Abstract

A structure modified multi-functional inserting core lock body is provided, which comprises a main panel, a lock shell and a lock interior mechanism. The main panel is provided with three connecting blocks connected with the lock shell; a square tongue connecting block limit hole is of a semicircle and a limit pin matching with the limit hole is riveted on a squire tongue limit plate; a ladder shaft with three different diameters provide sliding platform and guide functions respectively for the square tongue connecting block and the square tongue limit plate; an inclined tongue connecting rod is an integrated ladder shaft, behind which is an inclined tongue reversing device composed of a reversing dial block and a dial block offsetting spring; wherein, the reversing dial block can also position the inclined tongue; an inclined tongue dial wheel supporting post is provided at one side under the inclined tongue dial wheel matching with the inclined tongue connecting rod; two ends of a sliding way riveted on the squire tongue connecting block are bend reversely; wherein, one end bends downward contacts with a lock head jaw and another end contacts with an inclined tongue dial sheet and is also provided with a lock head fixing device. Compared with the existing product, the utility model has the advantages of rational structure and good antitheft performance, and the lock body is free from deformation after adding with pressure, thus making the parts transmit smoothly.

Description

The multi-functional mortise lock body of a kind of architecture advances

Affiliated technical field

The utility model relates to the multi-functional mortise lock body of a kind of architecture advances

Background technology

Present existing mortise lock body is made of main panel, lock body shell, lock body internal mechanism.But lock body structure is unreasonable, main panel middle part and lock body shell have the slit, on side's tongue limiting plate two pilot holes are arranged, side's tongue limiting plate one projection of bending cooperates the other side's tonguing row spacing with the square breach that square tongue connects piece, limiting plate bend card when being raised with not the side's of advancing tongue connect the breach of piece, riveted square tongue connect on the piece with the tapered end pusher dog and tiltedly the tongue plectrum cooperates that the slide plate of opening oblique tongue is easy to intersect dislocation with tapered end pusher dog or oblique tongue plectrum, can not open oblique tongue with key, be used for oblique tongue spacer that oblique tongue turns over tongue and location and be located at oblique tongue small end and the oblique parallel position of tongue connecting rod, when opening oblique tongue, tiltedly the tongue spacer only touches mutually with the top of oblique tongue pull bar, belong to eccentric location, under the pressure of opening, tiltedly tongue is with tiltedly the generation of tongue pull bar is loosening, the transmission of lock body side pressurization rear locking shell distortion inner body is malfunctioning, and lock body inside does not have the tapered end fastening devices, is necessary to provide a kind of multi-functional mortise door lock lock body rational in infrastructure.

Summary of the invention

In order to overcome the various problems that existing mortise lock body unreasonable structure causes, the purpose of this utility model provides a kind of multi-functional mortise lock body rational in infrastructure, and this novel mortise lock body is on the basis of traditional mortise lock body, improves.Part ensuring smooth transmission in this lock body structure novelty, the lock body.

For achieving the above object, the utility model is taked following design scheme: three contiguous blocks are set on the lock body main panel are connected with lock body shell, side's tongue connects the piece spacing hole for semicircle, the position-limitting pin riveted that is mated is on square tongue limiting plate, the pilot hole of side's tongue limiting plate, position-limitting pin, limiting plate return spring supporting lug is axis and arranges, multidiameter that three kinds of different-diameters are arranged connects the effect that piece and square tongue limiting plate provide sliding platform and guiding respectively for square tongue, tiltedly the tongue connecting rod is a whole multidiameter, in its back is the Inclined bolt direction changing device, by turning over the tongue shifting block and the shifting block return spring is formed, turning over the tongue shifting block also can play the role of positioning to oblique tongue, there is a thumb wheel support column side of the oblique tongue thumb wheel below that cooperates with oblique tongue connecting rod, riveted oppositely bends at the slide plate two ends that square tongue connects piece, an end that bends downwards touches mutually with the tapered end pusher dog, and the other end touches mutually with oblique tongue plectrum.Also be provided with the tapered end fastening devices.
