Abstract
The utility model discloses a kind of threeway link bolts, including bolt body, the top of bolt body has extended segment, the outer wall of extended segment is equipped with external screw thread, the inside of extended segment has conical surface interface, conical surface interface is used for connecting with pipe fitting, and pipe fitting is taper joint, and the oil duct inside bolt body penetrates through conical surface interface.The threeway link bolt has threeway linkage function, and latus rectum is big, and flow resistance is small.
Description
Technical field
The utility model is related to link bolt, more particularly to a kind of threeway link bolt.
Background technology
The connection type of total member (injection pump, bavin filter etc.) interface and fuel pipe is frequently with radial type three-way pipe now
The mode that fittings body coordinates with link bolt realizes that link bolt, which mainly serves, fixes and flow to conducting.But such as Fig. 1 institutes
Show, (3 be composite seal gasket, link bolt 1 to the mode that existing radial type tee pipe coupling body 2 coordinates with link bolt 1
Realization is connect with total member to fix), an only oil duct, and minimum latus rectum is small, circulating resistance is big.
The information for being disclosed in the background technology part is merely intended to increase the understanding to the general background of the utility model, and
It is not construed as recognizing or implying in any form that information composition has been existing well known to persons skilled in the art
Technology.
Utility model content
The purpose of this utility model is to provide a kind of threeway link bolts, have threeway linkage function, latus rectum is big, flow resistance
It is small.
To achieve the above object, the utility model provides a kind of threeway link bolt, including bolt body, bolt body
Top there is extended segment, the outer wall of extended segment to be equipped with external screw thread, there is conical surface interface, conical surface interface to be used for for the inside of extended segment
It is connect with pipe fitting, pipe fitting is taper joint, and the oil duct inside bolt body penetrates through conical surface interface.
Compared with prior art, the utility model has the advantages that：By the way that existing link bolt is changed
It makes, extended segment is set at the top of it, the outer wall of extended segment is equipped with external screw thread, and there is conical surface interface, the conical surface to connect for the inside of extended segment
Mouth is used for connecting with pipe fitting, belongs to integrated structure, while including to be fastenedly connected and lead to function more, at low cost.In addition, this three
The connection matching part of logical link bolt is common vapour mark structure, aspect connection.Peripheral space is saved, arrangement is facilitated.
Description of the drawings
Fig. 1 is the connection structure diagram of existing radial type tee pipe coupling body and link bolt；
Fig. 2 is the structure chart of threeway link bolt according to the present utility model；
Fig. 3 is the use schematic diagram of threeway link bolt according to the present utility model.
Specific implementation mode
Below in conjunction with the accompanying drawings, specific embodiment of the present utility model is described in detail, it is to be understood that this practicality
Novel protection domain is not restricted by specific implementation.
Unless otherwise explicitly stated, otherwise in entire disclosure and claims, term " comprising " or its change
It changes such as "comprising" or " including " etc. and will be understood to comprise stated element or component, and do not exclude other members
Part or other component parts.
As shown in Figures 2 and 3, according to a kind of threeway link bolt 10 of specific embodiment of the present invention, including spiral shell
Bolt ontology 11, the structure of bolt body 11 are similar with the structure of existing link bolt 1, it is important to, in the base of bolt body 11
On plinth, it is equipped with extended segment 14 at the top of bolt body 11, the outer wall of extended segment 14 is equipped with external screw thread, and the inside of extended segment 14 has
There is a conical surface interface 12, conical surface interface 12 is used for connect with pipe fitting 20, and pipe fitting 20 is taper joint, inside bolt body 11
Oil duct 13 penetrates through conical surface interface 12.In this way, threeway link bolt 10 realize connected with oil pipe and it is fixed on the basis of, can be with
Pipe fitting 20 is connected at the top of it, pipe fitting 20 realizes connection by the external screw thread on nut 30 and extended segment 14, and then will pipe
Connector 20 is realized by conical surface interface 12 and is connected.
In said program, by the way that existing link bolt to be transformed, extended segment is set at the top of it, extended segment it is outer
Wall is equipped with external screw thread, and there is conical surface interface, conical surface interface to be used for connecting with pipe fitting, belong to integrated form knot for the inside of extended segment
Structure, while including to be fastenedly connected and lead to function more, it is at low cost.In addition, the connection matching part of the threeway link bolt is normal
With vapour mark structure, aspect connection.Peripheral space is saved, arrangement is facilitated.
To sum up, the threeway link bolt of the present embodiment is arranged by being transformed existing link bolt at the top of it
The outer wall of extended segment, extended segment is equipped with external screw thread, and there is conical surface interface, conical surface interface to be used for connecting with pipe fitting for the inside of extended segment
It connects, belongs to integrated structure, while including to be fastenedly connected and lead to function more, it is at low cost.In addition, the connection of the threeway link bolt
Matching part is common vapour mark structure, aspect connection.Peripheral space is saved, arrangement is facilitated.
The description of the aforementioned specific exemplary embodiment to the utility model is in order to illustrate and illustration purpose.These
Description is not wishing to for the utility model to be limited to disclosed precise forms, and it will be apparent that according to the above instruction, can carry out
Many change and variations.The purpose of selecting and describing the exemplary embodiment is that explaining the specific principle of the utility model
And its practical application, so that those skilled in the art can realize and utilize a variety of different examples of the utility model
Property embodiment and various chooses and changes.The scope of the utility model is intended to by claims and its waits similar shapes
Formula is limited.
