Seal nipple provided in an embodiment of the present invention includes sleeve pipe, retaining ring 105 and buckle.Its middle sleeve is used to wear to treat
Seal, part to be sealed can be power line, such as the power line of air-conditioner outdoor unit, it can also be used to wear other parts to be sealed, no
A kind of power line this form is confined to, in order to make it easy to understand, being illustrated hereinafter so that part to be sealed is power line as an example.
The first end of sleeve pipe is one end for inserting cable-through hole 109, and by taking air-conditioner outdoor unit as an example, cable-through hole generally opens up
With on the metal lifting handle of outdoor unit, metal lifting handle is sheet metal component.Retaining ring 105 is sheathed on the outer wall of sleeve pipe, and is located at sleeve pipe
First end, the end of the first end of sleeve pipe stretches out retaining ring 105 and forms retaining section 103, and retaining section 103 is used to insert cable-through hole
In 109, the wall thickness of the length of retaining section 103 at least above the hole wall of cable-through hole 109 so that at least part of retaining section 103
Cable-through hole 109 can be passed through to enter inside cable-through hole 109.
Buckle is arranged on the outer wall of retaining section 103, and the hole wall with cable-through hole 109 is formed between buckle and retaining ring 105
The neck of clamping, the present invention clamp the hole wall of cable-through hole 109 by buckle and retaining ring 105, so as to which seal nipple be fixed on
On sheet metal component (metal lifting handle of outdoor unit) where cable-through hole.
Seal nipple provided by the invention when mounted, insert in cable-through hole, is buckled in the presence of external force by retaining section 103
It is caught in along assembly direction in cable-through hole 109, the neck formed by buckle and retaining ring 105 clamps the hole wall of cable-through hole, makes
Seal nipple is obtained effectively to be fitted close with opening up the sheet metal component of cable-through hole.Retaining section 103 can prevent outside rainwater from entering line
Kong Hou, will not directly following current on electricity piece, but blocked by the annular of retaining section 103.Retaining ring 105 enables to rainwater will not
Enter directly into cable-through hole, but blocked by retaining ring 105, play certain rainproof effect.During present invention assembling, only need
Inserting cable-through hole and can reach sealing effectiveness, compared with prior art, reduce assembly process, required part is relatively fewer,
Manufacturing cost is reduced, a seal nipple can save 12 yuan or so of cost.

Abutted with the inwall of cable-through hole 109, limit rib 102 is preferably two, and is distributed with the axisymmetrical of retaining section 103.Sealing
After joint is installed in place, limit rib 102 can abut with the inwall of cable-through hole, so as to prevent seal nipple in the presence of external force
Swing, play limited support effect.
In a specific embodiment of the invention, buckle comprises at least the first buckle 101 and the second buckle 104, the first buckle
The first neck is formed between 101 and retaining ring 105, the second neck is formed between the second buckle 104 and retaining ring 105；First card
The length of groove is more than the length of the second neck.The contact area of first buckle 101 and the hole wall of cable-through hole is more than the second buckle 104
With the contact area of the hole wall of cable-through hole.
In the present embodiment, seal nipple assembling when, the first buckle 101 in the presence of external force along assembly direction first
It is caught in cable-through hole so that seal nipple can only move on assembly direction, in dieback state.Second buckle 104 passed through
Cooperation of being full of firmly can be caught in cable-through hole at this moment, and seal nipple passes through the first buckle 101, the position-limiting action of the second buckle 104
Under can be effectively fitted close with sheet metal component.
Further, in the vertical direction, the first buckle 101 are located at the top of the second buckle 104, i.e., area it is larger
One buckle 101 is in the top of less second buckle 104 of area, and power of the power line on gravity direction causes seal nipple to produce
Raw to reverse, the first buckle 101 is close to sheet metal component side wall, can undertake larger external force, coordinates close.Only enter on gravity direction
Row destructive force that could separate the first buckle 101 with sheet metal component, ensure that the validity of structural member.
In a specific embodiment of the invention, the external diameter of retaining ring 105 is 1.2-2 times of the aperture of cable-through hole 109.Dash
Enclosing 105 external diameters, to be designed as bigger rainproof effect better, but can increase small product size, increases cost, and the present invention is by retaining ring
105 external diameter is preferably designed for 1.5 times of the aperture of cable-through hole 109.It should be noted that retaining ring 105 can and it is non-critical
Circular configuration is designed as, can be by the corresponding portion of retaining ring 105 in order to avoid the miscellaneous part or other purposes on sheet metal component
Position is removed, to form the kidney-shaped structure shown in Fig. 1.
As shown in figure 1, the width of buckle is less than the width of retaining ring 105.The width of buckle refers to that buckle exceeds retaining section
103 part, the width of corresponding retaining ring 105 refer to that retaining ring 105 exceeds the part of retaining section 103.
In a specific embodiment of the invention, sleeve pipe includes the first pipeline section of the first pipeline section 106, the second pipeline section 107 and connection
106 and the transitional pipe segment 108 of the second pipeline section 107, the first pipeline section 106 is used to connect with cable-through hole 109, i.e., retaining section 103 is positioned at the
On one pipeline section 106.After sleeve pipe assembling in place, the axis of the first pipeline section 106 and the axis coaxle of cable-through hole 109, i.e. the first pipeline section
106 vertically the surface with the sheet metal component where cable-through hole, the second pipeline section 107 are arranged in a vertical direction.
In the present embodiment, sleeve pipe has return trap structure so that sleeve pipe when by drenching with rain up and down, water all without
Enter directly on electricity piece, but blocked by return trap, play optimal waterproof effect.
In a specific embodiment of the invention, the material of seal nipple is PP (Polypropylene, polypropylene) material, 5VA
The mixture of fire proofing material and the weather-proof raw material of AR so that whole part can play fire prevention, age inhibiting effect.
The invention also discloses a kind of air-conditioner outdoor unit, including seal nipple disclosed in above-described embodiment, therefore have concurrently
All technique effects of embodiment are stated, are repeated no more herein.
The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or using the present invention.
