Description

Technical Field

[0001] This utility model belongs to the field of lock technology, and in particular relates to a lock cylinder structure with multiple locking positions. Background Technology

[0002] A known lock cylinder structure has several lock plates inside the lock body, with an elastic element between each lock plate and the lock body. A lock sleeve is fitted over the lock body, and the lock sleeve has a locking hole. The elastic element pushes the lock plates with its elastic force so that their tops are locked into the locking hole, thus preventing the lock body from rotating. When a key is inserted, the key presses down on the lock plates to prevent them from locking into the locking hole, thus allowing the lock body to rotate smoothly. This structure is widely used in the market, but it can also be cracked by most lock picks.

[0003] In general, to improve the security of a user's lock, it is necessary to delay the time and cost for a thief to break the lock as much as possible, so that the thief will give up on his own initiative, or to attract public attention by spending too much time, so as to achieve the purpose of calling the police.

[0004] Therefore, a solution is needed to address the above problems.

[0005] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0006] To solve the above problems, the purpose of this utility model is to provide a lock cylinder structure with multiple lock positions. When the spring pushes the flange into the main lock hole, if a lock-picking tool is used to enter the spring hole and press the spring, the flange will not be stuck in the main lock hole and the lock body will rotate. In this way, the flange will be stuck into the secondary lock hole, thereby delaying the cracking time and reducing the cracking cost.

[0007] To achieve the above objectives, this utility model proposes a lock cylinder structure with multiple locking positions, including a lock body and a locking sleeve. The lock body houses a lock cylinder with several lock grooves. A spring and a spring plate are disposed within each lock groove. The spring abuts against the lock groove and the spring plate. The spring plate has a spring plate hole for a key to pass through. The spring plate has flanges at its top and bottom. The front end of the lock cylinder has an insertion hole for inserting a key. A limiting flange is provided on the inner side of the bottom of the insertion hole. The locking sleeve... Outside the lock cylinder, the locking sleeve has main locking holes on its upper and lower sides. The spring pushes the spring plate to make the flange engage in the main locking hole. The locking sleeve also has auxiliary locking holes on its upper and lower sides. The auxiliary locking holes are parallel to the main locking holes. The auxiliary locking holes have a stop in them, so that the auxiliary locking holes are discontinuous or shorter than the main locking holes, preventing the flange of the spring plate from being fully engaged in the auxiliary locking holes. The front end of the locking sleeve has a limiting groove, and the limiting edge is located in the limiting groove.

[0008] In one example, the number of secondary locking holes is two.

[0009] In one example, the reeds change their orientation at intervals so that the flanges alternately move upwards or downwards into the main locking hole or the secondary locking hole.

[0010] In one example, the bottom of the spring is provided with a lower flange. When the spring is pressed too much, the lower flange is engaged in the main locking hole or the secondary locking hole on the other side of the locking sleeve, so that the lock body cannot be rotated.

[0011] The multi-position lock cylinder structure proposed in this utility model can bring the following beneficial effects:

[0012] The spring pushes the flange into the main lock hole. When a thief uses a lock-picking tool to enter the spring hole and press each spring, the flange is not locked in the main lock hole. When the thief tries to rotate the lock body, the spring will push the flange into the secondary lock hole, causing the spring to be stuck in an inclined state. The thief needs to press the spring again to continue cracking the lock, thereby prolonging the time and increasing the cost of cracking the lock. When the correct key is inserted into the spring hole through the keyhole, the spring is compressed, causing the spring to descend and preventing the flange from getting stuck in the main lock hole. This allows the lock cylinder to rotate smoothly. The secondary lock hole is discontinuous or shorter than the main lock hole due to the blocking part. Therefore, when rotating the lock cylinder, the flange of the spring will not get completely stuck in the secondary lock hole. Some of the spring flanges rest against the blocking part, which prevents the key from being pulled out when the spring is tilted. This avoids the need for the lock cylinder to be rotated back to its original position so that the flanges of the springs are all stuck in the main lock hole before the key can be pulled out, thus preventing operational errors.

Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0040] like Figures 1-5 As shown in the figure, an embodiment of the present invention proposes a lock cylinder 11 structure with multiple locking positions, including a lock body 10 and a locking sleeve 20. A lock cylinder 11 is disposed inside the lock body 10. The lock cylinder 11 is provided with a plurality of lock grooves. A spring 12 and a spring plate 13 are respectively disposed in the lock grooves. The spring 12 abuts against the lock groove and the spring plate 13. The spring plate 13 has a spring plate hole 131 for a key to pass through. The top and bottom of the spring plate 13 are respectively provided with flanges 132. The front end of the lock cylinder 11 is provided with an inlet portion 14. The inlet portion 14 has a lock hole 141 for inserting a corresponding key, and the bottom inner side of the inlet portion 14 is provided with a limiting flange 142. The locking sleeve 20 is fitted over the lock cylinder 11. A main locking hole 21 is opened on the upper and lower sides of the locking sleeve 20. The spring 12 pushes the spring plate 13 to make the flange 132 fully engaged in the main locking hole 21. At least one secondary locking hole 22 is also opened on the upper and lower sides of the locking sleeve 20. The secondary locking hole 22 is parallel to the main locking hole 21. At least one stop is provided in the secondary locking hole 22, so that the secondary locking hole 22 is discontinuous or shorter than the main locking hole 21, so that the flange 132 of the spring plate 13 cannot be fully engaged in the secondary locking hole 22. A limiting groove 23 is recessed at the front end of the locking sleeve 20, and the limiting edge 142 is located in the limiting groove 23.

[0041] like Figures 6-10As shown, based on the above structure, specifically, the spring 13 pushes the flange 132 into the main lock hole 21 through the spring 12. When the thief uses the unlocking tool 30 to enter the hole of the spring 13 and press each spring 13, the flange 132 is not stuck in the main lock hole 21 and the lock body 10 is rotated. Attempting to rotate the lock body 10 will cause the spring 12 to push the flange 132 into the secondary lock hole 22, so that the spring 13 is stuck in an inclined state. The thief needs to press the spring 13 again to continue to crack the lock, thereby extending the time for the thief to crack the lock and increasing the cost of cracking the lock.

[0042] like Figures 11-13 As shown, when the correct key is inserted into the spring 13 hole through the keyhole 141, the spring 12 is compressed, causing the spring 13 to descend so that the flange 132 is not stuck in the main lock hole 21, thus allowing the lock cylinder 11 to rotate smoothly. The secondary lock hole 22 is discontinuous or shorter than the main lock hole 21 due to the blocking part 221. Therefore, when rotating the lock cylinder 11, the flange 132 of the spring 13 will not be completely stuck in the secondary lock hole 22. Part of the flange 132 of the spring 13 rests against the blocking part 221, which can prevent the key from being pulled out when the spring 13 is tilted. Therefore, the lock cylinder 11 needs to be rotated back to its original position so that the flange 132 of the spring 13 is all stuck in the main lock hole 21 before the key can be pulled out, thus avoiding operational errors.

[0043] like Figure 13 As shown, depending on the arrangement of the secondary lock hole 22 and its blocking part 221, there are multiple arrangements and combinations, which makes the position of the locking spring 13 vary, further increasing the difficulty for the thief to crack the lock, thereby delaying the thief's unlocking time and attracting the attention of the surroundings, thus forcing the thief to give up unlocking and improving the security of the lock body 10.

[0044] Depending on the number and position of the secondary locking holes 22, the position in which the flange 132 engages with the corresponding secondary locking hole 22 may vary, potentially triggering unexpected situations during the thief's cracking process and thus delaying the cracking time.

[0045] like Figure 4 As shown, there are two secondary lock holes 22, which can increase the difficulty for thieves to break the lock body 10 to a certain extent.

[0046] Furthermore, since the main lock hole 21 and the secondary lock hole 22 are connected on the upper and lower sides of the lock sleeve 20, the spring 13 can insert the flange 132 into the main lock hole 21 and the secondary lock hole 22 by facing upward or downward. When a thief uses the lock picking tool 30 to crack the lock, he / she needs to try to press the spring 13 upward or downward, which delays the thief's cracking time.

[0047] like Figures 2-4As shown, the spring 13 changes its direction at intervals so that the flange 132 can be inserted into the main locking hole 21 or the secondary locking hole 22 in an alternating single or double manner.

[0048] like Figure 4 As shown, the bottom of the spring 13 is provided with a lower flange 132. When the spring 13 is pressed too much, the lower flange 132 will be inserted into the main locking hole 21 or the secondary locking hole 22 on the other side of the locking sleeve 20, so that the lock body 10 cannot be rotated, thereby further increasing the security.

[0049] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
