具体实施方式
结合以下实施例对本发明作进一步描述。
本发明的箱包密码锁的具体实施方式，如图1-图2所示，包括底壳1，底壳1安装有密码锁组件3和钥匙锁组件4，底壳1还安装有锁扣机构2，密码锁组件3与钥匙锁组件4联动联接。如图1和图2所示，钥匙锁组件4包括旋钮41、锁芯42、拨块43和转块44，锁芯42穿设在旋钮41中，拨块43设于锁芯42下方，转块44安装于拨块43和旋钮41下方。密码锁组件3上锁且钥匙锁组件4上锁时，旋钮41无法旋转；密码锁组件3开锁时，旋钮41可旋转实现解锁；密码锁组件3上锁时，通过钥匙***锁芯42带动锁芯42和拨块43转动后，旋钮41可旋转实现解锁。本箱包密码锁包含以下两种解锁方式：一是利用密码锁组件3输入正确的密码，密码锁组件3开锁后，通过旋转旋钮41实现解锁；二是利用钥匙***锁芯42，通过钥匙带动锁芯42和拨块43转动，然后通过旋转旋钮41实现解锁。
如图1和图2所示，底壳1还安装有第一连接杆51和第二连接杆52，第一连接杆51 和第二连接杆52分别位于转块44的两侧，且均与转块44联动联接。第一连接杆51和第二连接杆52均设有联动槽53，转块44设有两个联动柱441，两个联动柱441分别位于第一连接杆51上和第二连接杆52上的联动槽53。在进行解锁时，转块44转动带动第一连接杆51和第二连接杆52相离运动，进而实现解锁。优选的，联动槽53为长腰形槽，且该长腰形槽的长度垂直于第一连接杆51/第二连接杆52的移动方向，长腰形槽的设置，使得第一连接杆51和第二连接杆52的移动能够更好地趋近于直线运动，使得控制更稳定以及能够适当地减少锁具本体整体的体积。第一连接杆51和第二连接杆52之间设有连接杆弹簧54，第一连接杆51和第二连接杆52相离运动时，连接杆弹簧54产生形变，连接杆弹簧54用于使第一连接杆51和第二连接杆52相向运动实现复位。第一连接杆51和/或第二连接杆52设有限制孔55，底壳1设有经过限制孔55的限位件56，限位件56与限制孔55配合以限制第一连接杆51和第二连接杆52的移动距离，避免在解锁时旋钮41或锁芯42旋转的角度过大影响本箱包密码锁的正常使用。
如图1和图2所示，锁扣机构2包括结构相同的第一锁扣机构和第二锁扣机构，第一锁扣机构和第二锁扣机构分别位于底壳1两端。第一锁扣机构与第一连接杆51联动联接；第二锁扣机构与第二连接杆52联动联接。
如图3和图4所示，每一锁扣机构2内均包括底座20、锁盖21、锁钩22、转动块23和推块24，底座20与上箱壳固定连接，底座20由四个侧板围成，其顶部向上凸伸有凸块200，该凸块200的内壁设有扣槽201，底座20的左侧板202、右侧板203均设有一限位孔204，底座20的底壁为一盖板205，盖板205包括主体206和支杆207，支杆207的数量为两个，两个支杆207分别位于主体206右侧的两端，每一支杆207的上端均设有一缺槽2070，盖板205的左侧和后侧上均设有一能限制推块24过度移动的限位块209，该限位块209连接在盖板205的上表面，限位块209朝向左和向右均延伸有锁块2090，两个锁块2090能够分别***到与其对应的限位孔204内，通过限位孔204与锁块2090的卡接，能够将盖板205与底座20固定连接在一起，防止盖板205从底座20上脱落。盖板205还设有缺口208，缺口208能够贯穿其上下表面。
转动块23位于底座20内，且转动块23位于两个支杆207之间，且转动块23的中部设有铰接孔230，缺槽2070的位于对应铰接孔230的位置，一铰接杆231***到铰接孔230内并穿过缺槽2070后***到底座20的前侧板和后侧板上。转动块23的顶部向下凹陷形成有卡槽232，转动块23的左侧板202上连接有凸起233，该凸起233与转动块23的底部形成有凹槽234。转动块23的上端与底座20的左侧板202之间设有弹性件235，当转动块23的下端朝向右侧转动时，转动块23能够以铰接杆231为铰接点，进而使得转动块23的上 端朝向左侧转动，当解除对转动块23下端的力时，弹性件235能够抵推转动块23的上端复位。
