[Structure] A ground plate having a metal plate of a predetermined width that comes into contact with the bottom surface of a metal member such as a mechanical device or a packaging container is exposed and embedded from a floor surface such as the ground, and a tip portion bulges and curves toward the upper surface side. It is configured to be detachably connected to the end of the metal plate and urged so that the bulging curved surface comes into contact with the bottom surface of the metal member.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a grounding member for mounting a metal container such as a packaging container such as a drum can or a mechanical device on the floor. In particular, the present invention relates to a grounding member capable of maintaining the flatness of a metal member to be placed and reliably grounding from the bottom surface.

[0002]

[Prior art]

 Equipment that uses volatile solvents, and packaging containers such as drums that are filled with paint that easily ignites due to a discharge phenomenon are generally placed on the metal parts of these equipment and packaging containers. The danger of explosion due to the electric discharge phenomenon is eliminated by connecting the ground plate buried in the surface. Various methods are conceivable for disposing the metal plate such as the ground plate. For example, in the case of a drum can packaging container, two metal plates are parallel to each other as shown in FIG. The drum cans are regularly placed on the metal plate, and the drum cans are arranged so as to surely contact both of the annular members around the bottom of the drum can. The flatness of the drum can was maintained by these two metal plates, and the outer peripheral edge of the bottom of the drum can was placed in contact with the two metal plates.

[0003]

[Problems to be solved by the device]

 In this case, if the ground or floor is flat, there is no problem, but if the floor such as the ground is uneven as shown in Fig. 4 or if there are obstructive stones such as obstacles, a drum can There was a state where one side of the bottom surface of the packaging container or the mechanical device floated up, or the entire bottom surface floated up and did not completely contact the two metal plates. When two metal plates are buried at regular intervals, the size of the bottom surface of the packaging container is not constant and there are various sizes.Therefore, a packaging container with a diameter smaller than the space between the two metal plates is used. In the case of, only one metal plate was touched, and there was a case where it was inclined to the bottom side where it did not touch. The present invention solves the above-mentioned problems and provides a grounding member capable of reliably grounding from the bottom surface of a metal member such as a packaging container. An object of the present invention is to provide a grounding member having a grounding plate that surely contacts the bottom surface regardless of the size of the packaging container.

[0004]

[Means for Solving the Problems]

 The purpose of this invention is to expose the upper surface of a metal plate of a predetermined width that comes into contact with the bottom surface of a metal member such as a mechanical device or a packaging container from the floor surface and embed it, and to ground the ground plate whose tip portion bulges and curves upward. This has been achieved by a grounding member, which is detachably connected to the end of a metal plate and is biased so that the bulging curved surface contacts the bottom surface of the metal member. In particular, the surface is exposed and one metal plate is embedded in the floor surface such as the ground, and the earth plate extending along this floor surface is attached to and detached from the end of the metal plate with fixing pins such as screws. The above-mentioned object can be easily achieved by a structure in which the other end side of this ground plate is bulged and curved toward the bottom side of the mechanical device or the packaging container and the metal plate and the ground plate are linearly connected.

[0005]

[Action]

 The grounding member of this invention is embedded in the floor surface, the grounding plate is detachably attached to the tip of the metal plate buried so that the surface is exposed, and the curved projection is provided at the end of this grounding plate. The bottom surface of a metal packaging container such as a mechanical device or a drum that is placed on the metal plate of the book surely contacts the convex portion of the end of the earth plate. Moreover, since the earth plate connected to the buried metal plate is detachably attached with a fixing pin or the like and is connected to the metal plate, it is possible to easily replace earth plates of various sizes and shapes. Even if the size of the machinery and packaging in which it is placed is changed, it is possible to reliably ground it.

【Example】

 FIG. 1 is a side view of the grounding member of the present invention embedded in a floor surface, and FIG. 2 is a usage state diagram of the grounding member of the present invention. FIG. 3 is an explanatory view showing various mounting states in the plan view of FIG. FIG. 4 is a diagram showing a storage state of a conventional packaging container. FIG. 5 is a diagram showing a state in which a large number of the packaging containers of FIG. 4 are arranged and mounted on two metal plates. An embodiment shown in the drawings of the present invention will be described. 1 is a metal packaging container such as a mechanical device or a drum which is a metal member that needs to be grounded. A fixing piece 3 having a screw hole is integrally formed at one end of the metal plate 2 embedded in the floor surface such as the ground so that one surface is exposed at a position in contact with the bottom surface side of the packaging container 1. ing. A bolt 5 for fixing a thin ground plate 4 is screwed into a screw hole of a fixing piece 3 provided at the end of the metal plate 2. The metal plate 2 and the ground plate 4 are electrically connected by the bolt 5. The straight portion of the ground plate 4 contacts the surface of the floor such as the ground, and expands upward inside the recess 7 at the tip thereof, that is, between the straight portion extending from the fixing piece 3 and the recess 7. The projecting part 6 is formed.

In the grounding member of the present invention, one metal plate 2 having a predetermined width is embedded in the floor surface such as the ground, and the surface is exposed. The fixed piece 3 at the tip of the embedded metal plate 2 is used. The ground plate 4 laid on the floor is fixed to the ground plate 4 with bolts 5 with the bulging portion 6 provided at the tip end facing upward. On the one metal plate 2 fixed in this manner, the drum can which is the packaging container 1 is placed so that a part of the bottom surface of the drum can contacts the metal plate 2. Since the ground plate 4 is fixed to the extended portion of the metal plate 2, the center portion or the other end of the bottom surface of the packaging container 1 comes into contact with the bulging portion 6 of the ground plate 4. At this time, the bulging portion 6 is crushed by the weight of the packaging container 1 and the concave portion 7 slides on the floor surface. Therefore, the packaging container 1 necessary for grounding surely contacts the ground plate 4 by the elastic force of the bulging portion 6.

Further, since the grounding member of the present invention is formed of the single metal plate 2, as shown in FIG. 3, the grounding plate is surely held even when the packaging container 1 indicated by the chain double-dashed line is placed. 4 can be brought into contact with the bottom surface of the packaging container. Further, since the earth plate 4 connected to the metal plate 2 buried in the ground is detachably attached, the earth plate 4 of various lengths can be extended. Therefore, it is possible to use the grounding material according to the size of the mechanical device or the packaging container.

[0009]

[Effect of device]

 The grounding member of the present invention is one in which a metal plate is placed on the floor so that the ground can be surely grounded from the bottom according to the size of the machinery and packaging to be placed. Moreover, since a detachable ground plate is attached to the tip, it can be easily replaced even if this ground plate is damaged, and the protruding part that is bulged upward and biased is provided on the bottom surface. It is possible to make sure contact. According to this invention, the ground member can be provided at a low cost.
