Abstract
The invention discloses a connecting fastener. The connecting fastener comprises a clamp ring consisting of two semicircular steel profiles, wherein one sides of the clamp ring are connected through a turnover shaft, and the other sides of the clamp ring are provided semicircular arc-shaped bulges in which fixing holes for locking an upright are formed; cleaning holes are formed in the sides of the clamp ring and are in arc shapes, locating blocks which play a role in limiting are arranged inside the cleaning holes, and the surfaces of the locating blocks are provided with rubber cushions for improving the rubbing effect. The upright can be located conveniently, and the installation of a scaffold can be completed quickly; furthermore, the cleaning holes are formed in the side walls of the clamp ring, a person can observe the condition of a connecting piece for fastening a buckled piece, and the rusting or corroding condition can be processed in time, therefore the potential safety hazard can be prevented; in addition, the connecting fastener is excellent in expandable performance and novel in design, thereby being extensive in market promotion prospect.
Description
Technical field
The present invention relates to the support frame of article, particularly relate to a kind of linking fastener.
Background technology
Scaffold refers to that job site is the various supports that operative also solves vertically and horizontal transport is set up.The generic term on building circle, refers to building site be used in the higher place that cannot directly construct of exterior wall, interior decoration or floor height.Mainly for constructor works or the maintenance of perimeter security net and high-altitude installation component etc. up and down, be exactly plainly build a framework, scaffold makes material to be had usually, bamboo and wood, steel pipe or synthetic materials etc.Some engineering is also worked as template with scaffold and is used, and the department such as this external advertising, municipal administration, traffic road and bridge, mine is also extensively used.For a long time, because erecting tools itself and constructing technology thereof and use safety management work are in the state comparatively fallen behind, cause the incidence of accident higher.Related statistical surface: in annual the occurred casualty accident of Chinese architecture construction system, nearly about 1/3 is relevant with the problem of erecting tools and use thereof directly or indirectly.Support frame is in the process of installing, and fastener plays vital reusing, and is related to the property safety of people.
In sum, for the defect of prior art, the special one that needs is connected fastener, to solve the deficiencies in the prior art.
Summary of the invention
For the deficiency that scaffold in prior art exists in installation process, bring very large drawback to actual employing, the present invention proposes a kind of linking fastener, novel in design, by column is nested in above fastener completely, guarantee scaffold safety in use, to address the deficiencies of the prior art.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of linking fastener, comprise snap ring, snap ring is made up of two semicircular steel profile, between snap ring, side is connected by trip shaft, and the opposite side of snap ring is provided with semicircular arc projection, offers the fixing hole of locking column above projection, cleaning eye is offered above the side of snap ring, the shape of cleaning eye is circular arc, and the locating piece playing limit function of the inner side installation of cleaning eye, the surface of locating piece is provided with the rubber pad increasing rubbing action.
Distance between adjacent two projections of the present invention is 2mm-5mm, and the diameter of snap ring is 40mm.
Further, the flip angle of described snap ring is 0 degree to 180 degree.
The invention has the beneficial effects as follows: this product structure is simple, conveniently column can be positioned, complete the installation of scaffold fast, by the sidewall at snap ring, cleaning eye is set, people can be observed in time by the situation of the fastening connector of fastener, when finding to occur the situation of getting rusty or corroding, can process timely, avoiding producing potential safety hazard.Scalable Performance is excellent, novel in design, is a kind of well innovation scheme, has very much marketing prospect.
Accompanying drawing explanation
The present invention is described in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is structural representation of the present invention.
detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
See Fig. 1, a kind of linking fastener, comprise snap ring 1, snap ring 1 is made up of two semicircular steel profile, between snap ring 1, side is connected by trip shaft 14, and the opposite side of snap ring 1 is provided with semicircular arc projection 2, and protruding 2 offer the fixing hole 3 of locking column above, cleaning eye 4 is offered above the side of snap ring 1, the shape of cleaning eye 4 is circular arc, and the locating piece playing limit function of the inner side installation of cleaning eye 4, the surface of locating piece is provided with the rubber pad increasing rubbing action.Distance between adjacent two projections 2 is 2mm-5mm, and the diameter of snap ring 1 is 40mm.The flip angle of snap ring 1 is 0 degree to 180 degree.
The present invention is effective is: structure is simple, conveniently column can be positioned, complete the installation of scaffold fast, by the sidewall at snap ring, cleaning eye is set, people can be observed in time by the situation of the fastening connector of fastener, when finding to occur the situation of getting rusty or corroding, can process timely, avoiding producing potential safety hazard.Scalable Performance is excellent, novel in design, is a kind of well innovation scheme, has very much marketing prospect.
The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
