Description

Technical Field

[0001] The present disclosure relates to the technical field of furniture assembly, and in particular, to a bed frame connector and a bed frame having the same. Background Art

[0002] In order to improve the convenience of transportation, some bed frames adopt a detachable design. This design allows the bed frame to be disassembled into multiple parts, thereby reducing the volume and weight during transportation. These parts usually include a support beam and a plurality of support ribs. In order to connect the support beam and the support ribs, some support beams are provided with sinks, and the support ribs can be placed in the sinks and fixed to the support beam by screws. However, this installation method requires more parts, and the installation process is time-consuming and labor-intensive. In order to simplify the installation process, some bed frames include bed frame connectors, which are welded to the support beams, and the support ribs are connected to the support beams through connectors, thereby achieving the fixation of the two. However, this type of bed frame has the problem of large packaging volume, which is not conducive to transportation.

[0003] Therefore, there is a need to design a bed frame connector that is easy to install and transport. Summary of the invention

[0004] In view of this, the present disclosure provides a bed frame connector and a bed frame having the same, aiming to reduce the difficulty of installing the bed frame connector and reduce the packaging volume of the bed frame.

[0005] In a first aspect, the present disclosure provides a bed frame connector, which includes a base, a connector and a support portion. The connector includes a column and two action portions, the column protruding downward from the base, each action portion protruding outward from the outer circumference of the column, and the two action portions are opposite to each other across the column. The support portion is arranged on the upper side of the base and is provided with two receiving recesses, the two receiving recesses are arranged along a first direction perpendicular to the up-down direction, and the upper side and the outer side of each receiving recess in the first direction are open.

[0006] The top wall of the support beam is provided with a connection hole, and the connection part can pass through the connection hole. The base and the action part are separated in the up and down direction, so after the connection part passes through the connection hole and rotates a certain angle, the top wall of the support beam is located between the base and the action part. When the bed frame connection piece has a tendency to deviate or escape from the connection hole, the top wall of the support beam can suppress this tendency, so that the bed frame connection piece maintains a connection relationship with the support beam. One end of the support rib can be installed on the bed frame connection piece through the receiving recess and supported by the support part. According to an embodiment of the present disclosure, the bed frame connection piece can be connected to the support beam through the connection part, and the support part of the bed frame connection piece can provide support for the support rib, so no additional installation tools are required when connecting the support rib and the support beam, and this implementation method can save installation time and reduce installation difficulty. In addition, since the bed frame connection piece does not rely on the existence of the support beam, this implementation method can also reduce the packaging volume and reduce transportation costs.

[0007] As a possible implementation, the bed frame connecting piece further includes two pressing bosses, which protrude downward from the base and are opposite to each other across the connecting portion.

[0008] Since the clamping boss protrudes downward from the base, the clamping boss can press against the top wall of the support beam, so that the bed frame connecting piece as a whole has a downward movement trend, thereby enhancing the connection stability between the bed frame connecting piece and the support beam. In addition, since the two clamping bosses are arranged opposite to each other across the connecting portion, uniform force distribution can be ensured.

[0009] As a possible implementation manner, the lower end surface of each clamping boss is provided with a first positioning protrusion protruding downward.

[0010] Two first positioning recesses are also provided on the top wall of the support beam. When the bed frame connector is installed at the target position, the first positioning protrusion will be located in a corresponding first positioning recess. At this time, if the bed frame connector moves in a direction away from the target position on a plane perpendicular to the up and down direction, the first positioning recess can limit the displacement of the first positioning protrusion in this direction to ensure that the bed frame connector is fixed at the target position in the support beam.

[0011] As a possible implementation manner, the base is provided with two through slots corresponding to the two pressing bosses respectively, and each through slot penetrates the base and partially surrounds a corresponding pressing boss.

[0012] According to the implementation of the present disclosure, the through slot can increase the elasticity of the clamping boss, making it easy to yield and deform after being subjected to force. In this way, when the bed frame connector is installed to the target position, the clamping boss can deform upward, so that after passing over the support beam, it contacts the top wall of the support beam and presses against the top wall of the support beam.

