Abstract

The invention discloses a safety switch lock. The safety switch lock is characterized by consisting of a lock core, a shell and a bottom plate, wherein the lock core consists of a lock core body and a rotor; the rotor is provided with a lock hole; the lock core is provided with a matching key; the other end of the rotor is fixedly provided with a strip-shaped rotating shaft; the rotating shaft is fixedly provided with a rotating arm; the shell is fixedly arranged on the bottom plate; a lock core hole is formed just in the top of the shell and enables the lock core to expose; a side face of the shell is provided with an input line hole and an output line hole; two parallel metal reeds are fixedly arranged in the shell, are provided with metal contacts respectively, and are connected with an input end and an output end respectively; the positions of the two parallel metal reeds are on the two sides of the outer end of the rotating arm; the metal contacts are isolated by the rotating arm; when the rotating arm is turned in place, the rotating arm is away from the metal contacts, so that the two metal reeds can just be communicated; the four corners of the bottom plate are provided with fixing holes for fixation respectively. The safety switch lock has the advantage that the safety performance of a switch of an electrical appliance is improved by utilizing the principle of the lock on the switch of the electrical appliance.

Description

Safety open shuts

(1) technical field

The present invention relates to a kind of switch, particularly relate to a kind of safety open and shut.

(2) background technology

General switch is all for the purpose of easy to use, but for the crowd as children, awareness of safety is low, and careless use electrical appliance switch may cause danger, and the present invention utilizes the principle of lockset to solve this problem.

(3) summary of the invention

Technical scheme of the present invention: a kind of safety open shuts, and it is characterized in that: it is made up of lock core, shell, base plate; Lock core is made up of lock core body, rotor, and rotor has lockhole, and lock core is furnished with the key of coupling, and the rotor other end is fixed with strip rotation axis, and rotation axis is fixed with cursor; Shell is fixed on base plate, having lock core hole directly over shell can make lock core expose, shell side has input string holes and exports string holes, enclosure is fixed with two parallel metal reeds, and metal spring leaf all respectively has hard contact, and two parallel metal reeds are connected to input and output respectively, the position of two parallel metal reeds is in the outer end points both sides of cursor, cursor isolating metal contact, when cursor forwards to away from hard contact, can connect these two metal spring leafs just; On base plate, four angles have fixing hole in order to fixing.

Above-mentioned said safety open shuts, and the lock core in its structure except enclosure is fixed with two parallel metal reeds, key, shell, base plate are all that high-strength insulation plastics are formed.

Superiority of the present invention: the principle of lockset utilizes on electrical appliance switch by the present invention, and the fail safe of electrical appliance switch is improved.

(4) accompanying drawing explanation

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

Accompanying drawing 2 is internal structure schematic diagram when a switch is on of the present invention;

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

Accompanying drawing 4 is the end view of lock core of the present invention;

Wherein: 1 is lock core, 2 is shells, and 3 is base plates, 4 is lock core bodies, and 5 is rotors, and 6 is lockholes, 7 is rotation axiss, and 8 is cursors, and 9 is lock core holes, 10 is input string holes, and 11 is export string holes, and 12 is fixing holes, 13 is metal spring leafs, and 14 is hard contacts, and 15 is inputs, 16 is outputs, and 17 is keys.

(5) embodiment

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

Above-mentioned said safety open shuts, and is fixed with the lock core 1 except two parallel metal reeds 13, key 17, shell 2, base plate 3 be all that high-strength insulation plastics are formed in its structure except shell 2 inside.

Using method of the present invention is: when mounted input line is connected on input 15 through input hole 10, output line is connected on output 16 through delivery outlet 11, when opening switch, key 17 is inserted lockhole 6 to rotate and cursor 8 is contacted with metal two contact 14 connected circuit, key 17 is not rotated that namely pull up to initial condition be closed switch by the used time.
