Description

The rolling-gate pick-proof lock

The utility model relates to a kind of rolling gate door lock, especially a kind of rolling-gate pick-proof lock.

At present, during the rolling gate door lock locking used on the market, utilize the cylindrical steel bar in both sides to stretch in wall hole and the leghole,, be easy to prize curved steel bar and open in the rolling-gate inlet chamber as long as insert door end sled upwards with crowbar.Also the someone attempts on housing installing seven font ground hooks and hooks ground hook seat, kicks down client often but the hook seat protrudes ground, if the perforating of hook seat recessed then influence attractive in appearance, and dust, cigarette end etc. easily fill up pit makes hook can not reliably hang tight hook seat.Simultaneously, existing rolling-gate does not have self-locking device, uses inconvenient.

The purpose of this utility model is to provide a kind of and prevents to prize curved steel bar and open the more reliable rolling-gate pick-proof lock of rolling-gate in going into.

The purpose of this utility model is to realize like this, this rolling-gate pick-proof lock is on the basis of original (have on the market and purchase) rolling gate door lock, original driving lever is directly driven the cylindrical steel bar that stretches in the wall hole to be changed into: be connected with pull plate on the driving lever, the front end of pull plate is fixed with axle, activity is with turning sleeve on the axle, the turning sleeve outer wall is provided with helicla flute, the block set that turns to that is installed in the housing is provided with the guide finger that inserts in the helicla flute, the turning sleeve front end connects tapered end by connecting rod (steel bar), the tapered end fore end outer circumference is provided with transverse concave groove, and this groove upwards under the rolling-gate locking state.

As improvement, also be provided with the intermediate hook with tapered end open and close simultaneously on this lock housing body, in ground, be provided with the hook box that matches with intermediate hook, the top board of hook box is parallel to the ground under the effect of spring force.

As further improvement, in pull plate and turn to and be provided with self-locking spring between the block set; Above the rolling-gate leghole, be provided with the pick-proof boss.

Owing to adopt above structure, the utility model rolling-gate pick-proof lock has reliable pick-proof performance, upwards prize as insert the door end with crowbar, then the change of the steel bar at the bottom of the rolling-gate bends towards interior receipts, groove on the tapered end just tightly blocks column and (does not prize and do not block, once the sled card), prevented the phenomenon in prying open rolling-gate goes into effectively.Add that setting up the pick-proof boss above the rolling-gate leghole makes the pick-proof life can be more reliable.Simultaneously, owing to adopt the groove tapered end, use when key operated tapered end turnover leghole convenient freely.Meanwhile, the T shape hook that increases in the middle of the lock (moving simultaneously with tapered end turnover leghole) puts in corner 90 degree behind the ground hook box, and T shape hook hooks the hook seat board, rolling-gate is combined as a whole with ground firmly, and the disconnected T shape hook of non-sled except the robber, otherwise door can't be removed.When rolling-gate was opened, hook box top board is under the effect of spring force, and was concordant with ground, avoids dust, in rubbish such as cigarette end are gone into, both kept attractive in appearance, guaranteed safety (not injuring pin), do not influence the ground hook again and reliably used.Also have, because this rolling-gate pick-proof lock has adopted self-locking spring, the user can then be threaded to locking state with lock when opening rolling-gate, this moment, pushed up to the column sidewall two tapered end ends, only rolling-gate need be pulled down when needing to close and put in place, three volley under the active force of self-locking spring, and the two ends tapered end sticks into leghole, and intermediate hook is blocked the hook seat board; Reverse operating can be opened, and makes the open and close of this rolling-gate pick-proof lock very convenient, laborsaving.And simple in structure, be suitable for promoting.

Below in conjunction with drawings and Examples the utility model is described in further detail.
