Description

A kind of board-like key and tapered end mechanism thereof

The utility model relates to lock, particularly a kind of board-like key and tapered end mechanism thereof.

Known lock, although it is of a great variety, structure differs, but all unblanks with same mechanism, promptly a strip metal bar shaped key is inserted in the keyhole of tapered end, use the hand key, if the geomery that the pin in surfaces of keys shape and size and the tapered end is arranged matches, key promptly drives kinematic link and rotates, and lock promptly is opened, otherwise key can not rotate, and lock also just can not be opened.But there is following shortcoming in existing lockset: 1. because key cipher is a waveform, belong to a kind of 2D signal, password on the key that the space is set is limited, a key can only be driven a lock, common people all be key chain such as door lock, cabinet lock, office's door lock family together, just have ten eight, even more, hang between waist or in the bag, real be inconvenient.2. because the pin of tapered end inside is arranged in a linear, it is bigger to stir the pirate of the open probability from keyhole, poor stability.

The purpose of this utility model provides a kind of board-like key and tapered end mechanism thereof, and it improves the safety of lock, and makes a board-like key can open the lock of the same type of multiple different passwords.

For achieving the above object, the solution of the utility model employing is: tapered end mechanism is made up of tapered end set casing, rotational pin stroma, steady pin stroma, handle, kinematic link, spring.Fixator pins is fixedly installed on the inwall of tapered end set casing, has the pinhole that corresponds to each other and communicate on steady pin stroma and the rotational pin stroma, the pin kinematic link wherein is housed fixedlys connected with the rotational pin stroma.Be fixed with straight gear on the inwall of tapered end set casing.In the tapered end set casing, be with a tapered end and rotate shell, tapered end rotates shell fixedlys connected with handle, have a flat key groove for board-like key insertion on its sidewall, fixedly install rotor plate on its inwall, have on the rotor plate with the rotational pin stroma on the corresponding hole of pinhole, be provided with back-moving spring between rotor plate and the rotational pin stroma.Board-like key is by what the material that certain degree of hardness is arranged was made certain thickness surface plate to be arranged, and has the different hole of the degree of depth above.

Because the password that holds of board-like key is a kind of three dimensional signal, password that the space is set is very big, can make a key can open the lock of multiple different passwords at a password that many locks are set on the key simultaneously.Because the pin of tapered end mechanism is arranged arbitrarily in the plane, the tapered end inner cipher that the space is set is big, can effectively prevent pirate of the open, safety is improved.

Below in conjunction with accompanying drawing enforcement of the present utility model is described in further detail:

Tapered end mechanism as shown in Figure 1 and Figure 2 is screwed on tapered end set casing 2 inwalls and is connected and fixed pin seat 6.Tapered end rotates to be screwed on shell 3 inwalls and connects rotor plate 8.Be provided with between rotor plate 8 and the rotational pin stroma and be through pin 10 small diameter parts and divide back-moving spring 13 on 11, make tapered end rotate shell 3 and pin 10 resets.Be fixed with straight gear on the inwall of tapered end set casing 2, rotational pin stroma 7 is connected with steady pin stroma 6, have the pinhole 17 that corresponds to each other and communicate on steady pin stroma 6 and the rotational pin stroma 7, pin 9, pin 10 and back-moving spring 14 wherein are housed, and this spring resets the pin 9,10 in the pinhole 17.One end evagination of pin 9 also is connected with spring 14.In case shotpin 9 and pin 10 are ejected pinhole 17 by spring 14, the length sum of the particle size part of pin 9 and pin 10, equate with the thickness sum of steady pin stroma 6 and rotational pin stroma 7, the small diameter part of the in-house pin 10 of tapered end divides 11 length identical, when pin 9 and pin 10 were resetted, both sides spring 4,13 can not interact by pin.Kinematic link 15 is fixedlyed connected with rotational pin stroma 7.The specification of kinematic link 15 is the same with the kinematic link of existing tapered end, energy and the supporting use of existing lock body.Handle 4 is fixedlyed connected with rotation lock head capsule 3.Have a flat key groove 16 for board-like key insertion on rotation lock head capsule 3 sidewalls.Tapered end rotates an end margin evagination of shell 3, tapered end rotates to be screwed on shell 3 inwalls and connects rotor plate 8, have pinhole 17 corresponding holes 18 on the rotor plate 8 with rotational pin stroma 7, stud with pin cap 12 in the hole, as shown in Figure 7, have the aperture on the pin cap 12 and divide 11 the identical hole 19 of diameter, the small diameter part branch of pin 10 is passed in hole 19, make small diameter part divide 11 can only move in the horizontal direction with the small diameter part of pin 10.When unblanking, the key interpolation is gone into board-like key, make key porose one facing to pin, inwardly depression of handle is to the top, at this moment the small diameter part of pin 10 divides the 11 tops board-like key 5 of conflicting, when board-like password on the key is correct, pin 10 and the contact surface of pin 9 and the contact surface of rotational pin stroma 7 and steady pin stroma 6, at grade, at this moment swing handle 4, rotation lock head capsule 3 just drives rotational pin stroma 7 and rotates, rotational pin stroma 7 drives kinematic links 15 and rotates, and lock promptly is opened, when the password of board-like key not to the time, rotational pin stroma 7 can't rotate, and lock is not just opened.

As Fig. 3, Fig. 4, Fig. 5, Fig. 6, board-like key shown in Figure 3, it is by what metal material was made certain thickness surface plate to be arranged, and has the hole 20 of different depth above, it and the supporting use of tapered end mechanism, one protuberance 21 is arranged, the position that its control key inserts tapered end on one end of key.The password of Fig. 3, Fig. 4, key shown in Figure 5 is arranged on simultaneously shown in Figure 6 on the key board-like, as shown in Figure 6, as long as wherein the center of circle of the password of each key does not overlap, key shown in Figure 6 just can be opened three locks that above-mentioned three keys are opened.When the center of circle of the password of the center of circle of the password of a key wherein and another key overlaps, as shown in Figure 8, can change the wherein aperture of more shallow password, make the aperture of the aperture in the big hole 20 of the board-like degree of depth on the key less than the little hole 20 of the degree of depth, and change pin 10 corresponding and supporting pin cap 12 thereof with it, make small diameter part divide 11 diameter consistent, can not change the password of key and tapered end like this, solve the problem that password overlaps with the aperture of corresponding aperture 20.

The utility model only needs kinematic link is changed.Can be widely used in various locksets such as general door lock, padlock, drawer-lock, bag lock.Key is easy to carry, can open many locks in the compass of competency.
