Abstract
The utility model provides a sewer well cover body with a theft-proof function, which is mainly composed of a well cover, a switching hanging claw which is installed on the bottom of the well cover, and a fixing hanging claw. The switching hanging claw is opened and closed by a special wrench so as to open and lock the well cover. The sewer well cover body with a theft-proof function is used for preventing the well cover from being stolen, preventing the well cover from being accidentally moved, and ensuring the safety of pedestrians and vehicles. The producing method is easy and convenient, and the use is convenient. The sewer well cover body with a theft-proof function is an ideal facility for building urban roads.
Description
The utility model relates to a kind of overburden and overburden framework of tunnel manhole shaft of sewer pipe special use.
At present, the sewer pipe well head lid in the most cities of China be cylinder iron, cast steel or the one-time formed product of prefabricated cement material.Compare with cement well lid, though the well lid that metal material is manufactured is not fragile, robbed or burgled phenomenon is more serious; In addition, various artificial and unexpected reasons also can cause moving of well lid, thereby well head is exposed.Owing to the stolen mistake of well lid or move and to cause the pedestrian to fall into that the sewer pipe well head is disabled or the incident of the human life of causing injury happens occasionally.Well head exposes also influences city vehicle traffic and sanitation of environment.
The purpose of this utility model is to invent a kind of well lid with antitheft and anti-shifting function.
But well lid body described in the utility model is a switch of evenly fixing at least one turn on the periphery of well lid 8 lower planes hangs pawl 7 and at least one fixing pawl 2 formation of hanging.It is by housing 1 that switch is hung pawl 7, and rotating shaft 5, compression spring 4 and extension pawl 3 constitute.Compression spring 4 is enclosed within the rotating shaft 5, and is installed in the housing 1.Compression both ends of the spring difference seat is on the bottom of housing 1 and the top of rotating shaft 5.The bottom outlet of housing 1 is passed in the lower end of this rotating shaft 5, and fixedly connected one is hung pawl 3.The lower end of housing 1 has straight trough 10, and hanging on the pawl 3 has the boss 11 that matches with straight trough.The upper end of rotating shaft 5 has one to have the convex platform of random geometry or to recessed slotted eye.Rotating shaft 5 is rotated arbitrarily in 5 axle center around the shaft with the extension pawl 3 that is fixed on its lower end.Above rotating shaft 5, on well lid 8, have a screw, and have a plug 9 to cooperate with it.All there is one to regulate bolt 6 in the fixing end that hangs pawl 2 and extension pawl 3.In order to open and seal well lid, the special-purpose wrench that the concavo-convex hole platform of end shape of needs and rotating shaft 5 upper ends matches.When the boss 11 on hanging pawl 3 embeds the straight trough 10 of housing 1 lower end, hang pawl 3 and hang on the lower platform 12 of well lid framework, spring 4 restores to the original state rotating shaft 5 can not be rotated, thereby pins well lid.For opening well lid, need to use special-purpose wrench, remove plug 9, promote rotating shaft 5 downwards, make the boss of hanging on the pawl 3 11 break away from straight trough 10, rotate wrench then, make and hang the platform 12 that pawl 3 breaks away from the well lid framework.
Fig. 1 is well lid of the present utility model and well lid frame construction schematic diagram.
Fig. 2 is that well lid lower plane switch is hung pawl and the fixing pawl distribution schematic diagram of hanging.
Fig. 1 is an embodiment of the present utility model.Foursquare boss is adopted in the platform hole of its rotating shaft 5 upper ends.The straight trough that points to the well lid center is adopted in the bottom of housing 1.When extension pawl 3 tangles the leave from office of well lid framework with fixing extension pawl 2, regulate bolt 6 respectively, well lid can not be thrown off easily, thereby reach the antitheft and anti-effect that moves.Fig. 2 adopts a switch to hang pawl 3 and two fixing embodiments of hanging pawl 2.Can adopt the one-time formed mode of metal casting in the enforcement, also can adopt and on original well lid, install and fix the mode of hanging pawl and switch extension pawl.
This anti-stealing manhole cover body adopts fixing extension pawl and switch to hang pawl and combines; reduce fabricating cost; described switch is hung pawl and only is made of four parts, and structure and manufacturing process are simple, adopts the adjusting bolt to make well lid can cooperate the well lid framework well; reach steadily fixing; be difficult for mobile effect, adopt special-purpose wrench to open and the sealing well lid, make well lid be difficult for stolen mistake; therefore this anti-stealing manhole cover body helps city municipal administration and road construction, helps sanitary protection.
