[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0017] like Figures 1 to 13As shown, a mechanical fastener for the eaves of a light steel pitched roof TPO roll material includes a light steel purlin 1. A TPO roll material body 2 is attached to the upper surface of the light steel purlin 1. An installation hole 3 is provided inside the TPO roll material body 2. A positioning block 4 is attached to the inner wall of the installation hole 3. The bottom of the positioning block 4 is fixedly connected to the upper surface of the light steel purlin 1. A pressure strip 5 is fitted onto the surface of the positioning block 4. The bottom of the pressure strip 5 is attached to the upper surface of the TPO roll material body 2. A pressing ring 6 is fitted onto the surface of the positioning block 4. The bottom of the pressing ring 6 is attached to the upper surface of the pressure strip 5. A cross groove 7 is provided on the upper surface of the positioning block 4. A lifting ring is fixedly connected to the inner wall of the cross groove 7. The lifting support 8 has a first U-shaped plate 9 fixedly connected to its upper surface. A rectangular tube 10 is fitted onto the surface of the positioning block 4. The bottom of the rectangular tube 10 is in contact with the upper surface of the pressing ring 6. Rectangular holes 11 are provided on both the front and rear sides of the rectangular tube 10. Fixed square posts 12 are provided in contact with both the inner wall of the rectangular holes 11 and the inner wall of the first U-shaped plate 9. Second U-shaped plates 13 are fixedly connected to both the front and rear ends of the fixed square posts 12. The front and rear sides of the rectangular tube 10 are in contact with the inner wall of the second U-shaped plate 13. Second hollow blocks 14 are fixedly connected to both the front and rear sides of the second U-shaped plate 13. Springs 15 are fixedly connected to the inner wall of the second hollow blocks 14.
[0018] The lifting bracket 8 includes a first rectangular ring 81, a first hollow block 82, a threaded cylinder 83, a bolt 84, a rubber ring 85, and a second rectangular ring 86. The upper and lower sides of the first rectangular ring 81 are fixedly connected to the upper surface of the first hollow block 82 and the bottom of the first U-shaped plate 9, respectively. The left and right sides of the first rectangular ring 81 are in contact with the inner wall of the cross groove 7. The front and rear sides of the first hollow block 82 are in contact with the inner wall of the cross groove 7. The inner wall of the first hollow block 82 is fixedly connected to the surface of the threaded cylinder 83. The inner wall of the threaded cylinder 83 is threadedly connected to the surface of the bolt 84. The inner wall of the rubber ring 85 is sleeved on the surface of the bolt 84. The front and rear sides of the second rectangular ring 86 are fixedly connected to the inner wall of the cross groove 7. The left and right sides of the second rectangular ring 86 are in contact with the side of the first hollow block 82 and the side of the rubber ring 85, respectively. The inner wall of the second rectangular ring 86 is in contact with the surface of the bolt 84.
[0019] The major diameter of bolt 84 is equal to the width of the inner wall of the second rectangular ring 86, and the major diameter of bolt 84 is less than the height of the inner wall of the second rectangular ring 86.
[0020] It should be noted that when the inner wall of the mounting hole 3 is in contact with the surface of the positioning block 4, the TPO roll body 2 can be positioned by the cooperation of the positioning block 4 and the mounting hole 3. When the rectangular tube 10 is fixed on the positioning block 4, the TPO roll body 2 can be fixed on the light steel purlin 1 by the cooperation of the rectangular tube 10, the pressing ring 6, the pressure strip 5 and the positioning block 4. When the rectangular tube 10 is separated from the positioning block 4, the TPO roll body 2 can be directly separated from the light steel purlin 1.
[0021] Through the cooperation of bolt 84 and threaded cylinder 83, the user can clamp or release the second rectangular ring 86 by rotating bolt 84. When the rubber ring 85 and the first hollow block clamp the second rectangular ring 86, the friction between the rubber ring 85 and the second rectangular ring 86 prevents the position of the first rectangular ring 81 from changing. When the rubber ring 85 and the first hollow block release the second rectangular ring 86, the first rectangular ring 81 can slide up and down within the cross groove 7. At this time, the first rectangular ring 81 can move up and down within the cross groove 7. The cooperation of ring 81, first hollow block 82, threaded cylinder 83, bolt 84, rubber ring 85 and second rectangular ring 86 allows the distance between the first U-shaped plate 9 and the light steel purlin 1 to be adjusted according to the different thicknesses of the TPO roll body 2. This enables the mechanical fastener to fix the TPO roll body 2 of different thicknesses to the light steel purlin 1, thus making the mechanical fastener widely applicable. Through the cooperation of the first hollow block 82 and the cross groove 7, the first rectangular ring 81 can only move up and down within the cross groove 7.
[0022] By cooperating with the fixed square post 12 and the rectangular hole 11, the second U-shaped plate 13 can only move left and right. When the fixed square post 12 is inserted into the first U-shaped plate 9, the spring force of the spring 15 makes the fixed square post 12 and the first U-shaped plate 9 in close contact. Through the cooperation of the fixed square post 12 and the first U-shaped plate 9, the rectangular tube 10 is fixed on the positioning block 4. When the fixed square post 12 is separated from the first U-shaped plate 9, the rectangular tube 10 can be directly separated from the positioning block 4.
