Detailed Description
The present invention will be further described with reference to the accompanying drawings, and the structure and principle of the present invention will be clear to those skilled in the art. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 and 2, the utility model relates to a take spring mechanical lock of contact switch, the concrete structure is as follows:
including lock shell, lock core, spring bolt and spring, be equipped with L shape cavity in the lock shell, lock core and spring bolt are at the cavity fit, and lock shell cavity inner wall is connected to spring one end, and the spring bolt is connected to the spring other end, and a recess has been seted up to the spring bolt lower part, and recess one side is equipped with the stair structure that a breach formed, and the lock core top is equipped with arc lug and spring bolt cooperation. The lock core is arranged in the lock shell through the lock sleeve, a notch is further formed in the lock core, and the spring ball screw is arranged on the lock shell and used for being matched with the notch in the lock core. The lock shell is also provided with a bolt positioning screw and a lock core positioning screw.
Refer to fig. 3, do the spring mechanical lock assembly schematic diagram at initial position, initial position is called 0 bit, when 0 bit, lock core top arc lug sets up in the spring bolt recess, and arc lug does not have spacingly to the spring bolt, and the key can be extracted. The lock at the moment is the same as a common spring lock, the spring bolt can retract under the action of external force, and when the external force is absent, the spring bolt can automatically rebound under the action of the spring, so that the aim of locking is fulfilled. But this state is not theft proof.
Referring to fig. 4 and 5, the mechanical spring lock of the present invention rotates clockwise 90 ° at 0 position, and in this state, the mechanical spring lock is a spring lock, and the key cannot be pulled out. The lock core can drive the spring bolt retraction at rotatory in-process, and the spring bolt retraction stroke reaches the maximum value this moment, and spring ball tacking screw pops out and corresponds the recess cooperation on the position with the lock core, and the spring bolt can be fixed in this position of 90, and the key is being turned round always to the hand, facilitates the use, and anticlockwise wrench movement under this state gently, alright resilience, it is very nimble.
Referring to fig. 6 and 7, spring mechanical lock be at 0 position anticlockwise rotation 180, be the mechanical lock state this moment, at this moment, lock core top arc lug is rotatory to spring bolt rear portion one end from spring bolt recess opposite side, spacing to the spring bolt, during this state, the key can be extracted. In this motion process, because lock core and spring bolt contactless, can wrench movement very smoothly to 180 positions, to this position lock core can contact with the spring bolt, the spring bolt is under the effect of spring bolt set screw, can not outwards move, same anticlockwise rotation is when 180, spring ball tacking screw pops out the recess cooperation on corresponding the position with the lock core, can make a sound, simultaneously, there is a vibrations sense on hand, so anticlockwise rotation is to 180 degrees, just reach the ultimate value, the spring lock switches into the mechanical lock function this moment, the spring bolt can not retract, reach the purpose of theftproof, simultaneously, lug on the lock core is pressed the button of contact switch, the power is opened, can remind the user to lock the battery case well.
