Description
Technical Field
[0001] The utility model relates to the technical field of garage doors, in particular to a pre-pressure wind-resistant garage door. Background Art
[0002] Since the structure of a rolling door is made up of multiple curtain sheets and the shafts connecting the curtain sheets, and the curtain sheets can rotate relative to each other around the shafts, it is suitable as a garage door. Usually, a winding mechanism and a storage bag for accommodating the rolling door in the winding state are arranged at the top of the door frame. Both sides of the door frame are the tracks of the rolling door, and the tracks are usually C-shaped tracks. Multiple rollers connecting the shafts are arranged on both sides of the rolling door. When lifting and lowering the garage door, the rollers roll in the tracks to reduce the friction force.
[0003] Generally, the width of the track is slightly larger than the diameter of the roller, so that the roller can rotate freely in the track. However, this gap also brings instability to the roller in the track. Especially after the garage door is locked, when there is a pressure difference between the inside and outside of the garage, because the roller has a margin of movement in the track, the garage door will shake, which will have an adverse impact on the connection between the roller and the curtain sheet. Content of the Utility Model
[0004] In view of the technical problems existing in the garage door in the prior art, the first aspect of the utility model provides a pre-pressure wind-resistant garage door, including:
[0005] Tracks;
[0006] A rolling door arranged in the tracks, the rolling door includes multiple curtain sheets movably connected to each other through connecting shafts, and the ends of the connecting shafts are connected with rollers;
[0007] A winding component arranged above the tracks, for winding and unwinding the rolling door to make the rollers roll in the tracks;
[0008] A pressing component connected to the tracks, for pressing the rollers in the tracks so that the rollers cannot rotate relative to the tracks.
[0009] Wherein, the tracks include a C-shaped track structure. A pressing plate is arranged on the first side of the C-shaped track structure, and a gasket is arranged on the second side. The rollers are located between the pressing plate and the gasket. The pressing component is connected to the pressing plate to control the pressing plate to approach or move away from the gasket. When the pressing plate approaches the gasket, the outer walls of the rollers are simultaneously in contact with the pressing plate and the gasket, so that the rollers are fixed in the C-shaped track structure.
[0010] Preferably, the pressing plate is configured to have a U-shaped cross-section, wherein the opening of the pressing plate faces the side of the pressing component.
[0011] Preferably, the two side walls of the pressing plate are attached to the inner walls of the C-shaped track structure.
[0012] Preferably, the gasket is fixedly connected to the inner wall of the C-shaped track structure. The width of the gasket is the same as that of the pressing plate, and the thickness of the gasket is greater than 5 mm.
[0013] Preferably, the pressing member includes a pair of support plates, a connecting shaft, a pressing tongue and a pressing rod. A window is formed on the pressing plate, and the window is inside the pair of support plates. The connecting shaft is connected between the pair of support plates. Both the pressing tongue and the pressing rod are fixed to the outer wall of the connecting shaft, and the pressing tongue extends into the window.
[0014] Preferably, the pressing tongue can be controlled by the pressing rod to rotate to a first position or a second position. When the pressing tongue is in the first position, the pressing tongue is separated from the pressing plate. When the pressing tongue is in the second position, the pressing tongue presses against the surface of the pressing plate and presses the pressing plate against the roller.
[0015] Preferably, the angle between the pressing tongue and the pressing rod is greater than 90 degrees.
[0016] Preferably, when the pressing tongue is in the second position, the pressing rod is parallel to the pressing plate, and the end surface of the pressing tongue in contact with the pressing plate is an arc surface.
[0017] Preferably, one or more pressing members are arranged along the length direction of the track.
[0018] Preferably, the distance between two adjacent pressing members is greater than 50 cm.
