[0038] Reference Figure 1-6 , an embodiment of the present utility model shows a decentralized management step ten-thousand-turn operator, including a lock base 1, a lock core 2, at least one bolt 3 and at least one unlocker 4;
[0039] Reference Figure 2 , a channel 11 is provided in the lock base 1, and a plurality of protrusions 12 arranged at intervals in the circumferential direction are convexly provided on the inner wall of the channel 11. A card slot 13 is formed between two adjacent protrusions 12. The shaft section position of the channel 11 where the protrusions 12 are provided is defined as the first shaft section 11a, and the shaft section with a certain length adjacent to the first shaft section 11a in the channel 11 is defined as the second shaft section 11b;
[0040] Reference Figure 2, the lock core 2 is arranged in the channel 11. A plurality of lock pins 21 arranged axially are provided on the lock core 2. At least one lock pin 21 is located in the first shaft section 11a, and at least one lock pin 21 is located in the second shaft section 11b. In the natural state, the lock pins 21 protrude from the lock core 2 and are inserted into the card slots 13.
[0041] Reference Figure 4 and Figure 5 , the bolt 3 is detachably arranged in the card slot 13. At least part of the bolt 3 extends into the second shaft section 11b, and the part of the bolt 3 located in the second shaft section 11b circumferentially blocks at least one lock pin 21 located in the second shaft section 11b.
[0042] The unlocker 4 is used to drive at least all the lock pins 21 located in the first shaft section 11a to retract into the lock core 2.
[0043] Specifically, the unlocker 4 is a key. A keyhole for inserting the key is provided at one end of the lock core 2, and an angular encoder is connected to the other end. Wherein, a spring (not shown) for ejecting the lock pin 21 is provided in the lock core 2. After the key is inserted, the key can resist the elastic force of the spring and retract the lock pin 21 into the lock core 2, so that the lock pin 21 does not restrict the rotation of the lock core 2. Different rotation angles of the lock core 2 will trigger the angular encoder to output different signals, thereby enabling the device to perform different actions. Wherein, the specific structures and working principles of the lock core 2 and the key can refer to the prior art. In addition, in this embodiment, a plurality of bolts 3 can be provided, and the lengths of the plurality of bolts 3 extending into the second shaft section 11b are different. A plurality of unlockers 4 can be provided, and the number of lock pins 21 retracted into the lock core 2 driven by the plurality of unlockers 4 is different.
[0044] The working principle will be introduced through a specific example below:
[0045] As Figure 6 shown, Figure 6 The structure shown can be imagined as the structure after the first shaft section 11a and the second shaft section 11b in the channel 11 are cut open from the side and laid flat. Bolts 3 of different lengths are respectively inserted into two of the card slots 13. For the convenience of description, the shorter bolt 3 will be hereinafter referred to as the short bolt 3a, and the longer bolt 3 will be referred to as the long bolt 3b. Five lock pins 21 are provided on the lock core 2, three of which are located in the first shaft section 11a, and the other two are located in the second shaft section 11b. For the convenience of description, the five lock pins 21 are sequentially called the first lock pin 21, the second lock pin 21, the third lock pin 21, the fourth lock pin 21, and the fifth lock pin 21 from bottom to top. In application, the unlocker 4 can be divided into three types, namely the low-authority unlocker 4, the medium-authority unlocker 4, and the high-authority unlocker 4.
[0046] Among them, the low-authority unlocker 4 can retract the first to third locking pins 21 into the lock core 2. When the low-authority unlocker 4 is inserted, the first to third locking pins 21 retract into the lock core 2, while the fourth locking pin 21 and the fifth locking pin 21 still protrude from the lock core 2. At this time, the lock core 2 can be rotated. However, since the short pin 3a blocks the rotation path of the fourth locking pin 21, the rotation range of the lock core 2 is from the initial position to between the short pin 3a; among them, by changing the position of the card slot 13 into which the short pin 3a is inserted, the rotation range of the lock core 2 can be changed, which is equivalent to changing the operation authority of the low-authority unlocker 4.
[0047] The medium-authority unlocker 4 can retract the first to fourth locking pins 21 into the lock core 2. When the medium-authority unlocker 4 is inserted, the first to fourth locking pins 21 retract into the lock core 2, while the fifth locking pin 21 still protrudes from the lock core 2. The long pin 3b blocks the rotation path of the fifth locking pin 21. The rotation range of the lock core 2 is from the initial position to between the long pin 3b. Obviously, the medium-authority unlocker 4 makes the rotation range of the lock core 2 larger than that of the low-authority unlocker 4, that is, the operation authority of the medium-authority unlocker 4 is greater than that of the low-authority unlocker 4; similarly, by changing the insertion position of the long pin 3b, the operation authority of the medium-authority unlocker 4 can be changed;
[0048] The high-authority unlocker 4 can retract all the first to fifth locking pins 21 into the lock core 2, so that the lock core 2 can rotate freely without being blocked by the convex block 12 and the pin 3; it is equivalent to being able to use the lock core 2 to output any signal of the angular encoder, that is, any operation on the device can be realized.
