Specific implementation mode
For a clearer understanding of the technical characteristics, objects and effects of the present invention, now control illustrates this hair
Bright specific implementation mode.
As shown in Figures 1 to 6, the present invention provides a kind of compound holding screw 100；Include as threaded connection part
Silk plug portion 1 and as the contact part 2 for compressing position portion, contact part 2 and silk plug the portion 1 seperated and Detachable connection structure of use are set
Meter, contact part 2 are removedly connected in the one end in silk plug portion 1；Silk plug portion 1 is with contact part 2 respectively by two different material structures
At being arranged connection screw thread in silk plug portion 1, concave hole 11 is arranged in the one end in silk plug portion 1, and concave hole 11 can be that through-hole can also be
The aperture of blind hole, concave hole 11 is D, and torque transfer arrangement is arranged in the other end in silk plug portion 1；Contact part 2 close to silk plug portion 1 one
End setting can be installed on the outer lug boss portion 21 in concave hole 11, and the outer diameter in outer lug boss portion 21 is d, in the present embodiment, evagination
Platform portion 21 is cylinder boss；One end setting tightening supporting part 22 of the contact part 2 far from silk plug portion 1.The compound tightening of the present invention
The silk plug portion of screw 100 and contact part are removedly connected, and facilitate the material cell using different demands, have interchangeability,
In practical application, according to operating mode difference, the difference of fixed member can select different material cells to make, give full play to not
The advantages of with material, and then can realize and be dielectrically separated from while realizing that high intensity securely connects, contact surface protection
Etc. functions, reliability of positioning it is high；The compound holding screw 100 of the present invention is simple in structure, easy to make, applied widely,
Conducive to promoting the use of.
Further, in practical applications, according to operating mode difference, the difference of fixed member can select different bills of materials
Member makes silk plug portion 1 and contact part 2.Contact part can be made of metal material unit, and contact part can also be by nonmetallic materials
Unit is constituted.Since the physical and chemical performance (magnetic conductivity, conductivity, resistance to corrosion etc.) of different materials is different, Young's modulus
Difference resists deformability difference, can select metal material, nonmetallic materials, insulating materials, high-ductility as needed
Material meets the needs of actual condition.In the specific embodiment of the present invention, the silk plug portion 1 of compound holding screw is by excellent
Matter steel alloy is made, and contact part 2 is made of engineering plastics (ABS).
Further, the tightening supporting part 22 of contact part 2 be bulb globoidal structure (bulb shape, as shown in Figures 1 to 6) or
Concrete shape for column planar structure, tightening supporting part 22 is determined according to fixed member is wanted.
Further, silk plug portion 1 is different with the material of contact part 2, and coefficient of thermal expansion is different, between silk plug portion 1 and contact part 2
Connection matching relationship also differ, as shown in Fig. 2, setting the outer diameter in outer lug boss portion 21 as d, the aperture of concave hole 11 is D, outside
Matching relationship (matching relationship of d and D) between boss portion 21 and concave hole 11 can be clearance fit, transition cooperation or mistake
It is full of cooperation.When outer lug boss portion 21, interference fit is connected in concave hole 11, in contact part 2 from one end close to silk plug portion 1 to
Buffering blind hole 23 is inside opened up, outer lug boss portion 21 is buffered blind hole 23 and make outer lug boss portion 21 more by the squeezing action of concave hole 11
It fits easily in concave hole 11.
Further, torque transfer arrangement is made of the tool fastening groove 12 opened up on the end face of the other end in silk plug portion 1.Such as
Shown in Fig. 3, Fig. 4, Fig. 5, Fig. 6, in the present embodiment, the cross section of tool fastening groove 12 can be regular hexagon, square,
It is linear type, cross or star-shaped, correspondingly, the tool for tightening compound holding screw 100 can be allen wrench, a word spiral shell
Silk knife, Phillips screwdriver etc..
When silk plug portion 1 and contact part 2 are made of metal material unit, the mechanical processing (side such as turning, milling may be used
Formula) mode manufactured；It, can be by pressure forming (note when silk plug portion 1 and contact part 2 are made of non-metallic material material unit
Modeling, casting etc. modes) mode manufacture.When the matching relationship of d and D is clearance fit, directly by the outer lug boss portion of contact part 2
21 are inserted into the concave hole 11 in silk plug portion 1, you can realize the assembling of silk plug portion 1 and contact part 2；When the matching relationship of d and D are
When transition coordinates or is interference fitted, the outer lug boss portion 21 of contact part 2 is pressed in the concave hole 11 in silk plug portion 1 and (needs to apply
Add certain pressing force), you can realize the assembling of silk plug portion 1 and contact part 2.
In the specific embodiment of the present invention, compound holding screw 100 is applied in industrial gas oil tubing string,
As shown in Fig. 7, Fig. 8, Fig. 9, lantern ring 91 (prior art) is fixed on the outside of steel pipe 92, steel pipe by compound holding screw 100
Certain radial clearance is kept between 92 outer wall and the inner wall of lantern ring 91.The silk plug portion 1 of compound holding screw 100 is by high-quality
Steel alloy is made, and contact part 2 is made of engineering plastics (ABS), can play insulating effect.The silk plug portion 1 of metal material can protect
The high intensity demonstrate,proved between compound holding screw 100 and lantern ring 91 securely connects；Since engineering plastics are low compared with metal material hardness,
Contact part 2 will not cause mechanical wounding to steel pipe 92；Simultaneously because engineering plastics have better ductility compared with metal material,
Screw thread screws contact part 2 under force effect and deforms, and improves the contact area of compound holding screw 100 and steel pipe 92, it is ensured that
The reliability that compound holding screw 100 positions.
From the above mentioned, compound holding screw provided by the invention has the advantages that：
The silk plug portion of the compound holding screw of the present invention and contact part are removedly connected, and are facilitated using different demands
Material cell has interchangeability, and in practical applications, according to operating mode difference, the difference of fixed member can select different materials
Material unit makes, the advantages of giving full play to different materials, and then can be realized while realizing that high intensity securely connects
Be dielectrically separated from, functions, the reliability of positioning such as contact surface protection it is high；The compound holding screw of the present invention is simple in structure, makes
It is convenient, it is applied widely, conducive to promoting the use of.
