Description
技术领域technical field
本实用新型涉及弹子锁的锁头部件，特别是一种防破拆限位锁头。The utility model relates to a lock head part of a tumbler lock, in particular to an anti-tampering limit lock head.
背景技术Background technique
目前常见的的弹子锁的锁头部件结构如图6、7所示,包括锁芯套5和设在锁芯套上锁芯孔内的锁芯6。在锁芯套的弹子孔和锁芯的弹子孔内设有弹簧71、平头弹子72和半圆头弹子73,通过堵头将弹簧71、平头弹子72和半圆头弹子73封堵在锁芯套弹子孔及锁芯的弹子孔内。在钥匙槽61两侧的限位孔内分别安装有弹簧81及弹珠82,通过堵头将弹簧81及弹珠82封堵在限位孔内,弹簧81及弹珠82用来限制半圆头弹子73向下移动,依靠半圆头弹子73限制锁芯6转动。The structure of the lock head part of the common tumbler lock is shown in Figures 6 and 7, including a lock cylinder cover 5 and a lock cylinder 6 arranged in the lock cylinder hole on the lock cylinder cover. A spring 71, a flat-headed pin 72 and a semi-round pin 73 are arranged in the pin hole of the lock cylinder cover and the pin hole of the lock core, and the spring 71, the flat pin 72 and the semi-round pin 73 are blocked in the pin of the lock core sleeve by a plug. hole and the pin hole of the lock cylinder. A spring 81 and a marble 82 are respectively installed in the limiting holes on both sides of the key slot 61, and the spring 81 and the marble 82 are blocked in the limiting hole by a plug, and the spring 81 and the marble 82 are used to limit the semicircle The pin 73 moves downwards, and the rotation of the lock cylinder 6 is limited by the semi-round pin pin 73 .
该结构的锁头存在以下不足之处：There are following deficiencies in the lock end of this structure:
1、在锁闭状态下，由于弹珠82在限位孔内的伸缩距离很短，而限位孔两边对称且中间又隔着钥匙槽，因此在两个限位孔之间就存在较大空位。当有异物拨动时，弹珠82容易在弹簧81弹力的作用下跳到限位孔的外面，从而堵塞钥匙槽，使钥匙无法正常开锁。1. In the locked state, since the expansion and contraction distance of the marble 82 in the limit hole is very short, and the two sides of the limit hole are symmetrical and the key slot is separated in the middle, there is a large space between the two limit holes. bit. When a foreign matter is moved, the marble 82 is likely to jump out of the limit hole under the action of the elastic force of the spring 81, thereby blocking the key slot and making the key unable to unlock normally.
2、在闭锁状态下,弹簧81有一部分会暴露在钥匙槽中,若将末端呈钩形的钢丝伸入钥匙槽61中很容易将弹簧81勾出来,没有弹簧81的支撑,弹珠82缩回限位孔中,半圆头弹子73没有弹珠82的支撑也随之下落,再用异物拨动半圆头弹子73，使半圆头弹子73上端面下落至锁芯套弹子孔与锁芯弹子的交界处时,锁芯即可转动。2. In the locked state, a part of the spring 81 will be exposed in the key slot. If the hook-shaped steel wire at the end is inserted into the key slot 61, it is easy to hook the spring 81 out. Without the support of the spring 81, the marble 82 shrinks. Return to the limit hole, the semi-round pin 73 will fall without the support of the pin ball 82, and then use a foreign object to stir the semi-round pin 73, so that the upper end surface of the semi-round pin 73 will fall to the pin hole of the lock cylinder sleeve and the pinhole of the lock cylinder. At the junction, the lock cylinder can be turned.
综上所述，该结构的锁头抗破坏性能差，防盗性能差。In summary, the lock head of this structure has poor anti-destructive performance and poor anti-theft performance.

本实用新型与现有技术相比具有如下优点：Compared with the prior art, the utility model has the following advantages:
1、上弹子B均阶梯轴形,内弹子孔的孔径大于外弹子孔的孔径。该结构可使锁芯在闭锁的状态下，内、外弹子孔相连通形成一个“阶梯孔”，上弹子B其在“阶梯孔”中的活动范围受到限制，当上弹子B的台阶面抵住“阶梯孔”的台阶面时便无法再上抬，即上弹子B不会被异物整体抬升推入锁芯套的外弹子孔中，相比现有的锁头防盗性能得到加强。1. The upper pin B has a stepped shaft shape, and the hole diameter of the inner pin hole is larger than that of the outer pin hole. This structure can make the lock cylinder in the locked state, and the inner and outer pinholes are connected to form a "stepped hole". The range of movement of the upper pin B in the "stepped hole" is limited. When the step surface of the "ladder hole" is locked, it can no longer be lifted up, that is, the upper pin B will not be lifted by foreign objects and pushed into the outer pin hole of the lock cylinder sleeve. Compared with the existing lock head, the anti-theft performance is enhanced.
2、左、右安装孔均为阶梯孔，左、右弹子均呈阶梯轴形。该结构保证了无论在何种情况下，左、右弹子的活动范围都限制在左、右安装孔中，当左、右弹子的台阶面抵住左、右安装孔的台阶面时便已达到最大行程，不能继续向前移动，即左、右弹子不会被异物勾出来，也不会被异物拨弄而蹿到左、右安装孔外，进而堵塞钥匙槽，相比现有的锁头抗破坏性能得到提升。2. The left and right mounting holes are both stepped holes, and the left and right marbles are both in the shape of a stepped shaft. This structure ensures that under any circumstances, the range of movement of the left and right pins is limited to the left and right mounting holes, and when the step surfaces of the left and right pins are against the step surfaces of the left and right mounting holes, the The maximum stroke cannot continue to move forward, that is, the left and right marbles will not be hooked out by foreign objects, nor will they be fiddled with by foreign objects and jump out of the left and right mounting holes, thereby blocking the key slot. Destruction performance has been improved.
3、左、右安装孔互为一定夹角，且均为阶梯孔。从而钥匙槽插入异物后不能将左、右弹子上下连续拨动。3. The left and right mounting holes are at a certain angle with each other, and both are stepped holes. Thereby the left and right marbles cannot be continuously moved up and down after the foreign matter is inserted into the key slot.
4、左、右弹子的端头为球面，用异物插入钥匙槽盗锁时压在左、右弹子端头的球面上极易打滑，而无法将左、右弹子同时下压，增大了盗锁的难度。4. The ends of the left and right pins are spherical. When a foreign object is inserted into the key slot to steal the lock, it is easy to slip when pressed on the spherical surface of the ends of the left and right pins. The difficulty of the lock.
以下结合图和实施例对本实用新型作进一步描述。Below in conjunction with figure and embodiment the utility model is described further.
