Definitions
- the present invention relates to a lock, and more particularly to an electric lock that utilizes pre-pressure stored energy to generate an impulse to overcome a pre-pressure.
- the cathodic electronically controlled lock is a kind of ordinary lock, which is often used for electronically controlled modification of the anode mechanical lock door, or with the anode mechanical lock to construct a security system with double unlocking.
- cathode electrical lock It is because of the state of the door that a pre-stress is applied to the lock. This pre-stress is either due to deformation of the door panel, or due to a pressure difference between the inside and outside of the door panel, or because the door opener inadvertently pushes the door panel. In short, an additional pre-pressure is applied between the rotary lock and the sliding stop, which increases the friction between them, so that the force generated by the electromagnet is insufficient to overcome the friction, resulting in failure of the electronically controlled unlocking.
- the afterburner includes a fixed cup, a movable cup, a steel ball, a three-stage push rod, a movable cup spring, and a push rod spring, as shown in FIG.
- the rotating cup lock is locked by the movable cup end in the fixed cup, and the structure of the movable cup is locked by the push rod and the steel ball, and the push rod is pushed by the small force, and the locking of the movable cup is released, and the weight is adjusted to ensure that it is received.
- the lock is smoothly unlocked when the pressure is applied (see Figure 21).
- this structure is also defective: when the rotary lock is under pressure, the pressure is transmitted to the movable cup, and the steel ball is pressed by the pusher cone surface, and is placed in the ring groove of the fixed cup and the ball hole of the movable cup to lock the activity. At the same time, the cup is squeezed by the edge of the ball hole of the movable cup. When the force is large enough, deformation will inevitably occur. The deformation of the steel ball increases the resistance of the push rod movement, which makes the activity of the movable cup difficult, and the rotation lock cannot be unlocked. That is to say, although this structure partially solves the problem that the door panel is difficult to unlock due to the pre-stress, but the pre-stress If you are too big, you can't open the lock.

