Description

The metal door latch

Technical field:

The utility model relates to a kind of door bolt.

Background technology:

Existing metal door such as safety anti-theft door, the latch of copper skill door etc. all uses common latch with a kind of similar to this latch shape, but controls the latch that inserted link slides and locatees with profile of tooth.Preceding a kind of latch structure is common simple, not attractive in appearance, and a kind of latch in back uses dumb and feel that press is uncomfortable, to the old man, and child, the women uses very inconvenient.

Summary of the invention:

The inside that the utility model provides a kind of latch to be installed in the shop front, metal door latch simple in structure and easy for installation.

The utility model is achieved by the following technical solution: a kind of metal door latch, comprise panel, its major technique feature is to have the slotted eye that slides for spanner in the panel, the slotted eye two ends are circular hole, interlude is a rectangle, spanner inserts in the hole of inserted link by the circular hole of slotted eye, is provided with spring and cottor pin between spanner and the inserted link;

Described spanner the first half is a rectangle, the spanner hand by face be rectangle and with the contacted minor face of slotted eye circular hole be arc, spanner the latter half is a round bar;

Described inserted link is fixed on the support.

Characteristics of the present utility model: 1, latch is installed in the inside of the shop front, has increased the attractive in appearance of the shop front.2, the combination in the spanner of this latch and the hole of panel, utilized cleverly circle can 360 degree rotation and the rectangular length of side do not wait principle to control the slip and the location of latch inserted link.3, utilize the elasticity of spring to control the elasticity that this spanner wrench is connected with inserted link, make spanner and inserted link be connected with certain expansive force, prevent that spanner from arbitrarily rotating and the slip inserted link.This metal door bolt has reasonable in design, and is simple in structure, characteristics easy for installation, and bigger advantage is to use convenient, flexibly with safer.

Description of drawings:
