Description
Technical Field
[0001] This utility model belongs to the field of vehicle canopy installation technology, and relates to a clamping mechanism for canopy tensioning. Background Technology
[0002] The canopy material of membrane structure vehicle canopies is membrane structure, and the biggest characteristics of membrane material are high strength, good durability, fire resistance, good self-cleaning properties, unaffected by ultraviolet rays, and long service life, generally 15-30 years. It has high light transmittance, with a light transmittance of 13%, and a heat reflectivity of 73%, with very little heat absorption.
[0003] Currently, the installation process for carports involves first installing the carport frame on the ground, then securing the tarpaulin to the top of the frame. When securing the tarpaulin, one side of the tarpaulin is first fixed to one side of the frame; simultaneously, a rope is wrapped around the other side of the tarpaulin. When pulling the rope-wrapped side, a tool is used to clamp the rope-wrapped tarpaulin (the rope prevents the tarpaulin from detaching from the tool). The tool has a C-shaped connector; when pulling the tarpaulin, a rope is connected to this connector, and then the rope is pulled outwards (usually using a manual tensioner). The rope, through the connector and tool, pulls the tarpaulin outwards, causing it to stretch and lie flat on the frame. Finally, the tarpaulin is secured to the frame, and any excess tarpaulin is trimmed. However, current methods typically only allow pulling the tarpaulin towards its free end. Therefore, if the pulling effect is poor, adjustments to the tool angle or the tensioner position are necessary, resulting in less than ideal performance. Utility Model Content
[0004] The purpose of this invention is to provide a tarpaulin tensioning clamping mechanism to solve the problem of poor operation.
[0005] To solve the above-mentioned technical problems, this utility model provides a tarpaulin tensioning clamping mechanism, including a rectangular fixed plate and a movable plate. Two clamping screws are vertically arranged on the top of the fixed plate. The clamping screws move through the movable plate. A clamping nut is threaded onto the clamping screw. The clamping nut is used to drive the movable plate closer to the fixed plate. A first connecting member is provided on one side of the fixed plate, and a second connecting member is provided at both ends. Both the first connecting member and the second connecting member are used to connect to the outside.
[0006] The present invention is further configured such that both the first connector and the second connector are C-shaped, and both ends of the first connector and the second connector are connected to the fixing plate.
[0007] The present invention is further configured such that an anti-slip strip is fixedly provided on the side of the movable plate away from the first connecting member, and the anti-slip strip is located between the fixed plate and the movable plate.
[0008] The present invention is further configured such that a support strip parallel to the anti-slip strip is fixedly provided on the side of the fixed plate near the first connecting member, the support strip is located between the fixed plate and the movable plate, and the clamping screw is located between the anti-slip strip and the support strip.
[0009] The present invention is further configured such that the fixed plate has two clearance holes, the movable plate has two rotating seats on the side near the fixed plate, the support bar moves through the rotating seats, and the rotating seats are hinged to the support bar, with the free end of the rotating seats movably located in the clearance holes.
[0010] The present invention is further configured such that a protruding seat is provided on the top of the movable plate, the clamping screw moves through the middle of the protruding seat, the top of the protruding seat is provided with an arc-shaped rotating groove, a fitting part is movably sleeved on the clamping screw, the bottom of the fitting part moves against the inner wall of the rotating groove, and the top abuts against the clamping nut.
[0011] The present invention is further configured such that a separation column is provided at the bottom of the movable plate, and the separation column moves through the fixed plate.
[0012] The present invention is further provided with an operating plate at the bottom of the separation column having a cross-section larger than that of the separation column.