[0023] like Figures 1 to 14 As shown, the threaded cylinder 83 has a first positioning hole 16 inside, and the bolt 84 has a second positioning hole 17 inside. Positioning pins 18 are inserted into the inner walls of the first positioning hole 16 and the inner walls of the second positioning hole 17. A C-shaped spring piece 19 is fixedly connected to the top of the positioning pin 18. The inner wall of the C-shaped spring piece 19 is in contact with the surface of the threaded cylinder 83.
[0024] Among them, the elastic force of the C-shaped spring 19 is greater than the sum of the weights of the C-shaped spring 19 and the positioning post 18.
[0025] It should be noted that when the positioning pin 18 is inserted into the first positioning hole 16 and the second positioning hole 17, the bolt 84 cannot be rotated due to the cooperation of the positioning pin 18, the first positioning hole 16 and the second positioning hole 17. By locking the bolt 84, the rubber ring 85 and the second rectangular ring 86 will not loosen after the mechanical fastener is subjected to vibration. At the same time, when the positioning pin 18 is inserted into the first positioning hole 16 and the second positioning hole 17, the C-shaped spring 19 will be stuck on the threaded cylinder 83, and the positioning pin 18 cannot be moved out of the first positioning hole 16 and the second positioning hole 17 through the C-shaped spring 19.
[0026] like Figures 1 to 13 As shown, cylinders 20 are fixedly connected to both sides of the inner wall of the rectangular hole 11. A rubber sleeve 21 is bonded to the surface of the cylinder 20. A circular hole 22 is opened inside the fixed square column 12. The inner wall of the circular hole 22 is in contact with the surface of the rubber sleeve 21.
[0027] It should be noted that the friction between the rubber sleeve 21 and the fixed square column 12 makes it difficult for the fixed square column 12 to jump left and right after the mechanical fastener is subjected to vibration.
[0028] The working principle of this utility model is as follows: First, fix the positioning block 4 on the light steel purlin 1 and open the mounting hole 3 in the TPO roll body 2. Then, lay the TPO roll body 2 flat on the light steel purlin 1 and make the inner wall of the mounting hole 3 fit with the surface of the positioning block 4. At this time, the TPO roll body 2 can be positioned by the cooperation of the positioning block 4 and the mounting hole 3.
[0029] Then, the pressure strip 5, the pressing ring 6, and the rectangular tube 10 are sequentially placed on the positioning block 4. By pinching the two second U-shaped plates 13 on the left and right, the distance between the two fixed square posts 12 on the left and right is made smaller than the distance between the two first U-shaped plates 9 on the left and right. When the fixed square posts 12 are aligned with the first U-shaped plates 9, the second U-shaped plates 13 are released. Through the elastic force of the spring 15, the fixed square posts 12 are automatically inserted into the first U-shaped plates 9. At this time, through the cooperation of the fixed square posts 12 and the first U-shaped plates 9, the rectangular tube 10 is fixed on the positioning block 4. Through the cooperation of the rectangular tube 10, the pressing ring 6, the pressure strip 5, and the positioning block 4, the TPO roll body 2 can be fixed on the light steel purlin 1.
[0030] When it is necessary to separate the TPO roll body 2 from the light steel purlin 1, by pinching the two second U-shaped plates 13 on the left and right, the fixed square post 12 is moved out from the first U-shaped plate 9. After the fixed square post 12 is moved out from the first U-shaped plate 9, the rectangular tube 10 is removed from the positioning block 4. After the rectangular tube 10 is removed from the positioning block 4, the TPO roll body 2 can be directly separated from the light steel purlin 1.
[0031] When it is necessary to adjust the distance between the first U-shaped plate 9 and the light steel purlin 1, first remove the positioning pin 18 from the first positioning hole 16 and the second positioning hole 17. Then, by rotating the bolt 84, the rubber ring 85 and the first hollow block are loosened from the second rectangular ring 86. Then, the first rectangular ring 81 is moved to a suitable position, and by rotating the bolt 84, the rubber ring 85 and the first hollow block clamp the second rectangular ring 86. At this time, the friction between the rubber ring 85 and the second rectangular ring 86 prevents the position of the first rectangular ring 81 from changing. When the position of the first rectangular ring 81 is fixed... Then, the positioning pin 18 is inserted into the first positioning hole 16 and the second positioning hole 17. Through the cooperation of the positioning pin 18, the first positioning hole 16 and the second positioning hole 17, the bolt 84 cannot be rotated. By locking the bolt 84, the rubber ring 85 and the second rectangular ring 86 will not loosen after the mechanical fastener is subjected to vibration. At the same time, when the positioning pin 18 is inserted into the first positioning hole 16 and the second positioning hole 17, the C-shaped spring piece 19 will be stuck on the threaded cylinder 83, and the positioning pin 18 cannot be moved out of the first positioning hole 16 and the second positioning hole 17 through the C-shaped spring piece 19.
[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
