[0001] This utility model relates to the field of louver technology, and in particular to a PVC co-extruded louver profile. Background Technology

[0002] Currently, there are many types of blinds on the market. Blinds are generally made of materials such as wood, glass, and aluminum alloy. They can not only block sunlight and adjust light, but also blend into the style of home decoration to form a beautiful decorative effect.

[0003] With the development of technology, PVC blinds can also meet the above requirements. However, if the blind components come into direct contact with water or are exposed to high temperature and humidity during use, they are prone to cracking and deformation. They have poor corrosion resistance and are easily damaged under external force, which will cause the blinds to be unusable. Utility Model Content

[0004] The purpose of this utility model is to provide a PVC co-extruded louver profile. The UV-resistant layer can prevent the material from degrading due to light, while the heat-reflective layer can reduce heat transfer, achieving dual energy saving of sun protection and heat insulation. This solves the problems of high energy consumption and easy deformation of traditional louvers in high-temperature environments.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PVC co-extruded louver profile, comprising a main body, mounting brackets on both sides of the lower end of the main body, an adjustment mechanism inside the mounting bracket, the adjustment mechanism comprising a gear, a strip plate, and a transmission rack, a movable groove inside the mounting bracket, a strip plate slidably mounted on the inner wall of the movable groove, and a transmission rack fixedly connected to the side wall of the strip plate;

A gear is fixedly provided at the end of the rotating rod, and the gear meshes with the transmission rack.

[0007] Preferably, an anti-ultraviolet layer is fixedly connected to the outer wall of the PVC blade, and a heat-reflective layer is fixedly connected to the side of the anti-ultraviolet layer away from the PVC blade.

[0008] Preferably, a transmission hole is provided on the outer wall of one of the mounting brackets at the lower end of the main body. Fixing plates are fixedly connected to the outer walls of the mounting brackets on both sides of the transmission hole. A rotating shaft is rotatably connected to the fixing plate.

[0010] Preferably, an adjusting block is fixedly connected to the end of the rotating shaft away from the second gear.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. During use, the louver of this utility model, under the action of the anti-ultraviolet layer, can absorb or reflect ultraviolet rays, and form a light shielding layer by physically blocking and reflecting ultraviolet rays, thereby reducing the direct contact of ultraviolet rays with the substrate and thus improving the service life of the louver.

The strip plate 106 is slidably provided on the inner wall of the movable groove 102. The transmission rack 107 is fixedly connected to the side wall of the strip plate 106.

[0023] Multiple sets of PVC blades 104 are rotatably arranged between the two mounting brackets at the lower end of the main body 101. The two ends of each set of PVC blades 104 are rotatably connected to the mounting bracket through a rotating rod 103, and the rotating rod 103 extends into the interior of the movable groove 102. A gear 105 is fixedly provided at the end of the rotating rod 103, and the gear 105 meshes with the transmission rack 107.

[0025] During use, the UV-resistant layer 108 absorbs or reflects ultraviolet rays, forming a light-shielding layer by physically blocking and reflecting ultraviolet rays, thus reducing direct contact between ultraviolet rays and the substrate and improving the service life of the blinds. The heat-reflective layer 109 reflects solar heat and reduces the temperature of the profile, solving the problems of high energy consumption and easy deformation of traditional blinds in high-temperature environments. The UV-resistant layer 108 prevents material degradation due to sunlight, while the heat-reflective layer 109 reduces heat transfer, achieving dual energy saving through sun protection and heat insulation. This makes the blinds suitable for areas with stringent energy-saving building standards.

[0026] A transmission hole is provided on the outer wall of one of the mounting brackets at the lower end of the main body 101. Fixing plates 111 are fixedly connected to the outer walls of the mounting brackets on both sides of the transmission hole. A rotating shaft 112 is rotatably connected to the fixing plate 111.

[0027] A toothed plate 110 is provided on the inner side of the transmission hole. The toothed plate 110 is fixedly disposed on the side of the strip plate 106 away from the transmission rack 107. The toothed plate 110 meshes with the gear 113.

[0028] An adjusting block 114 is fixedly connected to the end of the rotating shaft 112 away from the gear 113.

[0029] When the angle of the PVC blades 104 in the blinds needs to be adjusted, the adjusting block 114 is rotated, which drives the rotating shaft 112 to rotate. The rotating shaft 112 drives the gear 113 to rotate. The gear 113 meshes with the toothed plate 110. During the rotation of the gear 113, the toothed plate 110 moves up and down. During the movement of the toothed plate 110, the strip plate 106 and the transmission rack 107 move synchronously. During the movement of the transmission rack 107, the gear 105 rotates. After the gear 105 rotates, it drives the rotating rod 103 and the PVC blades 104 to rotate, thereby completing the angle adjustment of the PVC blades 104. By controlling the angle change of the PVC blades 104, the indoor light intensity can be precisely controlled, which can adapt to the light requirements at different times and improve the flexibility of the blinds.

[0030] The working principle of the PVC co-extruded louver profile provided by this utility model is as follows: During use, under the action of the anti-ultraviolet layer 108, the anti-ultraviolet layer 108 can absorb or reflect ultraviolet rays, and the anti-ultraviolet layer 108 forms a light shielding layer by physically blocking and reflecting ultraviolet rays, reducing the direct contact of ultraviolet rays with the substrate, thereby improving the service life of the louver. Under the action of the heat reflective layer 109, the heat reflective layer 109 can reflect solar heat and reduce the temperature of the profile, solving the problems of high energy consumption and easy deformation of traditional louvers in high-temperature environments. The anti-ultraviolet layer 108 can prevent the material from degrading due to light, while the heat reflective layer 109 can reduce heat transfer, achieving dual energy saving of sun protection and heat insulation, making the louver suitable for areas with strict energy-saving building standards.

[0031] When the angle of the PVC blades 104 in the blinds needs to be adjusted, the adjusting block 114 is rotated, which drives the rotating shaft 112 to rotate. The rotating shaft 112 drives the gear 113 to rotate. The gear 113 meshes with the toothed plate 110. During the rotation of the gear 113, the toothed plate 110 moves up and down. During the movement of the toothed plate 110, the strip plate 106 and the transmission rack 107 move synchronously. During the movement of the transmission rack 107, the gear 105 rotates. After the gear 105 rotates, it drives the rotating rod 103 and the PVC blades 104 to rotate, thereby completing the angle adjustment of the PVC blades 104. By controlling the angle change of the PVC blades 104, the indoor light intensity can be precisely controlled, which can adapt to the light requirements at different times and improve the flexibility of the blinds.
