Abstract

The utility model relates to a structure for preventing a lock from being pulled out from outside abnormally, which is composed of a lock head (1), a lock head fixing sheet (2), a lock head sleeve tube (3), an anti-drilling reinforcing steel plate (4) and a lock seat bracket (6). The utility model is characterized in that the outer side of the lock head fixing sheet (2) is connected with an anti-pulling sheet (3), so that the utility model has the advantages of simple and reliable structure and easy fabrication and processing without changing the structure of a commercial lock. The utility model is especially suitable for anti-theft doors and rolling doors of families, offices, storehouses, etc.

Description

Lockset is prevented drawer structure

The utility model relates to a kind of anti-drawer structure, the anti-drawer structure of lockset on particularly a kind of security door rolling-gate.

At present, China Totally-enclosed anti-theft gate manufacturer is except that adopting theft-preventing mechanical lock, most a kind of " world lock " (being coil brake lock etc. again) of also having adopted rolling-gate often to use, when this lockset is installed, adopted identical with the tapered end diameter or big slightly hole to fix the support tapered end mostly, owing to be subjected to the restriction of lockset self tapered end draw bail, add the raising of robber's crime means, cause the robber to use the special instrument of pulling out of leaning in the time that is no more than one fen kind, tapered end to be separated with lock body, thereby quiet ground is easily in the inlet chamber.

The purpose of this utility model is exactly to provide a kind of commodity lockset that needn't change can stop lockset to be pulled out the structure of destruction easily to greatest extent, and the anti-security performance of drawing of security door rolling-gate etc. is significantly improved.

The purpose of this utility model is to realize like this, a kind of lockset is prevented drawer structure, forms by anti-drilling reinforcement steel plate (1), lock (2), lock support (3), it is characterized in that being fixedly welded on the tapered end outer end outside the described lock support (3) and the anti-arm-tie (4) that contacts.

An optimum implementation of the present utility model be anti-arm-tie (4) simultaneously for have on anti-drilling reinforcement steel plate (1), the anti-arm-tie one concentric but the aperture is significantly less than the hole of tapered end diameter with tapered end, this hole only can make the key insertion.

The utility model has the following advantages compared with prior art:

1, because the tapered end outside has connected anti-arm-tie, make whole tapered end except keyhole, remaining is all covered by anti-arm-tie, so tapered end can not be pulled away from lock body.

2, the utility model is simple in structure, implements not change the structure of commodity lockset easily, and cost is low.

Accompanying drawing and drawing explanation

Figure is the utility model concrete structure schematic diagram.

(1) anti-drilling reinforcement steel plate (2) lock (3) lock support

(4) anti-arm-tie (5) lock fixed head

Embodiment:

The lock assembly is made up of anti-arm-tie (4), lock support (3), lock fixed head (5), and anti-arm-tie (4) upper punch that wherein 4mm is thick is made the keyhole of ￠ 15mm; The hole (￠ 30mm) that adapts with the tapered end diameter and 4 flange holes of pin (2) are gone out in the centre of lock fixed head (5).After will locking fixed head (5) both sides welding lock supports (3) and make lock (2) installation fastening by the tapered end height, the tapered end outer face is concordant with lock support (3), and it is concentric and lock support (3) and anti-arm-tie (4) is integrally welded with ￠ 30 holes on the lock fixed head (5) that anti-arm-tie (4) (being anti-drilling reinforcement steel plate) is gone up ￠ 15 holes.Be welded between security door door skin and the back veneer.Hole on the anti-arm-tie of Kong Yingyu on the door skin aligns, and during by dress, lock (2) is inserted tapered end in lock fixed head (5) interstitial hole by the door leaf the inside, with screw will lock (2) fastening.On lock fixed head (5).If during the illegal drawing lock of robber's tool using (2), because of anti-arm-tie (4) stops in the outside of tapered end, group's tapered end can not pulled from lock body because of without hindrance block material again.

Claims

1, the anti-drawer structure of a kind of lockset is made up of anti-drilling reinforcement steel plate (1), lock (2), lock support (3) lock fixed head (5), it is characterized in that the anti-arm-tie (4) that the fixing welding in described lock support (3) outside contacts with the tapered end outer face.

2. a kind of lockset according to claim 1 is prevented drawer structure, it is characterized in that it also is anti-drilling reinforcement steel plate (1) that described anti-pulling-on piece (4) is both.

3. anti-arm-tie according to claim 2 is characterized in that having one to be significantly less than that lock (2) is gone up the tapered end diameter and can to make key insert hole in the tapered end.
