[0033] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0034] In a first aspect, an embodiment of the present application discloses a pipe cutting machine protective cover.

[0035] Embodiment 1: Reference Figure 1 and Figure 2 A protective cover for a pipe cutting machine includes a cover body 1, which includes a front plate 2, a back plate 3 and a top plate 4. The front plate 2 and the back plate 3 are arranged parallel to each other, the top plate 4 is located at the upper end of the back plate 3 and is slidably connected to the back plate 3, and the front plate 2 is movably connected to the top plate 4; if a problem occurs in a running machine tool, the front plate 2 is operated to move and open the front plate 2, and then the top plate 4 is operated to slide in a direction close to the back plate 3. At this time, the top plate 4 drives the front plate 2 to move in a direction close to the back plate 3, and the cover body 1 is fully opened, so that the staff can easily repair the machine tool.

[0036] Reference Figure 2and Figure 3 The front plate 2 is vertically slidably connected to the top plate 4. The end of the top plate 4 away from the back plate 3 is hinged with two cylinders 42. The two cylinders 42 are respectively located at the two ends of the width direction of the top plate 4, and the piston rods of the two cylinders 42 are hinged to the front plate 2. When the cover body 1 is opened, the piston rod of the cylinder 42 is firstly operated to retract, thereby driving the front plate 2 to move up. At this time, the front plate 2 moves away from the machine tool.

[0037] Reference Figure 3 and Figure 4 Two limit blocks 43 are provided at the lower end of the top plate 4, and the two limit blocks 43 are respectively located at the two ends of the top plate 4 in the length and width directions, and the two limit blocks 43 are located at the end away from the back plate 3. Two slide rails 21 adapted to the limit blocks 43 are arranged on the side of the front plate 2 close to the top plate 4. The slide rails 21 correspond to the limit blocks 43 one by one, and each limit block 43 is sleeved on the outside of the corresponding slide rail 21; when the cylinder 42 drives the front plate 2 to slide, the slide rail 21 moves with the sliding of the front plate 2, and the limit block 43 limits the moving direction of the slide rail 21, thereby improving the stability of the front plate 2 when sliding, and the convenience of opening the protective cover is relatively high.

[0038] Reference Figure 2 and Figure 3 The lower end of the back plate 3 is detachably connected to the upper surface of the workbench, and two support frames 31 are provided on the upper end of the back plate 3, and the two support frames 31 are fixedly connected to the back plate 3, and the two support frames 31 are respectively located at the two ends in the width direction of the back plate 3, and the two support frames 31 are perpendicular to the back plate 3, and the top plate 4 is slidably connected to the two support frames 31; the staff can push the top plate 4 to move the top plate 4 in the direction close to the back plate 3, and then drive the front plate 2 to move in the direction close to the back plate 3. During the movement of the top plate 4, due to the long length of the support frames 31, when the top plate 4 slides on the support frames 31, the contact area between the top plate 4 and the support frames 31 is large, the sliding of the top plate 4 is relatively stable, and the movement of the front plate 2 is also relatively stable, thereby improving the stability of opening the cover body 1.

[0039] Reference Figure 2 and Figure 5, the two support frames 31 extend in the direction close to the front plate 2, and the upper ends of the two support frames 31 are provided with limit blocks 32, and the lower end of the top plate 4 is provided with two slide rails 41 adapted to the limit blocks 32, and the two slide rails 41 are respectively located on both sides of the length direction of the top plate 4, and the slide rails 41 correspond to the limit blocks 32 one by one, and each limit block 32 is sleeved on the outside of the corresponding slide rail 41; when the top plate 4 slides, the slide rail 41 moves with the sliding of the top plate 4, and the slide rail 41 is limited by the limit block 32, thereby limiting the sliding direction of the top plate 4, thereby improving the stability of the top plate 4 when sliding; the cover body 1 is opened, because the front plate 2 and the top plate 4 are far away from the machine tool at this time, the staff can easily inspect and repair the machine tool.
