Abstract

The utility model relates to a contact-closing type four-point three-direction insertion-bolt door lock, which is composed of a shell body (1), a rotary member (22), an upper and a lower transverse lock bolts (5) and (17), an upper and a lower lock bolts (2) and (18), and a locking head (19). The utility model is characterized in that a connecting plate (7) is arranged between the upper and the lower transverse lock bolts and is provided with a hook rod hole (10) and is fixedly provided with a contact-closing pin (12), one end of a contact-closing rod extends out of the shell body (1) when the transverse lock bolt retracts, a hook piece (8) is provided with a hook rod (9) and a push rod (11), and a spring (21) and a block (26) force the hook rod to be in the position of the hook rod hole; the locking head (19) causes a locking piece (28) to move upward or downward, and a locking piece (30) is provided with an inner side (25), so the transverse lock bolts can not retract; when the contact-closing rod (13) is touched, the hook rod releases the connecting plate and the lock bolts extend out, and then the door can be locked if the locking head is rotated. Therefore, the door can be locked and unlocked very conveniently.

Description

Touch 4 Three-bearing mortise door locks of enclosed

The utility model relates to lock, particularly uses the lock of key.

The lock that is used for security door or warehouse door now, how to have the wind tongue separately, also need turning handle or key that locking bolt is stretched out when locking a door, changeing key again could lock, therefore more bothersome, the then i.e. locking after on the door knob that has if the careless wind such as (as tip rubbish) of temporarily going out is shut door then locked, as is not with key will bring many inconvenience.

It is extended door to be barred up that the purpose of this utility model provides a kind of touching back locking bolt, and key can be with door locked, the backward rotation key can be unblanked 4 Three-bearing mortise door locks of enclosed that touch easy to use.

The purpose of this utility model realizes by following technical scheme, originally touch 4 Three-bearing mortise door locks of enclosed and have housing, rotating part, be loaded on the handle in the rotating part, last cross locking bolt, following cross locking bolt, last locking bolt, following locking bolt, tapered end, make, following cross locking bolt ejects the spring of housing, it is characterized in that said going up between cross locking bolt and following cross locking bolt has junction plate, the shank hole is arranged on the junction plate, also be fixed with on the junction plate to touch and close pin, touch and close pin and have the touching of spring action that have that its end still stretches out in outside the housing when cross locking bolt retraction housing to close bar, touching the other end that closes bar stretches out on junction plate, rotating hook spare has shank and the push rod that has gib head, the position that spring and block limit hook spare makes shank perpendicular to junction plate, the said other end that stretches out on junction plate that closes bar that touches is abutted against mutually with push rod, opposite side at the cross locking bolt of housing has locking piece moving up and down, its width should equal the inner limit of cross locking bolt when the cross locking bolt stretches out and can be abutted against mutually with the inner side edge of locking piece, the following dialing part that is connected in tapered end acts on mutually with locking piece, said go up have on locking bolt and the following locking bolt with the cross locking bolt on sideslip follow closely the push/pull slot that acts on mutually and make itself and cross locking bolt stretch out simultaneously or withdraw, on the lateral pin bolt bearing pin is arranged, the long driving lever that acts on mutually with bearing pin is arranged on the rotating part.

Originally touch 4 Three-bearings of enclosed and insert the ostium lock, when locking bolt indentation housing, penetrate the shank hole of junction plate and hook junction plate and locking bolt can not be ejected,, touch and close the bar withdrawal and promote push rod, shank is rotated and decontrol junction plate when touching when closing bar by shank; Therefore locking bolt ejects, turning handle was also stirred by long driving lever and can be made the locking bolt withdrawal also can be hooked by shank again and no longer eject this moment, when locking bolt stretches out, key is rotated tapered end and that locking piece is moved to is upper, the inner side edge of locking piece is abutted against mutually with the inner limit of cross locking bolt and can not withdraws, and locks locked, make key go back to original position, can extract key, when desiring to unblank, only need the backwards rotation key, locking piece is back to the next, then locking bolt can be withdrawn and turning handle can open the door, and therefore only need close the door, and locking bolt is stretched out, key is changeed a low-angle (as 45 °) can lock a door, backwards rotation key one low-angle can be unblanked, and is very convenient.
