Description
Technical field
The utility model relates to a kind of security door snap close, particularly a kind of adjustable locker.
Background technology
In order to prevent to trespass, guarantee unit and family's property and personal safety, every household has all been installed the good security door of theftproof performance.But in use there is following problem in present security door: the snap close mode of security door mostly is the lockset dead bolt greatly and stretches in the lockhole that is installed in the latch plate on the security door doorframe, because the sum of errors panel beating error accumulation of spare and accessory parts itself together, make fitting allowance big, cause the influence of security door snap close tension to be opened, or locking is crossed loose door leaf and is rocked and be easy to generate noise, thereby reduce theftproof, sealing and the heat-insulating property of security door, and shortened the life cycle of security door greatly.Improve the increase manufacturing cost that the accuracy of manufacture then can be at double simply, and reduced production efficiency.For this reason, many manufacturers and knowledgeable people research and develop at the problems referred to above, but do not have desirable product to emerge on market so far as yet.Therefore, developing a kind of adjustable locker is urgent problem.
Summary of the invention
In order to overcome the above-mentioned shortcoming that existing security door snap close exists, the purpose of this utility model provide a kind of simple and reasonable, the snap close degree of tightness is easy to adjust, the service-strong security door can be regulated locker.
The technical scheme that its technical problem that solves the utility model adopts, it comprises latch plate, the snap close support, the snap close support is fixedlyed connected with latch plate by two arms, two arms of described snap close support are provided with positioning step, the bottom of snap close support is provided with at least two vertical equally distributed salient points, on the positioning step of snap close support, be provided with movably keeper, the bottom of keeper is provided with preformed hole, between keeper and snap close support, be provided with rotating spiral regulating part, the bottom of spiral regulating part is provided with spiral and regulates guide rail, spiral is regulated guide rail and is stuck in the groove that forms between the adjacent salient point, the top of spiral regulating part is provided with regulates the cap head, and this adjusting cap head passes the preformed hole of keeper from the bottom of keeper.
Be fixed on the doorframe for the ease of latch plate, described latch plate is provided with the fixing hole that is connected with doorframe.
After adopting said structure, the utility model has following advantage and effect: the one, adjust the position of keeper in the snap close support by regulating the spiral regulating part, and remedied fitting allowance, pine or tension phenomenon appearred after thoroughly having solved the security door locking; The 2nd, adjust when being convenient to assemble, improved production efficiency, help field erected adjusting of security door and maintenance simultaneously, guaranteed theftproof, sealing and the heat-insulating property of security door.
