Abstract
The utility model relates to sealing device technical fields.The utility model discloses a kind of sealing strips of high leakproofness, are mounted on cabinet, comprising: connector, the first seal, the second seal and third seal；The connector is in "-" type, and first seal, the second seal and third seal set gradually the top of the connector；Second seal and the third seal are in inverted u-shaped, and the both ends of the both ends of second seal and the third seal are fixedly connected with the connector；First seal lower end is vertical with the connector to be fixedly connected, and first seal upper end is bent in an arc shape the place side for stretching to second seal.By the above-mentioned means, the utility model can guarantee and enhance sealing effect, there is high leakproofness；The pretightning force that it reaches required when sealing effect is smaller；It can also avoid that the performance of cracking influence refrigerator occurs because local stress is big；And structure is simple, installation connection is easy.
Description
Technical field
The utility model relates to sealing device technical fields, more particularly to a kind of sealing strip of high leakproofness.
Background technique
Sealing strip on current refrigerator U-shaped structure mostly.When installation, the U-type groove on the sealing strip of U-shaped structure is stuck in
Between door body and strip metal plate, strip metal plate can connect the fixed edge for carrying out compressing sealing strip by screw with door body.?
Under the premise of the sealing strip has certain elasticity, then can be real by way of applying pretightning force between door body and refrigerator body
The effect now sealed.But the sealing strip of the U-shaped structure has the drawback that
1, the installation of sealing strip is needed using strip metal plate and screw；Installation effectiveness is low, and maintenance replacement cost is high.
2, the material of sealing strip is blocked up, needs very big pretightning force that can realize the item number between door body and refrigerator body
Sealing effect, and poor sealing effect.
3, concentration is compared by the position stress that strip metal plate compresses on sealing strip, is easy cracking, protected to will lead to sealing
Temp effect is deteriorated, and then influences the normal use of refrigerator.
Utility model content
The utility model, can be close by three mainly solving the technical problems that provide a kind of sealing strip of high leakproofness
Seal structure guarantees and enhances sealing effect, has high leakproofness, can also be largely avoided condensation icing.
In order to solve the above technical problems, the technical solution that the utility model uses is: providing a kind of high leakproofness
Sealing strip is mounted on cabinet, comprising: connector, the first seal, the second seal and third seal；The connector
In "-" type, first seal, the second seal and third seal set gradually the top of the connector；Described
Two seals and the third seal are in inverted u-shaped, and the two of the both ends of second seal and the third seal
End is fixedly connected with the connector；First seal lower end is vertical with the connector to be fixedly connected, and described first
Seal upper end is bent in an arc shape the place side for stretching to second seal.
Preferably, the third seal is concordant with second seal；First seal is higher than described second
Seal.
Preferably, the distance between first seal and second seal are greater than the third seal and institute
State the distance between second seal.
Preferably, the connector is fixed on the cabinet, and first seal is arranged close to the box inside.
Preferably, the connector, the first seal, the second seal and third seal are integrated chemical conversion type.
The beneficial effects of the utility model are: the utility model can be guaranteed by three seal structures and enhance sealing effect
Fruit has high leakproofness, can also be largely avoided condensation icing；Its reach pretightning force required when sealing effect compared with
It is small；It can also avoid that the performance of cracking influence refrigerator occurs because local stress is big；And structure is simple, installation connection is easy.
Detailed description of the invention
Fig. 1 is a kind of schematic view of the front view of one preferred embodiment of sealing strip of high leakproofness of the utility model.
The components in the drawings are labeled as follows: 1, the first seal；2, the second seal；3, third seal；4, it connects
Body.
Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
Referring to Fig. 1, the utility model embodiment includes:
A kind of sealing strip of high leakproofness, comprising: connector 4, the first seal 1, the second seal 2 and third seal
3；The connector 4 is in "-" type, and first seal 1, the second seal 2 and third seal 3 set gradually the company
The top of junctor 4；The connector 4 is fixed on cabinet, and first seal 1 is arranged close to the box inside.It is described
Connector 4 is for connecting the first seal 1, the second seal 2, third seal 3 and cabinet.The connector 4 may insure
This sealing strip and cabinet are connected firmly, effectively avoid falling off, warpage the defects of.Second seal 2 and third sealing
Body 3 is in inverted u-shaped, and the both ends of the both ends of second seal 2 and the third seal 3 are solid with the connector 4
Fixed connection；First seal, 1 lower end is vertical with the connector 4 to be fixedly connected, the 1 upper end curved bend of the first seal
Folding stretches to the place side of second seal 2.The third seal 3 is concordant with second seal 2；Described first is close
It seals body 1 and is higher than second seal 2；The distance between first seal 1 and second seal 2 are greater than described the
The distance between three seals 3 and second seal 2.The connector 4, the first seal 1, the second seal 2 and
Three seals 3 are integrated chemical conversion type, produce and process easy, simple and convenient, high production efficiency.
First seal 1 is first of sealing of box inside, when by certain pressure, the first seal 1
Be bent in an arc shape end can deformation occurs be adjacent to external door realize sealing effect.
Second seal 2 is one intermediate of sealing, and when by certain pressure, the second seal 2 can be sent out
Raw deformation is adjacent to the effect that external door further realizes sealing.
The third seal 3 is three seals, and when by certain pressure, shape can occur for third seal 3
Change is adjacent to the effect that external door further realizes sealing, guarantees the leakproofness of box house.
The utility model can guarantee and enhance sealing effect, have high leakproofness, can also be largely avoided
Condensation freezes；The pretightning force that it reaches required when sealing effect is smaller；It can also avoid that the shadow that cracks occurs because local stress is big
Ring the performance of refrigerator；And structure is simple, installation connection is easy.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other related technical areas are also included in the patent protection scope of the utility model.
