CS267778B1 - Mounting rod for tahki fire detectors - Google Patents

Abstract

The mounting rod is designed for mounting and dismounting light fire detectors. It is foldable and its reach can be increased by inserting an extension piece. There are two pivoting mounting jaws and two ejector arms on the head. The jaws are operated by a lever handle. To secure the jaws with the detector inserted, the lever is equipped with a pin* that fits into the latch cutout and a release button. The ejector arms are operated by a lever handle. The jaw spacing and the arm displacement are adjustable.

BACKGROUND OF THE INVENTION [0002] The present invention relates to a mounting rod for heavy fire detectors of the MHG 101, MHG 103, MHG 301, MHG 501, MHG 304 and MSK 101 types. Send the produced types of disassembly rods MHY 704, MHY 506, MHY 507 nle are suitable for the purpose of simple and quick assembly and disassembly of fire detectors of the mentioned types from 1 outlets. In addition to these manufactured types, at the level of ZN the proposed irreversible hurts, which in practice did not spread from the complicated or unprepared or unprepared (hurdles), are hurting.

The aforementioned drawbacks are eliminated by the mounting rod of the invention, the principle of which is that an aluminum rod, which is normally equipped with servo-working elements, is mounted on the folding device. A head is attached, on which two hinged mounting rests are pivotably mounted and two extendable discharge arms. Both the arms and the arms are controlled by a lever wire transmission. Returning the readout and the pressure rays to the base position securing the oeet springs. The control levers have been read and the raalen consists of a lever handle, a mounting sleeve, and a knob on the adjusting mechanism formed by the rotary shaft and the double latches. The lever on the control panel is fitted with a latch, a cradle, and a spring-loaded button to clamp the levers and read in the working position. The extension rod of the mounting rod is complemented by bowden cables, terminated by connecting bolts and nuts.

The mounting rod of the invention is preferably used in the benders or the fire detectors.

BRIEF DESCRIPTION OF THE DRAWINGS In the accompanying drawings, an object of the invention is shown, wherein in FIG. FIG. 2 is a cross-sectional view of the mounting head, and FIG. 3 is a sectional view of the extension rod length. In Fig. 4, the lever-like gripper is shown.

On the aluminum mounting folding rod 1 supplied by the maintenance worker to test the function of the fire detectors, a head 2 is mounted, on which are mounted two pivot catches 16, 2 and two discharge pusher pivotally, rotatably about the pivot. arms J>, ¢. The wheelbase can be readjusted and the buckling force can be adjusted by an adjusting mechanism by rotating the shaft 22. For better catching of the speaker, they are readily coated with a soft rubber, similar to the surface of the displacement arms. The reversibility of the read-out to the basic position is provided by the vinegar springs 2 with four shifting axes J. The lever on the actuator consists of a handle 21, a fastening sleeve 22 and a adjuster of the wheelbase, consisting of a shaft 12, and a sprocket into which the shaft is rotated. latches 12 and J4 engage. In order to cushion the reader in the working position, i.e., punch to the readers, the lever is complemented by a pawl 22 engaging its cut-out as many as 22. The pawl is operated by a peeling button 28 and a spring 22. JJ, the sleeve 10 and the same rotary shaft 12, the pinion gear 11 and the pawls 12, 16 as in the previous lever, but these can be at the regulating position of the arm. The extension rod of the folding rod is complemented by boudeners 2έ, 2Z, fixed in the partition 1 / and terminated by connecting nuts and screw-ml 18, 12-

To remove the detector from the pMtke:

Push the head 2 »» onto the fire detector. Press the lever 21 to read jj, 4 press against the detectors, and the latch 22 latches for how much 22 · Press »the second handleThe calipers will eject the discharge arms 2, 2 and remove the detector from pMtice. Ramlen running is about 25-30 mm.

The detector is pushed in as follows:

The detector is inserted into the g head so that the detector projection directs towards the marking of the discharge arm. Pressing handle 21 locks latch 22, 81® J® detector closes.
