[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1-5 As shown, a detachable door handle mechanism includes a door handle body, which includes a handle mechanism 1 and a lock cylinder mechanism 2. The handle mechanism 1 and the lock cylinder mechanism 2 are detached, with the lock cylinder mechanism 2 located below the handle mechanism 1. The handle mechanism 1 includes a first fixed seat 3, a second fixed seat 4, an outer handle 5, and an inner handle 6. The outer handle 5 is movably mounted on the first fixed seat 3, and the inner handle 6 is movably mounted on the second fixed seat 4. A main shaft 7 is movably mounted on both the first fixed seat 3 and the second fixed seat 4. The main shaft 7 is movably connected to the first fixed seat 3 and the second fixed seat 4 via a torsion spring 8. One end of the outer handle 5 and the inner handle 6 is connected to the main shaft 7. The lock cylinder mechanism 2 includes a third fixed seat 9 and a fourth fixed seat 10, which are respectively fixed on both sides of the door lock cylinder hole by screws 11.

[0027] In this embodiment, the handle mechanism 1 and the lock cylinder mechanism 2 can be selectively installed on the window profile according to the user's needs. They can be installed together or one of them can be selected for installation. Before installing the handle mechanism 1 and the lock cylinder mechanism 2, handle holes and lock cylinder holes need to be set on the window profile. The handle mechanism 1 is installed in the handle hole and the lock cylinder mechanism 2 is installed in the lock cylinder hole.

[0028] Furthermore, a square steel 12 is installed between the first fixed seat 3 and the second fixed seat 4. The two ends of the square steel 12 are respectively connected to the main shaft 7 on the outer handle 5 and the inner handle 6 for transmission. The main shaft 7 is provided with a slot that cooperates with the square steel 12.

[0029] In this embodiment, the outer handle 5 and the inner handle 6 of the handle mechanism 1 are linked by the main shaft 7 and the square steel 12, and the square steel 12 can drive other components inside the window profile.

[0030] Furthermore, the torsion spring 8 is installed in the limiting groove of the main shaft 7, and the other end of the torsion spring 8 is engaged with the corresponding first fixed seat 3 and second fixed seat 4.

[0031] In this embodiment, the torsion spring 8 can provide the torque for the spindle 7 to reset, so that the handle can be reset under the action of the torsion spring 8 after the handle is released.

[0032] Furthermore, a cross-slot countersunk screw 13 is installed below the first fixing seat 3 and the second fixing seat 4. The cross-slot countersunk screw 13 is installed on the mounting hole of the fixing seat, and the first fixing seat 3 and the second fixing seat 4 are fixedly connected by the cross-slot countersunk screw 13.

[0033] In this embodiment, the cross-head countersunk screw 13 is used to connect the first fixing seat 3 and the second fixing seat 4, so that the connection between the first fixing seat 3 and the second fixing seat 4 is stable.

[0034] Furthermore, a No. 2 screw 14 is installed above the first fixing seat 3 and the second fixing seat 4, and the first fixing seat 3 and the second fixing seat 4 are fixedly installed on the door by the No. 2 screw 14.

[0035] In this embodiment, screw 14 is used to fix the upper part of the first fixing seat 3 and the second fixing seat 4 to prevent the fixing from loosening.

[0036] Furthermore, a handle panel 15 is fixedly installed on the outer side of the first fixing seat 3 and the second fixing seat 4, and a fixing hole is provided on the handle panel 15.

[0037] In this embodiment, the handle panel 15 is used to cover the connection point, improving the aesthetics of the door handle.

[0038] Furthermore, a connecting hole 16 is provided inside one end of the outer handle 5 and the inner handle 6, and the other end of the spindle 7 is installed in the connecting hole 16 of the outer handle 5 and the inner handle 6, and the spindle 7 is fixedly connected to the connecting hole 16 by a general-purpose No. 3 screw 17.

[0039] In this embodiment, the other end of the spindle 7 is connected to the handle through the connecting hole 16, and the spindle 7 will rotate synchronously when the handle is turned.

[0040] Furthermore, a large spring 18 and a handle washer 19 are provided on the outside of the connecting hole 16. One end of the handle washer 19 is installed in the hole of the handle panel 15 and the fixing seat, and the large spring 18 is embedded in the slot of the fixing seat.

[0041] In this embodiment, the large spring 18 is used to improve the stability of the outer handle 5 and the inner handle 6, making the handles less prone to loosening.

[0042] Furthermore, both the third fixing seat 9 and the fourth fixing seat 10 are provided with lock cylinder holes 20.

[0043] Specifically, a lock cylinder panel 21 is installed on the third fixing seat 9 and the fourth fixing seat 10, and the lock cylinder panel 21 is provided with an external lock cylinder hole corresponding to the lock cylinder hole 20.

[0044] In this embodiment, the lock cylinder hole 20 is used to install the lock cylinder, which can facilitate fixing the position of the lock cylinder.

[0045] The working principle of this utility model is as follows:

[0046] This utility model allows for the selective installation of a handle mechanism 1 and a lock cylinder mechanism 2 on window profiles according to user needs. They can be installed together or one can be selected for installation. Before installing the handle mechanism 1 and lock cylinder mechanism 2, handle holes and lock cylinder holes need to be set on the window profile. The handle mechanism 1 is installed in the handle hole, and the lock cylinder mechanism 2 is installed in the lock cylinder hole. The outer handle 5 and inner handle 6 of the handle mechanism 1 are linked through a main shaft 7 and a square steel 12. Simultaneously, the square steel 12 can drive other components inside the window profile. The lock cylinder mechanism 2 has a lock cylinder installed between the third fixed seat 9 and the fourth fixed seat 10, allowing the lock cylinder to have its own hole. This prevents interference between the handle mechanism 1 and the lock cylinder mechanism 2. This separate design is compact and elegant. Users can decide whether to install a locking structure based on their needs. The ingenious structure breaks away from the traditional door handle structure, separating the handle transmission structure from the lock cylinder installation structure, providing users with two options while maintaining aesthetics.
