Embodiment
For the defect that prior art exists, to be described in further detail of the present utility model below in conjunction with accompanying drawing for the ease of it will be appreciated by those skilled in the art that:
The utility model provides a kind of substation breakers terminal box hermetically-sealed construction, the ethylene propylene diene rubber (EDPM) adopting the reclaimed rubber that undopes is main material, ensureing under good insulation property prerequisite, the resistance to weather performance that ethylene propylene diene rubber is good and impact elasticity can cooperatively interact with hermetically-sealed construction of the present utility model, and sealing property is further enhanced.
embodiment 1
Hermetically-sealed construction of the present utility model as shown in Figure 1, comprises sealing frame 1 and sealing plate 3; Two sidewalls 12 that sealing frame 1 comprises base portion 11 and extended into by base portion 11; Clip slot is formed between sidewall 12.Sealing frame 1 is the annular adapted with chamber door, and the sidewall 12 near sealing frame 1 center is connected with sealing plate 3; Sealing frame 1 is one-body molded with sealing plate 3, realizes seamless link, ensure that the seal of hermetically-sealed construction.In the present embodiment; sealing frame 1 section becomes " U " type; " U " type opening is slightly less than the thickness of stainless steel otch; the friction between stainless steel otch and sealing frame 1 is increased further with this; reduce the momentum to base portion 11 when stainless steel otch inserts, better can protect the main material integrality of the rubber of hermetically-sealed construction.When hermetically-sealed construction of the present utility model is applied to the comparatively smooth round and smooth object of some otch, for ease of installing, also sealing frame 1 can be designed to section is " V " type that opening large inner is little.
When the utility model uses, only needs need be inserted by the side of the casing sealed, clip slot between sealing frame 1 two side 12, the clip slot clamping casing side of sealing frame 1, so, sealing frame 1 and the sealing plate 3 of integration ensure that housing interior volume and space outerpace completely cut off, and have stopped the grains of sand enter box house situation generation by the gap of chamber door.Otch is clamped by the clip slot of the present embodiment sealing frame 1, and sealing frame 1 base portion 11 props up the stainless steel otch of casing side, prevents hermetically-sealed construction damaged.Owing to not adopting bonding mode in installation process, naturally also just avoid the adhesive bond failure that environmental change causes, the phenomenon that sealing strip comes off can not occur.
embodiment 2
The hermetically-sealed construction of the present embodiment is on hermetically-sealed construction basis described by embodiment 1, and the structure for sealing frame 1 changes.
As shown in Figure 1, sealing frame 1 is the annular adapted with chamber door to the overall structure of the present embodiment, is connected with sealing plate 3 near sealing frame 1; The two is one-body molded, realizes seamless link, ensure that the seal of hermetically-sealed construction.In the present embodiment; sealing frame 1 section becomes " U " type; " U " type opening is slightly less than the thickness of stainless steel otch; the friction between stainless steel otch and sealing frame 1 is increased further with this; reduce the momentum to base portion 11 when stainless steel otch inserts, better can protect the main material integrality of the rubber of hermetically-sealed construction.When hermetically-sealed construction of the present utility model is applied to the comparatively smooth round and smooth object of some otch, for ease of installing, also sealing frame 1 can be designed to section is " V " type that opening large inner is little.
The structure of the present embodiment sealing frame 1 as shown in Figure 2, two sidewalls 12 comprising base portion 11 and extended into by base portion 11; Clip slot is formed between sidewall 12.The embedded steel disc 13 of sealing frame 1, steel disc 13 shape and sealing frame 1 shape adapt; Served as the skeleton of sealing frame 1 by steel disc 13, can not only improve with the overall construction intensity of rubber for main material, stainless steel otch more can be avoided to cut off hermetically-sealed construction.The sidewall 12 of sealing frame 1 is provided with ligulate button 14, ligulate button 14 in clip slot to be unfavorable for object exit clip slot direction extend.Ligulate button 14 is symmetricly set on the sidewall 12 of formation clip slot, and the direction extended to ligulate button 14 tip by the root of ligulate button 14 is consistent with the direction that stainless steel otch enters clip slot.Thus, exiting clip slot to make stainless steel otch then needs than making it enter the larger power of clip slot, and this structure effectively can ensure the steadiness that hermetically-sealed construction and object are installed.According to test, when needing the object of 40N-60N and hermetically-sealed construction to depart to make insertion force, required withdrawal force is then up to 120N-160N.
In Fig. 2, sealing frame 1 base portion 11 of hermetically-sealed construction is provided with sealing gasket 2; Sealing gasket 2 pairs of base portions 11 are reinforced, the auxiliary pressure from stainless steel otch born base portion 11 and be subject to.Sealing gasket 2 inside is also provided with the upper and lower hole of through hermetically-sealed construction 21.Because the door-plate of terminal box is understood generating portion deformation or upwarps under long-term harsh and unforgiving environments, therefore, for ensureing good sealing property, the section in hole 21 is circular or oval or at least pressure-bearing side is streamlined or arc.When bearing pressure, hole 21 increases the slight appropriate deformation of generation with pressure, when distress resolves, restores to the original state during 21 postscript of hole.Certainly, hole 21 can be single hole as shown in Figure 1, also can be multiple hole.
In fig. 2, the side of sealing gasket 2 load-bearing is also provided with support arm 22; Support arm 22 extends to the direction away from middle sealing gasket 2 center.When hermetically-sealed construction of the present utility model is in the operating state of pressure-bearing, as shown in Figure 2, sealing gasket 2 is in artesian condition, different deformation is there is in hole 21 along with pressure is different, even if door-plate generation deformation, also ensure that sealing gasket 2 and body surface fit tightly all the time, improve sealing property.Now, support arm 22 oblique, in by the body surface sealed, assists the pressure bearing sealing gasket 2 on the one hand, and the sealing property avoiding the too much fatigue of material deformation to cause declines; On the other hand, support arm 22 can also stop and is deposited in supporting pad 2 surface by the grains of sand etc. (the too much grains of sand are piled up and the strong point 2 can be caused surperficial and can not be fitted tightly by sealed object surface with the fine gap formed by the body surface sealed, reduce sealing property), thus also just improve the result of use of sealing structure in the larger area, outdoor of dust storm.Sealing frame 1 and sealing gasket 2 are formed in one, and are convenient to produce and install and use.
To sum up, the utility model adopts sealing frame 1 to be clamped by otch, and sealing frame 1 base portion 11 props up stainless steel otch, prevents hermetically-sealed construction damaged, ensure that sealing effectiveness; Sealing gasket 2 is abundant compared with sealing strip, add the thickness of sealing frame 1 base portion 11, hole 21 on fitted seal pad 2 and support arm 22, effectively prevent the partial aperture that chamber door deformation produces, substantially increase sealing property, avoid " laying dust phenomenon " that existing terminal box often has, eliminate time and the operation of labor cleaning.
In addition, hermetically-sealed construction does not adopt bonding mode, naturally also just avoids the adhesive bond failure that environmental change causes.
The above embodiment only have expressed execution mode of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.
