The utility model has the advantages of unique structure, reasonable design, low mutually unlocking rate and high anti-theft performance, and the key has unique function of not being copied and can be matched with locks in various structures; the utility model is beautiful, can be used for a long time and relates to a good lock which can be widely applied.

Description

Two-sided asymmetric hoodle U-lag tapered end

A kind of two-sided asymmetric hoodle U-lag tapered end is door lock series parts in the architectural hardware industry, can with the supporting uses of multiple high-grade door lock such as general rim lock, electric control door lock, locking.

Commercially available its tapered end flute profile of door lock is essentially F shape at present, and S shape, in-line and cross etc. only simultaneously have hoodle in F shape and the S shape lock core, and its reasonable tooth number is limited, and causes the mutual opening rate height.Be respectively two sides hoodle and four sides hoodle in in-line and the cross tapered end, the tartar number of combinations is a lot, but because of its Round nose sub level difference is too little, so mutual opening rate is equally very high.

The purpose of this utility model provides a kind of two-sided asymmetric hoodle U-lag tapered end, to overcome the commercially available high disadvantage of door lock mutual opening rate at present, improves theftproof performance.

Purpose of design of the present utility model is to solve the high problem of door lock mutual opening rate.Its design is such: at first be to solve reasonable tartar number of combinations problem.The utility model adopts two-sided asymmetric hoodle, and hoodle (cylinder pearl) number is increased to nine by five in the general tapered end, and its tartar number of combinations increases greatly.Secondly need to solve the differential problem of hoodle in in-line and the cross tapered end.The key of two-sided asymmetric hoodle U-lag tapered end adopts wide spoon base, key both sides tartar height is asymmetric, and the also corresponding increasing of lock core and lock housing external diameter has so just guaranteed the differential of hoodle, thereby solved because of differential too little cause open disadvantage mutually, greatly reduce mutual opening rate.In reality processing, open the U-lag of band both wings vertically at the middle part of tapered end lock core, shape be disposed radially six section of nine row's hoodle at the position of both wings, and two sides hoodle height is asymmetric as " U-".U-shaped key with a kind of two-sided asymmetric tartar mates two-sided asymmetric hoodle U-lag tapered end, and its number of combinations can reach more than 5,000,000 clocks, and mutual opening rate is lower than 4,000,000/, therefore, can reach goal of the invention of the present utility model.

The novel advantage of this use is tangible: one, and it has ultralow mutual opening rate, the high security energy.Its tapered end adopts six section of nine pearl structure, and its reasonable tartar number of combinations increases greatly.The tooth number that national standard requires is 6000 kinds, mutual opening rate＜0.204%, and the reasonable tartar number of combinations of two-sided asymmetric hoodle U-lag tapered end can reach more than 5,000,000 kinds, mutual opening rate is lower than 4,000,000/and, the highest mutual opening rate that allows well below national standard.Two, exclusive anti-copy function.The key of the utility model coupling has unique spoon base width, grooved and two-sided asymmetric tartar.Do not have at present identical spoon base on the market, general Bitting machine also can't duplicate two-sided asymmetric tooth-engraved key, has only with special tartar cutting machine and could make.Three, can with the supporting use of multiple structure door lock.It can with the supporting uses of multiple high-grade door lock such as plain edition rim lock, electric control lock and locking, elegant in appearance, durable in use.

Further set forth structure of the present utility model below with reference to the accompanying drawings.Accompanying drawing 1 is the utility model part sectional structure sketch.Accompanying drawing 2 is the utility model front view.Accompanying drawing 3 is looked sectional view for the utility model right side.Accompanying drawing 4 is the utility model parts key front view.

We learn with reference to the accompanying drawings: two-sided asymmetric hoodle U-lag tapered end, mainly form by tapered end 1, lock core 2 and key 3, its design feature is the U-lag hole 4 that lock core 2 middle parts have a band double-vane vertically, the 4 both sides arranged radiallys of double-vane U-lag hole have asymmetric cylinder hoodle 5, and key 3 both sides tartars 6 are highly asymmetric.Its second design feature is that double-vane U-lag hole 4 can be an arc-shaped hole, also can be slot.Its 3rd design feature is that the cylinder hoodle 5 of double-vane U-lag hole 4 both sides arranged radiallys is 5～12 rows (pearl).

The single face locking cam theftproof performance of being sold on the market at present is poor, and the common spring lock is also pushed aside by the robber easily.And the two-sided asymmetric hoodle U-lag tapered end mutual opening rate of certain company is extremely low, and theftproof performance is splendid.The utility model can assemble multiple high-grade door locks such as common rim lock, electric control door lock, locking.Its tapered end shell, lock core are all made with the high-quality copper material, and be elegant in appearance, durable in use, is that the lock kind that adopts is liked by numerous residents and enterprise and institution.
