Description

Technical Field

[0001] This utility model relates to the field of carport structure technology, specifically a carport roof tensioning structure. Background Technology

[0002] A carport is a building structure or facility used to park and protect vehicles. It can shield vehicles from the erosion of natural factors such as sunlight, rain, wind, and snow, reduce aging, fading, and damage to the vehicle's surface, and extend the vehicle's service life.

[0003] However, in some existing carports, the canopy is separate from the structure, requiring the canopy to be manually covered and secured. Under prolonged exposure to external forces such as rain, snow, and storms, the canopy gradually loosens and becomes less taut, affecting the protective effect of the carport roof and potentially causing safety issues.

[0004] In order to maintain the tautness of the carport roof and avoid reducing its protective properties, this application proposes a carport roof tensioning structure. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a tensioning structure for the top of a carport, which provides traction for the canopy covering the upper part of the side support frame, thereby keeping the canopy in a tensioned state on the upper side of the side support frame.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tensioning structure for the top of a carport, comprising a connecting rod, with side supports fixedly connected to both ends of the connecting rod. A winding box is fixedly connected to the left end of the side supports, located above the connecting rod. Fabric rollers are rotatably connected to the inner walls of both ends of the winding box. Two rotating wheels are fixedly connected to both ends of the fabric rollers. A placement frame is fixedly connected to the middle of the left end of the connecting rod. A dual-axis motor is fixedly connected to the inner wall of the bottom end of the placement frame. Drive rods are fixedly connected to the drive ends of the dual-axis motor. The outer walls of the drive rods on opposite sides are... The drive rod is rotatably connected to the lower side of the inner wall of the side support frame. The inner wall of the side support frame is provided with through grooves on the outer side of the drive rod. The opposite end of the drive rod is fixedly connected to a first rotating wheel. The bottom of the outer diameter of the first rotating wheel is engaged with a synchronous belt. The other end of the inner diameter of the synchronous belt is engaged with the top of the outer diameter of the second rotating wheel. The top of the take-up box is fixedly connected to the middle of the front and rear sides of the top. The lower end of the gap frame is away from the upper end of the side support frame. The inner wall of the opposite end of the gap frame is provided with a canopy. One end of the canopy is fixedly connected to the top of the fabric roller. The inner walls of the front and rear sides of the other end of the canopy are provided with wire holes.

[0007] Further description: Each of the upper middle inner walls of the side support frame is equipped with pulleys. Guide rails are fixedly connected to both the front and rear sides of the upper end of the side support frame. Adapter rods are fixedly connected to both ends of the pulleys. The outer walls of the adapter rods are slidably connected to the inner walls of the guide rails. A return frame is rotatably connected to the outer walls of two adjacent adapter rods. A traction rope is fixedly connected to the right end of each return frame. The other end of the traction rope is fixedly connected to the outer wall of the drive rod located inside the through groove. Here, a track groove is opened in the middle of the upper end of the side support frame, and the pulleys are placed in the track groove. When the traction rope pulls the return frame, it will cause the pulleys to roll in the track groove under the connection of the adapter rods.

[0008] Further description: Each of the following is a description of the structure: a storage block is fixedly connected to the left end of each of the storage blocks; a folding plate is fixedly connected to the right side of the top of each storage block; a sliding bolt is slidably connected to the inner wall of the top left of each storage block; and the outer wall of each sliding bolt passes through the inner wall of the wire hole. Here, when the wire hole is located outside the sliding bolt, the folding plate and the sliding bolt form an enclosure, making it difficult for the wire hole to detach from the enclosure.

[0009] Further description: Each of the sliding bolts has a base plate fixedly connected to its bottom end, and each of the base plates has a spring fixedly connected to its top end on the outside of the sliding bolt. The top end of each spring is fixedly connected to the inner wall of the storage block. Here, when the spring is stretched, it will generate a certain elastic potential energy.

[0010] Further description: Each side support frame has a grooved frame fixedly connected to one end of its lower middle section. The inner wall of the bottom end of each grooved frame is threaded with a screw rod that passes through both the inner and outer sides of the grooved frame. The bottom end of each screw rod is rotatably connected to a connecting plate. The bottom end of each connecting plate is fixedly connected to a hook. The inner wall of the hook passes through the outer wall of the traction rope. Here, the inner wall of the bottom end of the grooved frame has a threaded surface that fits with the threaded outer wall of the screw rod and provides a trajectory for the movement of the screw rod.

[0011] Further description: Each groove frame has a fixed retaining block at its bottom left end, and each connecting plate has a fixed sliding rod at its top left side. The outer wall of each sliding rod is slidably connected to the inner wall of the retaining block. Here, the sliding rod slides within the retaining block, providing a path for the connecting plate to move.

