Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment one: a kind of mounting structure of air intake cover used for rail vehicle, referring to Fig.1, including air inlet in a rectangular parallelepiped shape
Cover 2 and the cyclic annular installation frame 1 being mounted in vehicle side wall, and the cross section of installation frame 1 is arranged in rectangle, installation frame
1 is located at the air inlet of vehicle.Installation frame 1 is bolted to connection in vehicle side wall, is bolted as relatively more normal
The fixed form of rule realizes being detachably connected for installation frame 1, the replacement convenient for the later period for installation frame 1.Meanwhile into
Two opposite sides of fan housing 2 are fixedly installed with the mounting blocks 3 of rectangular-shape, and mounting blocks 3 are towards the side of installation frame 1
With the side flush in the same direction of air intake cover 2.
Referring to Fig. 3 and Fig. 4, installation frame 1 is welded with snap-gauge 4, mounting blocks 3 away from the surface of vehicle side wall in the horizontal direction
Surface offer the card slot 5 matched with snap-gauge 4, and snap-gauge 4 and card slot 5 are L-shaped.By 3 phase of mounting blocks on air intake cover 2
Pair the position for being placed in snap-gauge 4 and card slot 5 and being clamped, after snap-gauge 4 and the sufficiently clamping of card slot 5, air intake cover 2 is in snap-gauge 4 and card slot 5
It is fixed under clamping effect and self gravitation effect, convenient for air intake cover 2 is connected on installation frame 1.
Meanwhile it is equipped between installation frame 1 and mounting blocks 3 for sealed and unlock mounting blocks 3 limit assemblies.Limit
Component includes slippage slot 6, spring 8 and closing piece 7, and the slippage slot 6 is opened in installation frame 1 towards air intake cover in the horizontal direction
2 surface, and slippage slot 6 is located at the surface of snap-gauge 4, the sliding of closing piece 7 is connected in slippage slot 6；Meanwhile the fixed company of spring 8
Be connected between closing piece 7 and the slot bottom of slippage slot 6, when spring 8 descends in the raw, closing piece 7 protrude from slippage slot 6 and with peace
The upper surface for filling block 3 is inconsistent.Closing piece 7 is slided into slippage slot 6, spring 8 is compressed；Snap-gauge 4 and card slot 5 are sufficiently clamped
Afterwards, closing piece 7 skids off slippage slot 6 under the restoring force effect of spring 8, and contradicts with convex block, so that the movement of mounting blocks 3 is limited
System, mounting blocks 3 and installation frame 1 are fixed more firm, to improve the stability after air intake cover 2 is installed；When needing to dismantle
When air intake cover 2, closing piece 7 is slided into slippage slot 6, just can easily remove air intake cover 2.
Referring to Fig. 3 and Fig. 4, closing piece 7 matches towards the direction of 6 slot bottom of slippage slot integrally formed with the notch of slippage slot 6
The block 9 of conjunction, the setting of block 9 make closing piece 7 be not easy to be detached from from the notch of slippage slot 6, reduce closing piece 7 and slippage slot 6 is detached from
And the case where causing mounting blocks 3 and installation frame 1 to be detached from, to further increase the steady of air intake cover 2 and the fixation of installation frame 1
It is qualitative.
Fig. 2 and Fig. 4 are reviewed, the cell wall of 6 side of slippage slot offers through-hole 10, and through-hole 10 is connected with slippage slot 6；Together
When, the interior sliding of through-hole 10 is connected with driving lever 11, and the surface of driving lever 11 is provided with anti-skid chequer (not marking in figure), and driving lever 11 is through logical
The one end in hole 10, driving lever 11 is fixedly connected with block 9, and the other end stretches out in the side of installation frame 1.The setting of driving lever 11 is convenient
Mobile closing piece 7, and then keep the unlock of mounting blocks 3 more convenient.
In addition, the surface of installation frame 1 towards air intake cover 2 is fixedly installed with resilient rubbber cushion 13.Resilient rubbber cushion 13
It is arranged and enhances the compactness that air intake cover 2 is connect with installation frame 1, and then is more firmly mounted air intake cover 2.
Total course of work: when needing to install air intake cover 2, by the mounting blocks 3 on air intake cover 2 it is opposite be placed in snap-gauge 4
The position being clamped with card slot 5, the side of mounting blocks 3 compress closing piece 7, and spring 8 compresses, until the side of mounting blocks 3 and installing frame
The surface of frame 1 is supported and is touched, and mounting blocks 3 are unclamped, and mounting blocks 3 are clamped snap-gauge 4 and card slot 5 sufficiently,
Meanwhile closing piece 7 skids off slippage slot 6 under the restoring force effect of spring 8, and contradicts with convex block, so that the movement of mounting blocks 3 is limited
System, to improve the stability after air intake cover 2 is installed；When needing to dismantle air intake cover 2, driving lever 11 is stirred, so that closing piece 7 is complete
It slides into slippage slot 6 entirely, and then mobile mounting blocks 3, is detached from snap-gauge 4 and card slot 5.
Embodiment two: a kind of mounting structure of air intake cover used for rail vehicle, referring to figure 5 and figure 6, the present embodiment and embodiment
One difference is: limit assembly is different, limit assembly include the one end being fixedly mounted on snap-gauge 4 far from installation frame 1 and
The magnet 12 of 5 slot bottom of card slot being mutually attracted.When installing air intake cover 2, acted on using the mutual actuation of magnet 12, so that snap-gauge
4 connect stronger with card slot 5, and then make air intake cover 2 that loose phenomenon to be less likely to occur, improve the stability of air intake cover 2.When
When needing to dismantle air intake cover 2, applies certain power and the magnet 12 of magnet 12 and 4 end of snap-gauge in card slot 5 is detached from, in turn
Conveniently realize the disassembly of air intake cover 2.
Above-described embodiment is only the explanation to the utility model, is not limitations of the present invention, this field
Technical staff can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but only
It will be in the scope of the claims of the utility model all by the protection of Patent Law.
