Description

Linear type pullswitch

Technical field

This utility model relates to a kind of switch, specifically a kind of illuminating Linear type pullswitch.

Background technology

Common pullswitch includes box body, electrode copper sheet, ratchet, elastic copper sheet, thumb wheel iron plate, back-moving spring, rotating shaft and bracing wire, power supply one end is connected with electrode copper sheet one end, the other end contacts with copper forks piece, copper forks piece can with the bending copper sheet end thereof contacts being disposed on ratchet, connecting stay wire on thumb wheel iron plate, by pulling bracing wire to make thumb wheel iron plate drive ratchet to rotate around rotating shaft, when pull bracing wire make pawl wheel arrive bending copper sheet thereon contact with elastic copper sheet time, circuit ON, illuminating lamp is bright; Pulling on bracing wire, make ratchet be rotated further by bending copper sheet thereon when not contacting with elastic copper sheet, circuit disconnects, and illuminating lamp does not work. Pullswitch principle in the market is all based on this principle, is mainly characterized by ratchet and rotates around rotating shaft. This pullswitch, due to easy to operate, uses safety, it is simple to distance and multi-faceted open or close control, has some application scenarios being difficult to replace, and has vast user, deeply by people, the liking of special middle-aged and elderly people. But pullswitch in use still has problems with: one is that ratchet rotates frequently and contacts, elastic copper sheet easily loosens, can draw close toward electrode copper sheet at leisure, even if ratchet does not have bending copper sheet sometimes, elastic copper sheet also can contact with electrode copper sheet, circuit turn on automatically, illuminating lamp is bright, thus there will be the situation that illuminating lamp does not close; Two is that ratchet frequently rotates, add back-moving spring be heated easily causing reset lost efficacy, make thumb wheel iron plate can not drive pawl wheel, pullswitch is caused to scrap, copper splinter frequently switches on and electric current Joule heat, causes shell fragment annealing, fatigue damage, fracture, causes service life short; The copper sheet being pullswitch again is limited by the structure, and copper sheet bending copper sheet is little with elastic copper sheet contact area, and inapplicable big illuminated uses, and uses only as small-power Lighting control.

Utility model content

Problem existing for pullswitch in prior art, this utility model provides a kind of compact conformation, easy to operate, safe and reliable, and the Linear type pullswitch of applicable larger current work.

This utility model to solve technical problem and be adopted the technical scheme that: described Linear type pullswitch includes cylinder and the cover being movably connected with cylinder upper end, described cylinder lower end is provided with cylinder base, cylinder base is relatively set with lower conducting strip, lower conducting strip is connected with lead-in wire respectively, inner core it is provided with in cylinder, inner core is provided with stopper rod, stopper rod can slide up and down at inner core, stopper rod upper end is provided with spring, stopper rod upper end is connected with bracing wire, it is drawstring through cover, described stopper rod lower end is fixedly installed the elastic clipping strip taken the shape of the letter U and upper conducting strip, stopper rod both sides are provided with and elastic clipping strip can be made to shrink the groove made a concession, described inner core sidewall is provided with open slot, described open slot bottom is lower guide channel, top is upper rail, the cylinder inboard wall relative with elastic clipping strip is provided with clamping slot, clamping slot has and the guiding surface of the claw slopes which match on elastic clipping strip.

Work process of the present utility model is: firmly pull up when straining at line, stopper rod moves upward, stopper rod moves upward and compresses spring and drive elastic clipping strip and upper conducting strip to move upward, now two claws on elastic clipping strip extend in clamping slot in the presence of a tensile force, now go up conducting strip to separate with lower conducting strip, down circuitry, illuminating lamp is closed, continue up tension bracing wire, stopper rod moves upward and continues compression spring and drive elastic clipping strip and upper conducting strip to move upward, elastic clipping strip is under the oblique spigot surface effect of clamping slot, when its two claw is withdrawn into upper gathering sill a point from clamping slot, under the ab section cambered surface effect of pulling force and upper gathering sill, stopper rod relatively rotates, claw pivot offset certain angle thereon (10 �� of 15 �� of purposes are to make the claw on elastic clipping strip avoid clamping slot in subsequent motion) is made to arrive b point position (stop position), now unclamp bracing wire, stopper rod is downward rapid movement under the recovery elastic force effect of spring, thus elastic clipping strip can be driven quickly to fall back in lower gathering sill along bc section and the cd section of lower gathering sill, so that claw is avoided clamping slot in decline and is returned to original position (as shown in Figure 3), conducting strip is made to contact with lower conducting strip, circuit ON, illuminating lamp is bright.

This utility model utilizes one to move two quiet conducting strips contact and disconnections, and utilize the effect of the gathering sill up and down of elastic clipping strip, realize the cyclic process of circuit ON �� disconnection �� disconnection locking �� disconnection �� connection, circuit utilizes elastic clipping strip to lock when disconnecting, utilize during connection and assume diamond in shape or the effect of upper gathering sill of parallelogram, realize Rapid reset and make circuit ON, it is compact conformation not only, manufacture easy to use, ruggedness is strong, safe and reliable, and long service life, it is suitable for big illuminated and controls to use.
