Description

Technical Field

[0001] This utility model relates to the field of bed technology, specifically to a modular bed frame. Background Technology

[0002] Traditional iron-framed beds are welded from iron parts, making them impossible to disassemble and extremely inconvenient to move. Although some modular bed frames have appeared on the market, most require a large number of screws to splice the crossbars and longitudinal bars to form the bed frame, and then assemble the bed frame, bed body, and bed legs. Due to the use of a large number of screws, the assembly and disassembly process is very cumbersome. In order to simplify the assembly steps and reduce the difficulty, existing iron-framed beds will set some structures as components, such as the iron-framed bed for easy installation disclosed in Chinese Utility Model Patent No. 202121020631.1. However, the connecting parts of this iron-framed bed are only installed on the legs with bolts, without the setting of limiting structures. After a period of use, the bolts will loosen, and the bed frame will wobble, resulting in low structural stability of the bed frame.

[0003] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Utility Model Content

[0004] The purpose of this utility model is to address the above-mentioned shortcomings by providing a modular bed frame that incorporates inner and outer right-angle baffles on the legs to form a right-angle groove structure for limiting the installation of longitudinal and transverse side bars. This effectively prevents the bed frame from wobbling and avoids the inability of traditional bed frames to effectively ensure structural stability by relying solely on bolt tightening force.

[0005] The solution adopted by this utility model to solve the technical problem is: a modular bed frame, including a longitudinal side rod assembly, a transverse side rod assembly, a frame assembly, and a leg assembly. The longitudinal side rod assembly includes two symmetrically arranged longitudinal side rods, and the transverse side rod assembly includes two symmetrically arranged transverse side rods. The two longitudinal side rods and the two transverse side rods together form a square frame. The frame assembly includes several frame rods, and the transverse side rods are provided with several mounting slots. The frame rods are respectively installed in the mounting slots. The leg assembly includes four legs. The two ends of the longitudinal side rods and transverse side rods are respectively detachably installed on the legs. The legs include leg rods, inner right-angle baffles, and outer right-angle baffles. The upper side of the leg rods is provided with a right-angle base plate. The inner right-angle baffles and outer right-angle baffles are arranged parallel to each other on the right-angle base plate to form right-angle slots for installing the longitudinal side rods and transverse side rods.

[0006] Furthermore, in order to detachably install the longitudinal and transverse side bars onto the outriggers, both ends of the longitudinal and transverse side bars are detachably installed onto the outriggers via bolt and nut assemblies. The bolt and nut assemblies include two side bolts, two side nuts, and two end face bolts. The side bolts pass sequentially through the outer right-angle baffle, the side of the longitudinal or transverse side bar, and the inner right-angle baffle before being threadedly connected to the side nuts, thereby fixing the longitudinal and transverse side bars onto the outriggers. The end face bolts pass sequentially through the outer right-angle baffle and the side of the transverse side bar before being threadedly connected to the end face of the longitudinal side bar to further fix the longitudinal and transverse side bars onto the outriggers.

[0007] Furthermore, for installing the bolt and nut assembly, the sides of both ends of the longitudinal and transverse side bars are provided with side holes for installing side bolts. The side of the transverse side bar, located outside the side holes, is also provided with two through holes for installing end face bolts. The two through holes and the side holes are triangularly distributed. The end face of the longitudinal side bar is provided with two threaded holes for installing end face bolts. The ends of the inner and outer right-angle baffles are respectively provided with first mounting holes for installing side bolts. The outer right-angle baffle is also provided with two second mounting holes for installing end face bolts.

[0008] Furthermore, in order to form a component structure of the transverse side bar to simplify the bed frame structure, the transverse side bar includes a vertical bar and two horizontal bars hinged to the upper end of the vertical bar. The upper side of the vertical bar is provided with a hinge seat for mounting the horizontal bars. The two horizontal bars are respectively hinged to both sides of the hinge seat. The lower side of the horizontal bar that is hinged to the hinge seat is provided with a chamfer. The mounting groove is provided on the horizontal bar.

[0009] Furthermore, in order to improve the structural stability of the bed frame, the combined bed frame also includes a longitudinal center rod, and the hinge seat is provided with a fixing seat for installing the longitudinal center rod. The fixing seat is located inside the hinge seat, and the two ends of the longitudinal center rod are respectively fixedly installed on the two fixing seats.

