They are durable, easy to clean, non-aging, non-fading, sun-shading, heat-insulating, breathable and fire-resistant. They are suitable for high-end office buildings, living rooms, hotels, villas and other places.
[0003] A Chinese patent with announcement number CN2380675Y discloses a tension type Venetian blind, comprising an upper beam and a lower beam, with blades arranged in sequence in upper and lower order connected by ladder ropes, a steering device is provided in the upper beam, and an external rotating rod is used to rotate the device so that the tension of the ladder rope on the blades can adjust the shielding angle of the blades.
[0004] The above-mentioned rotating rod is rotated to adjust the shielding angle of the blades for all the blades, so the shielding angle of the blades in some areas cannot be adjusted separately, which has obvious shortcomings. Summary of the invention
[0005] In order to improve the problem that the shielding angles of all blades of a venetian blind can only be adjusted as a whole, the present application provides a venetian blind with an angle shielding control device.
[0006] The present application provides a venetian blind with an angle control device using the following technical solution:
[0007] A venetian blind with an angle control device comprises an upper beam, a lower beam, a plurality of blades arranged between the upper beam and the lower beam, and an elastic ladder rope connected to both sides of the length direction of each blade. Two parallel side beams are arranged between the upper beam and the lower beam, and the blades are located between the two side beams. A bracket and a driving member for driving the bracket to reciprocate and rise and fall are vertically slidable in the side beam, and a clamping member for clamping a single blade is arranged on the bracket.
[0008] By adopting the above technical solution, after the driving member drives the bracket to move to the appropriate position, the clamping member clamps the blades corresponding to the height. When adjusting the shielding angle, only the angles of other blades above the clamped blades change, while the blades below the clamped blades remain stationary, thereby achieving the purpose of adjusting the shielding angle of some blades and improving the versatility of the blinds.
[0009] Optionally, the driving member includes a motor electrically connected to a control system, the output shaft of the motor is coaxially provided with a lifting screw rod parallel to the side beam, and the bracket is threadedly connected to the lifting screw rod.
[0010] By adopting the above technical solution, the control system starts the motor, and the output shaft of the motor drives the lifting screw to rotate. Under the action of the thread matching, the screw is forced to move in the side beam.
[0011] Optionally, the clamping member includes a motor arranged on a bracket and electrically connected to a control system, the output shaft of the motor is coaxially provided with a bidirectional screw rod parallel to the lifting screw rod, the two threaded sections of the bidirectional screw rod are respectively threadedly connected to mounting plates, clamping blocks are respectively slidably provided on opposite sides of the two mounting plates, a top support block is provided at the midpoint of the length of the bidirectional screw rod, a guiding inclined surface is provided on the clamping block, the guiding inclined surface is inclined toward the blade along the direction from the two ends of the bidirectional screw rod to the top support block, and a tension spring is provided between the side of the clamping block facing away from the blade and the mounting plate.
[0012] By adopting the above technical solution, the control system starts the motor, and the output shaft of the motor drives the bidirectional screw to rotate. Under the action of the threaded cooperation, the two mounting plates drive the two clamping blocks to move away from each other or closer to each other. When the two clamping blocks approach each other, the guiding inclined surfaces of the clamping blocks contact the top support blocks and move relatively. The clamping blocks gradually approach the end of the blade, and finally the two clamping blocks cooperate to clamp the end of the blade, thereby limiting the blade and the blade below it.
[0013] Optionally, a slide groove parallel to the blade is provided on the bracket, and a protrusion sliding in the slide groove is provided on the clamping block, and the cross-sections of the slide groove and the protrusion are both C-shaped.
[0014] By adopting the above technical solution, the sliding groove and the protrusion play a guiding role in the relative sliding of the clamping block.
[0015] Optionally, a plurality of light bulbs are arranged vertically on the side beam, with one light bulb corresponding to one blade, a battery is placed on the upper beam, the negative poles of the plurality of light bulbs are connected to the negative pole of the battery through a first wire, a conductive connector is provided on the bracket, a second wire is connected between the conductive connector and the positive pole of the battery, and when the bracket drives the conductive connector to move, the conductive connector is connected to the positive pole of each light bulb in turn.
[0016] By adopting the above technical solution, during the movement of the bracket, the conductive connector will be connected to the positive pole of the bulb in turn, so that the battery, the first wire, the conductive connector, the corresponding bulb and the second wire will form a complete closed circuit, and the bulb will light up, so that the user can observe whether the bulb is lit, thereby improving the accuracy of the clamping member in clamping the blade.
[0017] Optionally, the conductive connector is slidably inserted into the bracket, an elastic sheet pressed against an outer side wall of the bracket is provided on the conductive connector, and a pull line is tied between the conductive connector and the clamping block.
