Wherein the direction indicated by the dotted arrow in fig. 3 is the first direction.

The handle structure 10 comprises a mounting body 12, a first transmission mechanism 13, an actuating mechanism 15 and a safety mechanism 17, wherein the first transmission mechanism 13, the actuating mechanism 15 and the safety mechanism 17 are mounted on the mounting body 12, the first transmission mechanism 13 is used for driving the actuating mechanism 15 to move under the drive of a user, the actuating mechanism 15 is used for being connected with a locking mechanism 30 so as to move under the drive of the first transmission mechanism 13 and drive the locking mechanism 30 to unlock so as to open the sliding door 100, the safety mechanism 17 can be switched into a working state or a safety state under the operation of the user, wherein in the working state, the first transmission mechanism 13 is connected with the actuating mechanism 15, in the safety state, the first east-out mechanism is disconnected with the actuating mechanism 15, and further, the situation of mistaken opening is avoided, and by disconnecting the first transmission mechanism 13 and the actuating mechanism 15, so that the handle is not easily broken even if the operator rotates the handle without paying attention to the safety state.

Wherein, the actuator 15 may include a stopping swing arm 151 and a manipulating swing arm 152, the manipulating swing arm 152 is rotatably connected to the mounting body 12, the stopping swing arm 151 is also rotatably connected to the mounting body 12, the manipulating swing arm 152 is used for connecting with the locking mechanism 30, and the manipulating swing arm 152 is used for unlocking the locking mechanism 30 of the sliding door 100 when rotating to the first position 121 along the first direction;

the first transmission mechanism 13 includes a first handle 131, and the first handle 131 and the safety mechanism 17 are both connected to the mounting body 12, wherein the safety mechanism 17 can be switched to a safety state or an operating state by an external force, and in the operating state, the safety mechanism 17 connects the stopping swing arm 151 and the operating swing arm 152, in other words, the stopping swing arm 151 and the operating swing arm 152 are connected by the safety mechanism 17, and in the safety state, the safety mechanism 17 disconnects the stopping swing arm 151 and the operating swing arm 152, in other words, the safety mechanism 17 releases the connection between the stopping swing arm 151 and the operating swing arm 152 by a user's operation.

The first handle 131 is further connected to the stopping swing arm 151, and a user can operate the first handle 131 to make the first handle 131 drive the stopping swing arm 151 to rotate under the action of an external force, and drive the operating swing arm 152 to rotate the first position 121 along the first direction through the stopping swing arm 151 in a working state.

In this way, by providing the safety mechanism 17 capable of connecting the stopping swing arm 151 and the operating swing arm 152 and releasing the connection between the stopping swing arm 151 and the operating swing arm 152, in the operating state, the operator can drive the operating swing arm 152 to move and further unlock the lock mechanism 30 by sequentially passing through the first handle 131, the stopping swing arm 151, and the safety mechanism 17, in the safety state, the safety mechanism 17 disconnects the connection between the stopping swing arm 151 and the operating swing arm 152, so that the operator can rotate the first handle 131, and even if the operator rotates the first handle 131 without paying attention to the safety state, the first handle 131 is not easily broken.

Referring to fig. 3, 4 and 5, the operating swing arm 152 may be formed with a first stop hole 1522, and correspondingly, the stop swing arm 151 may also be formed with a second stop hole 1512, and the safety mechanism 17 may include a stop pin 171, and the safety mechanism 17 may be switched to the working state by the process that the stop pin 171 enters the first stop hole 1522 and the second stop hole 1512 simultaneously under the external force to connect the stop swing arm 151 and the operating swing arm 152 through the stop pin 171, and the process that the safety mechanism 17 is switched to the safety state is that the stop pin 171 exits the first stop hole 1522 and the second stop hole 1512 simultaneously under the external force to disconnect the stop swing arm 151 and the operating swing arm 152, so that the user may rotate the first handle 131 under the safety state.

In this way, the stop swing arm 151 and the operating swing arm 152 are connected by placing the stop pin 171 into the first stop hole 1522 and the second stop hole 1512, and the stop swing arm 151 and the operating swing arm 152 are disconnected by removing the stop pin 171 from the first stop hole 1522 and the second stop hole 1512.

Further, the actuator 15 may further include a rotation pin 153, and the stopping swing arm 151 and the operating swing arm 152 are both rotatably connected to the mounting body 12 by the rotation pin 153, that is, the rotation pin 153 is mounted to the mounting body 12, and the stopping swing arm 151 and the operating swing arm 152 are both rotatably connected to the rotation pin 153.

