Description

Technical Field

[0001] This utility model relates to the field of curtain manufacturing technology, and in particular to a convenient electric curtain tail plug structure. Background Technology

[0002] With the rapid development of the smart home industry and people's increasing pursuit of a high quality of life, electric curtains are now widely used. Electric curtains use the rotation of a motor to drive an external winding structure to roll up the curtain fabric.

[0003] Chinese Patent Publication (Announcement) No.: CN213743179U, Patent Title: A Wear-Resistant Electric Roller Blind, which discloses the following technical solution: "

[0004] To achieve the above-mentioned objective, this utility model provides the following technical solution: a wear-resistant electric roller blind, including a roller tube and a tubular motor disposed inside the roller tube. One end of the tubular motor is a travel head that protrudes outside the roller tube, and the other end of the tubular motor is a drive head that is linked with the roller tube. A crown that is linked with the roller tube is also movably disposed at one end of the tubular motor corresponding to the travel head. A friction-reducing component that can reduce friction is provided between the contact surface of the crown and the travel head." The technical solution achieves the following effect: "

[0005] Compared with the prior art, the beneficial effect of this utility model is that: this utility model adopts a friction-reducing component that can reduce friction between the crown and the travel head. The friction coefficient between the crown and the travel head is reduced by the friction-reducing component, which also avoids wear between the crown and the travel head and extends the service life of the electric blind."

[0004] However, “

[0019] Please refer to Figure 1-3 ...A linkage wheel 9 is rotatably connected to the other mounting bracket 4. This linkage wheel 9 is adapted to the inner diameter of the roller tube, so that the other end of the roller tube 1 is rotatably mounted on the other mounting bracket 4 via the linkage wheel 9. It can be seen that if the tubular motor inside the roller tube malfunctions and needs to be disassembled, the mounting bracket can only be removed from its fixed wall, and then the roller tube can be taken out from the linkage wheel. This method of replacing the tubular motor, which requires disassembling the entire electric curtain set, is not only time-consuming but also affects the overall aesthetics of the wall and needs improvement. Summary of the Invention

[0005] The purpose of this utility model is to provide a convenient electric curtain tail plug structure to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical measures: a conveniently detachable electric curtain tail plug structure, including a left cover and a right cover connected to the curtain cover of the electric curtain, characterized in that: the left cover is connected to one end of an aluminum tube through a motor front plug assembly, and the right cover is connected to the other end of the aluminum tube through a tail plug assembly; a pin is provided on the left cover, the pin being used to connect to the connecting inner cavity of the motor front plug assembly; the tail plug assembly includes a square shaft fixing seat and a bearing tail plug, the bearing tail plug containing a square shaft, the square shaft being fixed... The seat is provided with a bushing with a square cavity, and a rolling bearing is tightly fitted on the outside of the bushing. An opening limiting block is provided on the right side cover. The opening limiting block is used to connect the square shaft inside the bearing tail insert. The square shaft is interference-fitted with the square cavity of the square shaft fixing seat. The square shaft fixing seat is provided with a small C-shaped disc wall. The small C-shaped disc wall is movably installed in the C-shaped circular groove of the bearing tail plug cap. The bearing tail plug cap is provided with a bearing outer cover that fits the rolling bearing. The bearing tail plug cap is provided with a large C-shaped disc wall that covers the small C-shaped disc wall.

[0007] Compared with existing technologies, the advantages of this invention are as follows: By providing a pin on the left side cover to connect to the inner cavity of the motor front insertion assembly, and through the cooperation of the square shaft fixing seat, bearing tail plug, bearing tail plug cap, and right side cover of the tail insertion assembly, when the tubular motor assembly inside the aluminum tube malfunctions and needs to be disassembled, simply rotating the bearing tail plug cap allows the tail insertion assembly to be removed from the right side cover, thus removing the entire aluminum tube from the entire electric curtain set without damaging its fixed wall appearance. This novel structure makes disassembly and assembly easier and less strenuous when replacing the tubular motor inside the aluminum tube, without affecting the overall aesthetics of the wall.

[0008] As an improvement of this utility model, a friction block is provided on the square shaft fixing seat, and a stop block is provided on the bearing tail plug cap. The purpose of this design is that when the stop block rotates onto the friction block, the bearing tail plug cap can remain stationary under the action of friction.

[0009] As an improvement to this utility model, the pin is cross-shaped, and the connecting cavity is star-shaped. The purpose of this design is that the cross-shaped pin can be inserted into the star-shaped connecting cavity at three different angles, making it easier to mate and install the motor assembly inside the aluminum tube with the motor front insertion assembly.

[0010] As an improvement of this utility model, a handle is provided on the bearing tail plug cap. The purpose of this design is to allow the bearing tail plug cap to be rotated via the handle, making it easier to install and remove the aluminum tube.

[0011] As an improvement to this utility model, the square shaft fixing seat passes through the bearing tail insert and is fixed by a snap ring. The purpose of choosing this design is to facilitate installation and disassembly through the snap ring structure. Attached Figure Description
