Abstract

The utility model relates to an anti-prizing door lock. A cylindrical tongue rotary body (26) and a fork rotary body (27) are arranged in the lock, wherein, the fork rotary body (27) is provided with a handle (1) and a sliding slot (2) and a window (3) are arranged on a fork rotary body casing (4); displacement generated by the handle (1) which slides up and down in the sliding slot (2) causes a lock fork of the fork rotary body (27) and a lock tongue of the tongue rotary body (26) to lie in a vertical or horizontal transverse state. When two rotary bodies are rotated for 90 DEG C, different positions formed by the lock tongue and the window of the casing lock or unlock the door. The lock arranged by fixing bolts from indoor and is locked and unlocked in a rotary way under the protection of the casing so that the lock is not easy to prize up and has the advantages of simple structure, low cost and easy operation.

Description

The pick-proof door lock
The utility model relates to a kind of door lock.
Usually the door lock of usefulness is to be made of lock body, lock core, parallel mobile dead bolt.Though switch is easy, very easily to pry open, the door lock that has need only just can be pried open door easily with material (as Steel Ruler) hard slightly, that approach any, and especially storehouse, dwelling house etc. are located, and the door lock theftproof is poor, and is dangerous.
But the utility model provides a kind of safety good pick-proof door lock.For achieving the above object, the pick-proof door lock be the lock in be equipped with cylindric fork turn and tongue turn.Fork is turned handle is housed, and shell has window and chute.Tongue is turned and is drilled with the hole, slide bar can slip into or skid off in the hole that tongue is turned in the active force head portion of spring, utilize the rotation that drives that fork is turned and tongue is turned of sliding up and down of handle, fork is turned and tongue is turned and can be in vertical state or horizontal accumbency state, turn rotation 90 ℃ the time when two, and the diverse location that dead bolt and shell window form with door lock firmly or open.The pick-proof door lock is installed with set bolt in door, and under the protection of shell, the rotation mode switch makes lock be difficult for prying open, simple and reasonable for structure, safety, and switch is easy, and is cheap.
Earlier partition (13) will be fixed in the circular hole together with the lock nuclear (8) of lock core (7) with two pieces of screws (15) when installing and using, jump ring (18) is fixed on plectrum (14) on the lock core (7).Slide bar (22) is contained on the back shroud (16) of two guiding trestles, back shroud (16) is to be fixed on the turn E face of shell (5) of tongue by screw (28), plate washer (17) is fixed on the slide bar (22) with pin (24), the afterbody of slide bar (22) is equipped with spacing jump ring (21), under spring (23) active force, the head of slide bar (22) can slip into tongue turn hole (29) or (30) on (26).Jump ring (25) can prevent tongue turn (26) from tongue is turned shell (5), skid off.Bolt (9) fixes on locking on the door-plate (12).When handle (1) is in the upper limit position of chute (2), the head of slide bar (22) is in hole (29), the tongue lock fork that dead bolt and fork in (26) turn in (27) of turning is in vertical state, fork is turned (27) with window (3) shelves firmly, tongue turn (26) can not from window (3), level shift out, at this moment, door is lockable.
Insert key (19) in keyhole (6), reverse key (19) clockwise, plectrum (14) is with lock core (7) rotation, and plectrum (14) is stirred baffle plate (17), baffle plate (17) overcomes the active force of spring (23) together with slide bar (22), and the head of slide bar (22) is skidded off from hole (29).Move the lower position of handle (1) to chute (2), key (19) revolution back is taken out, at this moment, the fork turn (27) under the effect of handle (1) together with tongue turn (26) rotate 90 ℃ of angles jointly, under the effect of spring (23), the head of slide bar (22) slips in the hole (30), fork the turn dead bolt of (26) of lock fork and the tongue of (27) of turning is in horizontal accumbency state, the turn dead bolt of (26) of tongue aligns with window (3), and dead bolt level from window (3) shifts out, and door is opened.Again insert key (19) in keyhole (6), reverse key (19) clockwise, plectrum (14) is stirred baffle plate (17), and plate washer (17) overcomes the active force of spring (23) together with slide bar (22), and (30) skid off from the hole to make the head of slide bar (22).Move the upper limit position of handle (1) to chute (2), key (19) revolution back is taken out, door is lockable.
