(one).

Through screws (26), located in each corner of the assembly, support the outer surface plate (25), the chassis (3) and the seal (6) with the upper flange (2) of the bowl (1) , whose screws, running through corresponding lower cylindrical lugs (27) are fixed by nuts (28) covered, below, by plugs
(29).

This cover (9) is constituted by a frame on which fits a plate (30) that forms the upper face external of said lid, and that will be in contact with the outside and positioned at ground level, so it will be elaborated, just like that the outer surface plate (25), of high material wear resistance

In its front part, the cover (9), in addition to dispose of the two front arms (8), have all three openings (31) and (32) (see figure 6), where the nails (19) and (20) of the latch latch (18).

Under the lateral openings (31) the front arms (8) are located, while under the central opening (32) there is a tooth (33) with an inclined front face, which, when closing the cover (9), will rest on the inclined upper face of the central nail (19) causing the backward movement of the latch (18) and allowing the automatic closing of the
top.

Once this action is finished, the latch (18) returns to its closed position pushed by springs (22), leaving the nails (19) and (20) positioned inside the openings (32) and (31), and thus, perfectly closed the cover (9).

When the lid (9) must be opened, it will be done move the latch (18) backwards by operating manually highlight (21) in this direction, so that the nails (19) and (20) will release the cover (9), whose front arms (8), will be driven by the disks (10), thanks to the action of the springs (11), raising the cover (9) with them.

These front arms (8), which when the cover (9) is closed are housed inside the hollow lugs (7), have in their lower front part two recesses (34), by way of fittings, where the side nails (20) of the latch (18) when the cover is positioned, according to figure 13, with the precise inclination so that the plug (35) and the cable (36) can be placed, the cover being fixed and locked in that position by the action of the mentioned nails (20) introduced in the recesses (34) of the arms
(8).

When you want to unlock the cover, it will be enough with actuate the latch (18), as is done when proceeding to the opening of said cover (9).

The bucket (1) has, on the outside of its faces lateral a series of vertical recesses (37) in which the operator can practice easily and using the one that most interested in a through hole in which to install the press-tow (38) protecting the entrance of the conduit (39) of the electric cable, which will allow its penetration into the lower inner part of said tray (1) and the flanged suitable electrical cables in the electrical mechanism (5).

The press-tow has been represented in figure 9, which is constituted by the through bushing (38a), provided with the inner fixing nut (40) and the outer nut (41) located on the conduit itself (39).

On the side face of the bucket (1) and corresponding to the drain collector (13), there is another recess (42) that the operator will drill at the moment when the evacuation duct must be installed
(14).

Couples of vertical nerves, section in "L" (43), which has in the edges of its lateral faces the cuvette (1), allow if the coupling of the cuvette is desired with another one next door (Fig. 16), when faced with the couple corresponding nerves of the other cuvette, a suitable clamp (44) which is disposed inside said vertical ribs (43) of section in "L".

It is evident, therefore, that the structure of the recessed box of the invention, allows the sealing to be practically total and absolute since, when the lid is closed and therefore forming a plane with the upper surface of the box and flush the assembly with the floor is hermetic between the cover and the chassis thanks to the gasket (16) and even when there would be a small amount of liquid it would slide through the bottom slope to the drain (12) and then fall in the small tank (13) of the base (3a) of the box (1) which, to in turn, communicates with the outside through the drain (14).

When the box is open, the performance is the same as the evacuation of water or liquid following identical road.
