Antitheft lock

Abstract

The invention discloses an antitheft lock and relates to the technical field of antitheft products. The antitheft lock comprises a lock body, a main lock tongue, an oblique lock tongue, an outer handle and an inner handle. The lower end of the main lock tongue is provided with a main lock tongue linkage column connected with a main lock tongue pushing sheet. The main lock tongue pushing sheet is provided with an oblique groove matched with the main lock tongue linkage column. The main lock tongue is further provided with a transverse long kidney-shaped hole matched with a pushing sheet positioning column on the lock body. The oblique lock tongue is fixed to the top of a telescopic rod. The outer handle and the inner handle are connected with a lock tongue execution assembly. The outer handle and the inner handle drive the main lock tongue pushing sheet to move leftwards and right wards and drive the telescopic rod to move up and down through the lock tongue execution assembly. The outer handle and the inner handle drive the main lock tongue and the oblique lock tongue to stretch out and retract easily through the lock tongue execution assembly, the requirement for one-way opening and closing of balcony doors, bathroom doors, corridor doors, fire exit doors and the like can be met, or the requirement of special occasions which are normally opened and temporarily closed is met. The antitheft lock has the advantages of being simple and compact in structure and convenient to operate, specification standardization can be achieved, the interchangeability is improved, and large-scale application and popularization are facilitated.

The electronicization of interior door locks and the electronicization of door locks in some specific places has just begun. However, electronic locks must be equipped with emergency unlocking devices according to the national industry standard GA701-2007. At present, most anti-theft locks on the market still use spare keys. Emergency unlocking results in no difference in safety performance between electronic locks and mechanical locks, and the price is still high, which cannot stimulate users' desire to use. The reason is that the innovative technology is weak, and the product does not break through the smart needs of users, so the essential difference is not big; Simultaneously the structure of existing anti-theft lock is loaded down with trivial details, and manufacturing cost is higher
