Description
发明涉及一种锁具，尤其涉及一种弹子锁。 The invention relates to a lock, and more particularly to a pin lock.
弹子锁(Pin Tumbler
Lock)，亦称弹珠锁、珠锁、锁簧锁或销栓锁，是其中一种最常见的锁具结构。以往原理是使用多个不同高度的圆柱形零件（称为弹簧、弹子或珠），锁住锁芯，具体结构如图1，其包括它包括锁体1和锁芯2，锁体与锁芯内设有多列上弹子3，上弹子上部设有弹簧4，上弹子下部设有下弹子5，锁体和锁芯接触部为周界6，锁芯转动轴心为中心线7。当放入正确的钥匙，各上弹子和下弹子之间的夹缝位与锁芯和锁体间的周界对齐，锁芯便被放开，能转动。图1仅仅以双排弹子作说明，安全性更低的还有单排弹子再此不予描述。如图2，未放入钥匙的时候，锁内的上弹子(亦称上锁簧,
平头弹子或上珠等)往下推，令锁芯不能转动；如图3，放入正确的钥匙，上弹子、下弹子之间的夹缝位成一直线，与锁芯和锁体间的周界对齐，此时能转动，便能带动其它机械部件使锁打开或锁上。Pinlock (Pin Tumbler
Lock), also known as pinion lock, bead lock, lock spring lock or pin lock, is one of the most common lock structures. The conventional principle is to use a plurality of cylindrical parts of different heights (called springs, marbles or beads) to lock the lock cylinder. The specific structure is shown in Figure 1. It includes the lock body 1 and the lock cylinder 2, the lock body and the lock cylinder. There are a plurality of rows of upper marbles 3, a spring 4 is arranged on the upper part of the upper bullet, and a lower marble 5 is arranged on the lower part of the upper marble. The contact portion of the lock body and the lock cylinder is a perimeter 6, and the rotation center of the lock core is a center line 7. When the correct key is placed, the gap between the upper and lower marbles is aligned with the perimeter between the lock cylinder and the lock body, and the lock cylinder is released and can be rotated. Figure 1 shows only the double-row marbles, and the single-row marbles with lower safety are not described here. As shown in Figure 2, when the key is not placed, the upper marble inside the lock (also known as the upper lock spring,
Push the flat head or the upper ball, etc., so that the lock cylinder cannot rotate; as shown in Figure 3, put the correct key, the gap between the upper and lower marbles is in a straight line, and the perimeter between the lock cylinder and the lock body Alignment, which can be rotated at this time, can drive other mechanical parts to open or lock the lock.
在目前的弹子锁中,下弹子在可转动的状态下是不会越过中心线的，所谓中心线是指在锁芯转动时,
锁芯的旋转轴线。如图3,锁芯2转动时下弹子是不通过中心线7的。In the current pin lock, the lower ball does not cross the center line in a rotatable state, and the so-called center line means that when the lock cylinder rotates,
The axis of rotation of the lock cylinder. As shown in Fig. 3, the lower marble does not pass through the center line 7 when the lock cylinder 2 is rotated.
上述现有的弹子锁具有以下缺陷：1.由于上弹子和下弹子运动方向单一，在锁芯和锁体相对转动状态时上弹子和下弹子只能作由锁芯向锁体的运动，使技术开锁的人很容易在拔动弹子时感觉到上弹子和下弹子之间的夹缝位是否成一直线，与锁芯和锁体间的周界是否对齐；2.
由于上弹子和下弹子运动方向单一，很容易用”铝箔” 进行开锁；3.钥匙的组合变化相对较少，以图1为例，5 列的排布，每列能单一方向有5 级上下移动，也就是说有5
的5 次方组合，5x5x5x5x5=3125
个组合，钥匙和锁之间容易出现互开的情况。上述缺陷的存在导致弹子锁的安全性太差，经常给人民的生命和财产带来很大的损害。The above existing bullet lock has the following defects: 1. Since the upper and lower marbles move in a single direction, the upper and lower marbles can only be moved by the lock cylinder to the lock body when the lock core and the lock body are relatively rotated. The person who unlocks the technology can easily feel whether the gap between the upper and lower marbles is in line when pulling the marble, and whether the perimeter between the lock cylinder and the lock body is aligned;
Since the upper and lower marbles move in a single direction, it is easy to unlock with "aluminum foil"; 3. The key combination changes are relatively small. Take Figure 1 as an example, 5 columns are arranged, each column can have 5 levels in a single direction. Move, that is, have 5
5th power combination, 5x5x5x5x5=3125
Combinations, keys and locks are prone to open each other. The existence of the above defects leads to the safety of the marble locks, which often causes great damage to the lives and property of the people.
