Abstract
The utility model discloses a dead bolt lock preventing from being unlocked by a thin slice. The technical scheme is achieved as follows: the dead bolt lock comprises a bolt and a lock catch. The bolt comprises a bolt body (1), a bolt incline (2) and a groove (3) on the bolt incline (2); and the lock catch comprises a lock catch body (4) and an incline (5) on the lock catch body (4). The dead bolt lock using the bolt and the lock catch can prevent from being unlocked by using the thin slice to force the bolt body (1) to shrink back from a gap (8) between a stile (6) and a door frame (7).
Description
Technical field
The utility model relates to a kind of lockset, especially relates to a kind of pin tumbler lock that prevents with the slice substance unlatching.
Background technology
The lockset that is used for locking a door at present mainly contains spring padlock and the pin tumbler lock two big classes that are loaded on the stile.Owing to use spring padlock cumbersome, thereby most of user uses the pin tumbler lock that is loaded on the stile.The lock body of this pin tumbler lock is installed on the stile, another annex---snap close, and then correspondence is installed on the doorframe, and at closing time, the movable dead bolt on the band inclined-plane in the grille main body inserts in the snap close that is installed on the doorframe, with the purpose that realizes locking a door.Yet this type of lockset can insert slice substance by the slit between stile and the doorframe, forces movable dead bolt to be shunk back from the inclined-plane of dead bolt, and door is opened, and safety is not high.In order to solve this deficiency, the pin tumbler lock that has occurred the band insurance of number of different types on the market again, this class pin tumbler lock has increased dead bolt insurance annex in the main part of lock, key must be inserted lock core when locking a door and be rotated counterclockwise, stir dead bolt insurance annex and prop up dead bolt, just can reach insurance purpose, still bother during use, simultaneously, owing to increased the insurance annex, so cost is higher.
The utility model content
At the above-mentioned defective that exists in the prior art, the utility model provides a kind of simply constructed pin tumbler lock that prevents with the slice substance unlatching.
To achieve these goals, the utility model adopts following scheme: it comprises dead bolt and another annex---snap close.Dead bolt comprises the groove on dead bolt body, dead bolt inclined-plane and the dead bolt inclined-plane; Snap close comprises the inclined-plane on snap close body and the snap close body.When being injected by the slit between stile and the doorframe with slice substance, slice substance falls in the groove, can not force dead bolt to be shunk back door lock is opened.For allowing dead bolt insert smoothly in the snap close at closing time, snap close is designed to the inclined-plane with the position that the dead bolt inclined-plane contacts, this inclined-plane is parallel with the dead bolt inclined-plane, and its width is wideer than the groove on the dead bolt inclined-plane.
After adopting such structure,, thereby when having guaranteed that effectively slice substance inserts crack between a door and its frame, lockset can not be opened because the dead bolt inclined-plane is provided with groove.Again since the snap close body be provided with the inclined-plane, at closing time, can not block snap close because of the groove on the dead bolt, make not flexible of dead bolt, thereby use the same with former lock convenient.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is the dead bolt schematic diagram, wherein, and dead bolt body (1), dead bolt inclined-plane (2), groove (3).
Fig. 2 is the snap close schematic diagram, wherein, and snap close body (4), snap close inclined-plane (5).
Fig. 3 is a pin tumbler lock locking states schematic diagram, wherein, and stile (6), doorframe (7), the slit (8) between stile (6) and the doorframe (7).
The specific embodiment
By Fig. 1 and as can be known shown in Figure 3, the end of dead bolt body (1) is inclined-plane (2), force dead bolt body (1) to be shunk back in order to hinder slice substance by the slit (8) between stile (6) and the doorframe (7), door lock is opened, on dead bolt inclined-plane (2), be provided with groove (3), groove (3) can be one, also can be many.Like this, when being injected by the slit (8) between stile (6) and the doorframe (7) with slice substance, slice substance promptly falls in the groove (3), therefore can not force dead bolt body (1) to be shunk back, thereby reaches the purpose that prevents to open with slice substance door lock.
By as can be known illustrated in figures 1 and 2, at closing time, there is a position to contact on the snap close body (4) with dead bolt inclined-plane (2), seamed edge jacking groove (3) for fear of this position, influence is closed the door, establish an inclined-plane (5) at this position, inclined-plane (5) are parallel to dead bolt inclined-plane (2), and wideer than the groove (3) on dead bolt inclined-plane (2).
Claims (3)
1. the pin tumbler lock that can prevent to open with slice substance comprises dead bolt and snap close, and it is characterized in that: fluted (3) are gone up on the inclined-plane (2) of dead bolt body (1) end; Snap close body (4) has inclined-plane (5) in the part that contacts with described dead bolt inclined-plane (2) earlier at closing time.
2. according to the described pin tumbler lock of claim 1, it is characterized in that: described snap close inclined-plane (5) is parallel to dead bolt inclined-plane (2).
3. according to the described pin tumbler lock of claim 2, it is characterized in that: described snap close inclined-plane (5) is wideer than the groove (3) on dead bolt inclined-plane (2).
