Heavy type balance weight door and window

Abstract

The invention relates to the field of door and window profiles, and particularly discloses a heavy type balance weight door and window. The heavy type balance weight door and window comprises a window sash frame and is characterized by further comprising a double-end stepping motor and first fixed pulleys; transmission rods are connected to the two ends of the double-end stepping motor, the torsion output end of each transmission rod is connected with a 90-degree right-angle planetary reducer, and the output end of the 90-degree right-angle planetary reducer is connected with a lead screw linear assembly; the first fixed pulleys are arranged on the two sides of the window sash frame respectively, each first fixed pulley is provided with a lifting traction rope, one end of each first lifting traction rope is connected with the window sash frame, the other end of each first lifting traction rope is connected with a balance weight, and a force distribution spring set is arranged at the bottom of the window sash frame. The heavy type balance weight door and window is simple and compact in structure, convenient to use and maintain, high in transmission efficiency and capable of better compensating, reducing and balancing the counter weight of a heavy window sash.

Description

technical field [0001] The invention relates to the field of door and window profiles, in particular to a heavy-duty balanced counterweight door and window. Background technique [0002] Due to the large volume and weight of the glass of the sightseeing balcony, the current movable column of the sliding window cannot provide enough supporting force, so that the balcony is usually sealed with fixed glass, and another window is opened on the glass; or Multiple pieces of small glass are used to seal the balcony, but the scheme of using multiple pieces of small glass needs to set multiple moving columns in the balcony. Multiple moving columns divide the balcony landscape into several pieces, which affects the appearance and appreciation of the scenery outside the balcony. [0003] The glass curtain wall is also formed from a single huge piece of glass, which cannot be opened and closed as a whole, or needs to be divided into multiple small pieces of glass, which will affect the ...

AI Technical Summary

Problems solved by technology

[0002] Due to the large volume and weight of the glass of the sightseeing balcony, the movable columns of the current lifting windows cannot provide enough supporting force, which leads to the current use of fixed glass to seal the balcony and open another window on the glass; or Use multiple pieces of small glass to seal the balcony, but the scheme of using multiple pieces of small glass needs to set up multiple moving columns in the balcony. Multiple moving columns will divide the balcony landscape into several pieces, which will affect the beauty and enjoy the scenery outside the balcony.

[0003] The glass curtain wall is also formed by a huge piece of glass, which also faces the problem that it cannot be opened and closed by lifting as a whole, or it needs to be divided into multiple small pieces of glass, which will affect the landscape.

[0004] At the same time, with the development of technology, the opening and closing of doors and windows can be automatically lifted. The traditional door and window lifting transmission structure usually uses a double-headed motor and a runner connected to the double-headed motor. To realize the lifting of doors and windows, because the stability of the wheel lifting structure is usually not good enough after long-term use, maintenance is relatively troublesome, and the transmission efficiency is not high enough
