Description

Technical Field

[0001] This utility model relates to the field of hinge body technology, and in particular to a machined hinge body. Background Technology

[0002] A hinge is a component widely used in mechanical structures and engineering. It typically consists of two or more rotatable parts connected by a shaft or pin. The hinge enables relative rotation between two connected parts, playing a crucial role in connection and movement in various devices and apparatuses. In everyday life, we see it used in doors and windows, allowing them to open and close flexibly. In industry, it has important applications at the joints of robotic arms, ensuring that different parts of the arm can change angles as needed to precisely complete various operations. In furniture manufacturing, hinges facilitate the opening and closing of cabinet doors and other components, providing a convenient user experience. In short, with its unique rotatable connection characteristics, the hinge plays an indispensable role in many fields and is a vital component for achieving flexible connections and relative movement between objects.

[0003] A hinge body typically consists of a fixed plate and a fixed seat, which are then connected to other connecting parts via a hinge shaft. However, the gap between the hinge shaft and the fixed seat is small after installation, making it difficult to add lubricating oil between the hinge shaft and the fixed seat. The lack of lubricating oil will lead to increased friction, resulting in accelerated wear of the hinge shaft and the inner wall of the mounting hole, thus shortening its service life. Therefore, we propose a machined hinge body. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a machined hinge body.

[0005] This utility model is achieved using the following technical solution: a hinge body machining part, including a fixing plate, a fixing seat fixedly connected to the bottom of the fixing plate, two fixing seats, an oil inlet hole opened on the inner wall of each fixing seat, an installation hole opened on the inner wall of the fixing seat, a plurality of oil outlet holes opened on the inner wall of the oil inlet hole, the oil outlet holes communicating with the installation hole, an installation seat provided on the top of the fixing plate, a positioning groove opened on the top of the fixing plate, a limiting groove opened on the top of the fixing plate, a positioning block provided inside the positioning groove, a limiting protrusion fixedly connected to the surface of the positioning block, and a fastening bolt provided in the middle of the fixing plate.

[0006] The above technical solution facilitates the connection and fixation of the hinge shaft via mounting blocks on the inner walls of the two fixed seats, thus enabling the installation of the connecting parts. The mounting seats, in conjunction with bolts, can be installed in the desired position. The hinge shaft can also be connected to external connecting parts via the mounting seats. When lubricating oil needs to be added to the hinge shaft, it is added through the oil inlet holes and then evenly distributed into the mounting holes through several oil outlet holes, lubricating the hinge shaft, reducing friction between the hinge shaft and the inner wall of the mounting holes, extending the service life of the hinge body, facilitating quick lubrication of the hinge shaft, simplifying operation, and providing rust prevention, further improving the durability of the hinge body. The four oil inlet holes are symmetrically distributed around the mounting holes of the two fixed seats, allowing for the use of different inlet holes depending on the installation position of the fixed seats. When lubricating oil enters the oil inlet holes, gravity causes it to exit through the oil outlet holes into the mounting holes.

[0007] As a further improvement to the above solution, the size of the positioning groove is adapted to the size of the positioning block, and the top of the positioning block is fixedly connected to the bottom of the mounting base.

[0008] The above technical solution utilizes positioning slots to place positioning blocks, facilitating quick installation and improving operational convenience.

[0009] As a further improvement to the above solution, the number of the limiting grooves is set to four, and the four limiting grooves are arranged in a circle around the positioning groove.

[0010] With the above technical solution, since there are four limiting grooves, the limiting protrusions can be installed in the limiting grooves at different positions, which facilitates the subsequent adjustment of the position of the mounting base.

[0011] As a further improvement to the above solution, the surface of the limiting protrusion contacts the inner wall of the limiting groove.

[0012] Through the above technical solution, when the limiting protrusion enters the interior of the limiting groove, it plays a limiting role on the mounting block and mounting seat, ensuring accurate installation position, facilitating subsequent installation, and improving installation precision.

[0013] As a further improvement to the above solution, the number of the limiting protrusions is set to two, and the two limiting protrusions are arranged in a circle around the positioning block.

[0014] Through the above technical solution, the two limiting protrusions improve the limiting effect on the mounting block and mounting base, preventing the mounting block and mounting base from rotating during use.

[0015] As a further improvement to the above solution, threaded holes are provided on the inner walls of the fixing plate, mounting base and positioning block.

[0016] The above technical solution connects the fixed plate, mounting base, and mounting block through threaded holes and fastening bolts. When the fastening bolts enter the interior of the threaded holes, they can be installed and fixed. The structure is simple, easy to use, and convenient for subsequent disassembly.

[0017] As a further improvement to the above solution, the inner wall of the threaded hole is threaded with a fastening bolt.

[0018] With the above technical solution, one end of the fastening bolt extends into the interior of the mounting base, ensuring the stability of the installation.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This utility model, by setting a fixing plate, a fixing seat, an oil inlet hole, and an oil outlet hole, specifically, when it is necessary to add lubricating oil to the hinge shaft, the lubricating oil is added through the oil inlet hole, and then evenly distributed into the interior of the mounting hole through several oil outlet holes to lubricate the hinge shaft, reduce the friction between the hinge shaft and the inner wall of the mounting hole, extend the service life of the hinge body, facilitate quick lubrication of the hinge shaft, is simple and convenient to operate, and also plays a role in rust prevention, further improving the durability of the hinge body.