[0010] Furthermore, in order to form a longitudinal side bar assembly structure to simplify the bed frame structure, the longitudinal side bar includes a vertical bar and two horizontal bars hinged to the upper end of the vertical bar. The upper side of the vertical bar is provided with a hinge seat for mounting the horizontal bars. The two horizontal bars are respectively hinged to both sides of the hinge seat. The lower side of the horizontal bar that is hinged to the hinge seat is provided with a chamfer.

[0011] Furthermore, in order to improve the structural stability of the bed frame, the combined bed frame also includes a transverse center rod, which includes a vertical rod and two horizontal rods hinged to the upper end of the vertical rod. The upper side of the vertical rod is provided with a hinge seat for mounting the horizontal rods. The two horizontal rods are respectively hinged to both sides of the hinge seat. The lower side of the horizontal rod hinged to the hinge seat is provided with a chamfer. The horizontal rod is provided with several mounting slots.

[0012] The hinge seat is provided with a mounting seat for installing the transverse center rod. The mounting seat is located inside the hinge seat. The two ends of the transverse center rod are respectively fixedly installed on the two mounting seats. One end of the longitudinal center rod and the skeleton rod are installed on the transverse side rod, and the other end of the longitudinal center rod and the skeleton rod are installed on the transverse center rod.

[0013] Furthermore, to distribute the supporting force of the vertical rod on the horizontal rod, the combined bed frame also includes a support assembly, which includes a support block, a limiting block, and a return spring. The vertical rod is provided with a limiting groove located below the hinge seat. The limiting block is slidably installed in the limiting groove via the return spring. There are two support blocks, which are respectively located on both sides of the limiting block to support the horizontal rod on both sides of the vertical rod. This allows the limiting block to automatically embed into the limiting groove when the horizontal rod is unfolded and to retract from the limiting groove when the horizontal rod is retracted.

[0014] Compared with existing technologies, this utility model has the following advantages: This utility model forms right-angle grooves by setting inner and outer right-angle baffles on the support legs, thereby limiting the connection between the longitudinal and transverse side rods and the support legs. The inner right-angle baffles prevent the longitudinal and transverse side rods from shifting inwards, and the outer right-angle baffles prevent the longitudinal and transverse side rods from shifting outwards. Combined with side bolts and end bolts, a stable connection is achieved between the support legs and the longitudinal and transverse side rods. Compared with traditional bed frames that rely solely on bolt connections, this utility model has higher connection strength and can more effectively reduce swaying during bed frame use. Furthermore, because the crossbars are hinged to the vertical rods, to avoid hinge... The hinged seat interferes with the rotation of the crossbar. Both sides of the hinged seat have slotted bottom surfaces, meaning the contact surface between the vertical and horizontal bars is only the upper surface of the vertical bar. This small contact area cannot provide sufficient support for the horizontal bar. Over time, stress concentration at the connection between the horizontal and vertical bars can easily lead to breakage and deformation. To avoid this, this invention provides a support structure below the horizontal bar to distribute the support force. Furthermore, when the horizontal bar is extended, the limiting block automatically embeds into the limiting groove under the action of a spring. When the horizontal bar is retracted, the limiting block is manually pulled out of the limiting groove before the horizontal bar is retracted, ensuring that the limiting block does not interfere with the extension and retraction of the horizontal bar, making it extremely convenient to use.

Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0023] Example 1: As Figure 1 As shown, this embodiment provides a modular bed frame, including a longitudinal side rod assembly, a transverse side rod assembly, a frame assembly, and a leg assembly. The longitudinal side rod assembly includes two symmetrically arranged longitudinal side rods 1, and the transverse side rod assembly includes two symmetrically arranged transverse side rods 2. The two longitudinal side rods 1 and the two transverse side rods 2 together form a square frame. The frame assembly includes a plurality of frame rods 3, and the transverse side rods 2 are provided with a plurality of mounting slots 205, in which the plurality of frame rods 3 are respectively installed. The support leg assembly includes four support legs 4. The two ends of the longitudinal side rod 1 and the transverse side rod 2 are detachably installed on the support legs 4. The adjacent ends of the longitudinal side rod 1 and the transverse side rod 2 are installed on the same support leg 4. The support leg 4 includes a leg rod 401, an inner right-angle baffle 402 and an outer right-angle baffle 403. The upper side of the leg rod 401 is provided with a right-angle base plate. The inner right-angle baffle 402 and the outer right-angle baffle 403 are arranged in parallel on the right-angle base plate to form a right-angle groove for installing the longitudinal side rod 1 and the transverse side rod 2.

