Counterweight connection device for double-layer insulating glass built-in shutters

Abstract

The invention discloses a balance weight connection device for a louver with built-in double-layer hollow glass, and belongs to the technical field of shading hollow glassware. The device comprises a pulling inner sliding block and a balance weight, and is characterized in that the lower part of the pulling inner sliding block in the height direction forms a balance weight transitional connection part insertion cavity; the bottom of the insertion cavity is communicated with the outside; a position corresponding to the insertion cavity is provided with a balance weight transitional connection part in an embedded manner; the top of the balance weight is fixed with the balance weight transitional connection part; and the upper parts of the left and right sides of the balance weight are in embedment fit with the balance weight transitional connection part. The device can enable the balance weight to be fixedly connected with the balance weight transitional connection part, cannot cause shaking and falling in a use process, improves the assembly effect, guarantees the assembly quality, represents a durable excellent use effect, and can guarantee that the louver is folded upwards in a use process, thereby avoiding abnormal falling.

Description

technical field [0001] The invention belongs to the technical field of sunshade hollow glass products, and in particular relates to a counterweight connecting device of a double-layer hollow glass built-in shutter. Background technique [0002] The double-layer hollow glass built-in blinds mentioned above refer to the construction of a venetian blind that can be raised and lowered as needed in two pieces of glass (inner glass and outer glass) that are arranged in a face-to-face state and that seal the surrounding edges. Windows that belong to the category of sunshade hollow glass products. This kind of window has the following self-evident advantages: good heat insulation, so as to reflect the energy saving of the building; excellent sound insulation, so as to avoid the disturbance of external noise; Expected bright effect; through the adjustment of the deflection angle of the venetian blinds, the required indoor lighting requirements can be obtained, privacy can be protect...

Problems solved by technology

Although this structure can solve the above-mentioned technical problems in an all-round way, it has the following deficiencies: one is that the binding connection between the counterweight 2 and the traction inner slider 1 has poor stability and reliability, and is prone to shaking or even falling off; Manually pass the iron wire 10 through the wire hole preset on the traction inner slider 1 and wind around the wire groove preset on the counterweight 2 and also need to twist the two ends of the wire to have a plurality of twists. Therefore, the assembly efficiency is low, and it is difficult to meet the requirements of industrialized mass production; the second is that the weight 2 is fixedly connected to the traction inner slider 1 through the iron wire 10 by hand, so the connection quality is difficult to guarantee, because the connection quality There is an inseparable causal relationship with the operator's experience, sense of responsibility, emotion and even physical fitness

[0008] CN200971738Y recommends "the louver in the hollow glass with improved structure" which is provided with grooves on the walls around the counterweight to form a groove inwardly, and a fixing bar is embedded in the groove, and the upper end of the fixing bar protrudes out of the counterweight. The upper part in the height direction is formed with a bending part, and the bending part is hung and matched with the hanging hole (patent called hole) opened at the lower part of the traction inner slider (for details, please refer to the 12th to 23rd lines on page 6 of the patent specification ), the patent solution is not enough to solve the aforementioned image 3 The structure is lacking and does not give the inspiration to solve the technical problems described
