Wherein shown in figure one, figure two and the figure three: the middle part in the lid 1 is equipped with and is driven bull stick 10 and dustproof bull stick 11, drive bull stick one end reed 17 is housed successively, moving block 6 and elastic washer and nut, locking bar 7 all is equipped with at the moving block two ends, is with locking bar verge ring 8 on the locking bar.Dust cap 13 and dustproof bull stick 11 1 end riveteds, its other end are equipped with spiral garden cylindrical spring 16 and plain washer, nut successively.

Shown in figure four, figure five and the figure six: place garden female cap 1 on the base 2, a pedestal 9 is installed in middle part, the lid back side, is equipped with by pedestal and well lid and drives bull stick 10 and starting bar 12, and an end that drives bull stick is equipped with moving block 6 and packing ring and nut successively.3 locking bars 7 of edge assembling of moving block, an end of starting bar is equipped with torsion spring 14 successively, crank 4 and packing ring and nut.The other end of crank with start hammerlock 5 in long through groove link to each other with the form of being slidingly matched, be with locking bar verge ring 8 on the locking bar, dust cap 13 and dustproof bull stick 11 riveteds, the other end of the bull stick that prevents dust is equipped with nut garden cylindrical spring 16 and plain washer and nut successively.

Describe concrete structure of the present utility model and working condition in detail below in conjunction with accompanying drawing:

Embodiment 1: a kind of rectangle well lid, see shown in figure one, figure two and the figure three that wherein figure three lid both sides boss are the contact surfaces that are placed on cement, ash, the husky base that mixes the system of giving, and its catch means is in locked state.When need are opened lock, 13 groups of dust caps are changeed certain angle, key is inserted in driving bull stick 10 ends that the cross section is an equilateral triangle (also can be made into other regular polygon), rotation along with key, driving the moving block 6 that assembles on the bull stick rotates together, the moving block two ends are by the withdrawal relatively simultaneously of bolted locking bar 7, make the external part of locking bar break away from lockhole under the manhole cover base, this lockhole is to be drilled with blind hole or directly to make blind hole when cement base gives system on the cement well lid seat inner rim with on the relevant position, locking bar termination by Churn drill, so far, finish the whole process of unblanking, the rectangle well lid can be mentioned then.When the need lock uint cuts out, lid is placed on the base, with having section is that the key of the blind hole of positive triangle is inserted in and drives bull stick 10 ends, along with the rotation of key, drive bull stick and drive moving block 6 rotations, locking bar 7 relative elongations simultaneously of moving block two ends, its locking bar stretches out the termination and inserts in the lockhole under the base, promptly finish the process of locking, transfer to key again, dial back dust cap 13.Wherein driving the reed 17 that is with on the bull stick 10 is that half garden shape close proximity is touched with half garden form and moving block 6 bottom transverse sections, so that lid 1 is when being subjected to vibrating or when prizing, locking bar 7 is difficult for withdrawing from lockhole, 8 locking bar orientations of the locking bar verge ring on the locking bar.Dustproof the building in well lid front prevents that dust from entering the effect of open keyhole, and the spiral garden cylindrical spring 16 that is with on the dustproof bull stick 11 is to make dust cap be subjected to vibrating the back to be difficult for breaking away from original position.

Embodiment 2: a kind of garden female cap 1 and garden shape base 2 are shaped by cast iron, see figure four, shown in figure five and the figure six, when need lid 1 is mentioned when unblanking, push dust cap earlier aside, two keys that have square blind hole and positive triangle blind hole are enclosed within driving bull stick 10 ends and starting bar 12 ends respectively, rotate the key that has positive triangle blind hole earlier, along with driving cranks 4, the rotation starting bar 12 of key turns an angle, making startup hammerlock 5 is that the center rotates to an angle with hammerlock locating shaft 3, the protuberance that starts on the hammerlock breaks away from moving block 6 edge upper recess, rotate the key that has the square blind hole this moment again, rotation along with key, driving bull stick 10 drive moving blocks 6 rotates to an angle, make 3 locking bars (but also several locking bars) withdrawal simultaneously, break away from the recess under the base 2, extract key again, can mention well lid.When the well lid locking, make locking bar 7 withdrawals with manual (at the lid back side) or key startup, well lid is placed on the manhole cover base 2, insert the termination that drives bull stick 10 with the key that has the square blind hole again, along with rotating drive bull stick drive moving block 6 rotations of key, to inserting in the groove at moving block 6 edges to the boss that starts on the hammerlock, this hour locking lever has been stretched to base 2 times, extract key again, dial back dust cap 13, promptly finish the whole process of locking.Wherein 14 1 of the torsion springs that is with on the starting bar 12 are stuck on the hammerlock locating shaft 3, and the other end is stuck on the crank 4, and its effect is a well lid when being vibrated or when prizing, and crank 4 is difficult for rotating.Here the key of different well lids, the one end is the blind hole that has regular polygon, the other end can make little platypelloid type or T-shape, the former effect is to dial dust cap 13 or choose earth in the open keyhole, the latter can insert garden shape well lid, carry covering in the slotted hole 15 and can carry lid, whole key shape can make " " " or by two form "T"-shaped.In addition, the lead to the hole site of driving bull stick 10 and starting bar 12 can be avoided " feedwater ", " sewage " or the signs such as " rainwater " on the well lid front on the shape well lid of garden, and new well lid does one to mobile with its sign when casting.
