The utility model discloses simple structure, convenient to use, low cost and theftproof nature are good, are fit for vast ordinary consumer and use.

Description

The anti-theft lock device

Technical field

The utility model relates to a kind of lock, particularly a kind of anti-theft lock and be used for the key of this anti-theft lock.

Background technology

Lock is an apparatus very general during people live, and its main purpose is to prevent the harm of undesirable to people, gives daily life daily life and goes out to play the safety guarantee effect.But the mechanical lock of Xiao Shouing is simple in structure mostly in the market, and it mainly is made up of spring, hoodle and trivial cover, and this lock is opened by simple unlocking tool easily, thereby causes problem such as economic loss.

The utility model content

The purpose of this utility model is to solve the low problem of theftproof of existing machinery lockset, provides a kind of theftproof performance high anti-theft lock device.

The technical solution of the utility model is achieved in that a kind of anti-theft lock device comprises, lock core, theft protection plate and theft protection plate catch bar.Lock core is divided into lock core 1 and lock core 2 places the theft protection plate two ends respectively.Theft protection plate form by two iron plates and two iron plates mutually at an angle of 90, the theft protection plate one side promotes involvement by theft protection plate and receives trivial putting, theft protection plate thickness, width just with lock core keyhole thickness, the width unanimity, and it is parallel with the inward flange of lock core 1 respectively, parallel with the keyhole of lock core 2 and just with its hole plug, when key inserts first section lock core 1, just with the spring of lock core 1, the pellet shot from a slingshot assembly is right, get final product half-twist, the while theft protection plate also is rotated 90 ° of theft protection plates that will stop up lock core 2 and pushes open vertical with its outward flange, key just enters in second section lock core 2, and it is right in circular keyhole and the lock core 2 the spring marble assembly to be set, and rotates to be about to the lock unlatching.Its front end of key that wherein is used for this anti-theft lock device is the waveform sawtooth, and three circular apertures are arranged below sawtooth.

The utility model has solved the problem that mechanical lock is in the past opened easily by simple tools easily, and a kind of anti-theft lock device simple in structure, with low cost, easy to use is provided.

The specific embodiment

Described in detail below with reference to accompanying drawing:

As shown in Figure 1, a kind of anti-theft lock device comprises, lock core, theft protection plate and theft protection plate catch bar.Lock core is divided into lock core 1 and lock core 2 places the theft protection plate two ends respectively.Theft protection plate form by two iron plates and two iron plates mutually at an angle of 90, the theft protection plate one side promotes involvement by theft protection plate and connects, theft protection plate thickness, width just with lock core keyhole thickness, the width unanimity, and it is parallel with the inward flange of lock core 1 respectively, parallel with the keyhole of lock core 2 just with its hole plug, when key inserts first section lock core 1, just with the spring of lock core 1, the pellet shot from a slingshot assembly is right, get final product half-twist, the while theft protection plate also is rotated 90 ° of theft protection plates that will stop up lock core 2 and pushes open vertical with its outward flange, key just enters in second section lock core 2, and it is right in circular keyhole and the lock core 2 the spring marble assembly to be set, and rotates to be about to the lock unlatching.The theft protection plate catch bar is made up of iron and extension spring as shown in Figure 1.

As shown in Figure 2: be used for this anti-theft lock key its form by waveform sawtooth and small sircle hole, front end at key is formed for opening lock core 1 and is promoted theft protection plate 3 half-twists by the waveform sawtooth, key just enters in the lock core 2 smoothly, and this moment, the circular aperture of waveform sawtooth below just can be opened lock with spring, pellet shot from a slingshot pairing rotation.

Claims (2)

1, a kind of anti-theft lock device, comprise lock core (1), (2), theft protection plate (3), theft protection plate catch bar (4), it is characterized in that: theft protection plate (3) is connected the right-hand member of trivial cover (5) by theft protection plate catch bar (4), and place between lock core (1), (2), lock core (1), (2) are separately fixed at the rear and front end of trivial putting (5).

2, a kind of anti-theft lock device according to claim 1, it is characterized in that described theft protection plate (3) is mutually 90 ° of iron plates by two and forms, wherein a slice is parallel with lock core (1) inward flange, and another sheet is parallel with the keyhole (6) of lock core (2), and its thickness is consistent with keyhole (6).