[0018] By adopting the above technical solution, when the two clamping blocks cooperate to clamp the end of the blade, the pull wire pulls the conductive connector to move, so that the elastic sheet is deformed by force. At this time, the closed circuit is disconnected and the light bulb is extinguished, thereby saving battery power and extending the battery life.
[0019] Optionally, the elastic sheet is threadedly connected to the conductive joint.
[0020] By adopting the above technical solution, the conductive connector generates sliding friction with the inner wall of the side beam for a long time and is gradually worn out, so the user can remove the elastic sheet and replace the conductive connector.
[0021] Optionally, the side beam is coated with polytetrafluoroethylene.
[0022] By adopting the above technical solution, polytetrafluoroethylene can improve the smoothness of the inside of the side beam, thereby improving the smoothness of the movement of the bracket in the side beam.
[0023] In summary, the present application includes at least one of the following beneficial technical effects:
[0024] 1. After the driving member drives the bracket to move to a suitable position, the clamping member clamps the blades corresponding to the height.

The clamping blocks gradually approach the end of the blade, and finally the two clamping blocks cooperate to clamp the end of the blade, thereby limiting the blade and the blade below it.
[0026] 3. During the movement of the bracket, the conductive connector will be connected to the positive pole of the bulb in turn, so that the battery, the first wire, the conductive connector, the corresponding bulb and the second wire will form a complete closed circuit, and the bulb will light up. The user can observe whether the bulb is lit, so as to achieve accurate clamping of the blade;
[0027] 4. When the two clamping blocks cooperate to clamp the ends of the blades, the pull wire pulls the conductive connector to move, so that the elastic sheet is deformed by force. At this time, the closed circuit is disconnected and the light bulb goes out, thereby saving battery power and extending the battery life. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0032] The following is combined with Figure 1-3 This application is described in further detail.
[0033] The embodiment of the present application discloses a venetian blind with an angle shielding control device.
[0034] Reference Figure 1 The venetian blind with an angle control device includes an upper beam 1, a lower beam 2 and a plurality of blades 3 arranged between the upper beam 1 and the lower beam 2. Both sides of each blade 3 in the length direction are connected with elastic ladder ropes 4. A pulling device for pulling the elastic ladder ropes 4 on both sides of the blade 3 is also provided in the upper beam 1, so as to adjust the angle of the blade 3. The pulling device directly adopts the existing technology.
[0035] Reference Figure 1 and Figure 2 Two parallel side beams 5 with hollow interiors are bolted between the upper beam 1 and the lower beam 2 . The side beams 5 are perpendicular to the upper beam 1 and the lower beam 2 , and the blade 3 is located between the two side beams 5 .
[0036] A bracket 6 is vertically slidable in the side beam 5. The bracket 6 is concave in shape and the open side of the bracket 6 faces the opposite side of the two side beams 5. A driving member for driving the bracket 6 to reciprocate and lift, and a clamping member for clamping a blade 3 individually are also arranged in the side beam 5.
[0037] Reference Figure 2 The driving part includes a motor 7 bolted in the side beam 5 and electrically connected to the control system. The motor 7 adopts the forward and reverse motor 7 in the prior art. The output shaft of the motor 7 is coaxially provided with a lifting screw 8 parallel to the side beam 5, and the bracket 6 is threadedly connected to the lifting screw 8.
[0038] The control system starts the motor 7 , and the output shaft of the motor 7 drives the lifting screw 8 to rotate. Under the action of the threaded fit, the bracket 6 rises and falls in the side beam 5 , so that the clamping piece on the bracket 6 clamps the appropriate blade 3 .
[0039] Reference Figure 1 and Figure 2 The side beam 5 is coated with polytetrafluoroethylene, which can improve the smoothness of the inner surface of the side beam 5, so that the bracket 6 can move up and down more smoothly in the side beam 5.
[0040] Reference Figure 2 and Figure 3 The clamping member includes a motor 9 bolted to the bracket 6 and electrically connected to the control system. The output shaft of the motor 9 is coaxially provided with a bidirectional screw rod 10 parallel to the lifting screw rod 8. The two thread sections of the bidirectional screw rod 10 are both threadedly connected to the mounting plates 11. The opposite sides of the two mounting plates 11 are respectively slidably provided with clamping blocks 12.
[0041] A support block 13 is fixedly provided at the midpoint of the length of the bidirectional screw rod 10, and a guide slope 14 is provided on the clamping block 12. The guide slope 14 is inclined toward the blade 3 along the direction from the two ends of the bidirectional screw rod 10 to the support block 13, and a tension spring 15 is hung between the side of the clamping block 12 facing away from the blade 3 and the mounting plate 11.
