Description

Rotary bolt and lock for double swing door

The utility model belongs to the lock class, but is to be used for rotary door bolt lock door on the double swing door and equal device of opening/closing door door bolt inside and outside door.

Often adopt double swing door on conference room, office building, restaurant and other places, the common mode of locking a door is double swing door to be closed close fixing with dead bolt, because dead bolt is shorter, the stranger can hit dead bolt to take off or damage and open the door with the bump method, and seeming, it is not too firm to lock a door.Country residents particularly, traditional double swing door are to bolt the door with a bolt mortise lock or a door thick stick in door, and it is more firm to lock a door, but uses inconvenience, especially when the people goes out, can only add lockset in addition and lock a door.

Therefore, but designing a kind of simple and practical, user all opening/closing door bolt lock door and device of opening the door inside and outside door, is technical assignment of the present utility model.

Major technique structure of the present utility model is made up of pin tumbler lock and bolt etc., characteristics are that the knob axle of inserting connection with door lock core is arranged, be fixed with gear on the knob axle and be set with return spring, the sector gear that matches with this gear is sleeved on the axle of fixing with door-plate, be associated with notched bolt on the sector gear, this breach can be chimeric at the fixed axis that bolt rotates on back and another door-plate.

Its technical pattern also comprises:

Door lock core is packed on the outer handle of Yishanmen, on the handle, on the Yishanmen inside and outside handle is housed also in addition in push button shaft is slidingly mounted on, all inside and outside handle is connected firmly on door-plate by bolt, bolt rotates the breach of back on it, can be chimeric with another the set bolt axle of interior handle.Also but multi pack has sector gear anti-rotation locking mechanism.

After implementing said structure, the user goes out at closing time, uses the key rotational lock core, drive the widely different together commentaries on classics of gear on the knob axle, the sector gear that is meshed simultaneously drives bolt and rotates, and makes it on breach and another fixed axis of fanning on the door-plate chimeric, and double swing door is just locked securely by bolt; When outward opening door, the backward rotation lock core makes the oppositely widely different position that goes back to of bolt at last.When closing the door or opening the door, need only press the knob axle indoor, it be cogged move axially thereupon, cause with sector gear and disengage, the bolt that links with sector gear is free rotary state, makes that breach and other Yishanmen are pulled on it fixed axis is chimeric promptly locks a door, and separates and promptly opens the door.Safer insurance when guaranteeing that double swing door is locked a door can use latch in addition at Men Nei, inject simultaneously that sector gear is pulled and the hole of door-plate in, make sector gear locking anti-rotation, even can not make the sector gear rotation with key outdoors.If the said structure multi pack on the inside and outside handle of double swing door, not only can be kept aforementioned repertoire, also make device more become both artistic and practical, satisfy the different levels consumer need.

Fig. 3 is that the utility model is packed in the signal of front view outdoors when going up of double swing door handle;

Fig. 4 is that the B-B sectional view of Fig. 3 amplifies signal;

Fig. 5 is a kind of gear (5) anti-rotation locking mechanism;

Fig. 6 is another kind of gear (a 5) anti-rotation locking mechanism;

Fig. 7 is inside and outside handle installs usefulness on door an another kind of stud.

From Fig. 1, Fig. 2 as seen, primary structure of the present utility model is by the outer lock cylinder (1) of door-plate I, insert the push button shaft (2) that joins with the lock core tail end, be fixed with gear (3) on the push button shaft and be set with return spring (4), on the fixed axis (6) of sector gear (5) suit of gear (3) engagement and door-plate I, and sector gear (5) is associated with the bolt (7) of band breach (19), and bolt rotates back breach (19) can be chimeric with the fixed axis (8) of door-plate II.

Said structure is to rotate some weeks (one week or two weeks of example) with key closing the door outdoors, gear (3) is stirred sector gear (5), bolt (7) is set level and breach (19) imbeds the door-plate II fixed axis (8) is carried out locks a door, after transfering to key, by the chimeric location of lock cylinder, bolt (7) can not arbitrarily rotate.Opening the door outdoors is with key some weeks of backward rotation, make bolt (7) be inverted to vertical direction, breach and axle (8) and break away from, and chimeric because of lock cylinder, bolt is relative positioning also.If in the door inward or close the door, only need by pressing push button shaft (2), make gear (3), break away from engagement with sector gear (5), bolt (7) can freely be stirred and open the door or close the door, and bolt (7) is decided in push button shaft return backgear (3), (5) engaging pin again.

For making the utility model good looking appearance, more becoming practical, can door lock core (1) directly be packed in door pull on the outer handle (9) of I as shown in Figure 3, Figure 4, push button shaft (2) is slidingly installed within it on the handle (10).Door is pulled inside and outside handle (10) on the I, (9) and door and is pulled inside and outside drawing on the II, all connect firmly turncap (12) on bolt (11) (example likeness in form hexagonal (hexagon)nut or gib head garden nut), with bolt 11 inside and outside handle is clamped and is packed in and pull by rotation.Wherein sector commentaries on classics (5) is sleeved on the axle sleeve (13) of pulling the following square bolt (11) of handle (10) in the I.With bolt (7) breach (19) fixed axis (8) of the door-plate II of embedding mutually, in pulling with this door handle down the axle sleeve (13) on the square bolt (11) replace (square bolt (11) structure is similar down to pull in the I handle with door, does not have figure).

Carry out the pass behind the door at bolt (7), personnel prevent to have outdoors the human key to open the door and swarm into because of needs in the room, and sector gear (5) anti-rotation locking mechanism can be set.Its form can be as shown in Figure 5, pull the corresponding position and respectively establish hole (14), (15) at gear (5) (or on bolt) and door, when bolt (7) closes behind the door, hole (14) and (15) are just in time aimed at, and the people need only inject latch (16) and lock anti-rotation in the room; Also can be as shown in Figure 6, after bolt (7) imbeds fixed axis (8) (or axle sleeve (13) of bolt (11)), pull strong magnets (18) on (17) with the rotation that is contained in bolt (7) end, the adhesive bolt seals breach on it (19), bolt is locked relatively, rotation can be pulled (17) at ordinary times and roll up, be attached to the bolt side by direct suction of magnet (18); Also can adopt the rotor plate lid that is contained on the interior handle (10), cover push button shaft (2) end of pressing state after the rotation, make gear (3) keep disengaged position, key no longer can drive sector gear (5) rotation thereby make outdoors.

In order to make inside and outside handgrip easy for installation on door is pulled, can use the bolt (11) among stud (11 ') the replacement Fig. 4 that is with turncap (12) as shown in Figure 7, and stud two ends respectively are positive left-hand thread.
