Abstract

The utility model relates to a straight pipe type screw-free fastener which can effectively solve the problems of unsafety and inconvenience in quick disassembling and assembling due to the looseness of a built scaffold and aims at improving the working efficiency. The technical scheme for solving the problems is as follows: the straight pipe type screw-free fastener comprises a first buckle tile, a second buckle tile and a pin shaft, wherein one end of the first buckle tile and one end of the second buckle tile are connected together in a rotating manner through the pin shaft, a pull rod which is vertical to a fixed head is arranged on the fixed head at the other end of the second buckle tile, one end of the pull rod is fixed on the fixed head, the other end of the pull rod penetrates the first buckle tile, a pull rod cap is arranged at the end part of the pull rod to fix the first buckle tile and the second buckle tile together, a wedge-shaped pin is arranged on the pull rod, and a rotating body is arranged in a cavity formed between the first buckle tile and the second buckle tile. The straight pipe type screw-free fastener is simple in structure, novel, unique, fast in disassembly and assembly of the built scaffold, safe, low in labor intensity, high in working efficiency, long in service life and significant in economic and social benefits.

Description

Straight pipe 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 straight pipe 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 a bolt and nut fastening, and this structure is because pretightning force is quantitative; It is loosening with naturally to receive mechanical shock, glides easily, and 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 straight pipe type does not have the screw fastener, can solve effectively that set up scaffold loosening cause dangerous and can not quickly dismantled and the problem of increasing work efficiency.

The technical scheme of its solution is, includes first button watt, second button watt and bearing pin, and first button watt and second is detained a watt end and is rotatably connected through bearing pin; Second the button watt other end fixing head on the pull bar perpendicular to fixing head is housed, an end of pull bar is fixed on the fixing head, the other end pass first the button watt; There is the pull bar cap its end; First button watt watt is fixed together with second button, wedge pin is arranged on the pull bar, in the chamber of formation rotor is housed between first button watt and second button watt.

The utility model is simple in structure, and is novel unique, set up the scaffold demolition, installation fast, safety, labour intensity is little, high efficiency, long service life, economic and social benefit is remarkable.

The specific embodiment

Elaborate below in conjunction with the specific embodiment of accompanying drawing to the utility model.

Provide by Fig. 1 to Fig. 3; The utility model includes first button watt, second button watt and bearing pin, and first button watt 1 and second button watt 2 one ends are rotatably connected through bearing pin 3, and second detains on the fixing head 4 of watt 2 other ends pull bar 5 perpendicular to fixing head is housed; One end of pull bar 5 is fixed on the fixing head 4; The other end passes first button watt 1, and there is pull bar cap 6 its end, first button watt and second is detained watt be fixed together; There is wedge pin 7, the first to detain in watt chamber of 1 and second button watt 2 formations on the pull bar 4 rotor 8 is housed.

In order to guarantee result of use, described rotor 8 is prismatic, and there is the round 9 that links together at the middle part; Connector 10 is arranged on the round; Connector 10 rotates and is contained on the bearing pin 3, and stretch out outside the chamber that first button watt 1 and second button watts 2 constitutes at rotor 8 two ends, and rotor 8 and first button watt 1 and second detained between watt chamber inner wall of 2 formations; Its gap is greater than the thickness of the scaffolding steel pipe wall that is fixed, and rotor 8 prismatoidal cross-sectional diameters are less than or equal to the internal orifice dimension of scaffolding steel pipe.

The chute 11 of said wedge pin 7 in it is sleeved on the pull bar 5.

The mode of occupation of the utility model is that the end with two straight tubes of scaffold during use is inserted in respectively on the triangular rotor 8, beats wedge pin 7 then; First button watt 1 and second button watts 2 is fixed together through pull bar 5 firmly, detains when watt being fixed together two, also firmly with two firm being fixed together of straight tube of scaffold; When needs are dismantled; Strike loose wedge pin 7 and get final product, compared with prior art, have following outstanding technique effect:

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, 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.
