[0034] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0035] Reference Figures 1 to 7 This embodiment of the present invention includes a lock cylinder with a door magnetic module 400, comprising a base 100, a latch body 200, a dial drive mechanism 300, a door magnetic module 400, and a protective member 500. The base 100 has a receiving hole 101 along the front-to-back direction; the latch body 200 is retractably disposed in the receiving hole 101 along the front-to-back direction; the dial drive mechanism 300 is disposed on the base 100 and connected to the latch body 200, and is used to drive the latch body 200 to extend or retract; the door magnetic module 400 is disposed on the base 100, and has a conductor 410, part of which is located within the receiving hole 101; the protective member 500 is disposed on the base 100 and located within the receiving hole 101, and is located between the conductor 410 and the latch body 200, separating the latch body 200 and the conductor 410.

[0036] By adding a protective component 500 to the base 100, the lock tongue 200 and the wire body 410 are separated by the protective component 500. During the extension and retraction movement of the lock tongue 200 driven by the dial drive mechanism 300, the lock tongue 200 cannot directly contact the wire body 410 of the door magnetic module 400, so that the lock tongue 200 cannot wear down the wire body 410, making the door magnetic module 400 less prone to damage, thereby improving the service life of the lock cylinder.

[0037] In the embodiments, reference is made to Figure 1 and Figure 4 The receiving hole 101 has a wire outlet hole 102 on its wall, through which the wire body 410 extends out of the receiving hole 101. The wire outlet hole 102 is provided so that the wire body 410 can extend out of the receiving hole 101 at a suitable position, which facilitates the laying of the wire body 410 and improves the manufacturability of assembly production.

[0038] It is conceivable that in other embodiments, the conductor 410 may also be entirely located within the receiving hole 101.

[0039] In the embodiments, reference is made to Figure 3 and Figure 5 The protective component 500 has a wire receiving groove 501 on the side opposite to the locking tongue body 200, and the wire body 410 is embedded in the wire receiving groove 501. By providing the wire receiving groove 501 in the protective component 500, the wire body 410 can be embedded in the wire receiving groove 501, so that the wiring position of the wire body 410 can be defined by the wire receiving groove 501, avoiding the risk of messy wiring of the wire body 410 in the receiving hole 101, making the wiring position of the wire body 410 more stable, and making the layout between the protective component 500 and the wire body 410 more compact.

[0040] In the embodiments, reference is made to Figure 6 The protective component 500 includes an annular block 510 and a strip block 520. The annular block 510 surrounds the outer periphery of the latch body 200 and is connected to the base 100. One end of the strip block 520 is connected to the annular block 510, and the strip block 520 extends in the front-to-back direction and is located on one side of the latch body 200. Both the annular block 510 and the strip block 520 have wire receiving grooves 501. The annular block 510 makes the protective component 500 more securely installed on the base 100. The strip block 520 is set according to the laying direction of the wire body 410, using less material, which is conducive to a more compact internal structure of the lock cylinder and reduces material costs.

[0041] Specifically, the protective component 500 is made of plastic, which is relatively smooth and performs well.

[0042] When installing lock cylinders on doors, space constraints often necessitate the use of lock cylinders of varying lengths. Therefore, the following improvements have been made to make the lock cylinder length adjustable:

[0043] In the embodiments, reference is made to Figure 3 and Figure 6The dial drive mechanism 300 includes a dial member 310 and a transmission member 320. The transmission member 320 is slidably disposed on the base 100 in the front-back direction and connected to the locking tongue body 200. The dial member 310 is rotatably disposed on the base 100. The rotation axis of the dial member 310 is perpendicular to the front-back direction. When the dial member 310 rotates, it can drive the transmission member 320 to move. The locking tongue body 200 can adjust its position relative to the transmission member 320 in the front-back direction.

[0044] When the dial 310 rotates, it drives the transmission component 320 to slide in the front-to-back direction, thereby causing the bolt body 200 to extend and retract, thus realizing the locking and unlocking operations. The bolt body 200 can be adjusted in position relative to the transmission component 320 in the front-to-back direction, that is, the overall length of the transmission component 320 and the bolt body 200 can be adjusted, which is suitable for lock cylinders with different length requirements and improves versatility.

