Abstract

A clamping arrangement for clamping a tubular member to another member comprises two interengaging parts 10 at least one of which has an integral deformable portion 13 which, when the two parts are screwed together via internal threads 17 and external threads 12 on the two parts is deformed by a portion on the other part whereby to clamp the two parts to the tubular member without the need for a separate olive. The arrangement may be used to clamp a rod or tube to a plate, or to form a fluid-tight coupling for tubes with low hydraulic pressure. <IMAGE>

Description

SPECIFICATION Clamping arrangement The present invention relates to a clamping arrangement for example for clamping a rod or tube to a further member e.g. a plate and more particularly to a member used in the clamping arrangement.
It is known that a rod or a tube can be connected to a further member by compressing an olive against the exterior of the rod or tube using two relatively rotatable members which interengage, to axially compress the olive. This type of arrangement requires two members of cooperating shapes as well as a separate olive which means that for each connection three differently shaped members have to be produced which is expensive.
The present invention provides a clamping arrangement comprising a first tubular member having a bore arranged to receive an object to be clamped, which member comprises an externally threaded portion and an integral nose portion extending therefrom, the arrangement further comprising a second member being provided with an internally threaded portion for engagement with the externally threaded portion of the first member, and a tapering bore portion for engagement with the nose portion of the first member to cause the nose portion to deform onto the object and hence clamp the two members onto the object.
In the preferred embodiment the two members are identical and each comprises a first portion having the features of the first mentioned member, and a second portion having the features of the second mentioned member.
Features and advantages of the present invention will become apparent from the following description of an embodiment thereof when taken in conjunction with the accompanying drawing which shows a crosssectional deviation of one of a pair of members which constitute a clamping arrangement according to the present invention.
The clamping arrangement comprises two members 10 each as shown in the drawing. The member 10 comprises a head portion 1 an externally threaded body portion 12 and an integral tapering nose portion 13 which serves the same purpose as the "olive" in use. A bore 15 extends through the length of the member 10 and is internally threaded and of a diameter in the head portion 1 1 to mate with the body portion 12 of a further member in use. A tapering bore portion 16 connects the internally threaded portion of the bore with a smooth section 17 of lesser diameter than the internally threaded portion of the bore.The diameter of the section 17 is chosen to be a sliding fit on the rod or tube to be connected and the tapering portion 16 is arranged to mate with the nose portion 13 so as to cause the nose portion 13 to be deformed onto the rod or tube so as to clamp the two members to the rod or tube.
If one of the members 10 is screwed into a plate, the rod or tube will thus be connected to the plate.
The above arrangement prevents any axial or rotary movement. The application of the arrangement will determine the material and machinery detail to achieve an adequate seal under pressure. For example, when the arrangement is made of steel, does not give a high hydraulic pressure tight joint, i.e. pressures much above mains water pressure. Use of a more ductile material will enable the clamping arrangement to withstand even higher pressure.
Plastics materials may be used.
Claims
1. A clamping arrangement comprising a first tubuluar member having a bore arranged to receive an object to be clamped, which member comprises an externally threaded portion and an integral nose portion extending therefrom, the arrangement further comprising a second member being provided with an internally threaded portion for engagement with the externally threaded portion of the first member, and a tapering bore portion for engagement with the nose portion of the first member to cause the nose portion to deform onto the object and hence clamp the two members onto the object.
2. A clamping arrangement asscíaimed in claim 1 wherein the first and second members are identical and each comprise a first portion including an externally threaded portion and a nose portion, and a second portion including an internally threaded portion and a tapering bore portion.
3. A clamping arrangement as claimed in claim 2, wherein the tapering bore portion joins the internally threaded portion to the externally threaded portion.
4. A clamping arrangement as claimed in any preceding claim wherein the first and second members are made of metal.
5. A clamping arrangement as claimed in any one of claims 1 to 3 wherein said first and second members are made of plastic.
6. A clamping arrangement as hereinbefore described with reference to the accompanying drawing.
