Embodiment
Below, with reference to the accompanying drawings preferred implementation of the present invention is described.
The 1st, the box main body of opening 2 is set in front, the 3rd, open and close the door leaf door of described opening 2.Box main body 1, door leaf door 3 are the thermoplastic resin formations by the polybutylene terephthalate (PBT) resin (PBT) that can utilize again after discarded, polycarbonate resin etc.
And, form the heavy section 4 that strengthens usefulness at the inner face of the platen surface 31 of described door leaf door 3, in this heavy section 4, hollow bulb 5 is set.That is, the peripheral side at the inner face of the platen surface 31 of door leaf door 3 forms heavy section 4 as shown in Figure 1 and Figure 2, in this heavy section 4 hollow bulb 5 is set, thereby does not in very large range have the thicker part of thickness of slab self.In addition, hollow bulb 5 is when being shaped, and is positioned at the place that will form heavy section, adopts so-called gas auxiliary law (Gas-assist), injecting gas and the part that forms continuously.
Because this electric device storage box of the present invention, be on the platen surface 31 of the door leaf door 3 that constitutes by thermoplastic resin, be provided with and formed the electric device storage box that strengthens with heavy section 4, even therefore platen surface 31 walls are thinner, also can increase its rigidity, make the intensity grow of door leaf door 3.So owing to do not need to add strengthening material such as glass fibre, the usability again after discarded is good.And then, owing in strengthening the heavy section 4 of usefulness, form hollow bulb 5,, therefore can not produce indenture and make the good looking appearance deterioration so thickness of slab self does not have thick part.In addition, though this execution mode is illustrated heavy section and the hollow bulb that forms at the door leaf door,, also can be formed at box main body when box main body the time for more shallow shape.
In addition, the heavy section 4 of described enhancing usefulness is that the corresponding place of the front end face 21a of opening frame portion 21 forms on the platen surface 31 of door leaf door 3, with the end face of the opening 2 of box main body 1.And, at the upside of heavy section 4, be configured in the liner 6 that docks with the front end face 21a of opening frame portion 21 when closing door leaf door 3.That is, between the deckle board portion 7,7 that erects in the upside both sides of heavy section 4, liner 6 is installed, can be made the thickness attenuation of liner 6 with the thickness part of the heavy section 4 that is provided with hollow bulb 5.In addition, with the limit of the hinge adjacency of door leaf door 3 on, with the same in the past, groove shape flange 302 (with reference to Fig. 6) is set in the inboard of platen surface 31, erect to support in the central authorities of this flange 302 and use flange, make liner be supported on the front end of this support usefulness flange.Because itself and hinge adjacency, so the support that has reduced the front end face 21a of opening frame portion 21 and be arranged on these flange 302 central authorities is with the dislocation between the flange front end, like this, liner just can not enter support that the central authorities at this flange 302 are provided with flange and groove shape flange 302 between.
Though owing to central nearer place at the distance goods, resin can distribute equably, the inlet that thermoplastic resin therefore is set promptly enters the mouth 34 place preferably at this place, but, under the situation of injecting gas, since slow more the closer to inlet 34 curing, therefore preferred place at the ozzle 35 that promptly enters the mouth near the gas inlet.This ozzle 35 that enters the mouth, be arranged on heavy section 4 near, still owing to comparing more close central side place with heavy section 4, the machine of door leaf door is installed effective area and is diminished, after therefore being shaped, at the upside of heavy section 4, promptly at the configuration section of liner 6, it is concavo-convex that the surface becomes, so be not preferred.Therefore, inlet ozzle 35 is arranged on heavy section 4 and compares more close outer circumferential side.But, since in solidification process therefore injecting gas, the gas thickness of slab part that enters the door leaf door from heavy section 4 sometimes.Thus, compare with the heavy section 4 of surface plate 31 more close in all sides place slot part 36 is set.By this slot part 36 is set, then the part that thickness of slab is thin begins to solidify, and like this, can prevent the gas from inlet ozzle 35, at the inlet of thermoplastic resin or be used to install handle hole portion 37 around revolution.
Fig. 8, Fig. 9 are near the figure the expression inlet ozzle 35, by limiting heavy section 401 also being provided with up and down of inlet ozzle 35, then from the inlet ozzle 35 gas as shown by arrow A, go up smoothly current downflow, so can prevent at the inlet of thermoplastic resin or be used to install handle hole portion 37 around revolution.
In addition, at the side of box main body 1 board, the impress 41 that uses when being provided for that the hole that the machine in ventilation fan and skylight 51 etc. is installed usefulness carried out perforate.By impress 41 being set, can knowing position of opening, thereby can not influence the attractive in appearance of box main body 1 outside at the side board.
In addition, on box main body 1,, form the crest line 42 that central authorities exceed slightly as Fig. 1, Figure 10 and shown in Figure 12.This crest line 42 is to be used to make rainwater to be divided right and left by this line fall, thus the mechanism that rainwater is not stockpiled on box main body 1.
And then, form the outer portion 43 that covers door leaf door 3 up and down at the open end of box main body 1.By this outer portion 43 is set, can directly contact rainwater at the place, end, top of door leaf door 3, thereby improve water resistance.Why outer portion 43 is arranged on upper-lower position, being because door leaf door 3 is being taken off from box main body 1, box main body 1 being turned upside down and door leaf door 3 is installed, still is that the right side is when opening the door leaf door thereby select a left side to open the door leaf door, in any case, can make it have outer portion 43 at upside.
In addition, the 32nd, in the outer peripheral edges of door leaf door 3 towards inboard and frame portion, the 33rd that be provided with, locking device.And, in the central authorities of the back side of box main body 1 board 13, form the stepped recess 14 on two rank, on the first rank recess 16 of this recess 14, can embed install machinery and install with base 8.And, on second recess 17 of described recess 14, the shortcoming portion 18 of the chimeric usefulness of support is set from its side to the part that is equivalent to base installing hole 15, stretch out sheet 19 what the chimeric front face side with shortcoming portion 18 of support was provided for preventing coming off, loading and unloading are equipped with the nut support 9 of having assembled nut 9a freely in this shortcoming portion 18, bolted joints screw 8b on this nut 9a, thereby install machinery mounting seat 8.Thus, as shown in figure 10, because the lower end of machine mounting seat 8 is supported on the 16a of the portion of getting out of a predicament or an embarrassing situation of recess 16, so only just can make it can bear big load by carrying out bolted joints in two places of machine mounting seat 8.
If both sides at described recess 14, the a plurality of base installing holes 15 of upper and lower settings, then since the position of the bolted joints of machine mounting seat 8 can change, so when setting in advance bolted joints on machine mounting seat 8 and interference take place with hole 8a and install machinery, can open bolted joints in other positions of machine mounting seat 8 and use the hole, thereby avoid this situation.
In addition, as previously mentioned, by at a plurality of base installing holes 15 of the both sides of recess 14 upper and lower settings, then between two wing base installing holes 15,15 of the recess 14 that is in opposed locations, as shown in figure 12, IEC guide rail 10 can be installed, and, the machine mounting seat 8 of local usefulness is mixed with IEC guide rail 10 and install.
As mentioned above, Fig. 1～3 and Figure 10～13 are to be the explanation that example is carried out with vertical electric device storage box, and Fig. 4～9th is the explanation that example is carried out with horizontal electric device storage box.Though profile has vertical and horizontal difference, essential structure is identical, can select to use according to purposes.
