The dustproof filter screen device of said structure exists following defective: 1, the installation and removal operation of filter core is more loaded down with trivial details, because filter core is a large amount of dust of absorption easily, need to often change, and cooperate with nut by screw press box is fixed filter core on screen cover, when filter core is installed, need press box is closely attached on filter core, re-use the instrument clamp nut with fixing press box, during the dismounting filter core, need tool using dismounting nut, take off successively again press box and filter core, like this, so that the installation and removal of filter core operation is all comparatively loaded down with trivial details, be not easy to staff's operation, cause operating efficiency low, the waste of manpower cost; 2, by press box compressing filter core, and need to be on screen cover self-clinching stud and configure the nut of respective numbers, like this, cause the processing technology of dustproof filter screen device comparatively complicated, manufacturing cost is high.
Summary of the invention
The utility model is to solve the existing filter core dismounting inconvenience of existing dustproof filter screen device, processing technology is complicated, manufacturing cost is high technical problem, provides a kind of and is convenient to that filter core dismounting, processing technology are simple, the dustproof filter screen device of low cost of manufacture.
For solving the problems of the technologies described above, the utility model adopts technical scheme as described below.
A kind of dustproof filter screen device, it includes: a screen cover, it includes a screen cover framework and and is located at the ventilation front plate that is formed with some air vents on its of described screen cover frame front end face place; One filter core, it is located among the described screen cover framework and attaches the back side of described ventilation front plate; At least one strip elastic component is located at the back side place of described filter core, and the two ends of described strip elastic component respectively clasp joint and are oppressed described filter core and made it be closely attached on described ventilation front plate on described screen cover.
In the above-mentioned dustproof filter screen device, described strip elastic component is spring.
In the above-mentioned dustproof filter screen device, the two ends of described spring places respectively is formed with a hook, is formed with the clasp joint position on the described screen cover framework, and described hook hook is located among the described clasp joint position and is realized the clasp joint of described spring and described screen cover.
In the above-mentioned dustproof filter screen device, described filter core is tabular.
In the above-mentioned dustproof filter screen device, set spring is two, vertically is arranged on the described screen cover.
In the above-mentioned dustproof filter screen device, place, the both sides, the back side of described screen cover framework arranges respectively at least one grab.
In the above-mentioned dustproof filter screen device, set grab is four, divides equally the place, both sides, the back side in described screen cover framework.
Useful technique effect of the present utility model is: this dustproof filter screen device is fixed filter core on screen cover in the strip elastic component on the screen cover by clasp joint, than existing dustproof filter screen device, the staff need not the dismounting that tool using can be realized filter core, made things convenient for the staff to carry out the dismounting operation of filter core, and can increase work efficiency significantly; And, replace press box to be used for fixedly filter core with the strip elastic component of clasp joint on screen cover, simplified structure and the processing technology of dustproof filter screen device, help to reduce manufacturing cost.
Description of drawings
Fig. 1 is the structural representation of existing dustproof filter screen device.
Fig. 2 is decomposition texture schematic diagram of the present utility model.
Fig. 3 is the draw bail schematic diagram of screen cover of the present utility model and spring.
Fig. 4 is the enlarged drawing of the A part of Fig. 3.
The specific embodiment
For making those skilled in the art more be expressly understood technical problem to be solved in the utility model, technical scheme and useful technique effect, below in conjunction with drawings and Examples the utility model is further elaborated.
Dustproof filter screen device disclosed in the utility model can be used for the electronic equipment such as frequency converter etc., and it arranges the ventilating opening place of electronic equipment, to play the effect of dust control by ventilation.Consult Fig. 2 to shown in Figure 3, this dustproof filter screen device includes a screen cover 10, a filter core 12 and two springs 14.
In the embodiment shown in the figures, for adopting two vertically to be arranged at spring 14 on this screen cover 10 with that filter core 12 compressing is fixing, yet, embodiment shown in the drawings is not limited to the utility model, in other embodiment, the more or spring still less 14 of number also can be set to fix this filter core 12.Certainly, the set-up mode of spring 14 also is not limited to the shown mode of accompanying drawing, and the setting party that can change according to actual needs this spring 14 is to, for example horizontally set or oblique setting.
