The structure of the utility model is simple and environmentally friendly, and the disassembly and assembly difficulty is low, with strong practicability.

[0003] However, when this device is in use, the angle of the device is fixed and cannot be adjusted, so the applicability of the device is poor. At the same time, when the device is connected to the bridge, the installation error makes the connection and installation of the device not convenient enough. Summary of the Invention

[0004] The purpose of the utility model is to provide an adjustable bridge elbow, which solves the problems that the angle of the existing bridge elbow device is fixed and cannot be adjusted, and the applicability of the device is poor, and when the device is connected to the bridge, the installation error makes the connection and installation of the device not convenient enough.

[0005] In order to achieve the above purpose, the utility model provides an adjustable bridge elbow, which includes two fixed frames. The two fixed frames are rotatably connected. A support shaft is rotatably connected inside the fixed frame. An adjusting mechanism is arranged on the fixed frame. A sliding frame is slidably connected inside the fixed frame. A support plate is fixedly connected inside the fixed frame. A screw rod is installed inside the support plate through a bearing. A connecting plate is fixedly connected inside the sliding frame. The connecting plate and the screw rod are connected by threads.

[0006] The principle of the present utility model lies in that when adjusting the device, manually rotate the screw ring and the bidirectional screw to perform a threaded movement, so that the screw ring and the screw sleeve are disengaged. Then manually rotate the bidirectional screw, and the bidirectional screw rotates and the screw sleeve performs a threaded movement, so that the screw sleeve drives the connecting rod to deflect, and then the angle between the two fixed frames changes. When the device is in use, the angle between the two fixed frames can be adjusted, so that the device has a wider application range and better applicability. When installing and using the device, manually rotate the screw and the connecting plate to perform a threaded movement, so that the sliding frame can slide within the fixed frame, and then the sliding frame can expand and contract relative to the fixed frame. When the device is connecting to the bridge, the connection and installation error can be reduced, making the device more convenient to use.

[0009] Furthermore, a guide bar is fixedly connected to the outer side of the sliding frame, and the guide bar is slidably connected to the fixed frame. By providing the guide bar, the movement of the sliding frame is guided.

[0010] Furthermore, a guide groove is formed inside the sliding frame, and the guide groove is slidably connected to the support plate. By providing the guide groove, the interference of the support plate on the movement of the sliding frame is avoided.

[0011] Furthermore, the adjusting mechanism includes a connecting rod. The surface of the fixed frame is hinged with the connecting rod, the end of the connecting rod is hinged with a screw sleeve, the inside of the screw sleeve is threadedly connected with a bidirectional screw, and the outer side of the support shaft is rotatably connected with a support rod. By rotating the bidirectional screw and the screw sleeve to perform a threaded movement, the screw sleeve drives the connecting rod to deflect.

[0012] Furthermore, a screw ring is threadedly connected to the outer side of the bidirectional screw, and the screw ring contacts the screw sleeve. By providing the screw ring, the relative rotation between the bidirectional screw and the screw sleeve is avoided.

[0013] Furthermore, a knob is fixedly connected to the outer side of the bidirectional screw, and the support rod is rotatably connected to the knob. By providing the support rod, the knob is limited.

[0014] Further, a retaining ring is fixedly connected to the outer side of the support shaft, and the retaining ring contacts the support rod. By providing the retaining ring, the support rod is limited. BRIEF DESCRIPTION OF THE DRAWINGS
