Description

Adjustable universal connecting piece assembly for top parts of two sides of outer casing of curtain driver

Technical Field

The utility model relates to a technical field that the (window) curtain automatic drive opened and shut specifically is general connecting piece assembly with adjustable (window) curtain driver outer casing both sides top.

Background

The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.

There are three types of curtain rails available on the market, one type is straight-grooved rail, one type is i-shaped rail, and one type is roman rod rail (cylindrical rail), and the applicant's first generation products have applied for a plurality of patents in October 2020 and October 2020, such as "hook (T-shaped)" with application number CN202030612405.7 (for straight-grooved rail), "hook on curtain driver with application number CN202022293624.0 for i-shaped curtain rail" (for i-shaped rail), and "curtain driver side cover connector for roman rod curtain rail" (for roman rod rail) with application number CN 2020225893.7. Three curtain tracks in a generation of products need 3 side cover connecting pieces, namely a straight groove track side cover connecting piece, an I-shaped track side cover connecting piece and a Roman rod track side cover connecting piece as shown in the attached figure 11 of the specification. As shown in the attached figure 12 of the specification, the I-shaped rail side cover connecting piece is taken as an example and is detachably arranged on two sides of a curtain driver shell according to the mode shown in the figure.

However, this generation of products gets feedback with the following disadvantages:

firstly, because the sizes of straight groove rails, I-shaped rails and Roman rod rails (cylindrical rails) on the market are different and are influenced by the processing quality of different curtain rail manufacturers, the straight groove rails, the I-shaped rails and the Roman rod rails (cylindrical rails) are almost not unified, after 3 side cover connecting pieces in a first generation product are used on the rails of different curtain rail manufacturers, the matching degree is different, the product is not smooth in use, and a curtain driver product which can be matched with an original curtain rail sliding piece and is carried by the curtain rail manufacturers can be preferably designed.

Secondly, for straight grooved rails with different thicknesses on the bottom surface, I-shaped rails and Roman rod rails (cylindrical rails) with different diameters, side cover connecting pieces in a product of the first generation can only be adjusted through the elastic force of an internal spring, and because the deformation of the spring is different, the friction force caused by the elastic force of the spring between a driving wheel and a contact surface is different, so that the smoothness of the product in the using process is influenced, the friction force is too small, and the load caused by the dead weight of the curtain is very large, and the curtain can slip.

Third, a generation product need set up detachable side cap connecting piece, and the structural design cost of complete machine and manufacturing cost are bigger, if whole (window) curtain driver designs the integral type, just can greatly reduced cost, and it is more convenient to use moreover, has avoided loaded down with trivial details dismouting work, has also avoided the product damage that dismouting work brought.
