not extend beyond the outer edges of the first and second frames 200 and 300, preventing the second horizontal portion from being exposed or protruding. This improves aesthetics and enhances comfort and safety during use or operation.

[0115] In one embodiment, Figure 5 As shown, at least one of the first support member 1 and the second support member 2 is provided with a limiting portion 4 , and the limiting portion 4 is used for limiting the position between the first support member 1 and the second support member 2 .

[0116] For example, the limiting portion 4 is provided on the first support member 1, and the limiting portion 4 can limit the relative positions of the two support members. When the first support member 1 and the second support member 2 slide relative to each other, the limiting portion 4 can prevent the first support member 1 and the second support member 2 from being offset in position due to rotation, so that the two can be kept in the same straight line as much as possible during the extension or contraction process along the second direction.

[0117] The edge of the limiting portion 4 is rounded, and the connection position between the limiting portion 4 and the first support member 1 is transitioned through an arc to reduce the risk of scratches to the user during use.

[0118] In one embodiment, the stopper 4 corresponding to the first support member 1 is integrally formed with the first support member 1, thereby reducing the number of assembly steps required for the first support member 1 and the stopper 4 and saving production costs. Specifically, during actual production, the first support member 1 can be bent upward along its edge, which simplifies the process and reduces production costs.

[0119] In one embodiment, the limiting portion 4 extends along the extending direction of the slideway 21 .

[0120] That is, the limiting portion 4 extends along the second direction, the extending direction of the limiting portion 4 is the same as the sliding direction of the locking assembly 3, and the relative sliding direction of the first support member 1 and the second support member 2 is the same as the extending direction of the limiting portion 4. In this way, during the extension and contraction of the first support member 1 and the second support member 2, the locking member 31 can limit the first support member 1 and the second support member 2, thereby improving the limiting effect.

[0121] It can be understood that this embodiment does not limit the length of the limiting portion 4 along the second direction. The length of the limiting portion 4 can be relatively small, so that the limiting portion 4 is similar to a block-shaped structure. The length of the limiting portion 4 can also be relatively large. For example, the length of the limiting portion 4 is greater than or equal to the length of the slide 21, that is, the limiting range of the limiting portion 4 for the first support member 1 and the second support member 2 completely covers the telescopic range, further preventing the two supports from positionally offsetting during the mutual sliding process.

[0122] In one embodiment, the limiting portion 4 is provided on at least one side of the first support member 1 along the width direction of the slideway 21 .

[0123] For example, there is one limiting portion 4, one limiting portion 4 being provided on either side of the first support member 1 along the third direction. The first support member 1 and the limiting portion 4 form an L-shaped structure, which can achieve single-sided positioning of the two support members along the third direction. Alternatively, there are two limiting portions 4, two limiting portions 4 being provided on either side of the first support member 1 along the third direction, and two locking members 31 being provided in parallel and facing each other. In this case, the first support member 1 and the two limiting portions 4 form a U-shaped structure, which can achieve double-sided positioning of the two support members along the third direction. With this structure, during assembly, the second support member 2 is passed through the U-shaped structure from one end of the first support member 1 along the second direction. The two limiting portions 4 also serve to a certain extent as a guide during the installation or disassembly process.

[0124] It can be understood that the limiting portion 4 can be set not only on the first support member 1, but also on the second support member 2. The limiting portion 4 is set on at least one side of the second support member 2 along the width direction of the slide 21 to achieve unilateral or bilateral limitation of the first support member 1 and the second support member 2 in the third direction.

[0125] In one embodiment, a support portion (not shown) is provided at one end of the first support member 1 away from the second support member 2, and the support portion is used to support the first frame 200. Since the support portion is provided close to the first frame 200, when in the expanded state, the support portion can support and bear the weight of the first frame 200, thereby sharing a certain amount of pressure with the first support member 1 and improving the support stability and reliability of the bed frame in the expanded state.

[0126] Among them, along the axial direction of the locking assembly 3 , the supporting portion and the limiting portion 4 are arranged on both sides of the first support member 1 .

