Abstract
The utility model discloses a well cover of water supply wells, dry wells, cable wells, etc. for cities, particularly a theft-proof well cover with the theft-proof function. A furcate hinge is arranged between the well cover and a fixing loop of an outer edge, and the well cover, the hinge and the fixing hoop of an outer edge are connected into a whole by two pin shafts and are not easy to separate; consequently, the utility model has certain theft-proof function. When opened, the well cover can be turned to the level position of 180 DEG, so the utility model does not hinder the construction and does not affect the security of passengers and building workers.
Description
Technical field
The utility model relates to a kind of well lid, refers in particular to a kind of well lid with anti-theft feature.
Background technology
The well lid of the upper and lower well in the city, communication cable well, power cables well etc. is a kind of casting iron well lid mostly at present, and its intensity height is difficult for rolling bad, and is therefore used in a large number.But cast iron is a kind of recoverable metal, and the unprincipled fellow often steals it, and public property is incurred loss, and pedestrian's safety is subjected to into the side of body.The well lid of recyclable material occurs though have not at present, and its intensity often can not be born rolling of a large amount of vehicles in city, damages easily.A kind of well lid is arranged in the market, and it still is a cast iron materials, and its end of center line on the well lid outer rim has a projection, and the lateral aperture perpendicular to the well lid center line is arranged on the projection; The boss that one hollow is arranged on the external fixation circle, also have on the boss with well lid on the corresponding hole of horizontal connecting hole, in the hole of well lid and external fixation circle boss, insert a bearing pin, well lid and external fixation circle are linked together.So just be not easy to go adrift.But because structure interval can not be excessive between the boss of well lid and external fixation circle, excessive projection or pit can not be arranged, otherwise can influence pedestrian's safety, the well lid of this structure can not be turned to 180 ° when opening, that is: can not horizontal positioned, can only keep 90 °-120 ° angle with well head.Just not too safe when this well lid carries out in the well operation after opening, be prone to accidents.
Summary of the invention
Well lid can be turned to horizontal level when the technical problems to be solved in the utility model provides a kind of opening, and have the well lid of certain anti-theft feature.
The utility model is achieved in that a kind of anti-stealing manhole cover, comprise well lid, external fixation circle and bearing pin, an end of center line has a projection on the well lid outer rim, lateral aperture perpendicular to the well lid center line is arranged on the projection, the boss that one hollow is arranged on the external fixation circle, horizontal connecting hole perpendicular to the well lid center line is also arranged on the boss, in the cannular boss on the retainer plate and between the projection of well lid outer rim a hinge is arranged outside, well lid and external fixation circle are linked together by bearing pin.
Described hinge is the fork-shaped hinge, and the width of the cavity of its external width and external fixation circle boss is corresponding, and the width of the inner width of jaw and well lid projection is corresponding; The fork handle of hinge and jaw position respectively have one with the boss of external fixation circle on the hole and the corresponding hole, hole on the projection of well lid.
Hole on the boss of described hinge and external fixation circle is welded as a whole after inserting bearing pin.
The technological progress that the utility model is obtained is: because the utility model has adopted above-mentioned hinge to connect the structure of well lid and outer rim retainer plate, when well lid is opened, well lid and hinge rotate around the bearing pin on the outer rim retainer plate, hinge reaches the upright position, well lid can overturn 180 °, the position that is up to the standard is set level, and like this operating personnel and pedestrian is compared safety; The well lid of this kind structure in addition, because the outer rim retainer plate is fixed on behind pavement construction in the ground, well lid and outer rim retainer plate are connected as a single entity by bearing pin and hinge, bearing pin is again to weld deadly, can not get with the method for routine, so have certain anti-theft feature.
Description of drawings
Below in conjunction with drawings and Examples the specific embodiment of the present utility model is described in further detail.
Fig. 1 is a partial cutaway schematic of the present utility model.
1 is well lid, and 2 is the bearing pin between well lid and the hinge, and 3 is hinge, and 4 is the bearing pin between hinge and the outer rim retainer plate, and 5 is the outer rim retainer plate.
The specific embodiment
Among the embodiment as shown in Figure 1, 2, stretch out a projection in the left side of the circular flat of well lid 1, the both sides plane parallel of this projection is shaped on one perpendicular to the two sides of projection and the hole of well lid center line in the center line of well lid 1 on projection; Between the boss of the projection of well lid 1 and outer rim retainer plate 5, a fork-shaped hinge 3 is set, respectively have on the fork handle of fork-shaped hinge 3 and the jaw one on the boss with outer rim retainer plate 5 the hole and the corresponding hole, hole on the projection of well lid 1; Be inserted in the above-mentioned hole with bearing pin 2,4 during assembling, well lid, hinge and outer rim retainer plate are linked together.After assembling finishes, again that bearing pin 2,4 two ends are dead with the welding rod welding, if do not adopt destructive means like this, just well lid 1 can not be separated from outer rim retainer plate 5. Bearing pin 2,4 of the present utility model all adopts high strength steel to process, and has increased the difficulty with its destruction more.
