Abstract

The utility model belongs to the manufacturing technology of hardware locks and relates to a double-row marble full-moon lock. The bits of an original double-row sash lock are drilled into bit through holes, a long marble is added, and the height of the long marble is the height from the surface of a lock cylinder to the bottom of a key hole, so as to achieve such an effect that when a person pries up the lock cylinder through a steel wire, the long marble is jacked up and is crossed on the interface of the lock cylinder and a lock head, the lock cylinder is locked, and the lock head cannot open. The full-moon lock has the advantages of novel design, reasonable structure, low production cost and good prying prevention effect. The double-row marble full-moon lock comprises the lock head (1), the lock cylinder (2), double-row full-moon key holes (3), lock cylinder marble holes (4), lock cylinder marbles (5), and double-row bits (8) on a key body (7) of a double-row full-moon key (6), and is characterized in that the bit through holes (9) are formed in the double-row bits (8).

Description

The double pellet shot from a slingshot moon is justified lock

Technical field:

The utility model is a kind of tapered end commonly used, and particularly a kind of double pellet shot from a slingshot moon is justified lock, belongs to five metals lockset manufacturing technology.

Background technology:

Double crescent lock is the very general tapered end of a kind of use, and the one side of its key is a circular arc, and another side has the double tartar perpendicular to horizontal plane, and so the keyhole form crescent moon on its lock core is the double crescent lock of called after.It uses wide, and its cost of production is low, and making convenient is its advantage.But this kind tapered end still has its weakness.It has only three kinds of hoodles in lock core, i.e. 1,2, No. 3 hoodle, hoodle length is respectively 5.2,6.0 and 6.8 millimeters, depth of threat on the key is respectively 0.2,1.0,1.8 millimeter, the differential of three kinds of hoodles is 0.8 millimeter, have only when the differential 0.7-0.8 of reaching millimeter, the mutual opening rate of its tapered end is just guaranteed.Calculate by 8 effective hoodles, 6561 spoon yardages should be arranged in theory.But do not reach this theoretical value in the actual production.Its weakness is constantly to instigate probably at lock core external application steel wire tapered end is opened, and its theftproof performance is relatively poor, and its operative norm can only reach the QB/T2474-2000B grade standard.Therefore, this common spring tapered end has improved necessity.The utility model applicant works in the lockmaking industry for a long time, has accumulated more rich lockmaking experience, and he improves traditional double crescent lock audaciously, succeeds finally.This is the background that the utility model produces.

The utility model content:

The purpose of this utility model provides round lock of a kind of double pellet shot from a slingshot moon, it is to improve on former double pellet shot from a slingshot crescent lock, the Drilling that the tartar of the key of former double crescent lock is had becomes the tartar through hole, and former three kinds of hoodles are increased a kind of long hoodle, the height of this long hoodle is the height of plug face to the keyhole bottom surface.Thereby reach such effect, when the people of its theft stirred lock core marble at lock core external application steel wire, this long hoodle must be entered in the tapered end from lock core by jack-up, and lock core can not be opened by locking, has increased its theftproof.Therefore, the utility model modern design, rational in infrastructure, easy to manufacture, cost of production is low, anti-to dial performance good for pick-proof.The technical scheme of the utility model technical solution problem is such: inventor's design, improve the anti-performance of dialling of pick-proof of traditional double pellet shot from a slingshot crescent lock, its basic point is that an obstacle is set in lock core, reach you and prize and stir pellet shot from a slingshot outside, and pellet shot from a slingshot is lived the lock core locking on the contrary, can not unblank.The utility model comprises tapered end, lock core, double month circle keyhole, lock core marble hole and lock core marble, and at the spoon of double month circle spoon double tartar, its first design feature being arranged on one's body is that the tartar through hole is arranged in double tartar; Its second design feature is that 1 to 4 tartar through hole is arranged in double tartar; In tapered end, assemble lock core, at lock core marble hole assembling lock core marble; Front end at lock core has double month circle keyhole, and the one side of the spoon body of double month circle spoon is a circular arc.In sum, the utility model has the advantages that significantly:＜one novel in design, rational in infrastructure, easy to manufacture, cost of production is low;＜two〉greatly improved theftproof, light is stirred tapered end with steel wire, and lock can not be opened;＜three〉extremely low thereby greatly improved its spoon yardage realization mutual opening rate, make the theftproof performance of product improve a new grade.

Description of drawings:

Further understand structure of the present utility model below in conjunction with the description of drawings and the specific embodiment.

Accompanying drawing 1 is the front view of the double crescent moon spoon of parts of the present utility model;

Accompanying drawing 2 is the left view of analysing and observe of accompanying drawing 1;

Accompanying drawing 4 is the upward view of accompanying drawing 1;

Accompanying drawing 5 is a parts tapered end sectional plan view of the present utility model;

Accompanying drawing 6 is the upward view of accompanying drawing 5;

In the accompanying drawing, 1, tapered end, 2, lock core, 3, double month circle keyhole, 4, lock core marble hole, 5, lock core marble, 6, double month circle spoon, 7, the spoon body, 8, double tartar, 9, the tartar through hole.

The specific embodiment:

Make each component of the present utility model with reference to the accompanying drawings, and assemble.Here the of paramount importance inventor's of being innovative point is to add a new hoodle in the lock core hoodle of the original double crescent lock of traditional product.Be that double month circle lock has four kinds of hoodles 1,2,3, No. 4, pearl is long to be respectively: 5.2,6.0,6.8 and 7.6 millimeters.Here 7.6 millimeters is the lock core periphery to the height of keyhole bottom.Depth of threat on the key is respectively: 0.2,1.0,1.8 and 2.6 millimeters, the thickness of key is 2.6 millimeters, and therefore, every correspondence tartar place on the key of assembling No. 4 hoodles on lock core is all worn by Drilling, become tartar through hole 9, this is an innovative point of the present utility model.The utility model has two progressive points like this:＜one〉be when having human steel wire sled to dial lock core, on No. 4 hoodles in the lock core will be arrived interface between tapered end and the lock core by jack-up, tapered end and lock core were blocked by No. 4 hoodles like this, can not rotate, tapered end has been strengthened its theftproof promptly by locking;＜two〉be 1,2,3 and No. 4 four kinds of hoodle, it is differential to be 0.8 millimeter, calculates by 8 effective hoodles, will reach 65536 spoon yardages in theory, and the double crescent lock that its spoon sign indicating number Capacity Ratio is traditional has increased by 10 times, can reach the super B grade standard of QB/T2474-2000.Innovation of the present utility model has like this realized that mutual opening rate is extremely low the anti-function of dialling of good pick-proof again, makes the theftproof performance of product improve a grade.Concrete way is on the spoon body 7 on the double month circle spoon 6 double tartar 8 being arranged, every row 4-5, being total to 8-10 tartar.Any No. 3 tartar 8 Drillings wherein can be penetrated, become tartar through hole 9, become tartar No. 4.We can Drilling 1 to a plurality of tartar through holes, and in actual use,, enough reached its theftproof performance generally with regard to Drilling 1-2.2 groups of 1,2,3, No. 4 pellets shot from a slingshot of 4 li assemblings of lock core marble hole 2 li of lock cores wherein have 2 to be No. 4 pellets shot from a slingshot.So just finished our fittage.Other work are prior art, have not here just narrated one by one.
