The utility model content
The utility model technical problem to be solved is the deficiency to above prior art, provide a kind of simple in structure, connect appliance switch lock reliable, good operating stability, this appliance switch lock can be controlled one, the break-make of two or more appliance circuits.
For addressing the above problem, the utility model provides a kind of appliance switch lock, comprises billiards lock structure, sensitive switch, is used to control the cam of sensitive switch break-make, and said cam is socketed on the lock core root of billiards lock structure.
End face one side of said cam is protruding; Between convex side and the relative recess side is transition arc; The action reed of convex side and sensitive switch place mounting plane protrude in the height of place mounting plane apart from d1 less than the action reed, the action reed place mounting plane of recess side and sensitive switch protrude in the height that belongs to mounting plane apart from d2 greater than the action reed.
Be socketed with the centring ring of axial limiting on the lock shell of said billiards lock structure, lock is established external screw thread on the shell and is combined with and billiards lock structure and centring ring are fixed to appliance switch lock the clamp nut on the installation panel.
Said lock core is provided with symmetrical pellet shot from a slingshot assembly A and pellet shot from a slingshot assembly B, and appended key forwards lock core to pellet shot from a slingshot assembly A or the arbitrary position of pellet shot from a slingshot assembly B can both be extracted, and need not to get back to former insertion position.
After adopting above structure, the utility model compared with prior art has the following advantages: the utility model appliance switch lock comprises billiards lock structure, cam, sensitive switch, and is relatively simple for structure.Cam is socketed on the lock core root of billiards lock structure; Cam can be controlled the break-make of sensitive switch; Sensitive switch is a prior art, and is sensitive, effectively be the characteristics of sensitive switch control circuit break-make, so this appliance switch lock connects reliable; Good operating stability, the break-make of control apparatus circuit effectively.In addition, as long as change the on-off function that just can realize one of control, two or more appliance circuits to the wiring of sensitive switch output.
Description of drawings
Shown in the drawings is the schematic cross-section of the utility model appliance switch lock.
Wherein: 1, billiards lock structure; 2, cam; 3, sensitive switch; 4, centring ring; 5, clamp nut; 11, lock core; 12, lock shell; 21, convex side; 22, recess side; 31, action reed.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to detail.
Shown in accompanying drawing, the utility model appliance switch lock comprises billiards lock structure 1, is used to control cam 2, the sensitive switch 3 of sensitive switch 3 break-makes, and cam 2 is socketed on lock core 11 roots of billiards lock structure 1.Billiards lock structure 1 is a prior art with sensitive switch 3, and billiards lock structure 1 comprises structures such as lock core 11, lock shell 12, spring, pellet shot from a slingshot, and sensitive switch 3 comprises structures such as action reed 31, moving contact, fixed contact, seldom introduces here.
End face one side of said cam 2 is protruding; Between convex side 21 and the relative recess side 22 is transition arc; The action reed 31 place mounting planes of convex side 21 and sensitive switch 3 protrude in the height of place mounting plane apart from d1 less than action reed 31, the action reed 31 place mounting planes of recess side 22 and sensitive switch 3 protrude in the height of place mounting plane greater than action reed 31 apart from d2.Cam 2 is socketed on lock core 11 roots of billiards lock structure 1, rotates with the rotation of billiards lock structure 1.It is the actuated element of sensitive switch 3 that the convex side of cam 2 does 21; When cam 2 rotates when convex side 22 turns to action reed 31 positions of sensitive switch 3; The reed 31 that will move is depressed; Action reed 31 is displaced to critical point and produces instantaneous operation, and action reed 31 terminal moving contact and fixed contacts are connected fast, thus the control apparatus circuit communication.
Be socketed with the centring ring 4 of axial limiting on the lock shell 12 of said billiards lock structure 1, lock is established external screw thread on the shell 12 and is combined with billiards lock structure 1 and centring ring 4 are fixed to the clamp nut 5 on the appliance switch lock installation panel.When this appliance switch lock is installed, billiards lock structure 1 is passed the preset holes of installation panel, overleaf centring ring 4 is socketed on the lock shell 12 and with installation panel then and is close to, then clamp nut 5 is tightened in the external screw thread on the lock shell 12.
The billiards lock structure 1 that present embodiment adopts; The rotational angle of its lock core 11 is 90o (promptly from left 45o to right 45o or from right 45o to left 45o); Lock core 11 cam 2 when left 45o is communicated with a circuit of sensitive switch 3 or breaks off, and cam 2 was communicated with or disconnection another circuit of sensitive switch 3 when lock core 11 was spent at right 45o.Lock core 11 rotates in left 45o ~ right 45o scope; Drive also rotation left 45o ~ right 45o scope in of cam 2: when lock core 11 also is that cam 2 is during at left 45o; The convex side 21 of cam 2 is positioned at the position of one of them action reed 31 of sensitive switch 3; The reed 31 that should move is depressed, and the circuit that the reed 31 that then should move is controlled is communicated with; When lock core 11 also is a cam 2 during at right 45o, the convex side 21 of cam 2 is positioned at the position of another action reed 31 of sensitive switch 3, and this another action reed 31 is depressed, and then circuit of these action reed 31 controls is communicated with or breaks off.Sensitive switch 3 both can have been controlled the break-make (circuit of will be a wherein any action reed 31 controls Connect Power device) of an appliance circuit, also can control the break-make (circuit of two action reed 31 controls connects an electrical equipment respectively) of two appliance circuits.The break-make of two appliance circuits of control as: the circuit of action reed 31 controls connects the electric fan circuit; The circuit of another action reed 31 controls connects air-condition circuits; When lock core 11 when left 45o (right 45o); The electric fan pass of turning on the aircondition, and lock core 11 is when right 45o (left 45o), air-conditioning is opened electric fan and is closed.
Certainly, this appliance switch lock also can be controlled the break-make of a plurality of appliance circuits, as long as change sensitive switch into the sensitive switches that join, corresponding place is done and cooperated the changes that join sensitive switch to get final product more, seldom does repetition here more.
Above embodiment be to the explanation of the utility model with explain that further rather than to the restriction of the utility model, any modification of in the interest field of the utility model, being done all falls into the protection range of the utility model.
