Technical Field
[0001] This utility model relates to the field of soft curtain door technology, and in particular to a multifunctional constant speed intelligent soft curtain door. Background Technology
[0002] In modern industrial production, commercial venues, and various building environments, the requirements for the functionality and intelligence of doors are increasing. As a device commonly used to separate spaces, block dust, regulate temperature, and ensure passage, soft curtain doors play an important role in different scenarios. In order to better adapt to diverse usage needs, such as fast passage, precise control, and stable operation, the development of soft curtain doors with multi-functional, constant speed, and intelligent features has become an industry trend, aiming to provide more efficient, convenient, and reliable space separation and environmental control solutions.
[0003] Traditional PVC curtain doors typically employ a simple roller and motor drive system. The roller is usually installed horizontally above the door, with the PVC curtain wrapped around it. The motor is connected to the roller via a chain or belt, which drives the roller to rotate and roll up and down the PVC curtain.
[0004] However, existing soft curtain doors suffer from poor curtain stability during operation. Due to the lack of effective guiding and limiting structures, the curtain is prone to swaying, shifting, or even twisting when the soft curtain door is opened and closed, especially in windy environments or when it is frequently and rapidly opened and closed. This phenomenon is more pronounced, which not only affects the normal use of the soft curtain door and reduces its service life, but also leads to safety hazards. Therefore, a multi-functional constant speed intelligent soft curtain door is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a multi-functional constant-speed intelligent soft curtain door, which aims to improve the problem in the prior art where the curtain fabric is prone to shaking, shifting or even twisting when the soft curtain door is opened and closed, thus reducing its service life.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A multi-functional constant-speed intelligent soft curtain door includes a support frame, a support frame fixedly connected to the top of the support frame, a roller column rotatably connected inside the support frame, a drive column fixedly connected inside the roller column, a fixing screw inside the roller column, and the roller column and the drive column connected by the fixing screw. A curtain is provided on the outer wall of the roller column. A radar is fixedly connected to one side of the support frame, an infrared beam passes through the inside of the support frame, and the radar and the infrared beam are electrically connected. A drive component is provided at one end of the drive column, and a limit component is provided on the outer wall of the curtain.
[0008] The drive assembly includes a motor, one side of which is fixedly connected to one end of the transmission column. The output end of the motor is connected to one end of the transmission column. The outer wall of the motor is fixedly connected to the inside of the support frame. A control box is fixedly connected to one side of the support frame. A connecting wire is electrically connected inside the motor, and one end of the connecting wire is electrically connected to the inside of the control box.
[0009] As a further description of the above technical solution:
[0010] The limiting component includes a wind-resistant strip, which is internally fixedly connected to the outer wall of the curtain.
[0011] As a further description of the above technical solution:
[0012] The support frame has a sliding groove inside, and a slider is fixedly connected to one side of the wind-resistant strip.
[0013] As a further description of the above technical solution:
[0014] The wind-resistant strip is internally connected to a sliding column, and the slider is internally connected to the sliding groove.
[0015] As a further description of the above technical solution:
[0016] A spring is fitted on the outer wall of the sliding column, and the bottom end of the spring is fixedly connected to the inside of the wind-resistant strip.
[0017] As a further description of the above technical solution:
[0018] The tops of both the sliding column and the spring are in contact with the outer wall of the scroll.
[0019] This utility model has the following beneficial effects:
[0020] 1. In this utility model, the control box issues a command, which transmits an electrical signal through the connecting line to drive the motor to rotate. The motor drives the transmission column, which in turn drives the roller column. At the same time, the slider on one side of the wind-resistant strip slides in the groove inside the support frame, achieving a stable lifting and lowering effect for the curtain. This solves the problem that the curtain is prone to shaking, shifting, or even twisting when the soft curtain door is opened and closed, which reduces its service life and thus improves the stability of the soft curtain door.
[0021] 2. In this utility model, when the curtain rises to its limit position, the roller applies pressure to the sliding column inside the anti-wind strip. After the spring contracts, it uses its own elasticity to drive the anti-wind strip and the curtain back to their original positions, thus achieving an effective buffering effect on the curtain. This solves the problem that traditional soft curtain doors are easily damaged by the large impact force when the curtain reaches its limit position, thereby improving the service life of the curtain.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Reference Figures 1-3 This utility model provides an embodiment of a multi-functional constant-speed intelligent soft curtain door, including a support frame 1, which supports the entire platform structure. A support frame 2 is fixedly connected to the top of the support frame 1. A roller column 3 is rotatably connected inside the support frame 2. A transmission column 4 is fixedly connected inside the roller column 3. A fixing screw 5 is provided inside the roller column 3. The roller column 3 and the transmission column 4 are connected by the fixing screw 5 to ensure that the two rotate together. A curtain 9 is provided on the outer wall of the roller column 3. The transmission column 4 is driven by a drive component to move the curtain 9 up and down, thereby realizing the opening and closing of the soft curtain door. A radar 15 is fixedly connected to one side of the support frame 1. An infrared beam is passed through the support frame 1. The radar 15 and the infrared beam are electrically connected. A drive component is provided at one end of the transmission column 4. A limit component is provided on the outer wall of the curtain 9.
