Description

方便开锁的U型长梁锁 技术领域
本发明涉及一种长梁锁，特别是方便开锁的U型长梁锁。
背景技术
目前，市场上常见的U型长梁锁都是将锁体套在锁梁上进行锁定的，而此类U型长梁锁的锁芯是与锁梁长度方向平行，需要开锁时，手部容易被伸出锁体的锁梁挡住，导致开锁不方便的问题；而现有的锁芯位于锁体侧面的挂锁，例如CN201811265817.6记载的挂锁结构，此类挂锁结构开锁时，通过凸轮状的锁芯转动将芯柱推动，芯柱压缩弹簧，使得锁栓能回缩入芯柱上的凹槽内进行开锁，此类挂锁使用时，拉动锁梁的同时震动锁体能使芯柱压缩弹簧，从而将锁梁拉开，防盗性能较差。因此，现有的长梁锁存在着开锁不方便和防盗性能较差的问题。
发明内容
本发明的目的在于，提供一种方便开锁的U型长梁锁。本发明不仅能够方便开锁，还具有防盗性能较好的优点。
本发明的技术方案：方便开锁的U型长梁锁，包括U型的锁梁和锁体，锁梁上设有多个卡齿；所述锁体上设有与锁梁配合的通孔，锁体内设置有两个分别朝向两侧通孔的定位件；每个定位件的一端部均与卡齿配合设置，两个定位件之间的位置处设置有与通孔平行的转动块；转动块的一侧设置有与锁梁长度方向垂直的锁芯，转动块上朝向锁芯一端固定有圆周分布的传动齿，锁芯的侧面固定有与传动齿啮合的齿片；所述转动块转动至不同角度能改变定位件对锁梁的锁定状 态。
前述的方便开锁的U型长梁锁中，所述转动块的侧面设有让位槽，让位槽与定位件配合设置。
前述的方便开锁的U型长梁锁中，所述转动块上远离锁芯的一侧设置有与锁体侧壁配合卡接的封块，封块和转动块上均设有导向孔，导向孔内设置有转轴。
前述的方便开锁的U型长梁锁中，所述转动块转动能将定位件朝远离通孔的方向拉动。
前述的方便开锁的U型长梁锁中，所述锁体上对应定位件伸缩方向的位置处设有安装槽，锁体侧壁上对应安装槽的位置处设置有槽盖。
前述的方便开锁的U型长梁锁中，所述定位件包括外套筒，外套筒内设置有异形舌头，异形舌头与外套筒之间设置有弹簧。
前述的方便开锁的U型长梁锁中，所述定位件为舌条，舌条的一端设有舌头，舌条的另一端部固定有卡块；舌头的顶面为倾斜面，舌头的底面为水平面；所述转动块上对应卡块一侧的位置处固定有推块。
前述的方便开锁的U型长梁锁中，所述锁体内设置有两个前后配合并左右对称设置的舌条，两个舌条端部的舌头分别朝向两侧的通孔，两个舌头之间位置处设置有复位弹簧；左侧舌条上的卡块位于右侧舌条上卡块的右侧；所述转动块上的两个推块位于两个卡块的之间。
前述的方便开锁的U型长梁锁中，所述锁体上对应锁芯的外侧滑动设置有锁芯套，锁芯套与锁芯之间滑动设置；锁体上对应锁芯套的一侧固定卡接有定位销。
前述的方便开锁的U型长梁锁中，所述锁体上对应通孔两端部的 位置处均连接有防水胶圈，防水胶圈上设置有防水压盖。
与现有技术相比，本发明改进了现有的U长梁锁，通过将锁体上的通孔套入U型的锁梁内，锁体内的定位件与锁梁上的卡齿配合进行锁定；锁体内设置有垂直于锁梁长度方向的锁芯，方便使用者正常开锁；垂直于锁体正面的锁芯转动能带动锁芯侧面上的齿片转动，齿片通过啮合的传动齿带动与通孔平行的转动块转动，转动块转动至不同角度能改变定位件对锁梁的锁定状态(震动并不能改变定位件与转动块之间的限位关系)，防盗性较强。此外，本发明可以是转动块转动一定角度后，转动块侧面的让位槽与定位件对正，从而使得定位件受力后能缩入让位槽内，进行开锁；当让位槽以外的位置与定位件对正时，定位件无法缩入，定位件的一端凸出在通孔内对锁梁进行限定，以此进行锁定；同时转动块可以通过锁体上对应封块位置处的空缺中装入，且封块和转动块相对的位置处均设有导向孔，导向孔内设置有转轴，能保证转动块始终能保持竖直，且转动较顺畅；锁体内设置有两个对称设置的定位件，使得锁体和U型的锁梁锁住时，整体锁定稳定性较强；锁体上对应定位件伸缩方向的位置处设有安装槽，定位件通过安装槽敲入安装槽内并卡接，安装较方便；安装完成后将槽盖敲入锁体侧壁对应安装槽的位置处，锁体装配封闭性较好；定位件可以是包括与安装槽配合卡接的外套筒，外套筒和安装槽卡接；外套筒内通过弹簧连接有异形舌头，使得异形舌头能在外套筒内伸缩，异形舌头的一端与卡齿配合卡接，异形舌头的另一端能滑动伸出外套筒并进入让位槽内；同时本发明也可以是直接通过转动块的转动带动定位件朝远离通孔的方向移动，从而将定位件的一端退出通孔内，从而对锁梁进行解锁；定位件可以是舌条，舌条的两端分别设有舌头和卡块，舌头的顶部为倾斜面，舌头的底面为水平面，使得舌头仅能单向移动后才能被压缩退出通孔；或者舌条上的卡块被转动块上的推块带动， 