Description

The bilateral auxiliary lock of tool bolt protective cover

The utility model relates to a kind of auxiliary lock, particularly a kind of bilateral auxiliary lock of tool bolt protective cover.

The application of lockset can provide a kind of safety guarantee to the room door, its development so far, progressive gradually from the single lockset in past to the combination of multiple multiple lockset now, auxiliary lock wherein promptly is the lockset that adds again at the original existing door-plate that lockset is set, and can further strengthen the security protection effect of this door-plate, this auxiliary lock can be divided into several following forms substantially, one is that single side use is key operated, another side is closed person, two to be that single side uses key operated for it, another side is revolving twistlock person, its three 70 of bilateral auxiliary locks as shown in Figure 6 are the form that dual-side all can be key operated, wherein, bilateral auxiliary lock 70 includes the combination of locking bolt 71 and interior lockset 72 and outer lockset 73, and can be in door-plate 701, outer both sides are locked with key respectively or are opened, wherein, in, outer lockset 72, form relative shell 721 on 73 respectively, 731, positioning seat 722,732 and the core 723 of form relatively is set wherein, 733, two cores 723,733 utilize double-action plate 74 to pass through locking bolt 71 is linked, and, core 733 medial surfaces are provided with the nose bar 734 that contains inner bolt hole, and the bolt 724 that can penetrate for core 723 end faces by interior lockset 72 is locked.

The form setting of this bilateral auxiliary lock 70, though the person of being easy to use is by in the door, the outside utilizes key to be opened or lock, yet, set bolt 724 on the door-plate 701 inboard interior locksets 72, its bolt head 725 exposes to core 723 end faces, and can be unclamped and the lockset that gets loose through screwdriver, this uses for general house and still is unlikely the too big problem of generation, because, the bolt head 725 that exposes is core 723 end faces of lockset 72 in being arranged at and is positioned within doors, the stranger still can't directly unclamp the fixed of bolt 724 for the outer lockset 73 in door-plate 701 outsides outdoors, and do not have in the occasion that obviously separates if this bilateral auxiliary lock 70 is arranged on the interior outside, then this bilateral auxiliary lock 70 promptly can't provide safety guarantee effectively, because, a side of lockset 10 in the door-plate 701, bolt head 725 on its lock core base 20 is that formation is exposed, and can the people be that the mode that gets loose is unclamped lockset and entered in the opposite side zone of door-plate 701 blocks, moreover, the bolt head 725 that exposes destroys the aesthetic feeling of lockset integral body easily because of corrosion after use for years, therefore, in the use of bilateral now auxiliary lock 70, the shortcoming that still has some deficits and having much room for improvement.

Because traditional bilateral auxiliary lock still has and is easy to suffer that the people is the shortcoming of unclamping exposed bolt head, knowledge and the experience of this creator to be engaged in this industry for many years, design the utility model " the bilateral auxiliary lock of tool bolt protective cover " and study intensively, the front, end of lockset core in it is covered in protective cover, in order to cover the bolt head that exposes, making intentionally, the personage wants that dismantling lockset in the mode of unclamping bolt invades in the door, but can't judge the correct orientation of this bolt head at short notice immediately, reach and prevent that lockset is easy to suffer the people to unclamp and have the aesthetic that uniformity is decorated concurrently.

The purpose of this utility model is: the bilateral auxiliary lock that a kind of tool bolt protective cover is provided; can be with the bolt head of wearing the bolt of lockset and outer lockset in knot locking covering protection in addition; and can prevent people's quick-release bolt unlatching door-plate for it, and the ornamental effect that can form inside and outside lockset end face unanimity is used in the covering of protective cover.

The technical solution of the utility model is to provide a kind of bilateral auxiliary lock of tool bolt protective cover, this bilateral auxiliary lock is by in the bolt polyphone, outer lockset and locking bolt are formed, in, include housing in the outer lockset respectively, positioning seat and lock core base, the combination of core, outer lockset positioning seat bottom face is provided with the nose bar that several contain screw, bolt for lockset in passing is locked, the lock core base front side forms bigger end, circle footpath, the bottom of end and interior lockset rear side is provided with relatively and the hole of running through, bolt passes the hole and passes the set following locating hole of positioning seat bottom face and lock in the nose bar of outer lockset, be provided with locating slot in the lock core base, with the core setting of drawing out type wherein, it is characterized in that:

The positive identical protective cover in end face form and lock core base end can be consolidated in the lock core base end, but forms the protective cover sheathing in the positive form of lock core base end, and the bolt head that will wear the bolt of knot is covered.

In the bilateral auxiliary lock of above-mentioned tool bolt protective cover, the end periphery of lock core base can be provided with slot, protective cover is provided with and the consistent lock core hole of lock core base locating slot open end, the protective cover peripheral side is to extending the flange ring, flange ring leading edge is provided with the little curved lug that radially bends, the lug of protective cover can be sheathed on lock core base end periphery, but and little curved lug clip in slot.

The utility model compared with the prior art advantage and good effect is very obvious.By above technical scheme as can be known, protective cover of the present utility model, it can form the security protection of covering for the bolt head of bilateral auxiliary lock, and can prevent that illegal people from being unclamped for the bolt of lockset easily, invade and not to be allowed to the door-plate that enters side zone in addition, and, it has the effect of decoration concurrently, and can make and form the both ends of the surface of bilateral auxiliary lock complete uniformity, and prevent that the bolt head that exposes is easy to the effect of oxidation corrosion.

Further specify specific structural features of the present utility model and purpose below in conjunction with accompanying drawing.
