Description

Flat cable linear sealing box

Technical field

The utility model relates to a kind of cable outlet sealing device, is specifically related to a kind of flat cable linear sealing box.

Background technology

Chinese utility model patent (patent No. 200620044444.6) discloses one " Easy detatchable cablle tappingdevice of submersible pump shaft ", it comprises pit shaft upper cover, divide half formula caulking gum body, housing screw, pit shaft upper cover frame position is fixedly connected with first caulking gum body, semitight rubber bodies is provided with below first caulking gum body, second caulking gum body is fixed on the port of well bore wall, the end face that upper and lower semitight rubber bodies contacts has a point half formula closed hole, two and half formula caulking gum bodies are compressed by tight fixed bolt, cable passes in point half formula closed hole, two and half formula caulking gum bodies realize sealing to cable.

But, owing to adopting a point half formula sealing, caulking gum body not only can produce radial deformation when pressurized, the distortion that also can produce along cable axis because of rubber seal body deformability, the pressure that tight fixed bolt produces when routine use is fixed value, along with the growth of service time, the distortion produced in rubbery sealed body ageing process is substantially all axial deformation, when tight fixed bolt produces pressure fixing, upper-lower seal body produces slight gap because of distortion, cause leaking, if cable jacket is slightly out of shape, then having water leakage can be more serious.

Summary of the invention

The purpose of this utility model is the deficiency existed to overcome prior art, provide a kind of not only can effective sealing flat cable, but also can avoid producing because rubber bodies is aging the flat cable linear sealing box of seepage defect.

The utility model is achieved through the following technical solutions: a kind of flat cable linear sealing box, comprise sealing cassette holder, gland, sealing ring and at least two tight fixed bolts, described sealing cassette holder is provided with the installation cavity from upper surface middle part to downward-extension, described gland is connected along forming by columnar part and the annular that takes shape in columnar part upper end outer rim, described sealing ring is arranged at the bottom of described installation cavity, described columnar part stretches in described installation cavity downwards, the upper surface of described sealing ring is supported in the bottom surface of described columnar part, described annular connects the top along being positioned at described sealing cassette holder, described annular connects along being provided with pilot hole with the upper surface of described sealing cassette holder, described annular connect along with described sealing cassette holder being connected by described tight fixed bolt and pilot hole, the columnar part of described gland and the middle part of described sealing ring are all provided with corresponding to the shape of flat cable the through hole passed for flat cable.

Described sealing ring is male and fomale(M&F) sealing ring, the upper surface of this male and fomale(M&F) sealing ring is provided with the annular groove that cross section is " V " font, the lower surface of male and fomale(M&F) sealing ring is provided with the annular protrusion that cross section is " V " font, annular groove and annular protrusion stagger mutually, the annular groove that the bottom of the columnar part of described gland corresponds to male and fomale(M&F) sealing ring is provided with annular protrusion, and the annular protrusion corresponding to male and fomale(M&F) sealing ring bottom the installation cavity of described sealing cassette holder is provided with annular groove.

The bottom of described sealing cassette holder is provided with adpting flange.

The beneficial effects of the utility model are: the utility model changes the axial deformation of male and female face sealing ring into radial deformation by the pressure of gland, efficiently avoid the distortion along cable axis that in installation and long-time use procedure, male and female face sealing ring produces, sealing function of the present utility model is more excellent, it both can effective sealing flat cable, the rubber bodies because of male and female face sealing ring can be avoided again aging and produce the defect of seepage.

Accompanying drawing explanation

Fig. 1 is plan structure schematic diagram of the present utility model;

Fig. 2 is the C of Fig. 1---C to cross-sectional view;

Fig. 3 is using state structural representation of the present utility model.

In the drawings: 1-seals cassette holder; 2-gland; 3-flat cable; 4-male and fomale(M&F) sealing ring; 5-tight fixed bolt; Pump outer sleeve in 6-pipe.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in detail.

As Fig. 1, shown in Fig. 2, a kind of flat cable 3 linear sealing box, comprise sealing cassette holder 1, gland 2, sealing ring and at least two tight fixed bolts 5, sealing cassette holder 1 is provided with the installation cavity from upper surface middle part to downward-extension, gland 2 is connected along forming by columnar part and the annular that takes shape in columnar part upper end outer rim, sealing ring is arranged at the bottom of installation cavity, columnar part stretches into downwards in installation cavity, the upper surface of sealing ring is supported in the bottom surface of columnar part, annular connects the top along being positioned at sealing cassette holder 1, annular connects edge and is provided with pilot hole with the upper surface of sealing cassette holder 1, annular connect along with sealing cassette holder 1 being connected by tight fixed bolt 5 and pilot hole, the columnar part of gland 2 and the middle part of sealing ring are all provided with corresponding to the shape of flat cable 3 through hole passed for flat cable 3.
