Description
Technical field
The utility model relates to a kind of link, and more particularly, it relates to a kind of link connected for automobile hard tube.
Background technique
Some special pipelines need the sidewall through certain device in the car, connect the two tubes inside and outside sidewall two ends or device, usually need special link to connect in these occasions.Particularly mostly be hard tube at the pipeline that this occasion is used, and link and pipeline enclosure must be threaded connection, and its one end must be had when connection two pipelines and fix, cause like this pipeline transfer occurring when connecting or causing storing elastic force in the duct.Therefore it can avoid two pipelines to rotate when connecting to need to design a kind of link.
Model utility content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of link connected for automobile hard tube, its role is to the problem that solution pipeline rotates when connecting.
For achieving the above object, the utility model provides following technological scheme: a kind of link connected for automobile hard tube, comprise link body, described link body is cylindrical, an end face of described link body is provided with tapped hole, described link body the other end end face is provided be communicated with tapped hole and with the cylindrical hole of tapped hole coaxial line, described tapped hole diameter is greater than cylindrical hole diameter, described cylindrical hole inwall is provided with planar projections, described link body outer side wall is provided with the otch running through an end face, two tangent planes of described otch respectively with the axis parallel of link body and vertical.
The utility model is set to further: described cylindrical hole and tapped hole are inclined to set, and the shaft axis of described cylindrical hole and tapped hole and the shaft axis of link body are at grade and crossing.
The utility model is set to further: described tapped hole place end face is vertical with tapped hole shaft axis to be arranged.
The utility model is set to further: the end face dual-side of described planar projections is crossing with through-hole wall, and the cross section of described through hole is D shape.
The utility model is set to further: be provided with the Seal cage for placing seal ring with tapped hole coaxial line between described through hole and tapped hole.
The utility model is set to further: described Seal cage is frustoconic shape, and one end that described Seal cage area is little is connected with through hole, and described Seal cage small end face diameter is identical with through-hole diameter.
In use, in Seal cage, place seal ring, then by pipeline little for diameter through through hole, the one end passed fixed, then link body is installed to need through device sidewall on, threaded threaded tube finally will be set and be connected with tapped hole.
By adopting technique scheme, the utility model has following effect:
First aspect, by arranging the protruding problem changing tube circular and can rotate of a platform on through hole madial wall, avoid establishing threaded threaded tube and link body to drive when being connected the little pipeline of diameter to rotate and affect the connection of this pipeline the other end, or avoiding this pipeline retaining elastic force causes the connection generation of the other end to loosen, and in use produces potential safety hazard; Simultaneously because the little pipeline of diameter and link body circumference secure, therefore in order to avoid link body and threaded tube be because link drives the pipeline that diameter is little to rotate being connected, therefore a breach is set on the outer side wall of link body, when making on its sidewall being arranged on device, circumference is fixing, and link body can be avoided to drive the little pipeline of diameter to rotate the connection that also can facilitate between link body and threaded tube.
Second aspect, cylindrical hole and tapped hole are inclined to set, the utility model can be made to be applicable to crooked pipeline, to avoid using crooked pipeline to be connected with link body and problem that another port position of fixing tool rest crooked pipeline due to the circumference of link body cannot adjust; And end face arrange vertical with tapped hole shaft axis in tapped hole place can increase connectivity robustness between threaded pipe and link body and sealing.

Embodiment
Referring to figs. 1 through Fig. 3, the link that the utility model is used for the connection of automobile hard tube is described further.
Be a kind of mode of execution of a kind of link for the connection of automobile hard tube of the utility model as shown in Figure 1 to Figure 3, it comprises link body 1, link body 1 is cylindrical, an end face of link body 1 is provided with tapped hole 2, link body 1 the other end end face is provided be communicated with tapped hole 2 and with the cylindrical hole 4 of tapped hole 2 coaxial line, tapped hole 2 diameter is greater than cylindrical hole 4 diameter, cylindrical hole 4 inwall is provided with planar projections 5, the end face dual-side of this planar projections 5 is crossing with through hole 4 inwall, the cross section of this through hole 4 is made to be D shape.
In addition, the outer side wall of link body 1 is provided with the otch 6 running through an end face and sidewall, two tangent planes of this otch 6 respectively with the axis parallel of link body 1 and vertical.And between through hole 4 and tapped hole 2, be provided with the Seal cage 3 for placing seal ring with tapped hole 2 coaxial line, Seal cage 3 is in frustoconic shape, one end that Seal cage 3 area is little is connected with through hole 4, and Seal cage 3 small end face diameter is identical with through hole 4 diameter, this setting is for increasing the connection sealing of threaded tube and the little pipeline enclosure of diameter.
In addition, cylindrical hole 4 and tapped hole 2 are inclined to set, and at grade and crossing, and tapped hole 2 place end face is vertical with tapped hole 2 shaft axis arranges for the shaft axis of cylindrical hole 4 and tapped hole 2 and the shaft axis of link body 1.
In use, in Seal cage 3, place seal ring, then by pipeline little for diameter through through hole 4, the one end passed is fixed, then link body 1 is installed to need through device sidewall on, threaded threaded tube finally will be set and be connected with tapped hole 2.
By adopting technique scheme, the utility model has following effect:
First aspect, by arranging the protruding problem changing tube circular and can rotate of a platform on through hole 4 madial wall, avoid establishing threaded threaded tube and link body 1 to drive when being connected the little pipeline of diameter to rotate and affect the connection of this pipeline the other end, or avoiding this pipeline retaining elastic force causes the connection generation of the other end to loosen, and in use produces potential safety hazard; Simultaneously because the little pipeline of diameter and link body 1 circumference secure, therefore in order to avoid link body 1 and threaded tube be because link drives the pipeline that diameter is little to rotate being connected, therefore a breach is set on the outer side wall of link body 1, when making on its sidewall being arranged on device, circumference is fixing, and the pipeline that link body 1 can be avoided to drive diameter little rotates the connection that also can facilitate between link body 1 and threaded tube.
Second aspect, cylindrical hole 4 and tapped hole 2 are inclined to set, the utility model can be made to be applicable to crooked pipeline, to avoid using crooked pipeline to be connected with link body 1 and problem that another port position of fixing tool rest crooked pipeline due to the circumference of link body 1 cannot adjust; And arrange vertical with tapped hole 2 shaft axis of end face of tapped hole 2 place can increase connectivity robustness between threaded pipe and link body 1 and sealing.
The above is preferred implementation of the present utility model, and under not departing from the prerequisite of the utility model principle for the person of ordinary skill of the art, can also make some modification and improvement, these also should be considered as protection domain of the present utility model.