[0013] As a possible implementation, the base includes two ends extending along the second direction, each clamping boss is connected to a corresponding end, and a through narrow groove surrounds one side of the clamping boss close to the connecting portion, wherein the second direction is perpendicular to the first direction and the up and down directions.

[0014] If the through slot surrounds the side of the clamping boss close to the end, the structural strength of the end will be weakened, so that the end is easily damaged when subjected to external force. According to the implementation of the present disclosure, the through slot is located on the inner large surface of the base, so the structural strength of the base can be weakened to a lesser extent. In this way, the through slot can increase the elasticity of the clamping boss, making it easy to yield and deform after being subjected to force, while not weakening the structural strength of the base too much.

[0015] As a possible implementation manner, in the second direction, as they are away from the connecting portion, the first positioning protrusion and the end portion are arranged in sequence and spaced apart from each other.

[0016] In the process of installing the bed frame connector to the target position, the clamping boss contacts the top wall of the support beam after passing over it. Since the lower end surface of the first positioning protrusion is lower than the lower end surface of the clamping boss, the clamping boss will continue to move upward so that the first positioning protrusion contacts the top wall of the support beam until the first positioning protrusion moves into the corresponding first positioning recess. In the implementation of the present disclosure, the first positioning protrusion is spaced from the end in the second direction, and the end is the edge of the base. Therefore, when the bed frame connector rotates around the connecting portion, in the process of installing the bed frame connector to the target position, the first positioning protrusion can have a shorter rotation radius, thereby shortening the stroke of friction with the top wall of the support beam, so that the installation operation can be completed more easily. In addition, when the clamping boss yields and deforms under force, the part close to the end will be limited by the end, while the part away from the end can obtain a larger deformation amount. The first positioning protrusion is designed to be spaced relative to the end, so that the part of the clamping boss where the first positioning protrusion is located can be easily yielded and deformed, thereby passing over the support beam and continuing to move to the target position.

[0017] As a possible implementation manner, the two acting portions are arranged at intervals along the first direction, and the two pressing bosses are arranged at intervals along the second direction.

[0018] The space for the two action parts to rotate needs to be located inside the support beam, so the distance between the two action parts is configured to be smaller, which is beneficial to reducing the size of the support beam. In addition, the arrangement direction of the two action parts is perpendicular to the arrangement direction of the two pressing bosses, which can press the support beam in two perpendicular directions of the support beam, thereby enhancing the reliability of the connection between the bed frame connecting piece and the support beam.

[0019] As a possible implementation method, the two acting parts are opposite to each other along the first direction separated by the column part, and two clamping protrusion groups are provided on the lower end surface of the base. The two clamping protrusion groups are opposite to each other along the first direction separated by the connecting part, and each clamping protrusion group includes multiple clamping protrusions, and the multiple clamping protrusions are basically arranged at intervals along a second direction perpendicular to the first direction and the up and down directions.

[0020] After the support ribs are connected to the support beams, on either side of the column along the first direction, from top to bottom, there are the support ribs, the base, the support beam, and the action portion. In this way, the pressure exerted by the support ribs on the base can be transmitted downward, so that the gap between the base and the action portion is reduced, thereby clamping the support beam, which helps to improve the stability of the connection between the bed frame connecting piece and the support beam. In addition, the clamping protrusions can further reduce the gap between the base and the action portion, so that after the bed frame connecting piece is connected to the support beam, the base and the action portion can clamp the top wall of the support beam, which helps to improve the stability of the connection.

[0021] As a possible implementation manner, a second positioning protrusion is provided on the bottom wall of each receiving recess.

[0022] A second positioning recess is provided at the bottom of the support rib. When the support rib is installed in the receiving recess, the second positioning protrusion is located in the second positioning recess, thereby limiting the displacement of the support rib on a plane perpendicular to the up and down directions and fixing the support rib in the receiving recess.

[0023] As a possible implementation, the support portion includes two support plates and a partition plate, the two support plates are arranged at intervals along a second direction perpendicular to both the first direction and the up and down directions, and the partition plate is located between the two support plates to separate the recess between the two support plates into two receiving recesses.

[0024] The cooperation between the two support plates and the partition plate can make the entire support structure more stable, thereby better bearing external forces and preventing the structure from shaking or deforming.

