Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-5 is please referred to, a kind of embodiment provided by the utility model: a kind of circular tube connection structure, including main body 2,
One round tube 3, die casting 7 and the second round tube 9, the bottom end of main body 2 is mounted on pedestal 4, and is horizontally installed with first between main body 2
Round tube 3, the side of the first round tube 3 is provided with preformed hole 5, and the inside of preformed hole 5 passes through the first machine-processed rice screw 6 and is equipped with
The longitudinal section of clip 1, clip 1 is arc-shaped, and the diameter of clip 1 is greater than the diameter of the first round tube 3, convenient for clip 1 is stuck in the
On one round tube 3, so that connection is more beautiful, it is provided with nut 16 on the first machine-processed rice screw 6, so that nut 16 can be by card
Fixedly more fastening and beauty, clip 1 is respectively and fixedly provided with die casting 7 far from the side of preformed hole 5 between hoop 1 and the first round tube 3,
And die casting 7 is provided with groove 12 close to the side of clip 1,7 bottom end of die casting is equipped with sliding block far from the side of groove 12
8, being integrally formed welding structure between sliding block 8 and die casting 7, guarantee to connect between sliding block 8 and die casting 7 it is stronger,
The inside of first machine-processed rice screw 6 is mounted on first connecting rod 13, and it is fixed that 7 top of die casting is provided with close to the side of groove 12
Position hole 11, the outside of die casting 7 is equipped with the second round tube 9, and the top of the second round tube 9 is provided with through-hole 10, the first round tube 3
Inside with the second round tube 9 is hollow structure, reduces the production cost of enterprise, and the inside of through-hole 10 and location hole 11 is all provided with
It is equipped with the second machine-processed rice screw 14, and the inside of the second machine-processed rice screw 14 is mounted on the second connecting rod 15, through-hole 10 and location hole
There are two 11 number is respectively set, and the vertical center line of through-hole 10 and location hole 11 about the second round tube 9 is symmetrical,
And the center line of through-hole 10 and location hole 11 overlaps, and is evenly arranged on the inner sidewall of through-hole 10 and location hole 11 interior
Screw thread, to guarantee that the second machine-processed rice screw 14 can sequentially pass through the inside that through-hole 10 is screwed into location hole 11.
Working principle: in use, by being respectively provided with pedestal 4 in the bottom end of main body 2, and the bottom end of pedestal 4 be provided with it is anti-
Skidding, so that the case where main body 2 facilitates fixation when in use, avoids the occurrence of sliding, is successively stuck in first for clip 1 later
The side of round tube 3, and successively spiral shell is into inside the preformed hole 5 on the first round tube 3 by the first machine-processed rice screw 6, followed by nut 16
It is locked, so that connection ground more fastens between clip 1 and the first round tube 3, first connecting rod 13 is then injected into the first machine
