具体实施方式
实施例：一种防敲击开启底开密码挂锁，包括锁体外壳、锁环9、密码轮组和锁闸6，所述锁体外壳一端形成有两个与内腔连通的锁环9孔，呈U形的锁环9两端分别能够经锁环9孔插入锁体外壳内腔中，锁环9至少一端侧壁上设有卡槽结构22，锁闸6能够沿垂直锁环9延伸方向滑动的安装于锁体外壳的内腔中，锁闸6能够插设于锁环9的卡槽结构22内阻止锁环9脱出锁体外壳的锁环9孔，若干密码轮组分别能够转动的安装于锁体外壳的内腔中，锁体外壳上设有供密码轮组上密码标识露出的开窗，还设有控制板4和控制板复位弹性件5，锁体外壳内腔两相对的侧壁上分别设有一轴孔或转轴19，控制板4两相对的侧壁上分别设有转轴19或轴孔，所述转轴19能够转动的插设于轴孔内，所述控制板4位于转轴19两侧分别形成有插接止挡臂20和接触控制臂21，所述插接止挡臂20能够随控制板4转动到达闭 锁位置或开锁位置，位于闭锁位置的插接止挡臂20与锁闸6接触并阻挡锁闸6脱离锁环9上的卡槽结构22，位于开锁位置的插接止挡臂20与锁闸6分离，所述控制板4的接触控制臂21紧抵密码轮组的各个内轮2偏心外圆周面上，所述控制板复位弹性件5给控制板4提供保持接触控制臂21与密码轮组的内轮2始终紧密接触的弹性保持力。
当各个密码轮组转动到与正确密码正对的状态时，所有内轮2偏心外圆周面上高度最低的部位与控制板4的接触控制臂21正对，控制板4在控制板复位弹性件5的顶出作用下，绕着两侧的转轴19正向旋转，控制板4的插接止挡臂20就会脱离锁闸66，如图7所示。向外拉锁环99时，锁环9上的卡槽可以迫使锁闸6退出，锁环9失去锁闸6的阻挡就可以被顺利拉出，进而实现开锁，锁闸6一般与锁环9上的卡槽通过斜面接触，可以实现顺利退出。
当各个外密码轮组没有转动到与正确密码正对的状态时，就会有一个或多个内轮2偏心外圆周面上高度高的部位与控制板4的接触控制臂21正对，此时，处于锁闭状态的控制板4无法转动，控制板4上的插接止挡臂20与锁闸6保持紧密接触的阻挡状态，锁闸6无法退出锁环9上卡槽结构22，无法开锁，对于处于开锁状态的控制板4来说，当密码组转到错误密码状态时，控制板4的接触控制臂21被一个或多个内轮2偏心外圆周面上高度高的部位顶起，控制板4就会绕其两侧的转轴1919反向旋转，控制板4的插接止挡臂20就会下沉到锁闭状态，紧抵着锁闸6，使锁闸6无法退出锁环9上的卡槽结构22，如图3、图8所示，此时整锁处于锁闭状态。
本发明的控制板4在开锁和闭锁过程中始终绕其两侧的转轴19转动，受到转轴19的约束，无法发生其他方向的运动，且由于其在闭锁状体转动方向受到内轮2偏心外圆周面的阻挡，无论锁体受到如何大的震动，控制板4在锁闭状态都无法发生反向转动到开锁位置，因此，锁体即使受到敲击产生震动，控制板4的插接止挡臂20也无法脱离锁闸6，具有良好的防敲击开锁性能，大大提高了底开密码挂锁的使用安全性。
所述控制板4上的接触控制臂21为梳子状结构，密码轮组的各个外轮1位于接触控制臂21梳子状结构的梳齿间隙中，接触控制臂21的各个梳齿分别紧密接触各个密码轮组的内轮2偏心圆周外侧面。通过类似梳子结构的接触控制臂21，实现了对密码轮组外轮1的避让，同时可以保证与每一个内轮2的偏心圆周外侧面保持紧密接触，接触控制臂21除了采用梳子状结构避让外轮1，也可以通过形成避让凹陷结构来避让外轮1，此类都是本领域技术人员根据本专利很容易想到的等同替换结构，属于本专利保护范围。
所述锁环9两端相对的侧壁上分别设有卡槽结构22，两个锁闸6分别能够沿锁环9宽度方向相对滑动的安装于锁体外壳内部，控制板4的插接止挡臂20随控制板4转动能够插入或退出两个锁闸6之间的间隙内。通过两个锁闸6分别卡住锁环9两端侧壁，提高了锁环9锁闭稳定性，当然也可以只卡住锁环9一端侧壁，只要能阻止锁环9拉出即可。
还设有滑杆8和锁闸弹簧7，两个锁闸6分别能够滑动的套设于滑杆8外侧，锁闸弹簧7套设于滑杆8外侧，且锁闸弹簧7弹性伸缩的两端分别紧抵两个锁闸6相对的侧壁上。滑杆8对两 个锁闸6相对滑动起到导向作用，锁闸弹簧7可以给锁闸6提供保持相互远离的位置状态，使控制板4的插接止挡臂20在锁闭时顺利进入两个锁闸6之间对二者进行滑动阻挡。
所述控制板4的插接止挡臂20侧壁上设有凸起部23，锁闸6侧壁上设有凹陷部24，所述控制板4的插接止挡臂20上的凸起部23能够插设于锁闸6侧壁上的凹陷部24内，所述控制板4的凸起部23边缘形成有倒角结构，锁闸6侧壁上的凹陷部24朝向控制板4的插接臂脱出一侧为使凹陷部24开口增大的斜面。锁闭状态时，控制板4的插接止挡臂20侧壁上的凸起部23可以插在锁闸6侧壁上的凹陷部24内，进一步避免控制板4受到震动发生翻转。