[0025] As a possible implementation, the bed frame connecting member further comprises a first supporting rib, the first supporting rib being connected to a corresponding supporting plate and connected to the base. In the bottom view, the first supporting rib is in a curved structure.

[0026] The first support rib can improve the connection strength between the support plate and the base. When subjected to external force, the first support rib can effectively share the stress and enhance the overall stability of the bed frame connection. Compared with the straight line structure, the curved structure can significantly increase the contact area between the first support rib and the base, improve the connection strength between the first support rib and the base, and thus enhance the overall stability of the bed frame connection.

[0027] As a possible implementation, two first support ribs are provided on one side of the support plate facing away from the other support plate. The two first support ribs are spaced apart along a first direction, and the two first support ribs gradually lower along the direction facing away from the support plate and the spacing between them gradually decreases.

[0028] The position where the first support rib is connected to the support plate has a large contact area, so the first support rib can provide reliable support for the support plate. In the direction away from the support plate, the two first support ribs gradually approach each other, so the contact area with the base can be increased, thereby improving the connection strength between the first support rib and the base.

[0029] As a possible implementation, the bed frame connector also includes a second support rib, which is connected to the first support rib and the support plate. The distance from the second support rib to the top of the support plate is D3, and the distance from the top of the support plate to the base is D4, where D3 / D4=1 / 3.

[0030] The second support rib can improve the connection strength between the support plate and the first support rib. When subjected to external force, the second support rib can effectively share the stress and enhance the overall stability of the bed frame connection. According to the implementation of the present disclosure, the second support rib is located near the top of the support plate, which can enhance the connection strength between the support plate and the first support rib.

[0031] In a second aspect, the present disclosure further provides a bed frame, comprising the bed frame connector, a support beam and two support ribs as described above. The support beam is provided with a connection hole, and after the connection portion passes through the connection hole, it is rotated and switched from a first position to a second position, so that the bed frame connector can be fixed to the support beam, wherein when the connection portion is in the first position, the projection of the connection portion on a plane perpendicular to the up and down direction completely falls into the projection of the connection hole on the plane; when the connection portion is in the second position, the projection of the connection portion on the plane partially overlaps with the projection of the connection hole on the plane. One end of each support rib can be mounted on the bed frame connector through a receiving recess, and the two support ribs extend along the first direction.

[0032] In a third aspect, the present disclosure further provides a bed frame, comprising the bed frame connector, a support beam and two support ribs as described above. The support beam is provided with a connection hole and two first positioning recesses, the two first positioning recesses are opposite to each other across the connection hole, and after the connection part passes through the connection hole, it is rotated and switched from the first position to the second position, so that the bed frame connector can be fixed to the support beam, wherein when the connection part is located at the first position, the projection of the connection part on a plane perpendicular to the up and down direction completely falls into the projection of the connection hole on the plane, and the clamping boss is separated from the support beam; when the connection part is located at the second position, the projection of the connection part on the plane partially overlaps with the projection of the connection hole on the plane, the clamping boss is pressed against the support beam, and each first positioning protrusion is located in a corresponding first positioning recess. One end of each support rib can be installed on the bed frame connector through the receiving recess, and the two support ribs extend along the first direction.

[0033] In a fourth aspect, the present disclosure further provides a bed frame, comprising the bed frame connector, a support beam and two support ribs as described above. The support beam is provided with a connection hole, and the connection hole cooperates with the connection portion. After the connection portion passes through the connection hole, it is rotated and switched from the first position to the second position, so that the bed frame connector can be fixed to the support beam, wherein when the connection portion is in the first position, the projection of the connection portion on a plane perpendicular to the up and down direction completely falls into the projection of the connection hole on the plane; when the connection portion is in the second position, the projection of the connection portion on the plane partially overlaps with the projection of the connection hole on the plane. One end of each support rib can be installed on the bed frame connector through a receiving recess, and the two support ribs extend along the first direction, and the bottom wall of the support rib is provided with a second positioning recess, and when the support rib is installed in the receiving recess, the second positioning protrusion extends into the second positioning recess.

[0049] The following is an exemplary description of the embodiments of the present disclosure in conjunction with the accompanying drawings. It should be understood that the present disclosure can be implemented in a variety of ways and should not be construed as being limited to the embodiments described here. The embodiments described here are only for a more thorough and clear understanding of the present disclosure.

