Embodiment Construction

[0071] Figures 1 to 1 8 shows a novel door lock system according to an exemplary embodiment of the present invention, which mainly includes a keycard detection device 1500 , an unlatching mechanism 1700 and a latch device 1970 . It will be described in detail below.

[0072] The key card detection device 1500 is made up of a certain number (adjustable according to different needs) of the tumbler assembly 1400, a support plate 1530, a combination disk 1540 and a spring 1550, see figure 2 shown. All the above components are connected in series by the rod 1570 and the central shaft 1560, and are located between the lower fixing plate 1510 and the upper fixing plate 1520 together with a support 1610, and can move between a first position and a second position.

[0073] exist image 3 Among them, a set of tumbler pins 1430 are laterally located in the slots 1424, 1414 of the upper and lower tumbler members 1420, 1410, and the raised portion 1431 in a specific position in each ...

Abstract

The key card detecting device includes several pairs of bolt assembly and cipher disc. Each bolt assembly has several bolt pins to respond to the insertion of the key card to reciprocate, and each bolt pin has matched part set in special position. Each cipher disc has several second cipher parts arranged in specific assembling mode, and may be rotated independently for selecting cipher combinations in different positions. When the first cipher part in the inserted key card coincides completely with the second cipher part of the cipher disc in the selected position, all the bolt pin matching parts will align to the second cipher part in the cipher disc and the key card detecting device can move integrally from the first position to the second position. Or else, the key card detecting device will be limited in motion. The present invention also relates to one door lock system with the key card detecting device, and has the advantages of easy altering of cipher, simple structure, convenient use, etc.

Description

technical field [0001] The invention relates to a key card detection device, in particular to a key card detection device which can conveniently change passwords without dismantling each component and is easy to memorize. The present invention also relates to a password card type door lock system using the key card detection device. Background technique [0002] Typically, most mechanical locking systems employ metal key and tumbler assemblies that are not capable of resetting. When keys are lost or due to security concerns, it is often necessary to replace a new locking system or call a locksmith for help. Therefore, password card type locking systems have been more and more widely used, some of which also provide the function of resetting passwords. In these password card type locking systems, it is usually necessary to use a key card detection device to detect whether the inserted key card matches the preset password, so as to start or switch its working state according...
