[0002] A hinge is a kind of furniture hardware fitting. A hinge is a mechanical device used to connect two solids and allow relative rotation between the two. A hinge can be composed of movable components or composed of foldable materials. Hinges are more installed on cabinets. Classified by material, they are mainly divided into stainless steel hinges and iron hinges. The characteristic of a hinge is that it brings a buffering function when the cabinet door is closed, minimizing the noise generated by the collision between the cabinet door and the cabinet body when the cabinet door is closed. Hinges can be divided into detachable and fixed types according to the base type, and can be divided into two types: sliding-in type and clamping type according to the type of the arm body. However, when the existing hinges are in use, lubricating oil cannot be quantitatively replenished, which easily causes the hinges to get stuck during use, resulting in the hinges not running smoothly enough and affecting the use of the hinges. Content of the Utility Model
[0003] The purpose of the utility model is to provide a hinge with self-lubrication to solve the problem that lubricating oil cannot be quantitatively replenished in the above background technique, which easily causes the hinges to get stuck during use, resulting in the hinges not running smoothly enough and affecting the use of the hinges.
[0004] To achieve the above purpose, the utility model provides the following technical solution: A hinge with self-lubrication, including an installation seat which is set as a square plate structure, and a shaft rod is rotatably installed on the surface of the installation seat;
[0005] Oil grooves are symmetrically embedded on the surface of the shaft rod, and rubber blocks are embedded in the interior of the oil grooves. A main body is sleeved on the surface of the shaft rod;
[0006] A lubrication mechanism is arranged on the surface of the installation seat, and the lubrication mechanism includes: A storage box is fixedly installed on the surface of the installation seat, and pipes are symmetrically installed at the bottom of the storage box. Limit blocks are fixedly and symmetrically connected to the surface of the shaft rod.

[0007] Preferably, the shaft rod and the installation seat are fixedly connected, the main body and the shaft rod are rotatably connected, and the shaft rod and the installation seat are rotatably connected.
[0008] By adopting the above technical solution, when the main body rotates, it rotates on the surface of the shaft rod, and at this time, the main body rotates inside the installation seat.
[0009] Preferably, the outer side of the rubber block is in contact with the surface of the main body, and the main body and the rubber block are slidably connected.
[0010] With the above technical solution, when the end of the rubber block contacts the main body, friction can be generated with the main body, and at this time, the main body is lubricated through the rubber block.
[0011] Preferably, the end of the pipe penetrates through the mounting seat and is close to the shaft rod, and the end of the pipe is arranged corresponding to the position of the oil sump.
[0012] With the above technical solution, the lubricating oil entering the pipe causes the internal lubricating oil to fall into the oil sump through the pipe.
[0013] Preferably, the rotating plate and the shaft rod are arranged as a sliding structure, and the rotating plate and the shaft rod are arranged corresponding to each other.
[0014] With the above technical solution, the main body drives the rotating plate to rotate on the shaft rod, and at this time, the rotating plate rotates on the surface of the shaft rod.
[0015] Preferably, the end of the convex block is in contact with the surface of the pipe, the surface of the pipe is symmetrically provided with convex blocks and limiting blocks, and the pipe is connected through with the storage box.
[0016] With the above technical solution, when the convex block moves to one side of the pipe, the pipe can be extruded, so that the inside of the pipe is closed, preventing the lubricating oil inside the pipe from falling.
[0017] Preferably, one side of the limiting block is in contact with the surface of the pipe, and the pipe is embedded inside the limiting block.
[0018] With the above technical solution, the limiting block can limit one side of the pipe.
[0019] Compared with the prior art, the beneficial effects of the present utility model are: The hinge provided with self-lubrication:
[0020] 1. A lubrication mechanism is provided, which can lubricate the shaft rod to prevent the main body from jamming when rotating. When the main body rotates, the main body drives the convex block to rotate through the rotating plate. At this time, the extrusion of the pipe by the convex block is lost, and the lubricating oil inside the storage box falls into the oil sump through the pipe, which can timely replenish the lubricating oil for the shaft rod and improve the practicability of the device;
[0021] 2. An oil sump and a clamping block are provided. The lubricating oil moves downward along the oil sump, enabling the lubricating oil to fully contact the main body. At the same time, the lubricating oil can be stored through the oil sump. Meanwhile, the rubber block contacts the surface of the main body, which can reduce the contact area between the shaft rod and the main body and improve the smoothness of the use of the main body.

