Abstract

The utility model relates to an anti-prying and theftproof lock button, which is made of metallic plate. The utility model is characterized in that at least a lock button beam is arranged in the lock button, the lock button beam is at least provided with a hole passing through a lock beam, and the lock button beam is confined in a semi-enclosed shell. Because the lock button is in a semi-closed state, and increases an arch anti-prying pad in the lock button, and a rainproof cover plate above the shell of the lock button, the lock button has the advantages of anti-prying function, theftproof function, rainproof function, sunscreen function, and simple structure. The utility model is especially suitable for various outdoor doors and windows.

Description

Locking button

The utility model relates to a kind of snap close, particularly a kind of can pick-proof, antitheft snap close.

At present, the dark formula door lock of the general employing of the domestic lockset that is used for locking a door, loose-leaf button nose adds padlock, and inserting bolt type bolt bar adds padlock.The two kinds of lockset large usage quantities in back, though dark formula door lock has certain tamper-resistant function, but its accommodation is narrow, especially can not be applicable to double door, thereby the scope of application is subjected to certain restriction, and loose-leaf button nose adds padlock, inserting bolt type bolt bar adds padlock, though simple in structure, they do not possess tamper-resistant function, this has just had opportunity to the lawless person.

The purpose of this utility model provides a kind of novel snap close, cooperate padlock can realize pick-proof, anti-theft feature, and technology is simple, and the life-span is long, the snap close that the scope of application is wide.

The purpose of this utility model is achieved in that

A kind of snap close of making by metal sheet, form by snap close beam, U-shape lock button nose, it is characterized in that described snap close beam has one at least, have the hole that can pass lock bridge on each snap close beam at least, the snap close beam has been closed in the semiclosed housing of pick-proof, antitheft effect.Housing can be dustpan shape.More reliable for the pick-proof, the anti-theft feature that make snap close, the place at corresponding crack between a door and its frame place has increased by a pick-proof buting iron by welding on snap close beam bottom.On snap close beam topmost, increase an arch pick-proof pad by welding.The snap close nose is designed to the shape that side direction is the U type in the utility model.

The purpose of this utility model is that also snap close has a snap close beam at least, also can have the snap close beam more than two.Have the hole that to pass lock bridge on each snap close beam at least,, on every snap close beam of this snap close two holes that can pass lock bridge are arranged for adapting to the situation of existing padlock in the market.The snap close outward appearance is semi-closed state.Above semi-enclosed housing, have one can be by lock bridge the flat hole, in order to prevent the wind and rain Exposure to Sunlight, above housing the place's design and installation of flat hole a movably rainproof cover plate.

The utility model compared with prior art has following advantage:

1. the utility model is owing to used semienclosed snap close, and snap close and snap close nose all adopt the right-angle type face to combine with door or window by dress, there is logical heart bolton in the front, the side has four screws to replenish reinforcing, sealed back outward appearance is semi-closed state in the use, open the lock with the key except making, any instrument all can not be pried open, thereby has pick-proof, anti-theft feature.

2. because the utility model latches on the semi-enclosed basis of outward appearance, and housing top also is added with rainproof cover plate, thereby be specially adapted to occasion such as outdoor door and window and use, it can protect internal lock not attacked by wind and rain effectively, increases the service life.

3. this lockset can be made into different size, can be widely used in double door, the single open-door that door leaf flushes with doorframe, occasions such as iron gate.

Embodiment 1:

Two type snap close beams, dustpan shell body, arch form pick-proof pad, being certain thickness metal sheet (this routine thickness is the metal sheet of 3.5mm) forms by punch forming, two type snap close beams, dustpan shell body, arch form pick-proof pad, by the structure that is welded as a whole, the effect of arch form pick-proof pad is: (1) lock bridge location; (2) person that prevents the picking lock utilizes instrument to insert and upwards levers up lock bridge below the lock bridge.On the two type snap close beams be two groups of four slightly larger in diameter in the hole of n type lock bridge diameter, its center range distribution and n type lock bridge two straight flange concentrics.Be two holes on same axle center on the U-shape lock button nose, bore dia is slightly larger than the diameter in hole on the two type snap close beams.Purpose is to allow the user to install and has certain deviation range, and the center in two holes on the U-shape lock button nose is consistent with the center of corresponding aperture on the two type snap close beams.Split type padlock, free gap in semi-enclosed snap close is average every limit 1.5-2mm, can guarantee that like this user's locking and unlocking is convenient freely, person's insertion instrument destroys to prevent the picking lock again, alignment pin (7) is a garden type head for auxiliary accessories one end, one end is the riveted joint body, and it is applicable on the double door and installs and uses.Also can, make by oneself by the user, wherein split type padlock uses the bicycle lock of selling in the market that the utility model snap close requires that meets, just n type lock bridge is a specific dimensions, can be supporting by producer.After unblanking, the separated attitude of n type lock bridge and lock body, when using this snap close nose, to close neat earlier by the door and window that installs the snap close nose, remove rainproof cover plate, n type lock bridge is inserted downwards in the hole on the snap close by the flat hole of housing top, and pass hole on the U-shape lock button nose, again lock body is aimed at center, snap close housing below up and upwards slippaged, lock can be locked.During unlatching, key is inserted in the keyhole on the lock body, screw key ejects lock bridge from lock body, take out lock body downwards, upwards transfers to lock bridge.

Embodiment 2:

Be provided with the rainproof cover plate of a rectangle with embodiment 1 different being above the described housing, can move freely, when sealed, earlier rainproof cover plate is removed, insert lock bridge downwards.After sealed, move rainproof cover plate, cover the flat hole, its main purpose is for the padlock in the housing is carried out rainproof, preventing coating protection.
