Abstract
A kind of sealing structure is the utility model is related to, discloses the sealing structure between a kind of abdomeinal fin and nacelle.The utility model devises a kind of watertight rubber parts and is installed between abdomeinal fin and nacelle; prevent from reaching watertight requirement inside rain leakage to abdomeinal fin using the compressibility of rubber parts; cable inside abdomeinal fin, electrical connector etc. can effectively be protected; such a sealing structure can improve efficiency of assembling and reduce work hours and improve the overall aesthetics of product.
Description
Technical field
The present invention relates to a kind of sealing structure, the sealing structure between more particularly to a kind of abdomeinal fin and nacelle.
Background technology
The electric products such as cable, connector connector are disposed with inside abdomeinal fin, as met in abdomeinal fin in leakage or the abdomeinal fin of rainwater
Ponding may cause electric product to break down, it is therefore necessary to prevent oozing for rainwater using watertight structure between abdomeinal fin and nacelle
Leakage.At present, it is main between abdomeinal fin and nacelle to reach watertight requirement using the methods of stickup masking foil or dirigible fabric.This method exists
The shortcomings that certain, as pulled down abdomeinal fin in product maintenance or test process, need to re-paste masking foil after abdomeinal fin recovers assembling
Or dirigible fabric and local touch-up paint is needed, add unnecessary man-hour reduces work efficiency and influences the aesthetics of product at the same time.
The content of the invention
The object of the invention：
Invention proposes providing the sealing structure between a kind of abdomeinal fin and nacelle, it is therefore intended that can reach abdomeinal fin and nacelle
Between watertight electric product inside abdomeinal fin is claimed, and can largely improve efficiency of assembling and reduce work hours, while energy
Enough effective overall aesthetics for improving product.
Technical solution of the present invention：
A kind of sealing structure between abdomeinal fin and nacelle, including nacelle 1, watertight rubber parts 2, abdomeinal fin 3 and contiguous block 4；Connection
Block 4 is welded in nacelle 1, and abdomeinal fin 3 is fixed on contiguous block 4 using screw, and encloses closing chamber with nacelle 1, its feature exists
In abdomeinal fin 3 adds watertight rubber parts 2 with 1 junction of nacelle, and watertight rubber parts 2 is cross-section string configuration, and lower section is
U-shaped structure is used to be bonded and is used to reach watertight by compression with nacelle 1 for v-shaped structure with abdomeinal fin 3, upper section.
The watertight rubber parts 2 is silastic product, and cross section structure is divided into upper and lower two sections, and wherein upper section is V-arrangement
Structure, lower section are U-shaped structure.
The abdomeinal fin 3 is square groove stressed-skin construction, and front end is triangular structure, and groove bottom is equipped with and is connected with contiguous block 4
Hole.
The contiguous block 4 is rectangular block architecture, is welded in nacelle 1.
Advantageous effect of the invention：The present invention devises a kind of watertight rubber parts and is installed between abdomeinal fin and nacelle, utilizes rubber
The compressibility of glue part prevents from reaching watertight requirement inside rain leakage to abdomeinal fin, can effectively protect the electricity inside abdomeinal fin
Cable, electrical connector etc., such a sealing structure can improve efficiency of assembling and reduce work hours and improve the overall aesthetics of product.

Embodiment
Below in conjunction with the accompanying drawings, the utility model is described further：
As shown in Figs. 1-3, the sealing structure between a kind of abdomeinal fin and nacelle, including nacelle 1, watertight rubber parts 2, abdomeinal fin 3 and
Contiguous block 4；Contiguous block 4 is welded in nacelle 1, and abdomeinal fin 3 is fixed on contiguous block 4 using screw, and encloses closing with nacelle 1
Chamber, it is characterised in that abdomeinal fin 3 adds watertight rubber parts 2 with 1 junction of nacelle, and watertight rubber parts 2 is cross-section strip knot
Structure, lower section are used to be bonded and are used to reach by compression with nacelle 1 for v-shaped structure with abdomeinal fin 3, upper section for U-shaped structure
To watertight.
Watertight rubber parts 2 is silastic product, and cross section structure is divided into upper and lower two sections, and wherein upper section is V-arrangement knot
Structure, lower section are U-shaped structure.
Abdomeinal fin 3 is square groove stressed-skin construction, and front end is triangular structure, and groove bottom is equipped with the hole being connected with contiguous block 4,
Inside is used to arrange cable, electrical connector etc..
Contiguous block 4 is rectangular block architecture, is welded in nacelle 1.
This sealing structure is installed between abdomeinal fin and nacelle using watertight rubber parts to reach watertight requirement, is made in sealing structure
Watertight rubber parts is designed as complicated cross-section string configuration.As shown in figure 3, specific embodiment party after the assembling of this sealing structure
Method is as follows：
The compression ratio of rubber parts material, the rubber parts material pressure used in the present invention are considered when the 1st, designing watertight rubber parts 2
Shrinkage is 26%；The gap of 2mm is reserved between abdomeinal fin 3 and nacelle 1, rational watertight rubber is designed according to the decrement of rubber parts
Glue part 2；
2nd, determine to cut isometric watertight rubber parts 2 by the length of abdomeinal fin 3 spare；Again by the watertight rubber parts 2 after cutting
The top edge of abdomeinal fin 3 is pasted on, each bonding plane is cleaned before pasting, decontamination processing, so as to carry out good glue
Connect；
3rd, the abdomeinal fin 3 after stickup watertight rubber parts 2 is stood and treats that bonding agent fully cures；Screw is used after curing by watertight
Rubber parts, abdomeinal fin 3 are installed in nacelle 1 by contiguous block 4, ensure that watertight rubber parts 2 is in compressive state.
