Abstract
A kind of anti-dropping screw plug of amplifier detection mouth, belongs to TV and mechanics of communication.It is arranged in amplifier detection mouth, including the connection sheet in the screw of plug screw tail end face is fastened on externally threaded plug screw, with screw.Connection sheet is T-shaped, and the perpendicular end of T-shaped connection sheet is with the hole so as to being fixed on plug screw.Horizontal symmetrical, the diameter of its length more than detection mouth of T-shaped connection sheet.The head of plug screw is outer-hexagonal shape.Set is filled with seal washer on plug screw.It carries connection sheet, even if will not also be fallen down after taking plug screw apart, and does not influence detection.Can prevent the plug screw being removed from being dropped from eminence, it is very convenient during detection.It can be widely applied in various amplifiers.
Description
Technical field
The invention belongs to TV and communication technique field, the anti-dropping screw plug more particularly to amplifier detection mouth sets
Meter.
Background technology
Amplifier can be the amplifier for amplifying upward signal and downstream signal on same path.It is used for television transmission and
In communication system, control tower, the line bar equal-height position of outdoor transmissions circuit are often installed in.To prevent outdoor from exposing to the sun and rain dust storm frost mist
Long-term corrosion and baneful influence, shell for sealing.For ease of its inner workings of on-line checking, cover leave in band thereon
The detection mouth of screw thread.Under normal circumstances, detection mouth is fastened with plug screw and blocked.When needing detection, plug screw is torn open with spanner or spiral shell knife
Under, you can stretched into test bar and detected.After detection is finished, then by plug screw fastening thereon.
Traditional plug screw is ordinary construction, and amplifier is installed on outdoor eminence again, and plug screw is easy to from eminence after being removed
Fall down.Pick up and send back to again eminence and be also not easy to.Therefore made troubles to testing staff, it is very inconvenient.
The content of the invention
A kind of purpose of the present invention, in that overcome disadvantages mentioned above and deficiency, there is provided anti-dropping screw plug of amplifier detection mouth.
It carries connection sheet, even if will not also be fallen down after taking plug screw apart, and does not influence detection.The plug screw that is removed from eminence can be prevented
Drop, it is very convenient.
In order to achieve the above object, the present invention is arranged in amplifier detection mouth, including with externally threaded plug screw, with spiral shell
Nail is fastened on the connection sheet in the screw of plug screw tail end face.Connection sheet is T-shaped, the perpendicular end band of T-shaped connection sheet
There is the hole so as to being fixed on plug screw.Horizontal symmetrical, the diameter of its length more than detection mouth of T-shaped connection sheet.This chi
It is very little to will not fall off when may insure that plug screw is backed out from detection mouth.
The head of plug screw is outer-hexagonal shape.Set is filled with seal washer on plug screw, it is ensured that tighten the sealing of rear amplifier
And weather resistance.
Task of the invention is so completed.
The present invention carries connection sheet, even if will not also be fallen down after taking plug screw apart, and does not influence detection.Can prevent from being removed
Plug screw dropped from eminence, it is very convenient during detection.It can be widely applied in various amplifiers.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is its stereogram, but removes seal washer.
Fig. 3 is the schematic diagram after its installation, but removes 3 anti-dropping screw plugs.
Specific embodiment
Embodiment 1.A kind of anti-dropping screw plug of amplifier detection mouth, as shown in FIG. 1 to 3.It is arranged on lid 1 on amplifier
Detection mouth 2 in.The connection in the screw of the tail end face of plug screw 4 is fastened on including the plug screw 4 with external screw thread 3, with screw 5
Piece 7.Connection sheet 7 is T-shaped, T-shaped connection sheet 7 perpendicular 8 end with the hole 9 so as to being fixed on plug screw.T-shaped
Horizontal the 10 of connection sheet 7 are symmetrical, diameter of its length more than detection mouth 2.This size may insure plug screw 4 from detection mouth 2
In will not fall off when backing out.
The head 6 of plug screw 4 is outer-hexagonal shape.Set is filled with seal washer 11 on plug screw 4, it is ensured that be tightened on amplifier
Sealing afterwards and weather resistance.
Embodiment 1 carries connection sheet, even if will not also be fallen down after taking plug screw apart, and does not influence detection.Can prevent from being split
Under plug screw dropped from eminence, it is very convenient during detection.It can be widely applied in various amplifiers.
