Abstract
The utility model relates to a cross-flow fan which is composed of a motor (1), a volute (2), an impeller (3), a first fixing part (4), and a second fixing part (5). The first fixing part (4) is H-shaped. Screw holes are formed in two ends of an upper across arm of the first fixing part and in two ends of a lower cross arm of the first fixing part. The screw hole in one end corresponds to a screw hole formed in one lateral side of the volute (2) and is fixedly connected with the volute (2) through a fist screw (6). The screw hole in the other end corresponds to screw holes formed in the motor (1) and in the second fixing part (5) and is fixedly connected with the motor (1) and the second fixing part (5) through second screws (7). A gasket (8) is placed on the inner side of the first screw (6). The gasket (8) is thick enough to enable a gap (9) in a lateral plate of the volute (2) to be filled. According to the cross-flow fan, the motor is prevented from loosing along with the working vibration of the fan, and the fan is enabled to work stably for a long time.
Description
Technical field
The utility model relates to a kind of structure of cross flow fan.
Background technique
Cross flow fan generally all comprises the primary clusterings such as impeller, spiral case and motor, and wherein, impeller is placed on by bearing support on the biside plate of spiral case, and motor is connected with impeller by coupling shaft, is fixedly connected with by auxiliary fixing member between spiral case and motor.Existing cross flow fan often only adopts the mode of screw fastening when motor and auxiliary fixing member are fixed on spiral case side plate.The problem that this structure exists is: fastening screw trip bolt is easily loosening afterwards in the vibrations that produced by the blower fan running, causes motor loosening, thereby affects the normal operation of blower fan.
The model utility content
The utility model discloses a kind of cross flow fan, be intended to solve existing existing the problems referred to above of cross flow fan.
The technical solution of the utility model is as follows:
A kind of cross flow fan comprises motor, spiral case and impeller, it is characterized in that, this cross flow fan also comprises fixed block one and fixed block two; Described fixed block one is I-shaped, the two ends of its upper and lower transverse arm all have screw hole, the screw hole of opening on one side plate of the screw hole of one end and spiral case is corresponding, and be fixedly connected with spiral case by screw one, the screw hole of opening on the screw hole of its other end and motor, fixed block two is corresponding, and is fixedly connected with fixed block two with motor by screw two.
Above-mentioned a kind of cross flow fan is characterized in that the inboard of described screw one is placed with pad, and the thickness of pad is enough to make the space on spiral case side plate to be filled, and then the stub end end face of screw one is propped up by the side plate of spiral case.
The beneficial effects of the utility model are: by add pad between screw one and spiral case side plate, can fill up the space on spiral case side plate, when making motor tightly be fixed on spiral case side plate, the major part exterior edge face of screw one is withstood by the spiral case side plate wall, cause the loosening situation of motor to occur after screw one from becoming flexible with the vibrations of blower fan with regard to having prevented like this.

Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
See figures.1.and.2:
A kind of cross flow fan comprises motor 1, spiral case 2 and impeller 3, also comprises fixed block 1 and fixed block 25; Fixed block 1 is I-shaped, the two ends of its upper and lower transverse arm all have screw hole, the screw hole of opening on one side plate of the screw hole of one end and spiral case 2 is corresponding, and be fixedly connected with spiral case 2 by screw 1, the screw hole of opening on the screw hole of its other end and motor 1, fixed block 25 is corresponding, and is fixedly connected with fixed block 25 with motor 1 by screw 27.
The inboard of screw 1 is placed with pad 8, and the thickness of pad 8 is enough to make the space 9 on spiral case 2 side plates to be filled, and then the stub end end face of screw 1 is propped up by the side plate of spiral case 2.
Under the effect of pad 8, the stub end end face of screw 1 and the side plate of spiral case 2 tightly prop up each other, the vibrations even blower fan works long hours, and screw 1 can not become flexible yet, and the motor 1 that is fastened on spiral case 2 by screw 1 just can not become flexible yet.
Claims (2)
1. a cross flow fan, comprise motor (1), spiral case (2) and impeller (3), it is characterized in that, this cross flow fan also comprises fixed block one (4) and fixed block two (5); Fixed block one (4) is I-shaped, the two ends of its upper and lower transverse arm all have screw hole, the screw hole of opening on one side plate of the screw hole of one end and spiral case (2) is corresponding, and be fixedly connected with spiral case (2) by screw one (6), the screw hole of opening on the screw hole of its other end and motor (1), fixed block two (5) is corresponding, and is fixedly connected with fixed block two (5) with motor (1) by screw two (7).
2. a kind of cross flow fan according to claim 1, it is characterized in that, the inboard of screw one (6) is placed with pad (8), the thickness of pad (8) is enough to make the space (9) on spiral case (2) side plate to be filled, and then the stub end end face of screw one (6) is propped up by the side plate of spiral case (2).
