[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Referring to Figures 1 to 6, a rear lock body structure of a spherical lock includes a rear lock body 20 connected to the front lock body 10 by a square rod 30. The rear lock body 20 includes a rear lock shell 210, a rear lock cover 220, a battery box 230 arranged in the rear lock shell 210, and a circuit board 270 located inside the rear lock cover 220. A contact end 271 that contacts the battery 200 is provided on the front surface of the circuit board 270, a first terminal 240 connected to the component is provided on the rear lock shell 210, and a second terminal 280 connected to the first terminal 240 is integrated on the circuit board 270. The rear lock cover 220 is detachably connected to the rear lock shell 210.

[0020] The present invention places the battery compartment 230 within the rear lock housing, allowing the battery 200 to be removed and replaced after removing the rear lock cover 220. Furthermore, the circuit board 270 of the present invention utilizes a contact-type connection between the first terminal 240 and the second terminal 280 to output signals and power other components within the lock body. This prevents wired connections on the circuit board 270 from causing solder joints to become detached when the rear lock cover 220 is removed.

[0021] Specifically, the circuit board 270 is fixedly installed inside the rear locking cover 220 by screws.

[0022] Referring to Figures 2 and 3, a pin hole 250 and a snap-in groove 260 are respectively provided on the left and right sides of the inner wall of the rear lock shell 210, and a cylindrical spring pin 222 and a snap member 221 are respectively provided on the left and right sides of the inner wall of the rear lock cover 220. The snap member 221 is movably snapped into the snap-in groove 260, and the cylindrical spring pin 222 is movably inserted into the pin hole 250.

[0023] During assembly, the clamping member 221 is first movably clamped into the clamping groove 260, and then the cylindrical elastic pin 222 is movably inserted into the pin hole 250. During disassembly, the cylindrical elastic 222 is pushed out of the pin hole 250 for quick connection and easy operation.

[0024] 2 , a button 70 corresponding to a button position 272 is provided on the rear lock cover 220. The button 70 triggers the button position 272 on the circuit board 270 to switch between power-off and power-on modes.

[0025] 4 , the contact end 271 is a spring.

[0026] Specifically, the battery box 230 is detachably connected to the rear lock housing 210. To ensure its stability, screws can be used for fixed connection.

[0027] Referring to Figures 1 to 6, a spherical lock structure includes a front lock body 10 and a rear lock body 20 connected to each other by a square rod 30, and also includes a rear lock body structure of the spherical lock. A lock core assembly 40 for driving a clutch assembly 60 is provided inside the front lock body 10. The lock core assembly 40 consists of a lock shell 410 and a lock core 420 rotatably arranged inside the lock shell 410. A dial 50 for driving the clutch assembly 60 is installed on the lower end surface of the lock core 420. A limiting groove 411 is provided on the inner wall of the lock shell 410, and a limiting block 421 embedded in the limiting groove 411 is provided on the outer wall of the lock core 420.

[0028] Specifically, the front lock body 10 is composed of a connecting portion 102 connected to the door body and a rotating portion 101 rotatably disposed on the connecting portion 102 .

[0029] The clutch assembly 60 consists of a clutch fixedly connected to the square rod 30 and a clutch block that plugs into the clutch. The clutch block is mounted on a rotating portion 101 for forward and backward movement, while the clutch is mounted on a connecting portion 102 for rotation. When the clutch block and the clutch are plugged into each other, twisting the rotating portion 101 drives the clutch block, which in turn drives the clutch to rotate, and then drives the square rod 30 to drive the bolt assembly to unlock the lock.

[0030] 6 , the cooperation between the limiting groove 411 and the limiting block 421 can limit the rotation angle of the lock core 420 relative to the lock housing 410, thereby achieving precise rotation of the dial 50. Through structural restrictions, the rotation angle can be effectively controlled to meet the needs of use.

[0031] Specifically, referring to FIG. 2 , a button 70 corresponding to the button position 272 is provided on the rear locking cover 220 .

[0032] 4 , the contact end 271 is a spring.
