The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.

As shown in fig. 1, it is a schematic structural diagram of a thermal infrared imager with a rotatable detection head according to the present invention, and includes a detection head 10 and a hand piece 20. A rotation shaft 11 is provided between the detection head 10 and the hand piece 20. The first positioning member 21 and the second positioning member 22 are respectively provided at the left and right ends of the rotating shaft 11. The first end 111 of the rotary shaft 11 is rotatably engaged with the first positioning member 21, and the second end 112 of the rotary shaft 11 is rotatably engaged with the second positioning member 22, so that the detection head 10 can be rotated along the axis of the rotary shaft 11 with respect to the hand-held portion 20 and folded. The detection head 10 and the rotation shaft 11 may be fixedly connected to rotate together, or may be separated into two freely movable components, for example, when the rotation shaft 11 is fixed, the detection head 10 may rotate around the upper end surface of the rotation shaft 11 by 0 to 360 degrees. In different embodiments, the first positioning element 21 and the second positioning element 22 may be fixedly connected to the hand piece 20, or may be integrally formed as a same component. In other embodiments, the rotation shaft 11 may be integrally connected to a plastic member covering the rotation shaft 11, and the plastic member is connected to the detection head 10 and the hand piece 20 respectively to jointly implement the rotation function.
The rotation matching manner between the rotation shaft 11 and the first positioning element 21 and the second positioning element 22 may be that the rotation shaft 11 and the first positioning element 21 and the second positioning element 22 are sleeved with each other, or the rotation shaft 11 and the first positioning element 21 and the second positioning element 22 are communicated with each other through other rotation connecting elements, for example, the rotation connecting element may be a conventionally used component such as a screw, for example, when the screw is used, a thread is provided in the rotation shaft 11 corresponding to the rotation connecting element.
Since the cable connection is needed between the detection head 10 and the inside of the hand piece 20 for working, the existing method is that the cable passes through the inside of the detection head 10, passes through the inside of the rotating shaft 11, and passes through the inside of the hand piece 20 from the upper end of the hand piece 20. When the detection head 10 is rotated forward or backward by a certain angle with respect to the hand piece 20, the cable for connecting the detection head 10 with the inside of the hand piece 20 is stretched to some extent in the rotation shaft 11. Therefore, in order to avoid machine failure caused by repeated bending and stretching of the cable, the rotating shaft 11, the first positioning member 21 and the second positioning member 22 need to be improved to reduce stretching and abrasion of the cable when the cable passes through the rotating shaft 11, the first positioning member 21 and the second positioning member 22.
Fig. 2 is an enlarged schematic view of a part of the structure of the present invention. In one embodiment, the rotating shaft 11, the first positioning member 21 and the second positioning member 22 are hollow inside, and the insides communicate with each other. The shapes of the first positioning element 21 and the second positioning element 22 can be designed according to the overall shape of the thermal infrared imager. For example, the first positioning member 21 and the second positioning member 22 may be cylindrical. The side wall of the rotary shaft 11 is provided with a first threading port 113. The side wall of the first positioning member 21 is provided with a second threading opening 213. The first threading opening 113 communicates with the inner cavity of the detection head 10 and the inner cavity of the rotary shaft 11, and communicates with the second threading opening 213. The top of the hand piece 20 is also provided with an opening for a cable to pass through so that the cable can pass through the second threading opening 213 and the opening to pass into the lumen of the hand piece 20. Because the cable rotates along with the rotating shaft 11 at the first threading opening 113, the cable at the second threading opening 213 cannot move along with the rotation of the detection head 10, and the stretching of the cable is avoided. Preferably, the second threading opening 213 is disposed on the bottom wall of the first positioning element 21, so that the inner cavity of the first positioning element 21 is communicated with the inner cavity of the hand piece 20, the path through which the cable is connected with the inner cavity of the hand piece 20 is reduced, and the number of times of bending the cable is further reduced. In this embodiment, the second threading opening 213 is located on the sidewall of the first positioning element 21, but the embodiment is not limited thereto, and the first positioning element 21 and the second positioning element 22 can be configured in the same way.
In a preferred embodiment, as shown in fig. 2, a first end 111 of the rotating shaft 11 is rotatably connected to the first positioning member 21 through a first rotating connector 31, and a second end 112 of the rotating shaft 11 is rotatably connected to the second positioning member 22 through a second rotating connector 32. Specifically, the first rotating connector 31 and the second rotating connector 32 may be screws, respectively, and the rotating shaft 11 is provided with threads at positions corresponding to the first rotating connector 31 and the second rotating connector 32, and the screws are engaged with the threads to fix the rotating shaft 11.
The side wall of the rotating shaft 11 is also provided with a first fixing hole 114 and a second fixing hole 115. The first fixing hole 114 is used for accommodating a first fixing member, and the first fixing member enables the first rotating connecting member 31 to be fixedly sleeved on the first end 111 of the rotating shaft 11. The second fixing hole 115 is used for receiving a second fixing member, which enables the second rotating connecting member 32 to be fixedly sleeved on the first end 112 of the rotating shaft 11.
In other embodiments, the first threading opening 113 is disposed in an elliptical shape along the axial direction of the rotating shaft 11, so that the cable has a large moving space at the first threading opening 113, and the cable is not bent excessively at the first threading opening 113.
When the thermal infrared imager with the rotatable detection head provided by the embodiment of the utility model is installed, a cable firstly passes through the bottom of the cavity of the detection head 10, then passes through the first threading opening 113, enters the cavity of the rotating shaft 11, passes through the second threading opening 213, and then enters the hand piece 20. Since the first threading opening 113 rotates with the detection head 10 and the second threading opening 213 is fixed, when the detection head 10 rotates back and forth along the rotation axis 11, the cable at the first threading opening 113 can rotate with the detection head 10 at the first threading opening 113 without being stretched or stretched, and the cable at the second threading opening 213 can be kept stable and immovable.
According to the thermal infrared imager with the rotatable detection head, the first threading opening 113 is formed in the rotating shaft 11, the second threading opening 213 is formed in the first positioning piece 21 or the second positioning piece 22, so that cables penetrating through the first threading opening 113 and the second threading opening 213 can not be stretched excessively when the detection head 10 rotates to adjust the angle, the cables only need to rotate along with the rotation of the detection head 10 at the first threading opening 113, and the cables are not damaged.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
