Description

Technical Field

[0001] The utility model relates to the technical field of building installation structures, in particular to an adjustable bridge. Background Technique

[0002] In the traditional solution, during on-site construction, the bending of the bridge is usually processed, cut and fabricated by on-site construction workers according to on-site measurements. However, the self-fabricated bent bridge has the following problems:

[0003] ① If the fabricated bent bridge does not match, it needs to be remade, which affects the construction efficiency; moreover, the self-fabricated bridge

[0004] ② The self-fabricated bridge affects the aesthetics and is prone to rust;

[0005] ③ If the burrs of the self-fabricated bridge are not polished properly, they will cut the outer skin of the cable, affecting the use function.

[0006] In addition, there is also an adjustable-angle bridge in the traditional solution, but after it is bent at a certain angle, its structure is not stable enough, and the angle at the bending part is not stable enough. It is prone to slip and deformation under stress, resulting in inability to meet on-site requirements. Content of the Utility Model

[0007] The purpose of the utility model is to solve at least one technical problem in the background technique, and provide an adjustable bridge.

[0008] To achieve the above purpose, the utility model provides an adjustable bridge, including:

[0009] The first bridge;

[0010] The second bridge, with a width smaller than that of the first bridge, one end of which is rotatably connected to one end of the first bridge, and the angle formed between the first bridge and the second bridge is adjusted through the rotatable connection;

[0011] The first fixing structure is arranged at the side wall connection of the first bridge and the second bridge, and is used to lock the first bridge and the second bridge;

[0012] The second fixing structure is arranged adjacent to the first fixing structure, and is used to lock the first bridge and the second bridge and fix the angle between the first bridge and the second bridge.

[0013] According to one aspect of the utility model, the first bridge is provided with a first inner flange and a first open part, the first inner flange and the first open part are arranged adjacent to each other, and the first open part is arranged close to the second bridge.

[0014] According to one aspect of the utility model, a second inner flange and a second opening portion are provided on the second bridge frame, the second inner flange and the second opening portion are arranged adjacent to each other, and the second opening portion is arranged close to the first bridge frame.

[0015] According to one aspect of the utility model, the first fixing structure comprises: an arc-shaped slot and a positioning bolt;

[0016] The arc-shaped groove is arranged through the side walls of the first bridge frame and the second bridge frame;

[0018] According to one aspect of the utility model, the second fixing structure includes: a rotation fixing protrusion and a rotation fixing rod;

[0019] The rotation fixing protrusion is arranged on the side wall of the first bridge frame or the second bridge frame;

[0021] According to one scheme of the utility model, the adjustable bridge includes: a first bridge; a second bridge having a width smaller than that of the first bridge and one end of which is rotatably connected to one end of the first bridge, and the angle formed between the first bridge and the second bridge is adjusted by the rotatable connection; a first fixing structure, which is arranged at the connection between the side walls of the first bridge and the second bridge and is used to lock the first bridge and the second bridge; and a second fixing structure, which is arranged adjacent to the first fixing structure and is used to lock the first bridge and the second bridge and fix the angle between the first bridge and the second bridge. Such a setting can make it possible to arbitrarily adjust the angle between the first bridge and the second bridge, and form any angle according to on-site needs. After the angle is adjusted, the first bridge and the second bridge can be preliminarily locked by the first fixed structure, and a pre-tightening force is provided during the adjustment of the first bridge and the second bridge, ensuring that the process of adjusting the angle is more convenient and quick, and the adjustment does not require the cooperation of multiple people, and there will be no problem of not being able to quickly adjust to the required angle and position due to the structure being too loose. After the first bridge and the second bridge are preliminarily locked by the first fixed structure, the position between the first bridge and the second bridge can be locked by the second fixed structure, ensuring that the position between the first bridge and the second bridge no longer changes, ensuring that the corresponding angle can be maintained under the action of external force, and ensuring the stability and reliability between the first bridge and the second bridge.

It should be emphasized that in the present utility model, the lengths of the first open part and the second open part can be set according to the on-site requirements to achieve different adjustable angle ranges through the cooperation of the first open part and the second open part.

With such an arrangement, the angle between the first bridge frame and the second bridge frame can be adjusted by flipping the first bridge frame or the second bridge frame. During the process of adjusting to the target angle, the positioning bolt can be slid to the overlapping part of the side walls of the first bridge frame and the second bridge frame, and then the positioning bolt is pre-tightened (i.e., in a non-fully locked state). Then, fine adjustment can be performed on the first bridge frame or the second bridge frame in the pre-tightened state to make the angle between the first bridge frame and the second bridge frame accurate. After fine adjustment, the positioning bolt is fully locked to ensure that the angle between the first bridge frame and the second bridge frame remains fixed in a non-loaded state or a state with less force.

As Figure 1 and Figure 2 shown, in this embodiment, the adjustable bridge includes:

[0031] The first bridge 1;

[0032] The second bridge 2, with a width smaller than that of the first bridge 1, one end of which is rotatably connected to one end of the first bridge 1, and the angle formed between the first bridge 1 and the second bridge 2 is adjusted through the rotational connection;

[0033] The first fixing structure 3, which is arranged at the side wall connection of the first bridge 1 and the second bridge 2 and is used to lock the first bridge 1 and the second bridge 2;

[0034] The second fixed structure 4 is arranged adjacent to the first fixed structure 3, and is used to lock the first bridge 1 and the second bridge 2 and fix the angle between the first bridge 1 and the second bridge 2. Such arrangement enables the angle between the first bridge 1 and the second bridge 2 to be adjusted arbitrarily, and any angle can be formed according to the needs of the site, and after the angle is adjusted, the first bridge 1 and the second bridge 2 can be preliminarily locked by the first fixed structure 3, and a pre-tightening force is provided during the adjustment of the first bridge 1 and the second bridge 2, so as to ensure that the angle adjustment process is more convenient and quick, and the adjustment does not require the cooperation of multiple people, and there will be no problem of being unable to quickly adjust to the required angle and position due to the structure being too loose; after the first bridge 1 and the second bridge 2 are preliminarily locked by the first fixed structure 3, the position between the first bridge 1 and the second bridge 2 can be locked by the second fixed structure 4, so as to ensure that the position between the first bridge 1 and the second bridge 2 does not change, and to ensure that the corresponding angle can be maintained under the action of external force, and to ensure the stability and reliability between the first bridge 1 and the second bridge 2.

[0035] Furthermore, if Figure 1 and Figure 2 As shown, in this embodiment, a first inner flange 5 and a first opening portion 6 are provided on the first bridge 1 , the first inner flange 5 and the first opening portion 6 are arranged adjacent to each other, and the first opening portion 6 is arranged close to the second bridge 2 .
