Abstract
An electromagnetic switch of the portable fire extinguisher relates to an electromagnetic switch, in particular to an electromagnetic switch with simple structure and convenient installation. While using, the portable fire extinguisher is not needed to be changed. The implementing scheme of the utility model is following: by the bolt the frame is connected with the electromagnet comprised of a shell, a coil, an iron core and a spring, a dustproof cap is arranged on the shell. The chute of iron core, a top pillar, a spring and an outer casing comprise of a unidirectional mobile mechanism. The lower end of iron core is provided with an adjusting bolt and a locknut. The rotation of iron core is limited by a locating stud cooperated with a vertical chute on the iron core. A safety cover is arranged on the frame. While using, the electromagnetic switch is connected with the lifting handle of the portable fire extinguisher by the frame, after the power supply is being switched on, the electromagnetic switch acts and the fire extinguisher is opened. When necessary, the fire extinguisher can be opened by extracting the safety cover and pressing the press handle to carry out the fire extinguishing work. The utility model can be installed without more change to the portable fire extinguisher, and the use is very convenient.
Description
Technical field: the utility model relates to the electromagnetic switch of a kind of electromagnetic switch, particularly a kind of supporting hand fire extinguisher.
Background technology: " motor vehicle centralized Control extinguishing device " utility model patent (patent No.: ZL00266323.6) disclose a kind of structure of motor vehicle extinguishing device, requirement is supporting electromagnetic switch simple in structure, easy for installation on hand fire extinguisher, to realize Long-distance Control.
Summary of the invention: the purpose of this utility model is to provide a kind of simple in structure, can be installed in the electromagnetic switch on the hand fire extinguisher easily, and need not hand fire extinguisher is done bigger change.The utility model embodiment is as follows: the electromagnet that support is formed by bolt and shell, coil, iron core, spring links together; The shell upper end is provided with dust cap, and draws lead; Skewed slot on the iron core and fore-set, spring, overcoat are formed a unidirectional travel mechanism; The adjustment bolt and lock nut is equipped with in lower end unshakable in one's determination; Alignment pin is housed on the shell, cooperates with elongated slot on the iron core and limit rotation unshakable in one's determination; Protecting cap is rack-mount.Link together by the carrying handle of support with electromagnetic switch and hand fire extinguisher during use, connect power supply, the electromagnetic switch action can be opened fire extinguisher.Also can extract protecting cap in case of necessity out directly pushes down pressure handle and opens fire extinguisher and carry out fire-fighting work.Characteristics such as that this utility model has is simple in structure, with low cost, simple installation, need not that hand fire extinguisher is done bigger change can install.
Description of drawings:
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is that the utility model is installed in the schematic diagram on the hand fire extinguisher.
Fig. 3 is an electrical schematic diagram of the present utility model.
Among the figure 1, support 2, adjust bolt 3, locking nut 4, bolt 5, shell 6, coil 7, unshakable in one's determination 8, lead 9, dust cap 10, spring 11, alignment pin 12, protecting cap 13, fore-set 14, spring 15, overcoat 16, lead sealing 17, pressure handle 18, carrying handle
The specific embodiment: as shown in drawings, support (1) links together by bolt (4) and shell (5); Dust cap (9) is equipped with in the upper end of shell (5), and draws lead (8); Skewed slot and fore-set (13), spring (14), the overcoat (15) of (7) unshakable in one's determination upper end are formed unidirectional travel mechanism; (7) lower end unshakable in one's determination is equipped with and is adjusted bolt (2) and locking nut (3); The vertical elongated slot of (7) lower end unshakable in one's determination and the rotation of alignment pin (11) the engagement limits iron core (7) on the shell (5); Protecting cap (12) and lead sealing (16) are housed on the support (1).The electromagnetic switch of during use combination being finished is installed on the carrying handle (18) of hand fire extinguisher, by rotation adjust bolt (2) regulate with pressure handle (17) between the gap, mix up the back and fix with locking nut (3).The effect of protecting cap (12) is to prevent that accident from touching pressure handle (17) and making the fire extinguisher misoperation.Connect power supply behind the vehicle fire, electromagnetic switch action can promote pressure handle (17) and open fire extinguisher and carry out fire-fighting work, also can extract protecting cap (12) in case of necessity out and directly push down pressure handle (17) and open fire extinguisher.
