Detailed Description

As shown in fig. 1, the present embodiment is a double-open type retractable electric curtain rail, which has a retractable curtain rail housing and a retractable double-open pulling mechanism installed in the curtain rail housing.

In this embodiment, the curtain rail housing is composed of a large housing 8 and a small housing 9, wherein one end of the small housing 9 is coaxially inserted into the large housing 8, and the telescopic adjustment of the curtain rail housing is realized by adjusting the relative position of the large and small housings along the axial direction, so as to change the length of the curtain rail housing and adapt to the widths of different windows.

As shown in fig. 2, the double-open traction mechanism in this embodiment includes a motor transmission case 11, a tail bearing bracket 3, a left lead screw 4, a right lead screw 5, a transmission gear box 6, etc., wherein the motor transmission case 11 is connected to a motor 10, the motor transmission case is installed at the left end of the curtain rail housing, and the tail bearing bracket 3 is installed at the right end of the curtain rail housing. In the embodiment, the left screw rod 4 and the right screw rod 5 are both parallel to the axial direction of the curtain rail shell, the left end of the left screw rod 4 is connected with a motor transmission case 11, and the left screw rod 4 is connected with an output shaft of a motor 10 through the transmission of the motor transmission case 11; the right end of the right screw rod 5 is connected with the tail end bearing support 3; the left screw rod 4 is in transmission connection with the right screw rod 5 through a transmission gear box 6.

As shown in fig. 3, in the present embodiment, the transmission gear box 6 has a left gear 602 and a right gear 601 inside, wherein the left gear 602 is mounted on the left lead screw 4, the right gear 601 is mounted on the right lead screw 5, and the left and right gears are engaged with each other at the same rotation speed and in opposite rotation directions.

In the embodiment, a plurality of hook sliding blocks I1 in threaded connection with the left screw rod 4 are arranged on the left screw rod, a plurality of hook sliding blocks II 2 in threaded connection with the right screw rod are respectively arranged on the right screw rod 5, and the hook sliding blocks I and II can be respectively driven by the left screw rod and the right screw rod to move left and right along the axial direction of the left screw rod and the right screw rod.

A threaded hole I102 matched with the left screw rod 4 is formed in the hook sliding block I1, and a guide hole I103 corresponding to the right screw rod 5 is formed in the hook sliding block I; and a threaded hole II 202 matched with the right screw rod 5 is formed in the hook sliding block II 2, and a guide hole II 203 corresponding to the left screw rod 4 is formed in the hook sliding block II.

Guide wheels I101 are installed on two sides of a hook sliding block I1, the hook sliding block I1 is supported on two sides of a curtain rail shell through the guide wheels I101 on the two sides of the hook sliding block I, rail grooves I corresponding to the guide wheels I101 are formed on the two sides of the curtain rail shell, the rail grooves I are formed by splicing a large shell and a small shell, one half of the rail grooves I are formed on the large shell, and the other half of the rail grooves I are formed on the small shell (see figures 4 and 5); guide wheels II 201 are installed on two sides of a hook sliding block II 2, the hook sliding block II 2 is supported on two sides of a curtain rail shell through the guide wheels II 201 on two sides of the hook sliding block, rail grooves II corresponding to the guide wheels II 201 are formed in two sides of the curtain rail shell, the rail grooves II are formed by splicing a large shell and a small shell, one half of the rail grooves II are formed in the large shell, and the other half of the rail grooves II are formed in the small shell (see figures 6 and 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 a large shell and a small shell, 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 transmission gear box 6 moves axially along the left and right screw rods under the action of tension or pressure, and the positions of the transmission gear box 6 on the left and right screw rods are changed, so that the relative positions of the left and right screw rods are changed, and the length of the double-opening traction mechanism is finally changed to meet the installation requirements.
