Abstract
The utility model relates to the technical field of fans, in particular to a compact type centrifugal fan. The compact type centrifugal fan is provided with an air duct, an impeller and a motor, and the impeller is arranged at the output shaft end of the motor and is arranged in the air duct. The compact type centrifugal fan is characterized in that a supporting device, fixed rods, locating bolts and fastening bolts are arranged, the supporting device is composed of mounting plates, connecting frames and fixed seats, the fixed rods are arranged at the upper end and the lower end of the outer wall of the middle of the motor respectively in the radial direction, threaded holes are formed in the centers of the end portions of the fixed rods, the mounting plates are arranged on the two sides of the motor respectively, the motor penetrates through holes formed in the mounting plates and the threaded holes in the end portions of the fixed rods through the fastening bolts to fix the fixed rods on the mounting plates, two ends of the mounting plates are fixedly and respectively connected with the fixed seats through the connecting frames, and the fixed seats are fixed to the air duct through the locating bolts. The compact type centrifugal fan has the advantages of being compact in structure, easy to manufacture, convenient to mount and dismount, small in vibration, low in cost, safe, reliable and the like.
Description
Technical field
The utility model relates to blower fan technical field, specifically a kind of compact type centrifugal blower.
Background technique
At present, the cooling equipment in the places such as existing subway, airport adopts braking resistor blower fan conventionally, and because structural design is unreasonable, in using process, blower fan very easily produces vibrations, affect the reliability of blower fan, or in order to strengthen rigidity, avoid in running, producing vibrations, increase the reliability of blower fan, conventionally in one end of blower fan, increase the support device of motor, cause blower fan complicated integral structure, dismounting difficulty, causes and makes and cost of overhaul increase.
Summary of the invention
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, the compact type centrifugal blower that provide a kind of compact structure, make simple, easy accessibility, vibrations is little, cost is low, safe and reliable.
The utility model solves the technological scheme that its technical problem adopts:
A kind of compact type centrifugal blower, be provided with air duct, impeller and motor, motor output shaft end is provided with impeller, impeller is located in air duct, it is characterized in that being provided with support device, fixing rod, holding down bolt and clamping bolt, described support device is by mounting plate, link press span and fixed base form, the upper and lower two ends of outer wall, described motor middle part are radially provided with respectively fixing rod, center, fixing rod end is provided with tapped hole, motor both sides are respectively equipped with mounting plate, the hole that motor is provided with through mounting plate through clamping bolt and the tapped hole of fixing rod end are fixed on fixing rod on mounting plate, described mounting plate two ends are fixedly connected with fixed base through link press span respectively, fixed base is fixed on air duct through holding down bolt, so that the center of gravity of motor is located within the scope of the support of mounting plate, avoid in running because crank produces vibrations.
The present invention is owing to adopting said structure, has compact structure, makes simple, easy accessibility, vibrations are little, cost is low, the advantage such as safe and reliable.
accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Reference character: air duct 1, motor 2, fixing rod 3, holding down bolt 4, clamping bolt 5, mounting plate 6, link press span 7, fixed base 8.
Embodiment:
Below in conjunction with accompanying drawing, the present invention is further described:
As shown in drawings, a kind of compact type centrifugal blower, be provided with air duct 1, impeller and motor 2, motor 2 output shaft ends are provided with impeller, impeller is located in air duct 1, motor is located at the intake grill center of air duct 1, it is characterized in that being provided with support device, fixing rod 3, holding down bolt 4 and clamping bolt 5, described support device is by mounting plate 6, link press span 7 and fixed base 8 form, the described motor 2 upper and lower two ends of middle part outer wall are radially provided with respectively fixing rod 3, fixing rod 3 centers, end are provided with tapped hole, motor 2 both sides are respectively equipped with mounting plate 6, the hole that motor 2 is provided with through mounting plate 6 through clamping bolt 5 and the tapped hole of fixing rod 3 ends are fixed on fixing rod 3 on mounting plate 6, described mounting plate 6 two ends are fixedly connected with fixed base 8 through link press span 7 respectively, fixed base 8 is fixed on air duct 1 through holding down bolt 4, so that the center of gravity of motor 2 is located within the scope of the support of mounting plate 6, avoid in running because crank produces vibrations.
The utility model, when operation, due to the center of gravity position of support device support motor 2, has avoided motor 2 operations to produce vibrations.
The present invention is owing to adopting said structure, has compact structure, makes simple, easy accessibility, vibrations are little, cost is low, the advantage such as safe and reliable.
