Description

Technical Field

[0001] The utility model belongs to the technical field of insulating glass, and particularly relates to the lower beam of a louver insulating glass. Background Art

[0002] Insulating glass is a glass product in which two or more pieces of glass are evenly separated by effective supports and bonded and sealed around, so that a dry gas space is formed between the glass layers. The built-in louver insulating glass has the characteristics of good light shading and heat insulation, and is an important category of insulating glass. The lower beam of the louver is an important component on the louver curtain, which is used to straighten the louver curtain (i.e., keep it perpendicular to the ground) and assemble the pull rope assembly.

[0003] In actual use, the following technical problems exist in extra-large-sized louver windows: due to the extremely large size of the louver curtain, a relatively large number of groups of pull ropes will be set. The pull ropes themselves have a certain elasticity, which will pull the louver curtain to retract, resulting in the louver not being able to descend completely in place. At this time, it is necessary to increase the weight of the lower beam. Since the volume of the glass inner cavity is fixed, if the weight of the lower beam is increased, the first method: increasing the wall thickness, which will make the internal space of the inner cavity too small to install the pull rope assembly; the second method: manufacturing the lower beam with a material having a greater density, which will bring cost problems (such as using copper), or the material may not be suitable for making profiles (such as using lead).

[0004] Therefore, it is urgent to design a lower beam for an extra-large-sized louver insulating glass to solve the above technical problems. Summary of the Utility Model

[0005] In view of the above technical problems, the utility model provides a lower beam for an extra-large-sized louver insulating glass, which increases the weight of the lower beam of the louver while ensuring the inner cavity volume and controlling the manufacturing cost, so as to ensure the louver curtain.

One side of the upper plug body is fixed to the inner wall of the side cover below the upper plug body, and the other side of the upper plug body is arranged inside the counterweight cavity.

[0009] Preferably, the lower plug bodies on both sides are in close contact with both ends of the counterweight bar, so that the counterweight bar is centered.

[0025] Embodiment 1

[0026] Figures 1 to 4 It is the lower beam of the super-large-size louvered hollow glass, including the beam body 1 and the cover body 2. In this embodiment, the beam body 1 and the cover body 2 are detachably connected by a slideway fit. The beam body 1 is a hollow structure, and the bottom of the beam body 1 is V-shaped, so that a part of the beam body 1 can be embedded in the frame body to ensure the height of the inner cavity and increase the light transmission area of the louver curtain. A partition 11 is provided in the inner cavity of the beam body 1, and the partition 11 divides the inner cavity into an installation cavity 12 and a counterweight cavity 13. The installation cavity 12 is located in the upper part and is used to set the pull rope assembly 6. The pull rope assembly 6 is a conventional accessory, and its specific structure will not be described in detail. The counterweight cavity 13 is located in the lower part, and a counterweight bar 3 is provided in the counterweight cavity 13;

[0027] Detachable beam plugs 4 are provided on both sides of the beam body 1. The beam plug 4 includes a side cover 41, an upper plug body 42, and a lower plug body 43. Both the upper plug body 42 and the lower plug body 43 are made of flexible materials, such as rubber or polyurethane. One side of the upper plug body 43 is fixed to the inner wall of the side cover 41 and is adapted to the cross-sectional shape of the installation cavity 12. The other side of the upper plug body 43 is arranged in the installation cavity 12. One side of the lower plug body 43 is fixed to the inner wall of the side cover 41 below the upper plug body 43 and is adapted to the cross-sectional shape of the counterweight cavity 13. The other side of the lower plug body 43 is arranged in the counterweight cavity 13.

[0028] In this embodiment, opposed sliding grooves 21 are provided on the inner wall of the cover body 2. The sliding grooves 21 enable the upper plug body 42 to be better fitted.

[0029] When the beam plug 4 is installed in place, the lower plug bodies 43 on both sides are in close contact with the ends of the counterweight bar 3, so that the counterweight bar 3 is centered. This can ensure that the louver curtain remains balanced during the pulling process. The counterweight bar can be of a hollow structure, so that under the condition of ensuring an appropriate weight, the length meets the requirements.

[0030] By providing a counterweight cavity 13 and arranging a counterweight bar 3 therein, without reducing the internal volume, the weight of the lower beam is effectively increased, ensuring that the louver curtain will not retract. Moreover, the counterweight bar 3 is arranged in the counterweight cavity 13 and is effectively separated from the cable assembly 6, and will not shake during the lifting process to interfere with the operation of the cable assembly.

[0031] Embodiment 2

[0032] See Figure 5 , the difference from Embodiment 1 is that in this embodiment, the bottom of the counterweight bar 3 is a plane, and several threaded holes are provided on the side surface of the beam body 1 corresponding to this plane. Screws 5 are provided in the threaded holes. The inner end of the screw 5 is a plane, and a counterbore is also provided on the bottom plane of the counterweight bar 3. The inner end of the screw 5 is arranged in the counterbore, and the inner end of the screw 5 is in close contact with the plane of the counterweight bar 3, so that the counterweight bar 3 is in close contact with the inner wall of the counterweight cavity 13.

[0033] The inner wall of the counterweight cavity 13 is provided with sliding strips 131, and the counterweight bar 3 is provided with sliding grooves matching the sliding strips 13. Such a setting plays a role in positioning the counterweight bar 3.

[0034] After installing the beam plug 4, screws 5 are inserted into the threaded holes, and the counterweight bar 3 is reliably fixed in the counterweight cavity 13 through the screws 5, further preventing the counterweight bar 3 from generating abnormal noises during the lifting of the louver curtain.

[0035] The present utility model is not limited to the above embodiments. Based on the technical solutions disclosed in the present utility model, those skilled in the art can, according to the disclosed technical content, make some substitutions and deformations of some technical features without creative labor, and these substitutions and deformations are all within the protection scope of the present utility model.
