[0052] Second embodiment
[0053] As Figure 2As shown in the second embodiment of the utility model is a bed frame. The bed frame comprises a corner connecting and fixing structure of the second embodiment of the utility model. As shown in Figures 3 to 7 As shown in the second embodiment of the utility model is a corner connecting and fixing structure. The bed frame comprises a corner connecting and fixing structure. The corner connecting and fixing structure comprises a horizontal frame 101 as a first component 100, a vertical frame 201 as a second component 200, and a corner fixing assembly 300. Cooperate with one of the bed boards, the horizontal frame 101 is provided with two, which is processed from steel profile. The vertical frame 201 is also provided with two, which is also processed from steel profile. Each horizontal frame 101 and each vertical frame 201 are connected at a right angle, and are provided with a corner fixing assembly 300 for fixing. The corner fixing assembly 300 comprises a first corner code 310, a second corner code 320 and a fastener 330. The first corner code 310 and the second corner code 320 are processed from sheet metal.
[0054] Specifically, as shown in Figures 4 to 6 The first corner code 310 is provided with a first connecting plate 312 as a first pair of side parts 311. The front and back sides of the first connecting plate 312 are respectively provided with a first supporting plate 313. Optionally, the first supporting plate 313 is in triangular shape, and has at least an adjacent side cooperating with the side wall of the horizontal frame 101. To adapt to the vertical frame 201 and the horizontal frame 101 installed at right angles, the first supporting plate 313 is in right triangle shape. In order to provide fastening points and facilitate installation, the first connecting plate 312 is configured as the hypotenuse of the isosceles right triangle, and the first supporting plate 313 is in isosceles right triangle shape. The first supporting plate 313 and the horizontal frame 101 can be connected by welding, realizing the connection of the first corner code 310 and the horizontal frame 101. The welding position of the first connecting plate 312 and the horizontal frame 101 is arranged at an angle. It can be understood that the two first supporting plates 313 are also used for supporting the first connecting plate 312 and increasing the strength of the first connecting plate 312.
[0055] It is worth mentioning that the first corner code 310 can be welded on site in the construction site with welding conditions. For this purpose, the first support plate 313 is provided with a plurality of positioning protrusions 314 on the side connected to the first component 100, and the horizontal frame 101 is provided with a plurality of positioning holes 110 that can accommodate the positioning protrusions 314 by cutting. Before welding, the four positioning protrusions 314 on the first corner code 310 are assembled into the four positioning holes 110 of the horizontal frame 101, and then welding is performed along the outer contour of the contact between the first support plate 313 of the first corner code 310 and the horizontal frame 101, thereby improving the strength of the connection. In other sites without welding conditions, the first corner code 310 can also be pre-welded to the horizontal frame 101. Those skilled in the art can understand that the end of the vertical frame 201 abuts against the side wall of the horizontal frame 101 near the end, and the connection position of the first corner code 310 and the horizontal frame 101 will reserve the abutting position of the end of the vertical frame 201.
[0056] Specifically, as shown in Figure 4 、 Figure 5 and Figure 7 , the second corner code 320 is provided with a second connecting plate 322 as a second pair of side portions 321. The front and rear sides of the second connecting plate 322 are respectively provided with second support plates 323. Optionally, the second support plate 323 is triangular in shape and has at least an adjacent side cooperating with the side wall of the vertical frame 201. To adapt to the vertical frame 201 and the horizontal frame 101 installed at right angles, the second support plate 323 is in the shape of a right triangle. In order to provide fastening points and facilitate installation, the second connecting plate 322 is configured as the hypotenuse of an isosceles right triangle, and the second support plate 323 is in the shape of an isosceles right triangle. In order to make the second corner code 320 arranged outside the first corner code 310, the length of the second connecting plate 322 is greater than the length of the first connecting plate 312. In addition, the width of the second connecting plate 322 is also greater than the width of the first connecting plate 312, so that the two second support plates 323 are sleeved outside the two first support plates 313.
