DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0024] Please refer to Figures 1-8 The utility model provides a kind of climbing type sound barrier stand column, including stand main body 1, the upper side of stand main body 1 is equipped with slot 2, the inner side of slot 2 is slidably connected to stand 3, the top of stand 3 is fixedly connected with top seat 4, the side of stand 3 is equipped with first jack 6 and second jack 7, and second jack 7 is located below first jack 6, installation slot 8 is equipped on the outside of stand main body 1, positioning mechanism is installed in the inner side of installation slot 8, connecting groove 14 is equipped in the inner side of stand main body 1, and connecting groove 14 is located at the two sides of stand 3, fixed rod 15 is fixedly connected in the inner side of connecting groove 14, ball 16 is rotatably connected on the outside of fixed rod 15, and ball 16 is abutted on the outer surface of stand 3 and is rotatably connected with it.

[0025] The outside of stand main body 1 and top seat 4 is equipped with positioning groove 5, and sound barrier can be installed and positioned by positioning groove 5.

[0026] Positioning mechanism includes fixed plate 9, wedge block 10 and spring 11, fixed plate 9 is fixedly connected to the inner side of installation slot 8, wedge block 10 is slidably connected to the inner side of installation slot 8, and the tail end of wedge block 10 is inserted into the inner side of first jack 6, the bottom of wedge block 10 is equipped with inclined plane, and spring 11 is fixedly connected between wedge block 10 and fixed plate 9.

[0027] The wedge-shaped block 10 is fixedly connected with a pull rod 12, the end of the pull rod 12 protrudes outside the mounting groove 8 through the fixed plate 9, and the end of the pull rod 12 is fixedly connected with a connecting rod 13.

[0028] The connecting grooves 14 are arranged in several groups and vertically.
