Description

[Technical field]

[0001] The present invention relates to an operating tool used for opening and closing a movable lid of a lidded box body such as a box-shaped indoor high pressure cutout. [Background technology]

[0002] Operating tools for opening and closing a movable lid (cover) of a high-pressure cutout have been developed (for example, Patent Document 1).

[0003] The operating tool disclosed in Patent Document 1 has a rod member that can be inserted into a through hole formed in the cover of a box-shaped high-voltage cutout, and after this rod member is inserted into the insertion hole of the cover, the cover of the high-voltage cutout can be opened by pulling the operating tool attached to the tip of an insulated operating rod.

[0004] [Patent Document 1] JP 2020-123558 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, with the operating tool disclosed in Patent Document 1, as mentioned above, although the movable lid (cover) of the high-pressure cutout can be opened and closed, there was a problem in that the movable lid could not be removed from the main body case of the high-pressure cutout.

[0006] The present invention has been made in consideration of such problems, and its object is to provide an operating tool that can not only open and close a movable lid of a lidded box body such as a high-pressure cutout, but also remove or attach the movable lid to the main case of the lidded box body. [Means for solving the problem]

[0007] According to one aspect of the present invention, A main body portion, A hook portion protruding from the main body portion; and a support fitting portion protruding from the main body portion, a cross-sectional longitudinal width of the hook portion is shorter than a minimum width of an insertion hole formed in a movable lid of a lid-equipped box body, The cross-sectional longitudinal width of the support metal fitting portion is longer than the minimum width of the insertion hole and shorter than the maximum width of the insertion hole. An operating tool is provided.

[0008] Preferably, The hook portion and the supporting metal fitting portion are provided so as to protrude in the same direction.

[0009] Preferably, The hook portion is provided so as to protrude continuously from the tip of the supporting metal fitting portion.

[0010] Preferably, The support metal fitting has a step formed thereon which engages with an edge of the insertion hole when the support metal fitting is inserted into the insertion hole. Effect of the Invention

[0011] According to the operating tool of the present invention, when opening and closing the movable lid of the lid-equipped box, the operation is performed with the hook part inserted into the insertion hole of the movable lid. Since the cross-sectional longitudinal width of the hook part is set to be shorter than the minimum width of the insertion hole, the hook part can rotate freely within the insertion hole, and the movable lid can be opened and closed smoothly.

[0012] Furthermore, when the movable lid is to be removed from or attached to the main case of the lidded box, the operation is performed with the support metal part inserted into the insertion hole of the movable lid. The cross-sectional longitudinal width of the support metal part is set to be longer than the minimum width of the insertion hole and shorter than the maximum width of the insertion hole, so that when the insulating operating rod is tilted, the support metal part rotates within the insertion hole and the outer edge of the support metal part abuts against the inner surface of the insertion hole, resulting in a "locked state."

[0013] In this locked state, the movable lid also rotates in accordance with the rotation of the support metal fitting, so that the movable lid can be removed from or attached to the main case of the lidded box body.

[0014] This makes it possible to provide an operating tool that can not only open and close the movable lid of the lidded box body, but also remove and attach the movable lid to and from the main case of the lidded box body. [Brief description of the drawings]

[0016] (Configuration of the operating tool 100) An operation tool 100 according to an embodiment to which the present invention is applied will be described. Fig. 1 is a front view of the operation tool 100, and Fig. 2 is a left side view of the operation tool 100. Furthermore, Fig. 3 is an exploded perspective view of the operation tool 100.

[0017] 4 shows a high-pressure cutout A that is handled using the operating tool 100. This high-pressure cutout A is roughly composed of a main body case B and a movable lid C, and the movable lid C is formed with an insertion hole D through which the operating tool 100 is inserted. The movable lid C is rotatable relative to the main body case B by engaging a tip of a hinge F formed on the movable lid C with a hinge engagement rod E in the main body case B. In this embodiment, the high-pressure cutout A is described as an example, but the cutout that is handled using the operating tool 100 is not limited to the high-pressure cutout A, and may be another box with a lid.

[0018] The operating tool 100 according to this embodiment is generally composed of a main body portion 110, a support metal fitting portion 112, and a hook portion 114.

