Description

Technical Field

[0001] This utility model relates to the field of fixed bed frames, and more specifically, to a simple connecting device for supporting fixed bed frames. Background Technology

[0002] A bed frame refers to a structure that makes up a bed. To ensure the overall stability of the bed frame, support components are usually used between the support legs and the bed board to provide auxiliary support and improve the stability. Most existing support components use a separate support leg added in the middle of the bed board for fixation, or use an inclined plate between the support leg and the bed board. However, the distance and angle of the inclined plate are often fixed and cannot be adjusted.

[0003] In existing technologies, the angle and distance between the added inclined plate and the bed board and support legs cannot be effectively adjusted, which limits the overall support capacity of the bed frame and makes it unable to meet different pressure requirements. Furthermore, the support components cannot adapt to the installation requirements of fixed bed frames of different specifications, further reducing the practicality of the original inclined plate support. Therefore, there is a need for a support component that can be detached from the bed frame and whose length can be easily and conveniently adjusted. Utility Model Content

[0030] Example 1:

[0031] Please see Figure 1-5 A simple connecting device for supporting and fixing a bed frame includes a fixed bed frame 1, a support leg 2 fixedly installed at the bottom end of the fixed bed frame 1, a first support component 3 fixedly installed on the side of the support leg 2, a second support component 4 movably installed on the surface of the first support component 3, and a fixed assembly component 5 movably installed on the top end of the second support component 4. The fixed assembly component 5 includes a guide rail 501, a sliding groove 502 is formed inside the bottom surface of the guide rail 501, a guide rod 503 is fixedly installed inside the sliding groove 502, and protruding plates 504 are fixedly installed on both the front and rear sides of the top surface of the guide rail 501. The surface of the protruding plate 504 is formed with a threaded groove 505.

[0032] It should be noted that the support leg 2 and the fixed bed frame 1 in this application are both existing mature technologies. The fixed connection between the first support component 3 and the support leg 2, especially the mounting frame 302 and the support leg 2, can be fixed by using existing sheet metal parts and bolts. This is an existing mature technology, so it will not be elaborated on in this application.

[0033] A bolt is installed inside the threaded groove 505. The top of the bolt is threadedly connected to the bottom surface of the fixed bed frame 1. The second support component 4 includes a U-shaped connecting frame 1 401. A U-shaped connecting frame 2 402 is movably sleeved on the surface of the U-shaped connecting frame 1 401. A fixing ring 403 is fixedly installed on the inner wall of the U-shaped connecting frame 2 402. A rotating ring 404 is rotatably installed inside the fixing ring 403. A rotating frame 405 is rotatably installed on the top of the U-shaped connecting frame 2 402. A sliding block 406 is fixedly installed on the top of the rotating frame 405. A spring 407 is fixedly connected to both ends of the sliding block 406. The sliding block 406 is slidably installed inside the sliding groove 502, and the two are matched in shape. The outer ends of the two springs 407 are respectively fixedly connected to the left and right sides of the inner wall of the guide rail 501. The sliding block 406 is movably sleeved on the surface of the guide rod 503.

[0034] Specifically, the support component and the fixed bed frame 1 are separated by disassembly and assembly through the threaded groove 505, bolts, and fixed bed frame 1. The sliding groove 502 and sliding block 406 are matched to achieve the limited movement between the two. The guide rod 503 is used to achieve the support effect. Finally, the spring 407 can apply pressure on both sides during the sliding of the sliding block 406 to further improve its movement stability and prevent excessive pressure on the guide rod 503 from causing wear and deformation.

[0035] The first support assembly 3 includes a connecting plate 301, a mounting bracket 302 is rotatably mounted inside the connecting plate 301, a ring 303 is fixedly mounted on the top of the connecting plate 301, a screw 304 is fixedly mounted on the outer wall of the ring 303, the ring 303 and the bottom end of the U-shaped connecting bracket 401 are rotatably connected to each other, the mounting bracket 302 is fixedly mounted on the side of the support leg 2, and the screw 304 and the rotating ring 404 are threadedly connected to each other.

[0036] Specifically, the fixed ring 403 and the rotating ring 404 are rotatably connected to each other to ensure that they can rotate in a limited position, thus ensuring that the rotating ring 404 rotates in its original position. Then, with the help of the screw 304, the distance between the U-shaped connecting frame 1 401 and the U-shaped connecting frame 2 402 can be moved, which facilitates the distance movement during adjustment. Furthermore, the rotatable connection between the bottom end of the U-shaped connecting frame 1 401 and the ring 303, as well as the rotatable connection between the rotating frame 405 and the U-shaped connecting frame 2 402, ensure that there will be no mutual repulsion of movement caused by the fixed angle when the distance between the U-shaped connecting frame 1 401 and the U-shaped connecting frame 2 402 is adjusted, thus further improving the practicality of the overall device.

[0037] The working principle of this utility model is as follows: the convex plate 504 is fixed to the bottom surface of the fixed bed frame 1 through the threaded groove 505 and bolts, and then the mounting bracket 302 is fixed to the side of the support leg 2. Then, according to the length specifications of the fixed bed frame 1, the U-shaped connecting bracket 1 401 and U-shaped connecting bracket 2 402 are adjusted to a suitable distance. If the fixed bed frame 1 is too long, the rotating ring 404 is rotated to drive the screw 304 to transmit power, so that the U-shaped connecting bracket 2 402 moves as the position of the fixed ring 403 and the rotating ring 404 changes, and it extends with the U-shaped connecting bracket 1 401. Then, the sliding block 406 slides to the right along the guide rod 503 inside the sliding groove 502, and compresses and stretches the two springs 407 accordingly until the overall length of the U-shaped connecting bracket 1 401 and U-shaped connecting bracket 2 402 matches the required support length of the fixed bed frame 1.

[0038] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
