Description

Technical Field

[0001] This utility model relates to the field of bed connection structures, and in particular to a connection structure and a bed. Background Technology

[0002] The bed, an indispensable part of home life, has long transcended the mere provision of a good night's sleep. It not only embodies comfort and enjoyment but also creates a warm and relaxing private space. After sufficient rest, people can devote more energy to their studies or work. With the continuous improvement of living standards, the styles and functions of beds are constantly innovating, from traditional single beds to multi-functional beds, meeting people's increasingly diverse needs.

[0003] However, in the manufacturing and assembly of beds, traditional support connections mostly rely on welding. The surfaces of welded structural components often suffer from numerous problems: weld slag residue, uneven welds, incomplete welds, and burn-through are common, severely impacting the product's appearance and texture. To remedy these defects, manual secondary processing is often required, including tedious procedures such as cleaning surface residue, repair welding, and grinding. Even after painting, these structural components may still experience paint peeling and rusting under different usage environments. Over time, corrosion gradually penetrates the metal, leading to structural component cracking and breakage. Under long-term heavy loads, these problems can eventually cause the bed to collapse, posing a significant safety hazard to users. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes a connection structure that enables quick and stable installation of hanging parts, with the connection point hidden inside the column for a more aesthetically pleasing appearance.

[0005] This utility model also proposes a bed having the above-mentioned connection structure.

[0006] On one hand, the connection structure according to the embodiment of this utility model includes:

[0007] The column includes a first bending surface, the first bending surface is provided with a first bending part and a second bending part, the first bending part and the second bending part are staggered in both longitudinal and transverse directions, and both the first bending part and the second bending part are provided with positioning holes;

[0008] The pendant includes a second bent surface, the second bent surface is provided with a third bent portion and a fourth bent portion, the third bent portion and the fourth bent portion are spaced apart in both the longitudinal and transverse directions, and both the third bent portion and the fourth bent portion are provided with a buckle;

[0009] After the hanger is attached to the column, the first bent surface can cooperate with the second bent surface, and the buckle can be attached to the corresponding positioning hole.

[0010] According to some embodiments of the present invention, one of the first bending portion and the second bending portion is located at the inner corner of the first bending surface, and the other is located at the outer corner of the first bending surface; one of the third bending portion and the fourth bending portion is located at the outer corner of the second bending surface, and the other is located at the inner corner of the second bending surface.

[0011] According to some embodiments of the present invention, the first bending portion and the second bending portion are both located at the inner or outer corner of the first bending surface, and the third bending portion and the fourth bending portion are both located at the outer or inner corner of the second bending surface.

[0012] According to some embodiments of this utility model, a support portion and a snap-fit ​​portion extend sequentially from the side of the second bending surface near the first bending surface to form the buckle. After the hanging piece is attached to the column, the support portion can abut against the inner wall of the positioning hole, and the snap-fit ​​portion can abut against the side of the first bending surface away from the second bending surface.

[0013] According to some embodiments of the present invention, the snap-fit ​​portion is provided with a curved surface that mates with the corresponding first bent portion or second bent portion.

[0014] According to some embodiments of the present invention, the first bending surface is further provided with a plurality of fifth bending portions, and the second bending surface is further provided with a plurality of sixth bending portions, wherein the plurality of fifth bending portions and the plurality of sixth bending portions are provided in a one-to-one correspondence.

[0015] According to some embodiments of the present invention, the column is further provided with a plurality of positioning holes arranged in the vertical direction.

[0016] According to some embodiments of the present invention, the hanging component is further provided with a plurality of buckles arranged in the vertical direction, and the column is further provided with a plurality of positioning holes arranged in the vertical direction, the number of positioning holes arranged in the vertical direction corresponding to the number of buckles arranged in the vertical direction.

[0017] According to some embodiments of the present invention, the hanger further includes a crossbeam, and two second bending surfaces are respectively disposed at both ends of the crossbeam.

