Description

Novel mechanical

Technical field

The utility model relates to a kind of novel mechanical, belongs to the field of lockset.

Background technology

General in the market lockset is divided into two classes basically: a class is traditional cylinder lock, and second class is a magnetic padlock.Though the variation of having nothing in common with each other in appearance all is that the lock core that can rotate is installed in lock body on its structure, is drilled with several holes on the cylindrical of lock core, pellet shot from a slingshot that setting height(from bottom) is different in the hole and spring make lock core not rotate under the effect of spring.Utilize on the key that groove cooperates change with the height of pellet shot from a slingshot, reach the rotation of lock core, finish the unlatching work of lockset.The cylinder lock set of this structure because pellet shot from a slingshot is not hidden, is easy to be utilized that feel such as surveys, touches, stirs at method and illegal unlatching is a single-row billiard owing to its structure more, so its size of key is very low, mutual opening rate is higher relatively.The structure and the cylinder lock of magnetic padlock are basic identical, just at lock core be separately installed with magnetic bullet on the key, utilize the principle of the mutual repulsion of the N utmost point or the S utmost point to reach the work of rotational lock core, finish the opening process of lockset.Its shortcoming is: the inefficacy of very easily demagnetizing when magnetic marble and key chance heat (greater than 180 ℃).Magnetic bullet is met humidity and is very easily got rusty, and can not normally open lockset, and its size of key is low, easily opens mutually.

Summary of the invention

The purpose of this utility model is to provide a kind of novel mechanical lockset Mi Yin amount bigger, is difficult to pry open with existing method, has effect antitheft, pick-proof.

The structure of novel mechanical is that an overcoat (5) and lock tooth (9) are installed in the lock body (13), lock core (9) has annular pellet shot from a slingshot slideway and centre bore, pellet shot from a slingshot (4) and spring (6) are housed in the hole, little stifled (3) are housed in the centre bore, spring (6) is sleeved on ejector pin (8) above the left part, pushing block (11) is contained in the lock core (9), the groove of ejector pin (8) right-hand member and pushing block (11) aligns, stirring pawl (12) is contained in above the lock core (9), with jump ring (10) lock core (9) is located, cover (2) is fixed on above the lock body (13), and pellet shot from a slingshot (4) is by spring (7) left end roof pressure, and the spring right-hand member contacts with the lock core end face.

The advantage of novel mechanical is that size of key is big, and pellet shot from a slingshot is installed more hidden difficult unlatching, has the function of anti-theft pick-proof, the pellet shot from a slingshot shape can be a convex shape, also can be concave shape, and its lock core can change in the overcoat inward turning, also can rotate in annular groove, trajectory quantity can be 3---6.

The A-A sectional view of Fig. 4 Fig. 1

The B-B portion view of Fig. 5 Fig. 1

By Fig. 1,3,4,5 a fixing overcoat that has n groove (5) and a lock core that can rotate (9) are installed in lock body (13), this lock core processes several annulars uniform pellet shot from a slingshot slideway and centre bore (), install respectively little stifled (3) are housed in n pellet shot from a slingshot (4) (Fig. 1 is expressed as 4 pellets shot from a slingshot) and spring (6) centre bores (), spring (6) is sleeved on ejector pin (8) above the left part, pushing block (11) is contained in the lock core (9), and the groove () of ejector pin (8) right-hand member and pushing block (11) aligns.Stir pawl (12) and be contained in the top jump ring (10) of using of lock core (9) with lock core (9) location, cover (2) is fixed on the lock body (13), and pellet shot from a slingshot (4) is by spring (7) left end roof pressure, and spring (7) right-hand member contacts with lock core (9) end face.

Be processed with the identical n of 5 pellets shot from a slingshot rectangle tooth (14) by Fig. 2 key (1) end, but thickness has nothing in common with each other (one of them thick tooth is positioning tooth (15)), the tooth of the different Mi Yin amounts of length promotes pellet shot from a slingshot (4), moves axially L length.

The specific embodiment

The course of work: key (1) end is processed with the n identical with pellet shot from a slingshot rectangle tooth, thickness difference (wherein a thick tooth is a positioning tooth), the tooth (Fig. 2) of the different size of keys of length promotes pellet shot from a slingshot (4) simultaneously and moves axially L length, middle little stifled (3) promote spring (7) and ejector pin (8) is shifted in the groove of stirring pawl (12) pushing block (11), and key this moment (1) can be finished the rotation of lock core.Stir pawl (12) rotation, stir the component of lockset, finish the unlatching work (Fig. 4,5) of lockset.The change in length of the size of key index of lock core (9) and trajectory groove number and pellet shot from a slingshot (4) has confidential relation.

The design formulas of size of key: ${\left(\frac{l}{l_1}\right)}^n$

In the formula: l-pellet shot from a slingshot length

l ₁-pellet shot from a slingshot length is differential

N-trajectory groove number

For example: when trajectory n was 5, the pellet shot from a slingshot length l was 12mm, the differential l of the design of pellet shot from a slingshot ₁Be 0.5mm ${\left(\frac{l}{l_1}\right)}^n={\left(\frac{12}{0.5}\right)}^3={24}^3$

Size of key=7,962,624

By following formula as seen, the length l of pellet shot from a slingshot is big more, and pellet shot from a slingshot length is differential more little, and it is many more that the trajectory groove is counted n, and its size of key is also big more.This mechanical lock has extremely strong anti-technical opening function, because the work of pellet shot from a slingshot is differential is hidden in the inboard of pellet shot from a slingshot (4) near lock body (13), utilize existing technical opening method, be to be difficult to be felt, visit, touch, toggle it to the differential position of pellet shot from a slingshot by feel, pellet shot from a slingshot is slided up and down in trajectory, and the differential groove of several pellets shot from a slingshot can not be pushed simultaneously the plane of a rotation, and reach the purpose of unlatching.
