Description
Technical field
The utility model is related to a kind of screw rods, more particularly to a kind of general conversion screw rod.
Background technology
Traditional RM6 ring main unit ends use American pyrocondensation cable elbow-shaped connector, active time more than equal 20 years,
Its insulation performance declines already, can not adapt to more and more load, need to change.And now the American cable elbow of this model
Type joint stops production already, can only use European cable elbow-shaped joint replacing, but original-pack cabinet screw hole hole position and European cable elbow-shaped
Nipple orifice position is not inconsistent.European elbow-type connector is one of the Novel electric cable end used now, and good insulation preformance, safety coefficient is high,
In order to which traditional RM6 ring main units end is replaced with European elbow-type connector, screw rod has to be customized, the first inserting section symbol
It closes RM6 cabinets hole position and screw thread, the second inserting section meets European elbow-type nipple orifice position and screw thread.
Utility model content
Using American screw rod, novel European elbow-type connector needs to use European spiral shell the screw of traditional pyrocondensation block head
Bar, in order in the case where ensureing that former nut thread is constant, and can perfection agree with novel European elbow-type connector, the utility model
A kind of general conversion screw rod is provided, which is to retain former American screw thread by the American and European new screw being combined,
Using European screw thread.
The technical solution of the utility model is；A kind of general conversion screw rod, the both ends of the screw rod are respectively equipped with the first grafting
Section and the second inserting section, first inserting section be equipped with American screw thread, second inserting section be equipped with European screw thread, described first
Inserting section is for being inserted into RM6 cabinets hole position, and second inserting section is for being inserted into European elbow-type nipple orifice position, first grafting
Changeover portion is equipped between section and the second inserting section, the changeover portion is truncated conical shape, European for the second inserting section to be clamped on
In elbow-type connector.
Preferably, the top of the first inserting section be equipped with notch, convenient for the first inserting section preferably with the hole of RM6 cabinets position contract
It closes, is easier when being rotated.
Preferably, the American reach of the first inserting section is 52mm, and the European reach of the second inserting section is 24mm,
The length of changeover portion is 10mm.According to the length for using the standard setting screw rod, it is made preferably to be attached.
Preferably, which is made using alloy steel products material, and corrosion resistance is strong, and service life is long.
The utility model has the beneficial effects that；Using this tool, then European elbow-type connector can be applied to RM6 looped networks
Cabinet replaces original pyrocondensation block head, improves performance, prolongs the service life；In the case where ensureing that former nut thread is constant, and energy
Enough perfections agree with novel European elbow-type connector.

Illustrate, should not be understood as the limitation to this patent.
Embodiment 1：
As depicted in figs. 1 and 2, the both ends of a kind of general conversion screw rod, the screw rod are respectively equipped with the first inserting section 1 and second
Inserting section 2, the first inserting section 1 are equipped with American screw thread 11, and the second inserting section 2 is equipped with European screw thread 21, and the first inserting section 1 is for inserting
Enter 4 hole of RM6 cabinets position, the second inserting section 2 is for being inserted into European 5 hole of elbow-type connector position, the first inserting section 1 and the second inserting section 2
Between be equipped with changeover portion 3, changeover portion 3 be truncated conical shape, for the second inserting section 2 to be clamped in European elbow-type connector 5.
In the present embodiment, the top of the first inserting section 1 be equipped with notch 12, convenient for the first inserting section 1 preferably with RM6 cabinets
The hole position of body 4 is agreed with, and is easier when being rotated.
In the present embodiment, 11 length of American screw thread of the first inserting section 1 is 52mm, the European screw thread of the second inserting section 2
21 length are 24mm, and the length of changeover portion 3 is 10mm.According to the length for using the standard setting screw rod, it is made preferably to carry out
Connection.The conversion screw rod is made using alloy steel products material, and corrosion resistance is strong, and service life is long.
Obviously, above-described embodiment of the utility model is only intended to clearly illustrate the utility model example, and
It is not the restriction to the embodiment of the utility model.For those of ordinary skill in the art, in above description
On the basis of can also make other variations or changes in different ways.There is no need and unable to give all embodiments
It is exhaustive.All any modification, equivalent and improvement made within the spirit and principle of the present invention etc., should be included in
Within the protection domain of the utility model claims.