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0033] Please refer to Figures 1-6 , the present utility model provides a technical solution: a hinge with self-lubrication, including a mounting seat 10, a shaft rod 20, an oil groove 201, a rubber block 202, a main body 30, a storage box 40, a pipeline 401, a rotating plate 402, a convex block 403 and a limiting block 404;
[0034] This hinge can lubricate the interior. The specific implementation manner is as follows:
[0035] The mounting seat 10 is set as a square plate structure, and the shaft rod 20 is rotatably installed on the surface of the mounting seat 10; the oil grooves 201 are symmetrically embedded on the surface of the shaft rod 20, and the rubber block 202 is embedded and installed inside the oil grooves 201, and the main body 30 is sleeved and installed on the surface of the shaft rod 20;
[0036] The surface of the mounting base 10 is provided with a lubrication mechanism, and the lubrication mechanism includes: a storage box 40 is fixedly installed on the surface of the mounting base 10, and pipes 401 are symmetrically installed at the bottom of the storage box 40. Limiting blocks 404 are fixedly and symmetrically connected to the surface of the shaft rod 20. A rotating plate 402 is fixedly connected to the surface of the main body 30, and a convex block 403 is fixedly connected to the surface of the rotating plate 402. The shaft rod 20 is fixedly connected to the mounting base 10, and the main body 30 is rotatably connected to the shaft rod 20, and the shaft rod 20 is rotatably connected to the mounting base 10. The outer side of the rubber block 202 is in contact with the surface of the main body 30, and the main body 30 is slidably connected to the rubber block 202. The end of the pipe 401 penetrates through the mounting base 10 near the shaft rod 20, and the end of the pipe 401 is correspondingly arranged with the oil groove 201. The rotating plate 402 and the shaft rod 20 are arranged as a sliding structure, and the rotating plate 402 and the shaft rod 20 are correspondingly arranged. The end of the convex block 403 is in contact with the surface of the pipe 401. Convex blocks 403 and limiting blocks 404 are symmetrically arranged on the surface of the pipe 401, and the pipe 401 is connected to the storage box 40 in a through manner. One side of the limiting block 404 is in contact with the surface of the pipe 401, and the pipe 401 is embedded inside the limiting block 404.
[0037] When the main body 30 rotates, the main body 30 rotates on the surface of the shaft rod 20, and at the same time, the main body 30 rotates inside the mounting base 10. At this time, the main body 30 drives the rotating plate 402 on the surface to rotate, and the rotating plate 402 drives the convex block 403 to rotate. At this time, the convex block 403 rotates out from one side of the pipe 401, and the convex block 403 loses the extrusion on the pipe 401. At this time, the lubricating oil inside the storage box 40 drops due to gravity. At this time, the lubricating oil inside the storage box 40 enters the inside of the pipe 401, and falls into the oil groove 201 through the pipe 401, and the lubricating oil falls along the inner wall of the oil groove 201. At this time, the lubricating oil contacts the surface of the convex block 403. At this time, when the main body 30 rotates, the main body 30 rotates on the surface of the convex block 403. At this time, the lubricating oil on the surface of the convex block 403 contacts the inside of the main body 30. At this time, the lubricating oil can lubricate between the main body 30 and the shaft rod 20. When the position of the main body 30 is restored, the main body 30 drives the shaft rod 20 to rotate in the reverse direction, and the shaft rod 20 drives the convex block 403 to rotate to one side of the pipe 401, so that the convex block 403 squeezes the pipe 401, and fixes the pipe 401 between the limiting block 404 and the convex block 403. At this time, the pipe 401 can be blocked to prevent the lubricating oil inside the pipe 401 from falling.
[0038] Working principle: When using the hinge with self-lubrication, the storage box 40, the pipe 401, the convex block 403 and the limiting block 404 are provided, which can lubricate the inside and increase the overall practicability.
[0039] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art will appreciate that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
