Abstract
The utility model relates to a sealing device, which adopts an air-tight type, namely, a door frame 2 of a box body door and a heat insulating plate of a bottom plate 7 of a box body are provided with annular close type circular grooves, and an air-tight hose 3 is inserted into the circular groove and is connected with an air supply pipe 5 through a single-way pressure adjusting inverted valve 4. The inner side of the box body door 1 and the corresponding position of the air-tight hose 3 are provided with lug bosses 6, and the bottom plate 7 of the box body close to the point of the box body door 1 is provided with an air discharge switch. When the box body door 1 is closed, a probe of the box body door 1 bears press and shrinks. When the box body door 1 is opened, the probe 9 bounces immediately, the air of the point is released and the box body door 1 is easy to open. The utility model has the advantages of wide application range, good tightness, simple structure, energy saving and low cost.
Description
Technical field:
The utility model relates to a kind of sealing device, particularly relates to a kind of sealing device that is widely used in air-conditioning preservation box, modified atmosphere fresh-keeping storage, freezer door and the sealing of casing internal partition.
Background technology:
Many adhesive tape sealing of the many employings of the sealing of well-known air-conditioning preservation box, modified atmosphere fresh-keeping storage, freezer door at present, adhesive tape easily wears out, leaks gas seriously especially when the speed of a motor vehicle increases, the inside and outside generation pressure reduction gas leakage in storehouse is more serious, can not guarantee to stipulate air pressure in the storehouse, the then unit continuous operation of having to, so waste energy, when running into the road that jolts uneven, because collision, adhesive tape very easily is out of shape and is caused gas leakage, so, freezing and fresh-keeping effect is poor.
Summary of the invention:
Main purpose of the present utility model be to overcome above deficiency and provide that a kind of air-tightness is strong, energy savings, sealing device simple in structure.
The technical scheme that its technical problem that solves the utility model adopts is: it is made up of cabinet door, sealing device, casing, it is characterized in that: sealing device adopts air hermetic, promptly at the enclosed circular groove of warming plate place open loop shape of cabinet door doorframe 2 and box bottom 7, airtight hose 3 is embedded wherein, airtight hose 3 is connected with air supply pipe 5 by unidirectional pressure regulation non-return valve 4, have boss 6 in cabinet door 1 inboard with airtight hose 3 relative position places, near cabinet door 1 place the switch 8 that loses heart is installed on the box bottom 7, is fixed with probe 9 on it.
Advantage and the good effect that the utlity model has are: easy enforcement simple in structure, air-tightness high-preserved effective, can make full use of self energy so energy savings.
Description of drawings:
Fig. 1 is the utility model schematic diagram of sealing device.
Among Fig. 1: 1. cabinet door, 2. doorframe, 3. airtight hose,
4. unidirectional pressure regulation non-return valve, 5. air supply pipe, 6. boss,
7. box bottom, switch, 9. probe 8. lose heart.
The specific embodiment:
For further understanding summary of the invention characteristics of the present utility model and effect following examples for example now, and conjunction with figs. is described in detail as follows, and sees also Fig. 1.
As shown in Figure 1: the circular groove that has annular enclosed type at the warming plate place of cabinet door 1 doorframe 2 and box bottom 7, airtight hose 3 is embedded wherein, airtight hose 3 is connected with air supply pipe 5 by unidirectional pressure regulation non-return valve 4, have boss 6 in cabinet door 1 inboard with airtight hose 3 relative position places, after airtight hose 3 inflations, promptly expand, the boss 6 of cabinet door 1 inboard just pushes the airtight hose 3 that is placed in cabinet door doorframe 2 and the box bottom 7 warming plate place grooves at closing time, reaches the purpose of sealing.On the box bottom 7 near the cabinet door 1 place fixed installation switch 8 that loses heart, its pop one's head in 9 pressurizeds and indentation when having probe 9. cabinet doors 1 on it and closing, when opening the door, probe 9 ejects immediately then that the gas at this place is released, air pressure decline cabinet door 1 is easy to be opened.The effect of unidirectional pressure regulation non-return valve 4 is to guarantee when unit quits work, and still can keep the pressure of former setting constant in the airtight hose 3, and then sealing effectiveness is constant.Gas source in the airtight hose 3 can be that the gas that unit self produces in air-conditioning preservation box, the modified atmosphere fresh-keeping storage also can adopt external automobile cylinder gas or add the gas that little shape air compressor machine produces.
The utility model has the advantages that: applied range, good seal performance, the reality of being convenient to simple in structure Execute, energy savings, cost be low.
