The connecting seat 6 and the inserting rod 7 are integrated with the lock core seat 4, and the positioning steel ball 46 is set in the positioning hole 45 of the lock core seat 4, and a part of the positioning steel ball 46 is also set in the connecting seat 6 through the arc-shaped groove 62, and set the limit bead 44 in the groove 43 of the lock core seat 4, set the fixed sleeve 8 on the lock core seat 4, and set the compression spring 3 in the lock In the chamber 23 of the main body 2, the above-mentioned components combined with the lock core seat 4 are set in the chamber 23 of the lock body 2, so that the lower end of the plug rod 7 is stretched through the compression spring 3 And penetrate into the through hole 24 of the lock body 2, and a part of the limit bead 44 is set in the limit groove 28 of the lock body 2, and the connecting seat 6 is held against the compression spring 3, and then the fixed sleeve The flange 81 of 8 is embedded in the slot 26 of the lock body 2, the fixed sleeve 8 is fixed on the lock body 2, and the lock core seat 4 and its assembled components are positioned in the chamber of the lock body 2 23, another end 90 of the chain 9 is set in the first slot 20 of the lock body 2, and then the fixing bolt 22 is sequentially inserted into the perforation 201 of the lock body 2, one end 90 of the chain 9 and the positioning slot 200, the tooth pattern 220 of the fixing bolt 22 is tight in the perforation 201, so that the fixing bolt 22 will not escape from the perforation 201, and by virtue of the fixing bolt 22, one end 90 of the chain 9 is fixed to the first cut of the lock body 2. slot 20, and the other end 91 of the chain 9 is set in the second slot 21 of the lock body 2, and can be inserted downwards into the other end 91 of the chain 9 and the insertion slot 210 by means of the insertion rod 7. , the other end 91 of the chain 9 can be positioned in the second slot 21 of the lock body 2, so that the overall assembly can be completed.

使用时，请参阅第五～八图所示，将本发明的链条9穿绕于欲锁固的物品上，如自行车的车架或车轮上，再将链条9的另一端91插设入锁具本体2的第二切槽21内，使链条9的另一端91对正于锁具本体2的插挚孔210与通孔24位置(如图5所示)，再将外凸的锁心座4向锁具本体2内压入，其锁心座4带动锁心5、卷簧64、连接座6及插挚杆7下移，并将压缩弹簧3予以压持，使压缩弹簧3呈弹性压缩状态，而穿设于锁具本体2的通孔24内的插挚杆7下端部则穿设入链条9的另一端91并插设入锁具本体2的插挚槽210内，将锁心座4下压时，其锁心座4的定位孔45内的定位钢珠46则随之下移，并位于锁具本体2的定位槽27内，因锁心座4受限位珠44的限制而无法旋转，故卷簧64呈弹性回复时，其另一端641则将连接座6带动旋转，又因连接座6上设有弧形穿槽62，定位销48位于该弧形穿槽62内，故连接座6受卷簧64带动旋转时，其锁心5及插挚杆7则不会被带动，而连接座6受卷簧64的弹性回复带动下，其弧形穿槽62则脱离与锁心座4相对应的定位孔45位置，使连接座6的外壁面抵持住设于锁心座4的定位孔45内的定位钢珠46，将定位钢珠46向外抵推，定位钢珠46的一部分则外移嵌设至锁具本体2的定位槽27内(如图6所示)，如此，即可完成锁扣动作，本发明凭借定位钢珠46的嵌设定位，以及插挚杆7的插扣，可将链条9的另一端91稳固的锁扣于锁具本体2的第二切槽21内(如第七、八图所示)，本发明的锁具本体2外部无任何销孔设置，窃贼由外观无法得知其内部锁扣结构，故可确实达到最佳的防盗功效；当欲解扣时，仅需以钥匙(图中未示)插设入锁心座4的钥匙插孔40内，使钥匙深入锁心5内，以钥匙带动锁心5转动时，锁心5并凭借固定销54来连动连接座6转动，当连接座6转动时，连接座6则带动卷簧64呈弹性扭转状态，其连接座6的弧形穿槽62则再次与锁心座4的定位孔45相对应，嵌设于锁具本体2的定位槽27内的定位钢珠46因不再受连接座6的外壁面抵持，则得以沿着定位槽27的圆弧面向内被推移至连接座6的弧形穿槽62内，不再嵌持于锁具本体2的定位槽27内，而同时设于锁具本体2的容室23内的压缩弹簧3则呈弹性回复将连接座6及锁心座4向上顶推(如图5所示)，使锁心座4的上部凸伸出锁具本体2外，其插挚杆7则随锁心座4上移而脱离锁具本体2的插挚槽210及链条9的另一端91，链条9则可自锁具本体2的第二切槽21内取出，如此，即可完成解扣动作，本发明在使用上非常方便，可供任何物品的锁扣定位，具有极佳的防盗功效。When in use, please refer to the fifth to eighth figures, the chain 9 of the present invention is threaded around the object to be locked, such as the frame or wheel of a bicycle, and then the other end 91 of the chain 9 is inserted into the lockset In the second slot 21 of the body 2, make the other end 91 of the chain 9 align with the insertion hole 210 and the through hole 24 of the lock body 2 (as shown in Figure 5), and then place the outwardly protruding lock core seat 4 Press into the lock body 2, the lock core seat 4 drives the lock core 5, the coil spring 64, the connecting seat 6 and the plug rod 7 to