[0045] Specifically, the dial head 310 has a lever, and the transmission member 320 has a connecting hole. The lever passes through the connecting hole, and when the dial head 310 rotates, the lever drives the transmission member 320 to slide in the back-and-forth direction. It is conceivable that in some other embodiments, the dial head 310 may also be equipped with a gear, and the transmission member 320 may be equipped with a rack. When the dial head 310 rotates, the gear and rack structure drives the transmission member 320 to slide in the back-and-forth direction.

[0046] In the embodiments, reference is made to Figure 3 and Figure 7 The latch body 200 is movably connected to the transmission component 320. The latch body 200 is provided with a first connecting block 210, and the transmission component 320 is provided with a first spiral groove 321. The central axis of the first spiral groove 321 is arranged in the front-back direction, and the first connecting block 210 is slidably connected to the first spiral groove 321. When the latch body 200 is subjected to a rotational external force relative to the transmission component 320, the first spiral groove 321 guides the sliding direction of the first connecting block 210, causing the latch body 200 to undergo spiral motion relative to the transmission component 320. Since the central axis of the first spiral groove 321 is arranged in the front-back direction, the position of the latch body 200 relative to the transmission component 320 can be adjusted in the front-back direction. The adjustment method is simple and does not require disassembling the lock cylinder.

[0047] In the embodiments, reference is made to Figure 3 and Figure 7Both ends of the first spiral groove 321 are provided with first slots 322, and the first spiral groove 321 communicates with the first slots 322. When the latch body 200 rotates to its limit position relative to the transmission member 320, the first connecting block 210 enters the first slot 322 through the end of the first spiral groove 321, so that the latch body 200 no longer adjusts its position relative to the transmission member 320 in the front-to-back direction, and the overall length of the latch body 200 and the transmission member 320 can remain relatively stable for normal use. When it is necessary to readjust the position of the latch body 200 relative to the transmission member 320, the user can apply force to rotate the latch body 200, so that the first connecting block 210 disengages from the first slot 322, and then the first connecting block 210 can slide again along the first spiral groove 321 to adjust the overall length of the two.

[0048] In the embodiments, reference is made to Figure 2 and Figure 3 The base 100 includes an outer cylindrical shell 110 and an inner locking shell 120. The inner locking shell 120 passes through the outer cylindrical shell 110 in the front-back direction. The inner locking shell 120 and the outer cylindrical shell 110 form a receiving hole 101. The dial 310 is rotatably connected to the inner locking shell 120. The opening of the receiving hole 101 is located in the outer cylindrical shell 110. The protective member 500 is disposed in the outer cylindrical shell 110. The door magnetic module 400 includes a first door magnet 420. The first door magnet 420 is disposed in the outer cylindrical shell 110 and is connected to the wire body 410. The outer cylindrical shell 110 can be adjusted in position relative to the inner locking shell 120 in the front-back direction. The outer cylinder shell 110 is adjustable relative to the inner cylinder shell in the front-to-back direction, which means that the total length of the base 100 in the front-to-back direction can be adjusted. This is compatible with the adjustable total length of the lock tongue and transmission component 320, so that the overall length of the lock cylinder can be adjusted to meet the different door installation and usage requirements and improve the versatility of the lock cylinder.

[0049] Specifically, the first magnet 420 is the transmitter.

[0050] Specifically, the inner lock shell 120 is movably connected to the outer cylinder shell 110. The inner lock shell 120 is provided with a second connecting block 121, and the outer cylinder shell 110 is provided with a second spiral groove 111. The central axis of the second spiral groove 111 is arranged in the front-back direction, and the second connecting block 121 is slidably connected to the second spiral groove 111. When the outer cylinder shell 110 is subjected to a rotational external force, the second spiral groove 111 guides the sliding direction of the second connecting block 121, causing the outer cylinder shell 110 to undergo spiral motion relative to the inner lock shell 120. Since the central axis of the second spiral groove 111 is arranged in the front-back direction, the position of the outer cylinder shell 110 relative to the inner lock shell 120 can be adjusted in the front-back direction, thereby adjusting the overall length of the base 100 in the front-back direction. The method of adjusting the position is simple and does not require disassembling the lock cylinder.