[0019] Compared with the prior art, the advantages of the present utility model are as follows:
[0020] In the present utility model, a pressing plate and a gasket are arranged on the inner wall of the original C-shaped track. The distance between the pressing plate and the gasket can be controlled by the pressing member. When the user opens and closes the garage door, the distance between the pressing plate and the gasket is slightly greater than the diameter of the roller, and the roller can roll freely to keep the track smooth. When the garage door is closed, the distance between the pressing plate and the gasket can be controlled to be slightly less than the diameter of the roller, so that the roller is positioned in the track. Therefore, under the action of air flow, the garage door will not shake greatly, ensuring the reliability of each connection structure. Description of the Drawings

[0023] Figure 2 It is a schematic structural diagram of the track shown in the present utility model;
[0024] Figure 3 It is a schematic structural diagram of the pressing component shown in the present utility model;
[0025] Figure 4 It is a schematic diagram of the tongue being in the second position shown in the present utility model. Detailed implementation manners
[0026] In order to better understand the technical content of the present utility model, specific embodiments are hereby given and described in conjunction with the accompanying drawings as follows.
[0027] As Figure 1 shown, a first aspect of the present utility model provides a pre - pressed wind - resistant garage door, which includes a track 1, a rolling shutter door 2, a winding component 3 and a pressing component 4. The track 1 is arranged on both sides of the door frame. The rolling shutter door 2 is arranged in the track 1. The rolling shutter door 2 includes a plurality of curtain sheets that are movably connected to each other through a connecting shaft. The end of the connecting shaft is connected to a roller 21. The winding component 3 is arranged above the track 1 and is used for winding and unwinding the rolling shutter door 2 to make the roller 21 roll in the track 1.
[0028] In this way, when the winding component 3 winds or unwinds the rolling shutter door 2, the end of the rolling shutter door 2 can rise or fall along the direction of the track 1 to open or close the rolling shutter door 2.
[0029] Furthermore, the pressing component 4 is connected to the track 1 and is used for pressing the roller 21 tightly in the track 1 so that the roller 21 cannot rotate relative to the track 1.
[0030] In this way, after the rolling shutter door 2 is closed, the roller 21 in the rolling shutter door is pressed tightly in the track 1 by the pressing component 4, so that there is no margin for the roller 21 to move. Therefore, when there is a pressure difference inside and outside the rolling shutter door 2, since the roller 21 is in a fixed position and will not shake with the change of the external air flow, the relative position between the roller 21 and the curtain sheet of the rolling shutter door is relatively stable and not easy to loosen.
[0031] As Figure 2 shown, the track 1 includes a C - shaped track structure 11. A pressing plate 12 is arranged on the first side of the C - shaped track structure 11, and a gasket 13 is arranged on the second side. The roller 21 is located between the pressing plate 12 and the gasket 13.
[0032] In this way, a space for the roller 21 to move is formed between the pressing plate 12 and the gasket 13. When the roller 21 contacts the surface of either the gasket 13 or the pressing plate 12, it can roll freely. However, when both the pressing plate 12 and the gasket 13 are in contact with the surface of the roller 21, the roller 21 cannot rotate. Especially when the distance between the pressing plate 12 and the gasket 13 is slightly smaller than the diameter of the roller 21, there is a large frictional force between the roller 21 and the gasket 13, and the roller 21 is in a relatively fixed position state.
[0033] Furthermore, the pressing member 4 is connected to the pressing plate 12 to control the pressing plate 12 to approach or move away from the gasket 13. When the pressing plate 12 approaches the gasket 13, the outer wall of the roller 21 is simultaneously in contact with the pressing plate 12 and the gasket 13, fixing the roller 21 in the C-shaped track structure 11.
[0034] In this way, the position of the pressing plate 12 can be controlled by the pressing member 4. After the garage door is closed, the pressing member 4 is controlled to move the pressing plate 12 closer to the gasket 13 to press the roller 21. This method of fixing the roller 21 is simple and effective, and it is easy to modify the existing C-shaped track structure 11.
[0035] In an alternative embodiment, the pressing plate 12 is configured to have a U-shaped cross-section, where the opening of the pressing plate 12 faces the side of the pressing member 4. In this way, the rigidity of the pressing plate 12 can be improved. Especially in the length direction, when the pressing plate 12 is squeezed at a certain point, the pressing plate 12 can move as a whole in the direction of the pressure.
[0036] Furthermore, the two side walls of the pressing plate 12 are in fit with the inner wall of the C-shaped track structure 11. In this way, the position of the pressing plate 12 can be ensured to be stable to avoid the pressing plate 12 from shaking.
