Description

一种U型长梁锁 技术领域
本发明涉及一种长梁锁，特别是一种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，此类挂锁中的结构较为复杂，成本加高。因此，现有的U型长梁锁存在着开锁不方便、结构较复杂和成本较高的问题。
发明内容
本发明的目的在于，提供一种U型长梁锁。本发明不仅能够方便开锁，还具有结构简单和成本较低的优点。
本发明的技术方案：一种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，锁体内设置有朝向通孔的弹性定位件，弹性定位件的端部与卡齿配合设置；弹性定位件的一侧设置有与锁体垂直的锁芯，锁芯的侧面设有与弹性定位件配合设置的让位槽。
前述的一种U型长梁锁中，所述锁体内设置有两个分别朝向两侧通孔的弹性定位件，两个弹性定位件对称设置。
前述的一种U型长梁锁中，所述锁芯设置在两个弹性定位件之间 的位置处。
前述的一种U型长梁锁中，所述锁体侧面上对应弹性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。
前述的一种U型长梁锁中，所述弹性定位件包括与安装槽配合卡接的外套筒，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。
前述的一种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；锁芯套上对应两侧弹性定位件的位置处均设有开孔。
前述的一种U型长梁锁中，所述锁体上对应锁芯套的一侧固定卡接有定位销。
前述的一种U型长梁锁中，所述锁体上对应每个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型长梁锁，通过将锁体上通孔套入U型的锁梁内，锁体内的弹性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体的锁芯(锁芯垂直于锁体的正面)，方便使用者正常开锁；锁芯侧面设有与弹性定位件配合的让位槽，通过锁芯和弹性定位件来对锁梁进行锁定控制，结构简单且整体成本较低；当锁芯上的让位槽与弹性定位件对正时，弹性定位件会缩入让位槽内，从而使弹性定位件退出通孔内，进行解锁；锁芯侧面上其他没有让位槽的一侧与弹性定位件对正时，弹性定位件无法缩入，弹性定位件的顶部凸出在通孔内，进行锁定。此外，本发明中锁体内设置有两个分别朝向两侧通孔的弹性定位件，且两个弹性定位件对称设置，使得U型的锁梁的两侧均能与两个通孔内的两个弹性定位件锁定，锁定较稳定，防盗性较强；锁芯设置在两个弹性定位件之间的位 置处，使得锁芯上设有两个对称设置的让位槽，使得一个锁定能同时控制两个弹性定位件的锁定和解锁，结构简单，操作方便；锁体的侧面上对应弹性定位件伸缩方向的位置处设有安装槽，可以将弹性定位件通过安装槽装入锁体内，安装较方便；同时锁体侧壁上对应安装槽的位置处设置有槽盖，槽盖能将锁体密封，增加防盗性；弹性定位件包括外套筒，外套筒内设置有异形舌头，异形舌头和外套筒之间连接有弹簧，异形舌头的一端与锁梁上的卡齿配合，异形舌头的另一端可以收缩进入锁芯侧面的让位槽内，从而实现弹性定位件对锁梁的锁定和解锁；锁体上对应锁芯外侧滑动设置有锁芯套，锁芯套与锁芯之间滑动设置，锁芯套的一侧固定卡接有定位销，保证锁芯套能相对锁体固定；锁芯在锁芯套内转动，使得锁芯仅能通过配套钥匙相对锁芯套转动，从而使锁芯侧面两个让位槽和锁芯套两侧的开孔对正，让弹性定位件能缩入让位槽内；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。本发明仅能够方便开锁，还具有结构简单、成本较低、防盗性较强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。一种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内设置有朝向通孔4的弹性定位件，弹性定位件的端部与卡齿3配合设置；弹性定位件的一侧设置有与锁体2垂直的锁芯5，锁芯5的侧面设有与弹性定位件配合设置的让位槽6。
所述锁体2内设置有两个分别朝向两侧通孔4的弹性定位件，两个弹性定位件对称设置；所述锁芯5设置在两个弹性定位件之间的位置处；所述锁体2侧面上对应弹性定位件伸缩方向的位置处设有安装槽7，锁体2侧壁上对应安装槽7的位置处设置有槽盖8；所述弹性定位件包括与安装槽7配合卡接的外套筒9，外套筒9内设置有异形舌头10，异形舌头10与外套筒9之间设置有弹簧11；所述锁体2上对应锁芯5的外侧滑动设置有锁芯套12，锁芯套12与锁芯5之间滑动设置；锁芯套12上对应两侧弹性定位件的位置处均设有开孔13；所述锁体2上对应锁芯套12的一侧固定卡接有定位销14；所述锁体2上对应每个通孔4两端部的位置处均连接有防水胶圈15，防水胶圈15上设置有防水压盖16。
工作原理：先加工制作弹性定位件，将弹簧11和异形舌头10安装进入外套筒9内，然后将弹性定位件通过锁体两侧面上的安装槽7敲入锁体2内(两个通孔4之间的位置处)，再将槽盖8将锁体2上的安装槽7封闭；接着将锁芯5及其锁芯套12通过垂直于锁体2侧面的方向插入，然后将定位销14敲入锁体2内使其将锁芯套12与锁体2固定。
当需要锁定物品时，锁芯5处于开启状态(锁芯5上的两个让位槽6与锁芯套12上的开孔13对正)，异形舌头10能穿过开孔13缩入让位槽6内；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10的一端呈外凸的圆弧形，锁 梁1能将异形舌头10的另一端挤压进入让位槽6内；当锁梁1上的卡齿3与异形舌头10对位时，异形舌头10能在弹簧11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(且异形舌头10与卡齿3配合)，然后转动锁芯5，锁芯5上的让位槽6与开孔13错位，从而使异形舌头10无法缩入锁体2内，异形舌头10将锁梁1卡在通孔4内，完成锁定。
当需要解锁时，用钥匙转动锁芯5，使得锁芯5上的让位槽6与开孔13相对，异形舌头10一端能被压出通孔4，另一端进入让位槽6内，锁梁能在通孔4内移动，完成解锁。
锁体2上对应通孔4上下两端部的位置处均连接有防水胶圈15，防水胶圈15上设置有与锁体2卡接的防水压盖16，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。