[0013] Compared with existing technologies, this utility model provides a clamping mechanism for tarpaulin tensioning. During on-site installation of the tarpaulin, the end of the tarpaulin without ropes is first fixedly connected to one side of the frame. Then, the part of the tarpaulin with ropes is placed between the fixed plate and the movable plate. The clamping nut is then rotated, driving the movable plate closer to the fixed plate until the movable plate and the fixed plate clamp the tarpaulin with ropes. A tensioner (a commercially available product, not the subject of this application) is then used to connect a first connector and one or two second connectors. During subsequent tarpaulin traction, the first connector primarily provides the traction. If the tarpaulin tilts or becomes misaligned during traction, the tensioners on one or both second connectors provide traction, thus allowing adjustment of the tarpaulin's angle and orientation without moving the tensioners. In practical use, the tensioner has one end used to pull the tarpaulin, while the other end is connected to a fixed tree or rock. Therefore, when the tension angle of the tensioner is not good, it is necessary to separate the outside of the tensioner from the tree or rock and then find a suitable tree or rock, which is quite cumbersome in practice. In contrast, this application uses multi-angle traction on the fixing plate, requiring only one fixing. Moreover, even if the direction or angle of the tarpaulin is not good after fixing, there is no need to adjust the position of the tensioner.
[0014] In another embodiment, the first connector is pulled using a tensioner, while the second connector is pulled manually after being connected to a rope. This can also tension the tarpaulin during installation; however, this method is mainly suitable for cases where the tarpaulin is small. Attached Figure Description

[0023] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a more detailed explanation of the tarpaulin tensioning clamping mechanism proposed in this utility model. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model. The same or similar reference numerals in the drawings represent the same or similar parts.
[0024] Example 1
[0025] A tarpaulin tensioning clamping mechanism, such as Figures 1 to 3As shown, it includes a rectangular fixed plate 1 and a movable plate 2. Two clamping screws 3 are vertically arranged on the top of the fixed plate 1. The clamping screws 3 move through the movable plate 2. A clamping nut 4 is threaded onto the clamping screw 3. The clamping nut 4 is used to drive the movable plate 2 closer to the fixed plate 1. A first connecting member 5 is provided on one side of the fixed plate 1, and a second connecting member 6 is provided at both ends. Both the first connecting member 5 and the second connecting member 6 are used to connect to the outside.
[0026] Both the first connector 5 and the second connector 6 are C-shaped, and both ends of the first connector 5 and the second connector 6 are connected to the fixing plate 1. This improves the structural strength of the first connector 5 and the second connector 6.
[0027] An anti-slip strip 7 is fixedly installed on the side of the movable plate 2 away from the first connecting member 5, and the anti-slip strip 7 is located between the fixed plate 1 and the movable plate 2. A support strip 8 parallel to the anti-slip strip 7 is fixedly installed on the side of the fixed plate 1 close to the first connecting member 5, and the support strip 8 is located between the fixed plate 1 and the movable plate 2, and the clamping screw 3 is located between the anti-slip strip 7 and the support strip 8.
[0028] A separation column 13 is provided at the bottom of the movable plate 2, and the separation column 13 moves through the fixed plate 1. An operating plate 14 with a cross-section larger than the separation column 13 is provided at the bottom of the separation column 13.
[0029] This utility model provides a tarpaulin tensioning clamping mechanism. During on-site installation of the tarpaulin, the end of the tarpaulin without ropes is first fixedly connected to one side of the frame. Then, the part of the tarpaulin with ropes is placed between the fixed plate 1 and the movable plate 2. The clamping nut 4 is then rotated, driving the movable plate 2 closer to the fixed plate 1 until the movable plate 2 and the fixed plate 1 clamp the tarpaulin with ropes. Afterwards, a tensioner (a commercially available product, not the subject of this application) is used to connect a first connecting member 5 and one or two second connecting members 6. During subsequent tarpaulin traction, the first connecting member 5 is primarily responsible for traction. If the tarpaulin tilts or becomes misaligned during traction, the tensioners on one or both second connecting members 6 provide traction, thus allowing adjustment of the tarpaulin's angle and orientation without moving the tensioners. In practical use, the tensioner has one end used to pull the tarpaulin, while the other end is connected to a fixed tree or rock. Therefore, when the tension angle of the tensioner is not good, it is necessary to separate the outside of the tensioner from the tree or rock and then find a suitable tree or rock, which is quite cumbersome in practice. However, this application uses multiple angles to pull the fixing plate 1, so it only needs to be fixed once. Moreover, even if the direction or angle of the tarpaulin is not good after fixing, there is no need to adjust the position of the tensioner.
