Abstract

The utility model relates to a fresh air indoor device combined filter net frame, which comprises a frame body, the two ends of the frame body is a big end and a small end respectively. A location protruding edge or block is arranged outside or inside between the big end and the small end. The big and the small end can be suited and inserted together mutually. The utility model also comprises an outside end frame body with a handle, the handle is connected with an end of the outside frame body, and the other end of the outside end net frame is inserted mutually with an end of the frame body. The utility model has the advantages of randomly combining one to a plurality of layers filter net with a plurality of combination modes, inserting into the ventilation device through wall pipe after combination, and easy installation and assembly.

Description

The register one's residence modular filter net fixed frame of device of new wind

Technical field

The utility model relates to a kind of annex of ventilation unit, specifically is the register one's residence modular filter net fixed frame of device of a kind of new wind, is used for screen pack is fixed in the wall pipe of ventilation unit.

Background technology

The screen pack of filtered air generally all is housed in the wall pipe of existing ventilation unit, and its structure is directly fixing or is stuck in the wall pipe.Its shortcoming is bad loading and unloading, can not assemble the multilayer net arbitrarily.

Summary of the invention

The purpose of this utility model just provides the register one's residence modular filter net fixed frame of device of a kind of new wind, to solve the bad loading and unloading that prior art exists, the problem that can not assemble the multilayer net arbitrarily.

The technical solution of the utility model is: comprise basic framework, the two ends of this basic framework are respectively stub end and little head end, and the outside between this stub end and little head end or inboard are provided with location fin or projection; The little head end of different described basic frameworks with stub end mutually fit be plugged on.

Also comprise inner framework, one end inboard is provided with interior fin, and an end of this inner framework is pegged graft with described basic framework one end and cooperated.

The outer end framework that also comprises a band handle, handle is connected the outer end of this outer end framework, and an end of the inner of this outer end screen frame and described basic framework or an end of inner framework are pegged graft mutually and are cooperated.

Bottom at the end that handle is arranged of described outer end framework is provided with the dash convex edge.

The utility model has the advantages that: have multiple compound mode to be arbitrarily made with one to multiple layer screen pack, insert after the combination in the wall pipe of ventilation unit again, loading and unloading are safeguarded very convenient.

The specific embodiment

Referring to Fig. 1, the two ends of basic framework 1 of the present utility model are respectively stub end 11 and the microcephaly holds 12, hold the outside between 12 to be provided with location fin 13 (or projection) at this stub end 11 and microcephaly.

As shown in Figure 2, the microcephaly of different several basic frameworks 1 hold 12 with stub end 11 mutually fit be plugged on.Can between per two adjacent basic frameworks 1, be provided with screen pack A.

Referring to Fig. 3～Fig. 5, this embodiment comprises the outer end framework 2 of a band handle 22, and handle 22 is connected the right-hand member (referring to Fig. 4 and Fig. 5) of this outer end framework, and an end of the other end of this outer end framework 2 and described basic framework 1 is pegged graft mutually.Also can be provided with dash convex edge 23 in the bottom that a handle end of 22 is arranged of described outer end framework 2.Outer end framework 2 generally is mounted in the indoor end (right-hand member of Fig. 8) of wall pipe B when using.

Referring to Fig. 6, this is the structure of inner framework 3 embodiment of the present utility model, and the right-hand member inboard of this inner framework 3 is provided with interior fin 31, and the left end of this inner framework 3 is pegged graft with the outside of described basic framework 1 little head end or outer end framework 2 and cooperated.This inner framework 3 in use, both can peg graft and make up (as Fig. 7) with described outer end framework 2, also can hold 12 grafting combinations (referring to Fig. 8) with the microcephaly of basic housing 1, combination among Fig. 8 has comprised three embodiment of the present utility model, promptly is inner framework 3, basic framework 1 and outer end framework 2 from left to right successively.Middle basic framework 1 can a plurality of grafting combinations.

Framework

1,2 of the present utility model and 3 front shape can be circular, rectangle or other Any shape.