从而使舌头退出通孔内，进行解锁；锁体内设置有两个前后配合左右对称的舌条，左侧舌条上的卡块位于右侧舌条上卡块的右侧，且两个舌头之间的位置处连接有复位弹簧，复位弹簧能使舌条上的舌头位于通孔内；转动块上的两个推块位于两个卡块的之间，转动块转动时，两个推块能分别推动舌条上的两个卡块朝外侧移动(左侧舌条上的卡块向右移动，右侧舌条上的卡块向左移动，并压缩复位弹簧)，从而使两个舌头退出通孔内，进行解锁；当转动块回转时，两个舌条上的卡块在复位弹簧的作用下复位，两个舌头伸出在通孔内，进行锁定；锁体上对应定位件伸缩方向的位置处设有安装槽，定位件通过安装槽敲入安装槽内并卡接，安装较方便；安装完成后将槽盖敲入锁体侧壁对应安装槽的位置处，锁体装配封闭性较好；两种锁定方式的锁芯外侧套均可以设有锁芯套，锁芯套通过定位销与锁体固定，使得锁芯仅能通过配套钥匙相对锁芯套转动；锁体上对应通孔两端的位置处均连接有防水胶圈，防水胶圈上设置有与锁体卡接的防水压盖，使得锁体与锁梁锁定后，雨水或灰尘不容易从通孔处进入锁体内，防止内部零件生锈，延长使用寿命。因此，本发明不仅能够方便开锁，还具有防盗性能较好、装配较方便和使用寿命较长的优点。

具体实施方式
下面结合附图和实施例对本发明作进一步的说明，但并不作为对本发明限制的依据。
实施例1。方便开锁的U型长梁锁，构成如图1和2所示，包括U型的锁梁1和锁体2，锁梁1上设有多个卡齿3；所述锁体2上设有与锁梁1配合的通孔4，锁体2内设置有两个分别朝向两侧通孔4的定位件；每个定位件的一端部均与卡齿3配合设置，两个定位件之间的位置处设置有与通孔4平行的转动块5；转动块5的一侧设置有与锁梁1长度方向垂直的锁芯6，转动块5上朝向锁芯6一端固定有圆周分布的传动齿7，锁芯6的侧面固定有与传动齿7啮合的齿片8；所述转动块5转动至不同角度能改变定位件对锁梁1的锁定状态。
所述转动块5的侧面设有让位槽9，让位槽9与定位件配合设置；所述转动块5上远离锁芯6的一侧设置有与锁体2侧壁配合卡接的封块10，封块10和转动块5上均设有导向孔11，导向孔11内设置有转轴12；所述锁体2上对应定位件伸缩方向的位置处设有安装槽13，锁体2侧壁上对应安装槽13的位置处设置有槽盖14；所述定位件包括外套筒15，外套筒15内设置有异形舌头16，异形舌头16与外套筒15之间设置有弹簧17；所述锁体2上对应锁芯5的外侧滑动设置有锁芯套23，锁芯套23与锁芯5之间滑动设置；锁体2上对应锁芯套23的一侧固定卡接有定位销24；所述锁体2上对应通孔4两端部的位置处均连接有防水胶圈25，防水胶圈25上设置有防水压盖26。
工作原理：先加工制作定位件，将弹簧17和异形舌头16安装进入外套筒15内，然后将定位件通过锁体两侧面上的安装槽13敲入锁 体2内(两个通孔4之间的位置处)，再将槽盖14将锁体2上的安装槽13封闭；接着将锁芯6及其锁芯套23通过垂直于锁体2正面的方向插入，然后将定位销24敲入锁体2内使其将锁芯套23与锁体2固定；然后将转动块5与封块10上导向孔11内之间连接转轴12，然后将这个整体放入锁体2内，并将封块10与锁体2卡接。
当需要锁定物品时，锁芯6处于开启状态，异形舌头16能缩入转动块5侧面的让位槽9；将U型的锁梁1插入锁体2上的两个通孔4内，锁梁1上的卡齿3呈圆弧形，异形舌头16的一端呈外凸的圆弧形，锁梁1两个卡齿3之间的位置能将异形舌头16挤压进入锁体2内；当锁梁1上的卡齿3与异形舌头16对位时，异形舌头16能在弹簧17的作用下恢复并与卡齿3配合；锁梁1在通孔4内移动至适合位置时(异形舌头16与卡齿3配合)，然后转动锁芯6，锁芯6通过侧面的齿片8带动转动块5端部的传动齿7，使得转动块5转动，转动块5侧面的让位槽9移开，其他侧面将异形舌头16限位，使其无法向内收缩，锁定锁梁；由于转动块5和封块10相对的位置处均设有导向孔11，且导向孔11内设置有转轴12，使转动块5转动顺畅的同时不会发生偏位，开关锁较顺畅。
