Abstract

The utility model relates to an improved inclined bolt mechanism for door locks, which solves the problem that an inclined bolt of an existing door lock can not be optionally rotate. The utility model is provided with an inclined bolt rod, an inclined bolt, a mounting hole for the inclined bolt, a positioning pin inserted in the inclined bolt, a supporting frame fixed in a lock shell, a soft spring and a handle, wherein, the head part of the inclined bolt rod is provided with an annular groove, and the positioning pin is arranged on one side of the inclined bolt rod and is positioned in the annular groove. The shrinking point of the inclined bolt rod and the handle forms large and small step-shaped cooperation, and the tail end of the inclined bolt rod is provided with a barrier slice; a hard spring is sheathed between the handle and the barrier slice. The utility model can be steered with 180DEG so long as the inclined bolt is pulled out, and after loosened, the inclined bolt can automatically return. The mechanism of the utility model is suitable for both inner opening and outer opening doors.

Description

Door lock can turn to oblique tongue mechanism

The utility model relates to improved door inclined tongue of lock mechanism, particularly a kind of oblique tongue mechanism that turns to.

Tiltedly tongue has another name called and bumps tongue or wind tongue.Present door inclined tongue of lock mechanism as shown in Figure 1, has the oblique tongue rod 1 in lock housing of being contained in 7, oblique tongue 2, oblique tongue installing hole 3, be inserted in the oblique tongue and pass the alignment pin 4 of oblique tongue rod head, be fixed on the support 11 in the lock housing 7, be enclosed within oblique tongue rod 1 middle part and be positioned at the slinky spring 5 in support 11 left sides, be enclosed within oblique tongue rod 1 afterbody and be positioned at the handle 6 on support right side and pass the alignment pin 12 of handle and oblique tongue rod afterbody, by visible this oblique tongue of its structure can not optional turning with in adapting to, the outer door of opening, if will adapt to the change of the direction of opening the door, must take the bonnet of lock and the component of some relative sections apart, handle and to turn to oblique tongue through adjusting.Its process is comparatively complicated.

The purpose of this utility model provides a kind of oblique tongue mechanism that turns to, as long as an oblique tongue is drawn out to outside the inclined tongue hole of lock housing, just can twist 180 °.Decontrol hand, tiltedly tongue is return original position automatically, and it is very easy that oblique tongue is turned to, and the ordinary people is easy to accomplish.Its structure is also very simple.

The utlity model has the oblique tongue rod that is contained in the lock housing, tiltedly tongue, oblique tongue rod installing hole, be inserted in alignment pin in the oblique tongue, be fixed on support in the lock housing, be enclosed within the middle part of oblique tongue rod and be positioned at the slinky spring in support left side and be enclosed within the oblique tongue rod afterbody and be positioned at the handle on support right side, the head of oblique tongue rod has cannelure, alignment pin is located at oblique tongue rod one side and is in the cannelure, thereby oblique tongue rod is linked together and can not separate to deviate from oblique tongue, and tiltedly tongue can freely rotate around oblique tongue rod.The suit place of oblique tongue rod and handle is large and small step-like cooperation, and the tail end of oblique tongue rod is fixed with catch, is with hard spring between handle and the catch.

In the time of will turning to oblique tongue, spur outside the inclined tongue hole that oblique tongue shifts out lock housing, can rotate 180 ° to oblique tongue.Discharge then, by the elastic returning original position of hard spring.Just finished turning to of oblique tongue.

The utility model has the advantages that: one, because the oblique tongue of outward opening door should be towards interior, and the oblique tongue of inward should towards outside, can adjust oblique lingual surface very easily arbitrarily inwardly or outer with this mechanism, be in door that open or external-open all suitable.Two, simple structure.

Fig. 1 is the organigram of oblique tongue of the prior art mechanism;

Fig. 2 is an organigram of the present utility model.

The utility model is described in further detail below in conjunction with example shown in Figure 2:

Fig. 2, tiltedly tongue 2 is connected by the alignment pin 4 that is inserted in the oblique tongue in oblique tongue rod installing hole 3 with oblique tongue rod 1, alignment pin 4 does not intert in oblique tongue rod 1, only be provided in a side of a side of oblique tongue rod 1 and be in the cannelure 8 of this bar, thereby oblique tongue rod is stuck in the installing hole 3, make oblique tongue can not separate to deviate from, but tiltedly tongue 2 can freely rotate around oblique tongue rod 1 with oblique tongue rod.Support 11 is fixed in the lock housing 7 and normally directly utilizes the materials processings of the lock housing 7 at this place itself to form, and slinky spring 5 is enclosed within the middle part of oblique tongue rod 1 and is positioned at the left side of support 11, and handle 6 is enclosed within the afterbody of oblique tongue rod 1 and is positioned at the right side of support 11.The suit place of oblique tongue rod 1 and handle 6 is large and small step-like cooperations, and the tail end of oblique tongue rod 1 is fixed with catch 10, is with hard spring 9 between handle 6 and the catch 10.By slinky spring 5 oblique tongue rod 1 and lock housing 7 are compressed, by hard spring 9 oblique tongue rod 1 and handle 6 are compressed again, be normal operating condition this moment.In the time of will turning to oblique tongue, spur oblique tongue 2 left, to hard spring 9, hard spring is compressed, oblique tongue is shifted out outside the inclined tongue hole of lock housing 7, can rotate 180 ° to oblique tongue by alignment pin 4, oblique tongue rod 1 and catch 10 power transmissions.Discharge then, by the elastic returning original position of hard spring 9.This has just finished turning to of oblique tongue.