[0030] In another embodiment, the first connector 5 is pulled using a tensioner, while the second connector 6 is pulled manually after being connected to a rope. This can also tension the tarpaulin during installation; however, this method is mainly suitable for cases where the tarpaulin is small.
[0031] In actual operation, initially, there is a certain distance between the clamping nut 4 and the movable plate 2. The worker holds the fixed plate 1 with one hand and simultaneously pushes the operating plate 14 upwards with the fingers of that hand. The operating plate 14 raises the movable plate 2 via the separating column 13, separating the movable plate 2 from the fixed plate 1. Then, the other hand pulls the tarpaulin and places the part of the tarpaulin wrapped with ropes between the movable plate 2 and the fixed plate 1. After releasing the operating plate 14, the movable plate 2 falls. Finally, the worker uses a wrench to turn the clamping nut 4, which drives the movable plate 2 closer to the fixed plate 1. Ultimately, the anti-slip strip 7 presses the tarpaulin against the fixed plate 1, with the rope positioned between the anti-slip strip 7 and the support strip 8. When pulling the tarpaulin later, the anti-slip strip 7 acts as a locking mechanism for the rope, preventing the tarpaulin from separating from the fixed plate 1. This improves the pulling effect on the tarpaulin without applying excessive pressure. Meanwhile, the diameter of the support strip 8 is slightly smaller than the diameter of the anti-slip strip 7, so that after the tarpaulin is fixed, the fixed plate 1 and the movable plate 2 remain almost parallel. This can prevent excessive torque from being generated between the clamping nut 4 and the clamping screw 3.
[0032] Example 2
[0033] A tarpaulin tensioning clamping mechanism differs from Embodiment 1 in that, as Figures 4 to 7 As shown, the fixed plate 1 has two clearance holes 9, and the movable plate 2 has two rotating seats 10 on the side near the fixed plate 1. The support bar 8 moves through the rotating seats 10, and the rotating seats 10 are hinged to the support bar 8. The free end of the rotating seat 10 is located in the clearance hole 9.
[0034] The top of the movable plate 2 is provided with a protruding seat 11, and the clamping screw 3 moves through the middle of the protruding seat 11. The top of the protruding seat 11 is provided with an arc-shaped rotating groove. A fitting part 12 is movably sleeved on the clamping screw 3. The bottom of the fitting part 12 is movably attached to the inner wall of the rotating groove, and the top abuts against the clamping nut 4.
[0035] When clamping the tarpaulin, there is a certain distance between the clamping nut 4 and the mating part 12, allowing the movable plate 2 to rotate upwards. The holes in the middle of the protrusion 11, the mating part 12, and the movable plate 2 do not affect the normal swinging of the movable plate 2; the holes on the fixed plate 1 do not affect the normal swinging of the separating column 13. After the opening between the movable plate 2 and the fixed plate 1 is sufficiently large, the end of the tarpaulin with the rope is inserted between the fixed plate 1 and the movable plate 2. Then, the movable plate 2 is rotated to a horizontal position, and finally, the clamping nut 4 is rotated to press against the mating part 12. The mating part 12 presses down on the movable plate 2, thus fixing the angle of the movable plate 2.
[0036] The rotating groove at the top of the protruding seat 11 is arc-shaped, and the bottom of the mating part 12 is arc-shaped. Therefore, even if the movable plate 2 is not horizontal, the mating part 12 can be rotated at the corresponding angle so that its bottom fits the rotating groove and its top fits the clamping nut 4, preventing the clamping nut 4 from not being able to clamp the movable plate 2 tightly enough.
[0037] It should be understood that the diameters of the holes for the clamping screw 3 to pass through on the movable plate 2, the protrusion 11, and the mating part 12 are all larger than the diameter of the clamping screw 3. This means that even if the relative angle between the movable plate 2 and the fixed plate 1 changes, the movable plate 2, the protrusion 11, and the mating part 12 will not affect the normal rotation of the movable plate 2. Similarly, the holes on the fixed plate 1 are larger than the cross-section of the separating column 13, so that when the fixed plate 1 and the movable plate 2 rotate relative to each other, the separating column 13 will not be affected. Furthermore, the diagram is for illustrative purposes only and does not represent the actual structure.

Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
