Description

Technical Field

[0001] The utility model belongs to the technical field of hollow blinds, and in particular relates to a hollow blind with a built-in sunshade structure. Background Art

[0002] Venetian blinds are windows with shutters installed. They are generally used for indoor and outdoor use, ventilation, and are very beautiful. They are usually arranged in a double-glazed window structure. The shutters are installed between the two layers of glass in the double-glazed window, and the opening or closing of the shutters is completed by control components.

[0003] Existing control components of Venetian blinds generally use ropes to connect and drive the blinds to tilt at a certain angle. Usually, a sleeve rod is set on one side of the blinds, and the rope is pulled by a moving sleeve rod or a telescopic sleeve rod to adjust the blinds, so that the blinds are flipped, thereby completing the opening or closing of the blinds. However, when the blinds are flipped and closed for shading, although the blinds themselves have a certain sunshade function, when the sunlight is strong, some sunlight will still pass through the gaps between the blinds, so that the room will feel brighter sunlight, which makes the blinds unable to completely block the sunlight.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1-4 A hollow shutter with a built-in sunshade structure is shown, comprising:

[0023] A window frame 1, wherein fixed plates 2 are provided on both sides of the window frame 1, and a plurality of blades 3 are rotatably connected between the two groups of fixed plates 2 via a rotating shaft 14. An adjustment groove 4 is provided in one end of the window frame 1 and located on one side of the fixed plate 2. A guide rod 5 is provided in the adjustment groove 4. A slide plate 6 for adjusting the rotation angle of the blade 3 is slidably sleeved on the surface of the guide rod 5. A sunshade assembly 7 for enhancing the shading effect of the hollow blind is provided in the window frame 1. The counterweight block 8 of the sunshade assembly 7 drives a sunshade cloth 9 to slide on the surface of the sliding rod 10 so that the sunshade cloth 9 covers the window frame 1.

[0024] The sunshade assembly 7 includes a storage box 11 and a motor 12. The storage box 11 is arranged on the top of the window frame 1. A winding drum 13 is rotatably connected inside the storage box 11. The sunshade cloth 9 is rolled up on the surface of the winding drum 13. The material of the sunshade cloth 9 is polyester. Polyester has excellent light-shielding effect and UV protection function, and its texture is relatively soft and easy to roll up.

[0025] The motor 12 is disposed in the storage box 11 and the output shaft of the motor 12 is connected to the winding drum 13 . When the motor 12 is working, it can drive the winding drum 13 to rotate to unwind or rewind the sunshade cloth 9 .

[0026] The sliding rod 10 is provided with two groups and is respectively arranged on both sides of the back of the window frame 1. The counterweight block 8 is slidably sleeved on the surface of the sliding rod 10. One end of the sunshade cloth 9 is movable through the storage box 11 and connected to the two groups of counterweight blocks 8. The piston rod of the cylinder 19 pushes the slide plate 6 to slide on the surface of the guide rod 5, and while the slide plate 6 moves, the transmission block 16 slides in the transmission hole 15 and drives the rotating rod 17 to rotate through the rotating shaft 14.

[0027] The surface of the slide plate 6 is provided with a plurality of transmission holes 15 , and a rotating rod 17 is slidably connected in the transmission hole 15 via a transmission block 16 , and the other end of the rotating rod 17 is fixedly sleeved on the surface of the rotating shaft 14 .

[0028] A mounting groove 18 is provided in the bottom of one side of the window frame 1, and a cylinder 19 is provided in the mounting groove 18. The piston rod of the cylinder 19 is connected to the slide plate 6. When the cylinder 19 is working, the slide plate 6 can be driven by the piston rod of the cylinder 19 to slide on the surface of the guide rod 5, thereby enhancing the stability of the movement of the slide plate 6.

[0029] The hollow blind with built-in sunshade structure can start the motor 12 to work when the sunshade effect is adjusted when the blades 3 are in the closed state. The output shaft of the motor 12 rotates forward to drive the winding drum 13 in the storage box 11 to rotate forward, so that the rotating winding drum 13 starts to unwind the sunshade cloth 9, and one end of the unwound sunshade cloth 9 slides on the surface of the slide rod 10 under the gravity of the counterweight block 8, so that the sunshade cloth 9 is driven by the sliding counterweight block 8 to move from the top of the window frame 1 to the bottom of the window frame 1, so as to cover the back of the window frame 1, so that the sunlight passing through the gap of the blind is effectively blocked by the sunshade cloth 9, thereby enhancing the sunshade effect of the blind and preventing the sunlight passing through the gap of the blind from shining into the room; because the sunshade cloth 9 can also reduce the situation of wind entering the window from the blades 3 at this time;

[0030] When the sunshade cloth 9 is rolled up, the output shaft of the control motor 12 is reversed, driving the winding drum 13 in the storage box 11 to rotate in the opposite direction, thereby rolling up the unrolled sunshade cloth 9, so that one end of the sunshade cloth 9 moves from the bottom of the window frame 1 to the top of the window frame 1 under the action of the counterweight block 8, thereby completing the rolling of the sunshade cloth 9.

[0031] When the closed shutter blades 3 are opened, the cylinder 19 can be started to work, and the piston rod of the cylinder 19 pushes the slide plate 6 to slide on the surface of the guide rod 5, and while the slide plate 6 moves, the transmission block 16 slides in the transmission hole 15 and drives the rotating rod 17 to rotate through the rotating shaft 14, and while driving the rotating shaft 14 to rotate, the blade 3 rotates clockwise with the rotating shaft 14 as the center point, thereby driving the blade 3 to flip and open the blade 3. When the blade 3 needs to be closed, the cylinder 19 is started to work, and the piston rod of the cylinder 19 retracts to drive the slide plate 6 to slide on the surface of the guide rod 5, and slides in the transmission hole 15 through the transmission block 16 to drive the rotating rod 17 to rotate through the rotating shaft 14, so that the blade 3 rotates counterclockwise with the rotating shaft 14 as the center point, thereby driving the blade 3 to flip and close the blade 3, making the opening and closing of the blade 3 more convenient and the adjustment more convenient.

[0032] The utility model can be manually adjusted by correspondingly connecting switch buttons to the motor 12 and the cylinder 19, such as a switch for controlling the forward and reverse rotation of the motor 12, and a switch for controlling the extension or retraction of the cylinder 19. Intelligent control can also be adopted, such as connecting to a Siemens PLC or a single-chip microcomputer STM32 for control. Since both are existing control technologies, they will not be described in detail here.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
