Description

[Detailed Description of the Invention] The present invention relates to a water tank for storing liquid, and more particularly to a storage tank having a double structure in which the outer periphery of the water tank is surrounded by an outer box.

When enclosing the outer periphery of this type of aquarium to form a double structure, the aquarium 1 is used as a means for fixing the aquarium 1 and the outer box 2 as shown in Figure 1.
The outward flange 3 formed at the upper opening edge is overlapped and placed on the inward flange 4 formed at the upper opening edge of the outer box 2, and then both flanges 3 and 4 are screwed together with screws 5, etc. I was trying to tighten and fix it.

In the case of such a configuration, it is preferable that when the liquid etc. that can be stored is undulated, the liquid etc. will penetrate into the tightening part of the screw 5 and cause rust to occur inside the outer box 2 which has a double structure. It wasn't something.

The present invention has been devised in view of this point, and one embodiment thereof will be described below with reference to the drawings.

Reference numeral 10, which has a rectangular top surface, is a storage water tank main body, which is mainly composed of a water tank main body 11 and an outer box 12 surrounding the water tank main body.

The water tank main body 11 is formed by press-molding a stainless steel plate material, and has an outwardly directed flange 1 that expands outward at the upper opening edge 13.
4, and an upright wall 15 formed by bending the outer peripheral end of the outward flange further upward is provided in succession.

Further, locking metal fittings 16, 16, 16.16 are fixed to the back surface of the flange located in the longitudinal direction of the outward flange 14 by spot welding.

The locking fitting 16 is made of a spring plate material, and has a fixing part 17 at one end.
is spot welded to the surface of the outward flange 14, and an elastic tongue piece 18 located at the other free end is biased toward the flange by a spring.

One of the outer boxes 12 surrounds the outer periphery of the aquarium main body 11 with a gap, and has a U-shape in plan. It consists of a cover plate 21.

The main body part 20 has an inward flange 22 on its upper open end on which the outward flange 14 of the aquarium main body 11 is superimposed, and the inward flange 22 has a hook provided on the aquarium main body 11. Cutouts 23, 23, 23.23 are formed into which the fasteners 16, 16, 16° 16 can be inserted.

Next, regarding the assembly order, first attach the locking fittings 16.16 (width dimension is Y') fixed to both sides of the aquarium body 11 to the notches 23.23 located further back than the opening 19 of the outer box 12.
(opposed width dimension is Y) from diagonally above (opening 19 side), and the inward flange 22 of the outer box 12 is held between the elastic tongues 18 of the locking fitting, and the water tank main body 11 Lower the rear end side (opening 19 side) and remove the outer box 12.
At the stage when the locking fitting 16 comes into contact with the inward flange 22 of the outer box 12, the opening 19 side of the outer box 12 is slightly expanded to connect the outer flange 14 of the aquarium main body 11 and the inward flange 22 of the outer box 12. When the opening 19 of the outer box 12 is in the overlapping position relationship, the opening 19 side of the outer box 12 is closed again to the fixed position, so that the locking fittings 16. That is, the locking fitting 16.1
The mounting dimension X' of 6 matches the outer dimension (insertion direction).

After that, the opening 19 of the outer box 12 is closed with a cover plate 21,
Assembly is completed by fixing both using screws 24° 24, legs 25, 25, etc.

Since the present invention is constructed as described above, there is no fear of water leakage from tightening parts such as screws as in the past, and the assembly workability is also good, and there is no possibility of looseness in various parts after assembly is completed. do not have.