[0012] Further description: The top left side of the winding box is fixedly connected to two shelves, front and back. A snap-fit ​​plate is provided on the upper side of the opposite end of the shelf. The shape of the front and back ends of the snap-fit ​​plate matches the shape of the upper inner wall of the opposite end of the shelf.

[0028] 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.

[0029] Example 1

[0030] Please see Figures 1-5 A tensioning structure for a carport roof includes a connecting rod 10. Side supports 1 are fixedly connected to both ends of the connecting rod 10. A winding box 2 is fixedly connected to the left end of the side supports 1, located above the connecting rod 10. Fabric rollers 34 are rotatably connected to the inner walls of both ends of the winding box 2. Two rotating wheels 7 are fixedly connected to both ends of the fabric rollers 34. A placement frame 3 is fixedly connected to the middle of the left end of the connecting rod 10. A dual-axis motor 4 is fixedly connected to the inner wall of the bottom end of the placement frame 3. Drive rods 5 are fixedly connected to the drive ends of the dual-axis motor 4. The opposite sides of the outer walls of the drive rods 5 are rotatably connected to the lower inner wall of the side supports 1. The inner wall of the side support frame 1 is provided with through grooves 17 on the outside of the drive rod 5. The opposite end of the drive rod 5 is fixedly connected to a first wheel 6. The bottom of the outer diameter of the first wheel 6 is engaged with a synchronous belt 8. The other end of the inner diameter of the synchronous belt 8 is engaged with the top of the outer diameter of the second wheel 7. The top of the take-up box 2 is fixedly connected to the middle of the front and rear sides of the top. The lower end of the gap frame 16 is away from the upper end of the side support frame 1. The inner wall of the opposite end of the gap frame 16 is provided with a canopy 13. One end of the canopy 13 is fixedly connected to the top of the fabric roller 34. The inner walls of the front and rear sides of the other end of the canopy 13 are provided with wire holes 18.

[0031] The upper middle inner wall of the side support frame 1 is equipped with pulleys 19. The front and rear sides of the upper end of the side support frame 1 are fixedly connected to guide rails 9. The front and rear ends of the pulleys 19 are fixedly connected to the adapter rods 20. The outer walls of the adapter rods 20 are slidably connected to the inner walls of the guide rails 9. The outer walls of two adjacent adapter rods 20 are rotatably connected to a return frame 15. The right end of the return frame 15 is fixedly connected to a traction rope 14. The other end of the traction rope 14 is fixedly connected to the outer wall of the drive rod 5 located inside the through groove 17. The left end of the return frame 15 is fixedly connected to a storage block 21. The top right side of the storage block 21 is fixedly connected to a folding plate 22. The left inner wall of the top of the storage block 21 is slidably connected to a sliding bolt 23. The outer wall of the sliding bolt 23 is through the inner wall of the line hole 18. The bottom end of the sliding bolt 23 is fixedly connected to a base plate 25. The top of the base plate 25 located outside the sliding bolt 23 is fixedly connected to a spring 24. The top of the spring 24 is fixedly connected to the inner wall of the storage block 21.

[0032] To further explain, firstly, bolts can be passed through the mounting holes of the side support frame 1 base and inserted into pre-drilled holes in the ground for fixation. By pulling down the base plate 25, the sliding bolt 23 will slide accordingly, simultaneously stretching the spring 24. Next, the inner side of the wire hole 18 is fitted over the outer side of the sliding bolt 23. Then, the base plate 25 is released, and under the elastic action of the spring 24, the sliding bolt 23 will slide back to its original position and insert into the wire hole 18, thus firmly securing the wire hole 18 at that location, completing the fixation of both ends of the tarpaulin 13. Subsequently, the dual-axis motor 4 is started, and its two drive ends will drive the drive rod 5 to rotate clockwise. When the drive rod 5 starts to wind up the traction rope 14, the drive rod 5 drives the first rotating wheel 6 to rotate. Through the transmission connection of the synchronous belt 8, the second rotating wheel 7 drives the fabric roller 34 to rotate, and begins to unwind the canopy 13 fixed on its outer wall. The traction rope 14, with the help of the storage block 21 and the return frame 15, drives the two ends of the canopy 13 to move on the upper side of the side support frame 1. During this process, the pulley 19 will roll in the track groove at the upper end of the side support frame 1, and the two end connecting rods 20 will slide in the inner wall of the guide rail frame 9 until the canopy 13 completely covers the upper side of the side support frame 1. At this time, the dual-axis motor 4 stops running.

