Description

Technical Field

[0001] This application relates to the field of outdoor sunshade equipment, and in particular to a pivot blade and an electric louver. Background Technology

[0002] Motorized venetian blinds are a common light-blocking structure. By adjusting the angle of the slat units in the venetian blinds, the amount of light entering the blinds can be controlled.

[0003] The motorized louver includes a mounting frame, louver assemblies mounted inside the mounting frame, and a drive mechanism for rotating the louver assemblies. The louver assembly includes multiple parallel-arranged blade units and a synchronizing link connecting the blade units. Each blade unit includes a blade body and blade end caps mounted at both ends of the blade body. The blade end caps are locked to the blade body with screws, and each end cap has a rotating shaft in its center for engaging with the mounting frame.

[0004] Regarding the aforementioned technologies, when the electric louvers are applied outdoors, the blade units are prone to deformation of the rotating shaft when subjected to external impacts, which may cause the blade units to jam. Utility Model Content

[0005] In order to reduce the probability of deformation of the rotating shaft when the blade unit is subjected to external impact, this application provides a rotating shaft blade and an electric louver.

[0006] In a first aspect, this application provides a rotating blade, which adopts the following technical solution: A rotating blade includes a blade body and a rotating shaft end cap mounted on the end of the blade body; the end of the blade body has a limiting groove; the rotating shaft end cap includes a mounting cover plate mounted on the end of the blade body, a T-shaped bolt arranged in the limiting hole and passing through the mounting cover plate, a round nut mounted on the T-shaped bolt and abutting against the mounting cover plate, and a rotating shaft sleeve sleeved on the outside of the round nut.

[0007] By adopting the above technical solution, the combination of the blade body and the shaft end cover is easy to install. The limiting groove allows the T-bolt to be locked to the blade body. The T-bolt, together with the round nut and the mounting cover plate, realizes the stable installation of the shaft end cover and the blade body. The rotating shaft sleeve is fitted on the outside of the round nut to protect and assist rotation, so that the blade can withstand external impacts and reduce the probability of deformation of the rotating shaft.

[0008] Optionally, the T-bolt includes a limiting rod arranged at the limiting groove and a threaded rod connected to the limiting rod for the arrangement of the round nut; the mounting cover plate has a through hole for the threaded rod to pass through.

[0009] By adopting the above technical solution, the limiting rod can restrict the position of the T-bolt, and the mounting cover plate is provided with a through hole for the threaded rod to pass through, so that the round nut can fix the T-bolt on the blade body and abut against the mounting cover plate, so that the T-bolt can be firmly installed at the end of the blade body.

[0010] Optionally, the end of the rotating bushing facing the mounting cover plate is provided with a limiting ring for abutting against the inner side of the mounting frame.

[0011] By adopting the above technical solution, the rotating bushing is fitted onto the outside of the round nut, and the end of the rotating bushing has a limiting ring that can abut against the inner side of the mounting frame. This limits the position of the rotating blade within the mounting frame, reducing the probability of axial movement when the rotating blade rotates. This ensures the stability of the rotating blade installation and the reliability of its use.

[0012] Optionally, the blade body is provided with locking grooves on both sides of the limiting groove; both ends of the mounting cover are provided with locking screws that cooperate with the locking grooves, and the mounting cover has locking countersunk holes for arranging the locking screws.

[0013] By adopting the above technical solution, a locking method between the mounting cover and the blade body is disclosed. The locking screw and the locking groove cooperate to ensure that the mounting cover can be stably installed at the end of the blade body, and the locking countersunk hole can accommodate the locking screw, preventing it from protruding and affecting other components.

[0014] Secondly, this application provides an electric louver, which adopts the following technical solution: An electric louver includes a mounting frame, a louver assembly mounted inside the mounting frame, and a drive mechanism for driving the louver assembly to rotate; the louver assembly includes a pivot blade as described in any one of the above, an adapter mounted at the end of the pivot blade, and a transmission link connecting the adapter.

