Abstract
The utility model discloses a split type pendulous reed which comprises a pendulous reed body and a pendulous reed handle, wherein the pendulous reed handle comprises a fixed part and a movable part, one end of the fixed part of the pendulous reed handle is fixedly connected with the pendulous reed body, and the other end of the fixed part of the pendulous reed handle is provided with a semicircular groove; and one end of the movable part of the pendulous reed handle is also provided with a semicircular groove, the fixed part of the pendulous reed handle is movably connected with the end part of the movable part of the pendulous reed handle, which is provided with the semicircular groove, through a screw, and the two connected semicircular grooves form a circular shaft hole.
Description
Technical field
The utility model relates to the structure of used pendulum in a kind of infrared imaging mechanism.
Background technology
In infrared imaging mechanism, use a kind of pendulum, drive its rotary work through direct current machine.Like Fig. 1, shown in Figure 2, said pendulum comprises pendulum body 1 and pendulum handle 2 ', and pendulum handle 2 ' is provided with axis hole 3, and the output shaft 5 of direct current machine 4 is fixed in the axis hole 3, relies on direct current machine 4 to rotate and drives the pendulum rotation.This mode is applicable to the situation of motor output shaft more than or equal to φ 3mm; Because when motor output shaft during, can on axle, establish a facet 6, utilize this facet 6 as installing and fixing face more than or equal to φ 3mm; Screw through dog screw 7 and axis hole side; Can pendulum handle and motor output shaft be fixed, but, just be difficult to such plane has been set when motor output shaft during less than φ 3mm.Can't motor shaft and pendulum handle be fixed through set screw in such cases, can only pendulum handle and motor shaft be sticked together with glue, this practice was both unreliable, was not easy to dismounting again and changed pendulum.
Summary of the invention
The purpose of the utility model is to provide the structure of used pendulum in the infrared imaging mechanism, solves fixing and trim pendulum on the small axle diameter motor.
The technical scheme of the utility model is following:
A kind of split type pendulum comprises pendulum body and pendulum handle, it is characterized in that: said pendulum handle comprises standing part and movable part, and an end of said pendulum handle standing part is fixedly connected with the pendulum body, and the other end is provided with a semi-circular recesses; One end of said pendulum handle movable part also is provided with a semi-circular recesses, and the end that said pendulum handle standing part and movable part are provided with semi-circular recesses flexibly connects through screw, and two semi-circular recesses after the connection are formed a circular axis hole.
The utility model is set to the branch body structure through the pendulum handle, and the diameter of the semi-circular recesses that is provided with on each part equals the diameter of motor shaft, after two parts are connected, can motor shaft tightly be fixed like this.This structure no matter diameter of motor shaft all is suitable for, and has solved when motor shaft is too small, to be difficult at present and problem that the pendulum handle is fixed.The utility model also can be adjusted the weight of pendulum handle movable part, makes the barycenter of pendulum be positioned at the motor shaft place.

Embodiment
Like Fig. 3, shown in Figure 4, the utility model comprises pendulum body 1 and pendulum handle 2, and said pendulum handle 2 comprises standing part 21 and movable part 22, and an end of said pendulum handle standing part 21 is fixedly connected with pendulum body 1, and the other end is provided with a semi-circular recesses 211; One end of said pendulum handle movable part 22 also is provided with a semi-circular recesses 221; Said pendulum handle standing part 21 flexibly connects through screw 8 with the end that movable part 22 is provided with semi-circular recesses, and two semi-circular recesses 211 after the connection and 221 are formed a circular axis hole.
In the practical implementation process, can be according to the diameter of motor output shaft, make the diameter of doing circular groove on pendulum handle standing part and the movable part end equal the diameter of motor output shaft.
The output shaft 5 of motor 4 is placed between the semi-circular recesses of pendulum handle standing part and movable part, pendulum handle standing part 21 is connected with movable part 22, just can motor output shaft 5 tightly be fixed through screw 8.
In the utility model practical implementation process; Also can select the material of different densities to pendulum handle movable part and pendulum body and pendulum handle standing part for use, pendulum handle movable part is selected the bigger material of density for use, and pendulum body and pendulum handle standing part are selected the density materials with smaller for use; Like this; Through calculating both volumes of adjustment, just can be so that the barycenter of whole pendulum is positioned at the motor shaft place, thus make pendulum to be parked in any position around motor output shaft.
