DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-4 As shown, a detachable cylindrical silent hinge includes a first connecting seat 1, a hinge shaft 13, a second connecting seat 2 and a noise reduction sleeve 3. The first connecting seat 1 and the second connecting seat 2 are both plugged with noise reduction sleeves 3, and the outer surfaces of the noise reduction sleeves 3 fit the inner walls of the first connecting seat 1 and the second connecting seat 2. The hinge shaft 13 is plugged into the noise reduction sleeves 3 of the first connecting seat 1 and the second connecting seat 2. Pushing seats 5 are provided in the first connecting seat 1 and the second connecting seat 2. The ends of the noise reduction sleeves 3 are in contact with the pushing seats 5. Plug-in blocks 6 are symmetrically provided in the pushing seats 5. The first connecting seat 1 and the second connecting seat 2 are both provided with sliding grooves 11 corresponding to the plug-in blocks 6, and the plug-in blocks 6 are slidably installed in the sliding grooves 11.

[0024] The utility model provides a noise reduction sleeve 3, which can prevent the noise generated by friction between components during the rotation of the hinge, thereby achieving a silent effect; reducing hinge wear, extending the service life of the hinge, and reducing maintenance costs. The plug-in block 6 cooperates with the pushing seat 5 to push the noise reduction sleeve 3, so that the noise reduction sleeve 3 can be moved out from the first connecting seat 1 and the second connecting seat 2, so that the noise reduction sleeve 3 can be replaced.

[0025] Specifically, two groups of jacks 8 and positioning grooves 9 are symmetrically provided in the push seat 5, the jacks 8 are connected with the positioning grooves 9, and the plug-in block 6 is dampedly plugged in the jacks 8 and the positioning grooves 9. The above design, through the setting of the positioning grooves 9, through the cooperation of the jacks 8 and the positioning grooves 9, the plug-in block 6 can be stored.

[0026] Specifically, the end of the plug-in block 6 is fixedly connected with a positioning block 10, and the positioning block 10 is in contact with the inner wall of the positioning groove 9. The above design can play a role in positioning the plug-in block 6 through the cooperation of the positioning block 10 and the positioning groove 9, and can prevent the plug-in block 6 from falling from the push seat 5.

[0027] Specifically, the surface of the push seat 5 is in contact with the inner walls of the first connection seat 1 and the second connection seat 2, and the end of the plug-in block 6 is fixedly connected with an arc block 7 for withdrawing the plug-in block 6. The above design facilitates the withdrawal of the plug-in block 6 from the push seat 5 through the arrangement of the arc block 7.

[0028] Specifically, the noise reduction sleeve 3 is made of rubber. The above design, through the setting of the noise reduction sleeve 3, is not easy to generate noise during the hinge rotation process, and is easy to batch mold, with high production efficiency and low cost;

[0029] Specifically, a fixing ring 4 is sleeved on the hinge shaft 13, and the fixing ring 4 is arranged between the noise reduction sleeves 3 on the first connecting seat 1 and the second connecting seat 2. A top ring 17 is arranged in the first connecting seat 1 and the second connecting seat 2, and the push seat 5 is in contact with the top ring 17. The top of the first connecting seat 1 and the bottom of the second connecting seat 2 are fixedly connected with a mounting block 12, a through hole 15 is opened in the mounting block 12, a push column 18 is arranged in the through hole 15, one end of the push column 18 is fixedly connected with a threaded column 19, a threaded hole 16 is opened on the top ring 17, and the threaded column 19 is threadedly installed in the threaded hole 16, and the other end of the push column 18 is fixedly installed with a push ring 14 for pushing the push column 18.

[0030] The above design can push the push seat 5 by cooperating with the push column 18, the top ring 17 and the push ring 14, so that the push seat 5 can push the noise reduction sleeve 3 when moving, so that the noise reduction sleeve 3 can fall off from the first connecting seat 1 and the second connecting seat 2, so as to facilitate the replacement of the noise reduction sleeve 3, and the push column 18 can be installed by cooperating with the threaded column 19 and the threaded hole 16.

[0031] When in use, the method of replacing the noise reduction sleeve 3 can be selected according to the needs. When it is convenient to pull out the plug-in block 6 from the pushing seat 5, the plug-in block 6 is pulled out from the pushing seat 5 through the arc block 7. The pushing seat 5 can be pushed by the plug-in block 6, so that when the pushing seat 5 moves in the first connecting seat 1 and the second connecting seat 2, the noise reduction sleeve 3 can be pushed, so that the noise reduction sleeve 3 can be moved out from the first connecting seat 1 and the second connecting seat 2. At this time, the damaged noise reduction sleeve 3 can be detached and replaced;

[0032] If it is inconvenient to withdraw the plug-in block 6 from the pushing seat 5, the push column 18 can be passed through the through hole 15, and the threaded column 19 can be threadedly installed in the threaded hole 16. The push ring 14 cooperates with the push column 18 and the top ring 17 to push the pushing seat 5, so that the pushing seat 5 can push the noise reduction sleeve 3 when moving, so that the noise reduction sleeve 3 can be removed from the first connecting seat 1 and the second connecting seat 2 for removal and replacement.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
