Description

Latch lock

The present invention relates to general latch lock (cylinder lock), particularly the latch lock of shaft lock lever lock pattern.

The latch lock of at present existing many different types of shaft lock lever lock patterns.In order to improve its safety, designed the spring catch that in each chamber, has a plurality of coaxial pins.About the description of this class lock, United States Patent (USP) the 593rd, 436,1,095,500,3,818,732 and 4,142, all open in No. 389.Though the safety of this lock is higher since they in fit on and control and use exceedingly difficult and time-consuming, thereby cost is also very high.

The objective of the invention is to seek to provide a kind of latch lock of high safety, have a plurality of pins in its each chamber, and can overcome many shortcomings of existing latch lock of the same type.

The latch lock that a preferred embodiment according to the present invention provides comprises: shell and configuration in the enclosure and with its work plunger in relative rotation; Be positioned at first group of chamber of shell and be positioned at second group of chamber of plunger, their arrangement mode is when plunger is in first gyrobearing with respect to shell, the coaxial extension in corresponding chamber in each chamber in first group of chamber and the second group of chamber.More than first a yuan of pin composite member is configured in described first group of chamber and is configured in described second group of chamber with more than second a yuan of pin composite member, more than first yuan of pin composite member comprises that an outer pin subelement with an axial recess and one can select the inner peg element of axial orientation with respect to outer pin subelement, and can keep off and block the inner peg element and it is not broken away from outer pin subelement and prevent the device that itself and outer pin subelement are aimed at not according to predetermined way.

According to a preferred embodiment of the present invention, inside and outside pin element is loaded by elasticity each other.

In addition, according to a preferred embodiment of the present invention, the device that retaining blocks the inner peg element comprises the part that extends axially of an inner peg element, and the part that outer pin subelement can be passed in this extension is extended and slided, and its structure can prevent to break away from outer pin subelement in the ordinary course of things.

The polynary pin composite member that application has blocking device is of the present invention one big feature, and it can make the assembling of lock realize automation or semi-automation, has simplified the control and the use of lock widely.

In addition,, be carved with many grooves on the periphery of plunger, thereby between shell and plunger, limit a non-directional shear line according to a preferred embodiment of the present invention.

Can understanding more all sidedly be arranged to the present invention from detailed description below in conjunction with accompanying drawing, wherein:

Fig. 1 is the side sectional view according to the spring catch of the structure of a preferred embodiment of the present invention and action.

Fig. 2 is the lock represented among Fig. 1 amplification view along II among Fig. 1-II line.

Fig. 3 A, 3B and 3C have represented three kinds of embodiment that can select for use arbitrarily according to the polynary pin composite member of a preferred embodiment structure of the present invention and action.

Fig. 4 A, 4B and 4C have represented three kinds of embodiment that can select for use arbitrarily according to the polynary pin composite member of another preferred embodiment structure of the present invention and action.

Fig. 5 A, 5B and 5C have represented three kinds of embodiment that can select for use arbitrarily according to the polynary pin composite member of another preferred embodiment structure of the present invention and action.

Fig. 1 and Fig. 2 represent to comprise a shell 10 according to the latch lock of a preferred embodiment structure of the present invention and operation, limit a plunger 12 in it.As shown in fig. 1, be carved with many grooves on plunger 12 peripheries between shell and plunger, to form a non-directional shear line.

Shell 10 and plunger 12 have corresponding cavity 14 and plunger cavity 16, and plunger cavity 16 communicates with a locked groove 18, have a key 20 to insert in the locked groove.Cavity 14 communicates with the outer surface of shell 10, preferably by dismountable band 22 sealings.Shell 10 preferably comprises a thread escutcheon 26 and a quenching pin 28.The effect of pin 28 is to prevent from the jewel hole of latch lock is destroyed.

Being configured in each plunger cavity 16 is one group of polynary plunger pin sub-portfolio part 30, and it comprises a core pin element 32 and a hollow pins element 34, and a hole 36 is arranged on this hollow pins element, passes this hole core pin element 32 and can extend slip.In addition, if the suitable inside and outside control panel 38 and 24 that also can dispose correspondence.

Being configured in each cavity 14 is one group of polynary casing pin sub-portfolio part 40, and it comprises a core pin element 42 and a hollow pins element 44, and a hole 46 is arranged on this hollow pins element, and the prolongation 48 that passes this hole core pin element 42 can extend slip.Prevent that core pin element 42 from throwing off is of the present invention one big feature from hollow pins element 44.In this embodiment that exemplifies, thus prevent this disengagement be with the top 49 of prolongation 48 in addition broadening it can not be realized by hole 46.In addition any other prevents that core pin element 42 from throwing off and keep them and can use in the appropriate method with the uranium aligned position roughly from hollow pins element 44.

According to the present invention, a compression spring 50 is installed between core pin element 42 and the hollow pins element 44, makes top 49 close to hole 46 thereby so just impel two elements to be in corresponding orientation.Another compression spring 52 is contained between hollow pins element 44 and the band 22, makes whole polynary casing pin sub-portfolio part towards shear line and plunger cavity 16.

Of the present invention one big feature is: because the structure of casing pin sub-portfolio part can prevent undesirable and accidental disengagement and not aim at, therefore this assembling as the lock among Fig. 1, control and use have just been simplified widely, thereby can realize the assembly automation of lock and pin composite member, reduce cost of production significantly.
