Description

Technical Field

[0001] This utility model belongs to the technical field of smoke curtains, specifically relating to an octagonal roller for smoke curtains. Background Technology

[0002] In existing technology, the rollers used for smoke curtains are generally circular, used to roll up the curtain. They include a strip-shaped drive motor, a circular drum, and a tail plug. During installation, the drive motor is placed inside the drum, and both ends of the drum are fixedly connected to the crown of the drive motor (the crown is movably connected to the drive motor) by the tail plug. Because the drum needs to be fixedly connected to the drive motor's rotating wheel (so that the drive motor can drive the drum to rotate), the rotating wheel of the drive motor, which extends deep into the drum, also needs to be screwed to the drum. The installation process requires pre-measurement and marking on the outer wall of the drum, and finally drilling holes and screwing at the marked points to fix the tail plug, rotating wheel, and crown to the drum. The installation process is relatively cumbersome and has a certain degree of difficulty. Therefore, the purpose of this utility model is to provide an octagonal roller for smoke curtains that is easy to install and has a stable structure. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, this utility model provides an octagonal roller for smoke curtains.

[0004] The technical solution of this utility model is as follows: an octagonal roller for smoke curtain, including a drive motor, an octagonal roller and a tail plug. One end of the drive motor is provided with a rotating wheel, and the other end has a power supply line extending out. One end of the power supply line is provided with a crown. The drive motor is disposed inside the octagonal roller. One end of the octagonal roller is snapped and fixed to the tail plug, and the other end is snapped and fixed to the crown of the drive motor.

[0005] Furthermore, the insertion part of the tail plug is octagonal in shape, and its diameter is no greater than the inner diameter of the octagonal drum; the tail plug is snapped onto one end of the octagonal drum through its insertion part.

[0006] Furthermore, the drive motor's rotating wheel is octagonal in shape, with a diameter not greater than the inner diameter of the octagonal drum, and the rotating wheel can be snapped into the inside of the octagonal drum.

[0007] Furthermore, the crown of the drive motor is provided with a stepped portion, which is octagonal in shape. The diameter of the stepped portion is not greater than the inner diameter of the octagonal drum, and the crown can be snapped onto one end of the octagonal drum through its stepped portion.

[0008] Furthermore, the crown is movably connected to one end of the drive motor.

[0009] Furthermore, the drive motor has a shaft extending from one end of its power supply line, and a support plate is provided at the end of the shaft, with the end of the shaft being fixedly connected to the support plate.

[0010] Furthermore, one end of the tail plug is snapped into connection with an octagonal reel, and the other end is provided with a telescopic shaft. A bracket plate is provided at the end of the telescopic shaft, and the end of the telescopic shaft is fixedly connected to the bracket plate.

[0011] Furthermore, the aforementioned octagonal drum has several mounting holes spaced at equal intervals.

[0020] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The descriptions of the exemplary embodiments are merely illustrative and are in no way intended to limit the present invention or its application or use. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the present invention thorough and complete, and to fully express the scope of the present invention to those skilled in the art. It should be noted that, unless otherwise specifically stated, the relative arrangement of components and steps, the composition of materials, numerical expressions, and values ​​set forth in these embodiments should be interpreted as merely exemplary and not as limiting.

[0021] The terms "first," "second," and similar words used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different parts. Words such as "including" or "comprising" mean that the element preceding the word encompasses the element listed after it, and do not exclude the possibility of encompassing other elements as well. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0022] like Figure 1-4 As shown, an octagonal roller for smoke curtains includes a drive motor 2, an octagonal drum 1, and a tail plug 3. One end of the drive motor 2 is provided with a rotating wheel 201, and the other end has a power supply line 202 extending out. One end of the power supply line 202 is provided with a crown 203. The drive motor 2 is disposed inside the octagonal drum 1. One end of the octagonal drum 1 is snapped and fixed to the tail plug 3, and the other end is snapped and fixed to the crown 203 of the drive motor 2.

[0023] Specifically, the insertion part of the tail plug 3 is octagonal, and its diameter is no greater than the inner diameter of the octagonal drum 1; the tail plug 3 is snapped onto one end of the octagonal drum 1 through its insertion part.

[0024] Specifically, the drive motor 2's rotating wheel 201 is octagonal in shape, and its diameter is no larger than the inner diameter of the octagonal drum 1. The rotating wheel 201 can be snapped into the inside of the octagonal drum 1.

[0025] Specifically, the crown 203 of the drive motor 2 is provided with a step portion 204, which is octagonal in shape. The diameter of the step portion 204 is not greater than the inner diameter of the octagonal drum 1. The crown 203 can be snapped onto one end of the octagonal drum 1 through its step portion 204.

[0026] Specifically, Crown 203 is movably connected to one end of drive motor 2.

[0027] Specifically, the drive motor 2 has a shaft 205 extending from one end of its power supply line 22, and a bracket plate 4 is provided at the end of the shaft 205, and the end of the shaft 205 is fixedly connected to the bracket plate 4.

[0028] Specifically, one end of the tail plug 3 is snapped into the octagonal drum 1, and the other end is provided with a telescopic shaft 302. The end of the telescopic shaft 302 is provided with a bracket plate 4, and the end of the telescopic shaft 302 is fixedly connected to the bracket plate 4.

[0029] Specifically, the octagonal drum 1 has several mounting holes 101 spaced at equal intervals.

[0030] See Figure 2 , 3The installation process of the octagonal scroll is as follows: First, one end of the rotating wheel 201 of the drive motor 2 is inserted into the octagonal scroll 1. The outer diameter of the rotating wheel 201 matches the inner diameter of the octagonal scroll 1 and can be directly engaged longitudinally in the octagonal scroll 1. Then, the end of the octagonal scroll 1 at this end can be engaged and covered by the crown 203 movably connected to the drive motor 2. The end of the octagonal scroll 1 at the other end is engaged and fixed by the tail plug 3. After the octagonal scroll 1 with the drive motor 2 and the tail plug 3 installed is laterally limited at both ends by two support plates 4. The two support plates 4 respectively limit the rotation of the telescopic shaft 302 of the tail plug 3 and the rotating shaft 205 of the drive motor 2. Compared to traditional circular reels, circular drums require drilling holes after the drive motor 2 and tail plug 3 are installed to secure them to the tail plug 3, the rotating wheel 201, and the crown 203 with screws. This provides anchor points for the rotating wheel 201 to drive the drum's rotation, making the installation process more cumbersome and difficult. In this solution, the inner diameter of the octagonal drum 1 in the octagonal reel matches the outer diameter of the tail plug 3's insertion part 301, the rotating wheel 201, and the outer diameter of the crown 203's stepped part 204. After the drive motor 2 starts, the rotating wheel 201 can directly drive the drum to rotate without the need for screws. This makes overall installation convenient and simplifies the installation process of the smoke curtain.

[0031] As one embodiment of the octagonal roller 1, a number of mounting holes 101 can be pre-drilled on its wall along a straight line at equal intervals. Since the octagonal roller 1 is used to roll up the curtain in the smoke curtain, the top of the curtain needs to be fixedly connected to the octagonal roller 1. The mounting holes 101 can facilitate the installation and fixing of the curtain, eliminating the need to temporarily drill holes on the roller during on-site installation, which can further simplify the overall installation process of the smoke curtain.

[0032] The various embodiments of this utility model have now been described in detail. To avoid obscuring the concept of this utility model, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

[0033] The embodiments described above only illustrate some implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
