Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a structure for mounting a cover body covering a protruding portion of a handle shaft of a faucet body in a faucet such as a hot and cold water mixing faucet.

[Prior Art] In a faucet such as a hot and cold water mixing faucet or a thermostat mixing valve, a handle for adjusting the amount of hot water to be spouted, the amount of spouted water, or the mixing ratio of hot and cold water is provided. Conventionally, a mounting structure of a cap-shaped cover body covering a base portion of the handle, that is, a handle shaft projecting portion of the water faucet body, is disclosed in, for example, Japanese Utility Model Publication No. 56-37.
There is one disclosed in Japanese Patent No. 175. It was implemented on the handle for adjusting the water discharge temperature of the thermostat mixing valve, but a spring material was fitted into a groove formed on the inner peripheral surface of the cover body (ring body), and the spring material was attached to the faucet body. The cover body is configured to be pressed against the outer circumference of a cylindrical screw body (lid body) screwed to the protruding portion of the handle shaft to prevent the cover body from falling off by the pressure force. However, this known structure has a drawback that the cover body is apt to be loosely attached, and the end edge of the cover body is separated from the faucet body so that the inside can be seen through the gap, which is likely to cause a bad-looking use state.

[Object of the Invention] The present invention solves the above-mentioned drawbacks and provides a mounting structure of a cover body capable of securely concealing the handle shaft protruding portion of the faucet body.

[Means for Achieving the Object] In order to achieve the above object, the faucet cover body mounting structure according to the present invention has a faucet on the outer periphery of a cylindrical screw body screwed to the handle shaft protruding portion of the faucet body. An inclined surface having a small diameter toward the main body side is formed, an inner groove is formed on the inner circumference of a cover body covering the tubular screw body, and a part of a spring ring fitted in the inner groove is formed on the inclined surface. It is characterized in that it is elastically pressed upward so as to be slidable toward the small diameter side.

[Operation] When the spring ring elastically presses the inclined surface, the cover body is biased toward the faucet body side by the reaction force of the inclined surface.
Therefore, the cover body can always be attached tightly without causing a gap at the edge.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. The hot and cold water mixing faucet shown in this embodiment is composed of a horizontal mounting plate 1 on which a water discharge temperature adjusting handle 2 and a water discharge stopping handle 3 are mounted in a protruding manner. A water supply connection port 6, a mixing flow path 7, and a water discharge connection port 8 are formed. The mixing flow path 7, the hot water supply connection port 5, and the hot water supply connection port 6 have a hot water side valve hole 9 and a water side valve hole 10, respectively. Communicating, mixing channel 7 and spout connection 8
And a water discharge valve hole 11 so that they can communicate with each other.
Further, a tubular portion 12 and a tubular portion 13 are provided side by side on the faucet body 4, and female screws 14, 15 and female screws 16, 17 having a larger diameter than these are provided on the inner circumferences of the tubular portions 12, 13, respectively. The male screws 26 and 27 of the handle shafts 18 and 19 are respectively screwed into the female screws 14 and 15 to form the female screw 1.
Cylindrical packing retainers 20 and 21 are screwed onto 6 and 17, and handle shaft 1
8,19 are inserted into the packing retainers 20,21. 22,23
Is a puckkin. A valve body 24 is provided at the inner end of the handle shaft 18 so as to be located between the hot water valve hole 9 and the water valve hole 10. Reference numeral 25 is a shaft seal packing provided between the male screw 26 of the handle shaft 18 and the valve body 24. A water stop valve 28 facing the water discharge valve hole 11 is provided at the inner end of the handle shaft 19. The spout water temperature handle 2 and the spout water stop handle 3 are fixed to the outer ends of the handle shafts 18 and 19 with screws 29 and 30, respectively. Flanges 30 and 31 are integrally formed on the outer circumferences of the bases of the tubular portions 12 and 13, and male screws 32 and 33 are formed ahead of the flanges. The tubular portions 12 and 13 are inserted through the through holes 35 and 36 formed in the mounting plate 1 from below, and are projected onto the mounting plate 1. And the cylindrical screw 37, on the male screw 32, 33,
Screw in 38 and tighten. Numerals 39 and 40 are plate-like packings interposed in the tightening portion. A longitudinal spline groove 41 and an annular outer groove 42 are engraved on the outer peripheral surfaces of the cylindrical threaded bodies 37, 38. As shown in the enlarged view of FIG. 2, the outer groove 42 has a V-shaped cross section and has an inclined surface 42a having a smaller diameter toward the faucet body 4 side. 43 and 44 are cap-shaped cover bodies in which the through holes for the handle shafts 18 and 19 are formed around the cylindrical screw bodies 37 and 38, and the inner peripheral surface of which is a spline groove that matches the spline groove 41. 45 and an annular inner groove 46 are engraved. The inner groove 46 has a U-shaped cross section.
As shown in FIG. 5, a spring ring 47 formed by bending a linear spring material into a rounded square shape is fitted into the inner groove 46. When this is put on the outer circumferences of the cylindrical threaded bodies 37, 38, the intermediate length portion of the four sides of the spring ring 47 slides on the inclined surface 42a of the outer groove 42 toward its smaller diameter side as shown in FIG. Try to press as elastically as possible. By doing so, the reaction force from the inclined surface 42a of the cover bodies 43, 44 works as shown by the arrow b, and the lower end opening edges of the cover bodies 43, 44 can be pressed against the upper surface of the mounting plate 34. . Therefore, the cover bodies 43, 44 can be mounted on the upper surface of the mounting plate 1 without gaps. This does not cause a gap even when the upper surface of the mounting plate 1 is tiled and has irregularities.

By engaging the spline grooves 41 and 45 with each other, the cover bodies 43 and 44 can be non-rotatably fixed to the cylindrical threaded bodies 37 and 38, so that they are discharged onto the outer peripheral surface of the cover bodies as shown in FIG. 4, for example. When the direction of rotation of the handle with respect to the water temperature, the rotation range, or the like is displayed, it is possible to prevent the display position from moving due to the cover body unnecessarily rotating.

In this embodiment, the member screwed on the protruding portion of the handle shaft is a cylindrical screw, but this is not the case.
Needless to say, it may correspond to a lid body screwed to the handle shaft projecting portion as shown in Japanese Patent Publication No. 37175.

[Effects of the Invention] As described above, in the faucet cover body mounting structure according to the present invention, the cover body is biased toward the faucet body side by the spring ring pressing the inclined surface. Can be crimped to the faucet body side such as the mounting plate surface, even if there are some dimensional variations due to molding errors in the cover body or cylindrical screw body, or there is some unevenness on the mounting plate surface etc. Even if it is assembled, the error is absorbed in the range of the inclined surface of the outer groove, and the cover body can be attached without any gap at any time. Even if some external force acts on the cover body to lift it from the surface of the mounting plate or the like, this mounting structure has an advantage that it is naturally corrected by the elasticity of the spring ring and can be mounted without any looseness.
