## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an assembling structure and more particularly to an assembling structure for a filtration set.
2. Description of Related Art
A conventional assembling structure for a filtration set comprises a main case, a frame and a filter set. The main case has a front opening. The filter set is assembled onto the frame. The frame with the filter set is received into the main case via the front opening. The filter set has a plurality of filter cases. The filter cases are connected in series connection via a plurality of connecting units. Each connecting unit is connected between each two adjacent filter cases. The filter cases connected in series connection are assembled onto the frame.
Under this arrangement, when a user wants to detach one filter case from the filter set, the user pulls the frame out from the main case; and than, the user detaches the two connecting units at two sides of the above one filter case; as a result, the above one filter case is detached from the filter set.
However, the conventional assembling structure for a filtration set still has two disadvantages as following:
First, the above assembling operation (or detaching operation) is complicated, because the user must assemble (or detach) the connecting units at first.
Second, when the user assembles (or detaches) the filter cases, the connecting units might be lost.
The present invention has arisen to mitigate and/or obviate the disadvantages of the conventional. Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1-4, an assembling structure for a filtration set in accordance with the present invention comprises a filter set 1 having a plurality of filter cases 2. The filter cases 2 are assembled together. An assembling portion 21 is extruded on an outer surface of each filter case 2. The assembling portion 21 extends from a top to a bottom of each filter case 2. The assembling portion 21 of one filter case 2 is used to be connected to the assembling portion 21 of another corresponding filter case 2, so as to assemble each two adjacent filter cases 2 (as shown in FIG. 3). At least one assembling plate 22 has two ends which are respectively extruded from each side of the assembling portion 21 and the outer surface of the corresponding filter case 2. The assembling plate 22 has a positioning block 23 at a periphery thereof. A plurality of bolts 24 is used to be inserted through the positioning block 23 of each filter case 2.
Under this arrangement, when a user wants to assemble the filter cases 2 together, the user connects the assembling portion 21 of one filter case 2 to the assembling portion 21 of another corresponding filter case 2; then, the user aligns one positioning block 23 of one filter case and another corresponding positioning block 23 of another corresponding filter case 2, so that one positioning block 23 abuts against another positioning block 23; thereafter, the user inserts the bolt 24 through one positioning block 23 and another corresponding positioning block 23 so as to assemble one filter case 2 to another corresponding filter case 2.
Under this arrangement, when a user wants to assemble the filter cases 2 together, the user aligns one positioning block 23 of one filter case 2 and another corresponding positioning block 23 of another corresponding filter case 2, so that one positioning block 23 abuts against another positioning block 23; then, the user inserts the bolt 24 through one positioning block 23 and another corresponding positioning block 23 so as to assemble one filter case 2 to another corresponding filter case 2.
The detail of the above assembling is shown as FIGS. 1 and 3. One assembling portion 21 of one filter case 2 is attached to another assembling portion 21 of another filter case 2, so that each assembling plate 22 of one filter case 2 abuts against each corresponding assembling plate 22 of another filter case 2; each assembling plate 22 has an assembling groove 25 defined at the periphery thereof; the assembling groove 25 is adjacent to the corresponding positioning block 23; a shape of the assembling groove 25 is corresponding to each positioning block 23; the positioning block 23 of one filter case 2 is partially received into the assembling groove 25 of another filter case 2, so that each positioning block 23 of one filter case 2 is aligned with and abutted against each positioning block 23 of another filter case 2; each bolt 24 is inserted through each corresponding positioning block 23 of one filter case 2 and each corresponding positioning block 23 of another filter case 2 so as to assemble one filter case 2 to another filter case 2.
Referring to FIGS. 5-6, when the user wants to further assemble one pair of assembled filter cases 2 to another pair of assembled filter cases 2, the user aligns the above two pairs of assembled filter cases 2, and abuts one pair of assembled filter cases 2 against another pair of assembled filter cases 2, so that each assembling plate 22 of one pair of assembled filter cases 2 abuts against each corresponding assembling plate 22 of another pair of assembled filter cases 2; and then, a connecting plate 3 is set onto the assembling plates 22 of the above two pairs of assembled filter cases 2; wherein, the connecting plate 3 has a plurality of through holes 31 opened thereon, and each assembling plate 22 of the above two pairs of assembled filter cases 2 has one threaded hole 26 which is corresponding to the corresponding through hole 31; finally, a plurality of screw units 4 is provided and each screw unit 4 passes through the corresponding through hole 31 so as to be screwed into the corresponding threaded hole 26, so that the above two pairs of assembled filter cases 2 are assembled to each other (the amount of the assembled filter cases 2 is not limited by the present invention).
Furthermore, referring to FIGS. 2-3, 4 and 7, a side guide pipe 17 is assembled on the assembling portion 21 of one filter case 2; two ends of the side guide pipe 17 both communicate with an inside of one filter case 2; the two ends of the side guide pipe 17 of one filter case 2 is inserted into the assembling portion 21 of another filter case 2, so that the two ends of the side guide pipe 17 of one filter case 2 also communicate with an inside of another filter case 2. Therefore, a volume of water flows from one filter case 2 to another filter case 2 so as to be filtered via an inside filter (not shown). Referring to FIGS. 4 and 7, at least one bottom guide pipe 18 is assembled at a bottom of the filter case 2; the bottom guide pipe 18 communicates with the inside of the filter case 2; a further pipe is connected between the bottom guide pipe 18 of one filter case 2 and the bottom guide pipe 18 of another filter case 2.
