Elevator door guide device

Abstract

The invention relates to the technical field of elevator parts, and discloses an elevator door guiding device which comprises a sliding body and a micro-seam sill strip, a strip groove with an upward opening is formed in the micro-seam sill strip, the sliding body comprises a box body, a compensation spring and a cross-shaped sliding block, a containing cavity with a downward opening is formed in the box body, and the cross-shaped sliding block is arranged in the containing cavity. The cross sliding block is detachably arranged in the box body, and one end of the cross sliding block extends downwards and is movably inserted into a strip groove in the micro-crack sill strip. Impact force is absorbed through the compensation spring, self-deformation is avoided by means of space displacement matching of the crosshead shoe, buffering is conducted through the compensation spring, and after the impact force is eliminated, the crosshead shoe is driven to return to the original position under the action of the compensation spring, so that the normal guiding sliding effect is guaranteed.

Description

technical field [0001] The invention relates to the technical field of elevator components, in particular to an elevator door guiding device. Background technique [0002] Elevator door guiding device is an annex in the elevator device, and the existing design of this field is as attached Figure 1-3 As shown, the sill, one of its accessories, is fixedly installed on the wall mechanism of the building, and another accessory, the slider, is fixed at the lower end of the elevator door. The slider is inserted into the sill for guiding, but does not bear The gravity of the elevator door facilitates the smooth opening and closing of the elevator door. However, due to the strength and installation error requirements of the existing guide device, on the one hand, there is a large gap in the upward opening door threshold.

[0002] Elevator door guiding device is an annex in the elevator device, and the existing design of this field is as attached Figure 1-3 As shown, the sill of one of its accessories is fixedly installed on the wall mechanism of the building, and another accessory-slider is fixed at the lower end of the elevator door. The slider is inserted into the sill for guiding, but does not bear The gravity of the elevator door facilitates the smooth opening and closing of the elevator door. However, due to the strength and installation error requirements of the existing guide device, on the one hand, there is a large gap in the door opening upward. When passengers hit the elevator door intentionally or unintentionally, it is inevitable It will lead to the deformation of the slider, which will also cause the elevator door to open and close poorly or even break and fail. There is a risk of jamming for people wearing high heels. In addition, since the slider is fixed on the elevator door by bolts, it is neglected in maintenance. In some cases, it is easy to loosen and cause poor sliding. In addition, due to the large upward opening gap, it is easy to accumulate sundries. Since the slider itself and the threshold are in a gap fit, the accumulation of sundries will also lead to poor opening and closing.
