Detailed Embodiment

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0029] Please refer to Figure 1 Figures X to X for a description of a rotating device for an insertion - type skin scraping device provided by the present utility model. The rotating device for the insertion - type skin scraping device is arranged on the box body 1 of the skin scraping device. The front side of the box body 1 has a receiving cavity 11, and the rear side is provided with a rotating handle 12. Inside the receiving cavity 11, there is a clamping device 13 for clamping a plastic pipe. The rear side of the box body 1 has a number of continuous through - slots 14. The number of continuous through - slots 14 is arranged along the height direction and is interconnected. The inner peripheral wall of each continuous channel has an internal thread. The rotating device includes a rotating shaft 2 and a connecting component 3. The outer peripheral wall of the rotating shaft 2 has an external thread. One end of the rotating shaft 2 is connected to the rotating handle 12, and the other end is in threaded cooperation with one of the continuous through - slots 14. One end of the connecting component 3 is used to connect to the rotating handle 12, and the other end is used to connect to the box body 1. Among them, after the rotating shaft 2 is in threaded cooperation with one of the continuous through - slots 14, the connecting component 3 can connect the rotating handle 12 and the box body 1. Each continuous through - slot 14 corresponds to a rotating shaft 2 of a plastic pipe of a certain pipe diameter. The clamping device 13 includes a support seat 131, a support roller 132 rotatably arranged on the support seat 131, and a screw 133. The screw 133 is in threaded cooperation with the bottom of the box body, and one end of the screw 133 passes through the box body 1. The screw 133 is rotatably matched with the support seat 131, and the position of the screw 133 and the support seat 131 is relatively fixed. By rotating the screw 133, the support seat 131 can move upward, so that the support roller 132 cooperates with the cutter at the top of the receiving cavity to clamp the plastic pipe. The cutter at the top of the receiving cavity 11 is a hob, and the hob is rotatably matched with the box body. A guide rod 134 is fixedly arranged at the bottom of the support seat 131. One end of the guide rod 134 passes through the bottom of the box body, and the guide rod 134 is slidably matched with the box body.

[0030] For the rotating device for the insertion - type skin scraping device provided by the present utility model, compared with the prior art, the rotating shaft 2 and the rotating handle 12 are coaxially arranged, and the rotating shaft 2 is fixed on the rotating handle 12. When it is necessary to scrape the oxide skin of plastic pipes with different pipe diameters, the plastic pipe is clamped in the receiving cavity 11 by the clamping device 13. Then, the rotating shaft 2 is in threaded cooperation with the corresponding continuous through - slot 14, which can make the rotating shaft 2 and the plastic pipe coaxially arranged, reducing the eccentricity between the rotating handle 12 and the plastic pipe. When the operator rotates the rotating handle 12, the situation that the rotating handle 12 radially deviates along the plastic pipe can be reduced.

[0031] In some embodiments, as Figure 1 shown, a number of connecting holes 15 are provided on the box body 1 on one side of the continuous through - slots 14. The number of connecting holes 15 is arranged along the height direction. The rotating handle 12 has a through - hole for aligning with one of the connecting holes 15. The connecting component 3 includes a connecting shaft (not shown in the figure) inserted and matched with the through - hole on the rotating handle 12. The other end of the connecting shaft can be inserted and matched with one of the connecting holes 15 to limit the position between the rotating handle 12 and the box body 1.

[0032] It should be noted that after the connecting through groove on the rotating shaft 2 and the box body 1 are in threaded fit, there is no need to tighten the rotating shaft 2, as long as the rotating shaft 2 does not fall off the box body 1; that is, the length of the external thread on the rotating shaft 2 is greater than the thickness of the continuous through groove 14 on the side wall of the box body 1. After the rotating shaft 2 is screwed onto the box body 1, not all of the external thread on the outside of the rotating shaft 2 needs to be screwed into the continuous through groove 14. After the rotating shaft 2 is connected to the box body 1, rotate the rotating handle 12 to the position where the through hole is aligned with one of the connecting holes 15, and then insert and cooperate with the through hole and the connecting hole 15 through the connecting shaft, which can play a role in circumferentially limiting the rotating handle 12; when the operator rotates the rotating handle 12, the box body 1 can rotate together with the rotating handle 12.

[0033] In some embodiments, as Figure 1 shown, several connecting holes 15 are provided on one side of the continuous through groove 14 on the box body 1, and the several connecting holes 15 are arranged in the height direction; the connecting member 3 includes a limiting disk 31, the limiting disk 31 is key-connected to the rotating shaft 2 and is slidably matched with the rotating shaft 2; the limiting disk 31 has a protrusion 32 for inserting and cooperating with one of the connecting holes 15.

