Abstract

The utility model provides a lock-type switch. The switch comprises a lock core, a housing and a base plate. The lock core is composed of a lock core body and a rotor. The rotor is provided with a lock hole. A key is matched with the lock core. A strip-shaped rotating shaft is fixed at one end of the rotor, and a rotating arm is fixed on the rotating shaft. The housing is fixed on the base plate, and the lock core is exposed by a lock core hole on the top of the housing. An inlet wire hole and an outlet wire hole are disposed on a side face of the housing. Two parallel metal reeds are fixed inside the housing. Each of the metal reeds is provided with a metal contact, and the two parallel metal reeds are respectively connected with an input terminal and an output terminal. The positions of the two parallel metal reeds are at two sides of the outer end of the rotating arm. The metal contacts are isolated by the rotating arm. When rotated in place, the rotating arm is far away from the metal contacts, and the two metal reeds are connected. Each of the four corners of the bottom plate is provided with a fixing hole for fixation. The beneficial effects of the utility model are that the principles of a lock are applied to an electric switch, so that the safety of the electric switch is improved.

Description

Lock switch

Technical field

The utility model relates to a kind of switch, particularly relates to a kind of lock switch.

Background technology

General switch is all to facilitate that to use be object, but for the crowd as children, awareness of safety is low, and careless use electrical appliance switch may cause danger, and the utility model is exactly to utilize the principle of lockset to solve this problem.

Utility model content

The technical solution of the utility model: a kind of lock switch, is characterized in that: it is to consist of lock core, shell, base plate; Lock core consists of lock core body, rotor, has lockhole on rotor, and lock core is furnished with the key of coupling, and the rotor other end is fixed with strip rotation axis, is fixed with cursor on rotation axis; Shell is fixed on base plate, directly over shell, having lock core hole can make lock core expose, shell side has input line hole and output line hole, enclosure is fixed with two parallel metal reeds, all respectively has hard contact on metal spring leaf, and two parallel metal reeds are connected to respectively input and output, the position of two parallel metal reeds is end points both sides outside cursor, cursor isolating metal contact away from hard contact, just can be connected these two metal spring leafs when cursor forwards to; On base plate, four angles have fixing hole in order to fixing.

Above-mentioned said lock switch is all that high-strength insulation plastics form except enclosure is fixed with two lock core, key, shell, base plates parallel metal reed in its structure.

Superiority of the present utility model: the utility model on electrical appliance switch, is improved the fail safe of electrical appliance switch the principle utilization of lockset.

Accompanying drawing 1 is surface structure schematic diagram of the present utility model;

Accompanying drawing 2 is the internal structure schematic diagram when switch connection of the present utility model;

Accompanying drawing 3 is the internal structure schematic diagram when switch access failure of the present utility model;

The end view that accompanying drawing 4 is lock core of the present utility model;

Wherein: the 1st, lock core, the 2nd, shell, the 3rd, base plate, the 4th, lock core body, the 5th, rotor, the 6th, lockhole, the 7th, rotation axis, the 8th, cursor, the 9th, lock core hole, the 10th, input line hole, the 11st, output line hole, the 12nd, fixing hole, the 13rd, metal spring leaf, the 14th, hard contact, the 15th, input, the 16th, output, the 17th, key.

Embodiment

As accompanying drawing: a kind of lock switch, is characterized in that: it is to consist of lock core 1, shell 2, base plate 3; Lock core 2 consists of lock core body 4, rotor 5, has lockhole 6 on rotor 5, and lock core 1 is furnished with the key 17 of coupling, and rotor 5 other ends are fixed with strip rotation axis 7, are fixed with cursor 8 on rotation axis 7; Shell 2 is fixed on base plate 3, directly over shell 2, having lock core hole 9 can make lock core 1 expose, shell 2 sides have input line hole 10 and output line hole 11, shell 2 inside are fixed with two parallel metal reeds 13, on metal spring leaf 13, all respectively there is hard contact 14, two parallel metal reeds 13 are connected to respectively input 15 and output 16, the position of two parallel metal reeds 13 is in the outer end points of cursor 8 both sides, cursor 8 isolating metal contacts 14, when forwarding to, away from hard contact 14, just these two metal spring leafs 13 can be connected cursor 8; On base plate 3, four angles have fixing hole 12 in order to fixing.

Above-mentioned said lock switch is all that high-strength insulation plastics form except shell 2 inside are fixed with two lock core 1, key 17, shell 2, base plates 3 parallel metal reed 13 in its structure.

Using method of the present utility model is: when mounted input line is connected on to input 15 through input hole 10, output line is connected on output 16 through delivery outlet 11, while opening switch, key 17 is inserted to lockholes 6 rotations and make cursor 8 contact and connect circuit with metal two contacts 14, the used time is not rotated key 17 that to initial condition, pull up be to have closed switch.

Claims
