Description

Technical Field

[0001] This utility model relates to the field of glass cutting technology, specifically to an adjustable-angle glass cutting head. Background Technology

[0002] Glass is an amorphous solid material, usually transparent or translucent, formed by the cooling and solidification of molten silicate. It is transparent, allowing visible light to pass through, with a light transmittance of over 90%. It is hard but brittle, with a Mohs hardness of approximately 5-7, but lacks ductility and is easily broken. It is chemically inert, resistant to acid and alkali corrosion, and has poor thermal stability. Ordinary glass is prone to cracking when subjected to sudden cooling or heating, but tempered glass or borosilicate glass can improve this. An adjustable-angle glass cutting head is commonly used in the glass processing industry to adapt to different cutting needs.

[0003] The existing glass cutting head requires the user to first hold the handle, then use the cutting blade at the end of the cutting head to make marks on the glass surface. After making the desired marks, the user then uses the tapping head to tap the glass.

[0004] Existing glass cutting heads of this type have the following problems: when using a glass cutting head, the cutting head is fixed, and different cutting heads need to be replaced for different cutting scenarios, which cannot adapt to different cutting scenarios and is inconvenient to use. Therefore, we propose an adjustable-angle glass cutting head. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide an adjustable glass cutting head. When using the glass cutting head, the angle of the cutting head can be adjusted. Different cutting scenarios do not require different cutting heads. It can adapt to different cutting scenarios, is easy to use, and can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adjustable glass cutting head, comprising a support cylinder, a connecting block at the front end of the support cylinder, a cutting head rotatably connected to the front end of the connecting block via a rotating shaft, a cutting blade rotatably connected to the front end of the cutting head via a pin, and an adjustment mechanism;

[0007] Adjustment mechanism: It includes bevel gear one, bevel gear two, rotating shaft bevel gear three, cylinder, rotating column, and bevel gear four. The rear wall of the support cylinder is rotatably connected to the rotating shaft. Bevel gear two is fixedly sleeved on the outer wall of the front end of the rotating shaft. Bevel gear one is fixedly sleeved on the outer wall of the middle part of the rotating shaft. Bevel gear one and bevel gear two are meshed and connected. A cylinder is provided on the rear side of the outer arc surface of the support cylinder. A rotating column is rotatably connected to the top wall of the cylinder. Bevel gear four is fixedly sleeved on the outer wall of the lower end of the rotating column. Bevel gear three is fixedly sleeved on the outer wall of the rear end of the rotating shaft. Bevel gear three and bevel gear four are meshed and connected. When using the glass cutting head, the angle of the cutting head can be adjusted. Different cutting scenarios do not require different cutting heads, which can adapt to different cutting scenarios and is convenient to use.

[0008] Furthermore, the adjustment mechanism also includes an adjustment wheel, which is fixedly connected to the upper end of the rotating column for easy adjustment.

[0009] Furthermore, the adjustment mechanism also includes a locking assembly, which includes an adjustment platform, a slider, a connecting rod, and connecting holes. The outer arc surface of the cylinder is provided with an adjustment platform, and a slider is slidably connected inside the adjustment platform. A connecting rod is fixedly connected to the upper end of the slider. The upper edge of the adjustment wheel is provided with evenly distributed connecting holes. The connecting rod is installed in conjunction with the adjacent connecting holes to achieve locking.

[0010] Furthermore, the locking assembly also includes a telescopic rod and a spring. The telescopic rod is fixedly connected between the bottom wall of the adjusting platform and the lower end of the slider. A spring is sleeved on the outside of the telescopic rod to facilitate rebound.

[0011] Furthermore, the locking assembly also includes an L-shaped groove and a lever. The left end of the adjustment platform is provided with an L-shaped groove, and the left end of the slider is slidably connected to a lever. The outer surface of the lever is slidably connected to the inner wall of the L-shaped groove for easy adjustment.

[0012] Furthermore, the rear end of the support cylinder is provided with a handle, and the rear end of the handle is provided with a striking head for easy striking.

[0013] Furthermore, the striking head is a rubber striking head, which helps to protect the glass surface.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This adjustable-angle glass cutting head has the following advantages:

[0015] By moving the lever downwards and then forwards along the L-shaped groove, the lever is locked. This causes the sliding block to disengage the insertion rod from the insertion hole. Simultaneously, the sliding block compresses the telescopic rod and the spring, thus disengaging the adjusting wheel. The adjusting wheel then drives the rotating column, bevel gear three, bevel gear three, rotating shaft, bevel gear two, and bevel gear one to rotate. This, in turn, drives the cutting head to rotate via the shaft, allowing for angle adjustment. After adjustment, moving the lever backwards causes the sliding block to engage the insertion rod with the insertion hole under the rebound of the telescopic rod and the spring, locking the adjusting wheel. When using the glass cutting head, the angle can be adjusted, eliminating the need to change cutting heads for different cutting scenarios. This adaptable design makes it easy to use.

The striking head 7 is a rubber striking head (the rubber material buffers the striking force and avoids glass breakage or surface indentation caused by the metal striking head). When using the glass cutting head, first hold the handle 6, then use the support cylinder 1, connecting block 2 and cutting head 3 to align the cutting blade 4 with the glass. The cutting blade 4 makes a mark on the glass surface. After making the desired mark, the glass is then struck by the striking head 7.

