Description

Technical Field

[0001] This utility model relates to the field of roller shutter technology, and more specifically, to a movable side panel of a roller shutter door. Background Technology

[0002] Roller shutters are a common building component, widely used in shops, garages, warehouses and other places. The main advantage of roller shutters is their high space utilization, especially in places with large door openings that need to be opened and closed frequently. With the development of technology, the materials for roller shutters have gradually expanded from traditional metal and wood to newer materials such as lighter and more durable aluminum alloy and PVC.

[0003] However, the center hole of the side panel shaft in existing roller shutter doors is fixed. As the thickness of the door panel rolls on the roller shaft, the connection between the curtain panel and the track will not be perpendicular, causing the roller shutter and the track to rub against each other. This will also increase resistance and noise during operation. Long-term friction will also cause severe wear on the roller shutter or track, affecting its service life.

[0004] Therefore, there is an urgent need for a technology that can solve the problem of wear caused by the curtain slats not being perpendicular to the track during the rolling of roller shutter doors. Utility Model Content

[0005] In view of this, this utility model addresses the shortcomings of the prior art by proposing a movable side panel for a roller shutter door, aiming to solve the problem of wear caused by the curtain slats not being perpendicular to the track during the rolling process of the shutter door.

[0006] In one aspect, this utility model provides a movable side panel for a high-speed roller shutter door, comprising:

[0007] Fixed unit and floating limit unit;

[0008] A fixing unit, the fixing unit including a fixing side plate, the fixing side plate being fixedly connected to the wall, and a first limiting hole being provided in the center of the fixing side plate, the first limiting hole being used for the displacement of the moving plate;

[0009] A floating limiting unit is disposed on the fixed side plate. The floating limiting unit is used to limit the roller shutter. The floating limiting unit includes a plurality of slide rails disposed on the fixed side plate, sliders disposed on the plurality of slide rails, the number of sliders corresponding to the number of slide rails, and a movable plate disposed on the sliders.

[0010] Furthermore, it also includes: a traction unit, which is disposed on the movable plate and is used to pull the roller blind to roll or stretch. The traction unit includes a bearing disposed on the movable plate and a roller disposed on the bearing.

[0011] Furthermore, the floating limiting mechanism also includes a guide rail groove, which is disposed below the fixed unit and is used to limit the rolling shutter when it is rolled up or stretched.

[0012] Furthermore, the floating limiting mechanism also includes a noise reduction unit disposed inside the guide rail groove.

[0013] Furthermore, a second limiting hole is provided on the left side of the fixed side plate, which is used to fix and connect the wall.

[0014] Furthermore, the fixing unit also includes a wall mounting bracket, which is connected to the wall.

[0015] Furthermore, the wall mounting bracket is provided with several third limiting holes.

[0016] Furthermore, the fixed side plate is also provided with limiting plates, which are respectively provided on the upper side, right side and lower side of the fixed side plate, and the limiting plates are used to fix and connect the outer shell.

[0017] Furthermore, a plurality of rivet nuts are provided around the first limiting hole, and the rivet nuts are used to fix and connect the outer shell.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model is equipped with a floating limit unit. Through the cooperation of the slider and the slide rail, the moving plate maintains a stable moving state during the movement process, ensuring that the moving plate can run along the predetermined track. This prevents the curtain from being non-perpendicular to the track due to the thickness of the curtain roller. With the floating limit unit, the curtain can always maintain a perpendicular state to the track, thereby ensuring that the curtain will not rub against the guide rail when entering the track. This reduces noise and extends the service life of the curtain and track, reducing the maintenance frequency and cost of the roller shutter door.

[0019] This invention extends the service life of roller shutters, ensures that the shutter curtain is always perpendicular to the track, reduces friction noise, improves the stability of roller shutters, and reduces the cost and frequency of later maintenance. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0029] Roller shutters are a common building component, widely used in shops, garages, warehouses, and other places. However, the existing side panel shaft center hole is fixed. As the door slats roll on the roller 402, the connection between the slats and the track becomes non-perpendicular, causing the roller shutter 5 to be misaligned with the track. This results in wear on the slats and track, not only causing noise but also damaging the slats and track over time, affecting their service life. Therefore, it is necessary to design a roller shutter 5 with movable side panels to ensure that the slats and track always remain perpendicular, reducing noise and wear.

