Abstract

The present invention provides a door lock handle which comprises a main body, an operating shaft, a handle, a small gear, a pair of toothed racks, rods and a clamping ball, wherein the main body is provided with a groove-shaped concave part which protrudes to the back surface of a door; the operating shaft can rotate and can not axially slide, and is installed on the main body; the handle is rotatablely supported on the base end part of the operating shaft, and is contained in the groove-shaped concave part when the door is locked; the small gear is fixed on the front end of the operating shaft; the toothed racks are provided with toothed parts which are meshed with the small gear and are guided by a cover which is fixed on the main body, and the toothed racks only can slide up and down; the rods are fixed on the front ends of the toothed racks, and the front end of each rod can be clamped with and separated from a lock pin seat beside a fixed frame body; the clamping ball is arranged on the front end of the handle and can be elastically pressed to extend by a spring, and the clamping ball can be clamped with and separated from a notch of the operating shaft.

Description

Door locking handle assembly

The present invention relates to a kind of door that is used to lock distribution board storage case etc., take in the door locking handle assembly that can be rotated to support on the handle on the control shaft that is fixed with pinion in the slotted recess that is arranged on the main body.

The door locking handle assembly of distribution board storage case had proposed the scheme of various structures.But, determine that the amount that protrudes in a surface that can lock is big, on the contrary, what overhang was little can not lock again fully, and the door locking handle assembly that satisfies two kinds of requirements does not also develop now.

Therefore, purpose of the present invention just provides the door locking handle assembly that a kind of amount that protrudes in a surface is minimum and can lock really.

If adopt the reference number in the accompanying drawing to describe, a kind of door locking handle assembly then of the present invention comprises: be fixed on the main body (2) on the door (1); Turn and can not be installed in axially slidably the control shaft (5) on the main body (2); Can be rotated to support on the handle (4) of the base end part of control shaft (5); Be fixed on the pinion (6) of the front end of control shaft (5); Be provided with a pair of tooth bar (7) that only can slide up and down with the tooth portion (8) of pinion (6) engagement, by cover (17) guiding that is fixed on the main body (2); Be fixed on the front end of tooth bar (7), front end can engage with the locking pin seat on fixed frame side, the bar (9) that separates, it is characterized in that: described main body (2) has to the outstanding slotted recess (3) of the rear side of door (1), described handle (4) is accommodated in when locking in this slotted recess (3), take in by spring (11) at the front end of handle (4) and to make it suppress the engaging ball (10) that stretches out, be arranged on the pit (12) that engages ball (10) engaging when pulling out handle (4) with this, the pars intermedia that locking bar (13) can this handle (4) is slided, at this locking bar (13) hook portion (14) that engages with hook (16) in this slotted recess (3) go up to be set, and be arranged on the spring (15) that suppresses this locking bar (13) on this hook portion (14) and the direction that engages of hook (16), when locking, the position in the slotted recess (3) that handle (4) is remained on be accommodated in main body (2).

When unblanking, finger is put in the gap of the lower end of handle 4 and slotted recess 3, pull out handle 4.When handle 4 is rotated for middle mind-set prescribed direction with control shaft 5, be fixed on pinion 6 rotations on the control shaft 5, a pair of tooth bar 7 above-below directions that are provided with the tooth portion 8 of meshing with this pinion 6 slide.Be fixed on the locking pin seat that the front end of bar 9 of the front end of tooth bar 7 breaks away from the fixed frame side, thereby lock is opened.

Fig. 1 is the right view of the door locking handle assembly of one embodiment of the invention.

Fig. 2 is the front view of this lock handle assembly.

Fig. 3 is the rear elevation of this lock handle assembly.

Fig. 4 is the sectional view along the A-A line of Fig. 2.

Embodiment shown in the figure, the front end of handle 4 be with crossing the base end part that pivot pin 18 is bearing in control shaft 5, and the front end of this handle 4 keeps in blind hole 20 radially and suppresses spring 11 and engaging ball (Network リ Network ボ one Le) 10.This engaging ball 10 is stuck in the recessed of control shaft 5 and resists in 12 when handle 4 is pulled out from slotted recess 3.The centre of handle 4 be equipped with cross its slips of pin 21 guiding, be provided with slotted recess 3 in hook 16 engagings, the locking bar 13 of the hook portion 14 of separating, this locking bar 13 makes it have the trend that moves to the direction that engages by spring 15.

Control shaft 5 is decomposed into the first half 5a of handle 4 connections and latter half of 5b, first half 5a and the latter half of 5b of internal pinionmw 6 formations is connected, and makes its one rotation, and clamps connection with Screw 19.

As mentioned above, door locking handle assembly of the present invention owing to be provided with the slotted recess 3 of stretching to door 1 the back side on main body 2, is accommodated in handle 4 in this slotted recess 3 when locking, so that handle protrudes in the amount on a surface is minimum.Owing in the front end of handle 4, keep spring 11 and engaging ball 10, so, this engaging ball 10 with handle 4 when slotted recess is pulled out, be stuck in the pit 12 of control shaft 5, support handle 4 really owing to suppressing of spring 11.Owing to the hook 16 that is installed with slidably in the centre of handle 4, is provided with in the slotted recess 3 engages, the locking bar 13 of the hook portion 14 of separating, make this locking bar 13 have the trend that moves to the engaging direction by spring 15, therefore, when locking, handle 4 can be accommodated in the slotted recess 3 really, needn't worry to stretch because of carelessness and hinder current etc.
