Description

Anti-theft door lock

Technical field

The present invention relates to lock technology field, more particularly to a kind of Anti-theft door lock.

Background technology

At present, occur all kinds of form door locks on the market；Mechanical lock class divides A, B, C to tie according to technology opening time and difficulty Configuration formula has a lock cylinder and the class of blade lock core two, and lock cylinder is divided into single pearl, double-row bead, yi word pattern and cross etc. again. Intelligent electronic lock class have induction door lock, fingerprint gate lock, cipher door lock, antitheft door swipe the card lock, recognition of face lock etc..Using electronics skill Art realizes and opened that the key of electronic lock is easy to carry, and unlocking mode is more more using electronic switch principle driving calutron Sample.Existing electronic lock can only carry out locking antitheft door by dead bolt mostly, and impact resistance, security do not have much room for improvement.

The disclosure of background above technology contents is only used for design and the technical scheme that auxiliary understands the present invention, and it is not necessarily Belong to the prior art of present patent application, no tangible proof show the above present patent application the applying date In the case of disclosed, above-mentioned background technology should not be taken to evaluate the novelty and creativeness of the application.

The content of the invention

Present invention aims at propose it is a kind of equipped with dead bolt basis adding a lock ring, to improve locking for door lock Security.

Preferably, the present invention can also have following technical characteristic：

Anti-theft door lock, the safe-guard door lock include shell, lock frame, dead bolt, motor, driving member, upper connecting rod, drop-down Bar, the dead bolt, motor, driving member, upper connecting rod, lower pull bar are assemblied on the lock frame, lock frame described in the shell seal, Also include lock ring, the lock ring has opening, and its lower end is flexibly connected with the lock frame, and upper end is flexibly connected with upper connecting rod；It is described Lock ring bottom is that knee top is straight-bar；The knee is connected with the straight-bar axis hole；The lock ring by with it is described lock frame, on Pull bar is combined into a linkage.

Further, the lock ring knee body of rod is in a variety of gradients.

Further, in addition to the first bearing pin, the second bearing pin, the 3rd bearing pin, the lock ring lower end are sold by described first Axle is rotatably connected with the lock frame；The knee and straight-bar of the lock ring are rotatably connected by second bearing pin；The lock Ring upper end is rotatably connected by the 3rd bearing pin with the upper connecting rod.

Further, first bearing pin, the second bearing pin, the 3rd bearing pin be arranged in parallel.

Further, in addition to some guiding slide plates, the guiding slide plate is incorporated on the lock frame, and is distributed in described Upper connecting rod, lower pull bar both sides.

Further, the extended lock frame 20-35mm of the lock ring.

Further, the lock ring stretches out in two stages, and its first stage stretches out 20mm, and second stage stretches out 35mm.

Further, the lock ring is hard metal material.

The beneficial effect that the present invention is compared with the prior art includes：Knee is designed to down narrow wide structure, can effectively save The about space-consuming of knee；Knee, straight-bar, lock frame, upper connecting rod are combined into one group of linkage by way of axis hole connection, if Count ingenious, flexibility height；Lock ring according to service condition, by its distance that controller stretches out on request, can improve the safety of door lock Performance.

Brief description of the drawings

Fig. 1 is schematic structural view of the invention；

Fig. 2 is present invention assembling schematic cross-section.

Embodiment

With reference to embodiment and compare accompanying drawing the present invention is described in further detail.It is emphasized that What the description below was merely exemplary, the scope being not intended to be limiting of the invention and its application.

With reference to the following drawings, non-limiting and nonexcludability embodiment will be described, wherein identical reference represents Identical part, unless stated otherwise.

Anti-theft door lock as shown in Figure 1, the safe-guard door lock 7 include shell, lock frame 5, dead bolt 3, motor 1, biography Moving part 2, upper connecting rod 6, lower pull bar 4, the dead bolt 3, motor 1, driving member 2, upper connecting rod 6, lower pull bar 4 are assemblied on lock frame 5, The shell is set on lock frame 5, and the lock ring has opening, and its lower end is flexibly connected with the lock frame 5, upper end and upper connecting rod 6 It is flexibly connected, the lock ring is stainless steel.The lock ring bottom is that knee 9-1 tops are straight-bars 9, the knee 9-1 and Straight-bar 9 is rotatably connected by second bearing pin；The lock ring lower end is that knee 9-1 lower ends are rotatable by the first bearing pin It is incorporated on lock frame 5；The lock ring upper end is that the right-hand member of straight-bar 9 is rotatably incorporated on upper connecting rod 6 by the 3rd bearing pin.Lock The ring knee 9-1 bodies of rod are in a variety of gradients, knee 9-1 narrow wide structures under being in, can effectively save knee 9-1 space-consuming.It is curved Bar 9-1, straight-bar 9, lock frame 5, upper connecting rod 6 are combined into one group of linkage by way of axis hole connection, and flexibility is high.

In order to obtain more preferable effect, first bearing pin, the second bearing pin, the 3rd bearing pin are be arranged in parallel, it is whole to increase The harmony of individual bar linkage structure.The extension elongation of lock ring and dead bolt 3 is controlled by electronic lock power supply size, lock ring and dead bolt 3 exist Extended 20mm and 35mm is distinguished in the case of by different voltages.
