Referring to fig. 1 to 4, the present invention discloses an european style lock core structure 10 with quickly replaceable pins, the european style lock core structure 10 includes a lock housing 100 and a lock core body 200 inserted in the lock housing 100 and capable of rotating relative to the lock housing 100, the lock core body 200 is provided with a key hole 210 for inserting a key and a pin hole 220 communicated with the key hole 210, the lock housing 100 is provided with a pin slot 110 corresponding to the pin hole 220, a bottom pin 310 is inserted in the pin hole 220, a top pin 320 matched with the bottom pin 310 and a spring 330 providing a restoring force for the top pin 320 are arranged in the pin slot 110, and the spring 330, the top pin 320 and the bottom pin 310 together form a pin assembly 300. It should be noted that the bottom pin 310 is a component in the lock cylinder which contacts with the key, and as the number of times of inserting and pulling the key increases, the wear of the bottom pin 310 increases, and the bottom pin is easy to fail, so that the replacement of the pin in the present invention actually means the replacement of the bottom pin 310 of the lock cylinder. The lock case 100 is further provided with a marble window 120 and a cover 400 capable of being opened and closed on the marble window 120, the edge of the marble window 120 is provided with a bayonet 121, the cover 400 is provided with an elastic arm 410 which is in concave-convex fit with the bayonet 121, when the lock cylinder body 200 is driven by a key to rotate until the marble hole 220 is communicated with the marble window 120, the bottom marble 310 enters the marble window 120, the cover 400 is disassembled, and the constraint of the cover 400 on the bottom marble 310 is released, so that the bottom marble 310 can be poured out of the marble hole 220, that is, the bottom marble 310 can be assembled and disassembled through the marble window 120.
Specifically, a row of ball holes 220 is formed in the lock cylinder body 200, a plurality of ball grooves 110 corresponding to the ball holes 220 one by one are formed in the lock casing 100, and a ball assembly 300 is disposed between each two corresponding ball holes 220 and the ball grooves 110. When a key is not inserted into the key hole 210, the ball holes 220 are aligned with the ball grooves 110 one by one, the spring 330 is in an extended state and pushes the driver pins 320, so that the driver pins 320 are inserted into the ball holes 220, and thus, the cylinder body 200 is difficult to rotate relative to the lock housing 100 under the constraint of the driver pins 320, thereby ensuring the reliability of the lock cylinder. When a key is inserted into the key hole 210, the lock teeth on the key press the bottom pins 310 to push the top pins 320 away from the pin holes 220, and after the top pins 320 completely exit from the pin holes 220, the key is rotated to drive the lock cylinder body 200 and the bottom pins 310 to synchronously rotate, so as to facilitate unlocking or replacing the bottom pins 310.
The sealing cover 400 is a plastic part formed by an injection molding process, the sealing cover 400 comprises a sealing cover body 420 and an elastic arm 410 arranged at the side of the sealing cover body 420, and the elastic arm 410 deforms when being subjected to external extrusion force and swings relative to the sealing cover body 420 so as to realize concave-convex matching and separation with the bayonet 121 and facilitate the disassembly and assembly of the sealing cover 400. In one embodiment, a plurality of bayonets 121 are respectively disposed on both sides of the pin window 120, and a plurality of elastic arms 410 correspondingly engaged with the bayonets 121 are disposed on the cover 400, so that stability and reliability of connection between the cover 400 and the pin window 120 are increased.

It should be noted that, in this embodiment, the pin tumbler window 120 is arranged on the arc surface outside the lock housing 100, and the bayonet 121 is designed to be a wedge-shaped structure, so that on one hand, the difficulty of arranging the bayonet 121 on the arc surface is reduced, and on the other hand, when the seal cover 400 is detached, a tool is conveniently inserted into the bayonet 121 and presses the protruding block 430, so as to further press the elastic arm 410 to deform. In this embodiment, the protrusion 430 on the elastic arm 410 is engaged with the bayonet 121, so that the cap 400 is limited in the length direction of the elastic arm 410 and the swing direction of the elastic arm 410, and the cap 400 is prevented from shaking in the pin window 120.
It should be noted that, in the present embodiment, the protrusion 430 further provides a force-receiving position for the elastic arm 410 during the process of removing the cover 400. In practical operation, tweezers with grooves on the inner side can be used to clamp the elastic arm 410, specifically, the tweezers are clamped on the cover 400, and the protrusions 430 on the two sides of the cover 400 are correspondingly embedded into the grooves of the tweezers, so as to avoid the slipping problem or the clamping injury to the elastic arm 410 during the clamping process of the tweezers, and thus, in the process that the tweezers are gradually clamped by an external force, the elastic arm 410 swings towards the direction close to the cover body 420 under the action of the tweezers, so as to smoothly take out the cover 400.
Referring to fig. 7, the edge of the sealing cover body 420 is provided with a position-avoiding groove 421, the position-avoiding groove 421 is used for accommodating the swinging elastic arm 410, that is, the position-avoiding groove 421 is used for providing a space for avoiding when the elastic arm 410 swings in a direction away from the bayonet 121, and the width of the position-avoiding groove 421 limits the swing range of the elastic arm 410 relative to the sealing cover body 420, so as to avoid the problem that the elastic arm 410 fails due to an excessively large swing amplitude.
