Description

Twin-lock head lockset

The utility model relates to a kind of lockset.

Existing lockset generally is the monolock head, and promptly one only has a tapered end to lockset, with one key operated or pin.The family that has is for safety, prevents to be opened by other key or key is duplicated by other people, then needs to install in addition a lockset again, so not only repeatedly installs and causes trouble, and influence the attractive in appearance of gate.

The purpose of this utility model is to provide a kind of twin-lock head lockset, and it is low to make it can reach the tapered end mutual opening rate, even and wherein one the key of tapered end duplicated by other people, also can guarantee gate safety, and can also realize interruption-free.

The purpose of this utility model is achieved in that in a kind of twin-lock head lockset with main tapered end and lock body, and an auxiliary tapered end is set above or below main tapered end, and this auxiliary tapered end and main tapered end contact with separately cam mechanism respectively.With the corresponding position of the relative side of keyhole of auxiliary tapered end one knob is being housed, knob can clockwise or rotate counterclockwise, and the connecting rod of knob is inserted in the cam hole of auxiliary tapered end.

Owing to adopt technique scheme, make to the utlity model has following advantage and positive effect:

1, owing in the utility model twin-lock head lockset, has main tapered end and auxiliary tapered end, they contact with separately cam mechanism respectively, therefore two tapered ends need be with two keys, even one is key operated by other people tapered end like this, the possibility that another tapered end also is unlocked is then extremely low, makes the mutual opening rate of tapered end low.

2, general family if this key is replicated, then owing to the main tapered end that is not provided in addition, thereby can stop unsafe factor in decoration or lodge, when hiring out, can only provide the utility model assist the tapered end key.

3, because the auxiliary tapered end side in door of the utility model is equipped with knob, protect function in possessing, indoor occupant can be locked auxiliary tapered end night in bed in door, and the family member who returns night can oneself open door like this, avoids bother night.

The utility model twin-lock head lockset is easy for installation, and twin-lock head and handle once mounting are finished, and have overall appearance.

Below in conjunction with drawings and Examples the utility model is further specified

Fig. 1 is the outline drawing of the utility model twin-lock head lockset

Fig. 2 is auxiliary lock header structure figure

Among the figure, 1. main tapered end 2. auxiliary tapered end 3. lock bodies 4. knobs 5. cams 6. handles 7. auxiliary lock head component

The utility model twin-lock head lockset shown in Figure 1 has main tapered end 1, auxiliary tapered end 2 and handle 6, and main tapered end 1 has three interlock side's tongues, and auxiliary tapered end 2 has a square tongue.Main tapered end 1 and auxiliary tapered end 2 are respectively by separately cam mechanism driving, knob 4 is equipped with in a side relevant position in the door of auxiliary tapered end, clockwise or be rotated counterclockwise knob 4, the square tongue of auxiliary tapered end is regained or stretched out lock body 3.

Fig. 2 has provided the structure of auxiliary tapered end, the square tongue of auxiliary tapered end 2 links to each other with auxiliary lock head component 7, have groove on the square hyoplastron of auxiliary lock head component 7, the opening part both sides of groove are relative inclined-plane, when the position of groove should make auxiliary tapered end cam 5 rotate, its shifting part can contact with two inclined-planes of groove respectively.

The course of work of auxiliary tapered end is as follows: when turning the key in the lock, key is put in cam 5 holes of auxiliary tapered end, key turns clockwise, cam 5 is rotated, inclined-plane, right side on the square hyoplastron groove of the auxiliary lock head component 7 of its shifting part promotion, auxiliary lock head component 7 is moved right together with the square tongue of auxiliary tapered end 2, and the side's of making tongue is recovered in the lock body 3, thereby can open the gate.When locking a door with key, key is rotated counterclockwise, makes shifting part promote inclined-plane, left side on the square hyoplastron groove of auxiliary lock head component 7, thereby will assist lock head component 7 to be moved to the left together with the square tongue of auxiliary tapered end 2, square tongue is stretched out outside the lock body 3, the gate is pinned.

When using knob 4 at indoor unlatching or pinning gate, by clockwise or counterclockwise turn knob 4, the connecting rod actuating cam 5 that knob 4 is inserted in the cam hole of assisting tapered end 2 rotates, thereby produces the key operated or identical course of action in pinning gate of above-mentioned usefulness.

The utility model is applicable to the common door and the security door of residential houses, office, unit etc.
