Description

A kind of novel anti-theft door lock

Technical field

This utility model relates to field of lockset, particularly to a kind of novel anti-theft door lock.

Background technology

At present, antitheft door on market is of all kinds, but the moulding of its keyhole is similar, being at the place being less susceptible to touch with hands, when that night goes home to be opened the door, usual keyhole is the most difficult to find, need could quickly open the door during illumination, for the people that some are the most drunk, when go home in the evening, open the door and be difficult to especially.

Utility model content

In order to be able to efficiently solve darkness or drunk time antitheft door the most difficult to find problem of keyhole, this utility model provides a kind of novel anti-theft door lock, and its technical scheme used is as follows:

A kind of novel anti-theft door lock, it is characterized in that: include door-plate, protection board, lower dead bolt group, upper lock tongue, big screw, Screw, lock core, lock body, door handle, keyhole, described protection board is fixed on the side of door-plate by big screw, described upper lock tongue is connected through the top half of protection board with door-plate, described lower dead bolt group is connected through the latter half of protection board with door-plate, described lock body is fixed on door-plate by Screw, the top half of described lock body is machined with lock core, it is machined with keyhole on described lock core, the latter half of described lock body is provided with door handle.

Above-mentioned protection board uses rustless steel to be made, and rustless steel quality is hard, is difficult to get rusty, and wear-resisting, protection board use rustless steel be made can dead bolt group and upper lock tongue under the lowest protection, the abrasion of door-plate can be reduced simultaneously.

The top half of above-mentioned lock core is processed into V-structure, and this structure comparison easily touches, when finding the lock core of V-structure with hands, it is possible to quickly find keyhole, quickly door is opened.

This utility model has the advantage that simple in construction, and cost is relatively low, and operability is relatively strong, applied widely, uses the lock core of V-structure, solve darkness or drunk time, the problem that the keyhole of antitheft door is the most difficult to find.

Accompanying drawing explanation

Fig. 1: overall structure schematic diagram of the present utility model；

Fig. 2: the structural representation of lock core part of the present utility model；

Symbol description:

1. door-plate, 2. protection board, 3. descend dead bolt group, 4. upper lock tongue, 5. big screw, 6. Screw, 7. lock core, 8. lock body, 9. door handle, 10 keyholes.

Detailed description of the invention

With example, this utility model patent is described further below in conjunction with the accompanying drawings:

Such as Fig. 1, shown in Fig. 2, a kind of novel anti-theft door lock of the present utility model, including door-plate 1, protection board 2, lower dead bolt group 3, upper lock tongue 4, big screw 5, Screw 6, lock core 7, lock body 8, door handle 9, keyhole 10, described protection board 2 is fixed on the side of door-plate 1 by big screw 5, described upper lock tongue 4 is connected through the top half of protection board 2 with door-plate 1, described lower dead bolt group 3 is connected through the latter half of protection board 2 with door-plate 1, described lock body 8 is fixed on door-plate 1 by Screw 6, the top half of described lock body 8 is machined with lock core 7, it is machined with keyhole 10 on described lock core 7, the latter half of described lock body 8 is provided with door handle 9.

Preferably protection board 2 uses rustless steel to be made.

The preferably top half of lock core is processed into V-structure.

When darkness or drunken time, if common antitheft door, its keyhole is difficult to find, key is difficult to be properly inserted in keyhole, when using novel anti-theft door lock of the present utility model, it is easy to touch the lock core 7 of V-structure with hands, due to keyhole 10 just on lock core 7, it is easy for finding, it is simple to key inserts keyhole 10, thus smoothly door is quickly opened.
