Brief description of the drawings
Fig. 1 is the vertical profile sectional view of rotary fast connecting joint of the invention.
Embodiment
As shown in figure 1, the rotary fast connecting joint of the present invention includes the upper shell 1 and lower house 9 being threadedly coupled mutually,
Upper shell 1, lower house 9 all have chamber；Circle ring part is installed with upper shell 1, circle ring part includes at least one circle gold
Belong to ring, the connected wire 20 of welding metal rings is open from upper shell 1 to be stretched out；Insulation board 10 is installed with lower house 9, is insulated
The guide cylinder 12 of metal material is installed with plate 10, the wire 11 that guide cylinder 12 is weldingly connected is open from lower house 9 to be stretched out,
The spring 13 of metal material is installed, the one end of spring 13 is connected and the other end and metal branch with the bottom of guide cylinder 12 in guide cylinder 12
Frame 14 is connected, and metallic support 14 does stretching motion together with spring 13 along the axis of guide cylinder 12, and the effect of guide cylinder 12 is to make
Metallic support 14 and spring 13 are moved along a straight line with the direction perpendicular to metal ring surface all the time, and metallic support 14 stretches out guide cylinder
The rolling member of metal material is installed on 12 part；Often circle becket is relative with a corresponding rolling member, so that
Upper and lower casing 1,9 is screwed in process (be spirally connected process), and each rolling member moves (as rolled) along corresponding becket,
And after upper and lower casing 1,9 is screwed in place, each rolling member under the effect of spring 13 corresponding becket tight against
Top.
Such as Fig. 1, circle ring part may include insulating core 2, and at least one circle metal is outwards arranged with from the neighboring of insulating core 2
Ring, often enclose becket neighboring provided with one circle dead ring, that is to say, that when be designed with it is some circle becket when, becket with
Dead ring is radially arranged at intervals from inside to outside, and the dead ring in outmost turns is mutually fixed with upper shell 1.
Normally, insulating core 2 is cylindrical, and becket is to be coaxially disposed between annular shape, their threes with dead ring.Enter
For one step, it is mutually positioned between insulating core 2, becket and dead ring by the spacing shaft insulation 18 worn jointly, to ensure
Do not occur relative displacement between three in the axial direction, do not relatively rotated in radial direction.
In actual design, becket is excellent conducting metal, for example, can be made up of silver, copper, gold, aluminium or iron material matter,
It is without limitations.The material of upper and lower casing 1,9 is without limitations.
In actual design, rolling member may include the metal material wheel shaft 16 being arranged on metallic support 14, wheel shaft 16
On rotatable Metal Contact Rollers 15 are installed, as shown in Figure 1.
In addition, rolling member may also comprise metal balls or metal roller bearing on metallic support 14 (in figure not
Show).
Certainly, any part that can occur rolling effect all can be as the rolling member in the present invention, and its structure can be each
Various kinds is planted, it is without limitations.
Inventive joint can be used as the ordinary couplings in routine use, certainly, if passing through between upper shell 1 and lower house 9
If a pair of flame proof thread pairs are attached, then the flame proof joint in explosive hazard environment is can be used as.
The situation for being arranged in order three beckets from inner ring to outer ring since insulating core 2 is shown in such as Fig. 1, figure, i.e.,
First becket 3, the second becket 5, the 3rd becket 7, the neighboring of each becket are provided with a circle dead ring, i.e., and
The neighboring of one becket 3 is provided with the first dead ring 4, and the neighboring of the second becket 5 is provided with the second dead ring 6, the 3rd metal
The neighboring of ring 7 is provided with the 3rd dead ring 8.Herein, becket is spaced with dead ring.Also, it is exhausted in outmost turns
Edge ring --- the 3rd dead ring 8, is mutually fixed by screw 17 with upper shell 1.First becket 3, the second becket 5, the 3rd gold medal
The wire 20 being connected with outside respective electric equipment is respectively welded on category ring 7.
Accordingly, three guide cylinders 12 are inlaid with the insulation board 10 in lower house 9, three guide cylinders 12 are respectively with
First, second, third becket 3,5,7 is corresponded.The installation site of guide cylinder 12 should be reasonable according to the principle not interfered with each other
Design.The wire 11 being connected with outside respective electric equipment is respectively welded on each guide cylinder 12.Spring in each guide cylinder 12
It is provided with 13 connected metallic supports 14 on metal wheel shaft 16, wheel shaft 16 and rotatable Metal Contact Rollers 15 is installed.
When upper and lower casing 1,9 is screwed, each roller 15 is moved along with respective corresponding becket.When upper and lower casing 1,
After 9 screw in place, each roller 15 under the elastic force effect of spring 13 tight against withstand on (three on respective corresponding metal ring surface
Individual roller 15 respectively with the close contact of first, second, third becket 3,5,7), so as to form 3 tunnel power transmission loops.The electricity per road
Force signal via wire 20, becket, the roller 15 with the becket phase close contact, wheel shaft 16, metallic support 14, spring 13,
Guide cylinder 12, one transmission loop of the formation of wire 11.
It is an advantage of the invention that：
1st, inventive joint only by screwing between upper and lower casing just can realize its roll inside part and becket it
Between close contact, so as to realize quick connection and the transmitting of electric power signal of both sides wire, cost is low, service life
It is long.
1) rolling member can be again unlikely to too to oppress metal by spring flexibly tight against withstanding on metal ring surface
Ring, this elastic close contact can avoid becket because of rolled portion while ensuring that all rolling members are all reliably connected, again
The direct of part is supported and is damaged firmly.If not using this mode of spring, then influenceed, just there may be by machining accuracy
Rolling member is sturdy with becket, but the situation in gap is still suffered between other rolling members and becket, so that can not
Ensure effective, reliable power transmission.
2) use of rolling member causes upper and lower casing during screwing, rolling member in a rolling manner with gold
Category ring rubs, and this roll mode is difficult to cause scuffing etc. to damage metal ring surface.If not using rolling member, that
During upper and lower casing is screwed, metal ring surface can caused to screw by this kind of non-rolling friction of such as sliding friction
While resistance increases, non-rolling friction effect can cause cut to metal ring surface, so that after being dismounted for multiple times, the shadow of cut
Ring meeting and then cause the generation of signal loose contact problem.
2nd, in the present invention, upper and lower casing is connected using thread forms, and the wire on both sides passes through rolling member and becket
Be close to and realize electrical communication, whole attachment structure is easy and effective, and contained part is few, make difficulty of processing it is low, make precision
Easily ensure, while quick linkage function is realized, electric power signal transmission reliability can obtain sound assurance.
3rd, the present invention can be used as the ordinary couplings in daily occasion, also can be used as blast by the secondary design of flame proof thread
Flame proof joint in hazardous environment.
The technical principle described above for being present pre-ferred embodiments and its being used, comes for those skilled in the art
Say, without departing from the spirit and scope of the present invention, any equivalent transformation based on the basis of technical solution of the present invention,
Simple replacement etc. is obvious to be changed, and is belonged within the scope of the present invention.
