In this inspection shaft lid, described lockset is a magnetic lock.
In this inspection shaft lid, described magnetic lock is provided with the traveller of magnetic perpendicular to lid in magnetic lock, traveller be provided with dovetail groove in appearance, the other end of described cover plate is provided with the plush copper that can be inserted in this dovetail groove, the shape of plush copper also is a dovetail shaped; Be provided with end magnetic patch in the inboard of traveller, two ends polarity mutually close between end magnetic patch and the traveller is identical.
In this inspection shaft lid, the end of described plush copper is tapered.
In this inspection shaft lid, the position in described magnetic lock on the surface of lid is provided with pit.
In this inspection shaft lid, the hinged end of described cover plate is formed with slotted hole, and the steady pin that is connected on the lid passes in the described slotted hole.
Compared with prior art, the beneficial effects of the utility model are:
One side and the well head of inspection shaft lid are hinged, and a relative side can be connected to the corresponding position of well head by shackle member, and the inspection shaft lid is difficult to be dug, and it can be sealed on the well head very securely.And set cover plate has guaranteed that also shackle member can not be opened easily by unrelated person on lid, and this anti-stealing manhole cover good anti-theft effect has guaranteed the safety of road, can not increase the maintenance cost of municipal unit.
Description of drawings
Fig. 1 is the front view of this anti-stealing manhole cover.
Fig. 2 is the structural representation of this anti-stealing manhole cover, not shown cover plate.
Fig. 3 is along the A-A sectional view among Fig. 2.
Fig. 4 is the lateral view of this anti-stealing manhole cover cover plate.
The specific embodiment
See in the accompanying drawing that this anti-stealing manhole cover mainly comprises the tabular lid 1 of a circle, be provided with the articulated section at a side of lid 1, the hinged seat 5 of this articulated section for being connected as a single entity with lid 1, hinged seat 5 is used to be hinged on the inspection shaft mouth.
Dorsal part at lid 1 is provided with a rotating shackle member 2, and it is positioned at a side relative with the articulated section on the lid.Shackle member be one L shaped, comprise the rotary column 7 that passes lid 1 above it, rotary column 7 generally is a prism.Have a depression assembly section in the front of lid 1, the end of rotary column 7 extend in this assembly section.Be equipped with a cover plate 3 in the assembly section, an end of cover plate 3 is hinged on the lid 1 by the steady pin 6 that is fixed on the lid 1, and the other end is connected with lockset on being located at lid 1 dorsal part.The end that cover plate 3 is connected with steady pin 6 forms a slotted hole 11 by the mode of bending, and described steady pin 6 passes slotted hole 11.
Above-mentioned lockset is a magnetic lock, and its structure comprises the stationary magazine creel 13 that is vertically fixed on lid 1 dorsal part, and it is generally made by non-magnet materials such as copper, aluminium alloys or alloy plastics.Magnet 8 at the bottom of the bottom of stationary magazine creel 13 was fixed with one, and were provided with traveller 9 with gap in the outside of end magnet 8 in the stationary magazine creel 13, and traveller 9 can slide in stationary magazine creel 13.Traveller 9 has magnetic, it with end magnetic patch 8 between the polarity at mutually close two ends identical, like this end magnetic patch 8 just can promote traveller 9 in stationary magazine creel 13 towards the motion of the direction of cover plate 1, certainly to the magnetic force that produces between them should greater than frictional force between the gravity of traveller 9 and traveller and the stationary magazine creel and.Magnetic patch of the described end 8 also can be replaced by the compression spring, considers that inspection shaft covers residing environment, is preferably the end magnetic patch 8 that has magnetic.
On the lateral surface of traveller 9, be provided with dovetail groove 10, this dovetail groove 10 is along the axial direction setting of traveller 9, and the other end of above-mentioned cover plate 3 is bending, this end extend into the dorsal part of lid 1, and its end has a plush copper 12, plush copper 12 is a symmetrical structure, and it and dovetail groove 10 structures match, and plush copper 12 can be inserted in the dovetail groove 10.It is convenient to peg graft when guaranteeing that plush copper 12 is inserted in the dovetail groove 10, and the end of plush copper 12 is tapered.
Traveller 9 and stationary magazine creel 13 can be columniform, at this moment, can on the inwall of stationary magazine creel 13, be axially arranged with the guiding convex body, and on the outer peripheral face of traveller 9, be axially arranged with groove with guiding convex body matched in clearance, like this, traveller 9 can slide up and down in stationary magazine creel, and can not take place by a relatively large margin relative to circumferentially rotating.Certainly, traveller 9 and stationary magazine creel 13 also can be the prisms that cooperatively interacts.
This anti-stealing manhole cover is when normal the use, and the other end of cover plate 3 is lockable, and cover plate 3 covers in the rotary column 7 on the described shackle member 2.At this moment, the plush copper 12 on the other end of cover plate 3 is inserted in the above-mentioned dovetail groove 10, and under the magneticaction of end magnetic patch 8, the dovetail groove 10 on the traveller 9 is close on the plush copper 12, realizes fixedly clamping between plush copper 12 and the dovetail groove 10.Be provided with a pit 4 in the position of above-mentioned magnetic lock in cover plate 3 fronts, can utilize magnetic key to insert in this pit 4, polarity on the magnetic key should guarantee that it can make above-mentioned traveller 9 towards moving away from the position of lid 1, and the size of magnetic force also has certain requirement on the magnetic key, when it should be able to guarantee in being inserted into pit 4, dovetail groove 10 present positions on the traveller 9 can conveniently be extracted the plush copper 12 on the cover plate 3 in dovetail groove 10.And the slotted hole 11 on the cover plate 3 can slide on steady pin 6, thereby makes cover plate 3 releases, so just can rotate shackle member 2 by rotary column 7, and then can open the inspection shaft lid.When realizing that the inspection shaft lid is opened, if the suffered magnetic force of traveller 9 is excessive, then the upper part of dovetail groove 10 can be close on the plush copper 12 on the traveller 9, be firm clamping connection between the two.Therefore, when having only active force between the above-mentioned parts that have magnetic to reach a balance, could realize the release of cover plate 3, this just needs special-purpose key could realize unlatching.It is little that magnetic lock is subjected to the influence of external environment, and it can be used in the inspection shaft that exposes in the external world easily and cover.