锁扣机构2还包括离合块25，离合块25能够限制转动块23的转动，离合块25位于转动块23的下方，离合块25包括挡止部250、按压部251和铰轴252，挡止部250和铰轴252均位于按压部251的前侧和后侧，铰轴252的两端能够与底座20铰接，按压部251自挡止部250的前侧朝下延伸，按压部251的位置与缺口208的位置相对应，按压部251与推块24接触的一面为倾斜面，当推块24移动并推动该按压部251时，能够将按压部251压入到缺口208内。挡止部250用于与凸起233配合，挡止部250的底部与盖板205之间连接有弹性件235，当推块24推动按压部251向下朝向缺口208移动时，离合块25铰轴252作为铰接点，使得弹性件235产生形变，弹性件235压缩，从而使得挡止部250与凸起233脱离，解除对转动块23的转动限制。设置该离合块25限制转动块23的转动，能够防止当箱包密码锁发生振动时，导致转动块23转动，使得箱包密码锁意外解锁，本实施例中的离合块25，起到保险作用，只有当推块24推动离合块25解除了对转动块23的限制，转动块23才能转动，从而实现解锁。
推块24的一端扣合第一连接杆51/第二连接杆52，推块24的另一端***到底座20内，且能够在盖板205上移动，推块24的内壁设有上下连接的第一推动部240和第二推动部241，第一推动部240与转动块23的凸块200接触的面为上接触面242，上接触面242为倾斜面，第二推动部241与离合块25的按压部251接触的面为下接触面243，下接触面243为倾斜面，且下接触面243位于上接触面242的前侧，当推块24移动时，推块24的下接触面243先抵压按压部251向下移动，以使得按压部251解除对转动块23的限制后，上接触面242在推动转动块23的下端朝向一侧转动，从而使得转动块23以其铰接孔230为铰接点转动，以使得转动块23的上端朝向另一侧转动。推块24的底部设有限位槽244，限位块209位于限位槽244内，当推块24移动时，限位槽244向前向后移动均能被限位快挡止住，能够防止推块24在盖板205上过度移动，导致推块24的结构损坏。
下箱壳上设有锁扣6，锁盖21的一端与底座20铰接，另一端能够锁紧在下箱壳上，锁盖21的顶壁向下延伸有通孔210，该通孔210的位置与锁扣6的位置相对应，转动块23与锁钩22联动连接，转动块23转动能够带动锁钩22移动，锁钩22的两端部分别为***端和联动端，联动端向下延伸有卡块220，该卡块220***卡槽232内与卡槽232卡接，***端***通孔210内，并能够通过通孔210进入到锁扣6内，从而能够将锁盖21锁紧在下箱壳上。锁钩22的联动端的底部还连接有延伸块221，该延伸块221朝向扣槽201的方向延伸，当转动块23转动使得锁钩22和锁扣6解锁时，延伸块221能够抵顶扣槽201上方 的侧壁，使得转动块23的凸块200底部抵顶离合块25，防止离合块25复位并卡住转动块23而导致转动块23不能实现复位，进而使得锁钩22不能实现上锁。当延伸块221抵顶扣槽201上方的侧壁时，此时需要上锁，则按压锁盖21的顶部，使得锁盖21向下移动，同时延伸块221同步向下移动并***到扣槽201内，锁钩22和锁扣6锁紧，实现上锁。
如图1所示，本箱包密码锁还包括把手座7，把手座7安装在底壳1上端对应密码锁组件3和钥匙锁组件4的位置，旋钮41贯穿把手座7。把手座7转动连接有把手70，把手70与把手座7之间设有扭簧71，把手70转动至垂直于把手座7所在的箱壳时，扭簧71产生形变。
如图1和图2所示，在进行开锁时，通过密码锁组件3开锁或采用钥匙***锁芯42开锁，然后通过转动旋钮41带动转块44转动，转块44转动使得第一连接杆51和第二连接杆52相离运动，第一连接杆推动第一锁扣机构2的推块24移动，第二连接杆推动第二锁扣机构2的推块24移动，使得推块24推动离合块25解除对转动块23的限制(如图3所示)，使得转动块23的下端能够被推动，当转动块23的下端转动时，以使得转动块23的上端转动并带动锁钩22脱离上箱壳，从而实现解锁。本箱包密码锁通过转块44、第一连接杆51、第二连接杆52以及两组锁扣机构2的配合设置，使得能够通过一个旋钮41或锁芯42实现对两组锁扣机构2的同步控制解锁，使得操作更简单方便，控制相对更灵活且安全性和可靠性更强，同时有效地减少了整体零件的数量，使得结构相对更简单和紧凑。
最后应当说明的是，以上实施例仅用以说明本发明的技术方案，而非对本发明保护范围的限制，尽管参照较佳实施例对本发明作了详细地说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的实质和范围。
