When the lock 2 of the present invention is applied, when the key 4 is not inserted into the lock core group 3, the two sliders 33 will be driven by the elastic force of the springs 333 to be displaced toward each other. When the slider 33 reaches the convex portion 314, it is positioned by the resistance of the convex portion 314. At this time, the two sliders 33 are just merged together, so that the recessed hole 332 of the two sliders 33 is Together, a complete conical hole is formed and corresponds to the position of the perforation 343 of the cover 34. At this time, the key hole 321 of the lock 32 is hidden by the two sliders 33 and concealed. In this case, it is impossible to The keyhole 321 can be easily viewed, and the situation in which the keyhole 321 is inadvertently blocked by foreign objects can be prevented. Also, as shown in FIG. 5, when the key 4 is to be used for unlocking, the key lever 41 of the key 4 will first penetrate into the hole 343 of the face cover 34, and then the key lever 41 will form a conical cone 411. Further extend into the conical hole formed by the recessed hole 332 of the second slider 33, and then continue to push the key 4 forward again. At this time, the first slider 33 receives the cone at the front end of the key lever 41 411 is gradually pushed away, and is then separated by the second rib 44 and the third rib 45 of the key lever 41, and the key lever 41 is extended into the lock 32 located behind the two sliders 33 In the key hole 321, the key lever 41 is further extended along the key hole 321 into the key channel 322, and at this time, due to each lock groove on the second rib 44 and the third rib 45 The formation position of 46 is lower than the height of the center point of the cross section of the key lever 41. Therefore, when the key lever 41 travels, each of the lock bead grooves 46 on the second rib portion 44 and the third rib portion 45 does not interact with the two sliders 33. There is contact, so that the key lever 41 can smoothly slide with the second rib 44 and the third rib 45 when the key lever 41 travels. When the key lever 41 extends along the key hole 321 When the keyway 322 travels and reaches the positioning position, the key lever 41 can smoothly and completely penetrate into the lock core 31, and then the handle portion 42 of the key 4 can be rotated to unlock the lock core 31 action.

Conversely, when the key 4 is to be pulled out of the lock 31, the key lever 41 of the key 4 is gradually backward to exit the key channel 322 of the lock 31. Similarly, the second rib 44 and the third rib The position of each lock bead groove 46 on the portion 45 is lower than the height of the center point of the cross section of the key lever 41. Therefore, when the key lever 41 is retracted, each lock bead groove on its second rib 44 and third rib 45 46 will not be in contact with the second slider 33, so the smoothness of the key lever 41 when it is retracted can be maintained, and once the key lever 41 completely exits the lock 31, the second slider 33 is not subject to the key lever 41 If the resistance is lowered, the elastic extension of the spring 323 will drive the two sliders 33 to move closer to each other, so that the two sliders 33 are displaced again to reach the convex portion 314, and then the two sliders 33 are merged together and return to the lock. If the keyhole 321 of Ren 31 is hidden by the two sliders 33, the keyhole 321 will be protected from being blocked by foreign objects.

The effect of the application of the present invention is that the lock 2 of the present invention forms a base 311 by one end of the lock 31, and two sliders 33 are arranged in the accommodation space 313 in the base 311, and the sliders 33 And can be pulled by the elastic force of a plurality of springs 333; so when the key 4 is not inserted into the lock core 31 of the lock core group 3, the two sliders 33 will be driven by the elastic force of the springs 333 to be displaced toward each other Until the two sliders 33 meet and merge, the recessed holes 322 of the two sliders 33 are merged to form a complete conical hole, so that the keyhole 321 of the lock 31 is hidden and hidden by the two sliders 33 and protected. The key hole 321 is not blocked by foreign objects; when the key 4 is to be used for unlocking, the key lever 41 of the key 4 will first penetrate into the perforation 333 of the cover 33, and then each of the recessed holes 322 of the two sliders 33 will start. The cone 411 at the front end of the key lever 41 is gradually pushed away, and then the two sliders 33 are pushed and separated by the second rib 44 and the third rib 45 of the key lever 41 to make the key lever 41 smooth. Fully penetrate into the lock 31, and then turn the lock 31 by turning the handle 42 of the key 4 When the unlocking action is performed, and when the key lever 41 is to be withdrawn back, the second rib 44 and the third rib 45 will still maintain good sliding contact with the two sliders 33, so that the The smoothness of the key lever 41 when retracting, and once the key lever 41 completely exits the lock core 31, the two sliders 33 will soon merge and merge again, and then return to the key hole 321 of the lock core 31 covered by the two sliders 33. Conceal and restore to protect the keyhole 321 from being blocked by foreign objects.
