Fig. 5 to Fig. 7 represents the grille 122 of second embodiment of drainage channel.As above-mentioned described with reference to Fig. 1-4, grille 122 is suitable for being placed on the elementary cell.Therefore the elementary cell 12 according to first embodiment also can be used for second embodiment, and is as described below, without any the material change.Grille 122 upsides are to be provided with the grille 22 identical or similar modes of first embodiment shown in Figure 1.Fig. 5 represents the grille 122 of edge corresponding to the II-II line left part longitudinal profile of Fig. 1, and Fig. 6 represents the sectional view of edge corresponding to the grille 122 of the III-III line of Fig. 1.

Different with the grille 22 of first embodiment is that horizontal ribbed 132 of grille 122 extends on the whole width of grille 122, and grille 122 only is shelved on the stayed surface 21 of elementary cell 12 by horizontal ribbed 132 side part 132a.When the stayed surface 21 of grille 122 and elementary cell 12 is adjacent, not with the stayed surface 21 of the elementary cell 12 of grille 122 adjacency on, between every couple adjacent horizontal ribbed 132 terminal 132a, form the gap.

The difference of lid 122 and first kind of structure is, the structure difference of geared assembly 138,140.Although locking device 138,140 also has locking function, in second structure, second locking unit 144 is configured to the wedge lock part.In off position down, second locking unit 144 that is configured to the wedge lock part overlaps below first locking unit that is configured to elementary cell 12, with with first structure in first locking unit, 42 same or analogous modes be provided with, and also be configured for fin or the protuberance same or analogous mode of grading.

Similar with first structure, in second structure, second locking unit 144 also is positioned at the lower end 154 of ledge 134 or 136.But, different with first structure is, in second structure, second locking unit is configured to bar, this bar is parallel to the plane of grille 122 and extends on the whole width of grille 122, the

ledge

134 or 136 the width that wherein support second locking unit 144 are much smaller, specifically as shown in Figure 6 and Figure 7.

In all others, the structure of second embodiment corresponds essentially to the structure of first embodiment, therefore, does not need to further describe at this.

Yet, alternatively, it will also be appreciated that, can will be arranged at the high-tensile steel spring of bias voltage on this elementary cell on the direction of first locking unit by casting, this spring also can this grille downside or corresponding horizontal ribbed on described elementary cell engagement.

Can be seen also that by Fig. 2 and Fig. 8

depressed part

60 and 160 downsides in

lid

22 or 122 form, the jut 62 that correspondingly is arranged on the elementary cell 12 is engaged with.

In Fig. 2, with reference to first embodiment, depressed part 60 is illustrated by the broken lines with the jut 62 that links to each other, but only can see jut 62 in Fig. 5.In the first embodiment, the jut 62 of two mutual separation settings is set in place on the stayed surface 21 of the shoulder 20 at edge 19, so jut 62 stretches out (especially Fig. 5) from stayed surface 21.Therefore, in described embodiment, relevant depressed part 60 forms at the downside of the peripheral disc 26 of lid 22.Yet it is also envisioned that only to provide a jut 62 on elementary cell 12, a depressed part 60 correspondingly is provided on lid 22.The depressed part 60 and the jut 62 that can provide more than two pairs are provided.Normally, be positioned on each vertical side of elementary cell 12 with at least one jut 62 that meshes at a relevant depressed part 60 that forms on corresponding vertical side of lid 22.

In second embodiment, two vertical sides at grille 122, when lid 122 is placed on the elementary cell 12, each is formed two depressed parts by the gap that produces between lateral end part 133 and two the lateral end part 132a, lateral end part 133 is vertically widened grille 122, lateral end part 133 belongs to center transverse rib plate 132, and lateral end part 132a belongs to adjacent horizontal ribbed 132.The jut 62 that stretches out from the stayed surface 21 of elementary cell 12 is meshed with these gaps, and these gaps are identical with the function of depressed part 160 (referring to Fig. 5).In the embodiment illustrated, grille 122 vertically, the width dimensions setting of the lateral end part 133 of expansion, make described end portion adapt to the gap that forms between two juts 62 of paired setting substantially, therefore two juts 62 are substantially near the lateral end part of expanding 133, so that the tolerance of locking operation is as much as possible little, and realize required mobile preventing.But, alternatively or additionally, it is also envisioned that grille 122 vertically on the width of depressed part 160, can be corresponding to the width of the jut 62 that is meshed with described depressed part.

Like this, when

lid

22 or 122 is positioned on the elementary cell 12, not only first and second locking units guarantee that

lid

22 or 122 is meshed with elementary cell 12, and the jut on the elementary cell 12 62 also is meshed with

depressed part

60 or 160 at

lid

22 or 122 downsides.This layout comprises

depressed part

60 or 160 and the jut 62 that links to each other, thereby a kind of displacement prevent mean is provided, and

lid

22 or 122 is fixed in elementary cell 12, with vertically moving of avoiding not expecting.This undesirable moving specifically may be to cross lid 22 or generation in 122 o'clock at vehicle, and it can cause increasing the load of

locking device

38,40 or 138,140.On the other hand, by this displacement prevent mean that jut 62 and relevant

depressed part

60 or 160 constitute, can also be used to make geared

assembly

38,40 or 138,140 to separate.

Above-mentioned

depressed part

60 or 160 and being provided with of jut 62 be used for substantially vertically can not locking

grille

22 or 122 with being shifted.

For laterally locking, need other measure with being shifted.In the grille 122 according to second embodiment, this measure occurs with the form of extension 164.As shown in Figure 7, these extensions 164 combine integratedly with horizontal ribbed 132 and extend downwards.Yet, alternatively, it is also envisioned that the diverse location that this extension can be arranged on the grille downside.Extension 164 has constituted the retainer of a kind of internal side wall part 19a of the edge 19 near adjacent elementary cell 12, adjacent with described edge below stayed surface 21 (referring to Fig. 3 and Fig. 8).Yet, it is also envisioned that length as the extension of retainer can make described ledge not only near the internal side wall part 19a at edge 19, also near the internal side wall part 17a that is connected following channel unit 17.
