During installation, the steel wire passes through the slide groove 31 to act on the slider 6, and the wire adjusting nut 5 is installed on the screw rod 3. The slider 6 is driven to move by adjusting the wire adjusting nut 5, so as to adjust the tightness of the steel wire.

[0022] The assembly process of the film pulling member of the utility model is as follows: 1. Insert the slider 6 from the front end gap of the slide groove 31, and then screw the wire adjustment nut 5 onto the screw rod 3; 2. Connect the front end of the screw rod 3 to the steel plate.

[0023] After the above assembly is completed, when installing the membrane cloth, first punch holes on the membrane cloth at the installation point so that the bolts can pass through the membrane cloth, and then install the membrane cloth between the upper steel plate 1 and the lower steel plate 2 by means of bolts and nuts; then pass the steel wire through the steel wire hole 12 on one side, the slide groove 31 and the steel wire hole 12 on the other side in turn, and then adjust the position of the steel wire adjustment nut 5, and drive the slider 6 to move outward through the steel wire adjustment nut 5, so as to tighten the steel wire; finally, screw the membrane cloth fixing nut 8 from the outside of the screw rod 3 until the membrane cloth fixing nut 8 hits the steel plate 7 at the end of the main structure, so as to tighten the membrane cloth. After the installation is completed, the tightness of the steel wire rope can be further adjusted by adjusting the position of the steel wire adjustment nut 5, so as to change the tension of the membrane cloth.

[0024] As a preferred embodiment of this embodiment, a plurality of corresponding connecting holes are provided on the upper steel plate 1 and the lower steel plate 2. When installing the membrane cloth, the bolts are passed through the upper steel plate 1, the membrane cloth and the lower steel plate 2, and finally the nuts are tightened to fix the membrane cloth at the installation point between the upper steel plate 1 and the lower steel plate 2.

[0025] As a preferred embodiment of the present embodiment, the upper steel plate 1 and the lower steel plate 2 are an integral structure, and both sides of the upper steel plate 1 and the lower steel plate 2 constitute wire holes 12 for installing steel wires. During installation, the steel wire can be passed through the wire hole on one side, the slide groove 31 and the wire hole on the other side in sequence, which makes installation more convenient.

[0026] As a preferred embodiment of this embodiment, the front end of the screw rod 3 is connected to the lower steel plate 2 through the connecting pin 4. During assembly, it is only necessary to make the connecting pin 4 pass through the lower steel plate 2 and the screw rod 3, and finally lock the connecting pin 4 through the pin, which is convenient for assembly.

[0027] As a preferred embodiment of this embodiment, the action surface between the slider 6 and the steel wire is arc-shaped, which can prevent damage to the steel wire rope during the process of tightening the steel wire rope, increase the service life of the steel wire rope, and reduce the material cost of the steel wire rope.

[0028] As a preferred embodiment of this embodiment, square grooves are provided on the upper and lower sides of the middle part of the slider 6. The slider 6 is installed in the slide groove 31 at the front end of the screw rod 3 through the square groove in the middle part of the slider 6, so that the slider 6 slides axially along the slide groove 31. In this way, the slider 6 can only move axially along the slide groove 31, thereby preventing the slider 6 from being offset and causing friction damage to the wire rope during the process of tightening the wire rope.

[0029] As a preferred embodiment of this embodiment, a gasket 9 is arranged between the membrane cloth fixing nut 8 and the end steel plate 7 of the main structure. The gasket 9 can increase the connection strength of the membrane cloth fixing nut 8 and play a reinforcing role to prevent the membrane cloth fixing nut 8 from falling off and causing the membrane cloth to loosen.
