Description

Quickly-assembled and disassembled ventilation opening

Technical Field

The utility model relates to a vent especially relates to a vent that can swiftly install and remove, belongs to building decoration technical field.

Background

Ventilating holes are normally arranged on the outer wall of a modern building, and in order to prevent dust, rainwater and the like from directly entering a room through the ventilating holes, a ventilating opening with a water retaining, filtering and drainage structure is usually arranged at the ventilating holes.

To the applicant's knowledge, the structure of the existing vents makes their installation with the aid of tools and fasteners, inconvenient to disassemble and clean.

Disclosure of Invention

An object of the utility model is to provide the vent that can swiftly install and remove to the shortcoming that exists among the prior art through institutional advancement.

In order to achieve the purpose, the basic technical scheme of the ventilation opening which can be quickly assembled and disassembled of the utility model is as follows: the filter comprises a circular tube body, a door-shaped barrier strip, an inner plate, a filter device and an outer cover, wherein the inner plate is matched with the barrier strip in shape, the outer contour of the inner plate is matched with the barrier strip, the middle of the inner plate is provided with a round hole, the outer contour of the filter device is matched with the round hole, the inner side and the lower side of the outer cover are open, and the inner contour of the outer cover is matched with the barrier strip;

the outer end of the body is fixedly connected with the inner plate, the barrier strip is fixedly connected with the outer cover, and the inner plate is clamped on the barrier strip;

the excircle of body sets up three circumference equipartition and the elasticity that the axial extends inwards at least and props the claw, the round hole upper end of inner panel is equipped with fender hook down, filter equipment's upper end blocks keep off hook, and the lower extreme links firmly with the inner panel is removable.

Like this, during the installation, insert the ventilation hole on the wall with the body, with the help of elasticity prop the claw location can, very convenient. When the filtering device needs to be cleaned, the lower side opening of the outer cover can be pulled out only by loosening the fixed connection part at the lower end of the filtering device, and the filtering device is very convenient.

The utility model discloses a further perfection is, the cross-section of blend stop is the grooved rail form, the outline of inner panel have with the turn-ups of grooved rail adaptation, by supreme cartridge in blend stop down.

The utility model discloses further perfect is, the body has the flange limit, open the round hole that has the concave ring limit in the middle part of inner panel, the concave ring limit with flange limit adaptation.

The utility model discloses still further perfect is, concave ring limit makes down fender hook.

The utility model discloses still further perfect is, the lower extreme of inner panel extends the drainage hem, the mass flow folded edge is rolled over respectively to the both sides of drainage hem.

Detailed Description

Example one

As shown in fig. 1 to 4, the quickly detachable ventilation opening of the present embodiment includes a circular pipe body 1 having a flange 1-1, a gate-shaped barrier 2 having a channel-shaped cross section, a rectangular inner plate 3, a circular louver 4 serving as a filter, and a cover 5 having an inner contour adapted to the barrier 2, and the cover 5 is open at an inner side and a lower side.

The inner plate 3 has a flange 3-1 adapted to the groove rail of the barrier strip 2, so that the inner plate can be inserted into the barrier strip 2 from bottom to top and then positioned by a positioning pin. The middle part of the inner plate 3 is provided with a round hole 3-2 with a concave ring edge 3-4, the concave ring edge 3-4 is matched with the flange edge 1-1, and a downward baffle hook 3-3 is manufactured on the concave ring edge 3-4 at the upper end of the round hole 3-2. The lower end of the inner plate 3 extends out of a drainage folded edge 3-5, and two sides of the drainage folded edge 3-5 are respectively folded out of a flow collection folded edge 3-6, so that dripping water can be led to the middle of the lower part of the inner plate.

The outer end of the body 1 is fixedly connected with the inner plate 2 through spot welding by clamping the flange edge 1-1 into the concave ring edge 3-4, and the barrier strip 2 is fixedly connected with the inner side of the outer cover 5 through spot welding. The excircle of the body 1 is punched to form three elastic supporting claws 1-2 which are uniformly distributed in the circumferential direction and axially extend inwards. The upper end with the concave annular edge 3-4 clamps the stop hook 3-3, and the lower end is detachably and fixedly connected with the inner plate 3 by a screw 6.

When the vent capable of being quickly assembled and disassembled is installed, the body is inserted into the ventilation hole in the wall and is positioned and fixed firmly by the elastic supporting claw. When needing the clearance, can loosen the screw, directly take out circular shutter plate from the downside of dustcoat is uncovered, also can take out the inner panel from the grooved rail of blend stop downwards earlier, take off circular shutter plate again, it is very convenient.

In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope of the present invention.
