A locking groove 8 adapted to the locking boss 7 is provided on the inner peripheral wall of the first chamber 3;

[0042] The rotating rod 9, one end of the rotating rod 9 is installed in the installation hole 6;

[0043] The second pressing member 10 is located in the second chamber 4 and is circumferentially movably connected to the first pressing member 5;

[0044] Wherein, a through hole for pressing the second pressing member 10 is provided on the second handle. When the second pressing member 10 is pressed, the second pressing member 10 drives the first pressing member 5 to axially move, and at this time, the locking boss 7 is separated from the locking groove 8.

[0045] The door lock handle is the main operating component of the door lock, for the user to hold and rotate to control the opening and closing of the door lock. The door lock handle includes a first handle body 1 and a second handle body 2 that are perpendicular to each other. Such a design makes the overall structure of the door lock handle in an "L" shape, and the "L" shape design is convenient for the user to hold and apply force. One end of the first handle body 1 abuts against the door lock, and the first handle body 1 and the second handle body 2 can be integrally formed.

[0046] The first chamber 3 and the second chamber 4 provide installation spaces for components. The first chamber 3 axially penetrates the first handle body 1 and is connected to the second chamber 4 in the second handle body 2.

[0047] The first pressing member 5 connects and fixes one end of the rotating rod 9, and at the same time provides a pressing block 19 to lock the rotating rod 9. The first pressing member 5 can be cylindrical. The installation hole 6 at the bottom end is used to accommodate and fix the rotating rod 9, and the shape of the installation hole 6 is adapted to the rotating rod 9. The locking boss 7 is used to cooperate with the locking groove 8 in the first chamber 3 to realize the locking and separation of the first pressing member 5. The locking boss 7 can be fixed on the outer periphery of the middle part of the first pressing member 5 through welding or an integral design. The locking boss 7 and the locking groove 8 are both fan-shaped and adapted to each other. The fan-shaped structure has high stability and bearing capacity in mechanics. Through the close fitting of the fan-shaped surfaces, stress can be more effectively transmitted and dispersed, thereby enhancing the firmness of the connection.

[0048] The rotating rod 9 drives the locking mechanism inside the door lock by rotation to achieve the locking and separation of the door lock. The rotating rod 9 can be a linear cube structure, and the cube structure has a stable transmission efficiency. One end of the rotating rod 9 extends into the installation hole 6 and is connected to the first pressing member 5, and the other end is connected to the locking mechanism inside the door lock.

[0049] The second pressing member 10 drives the first pressing member 5 to disengage from the locking groove 8 by applying a force towards the inside of the second handle body 2, so as to achieve the purpose of being unable to control the door lock. The second pressing member 10 is arranged in the second cavity through the through hole on the second handle and is circumferentially movably connected to the first pressing member 5.

[0050] Embodiment 2:

[0051] This embodiment provides a door lock handle. In addition to including the technical solutions of the above embodiment, it also has the following technical features.

[0052] The second pressing member 10 and the first pressing member 5 are circumferentially movably connected through a moving mechanism;

[0053] The moving mechanism includes a transmission boss 11 and a pressing section 12. The transmission boss 11 is arranged on the outer peripheral wall of the first pressing member 5, and a transmission groove 13 adapted to the transmission boss 11 is provided on the second pressing member 10. The pressing section 12 is arranged on the second pressing member 10 and is located in the pressing hole, and the pressing section 12 is perpendicular to the second pressing member 10.

[0054] The transmission boss 11 is used to receive the axially moving force transmitted by the second pressing member 10 to drive the first pressing member 5 and realize the axial movement of the first pressing member 5. The transmission boss 11 can be in an annular shape and can be fixed on the outer peripheral wall of the first pressing member 5 through welding or an integral design. The second pressing member 10 can be in a plate-like structure, and an arc groove adapted to the column in the first pressing member 5 is provided at the front, so that the arc groove can be in close contact with the column, and a transmission groove 13 adapted to the above-mentioned transmission boss 11 is also provided at the front. A pressing section 12 perpendicular to the second pressing member 10 and located in the pressing hole is provided at the tail of the second pressing member 10. The pressing section 12 can be fixed on the tail of the second pressing member 10 through welding or an integral design, and the pressing section 12 can be a cube or a cylinder adapted to the through hole.

[0055] Wherein, when the pressing section 12 in the second pressing member 10 is pressed, through the cooperation of the transmission boss 11 and the transmission groove 13, the axial movement of the first pressing member 5 is driven, so that the locking boss 7 on the first pressing member 5 disengages from the locking groove 8 on the inner wall of the first chamber 3, so as to achieve the purpose that the door lock cannot be opened even if the door lock handle is rotated.

[0056] Embodiment 3:

[0057] This embodiment provides a door lock handle, which, in addition to including the technical solutions of the above embodiment, further has the following technical features.

[0059] Wherein, one end of the square rod portion 14 is installed in the installation hole 6 in the rotating rod 9, and the other end of the square rod portion 14 is installed in the door lock.

[0060] The square rod portion 14 can provide higher anti-torsion and anti-bending strength. When the square cross-section is subjected to an external force, due to the existence of its four corner points, it can better disperse the stress, thereby enhancing the overall stability. The round rod portion 15 helps to reduce friction and resistance during the transmission process. The circular cross-section has better sliding performance, making the square rod rotate more smoothly inside the lock body, reducing wear and noise caused by friction. Therefore, compared with the common all-square rod design in the door lock system, the design combining the square rod portion 14 and the round rod portion 15 improves the transmission efficiency and service life of the door lock handle. At the same time, the design adopted in this embodiment reduces the use of materials compared with the all-square rod design, thereby reducing costs.