[0034] It should be noted that after the rotating shaft 2 is connected to the continuous through groove 14 in place, the total thickness of the limiting disk 31 and the protrusion 32 is less than the distance between the end of the rotating handle 12 and the box body 1. Therefore, during the process of screwing the rotating shaft 2 into the continuous through groove 14, the limiting disk 31 will not interfere. After the rotating shaft 2 is connected in place, the protrusion 32 on the limiting disk 31 faces the connecting hole 15. By sliding the limiting disk 31 along the axial direction, the protrusion 32 can be inserted and cooperated with the connecting hole 15, thereby circumferentially limiting the rotating handle 12; when the operator rotates the handle, the box body 1 rotates together with the handle.

[0035] In some embodiments, as Figure 1 shown, when the protrusion 32 is inserted and cooperated with the connecting hole 15, one side of the limiting disk 31 contacts the outside of the box body 1; a contact member 33 for abutting against the rotating handle 12 is provided on the other side of the limiting disk 31; the contact member 33 includes a contact plate, one end of the contact plate is rotatably arranged on the limiting disk 31, and the other end of the contact plate is used to tightly abut against the rotating handle 12 to keep the protrusion 32 in the inserted state; a placement groove 311 is formed on the outer peripheral wall of the limiting disk 31, and one end of the contact plate is rotatably arranged in the placement groove 311; wherein, when the rotating shaft 2 is in threaded fit with the continuous through groove 14, the other side of the limiting disk 31 contacts the rotating handle 12, and the other end of the contact plate rotates away from the rotating handle 12.

[0036] It should be noted that when the abutting plate abuts against the limiting disk 31 and the rotating handle 12, the axis of the abutting plate is parallel to the axis of the rotating handle 12; when replacing the position of the rotating shaft 2, the abutting plate needs to be rotated away from the abutting position, that is, the abutting plate is rotated outward, and then the limiting disk 31 is slid backward. After the protrusion 32 is separated from the connecting hole 15, the rotating shaft 2 is rotated in the reverse direction, and the rotating shaft 2 can be screwed out from the box body 1. By arranging the abutting plate on the limiting disk 31, when the protrusion 32 is inserted and matched with the connecting hole 15, the abutting plate plays a role in tightly abutting the limiting disk 31 and the rotating handle 12. During the process of rotating the rotating handle 12, the axial sliding of the limiting disk 31 is reduced, so that the protrusion 32 is always in a state of being inserted into the connecting hole 15, ensuring the stability during the rotation process.

[0037] In some embodiments, as Figure 1 shown, the other end of the abutting plate has an inclined surface 331, and a buffer pad (not shown in the figure) is connected to the other end of the abutting plate; wherein, when the abutting plate rotates to the position abutting against the rotating handle 12, the inclined surface 331 side of the abutting plate contacts the rotating handle 12 first; when the abutting plate abuts against the rotating handle 12, the buffer pad is located between the abutting plate and the rotating handle 12, and the buffer pad undergoes elastic deformation.

[0038] It should be noted that by arranging the inclined surface 331 and the buffer pad on the abutting plate, on the one hand, it is convenient to press the abutting plate down to a position parallel to the axis of the rotating handle 12. At this time, the buffer pad undergoes elastic deformation and tightly abuts the rotating handle 12, enabling the limiting disk 31 to be stably in the inserted position.

[0039] In some embodiments, as Figure 1 shown, connection holes 15 are provided on both sides of the continuous through groove 14, and there are also two protrusions 32 on the limiting disk 31. The two protrusions 32 are respectively inserted and matched with the connection holes 15 corresponding to both sides of the continuous through groove 14.

[0040] It should be noted that by arranging two protrusions 32 on the limiting disk 31 and connection holes 15 on both sides of the continuous through groove 14, the two protrusions 32 can be inserted and matched with the connection holes 15 on the corresponding sides of the continuous through groove 14, thereby improving the connection strength between the rotating handle 12 and the box body 1.

[0041] In some embodiments, as Figure 1 shown, the rotating handle 12 has an extension rod 16, and the axial direction of the extension rod 16 is parallel to the axial direction of the rotating shaft 2; the extension rod 16 is located at the edge position of the rotating handle 12.

[0042] It should be noted that by arranging the extension rod 16 on the rotating handle 12 and arranging the extension rod 16 at the edge position of the rotating handle 12, it is convenient for the operator to rotate the rotating handle 12 with one hand.

[0043] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
