Spray head expansion and control device

Abstract

The invention discloses a spray header expansion and control device comprises a motor, a first mounting plate, a second mounting plate, a spray header, a support column and a regulating tube; a lead screw is driven to rotate by using the rotation of the motor to realize that a moving block moves downward on the lead screw, thereby pushing a push rod to move downward to drive the second mounting plate and the first mounting plate to move downward, the regulating tube is driven to move downward during the descent process of the second mounting plate, the regulation of the height of the regulating tube is realized, the purpose of adjusting the height of the spray header is further realized, and different height requirements of spray header are met under different conditions; the first mounting plate drives a sealing rubber ring to move downward to seal a joint between the regulating tube and a drooping tube during the descent process of the first mounting plate, spray header height adjustment is convenient and fast, and manpower pulling of the regulating tube is not required; and the stability of the moving block moving on the lead screw is improved by arranging the support column.

Description

technical field [0001] The invention relates to an adjustment device, in particular to a telescopic adjustment device for a sprinkler head. Background technique [0002] The fire sprinkler is used in the fire sprinkler system. When a fire breaks out, the water is sprayed out through the splash plate of the sprinkler to extinguish the fire. At present, it is divided into a pendant sprinkler, a vertical sprinkler, a common sprinkler, and a side wall type. Sprinklers, etc.; [0003] At present, as a part of emergency fire fighting equipment, sprinkler heads are installed in many buildings. The positions of existing sprinkler heads are generally fixed and do not have adjustment devices, so the height of sprinkler heads cannot be adjusted to meet Different situations require different heights of the sprinkler head, and at the same time, the height adjustment of the existing sprinkler head generally relies on manual adjustment, which wastes a lot of manpower and the adjustment ef...

Problems solved by technology

[0003] At present, as a part of emergency fire fighting equipment, sprinkler heads are installed in many buildings. The positions of existing sprinkler heads are generally fixed and do not have adjustment devices, so the height of sprinkler heads cannot be adjusted to meet Different situations require different heights of the sprinkler heads. At the same time, the height adjustment of the existing sprinkler heads generally relies on manual adjustment, which wastes a lot of manpower and the adjustment efficiency is low.
