Abstract

The present invention relates to a flexible filler fitting jig. The flexible filler fitting jig comprises: a plate spring having a constant width and length and having a coiling elastic restoring force applied in one direction when unfolded or unfolded; and a handle provided at one end of the plate spring and capable of being grasped by an operator; wherein the plate spring has a longitudinal cross-section perpendicular to its longitudinal direction forming a curved surface that is curved upward, and when an external force is applied to the curved surface, it is coiled in an annular shape by the elastic restoring force to wrap around the fitting part.

Description

Flexible Pillar Fitting Jig The present invention relates to a fitting jig, and more specifically, to a flexible filler fitting jig that can be freely bent or unfolded and used in various work environments. As is well known, in semiconductor manufacturing processes, chemicals such as ultrapure water (DIW), sulfuric acid, phosphoric acid, hydrochloric acid, nitric acid, and hydrofluoric acid (hereinafter simply referred to as "chemical solutions") are used as cleaning agents, etching agents, and developing agents. These chemical solutions are supplied through a pipeline consisting of multiple connected pipes, and the pipes for supplying the chemicals are interconnected by fitting members. Tools such as wrenches (hereinafter referred to as fitting jigs) are used to connect the pipes and the fitting members. When using a wrench according to the conventional technology, a width adjustment wheel must be turned by hand to adjust the width of the jaw whenever the diameter of the pipe or fitting member to be connected changes. When using a wrench that adjusts the width of the jaw by turning a wheel in this way, there is a problem that a lot of force and time are consumed in the process of turning the wheel to match the width of the jaw with the diameter of the pipe or fitting member and comparing the width of the jaw with the diameter of the pipe or fitting member. In addition, conventional wrenches are difficult to use in crowded or confined spaces. FIG. 1 is a perspective view showing a flexible filler fitting jig according to an embodiment of the present invention. Figure 2 is a front view of the flexible filler fitting jig shown in Figure 1. Figure 3 is a drawing showing the state in which the deformed grip portion of the flexible filler fitting jig illustrated in Figure 1 is wound. Figures 4 and 5 are drawings showing the state in which the deformed grip portion of the flexible filler fitting jig is wrapped around the pipe fitting portion. Embodiments of the present invention are described below with reference to the attached drawings so that those skilled in the art can easily implement them. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein. Furthermore, in describing preferred embodiments of the present invention in detail, specific descriptions of related known functions or configurations are omitted if it is determined that such detailed descriptions may unnecessarily obscure the essence of the present invention. Additionally, the same reference numerals are used throughout the drawings for parts having similar functions and operations. The term 'comprising' a component means that, unless specifically stated otherwise, it does not exclude other components but rather allows for the inclusion of additional components. Specifically, terms such as "comprising" or "having" are intended to indicate the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof. Singular expressions include plural expressions unless the context clearly indicates otherwise. Additionally, the shapes and sizes of elements in drawings may be exaggerated for clearer explanation. Terms such as "first," "second," etc., may be used to describe various components, but said components should not be limited by said terms. These terms may be used for the purpose of distinguishing one component from another. For example, without departing from the scope of the present invention, the first component may be named the second component, and similarly, the second component may be named the first component. When it is stated that one component is "connected" or "connected" to another component, it should be understood that while it may be directly connected or connected to that other component, there may also be other components in between. Conversely, when it is stated that one component is "directly connected" or "directly connected" to another component, it should be understood that there are no other components in between. Other expressions describing the relationships between components, such as "between" and "exactly between," or "adjacent to" and "directly adjacent to," should be interpreted in the same way. Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by those skilled in the art to which the present invention pertains. Terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an ideal or overly formal sense unless explicitly defined in this application.
