Description

Steel wire lock

The utility model relates to lockset, is the cable wire lock that a kind of locking bar is made with cable wire.

Existing being seen cable wire lock is made of bowden cable of using as locking bar and the lock body that is provided with tapered end.Bowden cable has a fixed end and a locking bar end, cable wire fixed end end be one contain one for build-in with the fixed bar of concave ring groove, locking bar end end is one to contain a chimeric concave ring groove of locking bolt for tapered end.Seen three holes from the lock body appearance, the one, place fixing rope hole for the cable wire fixed end, the 2nd, place the lockhole of locking for cable wire locking bar end, the 3rd, the tapered end hole of tapered end is set.Cable wire is mounted in the concave ring groove with rivet after being set in Suo Kongzhong with its fixed end, promptly cable wire one end is connected on the lock body; The locking bar end of cable wire then can freely insert or break away from lockhole, after in the lockhole that cable wire locking bar end is inserted lock body, with the core of key turns tapered end, card tip translation that then will be relevant with core in the chimeric concave ring groove of going on the locking bar; Otherwise promptly unblank, cable wire locking bar end can take out from lockhole.The defective that existing this cable wire is latched in is, because the locking bar end is the cylinder of an equal diameter, when it is inserted in the lockhole, has an obvious gaps between locking bar and lockhole, and bolt structure is the card tip and spring, and the card tip embeds in the concave ring groove with translation mode, the very easy gap that utilizes between locking bar and lockhole of picking lock person is then stretched into tagger and to be stirred the card tip therebetween and fall back and reach the purpose of unblanking.In addition, the elongated fixing body of the card tip on the tapered end, less to the fixing power of locking bar.Therefore, the safety of the cable wire of this structure lock is not enough.

The utility model provides a kind of improved cable wire lock, particularly the closedown structure of this lockset has been done improvement, enables to take precautions against effectively from the lockhole picking lock, to increase the safety of lockset.

The utility model of implementing above-mentioned purpose is, a kind of cable wire lock that constitutes by cable wire and the lock body that is provided with tapered end, the cable wire two ends one of this cable wire lock are the fixed end bars, the other end is a locking bar end bar, and be shaped on a concave ring groove of using as build-in at the fixed end boom end, be shaped on a chimeric concave ring groove of locking bolt for tapered end at locking bar end boom end; Lock body is provided with for cable wire fixed end bar and places fixing rope hole, for the lockhole and the tapered end hole that tapered end is set of cable wire locking bar end rod lock.In the design, also design the convex ring body that is made into integration in locking bar end pole-footing portion with concave ring groove, cable wire then is attached on this convex ring body; Simultaneously, tapered end upper end in order to be entrenched in the concave ring groove and the locking bolt of sealed cable wire locking bar end bar is designed to a card tip that is hook-shaped ┐.

For prevent cable wire fixedly between rod end bar and lock body be connected also may be destroyed, the utility model can also design the convex ring body that is made into integration at the root of the fixed end bar with concave ring groove, the convex body that formed by the lock body distortion of build-in then in the concave ring groove.

The utility model has the advantages that because the root of cable wire locking bar end bar is provided with a convex ring body, then when locking bar end bar was inserted lockhole, the lower surface of convex ring body can be covered the slit between lockhole and locking bar, picking lock the person just have no exploits; And, the utility model is designed to hook-shaped structure to the card tip in the lock structure, then its type body is abundant on the one hand, fixing power to cable wire is strong, it must just can leave concave ring groove with the rotation of core on the other hand, so the possibility of having been unblanked with regard to having prevented the picking lock person from stirring the displacement of the card tip with hard things such as iron sheets.In addition, between cable wire fixed end bar and lock body fixedly is with making lock body distortion, and the convex body after the lock body distortion is embedded in the concave ring groove of cable wire fixed end bar, then fixed end to be installed with power strong, and do not subject to the people and strike badly,, only can more strongly decide effect even knock by the outside again.See that thus the utility model has all been made necessary precaution to the possible breakdown point structure of this lockset and improved, and has guaranteed the security performance of lock.

Below in conjunction with accompanying drawing the utility model is described specifically.

The explanation of accompanying drawing drawing:

Fig. 1 is a kind of forward partial sectional view of known cable wire lock.

Fig. 2 is a forward partial sectional view of the present utility model.

Fig. 3 is a three-dimensional exploded view of the present utility model.

Fig. 4 is the schematic perspective view of another embodiment of the utility model.

See also Fig. 1.See that by Fig. 1 known cable wire lock is made of cable wire 1 and the lock body 2 that is provided with tapered end 3.Cable wire 1 has a fixed end bar 10 and a locking bar end bar 11, be shaped on the fixed end bar 10 one for build-in with concave ring groove 100, be shaped on one on the cable wire locking bar end bar 11 for the chimeric concave ring groove 110 of the locking bolt 30 of tapered end 3.Three holes are arranged on the lock body 2, the one, place fixing rope hole 22, two for cable wire fixed end bar 10, supply cable wire locking bar end bar 11 to place the lockhole 20, three of locking, be positioned at lock body 2 root edges for the tapered end hole 24 that tapered end 3 is set; Tapered end hole 24 communicates with lockhole 20; The external diameter of locking bar end bar 11 is consistent with the internal diameter of lockhole 20, and after locking bar end bar 11 placed in the lockhole 20, the locking bolt 30 of tapered end 3 upper ends can be chimeric be gone in the concave ring groove 110; The external diameter of fixed end bar 10 is consistent with the internal diameter in rope hole 22, and fixed end bar 10 is set in back rivet 4 rivet clasps in the rope hole 22.

Seen that by Fig. 2 present embodiment has been set up a convex ring body 111 above the concave ring groove 110 of locking bar end bar 11, cable wire one end is attached on this convex ring body 111; Locking bolt in tapered end 3 upper ends is one to be the card tip 32 of hook-shaped ┐, and the card tip 32 rotates with the core in the tapered end 3.Lock structure so, when inserting locking bar end bar 11 in the lockholes 20, the soffit of convex ring body 111 and lock body 2 have held and have hidden the slit between lockhole 20 and locking bar, and at this moment, the position of concave ring groove 110 just adapts with the horizontal top of blocking the tip 32.Seen by Fig. 2 that again present embodiment has also been set up a convex ring body 101 on the side, right side of the concave ring groove 100 of cable wire fixed end bar 10, the other end of cable wire is attached on this convex ring body 101.After fixed end bar 10 is inserted rope hole 22, a depression is pressed in concave ring groove 100 positions in fixed end bar 10 on lock body 2, make this part distortion of lock body 2 and form the convex body 23 that is entrenched in the concave ring groove 100, the fixed end bar 10 of cable wire 1 is securely fixed on the lock body 2.

Fig. 3 shows the three-dimensional exploded view of present embodiment, and it can make the public more clearly understand its three-dimensional shape and assembly relation.

Seen that by Fig. 4 this is another embodiment of relevant cable wire, this embodiment makes helical form to cable wire 1, can avoid the long problem of cable wire.
