Description
Technical field
The utility model relates to motor accessories field, especially a kind of buckle-type cross flow fan side cover.
Background technique
Cross flow fan includes motor and wind wheel, and the shaft of motor is fixedly connected with wind wheel, wherein is set between shaft and wind wheel
There is a side cover baffle, preventing foreign matter from entering influences blower work.The mistake of machine shaft and wind wheel is fixed in blower side cover
Cheng Zhong, traditional design are to allow side cover to be fixed on blower side by way of screwing, but in the production of blower and make
It is low with the fixed efficiency that in the process, screws, and when have because material shortage due to be fixed using the screw of different model or by
Power is uneven, is easy to cause blower side cover to fix not just, blower generates larger noise.
Utility model content
The purpose of the utility model is to overcome existing cross flow fan, that there are side cover fixed efficiencies is low, the fixed difficulty of side cover is big
And side cover generates the defect of abrasion because of deformation and shaft.
To achieve the above object, the utility model provides a kind of buckle-type cross flow fan side cover, including side cover plate and along side
The side cover flange that side edge thereof is bent to form to side, in which:
The side cover plate is equipped with shaft mounting hole and a pair of of motor installing hole, and the shaft mounting hole is opened in side cover plate
Middle part, the motor installing hole are symmetricly set on the both sides of the edge of side cover plate, and side cover plate prolongs along motor installing hole lateral direction
It stretches to form local protrusion, prominent two sides connect to form stress release portion with side cover flange, and the side cover flange is equipped with several groups
Holding section that is prominent along side cover flange end and bending extension outward.
Preferably, holding section includes engaging foot and clamping block, the arc-shaped convex of clamping block.
Preferably, side cover plate is additionally provided at least a pair of spare motor installing hole, spare motor installing hole to shaft is installed
Pitch-row of the pitch-row in hole not equal to motor installing hole to shaft mounting hole.
The utility model has the beneficial effects that improving the structure of existing cross flow fan motor connection side cover, pass through inlaid type
Fixed side cover shortens the time and avoids side cover deformation；Setting strain relief avoids side cover from generating because of stress and deformation and shaft
Abrasion.
Detailed description of the invention

Specific embodiment
To be more clear the objectives, technical solutions, and advantages of the embodiments of the present invention, below in conjunction with embodiment and
Attached drawing, the utility model will be further described.
The utility model provides a kind of buckle-type cross flow fan side cover.
It please refers to as shown in Figure 1-3, include side cover plate 1 and side cover flange from 1 edge of side cover plate to side that be bent to form along
2, in which:
Side cover plate 1 is equipped with shaft mounting hole 3 and a pair of of motor installing hole 4, and shaft mounting hole 3 is opened in side cover plate 1
Portion, gives the channel that machine shaft is connect with blower wind wheel, and motor installing hole 4 is symmetricly set on the both sides of the edge of side cover plate 1, and two
A installation axle clicked mounting hole 4 and connect motor.Side cover plate 1 extends to form local protrusion along 4 lateral direction of motor installing hole,
Prominent two sides connect to form stress release portion 5 with side cover flange 2, for improving side cover edge stress and deformation, reinforce motor connection
The stability at position, side cover flange 2 are equipped with the holding section 6 that several groups protrude along 2 end of side cover flange and bend extension outward.
In existing technical solution, cross flow fan side cover is fixed on cross flow fan by screwing, screw model and use
Power unevenly will lead to side cover, and there are small deviations, and with the use of blower, shaft is contacted with side cover generates noise, seriously
When shorten fan life；In the technical solution of the utility model, cross flow fan side cover is mounted on by way of being fixed to be passed through
On flow fan, blower side is equipped with engaging slot compatible with holding section 6, can be reduced the production time, and side cover is avoided to exist
Minor shifts；Motor installing hole 4 nearby stress and deformation it is more serious, the utility model be equipped with stress release portion 5, reduce side cover by
Power deformation avoids making because of side cover deformation generating abrasion between side cover and shaft.
As a preferred technical solution, as shown in figure 3, in order to more stably fix side cover, holding section 6 includes engaging foot 6-
1 and clamping block 6-2, engaging foot 6-1 protrudes from side cover flange 2, and for extending to the engaging slot on blower, clamping block 6-2 is towards side
The arc-shaped convex in 1 direction of cover board has more stable fixed effect, and the self structure of clamping block 6-2 is more firm.
As a preferred technical solution, in order to be adapted to the different motor of installation shaft size, at least one is opened up on side cover plate 1
To spare motor installing hole 7, the pitch-row of spare motor installing hole 7 to shaft mounting hole 3 is pacified not equal to motor installing hole 4 to shaft
Fill the pitch-row in hole 3.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, although referring to before
Embodiment is stated the utility model is described in detail, it for those skilled in the art, still can be to preceding
Technical solution documented by each embodiment is stated to modify or equivalent replacement of some of the technical features.It is all this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
