Technical Field

The invention relates to municipal equipment, in particular to a protective warning fence for municipal construction.

Background

Various public infrastructure construction supporting urban life belongs to municipal engineering categories, such as common urban roads, bridges and subways, and various pipelines closely related to life: rainwater, sewage, water supply, reclaimed water, electric power (parts except red lines), telecommunication, heating power, gas and the like, and construction of squares, urban greening and the like belong to the municipal engineering category.

Have certain potential safety hazard when carrying out municipal construction, consequently need avoid idle miscellaneous people etc. to get into the construction place. Chinese patent (grant No. CN 207376512U) discloses a warning device for municipal construction, which comprises a placing box, wherein the opening of the placing box is upward, a supporting plate is arranged in the placing box, a warning board is arranged on the supporting plate, and a driving part for driving the supporting plate to vertically move upward and making the warning board stretch out of the opening of the placing box is arranged on the placing box, and the warning device has the advantages that: the warning board can be put into and place the box in, has reduced and has placed the box and cause the condition of damage to the warning board in transportation and carrying process.

The device is for removing warning device, and the structure is complicated relatively, though can avoid the warning sign to damage, but the device is not convenient enough in the in-service use process, and whole volume is great, is difficult to the wide application.

Disclosure of Invention

The invention aims to provide a protective warning fence for municipal construction, which aims to solve the problems in the background technology.

In order to achieve the purpose, the invention provides the following technical scheme:

the utility model provides a municipal construction is with protection warning fence, includes the vertical pole setting of a plurality of roots, and vertical pole setting bottom is rotated through the fixed block and is connected with cross bar group, and cross bar group top rotates with the slip cap respectively and is connected, slip cap and vertical pole setting sliding connection, one of them slip cap rear side threaded connection has tightly decides the bolt, tightly decides the bolt and runs through the slip cap and cooperate with vertical pole setting, middle part vertical pole setting top outside fixedly connected with warning banner, warning banner outer end cooperatees with the vertical pole setting in the outside.

As a further scheme of the invention: the middle part the equal fixedly connected with universal wheel of cross rod group bottom, both ends cross rod group bottom fixedly connected with vertical vaulting pole.

As a still further scheme of the invention: the fastening bolt is fixed on any one of the sliding sleeves at the two ends.

As a still further scheme of the invention: the middle part the slip cap front side is opened and is equipped with the opening, and the vertical pole setting front side in middle part is through vertical fixed connecting rod fixedly connected with automatic flexible spool, and warning banner inner is connected with automatic flexible spool, and the equal fixedly connected with couple in warning banner outer end.

As a still further scheme of the invention: the fastening bolt is a butterfly bolt.

As a still further scheme of the invention: and anti-skid grains are arranged on the outer side of the longitudinal upright rod.

As a still further scheme of the invention: the width of the longitudinal upright stanchion is less than that of the gap.

As a still further scheme of the invention: the vertical upright posts are five.

As a still further scheme of the invention: the top of the longitudinal upright stanchion is fixedly connected with an anti-climbing tip.

Compared with the prior art, the invention has the beneficial effects that: the novel safety helmet is simple in structure and convenient to use, can play a warning role during use, avoids irrelevant people from crossing the device, meanwhile, adopts the warning banner for warning, effectively avoids safety accidents, can be folded in a retractable mode, greatly reduces occupied space when not in use, and is worthy of popularization.
