AI Technical Summary
When used on column-type support, existing telescopic ladders are prone to pouring and falling off because there is a lack of positioning devices for column-to-protecting columns.
A telescopic ladder flat belt is designed, including a telescopic ladder body with a mounting area on the top. A squid piece abutting on the column is installed in the installation area in the installation area. A partial arc section is provided on the squid piece, and the column is distributed on the inside of the arc section, and is equipped with an anti-slip pad and a rotating mechanism to ensure stable contact between the squid piece and the column.
Through the limit of the arc segment and the anti-slip effect of the anti-slip pad, the telescopic ladder body is avoided from displacement, pouring and falling off on the column, improving the safety of use.

DETAILED DESCRIPTION
[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] refer to Figure 1-2 As shown, the utility model provides a telescopic ladder flat belt, comprising: a telescopic ladder body 1 with an installation area on the top, a flat belt piece 2 abutting against a column is horizontally installed in the installation area, the flat belt piece 2 is provided with at least a partial arc segment 3, and the columns are distributed on the inner side of the arc segment 3.
[0028] As mentioned above, when using the telescopic ladder body 1 and the flat belt member 2 provided by the utility model, the flat belt member 2 is made of a strip-shaped aluminum alloy material, and the flat belt member 2 is installed at the top of the telescopic ladder body 1. When the top of the telescopic ladder body 1 is close to the column, the column is placed in the arc segment 3 on the flat belt member 2, so that the flat belt member 2 is prevented from being displaced at the column through the arc segment 3, thereby preventing the telescopic ladder body 1 from tipping over and falling off.
[0029] The flat belt member 2 can be used for a telescopic ladder and can also be used for equipment for climbing, such as a straight ladder and a bamboo ladder.
[0030] In the present utility model, combined with Figure 2 and Figure 4-5 As shown, an anti-skid pad 4 for anti-skid is also installed on the inner side of the arc segment 3 of this embodiment, and a connected recessed hole 11 and a third threaded hole 16 are successively opened between the anti-skid pad 4 and the arc segment 3, and a third fastening bolt 12 is provided in the recessed hole 11 and the third threaded hole 16.
[0031] As mentioned above, when the anti-skid pad 4 provided by the utility model is used, when the flat belt member 2 contacts the column, the anti-skid pad 4 plays an anti-skid role between the flat belt member 2 and the column to prevent slipping between the flat belt member 2 and the column. The anti-skid pad 4 is made of PVC material, and the anti-skid pad is detachably installed on the flat belt member through the recessed hole 11, the third fastening bolt 12 and the third threaded hole 16.
[0032] In the present utility model, combined with Figure 1-3 As shown, rotating mechanisms are installed on the inner walls on both sides of the top of the telescopic ladder body 1 of this embodiment, and an installation area for installing the flat belt member 2 is formed between the two rotating mechanisms. The two rotating mechanisms are used to drive the flat belt member 2 to rotate axially.
[0033] Combination Figure 6 As shown, the rotating mechanism includes a mounting seat 10 and a rotating seat 7. A rotating groove 13 for accommodating the rotation of the rotating seat 7 is opened on the side of the mounting seat 10 away from the telescopic ladder body 1. The mounting seat 10 is detachably mounted on the inner wall of the telescopic ladder body 1, and the mounting area is formed between the two rotating seats 7.
[0034] As mentioned above, when using the rotating mechanism provided by the utility model, the mounting seat 10 in the rotating mechanism provides a mounting position for the rotating seat 7 on the telescopic ladder body 1, and the rotating seat 7 can be rotated on the mounting seat 10 through the rotating groove 13. Since the flat belt member 2 is detachably installed between the two rotating seats 7, when the rotating seat 7 rotates, the flat belt member 2 is driven to rotate, so that when the flat belt member 2 leans against the column, the surface of the flat belt member 2 is closely fitted with the column, thereby improving the stability of the contact between the flat belt member 2 and the column.
[0035] Further, in order to allow the flat belt member 2 to be detachably mounted on the rotating seat 7, refer to Figure 2-4 As shown, both ends of the flat belt member 2 are horizontally extended outward with a bent portion 6, each bent portion 6 is installed with a first fastening bolt 5, and the rotating seat 7 is provided with a first threaded hole 14 for accommodating the first fastening bolt 5. The bent portion 6 facilitates the installation of the flat belt member 2 between the two rotating seats 7, and the bent portion 6 is fixedly installed on the rotating seat 7 through the first fastening bolt 5 and the first threaded hole 14. At the same time, since the bent portion 6 and the flat belt member 2 are at an angle of 90 degrees, the flat belt member 2 can rotate with the rotating seat 7, and the flat belt member 2 can be replaced after the first fastening bolt 5 is removed.
[0036] Further, in order to allow the mounting base 10 to be detachably mounted on the telescopic ladder body 1, refer to Figure 3 and Figure 6As shown, mounting ears 9 are installed at both symmetrical ends of the mounting seat 10, and each mounting ear 9 is provided with a second fastening bolt 8. A second threaded hole 15 for accommodating the second fastening bolt 8 is opened on the inner wall of the telescopic ladder body 1. The mounting ears 9 provide a mounting position for the second fastening bolt 8 on the mounting seat 10, and when the second fastening bolt 8 is screwed into the second threaded hole 15, the mounting seat 10 is fixedly mounted on the inner side of the telescopic ladder body 1 through the mounting ears 9, thereby providing a mounting position for the rotating seat 7.
[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