[0127] That is, the limiting portion 4 is folded inward along the edge of the first support member 1, and the supporting portion is folded outward along the edge of the first support member 1. While satisfying a good supporting effect, it will not interfere with the limiting and sliding process between the first support member 1 and the second support member 2.

[0128] In one embodiment, Figure 5 As shown, a positioning portion 7 is provided at one end of the second support member 2 away from the first support member 1. The positioning portion 7 is used to position the second support member 2 and the second frame 300. In the deployed state, the lower end of the positioning portion 7 can abut against the top surface of the second frame 300, providing support and improving the verticality of the second support member 2 in this state.

[0129] Among them, along the axial direction of the locking assembly 3 , the positioning portion 7 and the limiting portion 4 are arranged on both sides of the second support member 2 .

[0130] This is equivalent to folding the limiting portion 4 inward along the edge of the first support member 1, and the positioning portion 7 outward along the edge of the first support member 1. This provides good support without interfering with the limiting and sliding process between the first support member 1 and the second support member 2. Furthermore, if the second folding state is desired, the positioning portion 7 can prevent the bed frame from rotating in the opposite direction and causing collapse. Furthermore, in the second folding state, the positioning portion 7 can overlap the second frame 300, acting as a limiter for the second support member 2 and the second frame 300, reducing the risk of uncoupling and, to a certain extent, improving stability in this folded state.

[0131] In one embodiment, Figure 5-Figure 7 As shown, the slideway 21 includes a connecting slide groove 211 and a locking hole 212. The locking assembly 3 is inserted through the locking hole 212 and the fixing hole 11, and is in the locked state. The locking assembly 3 is inserted through the fixing hole 11 and the slide groove 211 and can slide with the slide groove 211, and is in the unlocked state. Because the locking hole 212 and the slideway 21 are interconnected, the locking assembly 3 can slide directly from the locking hole 212 into the slide groove 211, making the transition between the folded state and the unfolded state seamless and smooth.

[0132] In one embodiment, the locking hole 212 is disposed on at least one side of the sliding groove 211 along the extending direction of the slideway 21 .

[0133] For example, the locking hole 212 is arranged on the side of the slide groove 211 close to the second frame 300, that is, the locking hole 212 is located below the slide groove 211. When the first support member 1 and the second support member 2 move toward each other, the first support member 1 and the second support member 2 are shortened, and the locking assembly 3 is passed through the locking hole 212, which corresponds to the locking position in the expanded state and with a first height distance to ensure the stability of the first frame 200 and the second frame 300 at this position.

[0134] Of course, the locking hole 212 can also be set on the side of the slide groove 211 close to the first frame 200, that is, the locking hole 212 is located above the slide groove 211. When the first support member 1 and the second support member 2 move away from each other, the first support member 1 and the second support member 2 extend, and the locking assembly 3 is passed through the locking hole 212. At this time, it corresponds to the locking position in the expanded state and with the second height distance to ensure the stability of the first frame 200 and the second frame 300 in this position.

[0135] It can be understood that the number of locking holes 212 can be one, and the locking hole 212 is arranged at the end of the slide groove 211. Specifically, the locking hole 212 is arranged at the end of the slide groove 211 where the first support member 1 and the second support member 2 are close to each other, that is, when the first support member 1 and the second support member 2 move in the direction away from each other, the two support members are in an extended state. At this time, the corresponding two frames have a second height distance, that is, the maximum height. The maximum height position can be locked by using the locking assembly to improve the stability at the maximum height position, while the minimum height position does not need to be locked; of course, the number of locking holes 212 can also be two, and the two locking holes 212 are respectively arranged at both ends of the slide groove 211, so that the first support member 1 and the second support member 2 can ensure good position stability at different height distances.

[0136] In one embodiment, Figure 5-Figure 7 As shown, the locking holes 212 are symmetrically arranged relative to the axial direction of the sliding groove 211.