[0042] Reference Figure 2 and Figure 3 After the bracket 6 moves to a suitable position, the control system starts the motor 9, and the output shaft of the motor 9 drives the bidirectional screw 10 to rotate. Under the action of the threaded fit, the two mounting plates 11 move closer to each other or away from each other.
[0043] When the two mounting plates 11 approach each other, the guiding slope 14 of the clamping block 12 will come into contact with the supporting block 13. Then, during the continuous movement, the two clamping blocks 12 will move toward the direction of the blade 3 and finally cooperate to clamp the end of the blade 3, and the tension spring 15 will also be stretched in the process.
[0044] When the end of the blade 3 is clamped, the wire pulling device pulls the elastic ladder wire, and at this time, all blades 3 above the blade 3 are tilted by force, so that the shielding angle can be adjusted. The blades 3 below the blade 3 all remain still.
[0045] Through the above-mentioned method, when the user adjusts the shielding angle, the shielding angle of some blades 3 can be adjusted separately, instead of adjusting the shielding angle of all blades 3, thereby improving the versatility of the venetian blind.
[0046] Reference Figure 2 and Figure 3The bracket 6 is provided with a slide groove 16 parallel to the blade 3, and the clamping block 12 is integrally formed with a protrusion 17 that slides in the slide groove 16, and the cross-sections of the slide groove 16 and the protrusion 17 are both C-shaped. The protrusion 17 cooperates with the slide groove 16 to guide the movement of the clamping block 12 and enhance its movement stability.
[0047] Reference Figure 2 and Figure 3 A plurality of light bulbs 18 are arranged vertically on the side beam 5, and one light bulb 18 corresponds to one blade 3. A battery 19 is placed in the upper beam 1, and the negative electrodes of the plurality of light bulbs 18 are connected to the negative electrode of the battery 19 through a first wire 20.
[0048] A conductive connector 21 parallel to the blade 3 is slidably provided on the bracket 6, and a second wire 22 is connected between the conductive connector 21 and the positive electrode of the battery 19. When the bracket 6 drives the conductive connector to move, the conductive structure is connected to the positive electrode of each bulb 18 in turn.
[0049] Reference Figure 2 and Figure 3 In the process of the bracket 6 driving the conductive connector 21 to move, the conductive connector 21 is connected to the motor 7 passing through each bulb 18 in turn. In this process, the battery 19, the first wire 20, the conductive connector 21, the bulb 18 and the second wire 22 will form a complete closed circuit, and the bulb 18 will light up, so that the user can observe whether the bulb 18 is lit, so that the clamp can accurately clamp the blade 3.
[0050] Reference Figure 2 and Figure 3 The conductive connector 21 is threadedly connected with an elastic sheet 23 pressed against the outer wall of the bracket 6, and a pull wire 24 is tied between the conductive connector 21 and the clamping block 12. When the clamping block 12 clamps the blade 3, the pull wire 24 pulls the conductive connector 21 to move, so that the conductive connector 21 is out of contact with the positive pole of the light bulb 18, the circuit is disconnected, and the light bulb 18 is extinguished, thereby saving the power of the battery 19 and extending the service life of the battery 19.
[0051] The implementation principle of the venetian blind with an angle control device in the embodiment of the present application is as follows: the control system starts the motor 7, and the output shaft of the motor 7 drives the lifting screw 8 to rotate. Under the action of the threaded fit, the bracket 6 is lifted and lowered in the side beam 5. In the process of the bracket 6 driving the conductive connector 21 to move, the conductive connector 21 is sequentially connected to the motor 7 passing through each light bulb 18. In this process, the battery 19, the first wire 20, the conductive connector 21, the light bulb 18 and the second wire 22 will form a complete closed circuit, and the light bulb 18 will light up. The height of the bracket 6 is suspended at the position where the light bulb 18 lights up.
[0052] The control system starts the motor 9, and the output shaft of the motor 9 drives the bidirectional screw 10 to rotate. Under the action of the threaded fit, the two mounting plates 11 approach each other or move away from each other. When the two mounting plates 11 approach each other, the guide slope 14 of the clamping block 12 will contact the top support block 13. Then, in the process of continuous movement, the two clamping blocks 12 move toward the direction of the blade 3 and finally cooperate to clamp the end of the blade 3, and the tension spring 15 is also stretched in the process. In this process, the pull wire 24 pulls the conductive connector 21 to move, so that the conductive connector 21 is out of contact with the positive pole of the light bulb 18, the circuit is disconnected, and the light bulb 18 is extinguished, thereby saving the power of the battery 19.
[0053] When the end of the blade 3 is clamped, the wire pulling device pulls the elastic ladder wire. At this time, all the blades 3 located above the blade 3 are tilted by the force, so that the shielding angle can be adjusted, while the blades 3 located below the blade 3 all remain still, so that only the shielding angle of some blades 3 can be adjusted.
[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