本发明所要解决的技术问题是提供一种弹子锁，大大提高了安全性，保障人民的生命和财产免受侵害。 The technical problem to be solved by the present invention is to provide a bullet lock, which greatly improves safety and protects people's lives and property from infringement.

The uneven upper and lower distances are more and more worn when being quickly put in and pulled out, so that the "aluminum foil" can be effectively prevented from being unlocked, and the safety is greatly increased;
3.
以两排弹子组为例由于有一组或多组上弹子和下弹子在锁芯和锁体能相对转动状态时作由锁体向锁芯的运动，并且越过中心线。锁体向锁芯的运动方向最少也能多提供2
级的上下移动。也就是说有7 的5 次方组合，7x7x7x7x7=16807 个组合，大大减少钥匙和锁之间容易出现互开的机率，安全性大增。3.
Taking two rows of marbles as an example, one or more sets of upper and lower marbles move from the lock body to the lock cylinder when the lock core and the lock body are relatively rotatable, and cross the center line. The lock body can provide at least 2 more movement directions to the lock cylinder.
The level moves up and down. That is to say, there are 7 combinations of 5 powers, 7x7x7x7x7=16807 combinations, which greatly reduces the chance of mutual opening between the key and the lock, and the safety is greatly increased.
总之，本发明能大大提高安全性，保障人民的生命和财产免受侵害。In short, the present invention can greatly improve safety and protect people's lives and property from infringement.

下面结合附图对本发明的实施方式做进一步的说明。The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
参见图4、5和图7，本发明的弹子锁包括锁体1和圆柱形锁芯2，锁芯2安装在锁体1内。本发明的弹子锁具有至少两排弹子组，优选偶数排（如2、4、6…排等）弹子组（图4和5中示出的是2排弹子组）并且每排弹子组包括至少两列弹子列（如图4和5中示出A列、B列、C列等），图4和图5示出的是2排弹子组5列弹子列的情况。每一弹子列包括上弹子3、下弹子5、以及与上弹子3配合的复位弹簧4，锁体和锁芯接触部为周界6，锁芯转动轴心为中心线7。如图4和5所示，位于同一锁芯横切面上的上下两排弹子组是对顶设置的。在未放入正确的钥匙8前多列下弹子5中的部分列下弹子位于锁芯和锁体之间，即部分列的下弹子5穿过周界6，锁芯2与锁体1之间相对转动被阻止；在放入正确的钥匙后部分列的下弹子5发生运动，且部分列下弹子运动越过中心线7，最终所有的上弹子3和下弹子5之间的夹缝成一条直线，直线与锁芯2和锁体1间的周界6对齐，锁芯2与锁体1之间能相对转动。Referring to Figures 4, 5 and 7, the ball lock of the present invention includes a lock body 1 and a cylindrical lock cylinder 2, and the lock cylinder 2 is mounted in the lock body 1. The ball lock of the present invention has at least two rows of marbles, preferably even rows (e.g., 2, 4, 6, ..., etc.) of marbles (two rows of marbles are shown in Figures 4 and 5) and each row of marbles includes at least Two columns of marbles (such as columns A, B, and C are shown in Figures 4 and 5), and Figures 4 and 5 show the case of two rows of marbles in five rows. Each of the marble columns includes a top marble 3, a lower marble 5, and a return spring 4 that cooperates with the upper marble 3. The lock body and the lock cylinder contact portion are a perimeter 6, and the lock core rotation axis is a center line 7. As shown in Figures 4 and 5, the upper and lower rows of marbles located on the transverse plane of the same cylinder are placed against the top. Before the correct key 8 is placed, the sub-balls of the plurality of sub-balls 5 are located between the lock cylinder and the lock body, that is, the sub-balls 5 of the partial row pass through the perimeter 6, the lock cylinder 2 and the lock body 1 The relative rotation is prevented; after the correct key is placed, the lower part 5 of the column moves, and the part of the lower column moves past the center line 7, and finally the gap between all the upper 3 and the lower 5 is in a straight line. The straight line is aligned with the perimeter 6 between the lock cylinder 2 and the lock body 1, and the lock cylinder 2 and the lock body 1 are relatively rotatable.
