Pulling rope tensioning device of hollow glass with built-in shutter

Abstract

The invention provides a pulling rope tensioning device of hollow glass with a built-in shutter, and belongs to the technical field of hollow glass products. The pulling rope tightening device of hollow glass with the built-in shutter comprises a spring rod seat, a spring rod, a tensioning spring, a pulling rope sliding wheel seat and a pulling rope sliding wheel. The upper end of the spring rod seat is folded horizontally with a spring rod folding plate, wherein a spring rod hole is formed in the spring rod folding plate. The spring rod is inserted in the spring rod hole, the upper end ofthe spring rod is composed of a spring rod connecting head, the spring rod connecting head is located above the spring rod seat folding plate, and a spring supporting seat is arranged at the lower endof the spring rod. The spring rod is sleeved with the tensioning spring, wherein the upper end of the tensioning spring supports the lower side of the spring rod seat folding plate and the lower endof the tensioning spring is supports the spring supporting seat. The upper portion of the pulling rope sliding wheel seat is composed of a pulling rope sliding wheel cavity, the lower portion of the pulling rope is extended with a pair of hinged seats, and the hinged seats is connected with the spring rod connecting head in a hinged mode through a pin shaft of the hinged seat. The pulling rope sliding wheel is rotationally arranged in the pulling rope sliding wheel cavity through an oil tanker pin shaft. The turning of a curtain and the lifting effect of a shutter is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of hollow glass products, and in particular relates to a traction rope tensioning device for built-in shutters of hollow glass. Background technique [0002] The above-mentioned hollow glass built-in shutters have the following self-evident advantages: good heat insulation to reflect the energy saving of the building; excellent sound insulation to avoid the noise from the outside world; anti-condensation and frost to ensure indoor light Sufficient and reflect the desired bright effect; through the adjustment of the deflection angle of the venetian blinds, the required indoor lighting requirements can be obtained and the privacy can be protected, and the venetian blinds can be free from dust. Effect; it is ideal for embellishment of buildings to improve the grade of buildings; strong impact resistance, good safety and long service life to meet the installation requirements of high-rise buildings and meet the ...

AI Technical Summary

Problems solved by technology

Because in the assembling process of the venetian blind, the two ends of the curtain reversing traction rope are usually connected with the curtain reversing internal control mechanism which is used to control the reversing of the curtain and is arranged on the left side of the window by manual knotting, and Also manually knot the two ends of the venetian blind lifting traction rope to connect with the bottom bar of the venetian blind and the venetian blind lifting internal control mechanism which is used to control the lifting of the venetian blind and is set on the right side of the window, so that the venetian blinds are turned over The actual length of the traction rope and the lifting rope of the venetian blind is often more or less longer than the length required by the process design. Although the excess length is very limited, it will have a certain impact on the turning of the curtain and the lifting of the venetian blind

In addition, during daily use, the traction rope for turning over the curtain and the lifting and lowering of the venetian blind will elongate, which will also affect the turning over of the curtain and the lifting effect of the venetian blind
