Description of the characters Fig. Figure 1 shows a schematic representation of the structure of this utility model; Fig. Figure 2 shows a schematic exploded view of the structure of this utility model. Concrete embodiment

[0013] As in Fig. 1 and Fig.2, a novel frame lock structure comprises a lock housing 100 and a lock body 200, wherein a lock cylinder unit is provided in the lock housing 100 to block the movement of the lock body 200 relative to the lock housing 100, the lock cylinder unit comprises a lock cylinder 310 and a locking element 320 coupled to the lock cylinder 310, wherein the lock body 200 comprises a lock slot 210 that cooperates with the locking element 320, the lock body 200 comprises a locking position and an unlocking position, and when the lock body 200 is in the locking position, the locking element 320 is inserted into the lock slot 210 of the lock body 200 to prevent a change in the position of the lock body 200,wherein the connecting structure of the lock body 200 and the lock cylinder 310 is locked or unlocked by the interaction of the lock slot 210 of the lock body 200 with the locking element 320.

[0014] It further comprises a chain lock head 400, wherein the lock housing 100 comprises a socket for inserting the chain lock head 400, a lock block 500 is provided in the lock housing 100, which prevents the chain lock head 400 from becoming detached from the lock housing 100, a connecting element 600 is provided between the locking element 320 and the lock block 500 and, when the lock cylinder 310 drives the locking element 320 to move, the locking element 320 drives the lock block 500 to move with the aid of the connecting element 600 and thus realizes the switching between the unlocked and locked states of the chain lock head 400, wherein the chain lock head 400 is connected to a chain with which the lock device is locked to an existing fixed structure to prevent the entire bicycle from being carried away.

[0015] The connecting element 600 is rotatably mounted in the lock housing 100 by means of a bolt, wherein the connecting element 600 is provided with a return torsion spring and, if the connecting element 600 is not able to return itself, this consequently impairs the interaction between the locking element 320 and the lock block 500.

[0016] One end of the connecting element 600 is in resilient contact with the locking element 320 and the other end is in resilient contact with the lock block 500 and, since the connecting element 600 is provided with a return torsion spring, it can be ensured that the connecting element 600 always remains in resilient contact with the locking element 320, wherein resilient contact exists between the locking element 320 and the lock housing 100 only in the unlocked state.

[0017] The locking element 320 comprises a locking groove and the lock cylinder 310 accordingly comprises a locking pin, wherein the locking element 320 and the lock cylinder 310 achieve a synchronous movement through the locking connection between the locking groove and the locking pin, and the fixed assembly structure of the locking element 320 and the lock cylinder 310 is achieved by means of an assembly by a locking connection between a locking groove of a certain shape and a correspondingly shaped locking pin, wherein the assembly structure is simple and the installation is stable.

[0018] The chain lock head 400 includes an annular groove 410, and the upper end of the lock block 500, which fits into the annular groove 410, is semi-cylindrical, the lock block 500 being driven to rotate relative to the lock housing 100 by the connecting member 600, and a return torsion spring is provided between the lock block 500 and the lock housing 100, so that when the half-cylinder of the lock block 500 is rotated into the annular groove 410, the chain lock head 400 is in the locked state, the lock block 500 always remaining locked to the chain lock head 400 without applying an external force, and when the connecting member 600 electrically [sic!; Translator's note: This is probably a typo in Chinese, so "electrically" should be deleted.] is set in rotation, the half cylinder of the lock block 500 rotates out of the annular groove 410 of the chain lock head 400, so that the chain lock head 400 can then be pulled out of the lock housing 100, wherein the lock block 500 always remains in the state of spring force storage at this time due to the spring force of its own return torsion spring and, when the connecting element 600 has returned, the lock block 500 also elastically returns due to its own return torsion spring.

[0019] The lock body 200 is provided with a handle 700 which serves to move the lock body 200 relative to the lock housing 100 by an external force, so that the lock body 200 can be set in motion.

[0020] The lock housing 100 comprises an upper housing part 110 and a lower housing part 120, wherein an anti-burglary protection plate 130 is welded to the inner wall of the lower housing part 120, which anti-burglary protection plate protrudes beyond the side wall of the lower housing part 120. By welding the anti-burglary protection plate 130 to the inner wall of the lower housing part 120, it can serve as a lateral anti-burglary protection and thus increase the security and anti-theft effect of the lock device.

[0021] A threaded part 140 is welded into the lower housing part 120, which serves to screw in a bolt, and the upper housing part 110 and the lower housing part 120 are firmly connected to each other by the screw connection between the bolt 150 and the threaded part 140. For the fixed structure of the upper housing part 110 and the lower housing part 120, a fixed screw connection is used, which has good stability. In addition, screws with a broken head are used, which means that after assembly using a tool, the screw head is broken off so that unscrewing using a tool cannot be carried out, which provides relatively good theft protection because disassembly is prevented.

[0022] The present utility model provides a novel frame lock structure, wherein the frame lock is additionally provided with a chain lock head, and the locking and unlocking state of the chain lock head is controlled by the movement of the lock cylinder, which not only provides convenient operation but also effectively ensures the locking of the bicycle itself for anti-theft protection, and whereby the bicycle can also be locked to an existing structure for anti-theft protection, thus achieving a high degree of security, while the operation is convenient and the structure of the inner lock cylinder is simple.