Description
利用预压力储能产生冲量克服预压力的电控锁
技术领域
本发明涉及锁具, 特别涉及一种利用预压力储能产生沖量克服预压力的 电控锁。
背景技术
阴极电控锁是一种普通锁具, 常用来已经装有阳极机械锁门的电控化改 造, 或者是与阳极机械锁共同构建具有双重开锁方式的安保***。
在设计、 生产、 使用中, 阴极电控锁最常遇到、 而又难以克服的下面所 述情况: 就是由于门的状态, 给锁具施加了一个预压力。 这个预压力或者是 由于门板的变形, 或者是由于门板内外的压力差, 或者是由于开门人不经意 地推拉门板。 总之一个额外的预压力施加到了旋转锁扣和滑动档柱之间, 这 就加大了其间的摩擦力, 以至于, 电磁铁产生的力量不足于克服该摩擦力, 从而造成电控开锁失败。
为解决此问题, 出笼了不少的方法, 但都没能 4艮好地解决这个问题。 通 常国外要求在 30kg 的预压力下能够顺利开锁, 大多数的阴极电控锁是达不 到这个要求的。
我公司在 2009年 6月 23日提交的申请号为 200919953634.2的专利申请 《一种门授予压状态下开启的门锁结构》 中提出的一种加力方案, 也存在一 些问题。 该加力方案包括固定杯、 活动杯、 钢球、 三段式推杆、 活动杯弹簧 和推杆弹簧, 可见图 21。 其中用固定杯中的活动杯端头锁定旋转锁扣, 用推 杆、 钢球锁定活动杯的结构, 通过较小的力量推动推杆, 解除对活动杯的锁 定的办法, 四两拨千斤, 确保在受到预压力时顺利开锁(见图 21 )。 但是这 个结构也有缺陷: 当旋转锁扣受到压力时, 会把压力传递给活动杯, 钢球受 推杆锥面挤压,处在固定杯的环槽和活动杯的球孔中,锁定了活动杯的同时, 受到活动杯球孔边沿的挤压, 力量足够大时必然发生形变, 钢球的形变增大 了推杆移动的阻力, 造成活动杯活动不易, 旋转锁扣无法解锁的现象。 就是 说, 尽管这套结构部分解决了门板受到预压力难以开锁的问题, 但在预压力
过大的情况下同样打不开锁。

本发明利用预压力储能产生沖量克服预压力的电控锁, 包括外壳 1、 旋 转锁扣 2、 变力器 4、 和电控装置 6。
旋转锁扣 2为异型条状, 一侧有滑动档柱凹面 21 , 另一侧两端有同心轴 孔 23 , 旋转锁扣 2的一端有垂直板 24, 上有锁凹 22 (见图 14 ) 。 在旋转锁 扣 2该侧、 装有滑动档柱 3。 滑动档柱 3为圓柱体, 一端有锥形台 31 , 另一 端有弧形凸 32, 弧形凸 32外有边台 33 (见图 15 )。 旋转锁扣 2通过同心轴 孔 23安装在外壳 1的旋转锁扣槽 11 , 以同心轴孔 23为轴可以翻开, 滑动档 柱 3上的锥形台 31正好压在锁凹 22之中, 这种状态为锁死状态。
变力器 4包括筒形外壳 41、 筒形内筒 42和止回推杆 46 (见图 16 ) , 内 筒 42的外径和外壳 41的内径相等, 倒扣在外壳 41中, 止回推杆 46为三段 式杆状, 头粗尾细中段为锥形, 粗端外径和内筒 42内径相当, 置于内筒 42 中, 细段从外壳 41底部伸出, 在止回推杆 46和内筒 42底之间装有推杆弹 簧 48, 内筒 42口壁和外壳 41底之间装有内筒弹簧 47, 外壳 41内壁上设有 环形槽 44, 内筒 42近口处设有若干个球孔 45 , 其中安放有钢球 43 , 在内筒 42伸出长度时球孔 45中钢球 43正好落在环形槽 44中, 此时, 止回推杆 46 的粗段顶住钢球 43 , 内筒 42无法回缩。 内筒 42的端部正好顶着滑动档柱 3 的弧形凸 32, 迫使滑动档柱 3另一侧的锥形台 31压入旋转锁扣 2侧面的锁 凹 22中, 使得旋转锁扣 2无法旋转, 达到锁具锁死的目的。
变力器 4受力端, 加装预压力转储装置 5和击锤 8 (见图 3、 图 5、 图 13 ) 。 预压力转储装置 (5 ) 包括滑杆 51 (见图 11、 图 12、 图 13 ) , 滑杆 51—端设有长击锤槽 55 , 另一端设有拨杆槽 53 , 其内有挂轴 54, 长击锤槽 55的一侧有滑动槽 56 (见图 11 ) , 其中安装击锤 8的安装轴 85和套在其上 的扭簧 86 (见图 12、 图 13 ) , 扭簧(86 ) 两臂分别压在击锤 8上的扭簧槽 84和滑杆 5的槽后挡 55a之间。 击锤 8的内面为斜面 82 (见图 11 ) 。 滑杆 51用固定块 50卡在外壳 1上, 可以在其中滑动, 滑杆 51上推杆片 57里面 有台阶, 该台阶和固定块 50之间装有回位簧 50a, 负责滑杆 51的回位。 滑 杆 51—侧设有推杆片 57, 推杆片 57和击锤 8—侧的弧形台 88重合, 在滑 杆 51回位时, 推动击锤 8回位。