[0137] That is, the locking hole 212 is not eccentrically arranged relative to the slide groove 211, but the axis of the slide groove 211 passes through the center of the locking hole 212. The transition between the slide groove 211 and the locking hole 212 is smooth and without corners. During use, the user does not need to lift or press down the locking component 3 in the third direction. The locking component 3 can slide smoothly and smoothly between the locking hole 212 and the slide groove 211. It is easy to operate and use, and the risk of jamming during state switching is reduced.

[0138] In one embodiment, Figure 8As shown, the locking assembly 3 includes a locking member 31, and the locking member 31 includes a guide portion 311 and a locking portion 312. The guide portion 311 and the locking portion 312 are interconnected and coaxially arranged. The guide portion 311 can be inserted into the slide groove 211 and slidably cooperate with the slide groove 211. The locking portion 312 can be inserted into the locking hole 212 and the fixing hole 11.

[0139] Since the slide 21 includes two parts, the slide groove 211 and the locking hole 212, the guide part 311 and the locking part 312 of the locking member 31 correspond to these two parts respectively. When the bed frame is unfolded, folded or the height is adjusted, the guide part 311 of the locking member 31 can slide in the slide groove 211 until it reaches the locking hole 212. The guide part 311 and the locking part 312 are coaxially arranged. When the locking member 31 is pressed along the first direction, the locking part 312 will fall into the locking hole 212, completing the locking action. At this time, a stable support effect is formed between the first frame 200 and the second frame 300.

[0140] Among them, the first support member 1 and the locking member 31 are set at an angle. For example, the first support member 1 and the locking member 31 are perpendicular to each other, and the angle between them is 90°. Of course, the angle between the first support member 1 and the locking member 31 can also be an acute angle or an obtuse angle.

[0141] It is understood that the outer contours of the locking portion 312 and the locking hole 212 are compatible. For example, the locking portion 312 may be cylindrical and the locking hole 212 may be circular. Alternatively, the locking portion 312 may be rectangular and the locking hole 212 may be square. Of course, the locking portion 312 and the locking hole 212 may also have other structures and shapes. The outer contours of the chute 211 and the guide portion 311 are compatible. The guide portion 311 may be cylindrical and the chute 211 may be elongated. The ends of the chute 211 along the first direction are arc-shaped structures to match the guide portion 311.

[0142] In one embodiment, along the width direction of the slideway 21 , the width dimension of the locking hole 212 is greater than the width dimension of the slide groove 211 .

[0143] When the locking hole 212 is a circular hole, the slide 21 is composed of a strip-shaped slide groove 211 and a locking hole 212 whose diameter is greater than the width of the slide groove 211. The sizes of the guide portion 311 and the locking portion 312 of the locking member 31 are correspondingly distinguished. When the guide portion 311 and the locking portion 312 are both cylindrical structures, the diameter of the guide portion 311 is smaller than the diameter of the locking portion 312. The guide portion 311 can be called a small neck and the locking portion 312 can be called a large neck. The diameter of the guide portion 311 is slightly smaller than the width of the slide groove 211, so that the guide portion 311 can slide freely along the slide groove 211. The diameter of the locking portion 312 is slightly smaller than the diameter of the locking hole 212, and the locking portion 312 can be accommodated in the locking hole 212.

[0144] In one embodiment, Figure 5-Figure 8 As shown, along the width direction of the slideway 21 , the width dimension of the locking portion 312 is greater than the width dimension of the guide portion 311 .

[0145] In this manner, if the locking member 31 is not pressed in the first direction, the locking portion 312 can only be located in the locking hole 212, rather than moving into the slide groove 211. At this time, the locking member 31 is temporarily fixed relative to the locking hole 212, and the first support member 1 and the second support member 2 are also relatively fixed, ensuring a stable support function between the first frame 200 and the second frame 300. When the locking member 31 is pressed in the first direction, the locking portion 312 is released from the locking hole 212, and the guide portion 311 can slide from the locking hole 212 into the slide groove 211, completing the unlocking process.

[0146] In one embodiment, Figure 8 As shown, the locking member 31 further includes a stopper 313 , which is disposed on at least one of the sides where the guide portion 311 and the locking portion 312 are away from each other.

