Abstract

The utility model provides an iron connector for a hand shank of a lock. The iron connector is provided with a waist portion, a big end and a small end. The small end is in an irregular rhombus shape. The big end is in an elliptic cylinder shape. The side face corresponding to the short diameter of the elliptic cylinder is provided with planes and tapered planes. The planes are arranged on the upper portion of the big end. The lower ends of the planes are connected with the tapered planes. The tapered planes extend to the junction between the big end and the waist portion. A protrusion is arranged on the planes. The connector is connected with a directional piece. The iron connector is easy and convenient to produce and saves cost.

Description

Lock handle handle iron connector

Technical field

The utility model relates to a kind of lock handle handle iron connector.

Background technology

The connection mode of conventional bearing circle is in iron connector upper end, to have corresponding mouth in the market, on the correspondence position of bearing circle, be designed with tabs, during use, tabs is snapped in the opening of iron connector, bearing circle and iron connector are fixed, this design is because the tabs of bearing circle is thinner, and stress point is entirely in tabs, and bearing surface is little relatively, is easy to deformed damaged in use.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of processing simple, the connector that product tolerance is good.The technical scheme that realizes above-mentioned purpose is as follows:

Lock handle handle iron connector, it is characterized in that: described lock handle handle iron connector has three parts, be divided into waist, major part, microcephaly, microcephaly is fitfull rhombus, and major part is shaped as elliptical cylinder shape, and the short diametric(al) of elliptical cylinder shape is provided with plane and angular plane surface on corresponding side, plane layout is on the top of major part, the lower end of plane connects angular plane surface, and described angular plane surface extends to major part and waist junction, is provided with protrusion in plane.

Further, described protrusion is rhombus.

Further, also comprise direction sheet, the centre of direction sheet has hole, the both sides of hole symmetry have groove one, and the interior clamping of groove one is protruded, and the shape of groove one, size and protrusion are adaptive, the hole of direction sheet is connected on angular plane surface, the hole of direction sheet and the shape of access section, size adaptation.

Further, also have groove two on major part, groove two is arranged on the top of major part.

Further, also comprise handle, have handle hole on handle, the microcephaly of lock handle handle iron connector inserts in handle hole, and little head shapes and handle hole are adaptive.

Easier in the utility model production process, cost-saving.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail.

In figure, lock handle handle iron connector is connected with handle, on handle, there is handle hole, lock handle handle iron connector has three parts, be divided into major part 1, waist 2, microcephaly 3, the size of waist 2 is greater than major part 1, microcephaly 3 size, microcephaly is shaped as fitfull rhombus, microcephaly inserts handle hole and is connected with lock handle handle iron connector, little head shapes and handle hole are adaptive, major part is shaped as elliptical cylinder shape, the short diametric(al) of elliptical cylinder shape is provided with plane 4 and angular plane surface 9 on corresponding side, plane layout is on the top of major part, the lower end of plane connects angular plane surface, described angular plane surface extends to major part and waist junction, in plane 4, be provided with and protrude 5, protrude 5 the rhombus that is shaped as, on major part, also there is groove 26, groove two can be connected to the utility model on other parts.

The centre of direction sheet has hole 7, and the both sides of hole symmetry have groove 1, and the hole of direction sheet is connected on angular plane surface, the hole of direction sheet and the shape of access section, size adaptation, and the interior clamping of groove one is protruded, the shape of groove one and protrusion 5 adaptations.

During use, direction sheet is inserted on iron connector angular plane surface, the groove one on direction sheet interlocks with the rhombus of iron connector projection, during rotation, its application force is on whole direction sheet, increased the durability of product, iron connector is easier in process of production, cost-saving simultaneously.

These are only the preferred embodiment of the utility model embodiment; not in order to limit the utility model embodiment; all within the spirit and principle of the utility model embodiment; any modification of doing, be equal to replacement, improvement etc., all should be included in the protection domain of the utility model embodiment.
