Abstract
The invention discloses a safe door head plate which comprises a transverse structure steel plate and a longitudinal L-type structure steel plate. The longitudinal L-type structure steel plate is arranged at one end of the transverse structure steel plate, a groove is formed in the position close to the middle of the transverse structure steel plate, the groove is of a convex symmetrical structure, two base angles of the convex groove are of an arc angle structure, and the safe door head plate is formed by cold-drawing section steel through a one-time forming process. An original bending single-arc-angle process is eliminated, dual arc angles are formed at one time by cold-drawing the section steel, wheels can roll on the two sides, compression is carried out, a hanging plate cannot be loosened or bounce out, and an elevator door operates more reliably and more silently.
Description
Technical field
The present invention relates to elevator component, be specifically related to an a kind of safety-type door plate.
Background technology
Traditional elevator door head plate is that angle bender bending forms, and only has the arc chord angle link plate wheel that is used for rolling.Owing to only having an arc chord angle to be used for rolling and fixing wheel, in elevator switch door vibrations process, wheel may be jumped out, and causes elevator door switch to lose efficacy, and likely causes safety misadventure.Angle bender is made needs multiple tracks bending operation, wastes time and energy.
Summary of the invention
The object of the present invention is to provide the cold drawn one-shot forming of a kind of shaped steel, two arc chord angle, a reliable quietly safety-type door plate.
Technical scheme of the present invention is, an a kind of safety-type door plate, comprise transversary steel plate and longitudinal L-type structural steel and iron, described longitudinal L-type structural steel and iron is arranged at one end of transversary steel plate, described transversary steel plate is provided with a groove near midway location, described groove is a convex symmetrical structure, and two base angles of described convex groove are arc chord angle structure, and a described safety-type door plate is made up of the cold drawn one-shot forming technique of shaped steel.
In a preferred embodiment of the present invention, the radius of the external diameter of described arc chord angle is 5mm.
In a preferred embodiment of the present invention, the width of described convex groove is 40mm.
In a preferred embodiment of the present invention, the width that a described safety-type door plate is removed the transverse distance of longitudinal L-type structural steel and iron is 169mm.
In a preferred embodiment of the present invention, the height of a described safety-type door plate is 58mm.
Of the present invention is an a kind of safety-type door plate, has cancelled former bending list arc chord angle technique, adopts the two arc chord angles of the cold drawn one-shot forming of shaped steel, wheel can roll on both sides, suppressing tightly, link plate can not become flexible and jump out again, and elevator door operation is more reliable quiet.
Accompanying drawing explanation
Fig. 1 is the structural representation in a safety-type door plate of the present invention one preferred embodiment;
In accompanying drawing, each mark is as follows: 1, transversary steel plate, 2, longitudinal L-type structural steel and iron, 3, groove, 4, arc chord angle.
The specific embodiment
Below preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Of the present invention is an a kind of safety-type door plate, shown in Figure 1, comprise transversary steel plate 1 and longitudinal L-type structural steel and iron 2, described longitudinal L-type structural steel and iron 2 is arranged at one end of transversary steel plate 1, described transversary steel plate 1 is provided with a groove 3 near midway location, described groove 3 is a convex symmetrical structure, and two base angles of described convex groove 3 are arc chord angle 4 structures, and a described safety-type door plate is made up of the cold drawn one-shot forming technique of shaped steel.
The radius of the external diameter of described arc chord angle 4 is 5mm.
The width of described convex groove 3 is 40mm.
The width that a described safety-type door plate is removed the transverse distance of longitudinal L-type structural steel and iron 2 is 169mm.
The height of a described safety-type door plate is 58mm.
In process of production, directly by machine up, steel plate is made to a safety-type door plate by the cold drawn one-shot forming processing of shaped steel.
Of the present invention is an a kind of safety-type door plate, has cancelled former bending list arc chord angle technique, adopts the two arc chord angles of the cold drawn one-shot forming of shaped steel, wheel can roll on both sides, suppressing tightly, link plate can not become flexible and jump out again, and elevator door operation is more reliable quiet.
The foregoing is only the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; the variation that can expect without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
