[0003] The glass circular cutter can cut glass into circular, arc-shaped and other shapes. It is the main operating device for glass cutting. Due to the inconsistent thickness of glass, especially special glass, different depths of cutting are required when cutting it. Traditional cutting devices can only perform cutting of different depths by applying different forces to the entire device using external force. It is impossible to perform cutting of different depths by adjusting the contact depth between the blade and the glass, which limits the diversity and convenience of the device.

[0004] Therefore, we offer a special glass circle cutter. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] Example 1: A special glass circle cutter, such as Figure 1 - Figure 4 As shown, it includes a support rod 1, a rotation adjustment frame 2, a center support column 3, and a support frame 4 installed at the lower end of the support rod 1. A cutting head 6 is rotatably provided in the middle of the support frame 4, and a rotating column 5 is inserted in the middle of the cutting head 6. The rotating column 5 is rotatably provided on both sides of the inner wall of the support frame 4, and the rotating column 5 extends to the inside of the support frame 4. A rotating gear 7 is provided on opposite sides of the rotating column 5, and an L-shaped connecting frame 12 is provided on the outside of the rotating gear 7. A plurality of meshing teeth 13 are provided on the surface of the L-shaped connecting frame 12 close to the rotating gear 7. The rotating gear 7 is meshed with the meshing teeth 13. A V-shaped connecting frame 14 is installed at the horizontal end of the upper end of the L-shaped connecting frame 12, and a rotating guide rod 15 is rotatably connected to both sides of the lower end of the V-shaped connecting frame 14. The lower end of the rotating guide rod 15 is rotatably connected to a guide frame 16, and an inclined guide plate 17 is installed at the end of the guide frame 16 away from the rotating guide rod 15. The two inclined guide plates 17 are symmetrically installed.

[0026] First, the rotating gear 7 is controlled to rotate, and the height of the L-shaped connecting frame 12 is adjusted under the meshing transmission of the meshing teeth 13, so that the height of the V-shaped connecting frame 14 is adjusted synchronously, and under the rotation connection of the rotating guide rod 15 and the support of the guide frame 16, the inclined guide plates 17 on both sides below are moved at the same time, and under the guide limit of the support frame 4, the inclined guide plates 17 on both sides are moved upward at an angle, and correspondingly, the lower end surface of the support frame 4 is gradually moved toward the glass surface, and synchronously, the contact distance between the cutting head 6 and the glass surface is deepened, so as to adjust the device to perform cutting of different depths, so that it can more accurately perform circular cutting on special glasses of different thicknesses, and under the contact between the inclined guide plates 17 on both sides and the glass surface, the running position of the cutting head 6 can be limited so that it is fixed on both sides. The inclined guide plates 17 are arranged between the two sides to improve the accuracy of the contact point when cutting a circle. Secondly, by adjusting the inclined guide plates 17 on both sides to different heights, the two sides of the cutting head 6 are tilted, and the supporting part of the device is slightly adjusted to make the side of the cutting head 6 contact the glass surface, reducing the area of ​​contact with the glass. Under the same pressure, the pressure of the cutting head 6 on the glass can be increased, the cutting strength can be improved, and when the curvature of the outer surface of the cutting head 6 and the side surface are inconsistent, the groove surface cut by the glass can present a certain curvature, thereby improving the various usage of the device. Finally, when the rotating adjustment frame 2 is threadedly connected to the center support column 3, and when the support rod 1 is threadedly connected to the rotating adjustment frame 2, it is convenient to adjust the effective height and radius of the cutting head 6, so that it is convenient to use it in a variety of ranges.

[0027] like Figure 1 - Figure 4 As shown, inclined guide grooves 18 are opened on opposite sides of the inner wall of the support frame 4, and the guide rod in the guide frame 16 is slidably set inside the inclined guide groove 18. The inclined guide plate 17 and the limit plate in the guide frame 16 are respectively located on opposite sides of the inclined guide groove 18.

[0028] The lower half of the outer side of the support frame 4 has a conical structure on both opposite sides, and the inner inclined surface of the inclined guide plate 17 fits in with the conical surface of the support frame 4 .

[0029] Based on the inclined structure of the inclined guide plate 17 adapted to the support frame 4, the direction of the inclined guide plate 17 is guaranteed to be accurate when supporting the support frame 4 and moving and adjusting the inclined guide plate 17, and with the guidance assistance of the inclined guide groove 18, the angle of the inclined guide plate 17 is guaranteed to be accurate and stable when it moves upward.

[0030] like Figure 1 - Figure 4 As shown, a support frame for sliding guide support is inserted into the lower end of the L-shaped connecting frame 12, and a plurality of telescopic components for guiding support are provided on the upper end surface of the V-shaped connecting frame 14.

[0031] With the support frame guiding the L-shaped connecting frame 12 and the telescopic assembly guiding the V-shaped connecting frame 14, the direction of the device is ensured to be accurate and reliable when moving.

[0032] Example 2: A special glass circle cutter, such as Figure 1 - Figure 4 As shown, support shafts are fixedly installed on the opposite end surfaces of the rotating column 5, and the rotating gear 7 is rotatably arranged on the outside of the support shaft, and a rotating connecting frame 8 is installed on the side surface of the rotating gear 7 away from the rotating column 5, and an adjustment bolt 9 is threadedly connected to the middle part of the outer side of the rotating connecting frame 8.

[0033] A limit rod 11 is provided inside the threaded hole in the middle of the outer side of the rotating connecting frame 8 , a guide groove 10 is provided through the adjusting bolt 9 , the adjusting bolt 9 extends into the threaded hole, and the limit rod 11 is slidably provided inside the guide groove 10 .

[0034] The adjusting bolts 9 are threadedly connected to the supporting frame 4 , and the adjusting bolts 9 extend into the interior of the supporting frame 4 . The adjusting bolts 9 are disposed on opposite sides of the supporting frame 4 .

[0035] By rotating the adjusting bolt 9, the support frame 4 and the adjusting bolt 9 are threadedly connected, so that the distance moves while it rotates. Based on the plug-in limit of the guide groove 10 and the limit rod 11, the adjusting bolt 9 can drive the rotating connecting frame 8 to rotate while moving horizontally, so that the rotating gear 7 is transmitted at the same time, thereby ensuring that the rotating gear 7 drives the transmission component on one side to move stably and reliably under the rotation support of the support shaft.

[0036] Working principle: First, rotate the adjusting bolt 9 so that the adjusting bolt 9 can drive the rotating connecting frame 8 to rotate while moving horizontally, so that the rotating gear 7 is transmitted at the same time, and the meshing teeth 13 are engaged with it to adjust the height of the L-shaped connecting frame 12, so that the height of the V-shaped connecting frame 14 is adjusted synchronously, and the inclined guide plates 17 on both sides below are moved at the same time, and under the guide limit of the support frame 4, the inclined guide plates 17 on both sides are moved upward at an angle, correspondingly, the lower end surface of the support frame 4 is gradually moved toward the glass surface, and synchronously, the contact distance between the cutting head 6 and the glass surface is deepened, so as to adjust the device to cut at different depths, so that it can more accurately cut special glasses of different thicknesses into circles.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