[0024] In this embodiment, in order to detachably install the longitudinal side rod 1 and the transverse side rod 2 onto the support leg 4, both ends of the longitudinal side rod 1 and the transverse side rod 2 are detachably installed onto the support leg 4 via bolt and nut assembly 5. The bolt and nut assembly 5 includes two side bolts 501, two side nuts 502, and two end face bolts 503. The side bolts 501 pass through the outer right-angle baffle 403, the side of the longitudinal side rod 1 or the side of the transverse side rod 2, and the inner right-angle baffle 402 in sequence, and are then threadedly connected to the side nuts 502 to fix the longitudinal side rod 1 and the transverse side rod 2 onto the support leg 4. The end face bolts 503 pass through the outer right-angle baffle 403 and the side of the transverse side rod 2 in sequence, and are then threadedly connected to the end face of the longitudinal side rod 1 to further fix the longitudinal side rod 1 and the transverse side rod 2 onto the support leg 4.

[0025] In this embodiment, for the installation of the bolt and nut assembly 5, the sides of both ends of the longitudinal side rod 1 and the transverse side rod 2 are provided with side holes for installing side bolts 501. The side of the transverse side rod 2 is also provided with two through holes for installing end face bolts 503, located outside the side holes. The two through holes and the side holes are distributed in an isosceles triangle. The end face of the longitudinal side rod 1 is provided with two threaded holes for installing end face bolts 503. The two ends of the inner right-angle baffle 402 and the outer right-angle baffle 403 are respectively provided with first mounting holes for installing side bolts 501. The outer right-angle baffle 403 is also provided with two second mounting holes for installing end face bolts 503.

[0026] In this embodiment, in order to form the component structure of the transverse side bar 2 and simplify the bed frame structure, the transverse side bar 2 includes a vertical bar 202 and two horizontal bars 201 hinged to the upper end of the vertical bar 202. The upper side of the vertical bar 202 is provided with a hinge seat 203 for mounting the horizontal bars 201. The two horizontal bars 201 are respectively hinged to both sides of the hinge seat 203. The lower side of the end of the horizontal bar 201 that is hinged to the hinge seat 203 is provided with a chamfer. The mounting groove 205 is provided on the horizontal bar 201.

[0027] In this embodiment, in order to improve the structural stability of the bed frame, the combined bed frame also includes a longitudinal center rod 6, and the hinge seat 203 of the transverse side rod 2 is provided with a fixing seat 204 for installing the longitudinal center rod 6. The fixing seat 204 is located inside the hinge seat 203 of the transverse side rod 2, and the two ends of the center rod are respectively fixedly installed on the two fixing seats 204.

[0028] In this embodiment, in order to share the supporting force of the vertical bar 202 on the horizontal bar 201, the combined bed frame also includes a support assembly 8, which includes a support block 801, a limiting block 802, and a return spring 804. The vertical bar 202 is provided with a limiting groove 803 located below the hinge seat 203. The limiting block 802 is slidably installed in the limiting groove 803 via the return spring 804. There are two support blocks 801, which are respectively provided on both sides of the limiting block 802 to support the horizontal bars 201 on both sides of the vertical bar 202. This allows the limiting block 802 to automatically embed into the limiting groove 803 when the horizontal bar 201 is unfolded and to exit the limiting groove 803 when the horizontal bar 201 is retracted.

