Abstract
The utility model provides a stainless reduction pipe with screw threads, which comprises a steel pipe body and a reduction part. The outer diameter of the reduction part is smaller than the diameter of the steel pipe body and is larger than the inner diameter of the larger than body, steel pipe bodies of other steel pipes can be sheathed at the reduction part, therefore the steel pipes with reduction ports can be connected with each other so as to have the advantage of convenient use, and in addition, the reduction part can be provided with a section of screw threads which are used for making the stainless reduction pipe with screw thread and other steel pipes connected with each other keep fixed in an axial direction.
Description
Technical field
The utility model relates to a kind of stainless steel threaded steel pipe, particularly a kind of stainless steel screw thread draw.
Background technology
Stainless steel threaded steel pipe or stainless steel enclosure wall tube in the application of industries such as furniture more and more widely, it is easily manufactured with frame as furniture that this mainly has benefited from the stainless steel threaded steel pipe, and profile is good-looking, it is also little to take volume.Yet, but run into difficulty at the stainless steel threaded steel pipe that connects different size.When using the stainless steel threaded steel pipe, only use the steel pipe of single size at present, and will carry out by desired size, or use corresponding joint connector, connect steel pipe at workshop as the furniture frame.Like this, just give and use this stainless steel threaded steel pipe to make troubles as support.
Summary of the invention
A problem to be solved in the utility model provides a kind of stainless steel threaded steel pipe that contains draw mouth.
In order to realize above-mentioned purpose of the present utility model, the stainless steel screw thread draw that the utility model provides comprises: steel tube body and reducing part, the overall diameter of reducing part is less than the diameter of steel tube body and greater than the internal diameter of steel tube body.
Further, the stainless steel tube reducing that provides at the utility model partly contains one section screw thread, and this screw thread is used to make the coupled steel pipe of the stainless steel screw thread draw axially being maintained fixed.
The stainless steel screw thread draw that the utility model provides contains the reducing part, the outside dimension of this reducing part is less than the diameter of steel tube body, internal diameter greater than steel tube body, make another steel tube body can be enclosed within on this reducing part, thereby this steel pipe that has reducing can be connected with each other, and, because the reducing part can contain one section screw thread, this screw thread is used to make the coupled steel pipe of stainless steel axially being maintained fixed, and uses convenient.
Description of drawings
Fig. 1 is the section of the embodiment stainless steel screw thread draw providing of the utility model.
Fig. 2 is the schematic diagram of another steel pipe of being connected of the reducing of the stainless steel screw thread draw that provides with the utility model.
The specific embodiment
Referring to Fig. 1, stainless steel tube is to adopt the stainless steel enclosure wall tube.The stainless steel enclosure wall tube is made up of internal layer-carbon steel layer and skin-stainless steel layer.Skin-stainless steel layer is wrapped in the outside of carbon steel layer, thereby plays rust inhibition, and glossy.This steel pipe is because very hard, and skin is very crisp again, and existing technology can not be processed into reducing.Stainless steel reducing pipe is made up of two parts, and right-hand component is a steel tube body 1, and the left side is a reducing part 2.The outside dimension of reducing part is less than the outside dimension of steel tube body 1, but greater than the internal diameter size of steel tube body 1.The length of reducing part 2 can be used and the external diameter of pipe is decided according to actual.Outside in the left part of reducing part 2 is provided with one section screw thread 3.
Fig. 2 is the schematic diagram of another stainless steel threaded steel pipe of being connected of the reducing of the stainless steel screw thread draw that provides with the utility model.As shown in the figure, be provided with an excrescence 4 that protrudes on corresponding that surface of threaded portion that the reducing of the stainless steel screw thread draw this stainless steel threaded steel pipe and shown in Figure 1 is connected.This excrescence 4 can embed in the groove of above-mentioned reducing screw thread partly.Like this, when the stainless steel screw thread draw was connected with this steel pipe, when the stainless steel screw thread draw and this steel pipe rotated mutually, above-mentioned excrescence 4 can move in the groove of the screw thread of reducing part, so the reducing part can enter in the above-mentioned steel pipe.At last, excrescence 4 is embedded in the groove of screw thread, so, reducing part can not be in steel pipe move left and right, like this, the stainless steel screw thread draw is stablized with another stainless steel threaded steel pipe be connected, reach and connect effect preferably.
Equally, the inner surface of the appropriate section of another stainless steel threaded steel pipe that the reducing of the stainless steel screw thread draw that provides with the utility model is connected can use screw socket, this screw socket is connected with the screw thread 3 of the left part of above-mentioned reducing part 2, the stainless steel screw thread draw and another stainless steel threaded steel pipe is stablized be connected.
Claims (4)
1, a kind of stainless steel screw thread draw is characterized in that it comprises: steel tube body and reducing part, the overall diameter of reducing part is less than the diameter of steel tube body and greater than the internal diameter of steel tube body.
2, the stainless steel screw thread draw as claimed in claim 1 is characterized in that, partly contains one section screw thread in reducing, and the steel pipe that this screw thread is used to the stainless steel draw and other are connected axially is being maintained fixed.
3, the stainless steel screw thread draw as claimed in claim 2 is characterized in that, the corresponding inner surface that is connected of its steel pipe that is connected is provided with an excrescence with stainless steel tube, and this excrescence can embed in the groove of reducing screw thread partly.
4, the stainless steel screw thread draw as claimed in claim 2 is characterized in that, the corresponding inner surface of the steel pipe that it is connected with stainless steel tube is provided with screw socket, and this screw socket can be connected with the screw thread of reducing part.