[0049] It should be noted that the number of locking pins 21 on the lock core 2 may not be five, and the pin 3 may block more than one locking pin 21 in the second shaft section 11b; the number of pins 3 can be more, and at the same time, the unlocker 4 can also be divided into more different authority levels, not just the three levels of low, medium, and high.
[0050] In some embodiments, as Figure 4 shown, the card slot 13 is a dovetail groove structure. The pin 3 is slidably connected to the card slot 13 in the axial direction, and the part of the pin 3 inserted into the card slot 13 matches the dovetail groove structure. In this way, the pin 3 cannot leave the card slot 13 in the radial direction, ensuring the stable position of the pin 3 in the card slot 13.
[0051] In some embodiments, referring to Figure 2 and Figure 5, the bolt 3 includes a bolt body slidably connected to the slot 13. On both sides of the part of the bolt body located within the second shaft section 11b along the circumferential direction of the channel 11, there are support portions that abut against the ends of the bumps 12; specifically, as Figure 5 shown, by providing lateral support to the bolt body located within the second shaft section 11b through the support portions, it can be avoided that when the locking pin 21 of the lock core 2 collides with the bolt 3, the bolt 3 is prone to breakage;
[0052] In addition, on both sides of the part of the bolt body located within the second shaft section 11b along the circumferential direction of the channel 11, support portions can be provided to form a structure similar to a T-shape, and similarly, it can be avoided that the bolt 3 is prone to breakage.
[0053] In some embodiments, the widths of the multiple bumps 12 are the same, and the widths of the multiple slots 13 are the same. In this way, it is convenient to regularly adjust the rotation angle of the lock core 2; for example, one bump 12 can be set to 5°, and one slot 13 can be set to 5°. When the bolt 3 is adjusted backward (based on the rotation direction of the lock core 2) by the position of one slot 13, it is equivalent to increasing the rotation angle of the lock core 2 by 10°. Taking Figure 6 as an example, assuming that the short bolt 3a in the figure is inserted into a slot 13 at the back, the rotation angle of the lock core 2 rotated by the low-authority unlocker 4 changes from 25° to 35°.
[0054] In some embodiments, as Figure 2 and Figure 3 shown, the lock base 1 includes a mounting base 14, a lock shell 15, and an end cap 16. An installation cavity 141 is provided in the mounting base 14. The lock shell 15 is disposed within the installation cavity 141 and is circumferentially relatively fixed to the mounting base 14. The end cap 16 is detachably disposed at the opening of the mounting base 14. The mounting base 14, the lock shell 15, and the end cap 16 together form the channel 11; the first shaft section 11a and the second shaft section 11b are formed within the lock shell 15, and the lock core 2 is disposed within the lock shell 15. Specifically, the mounting base 14 and the end cap 16 are threadedly connected. To achieve the circumferential relative fixation of the mounting base 14 and the lock shell 15, at least one positioning groove 142 is recessed on the inner wall of the installation cavity 141, and a positioning block 151 for engaging with the positioning groove 142 is protruded on the outer wall of the lock shell 15. In this embodiment, by removing the end cap 16, the lock shell 15 can be taken out to adjust the number or position of the bolts 3, etc., and it is also convenient for maintenance and other operations.
[0055] In summary, the embodiment of the present invention provides a decentralized management stepped ten-thousand-turn operator, and the beneficial effects of this decentralized management stepped ten-thousand-turn operator are as follows:
[0056] 1. High security: The convex block 12 is used to block the lock pin 21 on the first shaft section 11a of the lock core 2. When the lock core 2 is not unlocked by the unlocker 4, the lock core 2 cannot be rotated, ensuring that unauthorized personnel cannot operate the decentralized management step multi-turn operator and ensuring the safety of the device.
[0057] 2. Decentralized operation function: The bolt 3 is inserted into the card slot 13, so that the bolt 3 can block the lock pin 21 on the second shaft section 11b. Bolts 3 of different lengths block different numbers of lock pins 21 within the second shaft section 11b. The unlocker 4 can be divided into multiple unlocking authorities according to the number of lock pins 21 it can retract. It is necessary to use the unlocker 4 to retract the lock pin 21 within the second shaft section 11b to correspondingly avoid the blockage of the bolt 3. That is, different unlockers 4 can rotate the lock core 2 by different angles, and the corresponding operation functions are realized through different rotation angles of the lock core 2.
[0058] 3. Structural flexibility: The bolt 3 is detachably arranged in the card slot 13, and the bolt 3 can be arranged in the card slots 13 at different positions according to actual needs, so as to adjust the rotation angle of the lock core 2 after being unlocked by the unlocker 4.
[0059] In the above embodiments, the descriptions of each embodiment have their own emphases. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
[0060] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
