Description

[Detailed description of the invention] (Field of industrial application) This invention belongs to the field of water distribution equipment, and is used when an antifreeze faucet installed outdoors is opened or closed by remote control from indoors. Used as a snow cover for the remote control unit.

(Prior art) Anti-freeze faucets traditionally used to prevent freezing can be operated remotely from indoors even when installed outdoors; Because the power transmission mechanism of the unit is exposed, when snowfall increases, there is a risk of accidents such as falling snow from the roof, falling icicles, or deformation or damage of the remote control unit due to external forces such as snow compaction loads. There is a demand for measures to prevent snow damage.

(Problems to be Solved by the Invention) In view of the above circumstances, the technical problem of the present invention is to provide a snow cover that protects a remote control unit from snow damage.

(Means for Solving the Problems) In order to solve the above problems, the present invention sets the axis that bisects the angle formed by the intersecting axes as an axis of symmetry, and symmetrically about the axis, the thick part of the half-split joint surface A convex fitting edge and a concave fitting edge are arranged, a storage space is formed at the intersection of the intersecting shafts, and the storage space is provided at each end of the convex fitting edge and the concave fitting edge. Elbow a consisting of a combination of half-split elbows that communicate with the arranged arc part
and a cylindrical tube b formed by a combination of half cylinders having a convex fitting edge and a recess fitting edge arranged at both ends of the joint of the half cylinders.

(Function) According to the above configuration, both the elbow a and the cylindrical tube b have a half-split structure, and the convex fitting edge and the concave fitting edge, which are dimensioned so that they can fit into each other across the axis of symmetry, are arranged on their joint surfaces. In terms of production, mass production can be carried out using a single half mold, and in terms of functionality, it is easy to assemble into an existing remote control unit.Furthermore, the joint part has a water-draining effect due to the concave-convex fitting, making it possible to prevent internal remote control. Durably protects the operating section.

(Example) To explain the present invention in detail with reference to an example, as shown in FIG. The axis that forms an angle of 45° is the axis of symmetry 2,
A convex fitting edge 3 is arranged on the upper part symmetrically with respect to the axis 2,
A concave fitting edge 4 is provided at the bottom, a storage space 5 is formed at the intersection of the orthogonal axes, and the storage space 5 is formed at each end of the convex fitting edge 3 and the concave fitting edge 4. The joint seats 7 and 7' are disposed on the left and right sides of the outer periphery of each arcuate portion 6, respectively.
The two identical half elbows 1 constructed in this manner have one protrusion fitting edge 3 engaged with the other concave fitting edge 4, and the other protrusion fitting edge 3 being engaged with the other concave fitting edge 4. It consists of a fitting of a drainage structure that engages with the joint edge 4,
At this time, the joining seats 7 horizontally installed on the left and right sides of the outer periphery of the circular arc portion 6 of one convex part fitting edge 3 with their upper surfaces aligned with the lower bottoms of the convex part fitting edge 3 are attached to the other concave part fitting edge 4. Jointing seats 7' are placed horizontally on the left and right sides of the outer circumference of the arcuate portion 6, with their upper surfaces matching the top surfaces of the recessed fitting edges 4, and are closely joined, and the joining seats 7, 7' can be joined with screws. This forms an elbow a. The cylindrical tube b that engages with the arcuate portion 6 of the elbow a is composed of a combination of half cylinders 8 shown in FIG. A recessed part fitting edge 1 having a convex part fitting edge 9 disposed thereon and having a dimension on the other side to engage with the convex part fitting edge 9.
0, the convex fitting edge 9 of one half cylinder 8 is engaged with the concave fitting edge 10 of the other half cylinder 8, and the convex fitting edge 9 of one half cylinder 8 is engaged with the concave fitting edge 10 of the other half cylinder 8. The edge 9 is engaged with one of the recessed fitting edges 10, and both are fixed with a tightening band 11. As shown in Fig. 3, the elbow a and the cylindrical pipe b are used as a snow cover by housing the remote control unit of the antifreeze faucet remote control device, and the elbow a is used as a snow cover.
A cylindrical tube b, which is fitted into the arc portion 6 of the elbow a, covers the rotating shaft 13 and protects it from snow damage caused by external forces such as falling snow, falling icicles, or snow compaction loads. In addition, when connecting a plurality of cylindrical tubes b, the joint surfaces of the side edges of the half cylinders are staggered from each other and connected.

(Effect of the invention) As described above, according to the invention, since the elbow a is also a halved cylindrical pipe b with a drainage structure, the remote control part of the existing antifreeze faucet can be easily and durable protected. In addition, it can be mass-produced using one half-mold, so it has the advantage of being extremely economical.
