Body and the sealant for connecting first shell and second shell, the first shell are equipped with first connecting portion, and the second shell is set
There is second connecting portion, a link slot is collectively formed in the first connecting portion and second connecting portion, and the sealant is contained in connection
In slot.
The link slot includes bottom surface, the first side and second side for being connected to bottom surface both side, first side and second
Side is less than the width of bottom surface in one notch of the opposite formation in that side far from bottom surface, the width of the notch.
The link slot is trapezoidal.
The sealant is concordant with notch.
The first connecting portion is equipped with a notch on the outside, and is equipped with a protrusion, institute in one end towards second shell
It states second connecting portion and is equipped with an interference position towards one end of first shell, the protrusion protrudes into interference position and passes through supersonic welding
It connects and is connect with second connecting portion, the second connecting portion is collectively formed described against the end face of notch and the notch of first connecting portion
Link slot.
The bottom surface of the link slot and first side are located in first connecting portion, and the second side of link slot is located at the
On two interconnecting pieces.
The protrusion is resisted against the side wall of the interference position of the second connecting portion.
The sealant is made of epoxy resin.
The first shell is made of plastic cement.
The second shell is made of plastic cement.
The utility model has the beneficial effects that the waterproof connecting structure of the utility model include first shell, second shell and
Sealant is attached in the junction of first shell and second shell by ultrasonic bonding, and is set in the periphery of junction
Set link slot, and sealant be set in link slot, achieve the effect that waterproof, and avoid may cause with glue bonding it is outer
Sight problem.
Detailed description of the invention
In order to be further understood that the feature and technology contents of the utility model, please refer to practical new below in connection with this
The detailed description and accompanying drawings of type, however, the drawings only provide reference and explanation, is not used to limit the utility model.
In attached drawing,
Fig. 1 is the schematic diagram of the utility model waterproof connecting structure.
Specific embodiment
Further to illustrate technological means and its effect that the utility model is taken, below in conjunction with the utility model
Preferred embodiment and its attached drawing are described in detail.
Referring to Fig. 1, the utility model provides a kind of waterproof connecting structure, comprising: first shell 2, second shell 4 and company
Connect the sealant 6 of first shell 2 Yu second shell 4.The first shell 2 is equipped with first connecting portion 22, and the second shell 4 is set
There is second connecting portion 42, a link slot 8 is collectively formed with second connecting portion 42 in the first connecting portion 22, and the sealant 6 holds
It is contained in link slot 8.By forming link slot 8 in the junction of first shell 2 and second shell 4, and fill in link slot 8 close
Sealing 6 had not only avoided prior art glue and has been bonded the problem of appearance that may cause, but also greatly ensure that the effect of product waterproof
Fruit.
The link slot 8 includes bottom surface 82, the first side 84 and second side 86 for being connected to 82 two sides of bottom surface, the first side
Face 84 is less than bottom surface in the width far from one notch 88 of the opposite formation in that side of bottom surface 82, the notch 88 with second side 86
82 width.Preferably, the link slot 8 is trapezoidal.The sealant 6 is concordant with notch 88.The notch 88 of the link slot 8
Be narrower than the trapezium structure or class trapezium structure of bottom surface 82, strengthen after sealant 6 solidifies with first shell 2 and second shell 4
