Abstract

The utility model discloses a bidirectional clutch for a key cylinder, and relates to the technical field of key cylinder clutches. The bidirectional clutch for the key cylinder disclosed by the utility model comprises an empty medial rotation shifting fork, a clutch gear, a first empty lateral rotation shifting fork and a latch bolt dial wheel, wherein one end of the empty medial rotation shifting fork is provided with a boss, and a groove is formed in the other end of the empty medial rotation shifting fork; the clutch gear is matched with the boss end of the empty medial rotation shifting fork; the first empty lateral rotation shifting fork is matched with the groove end of the empty medial rotation shifting fork, the first empty lateral rotation shifting fork is matched with the groove of the empty medial rotation shifting fork; the latch bolt dial wheel is connected with the first empty lateral rotation shifting fork and can be clamped in the empty medial rotation shifting rock, the other end, corresponding to the empty medial rotation shifting fork, of the latch bolt dial wheel is groove-shaped, and a clutch pin is arranged on one side of the empty medial rotation shifting fork; a clutch spring penetrates through the clutch pin, and the end of the clutch pin is further provided with a copper sleeve for preventing the clutch spring from propping outwards. A second empty lateral rotation shifting fork and a square shaft in the bidirectional clutch disclosed by the utility model can be clamped in the latch bolt dial wheel or the clutch gear as an integral body, thus the opening direction of a conversion door can be achieved just by changing the position of the square shaft.

Description

Lock core bidirectional clutch

Technical field

The utility model relates to lock core clutch device technical field, relates in particular to lock core bidirectional clutch.

Background technology

At present, a door minute left side is driveed with the right side and is opened, and lock will have a left side to drive with the right side to open accordingly.When have want transformation door open to time just need to again change lock or dress lock again, so will be cumbersome.

Utility model content

The utility model in prior art when want transformation door open to time to again change lock or again fill the trouble that lock strap comes and lock core bidirectional clutch is provided, this lock core bidirectional clutch only need carry out that simple assembling can transformation door open to.

The technical solution of the utility model is as follows:

Lock core bidirectional clutch comprises sky medial rotation shift fork, there is boss described empty medial rotation shift fork one end, the other end is fluted, there is suitable clutch gear with the boss end of empty medial rotation shift fork, there is the first suitable sky to revolve outer shift fork with the groove ends of empty medial rotation shift fork, it is suitable that described the first sky revolves the groove shapes of outer shift fork and empty medial rotation shift fork, revolve with described the first sky the latch bolt thumb wheel that outer shift fork is connected and can be sticked in sky medial rotation shift fork, the described latch bolt thumb wheel other end corresponding with empty medial rotation shift fork is groove type, there is the second sky that is sticked in latch bolt thumb wheel groove to revolve outer shift fork, the second sky revolves in outer shift fork fluted, in groove, be inserted with square shaft, square shaft plays securing member by the spacer pin of bottom, the second sky revolves outer shift fork and square shaft also can be sticked in the clutch gear other end corresponding with empty medial rotation shift fork as a whole, one side of described empty medial rotation shift fork has on-of pin, described on-of pin has clutch spring to pass, on-of pin end also have copper sheathing rise restriction clutch spring outwards eject.

The beneficial effects of the utility model are: the square shaft in the utility model lock core bidirectional clutch can be sticked in the second sky and revolve outer shift fork or clutch gear, the position that so only needs to change square shaft can reach transformation door open to.

Accompanying drawing explanation

Fig. 1 is the structure chart of the utility model lock core bidirectional clutch.

The specific embodiment

For better explanation the utility model, existing in conjunction with the embodiments and accompanying drawing be further described.

As illustrated in fig. 1 and 2, lock core bidirectional clutch comprises sky medial rotation shift fork 2, there is boss described empty medial rotation shift fork 2 one end, the other end is fluted, there is suitable clutch gear 1 with the boss end of empty medial rotation shift fork 2, there is the first suitable sky to revolve outer shift fork 3 with the groove ends of empty medial rotation shift fork 2, it is suitable with the groove shapes of empty medial rotation shift fork 2 that described the first sky revolves outer shift fork 3, revolve with described the first sky the latch bolt thumb wheel 4 that outer shift fork 3 is connected and can be sticked in sky medial rotation shift fork 2, described latch bolt thumb wheel 4 other end corresponding with empty medial rotation shift fork 2 is groove type, there is the second sky that is sticked in latch bolt thumb wheel 4 grooves to revolve outer shift fork 5, it is interior fluted that the second sky revolves outer shift fork 5, in groove, be inserted with square shaft 7, square shaft 7 plays securing member by the spacer pin 6 of bottom, the second sky revolves outer shift fork 5 and square shaft 7 also can be sticked in clutch gear 1 other end corresponding with empty medial rotation shift fork 2 as a whole, one side of described empty medial rotation shift fork 2 has on-of pin 10, described on-of pin 10 has clutch spring 8 to pass, on-of pin 10 ends also have 9 restriction clutch springs 8 of copper sheathing outwards to eject.

Operating principle of the present utility model:

As shown in Figure 1, the second sky revolves outer shift fork 5 and square shaft 7 composition integral body are sticked in sky medial rotation shift fork 2, when on-of pin 10 is pressed into sky medial rotation shift fork 2, the first sky revolves in the groove that outer shift fork 3 falls into sky medial rotation shift fork 2, drive again latch bolt 4, the second sky to revolve outer shift fork 5 and square shaft 7 interlocks, can realize the action that L.H.flapped door lock opens the door within doors, when on-of pin 10 is rebounded by clutch spring 8, now the first outer shift fork 3 and empty medial rotation shift fork 2 are realized and being departed from, and now door is lockable.

As shown in Figure 2, the second sky revolves outer shift fork 5 and square shaft 7 composition integral body are sticked in clutch gear 1, when on-of pin 10 is pressed into sky medial rotation shift fork 2, clutch gear 1 drives the second sky to revolve outer shift fork 5 and square shaft 7 interlocks, can realize R.H.flapped door lock opens the door within doors, when on-of pin 10 is rebounded by clutch spring 8, now the first outer shift fork 3 and empty medial rotation shift fork 2 are realized and being departed from, and now door is lockable.

The utility model only need revolve the second sky outer shift fork 5 and square shaft 7 and be installed on sky medial rotation shift fork 2 or clutch gear 1, can realize L.H.flapped door or R.H.flapped door.