[0031] The drive assembly includes a motor 6, one side of which is fixedly connected to one end of the transmission column 4. The output end of the motor 6 is connected to one end of the transmission column 4. When the motor 6 starts, it drives the transmission column 4 to rotate, thereby driving the roller column 3 to rotate. The outer wall of the motor 6 is fixedly connected to the inside of the support frame 2. A control box 7 is fixedly connected to one side of the support frame 1. A connecting wire 8 is electrically connected inside the motor 6. One end of the connecting wire 8 is electrically connected to the inside of the control box 7. The electrical connection of the motor 6 is connected to the control box 7 through the connecting wire 8. The control box 7 issues commands and controls the start and stop of the motor 6. The limiting assembly includes a wind-resistant strip 10, which is fixedly connected to the outer wall of the curtain 9. The limiting assembly includes a wind-resistant strip 10, which is fixedly connected to the outer wall of the curtain 9. A sliding groove 11 is opened inside the support frame 1. A slider 12 is fixedly connected to one side of the wind-resistant strip 10. Through the cooperation of the slider 12 and the sliding groove 11, the curtain 9 remains stable during the lifting and lowering process and will not deviate.
[0032] Specifically, during the use of this flexible curtain door, when it is necessary to open or close the flexible curtain door, the operator issues a command through the control box 7. The control box 7 transmits an electrical signal to the motor 6 through the connecting line 8. The motor 6 starts and drives the transmission column 4 to rotate through electric drive. Since the roller column 3 and the transmission column 4 are connected by fixing screws 5, the rotation of the transmission column 4 will drive the roller column 3 to rotate inside the support frame 2. During operation, when the roller column 3 rotates clockwise, the curtain 9 is gradually rolled up, and the flexible curtain door rises and opens. At this time, when the roller column 3 rotates counterclockwise, the curtain 9 is gradually lowered, and the flexible curtain door descends and closes. The slider 12 and the sliding groove 11 inside the support frame 1 play a key role. The sliding groove 11 allows the slider 12 to slide smoothly and stably along its internal trajectory without generating resistance, which can effectively prevent the curtain 9 from deviating or being pulled during the lifting and lowering process.
[0033] Reference Figure 1 , Figure 3 and Figure 4 The wind-resistant strip 10 has a sliding column 13 inside, and the slider 12 is slidably connected inside the slide groove 11. The outer wall of the sliding column 13 is fitted with a spring 14. The function of the spring 14 is to provide elastic support and ensure that the wind-resistant strip 10 can stably contact the roller column 3 during the movement, and to buffer the curtain 9. The bottom end of the spring 14 is fixedly connected inside the wind-resistant strip 10, and the top ends of the sliding column 13 and the spring 14 are in contact with the outer wall of the roller column 3.
[0034] Specifically, during the process of the curtain 9 being rolled up, when the curtain 9 rises to its top limit position, the wind-resistant strip 10 on the outer wall of the curtain 9 will come into contact with the outer wall of the roller 3. When the wind-resistant strip 10 comes into contact with the outer wall of the roller 3, it can effectively absorb some of the impact force. As the roller 3 continues to rotate, it will apply a certain pressure to the sliding column 13 inside the wind-resistant strip 10, causing it to slide into the wind-resistant strip 10. At the same time, the roller 3 will compress the spring 14. When the roller 3 reaches the predetermined position, the spring 14 will rely on its own elasticity to restore its state and bring the wind-resistant strip 10 and the curtain 9 back to their original positions, ensuring that the curtain 9 can be restored to its neat state when the operation of the soft curtain door is completed, and avoiding damage caused by impact, thereby improving the service life of the soft curtain door.
[0035] Working Principle: When using the flexible curtain door, the operator issues a command through the control box 7 to open or close it. The control box 7 transmits an electrical signal to the motor 6 via the connecting cable 8. The motor 6 starts and drives the transmission column 4 to rotate. Since the roller column 3 and the transmission column 4 are connected by fixing screws 5, the rotation of the transmission column 4 will drive the roller column 3 to rotate inside the support frame 2. When the roller column 3 rotates, the curtain 9 on its outer wall will roll up or down with the rotation of the roller column 3. When the roller column 3 rotates clockwise, the curtain 9 is gradually rolled up, and the flexible curtain door rises and opens. When the roller column 3 rotates counterclockwise, the curtain 9 is gradually lowered, and the flexible curtain door descends and closes. During this process, the slider 12 on one side of the wind-resistant strip 10 will slide in the slide groove 11 inside the support frame 1, which makes the curtain 9 only move along the slide groove 11 during the lifting and lowering process. The directional movement ensures the straightness and stability of the curtain 9's operation. Simultaneously, during the retraction of the curtain 9, when it rises to its top limit position, the wind-resistant strip 10 on the outer wall of the curtain 9 contacts the outer wall of the roller 3. This causes the roller 3 to apply pressure to the sliding column 13 inside the wind-resistant strip 10, causing it to slide into the wind-resistant strip 10. At the same time, the roller 3 compresses the spring 14, causing it to contract. Then, through the elasticity of the spring 14, the wind-resistant strip 10 and the curtain 9 return to their original positions, thus effectively buffering the curtain 9.
[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
