Description

Technical Field

[0001] The utility model relates to building door and window components, and is a PVC sunshade louver. Background Art

[0002] At present, the total urban building area in China is about 50 billion square meters. The building energy consumption in China has accounted for 27.5% of the total terminal energy consumption of the whole society, with huge energy consumption. The largest proportion of building energy consumption is for doors and windows. The area of doors and windows accounts for less than 20% of the residential enclosure area, and the energy consumption can account for 40%-50% of the building energy consumption. To reduce building energy consumption, it is necessary to first take energy-saving measures for doors and windows.

[0003] At present, the sunshade method for building exterior windows in summer is to use curtains and louver roller blinds indoors to block sunlight. Although the sunlight is blocked, the heat generated by the exterior windows, window sills, and curtains irradiated by sunlight still enters the room, affecting the indoor temperature and thus increasing the energy consumption for indoor cooling. Summary of the Invention

[0004] In order to overcome the deficiencies in the sunshade measures for building exterior windows in summer, the utility model provides an outdoor vertically rotatable and slidable hollow PVC louver.

[0005] The technical solution adopted by the utility model to solve its technical problems is: an outdoor vertically rotatable and slidable hollow PVC louver includes an upper frame, a lower frame, PVC hollow louver blades, an upper rotating shaft, a lower rotating shaft, a pulley car, an insertion handle rod, a guide wire, and a guide wire bolt shaft component.

[0006] The frame is made of PVC profiles and is provided with an upper opening inner cavity groove track.

[0007] The PVC hollow louver blades are of a wide plate hollow structure, and its cross-section has a large central circular hole, two small side circular holes, and two middle medium circular holes.

[0008] The upper rotating shaft is made of stainless steel and is composed of a shaft rod and a shaft sleeve.

[0009] The lower rotating shaft is made of stainless steel and is composed of a shaft rod, a shaft sleeve, and a spring.

[0010] The pulley car is made of stainless steel and is composed of a pulley and an axle.

[0011] The insertion handle rod is made of stainless steel.

[0012] The guide wire is a nylon cord.

[0013] The guide wire bolt shaft is made of stainless steel.

[0014] This hollow PVC louver is installed on the outer side of the building's exterior window. It is equipped with upper and lower track frames with built-in cavity grooves. Trolleys are installed in the upper and lower cavity grooves. The louver blades are wide plate-shaped hollow PVC louver blades, which are arranged vertically. The hollow structure of the PVC louver blades can reduce the heat energy generated on the outer side of the PVC louver blades due to sunlight irradiation from radiating and conducting to the building's exterior window. The hollow channels of the PVC louver blades can generate airflows, accelerating the heat dissipation on the outer side of the PVC louver blades. A rotating shaft is installed in the upper and lower central cavities of the PVC hollow louver blades. The rotating shaft is connected to the trolley in the cavity groove by an insertion handle rod. Guide wire bolt shafts are installed in the upper cavity on both sides of the upper end of the PVC hollow louver blades. Guide wires are fixed on the guide wire bolt shafts at equal intervals. The PVC hollow louver blades are connected in series by the guide wires to form an outdoor sunshade louver, blocking the summer sunlight outside the building's exterior window, thereby reducing the energy consumption for indoor cooling in summer. By rotating any louver blade, other louver blades will rotate synchronously under the traction of the guide wire to adjust the sunlight irradiation amount. In autumn and winter, the louver blades can be slid and folded together and fixed on the side of the louver. This is an outdoor vertically rotatable and slidable hollow PVC louver.

[0015] An outdoor vertically rotatable and slidable hollow PVC louver, having an upper frame, a lower frame, PVC hollow louver blades, an upper rotating shaft, a lower rotating shaft, trolleys, insertion handle rods, guide wires, and guide wire bolt shaft components, is installed on the outer side of the building's exterior window. Trolleys are installed in the cavity grooves of the upper and lower frames. The louver blades are arranged vertically. The louver blades are of a hollow structure. Rotating shafts are installed in the cavities of the louver blades. The rotating shafts are connected to the trolleys by insertion handle rods. The louver blades are tractioned by the guide wires. By rotating the louver blades synchronously, the sunlight irradiation amount can be adjusted. The louver blades can be slid and folded together, which is convenient for use and storage, and can more effectively reduce the influence of summer sunlight on indoor heat radiation.
