Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a support splicing component, support legs and bed frame. Background Technology

[0002] In the field of electric beds, the height of the bed legs, as an important structure supporting the bed base, usually needs to be adjusted according to different furniture sizes or the needs of different users. Existing adjustable bed leg structures mainly include two types: threaded adjustment and multi-segment splicing.

[0003] While threaded adjustment mechanisms can achieve height adjustment, their adjustment stroke is limited by the thread length. Furthermore, in practical use, they suffer from time-consuming installation and difficult disassembly. Especially after the bed legs bear heavy loads for extended periods, the threaded parts are prone to locking, making disassembly difficult. Additionally, because the bed legs are mostly round, there is a lack of effective force points during operation, further complicating assembly and disassembly.

[0004] Multi-segment splicing structures achieve height variations through the combination of multiple splicing components, but existing splicing methods mostly rely on fasteners such as screws and nuts for connection. When tightening these structures, over-tightening can make subsequent disassembly difficult, while loosening can cause wobbling and insufficient stability.

[0005] Therefore, a support assembly, support legs, and bed frame that can be quickly installed and disassembled need to be designed. Utility Model Content

The arc-shaped groove includes: an insertion hole section for inserting the cylindrical limiting part, and an arc-shaped limiting section that communicates with the insertion hole section and extends circumferentially along the splicing body for clamping or releasing the cylindrical connecting part.

[0010] Optionally, the arc-shaped limiting segment includes two arc-shaped elastic clamping arms that extend from the insertion hole segment and are spaced apart; The two arc-shaped elastic clamping arms are separated from each other at the ends away from the insertion hole section, and their inner sides together form an arc-shaped hole structure for accommodating and limiting the cylindrical limiting part. The two arc-shaped elastic clamping arms can be elastically opened or returned to their original position in the radial direction to clamp or release the round rod connection.

[0011] Optionally, the upper end face edge extends upward to form a supporting upper edge, and the lower end face edge extends downward to form a supporting lower edge; The upper edges of two adjacent supports abut against each other; Furthermore, the sum of the heights of the upper edge of the supporting splice and the lower edge of the adjacent supporting splice matches the height of the round rod connection.

[0012] Optionally, the splicing body further includes a cylindrical peripheral wall; the upper end face and the lower end face are respectively formed by welding circular pieces to both ends of the peripheral wall. Another aspect of this utility model provides a support leg, including at least two support splicing components arranged coaxially from top to bottom as described above; adjacent support splicing components and the uppermost support splicing component are detachably connected via a rotating snap-fit ​​structure.

[0013] Optionally, the support foot also includes a support foot pad that is detachably connected to the lower end of the bottom support splice.

[0014] Optionally, the heights of the various support splicing components are different.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used to distinguish multiple parts or structures with the same or similar structures, and do not indicate any special limitation on the arrangement order or connection relationship.

[0022] Please refer to Figures 1 to 9 This utility model embodiment provides a support splicing component 10 for constructing an adjustable-height furniture support structure. The support splicing component 10 includes a splicing body 1 having an upper end surface 11 and a lower end surface 12.

[0023] The upper end face 11 is provided with a first rotating snap-fit ​​structure, and the lower end face 12 is provided with a second rotating snap-fit ​​structure that cooperates with the first rotating snap-fit ​​structure; so that the support splicing member 10 can be relatively rotated and snapped onto another support splicing member 10 or a furniture frame provided with the second rotating snap-fit ​​structure.

[0024] Understandably, the support splicing component 10 can be rotatably and securely engaged with the second rotatable and engaging structure of the previous support splicing component 10 via the first rotatable and engaging structure on its upper end face 11; and the topmost support splicing component 10 can be rotatably and securely engaged with the second rotatable and engaging structure at the bottom of the furniture frame via the first rotatable and engaging structure. This allows for quick assembly and disassembly, avoiding the difficulties in disassembly and wobbling caused by excessively tight or loose threaded connections. It also facilitates the quick assembly and adjustment of the furniture's height relative to the supporting surface through multiple support splicing components 10, adapting to different application scenarios.

[0025] Alternatively, please refer to Figure 4 and Figure 8In this embodiment, the first rotary snap-fit ​​structure includes two snap-fit ​​protrusions 2. The two snap-fit ​​protrusions 2 are arranged in a circumferential array along the axis of the splicing body 1 on the upper end face 11. To accommodate different design requirements, in other embodiments, the number of snap-fit ​​protrusions 2 in the first rotary snap-fit ​​structure can also be set to three, four or more, and there is no specific limitation on this.

[0026] The second rotary snap-fit ​​structure includes two arc-shaped slots 3. These two arc-shaped slots 3 engage with snap-fit ​​bosses 2 and are arranged circumferentially along the axis of the splicing body 1 on the lower end face 12 of the support splicing component 10. Understandably, the number of arc-shaped slots 3 is the same as the number of snap-fit ​​bosses 2 to ensure reliable rotary snap-fit ​​between the first and second rotary snap-fit ​​structures. Through this engagement method, adjacent support splicing components 10 can be quickly assembled and disassembled by rotation, while ensuring connection stability and positioning accuracy.

[0027] Specifically, please refer to Figures 7 to 9 In this embodiment, the snap-fit ​​boss 2 includes a round rod connecting portion 21 and a cylindrical limiting portion 22. The round rod connecting portion 21 extends upward from the upper end face 11. The cylindrical limiting portion 22 is disposed at the top end of the round rod connecting portion 21, and the diameter of the cylindrical limiting portion 22 is larger than the diameter of the round rod connecting portion 21, so as to form a limiting protrusion for snap-fit.

