Abstract

clamping element for tightening slings made of thin wire ropes or cords to and pipe clamps or to fasten components, characterized characterized in that two cylindrical parts, a fixed one Lower part (1) and a rotatable upper part (2), nest in one another, align with the cylinder axis in the pulling direction of the sling and with a union nut (3) hold together. Furthermore, the loop ends (15) on the lower part (1) through guide holes (12) from opposite introduced at the left a Windungszapfen (6) entangled, through opposite lying insertion holes (7) carried out in the upper part (2) and there, in terminal slots (9) bent outwards, with a clamping element (4) screwed on a clamping collar (8).

Description

The The invention relates to a clamping element for clamping loops from thin Wire ropes or strings, to make hose and pipe clamps or to attach components.

to Production of hose and pipe clamps and for component mounting Become known metal straps or Flat strips, slotted with special turnbuckles or unslotted underneath Use of a special clamping and cutting tool used. For this There are advantages to using it when using thin wire ropes or cords because it allows two bending directions, e.g. Multiple- or crossover wraps manufacture.

task the present invention is to provide a tensioning element, for tightening loops of thin wire ropes or cords to Manufacture hose and pipe clamps or to attach components.

According to the invention this Task solved by that two cylindrical parts, a fixed base and a rotatable upper part, nest with each other, with the cylinder axis Align in the pulling direction of the sling and with a union nut held together.

The Loop ends terminate at the base through guide holes from opposite sides introduced, through insertion holes performed in the top and there, bent in clamping slots to the outside, with a clamping element screwed.

By Turn the upper part, with loosened union nut, through the opposite insertion holes generates a torque on a Windungszapfen, which surrounds the loop ends entangle the winding pin, so as to shorten the noose and hook. The tension is secured by the loosened union nut is attracted.

With The invention is achieved that with a clamping element for clamping thin of slings Wire ropes or strings, Hose and pipe clamps manufactured and components are attached can.

By the entanglement of the loop material around a Windungszapfen, are impermissibly small Bending radii avoided and on the other hand a faster stress build-up reached.

The Loop ends are non-returnable tightened on a clamping collar with a screw.

The fixed base anchored in the loop against reverse rotation in his leadership openings, which also at the same time the possible falling out of the entanglements prevent the loop material from Windungszapfen.

The Tension is through a union nut screw secured by lower and upper part.

The Alignment of the cylinder axis of the lower and upper part in the pulling direction the sling allows fast assembly and compact and simple design.

The Sling can be released at any time the screw connection can be used again.

The when tightening the loop built-up restoring moment, is replaced by a optionally executed, wavy Wreath toothing on the lower and upper part inhibited or held (latches).

With of the invention Double or multiple wraps are made. This is particularly advantageous in hose clamps with high tightness claim and limited clamping length. For sensitive hoses can under the fixed base an additional schooner platen be placed under.

Further Advantages of the invention arise as a result of the extended looping possibilities of Round slings opposite flat strips when attaching e.g. Identification labels in apparatus and pipeline construction. On the tightened and secured top can easily fixings or fixing extensions for e.g. Nameplates are attached.

A Further advantageous application of the invention arises in the component mounting. Analogously known cable loop technique suitable Mehrfachumschlingungen accomplished and fastened with the invented tensioning element. In wraps from corners to components known Seilkantenschoner be used.

At the Attaching the invented tensioning element is not a special tool however, this is necessary when using unslotted ones Metal straps required.

Thin wire ropes and cords are commercially available in a variety of thicknesses, styles, and materials, or can be made to customer specification. A suitable Selection for the use of loops for the purpose of the invention is unproblematic.

The invented tensioning element has a simple structural design and can be cost effective in Series, in different versions, Sizes and Materials are produced.

An embodiment of the invention is based on the 1 to 4 explained. Show it:

1 A side view of the clamping element with loop guide and clamping object.

2 A cross section in section II, shown without loop and clamping object.

3 A view of the clamping element with attachment of eg a base plate for nameplates.

4 A view of the clamping element with an extension for attachment of eg a base plate for name plates.

In the 1 + 2 are the clamping element with cylindrical lower and upper part ( 1 + 2 ), Union nut ( 3 ) and clamping element ( 4 ). Lower and upper part ( 1 + 2 ) are mounted one inside the other and with a union nut ( 3 ) held together.

The lower part ( 1 ) is designed with an external thread ( 11 ), two opposite guide openings ( 12 ) and indentations ( 13 ) for a firm support on mostly round tensioning objects ( 14 ).

The top ( 2 ) has a winding pin ( 6 ), two opposing insertion holes ( 7 ), an inner clamping ring ( 8th ), with two opposing clamping slots ( 9 ) and an internal thread ( 10 ) out.

The clamping element ( 4 ) has an external thread ( 10 ) for the deadlock and an internal thread ( 16 ) for further fixings.

The top ( 2 ), the clamping element ( 4 ) and the union nut ( 3 ) can be designed with a knurling for hand or pliers operation, or with a hexagon for key operation, depending on the intended use of the clamping element.

The inserted loop ends ( 15 ) in lower and upper part ( 1 + 2 ) are in the clamping slots ( 9 ) in the upper part ( 2 ) bent outwards and with the previously removed clamping element ( 4 ) on the clamping collar ( 8th ) tightened. The upper part ( 2 ) Be countered.

After jamming, the upper part ( 2 ) with loosened union nut ( 3 ) to build up the tension in the sling. The loop ends are interlocked ( 15 ) around the winding pin ( 6 ) which shortens the noose. After completion of the distortion rotation, the union nut ( 3 ) tightened to secure the tension.

By an optionally executed, intermeshing crown toothing ( 5 ) at the lower and upper part ( 1 + 2 ), the restoring torque can be restrained during the torsion rotation in small rotation intervals (latches).

3 shows a screw in the female thread ( 16 ) of eg a base plate for a nameplate ( 17 ) on the clamping element.

4 shows a screw in the female thread ( 16 ) from a threaded rod ( 18 ) for an extended attachment of eg a base plate for a nameplate ( 17 ) on the clamping element.
