As shown in figures 1-6, the utility model provides a kind of filter flange installation structure, including ring flange 3 and solid
Determine frame 4；
Locating rod 3-2 is provided on the ring flange 3；
The locating slot 4-1, the locating rod 3-2 that side opening is provided on the fixed frame 4 can be in the locating slots
Sliding in 4-1；
It is provided with clamping portion 4-2 on the cell wall of the locating slot 4-1, the locating slot 4-1 slot bottoms can be will slide into
The locating rod 3-2 is blocked.
In the present embodiment, filter flange installation structure includes 4 two parts of ring flange 3 and fixed frame, wherein ring flange
3 are fixedly connected with the filter core of filter, and fixed frame 4 is fixedly installed on the filter, passes through the fixation of ring flange 3 and fixed frame 4
Filter core is fixedly installed on the filter to realize for connection.
In the present embodiment, it is provided with locating rod 3-2 on ring flange 3, locating slot 4-1, locating rod are provided on fixed frame 4
3-2 is by being rotatably inserted into locating slot 4-1, and by the clamping portion 4-2 on the cell wall of locating slot 4-1 by locating rod 3-2 cards
In locating slot 4-1, makes it that can not be skidded off out of locating slot 4-1, ensure that the stability of ring flange 3, avoid due to shaking
It moves and filter core is made to fall off from filter.
Preferred embodiment is, as shown in Figure 3 and Figure 4, the side wall of the locating slot 4-1 is arc along its depth direction
Structure；
The top of the arcuate structure is the clamping portion 4-2.
In the present embodiment, the cross section of the side wall of locating slot 4-1 is arc, and the arc top of arc is clamping portion 4-2, i.e.,
When locating rod 3-2 slides into slot bottom by locating slot 4-1, need by arc top.
When rotating ring flange 3, locating rod 3-2 follows ring flange 3 to rotate, since ring flange 3 cannot move in the vertical direction
It is dynamic, and locating rod 3-2 needs firmly to twist ring flange 3 at this time by needing to change its upper and lower position when arc top so that positioning
Bar 3-2 stress, bend deformation, and when entering the slot bottom of locating slot 4-1, deformation restores；At this point, locating rod 3-2 want from
Be detached from locating slot 4-1, need using larger dynamics reversion ring flange 3, and during use, ring flange 3 only by
Ring flange 3 is avoided to be detached from from fixed frame 4 to realize the fixation to ring flange 3 without torsion to vibration force.
In the present embodiment, arcuate structure is concentric arc.
It should be pointed out that arcuate structure can be the arc of decentraction, i.e., the arc intersection of two or more decentractions,
Using its intersection position as clamping portion 4-2 so that the stress of the clamping portion both sides 4-2 is different, and side radian is larger, side radian compared with
Small, so that side is relatively easy to slip over clamping portion 4-2, the other side is more not easy to slip over clamping portion 4-2, can be more effective

Preferred embodiment is, as shown in figure 5, the side wall of the locating slot 4-1 is meander line structure along its depth direction；
The vertex of the meander line structure is the clamping portion 4-2.
In the present embodiment, the cross section of the side wall of locating slot 4-1 is broken line, and the top of broken line is clamping portion 4-2, i.e.,
When locating rod 3-2 slides into slot bottom by locating slot 4-1, need by broken line top.
It is identical with previous embodiment, when rotating ring flange 3, by the side wall of locating slot 4-1 to locating rod 3-2 or more
The power of bending so that locating rod 3-2 can be passed in and out out of locating slot 4-1.And in operation process, ring flange 3 is only shaken
Power avoids ring flange 3 from being detached from from fixed frame 4 without torsion to realize the fixation to ring flange 3.
Similarly, in the present embodiment, the angle of broken line can be identical, can also be different, i.e. side wall broken line and water
Square to angle differ so that the stress of the clamping portion both sides 4-2 is different, and side angle is larger, and side angle is smaller, in turn
So that side is relatively easy to slip over clamping portion 4-2, the other side is more not easy to slip over clamping portion 4-2, and it is fixed more effectively to avoid
Position bar 3-2 is skidded off out of locating slot 4-1.
It should be pointed out that in the present embodiment, the cross section of the side wall of locating slot 4-1 is meander line structure, above-mentioned implementation
In example, the cross section of the side wall of locating slot 4-1 is arcuate structure, but it is not limited solely to above two structure, can be with
It is that there is other kinds of structure, that is to say, that as long as clamping portion 4-2, energy can be arranged in it on the side wall of locating slot 4-1
Enough slot bottoms that locating rod 3-2 is sticked into locating slot 4-1 so that locating rod 3-2 will not be taken off due to vibration out of locating slot 4-1
From.
Preferred embodiment is, as shown in fig. 6, the side wall of the locating slot 4-1 is wave structure along its depth direction；
Each vertex of the wave structure is clamping portion 4-2.
In the present embodiment, the cross section for the side wall that locating slot 4-1 is is waveform, that is to say, that it can constitute more
A clamping portion 4-2, and then the fixed position of ring flange 3 can be adjusted so that it more closes the turned position of ring flange 3
It is suitable.
In the present embodiment, wave structure can have camber line composition, can also be to have broken line to constitute, can also be
Existing camber line has broken line again, that is to say, that as long as it can form multiple clamping portion 4-2.
Preferred embodiment is that two side opposite the locating slot 4-1 is arranged in parallel.
In the present embodiment, the opposite two side walls of locating slot 4-1 are to be arranged in parallel, and such set-up mode was both beautiful,
It is again practical.
It should be pointed out that in the present embodiment, two side walls opposite locating slot 4-1 are arranged in parallel, but it is not only
It is confined to be arranged in parallel, can also be that a side wall is plane, and clamping portion 4-2 is set on another side wall, as long as
Clamping portion 4-2 can be set on side wall, the fixation to ring flange 3 is realized by clamping portion 4-2.
Preferred embodiment is that fixed part 4-3 is provided on the fixed frame 4, for carrying out the fixed frame 4
It is fixed.
The needs of fixed frame 4 are fixed, and to ensure that locating rod 3-2 will not be detached from out of locating slot 4-1, are also further ensured that
The stability of ring flange 3.
In the present embodiment, the fixed part 4-3 of fixed frame 4 is one piece of raised square, can be clamped with other parts
It is fixed together.
It should be pointed out that fixed part 4-3 can be the square of protrusion, it can also be other structures, such as can be spiral shell
The fit structure etc. of bolt and threaded hole, that is to say, that as long as it can fix fixed frame 4.
Preferred embodiment is that the side of the ring flange 3 is provided with twisting portion 3-1, can twist the ring flange 3
It is rotated.
In the present embodiment, twisting portion 3-1 is provided on ring flange 3, using twisting portion 3-1 can drive ring flange 3 into
Row rotation, and then ring flange 3 is fixed.
Preferred embodiment is that the twisting portion 3-1 is two, is arranged with the axisymmetrical of the ring flange 3.
In the present embodiment, twisting portion 3-1 is the twisting ear of two protrusions, and the twisting ear of two protrusions is oppositely arranged, just
In carrying out twisting operation to ring flange 3.
It should be pointed out that in the present embodiment, twisting portion 3-1 is two, but it is not limited solely to two, may be used also
To be three, even more, ring flange 3 is twisted as long as can facilitate.
It may also be noted that in the present embodiment, twisting portion 3-1 is the twisting ear of protrusion, but it is not limited solely to
Raised structures can also be groove, i.e., it can be two grooves being oppositely arranged, and pass through the similar means pair such as a word spiral shell knife
It is twisted.
