Description

Has lockset with stepped keyhole core

The utility model belongs to lock, particularly a kind of lockset that has with stepped keyhole core.

The lockset of commonly using, the keyhole of its core are generally and are rectangular poroid, that is the hole wall of keyhole is horizontal plane or vertical plane.Therefore, each of core promoted the fitly protruding keyhole inside that is exposed to of system, makes the neat keyhole of the as easy as rolling off a log foundation of burglar do a judgement, by the unlocked by universal key lockset, makes lockset upgrade its due anti-theft feature of forfeiture.

The lockset of commonly using, its key is an indentation with promoting the end face that cooperates.Key can be extracted out after must turning to locking condition.Key insert turn to leave locking condition after, push away lock in it and promptly can't retreat, thereby the blocking that key is promoted can't be extracted out.Particularly since the lockset commonly used under released state, core and sleeve and no-fix make the user judge by accident easily, cause and use sizable inconvenience.

The purpose of this utility model provide a kind of theftproof strong, easy to use have a lockset with stepped keyhole core.

The utility model comprises core, with the sleeve of core fit, be sleeved on sleeve outer sheath body and key; Core inside is provided with stepped keyhole, core back segment wall is provided with and is through to keyhole and is the first axial kingpin bore, is equipped with distribution in the kingpin bore, and the core leading portion is provided with flange, the flange rear end face is provided with and is the second axial secondary pin-and-hole, is equipped with distribution in the secondary pin-and-hole; Sleeve is and the hollow cylinder of core fit that its side wall surface is provided with the main card drilling that runs through corresponding to kingpin bore on the core, is equipped with second spring and blocking pin in the main card drilling; The barrel forward end face is provided with the secondary blocking hole corresponding to secondary pin-and-hole on the core, is equipped with the 3rd spring and blocking pin in the secondary blocking hole; The shape of key which is provided with the first axial fitting face and the second axial fitting face that correspond respectively to kingpin bore and secondary pin-and-hole corresponding to the keyhole on the core.

Wherein:

Be equipped with first spring in the secondary pin-and-hole of core; First the elastic coefficient is less than the coefficient of elasticity of the 3rd spring; The locating hole of secondary pin-and-hole on the barrel forward end face is provided with when release corresponding to core.

The C shape clasp that makes core and tube-in-tube structure is housed on the core

Because the utility model comprises core, sleeve, sheath body and shape and the key that is provided with stepped keyhole; Be respectively equipped with on the core be first, second axially and with the major and minor pin-and-hole that keyhole runs through, in major and minor pin-and-hole, be respectively equipped with distribution; Be provided with the major and minor blocking hole that corresponds respectively to major and minor pin-and-hole and be equipped with second, third spring and blocking pin respectively with the sleeve of core fit; Shape is provided with first and second the axial fitting face that corresponds respectively to major and minor pin-and-hole corresponding to the key of keyhole, because of the keyhole wall is stepped, the burglar can't be differentiated when illegal release respectively promote the relative datum position, increased the degree of difficulty of release, add and have two axial blockings simultaneously, except the intensity that increases the lockset locking, further increased the difficulty of illegal release; And after in key inserts keyhole, no matter core turns to any one position, key all can be extracted easily, can promote the convenience that lockset uses greatly, and not only theftproof is strong, and easy to use, thereby reaches the purpose of this utility model.

Below in conjunction with accompanying drawing the utility model is further elaborated.

As shown in Figure 1, the utility model comprise core 10, with the sleeve 20 of core 10 fits, be sleeved on sleeve 20 outer sheath body 30 and key 40.Core 10 inside are provided with stepped keyhole 11, core 10 back segment walls are provided with and are through to keyhole 11 and are the first axial kingpin bore 12, be equipped with in the kingpin bore 12 and promote 13, core 11 leading portions are provided with flange 14, flange 14 rear end faces are provided with and are the second axial secondary pin-and-hole 15, are equipped with in the secondary pin-and-hole 15 to promote 13 and first spring 16.

Sleeve 20 is a hollow cylinder, in it week just can with core 10 fits, its side wall surface is provided with the main card drilling 21 that runs through corresponding to kingpin bore 12 on the core 10, is equipped with second spring 22 and blocking pin 23 in the main card drilling 21.Sleeve 20 front end faces are respectively equipped with secondary blocking hole 24 and the locating hole 25 corresponding to secondary pin-and-hole 15 on the core 10, are equipped with the coefficient of elasticity of the coefficient of elasticity of the 3rd spring 26 and blocking pin 23, the three springs 26 greater than first spring 16 in the secondary blocking hole 24.

The shape of key 40 which is provided with the first axial fitting face 41 and the second axial fitting face 42 that correspond respectively to kingpin bore 12 and secondary pin-and-hole 15 corresponding to the keyhole on the core 10 11.

As shown in Figure 2, after core 10 closes with sleeve 20, made up by C shape clasp 50 spacing, and in sleeve 20 outer rim fit sheath bodies 30, so that blocking pin 23 is limited in the main card drilling 21.When the utility model is locking condition, just can make kingpin bore 12 and main card drilling 21 and secondary pin-and-hole 15 and 24 contrapositions respectively of secondary blocking hole; By the elastic force of second spring 22, pass 23 protruding the revealing to kingpin bore 12 of blocking pin in the main card drilling 21, form the first axial blocking relation; By the elastic force of the 3rd spring 26, pass blocking pin 23 protruding dew in the secondary blocking hole 24 to secondary pin-and-hole 15, form the second axial blocking relation.As shown in Figure 3, after key 40 inserts keyhole 11 cooperations, respectively promote 13 by key 40 passing, blocking pin 23 can be passed to main card drilling 21 and kingpin bore 12 and secondary blocking hole 24 and secondary pin-and-hole 15 flush position, make key 40 be able to core 10 is turned to unlocked position, and do not need key 40 to cooperate, core 10 can be turned to locking position from unlocked position.

Because keyhole 11 walls are stepped, therefore, the burglar can't be differentiated when illegal release respectively promote 13 relative datum positions, increased the degree of difficulty of release, add and have two axial blockings simultaneously, except the intensity that increases the lockset locking, further increased the difficulty of illegal release.

As shown in Figure 3, also because keyhole 11 walls are stepped, therefore after key 40 inserted in the keyhole 11, no matter core 10 turns to any one position, key 40 all can be extracted easily, can promote the convenience that lockset uses greatly.

As shown in Figure 4, when the utility model was locking condition, the blocking pin 23 in the secondary blocking hole 24 just was displaced in the secondary pin-and-hole 15 and forms the second axial blocking.As shown in Figure 5, after core 10 turned to unlocked position, the distribution 13 in the secondary pin-and-hole 15 was subjected to the ejection of first spring 16, can embed in the locating hole 25, and core 10 is positioned unlocked position.After core 10 is rotated by the application of force, push away lock 13 and promptly can break away from locating hole 25, can make the user confirm that easily core 10 is positioned at unlocked position, and core 10 can be fixed in unlocked position temporarily, return to locking position unintentionally to avoid core 10.

During the utility model assembling, utilize the spacing of C type clasp 50, make core 10 rapid more, convenient with the assembling of sleeve 20.
