[0028] See also Figures 1 to 6 As shown, a cutting marking device for aluminum tubes includes a placement seat 1. The placement seat 1 is a long strip-shaped plate body, and two supports 2 are fixed on the plate body. The supports 2 are provided with arc-shaped notches for placing pipe fittings. After the two ends of the pipe fittings are placed on the arc-shaped notches, there is a certain distance between the pipe fittings and the placement seat 1. A slide seat 3 is provided on the placement seat 1. The slide seat 3 is located between the two supports 2. A stand 4 is provided at one end of the slide seat 3. The stand 4 can be a door-shaped frame, or a strip plate. The strip plate is perpendicular to the slide seat 3, and a circular notch for passing the pipe fittings is provided on the strip plate. A flip frame 5 is connected to the slide seat 3. The aluminum tube can pass through the flip frame 5 and the stand 4 at the same time. The flip frame 5 includes a "U"-shaped outer frame body 51. An inner ring body 52 is fixed inside the outer frame body 51. The inner ring body 52 is slidably connected to the outer frame body 51, that is, the outer frame body 51 is provided with a flip frame 5. A slideway is provided on the inner side wall of the inner ring body 51, and a slider is fixed on the outer circumferential surface of the inner ring body 52. ​​The slider is adapted in the slideway so that the inner ring body 52 can slide. The slider is set as a square body so that the inner ring body 52 cannot flip independently, that is, the inner ring body 52 and the outer frame body 51 are always located on the same plane. The aluminum tube passes through the inner ring body 52, and a rotating ring 53 is connected to the inner ring body 52. ​​The rotating ring 53 has a cutting component 6. When the rotating ring 53 rotates, a marking line can be drawn on the surface of the aluminum tube by the cutting component 6.

[0029] The specific connection method between the rotating ring 53 and the inner ring body 52 is as follows: an annular groove 54 is provided on the inner ring body 52, and a protruding column 55 is provided on the rotating ring 53. The protruding column 55 is adapted in the annular groove 54, so that the rotating ring 53 can be controlled to rotate, but it will not separate from the inner ring body 52.

[0030] The above-mentioned marking assembly 6 includes a sleeve 61 passing through the rotating ring 53. There are a plurality of sleeves 61, which are distributed in a circular array around the central axis of the rotating ring 53. A marking rod 62 passes through each sleeve 61. The extension line of the marking rod 62 passes through the center of the rotating ring 53. The inner end of the marking rod 62 is sharp, and a pressure cap 63 is fixed to the outer end of the marking rod 62. In the normal state, the inner end of the marking rod 62 is aligned with the center of the rotating ring 53. When the aluminum tube passes through the rotating ring 53, the inner end of the marking rod 62 is against the surface of the aluminum tube. At this time, the rotating ring 53 is controlled to rotate, and a marking line can be drawn on the aluminum tube through the inner end of the marking rod 62; in order to better control the marking rod 62, a tension reset spring 64 is sleeved on the marking rod 62, and the two ends of the tension reset spring 64 are respectively fixed to the pressure cap 63 and the sleeve 61, so that when marking the aluminum tube, there is no need to manually apply pressure to the marking rod 62.

[0031] In order to mark the inclination angle of the incision marking line drawn on the aluminum tube, a semicircular display disk 7 is fixed to the upper end of the stand 4, and a scale line 8 for displaying a specific angle is provided on the display disk 7. The display disk 7 is located directly above the pipe fitting, and the flip frame 5 is slidably connected to the slide seat 3. A pointer 9 is fixed on the flip frame 5. The pointer 9 is fixed on the outer frame body 51, and the extension line of the pointer 9 passes through the center of the inner ring body 52. ​​After the flip frame 5 moves, the pointer 9 is flipped and can correspond to a certain scale line 8, thereby displaying the flip angle of the flip frame 5. The flip angle range of the flip frame 5 is 45° to 90°.

