[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] See also Figure 1-6 The utility model provides a technical solution: an easily adjustable anchor bolt, comprising a column 1, an external thread 2 is provided on the upper surface of the column 1, and adjusting rods 3 are slidably inserted on both sides of the bottom of the column 1, and a hook 4 is integrally formed at the bottom of the adjusting rod 3; the adjusting rod 3 and the hook 4 are integrally formed, and the hook 4 can be buried in concrete and connected with the concrete to make a prefabricated part. Part of the column 1 is used to connect the mechanical components installed on the concrete prefabricated part, and the external thread 2 is also provided to assist in the connection with the mechanical components. The hook 4 is buried inside the concrete prefabricated part, which can improve the firmness of the connection between the anchor bolt and the concrete prefabricated part, thereby improving the stability of the mechanical components during connection and installation.

[0028] Furthermore, both sides of the bottom of the column 1 are provided with sliding grooves 5, and the adjusting rod 3 is slidably inserted in the sliding grooves 5. The bottom of both sides of the column 1 is provided with grooves, and the limiting components are arranged in the grooves. By providing the sliding grooves 5, the sliding grooves 5 are used to accommodate the adjusting rod 3.

[0029] Specifically, the adjusting rod 3 can slide inside the sliding groove 5, thereby achieving the advantage of adjusting the height of the adjusting rod 3. The change in the position of the adjusting rod 3 can also drive the position of the hook 4 to adjust, thereby achieving the purpose of adjusting the distance between the column 1 and the concrete prefabricated part, and can be suitable for installing and connecting mechanical components of different types and heights. By setting the groove, an installation space is provided for the installation of the limited component, and the compactness of the anchor bolt structure is improved.

[0030] It is worth noting that: the bottom of both sides of the column 1 is equipped with a limiting component for limiting the height of the adjustment rod 3; the limiting component includes a screw rod 6, one end of which is threadedly connected to the inside of the groove, and one end of the screw rod 6 extends to the inside of the sliding groove 5. The surface of the adjustment rod 3 is equidistantly provided with positioning screw holes 7 adapted to the screw rod 6, and one end of the screw rod 6 is threadedly connected to the inside of the positioning screw hole 7. By setting the positioning screw holes 7, the number of positioning screw holes 7 is set in multiple groups. After the screw rod 6 enters the inside of the positioning screw hole 7, the position of the adjustment rod 3 can be limited, so that it is not easy to move. By connecting the screw rod 6 with the positioning screw holes 7 at different positions, the purpose of conveniently adjusting and fixing the screw rod 6 at different heights is achieved.

[0031] Furthermore, a protective component for protecting the limiting component is sleeved outside the column 1 and located outside the limiting component, and the protective component includes a protective ring 8, which is slidably sleeved on the surface of the column 1, and a limiting ring 9 is installed on the surface of the column 1 and located at the bottom of the protective ring 8, and the bottom of the protective ring 8 is in contact with the top of the limiting ring 9. By providing the limiting ring 9, the protective ring 8 can be supported so that the protective ring 8 will not easily deviate.

[0032] Specifically, a protective shell 10 is installed at the bottom of the protective ring 8, and a sealing ring 11 is installed at the bottom of the protective shell 10, and the inner side of the sealing ring 11 is slidably fitted with the surface of the column 1. By providing the protective ring 8 and the sealing ring 11, the screw 6 originally exposed outside the column 1 can be covered, so that the connection between the screw 6 and the column 1 can be protected, reducing dust pollution and rust, so that the screw 6 is not easy to slip and lock during installation and removal, which brings convenience to the later installation and removal.

[0033] In addition, a sealing ring 11 is provided to seal the bottom of the protective shell 10 , thereby achieving the purpose of all-round protection of the screw 6 .