[0037] In an alternative embodiment, the gasket 13 is fixedly connected to the inner wall of the C-shaped track structure 11. The width of the gasket 13 is the same as the width of the pressing plate 12, and the thickness of the gasket 13 is greater than 5 mm. The gasket 13 is preferably made of a rubber gasket, which has good elasticity and wear resistance and can generate a greater resistance to the roller 21 in a squeezed state.
[0038] As Figure 3 and Figure 4 shown, the pressing member 4 includes a pair of support plates 41, a connecting shaft 42, a pressing tongue 43, and a pressing rod 44. A window 401 is opened on the pressing plate 12. The window 401 is inside the pair of support plates 41. The connecting shaft 42 is connected between the pair of support plates 41. Both the pressing tongue 43 and the pressing rod 44 are fixed to the outer wall of the connecting shaft 42, and the pressing tongue 43 extends into the window 401.
[0039] In this way, the pressure bar 44, the tongue depressor 43 and the connecting shaft 42 form a lever. The pressure bar 44 is the operating end, and the tongue depressor 43 is the driving end. The tongue depressor 43 generates pressure on the pressing plate 12 by contacting the surface of the pressing plate 12. When the pressure bar 44 is pressed downward, the tongue depressor 43 rotates inward toward the window 401, pushing the pressing plate 12 in the direction of the gasket 13 and squeezing the roller 21.
[0040] Optionally, the tongue depressor 43 can be controlled by the pressure bar 44 to rotate to the first position or the second position. When the tongue depressor 43 is in the first position, the tongue depressor 43 is separated from the pressing plate 12. It can be understood that when the tongue depressor 43 is in the first position, it does not exert a squeezing effect on the pressing plate 12, and it is not determined as a certain angle, but can also refer to a range value. For example, when the pressure bar 44 forms an angle of 40° to 60° with the ground, the tongue depressor 43 is in the first position. When the tongue depressor 43 is in the second position, the tongue depressor 43 presses against the surface of the pressing plate 12 and presses the pressing plate 12 against the roller 21. It can be understood that when the tongue depressor 43 is in the second position, it exerts a squeezing effect on the pressing plate 12, especially making the distance between the pressing plate 12 and the gasket 13 smaller than the diameter of the roller 21. At this time, the tongue depressor 43 is at an angle close to perpendicular to the pressing plate 12.
[0041] As Figure 4 shown, the angle between the tongue depressor 43 and the pressure bar 44 is greater than 90 degrees. When the tongue depressor 43 is in the second position, the pressure bar 44 is parallel to the pressing plate 12, and the end face of the tongue depressor 43 in contact with the pressing plate 12 is an arc surface.
[0042] In this way, the arc surface part of the tongue depressor 43 close to the pressure bar 44 contacts the pressing plate 12. Once the pressing plate 12 exerts a reaction force on the tongue depressor 43, the pressure bar 44 continues to rotate downward until it fits against the outer surface of the C-shaped track structure 11, forming a relatively stable state so that the tongue depressor 43 will not move from the second position to the first position due to external force.
[0043] In the above embodiment, one or more pressing components 4 are arranged along the length direction of the track 1. The distance between two adjacent pressing components 4 is greater than 50 cm. In this way, a good positioning effect can be achieved on the roller 21.
[0044] In the above embodiment, the pressure bar 44 can be manually controlled by the user or automatically controlled through an electric drive structure.
[0045] In combination with the above embodiments, the utility model arranges a pressure plate and a gasket on the inner wall of the original C-shaped track. The pressure plate can control the distance between the pressure plate and the gasket through a clamping component. When the user is opening and closing the garage door, the distance between the pressure plate and the gasket is kept slightly larger than the diameter of the roller. The roller can roll freely to keep the track smooth. When closing the garage door, the distance between the pressure plate and the gasket can be controlled to be slightly smaller than the diameter of the roller so that the roller is positioned in the track. Therefore, under the action of airflow, the garage door will not shake greatly to ensure the reliability of each connecting structure.
[0046] Although the present invention has been disclosed as above with preferred embodiments, it is not intended to limit the present invention. A person with ordinary knowledge in the technical field to which the present invention belongs may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be determined by the definition of the claims.
