Description

Technical Field

[0001] This utility model relates to the field of manufacturing technology of automatic curtains, and in particular to a honeycomb curtain with a centrally located motor and pull cord structure. Background Technology

[0002] Honeycomb blinds, also known as accordion blinds, are shaped like an accordion when pulled open, resembling a honeycomb. Their unique honeycomb structure allows air to be stored in the hollow layers, maintaining a constant indoor temperature. Honeycomb blinds generally consist of an outer frame, a motor assembly for power, a foldable curtain body, and a pull cord. The curtain body comprises multiple sequentially connected folding units, each with a through-hole. The pull cord passes through these holes, allowing the lower end of the curtain to be pulled up or down, folding the units together or unfolding them, thus opening and closing the honeycomb blind.

[0003] Chinese Patent Publication (Announcement) No.: CN112539024B, Patent Title: A Multipurpose Honeycomb Curtain, which discloses the technical solution of "

The top of the second honeycomb curtain is adsorbed and connected to the other side of the liftable traction beam through at least one set of second magnetic components", achieving the technical effect of "

[0017] The beneficial effects of the present invention are as follows... The present invention, through the snap-fit ​​connection between the honeycomb curtain and the outer frame, makes the first honeycomb curtain and the second honeycomb curtain easier to disassemble and replace".

[0004] Although the first and second honeycomb blinds of this structure can be easily disassembled and replaced, since the first and second honeycomb blinds are two separate blinds, they require different motors to drive them. The layout of the pull cords that drive the blinds to move up or down is different from that of a single honeycomb blind. Therefore, the market urgently needs a motor and pull cord structure suitable for two honeycomb blinds. Utility Model Content

[0008] As an improvement of this utility model, a guide sleeve is provided in the middle of the pull rope. The purpose of this design is to improve the stability of the pull rope and reduce its friction and wear.

[0009] As an improvement to this utility model, the left fixing seat for the bottom beam rope includes a base, a screw rod on the base, a movable slider sleeved on the screw rod, and a pull rope connected to the movable slider. The purpose of this design is to allow for easy adjustment of the bottom beam's height on one side when it is not parallel to the lower window sill, by rotating the screw rod, thus making the bottom beam level with the lower window sill.

[0010] As an improvement to this utility model, a rotating opening is provided on the left fixing seat of the bottom beam rope winding. The purpose of this design is that the rotating opening is used to assemble the adjusting handle, and rotating the adjusting handle causes the screw to rotate synchronously.

Detailed Implementation

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Example 1

[0022] Please refer to Figure 1-5 .

[0023] This embodiment provides a honeycomb blind with a central motor and pull cord structure, including a dual-head motor 2 (also called a central motor because it is located in the middle) located in the middle of the outer frame 1 of the blind. The dual-head motor 2 is powered by a lithium battery bar 25. The dual-head motor 2 has a left output head 3 integrally provided on the left end of the main body and a right output head 4 integrally provided on the right end of the main body.

[0024] In the embodiments of this utility model application, please refer to Figure 1 and Figure 3 The left output head 3 is sequentially connected to a first rope winder 6, a second rope winder 7, and a third rope winder 8 via a synchronous shaft 5. The first rope winder 6 is connected to the central beam rocker wheel 10 via a pull rope 9, the second rope winder 7 is connected to the right rope winder fixed seat 11 of the central beam via a pull rope 9, and the third rope winder 8 is connected to the left rope winder fixed seat 12 of the central beam via a pull rope 9.

[0025] Furthermore, the right output head 4 is sequentially connected to a fourth rope winder 13, a fifth rope winder 14, and a sixth rope winder 15, which can rotate synchronously, via a synchronous shaft 5. The fourth rope winder 13 is connected to the bottom beam rocker wheel 16 via a pull rope 9, the fifth rope winder 14 is connected to the bottom beam left rope winder fixed seat 17 via a pull rope 9, and the sixth rope winder 15 is connected to the bottom beam right rope winder fixed seat 18 via a pull rope 9.

[0026] It should be noted that the middle beam rocker 10 and the bottom beam rocker 16 are manually operated to pull the upper curtain 28 and the lower curtain 29. The bottom end of the upper curtain 28 is provided with a middle beam 26, and the bottom end of the lower curtain 29 is provided with a bottom beam 27.

[0027] In the embodiments of this utility model application, please refer to Figure 4 A guide sleeve 19 is provided in the middle of the pull rope 9. The guide sleeve 19 is used to improve the stability of the pull rope 9 and reduce the friction and wear of the pull rope 9. Several through holes are provided in the guide sleeve 19. Different pull ropes 9 pass through different through holes, which can change direction by 90 degrees or not. The pull rope 9 is used to pull the lower end of the curtain up or down.

[0028] In the embodiments of this utility model application, please refer to Figure 5 The left fixing seat 17 for the bottom beam cord includes a base 20, on which a screw 21 is mounted. A movable slider 22 is sleeved on the screw 21, and a pull rope 9 is connected to the movable slider 22. With this structure, by setting the left fixing seat 17 for the bottom beam cord, when the bottom beam of the electric curtain is not parallel to the lower window edge, the screw 21 can be rotated to adjust the height of one side of the bottom beam, making it level with the lower window edge, thus simplifying operation.

[0029] Furthermore, a rotating opening 23 is provided on the left fixing seat 17 of the bottom beam rope winding. The rotating opening 23 is used to assemble the adjusting handle. After rotating the adjusting handle, the screw 21 rotates synchronously.