[0050] refer to Figure 1Some detachable bed frames usually include a support beam 10 and a plurality of support ribs 20. The support ribs 20 are collinear in pairs and spaced apart in a direction perpendicular to the support beam 10. The support ribs 20 are supported on the support beam 10. In order to connect the support beam 10 and the support ribs 20, some support beams 10 are provided with sinks, and the support ribs 20 can be placed in the sinks and fixed to the support beam 10 by screws. However, this installation method requires more parts, and the installation process is time-consuming and labor-intensive. In order to simplify the installation process, some bed frames include bed frame connectors, which are welded to the support beam 10, and the support ribs 20 are connected to the support beam 10 by connectors, thereby achieving the fixation of the two. However, this type of bed frame has the problem of large packaging volume and is not conducive to transportation.

[0051] In view of this, refer to Figures 1 to 3 The present disclosure provides a bed frame 100, which includes a bed frame connector 30. The bed frame connector 30 includes a base 31, a connector 32, and a support portion 33. The connector 32 includes a column 321 and two action portions 322, the column 321 protrudes downward from the base 31, each action portion 322 protrudes outward from the outer circumference of the column 321, and the two action portions 322 are opposite to each other across the column 321. The support portion 33 is provided on the upper side of the base 31 and is provided with two receiving recesses 331, the two receiving recesses 331 are arranged along a first direction perpendicular to the up-down direction, and the upper side and the outer side of each receiving recess 331 in the first direction are open.

[0052] refer to Fig.10 The top wall 11 of the support beam 10 is provided with a connection hole 12, and the connection portion 32 can pass through the connection hole 12. Figure 7 Since the base 31 and the action portion 322 are separated in the vertical direction, after the connection portion 32 rotates a certain angle, the top wall 11 of the support beam 10 is located between the base 31 and the action portion 322. When the bed frame connection member 30 has a tendency to deviate or escape from the connection hole 12, the top wall 11 of the support beam 10 can suppress this tendency, so that the bed frame connection member 30 maintains a connection relationship with the support beam 10. One end of the support rib 20 can be installed on the bed frame connection member 30 through the receiving recess 331 and supported by the support portion 33. According to the embodiment of the present disclosure, the bed frame connection member 30 can be connected to the support beam 10 through the connection portion 32, and the support portion 33 of the bed frame connection member 30 can provide support for the support rib 20. Therefore, no additional installation tools are required when connecting the support rib 20 and the support beam 10. This implementation method can save installation time and reduce installation difficulty. In addition, since the bed frame connection member 30 does not rely on the existence of the support beam 10, this implementation method can also reduce the packaging volume and reduce transportation costs.

[0053] It is understood that in the present disclosure, directional descriptions such as "up" and "down" are relative rather than absolute. These directional descriptions are applicable when the elements in the present disclosure are in the placement postures and placement positions shown in the figures. It should be noted that in the drawings of the present disclosure, arrows Z+ and Z- are used to indicate the upper side and the lower side of the up and down directions, respectively; arrows X are used to indicate a first direction, which is perpendicular to the up and down directions; arrows Y are used to indicate a second direction, which is perpendicular to both the first direction and the up and down directions.

[0054] Figure 4A and Figure 4B FIG. 3 shows the installation process of the bed frame connector 30. After the connecting portion 32 passes through the connecting hole 12, it rotates from the first position to the second position, and the bed frame connector 30 can be fixed to the support beam 10. Figure 4A When the connecting portion 32 is located at the first position, the projection of the connecting portion 32 on the plane perpendicular to the up-down direction completely falls into the projection of the connecting hole 12 on the plane. Figure 4B When the connecting portion 32 is located at the second position, the projection of the connecting portion 32 on the plane partially overlaps with the projection of the connecting hole 12 on the plane.

[0055] It is understood that the shape of the connecting portion 32 can be configured in various forms, and the present disclosure does not impose any particular limitation on this. Figure 4A From the bottom view, the column 321 is a circle, and each action portion 322 is a fan ring. Of course, in some other embodiments, the connection portion can also be rectangular, as long as the rotation range of the connection portion is within the support beam 10.

