Abstract

The utility model belongs to a lock which relates to a magnetic card lock, comprising a magnetic card lockset. The utility model is characterized in that a cryptographic card is inserted on the lockset of the door. The code surface of the cryptographic card corresponds to the code surface of a magnetic card key which is inserted from the outside of the door, and is parallel to the code surface of the magnetic card. Thereby, the cryptographic card is easy to change and take, and is not easy to steal by other people and change to open the magnetic card lock. When the magnetic card key is lost or taken by the guest, the cryptographic card is changed without changing the lockset, which is convenient, timesaving, laborsaving and economical. The utilization rate of the guest room can be increased, and the operating cost can be reduced for the hotel. The utility model is an ideal replacing product.

Description

Magnetic card lock

The utility model belongs to lockset, relates to a kind of magnetic card lock.

The encrypted card of existing magnetic card lock is all established on the lockset that is contained in outdoors, as easy-offtaking, easily is stolen, and is easily changed by other people and will lock unlatching easily; So encrypted card all is enclosed on the lockset of outer side of door, be difficult to take out.After magnetic card key is lost or is taken away by the guest, can only change lockset, unusual trouble, effort but also time-consuming not only, expense is very high again, and especially waste is very big; With regard to the hotel, can't recover immediately to use because of the guest room, influence its utilization rate, operating cost improves, and economic benefit reduces.

The purpose of this utility model provides a kind of encrypted card and picks and places easily, is difficult for being stolen not only but also be difficult for being changed by other people and will locking the magnetic card lock of opening.

The purpose of this utility model is to realize by encrypted card being established on the lockset that is contained in the door, is about to realize on the lockset that encrypted card is inserted into an inboard; So encrypted card is got and changed easily, be difficult for again being stolen and changing and will lock unlatching by other people.After magnetic card key is lost or is taken away by the guest, need not to change lockset, as long as change encrypted card, enable new magnetic card key and get final product, not only convenient but also laborsaving saving time, economical again; With regard to the hotel, the guest room can recover to use at once, improves the utilization rate in guest room, reduces operating cost, increases economic efficiency.

A kind of magnetic card lock comprises the magnetic card lockset, it is characterized in that: encrypted card is established on the lockset that is contained in the door, and its password face is with from the password face of the magnetic card key that inserts outdoors relatively and parallel.Obviously, the password face of encrypted card is can the same level face parallel, vertical or become angle ground to be inserted on the interior lockset of door.The password face is meant the face that is provided with password.

Describe in detail below in conjunction with embodiment and accompanying drawing thereof:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the right view of Fig. 1;

Fig. 3 is a kind of rack gear of the present utility model.

It among the figure a kind of ball-type magnetic card lock.Wherein: (1) encrypted card lock pin; (2) encrypted card; (3) curved bar; (4) slide plate; (5) cylinder plate; (6) opening safety button; (7) traditional ball lock; (8) magnetic card key; (9) contain the spacing push rod of buffer spring; (10) pintle hook lock driving lever; (11) pintle hook lock; (12) driven gear; (13) driving gear; (14) main tooth bar; (15) driven tooth bar.

Encrypted card among the figure (2) is inserted on the lockset from the back side of magnetic card key socket, promptly is inserted on the lockset in the door; And the positioning recess and encrypted card lock pin (1) location that utilize encrypted card (2) edge to be provided with; The password face same level face of the encrypted card behind the location (2) is vertical, and parallel and relatively with the password face of the magnetic card key (8) that inserts from lockset outdoors.In the time will changing encrypted card (2), as long as unclamp encrypted card lock pin (1), encrypted card (2) just can be extracted out from the encrypted card socket that is arranged on the inboard lockset; Inserting new encrypted card (2) and fastening encrypted card lock pin (1) subsequently gets final product.Not only time saving and energy saving but also very convenient.Establish the gland that is contained on the encrypted card socket and substitute encrypted card lock pin (1) and positioning recess for encrypted card (2) can being picked and placeed more easily, can adopting.

Ball-type magnetic card lock among the figure is to adopt traditional ball lock (7) to assemble; The magnetic card lock core must be arranged on dead bolt position at regular intervals.Magnetic card key socket among the figure just is arranged on pintle hook lock (11) outer compound plate at regular intervals, and encrypted card (2) is inserted on the corresponding position from the back side of magnetic card key socket.Between cylinder plate (5) and pintle hook lock (11), must be provided with transmission mechanism.Transmission mechanism among Fig. 1 and Fig. 2 is the curved bar transmission mechanism, successively by curved bar (3), slide plate (4), the spacing push rod (9) that contains buffer spring and pintle hook lock driving lever formations such as (10) with cylinder plate (5) motion.After magnetic card key (8) inserted from the magnetic card key socket, as long as the password on the same encrypted card of password (2) in the magnetic card key (8) is corresponding one by one, magnetic card key (8) just can continue to advance inward, and cylinder plate (5) is promoted; Be connected and rotate around the axle that is located on the crooked position with the curved bar (3) of cylinder plate (5) motion once the same cylinder plate (5) of cranking arm, another is just cranked arm and to push slide plate (4) is downward; The spacing push rod (9) that contains buffer spring is along with slide plate (4) moves downward on the position that is pushed to qualification, just in time make pintle hook lock driving lever (10) with pintle hook lock (11) dislocation on the position of opening, lock promptly is in opening.After being pushed on the position that limits when spacing pre-bar (9) with regard to transfixion, the slide plate (4) of this moment is if also can only compress buffer spring in the continuation motion, and promptly the super distance displacement of slide plate (4) is to compensate by the buffer spring that contains on the spacing push rod (9).Fig. 3 is a kind of rack gear, is made of main tooth bar (14), driving gear (13), driven gear (12), driven tooth bar (15), the spacing push rod (9) that contains buffer spring and pintle hook lock driving lever (10) with cylinder plate (5) motion successively.When cylinder plate (5) is mobile, drive main tooth bar (14) parallel motion, main tooth bar (14) moves downward driven tooth bar (15) by driving gear (13) and driven gear (12), and the spacing push rod (9) that will contain buffer spring is pushed on the position that limits, and makes lock be in opening.After magnetic card key (8) was extracted out, transmission mechanism automatically reset, and made lock be returned to lock-out state.

For making magnetic card lock also can be in opening without magnetic card key (8), so that indoor have the frequent turnover of man-hour and can shut the door, also be provided with opening safety button (6) on the lockset of the door inboard of the magnetic card lock among the figure, can make lock be in the insurance knob of opening; This opening safety button (6) acts on the spacing push rod (9), and when rotarily opening stop button (6), opening safety button (6) can be passed spacing push rod (9) on the position that limits and make lock be in opening; Counter-rotating promptly resets, and lock is promptly replied in lock-out state.

Obviously, the utility model can not only repack the ball-type magnetic card lock into traditional ball lock (7), can also repack other conventional lock that contain inside and outside handle into corresponding magnetic card lockset.
