发明人陈国强于2000年9月29日，申请了名为《角度匙防拨锁头》的实用新型专利，申请号为00239606.8。该角度匙防拨锁头，由钥匙、锁头及锁芯等组成，其特征是一个长方体形一面有槽口，槽口内有弹簧，一面下端有若干个圆锥体形销子的防拨插件镶嵌在锁芯的一侧内，圆柱体形的角度凸缘弹子嵌在与防拨插件成90°角的弹子孔内，角度凸缘弹子侧面有圆锥形孔，顶端有圆柱体销。该实用新型结构合理、组装简便、操作自如、安全可靠。但它仍有一定的弱点，即尚未突破用圆弹子作为锁芯的密码这个已有模式。Inventor Chen Guoqiang applied for a utility model patent named "Angle Key Anti-tear Lock" on September 29, 2000, and the application number is 00239606.8. The anti-dialing lock head of the angle key is composed of a key, a lock head and a lock cylinder, etc. It is characterized in that a rectangular parallelepiped has a notch on one side, a spring in the notch, and a number of conical pins on the lower end of one side. In one side of the lock cylinder, a cylinder-shaped angle flange pin is embedded in a pin hole at an angle of 90° with the dial-proof plug-in. The angle flange pin pin has a conical hole on the side and a cylinder pin on the top. The utility model has the advantages of reasonable structure, convenient assembly, free operation, safety and reliability. But it still has a certain weakness, that is, it has not yet broken through the existing mode of using the round marble as the password of the lock cylinder.
本实用新型的目的是提供一种防技术开启安全锁芯，推出一个全新的结构来代替传统的圆弹子，使克服已有技术的不足之处，有效地防止技术性开启，使钥匙的范围更广、更普及。The purpose of this utility model is to provide an anti-technical opening safety lock cylinder, and introduce a brand new structure to replace the traditional round marble, so as to overcome the shortcomings of the existing technology, effectively prevent technical opening, and make the key range wider , more popular.
本实用新型是这样构思的：要防止人为的技术性开启，同时摈弃沿用的圆弹子结构，发明人提出一种
字型的页片，在
字型页片一的侧有三角形缺口，不同页片其三角形缺口高度不相同，用页片来代替圆弹子这种结构上的新突破。在锁芯的中部安装多个字型的页片，页片的顶端连接有弹簧，弹簧顶住页片，使其下落到锁芯端面边缘。在锁芯的侧面垂直于页片的方向上开有防拨键槽，在防拨键槽里安装有前端为四面体与后端为长方体组合的长条形防拨键；防拨键的后端中部安装有弧形的定位块，定位块的两个端脚处连接有小弹簧，在防拨键的后端还安装了一根弓形钢丝，使防拨键在自由状态时能向锁芯的内部平移，防拨键前端的四面体尖端压向页片的侧面。当钥匙抽出时，页片在页片弹簧的压力下纷纷落向锁芯的边缘，页片的侧面同时就把防拨键推出锁芯的圆弧面，使防拨键卡在锁芯套上，这时使用任何技术性开启，拨动页片，都不能使锁芯转动，保证了该锁头的安全性。由于采用
字型页片，能够使钥匙的高度超过锁芯的圆截面中心线，因此钥匙的使用范围更为广泛，也更普及。The utility model is conceived in this way: in order to prevent artificial technical opening and abandon the used round marble structure at the same time, the inventor proposes a Font pages, in There is a triangular notch on the side of the font sheet one, and the height of the triangular notch is different for different sheets. It is a new breakthrough in the structure that the sheet is used to replace the round marbles. Install multiple font, the top of the leaf is connected with a spring, and the spring bears against the leaf so that it falls to the edge of the end face of the lock cylinder. On the side of the lock cylinder perpendicular to the direction of the leaf, there is an anti-dialing keyway, and in the anti-dialing keyway, a long bar-shaped anti-dialing key with a tetrahedron at the front end and a rectangular parallelepiped at the rear end is installed; the rear end middle of the anti-dialing key An arc-shaped positioning block is installed, and the two ends of the positioning block are connected with small springs, and a bow-shaped steel wire is also installed at the rear end of the anti-dialing key, so that the anti-dialing key can move toward the inside of the lock cylinder when it is in a free state. Translate, the tetrahedron tip at the front end of the anti-dialing key presses against the side of the leaf. When the key is pulled out, the leaves fall to the edge of the lock cylinder under the pressure of the leaf springs, and the side of the leaves push the anti-dialing key out of the arc surface of the lock cylinder at the same time, so that the anti-dialing key is stuck on the lock cylinder sleeve , At this time, using any technical opening and flipping the blades, the lock cylinder cannot be rotated, which ensures the safety of the lock head. Due to the use of The font-shaped sheet can make the height of the key exceed the center line of the circular section of the lock cylinder, so the key can be used in a wider range and is more popular.
本实用新型的优点是明显的：<一>采用
字型页片代替传统的圆弹子，结构新颖，坚固耐用；<二>钥匙的高度可以超过锁芯截面的中心线，因而钥匙范围广，更为普及。<三>可广泛用于各类锁具中。The advantage of the utility model is obvious: <one> adopts The font plate replaces the traditional round marble, which has a novel structure and is durable; <2> The height of the key can exceed the center line of the lock cylinder section, so the key range is wider and more popular. <3> Can be widely used in all kinds of locks.
