Detailed Description
The invention is described in detail below with reference to the drawings and the specific embodiments.
Example 1
A microscope, a stage 1 is provided on top of a base 2 via a lifting column.
The limiting device consists of an L-shaped trigger 3 and an alarm circuit. The alarm circuit consists of an end part of an L-shaped trigger 3, a limiting block, a power supply 8 and an audible and visual alarm 7 which are sequentially connected in series through a lead 6.
As shown in fig. 1, the limiting blocks are 2, namely a first limiting block 4 and a second limiting block 5, and are fixedly arranged on the side surface of the base 2 along the height direction. The L-shaped trigger 3 is suspended at the bottom of the objective table 1, and the end part of the L-shaped trigger 3 is arranged between the first limiting block 4 and the second limiting block 5.
The audible and visual alarm 7 comprises a warning lamp and a buzzer and is also arranged on the side surface of the base 2.
In the use process, the water-soluble fiber is prepared,
When the lifting column moves upwards, the objective table 1 is linked with the L-shaped trigger 3 upwards, the end part of the L-shaped trigger 3 contacts the first limiting block 4, the alarm circuit is conducted, the audible and visual alarm 7 is electrified, and audible and visual alarm is sent out.
When the lifting column moves downwards, the objective table 1 is linked with the L-shaped trigger 3 downwards, so that the end part of the L-shaped trigger 3 contacts the second limiting block 5, the alarm circuit is conducted, the audible and visual alarm 7 is electrified, and audible and visual alarm is sent out.
Example 2
Based on the structure of embodiment 1, the stopper is movably disposed on the side surface of the base 2 through the reset device.
The resetting device consists of a groove on the side surface of the base 2, a spring 9 and a guide rod 10.
The top surface and the bottom surface of the groove are respectively provided with a guide hole. The top surface and the bottom surface of the limiting block are respectively provided with a guide rod 10 matched with the guide Kong Pi. The guide rod 10 is placed in the guide hole so that the stopper can move up and down in the groove in the direction of the guide hole.
For the first limiting block 4, the spring 9 is sleeved on the guide rod 10 at the upper part, so that the top end of the spring 9 abuts against the top surface of the groove, and the bottom end of the spring 9 abuts against the limiting block.
For the second limiting block 5, the spring 9 is sleeved on the guide rod 10 at the lower part, so that the top end of the spring 9 abuts against the limiting block, and the bottom end of the spring 9 abuts against the top surface of the groove.
