DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] Please refer to Figures 1-3 The present application provides a technical solution:

[0022] In the technical solution, a double-tooth eccentric handle includes a handle seat 1 and a handle 2. The handle seat 1 is installed on an external window frame. The handle 2 is rotatably installed on the side wall of the handle seat 1. One end of the drive rod 3 is installed on the side wall of the handle 2. The other end of the drive rod 3 is inserted into the handle seat 1.

[0023] A transmission mechanism 4 is installed in the handle seat 1. A square steel strip 5 is inserted into the side wall of the handle seat 1. The square steel strip 5 and the drive rod 3 are connected with the transmission mechanism 4.

[0024] A lubricating mechanism 6 is installed in the handle seat 1. The lubricating mechanism 6 includes an oil storage bag 61, a button 62 and a spring 63. The oil storage bag 61 is attached to the inner side wall of the handle seat 1. An oil outlet hole 7 is formed in the side wall of the oil storage bag 61. A sliding groove 8 is formed in the side wall of the handle seat 1. The button 62 is slidingly installed in the sliding groove 8. The spring 63 is installed in the sliding groove 8 and attached to the side wall of the button 62.

[0025] In this technical solution, the lubricating mechanism 6 is provided to lubricate the main transmission tooth 41 and the auxiliary transmission tooth 42 in the transmission mechanism 4, so that the rotation of the two is smoother, and the abnormal noise during the rotation of the handle 2 after long-term use is avoided.

[0026] When lubrication is needed, the button 62 is pressed to extrude the oil storage bag 61, so that the lubricating oil in the oil storage bag 61 is sprayed out through the oil outlet hole 7 and falls on the transmission mechanism 4, thereby achieving the purpose of lubricating the transmission mechanism 4.

[0027] Because the oil outlet hole 7 is small, the lubricating oil will not flow out from the oil outlet hole 7 under the self tension of the lubricating oil without extruding the oil storage bag 61, and the lubricating oil can be sprayed from the oil outlet hole 7 only after the oil storage bag 61 is extruded.

[0028] In some technical solutions, the transmission mechanism 4 comprises a main transmission gear 41, a secondary transmission gear 42 and a slot 43. The main transmission gear 41 and the secondary transmission gear 42 are both rotatably installed in the handle seat 1 and are in meshing connection. The middle part of the sidewall of the main transmission gear 41 is provided with the slot 43, and the drive rod 3 is inserted and installed in the slot 43. The secondary transmission gear 42 is sleeved on the outer side of the square steel bar 5.

[0029] In this technical solution, through the cooperation of the main transmission gear 41 and the secondary transmission gear 42, the device forms an eccentric structure, so that when the handle 2 is rotated, the square steel bar 5 can be rotated under the cooperation of the main transmission gear 41 and the secondary transmission gear 42, thereby driving the steel bar in the external window frame lock box to move.

[0030] Because the device is an eccentric structure, it can be applied not only to doors and windows with normal frames but also to doors and windows with narrow frames, thereby improving the applicability of the device.

[0031] In some technical solutions, the sidewall of the handle 2 is provided with an annular sliding groove 9, and the annular sliding groove 9 is slidably installed with a connecting ring 10. The sidewall of the handle seat 1 is provided with a connecting groove 11, and the connecting ring 10 can be inserted and installed in the connecting groove 11. The sidewall of the handle seat 1 is provided with a threaded hole 12, which is in communication with the connecting groove 11. The threaded hole 12 is rotatably installed with a screw rod 13. The sidewall of the connecting ring 10 is provided with a clamping groove 14, and the screw rod 13 can be inserted into the clamping groove 14.

[0032] In this technical solution, the handle 2 is installed on the handle seat 1 through the cooperation of the connecting ring 10 and the connecting groove 11, and then the installation of the handle 2 is completed by inserting the screw rod 13 into the clamping groove 14.

[0033] In some technical solutions, one end of an oil injection pipe 15 is inserted and installed in the sidewall of the oil storage bag 61, the other end of the oil injection pipe 15 penetrates through the sidewall of the handle seat 1, and the end of the oil injection pipe 15 located outside the handle seat 1 is inserted and installed with a plug 16.

[0034] In this technical solution, the oil injection pipe 15 is arranged to facilitate the filling of lubricating oil into the oil storage bag 61.

[0035] In some technical solutions, the lower part of the inner cavity of the handle seat 1 is attached and installed with an oil absorption cotton 17.

[0036] In the technical scheme, the excess lubricating oil in the handle seat 1 can be absorbed by the oil absorbing cotton 17, so that the oil leakage of the device is avoided.

[0037] In some technical schemes, the side wall of the handle seat 1 is provided with a connecting hole 18, and a bolt 19 is inserted and installed in the connecting hole 18, and the handle seat 1 is installed on the external window frame through the bolt 19.

[0038] Working principle: the device is installed on the external window frame through the bolt 19, and the handle 2 is rotated, so that the square steel strip 5 is rotated under the cooperation of the main transmission teeth 41 and the auxiliary transmission teeth 42, so as to drive the steel strip in the external window frame lock box to move, so as to achieve the unlocking and locking operation of the door and window.

[0039] After the device is used for a period of time, the main transmission teeth 41 and the auxiliary transmission teeth 42 are prone to insufficient lubrication, which causes abnormal noise. At this time, the button 62 can be pressed to extrude the oil storage bag 61, so that the lubricating oil in the oil storage bag 61 is sprayed out through the oil outlet hole 7 and falls on the transmission mechanism 4, so as to achieve the purpose of lubricating the transmission mechanism 4.

[0040] It should be noted that, in the present text, the relationship terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between the entities or operations. Moreover, the terms "include", "contain" or any other variants thereof are intended to cover non-exclusive inclusion, so that the process, method, article or equipment including a series of elements not only includes those elements, but also includes other elements not explicitly listed or inherent to such process, method, article or equipment.

[0041] Although the utility model has been described above with reference to the embodiments, various improvements can be made and equivalent parts can be replaced without departing from the scope of the utility model. In particular, as long as there is no structural conflict, the features in the embodiments disclosed by the utility model can be combined in any way, and the combinations are not described exhaustively in the specification only for the purpose of saving space and resources.
