Description

The anti-theft door cipher lock linkage

Technical field

The utility model relates to a kind of coded lock linkage, particularly a kind of anti-theft door cipher lock linkage.

Background technology

In order to prevent the loss of country and personal property better, Modern Family and office's major part all are equipped with security door, that have even simple password hole sealing device also is housed at the lockhole of security door, however, but still have some security doors not have antitheft effect, theftproof lock is happened occasionally by the phenomenon that the stranger opens, and does not only have antitheft effect, and has caused certain property loss.

The utility model content

The purpose of this utility model will overcome above-mentioned shortcoming exactly, and a kind of novel structure, ingenious, the easy to operate anti-theft door cipher lock linkage of simplicity of design are provided.

For achieving the above object, the utility model adopts technical scheme as described below: the anti-theft door cipher lock linkage comprises coded lock, connector and multifunctional safety lock three parts.Coded lock is made up of rotary screw, fixture, a retainer ring and three loose collars.The outer periphery of rotary screw is carved with scale, and it is one boring to fix last loose collar that tip has, and rotary screw inserts among the fixture, and freely rotates therein.Fixture is screwed on security door by security door, there is a fixedly scale its outside, in order to determine to open password, be placed with a retainer ring and two loose collars on the innermost layer ring-shaped step of fixture, stop washer all is housed between retainer ring and the loose collar, a keyway is carved with in the innermost layer of fixture, in order to place retainer ring and stop washer.The outside of retainer ring and loose collar all has the identical gap of shape, all also be fixedly connected with flat recess flush end holding screw backing pin without a head on three loose collars, backing pin on each loose collar can be one, also can be two, according to pairing fixedly scale on the residing position of backing pin on the loose collar and retainer ring gap and the fixture, can calculate the password that a cover comprises 6 figure places.Connector is the link between coded lock and the safety lock, and an end of connector can place the gap of coded lock retainer ring and loose collar, and the other end is connected on the multifunctional safety lock of security door, and overhead is on the safety plug of safety lock.Multifunctional safety lock is the general common multifunctional safety lock that security door is installed.

During use, the security door safety lock is locked, connector has just left the gap of coded lock thereupon, and the rotary screw with coded lock rotates several circles then, has just played the cryptoguard effect.When opening security door, respectively by clockwise and rotate counterclockwise rotary screw, corresponding corresponding password, the gap of three loose collars and retainer ring aligns mutually and is on the same axis, and just can make that connecting rod enters in the gap this moment, and safety lock can be opened.

Adopt the utility model of said structure simple and reasonable for structure, easy to operate, anti-theft effect is remarkable, is a kind of simple and practical anti-theft door cipher lock linkage.

Below in conjunction with accompanying drawing the utility model is described in detail.

The specific embodiment

With reference to Fig. 1.The anti-theft door cipher lock linkage comprises coded lock 1, connecting rod 2 and multifunctional safety lock 3.Coded lock 1 is independently parts, and it is fixed on the security door, and coupling bar 2 is the links that connect coded lock 1 and multifunctional safety lock 3, it is fixed on the security door, and can about move freely, multifunctional safety lock 3 is general security door safety lock, it is fixed on the security door.

With reference to Fig. 2.Anti-theft door cipher lock 2 is independently parts, and it comprises rotary screw 4, fixture 5, retainer ring 6, first loose collar 7, second loose collar 8, the 3rd loose collar 9, stop washer 10 and fixing threaded hole 11.Three screw of fixture 5 usefulness are installed on the security door, one fixing scale is arranged on the panel, there are two annular table the inside, be placed with retainer ring 6, two 7,8 and three stop washers 10 of loose collar on the annular table, and on annular table, have a locking groove, in order to place retainer ring and stop washer.Rotary screw 4 inserts among the fixture 5, and rotates freely therein, is carved with 80 scales around the front panel, and end has a fixing threaded hole 11, in order to fixed placement the 3rd loose collar 9 thereon.

With reference to Fig. 2 and Fig. 3.One fixing scale is arranged on the front panel of fixture 5, three fixing threaded holes 14 are arranged simultaneously, fixing threaded hole 14 is fixedly mounted on fixture 5 on the security door, has a locking groove 15 on the annular table of fixture 5 afterbodys, in order to fixedly retainer ring 6 and stop washer 10.

With reference to Fig. 2 and Fig. 4.The outside of retainer ring 6 has a gap 13, and there is a retainingf key 12 inboard, and retainer ring is installed on the interior annular table of fixture 5.
