As shown in fig. 1, 2, 3 and 9, a handle assembly according to an embodiment of the present utility model includes a handle 1, a transmission shaft 2, a panel 5, a restoring member 3 and an elastic member 4. One end of the transmission shaft 2 is fixedly connected with the handle 1; the drive shaft 2 is provided with a turning block 21 protruding therefrom, the turning block 21 having at least a first end surface 211 and a second end surface 212 (not shown in the figures). The other end of the transmission shaft 2 is rotationally connected with the face shell 5, and the transmission shaft 2 is arranged in the face shell 5 in a penetrating way. The reset member 3 abuts against the first end surface 211 or the second end surface 212 of the steering block 21, the handle 1 has a first mounting direction (i.e., the mounting direction shown in fig. 3) and a second mounting direction (i.e., the mounting direction shown in fig. 9) which is reversed after rotating a predetermined angle with respect to the face case 5, when the reset member 3 abuts against the first end surface 211, the handle 1 is in the first mounting direction, and when the reset member 3 abuts against the second end surface 212, the handle 1 is in the second mounting direction. One end of the elastic piece 4 is abutted with the face shell 5, and the other end is abutted with the reset piece 3; the elastic member 4 is used for driving the reset member 3 to move so as to reset the handle 1.

In this embodiment, the handle 1 is fixedly connected with the transmission shaft 2, the transmission shaft 2 penetrates through the face shell 5, the face shell 5 is fixedly installed on the door, and a user can drive the door to open or close or drive the door lock to unlock or close through the handle 1. The surface shell 5 is internally provided with a cavity for accommodating components such as the reset piece 3, the elastic piece 4 and the like. In practice, the mounting direction of the handle assembly 100 is different according to the use situation, for example, the direction in which the handle 1 faces when the handle assembly 100 is mounted on the right door may be set to be a first mounting direction, the direction in which the handle 1 faces when the handle assembly 100 is mounted on the left door may be set to be a second mounting direction, and the handle 1 is driven to rotate, so that the handle 1 can be switched between the first mounting direction and the second mounting direction.

In actual use, the handle 1 may have two states, namely a reset state and an unlocked state. The second end surface 212 is located on the other side of the steering block 21 corresponding to the first end surface 211. When the handle 1 is in the first mounting direction or the second mounting direction, the reset member 3 is in contact with the first end surface 211 or the second end surface 212, and when the driving force applied to the handle 1 is released, the handle 1 is not rotated any more, and the handle 1 is in a reset state; the handle 1 is rotated by applying driving force, the transmission shaft 2 rotates along with the rotation, unlocking can be realized, and the door lock is in an unlocking state. Continuing to rotate the handle 1, the reset piece 3 is switched from abutting against the first end face 211 to abutting against the second end face 212, and the handle 1 is switched from the first installation direction to the second installation direction, so that reversing is realized.

The steering block 21 and the transmission shaft 2 may be integrally formed, or may be formed separately, assembled and fixed. The steering block 21 is a member with a curve outline, the reset piece 3 is always abutted against the steering block 21, but the steering block 21 can keep a stable state only when the first end surface 211 or the second end surface 212 of the steering block 21 is abutted against the reset piece 3, and the handle 1 is in the first installation direction or the second installation direction; when the reset piece 3 is abutted with other surfaces of the steering block 21, the steering block 21 cannot realize static balance, and the reset piece 3 can drive the steering block 21 to rotate so as to drive the transmission shaft 2 and the handle 1 to rotate. The elastic member 4 acts to apply a force to the restoring member 3, and when the handle 1 is not in the restoring state, the restoring member 3 is driven to move to restore the handle 1.

In this embodiment, the handle 1 is turned by a preset angle, and then is switched from the first installation direction to the second installation direction, and the preset angle is 180 degrees, which may be other angles set according to the actual application requirement of the handle 1.

In this embodiment, the first mounting direction is 180 degrees from the second mounting direction. The steering block 21 may be designed in a cam structure, and in order to save effort in rotating the handle 1, the third end surface 216 and the fourth end surface 217 of the first protrusion 214 are curved surfaces, or at least the end surfaces of the steering block 21 are smoothly connected to reduce resistance in the rotation process of the drive shaft 2. As shown in fig. 3, when the handle 1 is in the reset state in the first mounting direction, the first end surface 211 abuts against the reset piece 3. As shown in fig. 7, the handle 1 is driven to rotate in a counterclockwise direction (i.e. the arrow direction marked with F in the figure), the transmission shaft 2 rotates by a certain angle, and then the door lock is opened, and at this time, the third end face 216 abuts against the reset piece 3; in this state, the transmission shaft 2 cannot maintain static balance, and after the driving force is released, the handle 1 rotates clockwise (i.e., the direction opposite to the arrow labeled F in the drawing) under the combined action of the elastic member 4 and the reset member 3 until the third end surface 216 abuts against the reset member 3, and the handle 1 returns to the reset state in the first installation direction. As shown in fig. 8, in the critical state in which the third end face 216 of the first protruding portion 214 is switched to the fourth end face 217, at this time, the end face of the first protruding portion 214 furthest from the axis of the transmission shaft 2 is in contact with the reset member 3, and if the handle 1 is continuously driven in the arrow direction of the symbol F in the figure, the fourth end face 217 is in contact with the reset member 3; at this time, the driving force is released, the handle 1 rotates in the counterclockwise direction under the combined action of the elastic member 4 and the restoring member 3 until the second end surface 212 abuts against the restoring member 3, and the handle 1 is restored to the restoring state in the second mounting direction, that is, the state shown in fig. 9, at which time the handle 1 is reversed.

In summary, when the first end surface 211 or the second end surface 212 is abutted against the reset element 3, the handle 1 is in a reset state; when the other end surfaces of the steering block 21 are in contact with the reset piece 3, after the driving force of the handle 1 from the outside is released, the elastic piece 4 and the reset piece 3 jointly act to drive the handle 1 to reset; when the third end surface 216 or the fourth end surface 217 abuts against the restoring member 3, the handle 1 is in an unlocked state.
