Description
Technical field
The utility model belongs to sewer and underground pipeline ancillary facility.
Background technology
In recent years, the traffic accident that causes owing to the sewer well lid is stolen, hurted sb.'s feelings and the destruction of facility in the well was happened occasionally, caused heavy losses, so various anti-stealing manhole cover arises at the historic moment.Roughly be divided into four classes: 1, on well lid, add lockset; with key operated; though solved the stolen problem of well lid; but the cost height, complex operation, lockset corrosion, well lid are difficult to open; 2, with connector well lid and well head are combined as a whole; this mode can not effectively be protected facility in the well, because well lid can not be taken fully, brings inconvenience to construction.3, adopt frame for movement to block well lid, use special tool to open, shortcoming is a complicated in mechanical structure; open and close loaded down with trivial detailsly, be easy to replace with other instruments, safety is poor; 4, adopt the material do not have recovery value, make useless that it steals, but can not protect facility in the well.
Summary of the invention
In order to overcome existing anti-stealing manhole cover lockset and connector complex structure; cost height, loaded down with trivial details, the poor safety performance of keying; can not effectively protect deficiencies such as the interior facility of well; the utility model provides a kind of anti-stealing manhole cover; this anti-stealing manhole cover is not only simple in structure; theftproof performance is good, and opens and closes simple and easy to do safe and reliable.
The technical scheme that the utility model technical solution problem is adopted is: the anti-stealing manhole cover back side is provided with the keyhole support, the well lid bolt places the keyhole support, establish the keying hole along well lid center line lateral symmetry, on the well lid bolt, establish with well lid and open and close corresponding claw hole, hole, alignment pin is established in keyhole support both sides, well lid bolt rear portion, well lid bolt rear portion is positioned at well lid outer downside and establishes fixed card slot, and claw is established in the key lower end that opens and closes well lid, and claw is
The shape structure, with the movable pin joint of spoon bar under shed groove portion, sleeve places a spoon bar middle and lower part, and open in its left side, lower end, outer
The shape groove, oblong aperture is opened on the right side.
During installation, well lid one side fixed card slot is blocked edge in the well head, the pulling sleeve is stretching with key, claw inserts well lid and opens and closes the hole, promotes sleeve, makes claw horizontal, claw hooks well lid bolt upper clipping claw hole, and key lever, claw are stirred the well lid bolt and advanced, block the well, can lock firm well lid, during unlatching, insert key and promote sleeve, claw is horizontal, hooks well lid bolt upper clipping claw hole, backward rotation lever, claw are stirred the well lid bolt and are retreated, and can open well lid.
The beneficial effects of the utility model are that well lid, well lid bolt, several part-structures of key are simple, and cost of production is low, and conveniently opening and closing is flexible, locks firm, safe and reliable.
