Abstract
The utility model relates to the field of electrical equipment, in particular to a novel industrial exhaust fan. The novel industrial exhaust fan comprises a motor and blades. A plurality of supports extend to the rear center of a frame body from the periphery of the frame body and then are connected with a motor rear shell. The motor is fixedly arranged on the motor rear shell, and the blades are fixedly arranged on the axis of the motor. A plurality of peripheral reverse opening stretching rings are arranged at the opening end of the motor rear shell. The externally tangent positions of the peripheral reverse opening stretching rings are provided with groove bayonets. A convex reinforcing groove is formed in the middle of each groove bayonet. The novel industrial exhaust fan is firm in structure and capable of bearing impacting force caused by large power.
Description
Technical field
The utility model relates to the electrical equipment field, specifically provides a kind of infant industry ventilating fan.
Background technique
The industrial exhaust gas fan is widely used in the factory building workshop, waits the production place, with respect to the family expenses ventilating fan, has high-power, high-revolving characteristics.Existing industrial exhaust gas fan, the motor of back cover all are to rely on four supports to be connected and fixed work, and not anti-twist and warping arrange.So during machine operation, the centrifugal force that produces causes the easy crooked modification of support, make motor uneven and cause the damage of ventilating fan.In addition, existing industrial exhaust gas fan motor back cover location and installation inconvenience, loosening with the support ease of connection, and also not attractive in appearance after installing yet.
Summary of the invention
At problems of the prior art, the purpose of this utility model is to provide a kind of infant industry ventilating fan, has firm supporting structure, and it is highly stable that motor is installed the back, can bear the high-power big centrifugal force that causes.
To achieve these goals, the utility model provides following technological scheme:
A kind of infant industry ventilating fan of the utility model comprises motor and blade.Several supports are connected toward rear center's extension and with the motor back cover from the periphery of framework.Motor is fixed on the motor back cover.Vanes fixed is on the axle center of motor.The opening end of described motor back cover is provided with several peripheral anti-mouthful of circles that stretches.The circumscribed position of the peripheral anti-mouthful of circle that stretches is provided with the groove bayonet socket.The centre of groove bayonet socket arranges the reinforcement groove of an evagination.
Preferably, the anti-mouthful of circle that stretches in described periphery is provided with circular hole, is connected and fixed by bolt and described support.
Preferably, the middle part of described support is provided with stiffening rib longitudinally.Stiffening rib is stamping forming groove.
The beneficial effects of the utility model are:
1, the opening end of motor back cover is provided with the peripheral anti-mouthful of circle that stretches, and makes to have enough rigidity between the housing of groove bayonet socket and motor back cover, connects firmly.The groove bayonet socket is formed by direct stretching of the sheet metal of motor back cover housing, does not have the linkage structures of becoming flexible easily in the use such as bolt.
2, the edge of groove bayonet socket is stuck on the support, and is easy for installation, and limited between groove bayonet socket and the support freedom of movement along the connecting bolt circumferencial direction.Therefore, between groove bayonet socket and the support be connected firm.
3, the groove bayonet socket is provided with the reinforcement groove of evagination, plays the effect of stiffening rib, has increased the rigidity of groove bayonet socket, can bear higher impact force.
4, support is provided with stiffening rib, and structure is more firm.
Description of drawings
Fig. 1 is for being used for the structural representation of explanation the utility model industrial exhaust gas fan;
Fig. 2 is the structural representation for the motor back cover that the utility model industrial exhaust gas fan is described;
Fig. 3 is the A-A generalized section of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment technical solutions of the utility model are further specified, are not considered as the restriction to the utility model protection domain:
As Fig. 1, Fig. 2, shown in Figure 3, a kind of infant industry ventilating fan of the utility model comprises motor and blade 03.Several supports 04 are connected toward rear center's extension and with motor back cover 01 from the periphery of framework 02.Motor is fixed on the motor back cover.Vanes fixed is on the axle center of motor.The opening end of described motor back cover is provided with several peripheral anti-mouthful of circles 11 that stretches.The circumscribed position of the peripheral anti-mouthful of circle that stretches is provided with groove bayonet socket 14.The centre of groove bayonet socket arranges the reinforcement groove 13 of an evagination.
The peripheral anti-mouthful of circle 11 that stretches is provided with circular hole 12, is connected and fixed by bolt and described support 04.The middle part of support 04 is provided with stiffening rib 41 longitudinally.Stiffening rib 41 is stamping forming groove.
During use, groove bayonet socket 14 is stuck on the support 04, and it is fixing to pass circular hole 12 with bolt.
