[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A rock wool protective structure for HDPE casing includes a casing body, wherein the outer wall of the casing body is provided with a fireproof mechanism.

[0008] The fireproof mechanism includes an installation strip that is slidably connected to the outer wall of the sleeve body. The outer wall of the installation strip is covered with a fireproof layer. A positioning block is slidably connected inside the installation strip. An adjusting shaft is fixedly connected to the outer wall of the positioning block inside the sleeve body. A spiral spring is fixedly connected to the outer wall of the adjusting shaft near the positioning block.

[0009] As a preferred embodiment of this utility model, the mounting strip, positioning block, and adjusting shaft are all made of ABS plastic. Multiple sets of positioning blocks and spiral springs are provided, and the spiral springs are fixedly connected to the sleeve body.

[0010] As a preferred embodiment of this utility model, the fireproof layer is made of rock wool cloth, the positioning block penetrates the mounting strip and extends into the sleeve body, and the adjustment shaft is connected to the sleeve body by a rotatable connection.

[0011] As a preferred embodiment of this utility model, the adjusting shaft extends through and out of the sleeve body, the mounting strip has a T-shaped structure design, and both the mounting strip and the adjusting shaft are provided with four sets.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, by setting a fireproof mechanism on the casing body, the fireproof layer can be fixedly covered on the outer wall of the casing body by using the installation strip and positioning block in the fireproof mechanism through a fixing structure. This allows the casing body to increase its fire resistance by utilizing the fireproof layer covering the outer wall during use, thus solving the problem that the existing HDPE casing has poor fire resistance and cannot meet the user's requirements.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] For examples, please refer to Figure 1-3 This utility model provides a technical solution:

[0020] A rock wool protective structure for HDPE casing includes a casing body 1, and a fireproof mechanism 2 is provided on the outer wall of the casing body 1.

[0021] The sleeve body 1 is made of polyethylene plastic;

[0022] In this embodiment, reference Figure 2 and Figure 3 The fireproof mechanism 2 includes an installation strip 201 that is slidably connected to the outer wall of the sleeve body 1. The outer wall of the installation strip 201 is covered with a fireproof layer 202. A positioning block 203 is slidably connected inside the installation strip 201. An adjusting shaft 204 is fixedly connected to the outer wall of the positioning block 203 and inside the sleeve body 1. A spiral spring 205 is fixedly connected to the outer wall of the adjusting shaft 204 near the positioning block 203.

[0023] The mounting strip 201, positioning block 203, and adjusting shaft 204 are all made of ABS plastic. Multiple sets of positioning blocks 203 and spiral springs 205 are provided. The spiral springs 205 are fixedly connected to the sleeve body 1. The fireproof layer 202 is made of rock wool cloth. The positioning block 203 penetrates the mounting strip 201 and extends into the sleeve body 1. The adjusting shaft 204 is rotatably connected to the sleeve body 1 and penetrates and extends outside the sleeve body 1. The mounting strip 201 has a T-shaped structure design. Four sets of both the mounting strip 201 and adjusting shaft 204 are provided. When the fireproof layer 202 on the outer wall of the sleeve body 1 is damaged, the adjusting shaft will rotate to adjust the position. Shaft 204, adjusting shaft 204 drives positioning block 203 to rotate. The rotating positioning block 203 will disengage from the mounting strip 201. The positioning block 203 will no longer hold the mounting strip 201, pushing the mounting strip 201. The mounting strip 201 will drive the fireproof layer 202 to detach from the outer wall of the sleeve body 1. Then, the mounting strip 201 on the new fireproof layer 202 will be inserted into the sleeve body 1. The adjusting shaft 204 will be released, and the spiral spring 205 will drive the adjusting shaft 204 to rotate in the opposite direction. The reverse-rotating adjusting shaft 204 will drive the positioning block 203 to re-insert into the mounting strip 201. The positioning block 203 will hold the mounting strip 201, thereby fixing the new fireproof layer 202 to the outer wall of the sleeve body 1.

[0024] The working process of this utility model is as follows: When using the rock wool cloth-coated HDPE sleeve designed in this scheme, the sleeve body is installed on the inclined cable. The fireproof layer 202 on the outer wall of the sleeve body 1 is made of rock wool cloth and has high fire resistance. When the fireproof layer 202 on the outer wall of the sleeve body 1 is damaged, the adjusting shaft 204 is rotated. The adjusting shaft 204 drives the positioning block 203 to rotate. The rotating positioning block 203 will disengage from the mounting strip 201, and the positioning block 203 will no longer lock the mounting strip 201. 1. Push the installation strip 201. The installation strip 201 causes the fireproof layer 202 to detach from the outer wall of the sleeve body 1. Then insert the installation strip 201 on the new fireproof layer 202 into the sleeve body 1. Release the adjusting shaft 204. The spiral spring 205 causes the adjusting shaft 204 to rotate in the opposite direction. The rotating adjusting shaft 204 causes the positioning block 203 to re-insert into the installation strip 201. The positioning block 203 locks the installation strip 201, thereby fixing the new fireproof layer 202 to the outer wall of the sleeve body 1.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
