Description

Technical Field

[0001] The utility model relates to the field of hardware hinges, in particular to a novel hardware buffer hinge. Background Art

[0002] A hinge, also known as a hinge, is a mechanical device used to connect two solids and allow them to rotate relative to each other. A hinge can be made of movable components or foldable materials. Hinges are mainly installed on doors and windows, while hinges are more often installed on cabinets. They are mainly divided into stainless steel hinges and iron hinges according to the material classification. In order to give people a better enjoyment, hydraulic hinges (also known as buffer hinges) have emerged. Their characteristic is that they provide a buffer function when the cabinet door is closed, which minimizes the noise caused by the collision between the cabinet door and the cabinet body when it is closed.

[0003] The existing technology has the following deficiencies: the internal structure of the existing buffer hinge is relatively complex. When the hinge is closed, the spring drives the connecting plate to pull the piston rod of the cylinder forward to achieve a buffering effect. However, during the entire hinge closing process, only the piston rod extends and the cylinder body does not move. Impact and vibration are easily generated during the extension of the piston rod, which may affect the stability and life of the hinge mechanical system; and the frequent unidirectional movement of the piston rod will cause a large movement load on the piston rod, which may cause serious wear on the surface of the piston rod, thereby reducing the buffering performance of the hinge.

[0004] Therefore, it is necessary to invent a new type of hardware buffer hinge. Utility Model Content

The oil core includes an oil core rod and an oil cylinder, and the end of the oil core rod in the oil core away from the oil cylinder is close to the side of the bending piece away from the torsion spring.

A torsion spring 18 is installed between the connecting rod 13 and the lower connecting rod 15, a bending piece 19 is provided in the middle of one end of the hinge arm body 12 connected to the upper connecting rod 13, an oil core sleeve 16 is slidably installed on the inner wall of the bottom surface of the hinge arm body 12, an oil core 17 is slidably installed on the inner wall of the oil core sleeve 16, one end of the oil core 17 is against the bending piece 19, and a hook groove is provided at one end of the lower connecting rod 15 that is rotatably connected to the hinge arm body 12, and the hook groove of the lower connecting rod 15 can hook the oil core sleeve 16.

[0021] In the above embodiment, it should be noted that the oil core 17 and the cylinder sleeve 16 are combined into an integrated cylinder assembly. When the cup head 11 and the hinge arm body 12 are rotated and closed, the oil core sleeve 16 is hooked by the lower connecting rod 15 to make a linear motion. The oil core sleeve 16 slides along the inner wall of the hinge arm body 12 toward the cup head 11 and squeezes the oil core 17. Finally, the oil core 17 shrinks under the squeezing of the oil core sleeve 16 and the bending piece 19, so as to achieve the effect of replacing the traditional oil core extension buffering method with the oil core retraction buffering method, avoiding the impact and vibration effect during the extension of the oil core 17, optimizing the internal structure of the hinge, making the connection structure simpler, more practical and durable, saving production costs, and improving the practicality of the product; and when the hinge is closed, the cylinder assembly moves as a whole, sharing the movement load of the oil core rod, alleviating the surface wear of the oil core rod, thereby improving the buffering performance of the hinge.

[0022] Example 2

In addition, a hanging ear is provided at one end of the oil core sleeve 16 close to the cup head 11, and the hanging ear of the oil core sleeve 16 is inserted into the hook groove of the lower connecting rod 15. When the lower connecting rod 15 swings, it can drive the oil core sleeve 16 to move linearly. A rivet 20 is provided at the lower part of the oil core sleeve 16, and the rivet 20 is inserted and installed on the hinge arm body 12.

[0024] In the above embodiment, it should be noted that when the cup head 11 and the hinge arm body 12 are rotated and closed, the hook groove of the lower connecting rod 15 hooks the hanging ear of the oil core sleeve 16 to achieve the effect of driving the oil core sleeve 16 to move linearly; the rivet 20 has a limiting effect on the oil core sleeve 16, which can prevent the oil core sleeve 16 from falling out of the hinge arm body 12.

[0025] Example 3

In addition, the bending piece 19 is stamped from the surface of the hinge arm 12, and the side of the bending piece 19 close to the torsion spring 18 is tangent to the torsion spring 18. The oil core 17 includes an oil core rod and an oil cylinder. The end of the oil core rod in the oil core 17 away from the oil cylinder is close to the side of the bending piece 19 away from the torsion spring 18.

[0027] In the above embodiment, it should be noted that an R angle of more than 1.5MM is set on the outer side of the bending angle of the bending piece 19, which can extend the service life of the bending piece 19. The oil core rod in the oil core 17 plays the role of a buffer hinge by extending or retracting in the oil cylinder.

[0028] Example 4

[0029] like Figure 1 and Figure 2 As shown, a new type of hardware buffer hinge includes all the contents of Example 1. In addition, a U-needle 14 is inserted and installed on the side of the cup head 11, and the two ends of the U-needle 14 respectively penetrate the upper connecting rod 13 and the lower connecting rod 15. The upper connecting rod 13 and the lower connecting rod 15 are rotatably connected to the cup head 11 through the U-needle 14.

[0030] In the above embodiment, it should be noted that the U-needle 14 is made of metal, and the upper connecting rod 13 and the lower connecting rod 15 are rotatably connected to the cup head 11 through the U-needle 14 .

[0031] Example 5

[0032] like Figure 1 and Figure 2As shown, a new type of hardware buffer hinge includes all the contents of Example 1. In addition, a base 21 is installed on the bottom surface of the hinge arm body 12, and a first adjusting screw 22 and a second adjusting screw 23 are inserted into the top surface of the hinge arm body 12. The first adjusting screw 22 and the second adjusting screw 23 pass through the hinge arm body 12 and the base 21.

[0033] In the above embodiment, it should be noted that the base 21 can be fixedly mounted on the cabinet door or cabinet surface by bolts, and the relative position of the hinge arm 12 and the base 21 can be adjusted by adjusting the first adjusting screw 22 and the second adjusting screw 23 .

[0034] The use process of the utility model is as follows: when a technician in this field rotates the cup head 11 and the hinge arm body 12 to close, the hook groove of the lower connecting rod 15 hooks the hanging ear of the oil core sleeve 16, driving the oil core sleeve 16 to move in a straight line, and the oil core sleeve 16 slides along the inner wall of the hinge arm body 12 toward the cup head 11 and squeezes the oil core 17. Finally, the oil core 17 shrinks under the squeezing of the oil core sleeve 16 and the bending sheet 19 to achieve a buffering effect.
