Abstract
The connector structure includes a tube connector, nuts and sleeves. The tube connector 1 is formed with an intermediate block at an outer middle section and external threads 12 at two ends. An inclined fitting face 13 is formed on inner wall of each end of the tube connector. Each nut 2 has an outer conic surface and an inner conic fitting face 23 at one end. The nut further has inner screw thread 22 on inner wall Each sleeve 3 has an outer conic face 35 at one end and an outer inclined face 34 at the other end. The sleeve 3 is formed with a substantially Z-shaped, U-shaped or V-shaped fissure whereby the sleeve is fitted into the tube connector 1 with the inclined face 34 tightly attached to the inclined fitting face 13 of the tube connector, and the nut 2 is fitted around the conic face 35 of the sleeve with the inner thread 22 engaged with the outer thread 12 of the tube connector so as to tightly attach the conic fitting face 23 of the nut to the conic face 35 of the sleeve. A tube end 4 is inserted into the tube connector and the nut 2 is tightened to contract the fissure of the sleeve 3 so as to tightly hold the tube end 4.
Description
A FAST TUBE CONNECTOR STRUCTURE
The present invention relates to a fast tube connector structure which is able to quickly and easily connect with a circular tube.
A tube connector is widely used to interconnect tubes in various working conditions. Fig. 4 shows a conventional tube connector structure including a sleeve connector 51 for interconnecting two circular tubes 50. Such sleeve connector 51 is unable to accurately interconnect the circular tubes 50 and is subject to loosening and leaking. Fig. 5 shows another conventional tube connector structure in which the circular tubes 50 are formed with outer thread 52 and inner thread 53 engaged therewith to interconnect the tubes 50. According to such measure, the working cost is increased and the working efficiency is reduced. Therefore, it is necessary to provide an improved fast tube connector structure to eliminate the above shortcomings.
It is therefore a primary object of the present invention to provide an improved fast tube connector structure which is able to quickly interconnect two circular tubes without leaking. The fast tube connector structure includes a tube connector, nuts and sleeves. An inclined fitting face is formed on the inner wall of each end of the tube connector.
Each nut has an outer conic edge and an inner conic fitting face at one end. The nut further has inner thread on inner wall. Each sleeve has an outer conic face at one end and an outer inclined face at the other end. The sleeve is formed with a substantially
Z-shaped, U-shaped or V-shaped fissure, whereby the sleeve is fitted into the tube connector with the inclined face tightly attached to the inclined fitting face of the tube connector, and the nut is fitted around the conic face of the sleeve with the inner thread engaged with the outer thread of the tube connector so as to tightly attach the conic fitting face of the nut to the conic face of the sleeve and contract the fissure of the sleeve to tightly hold a circular tube inserted into the tube connector.
The present invention can be best understood through the following description and accompanying drawings, wherein:
Fig. 1 is a perspective exploded view of the present invention;
Fig. 2 is a sectional assembled view of the present invention;
Fig. 3 shows the patterns of the fissures of the sleeves;
Fig. 4 shows a conventional tube connector structure employing a sleeve connector to interconnect circular tubes; and
Fig. 5 shows another conventional tube connector structure employing uoter thread and inner thread to interconnect circular tubes.
Please refer to Figs. 1, 2 and 3. The fast connector structure of the present invention includes a tube connector 1, nuts 2 and sleeves 3.
The tube connector 1 is formed with a stopper block 11 at an outer middle section and outer threads 12 at two ends. An inclined fitting face 13 is formed on inner wall of each end of the tube connector 1, defining an inward tapered inner hole.
Each nut 2 has an outer conic edge 21 and an inner conic fitting face 23 at one end. The inner conic fitting face 23 defines an inward expanded inner hole for fastening the sleeve 3. The nut 2 also has inner thread 22 on inner wall.
Each sleeve 3 has an outer conic face 35 at one end and an outer inclined face 34 at the other end.
The sleeve 3 is formed with a substantially Z-shaped fissure 31, U-shaped fissure 32 or V-shaped fissure 33.
The sleeve 3 formed with the Z-shaped fissure 31,
U-shaped fissure 32 or V-shaped fissure 33 is fitted into the tube connector 1 with the inclined face 34 tightly attached to the inclined fitting face 13 of the tube connector 1. Then the nut 2 is fitted around the conic face 35 of the sleeve 3 with the inner thread 22 engaged with the outer thread 12 to attach the conic fitting face 23 of the nut 2 to the conic face 35. Then a circular tube 4 is inserted into the tube connector 1 and the nut 2 is tightened to fasten the conic fitting face 23 and the inclined fitting face 13 and contract the fissure of the sleeve 3 so as to tightly hold the circular tube 4.
According to the above arrangements, the circular tube can be quickly and easily connected with the tube connector. In addition, the circular tube is tightly held to prevent leakage of water and create an antishock effect. Therefore, the fast connector of the present invention is applicable to all kinds of road working, construction engineering and other special working conditions.
The above description and accompanying drawings are only used to illustrate an embodiment of the present invention, not intended to limit the scope thereof. Any modification or variation derived from the embodiment should fall within the scope of the present invention.
Claims (3)
1. A fast tube connector structure comprising a tube connector, nuts and sleeves, wherein:
the tube connector is formed with a stopper block at an outer middle section and outer threads at two ends, an inclined fitting face being formed on inner wall of each end of the tube connector;
each nut has an outer conic edge and an inner conic fitting face at one end, the nut further having inner thread on inner wall; and
each sleeve has an outer conic face at one end and an outer inclined face at the other end, the sleeve being formed with a substantially Z-shaped fissure, whereby the sleeve is fitted into the tube connector with the inclined face tightly attached to the inclined fitting face of the tube connector, and the nut is fitted around the conic face of the sleeve with the inner thread engaged with the outer thread of the tube connector so as to tightly attach the conic fitting face of the nut to the conic face of the sleeve and tightly hold a circular tube inserted in the tube connector.
2. A fast tube connector structure as claimed in claim 1, wherein the fissure of the sleeve is substantially U-shaped or V-shaped.