[0056] refer to Figure 3 and Figure 7 , the two action parts 322 are opposite to each other along the first direction with the column part 321 therebetween. After the support rib 20 is connected to the support beam 10, on either side of the column part 321 along the first direction, from top to bottom, there are the support rib 20, the base part 31, the support beam 10 and the action part 322. In this way, the pressure of the support rib 20 acting on the base part 31 can be transmitted downward, so that the gap between the base part 31 and the action part 322 is reduced, thereby clamping the support beam 10, which helps to improve the stability of the connection between the bed frame connecting member 30 and the support beam 10.

[0057] refer to Figure 3 The bed frame connecting member 30 may further include two pressing bosses 341, which protrude downward from the base 31 and are opposite to each other across the connecting portion 32. Figure 8Since the pressing boss 341 protrudes downward from the base 31, the pressing boss 341 can press against the top wall 11 of the support beam 10, so that the bed frame connecting member 30 as a whole has a downward movement trend, thereby enhancing the connection stability between the bed frame connecting member 30 and the support beam 10. In addition, since the two pressing bosses 341 are arranged opposite to each other with the connecting portion 32 in between, it can also ensure uniform force distribution.

[0058] refer to Figure 5 , the two acting parts 322 are arranged at intervals along a first direction, the two pressing bosses 341 are arranged at intervals along a second direction perpendicular to both the first direction and the up-down direction, and the distance D1 between the two acting parts 322 is smaller than the distance D2 between the two pressing bosses 341. The space for the two acting parts 322 to rotate needs to be located inside the support beam 10, therefore, the distance between the two acting parts 322 is constructed to be smaller, which is beneficial to reducing the size of the support beam 10. In addition, the arrangement direction of the two acting parts 322 is perpendicular to the arrangement direction of the two pressing bosses 341, and the support beam 10 can be pressed against in two perpendicular directions of the support beam 10, thereby enhancing the reliability of the connection between the bed frame connecting member 30 and the support beam 10.

[0059] refer to Figure 3 , Figure 4A and Figure 4B The lower end surface of each pressing boss 341 is provided with a first positioning protrusion 342 protruding downward. Fig.10 , two first positioning recesses 13 are provided on the top wall 11 of the support beam 10. When the bed frame connecting member 30 rotates to the second position, the first positioning protrusion 342 will be located in a corresponding first positioning recess 13. At this time, if the bed frame connecting member 30 moves in a direction away from the second position on a plane perpendicular to the up-down direction, the first positioning recess 13 can limit the displacement of the first positioning protrusion 342 in this direction, so as to ensure that the bed frame connecting member 30 is fixed at the target position (i.e. Figure 4B second position shown).

[0060] Furthermore, a guide surface 343 is provided on the side of the first positioning protrusion 342 facing away from the connecting portion 32. The guide surface 343 is located on the side of the first positioning protrusion 342 facing away from the connecting portion 32 and extends upwardly and obliquely from the lower end surface of the first positioning protrusion 342 along the direction facing away from the connecting portion 32 to the lower end surface of the pressing boss 341. Figure 8In the process of installing the bed frame connecting member 30 in place, the lower end surface of the first positioning protrusion 342 and the guide surface 343 can pass through the top wall 11 of the support beam 10 in sequence (that is, the first positioning protrusion 342 moves from the left side to the right side in the figure), and finally the first positioning protrusion 342 extends into the first positioning recess 13, and the pressing boss 341 presses against the top wall 11 of the support beam 10. In other words, the guide surface 343 forms a gentle slope between the lower end surface of the first positioning protrusion 342 and the lower end surface of the pressing boss 341, so that the first positioning protrusion 342 can smoothly enter the first positioning recess 13.

[0061] refer to Figure 5 and Figure 8 In the bottom view, the first positioning protrusion 342 is semicircular or inferior arc-shaped, and the straight line segment of the semicircular or inferior arc-shaped is located on the side of the semicircular or inferior arc-shaped that faces away from the connecting portion 32, and the straight line segment is the connecting segment between the guide surface 343 and the lower end surface of the pressing boss 341. In this way, when the first positioning protrusion 342 enters the first positioning recess 13, the lower height portion of the first positioning protrusion 342 always enters the first positioning recess 13 first, so that the installation process can be smoother.

