Abstract

The utility model relates to a driving device for arc elevator doors, which is characterized in that two separated connecting rods are arranged above a rotary synchronous cog belt driven by a motor; one end of the connecting rods are connected with the inner door panels of the arc elevator door, and the other end of the connecting rods are respectively connected with one end of two V-shaped joints; the other end of the joints are movably pivoted; two U-shaped frame components arranged at the inner sides in relative opposite directions of the synchronous cog belt are arranged on the sliding seat of a preinstalled guide; the upper ends of the U-shaped frame components are movably connected with the elongated slotted holes of the two separated connecting rods to drive the two connecting rods to arc swing in arc to open and close the inner door panels. The utility model has the advantages that: by adopting the structure, the utility model is particularly suitable for the opening and the closing of arc elevator doors, and the opening and the closing of the arc elevator doors are more smooth and stable.

Description

The circular arc elevator door driving device

Technical field

The utility model relates to a kind of actuating device of circular arc elevator door, and You Zhiqi is used in the unlatching or the shutoff control unit of circular arc elevator door.

Background technology

Existing elevator door is opened door-plate after arriving the setting floor automatically, for personnel's turnover, after personnel enter elevator, automatically door-plate cuts out again.When floor is set in the elevator no show, then remain and close by the elevator door that interior external door constituted.

Existing elevator door major part all belongs to plane formula, that is elevator door is opened or closing movement is the linear reciprocation action.But specific buildings based on moulding or attractive in appearance on consideration, if elevator door is made as circular arc, driving route of external door panel can curved action route in it, so that traditional line motion elevator door driving device promptly is difficult to definite being suitable for.

Summary of the invention

The purpose of this utility model is to provide a kind of circular arc elevator door driving device that is used for the unlatching of circular arc elevator door or closes.

In order to achieve the above object, the utility model provides a kind of circular arc elevator door driving device, and it is provided with two connecting rods that separate, and makes this connecting rod be cross-placed on the top of a synchronous cog belt; This connecting rod one termination is closed the two separately internal hilar plates of interlock in the circular arc elevator door, and makes its other end be engaged in the two V-shaped ends that articular sclerite is set respectively, and this articular sclerite other end is in addition superimposed pivot joint then; Two reverse U-shaped frameworks then are located at not in the same way inboard of above-mentioned synchronous cog belt respectively, make its upper end can be engaged in the default long slot bore of two connecting rods with bearing; When complying with above-mentioned synchronous cog belt with motor drives, two reverse U-shaped frameworks and top connecting rod thereof will drive internal hilar plate and the external door panel arc is opened or closed.

The utility model has the advantages that:, and make the switching of circular arc elevator door more smooth and easy and stable because the utility model adopts such scheme, thereby is particularly suitable for being used in the opening and closing of circular arc elevator door.

Description of drawings

Below in conjunction with drawings and Examples the utility model is elaborated:

Fig. 1 is the constructional drawing of the utility model preferred embodiment;

Fig. 2 is that Fig. 1 is assembled in the close the door birds-eye view of state of internal hilar plate and relevant external door panel thereof;

Fig. 3 is the door opening state figure as Fig. 2;

Fig. 4 is Fig. 2 connecting rod part sectional view;

Fig. 5 is the front view that Fig. 2 does not contain external door panel;

Fig. 6 is the lateral plan of Fig. 5; And

Fig. 7 is the partial enlarged drawing of Fig. 6.

The specific embodiment

At first see also Fig. 1,4,6, the utility model roughly is provided with two separately and make the one termination close the same shape connecting rod 10 of interlock internal hilar plate, this connecting rod 10 is provided with hanging wheel 12 respectively in an end bent sheet 11, its other end 13 then respectively interlocking articulate an end of articular sclerite 20 in two V-arrangements, these articular sclerite 20 1 ends open with gradient, for the other end 13 of the above-mentioned connecting rod 10 of interlocking respectively, then superimposed and movable pivot joint the in addition of the other end 21 of articular sclerite 20.

In above-mentioned two the body of rod appropriate locations long slot bore 14 is set respectively then, supplies respectively at engage bearings 15 in this long slot bore 14 with shape connecting rod 10.This bearing 15 makes up with fulcrum 16 (consulting Fig. 4) respectively, and be positioned the below two relative reverse side U-shaped frameworks 17 the upper end flanging, 17 of whole U-shaped frameworks can be distinguished interlocking on slide 60, and make this slide 60 sliding default horizontal slide rails 61 of elevator end face that are assigned in.

Above-mentioned two reverse U-shaped frameworks 17 are located among the synchronous cog belt 30, and make two connecting rods 10 be cross-placed on synchronous cog belt 30 tops.This synchronous cog belt 30 is set around the

belt pulley

31,32 of two distance of separations location, and passes through a wherein belt pulley 31 drive whole piece synchronous cog belts 30 with an electrical motor 33.And an above-mentioned wherein U-shaped framework 17 with an intermediate plate 18 (consulting Fig. 4) folder due to synchronous cog belt 30 1 inside faces, 17 of another U-shaped frameworks with another intermediate plate 18 folders due to another opposite inner face (consulting Fig. 7).

Shown in Fig. 2,5, the utility model is complied with above-mentioned connecting rod 10 1 ends thereby can be engaged the internal hilar plate 40 of interlock both sides, when normality, this internal hilar plate 40 is closed together with relative external door panel 50.And be subjected to the driving control of electrical motor 33 and when mobile when synchronous cog belt 30, two reverse U-shaped frameworks 17 will be by top bearing 15 interlocks two connecting rods 10, making two connecting rods 10 is the center with the other end 21 of articular sclerite 20, and cooperate default door track 41 to produce the inverse-arc shape displacement, in this displacement process, can external door panel 50 be opened (as shown in Figure 3) synchronously by the default follower of internal hilar plate 40 42,43.When electrical motor 33 backward rotation, promptly can will should interior external door panel 40,50 close (consulting Fig. 2) again.

The utility model thereby a kind of actuating device that is particularly suitable for being used in the circular arc elevator door is provided makes the switching of circular arc elevator door more smooth and easy and stable, true value on the tool industry, and spy's mere formality in accordance with the law proposes utility application.
