Description

Technical Field

[0001] The invention relates to the technical field of blade locks, and in particular to a method for changing an unlocking channel of a blade lock. Background Art

[0002] The insert lock usually includes a lock core, an insert, and a lock core sleeve. The lock core is provided with a plurality of insert slots. The insert is usually installed in the insert slot with a reset spring. The lock core is provided with a lock hole, and a through slot is provided on the insert. When the key is not inserted into the lock core, the spring pushes up the insert, so that a part of the insert extends out of the outer periphery of the lock core and is limited by the lock core sleeve set on the outer periphery of the lock core, so that the lock core cannot rotate; when the correct key is inserted into the lock hole, the key passes through the through holes with through slots on each insert in turn, driving the insert to move and compress the reset spring, so that the insert is returned to the insert slot and no longer limited by the lock core sleeve, and the lock core is unlocked. By turning the key, the lock core can be driven to rotate to unlock or close. Only when the correct key is inserted can the insert be completely returned to the lock core slot. At this time, the channel determined by the through slots of each insert is the unlocking channel, and the contour of the unlocking channel fits the contour of the key.

[0003] In order to improve the anti-theft effect, a lock usually matches a key. However, since the plug-in lock is widely used on various door cabinets, the demand is large. In the prior art, different locks usually need to be designed with different keys. After determining the key contour, the different sizes and positions of the through slots on the plug are calculated and designed according to the key contour, resulting in a large amount of calculation and design, which is not conducive to large-scale production. It often leads to a limited number of types of plug-in locks on cabinet doors. The keys matching the plug-in locks of different manufacturers can even be used universally, which loses the anti-theft effect. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a method for changing the unlocking channel of a plug-in lock in view of the deficiencies of the above-mentioned prior art. The method adjusts the sorting method of the processed plugs, that is, arranges and combines the plugs to determine the contours of different unlocking channels. When the contour of the unlocking channel is determined, the contour of the key can also be determined. After the contour is determined, the key matching it is processed, thereby greatly reducing the amount of calculation and design. As the number of plugs increases, the ways of arranging and combining the plugs increase, thereby combining more diverse channel contours to avoid the situation where keys are universal and improve the anti-theft effect.

[0005] To achieve the above object, the present invention provides the following technical solution: a method for changing the unlocking channel of a blade lock, characterized in that it comprises the following steps:

[0006] S1: Process a lock core, one end of which is processed with a lock hole, and the outer circumference of the lock core is sequentially provided with a plurality of slots of the same specification and connected to the lock hole in a direction away from the lock hole; manufacture a plurality of return springs that can be installed in the slots; manufacture a plurality of groups of slots with the same outer contour that can be installed in the slots, the slots are provided with through slots, and the slots are divided into a plurality of categories according to the size and position of the through slots; a plurality of slots of each category are provided, and the number of slot slots is the same as the number of slots; let the total number of slots be n;

[0007] S2: Each plug-in corresponds to each plug-in slot that is adapted to it and is sorted, and each plug-in slot is set to be the first plug-in slot, the second plug-in slot, and so on in order along the direction away from the key hole until the nth plug-in slot; initially, the plug-in corresponding to each plug-in slot is set to be the first plug-in slot, the second plug-in slot, and so on in order until the nth plug-in;

[0008] S3: proceed to step S4 or S5;

[0009] S4: reselect or re-enter parameter x and parameter y, requiring 1≤x≤n, 1≤y≤n, x≠y; then, select the x-number plug and the y-number plug in a direction away from the keyhole;

[0010] If the two plugs do not belong to the same type, the positions of the two selected plugs are exchanged; if the two plugs belong to the same type, the parameter x or parameter y is reselected or re-entered;

[0011] S5: When the positions of the inserts are made to correspond to the positions of the insert slots and the projections of the outer contours of the inserts on the same plane overlap, the through grooves of the inserts form unlocking channels, and the contour of the key to be matched is determined according to the unlocking channels;

[0012] S6: Repeat step S4 or proceed to step S7;

[0013] S7: Install the insert and the return spring into the insert slot.

[0014] By adopting the above technical solution, the positions of the selected plug-ins are exchanged to achieve the arrangement and combination of the plug-ins. The through slots of the plug-ins naturally present different unlocking channels, thereby determining the contour of the key that matches the unlocking channel. Compared with the traditional method (i.e., determining the size and position of the through slot on the plug-in based on the key contour), the designer's calculation and design workload is reduced, and rapid production of multiple plug-in locks with different unlocking channels can be achieved to provide them to different manufacturers, and the situation of universal keys can be effectively avoided, thereby improving the anti-theft effect.

[0015] For S1, the outer contour of each plug can be designed to be of uniform specifications to facilitate replacement of each plug, and the plug slots that match the plugs can also be designed to be of uniform specifications. The slots of each plug can be opened at will, and plugs with the same slot size and opening position can be classified according to the slot size and opening position, that is, the slot size and opening position of each type of plug are the same. The total number of plugs can be designed according to requirements;

[0016] In S2, the insert slots and inserts are numbered, which is convenient for manual identification when the inserts are installed manually; when the inserts are installed by a machine such as a manipulator controlled by a computer program, it is convenient for computer programming;

[0017] When entering S3, you can choose to proceed to step S4 or S5. If you proceed to S5, the outline of the unlocking channel is determined according to the initial insert sequence, and then the key outline is determined; if you proceed to S4, the insert replacement step is performed. If the two selected inserts belong to the same type of inserts, that is, the through-slot size and opening position are the same, the unlocking channel outline will not be changed after replacement, and the replacement is meaningless, so you need to reselect two inserts. Only when the two selected inserts do not belong to the same type of inserts, they are replaced;

[0018] Enter S5 from S4, that is, the outer contour of the key can be determined according to the unlocking channel after the plug is replaced in S4; when entering S6 from S5, you can choose to repeat step S4 or proceed to step S7; if you repeat step S4, you can reselect two new sets of plugs to continue to replace, so as to achieve the exchange of the position of any plug, increase the types of unlocking channels of the plug lock that can be produced by the present invention, increase the diversity of the plug lock, and avoid the situation of common keys; if you proceed to step S7 (or finally proceed to step S7), install the plug and the reset spring in the plug slot, and finally complete the installation of the plug lock cylinder. In this way, the contour of the key used for unlocking can be determined during the installation of the plug lock cylinder, reducing the difficulty of key design; according to different needs, plug locks with different unlocking channels are produced to meet the growing market demand, avoid common keys, and improve anti-theft performance.

