Abstract

The utility model relates to a motor shell for a large-sized exhausting fan, which mainly comprises a shell, a motor and a plurality of brackets, wherein, one side of the shell is provided with an air exhausting pipe in an extending mode, and the other side of the shell is provided with a proper-sized air inlet in an extending mode. The inner periphery surface of the air inlet is symmetrically perforated with a plurality of through holes for fixedly locking by the bracket with through holes, the center of one side end surface of the motor is convexly provided with a shaft center with a fan blade, a plurality of guiding sloping grooves are convexly arranged on an outer frame in an annular mode and are near a plurality of guiding traverse grooves, and a T-shaped screw is arranged in the guiding sloping grooves and the guiding cross grooves for pivoting and positioning and is mutually locked with the through hole of the other end of the bracket. By using the structure, the brackets can be surely adjusted to be positioned on the gravity centers of the motor and the fan blade according to the size of the motor, the size of different fan blades and materials, and the best supporting state can be obtained. When the motor and the fan blade run, the generated swing can be reduced, the good stability can be achieved, and meanwhile, the service life can be extended, the generated noise can be avoided, the fan blade can be normally operated, and the effect that the air quantity can not be affected can be achieved.

Description

The motor case of large-scale ventilating fan

Technical field

The utility model refers to a kind of motor case of ventilating fan especially relevant for a kind of structure of ventilating fan.

Technical background

The motor case of the large-scale ventilating fan of generally commonly seeing at present, be for practising the three-dimensional exploded view of formula as shown in Figure 1, it mainly comprises: a housing 10, one motor 20 and some supports 30, its middle shell 10, and the extension of a side of housing 10 is provided with a circular row airduct 11, opposite side then extends the intake grill 12 that a suitable generous shape is set, inner peripheral edge surfaces symmetry in intake grill 12 provides some perforation 13, one side direction outer ring-like of motor 20 is convexly equipped with the fixed block 21 of some tool perforation 211, be convexly equipped with an axle center 23 in the center sheathed for a fan blade 24, support 30 is to establish to be suitable length, provides a perforation 31 in two side ends.

During its desire combination, be for practising the user mode schematic representation of formula as shown in Figure 2, be earlier the perforation 31 of support 30 1 ends to be locked one by one fixed block 21 perforation 211 of tying in motor 20, after again the motor 20 of sheathed fan blade 24 being inserted by the intake grill 12 of housing 10 subsequently, make the perforation 31 of support 30 opposite sides involutory with perforation 13, give screw lock knot more one by one, then can finish assembling;

Habit formula structure as implied above, it still has following disappearance: (one) refers to that especially this support 30 is sides that are fixed in motor 20, not only can't do suitable adjustment according to motor 20 and fan blade 24 population size and material, more can't effectively support the center of gravity of motor 20 and fan blade 24, cause support effect not good: (two) refer to its motor 20 especially in case start when driving fan blade 24 runnings simultaneously, then can can't effectively support the center of gravity of motor 20 and fan blade 24 because of support 30, and make this large-scale electric fan rocking and produce vibrations with motor 20 and fan blade 24, and then reduce working life, easilier produce bigger noise because of vibrations, when fan blade 24 was with the work vibrations simultaneously, it was influenced then air quantity to be diminished; (3) refer to that especially its support 30 only is a side end face of being fixed in motor 20, and the overall weight rotating hanging that makes motor 20 is in opposite side, when in case the vibrations of motor 20 and fan blade 24 are big, then can make spiral shell be located at the screw phenomenon that loosening spiral shell is separated because of vibrations produce of support 30, and the drawback that causes motor 20 to get loose and drop together with fan blade 24.

This creator is because the disappearance of above-mentioned habit formula structure, is think and the idea of creation, satisfies with for many years experience and designed, and through inquiring into and study sampling test in many ways, and repeatedly revises improvement, is to release the utility model.

Summary of the invention

Main purpose of the present utility model, be that a kind of motor case structure of large-scale ventilating fan is being provided, especially refer to that the T shape screw in its motor guiding translot (or guiding skewed slot) is to lock with support, so can do outside the suitable adjustment with size, the material of different fan blades according to motor, and can effectively make support be positioned at the center of gravity of motor and fan blade, reach best holding state.

Secondary objective of the present utility model, be that a kind of motor case structure of large-scale ventilating fan is being provided, especially refer to that its support is the center of gravity that is positioned at motor and fan blade, so when motor drives the fan blade running, can effectively reduce motor and fan blade in rocking of producing of when running, it is good to reach steadiness, and can increase the service life and avoid producing noise, and fan blade can make its air quantity unaffected in running well down.

Above-mentioned purpose is achieved in that

A kind of motor case of large-scale ventilating fan, it mainly comprises: a housing, a motor and some supports, the one side extension of this housing is provided with an exhaust duct, opposite side then extends a suitable big intake grill is set, inner peripheral edge surfaces symmetry in intake grill provides some perforation, this perforation be with support on the set perforation of fixedly support body locking, the center, a side end face of motor is convexly equipped with an axle center and a fan blade is sheathed, it is characterized in that

It is adjacent with some guiding translots that the shell ring-type of motor is convexly equipped with some guiding skewed slots, this guiding skewed slot and guiding translot are to wear the location for a T shape screw hub setting, and this T shape screw is to cooperatively interact with set location piece of described support and perforation that lock is established and together move for motor and fan blade to adjust.

The guiding skewed slot of this motor and guiding translot are can establish respectively to be shape.

The head of this T shape screw is can establish to be bigger cubic shape just with the guiding skewed slot and guide translot and fasten mutually.

Compare with located by prior art, good effect of the present utility model is:

Because the motor case structure of the ventilating fan that the utility model provides, T shape screw in its motor guiding translot (or guiding skewed slot) is to lock with support, so can do suitable adjustment according to size, the material of motor and fan blade, effectively to make support be positioned at the center of gravity of motor and fan blade, reach best holding state, and can effectively reduce rocking that motor and fan blade produce when running, it is good to reach steadiness, increase the service life simultaneously and avoid producing noise, and fan blade can be run well, make its air quantity unaffected.
