Description

Technical Field

[0001] This utility model relates to the technical field of louvers, and in particular to a blade transmission structure and a louver. Background Technology

[0002] Currently, to achieve synchronous adjustment of multiple slats in a venetian blind, a slat transmission structure needs to be incorporated into the blind. For example, a patent with publication number CN218598119U discloses a transmission structure for a hidden slat pull rod in a venetian blind. This structure uses multiple gears meshing between a left and right rack, both of which are long racks, and connects the rotating shafts of multiple slats to these gears to achieve synchronous adjustment of the slats. However, since both sides of the gears are connected via long racks, the long racks require high precision to meet the requirements. During use, insufficient rack precision can easily cause the slats to fail to rotate, affecting the service life. Furthermore, the left and right racks, both of which are long racks, cannot be well adapted to venetian blinds of different sizes. When the rack size is incompatible, a new mold must be made, resulting in poor versatility. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art. The primary objective is to provide a blade transmission structure that reduces the precision requirements of the rack and pinion, has a long service life, and is versatile.

[0004] The second objective of this invention is to provide a louver that reduces the precision requirements of the rack and pinion, has a long service life, and is highly versatile.

[0005] The technical solution adopted by this utility model is as follows: the blade transmission structure includes a mounting plate and a connecting plate disposed in the vertical beam of the window. The mounting plate is provided with a plurality of transmission units in sequence along the length direction. The transmission unit includes a fixed seat and a buckle. The fixed seat is fixedly connected to the mounting plate. A sliding seat is slidably connected to the fixed seat. A rack is disposed on the sliding seat. A first mounting hole is opened on the mounting plate. One end of the buckle is connected to the blade. The other end of the buckle extends into the first mounting hole and is connected to the transmission gear. The rack is located on one side of the transmission gear and is connected to the transmission gear in a transmission connection. The connecting plate is fixedly connected to the plurality of sliding seats.

[0006] Furthermore, the fixing base has a plug with a second mounting hole, the plug extending into the first mounting hole, one end of the transmission gear extending into the second mounting hole, and the buckle extending into the first mounting hole and the second mounting hole in sequence.

[0007] Furthermore, the fixed base is provided with a first chamber and a second chamber, and a partition block is provided between the first chamber and the second chamber. The sliding seat is slidably connected in the first chamber. One side of the second chamber is connected to the first chamber, and the other side is connected to the second mounting hole. The transmission gear and the rack are both located in the second chamber.

[0008] Furthermore, the mounting plate is provided with a slot, and the fixing base is provided with a locking block that cooperates with the slot.

[0009] Furthermore, the sliding seat is provided with an elongated hole, and the other end of the transmission gear is connected to the elongated hole.

[0010] Furthermore, a fixing groove is provided on the side of the sliding seat away from the mounting plate. A limit block and a fixing protrusion are provided in the fixing groove. The connecting plate is fitted in the fixing groove. The limit block abuts against the connecting plate. A fixing hole is provided on the connecting plate. The fixing protrusion is inserted into the fixing hole.

[0011] In addition, this utility model also provides a louver, which includes the aforementioned blade transmission structure.

[0012] The beneficial effects of this utility model are:

[0013] In contrast to the shortcomings of existing technologies, this invention reduces the length of the racks by using multiple racks corresponding to multiple transmission gears and by connecting the racks only to one side of the transmission gears. This makes it easier to control the machining accuracy of the racks and lowers the accuracy requirements. This not only ensures the smoothness of the blade rotation but also avoids the situation where the blades cannot rotate due to substandard rack accuracy, thus guaranteeing service life. Furthermore, by using multiple transmission units, the appropriate number of transmission units can be adapted according to the size of the louvers, providing good flexibility and versatility. As a result, the blade transmission structure has the advantages of reduced rack accuracy requirements, long service life, and good versatility. Attached Figure Description