[0015] By adopting the above technical solution, the mounting frame provides overall support and a foundation for the motorized louvers; the rotating blades, with the cooperation of T-bolts, round nuts, and rotating bushings, achieve the connection and rotation between the blade body and the mounting frame. The adapter and transmission linkage connect the rotating blades, facilitating the drive mechanism to rotate the louver assembly; the drive mechanism can drive the louver assembly to rotate, realizing the opening and closing function of the motorized louvers.

[0016] Optionally, the adapter includes a first adapter portion sleeved on the end of the T-bolt and a second adapter portion for connecting with the transmission link; the T-bolt is also provided with a lock nut to prevent the first adapter portion from coming out.

[0017] By adopting the above technical solution, the rotating shaft blades and the adapter are connected by sleeve connection between the end of the T-bolt and the first adapter, and the second adapter is connected to the transmission rod to realize transmission. The anti-loosening nut can lock the rotating shaft blades on the mounting frame and lock the first adapter to the end of the T-bolt, ensuring the stability of the connection of each component of the electric louver and the reliability of the transmission.

[0018] Optionally, the second adapter is connected to the transmission link by rivets.

[0019] By adopting the above technical solution, a locking method between the second adapter and the transmission link is disclosed, so that the second adapter and the transmission link can be firmly locked together.

[0020] Optionally, the drive mechanism includes an electric push rod with its tail end hinged to the mounting frame; both ends of the rotating shaft blade are provided with transmission links, the two transmission links being a first transmission link closer to the electric push rod and a second transmission link arranged away from the electric push rod; the first transmission link has a drive protrusion for hinged with the piston rod of the electric push rod.

[0021] By adopting the above technical solution, the tail end of the electric push rod is hinged to the mounting frame, and the first transmission link is hinged to the piston rod of the electric push rod through the drive protrusion. This allows the electric push rod to extend or retract, driving the first transmission link to move. This, in turn, causes the rotating shaft blades to flip via the adapter, thus controlling the opening and closing of the louvers. Transmission links are provided at both ends of the rotating shaft blades, making the opening and closing of the louvers more stable.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. A rotating shaft blade, wherein a T-bolt, a round nut, and a mounting cover plate are used to securely install the rotating shaft end cover and the blade body, and a rotating bushing protects the rotating shaft and assists in rotation; 2. By setting a limiting ring at the end of the rotating bushing, the position of the rotating blade within the mounting frame can be limited, reducing the probability of axial movement when the rotating blade rotates; 3. An electric louver, wherein the louver assembly can be rotated under the drive of a drive mechanism to realize the opening and closing function of the electric louver; 4. The rotating shaft blades are connected by an adapter and a transmission link, which facilitates the drive mechanism to drive the transmission link to rotate the rotating shaft blades, thereby realizing the rotation of the louver assembly.

[0036] Reference Figure 3 and Figure 4 The outer frame 31 has a first through hole that penetrates the side and is used for mounting the rotating shaft blades. The inner frame 32 has a second through hole that penetrates the side and corresponds to the first through hole. When the rotating shaft blades are mounted on the inner side of the mounting frame 3, the T-bolts 22 of the rotating shaft blades pass through the first and second through holes respectively. The rotating bushing 24 passes through the first and second through holes, and the outer side wall of the rotating bushing 24 abuts against the outer frame 31 and the inner frame 32. The first adapter part 411 is fitted onto the end of the T-bolt 22. To prevent the first rotating shaft from coming off the end of the T-bolt 22 during transmission, the T-bolt 22 is provided with a lock nut 6 to prevent the first adapter part 411 from coming off. The second adapter part 412 is connected to the transmission connecting rod 42, wherein the second adapter part 412 and the transmission connecting rod 42 are connected by rivets. In this embodiment, the distance between the outer frame 31 and the inner frame 32 is not greater than the axial length of the rotating bushing 24.
