Abstract

To the present invention relates to a quick nut which allows for quick detachment by one step operation, for example, for installing a low tank or a seat on a toilet stool by means of a bolt. Each nut piece 60 comprises a locking part 63 and a release part 64. The locking part 63, when a case 70 is made to slide toward the direction coming close to a base end part of a bolt 30, rotates around a rotating axis 62 with the external surface of the locking part 63 being pressed on the inner peripheral surface of the case 70, allows a female screw part 61 to protrude in a bolt hole 51, and engages the female screw part 61 with a male screw part 31 of the bolt 30 inserted into the bolt hole 51. The release part 64, when the case 70 is made to slide toward the direction away from the base end part of the bolt 30, rotates reversely around the rotating axis 62 with the external surface thereof being pressed on the inner peripheral surface of the case 70, separates the female screw part 61 from the male screw part 31 of the bolt 30.

Description

A7 V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to quick-installation screw Φ M ^ ^ ^ 〇 For example, when using a low-profile water tank or a toilet seat with a screw-check women's wear in a toilet bowl Quick nuts, especially those that can be removed with a simple operation. Eight [Knowledgeable technology] It is stated as =: Yes, the month described in Japanese Patent Application Laid-Open No. 9/119424 is a well-known quick-install nut. In the above publication, there is described a quick-install nut including: a base, a bolt hole through which a bolt is inserted; at least one pair of nut pieces, which are continuous with the base described above through a hinge portion, and have a female thread portion It is screwed with the male thread part inserted in the inspection of the bolt hole; the metal elastic spring material pushes the female thread part of the nut piece from the male thread part toward the spaced direction, and the box is embedded in the base The outer periphery 'causes the female screw portion of each nut piece to approach the male screw portion against the elastic spring material so as to slide toward the axial direction of the bolt hole, and is screwed with the male screw portion. As shown in Figures 4 and 6 of the aforementioned publication, the base is provided with a lock. In the description box ', it is provided with an L-shaped cam groove in which a pin slides. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs The aforementioned cam groove is composed of a second cam groove extending toward the sliding direction of the box, and a second cam groove extending toward the circumferential direction of the box. When the box is slid, the pins of the base are relatively moved along the i-th cam groove. When the female screw portion is engaged in the locked position of the male screw portion, and each member is rotated, as shown in Fig. 6 of the aforementioned publication, the pin of the base moves relatively along the second cam groove. As a result, the box is prevented from sliding against the base. [Problems to be Solved by the Invention]

In contrast, as shown in FIGS. 6 to 9, a projection 65 ′ is provided on the outer surface of each of the nut pieces 60 to be slidably connected to the pressing portion 72 of the case 70. In this embodiment, the protrusions 65 extend along the sliding direction of the box 70 and are formed in a plurality of lines. As shown in FIG. 8, each protrusion 65 protrudes in a mountain shape. On the other hand, as shown in FIGS. 10 and 11, a pair of recesses 73 is provided on the inner peripheral surface of the through-hole 71, and the pair of recesses 73 is 90 degrees out of phase with the pair of crimping portions 72. 'For a pair of convex portions 53 of the base 50 to be slidably fitted. A pair of convex portions 53 of the base 50 are slidably fitted in the pair of grooves to prevent the base 50 in the through hole 71 of the box 70 from rotating. On the other hand, as shown in FIG. 16, between the base 50 and the box 70, a stopper 74 'is provided to limit the sliding range of the base 50 in the box 70. Specifically, as shown in FIG. 10, FIG. 11 and FIG. 16, the stoppers 74 project from the bottoms of the pair of grooves 73 of the box 70 toward the inside of the through holes 71, respectively. As shown in Fig. 16, each of the stoppers 74 projects in a shape of a right-angled triangular cross-section with the inclined surface facing upward. As shown in Figs. 14 and 16, each stopper 74 is slidably inserted into each of the sliding grooves 54 of the base 50 in a slidable manner.

Here, if the base is pushed in forcefully, since the base 50 and the box 70 are slightly bent, each stopper M is respectively inserted into each of the sliding grooves 54. Embedded. Each of the stoppers 74 is configured to slide in a relatively up and down direction along each slide 胄 54 to limit the sliding range of the base 50 in the box 70. That is, 'Although not shown, the stoppers 74 of each box 70 prevent the base μ from coming out from the through-hole 71 of the box 70 so as to abut the bottom of each slide 胄 54 of the base S50. . θ (How to use) The following describes how to use the quick-fit nut 10 with the above structure. As shown in FIG. 1, 'the bolt 30 inserted through the low-water tank 20 is passed through the toilet bowl 40' at the tip of the bolt 30 And align with the base screw inspection hole η from the bottom. As shown in Fig. 1 ', each of the left and right nut pieces 60 is locked and opened to each other in a flowering state. η to move. Then, as shown in Fig. 15 and Fig. 16, slide the box 70 upwards. As shown in Figs. 15 and 16, when the box 70 slides upward, the left and right dust-receiving portions 72 slide to the left and right. Each protrusion of the nut piece 60. Here, as shown in FIG. 15, if the box 70 is pushed up j by force, the locking portions M of the left and right nut pieces 60 are added by the left and right dust adding portions 72. : Turn the left and right locking parts 63 toward each other and rotate on each axis M.