下面依据附图进一步讲述本实用新型的结构。附图1为本实用新型的正剖视主视图；附图2为本实用新型的组装立体图；附图3为本实用新型的部件钥匙的立体图。Further describe the structure of the present utility model below according to accompanying drawing. Accompanying drawing 1 is the front sectional view of the present utility model; Accompanying drawing 2 is the perspective view of assembly of the present utility model; Accompanying drawing 3 is the perspective view of the component key of the present utility model.
附图我们得知：防技术性开启安全锁芯，包括锁芯1、防拨键4、防拨键槽9及钥匙8等部件，它的第一个结构特点是在锁芯，中部安装有一侧有三角形缺口10的
字型页片3。它的第二个结构特点是在
字型页片3的上端连接有页片弹簧2；前端为四面体和后端为长方体组合的长条形防拨键4连接在防拨键槽9中，防拨键槽9外端面上连接有弧形的定位块7，定位块7的内端面连接有小弹簧6，防拨键4后端上连接有弓形钢丝5。它的第三个结构特点是页片3可以是4～10片；页片3可以是
字型，也可以是“F”字型，也可以是“7”字型，三角形缺口10的顶点偏离页片3的中心线。它的第四个结构特点是钥匙8的顶部高度可以超过锁芯1的圆截面中心线，钥匙8的截面形状可以是牙花形，也可以是平板匙。From the accompanying drawings, we know that the anti-technical opening safety lock cylinder includes components such as lock cylinder 1, anti-dial key 4, anti-dial keyway 9 and key 8. Its first structural feature is that it is installed in the middle of the lock cylinder. Triangular notch 10's Font sheet 3. Its second structural feature is the The upper end of font sheet 3 is connected with leaf spring 2; Front end is tetrahedron and rear end is the elongated anti-dialing key 4 of cuboid combination and is connected in anti-dialing key groove 9, and anti-dialing key groove 9 outer end faces are connected with arc Shaped locating block 7, the inner end face of locating block 7 is connected with small spring 6, is connected with arcuate steel wire 5 on anti-dial key 4 rear ends. Its third structural feature is that the sheet 3 can be 4 to 10 pieces; the sheet 3 can be The font can also be "F" or "7", and the apex of the triangular gap 10 deviates from the center line of the sheet 3. Its fourth structural feature is that the height of the top of the key 8 can exceed the center line of the circular section of the lock cylinder 1, and the cross-sectional shape of the key 8 can be a tooth flower shape or a flat key.
本实用新型是这样运行的：当钥匙插入锁芯后，页片便随着牙花的不同高度相互配合，所有页片侧面的三角形缺口会在同一条直线上，而防拨键前端的条形四面体尖端受弓形弹簧的压力下会平移到页片的三角形缺口中，此时锁芯就成了整圆，再转动钥匙，锁芯会在锁头套中转动，锁即被打开。当抽出钥匙后，页片在弹簧的作用下，所有页片会位移到锁芯的截面边缘，同时防拨键也会被页片的侧面压力挤出向锁芯外圆面位移至突出于锁芯外圆面而卡阻在锁头套里，因此，<一>使用其它钥匙或技术性拨动都不可能使所有页片的三角形重合在一条直线上；<二>由于防拨键卡在锁头套里面，防拨键是一点也不能受外力(转动)才能自然弹向页片三角形缺口的，如稍有一点点外力(转动)它就会卡死在锁头套里。因此，锁是不会被开启的，它有力地防止撬动，以及技术性开启，十分安全。开发、应用此种防技术性开启安全锁芯具有更广泛的应用前景，必将创造电子的社会效益和经济效益。The utility model operates like this: when the key is inserted into the lock cylinder, the blades will cooperate with each other according to the different heights of the teeth, and the triangular notches on the sides of all the blades will be on the same straight line, and the bar-shaped gaps at the front end of the anti-dialing key will be on the same straight line. Under the pressure of the bow spring, the tip of the tetrahedron will translate into the triangular notch of the leaf. At this time, the lock cylinder becomes a full circle. Then turn the key, the lock cylinder will rotate in the lock head cover, and the lock will be opened. When the key is pulled out, under the action of the spring, all the leaves will be displaced to the edge of the cross section of the lock cylinder, and the anti-pull key will also be pushed out by the side pressure of the leaves to move to the outer surface of the lock cylinder to protrude beyond the lock Therefore, <1> it is impossible to make the triangles of all the leaves coincide on a straight line by using other keys or technical shifting; <2> because the anti-dialing key is stuck in the lock cover Inside, the anti-dialing key can not be subjected to external force (rotation) at all and can naturally bounce to the triangle gap of the leaf, as a little bit of external force (rotation) it will be stuck in the lock cover. Therefore, the lock will not be opened, and it effectively prevents prying and technical opening, which is very safe. The development and application of this kind of anti-technical opening safety lock cylinder has wider application prospects and will certainly create electronic social and economic benefits.
