AI Technical Summary

Technical Problem

The existing sash counterweight blocks have discreteness and insufficient matching, which leads to inaccurate counterweights, which increases the company's stocking cost, and has the problem of large counterweight errors.

Method used

A sash weight module is designed, including support profiles, support frames, bottom plates, top plates, pull plates and guide wheel components. A multiple receiving chambers are provided in the support frame, and counterweight blocks are provided in the receiving chamber. The counterweight blocks include lead blocks and weight adjustment blocks. Through the design of guide wheel components and limit slots/limit blocks, the support frame can be adjusted in shape and weight to meet the weight needs of different window sashes.

Benefits of technology

It realizes flexible adjustment of the weight of the window sash, reduces the weight of the window sash, makes it easy to open and close, reduces counterweight errors, reduces the production costs of the enterprise, and improves the accuracy and aesthetics of the counterweight.

Abstract

The present invention discloses a window sash counterweight module, including a supporting profile, a supporting frame, a bottom plate, a top plate, a pull plate and a guide wheel assembly. The supporting profile is provided with a supporting frame, a plurality of accommodating cavities are provided in the supporting frame, a counterweight block is provided in the accommodating cavity, a bottom plate adapted to its contour is provided at the bottom of the supporting frame, a top plate adapted to its contour is provided at the top of the supporting frame, a pull plate which passes through the top plate, the supporting frame and the bottom plate in sequence is vertically provided in the middle above the top plate, a connecting hole is processed on the pull plate above the top plate, and a plurality of guide wheel assemblies which are in contact with the inner wall of the supporting profile are installed on each side wall of the upper and lower parts of the supporting frame. The present invention can make the supporting frame itself carry weight by arranging the supporting frame in the supporting profile and arranging the counterweight block in the supporting frame, so as to achieve the purpose of counterweighting the window sash. In addition, through the guide wheel assembly, the supporting frame can slide smoothly in the supporting profile, and the wear of the supporting frame can be reduced, and the noise generated when the supporting frame moves can be reduced.