[0018] According to some embodiments of the present invention, a locking member is also included. The first bent surface is provided with a first locking hole, and the second bent surface is provided with a second locking hole. The locking member can pass through the first locking hole and the second locking hole to fix the first bent surface and the second bent surface relative to each other.

[0019] On the other hand, the bed according to the present invention includes the connection structure according to the above embodiments of the present invention.

[0020] The embodiments of this utility model have at least the following beneficial effects:

[0021] The hangers can be directly and quickly attached to the posts, simplifying the installation process and significantly improving construction efficiency.

[0022] After connection, the first and second bent surfaces fit tightly together. Crucially, there are gaps both longitudinally and laterally between the first and second bent sections, as well as between the third and fourth bent sections. This arrangement ensures that the contact area between the two bent surfaces is not a single plane, but rather distributed across different planes with spatial angles. This creates a spatial complementary force system: this design of intersecting longitudinal and lateral mating surfaces significantly increases the effective contact area between the two surfaces. More importantly, it forms a mutually restrictive and synergistic mechanical relationship (i.e., a complementary force system) in multiple directions, significantly improving the connection structure's ability to resist loads in all directions and ensuring overall stability after installation.

[0023] Multi-point coordinated locking: The buckles are respectively hooked into the positioning holes on the first and second bends, located at different spatial positions (determined by the longitudinal and transverse spacing). This multi-point, non-collinear hooking method ensures that the constraint forces generated by each buckle mutually support and balance each other in space, effectively preventing the hanger from loosening, twisting, or slipping relative to the column, greatly improving the stability and resistance to deformation during installation. The engagement method between the buckles and the positioning holes is intuitive and straightforward, making operation simple. At the same time, the longitudinal and transverse spacing settings also implicitly provide a precise positioning reference, helping to ensure the consistency of the installation position.

[0024] The installation positions are all inside the uprights, close to the inside of the bed, and are not exposed on the outside. The hooks and screws are not visible from the outside.

[0025] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0042] Reference Figures 1-5 The basic embodiment of the first aspect of this utility model provides a connection structure, including:

[0043] The column 100 includes a first bending surface 110, the first bending surface 110 is provided with a first bending part 111 and a second bending part 112, the first bending part 111 and the second bending part 112 are spaced apart in both the longitudinal and transverse directions, and both the first bending part 111 and the second bending part 112 are provided with positioning holes 120.

[0044] The pendant 200 includes a second bending surface 210, the second bending surface 210 is provided with a third bending part 211 and a fourth bending part 212, the third bending part 211 and the fourth bending part 212 are staggered in both the longitudinal and transverse directions, and both the third bending part 211 and the fourth bending part 212 are provided with a buckle 220.

[0045] After the hanger 200 is attached to the column 100, the first bending surface 110 can cooperate with the second bending surface 210, and the buckle 220 can be attached to the corresponding positioning hole 120.

[0046] According to embodiments of this utility model, this configuration achieves at least the following effects: the hanger 200 can be directly and quickly attached to the column 100, simplifying the installation process and significantly improving construction efficiency. After attachment, the first bending surface 110 and the second bending surface 210 fit tightly together. Crucially, the first bending portion 111 and the second bending portion 112, as well as the third bending portion 211 and the fourth bending portion 212, have spacing in both the longitudinal and transverse directions. This layout ensures that the contact area between the two bending surfaces is not a single plane, but rather distributed across different planes with spatial angles. This creates a spatial complementary force system: this longitudinally and transversely intersecting mating surface design greatly increases the effective contact area between the two surfaces. More importantly, it forms a mutually restrictive and synergistic mechanical relationship (i.e., a complementary force system) in multiple directions, significantly improving the connection structure's ability to resist loads in all directions and ensuring overall stability after installation. Multi-point coordinated locking: The latches 220 are respectively hooked into the positioning holes 120 on the first bend 111 and the second bend 112, which are located at different spatial positions (determined by the longitudinal and transverse spacing). This multi-point, non-collinear hooking method ensures that the constraint forces generated by each latch 220 mutually support and balance each other in space, effectively preventing the hanger 200 from loosening, twisting, or slipping relative to the column 100, greatly improving the stability and resistance to deformation during installation. The engagement method between the latches and the positioning holes 120 is intuitive and easy to operate. At the same time, the longitudinal and transverse spacing settings also implicitly provide a precise positioning reference, which helps to ensure the consistency of the installation position. The installation positions are all inside the column 100, close to the inside of the bed, and are not exposed on the outside, so the hooks and screws are not visible from the outside.

