Abstract
Description
Technical Field
[0001] This utility model relates to the field of roller shutter technology, and in particular to a high-speed roller shutter door with a reinforced guide structure. Background Technology
[0002] Roller shutters are doors with multiple articulated door panels linked together. They rotate up and down within fixed tracks, centered on a roller at the top of the door. Roller shutters are commonly used in shops, serving as horizontal partitions, similar to walls. High-speed roller shutters, also known as high-speed soft curtain doors, are a type of roller shutter. They are barrier-free isolation doors that can quickly rise and fall at speeds exceeding 0.6 meters per second. Their main functions are rapid opening and closing and rapid isolation, and they are widely used in many places.
[0003] Existing guide structures for high-speed rolling shutters have the following drawbacks: A vertical guide rail is typically installed on the side of the rolling shutter to guide it during opening and closing. Existing guide structures consist of ordinary guide rails and pulleys. After prolonged use, especially due to factors such as guide rail deformation from impacts and thermal expansion and contraction, the pulley assembly may fail to fit snugly against the guide groove on the inner wall of the guide rail. This causes deviation and wobbling during the opening and closing of the rolling shutter, affecting its rapid operation. Therefore, we propose a high-speed rolling shutter with a reinforced guide structure. Utility Model Content
[0004] The main objective of this invention is to provide a high-speed rolling shutter door with a reinforced guide structure. Through the guide mechanism, the guide wheel assembly can be made to fit the guide rail, ensuring the smooth and rapid opening and closing of the rolling shutter door, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A high-speed rolling shutter door with a reinforced guide structure includes a rolling cover, a rolling shutter door, and a guide mechanism. The rolling shutter door is wound around a reel inside the rolling cover, and an end plate is provided at the end of the rolling shutter door. A guide mechanism is provided at the bottom of the rolling cover. The guide mechanism includes a guide rail, a connecting rod, a mounting base, a rotating shaft A, a connecting arm, a pulley, a sleeve, a spring, and a movable rod. The bottom sides of the rolling cover are vertically arranged with guide rails, and the end plate is mounted with a mounting base located inside the guide rail via a connecting rod. The mounting base is movably connected to a connecting arm via a rotating shaft A, and a pulley that fits against the inner wall of the guide rail is installed at the end of the connecting arm. A sleeve is fixed at the middle position of the bottom of the mounting base, and springs are symmetrically installed at both ends inside the sleeve. The sleeve is movably connected to a movable rod via springs, and the end of the movable rod away from the sleeve is connected to the side of the connecting arm.
[0006] Furthermore, a horizontal through groove is provided at the middle of the top of the sleeve. A limiting rod extending to the outside of the through groove is welded to the top of one end of the movable rod inside the sleeve. Nuts are screwed to both ends of the outer periphery of the sleeve. The end of the movable rod is provided with a limiting rod extending to the outside of the sleeve. Nuts can be screwed into both ends of the sleeve. During debugging and maintenance, the nuts can be screwed along the outer periphery of the sleeve. After the nuts are screwed to the appropriate position, they are fixed, which can limit the movement range of the limiting rod, thereby limiting the extension range of the movable rod. This avoids the problem of excessive friction between the pulley and the inner wall of the guide rail due to excessive spring force, which affects the smoothness of opening and closing. During daily maintenance, the position of the nuts only needs to be adjusted according to the actual use of the guide rail and pulley.
[0007] Furthermore, a fixing rod is welded to the middle position of the bottom of the mounting base, and the mounting base is connected to the sleeve through the fixing rod; the fixing rod structure plays a connecting and fixing role between the bottom of the mounting base and the sleeve.
[0008] Furthermore, a fixing ring is welded to the center position inside the sleeve, and the spring is fixed to the surface of the fixing ring at one end inside the sleeve; the fixing ring is fixed at the center position inside the sleeve to fix the position of the spring.
