[0032] Please refer to Figure 6As shown, in the embodiment, the mechanical keyhole 140 is a non-cylindrical hole which is approximately a cylindrical hole, the non-cylindrical hole is formed by slightly expanding or contracting the cylindrical hole, the mechanical key 300 comprises a cylinder 301 matched with the non-cylindrical hole and a knob 302 for twisting. The mechanical keyhole 140 adopting a non-cylindrical hole which is approximately a cylindrical hole can play a good anti-theft effect, for the standard cylinder which can be inserted into the mechanical keyhole 140, it is unable to drive the mechanical keyhole 140 to rotate, that is, it is unable to achieve unlocking; and other cylinders with shape difference are difficult to be inserted into the mechanical keyhole 140. In the application, the mechanical keyhole 140 is a non-cylindrical hole which is approximately a cylindrical hole, and the non-cylindrical hole is slightly expanded or contracted, and is connected smoothly, so it is difficult to find that it is a non-cylindrical hole without careful observation, and since the expansion or contraction amplitude is relatively slight, it is difficult to copy without precise manufacturing, thus playing a good anti-theft effect. In an embodiment, the cross section of the mechanical keyhole 140 is shown in FIG. 2, wherein the solid line shown is a standard circle, the mechanical keyhole 140 is configured to be partially convex as shown by the dotted line, that is, the cross section shape of the mechanical keyhole 140 is composed of the left half of the solid line and the right half of the dotted line. Figure 7 As shown in FIG. 2, the cross section of the mechanical keyhole 140 is shown, wherein the solid line shown is a standard circle, the mechanical keyhole 140 is configured to be partially convex as shown by the dotted line, that is, the cross section shape of the mechanical keyhole 140 is composed of the left half of the solid line and the right half of the dotted line.
[0033] As shown in FIG. 2, the cross section of the mechanical keyhole 140 is shown, wherein the solid line shown is a standard circle, the mechanical keyhole 140 is configured to be partially convex as shown by the dotted line, that is, the cross section shape of the mechanical keyhole 140 is composed of the left half of the solid line and the right half of the dotted line. Figure 5 Figure 6 Figure 8 As shown in FIG. 2, the cross section of the mechanical keyhole 140 is shown, wherein the solid line shown is a standard circle, the mechanical keyhole 140 is configured to be partially convex as shown by the dotted line, that is, the cross section shape of the mechanical keyhole 140 is composed of the left half of the solid line and the right half of the dotted line.
[0034] When in use, when the mechanical key 300 is not inserted into the mechanical keyhole 140, the sliding block 18 is in a falling position under the action of gravity. At this time, the circumferential connecting part at the lower end of the sliding block 18 is connected to the output shaft 11, and the circumferential connecting part at the upper end of the sliding block 18 is connected to the worm gear 17. When the electronic key 200 is inserted, the electronic key 200 supplies power to the motor 15 and provides an unlocking signal. The motor 15 works to drive the worm gear 17 to rotate through the worm 16. The worm gear 17 drives the sliding block 18 to rotate synchronously. The sliding block 18 drives the output shaft 11 to rotate synchronously. The output shaft 11 drives the lock tongue 2 to rotate synchronously, so as to realize unlocking or locking.
[0035] When the electric unlocking component malfunctions, the mechanical key 300 can be used to unlock or lock. The mechanical key 300 is inserted into the mechanical keyhole 140, and the magnet 303 in the mechanical key 300 attracts the sliding block 18 upward. At this time, the circumferential connecting part at the upper end of the sliding block 18 is disengaged from the worm gear 17 and circumferentially connected to the connecting sleeve 14. Instead, the clearance groove of the sliding block 18 is located at the worm gear 17. At this time, rotating the mechanical key 300 drives the connecting sleeve 14 to rotate, and the connecting sleeve 14 drives the sliding block 18 to rotate synchronously. The sliding block 18 drives the output shaft 11 to rotate synchronously, and the output shaft 11 drives the lock tongue 2 to rotate synchronously, so as to unlock or lock.
[0036] When someone needs to unlock the manhole cover, the locking element 12 can be manually loosened or removed. This causes the locking tongue 2 and the output shaft 11 to become out of sync in the circumferential direction. At this time, the locking tongue 2 can be manually rotated to unlock the manhole. The rotation of the locking tongue 2 will not cause the output shaft 11 to rotate synchronously, that is, it will not exert force on the output shaft 11. Consequently, it will not act on the motor 15 through the output shaft 11, worm gear 17, and worm 16. It will not be obstructed by the electric unlocking component, and at the same time, it will not cause the electric unlocking component to be damaged under external force.
[0037] As described above in the specific embodiments, the intelligent manhole cover lock device 100 provided by this utility model has a locking member 12 on the back of the lock body 1 for locking the latch 2 to the output shaft 11. The locking member 12 can be operated on the back of the lock body 1 to release the lock between the latch 2 and the output shaft 11, allowing the latch 2 to unlock from the back of the lock body 1. The intelligent manhole cover lock device 100 provided by this utility model can unlock underground, increasing safety during use.
[0038] The utility model discloses, through several concrete embodiment is explained, and the technical personnel of the field should understand that, without departing from the range of the utility model, still can carry out various transformation and equivalent replacement to the utility model. In addition, aiming at specific situation or concrete case, can make various modifications to the utility model, and do not depart from the range of the use new. Therefore, the utility model is not limited to the specific embodiment disclosed, and should include all the implementation modes falling within the scope of the utility model claims.
