Description

Adjustable mounting bracket for alarm

Technical Field

The utility model relates to a mechanical tool technical field, concretely relates to adjustable installing support is used to alarm.

Background

In the field of petrochemical instrument installation, especially in the installation of combustible and toxic alarms, an alarm installation support is indispensable and has wide application. In the installation of combustible and toxic alarms, the installation height of the alarm is strictly regulated in safety, the regulation requirement is between 30cm and 60cm, the alarm can be regulated within the regulation range according to the actual condition, combustible gas is high in density and gathers at the lower part of air when leakage occurs in practice, so that the lower the installation height of the alarm within the regulation range is, the better the alarm is, but in rainy and snowy weather, the damage caused by the fact that the alarm is submerged by accumulated water is avoided, and the installation height of the alarm needs to be regulated to the highest height within the regulation range before the rainy and snowy weather comes. For this reason, the height of the alarm needs to be adjusted frequently. However, the existing alarm installation mode in the industry is to install the alarm on a cylindrical vertical rod support, when the installation height of the alarm needs to be adjusted, the alarm can only be detached and installed again, the operability is poor, and the operation is time-consuming and labor-consuming.
