DETAILED DESCRIPTION OF THE PREFERRED EIViBODIMENT
Referring to FIGS. 2A, 2B, and 3, a hose clamp in accordance with one embodiment of the present invention is shown comprised of a binding belt 20 and a screw holder 30 mounted with a screw 10.
The bindiaig belt 20 has a flat head 21, a protruded portion 22 adjacent to the flat head 21, a locating hole 23 formed in the protruded portion 22, a through hole 24 cut through the top and bottom surfaces of the flat head 21, two welding flanges 25 protruded from the bottom surface of the flat head 21 at two opposite lateral sides of the through hole 24, and two stop blocks 26 protruded from the bottom surface of the flat head 21 in front of the through hole 24.
The screw holder 30 comprises t~vo mounting plates 31 symmetrically disposed at two sides. Each mounting plate 31 ~ has a positioning rod 32.
During installation, the screw holder 30 is attached to the top surface of the flat head 21 of the binding belt 20, and then the mounting plates 31 are respectively bent inwards and clamped on the bottom surface of the flat head 21 of the binding belt 20 and stopped between the stop blocks 2b and the protruded portion 22, keeping the positioning rods 32 engaged into the locating hole 23, and then mounting plates 31 are fixedly fastened to the welding flanges 2~ by spot welding. H.
Because the mounting plates 31 of the screw holder 30 are stopped between the stop blocks 26 and the protruded portion 22 and because the positioning rods 32 of the mounting plates 31 are respectively engaged into the locating hole 23 of the binding belt 20, rotating the screw 10 to fasten up the binding belt 20 does not cause the screw holder 30 to break or to disconnect from the flat head 21. Further, because the mounting plates 31 are respectively welded to the welding flanges 25, the screw holder 30 is maintained firmly secu~°ed to the flat head 21 of the binding belt 20.
The hose clamp may be variously embodied. According to the embodiment shown in FIG. 4, there are three stop blocks 26 protruded from the bottom surface of the flat head 21 and transversely aligned in a line in front of the through hole 24.
According to the embodiment shown in FIG. 5, a transverse stop rib 27 is provided at the flat head 21 to substitute for the aforesaid stop blocks 26. According to the embodiment shown in FIG. 6, the two mounting plates 31 of the screw holder 30 each have a welding flange 33 for welding to the flat bottom surface of the flat head 21 of the binding belt 20. According to the embodiment shown in FIG. 7, the binding belt 20 has a series of teeth 28 arranged around the outer (top) sur face thereof for engagement with the screw 10. According to the embodiment shown in FIG. $, the binding belt 20 has a first series of teeth 28 arranged around the outer (top) surface thereof for engagement with the screw 10 and a second series of teeth 29 arranged around the inner (bottom) surface thereof for engaging the peripheral wall of the hose to be affixed.
A prototype of hose clamp has been constructed with the features of FIGS. 2--8. The hose clamp functions smoothly to provide all the features discussed earlier.
Although particular embodiments of the invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited eYCept as by the appended claims.
