Description

Puzzle padlock

The utility model relates to a kind of lockset, especially relates to a kind of cipher hang lock.

Padlock commonly used at present all is with key operated cylinder lock generally, it is simple in structure, applicable surface is big, safe and reliable, but this be locked in to have only with key under the situation of not destroying himself structure just can open, this brings difficulty with regard to the use of giving some specific occasions, and is particularly outstanding aspect the locking of boxcar and container.The locking lead sealing of boxcar at present, anti-theft capability is poor, but can not because the problem of delivering goods and receiving and existing key to transfer between the both sides is cumbersome, can not be accepted by the shipping client with general padlock.Now more existing cipher hang locks, but their general structures are all complicated, therefore cost is higher, in addition because its lock core adopts special construction, therefore the dial that has a numeral can produce a kind of other digital sound that differs from when turning to the password figure of cipher hang lock, and the people who does not have password so only need just can open lock by distinguishing sound.

The purpose of this utility model is to provide the cipher hang lock that a kind of structure is comparatively simple, be exclusively used in some special occasions.

The utility model is a kind of cipher hang lock, and it comprises a lock body and the suspension ring that can be connected with described lock body locking, and described lock body comprises at least one dial, and described lock body also comprises two handles, a mandrel, a sleeve pipe; One end of described suspension ring is fixed on the described handle, and an end of described mandrel (or described sleeve pipe) is fixedly installed on the inner side end of described handle; Near to or in contact with described another handle, an end of described sleeve pipe (or described mandrel) is fixedly installed on the inner side end of described handle the other end of described suspension ring when the padlock locking; Have on described mandrel along its axially extended radial flange, described flange is provided with and at interval and radial groove that circumferentially extend on the edge described dial equivalent, equidistant; Have on described sleeve pipe along its axially extended open slot, described mandrel is inserted in the described sleeve pipe slidably and makes described flange be arranged in described open slot; Described dial has flat-disk shape portion and periphery has sidewall, the central authorities of described discoid portion are provided with a through hole and offer a radial groove along the edge of described through hole, and described dial is enclosed within outside the described sleeve pipe and makes discoid the movable warp-wise groove that embeds on the described flange of described dial; The position of corresponding described radial groove thereon is provided with a password figure on the periphery of described dial, and the position corresponding to described flange on the periphery of described handle is provided with a mark.

The utility model has the advantages that simple in structurely, it has abandoned the complex mechanical structure of the lock core of original coded lock, makes processing more convenient, has reduced manufacturing cost; Vi have high safety, owing to be to open lock by groove and cooperating of flange, so dial feel when rotating is identical with sound all the time.

Below in conjunction with accompanying drawing most preferred embodiment of the present utility model is made detailed description, therefrom can see the more advantage of the utility model.

Fig. 1 is an elevation of the present utility model, that have partial cutaway;

Fig. 2 is the sectional view along " A-A " line among Fig. 1;

Fig. 3 is the sectional view along " B-B " line among Fig. 1.

Now referring to Fig. 1,2 and 3, a kind of cipher hang lock of the present utility model, it comprises lock body 7 and suspension ring 4, and lock body 7 is by two handles 1 and 2, and mandrel 3, sleeve pipe 6 and four dials 5 are formed.Be shaped on opening on the side face of handle 1 and be positioned at U-shaped groove 8 on the inner side end of handle 1, and offer an axial blind hole 9 on its inner side end, an end of sleeve pipe 6 is fixedly installed in the axial blind hole 9 by holding screw 10.Certainly U-shaped groove 8 is not essential.Have on the side face of handle 2 and have an axial blind hole 12 on a radial blind holes 11 and its inner side end, an end of suspension ring 4 is fixedly installed in the radial blind holes 11 by pin 13, and an end of mandrel 3 is fixedly installed in the axial blind hole 12.Certainly an end, mandrel 3 and the sleeve pipe 6 of suspension ring 4 also can be made with handle 1 and 2 one, perhaps are fixed together with additive method.On the sleeve pipe 6 of handle 1 outside, be shaped on the radial opening groove 14 that extends along its axis direction, on the mandrel 3 of handle 2 outsides, has the radial flange 15 that extends along its axis direction, be shaped on four equidistant at interval grooves 16 vertically on the flange 15, mandrel 3 can cooperate axially slidably and is inserted in the sleeve pipe 6 and flange 15 is positioned at open slot 14.Dial 5 has flat-disk shape portion 17 and periphery has sidewall 18, offer a through hole 19 in the plate-like portion 17 and offer a radial groove 20 along the edge of through hole 19, four dials 5 are enclosed within outside the sleeve pipe 6 successively in the same way and 17 activities of plate-like portion are cooperated and embed grooves 16, the other end of sleeve pipe 6 has the flange 22 of outside turnover, flange 22 can be a ring-type, also can be along the circumference spaced set in order to block dial 5.On corresponding to groove 20 dial peripheries, a password figure is set and on handle 2 peripheries, a mark 21 is set corresponding to flange 15, like this when the password figure on four dials 5 forward to simultaneously with mark 21 in line during the position all grooves 20 just interpenetrate, flange 15 can therefrom pass through, so just can handle 1,2 is separated from each other, thus lock is opened.When the lock locking, mandrel 3 is inserted in the sleeve pipe 6, thereby the other end of suspension ring 4 is embedded in the U-shaped groove 8, rotating driver plate 5 then, make flange 15 and groove 20 dislocation, so just with the padlock locking.

Certainly, the number of dial 5 also can be 1,2,3 or 5 etc.
