Anti-falling type automatic instrument

Abstract

The invention discloses an anti-falling type automatic instrument which comprises an instrument body. A protective cover is arranged on the outer side of the instrument body, a limiting plate is fixedly arranged at the bottom of the instrument body, a nut groove is formed in the middle of the bottom end of the instrument body, two first locking nuts are arranged in the middle of the bottom end ofthe limiting plate, a first connecting plate is arranged at the bottoms of the first locking nuts, a first screw hole is formed in the middle of the top end of the limiting plate, a fastening bolt isin threaded connection with the interior of the first screw hole, and a nut of the fastening bolt is arranged in the nut groove. Through the arrangement of a first damping spring, a second damping spring and a third damping spring, when the automatic instrument accidentally falls to the ground, the external impact force can be reduced through the elastic action of the first damping spring, the second damping spring and the third damping spring before the external impact force is conducted to the automatic instrument body, therefore, the damping and anti-falling effects are achieved, and the internal structure of the automatic instrument is effectively protected.

Description

technical field [0001] The invention relates to an instrument, in particular to an anti-fall automatic instrument. Background technique [0002] Automated instruments are composed of several automation components and are automation technology tools with relatively complete functions. They are widely used in the field of electrical engineering and automated production. They can detect and read various parameters in the automation system, and finally pass through the instrument panel. display. [0003] In view of this, an automatic instrument sealing device proposed by Chinese Patent No. CN210219243U can drive the cover to be fixed by clamping the post in the slot, and then turn the second bolt backward to fix the cover on the front of the bearing frame. side, which improves the sealing of the device; Chinese Patent No. CN209912506U proposes a fall-proof automatic instrument, by using four first fixing screws to make the protective pad be fixed on the front side of the shell,...

[0003] In view of this, an automatic instrument sealing device proposed by Chinese Patent No. CN210219243U can drive the cover to be fixed by clamping the post in the slot, and then turn the second bolt backward to fix the cover on the front of the bearing frame. side, which improves the sealing of the device; Chinese Patent No. CN209912506U proposes a fall-proof automatic instrument, by using four first fixing screws to make the protective pad be fixed on the front side of the shell, so that when the shell falls to the ground , through the protection of the protective pad, the glass on the front side of the shell is not easily damaged; Chinese patent number CN208091476U proposes a meter testing device with a simple structure, low manufacturing cost, easy operation, and can quickly stabilize the meter. It is also suitable for different specifications Instruments can improve work efficiency; and the instruments in the above patents are not equipped with shock-absorbing structures, so when the instrument falls accidentally, it cannot reduce the external impact force well, and then at the same time, the interior of the instrument The structure and the external structure are protected, resulting in weak practicability
