Description

A kind of lock

The utility model relates to a kind of lock.

In the prior art, ever-changing, the numerous and complicated of structure of lock and key, lock adopts manual type with the processing of key more, and output is little, and accuracy rate is low, the cost height; And, lock once the production moulding, its structure is also just fixing, a kind of lock of structure, can only can open by corresponding with it key, if when meeting a plurality of lock, then necessarily be furnished with many keys, it is very inconvenient to carry, when unblanking to use, also often too many because of key, can not find out corresponding key exactly, make troubles to use.

Main purpose of the present utility model is to provide a kind of lock, and itself and key fit structure are simple, and processing can be adopted the automation mode, and output is big, the accuracy rate height, and cost is low.

Secondary objective of the present utility model is to provide a kind of lock, and it can easily be reequiped by ten minutes, and reaches the purpose of key operated a plurality of locks, has made things convenient for carrying and using of key.

For reaching above-mentioned purpose, solution of the present utility model is:

A kind of lock, offer the spring groove of an axis hole and four symmetries on the lock mandrel in lock housing, be nested with three locking plates on four spring grooves, corresponding spring groove of three locking plates and axis hole are offered two spring eyes and a centre bore respectively, three center-hole diameters are by outside to inside dwindling gradually, and first, the interlaced catch that forms symmetry in the spring eye of two locking plates, four little springs, central spring is placed in four spring grooves and the axis hole, turning cylinder, pad is fixed in the lock housing by jump ring, three locking plates and pad two grooves of corresponding lock housing in addition form short slots, the card cylinder supporting with key is housed between groove and the short slot, be fixed in the lock housing by rotating gasket order card cylinder, corresponding three locking plates of card cylinder have three groovings, key from supreme be three sections gradually big cylinders of diameter, its diameter is corresponding with three centre bores, and the cylindrical length of each section is consistent with the spacing of card cylinder grooving.

Above-mentioned pad is provided with a salient point, and this salient point is stuck in the middle of the jump ring breach.

Adopt said structure, the utility model is that three locking plates, four little springs, central spring are set on the lock mandrel in lock housing earlier, wherein, four little springs are respectively by catch block in the spring eye of first and second locking plate, fix by jump ring at the built-in turning cylinder of lock housing, pad again, pack in the groove of the short slot of three locking plates and lock housing and the card cylinder, rotating gasket order card cylinder is fixed in the lock housing then, promptly finishes the whole combination of lock.

The utility model is simple in structure, Dui Ying Key structure is also very simple with it, the structure of the lock mandrel in the lock housing, three locking plates, four little springs, central spring, turning cylinder, pad and jump rings is all standardized, difference between the different locks only is the spacing difference of card cylinder grooving, and the structure of card cylinder and key is also very regular, so, the utility model processing can be adopted the automation mode, output is big, the accuracy rate height, and cost is low.

The utility model is to put into lock housing at last because of the card cylinder, so the card cylinder can take out easily, if during a plurality of lock of buying that the utility model provides, all can take out the card cylinder, the card cylinder that the kerf spacing that changes the outfit is the same like this, needs only with a key, just can drive all locks, make things convenient for carrying and using of key, and need not join many keys, also more economical.

Below in conjunction with drawings and Examples, be further described this reality is novel.

See also shown in Figure 1ly, a kind of lock that the utility model provides is offered on the lock mandrel 1 in lock housing 5 on the spring groove 11 of four symmetries and 12, four spring grooves 11 of an axis hole and is nested with three locking plates 7,8,9.

Three locking plate 7,8,9 corresponding spring grooves 11 and axis hole 12 are offered 71,81,91 and centre bores 72,82,92 of two spring eyes respectively, three centre bore 72,82,92 diameters are by outside to inside dwindling gradually, and interlaced two grooves 51 that form 73,83, three locking plates of catch, 7,8,9 other the corresponding lock housings 5 of symmetry form short slots 74,84,94 in the spring eye 71,81 of first and second locking plate 7,8.

Four little springs 2, central spring 3 are placed in four spring grooves 11 and the axis hole 12, and four little springs 2 are respectively by catch 73,83 (see figure 5) blocks in the spring eye 71,81 of first and second locking plate 7,8.

On lock housing 5, pad 6 is provided with a salient point 61 by jump ring 63 fixed caps for turning cylinder 4, pad 6, and it is fixing that this salient point 61 is stuck in the breach writ of mesne pad 6 of jump ring 63, and 51 of two grooves of pad 6 corresponding lock housings 5 form short slot 62.

The card cylinder 102 supporting with key 10 is housed between the short slot 74,84,94,62 of two grooves 51 of lock housing 5 and three locking plates 7,8,9 and pad 6, by rotating jump ring 63 and pad 6, order card cylinder 102 is fixed in two grooves 51 of lock housing 5, card cylinder 102 corresponding three locking plates 7,8,9 have three groovings 103, card cylinder 102 cross sections can be circular, also can be square or oval.

Key 10 from supreme be three sections gradually big cylinders 101 of diameter, its diameter is corresponding with three centre bores 72,82,92, the length of each section cylinder 101 is consistent with the spacing of grooving 103.

During the utility model assembling, cooperate shown in Fig. 2-4, be on the lock mandrel 1 in lock housing 57,8,9, four little springs 2 of three locking plates, central spring 3 to be set earlier, fix by jump ring 63 at lock housing 5 built-in turning cylinders 4, pad 6 again, in short slot 74,84,94,62 and groove 51, pack into and card cylinder 102, then pad 6 and jump ring 63 are rotated about 90 °, order card cylinder 102 is fixed in the lock housing 5, promptly finishes the whole combination of lock.

When the utility model uses, as Fig. 5, shown in 6, since key 10 from supreme be three sections gradually big cylinders 101 of diameter, its diameter and three centre bores 72,82,92 is corresponding, wherein the diameter of counting first section cylinder 101 from head greater than centre bore 92 less than centre bore 72,82, and the diameter of second section cylinder 101 is greater than centre bore 92,82 and less than centre bore 72, and the like, and the length of each section cylinder 101 is consistent with the spacing of card cylinder 102 groovings 103, key 10 is inserted centre bore 72,82, in 92, key 10 each cylinder 101 promote each locking plate 7 successively, 8,9, make locking plate 7,8,9 mutually form the spacing consistent with three groovings 103 that block cylinder 102, key 10, cylinder 101 can drive three locking plates 7,8,9 rotate thereupon, and state is the shape of unblanking as shown in Figure 6.
