Description

一种箱包拉链密码锁 技术领域
本发明创造涉及锁具技术领域，具体涉及一种箱包拉链密码锁。
背景技术
为外出旅行的方便和安全，箱包上一般都设有箱包拉链密码锁，箱包拉链密码锁一般是通过数字密码或钥匙控制密码锁内锁钩的运动，进而使锁钩与箱包上的拉链头扣合或者脱离，从而实现箱包的上锁或解锁，箱包拉链密码锁操作便捷，安全可靠，适用范围非常广泛。
箱包拉链密码锁上一般都设有可用于施加外力的推制，推制可快速、方便、自动地实现密码锁的上锁或解锁。但是，现有技术中，推制设于箱包密码锁的端部，例如CN201310090233的专利公开了一种箱包拉链密码锁，其具体结构包括密码轮机构、锁钩、推制、活动片和锁芯，由于锁钩和推制分别设于密码锁的两端部，而密码轮机构设于锁钩与推制之间，在密码轮机构解锁时，数字密码正确，推制推动活动片滑动，进而活动片推动锁钩运动实现锁钩与拉链头的脱离，从而实现密码轮解锁；在钥匙解锁时，匙解插入锁芯内并带动锁芯转动，锁芯在转动的过程中推动活动片滑动，进而活动片推动锁钩运动实现锁钩与拉链头的脱离，从而实现钥匙解锁。由此可知，现有的箱包密码锁不管是采用密码轮锁机构解锁还是采用钥匙解锁，锁钩均需要通过活动片受控于推制或锁芯，而活动片的设置不仅使密码锁的结构和传动关系更为复杂，结构不紧凑，装配难度提高，生产成本增加，并且推制和锁芯均通过活动片控制锁钩的运动，使密码锁传动的稳定性和可靠性大大降低，尤其对于锁钩需要通过较长长度的活动片才能受控于推制和锁芯，不仅增大密码锁的体积，且大大降低密码锁的安全性能。

所述密码轮机构还包括由内而外依次套设在所述轮轴7的调码弹簧、调码轮8和密码轮9，所述密码轮9与所述调码轮8卡接且所述密码轮9带动所述调码轮8转动。
密码轮机构解锁时，数字密码正确，轮轴7可相对所述底壳1向右运动以解除对所述推制3向右运动的限制，向右推动所述推制3，所述推制3带动所述锁钩5向右运动以使所述锁钩5与拉链头脱离；钥匙解锁时，钥匙插入锁芯4并带动所述锁芯4转动，所述阻挡部40与所述挡板70错开，从而使推制3可朝右方向运动，向右推动所述推制3，所述推制3带动所述锁钩5向右运动以使所述锁钩5与拉链头脱离，同时所述锁芯4随同所述推制3向右运动。
具体的，所述轮轴7设有转动凹槽71和轴向贯穿所述转动凹槽71的滑动凹槽72，如图5所示，所述调码轮8的内圆周面设有凸块80。拨动密码轮9时，所述凸块80内置于所述转动凹槽71内且沿所述转动凹槽71滑动；重置密码或密码轮机构解锁时，所述凸块80内置于所述滑动凹槽72内且可沿所述滑动滑槽滑动。
具体的，为便于控制密码轮9拨动时的精准度，提高拨动密码轮9的质感，盖板13与密码轮9之间设有弹片14，弹片14的一端固定于所述盖板13，弹片14的另一端抵顶于密码轮9。
具体的，所述密码轮机构还包括调码块10和调码开关11，所述调码块10的一侧面抵接所述调码轮8，所述调码块10的另一侧面设有第一斜面100，所述调码开关11设有外露于所述面壳2的调码杆110和与所述第一斜面100配合的第二斜面111。
重置密码时，数字密码正确，按压所述调码杆110，所述调码开关11的第二斜面111通过所述第一斜面100压迫所述调码块10朝所述调码轮8方向运动，所述调码块10压迫所述调码轮8朝所述条码弹簧方向运动，同时所述凸块80内置于所述滑动凹槽72且沿所述滑动滑槽滑动；待重置密码完成后，松开所述调码杆110，所述调码轮8在所述 调码弹簧作用下自动复位。
本实施例中，如图4所示，所述面壳2设有用于拉链头穿过的锁钩孔20、用于所述推制3伸出的推制孔21、用于所述密码轮9伸出的密码轮孔22和用于所述调码杆110伸出的调码杆孔23。
具体的，所述面壳2还设有推制凹槽24，所述推制3内嵌于所述推制凹槽24且可沿所述推制凹槽24滑动，推制凹槽24的作用是使推制3的拨动面低于面壳2的上表面，这样在上锁时就能够有效防止因推制3和锁钩5之间的间距较小而导致不能上锁或者推制3与拉链头发生碰撞的情况发生，进而有利于缩短整个密码锁的长度。
具体的，所述面壳2还内置有挡块12，挡块12有两个且对称设于推制3的两侧，所述推制3与挡块12滑动连接且推制3可沿所述挡块12左右滑动，所述挡块12的两端均设有用于限制所述推制3滑动的限位凸台120。
最后应当说明的是，以上实施例仅用以说明本发明创造的技术方案，而非对本发明创造保护范围的限制，尽管参照较佳实施例对本发明创造作了详细地说明，本领域的普通技术人员应当理解，可以对本发明创造的技术方案进行修改或者等同替换，而不脱离本发明创造技术方案的实质和范围。
