Problems solved by technology

[0004] At this time, the mask made of ABS material will cause residual stress in the process of forming the mask due to the characteristics of ABS. Directly use the mounting screws with permeable chemical substances to drive into the mask, especially if the diameter is smaller. When the screw is 4mm, the stress remaining on the mask will concentrate on the screw, and the ABS material mask will crack and break, which may separate the mask from the ceiling.

Embodiment Construction

[0019] like figure 2 and image 3 Shown is a schematic diagram of an embodiment of the present invention. A protrusion 100 with a chute 110 is integrally formed on the ventilation fan cover 1000 as a fixing part. The middle part of the movable part 200 protrudes, and a first threaded opening 220 is formed inside, the periphery 230 is lower than the middle part, and the two sides of the periphery 230 form sliding edges 210 . The movable part 200 can slide into the sliding groove 110 through the sliding edge 210 , that is, it can be freely detachably installed on the protrusion 100 . One end of a curved part 400 is provided with a screw hole 410 , and the other end is against or snapped into the mask 1000 . A screw (not shown in the figure) is screwed into the screw hole 220 through the screw hole 410 to fix the bending part 400 on the movable part 200 , thus the spring 300 is set between the bending part 400 and the movable part 200 .

Abstract

The invention relates to a fixed structure for a ventilator mask and a spring, which is characterized in that a fixed element is formed integrally with the ventilator mask; a movable element can be freely and detachably arranged on the fixed element in a mode of a sliding groove; a bent component of which one end is provided with a screw hole is fixed between the movable element and the ventilator mask; and the spring is sleeved on the movable element. Because no screw is directly acted on the mask, stress can not be generated between the fixed element and the mask, further the mask can not be damaged, and the durability of products is improved.

Description

technical field [0001] The invention relates to a ventilation fan, in particular to a fixing structure for installing a ventilation fan mask spring. Background technique [0002] A ventilation fan is a common air circulation device used to remove air from a room. Just disclose a kind of ventilation fan as Chinese patent ZL95211395.3, just describe that two " eight " font spring clips are housed on the inner surface of panel. [0003] like figure 1 As shown, the main structure of the ventilation fan includes a motor 1, a volute 2, a support plate 3, a box body 4, an air outlet pipe 5, a panel 6, an air outlet 10, an air inlet 11, etc., and two A "eight"-shaped spring clip 7, two metal sheets 12 with holes are installed at the corresponding place of the casing 4, and the spring clip 7 is put into the holes of the metal sheet 12, so that the panel 6 can be conveniently and firmly fixed on the case 4. [0004] At this time, the mask made of ABS material will cause residual s...
