Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
A kind of portable pendulum tester of controllable oscillating bar length of the utility model, as shown in Figure 1, include the support rod 7 of adjustment height,
Support rod 7 can adjust height by locking nut, and the lower end of support rod 7 is provided with pedestal 10, and the upper lateral part of support rod 7 is vertically set
It is equipped with shaft, crossbeam 14 is fixed in shaft, the upper end of crossbeam 14 is provided with handle 9, and it is easy to carry, table is connected on crossbeam 14
Disk 11, also rotation is provided with fixed link 1 and indicating arm 12 in shaft, and 1 middle and lower part of fixed link is hollow and open-ended, fixed link 1
Sliding bar 2 is arranged in middle and lower part, fixed link 1 is stretched out in 2 one end of sliding bar, and 2 extension end of sliding bar is provided with yaw 13, yaw
13 lower ends are equipped with friction rubber piece, and fixed link 1 is connect with sliding bar 2 by multiple fixed screws 3, as shown in Fig. 2, passing through rotation
Fixed screw 3 can realize the fixation and sliding of sliding bar 2；
Corresponding position is provided with fixation hole 4 matched with fixed screw 3 in fixed link 1 and sliding bar 2；
As shown in figure 3,1 middle and lower part side wall of fixed link is in be vertically disposed with two location holes 5, the center of two location holes 5
At a distance of 3.92mm, position-sensing switch is provided in one of location hole 5, position-sensing switch includes open at one end and horizontally disposed set
Cylinder 16, the outer diameter of 16 inner hollow of sleeve, sleeve 16 is equal with the internal diameter of location hole 5, the setting of 16 closed end outer horizontal of sleeve
