Abstract
The utility model discloses a manhole cover plate for a signal tower. The manhole cover plate for the signal tower comprises a round cover plate main body, wherein the edge of the cover plate main body is provided with a pair of connection beams between which a spring shaft barrel is arranged; the spring shaft barrel is provided with a rotatable buffering part which comprises a buffering arc plate; the two sides of the buffering arc plate are respectively provided with a buffering camber beam; a joint pin shaft is arranged between the buffering camber beams; and the joint pin shaft penetrates through the spring shaft barrel. According to the manhole cover plate for the signal tower, by utilizing the rotatable buffering part arranged at the spring shaft barrel, when a user closing the cover plate, the impact force of the cover plate can be greatly reduced, the collision noise is greatly reduced, and the working comfort level of workers is improved. The manhole cover plate for the signal tower is reasonable in structure, low in cost and convenient in use.
Description
Technical field
The utility model relates to a kind of communication device, or rather, is a kind of cover plate for manhole for signal tower.
Background technology
The cover plate for manhole of existing signal tower lacks buffering when closing, and easily produces larger noise, and the phenomenon that also often bumps, and affects constructor's normal operation.
Summary of the invention
The utility model mainly is to solve the existing technical problem of prior art, thereby a kind of cover plate for manhole for signal tower is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of cover plate for manhole for signal tower, described cover plate for manhole for signal tower comprises the cover plate main body of a circle, the edge of described cover plate main body is provided with a pair of connecting cross beam, be provided with a spring beam barrel between the described connecting cross beam, described spring beam barrel is provided with a rotating buffer part, described buffer part comprises a buffering arc plate, the both sides of described buffering arc plate are respectively equipped with a buffering camber beam, be provided with one between the described buffering camber beam and connect bearing pin, described connection bearing pin runs through described spring beam barrel.
As the utility model preferred embodiment, the inner surface of described buffering arc plate is provided with rubber layer.
Cover plate for manhole utilization for signal tower of the present utility model is arranged on the rotating buffer part of spring beam barrel, and the user can slow down the impact force of cover plate greatly when closing cover plate, greatly reduce collision noise, has improved the comfort level of workman's work.The manhole cover plate structure that should be used for signal tower is reasonable, with low cost, easy to use.