[0047] It should be noted that both the first and second bending surfaces undergo at least two bends to form at least two bends. The bends can be located at any of these bends, meaning the corresponding positioning holes and buckles can be placed at any of the bends. The positioning holes and buckles can be interchanged; that is, the positioning holes can be placed on the hanger, and the buckles can be placed on the column, with the same effect.

[0048] It should be noted that misalignment refers to the misalignment of mechanical parts or mechanisms in spatial position, that is, there is a gap in the longitudinal and lateral positions, forming a certain positional deviation. Both "longitudinal" and "lateral" gaps refer to the spatial relationship relative to the horizontal installation reference plane.

[0049] Longitudinal spacing: refers to the distance formed by the difference in front-to-back position of the first bend 111 and the second bend 112 in the horizontal direction.

[0050] Lateral spacing: refers to the distance formed by the difference in left and right positions of the first bend 111 and the second bend 112 in the horizontal plane.

[0051] This spacing, set in two orthogonal dimensions of space, is the core design element to ensure that the first bending surface 110 and the second bending surface 210 can form an effective spatial angle, generate multi-directional complementary constraint force, and realize the multi-point collaborative locking function of the buckle 220 when they are engaged.

[0052] In a first implementation, in some embodiments, the first bending portion 111 and the second bending portion 112 are respectively located at the inner corner of the first bending surface 110 and the other at the outer corner of the first bending surface 110. Similarly, the third bending portion 211 and the fourth bending portion 212 are respectively located at the outer corner of the second bending surface 210 and the other at the inner corner of the second bending surface 210. By placing the first bending portion 111 and the second bending portion 112 at the inner and outer corners of the first bending surface 110 (the third bending portion 211 and the fourth bending portion 212 are mirror-symmetrical to this), a spatially staggered layout is formed. When the hanger 200 is attached: the buckle 220 at the inner corner engages with the positioning hole 120 to generate an inward restraining force, resisting lateral displacement; the buckle 220 at the outer corner engages with the positioning hole 120 to generate an outward restraining force, resisting longitudinal displacement; the force systems at the inner and outer corners together constitute a spatial torque balance, significantly suppressing the risk of loosening.

[0053] In a second implementation, in some embodiments, the first bend 111 and the second bend 112 are both located at the inner or outer corner of the first bend surface 110, and the third bend 211 and the fourth bend 212 are both located at the outer or inner corner of the second bend surface 210. By uniformly setting the first bend 111 and the second bend 112 at the inner or outer corner (with the third bend 211 and the fourth bend 212 corresponding to them), a spatial coplanar layout of the buckle 220 is achieved: during installation, only alignment in one direction is required, simplifying the positioning process; during disassembly, constraints can be released through a single direction of force, improving maintenance efficiency; suitable for scenarios with low load-bearing strength requirements and frequent disassembly and assembly.

[0054] It should be noted that the setting of the inner angle and the outer angle is based on the side that is in contact with the first bending surface 110 and the second bending surface 210. The inner angle refers to the concave part and the outer angle refers to the convex part. The inner angle of the first bending surface 110 can be matched with the outer angle of the second bending surface 210, and the outer angle of the first bending surface 110 can be matched with the inner angle of the second bending surface 210.

