Pass through the second end of the second tube body 4.So far the high-speed communication of the first tube body 1 and the second tube body 4 is completed.When being dismantled
When, it is only necessary to the first connector 2 is rotated backward relative to the second connector 3, you can make the first connector 2 and the second connector
3 are detached from fastening state, to complete the dismounting of the first tube body 1 and the second tube body 4.Meanwhile to prevent the first tube body 1 and the second tube body
After 4 connections, because the influence of the factors such as vibrations makes the first connector 2 and the second connector 3 be mutually disengaged, when 2 phase of the first connector
It, can be by spacer pin 6 also cross the first limit hole 23 and the second limit hole after turning to preset position to the second connector 3
33, non-default position is turned to 2 opposite second connector 3 of the first connector of limitation.Prevent the first connector 2 and second from connecting
Fitting 3 is detached from.
Further, in the present embodiment, first connector 2 has multiple first limits of circumferentially spaced configuration
There is the first groove portion 211 and the second groove portion 212, the notch size of the first groove portion 211 to be more than for slot 21, each first limiting slot 21
The notch size of second groove portion 212, and it is in the " [spacing zone of " shape that the second groove portion 212, which has,；Second connector 3 have with
One-to-one multiple first fixture blocks 32 of those first limiting slots 21, and each first fixture block 32 has radially outer first protruded
Joint end 321；Each first joint end 321 can be inserted into therewith during the first connector 2 is axially move closer to the second connector 3
In first groove portion 211 of corresponding first limiting slot 21, and each first joint end 321 can be in the first connector 2 close to second
It is turned to during preset position from the of corresponding first limiting slot 21 with respect to the second connector 3 after connector 3
One groove portion 211 slides into the second groove portion 212, so that the first joint end 321 is connected in the part that the second groove portion 212 is located at spacing zone
On.
When by the first connector 2 and relatively close the second connector 3, the first fixture block 32 can be inserted into the first limiting slot 21
In first groove portion 211.First connector 2 is rotated relative to the second connector 3, the first fixture block 32 is made to enter the first limiting slot 21
In second groove portion 212, at this point, the first joint end 321 of the first fixture block 32 can be matched with the spacing zone of the second groove portion 212, make
First connector 2 and the second connector 3 are fastened togather.When dismounting, contrary operation.
Further, in the present embodiment, first connector 2 further includes multiple second fixture blocks 22, and described second connects
Fitting 3 further includes multiple second limiting slots 31.
Further, in the present embodiment, second tube body 4 is equipped with snap fastener 5, and the snap fastener 5 includes
Snap-latch piece 51 and hasp 52, the snap-latch piece 51 are fixedly installed on the lateral wall of second tube body 4, and the hasp 52 is fixed
It is set on outside support, the hasp 52 cooperates with the snap-latch piece 51, so that the combined pipe and the outside
Holder is mutually fixed.The snap-latch piece 51 is equipped with through-hole, and the hasp 52 includes button 521 and lock body 522, the button 521
It is arranged in the through-hole, the lock body 522 is matched in the button 521, so that the snap-latch piece 51 is in the button 521
It is mutually fixed.The snap fastener 5 is two, and is oppositely arranged on the both sides of 4 lateral wall of the second tube body.
Snap fastener 5 can mutually fix the second tube body 4 with outside support, and the installation of combined pipe is made more to stablize.Meanwhile
Through-hole on snap-latch piece 51 is matched with button 521, can prevent the second tube body 4 from moving in an axial direction, even if the first connection
Part 2 is mutually disengaged with the second connector 3, and the second tube body 4 will not be relatively moved with outside support, make safety coefficient significantly
Increase.
May also set up on first tube body 1 with identical snap fastener 5 on second tube body 4, make combined pipe with
The connection of outside support is more firm.
The foregoing is merely the preferred embodiment of the present invention, are not intended to restrict the invention, for this field
For technical staff, the invention may be variously modified and varied.All within the spirits and principles of the present invention, any made by
Modification, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