[0051] In the embodiments, reference is made to Figure 1 and Figure 2 Both ends of the second spiral groove 111 are provided with second slots 112, which communicate with the second spiral groove 111. When the outer cylinder shell 110 rotates to its limit position relative to the inner locking shell 120, the second connecting block 121 enters the second slot 112 through the end of the second spiral groove 111, so that the outer cylinder shell 110 no longer adjusts its position relative to the inner locking shell 120 in the front-back direction, and the overall length of the outer cylinder shell 110 and the inner locking shell 120 can remain relatively stable for normal use. When it is necessary to readjust the position of the outer cylinder shell 110 relative to the inner locking shell 120, the user can apply force to rotate the outer cylinder shell 110, so that the second connecting block 121 disengages from the second slot 112. Then the second connecting block 121 can slide again along the second spiral groove 111 to adjust the overall length of the two.

[0052] Specifically, the first spiral groove 321 and the second spiral groove 111 have the same spiral direction. The outer cylinder shell 110 and the latch body 200 rotate synchronously, and the latch body 200 can slide relative to the outer cylinder shell 110 in the front-back direction. When the user rotates the outer cylinder shell 110, the outer cylinder shell 110, the guide wire 410, the protective member 500 and the latch body 200 rotate synchronously. This allows the outer cylinder shell 110 to adjust its position relative to the inner lock shell 120 in the front-back direction, while the latch body 200 also adjusts its position relative to the transmission member 320 in the front-back direction. This, in turn, adjusts the overall length of the lock cylinder, resulting in two different lock cylinder lengths suitable for applications with two different lock cylinder installation sizes.

[0053] Specifically, when the outer shell 110 rotates relative to the inner lock shell 120, the wire body 410 is embedded in the wire receiving groove 501, making it less likely for the wire body 410 to be contacted and worn by the inner lock shell 120.

[0054] It is understandable that the first connecting block 210 can also be located in the transmission member 320, and the corresponding first spiral groove 321 can be located in the locking tongue body 200. It is conceivable that the locking tongue body 200 can also achieve position adjustment relative to the transmission member 320 in the front-back direction through other structures. For example, the transmission member 320 can have multiple first pin holes arranged in the front-back direction, and the locking tongue body can have a second pin hole. By switching between the second pin hole and any one of the first pin holes, the locking tongue body 200 can be adjusted in the front-back direction relative to the transmission member 320.

[0055] It is understandable that the second connecting block 121 can also be provided in the outer shell 110, and the corresponding second spiral groove 111 can be provided in the inner lock shell 120. It is conceivable that the outer shell 110 can also achieve position adjustment relative to the inner lock shell 120 in the front-back direction through other structures. For example, multiple third pin holes are arranged in the front-back direction in the inner lock shell 120, and a fourth pin hole is provided in the outer shell 110. By switching the insertion of a pin into any of the third pin holes and the fourth pin hole, the position of the outer shell 110 can be adjusted relative to the inner lock shell 120 in the front-back direction.

[0056] Specifically, the base 100 also includes an end plate 130, the front end of the outer shell 110 is mounted on the end plate 130, the end plate 130 has an opening, the protective member 500 is clamped between the end plate 130 and the outer shell 110, and one end of the protective member 500 is inserted into the opening, so that the protective member 500 is mounted on the base 100.

[0057] Specifically, the outer shell 110 is provided with a positioning protrusion, and the inner lock shell 120 has a positioning hole. When the outer shell 110 rotates to the limit position relative to the inner lock shell 120, the positioning protrusion is inserted into the positioning hole, so that the position between the outer shell 110 and the inner lock shell 120 is not easily loosened.

[0058] Specifically, the door lock also has a latch socket 600, which has a latch slot. The latch socket 600 is installed on the door frame, and the lock cylinder is installed on the door. The latch socket 600 is equipped with a second door magnet 430 corresponding to the first door magnet 420. The first door magnet 420 is a transmitter, and the second door magnet 430 is a permanent magnet.