[0055] In some embodiments, a support portion 221 and a locking portion 222 extend sequentially from the side of the second bending surface 210 near the first bending surface 110 to form a buckle 220. After the hanger 200 is attached to the column 100, the support portion 221 can abut against the inner wall of the positioning hole 120, and the locking portion 222 can abut against the side of the first bending surface 110 away from the second bending surface 210. The buckle 220 adopts a three-section mechanical design: the support portion 221 abuts against the inner wall of the positioning hole 120, bears the main vertical load, and prevents sinking; the locking portion 222 hooks onto the back of the first bending surface 110, provides a reverse locking force, and resists disengagement.

[0056] In some embodiments, the snap-fit ​​portion 222 is provided with a curved surface that mates with the corresponding first bend portion 111 or second bend portion 112. The curved surface design of the snap-fit ​​portion 222 matches the contour of the bend portion, achieving: surface-to-surface contact instead of point contact, dispersing local stress and avoiding plastic deformation; adaptive tolerance compensation, allowing installation angle deviation within ±1°; and micro-friction self-locking effect, suppressing micro-displacement caused by vibration or impact.

[0057] In some embodiments, the first bending surface 110 is further provided with a plurality of fifth bending portions, and the second bending surface 210 is further provided with a plurality of sixth bending portions, with the plurality of fifth bending portions and the plurality of sixth bending portions being arranged one-to-one. By adding the fifth bending portions (first bending surface 110) and the sixth bending portions (second bending surface 210): the load path is linearly extended, transforming single-point bearing into distributed bearing; redundant constraint design ensures high connection strength even when a single buckle 220 fails; and it adapts to heavy-duty suspension requirements, with each additional pair of bending portions increasing the anti-overturning moment.

[0058] In some embodiments, the column 100 is further provided with a plurality of positioning holes 120 arranged in the vertical direction. Depending on different needs, the height of the hanger 200 can be adjusted by installing the hanger 200 on the positioning holes 120 at different heights.

[0059] In some embodiments, the hanger 200 is further provided with a plurality of buckles 220 arranged in the vertical direction, and the column 100 is further provided with a plurality of positioning holes 120 arranged in the vertical direction. The number of positioning holes 120 arranged in the vertical direction corresponds to the number of buckles 220 arranged in the vertical direction. The hanger 200 is provided with a plurality of buckles 220 arranged in the vertical direction, which increases the number of buckles 220 and improves the installation reliability.

[0060] In some embodiments, the hanger 200 further includes a crossbeam 230, with two second bending surfaces 210 respectively disposed at both ends of the crossbeam 230.

[0061] In some embodiments, both the first bending surface 110 and the second bending surface 210 form right-angle bending structures after bending. The advantages of the right-angle bending design are: maximized moment of inertia of the cross-section, resulting in a ≥40% increase in bending stiffness compared to a 45° bend; and standardized molds, making it suitable for continuous roll forming and reducing manufacturing costs.

[0062] In some embodiments, a locking element is also included. The first bent surface 110 has a first locking hole, and the second bent surface 210 has a second locking hole 213. The locking element can pass through the first locking hole and the second locking hole to fix the first bent surface 110 and the second bent surface relative to each other. Fixing the first bent surface 110 and the second bent surface 210 by the locking element can play a reinforcing role and improve installation stability. The locking element can be a pin or a bolt.

[0063] It should be noted that in this specification, terms such as "one embodiment", "some embodiments", "basic embodiment", and "extended embodiment" may be used to describe several embodiments of the present invention, and the specific features, structures, materials or characteristics of the several embodiments may be combined in accordance with the principles and spirit of the present invention.

As long as they achieve the technical effects of the present utility model by the same or equivalent means, any changes, modifications, equivalent substitutions and equivalent variations of these embodiments within the spirit and principles disclosed in the present utility model, without departing from the principles and purpose of the present utility model, should be included within the scope of protection disclosed in the present utility model and should be considered to fall within the protection scope of the present utility model.
