[0023] The present invention is further described in detail below with reference to the embodiments given in the accompanying drawings.

[0024] Example 1: See Figure 1-5 As shown, a one-piece side guard plate of a through channel includes two groups of drum components 1, two groups of rotating shaft components 2, a guard plate 3 and a baffle 5. The drum component 1 includes a drum 11 and two rotating sleeves 12. The rotating sleeves 12 are welded to the upper and lower ends of the drum 11. The rotating sleeves 12 are provided with two unlocking holes 13. The rotating shaft component 2 includes a rotating shaft 21 and a torsion spring 22. The rotating shaft 21 passes through the two rotating sleeves 12 and is rotatably connected to the rotating sleeves 12. The torsion spring 22 is located in the drum 11 and is sleeved on the rotating shaft 21. Both sides of the guard plate 3 are bent to fit the outer peripheral shape of the drum 11 and are fixed to the corresponding outer periphery of the drum 11 by bolts. The baffle 5 is respectively fixed to both ends of the guard plate 3 by bolts. The contact surfaces of both sides of the baffle 5 with the outer periphery of the drum 11 are corrugated.

[0025] See also Figure 3 , 4 As shown, a notch 111 is provided on the reel 11, and a mounting seat 6 is fixedly connected to the rotating shaft 21 at the notch 111. One end of the mounting seat 6 has a clamping block 61 and a first clamping bolt 62. The clamping block 61 is provided with a hole for the rotating shaft 21 to pass through, and a through groove is provided on the outside of the hole. The rotating shaft 21 extends into the hole, and the first clamping bolt 62 passes through the through groove to lock the rotating shaft 21.

[0026] See also Figure 1 and 3 As shown, the torsion spring pressure plate 7 also includes two torsion spring pressure plates 7, one of which is fixed on the rotating shaft 21, and the other is fixed on the lower rotating sleeve 12, and respectively presses the two ends of the torsion spring 22. The torsion spring pressure plate 7 is provided with a set hole 71, which is set on the rotating shaft 21, and the torsion spring pressure plate 7 is provided with a radial through groove 72 and a second clamping bolt 73, and the second clamping bolt 73 passes through the radial through groove 72 for locking. The torsion spring pressure plate 7 is disc-shaped, sleeved on the rotating shaft 21, and fixed on the rotating shaft 21 by the second clamping bolt 73, so that the torsion spring 22 remains in position and applies torque to the reel 11.

[0027] The two sets of rotating shafts 21 of the present invention are fixedly connected to the vehicle body through the mounting seat 6, and the torsion spring 22 applies a torsion force to the reel 11. The torsion forces applied by the two sets of torsion springs 22 to the corresponding reels 11 are in opposite directions, thereby tensioning the reel 11, and the rotational force of the two reels 11 tightens the guard plate 3. Compared with the prior art, the present invention has a simple structure and a small installation space.

[0028] See also Figure 6-8As shown, a one-piece side guard assembly and disassembly tool for a through-channel comprises a rotating base 8, two torsion shafts 9, a worm wheel 10 and a worm 20. The two torsion shafts 9 are fixedly connected to the lower part of the rotating base 8. The worm wheel 10 is rotatably assembled in the rotating base 8. The worm 20 is rotatably connected to the rotating base 8 and meshes with the worm wheel 10. The cross-section of the outer end of the rotating shaft 21 is hexagonal. The worm wheel 10 is provided with a polygonal hole 30. The polygonal hole 30 is a hexagonal hole. When unlocking is required, the polygonal hole 30 is sleeved on the outer end of the rotating shaft 21 to fix the worm wheel 10. The two torsion shafts 9 are inserted into the two unlocking holes 13 of the rotating sleeve 12, and the worm 20 is rotated to drive the reel 11 to rotate.

[0029] See also Figure 8 As shown, two outwardly extending worm seats 81 are provided on one side of the rotating base 8. The worm seats 81 are provided with holes and partially expose the worm wheel 10. Both ends of the worm 20 extend into the holes respectively to be rotatably connected to the worm seats 81 and mesh with the worm wheel 10.

[0030] See also Figure 7-8 As shown, the two ends of the worm 20 have worm unlocking holes 211 for the wrench to be inserted into. The worm unlocking holes 211 are quadrilateral holes.

[0031] See also Figure 7 As shown, the upper end of the rotating base 8 is fixedly connected with an end cover 82, so as to facilitate the installation of the worm gear 10.

[0032] When the assembly and disassembly tool of the present invention is operated, the unlocking guard plate 3 mainly overcomes the torsion force of the torsion spring 22, thereby rotating the reel 11. Therefore, this solution is based on the fixed rotating shaft 21, see Figure 2 As shown, the polygonal hole 30 is sleeved on the outer end of the rotating shaft 21 to fix the worm wheel 10. The two torsion shafts 9 are inserted into the two unlocking holes 13 of the rotating sleeve 12, and the worm 20 is rotated to drive the rotating base 8 to rotate, thereby driving the reel 11 to rotate, so that the reel 11 overcomes the torsion of the torsion spring 22, and the mounting bolts 4 that fix the guard plate 3 are rotated to a certain position to an operable position in the through channel, and the mounting bolts 4 are removed to achieve the purpose of unlocking and removing the guard plate 3. The assembly and disassembly tool has a compact structure and can be unlocked without much operating space. During installation, the above method is also used, and the assembly and disassembly tool can be rotated in the opposite direction.

[0033] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