当需要解锁时，用钥匙转动锁芯6，使得锁芯6通过侧面的齿片8带动传动齿7转动，传动齿7能使转动块5上的让位槽9与异形舌头16相对，使得异形舌头16能缩入让位槽9内，异形舌头16的端部退出通孔4内。
锁体2上对应通孔4两端的位置处均连接有防水胶圈25，防水胶圈25上设置有与锁体2卡接的防水压盖26，使得锁体2与锁梁1锁定后，雨水或灰尘不容易从通孔4处进入锁体2内，防止内部零件生锈，延长使用寿命。
实施例2。方便开锁的U型长梁锁，构成如图3至6所示，包括 U型的锁梁1和锁体2，锁梁1上设有多个卡齿3；所述锁体2上设有与锁梁1配合的通孔4，锁体2内设置有两个分别朝向两侧通孔4的定位件；每个定位件的一端部均与卡齿3配合设置，两个定位件之间的位置处设置有与通孔4平行的转动块5；转动块5的一侧设置有与锁梁1长度方向垂直的锁芯6，转动块5上朝向锁芯6一端固定有圆周分布的传动齿7，锁芯6的侧面固定有与传动齿7啮合的齿片8；所述转动块5转动至不同角度能改变定位件对锁梁1的锁定状态。
所述转动块5转动能将定位件朝远离通孔4的方向拉动；所述锁体2上对应定位件伸缩方向的位置处设有安装槽13，锁体2侧壁上对应安装槽13的位置处设置有槽盖14；所述定位件为舌条18，舌条18的一端设有舌头19，舌条18的另一端部固定有卡块20；舌头19的顶面为倾斜面，舌头19的底面为水平面；所述转动块5上对应卡块20一侧的位置处固定有推块21；所述锁体2内设置有两个前后配合并左右对称设置的舌条18，两个舌条18端部的舌头19分别朝向两侧的通孔4，两个舌头19之间位置处设置有复位弹簧22；左侧舌条18上的卡块20位于右侧舌条18上卡块20的右侧；所述转动块5上的两个推块21位于两个卡块20的之间；所述锁体2上对应锁芯5的外侧滑动设置有锁芯套23，锁芯套23与锁芯5之间滑动设置；锁体2上对应锁芯套23的一侧固定卡接有定位销24；所述锁体2上对应通孔4两端部的位置处均连接有防水胶圈25，防水胶圈25上设置有防水压盖26。
工作原理：先加工制作定位件，将两个舌条18前后拼接并在两个舌条18的两个卡块20之间连接有复位弹簧22，再将定位件从锁体2一侧面上的安装槽13内放入锁体2，再将槽盖14将锁体2上的安装槽13封闭；接着将转动块5从锁芯6的位置处放入锁体2内，并使转动块5端部的推块21放入两个卡块20之间，且推块21的顶 端与舌条18底端平面贴合，防止定位件转动；最后将锁芯6及其锁芯套23通过垂直于锁体2正面的方向插入，然后将定位销24敲入锁体2内使其将锁芯套23与锁体2固定。
当需要锁定物品时，转动块5上的两个推块21位于两个卡块20的中部，舌条18端部的舌头19凸出在通孔4内；由于舌头19的顶面为倾斜面，舌头19的底面为水平面，而卡齿3的形状和舌头19的形状相同，当锁梁1从上往下插入通孔4时，卡齿3上的倾斜面和舌头19上的倾斜面接触能将舌头19压入锁体2内，而当锁梁1从下往上拉出通孔4时，卡齿3上的水平面与舌头19上的水平面接触，相互限位无法拉出，从而进行锁定。
当需要解锁时，用钥匙转动锁芯6，使得锁芯6通过侧面的齿片8带动传动齿7转动，传动齿7带动转动块5转动，转动块5转动时，位于两个卡块20中部的推块21同步转动，并与舌条18上的卡块20接触，并将左侧舌条18上的卡块20向右推动，右侧舌条18上的卡块20向左推动，压缩复位弹簧22，从而使两侧的舌头19均退出通孔4内，从而使得锁梁1能从通孔4内拉出，进行解锁。
锁体2上对应通孔4两端的位置处均连接有防水胶圈25，防水胶圈25上设置有与锁体2卡接的防水压盖26，使得锁体2与锁梁1锁定后，雨水或灰尘不容易从通孔4处进入锁体2内，防止内部零件生锈，延长使用寿命。
