Abstract

The utility model relates to an anti-prizing cool proof door lock, which is composed of an existing padlock, the lock catch is equipped with an anti-prizing block slice, and a cool proof sleeve which on the outer lateral surface of the lock body. The anti-prizing block slice comprises a negative and a standing slice which is perpendicular to the negative. The shape and size of the negative is the same with the shape and size of the upper end face of the lock body; the shape and size of the standing slice is the same with the shape and size of the lock catch ring hole. The door lock has the characteristics of rational design, simple structure, safe and applied.

Description

The pick-proof coolproof door lock

The utility model belongs to a kind of door lock, is to be furnished with few parts to combine on existing padlock.

Door lock is the anti-theft tool of many places indispensabilities such as family, office, storehouse, factory building and market, built-in lock and padlock are arranged, built-in lock is the inboard that is contained in door, be used for family and office, but the dead bolt of built-in lock is shorter more, intensity is also lower, to the Men Eryan of general structure, when being subjected to clashing into, easily the generator gate body deformability is forced open the door, what also have also can open the door sometimes from prizing group dead bolt outdoors, and safety is relatively poor; Padlock is on the door nose that is locked in outdoors, be used for storehouse, factory building, the antitheft place of market emphasis more, but since padlock be exposed outside, when north cold area opens the door winter, because of the ice-cold and sticking hand of lock body, simultaneously ironware also easily inserts in the snap close annular distance and forces open the door and press lock, and theftproof is relatively poor, for addressing this problem, just on the door nose, baffle plate is installed with front end, but this door nose is outwards outstanding bigger, not attractive in appearance, and it is all inconvenient to lock a door and open the door.

To be that design is a kind of install few parts additional to the purpose of this utility model on existing padlock, is combined into safe and practical, easy to operate pick-proof coolproof door lock.

The utility model pick-proof coolproof door lock is made up of lock body and snap close, it is characterized in that being equipped with on snap close the pick-proof jam; Be with every the cold cover in the side of lock body.

The pick-proof jam is formed by egative film with perpendicular to the upright sheet of egative film.

The shape of egative film size is the same substantially with lock body upper surface shape size, respectively opens a circular hole that is slightly larger than the snap close diameter in the position of close egative film two ends, corresponding snap close, founds sheet and be vertically fixed between two circular holes of egative film; The shape size of upright sheet and the shape size of snap close annular distance are consistent, have the breach of inserting door nose in upright sheet upper center.

The pick-proof jam is to make of the metal sheet that certain intensity is arranged, the thick 1.5--5mm that is generally of egative film, the upright thick 3--8mm that is generally of sheet.

Can make also available plastic production of rubber every the cold cover.

The utility model and existing padlock relatively have following advantage:

Owing to be on the snap close of existing padlock, the pick-proof jam to be housed, be with every the cold cover at the lock body lateral surface, so can prevent to insert the problem of the pressure lock of forcing open the door in the snap close annular distance with ironware, also solved the problem that the lock body that opens the door winter freezes hand, utilize existence conditions to install suitable parts additional and obtain pick-proof, have simple in structure, safe and practical, flexible operation and advantage such as cheap every cool effect.

Fig. 1 is the structural representation of pick-proof coolproof door lock;

Fig. 2 is the structural representation of pick-proof jam;

Fig. 3 is the vertical view of Fig. 2;

Snap close 1 is arranged among the figure, and the lock body side overlaps 2 every cold, door nose 3, egative film 4, upright sheet 5, breach 6, key 7, circular hole 8.

For an embodiment, and the accompanying drawings using method:

According to above-mentioned design scheme, the inventor has manufactured experimently a pick-proof coolproof door lock with oneself padlock, snap close diameter phi 5mm, the pick-proof jam is made of iron plate, and two Circularhole diameters that egative film is worn snap close are φ 5.5mm, the thick 2mm of egative film, the upright thick 6mm of sheet applies mechanically rubber every cold and makes.The pick-proof coolproof door lock that assembles, two circular holes all are enclosed within on the snap close, when locking a door on the egative film of pick-proof jam, earlier the circular hole on the egative film is taken off from the openend of snap close, again snap close is inserted the door nose, and then snap close is inserted in the circular hole of having taken off on the egative film, lock the door.Prove that through practicality pick-proof is respond well every cold, easy to operate.
