Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, the sinking type fixing lock, which is one type of a case zipper combination lock, includes a housing including a lock case 11 and a bottom cover 12. The lock shell 11 is provided with a cipher wheel unlocking assembly, a key unlocking assembly, a lock tongue group, a connecting rod 5 and a connecting block, wherein the lock tongue group is positioned between the key unlocking assembly and the cipher wheel unlocking assembly. The password wheel unlocking assembly comprises a central rod 21 and three password wheel groups 22 sleeved on the central rod 21, one end of the central rod 21 is provided with a spread panel 211, and the other end of the central rod 21 is provided with a number changing assembly 23. The key unlocking component comprises a push button 31, a lock core and a lock core baffle, wherein the upper end of the push button 31 is exposed out of the end face of the lock shell 11. The lock tongue group is connected with the key unlocking component in a linkage way, and is used for realizing the buckling or the separation of the zipper head of the case. One end of the connecting rod 5 is in linkage connection with a push button 31 of the key unlocking assembly, the other end of the connecting rod 5 is in linkage connection with one end of a connecting block, the other end of the connecting block is in linkage connection with the central rod 21, and the connecting block is rotatably connected to the lock shell 11.
The sinking type fixed lock in the embodiment comprises the following two unlocking modes: 1. when the three password wheel sets 22 are all corresponding correct unlocking numbers, the password wheel unlocking assembly is unlocked, the central rod 21 can move, the key unlocking assembly can be driven to integrally move by pushing the push button 31, the lock tongue group is driven to move when the key unlocking assembly integrally moves so that the zipper head of the case is separated, unlocking is further realized, the connecting rod 5 is driven to move when the key unlocking assembly integrally moves, the connecting rod 5 drives the connecting block to rotate, and the connecting block rotates to drive the central rod 21 to move; 2. when the unlocking key is inserted into the lock core to rotate the lock core, the lock core baffle drives the lock tongue group to move so that the zipper head of the case is separated, and further unlocking is realized. When the cipher wheel unlocking assembly is locked, the central rod 21 is limited to be unable to move, and the key unlocking assembly cannot be driven to move integrally through the push button 31 to unlock.
The connecting block comprises a positioning part 61, a tension part 62 and a pushing part 63, the connecting block is rotationally connected to the lock shell 11 through the positioning part 61, the connecting block is in linkage connection with the other end of the connecting rod 5 through the tension part 62, the pushing part 63 abuts against the expansion plate 211 at the end part of the center rod 21, and linkage connection between the connecting block and the center rod 21 is further realized. The other end of the connecting rod 5 is provided with a baffle block 51, and the baffle block 51 is abutted against the tension part 62. When the key unlocking assembly integrally moves, the connecting rod 5 is driven to move, the connecting rod 5 pulls the tension part 62 of the connecting block through the baffle block 51, so that the connecting block rotates, and when the connecting block rotates, the central rod 21 is pushed to move through the expansion plate 211.

The two hook members 42 are provided with two grooves 421, and the linkage part 433 of the stop block 43 drives the hook members 42 to rotate through the grooves 421, so that the linkage between the stop block 43 and the hook members 42 is more stable. The force bearing surface of the groove 421 abutting against the corresponding linkage part 433 of the stop block 43 is an inclined surface, and the contact area can be effectively increased when the force bearing surface of the corresponding linkage part 433 of the parallel stop block 43 abuts against the groove 421, so that the stop block 43 and the hook piece 42 can be linked better. Both hook members 42 are pivotally connected to the frame 41 by means of pins 45. And a second torsion spring 46 is arranged between the two hook pieces 42 and the frame 41, and when the stop block 43 drives the hook pieces 42 to rotate to release the restriction of the zipper heads of the bags, the second torsion spring 46 deforms, and the elastic force generated by the deformation of the second torsion spring 46 can drive the hook pieces 42 to rotate and reset. The two hook pieces 42 are provided with insertion inclined planes 422, and the zipper heads of the bags are convenient to drive the hook pieces 42 to rotate through the insertion inclined planes 422, so that the limitation of the zipper heads of the bags is realized.
The linkage of key unlocking component and cipher wheel unlocking component is realized by adopting the connecting block which is rotationally connected with the lock shell 11 in the embodiment, compared with the prior art, the connecting block and the central rod 21 of the cipher wheel unlocking component in the embodiment are not easy to misplace, so that the linkage is better, and the stability of the whole structure is better. In addition, the spring bolt group in this embodiment is the integration installation, compares two sets of spring bolt subassemblies one by one in prior art and installs, and simple installation can guarantee whole assembly accuracy simultaneously better.
The present embodiment is only for explanation of the present invention and is not to be construed as limiting the present invention, and modifications to the present embodiment, which may not creatively contribute to the present invention as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present invention.
