The wire outlet structure has the advantages that the wire outlet structure is excellent in sealing performance after a wire is mounted, and the rubber ring in the wire outlet structure is easy to replace.

Description

Wire outlet hole structure for combustion gas test terminal
Technical field
The invention belongs to explosion-proof field, particularly relate to a kind of wire outlet hole structure for combustion gas test terminal.
Background technique
Combustion gas test terminal is for sending to far-end, and the signal that receives far-end, be arranged on gas monitoring station, it is connected with the various monitoring instruments in monitoring station, because near gas pipeline, so pay much attention to explosion-proof, special line place, if gas leakage enters in the housing of test terminal, easily there is explosive incident, so occur that place, hole need to seal setting, existing method is only that a circumferential groove is set in hole, in circumferential groove, snap in rubber ring, but such sealing effect is not very good, use long afterwards, rubber ring is rubbed too much, lost sealability, and be also difficult to change after rubber ring damage.
Summary of the invention
Object of the present invention is to overcome the deficiency of present technology, and a kind of wire outlet hole structure for combustion gas test terminal is provided, and solves existing combustion gas test terminal wire outlet hole sealing effect bad, not easily changeable defect after inner rubber ring damages.
The present invention is achieved through the following technical solutions: for the wire outlet hole structure of combustion gas test terminal, comprise the wire outlet hole that runs through wall box, described wire outlet hole is shoulder hole, wire outlet hole is macropore near the one end outside casing, near the one end in casing, it is aperture, in macropore, be provided with rubber ring and compressing rotating part, compressing rotating part is threaded in macropore, compressing rotating part is provided with the coaxial aperture coordinating with aperture, the external diameter of rubber ring is consistent with the diameter of macropore, and the internal diameter of rubber ring is consistent with the diameter of aperture.In this device, wire outlet hole is for the turnover of cable, cable and wire outlet hole should be supporting, the diameter of cable equals the diameter of aperture, coaxial aperture is consistent with compressing rotating part axis, during use, cable is through wire outlet hole, rubber ring and compressing rotating part, rubber ring is positioned at macropore, rotation compressing rotating part, rubber ring is oppressed, make the rubber ring horizontal expansion of having to, thereby cable is carried out to a circle compressing, guaranteed sealing, and while needing high leak tightness, rubber ring thickness is increased, and rubber ring oppressive force is also increased, thereby strengthened sealing, and the very convenient replacing of rubber ring in this device.
Further, above-mentioned compressing rotating part is a hex head bolt that is provided with coaxial aperture, can tighten compressing rotating part with pliers, guarantees sealing.
Further, the length of threaded end and the length of macropore of above-mentioned compressing rotating part coordinate, and the hexagonal end of compressing rotating part is that rubber is made, when threaded end is urged to rubber ring, hexagonal end also can be urged to aperture, thereby makes the also horizontal expansion of hexagonal end, cable is oppressed, carry out first layer sealing.
Further, the periphery of above-mentioned hexagonal end is covered with the raised line having vertically, because be that rubber is made, so with the bad rotation of pliers, so raised line is set, increase frictional force, facilitates staff to rotate compressing rotating part.
The invention has the beneficial effects as follows: the wire outlet hole structure of this device, after installing cable, sealability is fine, and inner rubber ring is easily changed.

Fig. 2 is the structural representation of compressing rotating part;
In figure, 1-casing, 2-wire outlet hole, 3-rubber ring, 4-oppresses rotating part, 201-macropore, 202-aperture, 401-coaxial aperture, 402-threaded end, 403-hexagonal end, 404-raised line.
Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, but structure of the present invention is not limited only to following examples:
[embodiment]
As shown in Figure 1, 2, wire outlet hole structure for combustion gas test terminal, comprise the wire outlet hole 2 that runs through casing 1 sidewall, described wire outlet hole 2 is shoulder hole, wire outlet hole 2 is macropore 201 near the one end outside casing 1, near the one end in casing 1, it is aperture 202, in macropore 201, be provided with rubber ring 3 and compressing rotating part 4, compressing rotating part 4 is threaded in macropore 201, compressing rotating part 4 is provided with the coaxial aperture 401 coordinating with aperture 202, the external diameter of rubber ring 3 is consistent with the diameter of macropore 202, and the internal diameter of rubber ring 3 is consistent with the diameter of aperture 201.In this device, wire outlet hole 2 is for the turnover of cable, cable and wire outlet hole 2 should be supporting, the diameter of cable equals the diameter of aperture 202, during use, cable is through wire outlet hole 2, rubber ring 3 and compressing rotating part 4, rubber ring 3 is positioned at macropore 201, rotation compressing rotating part 4, rubber ring 3 is oppressed, make rubber ring 3 horizontal expansion of having to, thereby cable is carried out to a circle compressing, guaranteed sealing, and while needing high leak tightness, rubber ring 3 thickness are increased, and rubber ring 3 oppressive forces are also increased, thereby strengthened sealing, and the very convenient replacing of rubber ring 3 in this device.
In the present embodiment, oppressing rotating part 4 is a hex head bolt that is provided with coaxial aperture 401, can tighten compressing rotating part 4 with pliers, guarantees sealing.
The length of oppressing the threaded end 402 of rotating part 4 in the present embodiment coordinates with the length of macropore 201, the hexagonal end 403 of compressing rotating part 4 is made for rubber, when threaded end 402 is urged to rubber ring 3, hexagonal end 403 also can be urged to aperture, thereby make also horizontal expansion of hexagonal end 403, cable is oppressed, carry out first layer sealing.
In the present embodiment, the periphery of hexagonal end 403 is covered with the raised line 404 having vertically, because be that rubber is made, so with the bad rotation of pliers, so raised line 404 is set, increase frictional force, facilitates staff to rotate compressing rotating part 4.
