[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-2The utility model provides a technical solution: a novel glass door hinge, comprising a base 1, a mounting block 2 and a fan blade 3, wherein the base 1 and the mounting block 2 are fixedly mounted by screws.
[0022] See also Figure 3-5 The inner cavity of the mounting block 2 is rotatably sleeved with the main shaft 4, and the bottom of the mounting block 2 is inlaid with a limiting plate 5. The buffer cylinder 6 is fixedly sleeved on the surface of the limiting plate 5, and the bottom abuts against the groove on the surface of the base 1. The spring 7 passes through the surface of the limiting plate 5 and abuts against the groove on the surface of the base 1. The inner cavities on both sides of the mounting block 2 are symmetrically fixedly sleeved with sealing rings 9 and rubber rings 10, and the two ends of the main shaft 4 are located in the inner cavity of the sealing rings 9 and the rubber rings 10. The sealing ring 9 is flush with the side of the mounting block 2, which is used for the rotation stability and sealing of the main shaft 4. The surface of the buffer cylinder 6 is provided with a jacket, which is installed upside down for use. The provided jacket can prevent direct contact with the main shaft 4 to reduce friction.
[0023] The end of the main shaft 4 extends out of the side of the mounting block 2 and is provided with a groove, and is fixedly sleeved with the fan blade 3 through the groove, so that the fan blade 3 drives the main shaft 4 to rotate in the inner cavity of the mounting block 2, and a recessed groove 42 is provided in the middle of the main shaft 4, and an extrusion end 43 is integrally extended at one end of the recessed groove 42, and arc ends 41 are provided at both ends of the main shaft 4, which will be more stable after contacting with the steel ball 11 through the arc end 41, and a buffer cylinder 6 is fixedly sleeved in the middle of the inner cavity of the mounting block 2, and springs 7 are provided on both sides of the buffer cylinder 6 and located in the inner cavity of the mounting block 2, and a cover 8 is fixedly connected to the top of the spring 7, and steel balls 11 are provided in the inner cavity of the cover 8 and the top of the buffer cylinder 6, and the steel balls 11 are located below the arc end 41, and the top of the buffer cylinder 6 is located below the extrusion end 43 and abuts against the extrusion end 43.
[0024] During operation, first install the base 1 and the mounting block 2 on the glass door respectively. When closing the door, the fan blade 3 drives the main shaft 4 to rotate 90 degrees in the inner cavity of the mounting block 2, and the buffer cylinder 6 located in the inner cavity of the recessed groove 42 will be squeezed, so that the outer sleeve on the top of the buffer cylinder 6 will contact the extrusion end 43. At the same time, under the elastic force of the spring 7, the steel ball 11 in the inner cavity of the cover 8 will be driven to contact the arc surface end 41, which will be more stable without shaking.
[0025] When the door is opened, the main shaft 4 rotates ninety degrees in the opposite direction, the extrusion end 43 will leave the buffer cylinder 6, and the buffer cylinder 6 will be extended and retracted little by little along the arc surface of the recessed groove 42 into the recessed groove 42, and an extrusion force will be formed. At the same time, the steel ball 11 will also contact the steel ball 11 along the arc surface of the roller and the surface of the main shaft 4. Since the height of the arc surface is greater than the arc surface end 41, the spring 7 will be squeezed to start tightening, so that the door opening will have a buffering effect. Through the spring 7, steel ball 11 and the micro steel ball on the top of the buffer cylinder 6, when the main shaft 4 closes and opens the door, after the extrusion buffer structure is squeezed, it will not directly squeeze and slide with the extrusion buffer, but will be rolled and squeezed by the steel ball 11, so that the steel ball 11 can play a smooth opening and closing for long-term opening and closing, and there will be no friction sound and opening and closing problems without smoothness due to long-term friction.
