Description
Technical Field
[0001] This utility model relates to the field of bed frame inner corner fixing technology, and in particular to an open corner bracket for fixing the inner corner of a bed frame. Background Technology
[0002] An open corner bracket is a type of hardware used to connect components intersecting at 90-degree angles. It is typically L-shaped or T-shaped and has two or three connecting holes. It is made of various materials, including stainless steel, aluminum alloy, and carbon steel, with some undergoing hot-dip galvanizing for enhanced rust resistance. Primarily used to reinforce the inner corners of bed frames, it is fixed with screws to provide stability. Its advantages include easy installation, strong load-bearing capacity, and adaptability to humid environments. It is widely used for corner fixing in furniture such as bed frames, wardrobes, and workbenches, as well as in architectural decoration scenarios such as curtain wall installations. In upholstered beds and slatted bed frames, the open corner bracket features an adjustable design to accommodate different thicknesses of sheet metal.
[0003] However, traditional open corner brackets used for fixing the inner corners of bed frames have a relatively simple structure, a relatively outdated fixing method, and a relatively complicated operation. They require a high level of skill from the operators and are prone to inaccurate right-angle fixing, which may affect the use of the bed frame.
[0004] For example, traditional corner brackets used for fixing the inner corners of bed frames usually require the worker to use one hand to fix the bed frame to a right angle, and then use the other hand to place the corner bracket at the corner of the bed frame before fixing the corner bracket. This process is somewhat cumbersome. Utility Model Content
[0005] This utility model discloses an open corner bracket for fixing the inner corner of a bed frame, aiming to solve the technical problems of traditional open corner brackets for fixing the inner corner of a bed frame, which have a relatively simple structure, outdated fixing method, cumbersome operation steps, high requirements for operators, and are prone to inaccurate right-angle fixing angles, which may affect the use of the bed frame.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An open corner bracket for fixing the inner corner of a bed frame includes two first base frames and a second base frame disposed on one side of the two first base frames, and further includes:
[0008] Fixing mechanism: The fixing mechanism includes telescopic plates disposed between the two first base frames and the two second base frames. Square slots are provided on the outer walls of the opposite sides of the two first base frames and the two second base frames. The two telescopic plates are disposed inside the four square slots. Adapter slots are provided at equal intervals on one side of the outer walls of the two first base frames and the two second base frames. Two movable blocks are respectively provided on one side of the outer walls of the two telescopic plates. The four movable blocks are used in conjunction with the adapter slots.
[0009] Adjustment mechanism: The adjustment mechanism is mounted on the two first base frames.
[0010] In this solution, four L-shaped first and second base frames are combined to form two upward-opening U-shaped groove-shaped corner brackets. These, along with a retractable bottom plate, evenly spaced adapter slots, and two movable blocks, allow for easy placement of one of the first or second base frames on one side of the bed frame. Then, the other bed frame, requiring right-angle fixation, is placed into the U-shaped groove formed by the first and second base frames. The retractable plate is then adjusted to a suitable position to secure the bed frame firmly. This fixing method not only reduces the difficulty of fixing the corners of the bed frame but also avoids inaccurate right-angle fixing angles caused by manual adjustment through the right-angle design.
[0011] In a preferred embodiment, the adjustment mechanism includes elongated slots formed on the top outer walls of the two first base frames and the two second base frames. Each of the four elongated slots is provided with a first fixed shaft and a second fixed shaft. Each of the four first fixed shafts has two first connecting rods connected to its circumferential outer wall, and each of the four second fixed shafts has two second connecting rods connected to its circumferential outer wall.
[0012] By setting a first fixed shaft and a second fixed shaft between the two first base frames and the two second base frames, and cooperating with the first connecting rod and the second connecting rod, the two open corner brackets are connected into a whole. The spacing between them can be controlled by the first connecting rod and the second connecting rod. When installing the bed frame, the contact area with the bed frame is increased. Multiple open corner brackets can be connected by only one connector, which reduces the number of open corner brackets used and improves the fixing efficiency of the open corner brackets.
[0013] In a preferred embodiment, the two first links and the two second links are further connected by two connecting frames via bearings.
[0014] By using four connecting brackets between the two first links and the two second links, the two first links and the two second links can be easily fixed. At the same time, the bearing connection also avoids affecting the adjustment of the movement between the two first links and the two second links.
[0015] As described above, an open corner bracket for fixing the inner corner of a bed frame includes two first base frames and a second base frame disposed on one side of the two first base frames. It further includes: a fixing mechanism: the fixing mechanism includes telescopic plates disposed between the two first base frames and the two second base frames; square grooves are formed on the outer walls of opposite sides of the two first base frames and the two second base frames; the two telescopic plates are disposed within the four square grooves; equidistant fitting grooves are formed on the outer walls of one side of the two first base frames and the two second base frames; two movable blocks are respectively disposed on the outer walls of one side of the two telescopic plates; and the four movable blocks cooperate with the fitting grooves. An adjustment mechanism: the adjustment mechanism is disposed on the two first base frames. The open corner bracket for fixing the inner corner of a bed frame provided by this utility model has an innovative design structure, changes the fixing method, and reduces operational difficulty.

