Shape situation.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of on-deformable double end spiral shells
Nail.
To achieve the above object, the utility model provides following technical solution: a kind of dowel screw, including rivet nut,
Be characterized in: the rivet nut is divided into swivel head, lower swivel head and connecting rod, and connecting rod is placed between swivel head and lower swivel head
And respectively with upper swivel head and lower swivel head integrally connected, the upper swivel head is equipped with the first screw thread, and lower swivel head is equipped with
Second screw thread, first screw thread and the second screw thread all extend on connecting rod outer wall, and the connecting rod outer wall is equipped with traction
Ring block, the bail block and connecting rod integrally connected, the bail block outer wall are equipped with several through-holes, and through-hole extends to
In connecting rod, draw bar is equipped in the through-hole, the draw bar outer wall is equipped with third screw thread, and bail block side is also
It is formed between the first head of screw of arrangement, the first adjacent head of screw equipped with several using connecting rod as center circular rings and dissipates power
Space, the bail block other side are equipped with second head of screw opposite with scattered power space, first head of screw and the second head of screw
Contradicted with draw bar.
By using above-mentioned technical proposal, first by the design of the bail block outside connecting rod, mentioned using bail block
High whole intermediate intensity, recycles bail block outer wall that several through-holes are arranged, draw bar is directly screw-inserted into through-hole,
One until realize internal filling, and when there is internal rotating power, can guarantee that power can be passed quickly in connecting rod
It is handed to outside, then cooperates the first head of screw and the second head of screw on bail block, the suffered power of draw bar is led to traction
Outside ring block, and realize the component of staggered, and with annular pattern, arrangement realizes that circumference dissipates power, realize internal endurance it is few and
Quickly scattered power effect, to guarantee to avoid the occurrence of deformation inside it.
The utility model is further arranged to: component bar is additionally provided among the draw bar, component bar surface is equipped with
The raised line of several arcs, the raised line are stuck on draw bar.
By using above-mentioned technical proposal, it is equipped with component bar using inside, achievement unit component can quickly be dissipated from component bar
Power to avoid the concentration of internal rotating power, and then reduces internal modification situation and occurs, and cooperate the raised line of arc, in realization
Portion's intensity is reinforced.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Fig. 2 is the component rod structure schematic diagram of the utility model embodiment.
Specific embodiment
The utility model embodiment is described further referring to figs. 1 to Fig. 2.
A kind of dowel screw, including rivet nut, it is characterized in that: the rivet nut is divided into swivel head 101,201 and of lower swivel head
Connecting rod 501, connecting rod 501 be placed between swivel head 101 and lower swivel head 201 and respectively with upper swivel head 101 and backspin
201 integrally connected of rotary head, the upper swivel head 101 are equipped with the first screw thread 102, and lower swivel head 201 is equipped with the second screw thread
202, first screw thread 102 and the second screw thread 202 all extend on 501 outer wall of connecting rod, set on 501 outer wall of connecting rod
There are bail block 301, the bail block 301 and 501 integrally connected of connecting rod, if 301 outer wall of bail block is equipped with
Dry through-hole, through-hole extend in connecting rod 501, and draw bar 302 is equipped in the through-hole, is set on 302 outer wall of draw bar
There is third screw thread 303, it is center circular rings around arrangement that 301 side of bail block, which is additionally provided with several with connecting rod 501,
First head of screw 401 forms between the first adjacent head of screw 401 and dissipates power space 601,301 other side of bail block be equipped with
Dissipate opposite the second head of screw 502 in power space 601, first head of screw 401 and the second head of screw 502 with draw bar 302
It contradicts.
By using above-mentioned technical proposal, first by the design of the bail block 301 outside connecting rod 501, traction is utilized
Ring block 301 improves whole intermediate intensity, recycles 301 outer wall of bail block that several through-holes are arranged, and draw bar 302 is direct
It is screw-inserted into through-hole, one fills up in connecting rod 501, realization is internal, and when there is internal rotating power, can
Guarantee that power can quickly be transferred to outside, then cooperate the first head of screw 401 and the second head of screw 502 on bail block 301,