[0028] The arc-shaped groove 3 includes an insertion hole section o1 and an arc-shaped limiting section o2. The insertion hole section o1 is used for the insertion of the cylindrical limiting part 22. The arc-shaped limiting section o2 communicates with the insertion hole section o1 and extends circumferentially along the splicing body 1, and is used to clamp or release the cylindrical connecting part 21.

[0029] In use, align the cylindrical limiting part 22 of the supporting splicing component 10 with the insertion hole section o1 on the lower end face 12 of the other supporting splicing component 10, insert it from bottom to top, and then rotate it circumferentially by a preset angle. As the rotation proceeds, the cylindrical connecting part 21 is accommodated within the arc-shaped limiting section o2 and is secured by the limiting wall of the arc-shaped limiting section o2. The cylindrical limiting part 22 then enters the space inside the splicing body 1 and is limited by the arc-shaped limiting section o2, thereby achieving a stable and reliable rotational locking connection between the two supporting splicing components 10. When disassembly is required, simply rotate in the opposite direction to realign the cylindrical limiting part 22 with the insertion hole section o1, and the two supporting splicing components 10 can be separated. The disassembly and assembly process is quick and convenient.

[0030] Specifically, please refer to Figure 8 and Figure 9In this embodiment, the arc-shaped limiting segment o2 includes two arc-shaped elastic clamping arms 31. The two arc-shaped elastic clamping arms 31 extend from the insertion hole segment o1 and are spaced apart. The two arc-shaped elastic clamping arms 31 are separated from each other at the ends away from the insertion hole segment o1, and their inner sides together form an arc-shaped hole structure for accommodating and limiting the cylindrical limiting part 22; the two arc-shaped elastic clamping arms 31 can be elastically opened or returned to their original position in the radial direction to clamp or release the round rod connecting part 21.

[0031] During assembly, the cylindrical limiting part 22 is first inserted into the arc-shaped slot 3 through the insertion hole section o1, and then slid along the inner sides of the two arc-shaped elastic clamping arms 31 by relative rotation. During rotation, the cylindrical limiting part 22 compresses the two elastic clamping arms 31 to open radially; when rotated to the predetermined position, the elastic clamping arms 31 rebound under their own elastic force, and their inner sides adhere to the round rod connecting part 21, thereby achieving a locking and fixing. During disassembly, the cylindrical limiting part 22 is rotated in the opposite direction to return to the insertion hole section o1 position, the elastic clamping arms 31 open and release the round rod connecting part 21, thereby achieving quick separation. In this way, reliable rotational locking can be achieved without additional fasteners.

[0032] Alternatively, please refer to Figure 7 and Figure 8 In this embodiment, the edge of the upper end face 11 of the splicing body 1 extends upward to form a supporting upper edge 13, and the edge of the lower end face 12 of the splicing body 1 extends downward to form a supporting lower edge 14. Two adjacent supporting upper edges 13 and supporting lower edges 14 abut against each other; and the sum of the heights of the supporting upper edges 13 and the supporting lower edges 14 of the adjacent supporting splicing parts 10 matches the height of the round rod connecting portion 21. Thus, two adjacent supporting splicing parts 10 can be supported by the supporting upper edges 13 and supporting lower edges 14, and the limiting and fixing by the first and second rotary locking structures prevents the splicing parts from shaking or shifting; thereby achieving stable support.

[0033] Alternatively, please refer to Figure 8 In this embodiment, the splicing body 1 also includes a cylindrical peripheral wall; the upper end face 11 and the lower end face 12 are respectively formed by welding circular pieces to the two ends of the peripheral wall.

[0034] Please refer to Figures 1 to 5 Another aspect of this utility model embodiment provides a support leg 100, including at least two support splicing members 10 arranged coaxially from top to bottom as described above; wherein, the two adjacent support splicing members 10, as well as the uppermost support splicing member 10 and the furniture frame, are detachably connected by a rotating snap-fit ​​structure. Since this support leg 100 has all the structures and connection relationships of the support splicing members 10, it has all the advantages of the support splicing members 10, which will not be elaborated here.

[0035] Alternatively, please refer to Figure 4 and Figure 5 In this embodiment, the support foot 100 further includes a support foot pad 20 detachably connected to the lower end of the bottom support splice 10. Specifically, the support foot pad 20 can be threaded to the lower end of the bottom support splice 10. In this way, the support foot 100 can adapt to different ground surfaces while having better cushioning, shock absorption, or anti-slip performance.

[0036] Alternatively, please refer to Figure 5 In this embodiment, the heights of the various support splicing components 10 are different. This facilitates the selection of support splicing components of different heights to meet different height requirements.

[0037] Please refer to Figures 1 to 4 Another aspect of this utility model embodiment provides a bed frame 1000, including a bed frame frame 200 and support legs 100 as described above; the bottom of the bed frame frame 200 is provided with a second rotating snap-fit ​​structure; the first rotating snap-fit ​​structure of the uppermost support splicing member 10 of the support leg 10 is rotatably snapped with the second rotating snap-fit ​​structure at the bottom of the bed frame frame 200. Since the bed frame 1000 has all the structures and connection relationships of the support legs 100, it has all the advantages of the support legs 100, which will not be elaborated here.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
