Abstract
The utility model is a snake shin tube which is characterized in firm combination and good effect of water resistance, consisting of multiple segment tubes. Two adjacent segment tubes are connected through pressing and fastening the inner concave groove of the front segment tube with the inner convex groove of the back segment tube, and through pressing and fastening the inner convex groove of the segment tube with the inner concave groove of the back segment tube. The pressed and fastened parts of two adjacent segment tubes are more than two parts. The convex and concave grooves of the exterior are helical. The utility model is especially suitable for being applied as the protective sleeve for the electrical wire or the cable.
Description
Technical field: the utility model relates to technical field of electric wires and cables, and exactly it is a kind of electric wire protection flexible metal conduit.
Background technology: flexible metal conduit is a protection pipe box commonly used in a kind of electric power system; it is commonly used in and need arbitrarily changes direction; and don't the occasion that need fix, as: the protection pipe box of all kinds of lathe lighting lamp tool leads, the protective sleeve of underground electric wire etc.; but; existing flexible metal conduit exists following some shortcomings, at first is insecure, easily disconnects; next is that waterproof effect is poor; easily leak, cause short circuit easily, the intensity difference of being exactly is arranged again; crush easily; thereby when being used as electric wire protection pipe box, need on this flexible metal conduit, to wrap plastic film, like this; promptly take a lot of work and require great effort, and it is conscientiously careful to require the constructor to work.
Summary of the invention: the utility model is for a kind of flexible metal conduit is provided, and not only intensity is good for it, and in conjunction with firmly, and waterproof effect is better, but free bend also.It is achieved by the following scheme, it is made up of the more piece pipe, it is characterized in that: the connection of adjacent 2-section pipe is that forward pipe joint pipe inner groovy (1) presses together with the interior tongue (2) of back pipe joint pipe, tongue (3) presses together with back pipe joint pipe inner groovy (4) and couples together in the preceding pipe joint pipe, and pressing place of adjacent 2-section pipe is more than two places.The groove of the convex-concave of outer surface is a helical form.Because the utility model is more piece pressing between the adjacent 2-section pipe, thereby in conjunction with firmly, intensity and withstand voltage effect and waterproof effect are all better, but and free bend, be fit to produce continuously, the production efficiency height is particularly suitable for using as the protective sleeve of electric wire.Also can be applicable to others.
Description of drawings: Fig. 1 is a structural representation of the present utility model.
Embodiment: the utility model can adopt sheet metal to manufacture, better with zinc coated sheet, the galvanized sheet that is cut into bar is placed on the coiling machine to twine gets final product, design outer surface flute shape as required, manufacture the compacting roller, prosthomere and deutomerite are that a galvanized sheet roll extrusion forms.Before groove 1 in the pipe joint press together with tongue 2 in the pipe joint of back, the tongue 3 in the preceding pipe joint presses together with back pipe joint inner groovy 4, more piece is connected in one.During use, electric wire or cable are placed in the flexible metal conduit internal diameter, with the helical form outer surface flexible metal conduit are connected, effectively interior electric wire of protection tube or cable are subjected to the erosion of sandstone, sewage, the useful life of extending wire cable.
Claims (2)
1, flexible metal conduit, it is made up of the more piece pipe, it is characterized in that: the connection of adjacent 2-section pipe is that forward pipe joint pipe inner groovy (1) presses together with the interior tongue (2) of back pipe joint pipe, tongue (3) presses together with back pipe joint pipe inner groovy (4) and couples together in the preceding pipe joint pipe, and pressing place of adjacent 2-section pipe is more than two places.
2, a kind of flexible metal conduit according to claim 1 is characterized in that: the groove of the convex-concave of outer surface is a helical form.