[0029] Example 2: As Figure 2-5 As shown, this embodiment provides a modular bed frame, including a longitudinal side rod assembly, a transverse side rod assembly, a frame assembly, and a leg assembly. The longitudinal side rod assembly includes two symmetrically arranged longitudinal side rods 1, and the transverse side rod assembly includes two symmetrically arranged transverse side rods 2. The two longitudinal side rods 1 and the two transverse side rods 2 together form a square frame. The frame assembly includes several frame rods 3, and the transverse side rods 2 are provided with several mounting slots 205. The several frame rods 3 are respectively installed in each mounting slot 205. The leg assembly includes four legs 4. The two ends of the longitudinal side rods 1 and the transverse side rods 2 are detachably installed on the legs 4. The legs 4 include leg rods 401, inner right-angle baffles 402, and outer right-angle baffles 403. The upper side of the leg rods 401 is provided with a right-angle base plate. The inner right-angle baffles 402 and the outer right-angle baffles 403 are arranged parallel to each other on the right-angle base plate to form right-angle slots for installing the longitudinal side rods 1 and the transverse side rods 2. The difference between this embodiment and embodiment 1 is that this embodiment also includes a transverse center rod 7.

[0030] In this embodiment, in order to form the component structure of the longitudinal side bar 1 and simplify the bed frame structure, the longitudinal side bar 1 includes a vertical bar 202 and two horizontal bars 201 hinged to the upper end of the vertical bar 202. The upper side of the vertical bar 202 is provided with a hinge seat 203 for mounting the horizontal bars 201. The two horizontal bars 201 are respectively hinged to both sides of the hinge seat 203. The lower side of the end of the horizontal bar 201 that is hinged to the hinge seat 203 is provided with a chamfer.

[0031] In this embodiment, to improve the structural stability of the bed frame, the combined bed frame further includes a transverse center rod 7. The transverse center rod 7 includes a vertical rod 202 and two horizontal rods 201 hinged to the upper end of the vertical rod 202. The upper side of the vertical rod 202 is provided with a hinge seat 203 for mounting the horizontal rods 201. The two horizontal rods 201 are respectively hinged to both sides of the hinge seat 203. The lower side of the end of the horizontal rod 201 that is hinged to the hinge seat 203 is provided with a chamfer. The horizontal rod 201 is provided with a plurality of mounting slots 205.

[0032] The hinge seat 203 is provided with a mounting seat for installing the transverse center rod 7. The mounting seat is located inside the hinge seat 203. The two ends of the transverse center rod 7 are respectively fixedly installed on the two mounting seats. One end of the longitudinal center rod 6 and the skeleton rod 3 is installed on the transverse side rod 2, and the other end of the longitudinal center rod 6 and the skeleton rod 3 is installed on the transverse center rod 7.

[0033] This invention utilizes an inner right-angle baffle 402 and an outer right-angle baffle 403 on the support leg 4 to form a right-angle groove, thereby limiting the connection between the longitudinal side rod 1 and the transverse side rod 2 and the support leg 4. The inner right-angle baffle 402 prevents the longitudinal side rod 1 and the transverse side rod 2 from shifting inward, while the outer right-angle baffle 403 prevents them from shifting outward. Combined with side bolts 501 and end bolts 503, this achieves a stable connection between the support leg 4 and the longitudinal side rod 1 and the transverse side rod 2. Compared to traditional bed frames that rely solely on bolt connections, this invention offers higher connection strength and effectively reduces wobbling during bed frame use. Furthermore, because the crossbar 201 is hinged to the vertical rod 202, to prevent the hinge seat 203 from interfering with the rotation of the crossbar 201, two... Both sides of the bottom surface are slotted, meaning that the contact surface between the vertical bar 202 and the horizontal bar 201 is only the upper end surface of the vertical bar 202. The small contact surface between the two cannot provide sufficient support for the horizontal bar 201. Under long-term use, the connection between the horizontal bar 201 and the vertical bar 202 is prone to breakage and deformation due to stress concentration. To avoid this situation, this utility model sets a support structure below the horizontal bar 201 to share the support force on the horizontal bar 201. Furthermore, when the horizontal bar 201 is unfolded, the limiting block 802 is automatically embedded in the limiting groove 803 under the action of the spring 804. When the horizontal bar 201 is retracted, the limiting block 802 is first manually pulled out of the limiting groove 803, and then the horizontal bar 201 is retracted, ensuring that the limiting block 802 does not interfere with the unfolding and retraction of the horizontal bar 201, making it extremely convenient to use.

[0034] The above description is merely an embodiment of this utility model and does not limit the scope of patent protection of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this utility model.
