Abstract

The utility model relates to a coiled pipe with an improved structure, which is formed by connecting a connecting pipe, a nozzle pipe and a plurality of middle pipes in series, wherein one end of the connecting pipe is provided with a thread head and the other end is provided with a ball body. One end of each middle pipe is provided with a ball body, and the other end is provided with a ball socket. One end of the nozzle pipe is provided with a ball socket, the ball sockets on the connecting pipe, the middle pipes and the nozzle pipe are orderly sheathed on the ball body of the other pipe body, and then the connecting pipe, the middle pipes and the nozzle pipe can be connected in series to form a coiled pipe which can be arbitrarily bent. The bottom ends of the ball sockets are provided with external threads, and a ring which can tighten the lower ends of the ball sockets is spirally arranged on each ball socket respectively to avoid the phenomenon of oil leakage caused by the breakage of the ball sockets.

Description

A kind of coiled pipe that improves structure

The utility model relates to a kind of coiled pipe that improves structure, refer in particular to a kind of outside the ball-and-socket at each serial connection place of coiled pipe spiral shell be provided with a ring, produce the coiled pipe of leakage of oil situation to avoid ball-and-socket to break.

General lathe must add cutting agent (cooling or lubricant oil), and cutting agent is through the coiled pipe spray in good time when cutting metal material.Common coiled pipe is to be composed in series by connecting tube, nozzle pipe and a plurality of intervalve, and wherein an end of connecting tube has thread head, and the other end has spheroid; One end of intervalve has spheroid, and the other end has ball-and-socket; One end of nozzle pipe has ball-and-socket, in regular turn the ball-and-socket on connecting tube, intervalve and the nozzle pipe is enclosed within on the spheroid of another body, promptly is concatenated into a coiled pipe of deflection arbitrarily; Tight for the ball-and-socket and the spheroid socket that make above-mentioned each body, common coiled pipe is made with having micro-flexible plastic cement material, leaks to prevent cutting agent.Yet this coiled pipe made from plastic cement material because the pushing of reaction force that circumferential section under the ball-and-socket is produced when being subjected to the spheroid assembling is easy to generate slight crack, causes the cutting agent leakage when crooked arbitrarily, and severe patient even fracture influence proper functioning.

The purpose of this utility model is the structure of coiled pipe commonly used is improved, so that a kind of oiling coiled pipe that prevents that cutting agent from spilling to be provided.

The purpose of this utility model realizes by following technological means: a kind of coiled pipe that improves structure, compose in series by connecting tube, nozzle pipe and a plurality of intervalve, and wherein: an end of connecting tube has thread head, and the other end has spheroid; One end of intervalve has spheroid, and the other end has ball-and-socket; One end of nozzle pipe has ball-and-socket, it is characterized in that: the ball-and-socket bottom of intervalve and nozzle pipe is provided with outside thread, and spiral shell is provided with the ring that can tighten the ball-and-socket lower end on it.

Advantage of the present utility model is: because the outer spiral shell of ball-and-socket is provided with the ring that can strengthen ball-and-socket next week along intensity, ball-and-socket is closely tightened on spheroid, thereby reach the purpose that prevents that cutting agent from leaking.

Below in conjunction with accompanying drawing structure of the present utility model is described in detail.

Fig. 1 is a sectional view of the present utility model.

Fig. 2 is a three-dimensional exploded view of the present utility model.

Fig. 3 is a sectional exploded view of the present utility model.

Fig. 4 makes embodiment for of the present utility model another.

Among the figure: 1 connecting tube, 11 thread heads, 12 spheroids, 2 nozzle pipes, 21 ball-and-sockets, 211 outside threads, 3 intervalves, 31 spheroids, 32 ball-and-sockets, 321 outside threads, 4 rings, 41 internal threads, 5 desk lamps, 51 lampshades, 10 coiled pipes.

As Fig. 1, Fig. 2 and shown in Figure 3, the utility model is composed in series by connecting tube 1, nozzle pipe 2 and a plurality of intervalve 3, and wherein: an end of connecting tube 1 has thread head 11, and the other end has spheroid 12; One end of intervalve 3 has spheroid 31, and the other end has ball-and-socket 32; One end of nozzle pipe 2 has ball-and-socket 21; Ball-and-

socket

32 and 21 on connecting tube 1, intervalve 3 and the nozzle pipe 2 is enclosed within on the

spheroid

31 and 21 of another body, promptly is concatenated into a coiled pipe 10 of deflection arbitrarily.Ball-and-

socket

32 and 21 bottoms are provided with

outside thread

321 and 211, spiral shell is provided with a ring 4 with internal thread 41 on it, ring 4 is used for tightening the lower end of ball-and-

socket

32 and 21, the reaction force that makes it can have higher intensity to bear suit spheroid 31 and produced at 21 o'clock, preventing its along being subjected to this reaction force and producing the situation of breaking, thereby can avoid taking place the situation of leakage of oil next week.

As shown in Figure 4, coiled pipe 10 also can be installed on the lampshade 51 of desk lamp 5, as another embodiment of the present utility model.

Claims

1, a kind of coiled pipe that improves structure is composed in series by connecting tube, nozzle pipe and a plurality of intervalve, and wherein: an end of connecting tube has thread head, and the other end has spheroid; One end of intervalve has spheroid, and the other end has ball-and-socket; One end of nozzle pipe has ball-and-socket, it is characterized in that: the ball-and-socket bottom of intervalve and nozzle pipe is provided with outside thread, and spiral shell is provided with the ring that can tighten the ball-and-socket lower end on it.