Referring to fig. 2 and fig. 6, in an embodiment, the inner wall of the pin window 120 protrudes toward the direction close to the center of the pin window 120 to form a limiting platform 130 for receiving and limiting the installation position of the sealing cap 400, and a protrusion 422 abutting and matching with the limiting platform 130 is disposed on the avoiding groove 421 at a side close to the free end of the elastic arm 410, that is, the protrusion 422 is formed on the sealing cap body 420, and when the external pressing force applied to the elastic arm 410 is released, the bottom surface of the elastic arm 410 abuts against the limiting platform 130. In this embodiment, by providing the limiting platform 130 and designing the convex portion 422 abutting against the limiting platform 130 on the cover body 420, the cover 400 is limited in the depth direction of the marble window 120, and the problem that the cover 400 is difficult to remove due to the fact that the cover 400 falls into the inner cavity of the lock housing 100 is avoided. In addition, when the external extrusion force applied to the elastic arm 410 is released, the bottom of the elastic arm 410 is separated from the avoiding groove 421 or only part of the bottom of the elastic arm 410 is positioned in the avoiding groove 421, in this case, the sealing cap 400 is abutted to the limiting platform 130 through the convex part 422 and the elastic arm 410, the connecting part area of the sealing cap 400 and the limiting platform 130 is large, and the mounting stability of the sealing cap 400 in the marble window 120 is improved.
Further, a pair of limiting platforms 130 is disposed in the pin window 120, a pin dismounting channel 140 is formed between the two limiting platforms 130, two sides of the sealing cap body 420 are respectively provided with a convex portion 422, when the sealing cap 400 is covered in the pin window 120, the convex portions 422 and the elastic arms 410 are respectively abutted against the limiting platforms 130, and the sealing cap body 420 is embedded into the pin dismounting channel 140. Specifically, the whole sealing cover 400 is of a step-shaped structure, the width and the shape of the sealing cover body 420 are matched with those of the marble dismounting passage 140, when the sealing cover 400 covers the marble window 120, the sealing cover 400 is limited, and meanwhile, the sealing cover body 420 completely blocks the marble dismounting passage 140, so that external dust or water stain is prevented from entering the inner cavity of the lock shell 100 through the marble window 120, the problems that the rotation of the lock core body 200 is influenced by rusting or dust in the lock core are prevented, the reliability of the lock core is guaranteed, and the service life of the lock core is prolonged.
Referring to fig. 2, fig. 6 and fig. 8, the inner surface of the marble window 120 is provided with a receiving groove 150 near the top surface of the limiting platform 130, the receiving groove 150 is communicated with the bayonet 121, and the side of the elastic arm 410 near the bayonet 121 is provided with a fin set 440 clamped with the receiving groove 150. When the sealing cover 400 is inserted into the pin window 120 and the external pressing force acting on the elastic arm 410 is released, the elastic arm 410 resets and rebounds, so that the protrusion 430 on the elastic arm 410 is inserted into the bayonet 121, and meanwhile, the fin group 440 on the elastic arm 410 is inserted into the receiving groove 150, so that the sealing cover 400 is limited to be displaced along the length direction of the elastic arm 410 and along the swinging direction of the elastic arm 410, and simultaneously, the top surface of the limiting platform 130 and the side of the receiving groove 150 are jointly constrained, the sealing cover 400 is not easy to fall into the inner cavity of the lock housing 100 and fall off from the pin window 120 under the external vibration effect, and the mounting stability and reliability of the sealing cover 400 are further improved.
In one embodiment, the fin set 440 includes a first fin 441 and a second fin 442 sequentially disposed from a fixed end to a free end of the elastic arm 410, the first fin 441 and the second fin 442 are respectively located at two sides of the bump 430, and a height of a top surface of the first fin 441 and a height of a top surface of the second fin 442 are respectively less than or equal to a height of a bottom surface of the bump 430. In this embodiment, by providing the first fins 441 and the second fins 442, while the sufficient contact area between the fin set 440 and the accommodating groove 150 is ensured, the difficulty of the elastic arm 410 being elastically deformed when being subjected to an external pressing force is reduced. The height of the top surface of the first fin 441 and the height of the top surface of the second fin 442 are respectively less than or equal to the height of the bottom surface of the protrusion 430, so as to ensure that the protrusion 430 is always located in the bayonet 121 when the first fin 441 and the second fin 442 are inserted into the receiving slot 150, thereby ensuring the reliability of the engagement between the protrusion 430 and the bayonet 121. In an embodiment, the width of the first fin 441 is smaller than the width of the second fin 442, where the width of the first fin 441 and the width of the second fin 442 are referred to as dimensions of the first fin 441 and the second fin 442 in a direction perpendicular to the outer side of the elastic arm 410, the outer side of the elastic arm 410 is a surface of the elastic arm 410, which is in contact with the pin window 120, and the inner side of the elastic arm 410 is a surface of the elastic arm 410, which is away from the bayonet 121 and located in the avoiding groove 421. When the elastic arm 410 swings relative to the cover body 420, the swing amplitude of the elastic arm 410 close to the fixed end of the elastic arm 410 is smaller than the swing amplitude of the elastic arm 410 close to the free end of the elastic arm 410, and the width of the first fin 441 is smaller than that of the second fin 442, so that after the fin set 440 is embedded into the accommodating groove 150, the outer side of the first fin 441 and the outer side of the second fin 442 can be abutted against the inner side surface of the accommodating groove 150 adjacent to the bayonet 121, and the stability of the fin set 440 in cooperation with the inner side surface of the accommodating groove 150 is improved.
