Abstract

The utility model relates to a hanging-in type bull-nose lock which is suitable for locking a double door and comprises a lock casing, a turntable, a blocking nail and a link mechanism which is composed of a lock rod, a pawl, a transverse rod, a lock head and a spring. The utility model adopts the form that a lock head is hung inversely, and the lock is matched with a hook type lock frame corresponding to the lock head, and a double door is directly locked. The problems that the double door only can be locked by ordinary padlocks and the traditional bull-nose locks can not directly and conveniently lock the double door are solved. The utility model has the advantages of simple structure, low cost, convenient use and high practicability, and is an ideal padlock for double doors.

Description

Hang the formula cattle head lock

The utility model relates to hangs the formula cattle head lock, is particularly useful for directly locking double door.

At present, known cattle head lock can only be used to lock single door, and its structure all is that tapered end inserts in the tapered end cartridge of installing on the doorframe, and tapered end directly connects locking bar, and the compression spring is housed on the locking bar, when opening the door, rotates Unlocking knob and makes locking bar be pressed into lock housing together with tapered end.When locking a door, as long as unclamp Unlocking knob, just locking bar bounces back into original position together with tapered end under the spring force effect.For the two fan Men Eryan that split, because the both sides of two fan doors can both be rotated, if wherein Yishanmen fix, tapered end will be released along with the rotation of door-plate, do not have the effect of lock, and the deficiency of existing this cattle head lock maximum is exactly to pin double door in direct convenience ground.

The purpose of this utility model provides a kind of simple in structure, can directly lock the extension of double door and go into the formula cattle head lock.

The utility model is hung into the formula cattle head lock, it comprises lock housing, rotating disk, retaining nail and by locking bar, ratchet, transverse bar, tapered end, the link gear that spring is formed, described tapered end reversal of the natural order of things is fixed on the spring hanging plate, spring hanging plate and two locking bars link, and spring hanging plate and tapered end mated position place are provided with the lock frame; Lock housing is provided with the spring catch nail.Described lock frame section becomes hook-shaped, and the hook groove is fixed on tapered end on the spring hanging plate with reversal of the natural order of things and is affiliated to and is hooked in.Be provided with spring stop between described two locking bars, spring stop is fixed by screw hole column.

The utility model is hung into the formula cattle head lock, be best suited for the lock double door, adopt the form of reversal of the natural order of things tapered end, join and corresponding coupling type lock frame with it, directly double door is pinned, having solved double door can only be with the history of common padlock, has solved the problem of the lock double door that traditional cattle head lock can not direct convenience simultaneously.It is simple in structure, and is cheap, easy to use, is the desirable padlock of double door, has practicality widely.

Description of drawings:

Fig. 1 is a structural front view of the present utility model.

Fig. 2 is a structure vertical view of the present utility model.

Fig. 3 is a structure graph of the present utility model.

Below in conjunction with accompanying drawing an embodiment of the present utility model is further described:

The utility model is hung into the formula cattle head lock, and it is mainly by lock housing 5, and tapered end 11 is locked frame 9 and is located at lock housing 5 interior link gears and forms, and link gear is made up of rotating disk 1, locking bar 3, transverse bar 6, ratchet 4, compression spring 12.Tapered end 11 reversals of the natural order of things are fixed on the spring hanging plate 14, and the other end of spring hanging plate 14 is fixedly connected by spring stop 10 and two locking bars 3 and is one, and locking bar 3 links to each other with Unlocking knob simultaneously.Be provided with spring stop 13 between two locking bars 3, spring stop 13 is fixing by screw hole column 15.The fixing tapered end 11 relative position places of reversal of the natural order of things are provided with lock frame 9, and the fixing tapered end 11 of lock frame 9 sections and reversal of the natural order of things is affiliated to and is lock-out state, and is shown in Figure 2.Lock housing 5 is provided with spring catch nail 8, and spring catch nail 8 usefulness small balls and spring 17 are fixing, and retaining is followed closely 2 and is located at ratchet 4 horizontal position that turns clockwise.When opening the door when the rotation Unlocking knob or with key insertion rotating disk 1, stir transverse bar 6 and promote locking bars 3 under the effect of ratchet 4, locking bar 3 drives tapered ends 11 extensions and stretches out lock frame 9 until tapered end 11, shown in position I among Fig. 3, door is opened.When unclamping Unlocking knob or extract key out, just locking bar 3 set back rapidly under the effect of spring convergent force together with the tapered end on the spring hanging plate 14 11, shown in position II among Fig. 3.When locking a door, the handle of pulling left and right sides door-plate, tapered end 11 is bumped on lock frame 9, because tapered end 11 is triangular in shape, with producing the component of a horizontal direction, force tapered end 11 to reach among Fig. 3 and locate shown in the I of position, tapered end 11 is in case by lock frame 9, instantaneous horizontal component disappears at once, and tapered end 11 is got back among Fig. 3 under the spring force effect and located shown in the II.In the time need not locking, tapered end 11 in the retraction lock housing 5, is pressed the spring catch nail 8 that is located on the lock housing 5 under the effect of spring 12, spring hanging plate 14 can be blocked, shown in Fig. 3 meta III.When needs are locked a door, spring catch nail 8 to be pulled out, spring hanging plate 14 is shot out housing under the effect of spring expansion force, tapered end 11 is bounce back among Fig. 3 locate shown in the II.
