Description

防松安全锁 技术领域
本发明涉及机车门锁， 是一种防松安全锁。
背景技术
现有机车门锁主要用于火车等金属门板， 这些锁具的基座内一般设有三角形钥匙孔， 锁 芯与锁舌连接， 通过三角形钥匙转动锁芯， 使门板打开和关闭， 其具有结构简单、 安装使用 方便、 生产成本低的特点， 广泛地应用于各种机车。 另一些机车门锁安装于门板或门框， 通 过锁芯的螺纹与门板 （或门框） 连接， 转动锁芯使门板与门框脱离或连接， 其通过锁芯的螺 纹与门板连接方式达到防松、 防振、 安全、 稳定的效果， 也具有结构简单、 安装使用方便、 生产成本低的特点， 也广泛地应用于各种机车。 但上述两种机车门锁结构中的锁芯防松、 防 振、 安全、 稳定性较差， 容易由于锁芯振动而导致锁芯发生转动， 使锁芯或锁舌脱离门板， 特别是用于动车、 高速列车等振动较大的振动式机械设备时。
发明内容
为克服上述不足， 本发明的目的是向本领域提供一种防松安全锁， 使其解决现有同类产 品在机车等振动式机械设备中安全性、 稳定性较差的技术问题。 其目的是通过如下技术方案 实现的。
一种防松安全锁， 该安全锁包括螺母、 轻型弹性垫圈、 基座、 锁芯， 基座设有座螺纹段 和钥匙孔， 基座的钥匙孔内设有锁芯， 基座的座螺紋段设有螺母和轻型弹性垫圈。 该安全锁 通过螺母、轻型弹性垫圈将基座安装于机车门板， 锁芯与锁舌连接， 钥匙插入基座的钥匙孔， 转动锁芯， 带动锁舌转动， 打开和关闭机车门板； 或将基座安装于机车门板或门框， 锁芯的 螺纹与门板 （或门框） 的连接孔对齐， 钥匙插入基座的钥匙孔， 转动锁芯， 锁芯打开和关闭 机车门板。
其技术要点是所述锁芯的外径设有凸筋， 凸筋一侧的锁芯外径设有芯螺纹段， 另一侧的 锁芯设有芯钥匙端， 芯钥匙端设有芯孔， 芯螺纹段与凸筋之间设有弹孔， 弹孔与芯孔相通， 弹孔内设有弹子， 芯孔内设有弹簧、 按钮杆； 所述按钮杆一端的弹簧端套入弹簧， 另一端为 杆钥匙端， 弹簧端至杆钥匙端之间的按钮杆外径依次设有浅槽段、 深槽段、 密封槽， 密封槽 内设有杆密封圈； 杆密封圈防止灰尘进入锁芯的芯孔， 影响芯孔内按钮杆、 弹子的使用。 所 述锁芯的芯螺纹段端套入、 穿过基座， 通过锁芯的凸筋固定、 止动于基座内； 弹簧、 按钮杆 的弹簧端依次套入锁芯的芯孔， 按钮杆的杆钥匙端露出于芯孔； 芯孔内的弹子一端与基座内 径相抵， 另一端与按钮杆的浅槽段或深槽端相抵； 弹子的两端分别呈弧形， 弹子与基座相抵 处的基座内径设有弧形槽。 ， 锁舌固定设置于锁芯的芯螺纹段， 钥匙插入基座的钥匙孔， 钥匙与锁芯的芯钥匙端外径 套合； 按压钥匙， 弹簧受力发生形变， 按钮杆向内移动， 弹子与按钮杆的浅槽段扣合变化为 弹子与按钮杆的深槽段扣合， 弹子脱离基座内径的弧形槽； 转动钥匙， 钥匙带动锁芯转动， 锁芯带动锁舌转动； 拔出钥匙， 弹簧带动按钮杆复位， 弹子重新回到按钮杆的浅槽段， 弹子 重新插入基座内径的弧形槽， 弹子与基座之间产生阻尼力， 即使利用其它工具转动锁芯， 锁 芯也不会转动。 或省略锁舌， 锁芯的芯螺纹段与门板 （或门框） 连接， 根据上述原理插入钥 匙， 转动锁芯， 锁芯的芯螺纹段与门板 （或门框）脱离， 门板打开； 锁芯的芯螺纹段与门板 (或门框） 连接， 门板关闭。