[0062] refer to Figure 3 and Figure 8 The base 31 is provided with two through slots 311 corresponding to the two clamping bosses 341, each through slot 311 penetrates the base 31 and partially surrounds a corresponding clamping boss 341. According to the implementation of the present disclosure, the through slots 311 can increase the elasticity of the clamping boss 341, making it easy to yield and deform after being subjected to force. In this way, when the bed frame connecting member 30 is installed to the target position, the clamping boss 341 can deform upward, so that after passing over the support beam 10, it contacts the top wall 11 thereof and presses against the top wall 11 of the support beam 10.

[0063] refer to Figure 3 The base 31 includes two ends 312 extending along the second direction, each clamping boss 341 is connected to a corresponding end 312, and the through slot 311 surrounds the side of the clamping boss 341 close to the connecting portion 32. If the through slot 311 surrounds the side of the clamping boss 341 close to the end 312, the structural strength of the end 312 will be weakened, so that the end 312 is easily damaged when subjected to external force. According to the implementation method of the present disclosure, the through slot 311 is located on the inner large surface of the base 31, so that the structural strength of the base 31 can be weakened to a lesser extent. In this way, the through slot 311 can increase the elasticity of the clamping boss 341, making it easy to yield and deform after being subjected to force, and will not weaken the structural strength of the base 31 too much.

[0064] refer to Figure 3 and Figure 5In the second direction, as they move away from the connecting portion 32 , the first positioning protrusion 342 and the end portion 312 are arranged in sequence and spaced apart from each other.

[0065] In the process of installing the bed frame connector 30 to the target position, the pressing boss 341 contacts the top wall 11 of the support beam 10 after passing over it. Since the lower end surface of the first positioning protrusion 342 is lower than the lower end surface of the pressing boss 341, the pressing boss 341 will continue to move upward, so that the first positioning protrusion 342 contacts the top wall of the support beam 10 until the first positioning protrusion 342 moves into the corresponding first positioning recess 13. In the implementation of the present disclosure, the first positioning protrusion 342 is spaced apart from the end 312 in the second direction, and the end 312 is the edge of the base 31. Therefore, when the bed frame connector 30 rotates around the connecting portion 32, in the process of installing the bed frame connector 30 to the target position, the first positioning protrusion 342 can have a shorter rotation radius, thereby shortening the stroke of friction with the top wall 11 of the support beam 10, so that the installation operation can be completed more easily. In addition, when the clamping boss 341 yields and deforms under stress, the portion close to the end 312 will be restricted by the end 312, while the portion away from the end 312 can obtain a larger deformation. The first positioning protrusion 342 is designed to be spaced from the end 312, so that the portion of the clamping boss 341 where the first positioning protrusion 342 is located can easily yield and deform, thereby passing over the support beam 10 and continuing to move to the target position.

[0066] Continue to refer Figure 3 and Figure 7 The lower end surface of the base 31 is provided with two pressing convex point groups 35, the two pressing convex point groups 35 are opposite to each other along the first direction across the connecting portion 32, and each pressing convex point group 35 includes a plurality of pressing convex points 351, and the plurality of pressing convex points 351 are arranged at intervals along a second direction that is substantially perpendicular to both the first direction and the up-down direction. The pressing convex points 351 can further reduce the gap between the base 31 and the action portion 322, so that after the bed frame connecting member 30 is connected to the support beam 10, the base 31 and the action portion 322 can clamp the top wall 11 of the support beam 10, which helps to improve the stability of the connection.

[0067] It is understood that if the size of the pressing protrusion 351 is too large, it will exceed the top wall 11 of the support beam 10 in the first direction. Therefore, in order for the pressing protrusion 351 to be pressed against the top wall 11 of the support beam 10, the size of the pressing protrusion 351 needs to be limited. Figure 5 , the area of ​​the minimum circumscribed circle of the pressing protrusion 351 can be smaller than 1 / 5 of the minimum circumscribed circle of the connecting portion 32 .