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0022] The open corner bracket disclosed in this utility model for fixing the inner corner of a bed frame is mainly used in the traditional open corner bracket for fixing the inner corner of a bed frame. When using it, the structure is relatively simple, the fixing method is relatively outdated, the operation steps are relatively cumbersome, and the requirements for the staff are very high. It is easy for the right angle fixing angle to be inaccurate, which may affect the use of the bed frame.
[0023] Reference Figure 1 and Figure 2 An open corner bracket for fixing the inner corner of a bed frame includes two first base frames 1 and a second base frame 2 disposed on one side of the two first base frames 1. It also includes: a fixing mechanism: the fixing mechanism includes telescopic plates 6 disposed between the two first base frames 1 and the two second base frames 2. Square grooves are formed on the outer walls of opposite sides of the two first base frames 1 and the two second base frames 2. The two telescopic plates 6 are disposed inside the four square grooves. Equally spaced adapter grooves 8 are formed on the outer walls of one side of the two first base frames 1 and the two second base frames 2. Two movable blocks 7 are respectively disposed on the outer walls of one side of the two telescopic plates 6. The four movable blocks 7 cooperate with the adapter grooves 8. An adjustment mechanism: the adjustment mechanism is disposed on the two first base frames 1.
[0024] Among them, the two first base frames 1 and the two second base frames 2 are all set to "L" shape.
[0025] Specifically, in this solution, four “L”-shaped first base frames 1 and second base frames 2 are combined to form two upward-opening “U”-shaped slot-shaped corner brackets. With the bottom retractable telescopic plate 6, the equally spaced adapter slots 8, and the two movable blocks 7, one of the first base frames 1 and the second base frame 2 can be placed on one side of the bed frame during use. Then, the other bed frame that needs to be fixed at a right angle is placed into the “U”-shaped slot formed by the first base frame 1 and the second base frame 2. The telescopic plate 6 is then adjusted to a suitable position to fix the bed frame securely. This fixing method not only reduces the difficulty of fixing the corners inside the bed frame, but also avoids the situation of inaccurate right-angle fixing angle caused by manual adjustment through the right-angle fixing design.
[0026] Two movable slots are respectively opened on one side of the outer wall of the two telescopic plates 6, and springs are installed inside the four movable slots. The four springs are connected to the four movable blocks 7.
[0027] Specifically, by using the movable groove and movable block 7 set on the telescopic plate 6, and with the spring inside the movable groove, when it is necessary to adjust the telescopic plate 6, the movable block 7 can be released from the adapter groove 8 by pressing the movable block 7, and then the hand can be released and fixed in the appropriate position.
[0028] Reference Figure 1 and Figure 3In a preferred embodiment, the adjustment mechanism includes elongated slots provided on the top outer walls of the two first base frames 1 and the two second base frames 2. Each of the four elongated slots is provided with a first fixed shaft 9 and a second fixed shaft 11. Two first connecting rods 3 are connected to the outer circumference of each of the four first fixed shafts 9, and two second connecting rods 4 are connected to the outer circumference of each of the four second fixed shafts 11.
[0029] Among them, the two first links 3 are used in conjunction with the two second links 4.
[0030] Specifically, by setting the first fixed shaft 9 and the second fixed shaft 11 between the two first base frames 1 and the two second base frames 2, and cooperating with the first connecting rod 3 and the second connecting rod 4, the two open corner brackets are connected into a whole. The spacing between them can be controlled by the first connecting rod 3 and the second connecting rod 4. When installing the bed frame, the contact area with the bed frame is increased. Multiple open corner brackets can be connected by only one connector, reducing the number of open corner brackets used and improving the fixing efficiency of the open corner brackets.
[0031] Reference Figure 1 and Figure 3 In a preferred embodiment, two connecting frames 5 are also connected between the two first connecting rods 3 and the two second connecting rods 4 via bearings.
[0032] Specifically, by using four connecting brackets 5 between the two first connecting rods 3 and the two second connecting rods 4, the two first connecting rods 3 and the two second connecting rods 4 can be simply fixed, while the bearing connection also avoids affecting the adjustment of the movement between the two first connecting rods 3 and the two second connecting rods 4.
[0033] Reference Figure 2 and Figure 4 In a preferred embodiment, two threaded holes are respectively opened on one side outer wall of the two first base frames 1 and the two second base frames 2, and fixing nails 10 are provided inside the eight threaded holes.
[0034] Working principle: When in use, first place the device on one side of the bed frame, then place the other bed frame that needs to be fixed at a right angle into the "U"-shaped groove formed by the first base frame 1 and the second base frame 2. Then, release the movable block 7 from the adapter groove 8 by pressing the movable block 7, and release it in the appropriate position to fix it. Adjust the telescopic plate 6 to the appropriate position to fix the bed frame firmly. Then, through the first fixing shaft 9 and the second fixing shaft 11 set between the two first base frames 1 and the two second base frames 2, in conjunction with the first connecting rod 3 and the second connecting rod 4, the distance between the two first base frames 1 and the two second base frames 2 is widened, and then fixed one by one with fixing nails 10.
[0035] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
