Description

Vehicle-mounted anti-dust louver

Technical field

The utility model relates to a kind of louver, and the louver that especially a kind of installation on the rolling stock can be anti-dust, belongs to five metals equipment technical field.

Background technology

Vehicle mounted square cabin is the case body equipment be contained on transport vehicle needing operation operation in the wild for geoexploration, hydraulic engineering, building engineering, army's field operations etc.Be provided with multiple working equipment in shelter, for the ease of shelter inside to separate ventilation, the normal operation of guarantor's below deck equipment, installs air draft louver usually on car wall.Traditional vehicle-mounted louver can be used for ventilating, rainproof, but sand prevention anti-dust performance is poor, is unfavorable for protecting indoor environment.

Utility model content

The purpose of this utility model be to provide a kind of structure simply, not only can ventilation rainproof but also the good vehicle-mounted anti-dust louver of sand prevention anti-dust performance.

The purpose of this utility model is achieved by the following technical programs:

A kind of vehicle-mounted anti-dust louver, comprise rectangular frame, multiple blade, filtering net and baffle plate be arranged in parallel from top to bottom, on the upside of described blade, two ends are hinged with rectangular frame both sides respectively, described filtering net and baffle plate are successively set on outside rectangular frame from inside to outside, filtering net both sides are plugged on rectangular frame both sides respectively, baffle plate is resisted against outside filtering net, and several fastener is each passed through baffle plate both sides and is fixed in rectangular frame.

The purpose of this utility model can also be realized further by following technical measures.

Aforesaid vehicle-mounted anti-dust louver, wherein said rectangular frame both sides go out slot respectively to interior bending, and filtering net both sides are plugged in rectangular frame two side slot respectively.

Aforesaid vehicle-mounted anti-dust louver, wherein said rectangular frame is formed by the welding of multiple zigzag metal piece, is interval with several contiguous block respectively inside the bending edges of rectangular frame both sides.

Aforesaid vehicle-mounted anti-dust louver, wherein said baffle plate is square grid shape structure.

Aforesaid vehicle-mounted anti-dust louver, wherein said baffle plate mesh is greater than filtering net mesh.

The utility model sets up filtering net outside rectangular frame, the sand and dust in the adsorbable blocks air of filtering net, thus effectively prevents sand and dust from entering in cabin by louver, protection indoor environment neat and tidy; Filtering net both sides are plugged in rectangular frame two side slot respectively, are connected firmly, and can take off replacing, convenient maintenance and replacement without the need to any instrument; Baffle plate is resisted against outside filtering net, can be used for leading along filtering net, make outside filtering net smooth, and baffle plate mesh is greater than filtering net mesh, not only can ensures that louver has better air permeability, also can ensure that filtering net gives full play to anti-dust effect; The utility model structure is simple, and cost is low.

Advantage and disadvantage of the present utility model, by for illustration and explanation for the non-limitative illustration passing through preferred embodiment below, these embodiments, only provide as an example with reference to accompanying drawing.

Fig. 2 is I enlarged drawing of Fig. 1;

Fig. 3 is perspective view of the present utility model.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described in further detail.

As shown in Figure 1, Figure 2 and Figure 3, the utility model comprises rectangular frame 1, multiple blade 2, filtering net 3 and baffle plate 4 be arranged in parallel from top to bottom, rectangular frame 1 is formed by the welding of 4 zigzag metal pieces, rectangular frame 1 both sides go out slot 11 respectively to interior bending, are interval with 2 contiguous blocks 12 respectively inside the bending edges of rectangular frame 1 both sides.On the upside of each blade 2, two ends are hinged with rectangular frame 1 both sides respectively, and when not needing to ventilate, rotating blade 2, make upside blade 2 lower end abutment on bottommost blade 2 upper end, realize louver and close, blade 2 also can be fixed in rectangular frame 1.Filtering net 3 and baffle plate 4 are successively set on outside rectangular frame 1 from inside to outside, and filtering net 3 both sides are plugged in rectangular frame two side slot 11 respectively, according to ventilation and anti-dust grade, can select the filtering net 3 of different densities.Baffle plate 4 is square grid shape structure, and baffle plate 4 mesh is greater than filtering net mesh, and baffle plate 4 is resisted against outside filtering net 3, and 4 screws 5 are each passed through baffle plate 4 both sides and rectangular frame 1 both sides bending edges is fixed on the contiguous block 12 inside bending edges.

In addition to the implementation, the utility model can also have other embodiments, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