[0009] Furthermore, a pivot B is installed at the end of the movable rod away from the sleeve, and the pivot B is connected to the connecting arm; the pivot B serves as a connection so that the movement of the movable rod can drive the angle of the connecting arm to be adjusted within a certain range.
[0010] Furthermore, both ends of the outer wall of the sleeve are provided with external threaded grooves and are connected to nuts through the external threaded grooves; the nuts can be screwed in and their positions adjusted through the external threaded grooves at both ends of the outer wall of the sleeve.
[0011] Compared with the prior art, this utility model has the following beneficial effects: The winding cover is connected to the roller shutter door through its internal reel. A transmission component is provided at the end of the winding cover, which controls the winding of the reel through its internal motor, thereby realizing the control and adjustment of the opening and closing of the roller shutter door. The end of the roller shutter door is provided with an end plate, and the two sides of the end plate are provided with mounting seats located inside the guide rail through connecting rods. The end of the connecting arm is provided with a pulley that fits against the inner wall of the guide rail, and the connecting arm can deflect around the pivot A. During the opening and closing of the roller shutter door, the end plate drives the mounting seats and pulleys to slide inside the guide rail. During the sliding process, the pulleys fit against the inner wall of the guide rail. At the same time, a spring and a movable rod are provided inside the sleeve and connected to the connecting arm. The spring maintains the elastic force towards the outside of the sleeve and then pushes to both sides through the movable rod. The connecting arm and pulleys ensure that the pulleys can fit against the inner wall of the guide rail, thus ensuring the cooperation between the pulleys and the guide rail during the opening and closing of the roller shutter door, reducing the shaking of the roller shutter door, and improving the smoothness and stability of the opening and closing process. The end of the movable rod is equipped with a limiting rod extending to the outside of the sleeve. Nuts can be screwed into both ends of the sleeve. During debugging and maintenance, the nuts can be screwed along the outer circumference of the sleeve. After the nuts are screwed into the appropriate position, they are fixed, which can limit the range of movement of the limiting rod, thereby limiting the extension of the movable rod. This avoids the problem of excessive friction between the pulley and the inner wall of the guide rail due to excessive spring force, which affects the smoothness of opening and closing. During daily maintenance, the position of the nuts can be adjusted only according to the actual use of the guide rail and pulley. Attached Figure Description

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0018] like Figure 1-4 As shown, a high-speed rolling shutter door with a reinforced guide structure includes a winding cover 1, a rolling shutter door 2, and a guide mechanism 3. The rolling shutter door 2 is wound around a reel inside the winding cover 1, and an end plate 201 is provided at the end of the rolling shutter door 2. The guide mechanism 3 is provided at the bottom of the winding cover 1. The guide mechanism 3 includes a guide rail 301, a connecting rod 302, a mounting base 303, a rotating shaft A304, a connecting arm 305, a pulley 306, a sleeve 308, a spring 310, and a movable rod 311. The bottom sides of the winding cover 1 are vertically provided with guide rails 301 and end plates... A mounting base 303 located inside the guide rail 301 is installed at the end of the 201 via a connecting rod 302. A connecting arm 305 is movably connected inside the mounting base 303 via a rotating shaft A304, and a pulley 306 that fits against the inner wall of the guide rail 301 is installed at the end of the connecting arm 305. A sleeve 308 is fixed at the middle position of the bottom of the mounting base 303, and springs 310 are symmetrically installed at both ends inside the sleeve 308. A movable rod 311 is movably connected to the sleeve 308 via the springs 310, and the end of the movable rod 311 away from the sleeve 308 is connected to the side of the connecting arm 305.
