FAST-POSITIONING PIN FOR STORAGE CASE
A storage case includes a positioning pin, a plurality of O-rings, and a case body. The positioning pin has an outer circumference having opposite end portions forming recessed circumferential grooves for receiving therein the O-rings for realizing tight engagement. The O-rings have outer circumferences projecting beyond the outer circumference of the pin for passive compressed elastic deformation. As such, the positioning pin is insertable through positioning holes defined in opposite side walls of an end-open case body in such a way that the O-rings are located inside or outside the positioning holes for retention and thus fast, repeatable, and resilient insertion and removal of the storage case can be realized.
The present invention generally relates to a fast-positioning pin, which provides a breakthrough of structural arrangement of a conventional storage case by providing a positioning pin extending through positioning bores defined in opposite sidewalls of an open-end case body to realize a positioning operation through fast and resilient insertion and removal.
(b) DESCRIPTION OF THE PRIOR ARTA conventional storage box is often of a structural arrangement comprising an outer enclosure and an inner or alternatively an outer enclosure that is divided in a height dimension into several layers to respectively receive inner cases therein by which articles can be received and stored in the cases and the enclosure. However, such a storage box is disadvantageous in that the inner case (or drawer) is not provided with any positioning or retention structure so that when the box is moved, the inner case may get easily separated from the outer enclosure, leading to loss and damage of the articles or objected contained in the inner case. This is impractical and requires an improvement. The present invention thus aims to provide a solution to such a problem.
SUMMARY OF THE INVENTIONThe primary objective of the present invention is to provide a fast positioning pin for a storage case, and particularly, the storage case is composed of a positioning pin, a plurality of O-rings, and a case body that are arranged in such a way that the storage case can be retained in position through fast and resilient insertion and/or removal of the pin.
Another objective of the present invention is to provide a fast positioning pin of a storage case, wherein the pin has an outer circumference having opposite end portions, which form recessed circumferential grooves for receiving O-rings to respectively fit therein.
A further objective of the present invention is to provide a fast positioning pin of a storage case, wherein the O-rings have an outer circumference projecting beyond the outer circumference of the positioning pin to thereby form a passive and compressed elastic deformation.
Yet a further objective of the present invention is to provide a fast positioning pin of a storage case, wherein the O-rings are fit to the positioning pin outside or inside side walls of the storage case to provide a positioning and retaining function similar to raised rims.
The foregoing objectives and summary provide only a brief introduction to the present invention.

Claims
1. A storage case comprising a positioning pin, a plurality of O-rings, and a case body, wherein the positioning pin comprises a cylindrical bar like body having an outer circumference having opposite end portions forming a plurality of semi-circularly recessed circumferential grooves, wherein the plurality of O-rings is each made of a resilient rubber material in the form of a ring like body for fitting in a corresponding one of the recessed circumferential grooves, and wherein the case body comprises an end-open hollow body having opposite sidewalls on opposite sides of the open end that define opposing positioning holes for receiving the positioning pin to extend therethrough, the positioning holes having a diameter that is slightly greater than an outside diameter of the positioning pin, wherein outer circumferences of the O-rings project beyond an outer circumference of the positioning pin for passive compressed elastic deformation for passing through the positioning holes and also for resuming original shapes after passing through the positioning holes whereby the outer circumferences of the O-rings are retained between the positioning holes on the opposite sides of the case body to have the positioning pin held in position without undesired separation and realize fast, repeatable, and resilient insertion and removal of the storage case.
2. The storage case according to claim 1, wherein the semi-circularly recessed circumferential grooves formed in the outer circumference of the positioning pin are located outside the positioning holes on the opposite sides of the storage case for receiving the O-rings to fit therein.