[0024] Adjustment mechanism 5 includes bevel gear 1 51, bevel gear 2 52, rotating shaft 53, bevel gear 3 54, cylinder 55, rotating column 56, and bevel gear 4 57. The rotating shaft 53 is rotatably connected to the rear wall of the support cylinder 1. Bevel gear 2 52 is fixedly sleeved on the outer wall of the front end of the rotating shaft 53. Bevel gear 1 51 is fixedly sleeved on the outer wall of the middle part of the rotating shaft. Bevel gear 1 51 meshes with bevel gear 2 52. A cylinder 55 is located on the rear side of the outer arc surface of the support cylinder 1. A rotating column 56 is rotatably connected to the top wall of the cylinder 55. Bevel gear 4 57 is fixedly sleeved on the outer wall of the lower end of the rotating column 56. Bevel gear 3 54 is fixedly sleeved on the outer wall of the rear end of the rotating shaft 53. Bevel gear 3 54 meshes with bevel gear 4 57. Adjustment mechanism 5 also includes an adjusting wheel 58. The upper end of the rotating column 56 is fixedly... The adjusting mechanism 5 includes a locking assembly 59, which is fixedly connected to an adjusting wheel 58. The locking assembly 59 includes an adjusting platform 591, a slider 596, a connecting rod 597, and connecting holes 588. The adjusting platform 591 is located on the outer arc surface of the cylinder 55. The slider 596 is slidably connected inside the adjusting platform 591. The connecting rod 597 is fixedly connected to the upper end of the slider 596. The upper edge of the adjusting wheel 58 has evenly distributed connecting holes 588. The connecting rod 597 is fitted into adjacent connecting holes 588. The locking assembly 59 also includes a telescopic rod 593 and a spring 594. The telescopic rod 593 is fixedly connected between the bottom wall of the adjusting platform 591 and the lower end of the slider 596. The spring 594 is sleeved on the outside of the telescopic rod 593. The locking assembly 59 also includes an L-shaped groove 59. 2. A lever 595 is attached to the left end of the adjusting table 591. An L-shaped groove 592 is provided on the left end of the slider 596. The outer surface of the lever 595 is slidably connected to the inner wall of the L-shaped groove 592. When the angle of the cutting head 3 needs to be adjusted, the lever 595 is moved. The lever 595 slides downward along the vertical section of the L-shaped groove 592. Then, the lever 595 is pushed forward and locked into the horizontal section of the L-shaped groove 592. The downward movement of the lever 595 will drive the slider 596, causing the insertion rod 597 to disengage from the insertion hole 588. At the same time, the downward movement of the slider 596 will compress the telescopic rod 593 and the spring 594. Then, the adjusting wheel 58 will be rotated, which will drive the rotating column 56 to rotate. The rotation of the rotating column 56 will drive the rotation of the fourth bevel gear 57. The rotation of the fourth bevel gear 57 will drive the rotation of the meshing third bevel gear 54. The rotation of the third bevel gear 54 will drive the rotation of the rotating shaft 53. The rotation of the rotating shaft 53 will drive the rotation of the second bevel gear 52. The rotation of the second bevel gear 52 will drive the rotation of the meshing first bevel gear 51. The rotation of the first bevel gear 51 will drive the cutting head 3 to rotate through the rotating shaft, thereby adjusting the angle of the rotating shaft connected to the cutting head 3. After adjusting to the required angle, by pushing the lever 595 backward, the lever 595 will disengage from the lock. Then, under the rebound of the telescopic rod 593 and the spring 594, the slider 596 will drive the insertion rod 597 to insert into the insertion hole 588, thereby locking the adjusting wheel 58. Then, the handle 6 can be gripped for use.

[0025] The working principle of the adjustable glass cutting head provided by this utility model is as follows: When using the glass cutting head, first hold the handle 6, then align the cutting blade 4 with the glass through the support cylinder 1, connecting block 2, and cutting head 3. The cutting blade 4 makes a mark on the glass surface. After making the desired mark, tap the glass with the striking head 7. When it is necessary to adjust the angle of the cutting head 3, move the lever 595. The lever 595 slides downward along the vertical section of the L-shaped slide groove 592. Then push the lever 595 forward. The lever 595 is locked in the horizontal section of the L-shaped slide groove 592. The downward movement of the lever 595 will drive the slider 596, causing the insertion rod 597 to disengage from the insertion hole 588. At the same time, the downward movement of the slider 596 will compress the telescopic rod 593 and the spring 594. Then rotate to adjust. The rotation of wheel 58 will drive the rotation column 56 to rotate, which in turn will drive the rotation of bevel gear 4 57. The rotation of bevel gear 4 57 will drive the rotation of bevel gear 3 54 through meshing, which will drive the rotation shaft 53 to rotate. The rotation of rotation shaft 53 will drive the rotation of bevel gear 2 52, which will drive the rotation of bevel gear 1 51 through meshing, which will drive the rotation of the cutting head 3 through the rotating shaft. This will adjust the angle of the rotating shaft connected to the cutting head 3. After adjusting to the required angle, by pushing the lever 595 backward, the lever 595 will disengage from the lock. Then, under the rebound of the telescopic rod 593 and the spring 594, the slider 596 will drive the insertion rod 597 to insert into the insertion hole 588, thereby locking the adjustment wheel 58. Then, the handle 6 can be gripped for use.
