Municipal road maintenance warning sign board

Abstract

The invention discloses a municipal road maintenance warning sign board which comprises a fixing base. The fixing base is of a hollow structure, a motor base is fixedly connected with the center of the inside of the fixing base, a motor is fixedly connected with the upper side of the motor base, a cam is fixedly connected with an output end of the motor, guide seats are symmetrically fixedly connected with the lower side of the inside of the fixing base in the left-right directions, horizontal transmission rods are slidably connected into the guide seats, transmission pressure plates are fixedly connected with the inner sides of the horizontal transmission rods, longitudinal mounting plates are fixedly connected with the outer sides of the horizontal transmission rods, and first springs are fixedly connected with the outer sides of the longitudinal mounting plates. Compared with the prior art, the municipal road maintenance warning sign board has the advantages that the municipal roadmaintenance warning sign board is simple in structure and convenient to use and can be used for municipal engineering warning; the municipal road maintenance warning sign board has warning functions,and warning effects can be improved by the municipal road maintenance warning sign board in movement modes; powered conductors are intermittently exposed, accordingly, personnel can be prevented fromclimbing over warning boards, and the municipal road maintenance warning sign board is worthy of being popularized.

Description

technical field [0001] The invention relates to a warning sign, in particular to a municipal road maintenance warning sign. Background technique [0002] Municipal engineering refers to the construction of municipal facilities. In my country, municipal facilities refer to various buildings, structures, equipment, etc. that are set up within the planning and construction scope of urban areas, towns (townships), and provide residents with paid or unpaid public products and services based on government responsibilities and obligations. The construction of various public infrastructure supporting urban life belongs to the category of municipal engineering, such as common urban roads, bridges, subways, such as various pipelines closely related to life: rainwater, sewage, water supply, reclaimed water, electricity (outside the red line) Partial), telecommunications, heat, gas, etc., as well as the construction of squares, urban greening, etc., all belong to the category of munici...

Problems solved by technology

[0003] Municipal engineering also includes the maintenance of some damaged municipal facilities. When repairing these facilities, it is not only necessary to ensure the safety of construction personnel, but also the safety of passers-by, so as to prevent passers-by from being sent to Shanghai due to construction. Therefore, warning signs are required to warn passers-by. Warning, avoid passers-by approaching, the existing signs or other indicating devices mostly use static indications when indicating, and the indication effect is not good
