DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example 1

[0022] See also Figure 1 and Figure 2 An angle adjustable sensor includes a housing 1, a rubber hose 2 connected to one end of the housing and having resilience, a probe 3 connected to one end of the rubber hose, and a PCB board 4 arranged in the housing. First channels 5 are arranged on both sides of the rubber hose 2, and a second channel 6 is arranged on the rubber hose 2 below the two first channels. Figure 2 , Figure 5 As shown, a transverse partition 9 and a vertical partition 10 are fixed in the shell 1, and the upper cavity and the lower cavity of the shell are divided by the transverse partition 9, and the upper cavity is divided into a left cavity and a right cavity by the vertical partition 10. The PCB board 4 is located in the lower cavity, and the wire 7 on the probe 3 passes through the second channel 6 and extends into the lower cavity, and the extended end is electrically connected to the PCB board 4.

[0023] like Figure 2 As shown, pulling mechanisms are provided in the left cavity and the right cavity, and the two first channels 5 are respectively connected to the left cavity and the right cavity. Pull ropes 8 are respectively provided in the two first channels 5, and one end of the two pull ropes 8 is connected to the end of the rubber hose 2 close to the probe, and the other ends are respectively connected to the two pulling mechanisms. By pulling the pull ropes 8 through the pulling mechanisms, the rubber hose 2 can be bent toward the pulling side.

[0024] Specifically, Figure 3 , Figure 4 , Figure 5 As shown, the pulling mechanism includes a rotating shaft 11 rotatably connected to the transverse partition and the top of the shell, a retracting wheel 12 connected to the rotating shaft, and a knob 13 connected to the outer end of the rotating shaft. The pull rope 8 is wound around the retracting wheel 12. A plurality of first positioning holes 14 are provided at the top of the shell 1 below the knob 13, and a second positioning hole is provided on the knob 13. When the knob is rotated, the positioning rod is inserted into the second positioning hole and the first positioning hole, so that the knob can be fixed on the shell.

[0025] like Figure 3 As shown, the connection between the housing 1 and the first channel 5 is rotatably connected with a guide wheel 16, and the pull rope 8 is passed around the guide wheel 16 and then wound around the retracting wheel 12. The pull rope is guided by the guide wheel 16 to prevent the pull rope from breaking. Here, the pull rope can be made of a line similar to a fishing line, such as a PE line, etc., to increase the strength and prevent it from breaking.

[0026] The working principle of this embodiment is as follows: Figure 6As shown in the figure, after the probe enters the pipeline, turn the knob on either side to drive the corresponding retracting wheel to rotate, thereby reeling in the drawstring, which pulls the rubber hose close to the probe end to bend the rubber hose, thereby adjusting the angle of the probe, which is very convenient. Since the rubber hose has resilience, when the drawstring is released, the rubber hose will return to its original state under the action of the resilience, that is, remain in the vertical state. In addition, the drawstring has a small diameter and occupies a small space, thereby reducing the volume of the rubber hose, making it easier for the probe and the rubber hose to extend into pipelines with smaller inner diameters, and having a wide range of uses.

[0027] Example 2

[0028] The difference between this embodiment and the first embodiment is that a mounting plate 17 is connected to the bottom of the housing 1, and mounting holes are provided at the four corners of the mounting plate. The utility model can be fixed at a desired position through the mounting plate and the mounting holes to operate the pulling mechanism.
