Abstract

The utility model relates to a mortice door lock, the latch bolt of which can be reversed, the latch bolt part of the door lock is connected with a latch bolt, a latch bolt limiting spring and a latch bolt carriage by a latch bolt rod, the latch bolt rod is positioned between the latch bolt and the latch bolt carriage and can control the pulling amount of the latch bolt. When the mortice door lock is installed, the reversal action of the latch bolt is finished only by applying an appropriate force to pull the latch bolt by hand to cause the rectilinear face cuboid part of the latch bolt to separate from an inner face plate and rotating the latch bolt at a latch bolt cylinder part by 180 degree and then loosening. The door lock can be installed without opening the lock body or using special tools, the movable parts in the lock body can not get stuck, and the operation is safe and convenient.

Description

A kind of mortise door lock of turning oblique tongue

Technical field

The utility model relates to a kind of oblique tongue overturn structure of mortise door lock lock body.

Background technology

The lock body of blade mortise door lock need be turned oblique tongue when positive and negative door is installed.At present, blade mortise door lock on the market is when turning oblique tongue, all need open lock body or can turn with instrument, complicated operation is loaded down with trivial details, loses time, energy, easily causes damage of product, for the layman, operation is difficulty especially, accidentally will cause the lock body movable part to come off, and need ressemble.

Summary of the invention

In order to solve the problems referred to above of product, the utility model provides a kind of blade mortise door lock of turning oblique tongue, and it need not opened lock housing or use special tool just can easily turn oblique tongue.This mortise door lock is for installation personnel, operate as safe as a house, convenient, fast, do not need any instrument, only with hand applies suitable power and spurs oblique tongue, make oblique tongue face cuboid directly and partly break away from wainscot, tiltedly the tongue cylinder partly rotates 180 ° in wainscot, can finish the action of turning of oblique tongue after unclamping.

The technical scheme that its technical problem that solves the utility model adopts is: the oblique tongue spare to existing mortise door lock lock body has carried out bigger improvement, make oblique tongue with tiltedly become one by relatively-stationary parts between the tongue drawing plate can relative movable parts, thereby make the oblique tongue of upset become simply, make things convenient for, safely, reliably.

Oblique tongue spare of the present utility model is by oblique tongue rod oblique tongue, the oblique spacing spring of tongue to be linked together with oblique tongue drawing plate, becomes a movable part relatively.Tiltedly tongue in wainscot and lock body outward for facing cuboid directly partly, stability is high, with oblique tongue drawing plate cooperation place be cylinder partly, make when overturning oblique tongue, oblique tongue all need not pulled out wainscot, oblique tongue can be overturn, strengthen its reliability.The gap that 0.15mm is arranged between oblique tongue rod and the oblique tongue drawing plate hole, make oblique tongue rod both free to rotate, and don't can produce big reversing and being offset, with the spacing spring string of oblique tongue on oblique tongue rod, place between oblique tongue drawing plate and the oblique tongue rod, and be in initial compressed state, make oblique tongue spare when normal the use, each parts state that keeps relative stability, but and control the pull distance of oblique tongue by the compressible amount of adjusting the spacing spring of oblique tongue.

In the process of the oblique tongue of upset, spur oblique tongue, the drive oblique tongue rod compresses the spacing spring of oblique tongue, and tiltedly tongue drawing plate keeps transfixion, makes oblique tongue face cuboid directly and partly exceeds wainscot 0.5mm, and tiltedly the tongue cylinder partly rotates in wainscot, allows oblique tongue overturn 180 °; Can finish the oblique tonguing of upset; When upset finishes, outer panels covers on the wainscot, because outer panels thickness 1.0mm, greater than pulling out length 0.5mm, so tiltedly tongue cannot be pulled out outer panels, oblique tongue no longer can overturn.