move down, and presses the compression spring 3, so that the compression spring 3 is in an elastic compression state , and the lower end of the insertion rod 7 that is installed in the through hole 24 of the lock body 2 is inserted into the other end 91 of the chain 9 and inserted into the insertion groove 210 of the lock body 2, and the lock core seat is inserted 4 times. When pressing, the positioning steel ball 46 in the positioning hole 45 of its lock core seat 4 then moves down thereupon, and is positioned in the positioning groove 27 of the lockset body 2, because the lock core seat 4 is restricted by the limit ball 44 and cannot rotate, Therefore, when the coil spring 64 returns elastically, the other end 641 will drive the connecting seat 6 to rotate, and because the connecting seat 6 is provided with an arc-shaped slot 62, the positioning pin 48 is located in the arc-shaped slot 62, so the connecting seat When 6 is driven by the coil spring 64 to rotate, its lock core 5 and inserting rod 7 will not be driven, and the connecting seat 6 is driven by the elastic recovery of the coil spring 64, and its arc-shaped groove 62 is separated from the lock core seat. 4 Corresponding to the position of the positioning hole 45, the outer wall surface of the connecting seat 6 bears against the positioning steel ball 46 located in the positioning hole 45 of the lock core seat 4, pushes the positioning steel ball 46 outward, and a part of the positioning steel ball 46 is Move outward and be embedded in the positioning groove 27 of the lock body 2 (as shown in Figure 6), so that the locking action can be completed. , the other end 91 of the chain 9 can be firmly buckled in the second slot 21 of the lock body 2 (as shown in the seventh and eighth figures), and the lock body 2 of the present invention does not have any pin holes outside, so the thief can Its internal lock structure cannot be known from the appearance, so it can indeed achieve the best anti-theft effect; when it is desired to unlock, it is only necessary to insert a key (not shown) into the key socket 40 of the lock core seat 4, Make the key go deep into the lock core 5, and when the key drives the lock core 5 to rotate, the lock core 5 will rotate the connecting seat 6 with the help of the fixed pin 54, and when the connecting seat 6 rotates, the connecting seat 6 will drive the coil spring 64 to be elastic. In the twisted state, the arc-shaped groove 62 of the connecting seat 6 corresponds to the positioning hole 45 of the lock core seat 4 again, and the positioning steel ball 46 embedded in the positioning groove 27 of the lock body 2 is no longer supported by the connecting seat 6. When the outer wall is resisted, it can be pushed inward along the arc surface of the positioning groove 27 into the arc-shaped through groove 62 of the connecting seat 6, and is no longer embedded in the positioning groove 27 of the lock body 2, but is also located in the lock. The compression spring 3 in the chamber 23 of the main body 2 then elastically returns to push the connection seat 6 and the lock core seat 4 upward (as shown in Figure 5), so that the upper part of the lock core seat 4 protrudes out of the lock body 2, Its insertion rod 7 moves up with the lock core seat 4 and breaks away from the insertion groove 210 of the lock body 2 and the other end 91 of the chain 9, and the chain 9 can be self-locked from the lock itself. Take it out from the second slot 21 of the body 2, so that the unlocking action can be completed. The present invention is very convenient in use, can be used for locking and positioning any article, and has excellent anti-theft effect.
