DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figure 1-Figure 5 The utility model provides a technical solution: a new type of lock body, including a lock core body 1, a lock body bottom shell 2, a lock body base 3, a lock body key 4, a docking inner groove 5, a docking long block 6, a lock core internal component 7, an installation groove 8, a limit clamping component 9 and a lock body outer shell 10. The top of the lock core body 1 is connected to the lock body key 4, and the bottom of the lock core body 1 is also connected to the lock core internal component 7. A plurality of installation grooves 8 are arranged on the surface of the lock body bottom shell 2, and the bottom surface of the lock body bottom shell 2 is also equipped with a lock body base 3. A docking inner groove 5 is opened at the end of the lock body key 4, and the docking inner groove 5 is consistent with the size of the docking long block 6. The lock body outer shell 10 is connected to the lock core internal component 7 through a plurality of limit clamping components on the lock core internal component 7. Component 9 is installed between the lock core body 1 and the lock body bottom shell 2. The internal component 7 of the lock core includes a lock core inner ring 71, an inner ring 72 and a pull strip 73. A plurality of inner rings 72 are arranged inside the lock core inner ring 71, and a pull strip 73 is fixed on the surface of each inner ring 72. The pull strip 73 is connected to the limit clamping component 9. The limit clamping component 9 includes a telescopic pin 91, a bottom panel 92, an external pin 93, a fixing rod 94 and a tension spring 95. A tension spring 95 is arranged inside the telescopic pin 91, and the tension spring 95 is connected to the pull strip 73. A bottom panel 92 is also assembled at the bottom of the telescopic pin 91, and the bottom panel 92 is connected to the inner wall of the external pin 93 through the fixing rod 94 at the bottom.

[0021] As the first embodiment of the utility model: multiple mounting grooves 8 are used to fix the lock body bottom shell 2 and the lock body outer shell 10 with positioning bolts. The design connects the lock body outer shell 10 and the lock body bottom shell 2 by opening multiple mounting grooves 8, which is conducive to convenient disassembly. The internal collar 72 is consistent with the overall size of the docking long block 6, and the length of the docking long block 6 also meets the needs of the internal components 7 of the lock core. The design controls the switch of the lock body by inserting the internal collar 72 through the docking long block 6. The structure is reasonable, which helps to improve the overall switch effect of the lock body. The bottom of the pin 93 is fixed to the surface of the lock core inner ring 71 by welding, and the external pin 93 is matched with the telescopic pin 91, the top of the tension spring 95 is tied together with the pull rod 73, and the bottom of the tension spring 95 is welded to the bottom panel 92. This design uses the pull rod 73 to apply tension to the tension spring 95, thereby achieving the effect of extending and retracting the telescopic pin 91. The internal size of the lock body jacket 10 matches the size of the lock core inner ring 71. This design uses the lock body jacket 10 to cover the lock core inner ring 71, which helps to further enhance the anti-theft effect of the lock body.

[0022] As a second embodiment of the present invention: when the user is unlocking the lock, he first aligns the lock body key 4 with the lock core body 1, so that the docking inner groove 5 in the lock body key 4 corresponds to the docking long block 6, and then twists the lock body key 4, the docking long block 6 will rotate with it, because the docking long block 6 is covered with a plurality of inner rings 72, these inner rings 72 will rotate with the docking long block 6, so that the pull strip 73 on the inner ring 72 will pull the tension spring 95 in the limit clamping assembly 9, and the bottom of the tension spring 95 is resisted by the bottom panel 92, and then with the compression of the tension spring 95, the telescopic pin 91 will be retracted into the outer pin 93, so that the limit of the limit clamping assembly 9 will be lost on the inner ring 71 of the lock core, and the lock core body 1 will be opened. Similarly, when locking the lock body, the user twists the lock body key 4 in the opposite direction, the inner long block 6 will release the pull strip 73, and then the tension spring 95 will be reset, so that the telescopic pin 91 also extends back, achieving the effect of limiting the lock body jacket 10.
