[0023] The specific implementation of the utility model will be described in further detail in combination with the drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model.
[0024] Please refer to Figures 1-4The utility model provides a novel anti -impact vibration door lock structure, including lock shell 1, the lock shell 1 includes the lock tongue 10 of rotation setting in the lock shell 1, the first opening 11 of setting in the side of lock shell 1, the first torsional spring 12 of using with the lock tongue 10 cooperation and the second opening 13 of setting on the lock shell 1, the lock tongue 10 can from the first opening 11 extend or retract;
[0025] It further comprises a bracket 2 fixedly arranged in the inner cavity of the lock shell 1.
[0026] The electric locking device 3 comprises an electromagnet 30 fixedly arranged on the bracket 2, a lock piece 31 movably arranged on the bracket 2, and a return spring 32 having two ends connected to the lock piece 31 and the bracket 2 respectively, the lock piece 31 and the bracket 2 form a seesaw structure, one end of the lock piece 31 extends above the electromagnet 30 and is used in cooperation with the electromagnet 30, and the other end is used for locking or unlocking the lock tongue 10.
[0027] In the above structure, the bracket and the lock piece form a seesaw structure, and one return spring is connected to the lock piece on one side of the lock tongue and the bracket, so as to ensure that the lock piece on one side of the lock tongue is subjected to a downward force exerted by the return spring in a normal state, thereby enabling the lock piece to lock the lock tongue, when a user needs to open the door lock, the electromagnet is started, the lock piece on one side of the electromagnet is subjected to magnetic force attraction and thus moves downward, the lock piece on one side of the lock tongue moves upward through the seesaw structure, thereby enabling the lock tongue to be unlocked, and the return spring is subjected to an upward force exerted by the lock piece on one side of the lock tongue and thus deforms; when the user needs to lock the door lock, the electromagnet is turned off, the return spring recovers from deformation and drives the lock piece on one side of the lock tongue to re-lock the lock tongue downward, and the overall seesaw structure of the bracket and the lock piece increases the stability and shockproof effect of the door lock.
[0028] Specifically, a manual unlocking device 4 is movably arranged on the side of the lock shell 1, the manual unlocking device 4 comprises a pressing rod 40 penetrating through the second opening 13 and a second torsional spring 41 fixedly arranged at one end of the pressing rod 40, the lock shell 1 is provided with a first limiting protrusion 14 used in cooperation with the second torsional spring 41, and the end portion of the second torsional spring 41 is bent and extends above the lock piece 31, so that the manual unlocking device can be manually unlocked when the electromagnet is powered off or cannot be started.
[0029] Specifically, the one end of the pressing rod 40 is bent and extended to form a pressing portion 400, so that the user has a force exertion platform when needing to press the pressing rod, thereby reducing the force required by the user.
[0030] Specifically, the pressing rod 40 is provided with two limiting grooves 401, and the lock shell 1 is provided with limiting blocks 15 matched with the limiting grooves 401, the cooperation of the two limiting grooves and the two limiting blocks can limit the position of the pressing rod and prevent the displacement of the pressing rod, and can also guide the pressing rod.