[0019] The main body 110 has a cylindrical lower body 120 into which the tip of the insulating operating rod X is inserted, and an upper body 122 extending from the top surface of the lower body 120 in the longitudinal direction of the main body 110. The material of the main body 110 is not particularly limited as long as it has the required strength, and possible materials for the main body 110 include, for example, aluminum, stainless steel, FRP, nylon, polyacetal, etc., but it is preferable to use aluminum for the main body 110 in consideration of operability and strength.

[0020] An operating rod insertion hole 124 into which the tip of the insulating operating rod X is inserted is formed on the bottom surface of the lower body part 120. In addition, a hook-shaped engaging pin fitting groove 126 into which an engaging pin (not shown) of the insulating operating rod X is fitted is formed on the side peripheral surface of the lower body part 120.

[0021] The upper body 122 has cut planes 128 formed on both sides, as if a part of the round bar had been cut away by a plane parallel to the longitudinal direction of the round bar. Furthermore, the upper body 122 has two drilled holes 130 (see FIG. 3) formed in a direction perpendicular to the cut planes.

[0022] The support metal part 112 has a support metal part main body 132, a hook part insertion hole 134, a hook part fixing pin hole 136, a bolt screwing hole 138 (see FIG. 3), and a step part 140.

[0023] The support metal fitting main body 132 is a part that protrudes from the main body 110, and in this embodiment, is formed in a substantially rectangular parallelepiped shape with rounded corners. The material of the support metal fitting 112 is not particularly limited as long as it has the required strength, and possible materials include aluminum, stainless steel, FRP, etc., but since the lighter the weight of the support metal fitting 112, the better in terms of operability, it is preferable to use aluminum.

[0024] The cross-sectional longitudinal width Y of the support bracket main body 132 is set to be longer than the minimum width HS of the insertion hole D formed in the movable cover C of the high-pressure cutout A, and shorter than the maximum width HB of the insertion hole D (see FIG. 4). The thickness of the support bracket main body 132 (the width in the direction perpendicular to the cross-sectional longitudinal width Y) is set to be shorter than the minimum width HS of the insertion hole D.

[0025] The hook portion insertion hole 134 is a round hole into which the hook portion 114 is inserted, and in this embodiment, is formed slightly toward the end (near the tip of the main body 110) on the tip surface of the support bracket main body 132. By forming the hook portion insertion hole 134 slightly toward the end (near the tip of the main body 110) on the tip surface of the support bracket main body 132 in this manner, when the hook portion 114 is inserted into the insertion hole D of the movable lid C in the high pressure cutout A, as will be described later, the support bracket main body 132 is less likely to come into contact with and interfere with the movable lid C.

[0026] The hook portion fixing pin hole 136 is formed on the side surface of the support bracket main body 132, and is a circular hole communicating with the hook portion insertion hole 134. A hook portion fixing pin 141 is inserted into this hook portion fixing pin hole 136, and the tip of the hook portion fixing pin 141 is inserted into a hook portion fixing pin insertion hole 144 (described later) formed in the hook portion 114, thereby preventing the hook portion 114 from undesirably coming out of the hook portion insertion hole 134.

[0027] The bolt screwing hole 138 is a screw hole formed in the surface (rear end surface) of the support fitting main body 132 opposite to the surface on which the hook portion insertion hole 134 is formed and in contact with the cutting plane 128 of the main body upper portion 122. In this embodiment, two bolt screwing holes 138 are formed side by side along the longitudinal direction of the main body 110.

[0028] The step portion 140 is formed on an edge of the support bracket main body 132 near the tip of the main body 110. As described below, this step portion 140 is adapted to engage with the periphery of an insertion hole D formed in a movable cover C of the high pressure cutout A when the support bracket 112 is inserted through the insertion hole D. It is preferable that the groove width W from the base of the support bracket main body 132 (the abutment position with the main body upper part 122 of the main body 110) to the step portion 140 in the support bracket main body 132 be set to be longer than the depth dimension G (see FIG. 5) of the insertion hole D in the movable cover C of the high pressure cutout A.

[0029] Hook portion 114 is a portion that protrudes from main body portion 110, and has a hook portion main body 142 that is substantially rod-shaped, and a hook portion fixing pin insertion hole 144 formed at the base side (the side that is inserted into support metal fitting portion 112) end of hook portion main body 142. The material of hook portion 114 is not particularly limited as long as it has the required strength, and possible materials include aluminum, stainless steel, iron, etc., but since hook portion 114 is required to have strength and corrosion resistance, it is preferable to use stainless steel.

