Description

Technical Field

[0001] This utility model relates to a glass cutting device, and more particularly to a portable tempered glass cutting device. Background Technology

[0002] Tempered glass is a type of glass that undergoes a special heat treatment process, forming a compressive stress layer on its surface. This significantly improves its mechanical strength and resistance to thermal shock. When tempered glass breaks, it forms unique fragments, reducing the risk of injury to the human body. Therefore, it is widely used in building doors and windows, automotive glass, furniture glass, and other fields.

[0003] Traditionally, tempered glass cutting involves construction workers using glass cutters to cut the glass directly. However, this method has many drawbacks. The cutting effect is easily affected by factors such as the worker's technique, force, and experience, resulting in poor cutting quality. Furthermore, the cutting line cannot be guaranteed to be straight. The raw material is not protected during the cutting process, leading to significant damage and waste. On the other hand, large glass cutting equipment with good cutting results is inconvenient to carry and cannot meet the needs of some scenarios that require flexible operation.

[0004] Therefore, there is a need to design an easy-to-carry tempered glass cutting device. Utility Model Content

[0005] In order to overcome the shortcomings of common tempered glass cutting devices being large and difficult to store, the technical problem of this utility model is to provide an easy-to-carry tempered glass cutting device.

[0006] The technical implementation scheme of this utility model is as follows: an easy-to-carry tempered glass cutting device, including a rotating shaft, a ruler, a protractor and a guide rail. The ruler is rotatably connected to the middle of the rotating shaft, and the guide rail is rotatably connected to the rotating shaft at the lower part of the ruler. The protractor is fixedly connected to the bottom of the rotating shaft. It also includes a clamping block, a pressing element and a cutting mechanism. The clamping block is slidably connected inside the guide rail, and the pressing element is threadedly connected to the middle of the clamping block. The ruler is provided with a cutting mechanism for cutting tempered glass.

[0007] More preferably, the clamping block is provided with small protrusions to facilitate user movement, and a layer of rubber pad is laid at the C-shaped clamping opening of the clamping block.

[0008] More preferably, the cutting mechanism includes a sliding member, a sliding column, an elastic element, a knob, an extrusion member, and a cutting blade. The sliding member is slidably connected to the rear side of the ruler. Two sliding columns are fixedly connected to the top two sides of the sliding member. A knob is threadedly connected to the left and right sides of the sliding member. An extrusion member is slidably connected to the middle of the sliding member. An elastic element is wound around each sliding column. Each elastic element is fixedly connected to the sliding member and the extrusion member respectively. A cutting blade is snapped into the bottom of the extrusion member.

[0009] More preferably, the cutting blade is made of diamond and is removable and replaceable.

[0010] More preferably, it also includes a pressure rod, a piston, and a suction cup.

[0021] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] Example: A portable tempered glass cutting device, such as Figures 1-5 As shown, it includes a rotating shaft 1, a ruler 2, a protractor 3, a guide rail 4, a clamping block 12, a pressing member 13, and a cutting mechanism. The ruler 2 is rotatably connected to the middle of the rotating shaft 1. The guide rail 4 is rotatably connected to the rotating shaft 1 at the lower part of the ruler 2. The protractor 3 is fixedly connected to the rotating shaft 1 at the lower part of the guide rail 4. The clamping block 12 is slidably connected inside the guide rail 4. The clamping block 12 is provided with small protrusions for easy movement by the user. A rubber pad is laid at the C-shaped clamping opening of the clamping block 12. The pressing member 13 is threadedly connected to the middle of the clamping block 12. The ruler 2 is provided with a cutting mechanism for cutting tempered glass.

[0023] according to Figure 1 and Figure 2 It also includes a pressure rod 5, a piston 6 and a suction cup 7. The pressure rod 5 is slidably connected in the rotating shaft 1. The piston 6 is glued to the bottom of the pressure rod 5 and is made of rubber, which can effectively ensure the airtightness of the device. The suction cup 7 is fixed to the bottom of the rotating shaft 1 and has several air inlets.

[0024] When using this device, the operator can first place the glass on a horizontal table. To prevent the device from shaking, the clamping block 12 can be first secured to one side of the glass. Then, the pressing member 13 is rotated clockwise to press against the glass plate, thereby preventing movement during the glass cutting process. This method can also be applied to glass plates of different thicknesses. The rubber pad on the pressing member 13 provides protection, preventing the glass from being scratched by pressure. The position of the clamping block 12 in the guide rail 4 can be adjusted according to the required cutting position and length of the glass plate, thus accommodating glass plates of different lengths.

[0025] After adjusting the position of the clamping block 12, the user can use the suction cup 7 to fix the device to the glass surface, pull the pressure rod 5 upward, and the piston 6 moves upward in the rotating shaft 1 to suck out the air in the suction cup 7, so that the suction cup 7 is tightly attached to the glass, further fixing the device to prevent movement and ensuring the accuracy and safety of cutting.

[0026] according to Figure 3 and Figure 4As shown, the cutting mechanism includes a sliding member 8, a sliding column 801, an elastic member 802, a knob 9, an extrusion member 10, and a cutting blade 11. The sliding member 8 is slidably connected to the rear side of the ruler 2. Two sliding columns 801 are symmetrically welded to the top left and right sides of the sliding member 8. The knob 9 is symmetrically threaded to the bottom left and right sides of the sliding member 8. The extrusion member 10 is slidably connected to the middle of the sliding member 8. An elastic member 802 is wound around each sliding column 801. Each elastic member 802 is fixed to the sliding member 8 and the extrusion member 10 respectively. The cutting blade 11 is snapped into the bottom of the extrusion member 10. The cutting blade 11 is made of diamond and can be removed and replaced.

[0027] Subsequently, using the protractor 3, the angle between the ruler 2 and the rotating shaft 1 is adjusted to the required value. After adjusting the angle of the ruler 2, the pressing member 10 is pressed down. The pressing member 10 moves downward along the sliding column 801, compressing the elastic member 802, which in turn causes the cutting blade 11 to contact the glass surface. At the same time, the pressing member 10 is pulled vertically along the slide rail on the ruler 2, thereby moving the sliding member 8 along with it, so that the cutting blade 11 contacts the glass surface and cuts the glass. After cutting is completed, the pressing member 10 is released, the elastic member 802 is no longer compressed, and the pressing member 10 and the cutting blade 11 return to their original positions. For curved or circular cuts, rotate knob 9 inwards to clamp the ruler 2, then press down on the pressing member 10 again to bring the cutting blade 11 into contact with the glass surface. The natural diamond material of the cutting blade 11 will then cut the glass. To change the diameter of the cut arc, rotate knob 9 to both sides to de-clamp the ruler 2. Then adjust the position of the sliding member 8 on the ruler 2 to the desired position, and finally tighten knob 9 inwards to clamp the ruler 2. This method allows the cutting blade 11 to make cuts of different shapes and ensures a smooth cutting process.

[0028] After the glass is cut, the user can twist the clamping member 13 counterclockwise to move it upwards away from the glass plate, and finally remove the glass plate. The device can also be folded by rotating the ruler 2, reducing its overall size for easy carrying to different occasions.

[0029] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
