Abstract

Disclosed is a ventilating fan, comprising a ventilating fan body and a flange for fixing the ventilating fan body on the ceiling frame. The flange is in shape of square and fixedly connected to the installing frame of the ventilating fan body; A plurality of selectable or movable positioning devices for positioning the fixed positioning flange on the ceiling frame are arranged on the surface of the flange; A screw hole is formed on the surface of the flange, through which the screw installs the fixed positioning flange on the ceiling frame. When the fixed positioning flange of this structure is used to install the ventilating fan to the ceiling frame, the ventilating fan can be installed in the installing holes of different dimensions of ceiling frames by adopting or moving the positioning devices on the surface of the flange, thus solving the difficulty results from the ventilating fan not matching with the dimension of the ceiling frame when installing the ventilating fan.

Description

Ventilation fan

Technical field

The utility model relates to a kind of ventilation fan.

Background technique

Ventilation fan is a kind of room ventilation air regenerating device of a large amount of uses, and when ceiling board was installed ventilation fan, wooden frame was built by general elder generation on ceiling board, reserve the hole that ventilation fan is installed on the framework.But in different regions, the size dimension in the yoke hole that ceiling board yoke construction is reserved is often inequality, and just the installation behind the various places brings difficulty to a kind of ventilation fan production marketing for this.In addition, the user is when the ventilation fan that more renews, and the installation dimension of the ventilation fan of new old model also has difference, and this also can cause to change to install needs the trouble of construction again.

Chinese patent utility model patent 96217391.6 provides a kind of ventilation fan.It stretches out around comprising housing, motor, blade, catch, case panel, forms the square or rectangle mounting plate that the big I of planar is carried; One side of this external mounting plate, both sides, three limits or four limits are provided with " H " type filler rod.This patent is by cutting mounting plate, being installed in the mounting point by " H " type filler rod.But the restricted application of this patent, the ventilation fan that is installed on the ceiling for needs is unconformable.

The model utility content

Task of the present utility model provides a kind of ventilation fan, can adapt to different installation dimensions.

Task of the present utility model is finished by the following technical programs: design a kind of ventilation fan, comprise that a ventilation fan body and is used for the ventilation fan body is fixed on the ceiling frames upper flange, this flange is square, is fixedly connected on the ventilation fan body installing frame face; On flanged surface, also have a plurality of the selection or the positioning device of mobile position, be used for locating flange is positioned at ceiling frames; Be formed with screw hole on the flanged surface, screw passes this hole locating flange is installed on the ceiling frames.

Described ventilation fan is provided with positioning device at four frame faces of flanged surface.

Described ventilation fan, wherein screw hole is and the vertically disposed strip hole in the limit of flanged surface.

When using the locating flange of this structure that ventilation fan is installed to ceiling frames, can by select for use or the rotary flange face on these form the positioning device of projections, the installation dimension of conversion ventilation fan stationary positioned flange can be installed in the frame hole of the different size that ceiling frames reserves ventilation fan.

Realize the function of above-mentioned positioning device, the utility model provides two kinds of schemes,

A kind ofly be:

Be provided with on flanged surface one can form the positioning device of projection or the integrated positioning device of being made up of one group of described otch of several spaces through extruding.The single independent positioning device that is provided with can be arranged on any position on the flanged surface, and preferably is arranged on (generally being made up of 2-4 or above positioning device) position, angle of flanged surface in the mode that is the oblique line arrangement by one group of integrated positioning device.This positioning device that forms projection is preferably otch.Preferable otch be shaped as flute profile or V-type, U type,

Type, The type otch.

The center portion of these otch is pressed to vertical, just form the position block of projection with flanged surface.For the position block structure of combination otch, when ventilation fan is installed, can form position block according to the corresponding otch of the size Selection of mounting hole.

Another kind is:

Employing is at positioning runner that forms on the flanged surface and the angle bar that slides in this positioning runner, by moving and fixing angle bar, adjusts the position, and with the stationary positioned flange, promptly ventilation fan is positioned on the fixed border in its moving range.

The positioning device of this form because this angle bar can move in positioning runner flexibly, makes this stationary positioned flange can mate various mounting hole size within the specific limits better.Described positioning runner is the oblique position, angle that is arranged on flanged surface preferably.

By stationary positioned flange of the present utility model ventilation fan is installed, can by select for use or the rotary flange face on positioning device go to be close to or near the frame hole of ceiling frames, form the location, thereby make ventilation fan can be suitable in having the frame hole, sky of different size, installing, thereby solved when ventilation fan is installed the difficulty that does not match and cause owing to ventilation fan and its installation ceiling frames size.
