Abstract

The utility model belongs to an explosion proof electric torch which is used in an explosive and flammable environment, the purpose is to design an explosion proof electric torch with the advantages of reducing cost, extending service life and having safe performance according to the relevant explosion proof standard of China. The main structure of the utility model is that a cuboid accumulator 8 is assembled in a cuboid casing 7, and a press spring piece 13 in a rear sealing cover box 10 and a bulge in a rear cover box 11 form a press type switch; the utility model has the advantages of small internal resistance, long service life and low cost, the phenomena of rotation of the electric torch and corrosion of a battery are avoided, the maintenance is reduced, and the closed rubber accumulator 8 with 4.5V and 1.2AH is used as power source.

Description

Explosion-proof electric torch using sealing gum accumulator

The utility model belongs to the explosion-proof torch of the gluey battery type of a kind of sealing that uses in inflammable and explosive environment.

In original technology, anti-riot torch is operation in inflammable and explosive place, and possessing safe dc lighting device, used explosion-proof torch is a power supply with common 1 trumpeter's battery at present, has two joints (3V), 3 joints (4.5V) and 4 joint (6V) batteries to form power supply, because of the torch pond is can not recharge use after the disposable discharge, along with prolong service time, illuminance is lower, and improper use, battery is perishable, causes damaging or corroding explosion-proof torch.Use cost expense height, an annual explosion-proof torch need because flashlight switch exposes outside, easily be dyed by greasy dirt during use with 50～80 yuan common torch pond, causes malfunctioning switch.

The purpose of this utility model is to solve above-mentioned weak point of the prior art, develop the explosion-proof torch of the gluey battery type of a kind of sealing, design by GB3836.1-83 " explosive atmosphere with the general requirement of electric apparatus for explosive atmospheres " and GB3836.2-83 " explosive atmosphere with electric apparatus for explosive atmospheres flameproof electrical apparatus " d " ", reach low-cost, increase the service life the purpose that performance is safe and reliable.

Technical solution of the present utility model is:

Housing 7 anterior assemblings are with small electric bulb 5, middle hamper 4, the skull box 1 of axis symmetry, assembling condenser 3 and eyeglass 2 in the skull box 1, the assembling of housing 7 rear portions is with the rear seal-cover box 10 and the back hamper 11 of axis symmetry, be characterized in: the gluey battery 8 of sealing that is the housing 7 interior assembling cuboids of cuboid, making leaf spring 13 in the rear seal-cover box 10 and back hamper 11 projecting inward composition push switch, back hamper 11 is with thread forms and 10 assemblings of rear seal-cover box.

Also be equipped with charging hole 14 and charging indicator light 12 in the rear seal-cover box 10.

Housing 7 and 4.5V, filling cushion pad 9 between the sealed cell 8 of 1.2AH.

Description of drawings of the present utility model is as follows:

Fig. 1 is the overall structure front view.

Fig. 2 is the overall structure vertical view.

Number in the figure is described as follows:

1-skull box, 2-eyeglass, 3-condenser, hamper among the 4-, 5-small electric bulb, 6-electric bead block, 7-housing, 8-sealed cell, 9-cushion pad, 10-housing rear seal-cover box, hamper behind the 11-, 12-charging indicator light, 13-making leaf spring, the 14-hole of charging.

Embodiment of the present utility model is described as follows:

See shown in the accompanying drawing, pack in the housing 7 cuboid sealed cell 8 and cushion pad 9, hamper 4 in the housing 7 front end spiral marking connections, hamper 4 assemblings in eyeglass 2 and condenser 3 usefulness skull boxes 1 spiral marking connection, housing 7 rear ends link housing rear seal-cover box 10 by explosive-proof sealed, hamper 11 behind housing rear seal-cover box 10 spiral marking connections, assembling charging indicator light 12, making leaf spring 13 and charging hole 14 in rear seal-cover box 10, back 11 projecting inward cooperations with making leaf spring 13 of hamper are formed switch.

When needs were used torch, hamper 11 after the turn, making leaf spring 13 pressurizeds energising in the switch, and small electric bulb 5 is luminous.When not needing electricity, the moving back of derotation hamper 11, making leaf spring 13 outages.When needs charged, the 4.5V charger of selling on the available markets carried out.

The utility model has the advantages that:

Simple in structure, owing to adopt 4.5V, 1.2AH seals gluey battery 8 as power supply, so it is little to have an internal resistance, self-discharge rate is low, and the life-span is long, generally uses 3～5 years, has avoided more maintenance, in use, the discharge-rate height, price is low, about 20 yuan every. This Outer because housing 7 employing cuboids have avoided torch to be placed on the possibility of rolls on the floor, use for a long time economical and practical. The utility model does not use for a long time, need not take out battery, and battery never degenerates, and does not corrode housing.
