Description

The stealthy lock of a kind of magnetic

The utility model relates to the stealthy lock of a kind of magnetic, is a kind of stealth lock by no lockhole on the locking device of magnetic force control.

The lockhole that the insertion key is all arranged that door lock is general in existing technology, this is the stolen main cause of door.Existing magnetic anti-theft lock is a magnetic card, and the main land used of answering is the hotel, because magnetic and magnetic core on this magnetic card are worn easily, so bring a lot of troubles to the user, should not be generalized in the common resident family and use.Other has two kinds of more senior remote control lock and Fingerprint Lock, because high being difficult at present of cost popularized.

The purpose of this utility model is the design novel lockset that a kind of theftproof performance is strong, cost is low.

Scheme of the present utility model is as follows: comprise a door lock key 14 of being made up of two above magnetic patch 11 and shell 16, dead bolt 22, dead bolt connecting rod 31, dead bolt support 30, the dead bolt return spring 27 of door lock assembly, shell 16 is fixedlyed connected with dividing plate 4, the one side that it is characterized in that dividing plate 4 is the magnetic patch positioner, another side is that lock control devices is formed, and the magnetic patch positioner comprises rat bait shaft 3, clamp 5, pivoted frame 1, runner 2, rotating shaft 7, magnetic patch 8, pilot pin 9, location cave 10, locking face 12, return spring 13 more than two, lead rule 15 forms.Rat bait shaft 3 and dividing plate 4 are slidingly connected, and clamp 5 is fixedlyed connected with rat bait shaft 3, and pivoted frame 1 is fixedlyed connected with rat bait shaft 3, and pivoted frame 1 is positioned at the end of rat bait shaft 3, and runner 2 is housed at the two ends of pivoted frame 1 and pivoted frame 1 is rotationally connected.Two rotating shafts 7 are equipped with in the both sides of rat bait shaft 3 on the pivoted frame 1, are connected with pivoted frame 1 bearing by bearing 6.Magnetic patch 8 is fixedlyed connected with rotating shaft 7, and pilot pin 9 is fixedlyed connected with magnetic patch 8, and cave 10, location is arranged on the locking face 12, leads rule 15 and fixedlys connected with locking face 12.Runner 2 is positioned at leads on the rule 15.Return spring 13 1 ends are fixedlyed connected with rat bait shaft 3, and the other end is fixedlyed connected with locking face.Lock control devices comprises that knife-edge plectrum 24, an end and knife-edge plectrum 24 that projection 25 that the fish mouth clamp 18 that flexibly connect with rat bait shaft 3 are fixedlyed connected with dead bolt connecting rod 31 and dead bolt 22 are fixedlyed connected with the manual handle 29 of door fixedly connected the powerful spring 26 that the other end fixedlys connected with shell 16 and form.One end of knife-edge plectrum 24 is fixedlyed connected with the manual handle 29 of door, the breach of the other end and fish mouth clamp 18 contacts, there is a fulcrum 20 centre of fish mouth clamp 18, return spring 19 1 ends are fixedlyed connected the other end and fish mouth clamp 18 with shell 16 fixing, and the mid portion of knife-edge plectrum 24 and dead bolt connecting rod 31 join.The polarity arrangement of magnetic patch 11 its magnetic alignment in the door lock key 14 and the magnetic of the magnetic patch 8 in the magnetic patch positioner is opposite.

The utility model theftproof performance is good, cost is low.Because the used key and the spread geometry of the magnetic patch in the door lock can't be differentiated from the outside, used thief can't set about.If want to decode aligning method, because very many of the scheme of permutation and combination, so can't decode.It is a kind of new desirable family expenses door lock.

Below in conjunction with embodiment and accompanying drawing the utility model is illustrated:

Fig. 1-Fig. 3 is embodiment of the present utility model.

Fig. 1 be the magnetic patch positioner structure chart;

Fig. 2 is pivoted frame 1 and the vertical view of leading rule 16, magnetic patch 8;

Fig. 3 is the structure chart of lock control devices.

As shown in Figure 1, shell 16 is fixedlyed connected with dividing plate 4, one side dividing plate 4 is the magnetic patch positioner, another side is a lock control devices.Locking face 12 is fixedlyed connected with shell, and locking face 12 and key 14 contact.Rat bait shaft 3 and dividing plate 4 are slidingly connected in the magnetic patch positioner, and clamp 5 is fixedlyed connected with rat bait shaft, the position-limiting action of 5 rat bait shafts of clamp.Be fixed on that two ends have two runners 2 and pivoted frame 1 to be rotationally connected on the pivoted frame 1 of rat bait shaft 3 lower ends, the below of runner 2 is the tracks 15 with circular arc track, and track 15 has one section breach, and runner 2 and track 15 join, and can move along track 15.The inboard of runner has two rotating shafts 7 to be connected with pivoted frame 1 bearing by bearing 6, is fixed with magnetic patch 8 in the rotating shaft 7, and magnetic patch 8 is made up of S-N two parts, and pilot pin is fixedlyed connected with magnetic patch 8.Cave 10, location is arranged on the locking face 12, when in shell 16, rotating under the effect of the magnetic patch 11 of magnetic patch 8 in key 14 along the track of leading on the rule 15, when finding the position of choosing, pilot pin 9 falls in the cave 10, location, this moment, runner 2 also rotated on track 15, when pilot pin 9 fell into cave 11, location, runner 2 fell in the breach of track 15.Rat bait shaft 3 is released fish putting mouth clamp 18, fish mouth clamp 18 clockwise rotate at the effect lower edge of return spring 19 fulcrum 20, these macrura reevesii mouth clamp 18 discharge knife-edge plectrum 24, knife-edge plectrum 24 is rotated in the effect lower edge of powerful spring 26 axle 28 inhours, knife-edge plectrum 24 is connected with axle 28 hinges, and at this moment the projection 25 stirred on the dead bolt connecting rod 31 of knife-edge plectrum 24 makes dead bolt connecting rod 31 move along dead bolt support 30.Throw off the lock tongue slot 23 that is positioned on the door with the dead bolt 22 that dead bolt connecting rod 31 is fixed together, door is opened.Depress door handle 29 at closing time and fixedly connected with knife-edge plectrum 24, knife-edge plectrum 24 clockwise rotates at this moment, and knife-edge plectrum 24 falls in the breach of fish mouth clamp 18.Fish mouth clamp 18 have stipulated when design and can only inhour rotate that dead bolt 22 falls into again in the lock tongue slot 23 under the effect of return spring 27, and door is lockable.
