DETAILED DESCRIPTION

[0029] The utility model will now be further described in detail with reference to the accompanying drawings.

[0030] See also Figure 1-5As shown, in this embodiment, an insulating telescopic ladder for power engineering maintenance is provided, including a bamboo ladder 1, a plurality of telescopic footrests 2 are installed inside the bamboo ladder 1, two telescopic slots 3 are provided on the lower side of the bamboo ladder 1, the inner walls of the two telescopic slots 3 are rotatably matched with lifting screws 4, the two lifting screws 4 are threadedly matched with adjustment blocks 5 that are slidably matched with the telescopic slots 3, the lower sides of the two adjustment blocks 5 are provided with ball head slots 6, the inner walls of the ball head slots 6 are rotatably matched with ball head rods 7, and the lower ends of the two ball head rods 7 are fixedly connected with abutment blocks 8;

[0031] A driving assembly 9 matched with the lifting screw rod 4 is installed inside the telescopic slot 3, and hand screws 10 that abut against the ball head rod 7 are threadedly matched on the opposite sides of the two adjustment blocks 5. An adjustment mechanism 11 is installed on the inner wall of the bamboo ladder 1.

[0032] One aspect of the application of this embodiment is as follows: when in use, the bamboo ladder 1 is first unfolded, and the bamboo ladder 1 is composed of two telescopic frames and a plurality of telescopic footrests 2. Then the bottom of the bamboo ladder 1 is abutted against the ground, and the upper side of the bamboo ladder 1 is close to a hard object to achieve tilted support for easy use by people;

[0033] When inspecting the circuit on the uneven ground, the worm gear 901 can be driven to rotate by rotating the worm 902, and then the worm gear 901 drives the adjustment block 5 to move, so that the two abutting blocks 8 can be adjusted to extend to different lengths, so as to be suitable for different heights of the ground, and then the abutting block 8 can be rotated in the ball head groove 6 by loosening the hand screw 10, so that the abutting block 8 fits the uneven ground, and the ball head rod 7 in the ball head groove 6 can be fixed after tightening the hand screw 10, so as to ensure that the ladder body does not remain tilted when used on the uneven ground, thereby improving the scope of application of the device for road conditions;

[0034] When the storage space is small, the operating button 113 can be turned to adjust the bolt 112 in the threaded sleeve 111, so that the multiple telescopic footrests 2 can be mobilized to shrink, the overall width can be narrowed, and the occupied space can be further reduced, which relatively improves the convenience of placement.

[0035] The telescopic footrest 2 of this embodiment includes a hollow rod 201 fixedly connected to a side close to the bamboo ladder 1, and a telescopic rod 202 slidingly fitted on the inner wall of the hollow rod 201 and fixedly connected to the bamboo ladder 1. When the adjustment mechanism 11 is operated, the telescopic rod 202 will be correspondingly extended and retracted in the hollow rod 201.

[0036] The driving assembly 9 of this embodiment includes a worm wheel 901 fixedly connected to the lifting screw 4, a worm 902 rotatably fitted on one side of the inner wall of the telescopic slot 3 and meshing with the worm wheel 901, and a button ring 903 fixedly connected to one end of the worm 902. The button ring 903 rotates to drive the worm 902 to rotate, and when the worm 902 rotates, it can push the adjustment block 5 to move up and down.

[0037] The adjustment mechanism 11 of this embodiment includes a threaded sleeve 111 fixedly connected to one side of the inner wall of the bamboo section ladder 1, an adjusting bolt 112 threadedly engaged inside the threaded sleeve 111 and rotatably engaged with the other side of the inner wall of the bamboo section ladder 1, and an operating button 113 fixedly connected to the adjusting bolt 112. By rotating the operating button 113, the adjusting bolt 112 is moved in the threaded sleeve 111, thereby adjusting the overall width.

[0038] The lower sides of the two supporting blocks 8 of this embodiment are each provided with a plurality of V-shaped grooves 12, and the ball head rod 7 is each provided with a plurality of anti-skid grooves 13. When the supporting blocks 8 come into contact with the ground, they are stuck into the ground through the V-shaped grooves 12 to increase the anti-skid property of the bottom. The anti-skid grooves 13 can facilitate the friction force after the hand-tightening bolts 10 and the ball head rod 7 are released, making it more firm after being squeezed.

[0039] The adjusting bolt 112 of this embodiment is threadedly matched with a reinforcing button 14, which abuts against one end of the threaded sleeve 111. After the width is adjusted, the reinforcing button 14 is rotated to abut against the threaded sleeve 111, thereby improving the stability between the adjusting bolt 112 and the threaded sleeve 111.

[0040] In this embodiment, an anti-slip groove 15 is provided on one side of the inner wall of the two telescopic grooves 3, and the inner wall of the anti-slip groove 15 is slidably matched with an anti-slip block 16 fixedly connected to the adjusting block 5. When the adjusting block 5 moves up and down, the anti-slip block 16 slides in the anti-slip groove 15, which can prevent the adjusting block 5 from detaching from the telescopic foot pedal 2.

[0041] The present invention is not limited to the above-mentioned implementation modes. Anyone should be aware of the structural changes made under the inspiration of the present invention. Any technical solution that is the same or similar to the present invention falls within the protection scope of the present invention. The technology, shape, and structure that are not described in detail in the present invention are all known technologies.
