Description

Security door is locked up and down inserts slack adjuster

Technical field

The utility model relates to security door technical fields, lock up and down more particularly, to a kind of security door and insert gap adjustment dress It sets.

Background technique

Currently, the security door of security door producer production, the either structures such as simple gate or clamshell doors, big and small door, upper underthrust Lower gear uses substantially on the corresponding doorframe of pin rushes single kidney slot mode, and the stainless of a drawing and forming is then buckled into hole Steel dust cover or plastic jacket.

This structure exists as following drawbacks: first is that the kidney slot that lower gear rushes on doorframe is greatly by about one time than upper and lower lock plug, leading Cause is shut behind the door, and door-plate upper and lower ends can shake under external force；Second is that being deposited in doorframe and door-plate process in production In dimensional discrepancy, easy deviation cannot lock, and assemble the lockhole that will polish at this time；Third is that being used after user installation Middle door-plate abnormal condition lower switch is not capable of resetting since accidental impact causes to lock to insert to deform, and user cannot oneself adjustment.

For this purpose, many manufacturers and knowledgeable people develop and manufacture experimently regarding to the issue above, but there has been no more so far It emerges for reasonable product.

Summary of the invention

In view of the deficiencies of the prior art, the utility model provide it is a kind of it is easy for operation, simple and reasonable, be easy plus Work, not only beautiful but also dust-proof, safe and practical security door, which had had to lock up and down, inserts gap adjustable device.

The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of security door is locked up and down inserts gap adjustment Device inserts lash adjusting device, door-plate, the tapered end sheath being mounted in door-plate, lock including doorframe, the lock being fixed on doorframe Head；It includes gap trimmer, dust cover, fastening screw that the lock, which inserts lash adjusting device,；Gap trimmer and dust cover are folded Be fixed on doorframe, gap trimmer be equipped with sliding slot and flange, the movement of sliding slot tightened relative screw be conveniently adjusted flange with The gap of tapered end, to reach the adjustment slotting gap of lock up and down.The tapered end can be arranged up or down by tapered end sheath It locks in door-plate and with adjustment film perforation in the trimmer of gap or separates cooperation, the transmission mechanism of tapered end is mounted in door-plate, lock Item is connected between tapered end and transmission mechanism, and transmission mechanism and bolt drive tapered end to move up and down in adjustment film perforation.

The further scheme of the utility model, the gap trimmer that gap adjusting structure is inserted in described locking up and down are equipped with flange It is matched with the dust-proof cage apertures being equipped in dust cover, sliding slot is parallel with hole flanging threaded hole to be superimposed upon on doorframe.

The further scheme of the utility model, the dust cover that gap adjusting structure is inserted in described locking up and down are equipped with hole flanging spiral shell Pit is adjusted dust cover and gap with fastening screw behind the gap for adjusting flange and tapered end that gap trimmer is equipped with Piece is fixed on doorframe.

The further scheme of the utility model, the door-plate, which is equipped with, inserts the pick-proof that adjustment structure matches with upper and lower lock Side.

The beneficial effects of the utility model are: lash adjusting device is inserted first is that being equipped on doorframe and locking up and down, when door-plate closes When closing lock, tapered end insertion under bolt drive, which is locked, is inserted in lash adjusting device, is adjusted tapered end at this time and is locked and inserts gap adjustment Gap between device, the shaking generated when it is possible to prevente effectively from door-plate upper and lower ends are by external force.Second is that the ruler in production and processing Very little deviation cannot lock, and can be locked in assembly by locking the adjustment of slotting lash adjusting device up and down, be unlikely to doorframe of polishing Lockhole.Third is that user cannot lock after leading to tapered end collision deformation in improper switch gate, user oneself can use screwdriver pine It opens to lock up and down and inserts the position that the fastening screw on lash adjusting device carries out front and back adjustment gap trimmer, guarantee the normal work of tapered end Make, is easy to use.Fourth is that inserting lash adjusting device even if cancelling and installing lower lock, security door still be can be used normally at this time, no It is affected.
