Detailed Description
The present invention is further described below in conjunction with the following drawings, the structure and principle of which will be apparent 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 invention relates to a spring mechanical lock with a contact switch, which has the following specific structure:
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.
Referring to fig. 3, the assembly diagram of the spring mechanical lock in the initial position is shown, the initial position is referred to as 0 position, and at 0 position, the arc-shaped projection at the top of the lock core is arranged in the lock tongue groove, and the arc-shaped projection does not limit the lock tongue, so that the key can be pulled out. 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 is rotated clockwise by 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, the mechanical spring lock of the present invention rotates 180 ° counterclockwise at 0 position, and at this time, the mechanical lock is in a mechanical lock state, and at this time, the arc-shaped projection at the top of the lock cylinder rotates from the other side of the lock tongue groove to one end of the rear portion of the lock tongue to limit the lock tongue, and in this state, the key can be pulled out. 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.
