Description

Technical Field

[0001] This utility model relates to the field of stainless steel bed technology, and in particular to an improved stainless steel bed with an improved connection structure. Background Technology

[0002] Traditional stainless steel beds are prone to displacement during installation when the nuts and bolts are connected, which affects the stability of the connection between the bolts and nuts and thus the overall stability of the stainless steel bed.

[0003] To increase the stability of the screw, existing stainless steel beds use a socket structure. An elastic structure is added to the outer side of the screw inside the joint. This elastic structure abuts against the screw, guiding and stabilizing it, while also buffering the vibration of the bed, thus enhancing the stability of the stainless steel bed. However, the connection structure of existing stainless steel beds mostly adopts a female-female socket structure. Single beds usually use 4 female-female sockets, and double beds use 8. Each female-female socket is fixed by 2 screws.

[0004] For example, patent application number "202122469631.6" entitled "A Stable Socket-Type Environmentally Friendly Stainless Steel Bed" discloses a connection structure for a stainless steel bed. This stainless steel bed includes a headboard, a footboard, a stainless steel connector, a main beam, and a secondary beam. One side of the main beam is welded to one side of the headboard via a stainless steel connector, and the other side of the main beam is welded to one side of the footboard via a stainless steel connector. The connection between the two ends of the main beam is achieved through the stainless steel connector and a second screw. A rotating block is hinged to the inner wall of the stainless steel connector near the second screw hole. Return springs are fixedly connected to the inner walls of both the upper and lower ends of the stainless steel connector. Sliding rods are fixedly connected to the inner walls of both ends and on both sides of the return spring. A sliding plate is fixedly connected to the side of the return spring away from the inner wall of the stainless steel joint. The sliding plate has a sliding hole for the sliding rods to slide through. A fixing post is fixedly connected to the outer wall of one side of the sliding plate. A strip-shaped sliding hole is opened on the side of the rotating block away from the inner wall of the stainless steel joint. The outer wall of the fixing post is slidably connected to the inner wall of one side of the strip-shaped sliding hole. An arc-shaped limiting block is fixedly connected to the side of the sliding plate away from the return spring. The side of the nut near the arc-shaped limiting block is set as an inclined surface. That is, this patent increases the stability of the screw by using the elastically set arc-shaped limiting block to abut against the screw. However, this structure has shortcomings:

[0005] 1. Refer to the appendix of this patent. Figure 3 Appendix Figure 4 The stainless steel joint has two screw holes and is connected by two screws. Because the two screw holes are linearly distributed, the stress on the stainless steel joint is too concentrated. After long-term use, the screws will loosen due to stress concentration. The anti-torsion ability is weak. When the bed is subjected to large forces and vibrates up and down, it is easy to loosen due to insufficient force.

[0006] 2. The installation of stainless steel joints and bolt holes in the main beam requires high precision; deviations can easily occur, causing inconvenience in installation.

[0007] 3. Stainless steel joints use a simple steel plate structure with poor rigidity and strength, and will deform under high stress. Utility Model Content

[0008] The purpose of this utility model is to solve the above-mentioned technical problems and provide a stainless steel bed with an improved connection structure. The joint of the stainless steel bed adopts a structure with three or four screw holes for uniform stress distribution, which enhances the torsional resistance. In addition, the inner wall of the joint is reinforced with reinforcing ribs that match the arrangement of the screw holes, resulting in high structural strength and convenient installation.

[0009] To solve the aforementioned problems in the prior art, the technical solution of this utility model is as follows:

[0010] This utility model discloses an improved stainless steel bed with a connection structure. It includes uprights at both ends of the bed frame, two large beams set in the middle of the uprights, and multiple small beams longitudinally connected in the middle of the large beams. The two ends of the large beams are connected to the uprights by stainless steel joints. One side of the stainless steel joint is welded to the upright, and the other side is connected to the large beam by a socket joint structure. The socket joint structure is fixed by bolts.

[0011] As an improvement, the stainless steel joint is a square tubular structure. The inner wall of the square tubular structure is formed with three or four joint screw holes arranged in a stable pattern. The two ends of the main beam are respectively formed with three or four main beam screw holes arranged in a stable pattern and matching the joint screw holes. The inside of the square tubular structure is welded with three or four nuts that match the joint screw holes. The main beam is inserted into the stainless steel joint, and the connection between the main beam and the column is achieved by rotating the bolts through the main beam screw holes, joint screw holes, and nuts. The bolts are arranged in a stable triangular or quadrilateral shape. The stainless steel joint is evenly stressed and has strong torsional resistance, and the bed frame can withstand greater vertical vibration.

[0012] As an improvement, the inner surface of the inner wall of the square tubular structure is formed with triangular or quadrangular reinforcing ribs that match the screw holes of the joint, further enhancing the rigidity of the stainless steel joint, making it more resistant to deformation under stress.

[0013] As an improvement, the bolt holes in the main beam are strip-shaped or elliptical holes, which facilitates installation.

[0014] This utility model discloses an improved stainless steel bed with a connection structure, which has the following advantages:

[0015] 1. The joints of this stainless steel bed adopt a three- or four-screw-hole structure with even stress distribution to enhance torsional resistance;

[0016] 2、 and the inner wall of the joint increases the reinforcing rib matched with the arrangement of the screw holes, and the structural strength is large;

[0017] 3、 and convenient installation. BRIEF DESCRIPTION OF DRAWINGS