上述按钮杆的浅槽段和深槽段、 弹簧、 弹子的两端弧形、 基座内径的弧形槽， 以及通过 弹子配合按钮杆的浅槽段和深槽段设计， 即为该安全锁的防松安全装置。 通过该防松安全装 置使该安全锁在剧烈的振动下， 锁芯也不会转动、 松动， 只有在用钥匙按压按钮杆时， 才可 以转动锁芯； 该防松安全装置防止了机车等振动式机械设备在高速运转的过程中， 突然松动 而造成的安全隐患。 即该安全锁在自然状态时， 在弹簧作用下， 按钮杆处于抬起状态， 即按 钮杆的杆钥匙端露出于锁芯的芯孔状态， 按钮杆的浅槽段与弹子对齐， 弹子无法缩回， 弹子 卡在基座的弧形槽中， 使锁芯不能转动。 当按钮杆被按压时， 按钮杆的深槽段与弹子对齐， 弹子可自由滑动； 用钥匙旋转锁芯时， 弹子沿基座的弧形槽滑动， 自由旋转锁芯。
所述螺母设有螺钉孔， 螺钉孔内设有内六角锥端紧定螺钉， 内六角锥端紧定螺钉的锥端 与基座的座螺纹段啮合。 基座的座螺纹段通过螺母锁定后， 通过六角扳手转动内六角锥端紧 定螺钉， 使内六角锥端紧定螺钉的锥端与基座的座螺纹段啮合锁定。 由于螺母安装后不常拆 卸， 该方式在螺母基础上， 结合内六角锥端紧定螺钉， 提高了该安全锁的稳定性， 防止了螺 母的松动， 达到了基座防松的目的。
所述基座的弧形槽呈梅花形，弧形槽的梅花形设计方便了采用锁芯的芯螺紋段与门板（或 门框） 连接方式时， 通过钥匙按压按钮杆， 由钥匙带动锁芯转动。
所述锁芯的芯螺纹段采用梯形螺纹， 梯形螺纹升角小于摩擦角。 该芯螺纹段的螺纹设计 使锁芯的芯螺纹段具有自锁性， 进一步防止采用锁芯的芯螺纹段与门板 （或门框） 连接方式 时， 因振动造成锁芯与门板之间的松动。
所述锁芯的芯钥匙端呈多边形， 即如锁芯的芯钥匙端设计为三角形， 三角形凹槽端的钥 匙插入基座， 钥匙的三角形凹槽与锁芯的三角形芯钥匙端外径套合， 即可通过按压钥匙后转 动锁芯。
所述锁芯至少设有两组以上对称弹孔， 弹孔内分别对应设有弹子， 锁芯两组以上对称弹 孔设计， 提高了锁芯的稳定性。
所述锁芯上凸筋侧边锁芯设有弹孔， 凸筋与基座的连接处设有弹子挡圈。 上述设计使弹 子挡圈与弹子之间也产生阻尼力， 提高了弹子在按钮杆上浅槽段时的限位功能； 同时， 弹子 挡圈方便了带有弹子的锁芯装配入基座， 提高了弹子在弹孔内的稳定性。
所述锁芯与基座连接处设有座密封圈， 座密封圈防止灰尘通过基座与锁芯之间的间隙进 入门板内部。 基座的钥匙孔内径孔口设有钢丝挡圈， 钢丝挡圈防止锁芯从基座取出。
所述弹子与基座的内径之间设有小弹簧。 当钥匙按压按钮杆时， 小弹簧进一步方便弹子 插入按钮杆的深槽段； 按钮杆复位时， 按钮杆的浅槽段将弹子抵回原位， 小弹簧受力发生形 变。
所述锁芯的芯螺纹段外径设有锁紧圈， 通过锁紧圈使锁芯固定于基座， 并保证锁芯的转 动。
