DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0024] Example: Figure 1-7 As shown, a filter protection installation mechanism of a ventilation equipment includes a fixed frame 1 and a filter 2, the filter 2 is installed inside the fixed frame 1, a slide bar 5 and a positioning pin 6 are fixedly installed on the inner side of the fixed frame 1, a spring group 10 is fixedly installed inside the positioning pin 6, a movable frame bar 3 is slidably installed on the edge of the fixed frame 1, the outer frame edge of the filter 2 and the two ends of the movable frame bar 3 are provided with a slide groove that matches the slide bar 5, and the outer frame edge of the filter 2 is provided with a positioning groove 9 that matches the positioning pin 6.

[0025] The fixed frame 1 includes a bottom frame 101 and two side frames 102. The two side frames 102 are fixedly installed at both ends of the bottom frame 101 respectively. The inner surface of the bottom frame 101 is fixedly installed with a limit strip 12. The slide bar 5 and the positioning pin 6 are fixedly installed on the inner side surfaces of the two side frames 102. The filter screen 2 is pushed into the notch of the fixed frame 1 by the slide bar until the positioning pin 6 is inserted into the positioning groove 9 to clamp the filter screen 2.

[0026] The slide bar 5 includes a limit head 501 and a fixed base 502. The fixed base 502 is fixedly connected to the inner side of the side frame 102. The limit head 501 is fixedly installed on the top of the fixed base 502. The width of the bottom of the limit head 501 is greater than the width of the top of the fixed base 502 to prevent the filter net 2 from shifting up and down when it is pushed into the fixed frame 1.

[0027] The side frame 102 is laterally penetrated with a through hole, the positioning pin 6 includes a receiving frame 601 and a slider 602, the spring group 10 is fixedly installed on the inner bottom surface of the receiving frame 601, the other end of the spring group 10 is fixedly connected to the bottom of the slider 602, and a movable rod 11 is fixedly installed on the bottom surface of the slider 602, and the movable rod 11 is slidably connected to the bottom of the receiving frame 601. When the filter net 2 is pushed in, the movable rod 11 is pulled outward to compress the spring group 10. After the filter net 2 reaches a suitable position, the movable rod 11 is released to allow the slider 602 to fit into the positioning groove 9.

[0028] A baffle 7 is rotatably installed at the end of the side frame 102, and the end of the baffle 7 extends to the connection between the side frame 102 and the movable frame bar 3. A limit block 8 is fixedly installed at the end of the side frame 102. The baffle 7 prevents the filter screen 2 from sliding out after being pushed into the fixed frame 1, and the limit block 8 limits the baffle 7 from continuing to rotate downward.

[0029] The four corners of the fixing frame 1 are all provided with fixing holes 4, the inner surfaces of the fixing holes 4 are provided with threads, and the fixing frame 1 is fixedly connected to the ventilation device by bolts.

[0030] Working principle: When using the filter protection installation mechanism of this ventilation equipment, first remove the movable frame bar 3, align the slide groove with the slide bar 5 and push the filter 2 in through the notch of the fixed frame 1, pull the movable rod 11 outward to compress the spring group 10, and after the filter 2 reaches the appropriate position, release the movable rod 11 to make the slider 602 snap into the positioning groove 9. At this time, the limit bar 12 snaps into the slot on the edge of the filter 2. After the filter 2 is fully pushed in, insert the movable frame bar 3 into the notch of the fixed frame 1 again, and rotate the blocking bar 7 to above the limit block 8 to prevent the filter 2 from falling off, and complete the installation.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
