Embodiment
The utility model provides straight-down negative diffuser plate fixed structure, for making the purpose of this utility model, technical scheme and effect clearer, clear and definite, referring to accompanying drawing examples, the utility model is further described.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
A kind of straight-down negative diffuser plate fixed structure, as depicted in figs. 1 and 2, it comprises a diffuser plate 10, one for carrying the mesochite 30 of described diffuser plate 10, wherein, its also comprise one be set in described diffuser plate 10 outer and with described mesochite 30 clampings for fixing described diffuser plate 10 middle frame support 20, described middle frame support 20 sides and described mesochite 30 can adopt general grafting clamping structure, the madial wall of described mesochite 30 is provided with for placing the support base of described diffuser plate 10, diffuser plate 10 is placed on described mesochite 30 when interior, almost concordant on both height, the preferably concordant setting of side of the side of middle frame support 20 and described diffuser plate 10, it adopts metal mesochite, between described mesochite 30 and middle frame support 20 and between described diffuser plate 10 and middle frame support 20, be respectively arranged with the clamping structure moving for limiting described diffuser plate 10, it fixes mutually, restriction diffuser plate 10 upper and lower, move left and right.
Concrete, as shown in Figures 3 to 5, a side of described mesochite 30 is provided with for assembling the location flanging 310 of described diffuser plate 10, and a side of described diffuser plate 10 is provided with the locating notch suitable with described location flanging 310; Described diffuser plate 10 sides are provided with location short slot 110, described middle frame support 20 is provided with the reference column 210 that for limit described diffuser plate 10 move left and right suitable with described location short slot 110, and location flanging 310, locating notch 110, reference column 210 all can be set to a plurality of.After loading onto middle frame support, can guarantee that diffuser plate 10 cannot move in X, Y-direction, while middle frame support can be pushed down diffuser plate 10 diffuser plate 10 also cannot be moved in Z direction, thereby plays fixedly diffuser plate 10 effects.Meanwhile, mesochite 30 and middle frame support 20 play location and fixing effect jointly, make diffuser plate 10 assembling more simple, quick, and avoided that original locate mode may occur cross location or diffuser plate 10 dimension precision requirement crossed to the problems such as height.
For diffuser plate convenient for assembly, preferably, only the side at described mesochite 30 is provided with a described location flanging 310, and a side of diffuser plate 10 that is provided with described locating notch 110 is corresponding with a side of mesochite 30 that is provided with described location flanging 310, during assembling, only a side of the diffuser plate with locating notch need be corresponded to this and have one of location flanging and be sidelong and put, easy and simple to handle, this location flanging can fold by cut technique on mesochite.
Preferably, described locating notch 110, for being arranged on 2 locating notches 110 on described diffuser plate 10 limits, the left and right sides, certainly, also can arrange at the dual-side up and down of described diffuser plate 10 2 locating notches, or at 4 sides, locating notch is set simultaneously.
