DETAILED DESCRIPTION

[0021] Clearly and completely describe the technical scheme in the embodiments of the utility model with reference to the drawings in the embodiments of the utility model, obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0022] Please refer to Figures 1-4 The utility model provides a technical scheme:

[0023] In the technical scheme, a durable hinge for doors and windows comprises an axial rod 1, a shaft sleeve 2 and hinge plates 3, the hinge plates 3 are two in total, the side walls of the two hinge plates 3 are respectively provided with the axial rod 1 and the shaft sleeve 2, the axial rod 1 is inserted into the shaft sleeve 2 and can rotate in the shaft sleeve 2;

[0024] The axial rod 1 is internally provided with an oil storage cavity 4, the oil storage cavity 4 is filled with lubricating oil 5, the upper wall of the axial rod 1 is provided with a through hole 6, the through hole 6 is communicated with the oil storage cavity 4, a plug rod 7 is inserted into the through hole 6, one end of a supporting rod 8 is installed on the outer side of the plug rod 7, and the other end of the supporting rod 8 is installed with a top ring 9;

[0025] The side wall of the axial rod 1 is provided with an oil outlet hole 10, the oil outlet hole 10 is communicated with the inner cavity of the oil storage cavity 4, and the top ring 9 can block the oil outlet hole 10;

[0026] In the technical scheme, the oil storage cavity 4 is arranged in the axial rod 1, so that when the device produces abnormal noise, the plug rod 7 can be pressed to make the lubricating oil 5 in the oil storage cavity 4 enter the shaft sleeve 2 through the oil outlet hole 10, lubricate the connection between the axial rod 1 and the shaft sleeve 2, reduce the friction between the two, and prolong the service life of the device to achieve the purpose of durability.

[0027] The top ring 9 is always above the oil storage cavity 4 under the action of the spring 11 without pressing the plug rod 7, so that the top ring 9 can block the oil outlet hole 10, and the situation that the lubricating oil 5 flows out of the shaft sleeve 2 due to too much lubricating oil 5 is avoided.

[0028] In some technical schemes, the oil storage cavity 4 is internally provided with a spring 11, one end of the spring 11 is attached to the inner wall of the oil storage cavity 4, and the other end of the spring 11 is attached to the lower wall of the top ring 9.

[0029] In the technical scheme, the spring 11 can provide an upward thrust for the top ring 9, so that the top ring 9 can block the oil outlet hole 10 without external force.

[0030] In some technical solutions, the lower wall of the shaft rod 1 is provided with a threaded hole 12, and a positioning bolt 13 is rotatably installed in the threaded hole 12. The positioning bolt 13 can be attached to the lower wall of the shaft sleeve 2. The outer sides of the upper and lower ends of the shaft rod 1 are sleeved with a first sealing ring 14 and a second sealing ring 15. The two first sealing rings 14 are respectively attached to the upper wall and the lower wall of the shaft sleeve 2. The two second sealing rings 15 are inserted and installed inside the shaft sleeve 2.

[0031] In this technical solution, by setting the threaded hole 12 and the positioning bolt 13 below the shaft rod 1, the device can be easily assembled.

[0032] The setting of the first sealing ring 14 and the second sealing ring 15 can make the connection between the shaft rod 1 and the shaft sleeve 2 sealed after the shaft rod 1 is inserted into the shaft sleeve 2, thereby avoiding the leakage of lubricating oil 5 when the lubricating oil 5 is injected.

[0033] In some technical solutions, the side wall of the hinge plate 3 is provided with a mounting hole 16, and a screw 17 is inserted and installed in the mounting hole 16. The hinge plate 3 is connected to the outer door window through the screw 17.

[0034] In some technical solutions, the end of the plug rod 7 located outside the shaft rod 1 is provided with a pressing block 18, and a sealing gasket 19 is attached to the lower wall of the pressing block 18. The sealing gasket 19 can be attached to the inner wall of the through hole 6.

[0035] In this technical solution, the sealing gasket 19 can ensure that the lubricating oil 5 in the oil storage cavity 4 does not leak out through the through hole 6. In addition, when the device is installed on the outer door window, the end of the shaft rod 1 provided with the pressing block 18 needs to be upward.

[0036] In some technical solutions, the side wall of the shaft rod 1 located inside the shaft sleeve 2 is provided with an annular groove 20, and the side wall of the shaft rod 1 is provided with an oil guide groove 21. The oil guide groove 21 penetrates through two adjacent annular grooves 20.

[0037] In this technical solution, through the cooperation of the annular groove 20 and the oil guide groove 21, the lubricating oil 5 can be distributed more evenly after entering the connection between the shaft rod 1 and the shaft sleeve 2, thereby improving the lubricating effect.

[0038] Working principle: when the device is used for a period of time, due to the decrease of lubricating oil 5 between the shaft rod 1 and the shaft sleeve 2, when the rotating hinge plate 3 is rotated, the device will produce abnormal sound due to the friction between the shaft rod 1 and the shaft sleeve 2. At this time, the pressing block 18 above the plug rod 7 can be pressed to make the top ring 9 move downward, and the oil outlet hole 10 is exposed. At this time, the lubricating oil 5 in the oil storage cavity 4 enters the inside of the shaft sleeve 2 through the oil outlet hole 10, lubricates the connection between the shaft rod 1 and the shaft sleeve 2, reduces the friction between the two, thereby prolonging the service life of the device and achieving the purpose of durability.
