Abstract

The utility model relates to a right angle type screw-free fastener, which is capable of effectively solving the problems of insecurity, inability of fast dismounting and inability of improving working efficiency which are all caused by loosening of an erected scaffold. The technical scheme is that the right angle type screw-free fastener comprises two embrace bodies fixed together perpendicularly in intersection mode. One ends of the embrace bodies are provided with fastening tiles through rotating shafts, and the other ends of the embrace bodies are provided with pull rods. One ends of the pull rods are fixed on the embrace bodies, and the other ends of the pull rods penetrate through the fastening tiles. The end portions of the pull rods penetrating through the fastening tiles are provided with pull rod caps, and tenon-shaped pins are arranged on the pull rods. The right angle type screw-free fastener is simple in structure, novel, unique, convenient to use, easy to dismount, high in working efficiency and safe and is an innovation of a building member.

Description

Right-angle type does not have the screw fastener

Technical field

The utility model relates to building field, and particularly building trade is set up a kind of right-angle type that scaffold uses does not have the screw fastener.

Background technology

Use fastener to set up scaffold in the building and be absolutely necessary, setting up the fastener that scaffold uses at present is to adopt two bolt and nuts fastening, and this structure is because pretightning force is quantitative; Receive that mechanical shock is loosening with naturally, glide easily that careful screw thread is arranged again on the bolt and nut; Mortar falls to amassing and corrosion, and it can't be installed and removed, and only damagingly removes it; Make it to scrap, need again before each the repeated use to embathe, change a silk rolling again with kerosene; Reconfigure the bolt and nut of scrapping or losing, increased a large amount of repetition acquisition expenses, increased building costs.

Summary of the invention

To above-mentioned situation, for overcoming the defective of prior art, the purpose of the utility model just provides a kind of right-angle type does not have the screw fastener, can effectively solve to set up loosening cause dangerous of scaffold and can not quickly dismantled and the problem of increasing work efficiency.

The technical scheme of its solution is to comprise and embrace body that two armfuls of body square crossings are fixed together; Embrace body one end and button watt is housed through axis of rotation; The other end of embracing body is equipped with pull bar, and an end of pull bar is fixed on to be embraced on the body, and the other end passes button watt; Pull bar pass the button watt the end on the pull bar cap is arranged, wedge pin is arranged on the pull bar.

The utility model is simple in structure, and novel unique, easy to use, easy to assemble, high efficiency, safety are the innovations on the building unit.

The specific embodiment

Explain further details below in conjunction with the specific embodiment of accompanying drawing to the utility model.

Provided by Fig. 1 to Fig. 3, the utility model comprises embraces body, embraces body 1 square crossing for two and is fixed together; Embrace body 1 one ends and button watts 3 is housed through axis of rotation 2; The other end of embracing body 1 is equipped with pull bar 4, and an end of pull bar 4 is fixed on to be embraced on the body 1, and the other end passes button watts 3; Pull bar 4 passes on the end of button watts 3 has pull bar cap 5, and wedge pin 6 is arranged on the pull bar 4.

In order to guarantee result of use, the chute 7 of said wedge pin 6 in it is sleeved on the pull bar 4.

The utility model inserts one of them with vertical two scaffolding steel pipes and embraces in the bodies 1 in use, and an end of pull bar 4 places in the button watts 3; Make button watts 3 and embrace body 1 steel pipe is embraced, tool using beats wedge pin 6 then, wedge pin 6 stretching pull bars 4; And then steel pipe is fixed on embraces body 1 and buckle in watts 3, and then two steel pipes of level are inserted other one group buckle watt and embrace in the body, repeat top operation; Two steel pipes of horizontal scaffold are fixed together, when needs are dismantled, strike loose wedge pin 6 and get final product; Convenient to use, compared with prior art, have following advantage:

1, the utility model wide application can be effective in the building of every profession and trade;

2, effect is high, and is safe in utilization, dismounting speed is fast, high efficiency;

3, simple to operate, avoided the trouble of frequent demounting bolt nut, labour intensity is little;

4, sturdy and durable, the life-span is long, can reuse for a long time, practices thrift building costs, and economic and social benefit is remarkable.
