Abstract
The utility model discloses a safety door heat plate. The safety door heat plate comprises a transverse structural steel plate and a longitudinal L-shaped structural steel plate, wherein the longitudinal L-shaped structural steel plate is arranged at one end of the transverse structural steel plate; the transverse structural steel plate is provided with a groove close to the middle position; the groove has a convex symmetric structure, and the two bottom corners of the convex groove has arc angle structures. The original bending single-arc-angle process is eliminated, double arc angles are molded at one time by adopting section steel cold drawing, wheels can be rolled on both sides to compress tightly in order to prevent a hanging plate from jumping out due to looseness, and an elevator door runs more reliably and silently.
Description
Technical field
The utility model relates to elevator component, is 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.
Utility model content
The purpose of this utility model 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.
The technical solution of the utility model 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.
In preferred embodiment of the utility model, the radius of the external diameter of described arc chord angle is 5mm.
In preferred embodiment of the utility model, the width of described convex groove is 40mm.
In preferred embodiment of the utility model, 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 preferred embodiment of the utility model, the height of a described safety-type door plate is 58mm.
Described in the utility model 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.
Brief description of the drawings
Fig. 1 is the structural representation in one preferred embodiment of the utility model safety-type door plate;
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.
Detailed description of the invention
Below preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Described in the utility model 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.
Described in the utility model 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 detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the utility model; the variation that can expect without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