[0032] The above-mentioned pointer 9 is connected to the display panel 7 through the central axis 10. Specifically, the central axis 10 is fixed at the center of the display panel 7, and the pointer 9 is provided with a waist-shaped strip 91 extending along its length direction. The central axis 10 passes through the waist-shaped strip 91. The length of the pointer 9 is slightly larger than the radius of the display panel 7. At the same time, the pointer 9 is provided with a linear opening 92 extending along its length direction for easy reading. The linear opening 92 is located on the extension line of the waist-shaped strip 91. When the pointer 9 is turned over with the central axis 10 as the base point, the scale line 8 on the display panel 7 can be observed through the linear opening 92, so as to determine the turning angle. When the turning frame 5 is in a vertical state, the pointer 9 is also in a vertical state. At this time, the pointer 9 is aligned with the 90° scale line 8 on the display panel 7. In addition, the pointer 9 can be set as a strip plate, and the strip plate is provided with a notch extending from one end to the other end, and the display panel 7 is located in the notch.

[0033] After the lower end of the turning frame 5 moves horizontally, the positioning needle 9 moves in the waist-shaped strip 91 to adjust the turning angle of the turning frame 5. At this time, the turning angle of the turning frame 5 can be observed through the positioning needle 9, and the rotating ring 53 can be controlled to rotate, thereby marking a mark line on the aluminum tube to facilitate subsequent accurate cutting.

[0034] See also Figures 7 to 9 As shown, the lower end of the above-mentioned flip frame 5 is hinged on the slide plate 11, and the slide plate 11 is a long strip plate. The slide plate 11 is located on the slide seat 3, and the width of the slide plate 11 is equal to the width of the slide seat 3. The side of the slide seat 3 is provided with a slide groove 12, and the cross section of the slide groove 12 is "T"-shaped. Each slide groove 12 is adapted to be equipped with a locking component, and the locking component is a "T"-shaped structure. The locking component is connected to a limiting plate 14, and the limiting plate 14 is fixedly connected to the slide plate 11. There are two limiting plates 14 and the two limiting plates 14 are arranged in parallel. The slide seat 3 is located between the two limiting plates 14. When the slide plate 11 moves, the locking component moves in the slide groove 12, and the flip frame 5 can be flipped based on the hinge point with the slide plate 11, and the flip frame 5 forms a flipped state;

[0035] The locking component includes at least two structures, as follows:

[0036] 1. The locking assembly includes a locking rod 131 and a sliding plate 132. The sliding plate 132 is fixed to one end of the locking rod 131. The other end of the locking rod 131 passes through the limiting plate 14. The limiting plate 14 is provided with a circular hole corresponding to the limiting rod. The sliding plate 132 is located in the slide groove 12. A locking nut 133 is screwed on the locking rod 131. The limiting plate 14 is located between the locking nut 133 and the slide seat 3. After tightening the locking nut 133, the slide plate 11 can be locked. At this time, the flip frame 5 is locked in a tilted state;

[0037] 2. The locking assembly can also include a locking sleeve 134, which passes through the limit plate 14 and is fixedly connected to the limit plate 14. The inner wall of the locking sleeve 134 has a thread. One end of the locking sleeve 134 is located in the slide groove 12, and the other end of the locking sleeve 134 is screwed with a locking bolt 135. After the locking bolt 135 is screwed in, the end of the locking bolt 135 rests on the bottom surface of the slide groove 12, and the slide plate 11 is also locked at this time.

[0038] When the above-mentioned aluminum pipe cutting marking device is working, the aluminum pipe is first passed through the notches on the stand 4 and the flip frame 5 and placed in the arc-shaped notch on the support platform 2, and then the flip frame 5 is adjusted, and the pointer moves accordingly. When the preset angle of the incision to be cut on the pipe is reached, that is, when the corresponding angle displayed on the pointer and the display disk 7 is the preset value, the flip frame 5 is locked in a fixed position. At this time, the rotating ring 53 is controlled to rotate, and the marking rod 62 passing through the rotating ring 53 will draw a marking line on the aluminum pipe, which is convenient for subsequent accurate cutting.

[0039] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