所述锁体外壳包括外套18、下盖11、上盖10和底盖14，所述上盖10与下盖11开口固定拼接在一起，上盖10与下盖11共同形成一端开口的桶形结构，上盖10和下盖11中至少一个上形成有若干间隔设置的密码轮定位槽，密码轮组能够转动的容纳于各个密码轮定位槽内，下盖11和上盖10内部还共同形成有供控制板4两侧壁上转轴19安装的两个轴孔和供锁闸6容纳的滑道，底盖14固定覆盖于上盖10和下盖11形成的桶形结构开口外侧，底盖14上形成有供各个密码轮组的外轮1露出的开窗，密码轮组上的密码标识位于外轮1圆周外侧表面上，所述外套18固定套设于上盖10、下盖11和底盖14共同形成的内壳外侧。通过上盖10、下盖11和底盖14形成了一个内壳，用于对密码轮组、控制板4、锁闸6和锁环9的组装定位，上盖10与下盖11可以为开口方向正对的盖体结构，组装时，先将密码轮组、控制板4、锁闸6和锁环9在下盖11内进行初步组装定位，然 后将上盖10盖在下盖11上，二者通过连接螺丝等连接件进行固定即可，然后将底盖14盖在上盖10和下盖11形成的桶状结构开口处，形成供密码轮组露出的底部外壳，最终将外套18固定套在上盖10、下盖11和底盖14共同形成的锁芯结构外侧即可，该种方式便于锁体的组装，且外套18可以做的更加美观。
所述锁体外壳上设有连接孔25，上盖10、下盖11和底盖14共同形成的内壳侧壁上形成有插销孔26，所述插销孔26与锁体外壳侧壁上的连接孔25正对，所述连接孔25和插销孔26内固定插设有一定位销15。通过定位销15将外套18和内壳进行固定定位，结构简单，最佳在定位销15外侧形成齿形结构，当其紧密插入连接孔25和插销孔26内后，可以与连接孔25或/和插销孔26内侧壁形成嵌合连接，避免定位销15脱落，且该种定位结构，能够防止外界将外套18拆卸下来对锁体进行拆解开锁，此外，外套18与内壳还可以通过焊接、粘接等方式进行定位，此类都是本领域技术人员根据本专利很容易想到的等同替换结构，属于本专利保护范围。
所述下盖11内侧壁上还设有弹簧插孔27，控制板复位弹性件5一端插设于所述弹簧插孔27内，控制板复位弹性件5另一端紧抵控制板4表面，所述控制板复位弹性件5与控制板4接触位置位于转轴19更靠近插接止挡臂20一侧。
控制板复位弹性件5采用压簧结构，通过受压缩产生弹性蓄能，其一端插在下盖11的弹簧插孔27内，起到了定位和导向作用，避免其受压产生横向变形损坏，也可防止其受震动后脱离原位，确保其保持稳定的弹力释放状态。
所述锁环9为一端长度长于另一端长度的非对称结构，其长 度长的一端侧壁上形成有一圈环形内凹环28和一偏心避让槽29，所述上盖10和下盖11之间还共同形成有供锁环9长度长的一端容纳的锁环9滑槽，锁环9滑槽内固定设有一限位凸起17(限位凸起17可以一体成型于锁环9滑槽内，也可以为插在锁环9滑槽侧壁上的销子)，所述限位凸起17恰伸入锁环9的环形内凹环28内，所述密码轮组包括外轮1、内轮2、中心轴3和密码轮弹性件13，所述内轮2圆周方向止动且轴向能够滑动的插设于外轮1内侧，内轮2上偏心外圆周面露出于外轮1外侧并止档于外轮1轴向一端端面上，内轮2能够转动的套设于中心轴3外侧，相邻内轮2轴向端面紧密接触，中心轴3两端分别形成有径向外扩台阶结构12，所述径向外扩台阶结构12止挡于位于中心轴3两端的内轮2端面上，中心轴3一端能够伸入到锁环9滑槽内并与锁环9上的偏心避让槽29正对，密码轮弹性件13给中心轴3另一端提供朝向一端方向的弹性保持力。该结构使得挂锁上的锁环9始终与锁体连接，避免了锁环9与锁体分离丢失，锁环9通过拉出一定的距离实现开锁即可，锁环9在密码正确时转动可以顶着中心轴3向另一端方向移动，进而将密码轮组的内轮2顶出到外轮1外侧，使内轮2与外轮1分离，进而可以实现密码修改，密码修改完成后，在密码轮弹性件13作用下可以实现内轮2复位到与外轮1插接状态。
锁体外壳内腔中还固定安装有密码轮弹片16，密码轮弹片16一端形成有与密码轮组一一对应的弹性接触部，所述密码轮组的外轮1圆周外侧表面上设有与密码标识对应的接触槽，密码轮弹片16一端的弹性接触部能够弹性紧抵密码轮组的外轮1表面，且密码轮弹片16一端的弹性接触部能够容纳于密码轮组圆 周外侧壁上的接触槽内。密码轮弹片16始终弹性接触密码轮的外轮1，外轮1每转到一个密码标识与锁体外壳开窗正对位置，密码轮弹片16的弹性接触部就自动进入密码轮轮的接触槽内，实现密码轮组的自动定位，防止密码轮受到拨动力作用乱转。