拨杆槽 53下方设有偏心拨杆 52 (见图 11、 图 12 ) , 偏心拨杆 52的固 定轴 58固定在外壳 1相应位置, 其上的拨槽 59卡在挂轴 54上, 其下方的 凸棱 60卡在旋转锁扣 2边上的滑动档柱 3的边台 33上(见图 5、 图 3 ) , 击锤 8下端有挡凸 83 , 搭在电控转换装置 7上, 电控转换装置 7连接电控装 置 6。 另要求滑动档柱 3和变力器 4的内筒 42的端面(即出力端)之间留有 lmm左右的间隙,以保证在有预压力的情况下,滑动档柱 3有个滑动的余地, 以驱动滑杆 51去产生储能过程。 该间隙也可以放在变力器 4中。
电控转换装置 7由调节段 71、 固定段 72和复位簧 9组成, 固定段 72为 T字形, 横臂一端设有复位簧柱 73 , 上套复位簧 9, 竖臂上设有第一帽孔 77
和第二帽孔 78 ,调节段 71为台阶状, 对应位置设有第一螺孔 75和第二螺孔 76, 窄段一侧有垂直突出的击锤擎 74 (见图 7 ) , 挡住击锤 8的挡凸 83。 在 图 8状态中, 是第二帽孔 78和第二螺孔 76对准, 用螺釘固定。
电控装置 6包括电磁铁 61、 转动杠杆 63和长杆 64, 电磁铁 61的铁芯 62连接转动杠杆 63的一端, 转动杠杆 63的另一端连接长杆 64, 长杆 64的 另一端压在电控转换装置 7中的固定端 72横臂的另一端(见图 3、 图 10 ) 。
外壳 1上设有旋转锁扣槽 11 , 同侧还有装饰护挡 12 (见图 6 ) 。
当旋转锁扣 2受到预压力时, 旋转锁扣 2向外翻, 通过锁 22和滑动 档柱 3的锥形台 31传递到滑动档柱 3上,迫使滑动档柱 3向左移动(见图 5 ), 滑动档柱 3的边台 33拨动偏心拨杆 52, 偏心拨杆 52的转轴 58靠下, 其上 端的拨槽 59行程增加, 带动滑杆 51右移, 槽后挡 55a压迫扭簧 86, 使扭簧 86蓄力储能。 这套预压力转储装置 5不仅可以把预压力转换成能量储存, 而 且可以有效的减轻滑动档柱 3对内筒 42的压力,也就避免了钢珠 43的变形, 避免了由于钢珠 43 变形而带来的开锁失效问题。 由于该间隙不大, 旋转锁 扣 2只能稍稍外翻一点, 不会开锁。
开锁时, 电磁铁 61吸合, 电磁铁芯 62带动转动杠杆 63—端转动, 另 一端顶着长杆 64左移 (见图 3 ) , 顶动电控转换装置 7的固定段 72的 T字 形横臂下端与其连接的调节段 71的端头上翘, 其一侧的击锤擎 74脱离击锤 8端头的挡凸 83 , 扭簧 86发力, 带动击锤 8击打变力器 4的止回推杆 46的 尾部 (变力器 4的受力端) , 由于榔头效应产生的击打力远大于静压力, 足 以推动推杆 46向变力器 4中推进, 其锥形段脱离钢球 43底部, 钢球 43脱 出环形槽 44, 内筒 42失去支撑, 处于自由滑动状态; 此时旋转锁扣 2压迫 滑动档柱 3 , 滑动档柱 3压迫内筒 42, 由于内筒 42已经处于自由滑动状态, 顺利缩回, 旋转锁扣 2便可顺利打开, 实现开锁。
开锁后, 旋转锁扣 2失去压力, 在其内部弹簧的作用下自行复位, 滑动 档柱 3在内筒弹簧 47和滑杆 51回位簧 50a的共同作用下复位, 并重新回到 和内筒 42端面有间隙的位置。滑杆 51在回位簧 50a的作用下复位,复位时, 其上的推杆片 57推动击锤 8复位。 内筒 42在内筒弹簧 47的作用下复位, 而随着击锤 8的复位, 止回推杆 46在推杆弹簧 48的作用下复位, 钢珠 43
重新定住内筒 42的位置。 在电磁铁 61失去电源后(电控锁是在实现开锁后 就断电) , 由于击锤 8上的挡凸 83 已经复位, 电控转换装置 7在复位簧 9 的作用下复位, 并带动电控装置 6中的长杆 64复位, 击锤擎 74重新回到击 锤 8端头的挡凸 83下, 挡住击锤 8。 一切恢复原位。
在没有预压力的情况下, 电磁铁 61吸合, 电磁铁芯 62带动转动杠杆 63 一端转动, 另一端顶着长杆 64左移, 顶动电控转换装置 6的固定段 72的 T 字形横臂下端与其连接的调节段 71的端头上翘, 其一侧的击锤擎 74脱离击 锤 8端头的挡凸 83 ,滑杆 51通过扭簧 86带动击锤 8压迫变力器 4的止回推 杆 46的尾部, 由于没有预压力,静压力即可压动推杆 46向变力器 4中推进, 其锥形段脱离钢球 43底部, 钢球 43脱出环形槽 44; 此时旋转锁扣 2压迫滑 动档柱 3 , 滑动档柱 3压迫内筒 42, 由于内筒 42失去钢球 43的阻挡, 顺利 缩回, 旋转锁扣 2便可顺利打开, 实现开锁。
以上过程都是通电开锁情况。
在有的国家、 或者有的情况下, 要求断电必须开锁, 电控转换装置 7就 是为此而设。 上述图 8说明中, 是第二帽孔 78和第二螺孔 76重合, 用螺釘 固定, 实现通电开锁状态; 如果要求断电开锁, 只需要松开第二帽孔 78和 第二螺孔 76上的螺釘, 将调节段 72扭动, 使第一帽孔 77和第一螺孔 75重 合, 上紧螺釘即可 (见图 9 ) 。 此时调节段 72和固定端 71有个角度, 在断 电, 长杆 64复位时, 调节段 71—侧的击锤擎 74顶住击锤 8端部的挡凸 83 , 实现开锁;反之通电时,长杆 64顶出,击锤擎 74脱离击锤 8端部的挡凸 83 , 是锁死状态。 通过调整调节段 72和固定段 71的不同组合, 即可筒单地解决 一锁两用即可选择通电开锁, 也可选择断电开锁。
