Description

Pin type lock and key thereof

The utility model is a kind of pin formula tapered end and key.

Known tapered end for example is used in the cabinet lock, the drawer lock, tapered end on the door lock mostly is the cylinder type tapered end, they are generally by the lock core of being with keyhole, lock tube, shell and the shift fork composition that is fixed in the lock core afterbody, can on the lock tube body of lock core keyhole place and correspondence, the pellet shot from a slingshot hole be set and install pellet shot from a slingshot additional and spring, utilizing the pellet shot from a slingshot of the spoon crest pressure zone spring that corresponding on the key pellet shot from a slingshot matched presets to make lock core eliminate the obstruction of pellet shot from a slingshot between lock core and lock tube is able to rotary locking cylinder and opens lockset by shift fork, it is not strong that this traditional locking mechanism is considered to confidentiality always, main cause is that wherein the wearing and tearing of pellet shot from a slingshot and spring mechanical are big, easily aging again, application life is shorter, the key spoon tooth evagination that it was equipped with very easily duplicates imitation.

The purpose of this utility model provides a kind of confidentiality durability and better sells formula tapered end and key.

The utility model is to realize like this, pin formula tapered end and key have the shell of comprising (2), the lock tube (3) of band pin-and-hole (12), the lock core (4) of band pin-and-hole (13) and keyhole (11) and shift fork (8) are at interior tapered end as shown in drawings and key (1), the pin-and-hole (13) of lock core (4) is arranged on the side of lock core keyhole (11), pin-and-hole (13) cross section be the figure of eight before, back diplopore, contiguous keyhole (11) is preceding hole, it is metapore thereafter, metapore communicates with preceding hole and cuts logical through preceding hole and keyhole (11), the back hole sleeve of the corresponding lock core pin-and-hole of lock tube (3) (13) be provided with can be logical with pin-and-hole (13) metapore pipe pin-and-hole (12), pin-and-hole (12) cross section is " 0 " font, having size between lock core pin-and-hole (13) metapore and the lock tube pin-and-hole (12) also can be at pin-and-hole (12 with the vestibule coupling, 13) pin that slides up and down in (15), have size and the preceding hole coupling of pin-and-hole (13) and the step (16) that can in the preceding hole of pin-and-hole (13), slide up and down on the pin (15), step (16) towards the table top of keyhole (11) and adjacent key hole wall in one plane, step (16) central authorities also are connected with a cylindrical step (17), pin (15), step (16) and cylindrical step (17) are formed lock pin (5) as above-mentioned stack successively, described key (1) both sides spoon face is respectively equipped with the curved groove (9) of vallecular cavity size and cylindrical step (17) coupling, the length of spoon tooth height and corresponding each pin coupling in the groove that curved groove (9) forms, and the tooth number of spoon tooth equates with the pin number, like this, when pin spoon (1) when not entering lock core, pin (15) lower end of lock pin (5) is in lock core hole (13) is in lock tube hole (12), rotate in lock tube thereby hinder lock core, tapered end is blocking; And in key (1) inserts lock core (4) keyhole the time, when if the curved groove (9) of key (1) mates with lock pin (5) length respectively as above-mentioned its spoon tooth height, can make the interior lock pin (5) of round with its cylindrical step (17) moving along curved groove (9), and under the supporting role of spoon tooth, make it up and down arrive lock core (4) periphery height simultaneously in pin bottom surface, two ends, thereby lock core (4) is removed obstacles rotated freely in lock tube (3) and open lockset by lock core (4) afterbody shift fork.Extract key (1) once again out, lock pin (5) loses support and falls and insertion lock tube pin-and-hole (12) because of conducting oneself with dignity, tapered end reenters locking states, obviously, it is this that to fall to opening and closing wear-out part lock pin (5) that the locking mechanism of lockset adopted by the pin lifting pin much bigger more than the intensity of the more piece pellet shot from a slingshot of general cylinder lock especially spring, so its durability, reliability has obtained strengthening greatly.Again because the pin spoon (1) that the utility model adopts spoon tooth is recessed showing in the curved groove (9) of spoon sheet, bring suitable difficulty to machining, and the spoon tooth height of every key is that all each is different for the form of curved groove, not having numerical control to wash the very difficult imagination of bed one class high-tech manufacturing process has simpler technology to carry out single-piece and even production in bulk, therefore this in the ordinary course of things tapered end is especially sold the very difficult imitation of spoon or is duplicated individually, and this has just improved its confidentiality widely.

Be described further below in conjunction with accompanying drawing.

Accompanying drawing is depicted as the structural representation of a specific embodiment of the utility model, and wherein 1-sells spoon, 2-shell, the 3-lock tube, 4-lock core, 5-lock pin, the 6-ring segment, the 7-collar, 8-shift fork, the 9-curved groove, 10-cannelure, 11-keyhole, the 12-pin-and-hole, 13-pin-and-hole, 14-pin, the 15-pin, 16-step, 17-cylindrical step.

Pin formula tapered end of the present utility model and key have copper lock core (4), lock core (4) is gone up the copper lock tube of suit (3), lock tube (3) is gone up by one deck iron shell (2) big envelope, one end of the external lockset dead bolt of lock core (4) is that afterbody is by the metal collar (7), pin (14) affixed metal shift fork (8), lock core (4) connects the other end of shift fork (8) one ends for can insert the keyhole (11) of key (1), correspondence is provided with the pin-and-hole (13) that five cross sections of the two every rows of row are the figure of eight on the lock core of keyhole channel both sides, have the every row of 8 rows five holes on lock tube (3) body of respective pin hole (13) metapore and be the per 90 ° of two row's equally distributed pin-and-holes (12) arranged side by side of warp-wise, lock core (4) has and pin-and-hole (12 with lock tube (3), 13) vestibule coupling, the long interior spoon of curved groove (9) tooth with key (1) of its pin just mates, its pin (15) can be in vestibule the lock pin 5 that slides of easy on and off, lock pin 5 is three layers of combination, wherein the changeable stub of length is pin (15), has the pillar step (16) that an energy slides up and down on the pin (15) in lock core pin-and-hole (13), the adjacent wall of the table top of step (16) and keyhole isoplanar, this dovetail groove type structure can prevent laterally shifting out of pin (15), step (16) table top central authorities also are provided with cylindrical step (17), in the present embodiment, the lock pin of these three layers of combinations is processed by a metal material integral body.For prevent that lock core (4) from moving axially in lock tube (3), also be provided with between lock tube (3) and the lock core (4) restriction lock core (4) axial displacement by cannelure (10) and be installed on the stopping means that the interior ring segment (6) of cannelure (10) is formed.After lock pin (5) is inserted in the pin-and-hole of lock tube and lock core, because the big envelope effect of shell (2) and can not leaking outside.The key of this tapered end (1) is the top of the copper dull and stereotyped tip key piece of a slice spoon sheet both sides spoon face that inserts lock core or bottom according to pin (15) size of each five lock pin (5) in two row's pin-and-holes (12, a 13) curved groove of supporting cutting (9) respectively.For convenience of the user, the positive and negative both sides of key can both be used, curved groove corresponding with above-mentioned curved groove of supporting cutting also can be distinguished in bottom or top at spoon sheet both sides spoon face open curve groove, key can arbitrarily be inserted when the user undoes the lock like this and needn't be carefully to keyhole, in case key inserts keyhole, only the key half-twist can need be realized the unlatching of locking.The utility model pin formula tapered end of Gou Chenging and key are truly feasible through sample lock probationary certificate thus, have good confidentiality, characteristics that durability is good, practical and convenient.