The operating swing arm 152 may further have a first sliding hole 1523 communicated with the first stopping hole 1522, and the first stopping hole 1522 and the first sliding hole 1523 are both disposed in a manner of extending along a length direction of the operating swing arm 152, or the first stopping hole 1522 and the first sliding hole 1523 are two sections of a strip-shaped hole, and the second stopping hole 1512 is disposed in a manner of extending along a length direction of the stopping swing arm 151, and the stopping swing arm 151 may further have a second sliding hole 1513 communicated with the second stopping hole 1512, where the second sliding hole 1513 is an arc-shaped strip hole whose axis is the rotating pin 153, and the second sliding hole 1513 is an arc-shaped strip hole whose center is the rotating pin 153.

The stop pin 171 can enter the first sliding hole 1523 through the first stop hole 1522 under the action of an external force, and simultaneously enter the second stop hole 1512 through the second stop hole 1512, so that the safety mechanism 17 is in a safety state, and when the stop swing arm 151 rotates under the driving of the first transmission mechanism 13, the stop pin 171 slides in the second sliding hole 1513, so as to disconnect the stop swing arm 151 and the operation swing arm 152. In other words, the first stopper hole 1522 and the second stopper hole 1512 are overlapped, the first sliding hole 1523 and the second sliding hole 1513 are partially overlapped, when the stopper pin 171 is located in the first stopper hole 1522 and the second stopper hole 1512, since the first stopper hole 1522 and the second stopper hole 1512 are respectively extended along the length direction of the manipulation swing arm 152 and the stopper swing arm 151, when the stopper swing arm 151 rotates relative to the mounting body 12, the sidewall of the second stopper hole 1512 will push the stopper pin 171, and the stopper pin 171 can push the manipulation swing arm 152 again to realize the connection between the manipulation swing arm 152 and the stopper swing arm 151, and when in the safety state, the stopper pin 171 is located in the second sliding hole 1513 and the first sliding hole 1523, since the second sliding hole 1513 is an arc-shaped bar hole and its axis is the rotating pin 153, when the stopper swing arm 151 rotates around the rotating pin 153, the stopper pin 171 slides in the second sliding hole 1513, the effect of the rotation of the stop swing arm 151, but not the rotation of the operating swing arm 152, is achieved.

In this way, the connection between the stopping swing arm 151 and the operating swing arm 152 is maintained or released by moving the stopping pin 171 in the first stopping hole 1522 or the first sliding hole 1523, which is simple, has a short stroke, and is convenient for the user to operate.

So that the stopping swing arm 151 brings the operating swing arm 152 to return to the second state.

Referring to fig. 3, the actuator 15 may further include a restoring elastic member 155, the restoring elastic member 155 is connected to the stopping swing arm 151, the restoring elastic member 155 is elastic, the stopping swing arm 151 is configured to have a tendency to rotate in the second direction under the elastic force of the restoring elastic member 155, and after the user pulls the first handle 131 to rotate the stopping swing arm 151 in the first direction and the user does not operate the first handle 131, the restoring elastic member 155 drives the stopping swing arm 151 to rotate in the second direction to rotate the operating swing arm 152 to the second position 122. So that the manipulation swing arm 152 is restored to the second state.

Further, the first transmission mechanism 13 may further include a first transmission swing arm 132, the first transmission swing arm 132 is rotatably connected to the mounting body 12 and connected to the first handle 131, and one end of the transmission swing arm is abutted to the stopping swing arm 151, when the user operates the first handle 131, the first transmission swing arm 132 may be driven to push the stopping swing arm 151 to rotate along the first direction, so that the first transmission mechanism 13 is connected to the stopping swing arm 151 in an abutting manner, and the stopping swing arm 151 does not drive the first transmission swing arm 132 to move under the action of other forces along the first direction, even if the user operates the first handle 131 at the same time, the first handle 131 is not easily damaged.

Referring to fig. 3, fig. 4, fig. 9 and fig. 10, fig. 9 is a schematic structural diagram of a second driving swing arm 191 of the handle structure 10 according to the embodiment of the present invention. Fig. 10 is a schematic structural diagram of the second driving swing arm 191 of the handle structure 10 according to another view angle.

