Abstract

A self-locking type roller-blind door lock is capable of locking the door or unlocking within doors without a key and adjusting the position of the lock after the roller-blind door is assembled. Adjustable lock clips are respectively arranged on both sides of a guide slot; for adjusting, the lock clips can move up and down through easing screws on the lock clips and be fixed at a proper position through tightening up the screws again. A telescopic lock head is respectively arranged on the front end of a lock rod, and a return spring arranged inside a lock body is capable of making the lock rod and the telescopic lock head keep extended. A manual handle arranged on one side of the lock body facing inwardly can drive the lock rod to telescope; when the door is needed locking, the door is pulled down, the telescopic lock head can retract once touching the lock clips and can automatically spring up when the lock head is below the lock clips, and the door can be automatically locked. When the door is needed unlocking within doors, a manual switch is turned to make the lock rod drive the telescopic lock head to retract and break away from the lock clips, and the door is unlocked without a key within doors.

Description

The self-locking rolling gate door lock

Affiliated technical field

The utility model relates to lock a door a kind of lockset of locking a door automatically of mode of rolling-gate, and this novel lock does not need to use key when locking a door or open the door in doors, just can lock a door or open the door in doors; And use novel lockset after rolling-gate installs, can be according to the height of the height easy adjustment lock-bit on ground.

Background technology

The structure of the rolling gate door lock that is using at present, by: lock body, locking bar and one fixedly screens form; When opening the door or lock a door, need twist locking bar with key and just can open or lock a door, can be cumbersome when particularly will hold or lock several fans door simultaneously, take looking for for a moment that bunch of keys try, could allow key check the number to open or lock a door; The lockset that uses is after rolling-gate installs at present, lock-bit is fixing dead, general new house ground just real worker after rolling-gate installs, cause the too high and lock in ground not to the doorstep or can dodge very big slit after low excessively the locking a door easily, advance the thing of reptile or mouse and so on easily, need lock-bit secondary construction meeting is cumbersome; Also having when shop front room and fit up again, constructs again and also can have the problems referred to above in ground; Old man and children use present lockset to open or lock a door also certain difficulty.

Summary of the invention

Become easier in order to get out of the way or to lock rolling-gate, can regulate the height of lock-bit after allowing rolling-gate install, the utility model provides a kind of self-locking rolling gate door lock, and this lockset does not need key when locking a door or open the door in doors, only needs to move door to the end when locking a door and just can automatically lock; Only need when opening the door in doors hand switch can be opened the door once twisting; The rolling-gate that uses this novel lockset can be regulated the height of lock-bit after installing, the too high lock that can avoid ground to do to the doorstep can the very big slit of sudden strain of a muscle or too low.

The technical scheme that its technical problem that solves the utility model adopts is: return spring is installed in lock body, make locking bar remain extended configuration, load onto flexible tapered end respectively at the locking bar two ends again, the both sides guide groove is loaded onto adjustable pintle hook lock respectively, when locking a door, only needs door toward pulling down to the end, meeting pinch in when flexible tapered end touches pintle hook lock, again down the time, flexible tapered end has arrived and can eject automatically below the pintle hook lock, thereby realizes locking a door without key; Lock body is installed hand switch to one side within doors, and hand switch links to each other with internal gear, when the twisting hand switch, can allow locking bar drive flexible tapered end and shrink, and opens the door within doors without key thereby be implemented in; Adjustable pintle hook lock is made up of ten centimeters long bases and a pintle hook lock moving up and down, base is fixed in two side guidances, when needs are adjusted lock-bit, only needs the Luo silk on the pintle hook lock is unclamped, can move up and down, again the Luo silk be tightened fixedly pintle hook lock to the position that is fit to.

The beneficial effects of the utility model are: allow the rolling-gate Shi Buxu key of locking a door or open the door in doors, use and easy for installation, but the height of easy adjustment lock-bit after the installation, the inconvenience of avoiding secondary to construct makes old man and children easy to use.

The specific embodiment

In Fig. 1, base (1) is separately fixed in the both sides of rolling-gate guide groove, pintle hook lock (2) is installed in base (1) inside, and in the end insertion displacement groove (3), Luo silk (10) is arranged on the pintle hook lock (2), when unscrewing Luo silk (10), pintle hook lock (2) can move up and down 10 centimeters in base (1) and displacement groove (3), behind the position that is fit to, fixedly during pintle hook lock (2), Luo silk (10) tightened get final product, so just can after installation, can regulate the height of lock-bit; Fixed bin (4) is installed in the two ends of rolling-gate door sheet respectively, and allow flexible tapered end (9) and guide groove inside keep 0.5 centimeter distance, usually the distance of door sheet and guide groove is the 2.5-3 centimetre, pintle hook lock (2) is installed a distance of sheet 0.5-1 centimetre of should keeping at a distance, lockset just can not produce the scratching phenomenon when using rolling-gate like this, after installing, when with door down during the zip door, when flexible tapered end (9) touches pintle hook lock (2), the meeting pinch in, arrived below the pintle hook lock (2) when following time again, can allow tapered end eject, so just locked a door automatically without key because flexible tapered end (9) back is equipped with spring (8); Install hand switch (5) at lock body (6) towards one side within doors, hand switch (5) links to each other with driving cog (12) with gear (13) with handle driver blade (15); When indoor opening the door, turn hand switch (5), make locking bar (7) drive flexible tapered end (9) and shrink the restriction that breaks away from pintle hook lock (2), just can open the door in doors without key.

In Fig. 2, gear (13) and lock core (14) and lock core driver blade (16) and handle driver blade (15) are on same concentric shafts; Lock core (14) links to each other with lock core driver blade (16); Handle driver blade (15) links to each other with hand switch (5); Be to contact and transmission between handle driver blade (15) and lock core driver blade (16) and the gear (13) by protruding post (17); When one of them rotates separately when lock core (14) and hand switch (5), can not drive the other side rotates, gear (13) can only be rotated half-turn towards the direction of unblanking, return under the effect of spring (11) then, and make driving cog (12) drive locking bar (7) and flexible tapered end (9) remains extended configuration.
