Wind-resistance stabilizing gear seat of external sunshade curtain drawing system

Abstract

The invention provides a wind-resistance stabilizing gear seat of an external sunshade curtain drawing system. A rotating shaft is rotatably arranged in a seat body. A first gear is connected to the rotating shaft in a sleeving mode and used for meshing with a rack. A guide part is movably arranged in the seat body in the first direction parallel to the axis of the rotating shaft. A first elastic component is located between the seat body and one end of the guide part and abuts against the seat body and one end of the guide part. A second elastic component is located between the seat body and the other end of the guide part and abuts against the seat body and the other end of the guide part. A rack containing portion of the guide part is used for containing the rack after the first gear meshes with the rack so that the rack can be limited to move in the second direction parallel to the axis of the rotating shaft. According to the wind-resistance stabilizing gear seat of the external sunshade curtain drawing system, lateral wind influences can be reduced, so that the rack and the gear seat are unlikely to collide and are not prone to deformation, the service life of the external sunshade curtain drawing system is prolonged, and the wind-resistance stabilizing gear seat is ingenious in design, simple in structure, easy to manufacture, convenient to use and suitable for large-scale application and popularization.

Description

technical field [0001] The present invention relates to the technical field of an external sunshade curtain system, in particular to the technical field of a gear seat of an external sunshade curtain system, in particular to a wind-resistant and stable gear seat of an external sunshade curtain system. Background technique [0002] The external shading curtain system uses materials with a certain shading rate to block excess light, and plays the role of adjusting light, cooling or heat preservation, and is widely used in greenhouses. [0003] The external sunshade curtain system usually uses a rack and pinion device, which usually includes a geared motor, a gear seat, a rack and an external sunshade curtain. The gear seat includes a seat body, a rotating shaft and a gear. The rotating shaft is rotatably set in the seat body, and the gear socket On the rotating shaft (which can be integrally formed), the reduction motor is connected to the rotating shaft to drive the rotating ...

AI Technical Summary

Problems solved by technology

[0004] However, if the above-mentioned external sunshade curtain system is adopted, the external sunshade curtain is greatly affected by the lateral (along the axis direction of the rotating shaft) wind force, and the gear seat and the rack will bear a large force in the lateral direction, and the rack and the gear seat are easy to Collision, resulting in deformation of the rack and gear seat, affecting the life of the external sunshade curtain system