The handle structure 10 may further include a second transmission mechanism (not shown), the second transmission mechanism may include a second handle (not shown) and a second transmission swing arm 191, the second transmission swing arm 191 is rotatably connected to the rotation pin 153, the control swing arm 152 may further have a third sliding hole 1525, the third sliding hole 1525 is an arc-shaped hole whose axis is the rotation pin 153, the second transmission swing arm 191 is provided with a transmission protrusion 1912, the transmission protrusion 1912 is located in the third sliding hole 1525 to connect the second transmission swing arm 191 and the control swing arm 152, and when the user operates the second handle, the second transmission swing arm 191 is configured to rotate in the first direction under the driving of the second handle, and the transmission protrusion 1912 abuts against one end of the third sliding hole 1525 to drive the control swing arm 152 to rotate in the first direction, and when the operator drives the second transmission swing arm 191 to rotate in the second direction through the second handle, the drive boss 1912 slides in the third slide hole 1525.

In this way, the second driving swing arm 191 independent of the stopping swing arm 151 drives the operating swing arm 152 to rotate, so that even when the safety mechanism 17 is in the safety state, the second handle can drive the operating swing arm 152 to rotate independently, and the third sliding hole 1525 which is an arc-shaped hole and has the axis of the rotating pin 153 is provided, so that the second driving swing arm 191 can only drive the operating swing arm 152 to rotate in the first direction, and the second driving swing arm 191 cannot drive the operating swing arm 152 to rotate in the second direction when rotating in the second direction opposite to the first direction, and the rotation of the operating swing arm 152 to the second position 122 is not affected.

Further, the stopping swing arm 151 may be convexly provided with a first linkage block 1515, the first linkage block 1515 abuts against the second driving swing arm 191, and the first linkage block 1515 can push the second driving swing arm 191 to rotate when the stopping swing arm 151 rotates along the second direction, so as to drive the second driving swing arm 191 to reset through the stopping swing arm 151. In other words, when the first linkage block 1515 drives the second transmission swing arm 191 to rotate along the second direction, and the driving manner is pushing, on the contrary, when the second transmission swing arm 191 rotates along the second direction, the second transmission swing arm 191 does not drive the stopping swing arm 151 to rotate, and the second transmission swing arm 191 can drive the stopping swing arm 151 to rotate along the first direction through the first linkage block 1515 when rotating along the first direction, so that the second transmission swing arm 191 can only operate the stopping swing arm 151 in one direction, and the influence of the second transmission swing arm 191 on the movement of the stopping swing arm 151 is reduced.

Correspondingly, one end of the first transmission swing arm 132 of the first transmission mechanism 13 is abutted against the stopping swing arm 151, and only the stopping swing arm 151 can be driven to rotate along the first direction, so that the influence of the first transmission swing arm 132 on the movement of the stopping swing arm 151 is reduced.

The working principle of the handle structure 10 provided by the embodiment of the invention is as follows:

in the process of switching the safety mechanism 17 to the safety state, the user pushes the safety push block 173, and moves in the second safety connection hole 1722 of the safety swing arm 172 through the paddle protrusion 1732 of the connection paddle 1731 to drive the safety swing arm 172 to rotate, so that the stop pin 171 penetrating through the first safety connection hole 1721 simultaneously enters the first stop hole 2 and the second stop hole 1512 under the rotation action of the safety swing arm 172, at this time, the user can drive the first transmission swing arm 132 through the first handle 131 and push the stop swing arm 151 to rotate along the first direction through the first transmission swing arm 132, the stop swing arm 151 drives the operation swing arm 152 to have the first position 121 to rotate along the first direction to the second position 122 through the stop pin 171 located in the first stop hole 1522 and the second stop hole 1512 to drive the locking mechanism 30 to unlock, and because the second transmission swing arm 191 is connected with the operation swing arm 152 through the transmission protrusion 1912 located in the third sliding hole 1525, when the operating swing arm 152 rotates along the first direction, the operating swing arm 152 is not driven to rotate, and because the stopping swing arm 151 abuts against one end of the second transmission swing arm 191 along the first direction through the first linkage block 1515, the stopping swing arm 151 does not drive the second transmission swing arm 191 to rotate when rotating along the first direction.

When the safety mechanism 17 is switched to the working state, the user pushes the safety push block 173, and the second safety connection hole 1722 on the safety swing arm 172 moves through the paddle protrusion 1732 on the connection paddle 1731 to drive the safety swing arm 172 to rotate, so that the stop pin 171 penetrating through the first safety connection hole 1721 simultaneously enters the first sliding hole 1523 and the second sliding hole 1513 under the rotation action of the safety swing arm 172, at this time, the user can rotate the first handle 131, but when the first handle 131 drives the first transmission swing arm 132 and pushes the stop swing arm 151 to rotate along the first direction through the first transmission swing arm 132, the stop pin 171 slides in the second sliding hole 1513 relative to the stop swing arm 151, so that the handle is rotated without the user noticing the safety state, and the handle is not easily damaged.
