Problems solved by technology

[0004] Because the ammeter is a precision measuring instrument with many parts inside, it is easy to be damaged after being hit. In the prior art, most of the ammeters can only rely on the shell to prevent the impact. Even if it will not break, the larger vibration will not Will interfere with the normal use of the ammeter

Embodiment 1

[0042] see Figure 1-3 , a self-warning anti-collision ammeter, comprising an ammeter body 1, the outer end of the ammeter body 1 is covered with a magnetic shielding layer 2, and the outer end of the magnetic shielding layer 2 is fixedly connected with a plurality of evenly distributed anti-collision strips 3, and the anti-collision The bar 3 is arranged vertically, the end of the magnetic shielding layer 2 close to the anti-collision bar 3 is fixedly connected with a plurality of evenly distributed energy-absorbing bags 5, and the end of the anti-collision bar 3 close to the energy-absorbing bag 5 is fixedly connected with a plurality of evenly distributed force-collecting columns 4. The force-collecting column 4 corresponds to the energy-absorbing bag 5. The force-collecting column 4 includes an extended chassis 41, a shrinking column body 42, and a static magnetic ring 43. The extended chassis 41 is fixedly connected to the anti-collision strip 3, and the static magnetic ri...

Abstract

The invention discloses a self-warning anti-collision ammeter, which belongs to the technical field of electric meters. The invention can play the role of anti-collision by adding anti-collision strips around it. Elastic cushioning effect, and concentrate the impact force and transfer it to the force-collecting column, and then squeeze the energy-absorbing bag to achieve secondary buffering, which can effectively offset the external impact force, and is not easy to cause vibration to the ammeter body itself. The self-heating phenomenon is triggered during the extrusion process of the force-collecting column, and the heat is transferred to the thermal separation rod to promote its separation action, and then rely on the magnetic repulsion of the static magnetic ring on the early-warning film to force it to expand outward for early warning. It prompts the impact part, and at the same time, the expanded early warning film can increase the buffer barrier when facing the same impact, thereby improving the anti-impact ability of the ammeter.

Description

technical field [0001] The invention relates to the technical field of ammeters, in particular to a self-warning anti-collision ammeter. Background technique [0002] Ammeter refers to the instrument used to measure the current in AC and DC circuits. In the circuit diagram, the symbol for the ammeter is "circle A". The current value is in "A" or "A" as the standard unit. [0003] The ammeter is made according to the action of the current-carrying conductor in the magnetic field by the force of the magnetic field. There is a permanent magnet inside the ammeter, which generates a magnetic field between the poles. There is a coil in the magnetic field. There is a hairspring spring at both ends of the coil. Each spring is connected to a terminal of the ammeter. The spring and the coil are connected by a rotating shaft. On the front of the ammeter, there is a pointer. When a current flows, the current passes through the magnetic field along the spring and the rotating shaft, ...