所述复位弹簧4分为强弹簧和弱弹簧两种，在锁止状态时（如图4），插入锁芯中的上弹子3所对应的弹簧为强复位弹簧，未插入锁芯中的上弹子3所对应的弹簧为弱复位弹簧，A列中上方的弹簧为弱复位弹簧，下方的弹簧为强复位弹簧；B列中上方的弹簧为弱复位弹簧，下方的弹簧为强复位弹簧；C列中下方的弹簧为弱复位弹簧，上方的弹簧位强复位弹簧。同一排弹子组内强复位弹簧和弱复位弹簧的配置是随机配置的，而对顶的两个弹子列中强复位弹簧和弱复位弹簧是匹配设置的，也就是说，在对顶设置的某些弹子列内，一边为强复位弹簧，则另一边为弱复位弹簧，这样可以增加锁的安全性；当然也可以在某些列中设置强度相同的复位弹簧。当钥匙8插入锁芯2中而使弹子锁处于开启状态时（如图5），每排弹子组中至少有一个弱复位弹簧对应的下弹子5插入钥匙8的凹口并越过钥匙的中心线7，所有强复位弹簧对应的下弹子5均不越过钥匙的中心线7。The return spring 4 is divided into two types: a strong spring and a weak spring. In the locked state (as shown in FIG. 4), the spring corresponding to the upper marble 3 inserted into the lock cylinder is a strong return spring, and is not inserted into the lock core. The spring corresponding to the pin 3 is a weak return spring, the upper spring in the A column is a weak return spring, and the lower spring is a strong return spring; the upper spring in the B column is a weak return spring, and the lower spring is a strong return spring; The spring below the column is a weak return spring, and the upper spring is strong to return the spring. The configuration of the strong return spring and the weak return spring in the same row of marbles is randomly configured, and the strong return spring and the weak return spring of the two upper rows of the marbles are matched, that is, some set on the top In some of the marble columns, one side is a strong return spring, and the other side is a weak return spring, which can increase the safety of the lock; of course, it is also possible to provide a return spring of the same strength in some columns. When the key 8 is inserted into the lock cylinder 2 and the bullet lock is in the open state (as shown in FIG. 5), at least one weak return spring corresponding to each of the rows of marbles is inserted into the recess of the key 8 and passes over the center line of the key. 7. The lower marbles 5 corresponding to all the strong return springs do not cross the center line 7 of the key.
此外，为了阻止在钥匙8没插入锁芯2前，强复位弹簧进入到弱复位弹簧的空间中，致使钥匙8无法插入，同时也为了能使钥匙插入更容易，转动更容易，寿命更长，设有强复位弹簧的下弹子的顶端两侧设置有限位块9，限位块9用于限制强复位弹簧任何时候都不能不越过中心线。在钥匙8插入锁芯2后，下弹子5可以插入到钥匙的凹口中，也可以抵靠在钥匙的平面上。由于强复位弹簧和弱复位弹簧的随机排列，钥匙上的凹口的倾斜角度（如图6所示）相比现有技术可以增大，最大可为80度(见图6)。In addition, in order to prevent the strong return spring from entering the space of the weak return spring before the key 8 is inserted into the lock cylinder 2, the key 8 cannot be inserted, and the rotation is easier and the life is longer, in order to make the key insertion easier. A finite stop block 9 is disposed on both sides of the top end of the lower marble provided with a strong return spring, and the limit block 9 is used to limit the strong return spring from crossing the center line at any time. After the key 8 is inserted into the lock cylinder 2, the lower marble 5 can be inserted into the recess of the key or against the plane of the key. Due to the random arrangement of the strong return spring and the weak return spring, the angle of inclination of the notch on the key (as shown in Figure 6) can be increased compared to the prior art, up to 80 degrees (see Figure 6).
以上所述并非对本发明的技术范围作任何限制，凡依据本发明技术实质对以上的实施例所作的任何修改、等同变化与修饰，均仍属于本发明的技术方案的范围内。The above description is not intended to limit the technical scope of the present invention, and any modifications, equivalent changes and modifications made to the above embodiments in accordance with the technical scope of the present invention are still within the scope of the technical solutions of the present invention.
由于锁体（1）、圆柱形锁芯（2）以及弹子组等均能利用现有工艺实施量化生产，且组成的弹子锁可有效确保人们的生命、财产安全，大大提高安全性，因而本创造具有明显的工业实用性。
