A pressing nut, the pressing ring and the sealing pad are arranged in the hollow inner portion of the cover body in sequence from top to bottom. The pressing nut is inserted into the cover body from the top end of the cover body to be arranged. The sealing base is fixed at the bottom of the cover body. A steel pad is arranged between the sealing base and the sealing pad. The inner portion of the sealing base is in a hollow inverted-cone groove shape. The sealing piece matched with the sealing base is placed through the hollow inverted-cone groove shape. The pressing plate is arranged at the bottom end of the sealing piece. The fastening and sealing mechanism is arranged on the high-pressure submarine optical cable pressure-resisting test equipment in a covering mode, inner pressure is high, the sealing piece is pushed to be tightly attached at an attaching opening of the optical cable and the cover body, meanwhile, contacting of the sealing piece and the optical cable cannot cause damage of the outer layer skin of the optical cable, and the mechanism is simple in structure and convenient to operate.
Description
Technical field
The utility model relates to a kind of high pressure submarine optical fiber cable fastening and sealing mechanism for withstand voltage test equipment.
Background technique
High pressure submarine optical fiber cable withstand voltage test equipment is used for setting up a high pressure cavity volume, the working environment (35MPa) of simulated sea bottom optical cable below tens kilometers, with the properties of test optical fibre cables, because the two ends of optical cable must be drawn beyond container, sealing between optical cable and top cover is difficulty quite, the Major Difficulties of sealing is that the outer protective sleeve of optical cable is rubber material, plasticity is larger, compression is sent out in seal ring and optical cable outer ring, particularly along with the rising of internal pressure, optical cable is outwards slippage constantly, and external diameter diminishes, even break outer rubber, also cannot seal, domestic user's part adopts imported product at present, complex structure, and poor reliability, need repeatedly adjust, dismounting, outer rubber hardness requirement to optical cable is very high, cause optical cable frequent breakage and change.
Model utility content
The utility model proposes a kind of high pressure submarine optical fiber cable fastening and sealing mechanism for withstand voltage test equipment, by the structure of sealing gasket and Sealing is set on lid, guarantee that lid optical cable Sealing when this structure in the time sealing up high pressure submarine optical fiber cable withstand voltage test equipment can fully reach the function of sealing, also can not cause damage to the outer rubber of optical cable.
The utility model is specifically achieved through the following technical solutions:
A kind of high pressure submarine optical fiber cable fastening and sealing mechanism for withstand voltage test equipment, comprise hollow type lid, hold-down ring, sealing gasket, sealing seat, Sealing and pressing plate, the hollow inside of described lid is provided with gland nut, hold-down ring, sealing gasket from top to bottom successively, and described gland nut inserts lid portion inside and installs from lid top; Described lid bottom fixing seal seat, is provided with steel pad between described sealing seat and described sealing gasket; Described sealing seat inside is hollow inverted cone fluted body, and by the inner Sealing coincideing with it of placing of described hollow inverted cone fluted body, described Sealing bottom is provided with pressing plate; Described pressing plate, Sealing, sealing seat, steel pad, sealing gasket, hold-down ring and gland nut have the identical hollow type holes for optical cables of internal diameter size, and the internal diameter of described holes for optical cables equates with the external diameter of optical cable.
Further, described sealing gasket comprises D grommet type seal and V-seal pad, and described D grommet type seal and V-seal pad interval arrange at least one group;
Further, described pressing plate is arranged on the bottom of lid by screwing screw rod.
The beneficial effect that the utility model produces is: the utility model structure is added a cover on high pressure submarine optical fiber cable withstand voltage test equipment, internal pressure is higher, promote Sealing and fit tightly the laminating mouth at optical cable and lid, contact between Sealing and optical cable simultaneously can not cause the outer epidermis of optical cable to damage, and this apparatus structure is simple, easy to operate.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technological scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiments.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment who obtains under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, a kind of high pressure submarine optical fiber cable fastening and sealing mechanism for withstand voltage test equipment, comprise hollow type lid 1, gland nut 2, hold-down ring 3, sealing gasket, sealing seat 7, Sealing 8 and pressing plate 9, the hollow inside of described lid 1 is provided with gland nut 2, hold-down ring 3, sealing gasket from top to bottom successively, described sealing gasket comprises D grommet type seal 4 and V-seal pad 5, described D grommet type seal and V-seal pad interval arrange at least one group, and described compression spiral shell 2 inserts lid 1 inside from lid top; The bottom fixing seal seat of described lid 1, is provided with steel pad 6 between described sealing seat 7 and described sealing gasket; Described sealing seat 7 inside are hollow inverted cone fluted body, and by the inner Sealing coincideing with it 8 of placing of described hollow inverted cone fluted body, described Sealing 8 bottoms are provided with pressing plate 9; Described pressing plate 9, Sealing 8, sealing seat 7, steel pad 6, sealing gasket, hold-down ring 3 and gland nut 2 have the identical hollow type holes for optical cables of internal diameter size, the internal diameter of described holes for optical cables equates with the external diameter of optical cable 10, further, described pressing plate 9 is arranged on the bottom of lid 1 by screwing screw rod.
The utility model is arranged on high pressure submarine optical fiber cable withstand voltage test equipment, and conventionally the pressure in equipment is all very high, and particularly, along with the rising of internal pressure, optical cable is outwards slippage constantly, and external diameter diminishes, and even breaks outer rubber, also cannot seal.Under the project organization of this structure, internal high pressure moves to the direction of lid 1 promoting Sealing 8, and because sealing seat 7 is inverted cone, can conveniently push Sealing 8, Sealing 8, by adopting plastic material as polyurethane, so further reduces the contact gap of Sealing 8 and optical cable 10, reaches the effect of sealing, internal pressure is larger, and the more obvious obturation effect of effect of its extruding is also better.Because the hold-down ring 3 and the steel pad 6 that are positioned at sealing gasket two ends are all metal material, in the process of Sealing extruding, crush seal pad produces micro-extending amount simultaneously, and hold-down ring 3 and steel pad 6 have guaranteed balance, and it is reasonable in design, safe and reliable.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