[0030] See Figure 1 , Figure 2 As shown, this embodiment provides a movable side panel for a high-speed roller shutter door, including a fixing unit and a floating limiting unit 2;

[0031] The fixing unit includes a fixing side plate 1, which is fixedly connected to the wall. A first limiting hole 101 is provided in the center of the fixing side plate 1, which is used for the displacement of the moving plate 203.

[0032] A floating limit unit 2 is installed on the fixed side plate 1. The floating limit unit 2 is used to limit the roller shutter 5. The floating limit unit 2 includes a plurality of slide rails 201 installed on the fixed side plate 1, a slider 202 installed on the plurality of slide rails 201, the number of sliders 202 corresponding to the number of slide rails 201, and a movable plate 203 installed on the slider 202.

[0033] Specifically, the fixed side plate 1 is fixedly connected to the wall. The fixed side plate 1 is provided with a slide rail 201 and a slider 202. The movable plate 203 is provided on the slider 202. The movable plate 203 can slide back and forth on the slide rail 201. When the curtain rises or falls, the movable plate 203 can slide to ensure that the curtain is always perpendicular to the track and does not contact the track.

[0034] Understandably, by fixing the fixed side plate 1 to the wall, the stability and structural support of the system are ensured. The slide rail 201 on the fixed side plate 1 provides a stable and smooth sliding path. When the curtain rises or falls, the moving plate 203 slides on the slide rail 201 with the movement of the curtain, ensuring that the curtain always remains perpendicular to the track. Since the curtain remains perpendicular to the track throughout the entire lifting process and does not directly contact the track, the resistance and wear caused by friction are reduced, extending the service life of the curtain and the track. It also reduces noise caused by friction, improving the comfort of using the roller shutter door. The cooperation between the moving plate 203 and the slider 202 makes the movement of the curtain smoother, avoiding shaking or jamming of the curtain during lifting, improving the reliability of the curtain system. Even with frequent use, it can still maintain efficient operation. In addition, since the curtain always remains perpendicular to the track during lifting, less power is required for lifting, effectively reducing energy consumption and improving the durability of the system. Since the curtain does not directly contact the track, wear and tear during long-term use is reduced, which not only lowers the frequency of maintenance and replacement but also saves maintenance costs.

[0035] In some embodiments of this application, combined with Figure 4 As shown, it also includes: a traction unit 4, which is disposed on the movable plate 203. The traction unit 4 is used to pull the roller blind 5 to roll or stretch. The traction unit 4 includes a bearing 401 disposed on the movable plate 203 and a roller 402 disposed on the bearing 401.

[0036] In some embodiments of this application, a roller blind 5 is also included, which is disposed on the roller shaft 402 and fixedly connected to the roller shaft 402.

[0037] Specifically, a bearing 401 is provided on the movable plate 203, and a roller 402 is provided on the bearing 401. The traction unit 4 is driven by an external motor. When the motor drives, the bearing 401 rotates, causing the roller 402 to rotate, thereby controlling the roller blind 5 to rise or fall. When the roller blind 5 rises or falls, the thickness of the roller 402 will change accordingly, which will also pull the movable plate 203 to move, so that the roller blind 5 is always perpendicular to the guide rail.

[0038] Understandably, when the motor starts, the bearing 401 drives the roller 402 to rotate, thereby controlling the lifting and lowering process of the roller shutter 5. As the thickness of the roller 402 changes when the roller shutter 5 rises or falls, it will correspondingly pull the moving plate 203 to move on the slide rail 201, thus ensuring that the roller shutter 5 always remains perpendicular to the guide rail. This improves the stability and operating efficiency of the roller shutter 5 and avoids the jamming or shaking that may occur in traditional roller shutter doors. The cooperation between the bearing 401 and the roller 402 makes the lifting and lowering process smoother, reducing friction and noise. The change in the thickness of the roller 402 can automatically pull the moving plate 203 to move, so that the roller shutter 5 always remains perpendicular to the guide rail during the lifting and lowering process. This reduces the possibility of the roller shutter 5 tilting or deviating from the guide rail during the lifting and lowering process, effectively reducing friction and wear between the roller shutter 5 and the guide rail, extending the service life of the equipment, and reducing maintenance and replacement costs. In addition, the roller shutter door has low operating friction, and the power required to drive the motor is reduced, which not only reduces energy consumption but also reduces the load on the motor, thereby extending the service life of the roller shutter door and reducing operating costs.