本发明设计合理， 结构简单， 安装、 使用方便， 应用范围广， 安全性、 稳定性好， 适用 于动车、 高速列车等各种机车， 以及振动式机械设备等同类金属门。

具体实施方式 、 现结合附图， 对本发明装配和使用作进一步描述。 如图 1、 图 2、 图 4所示， 轻型弹性垫 圈 3、 螺母 1依次从基座 4一端的座螺纹段 401套入基座， 设有内六角锥端紧定螺钉 2的螺 母旋入基座的座螺纹段。 基座内径的座螺纹段孔口设置座密封圈 5， 锁芯 7的凸筋 704—侧 芯螺纹段 701侧边锁芯分别对称设有弹孔 703， 弹孔内分别设置弹子 8， 弹子挡圈 6从芯螺纹 段套入锁芯， 弹子挡圈与锁芯的凸筋扣合， 弹子固定于锁芯。 按钮杆 10外径的密封槽 1004 内置入杆密封圈 11， 弹簧 9、 按钮杆的弹簧端 1001依次置入锁芯上芯钥匙端 702的芯孔， 带 有弹簧、 按钮杆的锁芯， 从锁芯的芯螺纹段套入、 穿过基座， 锁芯的芯螺纹段露出基座、 锁 芯， 并通过锁芯的凸筋固定、 止动于基座内。 由于芯孔与弹孔相通， 锁芯装入基座后， 按压 锁芯上的按钮杆， 当听到 "碰" 的一声， 弹子一端的弧形面插入基座内径的弧形槽， 另一端 的弧形面插入按钮杆的浅槽段 1002或深槽段 1003， 按钮杆的杆钥匙端 1005露出于锁芯的芯 孔， 该锁芯即可固定于基座内。 最后， 如图 6所示， 在基座的钥匙孔 402孔口设置钢丝挡圈 12， 该安全锁即可安装完成。
以该安全锁通过锁芯的芯螺纹段与机车的门板 （或门框） 连接为例。 安装时， 取下基座 上的轻型弹性垫圈和螺母， 将基座置入门板 （或门框） 的安装孔， 基座的座螺纹段套入轻型 弹性垫圈， 并旋入螺母。 当基座被轻型弹性垫圈、 螺母固定于门板 （或门框） 后， 通过六角 扳手旋紧螺母内的内六角锥端紧定螺钉，内六角锥端紧定螺钉的锥端与基座的座螺纹段锁定。 此时， 锁芯的芯螺纹段与门板 （或门框） 的连接孔对齐， 如图 4、 图 5、 图 7、 图 8所示， 弹 子一端的弧形端插入基座内径的弧形槽， 另一端的弧形面插入按钮杆的浅槽段， 即使机车严 重振动， 锁芯也无法转动。 钥匙 13插入基座， 钥匙的凹槽套入锁芯的芯钥匙端外径， 继续按 压钥匙， 如图 9、 图 10所示， 按钮杆露出芯孔的杆钥匙端插入芯孔， 弹簧发生形变， 弹子由 插入按钮杆的浅槽段转而插入按钮杆的深槽段。 此时， 通过钥匙转动锁芯， 弹子在基座内径 的梅花形弧形槽滑动， 锁芯的芯螺纹段与门板 （或门框） 的连接孔脱离， 门板打开； 锁芯的 芯螺纹段与门板 （或门框） 的连接孔连接， 门板关闭。 拔出钥匙， 如图 4、 图 5、 图 7、 图 8 所示， 弹簧带动按钮杆复位， 弹子重新插入按钮杆的浅槽段， 门板的打开或关闭状态保持不 变。
根据上述该安全锁的结构和使用说明， 结合现有机械锁的结构特征， 在弹子与基座之间 设置小弹簧， 或通过锁紧圈使锁芯的芯螺纹段固定于基座， 亦属于本发明的保护范围。 同时， 根据上述本发明的说明书内容， 对本发明作出本领域技术人员显而易见地结构改进， 亦将落 入本发明的保护范围。