[0019] The sleeve 308 has a horizontally oriented through groove 4 at the top center. The movable rod 311 has a limiting rod 401 welded to the top of one end inside the sleeve 308, extending to the outside of the through groove 4. Nuts 403 are screwed to both ends of the outer periphery of the sleeve 308. The end of the movable rod 311 has a limiting rod 401 extending to the outside of the sleeve 308. Nuts 403 can be screwed into both ends of the sleeve 308. During debugging and maintenance, the nuts 403 can be screwed along the outer periphery of the sleeve 308. After the nuts 403 are screwed to the appropriate position, they are fixed, which can limit the movement range of the limiting rod 401, thereby limiting the extension range of the movable rod 311. This avoids the problem of excessive friction between the pulley 306 and the inner wall of the guide rail 301 due to excessive spring force of the spring 310, which affects the smoothness of opening and closing. During daily maintenance, the position of the nuts 403 can be adjusted according to the actual use of the guide rail 301 and the pulley 306.
[0020] The mounting base 303 has a fixing rod 307 welded to the middle of its bottom. The mounting base 303 is connected to the sleeve 308 via the fixing rod 307. A fixing ring 309 is welded to the center of the sleeve 308. One end of the spring 310 located inside the sleeve 308 is fixed to the surface of the fixing ring 309. The movable rod 311 has a rotating shaft B312 installed at its end away from the sleeve 308 and is connected to the connecting arm 305 via the rotating shaft B312. The fixing rod 307 serves to connect and fix the bottom of the mounting base 303 and the sleeve 308. The fixing ring 309 is fixed at the center of the sleeve 308 to fix the position of the spring 310. The rotating shaft B312 serves to connect the movable rod 311 so that the movement of the movable rod 311 can adjust the angle of the connecting arm 305 within a certain range.
[0021] The sleeve 308 has external threaded grooves 402 at both ends of its outer wall, which are connected to nuts 403. Nuts 403 can be screwed in and their positions adjusted through the external threaded grooves 402 at both ends of the outer wall of the sleeve 308.
[0022] It should be noted that this utility model is a high-speed rolling shutter door with a reinforced guide structure. In use, the winding cover 1 is connected to the rolling shutter door 2 through its internal reel. A transmission component is provided at the end of the winding cover 1, which controls the winding of the reel through its internal motor, thereby realizing the control and adjustment of the opening and closing of the rolling shutter door 2. The end of the rolling shutter door 2 is provided with an end plate 201, and the two sides of the end plate 201 are provided with mounting seats 303 located inside the guide rail 301 through connecting rods 302. The end of the connecting arm 305 is provided with... A pulley 306 is fitted against the inner wall of the guide rail 301, and the connecting arm 305 can deflect around the pivot A304. During the opening and closing of the roller shutter door 2, the end plate 201 drives the mounting base 303 and the pulley 306 to slide inside the guide rail 301. During the sliding process, the pulley 306 is fitted against the inner wall of the guide rail 301. At the same time, a spring 310 and a movable rod 311 are provided inside the sleeve 308 and connected to the connecting arm 305. The spring 310 maintains a spring force towards the outside of the sleeve 308 and thus through the movable arm 305... The lever 311 pushes the connecting arm 305 and pulley 306 to both sides to ensure that the pulley 306 can fit against the inner wall of the guide rail 301, thereby ensuring the cooperation between the pulley 306 and the guide rail 301 during the rolling and closing of the roller shutter 2, reducing the shaking of the roller shutter 2, and improving the smoothness and stability of the opening and closing process; the end of the movable lever 311 is provided with a limiting lever 401 extending to the outside of the sleeve 308, and nuts 403 can be screwed into both ends of the sleeve 308. During debugging and maintenance, the lever 401 can be adjusted along the sleeve. Tighten the nut 403 around the outer circumference of tube 308. Once the nut 403 is tightened to the appropriate position, it is fixed, which can limit the movement range of the limit rod 401, thereby limiting the extension range of the movable rod 311. This avoids the problem of excessive friction between the pulley 306 and the inner wall of the guide rail 301 due to excessive spring force of spring 310, which affects the smoothness of opening and closing. During daily maintenance, the position of nut 403 can be adjusted according to the actual use of guide rail 301 and pulley 306.
