Abstract

The utility model discloses an inflatable normal pressure sealing device which is composed of a dovetail type pipe bearing groove and an inflatable hose. The inflatable hose is inlaid in a dovetail groove. The inflatable hose is pressed to the plain face of a sealed member to form a tight sealing caused by that the inflatable hose is inflated to deform after being inflated. The utility model has high tightness and the inflatable hose can be replaced, having the application for the sealing of doors, windows, refrigerators and other devices.

Description

The utility model relates to a kind of inflatable normal pressure seal arrangement, is the normal pressure seal arrangement that a kind of sealing that can be used for house and door-window and even refrigerator etc. are located to seal.

The sealing of door and window can prevent the cold and hot interchange of outer air within doors, and heating and indoor maintenance uniform temperature are had bigger effect.But at present the sealing of door and window is finished by " press strip glue ", but that in a single day glue come off is just poorly sealed, seals a normal unlatching that also is not easy to press strip glue or other sealer.The sealing of miscellaneous equipment is modal to be the sealing of refrigerator, and what mainly adopt is the magnetic strip of paper used for sealing, and main shortcoming is that assembling is time-consuming, and magnetic stripe is oppositely packed into, and the size of magnetic patch and sleeve does not match.Other has a kind of convex-concave sealed door, and depressed part is housed on the doorframe, and jut is housed on gasket, and jut that door is sealed up when closing and the depressed part on the doorframe form air chamber.Because convex-concave portion is rubber and makes, therefore contact bad will cause poorly sealed.

The purpose of this utility model is the seal arrangement that a kind of new sealing of design is firm and can conveniently open.

Scheme of the present utility model is as follows: inflated hose is inlayed in being in the charge of of dovetail type in the groove, is pressed on the sealed plane by the dilatancy after the flexible pipe inflation, thereby forms sealing closely.

The utility model is simple in structure, and is easy for installation.Inflated hose is also replaceable.The empennage of dovetail groove is highly polished, also can be applicable to the sealing that the refrigerator that tightness has relatively high expectations, fresh-keeping frame etc. are located, and also can be applicable to the sealing of door and window.Good seal performance is convenient to normal unlatching, does not also influence the sealability of door and window.

Below in conjunction with accompanying drawing the utility model is illustrated:

Fig. 1, Fig. 2 are embodiment of the present utility model.

The groove (1) of being in the charge of of dovetail type is fixed on sealed (5), is inlaid with inflated hose (2) in the dovetail groove (1).The diameter of inflated hose (2) is greater than being in the charge of the dark and wide of groove, the inflation rear hose can not deviate from groove, but there is the sub-fraction cambered surface in dovetail groove (1), to give prominence to, dovetail groove is made microscler, be fixed together with one of sealed (5), sealed (4) and (5) when need seal (as door and window) closely stick together the two with lock or latch, make the tail surface of sealed (4) and dovetail groove form an excellent contact face, and because the gas pressure face is adjacent in the inflated hose, thereby reached tight tightness.

Valve cock (3) is stretched outside sealed (5), and long strip dovetail groove (1) can be fixing by screw (6) and sealed (5).

The utility model sealing is firm, can be used for the sealing of door and window, also can be used for the sealing of refrigerator.

Inflated hose also can often be changed.

Claims

1, inflatable normal pressure seal arrangement, it is characterized in that on sealed (5), being fixed with dovetail type and be in the charge of groove (1), the groove of being in the charge of of dovetail type is embedded in inflatable flexible pipe (2), and inflated hose (2) is filled with air and forms sealing closely on the plane that dilatancy is pressed on sealed (4).

2, inflatable normal pressure seal arrangement according to claim 1 is characterized in that above-mentioned inflated hose (2) inflation back diameter is in the charge of the dark and wide of groove (1) greater than dovetail type.
