Description
The utility model belongs to the ground well lid.
Existing ground well lid is as the ground well lid of underground installations such as upper and lower water, gas flue, cable, though they have used and have used till today for many years, but they still exist a shortcoming, promptly do not have anti-theft measure, easily lose, especially even more serious in regional robbed or burgled phenomenons such as the combination areas of city and country.Ground well lid stolen caused the loss of a large amount of public properties, and be stolen as Communication Equipment, and underground installation damage etc. also cause car have an accident and pass by on one's way pedestrian's injures and deaths.People wait in expectation and prevent the stolen technical scheme of ground well lid.
The purpose of this utility model is in order to solve above-mentioned existing problems, a kind of antitheft ground well lid to be provided.It can prevent the stolen of ground well lid effectively, and can only just can open the ground well lid under the situation that is equipped with special tool.
In order to achieve the above object, the utility model comprises ground well lid and ground well outer ring, it is characterized in that in the ground well lid of the two junction column type being housed bumps pearl, the front top that column type is bumped pearl be inserted into corresponding outer ring, ground well outer ring groove in, in bumping pearl rear end ground well lid, column type has the vertical spacing hole, plug-in mounting one spacer pin in spacing hole.
For tighten that column type is bumped pearl and when the plug-in mounting spacer pin its shaft generation elastic deformation, its shaft of spacer pin is the circular arc that concaves, and has groove on its shaft.
For the ease of special tool dismounting spacer pin, spacer pin top can connect one and open sleeve pipe, and opening has a blind hole (the plug-in mounting special tool is used) on the sleeve pipe, hard hat is housed in the blind hole.
For the ease of lubricated, column type is bumped on the pearl body and is had oil groove, bumps pearl in column type and with the contacted position of well lid, ground sheath is housed.
Column type bumps pearl and spacer pin can be in (2-6) individual scope in ground well lid circle distribution quantity.
Advantage of the present utility model is: cover the outfit column type at ground well and bump pearl and spacer pin, can prevent the stolen phenomenon of ground well lid effectively, thereby can avoid the damage of the underground installation that brings because of the ground well lid is stolen, the generation of the accident of car and the phenomenons such as casualties of passing by on one's way.And in the time of need opening the ground well lid, have only under the situation that is equipped with special tool and just can open.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a partial sectional view of the present utility model.
(1) column type is bumped pearl; (2) sheath; (3) spacer pin; (4) open sleeve pipe; (5) protective jacket; (6) well lid; (7) groove; (8) spacing hole; (9) oil groove; (10) ground well outer ring; (11) outer ring groove.
Referring to Fig. 1, the edge of ground well lid (6), have a transverse holes in its body, sheath (2) is housed in it, column type is bumped in pearl (1) the plug-in mounting sheath (2), the front top (left end among the figure) that column type is bumped pearl (1) is inserted in outer ring corresponding with it groove (11), bump position, pearl (1) rear end (right-hand member among the figure) in column type, have a vertical spacing hole (8) on the ground well lid (6), plug-in mounting one spacer pin (3) in spacing hole (8), the shaft of spacer pin (3) is to be made by plastic material, its shaft is to be the circular arc that concaves, and also has groove (7) at its shaft, and spacer pin (3) top connects one and opens sleeve pipe (4), opening on the sleeve pipe (4) has a blind hole, a hard hat (5) spiral-lock is arranged in blind hole.
When ground well lid (6) is installed, earlier column type being bumped pearl (1) inserts in the outer ring groove (11), plug-in mounting upper arresting pin (3) then, in the plug-in mounting process, spacer pin (3) end touches column type when bumping pearl (1), and elastic deformation takes place spacer pin (3) makes it reach the installation site of regulation, at this moment, column type bump pearl (1) after correct in the arc surface of spacer pin (3) shaft, column type is bumped pearl (1) and promptly is lockable like this, has reached antitheft purpose.
During dismounting, take off protective jacket (5), special tool is inserted in the blind hole of opening sleeve pipe (4), upwards extract then, since have groove (7) on the shaft of spacer pin (3), in withdrawal process, spacer pin (3) shaft generation elastic deformation, thereby spacer pin (3) extracted, so just can open ground well lid (6).
