[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model 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 of 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 belong to the scope of protection of the present utility model.

[0023] Please refer to Figures 1-5As shown in the figure, the utility model provides a reinforced steel pipe protection cap, which includes a protection shell 1 and a protection ring 2. The protection ring 2 is arranged inside the protection shell 1, and the lower part inside the protection shell 1 is threadedly connected to the outside of the lower part of the protection ring 2. An insertion block member 3 is arranged above the inner wall of the protection shell 1, and the insertion block member 3 is inserted into the upper part inside the protection ring 2. The head of the steel pipe is inserted into the protection ring 2.

[0024] In this embodiment, an internal groove 102 is arranged inside the protection shell 1, and a plurality of insertion block members 3 are fixedly connected to the upper part of the inner wall of the internal groove 102, and the plurality of insertion block members 3 are equally divided into a circle on the upper part of the inner wall of the internal groove 102.

[0025] Furthermore, an internal thread part 101 is arranged below the inner wall of the internal groove 102, and there is a distance between the upper part of the internal thread part 101 and the lower part of the insertion block member 3.

[0026] Among them, an internal thread part 101 and an external thread part 201 are respectively arranged inside the protection shell 1 and outside the protection ring 2 and are engaged with each other, so that the protection shell 1 and the protection ring 2 form an integral protection cap, and the height of the protection ring 2 inside the protection shell 1 can be adjusted by threads.

[0027] Furthermore, the protection ring 2 is inserted and rotatably connected inside the internal groove 102, and an external thread part 201 is arranged on the outer wall of the lower part of the protection ring 2.

[0028] Furthermore, the external thread part 201 is engaged with the internal thread part 101.

[0029] Furthermore, a jack part 4 is arranged above the protection ring 2, and the insertion block member 3 is inserted and slidably connected inside the jack part 4.

[0030] The insertion block member 3 is inserted into the jack part 4 of the protection ring 2, so that the insertion block member 3 fits against the outer wall of the steel pipe, and the insertion block member 3 and the inner wall of the protection ring 2 jointly press against the outer wall of the steel pipe.

[0031] The head of the steel pipe is inserted through a through hole part 202 arranged inside the protection ring 2.

[0032] Furthermore, a rough surface part 301 is arranged on the inner side of the insertion block member 3, and the rough surface part 301 is in close contact with the outer wall of the steel pipe.

[0033] After the inner side of the insertion block member 3 fits against the outer wall of the steel pipe, the rough surface part 301 will increase the fastening of the entire protection cap to the steel pipe.

[0034] Working principle:

[0035] An insert piece 3 is provided above the inner wall of the protective shell 1, and a socket portion 4 is provided above the protective ring 2. When the protective ring 2 is inserted into the protective shell 1, the insert piece 3 needs to be inserted into the socket portion 4 first, so that the inner side of the insert piece 3 is consistent with the inner wall of the protective ring 2, and the protective ring 2 is inserted into the protective shell 1, and the internal threaded portion 101 provided at the lower part of the inner wall of the protective shell 1 is engaged with the external threaded portion 201 provided at the lower part of the outer wall of the protective ring 2, so that the protective ring 2 can be slightly adjusted up and down inside the protective shell 1. After the head of the steel pipe is inserted into the protective ring 2 and deformed for a long time, the protective shell 1 can be rotated in this way. Since the socket portion 4 will support the outer side of the insert piece 3, the rough surface portion 301 of the insert piece 3 presses the outer wall of the steel pipe, so that the entire protective cap is always pressed against the head of the steel pipe.
