Embodiment 1

[0026] As shown in Figure 1, the movable positioning flange for installing the ventilating fan in this embodiment is assembled and connected to the four corners of the square frame 4 of the ventilating fan body 3 by two pairs of L-shaped assemblies 1 and 2 to form a movable flange. Each L-shaped assembly and the square frame 4 are riveted with rivets through two sliding grooves 5 that cooperate with each other, and a certain interval is left at the riveting place, so that the riveted L-shaped assembly can be placed in the sliding groove. Carry out relative movement with square frame 4. There are 8 screw hole slots 6 for installation on the movable positioning flange surface, and a cutout is provided at each of the four corners of the movable positioning flange. The positioning block 7 formed by pushing.

Embodiment 2

[0030] As shown in Figure 3, the movable positioning flange used for installing the ventilating fan in this embodiment is composed of a pair of L-shaped assemblies 1 to form an assembly, which can be assembled and connected to two diagonal positions of the square frame of the ventilating fan body to form a movable Flange. Each L-shaped assembly can form a slidable connection with the square frame through four sliding grooves 5 . There are also 4 screw hole slots 6 for installation. A combined slit that can form a positioning stop is provided at the corner of each L-shaped assembly, and the shape of the provided slit 7 is

[0031] Please also refer to Figures 4, 5, and 6, which are partial schematic diagrams of the above two solutions.

[0032] Figure 4 and Figure 5 show four different shapes of cutouts 7" and 7'' respectively. A cutout combination (composed of 3 cutouts) arranged in a diagonal line is provided on each L-shaped assembly. The selected Appropriate cuts are p...

Embodiment 3

[0034] Such as Figure 7 As shown in Figures 8a to 8c, the movable positioning flange for installing the ventilating fan in this embodiment consists of two pairs of L-shaped assemblies, which are assembled on the two opposite corners of the square frame of the ventilating fan body to form a movable positioning method. Lan, two screw hole slots 6 are provided on each L-shaped assembly, and two sliding slots 5 are provided for sliding connection with the square frame of the ventilation fan body, and each L-shaped assembly An oblique positioning chute 9 is arranged on the corner to match the positioning block structure of the angle iron positioning piece 10, such as Figure 7 shown. The angle iron positioning piece can move in the positioning chute, and the state process of its movement is shown in Figure 8a to Figure 8c (the angle iron moves from the position of the solid line to the position of the dotted line). When the ventilation fan is installed, the two L-shaped assembli...

Abstract

The movable locating flange for fixing the air exchanging fan onto ceiling frame consists of one or two pairs of L-shaped combined parts assembled to the square frame of the air exchanging fan and locating unit to locate the movable locating flange onto the ceiling frame. Each of the L-shaped combined parts has at least two sliding slots for connection with the square frame of the air exchanging fan, and the sliding slots are parallel to the diagonals of the square frame of the air exchanging fan. The L-shaped combined parts have screw holes for screws to penetrate through. During installation, the L-shaped combined parts may be shifted to suit different installation positions, so that the present invention is suitable for different ceiling frames with different sizes.

Description

technical field [0001] The invention relates to an auxiliary device for installing a ventilation fan, in particular to a movable positioning flange. Background technique [0002] Ventilation fan is a widely used indoor ventilation equipment. When installing a ventilation fan on the ceiling, generally a wooden frame is built on the ceiling to form a ceiling frame, and holes for installing the ventilation fan are reserved on the frame. However, in different regions, the size of the wooden frame holes reserved for ceiling wooden frame construction is often different, which brings difficulties to the installation of a ventilation fan product after it is sold to various places. In addition, when the user replaces a new ventilation fan, the installation dimensions of the new and old models of the ventilation fan are also different, which will also cause the trouble of re-construction for replacement and installation.