[0019] The beneficial effects of the present invention are as follows: a method for changing the unlocking channel of a plug-in lock is provided, by adjusting the sorting method of the processed plug-ins, that is, arranging and combining the plug-ins manually or by computer, so as to determine the contours of different unlocking channels. When the contour of the unlocking channel is determined, the contour of the key can also be determined. After the contour is determined, the key matching it is processed, thereby greatly reducing the amount of calculation and design. Moreover, as the number of plug-ins increases, the number of ways to arrange and combine the plug-ins increases, thereby combining more diverse channel contours to avoid the situation where keys are universal, thereby improving the anti-theft effect.

Figure 5 The flowchart of the method for changing the unlocking channel of the blade lock of the present invention is shown in FIG. The method for changing the unlocking channel of the blade lock of the present invention may include the following two embodiments: Example 1

[0028] A method for changing a blade lock unlocking channel, characterized in that it comprises the following steps:

[0029] S1: a lock core 1 is manufactured, a lock hole 11 is manufactured at one end of the lock core 1, and a plurality of insert slots 12 of the same specification and connected to the lock hole 11 are sequentially provided on the outer circumference of the lock core 1 in a direction away from the lock hole 11; a plurality of return springs 3 that can be installed in the insert slots 12 are manufactured; a plurality of groups of inserts 2 with the same outer contour and installable in the insert slots 12 are manufactured, the inserts 2 are provided with through slots 21, and the inserts 2 are divided into a plurality of categories according to the size and position of the through slots 21; a plurality of numbers of each category of inserts 2 are provided, and the number of the insert slots 12 is the same as the number of the inserts 2; in this embodiment, the total number of the inserts 2 is six, that is, n is 6;

[0030] S2: Each plug 2 corresponds to each plug slot 12 that is adapted to it and is arranged in order. Each plug slot 12 is set to be the first plug slot 12a, the second plug slot 12b, and so on in sequence in the direction away from the keyhole 11 until the sixth plug slot 12f. Initially, the plugs 2 corresponding to each plug slot 12 are set to be the first plug slot 2a, the second plug slot 2b, and so on until the sixth plug slot 2f.

[0031] S3: proceed to step S4;

[0032] S4: reselect or re-enter parameter x and parameter y, requiring 1≤x≤6, 1≤y≤6, x≠y; then, select the x-numbered plug 2 and the y-numbered plug 2 in a direction away from the keyhole 11; if the two plugs 2 do not belong to the same type of plugs 2, exchange the positions of the two selected plugs 2; if the two plugs 2 belong to the same type of plugs 2, reselect or re-enter parameter x or parameter y;

[0033] S5: When the positions of the insert pieces 2 and the insert slots 12 are made to correspond and the projections of the outer contours of the insert pieces 2 on the same plane overlap, the through grooves 21 of the insert pieces 2 form an unlocking channel, and the adapted key contour is determined according to the unlocking channel;

[0034] S6: proceed to step S7;

[0035] S7: Install the insert 2 and the return spring 3 into the insert slot 12.

[0036] For the insert lock in this embodiment, the number of inserts 2 is six, and accordingly, the insert slots 12 have the same specifications and the number is also six, and the outer contours of the six inserts 2 are designed to be of uniform specifications; in S2, the insert slots 12 and the inserts 2 are numbered, and are respectively set as the first insert slot 12a, the second insert slot 12b, the third insert slot 12c, the fourth insert slot 12d, the fifth insert slot 12e, and the sixth insert slot 12f, and the corresponding inserts 2 in each insert slot 12 are sequentially set as the first insert slot 2a, the second insert slot 2b, the third insert slot 2c, the fourth insert slot 2d, the fifth insert slot 2e, and the sixth insert slot 2f;

[0037] In this embodiment, when entering S3, step S4 is selected (of course, when entering S3, step S5 can also be selected to not replace the order of inserts 2, and the key profile is determined according to the initial state of inserts 2), and parameters x and y are input manually or in a computer program (the program that accepts user input parameters is an existing common program); the parameters x and y are required to be different and within the range of possible values, that is, the parameters x and y are both less than the total number of inserts 2, and the worker or the computer determines the position of the insert 2 to be replaced through the parameters x and y; if the two selected inserts 2 belong to the same type of inserts 2, that is, the size and opening position of the through slot 21 are the same, the unlocking channel profile will not be changed after replacement, and the replacement is meaningless, so the worker needs to re-select two inserts 2, and the computer program needs to re-receive new parameters; only when the two selected inserts 2 do not belong to the same type of inserts 2, they are replaced, and this judgment process is implemented by the operator or the computer program (it can be implemented by existing common programs such as logic judgment programs);

[0038] Entering S5 from S4, that is, according to the unlocking channel after replacing the insert 2 in S4, the outer contour of the key can be determined, reducing the difficulty of key design; when entering S6 from S5, choose to proceed to step S7, and install the insert 2 and the return spring 3 in the insert slot 12 by workers or by machines such as manipulators, and finally complete the installation of the insert lock cylinder 1.
