Abstract

The invention relates to a frictionless automatic touch bolt ejecting mechanism, which comprises a lock box assembly and a touch bolt clutch assembly, wherein the lock box assembly comprises a lock box and a guide plate, is arranged in the lock box and comprises a touch bolt, a connecting rod, a touch bolt spring, a touch bolt baffle sheet, a touch bolt support frame, a touch bolt pulling sheet, a gravity clutch hook, a reset torque spring, a connecting sheet, weight balancing iron, a clutch positioning shaft and a connecting sheet rivet, the touch bolt is arranged on the connecting rod and can extend out of the guide plate, the outer end surface of the touch bolt is in a straight surface structure parallel to the guide plate, the middle section of the connecting rod is sheathed with the touch bolt support frame in a hollow way, the touch bolt spring is sheathed on the connecting rod, one end of the touch bolt spring is connected with the touch bolt, and the other end of the touch bolt spring is connected with the touch bolt support frame. The touch bolt of the frictionless automatic touch bolt ejecting mechanism does not have the friction with a door frame, a lock tool and a door can not be easily damaged, the service life is long, a lock bolt is hidden in the lock box in the normal state and can not be hooked or hung with people or objects, in addition, the integral appearance is good, the change on the existing lock box is small, the structure is simple and stable, and the existing inclined touch bolt can be generally replaced.

Description

Do not have friction and bump the tongue ejecting mechanism automatically

(1) technical field

The present invention relates to the mechanical lock technical field, the tongue ejecting mechanism is bumped in particularly a kind of nothing friction automatically.

(2) background technology

At present, in lock technology field, tiltedly tongue exists simultaneously because practical and convenience is widely used, and 1, tiltedly tongue for a long time and the doorframe friction can cause the mutual damage of oblique tongue, door and lock box; 2, tiltedly the tongue normality for stretching out the lock box state, easy and people or thing generation hook, and influence attractive in appearance; 3, the oblique tongue with inclined-plane is easily by slice substance with collude the shape thing and open, deficiencies such as poor safety performance, for overcoming the above problems, people have proposed the various nothings automatic latch that rubs, but the automatic latch of existing nothing friction has the following disadvantages: 1, this lock box is brand-new design basically, can not unconditionally exchange with existing lock box; 2, the contact is arranged, the door gap requires high, can only reduce friction; 3, do not have the friction magnetic latch and can not be widely used in the metal iron door, and the lock box material there is specific (special) requirements, the cost of manufacture height.

(3) summary of the invention

In order to solve above deficiency, the invention provides the friction of a kind of nothing and bump the tongue ejecting mechanism automatically, use the tongue that bumps of this mechanism not need the inclined-plane, normality is hidden in the lock box and does not expose, and is easy to use, the life-span is long, and security performance is good.

For this reason, the present invention takes following technical scheme:

The tongue ejecting mechanism is bumped in a kind of nothing friction automatically, comprise the lock box assembly and bump the tongue clutch component, described lock box assembly includes lock box and guide strip, the described tongue clutch component that bumps is installed in the described lock box, the described tongue clutch component that bumps includes and bumps tongue, connecting rod, bump the tongue spring, bump the tongue catch and bump the tongue support, bump the tongue plectrum, gravity clutch hook, reduction torsion spring, brace, balance weight iron, clutch locating shaft and brace rivet, the described tongue that bumps is installed on the connecting rod, bump tongue and can be extended out guide strip, the described outer face of bumping tongue is the structure of facing directly of parallel guide strip, described connecting rod stage casing is set with bumps the tongue support, the described tongue spring housing that bumps is contained on the described connecting rod, one end with bump tongue and be connected, the other end with bump the tongue support and be connected, described connecting rod afterbody is set with the described tongue catch that bumps, and locatees by limited block; The described tongue plectrum that bumps is installed on the shifting block axle, and the shifting block axle is connected with lock box; Described gravity clutch hook is installed in the described lock box by the clutch locating shaft, is provided with reduction torsion spring between described gravity clutch hook and the lock box; The adjacent gravity clutch of described brace hook is arranged, the top of described gravity clutch hook is provided with and bumps the crotch that the tongue catch cooperates, the afterbody of described gravity clutch hook is provided with the catch that offsets and locate with described brace, described brace is connected with lock box by described brace rivet, and described brace is provided with balance weight iron away from the other end of gravity clutch hook.

The described tongue catch that bumps is provided with projection, and described lock box is provided with for bumping the through hole that tongue catch projection is passed through.

Operating principle of the present invention is: bump the tongue afterbody and be provided with the gravity clutch component, after bumping the tongue assembly and being bumped the tongue plectrum and be pressed into lock box, the effect that the gravity clutch is hooked in reduction torsion spring down with bump the tongue catch and form hook-shaped the connection, finish locking, when door contacts with doorframe since seismic element iron continue to a direction motion, the rotation of brace pulling gravity clutch hook has been removed gravity clutch hook and has been bumped the hook-shaped of tongue catch and be connected, and bumps the tongue assembly and finishes and automatically lock bumping under the effect of tongue spring force the ejection lock box.

Employing the present invention have the following advantages: 1, bump the not friction of tongue and doorframe, it is long that lockset and door are not easy to damage the life-span; 2, the dead bolt normality be hidden in the lock box not can with people or thing generation hook, and overall appearance is good; 3, the outer face of bumping tongue is the structure of facing directly of parallel guide strip, that is, the head that bumps tongue is a squared design, has effectively avoided slice substance and has colluded the danger that the shape thing is opened, safe overall coefficient height; 4, existing lock box is changed little, simple and stable structure, can generally substitute existing inclined-plane and bump tongue.
