Abstract

The utility model relates to a suspension mechanism for a lift-cabin door, which comprises a bottom plate, wherein the bottom plate is rectangular and is arranged transversely and externally provided with a guide rail. The guide rail is arranged transversely, two ends thereof are respectively and fixedly connected with those of the bottom plate, and a space is reserved between the guide rail and the bottom plate. The suspension mechanism is characterized in that the guide rail is formed by bending of a rectangular steel plate, namely the lower edge of the rectangular steel plate is bent outwards and upwards, as well as outwards and downwards by 90 degrees respectively, and a space is reserved between an outwards-bent line and an upwards-bent line as well as an outwards-bent line and a downwards-bent line respectively, thus forming the guide rail on the plate surface between the outwards-bent line and the downwards-bent line. The guide rail is provided with two roller wheels, the wheel shafts of which are fixed at two ends of the upper edge of a hanging plate in the installation state, and the lower edge of the hanging plate is connected with the upper edge of a lift-cabin door plate. The suspension mechanism for the lift-cabin door has relatively low manufacturing cost and is applicable to lifts of various buildings.

Description

The elevator door hitch

Technical field

The utility model relates to a kind of elevator door.Specifically, be the hitch that is used to hang door of elevator on the various buildings.

Background technology

At present, used elevator door hitch all is traditional hitch on the elevator of various buildings.This traditional hitch contains base plate and guide rail, and base plate wherein is an oblong, and guide rail is the oblong foundry goods.The width of guide rail is less than base plate, and the two ends of guide rail are fixed on the two ends of base plate respectively by fastener, and makes between guide rail and base plate and leave spacing, with the convenient roller of installing.Under the running condition, the top of door-plate links to each other with roller by link plate, roller wherein place on the guide rail and can be on guide rail side travel, thereby under actuating unit drives, realize closing and opening of elevator door.Because the guide rail of above-mentioned elevator door hitch is a foundry goods, thickness is thicker, needs to use steel more, makes productive costs higher.Because its guide rail is a foundry goods, need particular manufacturing craft in the manufacturing process again, like this, also can increase productive costs.

The utility model content

Problem to be solved in the utility model provides a kind of elevator door hitch.This elevator door hitch, manufacturing cost is lower.

For addressing the above problem, take following technical scheme:

Elevator door hitch of the present utility model contains base plate, and this base plate is an oblong, and it is lateral arrangement, and there is guide rail its outside.Described guide rail is lateral arrangement, its two ends be connected mutually with the two ends of base plate respectively and and base plate between leave spacing.Be characterized in that described guide rail is to form with the bending of oblong steel plate, it be bottom at the oblong steel plate outwards bend successively 90 degree, upwards bend 90 degree, more outwards bend 90 degree, bend 90 degree downwards, and outside folding line with upwards between folding line, more outwards folding line with all leave spacing between folding line downwards, thereby forming track on the plate face between outside folding line and the downward folding line again.Described track is provided with two rollers and a link plate, and two rollers wherein all place on the track, and two, top of link plate links to each other with the wheel shaft of a roller respectively, and the bottom of link plate links to each other with the door of elevator top under installing condition.Between base plate and the guide rail attaching parts is arranged, the upper and lower of attaching parts is connected mutually with the centre of base plate and guide rail respectively.

The further improvement of the utility model scheme is that the top of base plate has the outside flanging of 90 degree.

The further improvement of the utility model scheme is that the bottom of base plate has the outside flanging of 90 degree.

There is the outside flanging of 90 degree the top of further improvement project guide rail of the present utility model, and this outside flanging and interorbital leave the spacing that roller is installed.

Adopt such scheme, have the following advantages:

By such scheme as can be seen, since described guide rail is the bottom at the oblong steel plate outwards bend successively 90 degree, upwards bend 90 degree, more outwards bend 90 degree, bend 90 degree downwards, and outside folding line with upwards between folding line, more outwards folding line with all leave spacing between folding line downwards, thereby forming track on the plate face between outside folding line and the downward folding line again.Compare with the foundry goods in the background technology, not only can reduce its thickness, and do not need mould in the production process, thereby greatly reduce productive costs.

Description of drawings

Fig. 1 is an elevator door hitch scheme drawing of the present utility model;

Fig. 2 is the A-A cross-sectional schematic of Fig. 1.

The specific embodiment

As depicted in figs. 1 and 2, elevator door hitch of the present utility model contains base plate 1, and this base plate is an oblong, and it is lateral arrangement, and its top is fixed on the doorframe top of elevator door under installing condition.The outside of base plate 1 is provided with guide rail 3.Described guide rail 3 contains an oblong steel plate, and this oblong steel plate is lateral arrangement, and each is fixed on the two ends of base plate 1 by a flute profile pad spare 7 and bolt 8 its two ends, makes itself and 1 of base plate leave spacing.The bottom of oblong steel plate outwards bend successively 90 the degree, upwards bend 90 the degree, more outwards bend 90 the degree, downwards bend 90 the degree, and outside folding line with upwards between folding line, more outwards folding line with all leave spacing between folding line downwards, thereby forming track on the plate face between outside folding line and the downward folding line again.Described track is provided with two rollers 4 and a link plate 6, and two rollers 4 wherein all place on the track, and two, top of link plate 6 links to each other with the wheel shaft 5 of a roller 4 respectively, and the bottom of link plate 6 links to each other with the door of elevator top under installing condition.Drive the door of elevator sway by roller 4 and link plate 6, realize opening and closing of door of elevator with this.

Be to strengthen the intensity of base plate 1, all be processed with the outside flanging of 90 degree at the bottom and upper segment of base plate 1.

For strengthening the intensity of guide rail 3, be processed with the outside flanging of 90 degree in the top of guide rail 3, the interorbital of this outside flanging and guide rail leaves the spacing that roller 4 is installed.

For improving the intensity of guide rail 3, between base plate 1 and guide rail 3, be provided with attaching parts 2, the top of this attaching parts is by the top that is bolted to base plate 1.The outside, bottom of attaching parts 2 is processed with hook, and this hook catches on the upper edge of guide rail 3.
