Detailed Description
As shown in fig. 1, the present embodiment is a single-opening type retractable electric curtain rail, which has a retractable curtain rail housing and a retractable single-opening traction mechanism installed in the curtain rail housing.
In this embodiment, the curtain rail housing is composed of a large housing 10 and a small housing 11, wherein one end of the small housing 11 is coaxially inserted into the large housing 10, and the relative positions of the large and small housings 10 and 11 are adjusted in the axial direction to realize the telescopic adjustment of the curtain rail housing, thereby changing the length of the curtain rail housing to adapt to the widths of different windows.
As shown in fig. 2, the single-open traction mechanism in this embodiment includes a motor transmission case 2 connected to a motor 1 and installed at the left end of the curtain rail housing, a tail end bearing bracket 3 installed at the right end of the curtain rail housing, and a telescopic screw rod axially arranged parallel to the curtain rail housing. One end of the telescopic screw rod is connected with the motor transmission case 2 and is connected with the output shaft of the motor 1 through the transmission of the motor transmission case 2, the other end of the telescopic screw rod is connected with the tail end bearing support 3, and the telescopic screw rod is provided with a hook slide block 6.
The telescopic screw rod in the embodiment is provided with a small screw rod 5 and a large screw rod 4 which is coaxially sleeved on the small screw rod 5 and is in threaded connection with the small screw rod 5, the left end of the large screw rod 4 is connected with a motor transmission case 2, the right end of the large screw rod 4 is coaxially sleeved on the small screw rod 5, and the right end of the small screw rod 5 is connected with a tail end bearing support 3.
In this embodiment, the inner wall of the hook slider 6 is divided into a left section and a right section, the left section is a threaded section 602 provided with an internal thread i, the right section is a smooth sleeve section 603 with an internal diameter larger than that of the threaded section 602, and the threaded section 602 is adapted to the large screw rod 4 (see fig. 4).
In this example, a clutch mechanism (see fig. 3) capable of being combined with the hook sliding block 6 is arranged on the small screw rod 5, the clutch mechanism is provided with a base 7 (see fig. 5), an internal thread II matched with the small screw rod 5 is formed on the inner wall of the base 7, and the outer diameter of the base 7 is matched with the inner diameter of the insertion section of the hook sliding block 6. A connecting sleeve 8 (see fig. 6) capable of being combined with the hook sliding block 6 is coaxially sleeved on the base 7, a spring is arranged at the end, far away from the hook sliding block 6, of the connecting sleeve 8, the spring is coaxially sleeved on the base 7, one end of the spring is connected with the connecting sleeve 8, and the other end of the spring is connected with the base 7 through a blocking piece 9.
In this embodiment, a positioning block 601 is formed at the end of the hook sliding block 6 facing the end of the connecting sleeve 8; the connecting sleeve 8 is provided with a positioning groove 801 matched with the positioning block 601 on the hook sliding block 6. The end of the connecting sleeve 8 facing the hook sliding block 6 is provided with a magnetic sheet capable of adsorbing the hook sliding block 6. The connecting sleeve 8 of the embodiment magnetically attracts the hook sliding block 6, and is matched with the positioning groove 801 through the positioning block 601 to prevent relative rotation.
In this embodiment, the outer wall of the base 7 is provided with a limiting block 701, and the connecting sleeve 8 is provided with a limiting groove arranged along the axial direction of the connecting sleeve 8 corresponding to the limiting block 701, so as to prevent the connecting sleeve 8 from rotating around the base 7. The limiting groove is not separately arranged in the embodiment, and the positioning groove 801 is matched with the limiting block 701 to prevent the connecting sleeve 8 from rotating around the base 7.
This embodiment is kept away from of base 7 and is had the external screw thread on the 6 end of couple slider, and separation blade 9 threaded connection realizes the regulation to the spring on the external screw thread of base 7 through adjusting separation blade 9 of threaded connection on the external screw thread of base 7.
The working principle of the embodiment is as follows: before the rail is installed, when the length of the electric curtain rail needs to be adjusted, pulling force or pressure is applied to the electric curtain rail along the axial direction of the electric curtain rail, and because the curtain rail shell in the electric curtain rail is formed by coaxially inserting large and small shells 10 and 11, the length of the electric curtain rail can be easily changed under the action of the pulling force or the pressure so as to meet the installation requirement; the telescopic screw rod stretches under the action of tension or pressure, and finally the length of the single-opening traction mechanism is changed to meet the installation requirement.
After the installation of the electric curtain rail is finished, the length of the electric curtain rail is fixed, and when the motor 1 drives the large screw rod 4 to rotate, the large screw rod 4 drives the small screw rod 5 to synchronously rotate.
When the big screw rod 4 rotates forwards, the hook slide block 6 on the big screw rod 4 moves from left to right, the clutch mechanism is positioned at the joint of the small screw rod 5 and the big screw rod 4, and the clutch mechanism does not receive external force at the moment, so the clutch mechanism rotates along with the small screw rod 5 (see figure 7).
When the hook slide block 6 moves to the joint of the large screw rod 4 and the small screw rod 5 on the large screw rod 4, the hook slide block 6 is gradually sleeved on the base 7, the positioning block 601 at the front end of the hook slide block 6 is firstly contacted with the connecting sleeve 8 of the clutch mechanism and pushes the connecting sleeve 8 to compress the spring until the connecting sleeve 8 rotates to the positioning groove 801 corresponding to the positioning block 601, and the connecting sleeve 8 is combined with the hook slide block 6 (see fig. 8). Because the hook sliding block 6 is combined with the connecting sleeve 8, and the limiting block 701 and the limiting groove are arranged between the connecting sleeve 8 and the base 7, after the connecting sleeve 8 is combined with the hook sliding block 6, the clutch mechanism cannot rotate, and the clutch mechanism moves from left to right along the small screw rod 5. At the moment, the hook sliding block 6 is not separated from the large screw rod 4, the clutch mechanism starts to move, and the expansion and contraction of the spring can make up the problem that the two move at different speeds.
After the hook slide block 6 is separated from the large screw rod 4, the hook slide block 6 moves on the small screw rod 5 through the clutch mechanism (see fig. 9).
Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art can change, add or replace the above examples within the scope of the present invention.