[0033] Example 2

[0034] Please see Figures 6-10Furthermore, based on Embodiment 1, a grooved frame 11 is fixedly connected to one end of the lower middle section of each side support frame 1. A screw 12 is threadedly connected to the inner wall of the bottom end of each grooved frame 11, penetrating both the inner and outer sides of the grooved frame 11. A connecting plate 28 is rotatably connected to the bottom end of each screw 12. A hook 29 is fixedly connected to the bottom end of each connecting plate 28. The inner wall of the hook 29 passes through the outer wall of the traction rope 14. A retaining block 26 is fixedly connected to the bottom left end of each grooved frame 11, and a sliding rod 27 is fixedly connected to the left side of the top end of each connecting plate 28. The outer wall of the slide bar 27 is slidably connected to the inner wall of the fixing block 26. The top left side of the take-up box 2 is fixedly connected to the front and rear parts of the shelf 30. The upper side of the opposite end of the shelf 30 is provided with a snap plate 32. The shape of the front and rear ends of the snap plate 32 matches the shape of the upper inner wall of the opposite end of the shelf 30. The right end of the snap plate 32 is fixedly connected to the brush plate 33. The lower side of the opposite end of the shelf 30 is fixedly connected to the inclined frame 31. The right ends of the inclined frame 31 and the brush plate 33 are both in contact with the outer wall of the canopy 13.

[0035] To further explain, the next step is to tension the tarpaulin 13. Place the outer side of the traction rope 14 inside the hook 29. After the preparation is complete, turn the knob on the top of the screw 12. The screw 12 will move upward along the thread in the inner wall of the groove frame 11. The bottom of the screw 12, along with the slide bar 27 on one side of the top of the connecting plate 28, slides upward in the fixing block 26, so that the hook 29 pulls up the part that contacts the traction rope 14, pulling the traction rope 14 to a certain height and putting it in a taut state, thereby ensuring that the tarpaulin 13 can be tensioned.

[0036] When it is necessary to clean the upper surface of the cover 13, start the dual-axis motor 4 to reverse, drive the rod 5 to rotate counterclockwise, and under the transmission of the synchronous belt 8, the rotating wheel 7 rotates synchronously, driving the cloth roller 34 to rotate and roll up the cover 13. Install the brush plate 33 on one side of the surface of the cover 13 and stick it. During the rolling process, the brush plate 33 rubs against the surface of the cover 13 to clean one side of the surface of the cover 13. The dust and impurities swept down will slide down the inclined frame 31. After cleaning is completed, remove the two ends of the snap plate 32 from the upper inner wall between the shelves 30 to facilitate cleaning and maintenance of the brush plate 33.

[0037] Working principle: First, place the thread holes 18 on the surface of the tarpaulin 13 into the sliding bolts 23. First, pull down the base plate 25 to make it slide the sliding bolts 23 and stretch the spring 24. Then, place the inner side of the thread hole 18 around the sliding bolt 23. Then, release the base plate 25. Under the elastic action of the spring 24, the sliding bolt 23 will slide back to its original position and insert into the thread hole 18, thus fixing the thread hole 18 at this point and fixing both ends of the tarpaulin 13. Next, place the outer side of the traction rope 14 inside the hook 29. Then, start the dual-axis motor 4, so that its two drive ends drive the drive rods 5. Rotate clockwise to wind up the traction rope 14. At the same time, drive rod 5 drives wheel 6 to rotate. Under the transmission connection of synchronous belt 8, wheel 7 drives fabric roller 34 to rotate and unwind the fabric 13 fixed on its outer wall. The traction rope 14, connected by storage block 21 and return frame 15, drives the two ends of fabric 13 to move on the side support frame 1. At the same time, pulley 19 rolls in the track groove at the upper end of the side support frame 1, and the two end adapter rods 20 slide in the inner wall of guide rail frame 9 until the fabric 13 completely covers the upper side of the side support frame 1. Then the dual shaft motor 4 stops running.

[0038] Next, by rotating the knob at the top of the screw 12, the screw 12 moves upward along the thread in the inner wall of the groove frame 11. At the same time, the bottom of the screw 12, along with the slide bar 27 on one side of the top of the connecting plate 28, slides upward in the fixing block 26. As a result, the hook 29 is pulled upward to the part that contacts the traction rope 14 and is kept at a certain height, so that the traction rope 14 is in a relatively taut state and is not easy to loosen, so that the canopy 13 can be kept in a taut state.

[0039] Then, when cleaning the upper surface of the cover 13, the dual-axis motor 4 can be started in reverse to drive the drive rod 5 to rotate counterclockwise. At the same time, under the transmission connection of the synchronous belt 8, the rotating wheel 7 rotates synchronously, which drives the cloth roller 34 to rotate and roll up the cover 13. The brush plate 33 is installed on one side of the surface of the cover 13 and is attached to it. While rolling up the cover 13, the brush plate 33 rubs against its surface and cleans one side of the surface of the cover 13. The dust and impurities cleaned will slide down the inclined frame 31. Then, the two ends of the snap plate 32 are removed from the upper inner wall between the shelves 30, which makes it easier to clean and maintain the brush plate 33.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
