[0039] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0040] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0041] Reference Figure 1-2 The present embodiment provides an installation tool for a duct flange clamp, which includes: a handle 1, an installation card 2 and a correction card 3. The handle 1 and the correction card 3 are respectively located on both sides of the installation card 2. The correction card 3 and the installation card 2 are respectively provided with a correction groove 3a and an installation groove 2a which are concavely opposite to each other. The correction groove 3a is used to correct the common plate flange 5 of the flange clamp 4 to be installed, and the installation groove 2a is used to install the flange clamp 4.

[0042] The mounting card 2 includes a card plate 1 2b, a positioning plate 2c and a card plate 2 2d, which are connected in sequence to form a mounting groove 2a, and the length of the card plate 1 2b is greater than the length of the card plate 2d. The positioning plate 2c is used to install the handle 1, the card plate 1 2b and the card plate 2 2d. The mounting groove 2a formed by the connection of the card plate 1 2b, the positioning plate 2c and the card plate 2 2d is adapted to the shape of the flange clamp 4. When in use, the shortest side of the flange clamp 4 is clamped on the common plate flange 5, and the mounting groove 2a is buckled on the outside of the flange clamp 4, so that the card plate 2 2d, the positioning plate 2c and the card plate 1 2b are respectively against the shortest side, the middle short side 1 and the middle short side 2 of the flange clamp 4, and the handle 1 is rotated to drive the flange clamp 4 to rotate around the connection point of the shortest side and the middle short side 1, and the longest side of the flange clamp 4 is pushed to be clamped and fixed with the common plate flange 5.

[0043] According to the shape of the flange clamp 4, the second clamping plate 2d can be configured as an arc-shaped plate with the concave surface facing the first clamping plate 2b, and the angle formed by the first clamping plate 2b and the positioning plate 2c can be configured as an obtuse angle. The former facilitates the second clamping plate 2d to fix the shortest side of the flange clamp 4 on the common plate flange 5, and ensures that during the rotation of the device, the second clamping plate 2d and the shortest side of the flange clamp 4, and the shortest side of the flange clamp 4 and the common plate flange 5 will not fall off, avoiding installation failure; the latter is to better fit the shape of the flange clamp 4, and to facilitate the efficiency of installing the longest side of the square tube flange clamp.

[0044] Reference Figure 2-4 The correction card 3 in this embodiment includes a card plate 3 3b and a card plate 4 3c. The card plates 3 3b and 3c are perpendicular to each other. Card plates 1 2b, 3b and 3c are connected in sequence to form a correction groove 3a. The concave side of the correction groove 3a faces the installation groove 2a. Card plates 1 2b and 3b are movably connected through a positioning pin 6 to change the opening of the correction groove 3a. When the common plate flange 5 is found to be bent and deformed, the bent and deformed common plate flange 5 can be inserted into the correction groove 3a, and the handle 1 can be rotated to make the entire installation tool and the common plate flange 5 rotate synchronously to correct the common plate flange 5 to the correct angle.

[0045] The length of the fourth card plate 3c should not be less than the width of the common plate flange 5, so that the correction groove 3a can completely surround the common plate flange 5, and avoid the edge of the fourth card plate 3c hitting the plate surface of the common plate flange 5 and making its surface uneven during the rotation of the tool. In order to prevent the end of the fourth card plate 3c from affecting the installation work of the mounting groove 2a, the length of the first card plate 2b can be appropriately increased to avoid the installation groove 2a being unable to be snapped onto the outside of the flange clamp 4 due to the influence of the end of the fourth card plate 3c. Of course, the above-mentioned positioning pin 6 is used to adjust the angle between the third card plate 3b and the first card plate 2b, increase the opening of the correction groove 3a, and make the end of the fourth card plate 3c away from the mounting groove 2a. During implementation, a connecting block 1 7 and a connecting block 2 8 can be respectively set at the proximal ends of the card plate 1 2b and the card plate 3 3b, and a rotating shaft 9 connected to the connecting block 1 7 is provided, and a positioning pin 6 is passed through the connecting block 2 8 and the rotating shaft 9. When the positioning pin 6 is removed, the rotating shaft 9 can be rotated to change the angle between the card plate 1 2b and the card plate 3 3b.

[0046] Specifically, Figure 4 As shown, a positioning groove 10 and a positioning groove 2 11 are respectively provided in the rotating shaft 9 and the connecting block 2 8. The positioning groove 10 and the positioning groove 2 11 are coaxially arranged. A tension spring 12 is provided at the bottom of the positioning groove 10. The end of the positioning pin 6 passes through the positioning groove 2 11 and is connected to the tension spring 12. When the positioning pin 6 is pulled outward to disengage from the positioning groove 10, the rotating shaft 9 can rotate. When the external pulling force is eliminated, the positioning pin 6 automatically falls back into the positioning groove 10 under the action of the tension spring 12, and the rotating shaft 9 cannot rotate.

[0047] For the convenience of operation and positioning, the cross section of the positioning pin 6 can be configured as a straight line or a cross, and the shapes of the positioning groove 10 and the positioning groove 2 11 are adapted thereto.

[0048] To prevent the shaft 9 from being separated from the connecting block 2 8 , a clamping block 13 is provided at the end of the positioning pin 6 away from the shaft 9 . The radial dimension of the clamping block 13 is larger than the radial dimension of the positioning groove 2 11 , so as to tightly connect the connecting block 1 7 and the connecting block 2 8 .

[0049] Reference Figure 1 The handle 1 includes a connecting rod 1a and a holding rod 1b. The outer wall of the holding rod 1b is provided with an anti-slip convex point 1c. The two ends of the connecting rod 1a are respectively connected to the positioning plate 2c and the holding rod 1b. The concave side of the connection between the connecting rod 1a and the holding rod 1b faces the clamping plate 2b to save force when installing the flange clamp 4 and improve construction efficiency.

[0050] How to use this installation tool: Refer to the attached Figure 5-6Before installing the flange clamp 4, observe whether the common plate flange 5 is perpendicular to the axis of the air duct, that is, observe whether the common plate flange 5 is bent and deformed. If so, extend the completely deformed common plate flange 5 into the correction groove 3a, and rotate the handle 1 to correct it to the correct angle; after the common plate flange 5 is corrected or no correction is needed, clamp the shortest side of the flange clamp 4 on the common plate flange 5, buckle this tool on the outside of the flange clamp 4, and use the intersection of the shortest side and the middle short side of the flange clamp 4 as the rotation center, rotate this tool and the flange clamp 4, and push the longest side of the flange clamp 4 until it is clamped on the common plate flange 5.

[0051] Compared with the prior art, the beneficial effects of the utility model are: providing an installation tool for a flange clamp 4, which can correct the angle of the common plate flange 5 before installing the flange clamp 4, thereby avoiding the situation where the surface of the common plate flange 5 is uneven and air leaks due to manual hammering; the flange clamp 4 can be installed quickly and labor-savingly, thereby improving construction efficiency; and the opening of the correction groove 3a is variable. By adjusting its opening, the influence of the correction groove 3a structure on the operation when installing the flange clamp 4 can be avoided, thereby improving the practicality of the tool.

[0052] The above are preferred implementations of the present utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications should also be regarded as the protection scope of the present utility model.
