Description

A kind of electric wire protection pipe fitting

Technical field

The utility model relates to electric wire, electric cable accessories field, relates in particular to a kind of electric wire protection pipe fitting.

Background technology

The clip of existing threading pipe fitting joint, a most end links to each other with joint component, the other end is that movable axis can be up and down with the junction, fasten the fixedly purpose of penetration pipe to play, the shortcoming of this structure is: when clip is opened repeatedly, easily rupturing in the junction of junction button and joint component, thereby influences the use of whole pipe fitting joint; In addition, existing penetration pipe parts are used for the initiating terminal joint that fixes with body of wall or distribution box one side, and the general volume of nut is bigger, and weight is more heavy, the phenomenon that skew takes place the initiating terminal joint takes place in long-time use the easily, thus influence pass wherein electric wire or the operate as normal of cable; In addition, the waveform of existing penetration pipe, side plan view is a rectangle, and deformability is relatively poor, and angle of bend is restricted easily.

The utility model content

The purpose of this utility model is the deficiency that exists at prior art, solves junction button easily ruptures with the junction of joint component in the use that exists in the prior art phenomenon and the long-time phenomenon that the skew of initiating terminal joint takes place easily of using.

For realizing above-mentioned utility model purpose; the technical scheme that the utility model provides is: a kind of electric wire protection pipe fitting; comprise wire barrel joint, penetration pipe and initiating terminal joint; the two ends of described penetration pipe are individually fixed in an end inboard of described wire barrel joint and initiating terminal joint; it radially is provided with clip with the detachable connection of described wire barrel joint described wire barrel joint upper edge, and described clip is fixed in an end of described penetration pipe by the excircle that grips described penetration pipe the inboard of described wire barrel joint.

Described penetration pipe is the flexible pipe that the outside has wave groove, and it is trapezoidal or semicircle that the cross section of described ripple is.

The outside of described clip is provided with the buckle that is interlockingly connected with the pin-and-hole on the described wire barrel joint, and its inboard is provided with the protruding block tongue that is interlocked with the wave groove outside the described penetration pipe.

Described protruding block tongue is provided with a plurality of along the penetration pipe inboard.

Described protruding block tongue is square block tongue and/or rectangle block tongue.

One end of described wire barrel joint is provided with the rubber neck that is used to reinforce penetration pipe one end.

Described initiating terminal joint comprises nut, part body and spiral shell seat, and the two ends of described body are threaded with nut and spiral shell seat respectively by screw thread, and described nut length accounts for the 1/4-1/3 of the whole length of initiating terminal joint.

The utlity model has following advantage:

A. clip adopts detachable connected mode with the wire barrel joint, making clip is that buckle connects with the connected mode of wire barrel joint, improved the useful life of clip to a certain extent, also be convenient to simultaneously the clip of service failure is in time changed, be unlikely to whole wire barrel joint is changed, promptly saved cost.

B. penetration pipe is rubber or plastics system corrugated flexible hose, and the bellows-shaped of flexible pipe is trapezoidal or semicircle, has strengthened the crooked deformability of penetration pipe, has increased the angle of its distortion, the wearing and tearing that caused owing to self friction when effectively having avoided penetration pipe crooked.

C. reduce hold-down nut in the initiating terminal joint and accounted for the ratio of the whole length of initiating terminal joint, the main weight of initiating terminal joint is concentrated on part body and the spiral shell seat, strengthened the robustness and the stability of initiating terminal joint greatly, effectively avoided existing initiating terminal joint because the overweight problem that easily causes the joint displacement of nut.

Embodiment

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

The utility model mainly comprises: wire barrel joint 1, penetration pipe 2 and initiating terminal joint 3.Wherein, install on the wire barrel joint 1 and be provided with clip 11, clip is provided with square block tongue 111, rectangle block tongue 112 and buckle 113, the outside of one end of wire barrel joint 1 has clip construction opening 13, have pin-and-hole 12 on the wire barrel joint, the clip construction opening 13 that the buckle 113 of clip 11 lower ends passes wire barrel joint 1 outside is with pin-and-hole 12 connection that is fastened.Penetration pipe 2 is for having the rubber or the plastics system flexible pipe of wave groove 21, flexible pipe side waveform is trapezoidal or semicircle, also can be other shape, as shown in Figure 2, thereby strengthened the diastrophic ability of penetration pipe 2, when effectively having avoided penetration pipe 2 crooked because the wearing and tearing that self friction causes; Penetration pipe 2 passes clip 11, and the square block tongue 111 of clip 11 inboards and rectangle block tongue 112 are interlockingly connected with the wave groove 21 in penetration pipe 2 outsides, plays the fixedly effect of penetration pipe 2 positions, avoids moving of penetration pipe 2 front and back positions.Initiating terminal joint 3 is by nut 31, part body 32 and spiral shell seat 33 are formed, nut 31 is provided with the inside spin line, the corresponding setting of external spiral line with part body 32, spiral shell seat 33 is provided with that the inside spin line of external spiral line and part body 32 is corresponding to be provided with connection, wherein, nut 31 accounts for the 1/3-1/2 of whole initiating terminal joint 3 length, the main weight of initiating terminal joint concentrates on part body and the spiral shell seat, this has just strengthened the robustness and the stability of initiating terminal joint greatly, has effectively avoided original joint because the overweight problem that easily causes the joint displacement of nut.

In addition, at an end of wire barrel joint rubber neck 4 can be set, when penetration pipe 2 inserted an end of wire barrel joints 1, rubber neck 4 was placed on the end outside of penetration pipe 2, with the effect of playing sealing and reinforcing.When specifically installing and using, at first rubber neck 4 is placed on an end of penetration pipe 2, then this end is inserted the inboard of wire barrel joint 1, again clip 11 is installed in the clip construction opening 13 on the wire barrel joint 1, the front and back position that suitably adjust penetration pipe 2 this moment just in time places in the wave groove 21 of penetration pipe the square block tongue 111 of clip 11 inboards and rectangle block tongue 112-, play the fixedly effect of bellows, the buckle 113 in clip 11 outsides is sold simultaneously and is gone in the wire barrel joint 1 corresponding pin-and-hole 12, so just penetration pipe 2 is fixed in the wire barrel joint 1 by clip 11.The other end pin of penetration pipe is gone into initiating terminal joint 3 and is fixed, and initiating terminal joint 3 is fixed to wall or distribution box sidewall again, according to the method, just can required the layout of penetration pipe 2 be set according to using.

Wire barrel joint 1 wherein can be two pass joints or three-way connection or four-way connection etc., is not connect the hole count quantitative limitation, is the embodiment of three-way connection among Fig. 1, and a clip 11 that can split mutually with adapter body respectively is set on each joint of three-way connection.

Clip 11 epireliefs play the setting of block tongue, and purpose is that its shape and quantity are not restricted for the better fixedly front and back position of penetration pipe.

The utility model also can have other variation; as well known to the skilled person; the foregoing description only plays the exemplary role in the above-mentioned utility model protection scope; for those of ordinary skills; also have a lot of conventional distortion and other embodiment in the protection range that the utility model limited, these distortion and embodiment will be within the protection ranges that the utility model awaits the reply.
