[0028] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0029] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0030] An adjustable hidden hinge provided by some embodiments of the utility model will be described below in conjunction with the accompanying drawings.

[0031] Embodiment 1:

[0032] Combination Figure 1-Figure 4 As shown, the utility model provides an adjustable hidden hinge.

[0033] Specifically, it includes a first hinge piece 1 and a second hinge piece 2. The right side of the first hinge piece 1 is symmetrically connected with two groups of first hinge sleeves 3. The left side of the second hinge piece 2 is connected with a second hinge sleeve 4. A hollow shaft 11 is embedded in the second hinge sleeve 4 and the two groups of first hinge pieces 1. A rotating sleeve column 14 is penetrated between the hollow parts of the hollow shaft 11. An oil-absorbing cotton strip 12 is embedded in the inner side of the rotating sleeve column 14. A scraper ring 15 is sleeved on the outer side of the rotating sleeve column 14 and the outer side of the hollow shaft 11. The rotating sleeve column The side of 14 and the side of the hollow shaft 11 are both provided with through holes 17 at the corresponding positions. The through holes 17 are mainly used to facilitate the introduction of lubricating oil so that it can spread to each connection better. The bottom end of the rotating sleeve 14 is connected to the installation base box 6. The front end outer side of the installation base box 6 is embedded with a sealing plunger rod 8. The sealing plunger rod 8 is a movable component. While sealing the installation base box 6, it is also convenient to install the extension toggle block 16. The two sides of the sealing plunger rod 8 are symmetrically connected with the extension toggle blocks. 16, the outer side surface of the top extended end of the rotating sleeve 14 is threadedly sleeved with a connecting fixing block 9, and the bottom front side surface of the first hinge piece 1 and the second hinge piece 2 is provided with an embedding groove 7 corresponding to the extended toggle block 16. The embedding groove 7 is mainly convenient for embedding and hiding of the extended toggle block 16. The extended toggle block 16 can be embedded in the embedding groove 7, and the outer side surface of the scraper ring 15 is respectively fitted with the inner side surfaces of the hollow shaft 11, the two groups of first hinge sleeves 3 and the second hinge sleeves 4, and the bottom extended end of the oil-absorbing cotton strip 12 is located inside the installation bottom box 6. When the above-mentioned components are used, the oil-absorbing cotton strip 12 makes it more convenient to lubricate the connections between the internal components and improves wear resistance. At the same time, the first hinge piece 1 and the second hinge piece 2 are closed by rotating the hollow shaft 11, and the extended toggle block 16 is squeezed to drive the scraper ring 15 on the rotating sleeve 14, including the scraper ring 15 on the hollow shaft 11, to scrape and clean the gaps at the internal connections to prevent blockage, reduce wear, and improve overall durability.

[0034] Embodiment 2:

[0035] Combination Figure 1 and Figure 2 As shown, based on the first embodiment,

[0036] Specifically, a shifting block strip 10 is connected to the middle of the front end surface of the connecting and fixing block 9. The shifting block strip 10 is mainly used to facilitate the separation of the wave-connecting and fixing block 9 from the extended end of the rotating sleeve 14, so that the installation base box 6, the rotating sleeve 14 and the hollow shaft 11 are separated from each other, which is convenient for taking the hollow shaft 11 out, improving the convenience of disassembly and replacement, and improving the use effect.

[0037] Combination Figure 1 , Figure 2 and Figure 3 As shown, in the above embodiment,

[0038] Specifically, the front ends of the first hinge piece 1 and the second hinge piece 2 are both fitted and connected with rubber pads 13. The rubber pads 13 mainly play a role of buffering and protection when the first hinge piece 1 and the second hinge piece 2 are fitted with each other. Multiple groups of mounting holes 5 are symmetrically provided on the first hinge piece 1 and the second hinge piece 2. The mounting holes 5 are mainly for facilitating the installation of fixing bolts, and the rubber pads 13 extend inside the mounting holes 5, which also increases the effect of subsequent bolt fixing. The extended ends of the rubber pads 13 extend and are embedded inside the multiple groups of mounting holes 5.

[0039] The working principle and use process of the utility model are as follows: first, when in use, the lubricating oil is injected into the interior of the installation bottom box 6 by opening the sealing plunger rod 8 in advance, and the lubricating oil is introduced into the rotating sleeve column 14 through the guidance of the oil-absorbing cotton strip 12, and the lubricating oil spreads through the through hole 17 to the connection between the first hinge sleeve 3, the second hinge sleeve 4 and the hollow shaft 11. At the same time, when the first hinge piece 1 and the second hinge piece 2 are closed to each other, the extended toggle block 16 on the sealing plunger rod 8 at the front end of the installation bottom box 6 is squeezed to drive the rotating sleeve column 14 to make the scraper ring 15 clean and scrape the interior, and also The scraper ring 15 on the hollow shaft 11 is driven to scrape the inner wall to prevent clogging by foreign particles, thereby reducing wear and improving the durability of the hinge. Secondly, when the hollow shaft 11 needs to be removed, it is only necessary to loosen the top of the connecting fixed block 9 and the rotating sleeve 14 by moving the block bar 10, separate and install the bottom box 6, the rotating sleeve 14 and the hollow shaft 11, and directly take out the hollow shaft 11 from the first hinge piece 1 and the second hinge piece 2, saving time and effort for dismantling the entire hinge, improving the convenience of dismantling and replacing, and improving the use effect of the hinge.

[0040] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
