Description
Technical field
The utility model belongs to a kind of highway ancillary service technical field, specifically relates to a kind of highway manhole cover structure.
Background technology
Well lid is each city requisite facility articles for use in urban construction, and ground various inspection well head needs to utilize well lid to cover, and at present, the well lid be widely used in municipal engineering exists following problem in actual use:
One, well lid is fastened on manhole cover base, does not arrange immobilising device each other, when motor vehicles are pressed in well lid avris, is easy to make well lid in manhole cover base top offset, rollover, its consequence quite dangerous;
Two, manhole cover base does not arrange fixing hole, itself and road locate mode only choke around it by ground surface material, once road surface occurs damaged around manhole cover base, manhole cover base then becomes the form be placed on well head, the same quite dangerous of its consequence;
Three, well lid and manhole cover base all adopt metal to obtain, such well lid is very easy to be stolen by lawless person, and the well that lost well lid when supplementary well lid not in time, be very easy to occur the traffic accident such as damaged vehicle and pedestrian's tumble injury, even injure the security of the lives and property of people.
Utility model content
The technical problems to be solved in the utility model is to provide simple and antitheft, the safe highway manhole cover structure of a kind of structure.
Content of the present utility model comprises pit shaft, well lid top board and well lid cylinder, described well lid top board and well lid cylinder composition well lid, described well lid cylinder lower end is hinged with lock, described pit shaft comprises pit shaft shoulder, opening groove and the blockade groove of accepting well lid cylinder, described opening groove and blockade groove are arranged on the side of pit shaft shoulder, described opening groove to be connected setting with blockade groove, and the height of described opening groove is H
1, the height of described blockade groove is H
2, the height of described lock is H, and the length of described lock is L, H < H
2< H+L < H
1.
The top of described opening groove and blockade groove has the projection of arc.
Described lock and well lid cylinder adopt hinge hinged.
The height of described opening groove is 1-5cm.
The beneficial effects of the utility model are, the utility model in use, lock is placed on immediately below well lid cylinder, the position aiming at opening groove is put down, and then under force, lock is along hinged axis of rotation, lock enters in opening groove, then rotate the utility model, lock is entered into and blocks groove pinning, because the size of blocking groove meets H < H
2< H+L, when therefore directly up lifting well lid in this case, blocks groove and can block lock, cause it not take out.When have need take out well lid time, rotary well cover, make lock aim at opening groove, now, lift well lid time, opening groove can not block lock, conveniently takes out well lid.
The top of opening groove of the present utility model and blockade groove has the projection of arc, convenient stressed when taking out.
The utility model has blockade and open two states, when the people stolen does not know state, prevents thief from stealing, prevents natural force from opening well lid on the other hand, such as prevent flood from being gone out by well lid when Flooding, ensure safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of blockade groove of the present utility model.
In the drawings, 1 pit shaft, 2 well lid top boards, 3 well lid cylinders, 4 locks, 5 opening grooves, 6 pit shaft shoulders, 7 block groove.
Detailed description of the invention
As depicted in figs. 1 and 2, the utility model comprises pit shaft 1, well lid top board 2 and well lid cylinder 3, described well lid top board 2 and well lid cylinder 3 form well lid, described well lid cylinder 3 lower end is hinged with lock 4, described pit shaft 1 comprises pit shaft shoulder 6, opening groove 5 and the blockade groove 7 of accepting well lid cylinder 3, described opening groove 5 and block the side that groove 7 is arranged on pit shaft shoulder 6, described opening groove 5 and block groove 7 and to be connected setting, the height of described opening groove 5 is H
1, the height of described blockade groove 7 is H
2, the height of described lock 4 is H, and the length of described lock is L, H < H
2< H+L < H
1.
The top of described opening groove 5 and blockade groove 7 has the projection of arc.
Described lock 4 and well lid cylinder 3 adopt hinge hinged.
The height of described opening groove 5 is 1-5cm.
The utility model in use, lock 4 is placed on immediately below well lid cylinder 3, the position aiming at opening groove 5 is put down, then under force, lock 4 is along hinged axis of rotation, and lock 4 enters in opening groove 5, then rotates the utility model, make lock 4 enter into blockade groove 7 to pin, because the size of blocking groove 7 meets H < H
2< H+L, when therefore directly up lifting well lid in this case, blocks groove 7 and can block lock 4, cause it not take out.When have need take out well lid time, rotary well cover, makes lock 4 aim at opening groove 5, now, lift well lid time, opening groove can not block lock 4, conveniently takes out well lid.
The top of opening groove 5 of the present utility model and blockade groove 7 has the projection of arc, convenient stressed when taking out.
The utility model has blockade and open two states, when the people stolen does not know state, prevents thief from stealing, prevents natural force from opening well lid on the other hand, such as prevent flood from being gone out by well lid when Flooding, ensure safety.
