Detailed Implementation

[0025] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0026] Example 1: As Figures 1-4 ,include:

[0027] The inner wall of the lock back 100 and the shaft core 100 is fixedly installed with a limiting rubber pad 110, and the limiting rubber pad 110 is provided with a limiting steel ball hole 120 inside.

[0028] The shaft core 130 has an elastic positioning hole on its inner wall. A spring 131 is installed on the inner wall of the elastic positioning hole. A ball bearing 132 is fixedly connected to the end of the spring 131. The ball bearing 132 engages with the inner wall of the limiting ball hole 120 for limiting.

[0029] The specific application scenario of this embodiment is as follows: The lock back 100 serves as the basic component of the door lock. The limiting rubber pad 110 fixed on its inner wall plays a buffering role, and the limiting steel ball hole 120 inside the limiting rubber pad 110 is used for locking. The inner wall of the shaft core 130 is provided with an elastic positioning hole. The spring 131 installed in the hole always applies a pushing force to the ball 132, causing the ball 132 to partially extend out of the elastic positioning hole. When the shaft core 130 rotates, the ball 132 moves with the shaft core 130 and engages with the inner wall of the limiting steel ball hole 120, thereby achieving the limiting and locking of the shaft core 130, preventing it from rotating accidentally in the non-operational state, and ensuring the stability of the basic locking function of the door lock.

[0030] Example 2: Figures 1-6The outer wall of the lock back 100 is fixedly connected to the pin face 160 via the first screw 150. The inner wall of the pin face 160 has an arc-shaped viewing window 161. The inner wall of the pin face 160 is rotatably connected to the shaft pin 164. The shaft pin 164 and the outer wall of the lock back 100 are locked together by a retaining spring 162. The inner wall of the pin face 160 is fixedly installed with a threaded tube 163. The inner wall of the first screw 150 is threadedly connected to the inner wall of the threaded tube 163. The inner wall of the shaft pin 164 is fitted with a drive pin 170. The outer wall of the shaft pin 164 has a screwdriver groove. The outer wall of the drive pin 170 is sleeved with an indicator plate 19. 0. The outer wall of the sign 190 is marked with "occupied" and "unoccupied". The "occupied" and "unoccupied" signs are switched through the arc-shaped viewing window 161. The transmission pin 170 is connected to the pin hole on the inner wall of the rotating block 133 inside the shaft core 130. The outer wall of the shaft core 130 is threaded to the stainless steel cover 140 through the second screw 141. The inner wall of the stainless steel cover 140 is rotatably connected to the handle 180. The handle 180 is fixedly connected to the rotating block 133 by screws. The handle 180 is L-shaped. The end of the handle 180 is fixedly installed with the limiting rubber pad 181.

[0031] The specific application scenario of this embodiment is as follows: The outer wall of the lock back 100 is threadedly connected to the threaded tube 163 on the inner wall of the pin face 160 via the first screw 150, thereby fixing the lock back 100 to the pin face 160; the shaft pin 164 rotatably connected to the inner wall of the pin face 160 is locked to the outer wall of the lock back 100 via a snap ring 162, ensuring stable rotation of the shaft pin 164; the transmission pin 170 inserted into the inner wall of the shaft pin 164 cooperates with the pin hole of the rotating block 133 inside the shaft core 130 to achieve power transmission; the outer wall of the shaft core 130 is connected to the non-lock back 100 via the second screw 141. The stainless steel cover 140 has an L-shaped handle 180 on its inner wall that is fixed to the rotating block 133 by screws. When the handle 180 is turned, the rotating block 133, the transmission pin 170, and the shaft pin 164 rotate synchronously, which in turn causes the indicator 190 on the outer wall of the transmission pin 170 to rotate. The "occupied" and "unoccupied" indicators on the indicator 190 are switched through the arc-shaped viewing window 161 on the pin surface 160. The limiting rubber pad 181 at the end of the handle 180 reduces collision noise during operation, and the screwdriver slot on the outer wall of the shaft pin 164 facilitates installation and adjustment.

[0032] The working principle of this utility model is as follows: When used by those skilled in the art, the lock back 100 is the basic support component of the entire door lock. The limiting rubber pad 110 and the limiting steel ball hole 120 on its inner wall cooperate with the shaft core 130. The spring 131 inside the shaft core 130 pushes the ball 132 out. When the shaft core 130 rotates, the ball 132 engages with the limiting steel ball hole 120, realizing the limiting lock of the shaft core 130 and ensuring the basic locking function of the door lock. The lock back 100 is fixed to the threaded tube 163 of the pin face 160 by the first screw 150. The shaft pin 164 inside the pin face 160 is secured by the retaining spring 162. The locking mechanism is achieved by connecting the transmission pin 170, which is inserted into the shaft pin 164, to the rotating block 133 inside the shaft core 130, forming a power transmission path. Rotating the L-shaped handle 180 inside the stainless steel cover 140, with the end limiting rubber pad 181 providing buffer, can drive the rotating block 133, transmission pin 170, and shaft pin 164 to rotate synchronously, causing the indicator 190 to rotate. Its "occupied" and "unoccupied" indicators are switched through the arc-shaped viewing window 161 to achieve status indication. At the same time, the engagement of the ball bearing 132 with the limiting steel ball hole 120 ensures a stable locking state. The entire system works together to achieve the locking, unlocking, and status indication functions of the door lock.

[0033] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
