Description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing, wherein：
Fig. 1 is a kind of section cut-away illustration of sealing strip of this practicality；
Fig. 2 is the schematic diagram of the application of Fig. 1 sealing strips；
Fig. 3 is the schematic diagram of another embodiment of Fig. 1；
Fig. 4 is the schematic diagram of the another embodiment of Fig. 1.
Specific implementation mode
As shown in Figure 1 and Figure 2, a kind of sealing strip, including the first noumenon 1, the first noumenon 1 are circumferentially provided with several first
Protrusion 2, several first protrusions 2 extend along the length direction of the first noumenon 1, and at least two first protrusions 2 abut close with shell cover 5
Envelope.
First protrusion 2 allows sealing strip to be produced by extrusion molding mode along the length direction extension of the first noumenon 1,
Production efficiency is high.
The present embodiment makes at least two first protrusions 2 by circumferentially disposed several first protrusions 2 in the first noumenon 1
Sealing is abutted with shell cover 5, forms at least two seals, lift-off seal effect.
The present embodiment also replaces the compression of sealing strip to become by decreasing or increasing the gap between two the first protrusions 2
Shape reduces the compression deformation of sealing strip, reduces plastic deformation, so that sealing strip is kept elasticity, keeps good sealing effectiveness.
The present embodiment also by making at least two first protrusions 2 be abutted with shell cover 5, increases the contact of sealing strip and shell cover 5
Area is no longer limited by the width of the first groove 7.
Conventional, shell cover 5 is usually provided with the protrusion towards extension in the first groove 7, and protrusion and the first groove 7 are to close
Strip of paper used for sealing carries out compression seal.
To make sealing strip be preferably bonded with shell cover 5, and then sealing effect is kept, is formed between the first adjacent protrusion 2
First cavity, the first cavity are used to house shell cover 5 towards the protrusion of extension in the first groove 7.
This allows for the surface area that sealing strip is equal to the first cavity with the contact area of shell cover 5, increases sealing strip and shell
The contact area of lid, while the bottom of chamber of the first cavity is contacted with protrusion, also so that the first protrusion 2 is close to protrusion, is not had
Gap.
The present embodiment replaces the compressive deformation of sealing strip by the gap between decreasing or increasing two the first protrusions 2,
It can make the first protrusion 2 that bending deformation occur.
As shown in figure 3, to reduce the deflection of the first protrusion 2, the surface of the first protrusion 2 is provided with for compressive deformation
First recess portion 41.
In order to make sealing strip and the contact area of shell cover 5 increase, two first protrusions 2 should be made to extend opposite to each other, this is allowed for
First protrusion 2 generates compression backwards to the side of shell cover 5.
To reduce compressive deformation of first protrusion 2 backwards to the side of shell cover 5, the first recess portion 41 can be set to the first protrusion
2 backwards to the side of shell cover 5.
First recess portion 41 be located at first protrusion 2 backwards to shell cover 5 side, the first recess portion 41 may be contacted with shell 6 without
Can shrink, the first recess portion 41 can be set to two first raised 2 opposite sides, this be particularly suitable for it is shown in Fig. 3 only
The case where two first protrusions 2.
When the quantity of the first protrusion 2 be it is shown in Fig. 3 three or more when, make the resistance of the first raised 2 bendings deformation
It is larger, it has not been convenient to implement, can be replaced by making each first protrusion, 2 impartial compression, play identical effect.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the first noumenon 1 be additionally provided with connection the first groove 7 the second protrusion 3, second
The outer surface of protrusion 3 is bonded with the side wall of the first groove 7 on shell 6.
The outer surface of second protrusion 3 is bonded with the side wall of the first groove 7, and gas or liquid can be prevented from the second protrusion 3
It is penetrated with the junction of the first groove 7.
To prevent sealing strip to be easily detached from from the first groove 7 on shell 6, the second protrusion 3 is provided with for being clamped first
Second protrusion of the side wall of groove 7 or the second recess portion 4.
Second protrusion is set in the second protrusion 3, the second protrusion is not easy to find accurately, is also easy to be torn in assembly and falls,
So 4 to the second protrusion of the second recess portion has advantage.
Second recess portion 4 can be one, or two, two the second recess portions 4 are symmetrically arranged in the second protrusion 3
Both sides so that sealing strip need not be distinguished positive and negative.
Sealing strip is connect with shell 6 by snap fit, and sealing strip is packed into and removes along the length direction of the first groove 7,
It is also equal to be that sealing strip is packed into and removes along the length direction of shell 6.
Sealing strip is removed along the length direction of shell 6, time-consuming longer, moreover, when sealing strip aging is broken, from shell 6
Many times can be expended by tearing sealing strip open.
In this regard, the quantity of the second protrusion 3 can be two, the bottom for housing the first groove 7 is formed between two the second protrusions 3
Second cavity of wall.
It is mutually close by two second protrusions 3 when this allows for tearing sealing strip open, reduce the resistance of dismounting sealing strip.
Further, the first protrusion 2 is identical as the cross-sectional shape of the second protrusion 3, the first protrusion 2 and the second raised 3 edges
The circumferential direction of the first noumenon 1 is uniformly arranged.
Also make that direction need not be distinguished when assembly sealing strip in this way, meanwhile, sealing strip turns assembly after a period of use,
So that shell 6 and shell cover 5 is connected from the first different protrusions 2, makes sealing strip reversal deformation, extend the service life of sealing strip.
Above example is only to illustrate the technical solution of the utility model and is not intended to limit it, all without departing from this
Any modification of utility model spirit and scope or equivalent replacement should all cover the range in technical solutions of the utility model
It is interior.