[0027] like Figures 1 to 6 As shown, in this embodiment, the blade transmission structure includes a mounting plate 2 and a connecting plate 3 disposed in the window frame vertical beam 1. Multiple transmission units 5 are sequentially arranged along the length of the mounting plate 2. Each transmission unit 5 includes a fixing seat 6 and a buckle 7. The fixing seat 6 is fixedly connected to the mounting plate 2, and a sliding seat 8 is slidably connected to the fixing seat 6. A rack 9 is disposed on the sliding seat 8. A first mounting hole 10 is opened on the mounting plate 2. One end of the buckle 7 is connected to the blade 11, and the other end of the buckle 7 extends into the first mounting hole 10 and is connected to a transmission gear 12. The rack 9 is located on one side of the transmission gear 12 and is drively connected to the transmission gear 12. The connecting plate 3 is fixedly connected to the multiple sliding seats 8. The connection plate 3 and the multiple sliding seats 8 are fixedly connected to enable the multiple transmission units 5 to move together. The connecting plate 3 is made of aluminum; the mounting plate 2 and the transmission units 5 are made of plastic, specifically POM plastic.

[0028] When adjustment is needed, the buckle 7 is rotated by one blade 11, which drives the transmission gear 12 to rotate. Since the rack 9 is located on one side of the transmission gear 12 and meshes with the transmission gear 12, the rack 9 and the sliding seat 8 can move upward or downward along the length of the window vertical beam 1. Since the connecting plate 3 is fixedly connected to multiple sliding seats 8, multiple sliding seats 8 can move simultaneously. At this time, multiple buckles 7 can rotate synchronously, thereby realizing the synchronous adjustment of multiple blades 11.

[0029] In contrast to the shortcomings of existing technologies, this invention reduces the length of the racks 9 by using multiple racks 9 corresponding to multiple transmission gears 12 and by connecting the racks 9 only to one side of the transmission gears 12. This makes it easier to control the machining accuracy of the racks 9 and lowers the accuracy requirements. This not only ensures the smoothness of the blade 11 rotation but also avoids the situation where the blade 11 cannot rotate due to substandard rack accuracy, thus ensuring service life. Moreover, by using multiple transmission units 5, the appropriate number of transmission units 5 can be adapted according to the size of the louver, providing good flexibility and versatility. As a result, the blade transmission structure has the advantages of reduced rack accuracy requirements, long service life, and good versatility.

[0030] In some embodiments, the fixing base 6 has a plug 13 with a second mounting hole 15. The plug 13 extends into the first mounting hole 10, and one end of the transmission gear 12 extends into the second mounting hole 15. The latch 7 extends into the first mounting hole 10 and the second mounting hole 15 in sequence. Specifically, after the latch 7 extends into the first mounting hole 10 and the second mounting hole 15 in sequence, it connects with the transmission gear 12 extending into the second mounting hole 15.

[0031] In some embodiments, the fixed base 6 is provided with a first chamber 16 and a second chamber 17, and a partition block 18 is provided between the first chamber 16 and the second chamber 17. The sliding base 8 is slidably connected in the first chamber 16. One side of the second chamber 17 is connected to the first chamber 16, and the other side is connected to the second mounting hole 15. The transmission gear 12 and the rack 9 are both located in the second chamber 17.

[0032] In some embodiments, the mounting plate 2 is provided with a slot 19, and the fixing base 6 is provided with a locking block 20 that cooperates with the slot 19. Specifically, the fixing base 6 is inserted into the first mounting hole 10 through the insert block 13, and cooperates with the slot 19 through the locking block 20, so that the fixing base 6 can be firmly connected to the mounting plate 2.

[0033] In some embodiments, the sliding seat 8 is provided with an elongated hole 21, and the other end of the transmission gear 12 is connected to the elongated hole 21. A fixing groove 22 is provided on the side of the sliding seat 8 away from the mounting plate 2. A limit stop 23 and a fixing protrusion 25 are provided in the fixing groove 22. The connecting plate 3 is fitted into the fixing groove 22, and the limit stop 23 abuts against the connecting plate 3. The connecting plate 3 is provided with a fixing hole 26, and the fixing protrusion 25 is inserted into the fixing hole 26. Specifically, the setting of the limit stop 23 and the fixing protrusion 25 ensures that the connecting plate 3 can be stably connected to the sliding seat 8.

[0034] In addition, such as Figure 6 As shown, this utility model also provides a venetian blind, which includes the aforementioned blade drive structure. Specifically, the specific structure of the blade drive structure is as described in the above embodiments. Since the blade drive structure adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.
