Abstract
The utility model relates to a spiral conversion connecting piece, which is characterized in that the connecting piece is a pipy connecting piece; spiricles are formed at the two ends of the connecting piece; the calibers of the spiricles which are standard specification can be either English system standard specification size or metric standard specification size; and the connecting spiricles of the two ends of the connecting piece can be either internal spiricles or external spiricles. The connecting piece has the advantages that the allocation of a connecting piece can be chosen according to actual requirements, thereby flexibly coping with the connection requirements for various spare part interfaces.
Description
[technical field]
The utility model relates to mechanical component and makes the field, relates in particular to a kind of spiral conversion link.
[background technique]
In mechanical manufacturing field, for length scales, there are metric system and two kinds of standards made in Great Britain in the world, the mechanical component of China is taked the metric system standard usually, and the mechanical tool of import because the source is different, might be standard with the English system.If taked inch screw thread such as the installation of the part on the import equipment, when needs are equipped with homemade spare part, may can't directly install because the standard of screw thread is different, cause maintenance debugging or operational outfit not to carry out smoothly, incur loss through delay the duration thus, reduce working efficiency or the like.
So just press for a kind of link, can change metric system and spare part standard interface made in Great Britain.
[model utility content]
The technical problems to be solved in the utility model provides a kind of spiral conversion link, to solve the problem that connection can not directly be installed of different systems machinery zero spare part.
A kind of spiral conversion link described in the utility model is characterized in that described link is a tubular connection, and two ends is provided with spiral lamination, and the bore of described spiral lamination is a standard size.Can be the inch standard specification, also can be the metric system standard measure.The connection spiral lamination at link two ends can be the internal spiral line, also can be the external spiral line, and the middle part is provided with outer six and is convenient to disassembling section.
The spiral conversion link of tubulose described in the utility model, two ends are provided with the metric system or the imperial sizing spiral lamination of standard size, and the multiple connection configuration of internal and external screw line, can tackle the connection needs of dissimilar zero spare part interfaces flexibly.
[description of drawings]
Fig. 1 is a kind of spiral conversion link structural representation described in the utility model;
Fig. 2 is an another kind of spiral conversion link structural representation described in the utility model.
[embodiment]
Below in conjunction with Figure of description a specific embodiment of the present utility model is elaborated.
A kind of spiral conversion link as shown in Figure 1, the connecting thread at these link two ends is the external spiral line, and one end (termination 1) is a NPT standard size screw thread made in Great Britain, and the other end (termination 2) is a metric system standard size screw thread.The middle part is processed into outer hexagonal shaped formula and is beneficial to disassembling section.
Another kind of spiral conversion link and for example shown in Figure 2, the connecting thread at these link two ends, an end (termination 3) are arranged to internal spiral NPT standard size made in Great Britain, and the other end (termination 4) is an external spiral metric system standard size.
Similar above two kinds of links, the utility model also can also derive internal and external screw line conversion link on the Placement, can derive the unidimensional forms such as metric system, the conversion of different size metric system, different size conversion made in Great Britain of changeing made in Great Britain on specification.
Corresponding standard of the specification of metric and English size such as following table:
| Standard | Specification | Specification | Specification | Specification |
| Made in Great Britain | 1/8” | 1/4” | 3/8” | 1/2” |
| Metric system | M10 | M14 | M16 | M20 |
When making required spiral conversion link, only need link two ends spiral lamination be made corresponding English system/metric system structure according to above specification standards, get final product.
The Material Processing of spiral conversion link can,, be handled applicable to different medium and operating mode for processing raw material with materials such as copper, carbon steel, stainless steel, PVC according to actual needs flexibly.
Above embodiment is the unrestricted the technical solution of the utility model in order to explanation only.Any modification or partial replacement that does not break away from the utility model spirit and scope all should be encompassed in the middle of the claim scope of the present utility model.
Claims (6)
1, a kind of spiral conversion link is characterized in that described link is a tubular connection, and two ends is provided with spiral lamination, and the bore of described spiral lamination is a standard size.
2, spiral as claimed in claim 1 is changed link, it is characterized in that the spiral lamination of described link termination, is the inch standard specification.
3, spiral as claimed in claim 1 or 2 is changed link, it is characterized in that the spiral lamination of described link termination, can also be metric system standard size size.
4, spiral as claimed in claim 1 is changed link, it is characterized in that the spiral lamination of described link termination, is the external spiral line.
5, as claim 1 or 3 described spiral conversion links, it is characterized in that the spiral lamination of described link termination, can also be the internal spiral line.
6, spiral conversion link as claimed in claim 1 is characterized in that the middle part of described tubular connection is provided with outer six sides.
