Detailed Embodiments

[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1 to 4, the present utility model provides a technical solution: a vehicle-mounted insulating ladder fixing device, including a bracket 1 and two retaining pieces 3 mounted on the bracket 1. One of the retaining pieces 3 is movably mounted on the bracket 1, and the other retaining piece 3 is fixedly mounted on the bracket 1. A chute 7 is provided at the top of the bracket 1. By providing the chute 7, the position of the retaining piece 3 can be adjusted, so as to adapt to insulating ladders of different widths and improve applicability. One of the retaining pieces 3 is slidably connected to the chute 7. Arc-shaped grooves 5 are provided on the adjacent sides of the two retaining pieces 3. A receiving groove 16 is provided on the inner wall of the arc-shaped groove 5, and a clamping groove 19 is provided on the inner wall of the receiving groove 16. An arc-shaped piece 6 is hinged to the retaining piece 3. By providing the two retaining pieces 3, the insulating ladder cannot move left and right. The cooperation between the arc-shaped piece 6 and the retaining piece 3 makes the insulating ladder unable to move up and down. And by providing a support cylinder 9 and a screw rod 13, the claw 10 is pressed tightly against the insulating ladder, so that the insulating ladder cannot move forward and backward, thereby realizing the fixation of the insulating ladder, ensuring that the insulating ladder is firmly fixed, and avoiding the situation of the insulating ladder slipping. A clamping block 20 matching with the clamping groove 19 is provided on the outer side of the arc-shaped piece 6. The cooperation between the clamping block 20 and the clamping groove 19 is used to fix one end of the arc-shaped piece 6 to prevent the arc-shaped piece 6 from rotating. A support column 8 is rotatably mounted at the top of the bracket 1, and a support cylinder 9 is rotatably connected to the support column 8. By rotating the support cylinder 9, the screw rod 13 can move, and the screw rod 13 drives the claw 10 to move, so as to facilitate the claw 10 to press tightly against the insulating ladder. The support cylinder 9 is internally threadedly connected with a screw rod 13, and one end of the screw rod 13 is hinged to a claw 10.

[0019] Wherein, avoidance grooves 4 are provided at the tops of the two retaining pieces 3. The avoidance grooves 4 are used to avoid the arc-shaped piece 6 to prevent the arc-shaped piece 6 from being blocked by the retaining piece 3 and unable to be opened normally.

[0020] Wherein, a baffle 21 is provided on the outer side of the retaining piece 3. The width of the baffle 21 is greater than the width of the chute 7, so that the baffle 21 cannot pass through the chute 7, thereby preventing the retaining piece 3 from moving up and down. A threaded hole 22 is provided on the baffle 21, and a bolt 12 is threadedly connected to the threaded hole 22. The bolt 12 is used to fix the retaining piece 3 sliding in the chute 7 to prevent the retaining piece 3 from moving.

[0021] Wherein, a plurality of through holes 14 are provided through the bracket 1. By providing the plurality of through holes 14, the retaining piece 3 can be fixed at different positions. The bolt 12 passes through the through hole 14 and is connected to the threaded hole 22.

[0022] Wherein, a partition 2 is integrally formed on the inner side wall of the bracket 1. The partition 2 can improve the structural strength of the bracket 1, and the bottom of the retaining piece 3 is in contact with the partition 2, which can play a certain supporting role for the retaining piece 3. A pin shaft 17 is mounted on the bracket 1, and the pin shaft 17 is used to fix one of the retaining pieces 3 to prevent the retaining piece 3 from moving.

[0023] Among them, the support 1 is respectively provided with a rope-passing hole 11, a fixing hole 15 and a hanging hole 18 penetrating through it. By using a screw to pass through the fixing hole 15, the support 1 can be fixed on the pickup truck. When fixing the insulating ladder, a rope can be taken, one end of the rope is passed through the rope-passing hole 11 for fixation, and then the insulating ladder is tied and fixed with the rope. After the tying is completed, the other end of the rope passes through the hanging hole 18 and the rope-passing hole 11 in sequence for fixation, so that the insulating ladder can be fixed with the rope, further improving the firmness of the fixation of the insulating ladder. The fixing hole 15 is located below the partition 2, and the rope-passing hole 11 and the hanging hole 18 are located above the partition 2.

[0024] Specifically, when in use, take a screw to pass through the fixing hole 15 to fix the support 1 on the pickup truck, then rotate the arc-shaped piece 6 to open it, place the insulating ladder on the support 1, make the ladder beam of the insulating ladder close to the stop piece 3 fixedly installed on the support 1, then move the other stop piece 3 to make the other stop piece 3 close to the other ladder beam of the insulating ladder, pass the bolt 12 through the through hole 14 and screw it into the threaded hole 22 to fix the other stop piece 3. Subsequently, rotate the arc-shaped piece 6 to close it, and the clamping block 20 is inserted into the clamping groove 19 to fix the arc-shaped piece 6. Then pull the insulating ladder until the cross bar of the insulating ladder is blocked by the arc-shaped piece 6. Subsequently, rotate the support cylinder 9 clockwise by 90 degrees with the support column 8 as the center, and the support cylinder 9 is perpendicular to the support 1, and rotate the abutting claw 10 to make it rotate into a vertical state. Then, hold the support cylinder 9 with one hand and hold the abutting claw 10 with the other hand. Under the rotation of the support cylinder 9, the screw rod 13 moves, and the screw rod 13 drives the abutting claw 10 to move until the abutting claw 10 abuts tightly against the cross bar of the insulating ladder, and the fixation of the insulating ladder can be completed. Finally, a rope can also be used to pass through the rope-passing hole 11 and the hanging hole 18 to reinforce the insulating ladder, further improving the firmness of the fixation of the insulating ladder.
