Abstract
The invention discloses and disclose a kind of collision mat, it is characterised in that including rubber blanket and rustless steel pad, the inwall of rubber blanket is provided with the terraced steps that single track matches with screw thread on bolt；Rustless steel pad is located between rubber blanket and bolt, and the outer rim of rustless steel pad extends along the outer wall of rubber blanket to the end face of flange.The present invention is prevented from water and enters inside insulating basin bolt hole；After bolt fastening, the paint of flange surface can be wiped off by collision mat section, makes bolt and flange contact reliable, prevents bolt unsettled, and switching manipulation produces switching overvoltage and makes bolt head electric discharge phenomena.
Description
Technical field
The present invention relates to a kind of collision mat, be specifically related to a kind of for adpting flange, insulating basin bolts at two ends waterproof
Packing ring, belongs to outdoor GIS product technical field.
Background technology
GIS product there are the insulating basin supporting conductor, outdoor product rain or after lower snow melt, water can be along spiral shell
Stricture of vagina enters in the bolt hole of insulating basin, and after northerly winter, water freezing expanded, insulating basin bolt hole is split up stricture of vagina by meeting, leads
Cause product leaks gas, and insulation effect declines, and even causes GIS to produce failure accident.Existing insulating basin waterproof construction uses routine
Plain washer, it is enclosed within outside bolt, forms waterproof construction after bolt is tightened and between flange.Conventional plain washer cannot prevent water
Divide and enter inside bolt hole.Owing to flange surface has paint, common plain washer and flange contact are bad, and GIS product is being kept apart
The electric discharge of switching overvoltage bolt is easily produced during pass deciliter.
Summary of the invention
Problem to be solved by this invention is that after outdoor GIS product rains or snows after using collision mat, water is easily accessible
In insulating basin bolt hole.
In order to solve the problems referred to above, the invention provides a kind of collision mat, it is characterised in that include rubber blanket and rustless steel
Pad, the inwall of rubber blanket is provided with the terraced steps that single track matches with screw thread on bolt；Rustless steel pad is located at rubber blanket and bolt
Between, the outer rim of rustless steel pad extends along the outer wall of rubber blanket to the end face of flange.
Preferably, upper and lower two outer rims of described rubber blanket are cylindrical chamfering structure.
Preferably, between described rubber blanket and rustless steel pad it is interference fit.
Preferably, described rustless steel pad contacts with the end face of flange.Common plain washer and flange contact are bad.Use punching press
After the fastening of rustless steel pad, the paint on end face of flange can be wiped off, make spacer for bolt contact good.
Preferably, described rubber blanket wall rustless steel thick 25%～30%.
The hole of fitted bolt specification it is provided with in the middle of rubber blanket, rustless steel pad.
Compared with prior art, the beneficial effects of the present invention is:
1, collision mat of the present invention is prevented from inside water entrance insulating basin bolt hole；
2, after bolt fastening, the paint of flange surface can be wiped off by collision mat section, makes bolt and flange contact reliable, anti-
Only unsettled bolt produces switching overvoltage, bolt head electric discharge phenomena when switching manipulation.
Accompanying drawing explanation
Fig. 1 is the sectional view of rubber blanket；
Fig. 2 is the sectional view of rustless steel pad；
The assembling schematic diagram of the collision mat that Fig. 3 provides for the present invention.
Detailed description of the invention
For making the present invention become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment
As Figure 1-3, the structural representation of a kind of collision mat provided for the present invention, it includes rubber blanket 1 and stainless
Steel pad 2.About 1 two outer rim of rubber blanket is cylindrical chamfering structure 1-1, and inwall is provided with trapezoidal with what screw thread on bolt 3 matched
Step 1-2.The cross section of rustless steel pad 2 is U-shaped.
During use, as it is shown on figure 3, rubber blanket 1 to be loaded the inner side of rustless steel pad 2, then bolt 3 is inserted rubber blanket 1
Connect with the Kong Houyu flange 4 in rustless steel pad 2.The outer wall of rubber blanket 1 is interference fit with the inwall of rustless steel pad 2, stainless
The lower surface of steel pad 2 and the end face 4-1 distance H ＞ 0 of flange 4.After bolt 3 is tightened, the lower surface of rustless steel pad 2 and flange 4
The decrement of end face 4-1 distance H makes rubber blanket 1 can effectively prevent moisture from entering with the contact surface A of flange 4 end face, bolt 3
After assembling, terraced steps 1-2 of rubber blanket 1 is embedded into the Bottom of Thread of bolt 3, and terraced steps 1-2 contacts with bolt 3 screw thread
Face B can prevent moisture from entering further.
