[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Please see Figure 1-2 The present invention relates to a scraper for removing the oxide layer from PE pipes, comprising: The skeleton support mechanism 1 is used to extend into the PE pipe from which the oxide layer is to be scraped off and to support the inner wall of the PE pipe. The scraper mechanism 2 is disposed outside the skeleton support mechanism 1, and includes a scraper arm 21, a scraper blade 22 disposed on the scraper arm 21 for scraping off the oxide layer, and a drive member 23 for driving the scraper arm 21 to rotate.

[0019] In use, the skeleton support mechanism 1 is first inserted into the PE pipe. The skeleton support mechanism 1 supports the inside of the PE pipe to ensure the stability of the device. Then, the drive component 23 drives the scraper arm 21 to rotate, and the scraper blade 22 on the scraper arm 21 scrapes off the oxide layer.

[0020] In one embodiment, the skeleton support mechanism 1 includes a fixed rod 11 with external threads, multiple sets of support skeletons 12 disposed on the fixed rod 11, and adjusting nuts 13 threaded on the fixed rod 11 for adjusting the support skeletons 12. This design allows the support skeletons 12 to be adjusted according to the inner diameter of the PE pipe using the adjusting nuts 13, facilitating support of the PE pipe by the support skeletons 12 and achieving device positioning.

[0021] In one embodiment, the fixing rod 11 is provided with a plurality of evenly distributed adjustment grooves 14. The support frame 12 includes two support rods 121 that are cross-connected and rotatably arranged in the adjustment grooves 14. One end of the support rod 121 closer to the adjusting nut 13 is slidably positioned in the adjustment groove 14, while the other end of the support rod 121 further away from the adjusting nut 13 is rotatably positioned in the adjustment groove 14. This design allows the support rod 121 closer to the adjusting nut 13 to slide within the adjustment groove 14 by rotating the adjusting nut 13, thereby cooperating with the rotatably connected support rod 121 to adjust the support range of the support frame 12. This enables the support frame 12 to adapt to PE pipes of different sizes, achieving the positioning of PE pipes of different sizes.

[0022] In one embodiment, a telescopic rod 3 for adjusting the horizontal position of the scraper arm 21 is provided between the fixed rod 11 and the scraper arm 21. The telescopic rod 3 is an electric telescopic rod 3 in the prior art, so its specific structure will not be described in detail here. This design allows the horizontal position of the scraper arm 21 to be adjusted as needed by providing the telescopic rod 3, thereby adjusting the position of the scraper blade 22 and facilitating the scraper blade 22 to scrape different parts of the PE pipe.

[0023] In one embodiment, the scraper arm 21 includes a vertical rod 211 for connection to the frame support mechanism 1 and a horizontal rod 212 disposed at one end of the vertical rod 211 for mounting the scraper blade 22. One end of the telescopic rod 3 is fixedly connected to the fixed rod 11, and the other end of the telescopic rod 3 is rotatably connected to the vertical rod 211. This design, by adding a scraper arm 21 consisting of a vertical rod 211 and a horizontal rod 212, allows the vertical rod 211 to be connected to the telescopic rod 3, and the horizontal rod 212 to mount the scraper blade 22, thus facilitating the scraping operation on the PE pipe.

[0024] Preferably, the scraper 22 includes a mounting base 221 detachably mounted on the crossbar 212 and a blade 222 disposed on the mounting base 221. The mounting base 221 is provided with a mounting plate 223 bolted to the crossbar 212. This design facilitates the replacement of the scraper 22 after the blade 222 wears or is damaged.

[0025] In one embodiment, the vertical rod 211 is provided with a mounting shell 4 for rotatably connecting with the telescopic rod 3. The mounting shell 4 is provided with a driving device 5 for driving the vertical rod 211 to move vertically. This design facilitates rotatable connection with the telescopic rod 3 by providing the mounting shell 4, and allows the vertical rod 211 to move vertically within the mounting shell 4 by providing the driving device 5, thereby adjusting the vertical position of the scraper.

[0026] In one embodiment, the driving device 5 includes a knob 51 passing through the mounting housing 4. A gear and rack transmission structure is provided between the knob 51 and the vertical rod 211. The gear and rack transmission mechanism is a gear and a rack meshing with the gear in the prior art. The specific structure will not be described in detail here. More specifically, a gear is provided on one end of the knob 51 that passes through the mounting housing 4, and a rack meshing with the gear is provided on the vertical rod 211. With this design, by setting the knob 51 and the gear and rack transmission structure, the vertical rod 211 can be moved vertically within the mounting housing 4 by rotating the knob 51, thereby changing the vertical distance between the scraper and the PE pipe.

[0027] In one embodiment, the drive component 23 includes a connecting rod 231 disposed on the side of the mounting housing 4 away from the telescopic rod 3. The connecting rod 231 is used for detachably connecting the output end of a motor. This design allows for detachable connection of a motor, so that after connection, the motor can drive the mounting housing 4 and the scraper arm 21 to rotate, thus achieving electric drive of the scraper 22.

[0028] In one embodiment, the drive member 23 includes a handle 232 disposed on the scraper arm 21. This design allows the scraper arm 21 to be rotated manually by holding the handle 232 during the removal of the oxide layer, thus enabling manual drive of the scraper blade 22.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
