[0001] The utility model relates to the technical field of L-shaped back ribs, in particular to an L-shaped back rib with adjustable angles. Background Art

[0002] Back rib refers to a cross-sectional shape in a profile that is used to enhance its lateral bending stiffness. It is a steel back rib, a cross-sectional curved piece in the shape of L or W. The steel back rib is used to withstand upper and lower pressures, and also has certain shear and torsional resistance.

[0003] The existing L-shaped back ribs are usually used as a single integral structure to ensure the overall stability of the back ribs. The angle of the back ribs cannot be adjusted during use, which limits the overall practicality. Therefore, we propose an L-shaped back rib with adjustable angle. Utility Model Content

[0012] In a further technical solution, the second bolt passes through the interior of the first mounting block and the second mounting block and extends to the outside.

[0013] The beneficial effects of the utility model are:

DETAILED DESCRIPTION

[0023] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0024] Example:

[0025] like Figure 1-Figure 5 As shown, the adjustable angle L-shaped back rib includes a first connecting rod 1 and a second connecting rod 2. The ends of the first connecting rod 1 and the second connecting rod 2 that are close to each other are connected with an angle adjustment mechanism 3. One end of the first connecting rod 1 and the second connecting rod 2 is provided with a through hole 4. The first connecting rod 1 and the second connecting rod 2 are movably connected to the angle adjustment mechanism 3 with a first bolt 5. The outer sides of the first connecting rod 1 and the second connecting rod 2 are connected with an angle fixing block 6 through the first bolt 5.

[0026] The working principle of the above technical solution is as follows:

[0027] During use, the first bolt 5 is rotated and disassembled, so that the angle fixing block 6 can be disassembled, and then the first connecting rod 1 and the second connecting rod 2 are opened to drive the angle adjustment mechanism 3 to deflect, and then the angle fixing block 6 is replaced so that the angle fixing block 6 can adapt to the angle between the first connecting rod 1 and the second connecting rod 2, and then the angle fixing block 6 is connected and fixed to the first connecting rod 1 and the second connecting rod 2 through the first bolt 5, so that the angle between the first connecting rod 1 and the second connecting rod 2 can be installed and fixed, which is easy to operate.

[0028] In another embodiment, if Figure 3 As shown, the angle adjustment mechanism 3 includes a first mounting block 7 and a second mounting block 9, one end of the first mounting block 7 is fixedly connected to the first connecting block 8, one end of the second mounting block 9 is fixedly connected to the second connecting block 10, the surfaces of the first connecting block 8 and the second connecting block 10 are both provided with mounting grooves 11, the inner side of the mounting groove 11 is provided with a first nut 12, and the first mounting block 7 and the second mounting block 9 are internally movably connected with a connecting assembly mechanism 13.

[0029] The connecting assembly mechanism 13 is convenient for connecting and assembling multiple groups of angle adjustment mechanisms 3 as a whole. At the same time, the first connecting rod 1 and the second connecting rod 2 can be respectively sleeved on the outer surface of the first connecting block 8 and the second connecting block 10, and the first bolt 5 is inserted into the inner side of the through hole 4 to connect with the first nut 12, so as to quickly assemble.

[0030] In another embodiment, if Figure 1 and Figure 3 As shown, the through hole 4 and the first nut 12 are aligned with each other, and the inner side of the mounting groove 11 and the outer side of the surface of the first nut 12 fit each other.

[0031] When the first connecting rod 1 and the second connecting rod 2 are respectively sleeved on the outer sides of the surfaces of the first connecting block 8 and the second connecting block 10, the through holes 4 on the surfaces of the first connecting rod 1 and the second connecting rod 2 can be aligned with the first nut 12, thereby facilitating the installation and fixation of the first bolt 5.

[0032] In another embodiment, if Figure 1 and Figure 3 As shown, the first mounting block 7 and the second mounting block 9 fit together, and the first connecting block 8 and the second connecting block 10 fit together with the inside of the first connecting rod 1 and the second connecting rod 2 respectively.

[0033] The devices can be quickly assembled and used with each other, and have a simple structure and are easy to use.

[0034] In another embodiment, if Figure 5 As shown, the connection assembly mechanism 13 includes a second bolt 14 , a separation sleeve rod 16 is movably sleeved on the outer surface of the second bolt 14 , and a second nut 15 is movably sleeved on the outer surface of the other end of the second bolt 14 .

[0035] It is convenient to insert the second bolt 14 into the first mounting block 7 and the second mounting block 9 for connection and fixation, and then lock it by installing and fixing the second nut 15. The separation sleeve rod 16 can separate the multiple groups of angle adjustment mechanisms 3 as a whole, and the operation is convenient and quick.

[0036] In another embodiment, if Figure 3 and Figure 5 As shown, the two ends of the separation sleeve rod 16 are respectively in contact with the outer sides of the adjacent first mounting blocks 7 .

[0037] The separation sleeve rods 16 can be separated, so that multiple groups of angle adjustment mechanisms 3 can be quickly installed and used as a whole, which is easy to operate.

[0038] In another embodiment, if Figure 3 As shown, the second bolt 14 passes through the interior of the first mounting block 7 and the second mounting block 9 and extends to the outside.

[0039] This facilitates the second bolt 14 to be inserted into the first mounting block 7 and the second mounting block 9 , so that the first mounting block 7 and the second mounting block 9 can be deflected outside the surface of the second bolt 14 , thereby performing angle adjustment.

[0040] The working principle of the utility model is as follows: during use, the first bolt 5 is rotated and disassembled, and then the first connecting rod 1 and the second connecting rod 2 respectively drive the first connecting block 8 and the second connecting block 10 to deflect, thereby respectively driving the first mounting block 7 and the second mounting block 9 to deflect, so that the first mounting block 7 and the second mounting block 9 can be deflected at the same time on the outside of the surface of the second bolt 14, so as to adjust the angle between the first connecting rod 1 and the second connecting rod 2. After the angle adjustment between the first connecting rod 1 and the second connecting rod 2 is completed, the angle fixing block 6 suitable for the angle between the first connecting rod 1 and the second connecting rod 2 is replaced, so that the angle fixing block 6 can fit between the first connecting rod 1 and the second connecting rod 2, and finally the first bolt 5 is rotated and installed to connect the first bolt 5 with the first nut 12, and the angle fixing block 6 is installed and fixed, so that the angle between the first connecting rod 1 and the second connecting rod 2 can be installed and fixed, and the operation is convenient and quick.

[0041] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
