Hereinafter, embodiments of the present invention will be described with reference to FIGS.
As shown in FIG. 1, the drip hanging tool of the present invention includes an attachment member 1, a lock ring 2, a hook member 3 and a cover 4.
[0011]
The mounting member 1 is made of a hard synthetic resin and includes a base portion 5 and a connecting portion 6. The base portion 5 has a disk shape, an engagement groove 7 is formed on the outer peripheral edge thereof, and a mounting hole 8 is provided in the center. The connecting portion 6 includes connecting pieces 9 and 9 and protrudes downward from the base portion 5. The connecting piece 9 is formed in a semi-cylindrical shape in which a cylinder is divided into two along an axis, and is opposed to each other with an appropriate interval 10 to constitute a cylindrical connecting portion 6. In the illustrated case, the connecting portion 6 is composed of two connecting pieces 9, but three or more connecting pieces 9 may be arranged in a cylindrical shape to form the cylindrical connecting portion 6.
[0012]
The upper end portion 11 at which the connecting piece 9 is joined to the base portion 5 is formed to have a narrower width in the circumferential direction than the lower portion by a cut 11 ′ (see FIG. 2). This is because the connecting pieces 9 and 9 are easily elastically deformed in the reduced diameter direction of the cylindrical connecting portion 6.
[0013]
On the inner periphery of the lower end portion of the connecting piece 9, an inner peripheral engaging protrusion 12 is formed inward of the connecting portion 6. The cross section of the inner peripheral engagement protrusion 12 is formed in a trapezoidal shape with the upper surface and the lower surface 13 inclined, and the lower edge of the lower surface 13 reaches the lower end of the connecting piece 9.
[0014]
A locking protrusion 14 having a triangular cross section is formed on the outer periphery of the lower end portion of the connecting piece 9, and the upper surface thereof is horizontal and the lower surface is inclined downward. A lock outer peripheral surface 15 is provided on the outer periphery immediately above the locking ridge 14, and the unlock outer periphery having an outer diameter smaller than the lock outer peripheral surface 15 is provided above the lock outer peripheral surface 15. A surface 16 is formed. A rib 17 is formed on the outer periphery of the central portion of the unlock outer peripheral surface 16. The diameter of the top of the rib 17 is substantially equal to the outer diameter of the lock outer peripheral surface 15. Further, a restriction projection 18 is provided on the outer surface of the upper end portion 11.
[0015]
Next, the lock ring 2 is a cylindrical body having upper and lower ends made of hard synthetic resin, and an outward flange 19 is formed at the lower end. The flange 19 reinforces the lock ring 2 and has a function of improving the catching of the operator's finger during the mounting operation. The inner diameter is substantially equal to the diameters of the lock outer peripheral surface 15 and the tops of the ribs 17 and is fitted to both of them without a gap. Further, the height is substantially equal to the distance between the upper surface of the locking protrusion 14 and the lower surface of the restricting protrusion 18 and fits between the two without any gap.
[0016]
When the lock ring 2 is forcibly engaged with the connecting portion 6, first, the upper end of the lock ring 2 pushes the inclined lower surface of the locking protrusion 14, and the inward direction makes the lower ends of the connecting pieces 9, 9 approach each other. Component force works. After that, when the top of the locking ridge 14 is fitted inside the lock ring 2 and finally the top of the locking ridge 14 protrudes from the lower end of the lock ring 2, the lower ends of the connecting pieces 9 and 9 that are approaching each other. Are separated again by the elastic force, and the lower end of the lock ring 2 is locked to the upper surfaces of the locking protrusions 14 and 14. The lock ring 2 cannot be detached from the connecting portion 6 unless an inward external force is applied to the lower ends of the connecting pieces 9 and 9 again. On the other hand, the upper end of the lock ring 2 is engaged with the lower surface of the restricting protrusion 18. Therefore, the lock ring 2 does not move up and down between the locking protrusion 14 and the restricting protrusion 18, and the inner peripheral surface of the lock ring 2 is in contact with the lock outer peripheral surface 15 and the rib 17 and fits in the connecting portion 6 without wobbling. In the locked state (see FIG. 4). In this locked state, the lock ring 2 can freely rotate.
[0017]
In addition, insertion recesses 20 and 20 are provided at two symmetrical positions in the radial direction of the inner surface of the upper end portion of the lock ring 2. The circumferential width of the insertion recess 20 and the circumferential width of the restriction projection 18, the depth of the recess of the insertion recess 20, the protrusion height from the outer surface of the upper end portion 11 of the restriction projection 18, and the insertion depression Since the vertical height of the place 20 is substantially equal to the vertical height of the restriction projection 18, the restriction protrusion 18 is accommodated in the insertion recess 20.
[0018]
Accordingly, the lock ring 2 can be lifted above the lower surface of the restricting projection 18 only when the lock recess 2 is rotated and the insertion recesses 20 and 20 are in a rotational phase relationship that matches the restricting projections 18 and 18 (see FIG. 3), and at this time, the lock ring 2 stops at the position due to the friction between the insertion recess 20 and the restriction projection 18, and the lock ring 2 is prevented from rotating by the engagement between the insertion recess 20 and the restriction projection 18. It becomes.
[0019]
