The utility model relates to a U type lock, the lock body comprises a shell main part and the main parts of the lock body, lock the main parts arranged in the lock core, shifting block, slider and locking piece shifting block rotate with the lock core, and the linkage of the slider and the locking member in a fixed location in the main lock body the fork slider below the fork arm hold position slide fork, on the outside of the shell is provided an n-shaped fixing piece, an n-shaped piece is fixed on the upper end of the bolt hole and opened by the screw is connected with the casing, an n-shaped fixing piece on both sides of the wall by screws and lock the main piece. The utility model overcomes the friction block type U lock and lock the sliding between main parts, is not smooth, the assembly structure of the lock body is relatively complex, defective connection strength is not high, through the design, the positioning fork fork arm only supports the slider, greatly reducing the frictional resistance of the sliding. \An\ shaped fixing piece and the lock body is the main part and the shell are connected together, the assembly is convenient, has the advantages of simple and compact structure, stable operation, with the advantages of high strength.
【技术实现步骤摘要】
本技术涉及一种u型锁锁头。
技术介绍
传统的U型锁锁头, 一般都包括锁体主件和锁体主件外的壳体,锁体主件中设置 锁芯、拨块、滑块和锁定件,拨块随锁芯转动,并联动滑块和锁定件。上述结构的U型锁锁头 在动作过程中滑块和锁体主件间的摩擦力大,滑动也不平稳;同时上述U型锁锁头的锁体 的装配结构较复杂,生产效率低,而且连接强度也不高,在外力的冲击下容易破裂损坏,因 此其防盗性能也难以满足使用要求。
技术实现思路
为了克服现有技术中普通U型锁锁头的滑块和锁体主件间的摩擦力大,滑动不平 稳,锁体的装配结构较复杂,生产效率低,连接强度不高的问题,本技术提供一种U型 锁锁头,该U型锁锁头的结构紧凑、工作稳定、连接强度高、可靠性强。 本技术解决其技术问题所采用的技术方案是包括锁体主件和锁体主件外的 壳体,锁体主件中设置锁芯、拨块、滑块和锁定件,拨块随锁芯转动,并联动滑块和锁定件,在滑块下方的锁体主件中固定定位叉,定位叉的叉臂托住滑块。 在壳体外设置"门"形固定件,"门"形固定件的上端开设插闩孔并由螺钉与壳体相 连,"门"形固定件的两侧壁由螺钉与锁体主件相连。 锁体主件内两侧设有连接片,由"门"形固定件的两侧壁拧入的螺钉与连接片螺纹 连接。 锁体主件内的连接片上设有与插闩孔相对的插孔。 本技术通过上述具体设计,定位叉的叉臂托住滑块,大大减少了滑块滑动的 摩擦阻力,提高了工作的稳定性,强度增强的"门"形固定件将锁体主件和壳体连成一体,装 配也非常方便,具有结构简单紧凑、连接强度高、可靠性强的优点。以下结合附图和实施例说明本技术的详细内容。附图说明图1是本技术在开锁状态下的结构示意图 ...