[0021] This utility model utilizes a positioning groove, a limiting groove, a positioning block, a limiting protrusion, and fastening bolts. Specifically, by lifting and rotating the mounting base upwards by 90 degrees, the positioning block is placed inside the positioning groove, which initially limits the positioning of the positioning block. Simultaneously, the limiting protrusion enters the limiting groove, which limits the position of the limiting protrusion, preventing installation position deviations and preventing rotation of the positioning block and mounting base. Then, the fastening bolts connect to the threaded holes on the inner walls of the fixing plate, mounting base, and positioning block, thereby fixing the mounting base. The operation is simple, and the installation angle of the mounting base can be easily adjusted according to needs, improving the flexibility of use. Attached Figure Description

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example:

[0031] Please combine Figure 1-5 This embodiment of a hinge body processing component includes a fixing plate 1. A fixing seat 2 is fixedly connected to the bottom of the fixing plate 1. Two fixing seats 2 are provided. Each fixing seat 2 has an oil inlet hole 3 on its inner wall, and an installation hole on its inner wall. Several oil outlet holes 4 are provided on the inner wall of the oil inlet hole 3, communicating with the installation hole. An installation seat 5 is provided on the top of the fixing plate 1. A positioning groove 6 and a limiting groove 7 are provided on the top of the fixing plate 1. A positioning block 8 is provided inside the positioning groove 6. The surface is fixedly connected with a limiting protrusion 9, and a fastening bolt 10 is provided in the middle of the fixing plate 1. The hinge shaft is installed through the mounting hole on the inner wall of the fixing seat 2. When it is necessary to add lubricating oil to the hinge shaft, the lubricating oil is added through the oil inlet 3, and then evenly distributed into the interior of the mounting hole through several oil outlet holes 4 to lubricate the hinge shaft, reduce the friction between the hinge shaft and the inner wall of the mounting hole, extend the service life of the hinge body, facilitate quick lubrication of the hinge shaft, and is simple and convenient to operate. It also plays a role in rust prevention and further improves the durability of the hinge body.

[0032] The dimensions of the positioning groove 6 are adapted to the dimensions of the positioning block 8. The top of the positioning block 8 is fixedly connected to the bottom of the mounting base 5. By removing the fastening bolt 10, the mounting base 5 is removed from its fixation. The mounting base 5 is lifted upwards and rotated 90 degrees. The positioning block 8 is placed inside the positioning groove 6, which initially limits the positioning of the positioning block 8. At the same time, the limiting protrusion 9 enters the limiting groove 7, which limits the position of the limiting protrusion 9, preventing deviation in the installation position and preventing the positioning block 8 and the mounting base 5 from rotating. It also facilitates the adjustment of the installation angle of the mounting base 5 as needed, improving the flexibility of use.

[0033] There are four limiting grooves 7, which are arranged circumferentially around the positioning groove 6. Since there are four limiting grooves 7, the limiting protrusions 9 can be installed in the limiting grooves 8 at different positions, which facilitates the subsequent adjustment of the position of the mounting base 5.

[0034] The surface of the limiting protrusion 9 contacts the inner wall of the limiting groove 7.

[0035] There are two limit protrusions 9, which are arranged in a circle around the positioning block 8.

[0036] The inner walls of the fixing plate 1, the mounting base 5, and the positioning block 8 are all provided with threaded holes.

[0037] The inner wall of the threaded hole is connected to a fastening bolt 10. The fastening bolt 10 is connected to the threaded hole on the inner wall of the fixing plate 1, the mounting base 5 and the positioning block 8 to fix the mounting base 5. The operation is simple and convenient, and it is also easy to disassemble it later.

[0038] The implementation principle of the hinge body processing component in this application embodiment is as follows: During use, the hinge shaft is installed through the mounting holes on the inner wall of the fixing seat 2. When lubricating oil needs to be added to the hinge shaft, it is added through the oil inlet 3, and then evenly distributed into the interior of the mounting hole through several oil outlet holes 4, thus lubricating the hinge shaft. This reduces the friction between the hinge shaft and the inner wall of the mounting hole, extending the service life of the hinge body. It facilitates quick and easy lubrication of the hinge shaft, is simple and convenient to operate, and also provides rust prevention, further improving the durability of the hinge body. When the installation angle of the mounting seat 5 needs to be adjusted, the fastening bolts 10 are removed to release the... To fix the mounting base 5, lift the mounting base 5 upwards and rotate it 90 degrees, placing the positioning block 8 inside the positioning groove 6. The positioning groove 6 initially limits the positioning block 8, while the limiting protrusion 9 enters the limiting groove 7, limiting the position of the limiting protrusion 9 to prevent deviation in the installation position and to prevent the positioning block 8 and the mounting base 5 from rotating. Then, the mounting base 5 is fixed by connecting the fastening bolt 10 to the threaded holes on the inner walls of the fixing plate 1, the mounting base 5, and the positioning block 8. The operation is simple and allows for easy adjustment of the installation angle of the mounting base 5 as needed, improving the flexibility of use.
