The magnetic control part 131 comprises the bar magnet 1311 and the plug block 1312, and has the advantages that: 1. the plugging block 1312 is not a magnetic object and is made of a more durable material, so that the service life of the device is guaranteed; 2. the insertion block 1312 has a magnetic shielding function to prevent the bar magnet 1311 from affecting the return spring 141 described below; 3. the bar magnet 1311 has a stable magnetic region and is inexpensive. The design of the plugging groove increases the contact area between the bar magnet 1311 and the plugging block 1312, so that the bar magnet 1311 can stably push the plugging block 1312.

When the magnetic control key 3 corresponds to the same pole of the magnetic control switch 13, the bar magnet 1311 pushes the insertion block 1312 to compress the return spring 141 under the action of the repulsive force and simultaneously passes through the through hole 133 to be inserted into the magnetic hole 132, when the magnetic control key 3 is pulled out and the repulsive force of the bar magnet 1311 disappears, the insertion block 1312 is separated from the magnetic hole 132 under the action of the elastic force of the return spring 141, and the linkage effect is cancelled; the return spring 141 for the return component 14 has the advantages of stable return spring 141, convenient spring coefficient selection, low cost and long service life.

The magnetic control key 3 is provided with a plurality of magnetic control portions 131 that are used for unblock lockhole 11 interior bar magnet 1311 including the handle portion 31 that supplies the user to hold and the key mobile jib 32 that is the setting of cylindric structure and being located between key mobile jib 32 and the handle portion 31 and being used for driving mechanical lock core 1 pivoted turning block 33, key mobile jib 32 is provided with a plurality of bar magnet 1311's that are used for unblock lockhole 11 along its length direction, mechanical lock core 1 rotates along with turning block 33 after magnetic control portion 131 and lockhole 11 interior magnetic control switch 13 one-to-one homopolar correspondence completion unblock operation, the one end that handle portion 31 was kept away from to key mobile jib 32 is provided with the magnetizer of bar magnet 1311 that resets, the magnetizer adsorbs the bar magnet 131.

The magnetic control key 3 is used for opening the mechanical lock cylinder 1, and the key main rod 32 with a cylindrical structure design plays the following roles: 1. the convenient user inserts in lockhole 11 through arbitrary angle, need not like the key in the prior art need aim at lockhole 11 and can insert to the efficiency of unblanking that improves has made things convenient for the operator to use greatly. 2. The cylindrical shape is convenient to rotate, and the resistance force is small compared with the existing key unlocking, so that the effect of facilitating the rotation of an operator is achieved.

Through the up-down position relation of the plurality of magnet parts 321 and the angle relation of the magnets in the magnet parts 321, various encryption conditions can be achieved, the manhole cover lock can be unlocked only when the magnet parts 321 correspond to each other from top to bottom one by one, (if the up-down space positions of the magnet parts 321 cannot correspond to each other, the repulsion force between the magnets in the magnet parts 321 and the magnets in the lock holes 11 is insufficient, and the manhole cover lock cannot be unlocked; if the angle positions cannot correspond to each other, the magnets in the magnet parts 321 and the magnets in the lock holes 11 cannot be correctly unlocked), in the plurality of magnet parts 321, the manhole cover lock cannot be rotated if one magnet part 321 cannot correspond to each other, so that the encryption degree of the key is high, and the condition that the manhole cover and the private manhole cover are stolen is avoided. The design of the magnet portion 321 is not easily counterfeited and cannot be copied by a conventional key shop, and the magnet portion 321 can be repeatedly manufactured again according to the data recorded in the computer even if the magnet portion 321 is lost.

This magnetizer's design, when with the well lid closed back, the key is in the extraction process, can attract with bar magnet 1311 in the lockhole 11 to make bar magnet 1311 in the lockhole 11 resume original position from supreme down one by one, make the well lid lock be in the locking state.

The linkage component 23 includes a clutch block 231 for linking and combining the rotating member 21 and the linkage member 22, a driving motor 232 for driving the clutch block 231 to perform linking or separating operation, and a transmission block 233 arranged between the driving motor 232 and the clutch block 231, the clutch block 231 and the transmission block 233 are rotatably connected, and the transmission block 233 is in threaded connection with a rotating shaft 2321 of the driving motor 232. Use driving motor 232 benefit at the transmission stable, be connected for rotating between separation and reunion piece 231 and the transmission piece 233, so rotating under the linkage state piece 21 rotates the in-process, separation and reunion piece 231 still can normally rotate, thereby reach and drive linkage piece 22 and rotate, and driving motor 232's pivot 2321 carries out threaded connection with transmission piece 233, rotate through driving motor 232 and make transmission piece 233 move along the direction of height of pivot 2321 also be length direction, thereby reach and drive separation and reunion piece 231 and carry out the effect of removing along the direction of height of pivot 2321, through the upper and lower position relation of separation and reunion piece 231, realize with linkage structure 24 whether linkage.

The transmission block 233 comprises a connecting portion 2331 for rotatably connecting the clutch block 231 and a moving portion 2332 in threaded connection with the rotating shaft 2321, and the height of the connecting portion 2331 is smaller than that of the moving portion 2332; the rotating member 21 is made compact in its inner structure.

The rotating shaft 2321 penetrates through the moving part 2332 in the height direction, a threaded through pipe 2333 wound around the outer side wall of the rotating shaft 2321 is arranged in the moving part 2332, the threaded through pipe 2333 is spirally extended in the length direction of the rotating shaft 2321, an extension rod 2322 which is abutted against the threaded through pipe 2333 and plays a role in guiding is arranged on the rotating shaft 2321, and the transmission block 233 moves in the height direction of the rotating shaft 2321 in the rotating process of the rotating shaft 2321. Due to the design of the threaded through pipe 2333 and the extension rod 2322, when the rotating shaft 2321 is driven to rotate by the driving motor 232, the extension rod 2322 rotates along the thread direction of the threaded through pipe 2333, so that the transmission block 233 moves along the height direction of the rotating shaft 2321 without rotating, thereby achieving the effect of driving the clutch block 231 to move.

The rotating member 21 includes an adaptor plate 211, the adaptor plate 211 is provided with an adaptor groove 241, the linkage member 22 is provided with a gear groove 242, the clutch block 231 includes a clutch portion 2311 engaged with the adaptor groove 241 and the gear groove 242 and a separating portion 2312 having a diameter length smaller than that of the clutch portion 2311, and the linkage member 22 rotates along with the rotation of the rotating member 21 when the clutch portion 2311 is engaged with the gear groove 242 and the adaptor groove 241, respectively. The switching piece 211 plays a role in starting and stopping, the rotating piece 21 rotates the switching piece 211 and also rotates, when the clutch block 231 is meshed with the switching groove 241 on the switching piece 211, the switching piece 211 rotates the clutch block 231 and also rotates, at the moment, if the clutch block 231 is also meshed with the gear groove 242, the clutch block 231 rotates the second gear and rotates along with the second gear, the linkage relation is one layer after another, and the stable transmission effect is achieved. When the separating portion 2312 is located at the interlocking position, since the radial length of the separating portion 2312 is smaller than the radial length of the clutch portion 2311, the separating portion 2312 cannot be engaged with the coupling groove 241 and the gear groove 242, and the rotor 21 is in an idling state.
