Abstract

The utility model discloses a novel pull wire indication switch which can indicate the function of power on and off. The original rotary switch is changed into a top-lift switch. When a pull wire 13 is pulled downwards, an execution rod (1) move downwards. The execution rod (1) is automatically locked under the action of a clamping thread (2) and a spring (3). A metal sheet (14) and an electrode contact 4 are disconnected, and the switch is in a closed state. An indication mark rod (11) is bounced upwards to show that a circuit is disconnected. When the pull wire is pulled again, the execution rod (1) move upwards, and the metal sheet (14) respectively contacts the electrode contacts 4, 5. The circuit is switched on, and the switch is in an open state. The indication mark rod (11) drops to show that the circuit is switched on. The utility model has the advantages of simple structure, convenient processing and installation, safe use and strong practicability.

Description

The novel guy indicator cock

A kind of backguy indicator cock relates to the low-voltage electrical technical field, is applicable to that the circuit such as domestic lighting about 220 volts use.

The pulling switch of Chu Shouing is used in each family, shop, factory, office etc. widely and locates in the market, though easy to use, have the weak point of the following aspects:

1, switch does not have the deixis of power on/off, and when having a power failure, you can't judge whether electric light closes or open like this, might cause because of in the family nobody the time, incoming call and cause waste.

2, general pulling switch, because of the part that is tied to pull line directly links with circuit, so in case backguy broken, relatively danger when fastening again, generally old man, child, women and the people that do not have electricity consumption general knowledge can't go to finish the work that is tied to pull line.

What 3, present switch was general all is with on the screw fixings chock on the wall, and the work formality is loaded down with trivial details, and influence job schedule, is also breaking because of switch at ordinary times to common people, and more renew switch makes troubles.

The purpose of this utility model provides a kind of novel guy indicator cock, by this switch, the power on/off Warning Mark is arranged, the unimpeded or disconnection of indication circuit.

In order to realize above-mentioned target, the utility model proposes a kind of novel guy indicator cock.Novel switched have a power on/off Warning Mark, the Drawing switch backguy both can make circuit turn-on or disconnection, drive Warning Mark simultaneously and do 90 ° rotation, indication circuit is unimpeded when Warning Mark is sagging, when Warning Mark and switch backguy at an angle of 90 the time indication circuit disconnect.This switch to fasten line part very safe, stay thimble is fixed on the plastics, with the circuit part insulation, and line fastening ring is exposed at switch external, need not open switch enclosure cover when fastening line, anyone can fix the switch backguy easily and safely like this.The installation switch is very convenient, only need to nail on one piece of nail (head of a nail exposes metope 0.5cm and gets final product) in the place that switch is installed, the extension hole that to close then (big hole) is filled in the head of a nail, switch is whole toward drop-down, switch just has been stuck in the head of a nail, the whole erection process is short, brings convenience to installation personnel, thereby has reached that volume is little, simple in structure, installation and processing convenient, generous, practical and purpose of safety very handsome in appearance.

The full drawings and Examples of knot are described in further detail the utility model below.

Fig. 1 is an outside drawing of the present invention.

Fig. 2 is that Fig. 1 lid is opened schematic diagram.

Fig. 3 is the structural representation (specification digest accompanying drawing) of backguy indicator cock.

Fig. 4 is Fig. 3 parts and fundamental diagram.

Fig. 5 is circuit and switch fundamental diagram.

Warning Mark work sheet when Fig. 6 is power on/off.

Fig. 7 is the fixing work sheet on the wall of switch.

Fig. 1 is a novel guy indicator cock external view.

Fig. 2 is that novel guy indicator cock lid is opened schematic diagram: after being suspended to switch enclosure on the wall, can open switch enclosure cover 18 pushing away on the lid 18, cause has the effect of slideway 17, can make the lid activity freely, the power positive cathode line is received on the binding post (screw) 6,7 to get final product again.

Fig. 3 is a novel guy indicator cock structural representation:

In structural representation shown in Figure 3, the execution bar 1 of switch mainly plays the effect of conducting and open circuit, also promote simultaneously the critical piece of Warning Mark bar 11 motions, stay thimble 10 also is fixed on the bottom of this execution bar 1, backguy 13 bolts are on stay thimble 10, full bar is formed by the bakelite plastic processing of insulation, is the major part of this switch.Carry out bar 1 and also be fixed with card silk 2, mainly make to carry out and realize self-locking when bar 1 moves up and down, be enclosed within the spring of carrying out on the bar 13 and play the effect that bar 1 resets of carrying out that makes,

stationary electrode contact

4,5, under the effect of spring 15, by sheet metal 14 respectively with

external electrode

6,7 link to each other, after external cord penetrated from external cord hole 8, be fixed on external electrode 6, on 7, fixing with screw 19, hanging hole 9 designs for floatless switch, for ease of bolt backguy rope, in respect of stay thimble 10, also design has the Warning Mark bar 11 of expression power on/off function at switch enclosure lower end box peripheral hardware, Warning Mark bar 11 epimeres are fixed on the substrate 12 by axle 20, Warning Mark bar 11 epimeres are provided with hook 21, so that when 12 one-tenth 90 ° of marker post 11 and substrates, prevent that marker post 11 is sagging, all parts on the novel guy indicator cock all are fixed on the main body substrate 12, have formed complete switch.

Fig. 4 is parts and the fundamental diagram shown on Fig. 3:

Fig. 4 A is the main diagrammatic sketch that switch is carried out bar 1, Fig. 4 B, self-locking work schematic diagram when 4C is work:

When backguy 13 when drop-down, carry out bar 1 and move down, move downwards curved groove 17 in the lower end of card silk 2, because the effect of mechanisms in the groove 17 makes and carries out bar 1 self-locking (Fig. 4 C), present and become 90 ° angle with switch, indication circuit disconnects, and makes switch be in "off" state.When pulls wire 13 again, to carry out bar 1 and be released, and restore to the original state (Fig. 4 B), Warning Mark bar 11 is carried out bar 1 when sagging and is kept normality, and the indication circuit conducting makes switch be in "open" state.

Fig. 5 is circuit and switch fundamental diagram:

Move down when carrying out bar 1, sheet metal 14 disconnects with electrode contacts 4, circuit disconnects, switch is "off" state, moves when carrying out on the bar 1, and sheet metal 14 contacts with

electrode

4,5 respectively, circuit turn-on, switch is "open" state, and the effect of spring 15 is to keep sheet metal 14 to have elasticity, can keep the effect that contacts with

electrode contacts

4,5 again.

Warning Mark work sheet when Fig. 6 is the energising outage:

When Warning Mark bar 11 is sagging, carries out bar and keep normality, indication circuit conducting, both switch was outer in "open" state, moved down when carrying out bar 1, promoted 11 motions of Warning Mark bar, present when becoming 90 ° angle with switch, indication circuit disconnects, and both switch was in "off" state.

Fig. 7 is switch regular worker mapping:

The head of a nail is passed from the big hole of hanging hole 9, and with switch drop-down (because the head of a nail blocks the duck eye of hanging hole 9), switch was both fixing on the wall then.