[0147] That is, the stop portion 313 is set on the outside of the guide portion 311 or the locking portion 312. Since the locking member 31 needs to be pressed along the first direction, the stop portion 313 can be used to prevent the locking member 31 from falling out of the slide 21, thereby achieving the limitation of the guide portion 311 and / or the locking portion 312.

[0148] In one embodiment, along the width direction of the slideway 21 , the width dimension of the stop portion 313 is greater than the width dimension of the locking hole 212 .

[0149] In this manner, the stopper 313 is relatively wide and located outside the guide portion 311 or the locking portion 312. This provides the user with a larger pressing area, making it easier for the user to press and unlock the lock. Furthermore, the larger stopper 313 will not enter the locking hole 212, making it easier for the user to press the stopper 313 again later.

[0150] It should be noted that if Figure 8 As shown, the locking member 31 can be composed of a screw and a T-nut. The T-nut has a large end and a small end. The threaded portion of the screw is threadedly connected to the small end of the T-nut. In this case, the threaded portion of the screw is the guide portion 311, and the small end of the T-nut is the locking portion 312. The large end of the T-nut and the nut of the screw are the stopper portion 313. Using this method to form the locking portion 312 has a simple structure and low production cost. During installation, the threaded portion of the screw can first be inserted into the locking hole 212 and the fixing hole 11, and then the threaded portion of the screw can be threadedly connected to the small end of the T-nut, which has the advantage of easy installation.

[0151] It should be noted that if Figure 9-10 As shown, the locking member 31 can be composed of a sleeve and a rivet. One end of the rivet is a stepped shaft with a large shaft and a small shaft. The large shaft is connected to the shank of the rivet through the small shaft. The other end of the rivet is riveted to the sleeve. In this case, the shank of the rivet serves as a guide portion 311, the small shaft of the stepped shaft serves as a locking portion 312, and the large shaft of the stepped shaft and the sleeve serve as a stop portion 313. During installation, the shank of the rivet can be first inserted into the locking hole 212 and the fixing hole 11, and then the rivet can be riveted to the sleeve. This simple structure is easy to install.

[0152] In one embodiment, Figure 5-Figure 9 As shown, the locking assembly 3 further includes a reset member 32 , which is sleeved on the outside of the locking member 31 and disposed between the first support member 1 and the stop portion 313 of the locking member 31 for resetting the locking member 31 .

[0153] By pressing the stopper 313 of the locking portion 312 with external force, the reset member 32 can optionally be a spring. The spring compresses and pushes the locking portion 312 away from the locking hole 212, and the first support member 1 and the second support member 2 slide toward each other and shorten, so that a first height distance exists between the first frame 200 and the second frame 300. The first support member 1 and the second support member 2 slide away from each other and extend. Since the compressed reset member 32 has an elastic force, under this elastic force, the locking portion 312 can enter the locking hole 212, completing the self-locking process. In this way, the bed frame is very easy to operate when folding and unfolding, and the pressing direction of the reset member 32 also makes the user's operation more smooth, which is convenient for the user to operate.

[0154] It should be noted that if Figure 5-Figure 7 As shown, the slide 21 is provided on the first support member 1, and the fixing hole 11 is provided on the second support member 2. Of course, the positions of the fixing hole 11 and the slide 21 can also be interchanged. For example, the first support member 1 is provided with the fixing hole 11, and the second support member 2 is provided with the slide 21. Only the locking position of extension or shortening is different. The specific structure and principle are similar, so they will not be described in detail.

[0155] Example 2

[0156] This embodiment is similar to the first embodiment, and the only difference is the detailed structure of the limiting portion 4.

[0157] like Figures 11-16 As shown, in the bed frame adjustment structure 100 provided in this embodiment, an extension portion 5 is provided on a side of the limiting portion 4 away from the first support member 1 and toward the slide 21 along the width direction of the slide 21 .

