Abstract
The utility model discloses a variable top cover of an American type box. A waterproof edge (21) extending outwards is arranged at the periphery of a top cover body (2), so that edges at the periphery of the variable top cover of the American type box extend out of the box body. Thus, rainwater does not flow into the box body when falling on the variable top cover of the American type box, and falls on the ground through an edge of the variable top cover of the American type box. Therefore, the American type box has a waterproof effect, and a safety performance of the American type box is improved.
Description
Technical field
The utility model belongs to American-type box and becomes the field, relates in particular to a kind of American-type box and becomes top cover.
Background technology
The tradition American-type box becomes top cover and adopts the cuboid housing structure, become casing concordant (as shown in Figure 3) with American-type box around the American-type box change top cover, if run into rainwater, rainwater will become top cover from American-type box and trickle to American-type box change casing, and then enter in the interior equipment of casing, because American-type box becomes the inner high voltage equipment that is, if there is water to enter, will cause very large harm to equipment, not only can cause the infringement of equipment, even have an accident, cause personnel's injures and deaths.
The utility model content
Become the defective that top cover easily allows rainwater enter for traditional American-type box, technical problem to be solved in the utility model provides a kind of American-type box that can prevent that rainwater from entering and becomes top cover.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of American-type box becomes top cover, comprises the top cover body, and the top cover body links to each other with casing, is provided with outward extending waterproof edge around the top cover body.This waterproof edge so that American-type box become top cover around exceed casing around, around the waterproof edge to downward-extension and inwardly curling.Top cover body and casing are for being threaded.American-type box becomes top cover and can be formed by sheet stamping, and manufacture craft is simple.
The utility model has the advantage of, the border exceeds the border of casing around the American-type box change top cover, its effect is equivalent to eaves, when rainwater is fallen on the American-type box change top cover, become top cover edge all around with flowing to American-type box, fall on the ground from edge all around again, can not become the top cover edge via American-type box flows on the casing, American-type box becomes top cover and is made by a thin plate, changed the structure of original cuboid, make an alternating floor thin-walled between box house and the outside air, radiating effect is better, more saves material simultaneously.
Description of drawings
Fig. 1 is the structural representation that a kind of American-type box of the utility model becomes top cover;
Fig. 2 is the structural representation that Fig. 1 American-type box becomes top cover;
Fig. 3 is the prior art structural representation;
Mark among the above-mentioned figure is: 1, casing, 2, the top cover body, 21, waterproof edge.
The specific embodiment
Fig. 1 and Fig. 2 are the structural representation that a kind of American-type box of the utility model becomes top cover, comprise top cover body 2, and top cover body 2 links to each other with casing 1, are provided with outward extending waterproof edge 21 around the top cover body 2.Also inwardly curling to downward-extension around the waterproof edge 21.Top cover body 2 and casing 1 are for being threaded.After adopting such structure, the border exceeds the border of casing 1 around the American-type box change top cover, its effect is equivalent to eaves, when rainwater is fallen on the American-type box change top cover, become top cover edge all around with flowing to American-type box, fall on the ground from edge all around again, can not become the top cover edge via American-type box and flow on the casing 1.American-type box becomes top cover to be made by a thin plate, has changed the structure of original cuboid, makes an alternating floor thin-walled between casing 1 inside and the outside air, and radiating effect is better, more saves material simultaneously.To downward-extension and inside curling the wider of outer eaves that make, reach better waterproof effect around the waterproof edge 21.
After adopting such structure, American-type box is become have good waterproof effect, improved safety performance, save simultaneously material, radiating effect also gets a promotion.
The above has carried out exemplary description to the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