[0039] In some embodiments of this application, the floating limiting mechanism further includes a guide rail groove 204, which is disposed below the fixed unit and is used to limit the rolling shutter 5 when it is rolled up or stretched.

[0040] Understandably, when the motor drives the curtain, it will rise or fall along the guide rail groove 204. The floating limit unit 2 can make the roller 402 move at all times, so that the curtain always remains perpendicular to the guide rail. The curtain does not contact the entrance of the guide rail, reducing the friction noise generated during the raising and lowering of the curtain.

[0041] In some embodiments of this application, the floating limiting mechanism further includes a noise reduction unit 205 disposed inside the guide rail groove 204.

[0042] Specifically, when the curtain rises or falls, it slides along the preset path of the guide rail 204. A noise reduction unit 205 is provided inside the guide rail 204 to eliminate noise when the curtain rises or falls.

[0043] Understandably, traditional roller shutters rub against the guide rail groove 204 when they rise or fall, generating noise. If used for a long time, this will cause wear and tear and reduce their service life. The noise reduction unit 205 can not only reduce noise, but also play a certain role in buffering, preventing the door curtain from directly contacting the guide rail groove 204, increasing its service life, and reducing the number of maintenance times and costs.

[0044] In some embodiments of this application, a second limiting hole 102 is also provided on the left side of the fixed side plate 1, and the second limiting hole 102 is used to fix the wall.

[0045] Specifically, the fixed side plate 1 is equipped with a bearing 401, a roller 402, a curtain, etc. Especially when the curtain is rolled up, it will have a certain weight. Therefore, the second limiting hole 102 can make the fixed side plate 1 more firmly set on the wall and increase the load-bearing capacity.

[0046] It is understandable that the fixed side plate 1 is equipped with structures such as bearing 401, roller 402, and curtain. Especially when the curtain is rolled up, it will generate a certain weight. Therefore, the second limiting hole 102 can provide an additional fixing point, making the connection between the fixed side plate 1 and the wall more secure and enhancing the stability of the entire structure. Without the second limiting hole 102, a single fixing point may not be able to cope with the concentrated weight of the curtain and related components, which may cause the side plate to loosen or shift. Secondly, adding the second limiting hole 102 can effectively distribute the load, distributing the weight of the curtain to multiple fixing points on the wall, avoiding stress concentration on the wall or side plate caused by concentrated load, and reducing the risk of structural fatigue and damage. In addition, the second limiting hole 102 can also improve the seismic performance of the overall structure, and enhance the safety and durability of the curtain.

[0047] In some embodiments of this application, combined with Figure 3 As shown, the fixing unit also includes a wall mounting bracket 3, which is connected to the wall.

[0048] In some embodiments of this application, the wall mounting bracket 3 is provided with a plurality of third limiting holes 301.

[0049] Understandably, the wall mounting bracket 3 is directly fixed to the wall. The wall mounting bracket 3 also has several third limiting holes 301. The third limiting holes 301 are used to fix the connecting parts of the side plate 1 through the third limiting holes 301 to connect to the wall.

[0050] In some embodiments of this application, the fixed side plate 1 is further provided with a limiting plate 104, which is respectively provided on the upper side, right side and lower side of the fixed side plate 1, and the limiting plate 104 is used to fix the outer shell.

[0051] Specifically, the wall mounting bracket 3 is fixed to the wall, the second limiting hole 102 of the fixed side plate 1 passes through the third limiting hole 301 of the wall mounting bracket 3 and connects to the wall, and the fixed side plate 1 is provided with three limiting plates 104, which are used to fix and connect the roller shutter door shell.

