Abstract

The utility model provides a frame structure of double ventilated doors, which comprises a first edge door and a second edge door and is characterized in that a contact frame of the first edge door is provided with a convex edge end; a contact frame of the second edge door is provided with a concave nick end at the position corresponding to the convex edge end of the contact frame of the first edge door; when the double ventilated doors are closed, the convex edge end contacts and matches with the concave nick end to block the gap between the ventilated doors and improves the noise isolation and air tightness effects of the double ventilated doors.

Description

A kind of two frame structure of opening Ventilating door

Technical field

The utility model relates to a kind of frame structure, refers to a kind of two frame structure of opening Ventilating door especially.

Background technology

General two Ventilating doors of opening, as shown in Figure 1, after it is assembled on the doorframe, in order to make its first side door 1 and second side door 2 is unlikely blocks mutually, be convenient to open, so must be at first side door 1 and second side door 2 contact the frame corresponding section, leave one clearance 3, but because the relation of this road clearance 3, just can't make and pair open Ventilating door after closing, reach sound insulation and airtight effect.Thereby be necessary to design one and do not hinder and destroy two original open and close functions of Ventilating door of opening, subsidiary again have two Ventilating doors of opening of sound insulation and airtight effect to construct.

The utility model content

The technical problems to be solved in the utility model provides a kind of two border structure of opening Ventilating door, does not hinder and destroys two open and close functions of opening Ventilating door, has sound insulation and airtight effect again.

For solving the problems of the technologies described above, the utility model provides a kind of two frame structure of opening Ventilating door, comprises one first side door and one second side door, and it is characterized in that: the contact frame of this first side door has one; The contact frame of this second side door has a recessed breach end corresponding to the end place, protrusion limit of this first side door contact frame; This pair opens Ventilating door when closing, this protrusion limit end with should recessed breach end be in contact with one another holder and close.

In the such scheme, this frame adopts elastic material, and the preferably can use plastic cement.

In the such scheme, this frame can be made or adopt methods such as setting-in will protrude the limit end to be fixed on the frame with one-body molded.

In the such scheme, the cross sectional shape of this protrusion limit end and recessed breach end can be designed to rectangle or trapezoidal etc.

Open Ventilating door when closing for of the present utility model pair, the corresponding contact jaw driving fit fully of two side doors, thereby can improve two sound insulation and tight functions of opening Ventilating door.

In order further to understand structure of the present utility model and function, cooperate following accompanying drawing now, be described as follows in detail.

Description of drawings

Fig. 1 is the existing two schematic diagram of Ventilating door when closing of opening;

Fig. 2 is the two border structure schematic diagrames of opening Ventilating door of the utility model;

Fig. 3 is the two schematic diagrames of border structure when the door body is closed of opening Ventilating door of the utility model.

The specific embodiment

As shown in Figure 2, the frame that the utility model will this pair be opened first side door 1 of Ventilating door and second side door 2 improves and is designed to make by plastic cement material is one-body molded, and with the corresponding contact frame of this two side door, the contact frame that is designed to first side door 1 has one and protrudes limit end 11, this rear of protruding limit end 11 then is a hollow breach end 12, and the contact frame of second side door 2 is corresponding to end 11 places, protrusion limit of first side door, 1 contact frame, be provided with a recessed breach end 21, and the size dimension of this recessed breach end 21, close with the size dimension of the protrusion limit end 11 of first side door 1, the rear that is positioned at this recessed breach end 21 is then for protruding limit end 22, this protrudes the size dimension of limit end 22, the size dimension of rear hollow breach end 12 that protrudes limit end 11 with first side door 1 is close, make end 11 positions, protrusion limit of the side door 1 of winning, can contact recessed breach end 21 that frame has with second side door 2 and be in contact with one another holder and close.In two pass closed procedures of opening Ventilating door, first side door 1 remains with clearance with second side door, 2 corresponding contact frames and exists, thereby can not have influence on two open and close functions of holding Ventilating door; And two open Ventilating door and close after, by the protrusion limit end 11 of first side door 1 with and the structure design of the recessed breach end 21 of second side door 2, can make protrusion limit end 11 be in contact with one another holder and close, the clearance coverage that exists between first side door 1 and second side door 2 is closed with recessed breach end 21.

Figure 3 shows that the schematic diagram when the two frames of opening Ventilating door of the utility model are configured in a body and close, after two first side doors 1 of opening Ventilating door and second side door 2 are assembled on the doorframe, because of being provided with, the corresponding contact frame of this two side door protrudes limit end 11 and recessed breach end 21, two when opening Ventilating door and closing, just the clearance that exists between this first side door and second side door can be covered and close, make two when opening Ventilating door and closing, the driving fit fully of the contact end of two side doors.

In sum, two border structures of opening Ventilating door of providing of the utility model as can be known by the new space member designs of reasonable utilization one, really can improve two sound insulation and airtight effects of opening Ventilating door, progress on possessing skills and practical value.

Claims
