Description

Fitting device of connecting joint horse

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hose joint connection fitting device for a water filter, and in particular, a hose joint fitting fitting for a water filter, which allows the collector cap to support a collet into which the hose is fitted, to be integrally formed with the main body. Relates to a device.

Hose joint fitting device according to the prior art shown in Figure 1 (a),

The hose 1 through which the fluid passes is inserted, the insert plate 2 protrudes on the inner side and the collet 3,

The collet 3 is coupled to the main body 4 (for example, may be composed of a water filter) into which fluid is introduced through the hose 1,

An inclined surface 5 is formed on the inner surface of the main body 4, and when the hose 1 is pushed from the main body 4 by hydraulic pressure or the like, an insert plate (made of metal material) 2 is attached to the inclined surface 5. And a collet cap 6 which presses toward the hose 1 side to prevent detachment,

It is mounted inside the main body 4, and has an O-ring 7 to prevent leakage through the gap between the coupling hole of the main body 4 and the hose (1).

At this time, the contact surface of the injection molded collet cap 6 and the main body 4 is integrally fixed by ultrasonic welding. Therefore, the fixing cost of the collet cap 6 and the main body 4 by the ultrasonic fusion process has the problem that the production cost, work time, production process for ultrasonic fusion is increased.

In addition, fusion residues of foreign matter such as chips are generated at the fusion site, and if chips (chips) are caught between the O-rings (7), leakage occurs due to the occurrence of minute gaps. In other words, due to the total inspection, work time and labor costs are required, resulting in a drop in productivity and a cost increase.

In addition, when a crack is generated due to vibration and impact caused by water pressure, etc. repeatedly generated inside the hose 1 on the fusion portion of the collet cap 6 and the main body 4, there is a problem of leaking through the crack part.

That is, when the injection molded collet cap 6 is forcibly pressed into the opening inner surface of the main body 4, the collet cap 6 is coupled to the opening of the main body 4 by the insert plate 8, By (3), the detachment of the hose 1 from the main body 4 can be prevented.

At this time, since the insert injection molding the above-mentioned collet cap 6, the cost cost is relatively increased compared to the ultrasonic welding method. In addition, by forcibly pressing the collet cap 6 into the opening of the main body 4, the insert plate 8 is folded in the production process to increase the failure rate. As a result, productivity is lowered, resulting in a cost increase.

In the embodiment of the present invention, since the ultrasonic welding process for fixing the collet cap supporting the collet to the main body, the insert injection process of the collet cap, etc. are unnecessary, the integers can be reduced to reduce the cost incurred in manufacturing costs Related to hose joint fittings for filters.
