Technical field
The utility model is related to cleaning apparatus technical field, and more particularly to a kind of FFU easy for installation, good seal is installed
Structure.
Background technology
FFU full name are Fan Filter Units, and the Chinese meaning is " blower fan filtering unit ".It is general on the market at present
FFU is directly to lie on skeleton, and filter screen is pushed down using FFU itself gravity, the measure without any fastening.This is installed
The inferior position of structure is：
1. personnel need work high above the ground, step down on skeleton FFU place up, and need top leave enough spaces,
It is easy to personnel to stretch body work.
2. it can not be fully sealed between FFU and skeleton, extraneous dust can enter dust free room at unsealing, so as to have impact on
FFU filter efficiency, also have impact on the processing procedure quality of dust free room.
Therefore, it is necessary to provide a kind of new mounting structure to avoid problem above.
Utility model content
Main purpose of the present utility model is to provide a kind of FFU mounting structures easy for installation, good seal.
The utility model is achieved through the following technical solutions above-mentioned purpose：A kind of FFU mounting structures, including located at cabinet four
The mounting bracket in week, the mounting bracket is provided with some mounting holes, and the mounting bracket passes through the screw and spiral shell through the mounting hole
Mother is fixed on skeleton, and some rigid spacing shims and flexible sealing are clamped between the mounting bracket and the skeleton
Bar, the spacing shim is located at the periphery of the mounting hole, and the sealing strip is attached at the one side of the mounting bracket and is provided with and keeps away
Open the bit-avoiding slot of the spacing shim.
Specifically, the both sides of each mounting hole are provided with a pair of spacing holes, there are the spacing shim two to be used for inserting institute
State the convex pin of spacing hole.
Specifically, the screw is square head screw, the skeleton is provided with the chute slided for screw head.
Specifically, the nut is cover type nut.
Specifically, the sealing strip material selects EPDM.
Using above-mentioned technical proposal, the beneficial effect of technical solutions of the utility model is：
1st, the utility model adopts the mode being screwed and FFU cabinets is fixed on skeleton, and sealing uses special construction
Spacing shim and sealing strip, both facilitated installation, and also reached more excellent sealing effectiveness.
2nd, convex pin can allow spacing shim to be fixed on the determination position of mounting bracket, it is ensured that it realizes thickness limitation function, also prevents
Only it deviates in installation process.
3rd, square head screw can be slided along skeleton, thus can neatly be found the position of mounting hole accurately, be improved installation
Efficiency.
4th, acorn nut better appearance, and open dust fall can be prevented.
5th, EPDM sealing strips are relatively good to the tolerance of environment, can there is preferably sealing service life.

Embodiment
The utility model is described in further detail with reference to specific embodiment.
As shown in Figures 1 to 6, a kind of FFU mounting structures of the present utility model, including located at the mounting bracket of the surrounding of cabinet 1
2, mounting bracket 2 is provided with some mounting holes 21, and mounting bracket 2 is fixed to skeleton 3 by the screw 6 and nut 7 through mounting hole 21
On, some rigid spacing shims 4 and flexible sealing strip 5 are clamped between mounting bracket 2 and skeleton 3, spacing shim 4 is located at peace
The periphery in hole 21 is filled, sealing strip 5 is attached at the one side of mounting bracket 2 and provided with the bit-avoiding slot 51 for avoiding spacing shim 4.Cabinet 1 is
It is placed on by the frame of mounting bracket 2 of surrounding on skeleton 3, and mounting bracket 2 is fixed with skeleton 3 by screw 6 and nut 7, so
Installation can be put using installation and side is kept flat among actual assembled, more freely facilitated compared to originally single mode.Spacing pad
Piece 4 is non-overlapping with sealing strip 5, and spacing shim 4 limits the spacing between mounting bracket 2 and the upper surface of skeleton 3, and this
Spacing determines the decrement of sealing strip 5.The thickness of each spacing shim 4 is equal, so when nut 7 is locked
Wait, all decrements of fixed point sealing strip 5 are identical, also avoid in the case of spacing shim 4 is not present, sealing strip 5 has
Elasticity causes the problem of decrement is difficult to consistent, it is ensured that sealed uniformity and reliability.
As shown in Fig. 2, Fig. 3 and Fig. 5, the both sides of each mounting hole 21 are provided with a pair of spacing holes 22, and spacing shim 4 has two
The individual convex pin 41 for being used for inserting spacing hole 22.When actual installation, spacing shim 4 is placed on mounting bracket 2 by convex pin 41,
Human hand avoids the need for reaching between mounting bracket 2 and skeleton 3 goes adjustment position again, prevents its process tightened in screw 6 and nut 7
It is middle to deviate.Because spacing shim 4 is sandwiched between mounting bracket 2 and skeleton 3, tighten after nut 7, convex pin 41 can allow
Spacing shim 4 is fixed on the determination position of mounting bracket 2, also just spacing shim 4 can be maintained to be located at the state on the periphery of mounting hole 21, protected
Demonstrate,prove it and realize thickness limitation function.As long as spacing hole 22 plays the function of allowing spacing shim 4 to position, number and position can be with
Adjust as required.
As shown in figure 4, screw 6 is square head screw, skeleton 3 is provided with the chute 31 slided for the head of screw 6.Skeleton 3 is
A kind of section bar of strip, chute 31 is extended along skeleton 3, and the head of screw 6 enters chute 31 later just can easy slide.
After casing 1, which is installed, to be started, as long as screw 6 goes to be directed at the position of mounting hole 21 to be fixed, through it, then screwed with nut 7
.In the above process, workman only needs to a hand can just operate through the framework of skeleton 3, need not when keeping flat installation
Further climb, installation effectiveness is high.
As shown in figure 4, nut 7 is cover type nut.Acorn nut better appearance, and open dust fall can be prevented.
As shown in Fig. 3, Fig. 4 and Fig. 6, the material selection EPDM (ethylene propylene diene rubber) of sealing strip 5.EPDM principal polymeric
Chain is fully saturated, and this characteristic allows it to resist heat, light, oxygen, especially ozone.EPDM molecules are nonpolarity again
, resistant to polar solvent and chemicals, water absorption rate is low, with good insulation characterisitic.So EPDM sealing strips 5 are to ring
The tolerance in border is relatively good, can have preferably sealing service life, it is ensured that effective sealing between mounting bracket 2 and skeleton 3.
Above-described is only some embodiments of the present utility model.For the person of ordinary skill of the art,
On the premise of the utility model creation design is not departed from, various modifications and improvements can be made, these belong to this practicality
New protection domain.
