Abstract

The utility model relates to a latch operating structure for a door lock, wherein, a rotary shaft (3) is sheathed with a brake piece (4), one side of the brake piece is respectively provided with a latch stop piece (5) and a latch relieve piece (6) which are arranged from top to bottom, and a linking piece (7) is arranged between the latch stop piece and the latch relieve piece to connect the two pieces; an arresting stop rod (8) is arranged above the latch stop piece, and the upper part of the arresting stop rod (8) is arranged in a push post of a lock tongue. In a normal state, the bottom end of the door lock pushes and supports the brake piece to drive a latch to be in the opening state; when the latch stopping piece blocks the brake piece, the brake piece is in a clamped and stopped state, so the lock can not be opened through the brake piece; when a lock tongue is rotated by a key in a locking state, the brake piece can not work still owing to the push and the support from the arresting stop rod to the latch stop piece; the lock device can be also opened by rotating a handle or pressing the handle downwards.

Description

A kind of latch operating structure of door lock

The utility model relates to mechanical, particularly a kind of latch operating structure of door lock.

General door lock is when unlocked state, normally can it be opened by the drive of handle, and common door lock handle is to be divided into rotary type and press-down type, because both can't be general, therefore when producing, consider two kinds of patterns simultaneously, not only increase manufacturing cost, and cause warehousing pressure, thereby cause the increase of manufacturing cost, and influence economic benefit.

The purpose of this utility model is exactly the shortcoming that exists at above-mentioned general door lock, a kind of latch operating structure of door lock is provided, make door lock can be applicable to rotary type handle and press-down type handle simultaneously, reduce quantity in stock, be convenient to production and selling, increase economic efficiency greatly.

Technical solutions of the utility model:

According to the purpose of this utility model, a kind of latch operating structure of door lock is provided, mainly be to put a brake(-holder) block at the rotary axle box of the handle of door lock, make this brake(-holder) block be connected in locking bolt, and establish respectively to present in a side of this brake(-holder) block, the bolt stopping sheet of following arrangement and unplugging sheet, make between this bolt stopping sheet and unplugging sheet and be connected with a double-action plate, when normality, the door lock bottom constitutes unlocking condition to holding to drive locking bolt of brake(-holder) block, and when ending bolt sheet backstop in brake(-holder) block, then make brake(-holder) block be card and end state and can't unblank, make door lock can be applicable to rotary type handle and press-down type handle simultaneously by brake(-holder) block; In addition end the bolt sheet above, be provided with the gear-stopping bar that a top is placed in the dead bolt fore-set, make dead bolt via key turns during locking, this gear-stopping bar is able to promotion because of fore-set and constitutes the holding of bolt sheet, and brake(-holder) block can't be acted on, to keep the normally sealed of door lock.

Accompanying drawings structure of the present utility model and embodiment:

Fig. 1 is a perspective exploded view of the present utility model.

Fig. 2 is a combination schematic diagram of the present utility model.

Fig. 3 is the unlatching schematic diagram that holds of the present utility model.

Fig. 4 makes schematic diagram for bolt stop of the present utility model.

Fig. 5 is a dead bolt of the present utility model backstop view when closed.

(1) be that dead bolt, (11) are that brake(-holder) block, (41) for breach, (5) for bolt stopping sheet, (51) for button, (6) for unplugging sheet, (61) be button, (7) for double-action plate, (71) for dead bolt, (72) for spring, (8) for gear-stopping bar, (81) be centre bore, (82) be fulcrum for locking bolt, (3) for turning cylinder, (4) for door lock, (2) for fore-set, (100).

Shown in accompanying drawing 1 and accompanying drawing 3, the utility model is by dead bolt (1), locking bolt (2), turning cylinder (3), institute's structures such as brake(-holder) block (4), bolt stopping sheet (5), unplugging sheet (6), double-action plate (7), gear-stopping bar (8) Become, wherein a brake(-holder) block (4) is placed on the handle turning cylinder (3) of door lock (100), and at turning cylinder (3) top is provided with arcuation breach (41), is provided with the bolt that goes to upper and lower arrangement in a side of brake(-holder) block (4) End sheet (5) and unplugging sheet (6), establish respectively to be exposed to door at an end of bolt stopping sheet (5) and unplugging sheet (6) Lock button (51), (61) of (100), and establish with a double-action plate (7) in the central authorities of two elements, make this company After moving plate (7) is sleeved on a fixed leg (71), be embedded with a spring (72), make two of this spring (72) End is individually fixed in door lock (100) casing and unplugging sheet (6), and forms this bolt stopping sheet (5) and unplugging sheet (6) reverse linkage state; The top of bolt stopping sheet (5) is provided with a gear-stopping bar (8) that bends continuously, After making the centre bore (81) of gear-stopping bar (8) be placed on a fulcrum (82), its top is placed in dead bolt (1), Make dead bolt (1) when mobile, consist of gear-stopping bar by the fore-set of being located at dead bolt (1) (11) holds it (8) swing; When normality, dead bolt (1) is not sealed, and bolt stopping sheet (5) is emergence outwards, by door lock (100) below is held brake(-holder) block (4), returns door lock (100) inside to drive locking bolt (2), reaches Purpose to opening makes door lock (100) applicable to rotary type handle and press-down type handle.

Shown in accompanying drawing 4 and accompanying drawing 5, embodiment of the present utility model is as follows:

When the user enters within doors, can be with inwardly pressing of bolt stopping sheet (5), to drive outwards emergence of unplugging sheet (6), this bolt stopping sheet (5) is flat on the top of the breach (41) of brake(-holder) block (4) simultaneously, so, when press-down type handle or the start of rotary type handle, brake(-holder) block (4) will can't rotate because of the backstop of bolt stopping sheet (5), relatively can't be with locking bolt (2) pulling, to constitute the purpose of locking; When the user goes out, then can dead bolt (1) be produced outside the door lock (100) key, make it be locking states, while is because of the promotion of fore-set (11), make gear-stopping bar (8) its bottom is held in bolt stopping sheet (5) because of swing, so, this bolt stopping sheet (5) promptly can't be moved by pushing of unplugging sheet (6), and brake(-holder) block (4) therefore can't be opened locking bolt (2) by the drive of handle.
