Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example.

1-2, a near-infrared online measuring instrument based on reflection measurement includes a base 1, and a measuring instrument 9 is arranged on the base 1.

The base 1 is provided with a rotating mechanism. The rotating mechanism includes a rotating rod 10 that is rotatably connected to the upper side wall of the base 1. The side wall of the rotating rod 10 is fixedly connected with a pointer 16, and the upper end of the rotating rod 10 is fixedly connected to the lower side wall of the measuring instrument 9. The side wall of the rod 10 is fixedly connected with a spur gear 11, the upper side wall of the base 1 is fixedly connected with a fixed frame 15, the upper side wall of the fixed frame 15 is provided with a scale line, the pointer 16 is aligned with the scale line, and the upper side wall of the fixed frame 15 is provided with a tick mark. The placement port 17, the rotating rod 10 is located in the placement port 17, the side wall of the fixed frame 15 is provided with a round rod 13, the left end of the round rod 13 is fixedly connected with a crown gear 12, the spur gear 11 meshes with the crown gear 12, the diameter of the spur gear 11 Much larger than the diameter of the crown gear 12 , a handle 14 is fixedly connected to the right end of the round rod 13 , and the side wall of the handle 14 is provided with a non-slip sleeve to prevent people from disengaging when turning the handle 14 .

The base 1 is provided with a protection mechanism, the protection mechanism includes a support plate 2 fixedly connected to the upper side wall of the base 1, the side wall of the support plate 2 is provided with an opening 3, and a protection cover 4 is arranged in the opening 3, and the diameter of the protection cover 4 is larger than The diameter of the measuring instrument 9 ensures that the measuring instrument 9 can be located in the protective cover 4. Two rectangular blocks 5 are fixedly connected to the side walls of the protective cover 4. The lower side walls of the two rectangular blocks 5 are in contact with the upper side walls of the support plate 2 to prevent The protective cover 4 slides down from the opening 3, the side wall of the protective cover 4 is provided with a limit groove 8, the inner wall of the opening 3 is provided with a cross bar 6, and the right end of the cross bar 6 is fixedly connected with a handle 7, and the handle 7 is connected to the support plate 2 through a spring. The side walls are elastically connected, and the springs are sleeved on the side walls of the cross bar 6 .

The functional principle of the utility model can be explained by the following operation methods: when in use, the protective cover 4 is pulled upward, and when the limit groove 8 is matched with the cross bar 6, the handle 7 drives the cross bar 6 to move to the position under the elastic force of the spring. In the limiting groove 8 , the fixing of the protective cover 4 is realized.

Rotate the handle 14, thereby driving the round rod 13 to rotate, thereby driving the crown gear 12 to rotate, thereby driving the spur gear 11 to rotate, thereby driving the rotating rod 10 to rotate, thereby driving the measuring instrument 9 to rotate, avoiding that the measuring instrument 9 can only be carried out in one direction. For distance measurement, when the rotating rod 10 rotates, it will also drive the pointer 16 to rotate. Since the diameters of the spur gear 11 and the crown gear 12 are quite different, the crown gear 12 rotates several times to drive the spur gear 11 to rotate once, so that the rotating rod 10 rotates faster Therefore, the rotating speed of the measuring instrument 9 is slow, and with the scale line on the fixing frame 15 , people can adjust the rotation angle of the measuring instrument 9 more accurately.
