The present invention relates to a hose connector, and more particularly to an improved hose connector.
A conventional hose connector structure, please refer to
It is not difficult to find out that the above-mentioned conventional structure has some shortcomings. The main reason is as follows: The outer circumference of the tightening ring 70 is a convex arc-shaped outer wall, which does not provide any positioning effect for the hose assembly, so that the tightening ring 70 is easily detached from the connecting bolt 60 causing inconvenient to install. In addition, the installation time and labor costs are increased.
Therefore, it is desirable to provide a hose connector to mitigate and/or obviate the aforementioned problems.
An objective of present invention is to provide a hose connector, which is capable of improving the above-mention problems.
In order to achieve the above mentioned objective, a hose connector has: a head portion, at least one connecting bolt, and a tightening ring. The head portion has a flow channel with at least two open ends, and at least one of the open ends is provided with a threaded portion. The connecting bolt has an inner threaded section engaging the threaded portion of the open end of the head portion, an opening of the connecting bolt has a stopping portion. The tightening ring has a groove configured to accept the stopping portion, a clasping end is formed adjacent to an outer edge of the groove and engaging an outer wall of the stopping portion, a convex ring is formed at another end of the tightening ring and pushing against the stopping portion.
Other objects, advantages, and novel features of invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

For the assembly of the structure and the state of actual use, please refer to
In summary, when the structure is actually used, the hose 40 is inserted from the connecting bolt 20 and enters through the tightening ring 30 into the flow channel 11 of the head portion 10. After the hose 40 is tightly fitted through the tightening ring 30, and the connecting bolt 20 is locked with the head portion 10. Since the tightening ring 30 is accommodated in the connecting bolt 20 without inferring contact, the hose 40 and the connecting bolt 20 are prevented from forming a synchronized rotation state. While the connecting bolt 20 is locked it also pushed the tightening ring 30 toward the open end 12, and then gradually introduces the tapered surface 34 closer to the chamfer 121 of the open end 12. Therefore, the tightening ring 30 and the open end 12 of the head portion 10 are positioned, and the tightening effect between the head portion 10 and the connecting bolt 20 is achieved through the tightening ring 30, which completes the assembly.
According to another embodiment of the structure, as shown in
With the structure of the above-described embodiment, the following benefits can be obtained: the groove 31 of the tightening ring 30 accepts the stopping portion 22 of the connecting bolt 20, and the clasping end 32 engages with the stopping portion 22 at the outer wall while positioning the convex ring 33 against the stopping portion 22. Therefore, the tightening ring 30 is fixed onto the connecting bolt 20 to avoid the tightening ring 30 from falling off the connecting bolt 20 and increases the convenience of the assembling work for the tubular body 40. In addition, the tightening ring 30 forms an no-contact state through the groove 31 and the connecting bolt 20, so that the hose 40 does not rotate with the connecting bolt 20, which greatly increases the installation speed and reduces the labor cost.
Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of invention as hereinafter claimed.
