Abstract

The utility model belongs to the technical field of locksets, and particularly relates to a theft-proof door lock with a U-shaped panel. The utility model aims at the existing defects that the existing theft-proof door locks are not firm enough in the aspect of radial locking and can not axially lock door locks, and provides a theft-proof door lock which is firm in the aspect of radial locking and can axially lock door locks. The utility model comprises a U-shaped panel, an up-down sheet, a slip half shaft, a lock case, a back-resistant sheet, a trailing bar, a lock cover, a main tongue, a slip column, a lock tongue hook, a handle hole, a lock core hole and an inclined tongue, wherein the U-shaped panel is fixed with the lock case together. The main tongue is fixed on the trailing bar, and travels through a main tongue hole of the U-shaped panel. The up-down sheet is movably connected with the trailing bar. The lock tongue hook is hook-shaped. The hook part of the lock tongue hook travels through a tongue hook hole of the U-shaped panel. The slip column on the lock tongue hook respectively travels through a J-shaped slip slot on the up-down sheet, a J-shaped slip slot on the lock case and a J-shaped slip slot on the lock cover. The slip half shaft on the lock tongue hook travels through a straight slip slot on the lock cover.

Description

The safe-guard door lock of band U-shaped panel

Technical field

The novel lock technology field that belongs to of this use, particularly a kind of safe-guard door lock that uses on security door, the safety door that is applicable to.

Background technology

The dead bolt of existing safe-guard door lock all is to adopt the door latch type dead bolt, the panel of safe-guard door lock is plate shaped, owing to structural reason, the door latch type dead bolt is firm inadequately aspect locking radial, can not the opposite house lock shaft to locking, so the robber forces open the door from crack between a door and its frame and all can go smoothly easily, this makes the anti-theft feature of security door be greatly diminished.

Summary of the invention

The utility model is existing firm inadequately aspect the locking radial at existing safe-guard door lock, can not the opposite house lock shaft to the weak point that locks, provide a kind of not only firm aspect locking radial, and energy opposite house lock shaft is to the safe-guard door lock of the band U-shaped panel that locks.

The technical solution adopted in the utility model is finished in the following way: the safe-guard door lock of band U-shaped panel comprises U profile plate, world sheet, the slip semiaxis, lock box, retaining sheet, planker, locking closure, main tongue, slide post, the dead bolt hook, the handle hole, lock core hole, oblique tongue, wherein, U profile plate and lock box are fixed together, main tongue is fixed on the planker and passes the main tongue hole of U profile plate, world sheet and planker are slidingly connected, the dead bolt hook is hook-type, the hook portion of dead bolt hook is passed the tongue dog hole of U profile plate, slide post on the dead bolt hook passes the J-shaped sliding tray on the sheet of the world respectively, J-shaped sliding tray on the lock box and the J-shaped sliding tray on the locking closure, the slip semiaxis on the lock hook hook passes the straight sliding tray on the locking closure.When main dead bolt stretches out, planker drives world sheet and stretches out, at this moment the J-shaped sliding tray on the sheet of the world is stirred slide post, under the effect of J-shaped sliding tray on lock box, the locking closure and straight sliding tray, stretch out to level, after stretching out certain-length, because the straight sliding tray on the locking closure is to the position-limiting action of slip semiaxis, dead bolt hook level again stretches out, but slide post still can continue to slide in the J-shaped sliding tray on lock box, locking closure so world sheet forces the dead bolt hook to deflect, and the dead bolt hook has also been finished its dogging action when main tongue stretches out the main tongue hole on U profile plate both sides.When main dead bolt bounced back, planker drove world sheet retraction, and at this moment the J-shaped sliding tray of world sheet acts on the slide post on the dead bolt hook, produces deflection under the guiding of the J-shaped sliding tray on lock box, the locking closure, replys and colludes the card function.Level bounces back then.Thereby realize the switching of the safe-guard door lock of band tongue hook.

The safe-guard door lock of the utility model band U-shaped panel is compared with existing safe-guard door lock, and it is not only firm aspect locking radial to have, and energy opposite house lock shaft has improved the theftproof performance of security door greatly to the characteristics that lock.The utility model is particularly suitable as the door lock on all kinds of security doors.
