Abstract
The invention discloses a kind of trench cover plate handle aperture dust plugs, including dust cap and be integrally formed the dust cap back side cock body, the dust-proof cap surface is plane, it is embedded with steel plate, integrally formed with mounting ring, the cock body is looped around on the outside of mounting ring at the back side, and has arc boss on the outer wall of cock body upper end, dust plug is inlaid in handle aperture, is limited by arc boss.The present invention provides a kind of trench cover plate handle aperture dust plug, by optimizing cock body structure, cooperates its quick plug of embedded high-speed double electromagnet, promotes the convenience used.
Description
Technical field
The present invention relates to a kind of dust plug more particularly to a kind of trench cover plate handle aperture dust plugs.
Background technique
In conference and exhibition center, trench usually can be all set to arrange booth case, powered to realize to exhibition position each in exhibition,
Booth case is typically mounted in trench, while each cabling is also in trench, and trench cover plate can be all arranged in trench surface
It is protected, in order to facilitate the pick-and-place of trench cover plate, all one or more handle apertures can be set on its surface, cooperate lifting tool
Lifted opening (reason as inspection well cover).
Due to being all this electrical equipment of booth case being arranged in trench in exhibition, so without hope there is foreign matter or excessively
Dust fall into and (can have many dusts and foreign matter in exhibition), while this handle aperture can also exist heel of high-heel shoe step on into
The danger gone in order to reduce the generation of such case requires that some dust plugs are arranged in these handle apertures.
Generally stretching structure is arranged on its surface in existing dust-proof plug structure, is conveniently pulled out, and this structure is used in
It is that not applicable, raised stretching structure will cause impede when in use on trench cover plate, to influence personal safety, also there is one
The dust plug for planting not stretching structure, needs personnel to push aside from side when extracted, and use is very inconvenient, and is easy
Now take off bad situation.
Summary of the invention
It is an object of the invention to overcome the deficiencies of existing technologies, a kind of trench cover plate handle aperture dust plug is provided, is led to
Optimization cock body structure is crossed, cooperates its quick plug of embedded high-speed double electromagnet, promotes the convenience used.
To achieve the above object, the following technical solutions are proposed: a kind of trench cover plate handle aperture dust plug by the present invention, including
In the cock body at the dust cap back side, the dust-proof cap surface is plane, is embedded with a steel plate, the back side one for dust cap and integrated molding
Body formed to have mounting ring, the cock body is looped around on the outside of mounting ring, and has arc boss, dust plug on the outer wall of cock body upper end
It is inlaid in handle aperture, is limited by arc boss.
Preferably, the cock body quantity be it is multiple, spacer ring is located on the outside of mounting ring, and between cock body between be divided into 3 ~
4mm, it is ensured that distending power when plug.
Preferably, the cock body is looped around on the outside of mounting ring, highly than for 4:1 between height and mounting ring.
Preferably, the outside diameter that the cock body is formed is consistent with handle bore dia, and the outer circle that arc boss is formed
Diameter is greater than handle bore dia 1mm.
Preferably, the radian of the arc boss is R2, smoothness when plug is promoted.
Compared with prior art, disclosed a kind of trench cover plate handle aperture dust plug has following beneficial
Effect:
It is embedded in a sheet metal in dust-proof cap surface, this structure design cooperated magnet when needing to extract dust plug
The extraction of dust plug can be realized in suction, has not both needed that stretching structure is arranged in dust-proof cap surface, has not also needed to push aside, reduce
The difficulty that dust plug takes out improves its service life, and there is no external dangerous hidden danger；
For the structure of cock body, the height of cock body is lengthened, the specific size of space and surface arc boss are cooperated, it can be with
Ensure the smoothness and distending power when plugging, prevents it because clamping degree not enough falls off.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is another visual angle figure of the invention；
Fig. 3 is side view of the invention.
Specific embodiment
Below in conjunction with attached drawing of the invention, clear, complete description is carried out to the technical solution of the embodiment of the present invention.
As shown in Fig. 1 ~ 3, a kind of disclosed trench cover plate handle aperture dust plug is rubber material, packet
It includes dust cap 1 and is integrally formed the cock body 2 at the dust cap back side, the dust-proof cap surface is plane, and embeds one on surface
A sheet metal 5, the back side is integrally formed with mounting ring 3, when extraction, attracts dust-proof cap surface can be by dust plug by magnet
It is whole to extract.
The cock body quantity be it is multiple, interval is looped around on the outside of mounting ring, and controlling the interval a between cock body is 3 ~ 4mm, plug
Height ratio between body height and mounting ring is 4:1, it can be ensured that cooperation interval in upper part has certain distending when drawing
Power promotes the smoothness of plug, and arc boss 4 is arranged outside cock body upper end, radian R2, and arc boss formation
Outside diameter is greater than handle bore dia 1mm, and the outside diameter that cock body is formed is consistent with handle bore dia, the control of these sizes
It may insure in the firm embedded handle aperture of cock body, and extraction that also can be smooth when drawing.
Technology contents and technical characteristic of the invention have revealed that as above, however those skilled in the art still may base
Make various replacements and modification without departing substantially from spirit of that invention, therefore, the scope of the present invention in teachings of the present invention and announcement
It should be not limited to the revealed content of embodiment, and should include various without departing substantially from replacement and modification of the invention, and be this patent Shen
Please claim covered.
