An unlocking button in the indoor handle is slid so that a cylinder on the unlocking button is stuck in the spiral groove, thereby driving a safety rod in a square hole A of the knob to rotate. The rotation of the safety rod drives a locking cam in a blocking cover on the outdoor handle to rotate, thereby realizing a locking or unlocking function.

[0007] The unlock button is set on the side of the indoor handle. Pushing and sliding the unlock button can realize the locking / unlocking operation.

[0008] Preferably, a cam and a display block with a torsion spring inserted into the tail of the cam are provided in the outdoor handle; the end of the safety rod away from the square hole A is installed in the square hole B of the cam; the rotation of the safety rod drives the cam to rotate, so that the black surface or the red surface on the display block is aligned with the display hole on the outdoor handle.

[0009] Preferably, the torsion spring on the display block drives the torsion arm of the display block to contact the inclined surface of the cam.

[0010] Preferably, when the black surface on the display block faces the display hole on the outdoor handle, it is in the unlocked state.

[0011] Preferably, the red surface on the display block is in a locked state when it faces the display hole on the outdoor handle.

[0012] The small hole set on the outdoor part of the handle is a display hole. The black side or the black side can be observed through the display hole, which respectively indicates the unlocking / locking status and indicates whether there is someone in the room.

[0013] Preferably, an emergency unlocking mechanism is provided in the outdoor part handle, which consists of a handle sleeve and a reset spring. By pressing the display block downward, the spiral slope on the cam contacts the convex point on the handle sleeve, causing the cam to rotate and drive the safety lever to rotate for emergency unlocking.

[0014] Preferably, when the pressed display block is released, the cam is reset under the action of a reset spring.

[0015] Press the status display hole outdoors with a cylindrical object to push the display block down, so that the door can be unlocked from outdoors in an emergency.

[0016] Compared with the prior art, the technical effects and advantages of the utility model are:

[0017] In this bathroom lock structure, when the unlock button on the indoor handle is pushed, the cylinder on the unlock button is stuck in the spiral groove of the knob, driving the knob to rotate. The knob drives the safety rod to rotate through the square hole A, and then drives the locking cam in the baffle cover on the outdoor handle to rotate, realizing the locking or unlocking function.

[0018] In this bathroom lock structure, when the safety rod rotates, the locking cam is driven to rotate to realize the locking function. At the same time, the safety rod and the cam are connected through the square hole B to drive the cam to rotate. The inclined surface on the cam contacts the torsion arm on the display block to drive the display block to rotate. When the cam rotates to a specific angle, the black surface or red surface on the display block is aligned with the display hole on the outdoor handle, indicating that the current state is locked or unlocked.

[0019] When emergency unlocking is required, a round rod is used to push down the display block through the display hole, so that the spiral slope on the cam contacts the convex point on the handle sleeve. In this way, the cam rotates, driving the safety rod to rotate, realizing the emergency unlocking function. After releasing the pressed round rod, the entire cam structure returns to its original position and is reset by the reset spring.

[0020] This bathroom lock structure achieves reliable locking and unlocking functions through sophisticated mechanical design, and also has emergency unlocking function, which improves the flexibility and convenience of use. The state of the lock can be observed through the display hole on the outdoor handle, so that the user can clearly understand the current state of the lock, which increases safety. The whole structure is reasonably designed and easy to operate, which improves the user experience. BRIEF DESCRIPTION OF THE DRAWINGS
