Abstract

The utility model relates to an end face spring lock and key matching with lock bodies for spring locks. The utility model is characterized in that a string hole on a locking head ring and the axial line of the string hole corresponding to a lock core are arranged in the method of parallel with the axial line of the lock core. The head of a key is a hollow cylinder. The upper end of the outer circumference of the hollow cylinder is provided with a half slot corresponding to the string hole on the lock core in axis direction. The utility model has the advantages of novel structure, strong confidentiality and high safety.

Description

End face spring lock and key

The utility model relates to lockset, is a kind of various cylinder lock lock bodies supporting tapered end and key of being suitable for.

Existing common spring lock, insurance ball lock head, its principal character is to have a row or multi-row pellet shot from a slingshot hole perpendicular to axis accordingly on lock core and the tapered end (tapered end ring), the quantity in every row's pellet shot from a slingshot hole is not limit, mix unit, flat pellet shot from a slingshot and spring in the pellet shot from a slingshot hole, simultaneously, have on the lock core for the key lock shaft to the trough that inserts.The key that matches with this tapered end is a kind of tabular key, has the key and and the corresponding teeth groove in pellet shot from a slingshot hole site that match with lock core groove on it.This its pellet shot from a slingshot with radially be provided with, key is with the tapered end of axial insertion, because of using for a long time, grasped gradually by people, makes confidentiality out of control, the safety reduction of lockset.

The purpose of this utility model is in order to provide a kind of structure novel, strong security, safe and reliable end face cylinder lock head and the key that matches with it are for various supporting as lock bodies such as door lock with knob, two flapper lock, slotting ostium lock, furniture lock, copper iron pad lock, bicycle locks.

For achieving the above object, the utility model has changed the pellet shot from a slingshot arrangement mode of ball lock head, become pellet shot from a slingshot and radially be set to axial setting, concrete structure is, pellet shot from a slingshot hole on the tapered end ring and the pellet shot from a slingshot hole on the lock core correspondingly all are provided with the mode that the axis of lock core parallels with its axis.

Because tapered end done structural new design, the inventor has also done corresponding design to the key that tapered end therewith matches, and key head is designed to hollow cylindrical, have with axis direction on the columniform edge with lock core on the corresponding half slot in pellet shot from a slingshot hole.For making things convenient for key, afterbody is designed to tabular handle.

The utility model is described in further detail below in conjunction with the accompanying drawing illustrated embodiment.

Description of drawings:

Fig. 1 is the structure sectional view of tapered end in the utility model.

Fig. 2 is the head construction sectional view of key in the utility model.

Fig. 3 is the vertical view of Fig. 2.

See that by lock head structure figure shown in Figure 1 tapered end ring 1 is assembled in lock core 2 bottoms that have the shaft shoulder, the inner ring of tapered end ring 1 and lock core 2 movingly, outer ring and cover tubular tapered end 3 close-fittings; On the lock core 2 on shaft shoulder edge plane axially to be distributed with the pellet shot from a slingshot hole equably, wherein be provided with the different cylinder-shaped marble of length 6, and with tapered end ring 1 on corresponding one by one with axial equally distributed pellet shot from a slingshot hole, in the pellet shot from a slingshot hole of this tapered end ring 1, mix the pellet shot from a slingshot 7 and the marble spring 8 of tape spool shoulder respectively.4 is the tabular handle of key among the figure, and 5 is key bit.

Structure by Fig. 2, key bit shown in Figure 3 sees, key bit 5 is for head is hollow cylindrical, have with axis direction on this cylindrical outward flange with lock core 2 on the different half slot 9 of the corresponding depth in pellet shot from a slingshot hole.

Aforesaid tapered end and key, when a key inserts lock core, the end face of the half slot of key head periphery is subdued each cylinder-shaped marble in the lock core 2 pellet shot from a slingshot holes respectively, make the lower surface of each cylinder-shaped marble reach the shaft shoulder of lock core 2 and the interface location of tapered end ring 1, then the interface location that interfacial pellet shot from a slingshot 7 promptly is depressed into tapered end ring 1 is stretched out in tapered end ring 1 Central Plains, so far, reverse key handle 4, because the flange of key handle head embeds in the keyway of lock core 2 upper ends, just can drive lock core 2 left sides, it is moving to turn right, by the rotation of lock core 2, drive dead bolt and stretch and the unlatching and the locking of realization lockset.

The utility model has the advantages that, novel structure, strong security, safe and reliable, and have that volume is little, anufacturability good and the characteristics of economical with materials.

Claims

1, a kind of end face cylinder lock head, comprise the tapered end ring 1 that is fixedly installed in the cover tubular tapered end 3, the lock core 2 that matches with tapered end ring 1 and be arranged on tapered end ring 1 and lock core 2 pellet shot from a slingshot holes in pellet shot from a slingshot 7 and marble spring 8, it is characterized in that the pellet shot from a slingshot hole on pellet shot from a slingshot hole on the tapered end ring 1 and the corresponding with it lock core 2 all is provided with the axis mode of paralleling of lock core 2 with its axis.

2, a kind of and key that matches of tapered end according to claim 1 is characterized in that key 5 heads are hollow cylindrical, have with axis direction on the columniform edge with lock core 2 on the corresponding half slot 9 in pellet shot from a slingshot hole, afterbody is tabular handle.
