[0026] The end of the anti-off part 5 away from the buckling arm 4 is cylindrical, and a compression sleeve 6 is rotatably sleeved on the cylindrical part of the anti-off part 5.The middle part of the outer wall of the compression sleeve 6 is provided with an annular anti-off groove 7, and the top of the anti-off part 5 is provided with an L-shaped anti-off frame 8.The anti-off frame 8 is vertically and threadedly connected with an anti-off screw 9, and the bottom of the anti-off screw 9 is clamped to the top of the anti-off groove 7.

[0027] The width of the anti-off groove 7 is greater than the width of the anti-off screw 9.

[0028] The compression sleeve 6 has several inner walls, all of which are movably attached to the anti-disengagement part 5, and the diameters of different compression sleeves 6 are different.

[0029] The longitudinal section of the extension rod 1 is rectangular, and the movable sleeve 10 is attached to the extension rod 1, the inner wall of the movable sleeve 10 is movably attached to the outer wall of the extension rod 1, the side of the movable sleeve 10 close to the H-shaped steel is provided with a movable arm 11, the free end of the movable arm 11 is vertically provided with a temporary cylinder 12, the middle part of the temporary cylinder 12 is vertically provided with a temporary rod 13, the temporary rod 13 is located on both sides of the web plate of the anti-disengagement part 5, and the bottom of the temporary rod 13 abuts against the top of the lower flange.

[0030] The temporary rod 13 is threadedly connected with the temporary cylinder 12.

[0031] The bottom of the temporary rod 13 is provided with a drag-reducing cover 14 in the shape of a cover with an opening downward, the drag-reducing cover 14 is rotatably provided with a drag-reducing ball 15, the bottom of the drag-reducing ball 15 is lower than the bottom of the drag-reducing cover 14, and the temporary rod 13 abuts against the flange through the drag-reducing ball 15.

[0032] The top of the temporary rod 13 is horizontally provided with a rotating disc 16.

[0033] The top of the rotating disc 16 is provided with a fine adjustment hole 17 with a rectangular cross section, and further comprises an L-shaped fine adjustment part 18, one end of the fine adjustment part 18 is matched with the fine adjustment hole 17, and the fine adjustment part 18 is detachably connected with the rotating disc 16.

[0034] The bottom of the movable arm 11 is movably attached to the top of the extension rod 1.

[0035] The utility model provides a kind of tent cloth installation is used in tension auxiliary supporting appliance, first should understand is that the present application is only applicable to I-beam (or T-beam);When using, the horizontal portion of the buckling arm 4 is moved to the below of I-beam, then vertically upwardly raise supporting appliance, and make the horizontal portion of the buckling arm 4 adhere to the bottom of I-beam, then move the entire supporting appliance towards the direction of extension rod 1, and until the opening formed by anti-dropping part 5 and buckling arm 4 is buckled to the edge of wing plate, at this time, it makes that supporting appliance can be temporarily stably connected with I-beam temporarily;Then one end of tensioner (prior art, not too much here) is fixedly connected with connecting ring 2 (located on the outside of tent cloth frame), the other end is fixedly connected with the clamp of tent cloth edge (also not the object of the present application), then tensioner can be started, the total length of tensioner gradually changes, and the clamp is pulled to the outside of tent cloth frame, and until the edge of tent cloth is pulled to the outside of tent cloth frame, tent cloth is tensioned, then tent cloth can be fixed to tent cloth frame. Wherein, when the supporting appliance of the present application is subjected to the upward tension of tensioner, the bottom of buckling arm 4 and anti-dropping part 5 are buckled to the wing plate of I-beam, so that the supporting appliance can provide the support force or fulcrum of tensioner, so that tensioner can normally exert force and tension tent cloth. The action fulcrum of the supporting appliance of the present application is based on the structure of tent cloth frame itself, and there is no requirement for external structure, so that the use effect is better, and the use limitation is lower.

[0036] Wherein, after buckling arm 4 is buckled to the bottom of I-beam, and the pressing sleeve 6 of the outer wall of anti-dropping part 5 is pressed on the top of wing plate, the worker can also move the movable sleeve 10 towards the web direction, until the temporary rod 13 is located above the wing plate, one end of the fine adjustment piece 18 is inserted into the fine adjustment hole 17, and the drag reduction ball 15 can be abutted on the top of wing plate by slightly rotating the rotating disc 16, so that the entire supporting appliance can be naturally stable with I-beam at this time, without the need for worker to grasp or fix, but can perform other operations, and the operation convenience is higher. At the same time, when extension rod 1 is subjected to upward tension, temporary rod 13 is not subjected to force at this time, so that the part of temporary rod 13 can have longer service life.

[0037] It should also be understood that the thickness of the wing plate of I-beam is not fixed, but has certain change, so that the pressing sleeve 6 is not cylindrical, but is circular truncated cone with different diameters at two ends, for better adhesion on the wing plate (the drawing is only schematic, not representative of the actual).

[0038] Wherein since the tarpaulin frame is not a standard part, the channel steel is also not fixed, not only the size of the channel steel, but also the shape is different; For example, some channel steel is straight, and some is downward arc, at this time, different diameter of the compression sleeve 6 needs to be selected according to the actual situation. For example, if the thickness of the wing plate is large, a compression sleeve 6 with smaller diameter is selected; If the arc of the channel steel is large, a compression sleeve 6 with smaller diameter also needs to be selected, so as to be suitable for the shape of the channel steel.

[0039] When adjusting the compression sleeve 6, only need to rotate the anti-off screw 9, then the compression sleeve 6 can be directly taken out from the cylindrical part of the anti-off part 5, then the new compression sleeve 6 is sleeved, finally the anti-off screw 9 is rotated and the bottom of the anti-off screw 9 is located in the anti-off groove 7. The width of the anti-off groove 7 is greater than the width of the anti-off screw 9, so that the compression sleeve 6 can be rotated more easily, and the force acting on the anti-off screw 9 is smaller, so that the position stability of the compression sleeve 6 is better. The compression sleeve 6 is made of steel material, which has enough strength. At the same time, the anti-off part 5 has a magnet at the bending part, which can provide a pulling force to the compression sleeve 6, so that the compression sleeve 6 can be kept in close contact with the anti-off part 5 before being buckled to the channel steel.

[0040] When the wing plate with different thickness is used, the position of the temporary rod 13 also needs to be adjusted. When the adjustment range is large, the worker only needs to manually rotate the rotating disc 16. Then after the adjustment is completed, only a slight rotation of the rotating disc 16 is needed each time, at this time the fine adjustment part 18 can be operated, and enough force can be applied to the rotating disc 16, and the drag-reducing ball 15 can be stably abutted on the top of the wing plate. Since the movable sleeve 10 can slide on the extension rod 1, even different types of channel steel and anti-off screw 9 can be used normally.

[0041] The two buckling arms 4 have a certain distance between them, so not only the supporting strength of the whole supporting tool can be improved, but also the connection stability between the whole supporting tool and the channel steel can be improved. Even if the channel steel is arc-shaped or wave-shaped, the supporting tool can be connected with the channel steel. At the same time, the bottom of the buckling arm 4 is cylindrical, so no matter what the shape of the channel steel is, the buckling arm 4 can be well fitted on the bottom of the channel steel.

[0042] The above description is only a description of the preferred embodiment of the utility model, and does not limit the scope of the utility model. Any change or modification made by the ordinary skilled in the art according to the above disclosure is within the protection scope of the claims.