[0052] Understandably, the three limiting plates 104 set on the fixed side plate 1 provide fixing points for the roller shutter door shell. The function of the limiting plates 104 is to fix the roller shutter door shell and prevent it from falling off or shifting during use. The setting of the three limiting plates 104 also allows the roller shutter door shell to be evenly fixed on the side plate, avoiding excessive local stress caused by concentrated load, reducing deformation and damage to the shell and the overall structure, and extending service life.

[0053] In some embodiments of this application, a plurality of rivet nuts 103 are provided around the first limiting hole 101, and the rivet nuts 103 are used to fix and connect the outer shell.

[0054] Specifically, a limiting plate 104 is provided on the fixed side plate 1. At the same time, rivet nuts 103 are provided around the first limiting hole 101 on the fixed side plate 1. The roller shutter door shell is fixedly connected to the limiting plate 104, and the shell is fixedly connected to the side with rivet nuts 103, which can make the shell more firmly fixed on the fixed side plate 1.

[0055] Understandably, a limiting plate 104 is provided on the fixed side plate 1, and rivet nuts 103 are provided around the first limiting hole 101 on the fixed side plate 1. The limiting plate 104 provides a stable fixing point for the roller shutter door shell, ensuring that the shell will not shift or fall off during use. The rivet nuts 103 further enhance the connection strength between the shell and the fixed side plate 1. As a high-strength fastener, the rivet nuts 103 can provide additional tensile and tightening forces, making the roller shutter door shell more firmly fixed to the fixed side plate 1, and ensuring that the connection part can withstand long-term loads and vibrations and impacts during use, reducing the risk of loose connection failures. The rivet nuts 103 also make the disassembly and assembly of the shell more convenient, effectively reducing maintenance costs and time. Maintenance personnel can quickly and safely complete maintenance without worrying about damaging the structural integrity.

[0056] The general flow of this embodiment is as follows:

[0057] Fixed Unit: The fixed unit includes a wall mounting bracket 3 and a fixed side plate 1. The wall mounting bracket 3 is directly fixed to the wall. The fixed side plate 1 is connected to the wall through the second limiting hole 102 and the third limiting hole 301 on the wall mounting bracket 3. The rivet nut 103 and the limiting plate 104 on the fixed side plate 1 are used to fix the roller shutter door shell.

[0058] Floating limiting unit 2: The floating limiting unit 2 is set on the fixed side plate 1. The floating limiting unit 2 includes a slide rail 201, a slider 202 set on the slide rail 201, and a movable plate 203 set on the slider 202.

[0059] Traction unit 4: Traction unit 4 is mounted on the movable plate 203. Traction unit 4 includes bearing 401 and roller 402. Traction unit 4 is driven by an external motor.

[0060] Roller blind 5: Installed on roller 402;

[0061] When the motor starts, the bearing 401 rotates, driving the roller 402 to rotate. The roller blind 5 rises or falls by rotating in the direction of rotation. When the roller blind 5 rises, the thickness of the roller 402 increases and its weight increases. At this time, the moving plate 203 is displaced to keep the blind perpendicular to the guide rail. When the roller blind 5 falls, the thickness of the roller 402 decreases and its weight decreases. At this time, the moving plate 203 is displaced to keep the blind perpendicular to the guide rail.

[0062] In one of the above embodiments, the present invention is provided with a floating limiting unit 2. Through the cooperation of the slider 202 and the slide rail 201, the moving plate 203 maintains a stable moving state during the movement process, ensuring that the moving plate 203 can run along the predetermined track, and that the connection between the curtain and the track will not be non-perpendicular due to the thickness of the curtain roller 402. With the setting of the floating limiting unit 2, the curtain can always maintain a perpendicular state to the track, thereby ensuring that the curtain will not rub against the guide rail when entering the track, reducing noise, increasing the service life of the curtain and the track, and reducing the maintenance frequency and cost of the roller shutter door.

[0063] This invention extends the service life of roller shutters, ensures that the shutter curtain is always perpendicular to the track, reduces friction noise, improves the stability of roller shutters, and reduces the cost and frequency of later maintenance.

[0064] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
