[0031] In a specific implementation, the lock 20 includes a lock fixing frame 21 and a blocking piece 22. The lock fixing frame 21 is fixedly installed on the door frame, and the blocking piece 22 is fixedly installed in the lock fixing frame 21. The lock fixing frame 21 and the blocking piece 22 surround and form a lock cavity 23.

[0032] During the specific implementation, the lock tongue 12 corresponds to the lock cavity 23. When the handle 11 drives the lock tongue 12 to rotate, when the lock tongue 12 is located outside the lock cavity 23, that is, the lock tongue 12 is not fully inserted into the lock cavity 23, in this state, the lock tongue 12 does not contact the baffle 22 in the lock cavity 23, and the two parts of the door are not locked, so that the handle lock system is in an unlocked state. When the user rotates or pushes the handle 11, the handle 11 drives the lock tongue 12 to rotate, so that the lock tongue 12 enters the lock cavity 23. After the lock tongue 12 enters the lock cavity 23, it cooperates closely with the baffle 22 to form a firmly locked state. At this time, the lock tongue 12 is fixed in the lock cavity 23, so that the handle lock system is in a locked state.

[0033] During specific implementation, the lock body 10 also includes a special-shaped transmission shaft 14 and a screw 15. A connecting through hole 131 is provided on the surface of the base plate 13, a first positioning through hole 121 is provided on the surface of the lock tongue 12, a handle connecting portion 111 is provided at one end of the handle 11, and a second positioning through hole 112 is provided in the middle of the handle connecting portion 111.

When in use, the design of the polygonal positioning rod 142a and the polygonal positioning through-hole ensures that the handle 11 can drive the lock tongue 12 to rotate, thereby avoiding loosening of the lock body or poor operation due to errors. The cooperation between the threaded rod 142b and the screw 15 can not only stabilize the connection of the transmission shaft, but also enhance the durability of the lock body structure, thereby avoiding loosening or falling off due to long-term wear or external force during use.

[0035] In the specific implementation, the lock fixing frame 21 is a U-shaped structure, and a baffle connecting portion 211 is provided on the upper part of the lock fixing frame 21. The baffle 22 is arranged on the inner surface of the baffle connecting portion 211. A first fixing through-hole 212 is opened on the surface of the baffle connecting portion 211, and a second fixing through-hole 221 is opened on the surface of the baffle 22. The first fixing through-hole 212 corresponds to the second fixing through-hole 221, and the rivet 30 passes through the first fixing through-hole 212 and the second fixing through-hole 221 to connect and fix, so that the baffle 22 is fixedly installed in the lock fixing frame 21. A lock tongue locking portion 122 is provided on one side of the tongue 12, and the lock tongue locking portion 122 corresponds to the lock cavity 23. When in use, the handle 11 drives the lock tongue 12 to rotate. When the lock tongue locking portion 122 is located outside the lock cavity 23, the lock tongue locking portion 122 does not contact the baffle 22 in the lock cavity 23, and the handle lock system is in an unlocked state. The handle 11 drives the lock tongue 12 to rotate. When the lock tongue locking portion 122 is located in the lock cavity 23, the lock tongue locking portion 122 enters the lock cavity 23 and closely cooperates with the baffle 22, and the handle lock system is in a locked state.

[0036] In a specific implementation, a catheter mounting groove 113 is symmetrically provided on both sides of the second positioning through hole 112, a catheter 16 is connected to the catheter mounting groove 113, a spring 161 is connected to the catheter 16, and a ball 162 is provided at the end of the spring 161.

The spring 161 pushes the ball 162 to form a limiting connection with the limiting hole 132. During use, when the user turns the handle, the ball 162 will move along the path of the limiting hole 132. Every time the ball 162 enters the next limiting hole 132, the user will feel a certain operational feedback force. This feedback force comes from the pushing force of the spring 161, and can also help the user perceive the specific position reached by the operation. Through the cooperation between the ball 162 and the limiting hole 132, this design makes the movement of the handle 11 more precise and can ensure the stability of the handle 11 during movement, avoiding excessive rotation or deviation from the normal operating trajectory.

[0037] In a specific implementation, a circular limiting ring groove 133 is recessed at the bottom of the base plate 13, and the limiting ring groove 133 is arranged on the outer side of the connecting through hole 131. An arc-shaped limiting stopper 17 is installed in the limiting ring groove 133. The transmission shaft cap 141 is arranged at the bottom of the connecting through hole 131. A limiting protrusion 141a is convexly provided on the edge of the transmission shaft cap 141. The limiting protrusion 141a is limitedly arranged in the limiting stopper 17. When in use, when the user rotates the handle 11, the transmission shaft rod 142 drives the transmission shaft cap 141 to move together. When the limiting protrusion 141a contacts the limiting stopper 17, the limiting protrusion 141a is guided by the limiting stopper 17 and prevented from further rotation, thereby limiting the rotation angle of the handle. Through the cooperation between the limiting protrusion 141a and the limiting stopper 17, the system can effectively prevent the handle from excessive rotation, ensure the stability of the system and reduce damage caused by improper operation.

[0038] In specific implementation, a spring washer 18 is provided between the transmission shaft cap 141 and the connection through hole 131, and a flat washer 19 is provided between the screw 15 and the second positioning through hole 112. When in use, the spring washer 18 can effectively absorb vibration and impact during operation, reduce the impact of these external forces on the connection point, and prevent the connection from loosening due to vibration or impact. The flat washer 19 ensures uniform force on each connection point by dispersing the pressure applied by the screw, making the connection more stable.

[0039] In a specific implementation, a mounting groove 114 is recessed at the rear of the handle connecting portion 111, a cover cap 115 is embedded in the mounting groove 114, a positioning block 114a is convexly provided on the inner side wall of the mounting groove 114, a positioning groove 115a is recessed at the edge of the cover cap 115, and the positioning block 114a is embedded in the positioning groove 115a for positioning connection. When in use, the cover cap 115 can cover the internal structure, making the overall design more beautiful and improving the appearance quality of the lock system.

[0040] In a specific implementation, the locking tongue 12 and the bottom plate 13 are both formed by stamping of metal materials.

[0041] In specific implementation, the guide tube 16 is provided with a boss 163 for axial positioning. The inner diameter of the tube is used for guiding the activities of the spring 161 and the ball 162 , and the outer diameter of the tube also plays a role in positioning the handle 11 and the lock tongue 12 .
