[0024] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0025] Example 1

[0026] like Figure 1-Figure 4 As shown, a splicable louver profile includes a louver profile body 1 and an extension profile 2.

[0027] The louver profile body 1 can be used as a blade structure of a louver. The extension profile 2 can be used as an extension device of the louver profile body 1. The louver profile body 1 and the extension profile 2 are made of aluminum, and the surfaces of the louver profile body 1 and the extension profile 2 are powder-coated to protect the louver from the influence of the weather.

[0028] The louver profile body 1 and the extended profile 2 have a certain curvature. The curvature of the louver profile body 1 is 0.84-0.88 rad, and the curvature of the extended profile 2 is 0.31-0.33 rad.

[0029] The surface of the louver profile body 1 is provided with a T-shaped protrusion 101, and the T-shaped protrusion 101 is integral with the louver profile body 1. The surface of the extended profile 2 is provided with a boss 201 corresponding to the T-shaped protrusion 101, and the boss 201 is integral with the extended profile 2. The T-shaped protrusion 101 is provided on the side of the concave surface of the upper edge of the louver profile body 1. The boss 201 is provided on the side of the concave surface of the upper edge of the extended profile 2. A groove is provided inside the boss 201, and the shape of the groove is consistent with that of the T-shaped protrusion 101.

[0030] The shutter profile body 1 can be connected to the boss 201 of the extension profile 2 via the T-shaped protrusion 101. The blade shape formed after the combination is S-shaped.

[0031] The louver profile body 1 is provided with a plurality of groups of mounting holes 102 penetrating the louver profile body 1, and each group of mounting holes 102 is arranged at intervals, and each group of mounting holes 102 has three, which are arranged below the T-shaped protrusion 101 of the louver profile body 1, at the middle end of the louver profile body 1, and at the lower end of the louver profile body 1. The mounting holes 102 can adjust the angle of the louver profile body 1 on the louver, so that the louver has the function of controlling the amount of sunlight entering the room and the amount of wind entering the room.

[0032] The blinds are composed of blades, a basic frame, and an adjustment device. The blind profile body 1 is the basic structure of the blinds blades, the basic frame provides support for the blades, and the adjustment device can adjust the angle of the blades. The adjustment device controls the adjustment range of the blades to be 0°-105°.

[0033] The basic frame is composed of four plates with grooves, and the material is aluminum or wood. The basic frame is installed on the inside of the window. An adjustment device is provided in the upper basic frame, and the adjustment device extends two lines from the upper basic frame to the lower basic frame, one of which is a support line that can control the spacing size of the louver profile body 1 and provide support for the louver profile body 1. The other is a control line, one end of which is connected to the louver profile body 1 to control the angle of the louver profile body 1, and the other end of the control line is connected to the adjustment device, and is not in the plane of the basic frame. The function of increasing or decreasing the angle between the blades is achieved by using two lines or a rotating rod.

[0034] A plurality of louver profile bodies 1 are arranged at intervals between the support lines in the basic frame. The number of louver profile bodies 1 is determined by the distance between the support lines and the distance between the basic frames at the upper and lower ends. The support lines pass through the mounting holes 102 at the middle end of the louver profile bodies 1. A locking device is arranged below the mounting hole at the middle end of the bottom louver profile body 1 and connected to the end of the support line. This ensures that the intervals between the louver profile bodies 1 are fixed and the bottom louver profile body 1 will not fall off.

[0035] The other end of the support wire is fixed to the inner side of the adjustment device. The support wire can be retracted into the adjustment device. When the blinds are in use, sometimes the interval between the blades needs to be reduced. This allows certain objects to pass through the blinds. At this time, the length of the support wire in the base frame can be changed by the adjustment device. This reduces the interval between the blind profile bodies 1. Certain objects can pass through the blinds. When it is not necessary to pass through the blinds, the support wire can keep the distance between the blinds unchanged.

[0036] The control line consists of three lines, two of which have one end set in the adjustment device and the other end set below the T-shaped protrusion 101 of the louver profile body 1 and at the mounting holes at the lower end of the louver profile body 1. One end of the third control line is connected to the adjustment device and the other end is a connecting rod or connected to the knob.

[0037] By rotating the connecting rod or knob, the angle between the blades can be changed. When the connecting rod is used for control, a worm is arranged inside the adjustment device. When the connecting rod is rotated, the worm can transfer the rotational power to two control wires connected to the blades. The control wires control the opening and closing angles of the blades on the blinds.

[0038] When a knob connection is used, a receiver is provided inside the adjusting device. The knob can generate a light signal. The adjusting device receives the light signal and controls the extension or shortening of two control lines connected to the blades according to the type of the light signal.

[0039] After the blinds are installed, the extension profile 2 can be installed according to the usage conditions.

[0040] When the light intensity is too high, the rain is heavy, the wind volume is high, etc., the influence of the weather on the interior can be reduced by installing the extension profile 2.

[0041] After the extension profile 2 is installed, the blade shape of the blind changes from an arc with a certain curvature to an S-shaped arc. The blades can be connected to each other after adjusting the angle. Wind cannot directly enter the room through the gaps between the blades. Light, rain, etc. are also not easy to enter the room due to the obstruction of the extension profile 2.

[0042] The connection between the other end of the extended profile 2 and the other set of louver profile body 1 can be provided with a rubber strip, a protrusion or other protective device. The lower end of the concave surface of the louver profile body 1 can also be provided with a rubber strip, a protrusion or other protective device. The waterproof rate and light blocking rate between the blades of the louver window can be improved.

[0043] Embodiment 2, the blinds are composed of blades and frames. The frames include 4 pieces, which are respectively installed on the upper, lower, left and right sides of the window. The frames on the left and right sides are provided with fixing plates of the blind profile body 1. There is no mounting hole 102 on the upper surface of the blind profile body 1. By fixing the blind profile body 1 on the fixing plate. The position and angle of the blind profile body 1 on the blinds can be fixed. And an angle adjustment plate is provided at the frame on any one of the left and right sides. The angle of the blinds can be adjusted. This installation method cannot conveniently change the spacing of the blind profile body 1 on the blinds.

[0044] After installing the extended profile 2, this installation method still has good water and wind blocking functions. Without the extended profile 2, this installation method has good light transmittance and ventilation effects.

[0045] When the extension profile 2 of the utility model is installed on the louver profile body 1, the joint part is completely hidden inside the assembled louver plate, and the joint part fits very tightly, effectively preventing dust from entering the room. Dust accumulates on the contact surface between the extension profile 2 and the louver profile body 1. When cleaning, just remove the extension profile 2 for cleaning. It is convenient for people to clean. After using it for a period of time, or after blocking a lot of rainwater, the surface of the louver needs to be cleaned. The extension profile 2 can be removed from the louver profile body 1, which is more convenient for cleaning. The louver profile body 1 can also be removed from the louver for easy cleaning.

[0046] The above shows and describes the basic principles, main features and advantages of the utility model.
