Description
Technical field
The present invention relates to building implement technical fields, more specifically, it relates to a kind of foot with wear-and corrosion-resistant coating
Hand cradle.
Background technology
Scaffold is the various holders set up at the construction field (site) for operation and high-rise working, is the logical of building field
With term, it is mainly used in exterior wall, interior decoration or the higher place that can not directly construct of floor height on building sites.
Currently, used scaffold is made of using tube material mostly, this is because steel strength is high, durability
Good, service life is long, thus receives the favor of workpeople.However used in the natural environment since scaffold is exposed for a long time, by
To expose to the weather, sleet is drenched without any safeguard measure so that scaffold is easily corroded, and scaffold, which is corroded, can make foot
The bearing capacity of hand cradle substantially reduces, and in addition during scaffold long term wear, can make the company between steel pipe and connection card
Receive influence, junction is easy active, these can all operate on scaffold to worker and bring security risk, the use of scaffold
Service life also has a greatly reduced quality.It thus needs to coat last layer wear-and corrosion-resistant coating in the outer surface of scaffold, to prevent scaffold
It excessive wear and is corroded, to improve the service life of scaffold.
In addition the assembly connection mode of existing scaffold is all that terminal pad coordinates with buckle structure, is arranged in terminal pad
There is a connecting hole, it is corresponding on buckle structure to be also equipped with perforation, buckle structure is caught in terminal pad so that on buckle structure
Perforation it is corresponding with the connecting hole in terminal pad, then toward perforation in be inserted into fixed block come realize scaffold assembly clamping, this
The assembly connection mode of sample is cumbersome, takes time and effort.
Invention content
The object of the present invention is to provide a kind of scaffolds with wear-and corrosion-resistant coating that can realize quick assembling connection.
To achieve the above object, it is realized by following technological means:
A kind of scaffold with wear-and corrosion-resistant coating, including several montants being vertically arranged and be connected between montant
Connecting rod, the terminal pad for being connected to connecting rod on montant is provided on montant, several companies are provided in terminal pad
Hole is connect, the buckle structure being fixed on connecting rod in terminal pad is additionally provided in the end of connecting rod, the buckle structure includes
The button body of two vertical spacings setting, the consistency of thickness of the spacing and terminal pad of two button bodies, the opposite face for detaining body are additionally provided with block tongue,
Offer an accommodating cavity in button body opposite face, block tongue by an extensible member slip in accommodating cavity, when block tongue stretches out accommodating cavity
When outer, just it is caught in connecting hole.
Through the above technical solutions, buckle structure includes button body and block tongue, block tongue is scalable in button body, when needing to assemble
When scaffold, button body is caught in terminal pad, flexible block tongue makes block tongue be caught in the connecting hole of terminal pad, you can realize to foot hand
The assembly of frame, and block tongue it is flexible by switch automatically control, assemble up in this way it is simple and convenient, it is easy to operate.
Advanced optimize for:The extensible member includes the spring between an electromagnet and connection electromagnet and block tongue, institute
State electromagnet dead electricity is controlled by the control module of a switching circuit, when electromagnet obtains it is electric when, block tongue adsorbed by electromagnet and
It shrinks in accommodating cavity, when electromagnet dead electricity, block tongue stretches out accommodating cavity under the reply force effect of spring, is stuck in connection card
On mounting hole.
Through the above technical solutions, spring connection block tongue and electromagnet, when electromagnet obtains it is electric when, block tongue is inhaled by electromagnet
Attached and shrink in accommodating cavity, when electromagnet dead electricity, block tongue stretches out accommodating cavity under the reply force effect of spring, is stuck in terminal pad
Connecting hole on.The stretching motion of block tongue is controlled with electric power, it is intelligent, simple and convenient, easy to operate.
Advanced optimize for:The block tongue is along terminal pad width radially and width of the connecting hole along terminal pad radially
Unanimously.
Through the above technical solutions, what block tongue was arranged along the width of terminal pad radially is radial along terminal pad with connecting hole
On equivalent width, such block tongue cannot move left and right after being caught in connecting hole, to prevent entire buckle structure from shaking, protect
Connecting rod has been demonstrate,proved fixed to the stability on montant.
It advanced optimizes as a kind of scaffold wear-and corrosion-resistant coating, including the group of following parts by weight are grouped as:
Advanced optimize for:A kind of scaffold wear-and corrosion-resistant coating, including the group of following parts by weight are grouped as:
