Rear covering plate of fire-fighting base station box

Abstract

The invention provides a rear covering plate of a fire-fighting base station box. The rear covering plate of the fire-fighting base station box belongs to the field of fire-fighting base station boxes. A shakeproof stick can be used for indicating whether the fire-fighting base station box is excessively vibrated and impacted or not, and inner pearl wool can protect a circuit board and wiring, so that the fire-fighting box can maintain a normal function when being shocked during a fire disaster; and a rear cover and the base station box can be assembled and disassembled simply and conveniently, so that the maintenance efficiency can be improved favorably. The rear covering plate of the fire-fighting base station box comprises a cover plate, a clamping plate and a fixing bottom plate. The clamping plate is arranged on the upper end of the cover plate, and is provided with an inwards inclined angle relative to the cover plate; the fixing bottom plate is arranged on the lower end of the cover plate, and is inwards vertical relative to the cover plate; a lock hole through hole and bolt through holes are formed in the cover plate; the shakeproof stick is pasted on the outer surface of the cover plate; the pearl wool is pasted on the inner surface of the cover plate; gaps are reserved for positions, corresponding to the lock hole through hole and the bolt through holes, of the pearl wool; a clamping slot is arranged on the clamping plate; and a fixing hole is formed in the fixing bottom plate.

Description

technical field [0001] The invention belongs to the field of elevator fire-fighting base station boxes, and in particular relates to a rear cover plate of a fire-fighting base station box. Background technique [0002] The fire-fighting base station box of the elevator is used to install and fix the elevator fire-fighting start switch panel, and it is a closed box buried in the wall; after a fire occurs, the firefighters press the emergency landing button to lower the fire-fighting elevator to the first floor, and the fire-fighting switch After it is turned on, all calls will be cancelled, and the designated elevator will immediately return to the designated landing, and the elevator will open its door and stand by for firefighters. The back cover of the fire base station box is used to cover the back of the fire base station box to protect the circuit board and wiring inside the box, but the connection between the existing back cover and the fire base station box is complic...

AI Technical Summary

Problems solved by technology

The back cover of the fire base station box is used to cover the back of the fire base station box to protect the circuit board and wiring inside the box, but the connection between the existing back cover and the fire base station box is complicated, and once the fire base station box fails, it will Inconvenient; due to the severe vibrations associated with a fire, the existing back cover does not have a shockproof function, neither can indicate the degree of shock of the box itself, nor can it buffer the impact of vibration on the internal circuit board and wiring
