Embodiment 1

[0032] Such as Figure 1~3 As shown, a multi-angle quick-installation fan casing includes a casing 1 and a muffler 2 sleeved outside the casing 1. Both ends of the casing 1 and the muffler 2 are connected to each other through a metal expansion joint 8 , so that there is a vacuum layer 7 between the muffler 2 and the casing 1 .

[0033] The outer side of the muffler 2 is provided with several sets of mounting rings 3 around its circumference, and the bottom of each mounting ring 3 is also fixedly connected with a number of mounting feet 4, and several sets of threaded mounting holes 29 are arranged at equal intervals on the mounting ring 3, and the mounting feet 4 The mounting leg 4 is fixedly connected with the mounting ring 3 through the cooperation of the screw 30 and the threaded mounting hole 29 . The bottom of the mounting foot 4 on the same mounting ring 3 is fixedly connected with a fixed frame 5, and the bottom of the fixed frame 5 is also provided with a plate-type ...

Embodiment 2

[0041] Figure 6 It is another fan casing installation method of the present invention, which fixes the mounting feet 4 outside the muffler, the fixed frame 5 and the plate rubber vibration isolator 6 on the left and right sides of the muffler 2, so that it can be installed in a small Installation on the top of the space.

Abstract

The present invention relates to the field of fan casings, in particular to a multi-angle quick-installation fan casing, including a casing, a muffler is sheathed outside the casing, and a metal expansion joint is provided at both ends of the casing. There is a vacuum layer between the muffler and the casing, and several sets of mounting rings are arranged around the outside of the muffler, and several mounting feet are fixedly connected to the mounting rings. The bottom of the support foot is fixedly connected with a fixed frame, and a plate type rubber vibration isolator is also arranged at the bottom of the fixed frame. The invention overcomes the defect that the installation structure of the fan casing in the prior art cannot be adjusted according to the actual situation, and the invention can realize a multi-angle installation structure, thereby achieving the purpose of fast installation, and at the same time, it has the effect of splicing and extension and With multiple mute effects, it can effectively reduce noise during operation.

Description

technical field [0001] The invention relates to the field of fan casings, in particular to a multi-angle quick-installation fan casing. Background technique [0002] Axial flow fans have a wide range of uses, that is, the airflow in the same direction as the axis of the fan blades, such as electric fans and air conditioner external fans are axial flow fans. It is called "axial flow" because the gas flows parallel to the shaft of the fan. Axial flow fans are usually used in occasions with high flow requirements and low pressure requirements. Axial fans hold the position and move the air. The axial flow fan is mainly composed of the fan impeller and the casing. [0003] The position of the casing of the existing axial flow fan is usually fixed during the installation process. The reason is that the positions of the mounting feet of the existing fan casing are fixed and cannot be adjusted according to the actual situation. The installation of the location needs to install b...
