Safety and reliability.So, it is very necessary to design a kind of four sides locking secure communication well lid with anti-theft feature.
Utility model content：
In place of the utility model makes up and improves above-mentioned the deficiencies in the prior art, there is provided a kind of reasonable in design,
Safety well cover is locked at a kind of safe and reliable, easy for installation four sides for communication engineering with anti-theft feature, can be extensive
Ground is promoted and is used.
The technical solution adopted in the utility model is：Safety well cover is locked at a kind of four sides for communication engineering, including ring
Shape base and carbon fiber well lid, the center of carbon fiber well lid are provided with center sleeve, are welded with circumference uniform distribution four on center sleeve
Individual locking cross bar, locking crossbar end are provided with inclined-plane locking head；Annular base is provided with the locking device of four circumference uniform distributions, lock
Tight device includes plinth, inclined-plane telescopic head, spring and anti-theft screw, and inclined-plane telescopic head is located in the square hole of plinth,
Spring one end is welded with end cap with the welding of inclined-plane telescopic head, the other end, and the flexible overhead in inclined-plane is provided with stopper slot, anti-theft screw position
Above stopper slot, the upper lower cross plate of plinth is provided with symmetrical solution lock crossbeam and square groove, two of plinth
Side plate is provided with symmetrical chute.
Described inclined-plane telescopic head is consistent with the bevel angle of inclined-plane locking head, and chamfer length is also identical.
Described anti-theft screw is installed using special Anti-theft wrench and is dismantled.
The locking device of described annular base when mounted, is coordinated with carbon fiber well lid and installs.
The beneficial effects of the utility model：Reasonable in design, safe and reliable, easy for installation, with anti-theft feature, it is easy to
Promote on a large scale and use.First annular base is installed on well head, anti-theft screw is pulled down using Special anti-theft spanner, will
Four locking devices on the locking cross bar alignment annular base of carbon fiber well lid, then firmly carbon fiber well lid is pushed, pushing
When inclined-plane locking head inclined-plane and inclined-plane telescopic head contact of incline plane, and inclined-plane telescopic head is pushed into the square hole of plinth
Interior, when inclined-plane locking head is located at below inclined-plane telescopic head, inclined-plane telescopic head is displaced outwardly being placed in tiltedly under the action of the spring
The top of face locking head, inclined-plane locking head are plane contact with inclined-plane telescopic head, realize the purpose of carbon fiber well lid four sides locking,
Anti-theft screw is finally installed, is screwed rear anti-theft screw and is located in the stopper slot of inclined-plane telescopic head.
