The specific embodiment
Below in conjunction with accompanying drawing the utility model is carried out detailed description:
As shown in Figure 1, sweat soldering comprises locking device 1, fixed head 2 and two second screws 3 with the fixture of plumb joint.Locking member device 1 is removably mounted on the fixed head 2 through two second screws 3.
As depicted in figs. 1 and 2, locking device 1 comprises the locking member 11 and first screw 12.Locking member 11 is cylindrical.Locking member 11 is provided with first through hole 13.First through hole 13 is provided with internal thread.First through hole, 13 self-locking parts, 11 upper surfaces 14 extend to the lower surface (not shown).Be provided with groove 15 around first through hole 13.Groove 15 self-locking parts 11 upper surfaces 14 extend to lower surface, just extend axially along first through hole 13.Groove 15 is an arc, is provided with around first through hole 13.The edge 16 that locking member 11 is provided with self-locking part 11 extends to first through hole 13 and axially runs through first breach 17 of locking member 11 along first through hole 13.Extend axially along first through hole 13, just self-locking part 11 upper surfaces 14 extend to lower surface.First breach 17 merges first through hole, 13 closures; First breach 17 is opened, and first through hole 13 opens.Be that first breach 17 is opened shown in Fig. 2, first through hole, 13 open states just.Locking member 11 has the plane 18 parallel with first breach 17, and just the edge 16 of plane 18 self-locking parts 11 extends to first through hole, 11 directions, and the upper surface 14 of self-locking part 11 extends to lower surface.Plane 18 is provided with first internal thread hole 19.First internal thread hole 19 extends to said first breach 17.The locking member 11 of first breach, 17 opposite sides is provided with the second internal thread hole (not shown).Second internal thread hole is relative with first internal thread hole, 19 positions.The second internal thread hole axis and first through hole, 13 axis normal.First screw 12 and first internal thread hole 19 and the second internal thread hole threaded engagement.
Like Fig. 1 and shown in Figure 3, third through-hole 21 and two the 3rd internal thread holes 22 are set on the fixed head 2.Two second screws 3 pass groove 15, are screwed in the 3rd internal thread hole 22.Two second screws 3 are removably mounted on locking member 1 on the fixed head 1.Third through-hole 21 is relative with first through hole, 13 positions.
Fig. 4 is the fixture user mode sketch map in the utility model.Shown in Fig. 1-4, plumb joint 4 passes first through hole 13 of locking member 1.Utilize first screw 12 to be screwed in first internal thread hole 19 and second internal thread hole, make first breach, 17 closures.Locking member 1 clamps plumb joint 4.Make plumb joint 4 pass the third through-hole of fixed head 2 again.Rotation lock part 1 can be adjusted the direction of plumb joint 4, makes its direction meet instructions for use.Use two second screws 3 to pass groove 15 and be screwed in the 3rd internal thread hole 21, locking member 1 is fixed on the fixed head 2.Owing to be provided with groove 15, so rotation lock part 1 no matter how can both adopt second screw 3 fixing after rotation easily.Then the second nut (not shown) is screwed on the plumb joint 4, makes second nut be adjacent to fixed head 2 lower surfaces, utilize the locking member 1 and second nut that plumb joint 4 is fixed on the fixed head 2.Because locking member 1 is fixing by two second screws 3, locking member 1 clamps plumb joint 4, and therefore when turning second nut, plumb joint 4 rotation can not take place.In fixation procedure, plumb joint 4 directions can deflection.
As shown in Figure 5, the difference of itself and embodiment 1 is that present embodiment is installed with hex nut 5 with on the basis of embodiment 1 on locking member 1.The through hole 51 of hex nut 5 aligns with first through hole 13.Hex nut 5 is provided with second breach 52.Second breach 52 aligns with first breach 17.In first through hole 13 internal thread is not set.
The present embodiment occupation mode is identical with embodiment 1.
In the present embodiment, owing to adopt the hex nut 5 that second breach 51 is set, it can be opened or closure through first screw 12 equally.Setting still can overcome the problem that fixture of the prior art is brought because of expanding with heat and contract with cold like this.With respect to embodiment 1, adopt hex nut 5 in the present embodiment, need not machining internal thread in first through hole 13, the locking member manufacturing in the present embodiment is more prone to.
Hex nut 5 also can adopt the nut of round nut or other shape.
The difference of itself and embodiment 1 is that the 3rd internal thread hole 21 changes through hole into, no internal thread in it.Adopt the bolts and nuts combination to replace second screw 3.
With respect to embodiment 1, present embodiment need not to adopt the 3rd internal thread hole 21, only needs the processing through hole to get final product, and the manufacturing of locking member is more prone to.
Present embodiment also can make up with embodiment 2.
The present embodiment occupation mode is identical with embodiment 1.
Embodiment in the utility model only is used for the utility model is described, and does not constitute the restriction to the claim scope, and other substituting of being equal in fact that those skilled in that art can expect are all in the utility model protection domain.
