Best Mode for Carrying Out the Invention

[0021] In the description of the present invention, it should be understood that if there are descriptions involving orientation, such as orientations or positional relationships indicated by up, down, front, back, left, and right, the orientation descriptions may be based on the orientations or positional relationships shown in the accompanying drawings. This is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0022] In the description of this utility model, if there is a quantity, "several" means one or more, "more" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of the terms "first" and "second" is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, or implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0023] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0024] As shown in Figures 1 to 4, the utility model discloses a tarpaulin windproof clamp, comprising a main body support plate 1, an elastic upper clamping plate 2 provided above the main body support plate 1 and connected to the rear end of the main body support plate 1 at one end, a lower clamping plate 3 provided below the rear end of the main body support plate 1, and a locking handle 4 provided in the middle of the elastic upper clamping plate 2. A baffle 5 is provided at the lower front end of the main body support plate 1, and the elastic upper clamping plate 2 includes an upper clamping portion 21 provided at the front end and an upper hand-holding portion 22 provided at the rear end. One end of the locking handle 4 is hinged with a rotating shaft 6, and the main support plate 1 is provided with a locking screw 7. One end of the locking screw 7 is fixedly connected to the main support plate 1, and the other end of the locking screw 7 passes through the elastic upper clamping plate 2 and is threadedly connected to the lower end of the rotating shaft 6. The middle part of the lower clamping plate 3 is hinged to the main support plate 1 and a torsion spring 8 is provided between the lower clamping plate 3 and the main support plate 1. The lower clamping plate 3 includes a lower clamping portion 31 at the front end and a lower hand-holding portion 32 at the rear end.

[0025] When fixing the tarpaulin, first press the upper handhold 22 of the elastic upper splint 2. Since the elastic upper splint 2 has a certain elasticity, the upper clamping part 21 will open a certain space upwards at this time, and then the tarpaulin is clamped between the upper clamping part 21 of the elastic upper splint 2 and the main support plate 1. When the upper handhold 22 is released, the upper clamping part 21 will initially clamp the tarpaulin, and then the locking handle 4 is rotated. The locking handle 4 cooperates with the locking screw 7 to make the elastic upper splint 2 firmly clamp the tarpaulin; the baffle 5 can cooperate with the lower clamping part 31 of the lower splint 3 to clamp and fix on the tubular object, and the shape of the tubular object is not restricted. The lower splint 3 is pressed open by the lower handhold 32, and the downward pressure strength changes, and the opening size also changes accordingly. Through this structure, it is possible to clamp strip tubular objects of different sizes and shapes.

[0026] The utility model has a simple structure, can firmly clamp tarpaulins of different thicknesses and can be fixed on tubular objects of different diameters or shapes, has better versatility, and is simple and convenient to operate.

[0027] In the present invention, the elastic upper clamping plate 2, the main body support plate 1 and the baffle 5 are an integrally formed structure, which is easy to manufacture.

[0028] In the utility model, two symmetrically arranged hinged lugs 11 are provided at the lower end of the main support plate 1, the middle part of the lower clamping plate 3 is hinged to the hinged lug 11 through a pin 9, and the torsion spring 8 is sleeved on the pin 9. The opening and closing control of the lower clamping plate 3 is realized by the torsion spring 8, thereby achieving the clamping effect of the lower clamping plate 3 and the baffle 5.

[0029] In the present invention, the locking handle 4 is provided with a rotating portion 41 at one end near the rotating shaft 6. The rotating portion 41 is provided with an eccentric hole, and the rotating shaft 6 is placed in the eccentric hole. The rotating portion 41 is provided with a limiting surface on the side away from the rotating shaft 6 that can be aligned with the main support plate 1 after rotation. In this way, the locking handle 4 can rotate upright when rotating and locking, and directly press down after rotating to a certain tightness. Since the rotating shaft 6 is eccentrically arranged, further compression can be achieved, and the limiting surface can play a limiting role to prevent the locking handle 4 from flipping over at will, which can achieve faster clamping of the elastic upper clamping plate 2.

[0030] In the present invention, the baffle 5 is tilted toward the rear end of the main support plate 1 , and the lower end clamping portion 31 is tilted toward the bottom of the lower clamping plate 3 , which provides a better clamping effect.

[0031] In the present invention, the lower end of the upper clamping portion 21 is provided with a plurality of parallel ribs, and the upper end of the main support is provided with grooves adapted to the ribs, which can play an anti-slip effect and ensure better clamping of the tarpaulin.

[0032] In the present invention, both the upper handle portion 22 and the lower handle portion 32 are provided with anti-slip protrusions to prevent slipping and facilitate operation.

[0033] In the present invention, a screw limiting portion is further provided at the lower end of the main support plate for limiting and fixing the locking screw. A nut is provided at the lower end of the locking screw. The screw limiting portion is used to limit and fix the nut to ensure that the locking screw is fixed on the main support plate.

[0034] The structure of the utility model is provided with an elastic upper clamping plate 2 and a lower clamping plate 3 which cooperate with the main support plate 1 respectively, so as to clamp the tarpaulin and fix it on the tubular object. In addition, the utility model can clamp tarpaulins of different thicknesses and fix them on tubular objects of different shapes or sizes, which greatly improves the versatility and can meet various different needs of outdoor camping.

[0035] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
