The front end of the axial clutch button 17 is exposed from the handle cover plate 12, and the rear end of the axial clutch button 17 is provided with a first clutch connection block 31 which protrudes axially.
Further, the rear end of the clutch base 24 has an axially recessed accommodating groove, and the connection toggle member 25 is disposed at the rear of the clutch base 24 and rotatably connected in the accommodating groove. The front side surface of the connecting toggle piece 25 is provided with a second clutch connecting groove 42 extending axially; a connecting through hole is formed in the side wall of the rear end of the guide groove 240 on the clutch base 24, and the connecting through hole is arranged opposite to the opening of the second clutch connecting groove 42 on the connecting toggle piece 25;
When the axial clutch button 17 is pressed, the bolt 18 slides backwards along the axial direction, and the rear end of the second clutch connection block 32 of the bolt 18 passes through the connection through hole and is inserted into the second clutch connection groove 42 connected with the connection stirring piece 25, so that the bolt 18, the clutch base 24 and the connection stirring piece 25 are connected in a synchronous rotation manner; when the latch return spring 19 elastically returns the latch 18 to the initial position in the axial direction, the rear end of the second clutch connection block 32 of the latch 18 is disengaged from the second clutch connection groove 42 of the connection toggle member 25, so that the clutch base 24 and the connection toggle member 25 can rotate relatively.
Further, a radial threaded hole is further formed in the side surface of the rotating shaft part of the handle seat body 10, and an adjusting screw 9 is connected in the threaded hole in a threaded manner; the positions of the threaded holes and the adjusting screws 9 are opposite to the connecting through holes at the rear ends of the guide grooves 240 in the clutch base 24, so that the adjusting screws 9 can be inserted into the second clutch connecting grooves 42 connected with the connection toggle member 25 after passing through the threaded holes and the connecting through holes.
When the adjusting screw 9 is screwed into the second clutch connecting groove 42 of the connection stirring piece 25, the handle seat body 10 and the connection stirring piece 25 are directly and relatively fixed, and the door opening or locking action can be directly realized through the door handle without operating the radial clutch button 11 and the axial clutch button 17.
When the adjusting screw 9 is located outside the second clutch connection groove 42 but still located in the guide groove 240, the adjusting screw 9 can be blocked at the rear end of the second clutch connection block 32 so that it cannot be inserted into the second clutch connection groove 42; at this time, the axial clutch button 17 cannot be pressed, the function of the axial clutch assembly is disabled, the axial clutch assembly and the connection toggle 25 are permanently in the "off" state, and the door opening or locking operation cannot be performed through the door handle.
When the adjusting screw 9 is not screwed into the second clutch connecting groove 42, the radial clutch button 11 is pressed first, then the axial clutch button 17 is pressed, so that the radial clutch assembly and the axial clutch assembly are both in a 'closed' linkage state, and finally the door can be opened or locked by lifting or pulling down the handle shell.
Specifically, the working principle of the utility model is as follows:
When the radial clutch button 11 is pressed, the lock push lever 15 slides in the radial direction to the maximum stroke; at this time, the first clutch groove 41 of the lock push lever 15 extends to the rear of the axial clutch button 17, and is provided opposite to the first clutch connection block 31. Then, when the axial clutch button 17 is pressed, the first clutch connection block 31 is inserted into the first clutch connection groove 41, so that the handle shell is synchronously and rotatably connected with the axial clutch button 17 through the radial clutch assembly; simultaneously, the bolt 18 slides along the axial direction, so that the second clutch connection block 32 at the rear end of the bolt 18 is inserted into the second clutch connection groove 42 of the connection stirring piece 25, and the connection stirring piece 25 and the axial clutch assembly (the axial clutch button 17, the bolt 18 and the clutch base 24) are relatively fixed in the rotating direction, and can synchronously rotate. When two buttons are sequentially pressed down, the connecting toggle piece 25 can be rotated by lifting or pulling down the handle shell, and the connecting toggle piece 25 is connected with a lock core of a door to realize the action of opening or locking the door. If two buttons are not pressed in sequence, the radial clutch assembly or the axial clutch assembly is in a separated state, the integral structure of the door handle cannot form linkage, and at the moment, even if the handle shell is lifted up or pulled down, the connection stirring piece 25 cannot be rotated, and the door opening or locking action cannot be realized through the connection stirring piece 25.
In addition, the operating state of the door handle can be changed using the adjusting screw 9. Specifically, when the adjusting screw 9 is screwed inward to the second clutch connection groove 42 of the screw-in connection dial 25, the second clutch connection block 32 of the rear end of the plug 18 can be blocked outside the second clutch connection groove 42. At this time, the function of the axial clutch assembly is disabled, and the handle seat 10 and the connection toggle member 25 are relatively fixed through the adjusting screw 9, so that the door can be opened or locked directly through the door handle without any operation on the two buttons.
After the adjustment screw 9 has been screwed slightly outwards, the adjustment screw 9 is disengaged from the second clutch connection slot 42 of the connection dial 25, but still in the guide slot 240 of the clutch base 24. At this time, the adjusting screw 9 still can block the second clutch connection block 32, so that it cannot be inserted into the second clutch connection slot 42, the axial clutch button 17 cannot be pressed, the handle housing is rotationally connected with the clutch base 24 synchronously, but the clutch base 24 and the connection toggle member 25 are in a mutually free state and cannot be rotated synchronously. In this state, no matter how the door handle is operated, the door opening or locking operation cannot be performed.
When the adjusting screw 9 is continuously screwed out until the second clutch connecting groove 42 of the toggle member 25 and the guide groove 240 of the clutch base 24 are disconnected, the door handle is restored to a normal working state, and the door opening or locking action can be realized by sequentially pressing two buttons.
The foregoing examples illustrate only a few embodiments of the utility model and are described in detail herein without thereby limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
