In addition, if there is a description of "first" or "second" etc. in the embodiments of the present utility model, the description of "first" or "second" etc. is only for descriptive purposes, and is not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not within the scope of protection claimed in the present utility model.

As shown in fig. 1 to 3, a negative pressure fan safety net structure integrally formed with a frame includes:

the device comprises a frame body 1, wherein a rectangular opening 11 is formed in one side of the frame body 1, a baffle 21 extends from the inner side of the rectangular opening 11, gaps 211 are formed in the opposite baffle 21 at intervals, and hooks 31 are arranged in the gaps 211;

the net body 22, the side of net body 22 is laminated with baffle 21 mutually, just net body 22 is equipped with the hook groove 32 that cooperatees with hook portion 31, net body 22 passes through hook portion 31 and hook groove 32 demountable installation in the opening part of framework 1.

In actual design, can play the effect to the location of the net body 22 through the setting of baffle 21, hook 31 applys the effort that deviates from baffle 21 horizontal cutting direction to the net body 22 simultaneously, makes the net body 22 collude in framework 1 to the installation of net body 22 has been made things convenient for, and simultaneously the processing step of framework 1 has also reduced, has effectively improved negative pressure fan's installation effectiveness and processing cost.