[0057] It is worth mentioning that, since the first connecting plate 312 of the first corner code 310 has provided a fastening point for the horizontal frame 101, the second corner code 320 can be constrained by a clamping bit or the like in a lower connecting manner, thereby reducing the difficulty of assembly. For this purpose, the two ends of the second connecting plate 322 are provided with second clamping plates 324, the horizontal frame 101 is provided with clamping holes 210, and the vertical frame 201 is provided with clamping holes 210. When the second corner code 320 is connected to the first corner code 310 by the fastener 330 in a manner of approaching each other, the second corner code 320 is tightly clamped in the clamping holes 210 of the vertical frame 201 by the second clamping plates 324 at the lower end of the second connecting plate 322, thereby realizing the connection of the second corner code 320 and the vertical frame 201. In order to increase the strength of the corner connection, the second corner code 320 is also tightly clamped in the clamping holes 210 of the horizontal frame 101 by the second clamping plates 324 at the upper end of the second connecting plate 322, thereby increasing the point of fastening contact.
[0058] As can be understood by those skilled in the art, when the horizontal frame 101 and the vertical frame 201 are connected, the first connecting plate 312 and the second connecting plate 322 are parallel to each other, and the bolt 331 and the nut 332 can better exert the fastening force. In order to realize the parallelism of the first connecting plate 312 and the second connecting plate 322, the included angle between the first connecting plate 312 and the horizontal frame 101 and the included angle between the second connecting plate 322 and the vertical frame 201 are complementary angles. In the embodiment, the preset assembly angle is 90°, the included angle between the first connecting plate 312 and the horizontal frame 101 is 45°, and the included angle between the second connecting plate 322 and the vertical frame 201 is 45°.
[0059] Further, in the construction site with welding conditions, the contact outer contour of the second supporting plate 323 of the second corner code 320 and the vertical frame 201 can be welded, thereby improving the connection strength. As can be understood by those skilled in the art, the welding of the second corner code 320 and the vertical frame 201, and the clamping constraint of the second corner code 320 and the horizontal frame 101 do not affect the disassembly of the vertical frame 201 and the horizontal frame 101 later.
[0060] In order to facilitate assembly operation, the end of the vertical frame 201 is provided with a buckle 220, the side wall of the horizontal frame 101 is provided with a clamping hole 120, and the buckle 220 and the clamping hole 120 cooperate with each other to clamp and connect the vertical frame 201 and the horizontal frame 101. In the assembly process, after the vertical frame 201 and the horizontal frame 101 are clamped and connected, the second clamping plates 324 at both ends of the second corner code 320 can be respectively installed into the clamping holes 210 of the horizontal frame 101 and the vertical frame 201, thereby further facilitating the installation of the fastener 330.
[0061] It can be understood that the fastener 330 of the utility model can be riveted, bolted 331 connected and the like in multiple ways. In each embodiment of the utility model, the fastener 330 is a bolt 331 and a nut 332. The nut 332 is fixedly arranged on the first connecting plate 312, the bolt 331 passes through the second connecting plate 322 and is fixed with the nut 332 on the first connecting plate 312, so that the first pair of edge portions 311 and the second pair of edge portions 321 are fixedly connected in the direction of approaching each other. In the assembly process, the bolt 331 is mounted on the nut 332 on the first connecting plate 312 from the direction of the right angle center line, has a large construction space, and can be quickly installed by means of an electric screwdriver.
[0062] It is worth supplementing that the bed frame of the second embodiment further comprises a reinforcing beam 400, which is composed of a middle section and a bending section arranged on the middle section and bent towards the same side. The middle section of the reinforcing beam 400 is connected to the horizontal frame 101 by screws, and the ends of the bending section of the reinforcing beam 400 are respectively welded to the longitudinal frames 201 on both sides, thereby further improving the strength of the corner connection.
[0063] The above embodiments mainly describe the basic principles, main features and advantages of the utility model. It should be understood by those skilled in the art that the utility model is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the utility model.