The beneficial effects of the utility model are: when the blade mortise door lock is installed, need not open lock body, do not need any instrument, only with hand applies suitable power and spurs oblique tongue, make oblique tongue face cuboid directly and partly break away from wainscot, partly rotate 180 ° at oblique tongue cylinder, can finish the action of turning of oblique tongue after unclamping.Operation is very simple, convenient, safety, reliable.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Accompanying drawing is blade mortise door lock lock body structure figure;

The A-A sectional drawing is the sectional drawing of oblique tongue spare, and ratio is 2:1.

In the accompanying drawing: 1, oblique tongue spare, 2, wainscot, 3, outer panels, 4, oblique tongue, 5, barrel bolt, 6, the oblique spacing spring of tongue, 7, oblique tongue rod, 8, oblique tongue drawing plate, 9, oblique tongue spring.

The specific embodiment

In figure attached middle school: tiltedly tongue spare (1) is made up of oblique tongue (4), barrel bolt (5), the oblique spacing spring of tongue (6), oblique tongue rod (7), oblique tongue drawing plate (8).Tiltedly tongue (4) is faced cuboid and two parts of cylinder directly, under normal circumstances, cuboid partly in wainscot (2), thereby guarantee its stability; When the oblique tongue of upset (4), with pulling moving oblique tongue (4), compress the spacing spring of oblique tongue (6), the cylinder of oblique tongue (4) is partly entered in the wainscot (2), tiltedly tongue (4) is promptly rotatable.Barrel bolt (5) is riveted oblique tongue (4) mutually with oblique tongue rod (7), and the two is fixing not rotatable.Tiltedly the spacing spring of tongue (6) is gone here and there on oblique tongue rod (7), and is scalable.The oblique tongue rod (7) that is fixed together with oblique tongue (4) links together the spacing spring of oblique tongue (6), oblique tongue drawing plate (8), and becoming one can movable relatively parts.Tiltedly tongue drawing plate (8) works to drive oblique tongue (4) when normal the use; When the oblique tongue of upset (4), oblique tongue spare (1) is played positioning action; When the oblique tongue of pulling (4) upset, it is motionless that tiltedly tongue drawing plate (8) keeps original position; Upset is unclamped hand after finishing, and tiltedly tongue (4) is got back to original position under the effect of the oblique spacing spring of tongue (6).After upset is finished outer panels (3) is covered on the wainscot (2), tiltedly tongue (4) can not overturn again, and tiltedly tongue spare (1) is normal uses.

Claims

1. the mortise door lock of a turning oblique tongue is characterized in that: the oblique tongue spare of lock body by oblique tongue (1), barrel bolt (4), tiltedly tongue drawing plate (5), tiltedly the spacing spring of tongue (6) is fixed together with oblique tongue rod (7), becomes a movable part relatively; Make and need not open lock body when installing or use special tool, can finish the action of turning round of oblique tongue with hand.

2. mortise door lock according to claim 1, it is characterized in that: tiltedly tongue (1) is faced cuboid and two parts of cylinder directly, when the oblique tongue of pulling (1), tiltedly the part of facing directly of tongue (1) exceeds panel (2), and barrel portion rotates 180 ° and finishes upset in panel (2); Oblique tongue rod (7) is fixed on the oblique tongue (1), and tiltedly the spacing spring of tongue (6) string is on oblique tongue rod (7), and tiltedly the spacing spring of tongue (6) plays control oblique tongue (1) pulling amount and reset response; When overturning oblique tongue (1), spur oblique tongue (1) and drive oblique tongue rod (7) the compression spacing spring of oblique tongue (6), upset finishes, and unclamps oblique tongue (4), and under the effect of the oblique spacing spring of tongue (6), tiltedly tongue (1) is got back to normal use location; When normal use, panel (2) is gone up and is covered outer panels (3), spurs oblique tongue (1) at this moment again, because the tiltedly decrement of the spacing spring of tongue (6) restriction, tiltedly tongue (1) is faced directly partly and can not be exceeded outer panels (3), no longer can carry out oblique tongue (1) upset.
