Abstract
A nylon plug used for wiring protection is composed of a hollow stud and an end portion flange. The hollow stud is provided with an outer screw thread matched with an inner wall screw thread of a metal hose; the end portion flange is provided with a cylindrical member for wrapping the outer wall of the metal hose; and the metal hose is fixed between the cylindrical member and the hollow stud. After the nylon plug of the utility model is connected with the metal hose, the nylon plug has a neat and beautiful appearance without burrs and sharp edges, and an end portion of the metal hose is buckled by the flange, so the end portion of the metal hose dose not loose. The end portion of the metal hose is covered by the cylindrical member of the flange of the plug so as to prevent the end portion of the metal hose from loosing, thereby enabling firm connection of the plug and the metal hose and preventing the plug from tripping, and therefore, a wire can be effectively protected; burrs and sharp edges of the metal hose are covered by the flange of the plug, so the burrs and the sharp edges of the metal hose will not damage the wire; and therefore, with the nylon plug used for wiring protection adopted, problems in wire protection can be effectively solved.
Description
Technical field
The utility model relates to a kind of distribution protection and uses nylon stopper, belongs to trolley coach distribution process for protecting technical field.
Background technology
At present, the line outlet groove electric wire protection of the trolley coach inwall insulated metal flexible pipes that adopt protect more, protect with the tack nylon stopper in hose end, prevent metal hose end burr, sharp edge damage electric wire, because metal hose is formed by thin steel band coiling, easily scattering in work progress in the metal hose end, makes that tack nylon stopper and connection by metal hose are insecure easily to get loose, and causes metal hose end burr, sharp edge might damage electric wire.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the above-mentioned shortcoming of prior art, and a kind of distribution protection nylon stopper is provided.
In order to solve above technical problem, the distribution protection nylon stopper that the utility model provides, composition comprises: hollow double-screw bolt, and end flange, described hollow double-screw bolt is provided with the external screw thread that matches with metal hose spiral inner wall lines, it is characterized in that: described end flange has the cartridge for coated metal flexible pipe outer wall, and metal hose is fixed between described cartridge and the hollow double-screw bolt.
Further, described cartridge has the internal thread that matches with metal hose outer wall spiral lines.
Behind the utility model plug and the connection by metal hose, outward appearance is neat, attractive in appearance; Without burr, sharp edge; Hose end is fastened by flange, does not scatter.The metal hose end is covered by the cartridge of plug flange, and scatter in restriction metal hose end, plug and flexible pipe are connected firmly, and prevents the plug disengagement, thereby effectively protect electric wire; And metal hose end burr, sharp edge are covered by the plug flange, can not damage adjacent exposed electric wire; As seen the protection of the utility model distribution solves the electric wire protection question effectively with nylon stopper.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the sectional structure schematic diagram of embodiment 1 nylon stopper.
Fig. 2 is the sectional structure schematic diagram of embodiment 2 nylon stoppers.
Embodiment
Embodiment 1
The distribution protection nylon stopper of present embodiment, as shown in Figure 1, distribution protection nylon stopper, composition comprises: hollow double-screw bolt 1, and end flange 2, hollow double-screw bolt 1 is provided with the external screw thread 3 that matches with metal hose spiral inner wall lines, end flange 2 has the cartridge 4 for coated metal flexible pipe outer wall, and metal hose is fixed between described cartridge 4 and the hollow double-screw bolt 3.
