The technical problem that the utility model solved adopts following technical scheme to realize:
A kind of pattern manhole cover lock buckle structure; Comprise well seat, well lid, lockset and lockaid gun, said well lid links to each other with said well seat, and said lockset is located at the bottom surface of said well lid; Said lockset comprises a lock chamber; On said lock chamber, extending has a dead bolt, and said dead bolt passes the lower edge that the holder that is fixedly arranged on the said well lid bottom surface extends to said well seat, also is equipped with a spring on the said dead bolt; On said well lid, also offer an open keyhole, the working end of said lockaid gun is passed said open keyhole and is contacted with said lock chamber.
Said lockaid gun comprises a locking bar, and an end of said locking bar is provided with the leader, and the other end of said locking bar is provided with a tapered end, on said locking bar, also is provided with locating piece, and said locating piece is between said handle and said tapered end.
On the upper surface of said well lid, also be provided with locating groove, said locating groove and said locating piece are complementary.
Said tapered end and said lockhole are complementary, and said tapered end can rotate 180 degree at least along the inwall of said lock chamber.
On said dead bolt, also be arranged with a spring limited block, said spring limited block is placed on the annular slot on the said dead bolt, and said spring limited block is between two said fixed blocks, and said spring places between said spring limited block and the said fixed block.
As required, more than one said lockset is set on said well lid.
The beneficial effect of the utility model is simple in structure, and is easy to use, has reliable anti-theft feature.

The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Shown in Fig. 1-6, a kind of pattern manhole cover lock buckle structure comprises well seat 2, well lid 1, lockset 4 and lockaid gun 3; Well lid 1 links to each other with well seat 2; Lockset 4 is located at the bottom surface of well lid 1, and lockset 4 comprises a lock chamber 42, and on lock chamber 42, extending has a dead bolt 41; Dead bolt 41 passes the lower edge that the fixed block 44 that is fixedly arranged on well lid 1 bottom surface extends to well seat 2; Also be equipped with a spring 43 on the dead bolt 41, on well lid 1, also offer an open keyhole 11, the working end of lockaid gun 3 is passed open keyhole 11 and is contacted with the inside of lock chamber 42.
On the upper surface of well lid 1, also be provided with locating groove 12, locating groove 12 is complementary with locating piece 33.
Tapered end 33 is complementary with lockhole 11, and tapered end 33 can rotate 180 degree at least along the inwall of lock chamber 42.
On dead bolt 41, also be arranged with a spring limited block 45, spring limited block 45 is placed on the annular slot 46 on the dead bolt, and spring limited block 45 is between two fixed blocks 44, and spring 43 places between spring limited block 45 and the fixed block 44.
During use, in the lockhole 11 that inserts the tapered end of lockaid gun 3 33 on the well lids 1, this moment tapered end 33 with the inwall joint of lock chamber 42; Lockaid gun 3 Rotate 180s °, tapered end 33 drives lock chamber 42 and moves to introversion, makes the head of dead bolt 41 break away from the lower edge of well seat 2; At this moment, the lockset 4 of well lid 1 just is in opening, owing to be arranged with spring 43 on the dead bolt 41; During lockaid gun 3 rotations, spring 43 can be compressed, and presses lockaid gun 3 downwards; Make locating piece 32 card on the lockaid gun 3 as in the draw-in groove on the well lid 1 12, the lockset 4 of well lid 1 just can not be because of the restoring force of spring 43 be closed like this, and tapered end 33 can not take out in locking chamber 42; So upwards lift handle 31, well lid 1 just can take out in well seat 2.The reverse rotation lockaid gun 3 again, and dead bolt 41 stretches out forward under the restoring force effect of spring 43, make the head of dead bolt 41 be stuck in the lower edge of well seat 2 again, thereby reach anti-theft feature.
Can as required a plurality of locksets 4 can be set on well lid 1.