[0068] Back to Figure 2 , the bottom wall of each receiving recess 331 may be provided with a second positioning protrusion 332. Fig.11A second positioning recess 21 is provided at the bottom of the support rib 20. When the support rib 20 is installed in the receiving recess 331, the second positioning protrusion 332 is located in the second positioning recess 21, thereby limiting the displacement of the support rib 20 in a plane perpendicular to the up and down directions and fixing the support rib 20 in the receiving recess 331.

[0069] It can be understood that the support rib 20 is installed on the receiving recess 331 from top to bottom. In order to make the second positioning recess 21 easily align with the second positioning protrusion 332, the second positioning protrusion 332 can be constructed to gradually expand as it approaches the base 31. For example, the second positioning protrusion 332 can be a prism or a frustum.

[0070] It can be understood that the second positioning protrusion 332 can be connected to the base 31 or can be a part of the base 31 .

[0071] refer to Figure 6 Each receiving recess 331 has two side surfaces 3311, the two side surfaces 3311 are opposite to each other in the second direction, and the distance between the two side surfaces 3311 gradually increases upward. In this way, when the bed frame connector 30 is formed by molding, the mold can easily withdraw from between the two side surfaces 3311.

[0072] Continue to refer Figure 6 A pair of pressing ridges 3312 are respectively provided on the two side surfaces 3311 and face each other (the other pressing ridge 3312 is blocked in the figure and is not shown), each pressing ridge 3312 extends in the up-down direction, each pressing ridge 3312 has a pressing surface facing the other pressing ridge 3312, and the distance between the two pressing surfaces is substantially constant in the up-down direction. When the support rib 20 is mounted on the receiving recess 331, the support rib 20 is located between the two pressing surfaces, thereby limiting the displacement of the support rib 20 in the second direction.

[0073] It should be noted that the number of the pressing ribs 3312 in the embodiment of the present disclosure is two pairs, and the above description is only for one pair. Of course, in other embodiments, the number of the pressing ribs 3312 may be more than two pairs.

[0074] To form the receiving recess 331, refer to Figure 2 The support portion 33 may include two support plates 333 and a partition plate 334. The two support plates 333 are spaced apart along the second direction, and the partition plate 334 is located between the two support plates 333 to separate the recessed portion between the two support plates 333 into two receiving recessed portions 331. The cooperation between the two support plates 333 and the partition plate 334 can make the entire support portion 33 structure more stable, thereby better bearing external forces and preventing the structure from shaking or deforming.

[0075] Continue to refer Figure 2The bed frame connector 30 may further include a first support rib 335, which is connected to a corresponding support plate 333 and to the base 31. In the bottom view, the first support rib 335 is in a curved structure. The first support rib 335 can improve the connection strength between the support plate 333 and the base 31. When subjected to external force, the first support rib 335 can effectively share the stress and enhance the overall stability of the bed frame connector 30. Compared with the straight line structure, the curved structure can significantly increase the contact area between the first support rib 335 and the base 31, improve the connection strength between the first support rib 335 and the base 31, and thus enhance the overall stability of the bed frame connector 30.

[0076] Continue to refer Figure 2 , two first support ribs 335 are provided on one side of the support plate 333 facing away from the other support plate 333, and the two first support ribs 335 are arranged at intervals along the first direction, and the two first support ribs 335 are gradually lowered and the spacing is gradually reduced along the direction facing away from the support plate 333. The position where the first support rib 335 is connected to the support plate 333 has a large contact area, so the first support rib 335 can provide reliable support for the support plate 333. In the direction away from the support plate 333, the two first support ribs 335 gradually approach each other, so that the contact area between the first support rib 335 and the base 31 can be increased, and the connection strength between the first support rib 335 and the base 31 can be improved.

[0077] Continue to refer Figure 2 The bed frame connector 30 may further include a second support rib 336, which is connected to the first support rib 335 and to the support plate 333. Fig. 9 , the distance from the second support rib 336 to the top of the support plate 333 is D3, the distance from the top of the support plate 333 to the base 31 is D4, and D3 / D4=1 / 3. The second support rib 336 can improve the connection strength between the support plate 333 and the first support rib 335. When subjected to external force, the second support rib 336 can effectively share the stress and enhance the overall stability of the bed frame connector 30. According to the implementation of the present disclosure, the second support rib 336 is located near the top of the support plate 333, which can enhance the connection strength between the support plate 333 and the first support rib 335.
