AI Technical Summary
The existing bed frame's snap-fit structure is prone to loosening, resulting in frame instability, noise during use, and a lack of fastening measures.
The design employs a hook-and-loop mechanism on the card plate. The hook's base extends smoothly upwards from both sides to the center and protrudes outwards to form a root protrusion. The vertical beam has a locking hole. After the hook is inserted into the locking hole, the outer surface of the card plate presses against the outer plane of the vertical beam. The locking force of the hook is evenly transmitted to the root protrusion, increasing the resistance to deformation and tearing. The structural stability is further enhanced by longitudinal ribs and anti-detachment protrusions.
This design achieves a tight connection between the bed frames, improving structural stability and resistance to deformation, preventing loosening, making it flexible and convenient to use, and reducing noise generation.

Detailed Implementation
[0025] refer to Figures 2 to 9 As shown, a novel connection structure for a bed frame is presented, including a vertical beam 1 and a horizontal beam 2. The end of the horizontal beam 2 is sealed with a retaining plate 3. The retaining plate 3 has a downward-opening hook 31 protruding from it. The root of the hook 31 extends smoothly upward from both sides to the middle and protrudes outward to form a root protrusion 32. The vertical beam 1 has a retaining hole 11 for holding the retaining plate 3.
[0026] As attached Figure 1 As shown, the base of a common downward-opening latch is usually a straight structure, which easily leads to stress concentration and insufficient resistance to deformation. (See attached image) Figures 2 to 9As shown, the clamping plate 3 is arranged at the end of the cross beam 2, and the clamping hook 31 on the clamping plate 3 protrudes outward and is bent downward, and the inner wall of the clamping hook 31 and the outer plane of the clamping plate 3 form a clamping groove 311 which is convenient for clamping into the clamping hole 11 on the side of the vertical beam 1. After clamping, the outer surface of the clamping plate 3 abuts against the outer plane of the vertical beam 1 to form a tight clamping. The other end of the cross beam 1 is tightly clamped with the corresponding vertical beam 1 in the same way, so that the cross beam 1 can be further clamped between the front and rear vertical beams 1. The clamping root of the clamping hook 31 is not flat, but smoothly extends upward from both sides to the middle, that is, the longitudinal thickness from the middle to both sides is thicker, and the local strength is better. When the thickened clamping root is clamped against the lower edge of the clamping hole 11 upward, the two sides of the clamping hook 31 abut against the lower edge of the clamping hole 11, and the clamping force is uniformly transmitted to the entire root protrusion 32 which is smoothly transitioned. At the same time, due to the overall outward protrusion of the root protrusion 32, the stress concentration of the root protrusion 32 can be greatly reduced, and the anti-deformation and anti-tear strength of this part can be increased. This clamping structure can be used at any position of the bed frame that needs to be connected, including the connection between two bed frames, etc., and is flexible and convenient to use.
[0027] Further, the clamping plate 3 is a thin plate member, and the clamping hook 31 is formed by a punching opening 33 which is partially punched on the clamping plate 3 to form a three-edge opening. The middle of the clamping hook 31 is smoothly punched outward to form a longitudinal rib 34.
[0028] As shown in the drawings, the clamping plate 3 is made of a thin plate material, for example, a stainless steel plate. A left, right and bottom three-edge opening punching opening 33 is punched from the inside to the outside on the clamping plate 3. The upper edge of the punching opening 33 is connected with the clamping plate 3, and the punching opening 33 is formed by punching to protrude outward and smoothly transition from the middle upward and both sides downward to form a root protrusion 32. The clamping hook 31 is formed by extending downward from the root protrusion 32, and the inner wall of the clamping hook 31 and the outer plane of the clamping plate 3. In the middle of the clamping hook 31, a longitudinal rib 34 is further punched outward from the inside to the outside, that is, the thickness between the middle longitudinal rib 34 of the clamping hook 31 and both edges is thickened, so as to further increase the structural strength of the main body of the clamping hook 31, and prevent the clamping hook 31 from being deformed and folded outward under the action of external force.
[0029] Further, the inner side of both edges of the clamping hook 31 is provided with a smoothly transitioned anti-disengagement protrusion 35.
[0030] As shown in the drawings, the anti-disengagement protrusion 35 is located in the middle of the clamping hook 3, and is respectively arranged on the inner side of the edge of both sides of the clamping hook 3, so that the width of the clamping groove 311 is reduced at this position. When the clamping hook 31 of the thin plate member is clamped into the clamping hole 11, the main body of the clamping hook 31 has a certain elasticity, and the upper edge of the clamping hole 11 can easily pass over the surface of the smoothly transitioned anti-disengagement protrusion 35 under the action of external force. After being in place, the anti-disengagement protrusion 35 can be elastically abutted against the outer surface of the vertical beam 1, so that the clamping structure is more stable and prevents loosening.
[0031] Further, the lower edge of the clamping hook 31 is outwardly bent to form a guide slope 36, which is smoothly connected with the anti-disengagement convex part 35.
[0032] As shown in the drawings, the lower edge of the clamping hook 31 includes a middle longitudinal rib 34 and two vertical edges on the sides, and the whole lower edge can be outwardly bent by a mold to form the outwardly bent guide slope 36, so that the clamping hook 31 is easier to be positioned and clamped into the clamping hole 11, and the guide slope 36 and the anti-disengagement convex part 35 are smoothly connected by the mold to form a continuous streamline contact between the inner side of the clamping hook 31 and the clamping hole 11, and the stress concentration of the clamping hook 31 is avoided to maintain the good strength.
[0033] Further, the clamping plate 3 is bent around to form an integrated cover 37.
[0034] As shown in the drawings, the cross beam 2 can be made of angle steel or other steel materials, and the clamping plate 3 can be a flat plate member blocked at the end of the cross beam 2, but the structure is more complex to process. In the embodiment, the clamping plate 3 is made into an independent component, which is bent around to form a hollow cover 37, and the cover 37 is integrally formed and has better strength.
[0035] Further, the cross beam 2 is a hollow square tube, and the cover 37 is embedded in the end of the cross beam 2.
[0036] As shown in the drawings, the cross beam 2 is a hollow square tube, which can be directly used as a standard component of a corresponding specification, and the processing is convenient and fast. The independent component cover 37 has an overall profile that is adapted to the cavity at the end of the cross beam 2, and can be directly embedded and welded to be fixed. This connection mode can support and fix the shape of the end of the cross beam 2 through the integrated cover 37, so that the overall strength of the end of the cross beam 2 is better.
[0037] Further, the clamping plate 3 has at least two clamping hooks 31 arranged longitudinally.
[0038] As shown in the drawings, the clamping plate 3 of the cover 37 has two clamping hooks 31 arranged vertically, and the cover 37 is embedded and fixed at the end of the cross beam 2, and the vertical beam 1 has two clamping holes 11 correspondingly, so that the two clamping hooks 31 can be clamped into the two clamping holes 11 at the same time, and the other end of the cross beam 2 is also the same, which can effectively prevent the cross beam 2 from rotating relative to the vertical beam 1, so that the bed frame is more stable.
[0039] Further, the cross beam 2 has welding holes 21 on both sides of the end, which correspond to the side walls of the embedded cover 37.
[0040] As shown in the drawings, for the convenience of fixing the cover 37 and the cross beam 2, welding holes 21 are formed in the corresponding positions of the cross beam 2 in advance, which can be used for positioning and welding the embedded cover 37, and the operation is simple and convenient.
