Embodiment Construction

[0026] The shells of existing explosion-proof manual fire alarm buttons often use plastic as the shell, and antistatic agents are sometimes added to plastics in order to reduce the volume resistivity. However, these measures have not fundamentally reduced the existing explosion-proof manual fire alarm buttons. volume resistivity. The explosion-proof manual fire alarm button of the present invention adopts an iron shell, and the overall structure of the iron shell is simple and practical, and can effectively realize the grounding, so that the volume resistivity of the explosion-proof manual fire alarm button is always kept at a low level, and even used The volume resistivity is 0.

[0027] The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0028] Such as figure 1 Shown is a schematic view of the internal structure of the bottom shell of the explosion-proof manual fire alar...

Abstract

The invention discloses an explosion-proof type manual fire alarm button comprising a shell. The shell comprises a bottom shell and a front shell buckled together; and both the bottom shell and the front shell are made of metal materials. By adopting iron shell, the explosion-proof type manual fire alarm button overcomes the defect that the plastic shell can not effectively reduce the volume resistivity in the prior art and ensures effective shielding protection on the alarm circuit.

Description

technical field [0001] The invention relates to a fire alarm technology, in particular to an explosion-proof manual fire alarm button. Background technique [0002] With the rapid development of industry and the rapid promotion and application of polymer materials, the wide application of some high resistivity polymer materials such as plastics, rubber and other products and the high speed of modern production processes make static electricity accumulate to a very high level. degree. [0003] On the other hand, the production and use of electrostatic sensitive materials, such as light oil, gunpowder, solid-state electronic devices, etc., as well as the frequent movement of staff and the inevitable friction in production, etc., the enterprise sector is subject to electrostatic hazards, causing casualties and property The possibility of loss is increasing. In view of the fact that electrostatic hazards will cause quite serious consequences and losses, how to design a safe and...