[0158] That is, the free end of the limiting portion 4 is bent inward to form an extension portion 5, and the limiting portion 4 and the extension portion 5 form an L-shaped structure. At this time, the limiting portion 4 is used to limit the first support member 1 and the second support member 2 along the third direction, and the extension portion 5 is used to limit the first support member 1 and the second support member 2 along the first direction, further improving the limiting effect between the two support members and preventing the two support members from being offset in position.

[0159] Example 3

[0160] This embodiment is similar to the first embodiment, and the only difference is the connection structure between the first support member 1 , the second support member 2 and the limiting portion 4 .

[0161] like Figure 17 As shown, the first support member 1 and the second support member 2 provided in this embodiment both have a limiting portion 4, and the limiting portion 4 of the first support member 1 and the limiting portion 4 of the second support member 2 close to each other contact and guide each other.

[0162] In this way, during the relative sliding of the first support member 1 and the second support member 2, the limiting parts 4 corresponding to the two support members contact each other, increasing the contact area of ​​the two support members during the sliding process, improving the guiding matching effect, and further improving the limiting effect, preventing the two support members from positional displacement.

[0163] The limiting portion 4 of the first support member 1 and the limiting portion 4 of the second support member 2 can be located on the same side of the first support member 1, so that the first support member 1 and the second support member 2 can contact each other. The distance between the inner walls of the two limiting portions 4 of the first support member 1 is slightly greater than the distance between the outer walls of the two limiting portions of the second support member 2, so that the second support member 2 and the first support member 1 can be nested with each other.

[0164] In some other embodiments, the limiting portion 4 of the first support member 1 and the limiting portion 4 of the second support member 2 can also be located on the same side of the first support member 1 and arranged opposite to each other along the first direction. Then, there is no contact between the first support member 1 and the second support member 2, but there is a certain gap between them. However, the limiting portions 4 of the two support members can be used for guidance.

[0165] Example 4

[0166] This embodiment is similar to the third embodiment, and the only difference is the connection structure between the first support member 1 , the second support member 2 and the limiting portion 4 .

[0167] like Figures 18-20As shown, the two limiting portions 4 of the first support member 1 provided in this embodiment are arranged in parallel and opposite to each other, and the two limiting portions 4 of the first support member 1 are connected by a first connecting portion 6, so that a first tubular structure is formed between the first support member 1, the two limiting portions 4 and the first connecting portion 6, and the second support member 2 is passed through the first tubular structure and slidably cooperates with it.

[0168] In this manner, the two limiting portions 4 are arranged in parallel and facing each other, and the first support member 1 and the first connecting portion 6 are arranged in parallel and facing each other. Then, the first support member 1, one of the limiting portions 4, the first connecting portion 6, and the other limiting portion 4 are connected end to end to form a first tubular structure. The cavity of the first tubular structure is used to accommodate the second support member 2. Because the first tubular structure is relatively closed, the first support member 1 and the second support member 2 can simultaneously achieve positional limitation along the first direction and the third direction.

[0169] In one embodiment, the two limiting portions 4 of the second support member 2 are arranged in parallel and opposite to each other, and the two limiting portions 4 of the second support member 2 are connected by a second connecting portion (not shown in the figure), so that a second tubular structure is formed between the second support member 2, the two limiting portions 4 and the second connecting portion, and the first support member 1 is passed through the second tubular structure and slidably cooperates with it.

[0170] In this manner, the two limiting portions 4 are arranged in parallel and facing each other, and the second support member 2 and the second connecting portion are arranged in parallel and facing each other. Then, the first support member 1, one of the limiting portions 4, the second connecting portion, and the other limiting portion 4 are connected end to end to form a second tubular structure. The cavity of the second tubular structure is used to accommodate the first support member 1. Because the second tubular structure is relatively closed, it can simultaneously achieve positional limitation between the first support member 1 and the second support member 2 along the first direction and the third direction.

[0171] Of course, in some other embodiments, the first tubular structure and the second tubular structure may be provided at the same time, and the two tubular structures are nested with each other to further increase the guiding contact area and the limiting effect.
