Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically to an oil-lubricated adjustable hinge. Background Technology

[0002] Hinges are generally used to connect two objects and allow them to rotate relative to each other. Existing hinges typically consist of a spindle (also called a pivot) and two hinge plates with bushings fitted onto the spindle.

[0003] Currently, hinge lubrication generally uses oil injection, which means that lubricating oil is only used when there is high rotational resistance during use. This results in delayed lubrication and is prone to friction damage, affecting the user experience. Utility Model Content

[0004] This invention proposes an oil-lubricated adjustable hinge, which solves the problem of delayed lubrication during the use of existing hinges, thus affecting the user experience.

[0005] The technical solution of this utility model is as follows:

[0006] An oil-lubricated adjustable hinge includes a first page body, a second page body, and a hinge shaft. The first page body has an oil storage channel and a mating channel connected sequentially. One end of the hinge shaft is disposed within the second page body, and the other end extends into the mating channel and is rotatable relative to the mating channel. The hinge also includes a wear-resistant block disposed within the mating channel, which limits the hinge shaft. The wear-resistant block has an oil passage hole connecting the oil storage channel and the mating channel.

[0007] The hinge shaft has a threaded section at one end located inside the second page body, and the relative position between the hinge shaft and the second page body can be adjusted by means of the threaded section.

[0008] The hinge also includes a rotating ball, which is disposed between the wear-resistant block and the hinge shaft. Both the wear-resistant block and the hinge shaft have an arc-shaped groove at one end near the rotating ball.

[0009] The oil passage hole on the wear-resistant block is set off-center.

[0010] The hinge also includes a rust-proof sleeve, which is disposed within the mating channel, and the hinge shaft passes through the rust-proof sleeve.

[0011] The rust-proof sleeve has an opening on its circumference near one end of the wear-resistant block, and the rust-proof sleeve has a reverse tooth on the same end near the wear-resistant block. An annular groove is provided in the mating channel, and the reverse tooth is used to engage with the annular groove.

[0012] The hinge also includes two plugs, which are located at the ends of the first page and the second page.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] This utility model discloses a lubricated adjustable hinge. The hinge shaft is installed on the second hinge body, and then inserted into a mating channel on the first hinge. A wear-resistant block is also provided in the mating channel to limit the position of the hinge shaft. An oil storage channel is provided on the side of the wear-resistant block opposite to the hinge shaft, containing lubricating oil. An oil passage hole is provided on the wear-resistant block. The lubricating oil in the oil storage channel is gradually released through the oil passage hole between the hinge shaft and the mating channel, thereby achieving a good continuous lubrication effect. This solves the problem of delayed lubrication during hinge use in the prior art, which affects the user experience. Attached Figure Description

[0020] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0021] like Figures 1-3As shown in the figure, this embodiment proposes an oil-lubricated adjustable hinge. The hinge includes a first page body 1, a second page body 2, and a hinge shaft 3. The first page body 1 is provided with an oil storage channel 4 and a mating channel 5 connected in sequence. One end of the hinge shaft 3 is disposed in the second page body 2, and the other end of the hinge shaft 3 extends into the mating channel 5 and can rotate relative to the mating channel 5. The hinge also includes a wear-resistant block 6, which is disposed in the mating channel 5 and is used to limit the hinge shaft 3. The wear-resistant block 6 is provided with an oil passage hole 7, which is used to connect the oil storage channel 4 and the mating channel 5.

[0022] In this embodiment, a lubricated adjustable hinge is disclosed. The hinge shaft 3 is installed on the second hinge body 2, and then the hinge shaft 3 is inserted into the mating channel 5 on the first hinge. A wear-resistant block 6 is also provided in the mating channel 5. The wear-resistant block 6 can limit the position of the hinge shaft 3. An oil storage channel 4 is provided on the side of the wear-resistant block 6 away from the hinge shaft 3. Lubricating oil is stored in the oil storage channel 4. An oil passage hole 7 is provided on the wear-resistant block 6. The lubricating oil in the oil storage channel 4 will be gradually released into the space between the hinge shaft 3 and the mating channel 5 through the oil passage hole 7, thereby achieving a good continuous lubrication effect.

[0023] The hinge shaft 3 has a threaded section at one end located inside the second page body 2, and the relative position between the hinge shaft 3 and the second page body 2 can be adjusted by means of the threaded section.

[0024] In this embodiment, the hinge shaft 3 is positioned in an adjustable position within the second page body 2. In a possible implementation, one end of the hinge shaft 3 within the second page body 2 is provided with a threaded section, and the hinge shaft 3 is threadedly connected to the second page body 2. By adjusting the depth of screwing in, the distance between the first page body 1 and the second page body 2 can be adjusted.

[0025] The hinge also includes a rotating ball 8, which is disposed between the wear-resistant block 6 and the hinge shaft 3. Both the wear-resistant block 6 and the hinge shaft 3 have an arc-shaped groove at one end near the rotating ball 8.

[0026] In this embodiment, a rotating ball 8 is provided between the wear-resistant block 6 and the hinge shaft 3 to improve the smoothness of rotation. At the same time, an arc-shaped groove is also provided at the end of the wear-resistant block 6 and the hinge shaft 3 near the rotating ball 8 to stabilize the position of the rotating ball 8.

[0027] The oil passage 7 on the wear-resistant block 6 is set off-center.

[0028] In this embodiment, the oil passage hole 7 on the wear-resistant block 6 is set off-center, thereby slowing down the rate of oil passage at the opening 10 of the oil passage hole 7 and prolonging the duration of lubrication.

[0029] The hinge also includes a rust-proof sleeve 9, which is disposed within the mating channel 5, and the hinge shaft 3 passes through the rust-proof sleeve 9.

[0030] In this embodiment, a rust-proof sleeve 9 is provided in the mating channel 5. The rust-proof sleeve 9 can be made of copper, which can prevent rusting and extend service life.

[0031] The rust-proof sleeve 9 has an opening 10 on its circumference near one end of the wear-resistant block 6, and a reverse tooth 11 is provided on the other end of the rust-proof sleeve 9 near the wear-resistant block 6. An annular groove 12 is provided in the mating channel 5, and the reverse tooth 11 is used to engage with the annular groove 12.

[0032] In this embodiment, the rust-proof sleeve 9 is fixed by cooperating with the annular groove 12 in the mating channel 5. The end face of the rust-proof sleeve 9 is provided with an opening 10 and a reverse tooth 11 is provided at the end. When the rust-proof sleeve 9 is installed, the rust-proof sleeve 9 can be retracted and inserted because of the opening 10, until the reverse tooth 11 is engaged with the annular groove 12 to achieve fixation.

[0033] The hinge also includes two plugs 13, which are respectively disposed at the ends of the first page body 1 and the second page body 2.

[0034] In this embodiment, two plugs 13 are also provided at the ends of the first page 1 and the second page 2. One plug 13 blocks the oil storage channel 4, and the other plug 13 can block the hole on the second page 2 where the rotating shaft is installed.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