[0030] The cross-sectional longitudinal width Z of the hook body 142 is set to be shorter than the minimum width HS (see FIG. 4) of the insertion hole D formed in the movable cover C of the high-pressure cutout A.

[0031] In this way, in the operating tool 100 of this embodiment, the hook portion 114 and the support bracket portion 112 protrude from the main body portion 110 in the same direction, and the hook portion 114 protrudes continuously from the tip of the support bracket portion 112 to the support bracket portion 112.

[0032] (Assembly procedure of the operating tool 100) A procedure for assembling the operating tool 100 according to this embodiment will be briefly described below. First, the hook body 142 is inserted into the hook insertion hole 134 formed in the support bracket body 132 of the support bracket 112, and the hook fixing pin 141 is inserted into the hook fixing pin hole 136 of the support bracket body 132 and the hook fixing pin insertion hole 144 of the hook body 142, thereby fixing the support bracket 112 and the hook 114 to each other.

[0033] Thereafter, the two bolts 146 are inserted into the drilled holes 130 formed in the upper body portion 122 of the body portion 110, and the tips of the bolts 146 are screwed into the bolt screwing holes 138 formed in the support metal fitting body 132 to fix the support metal fitting 112 and the body portion 110 together. This completes the assembly of the operating tool 100.

[0034] Of course, the supporting metal fitting portion 112 and the main body portion 110 may be fixed to each other first, and then the supporting metal fitting portion 112 and the hook portion 114 may be fixed to each other.

[0035] (Procedure for using the operating tool 100) Next, a procedure for opening and closing the movable cover of the high voltage cutout using the operating tool 100 according to this embodiment, and for removing and attaching the movable cover to and from the main body case of the high voltage cutout will be described.

[0036] As shown in FIG. 5, when the movable cover C is closed on the main body case B, the hook portion 114 of the operating tool 100 is inserted into the insertion hole D of the movable cover C of the high voltage cutout A.

[0037] From this state, by pulling the insulating operating rod X toward you to move the operating tool 100 toward you, the movable cover C rotates around the hinge engagement rod E of the main case B as shown in FIG. 6, and the movable cover C becomes open as shown in FIG. 7.

[0038] As described above, the cross-sectional longitudinal width Z of the hook portion main body 142 is set to be shorter than the minimum width HS of the insertion hole D, so that the hook portion main body 142 can rotate (pivot) relatively within the insertion hole D until the movable cover C, which is in the closed state, is opened, thereby allowing the movable cover C to be smoothly opened.

[0039] 7, the hook portion 114 is further pushed into the insertion hole D, and the support metal part 112 fits into the insertion hole D. As described above, the cross-sectional longitudinal width Y of the support metal part main body 132 is set to be shorter than the maximum width HB of the insertion hole D, so that the support metal part 112 can be fitted into the insertion hole D in this manner.

[0040] After fitting the support metal fitting 112 into the insertion hole D in this manner, the insulating operating rod X is operated to tilt the operating tool 100 further toward the user from the state shown in Fig. 7. Then, as described above, the cross-sectional longitudinal width Y of the support metal fitting main body 132 is set to be longer than the minimum width HS of the insertion hole D, so that as the support metal fitting main body 132 is tilted relative to the insertion hole D, the outer edge of the support metal fitting main body 132 comes into contact with the inner surface of the insertion hole D, resulting in a "locked state" in which further rotation is not possible. In this locked state, the movable cover C also rotates in accordance with the rotation of the support metal fitting 112.

[0041] As a result, by operating the insulated operating rod X and the operating tool 100 to pull the movable cover C upward in the figure (or diagonally forward and to the left), the hinge F of the movable cover C can be disengaged from the hinge engagement rod E of the main case B, and the movable cover C can be removed from the main case B.

[0042] When the removed movable cover C is attached to the main case B and then closed, the above-mentioned steps are carried out in reverse.

[0043] This makes it possible to provide an operating tool 100 that can not only open and close the movable cover C of the high voltage cutout A, but also remove and attach the movable cover C to and from the main body case B of the high voltage cutout A.

[0044] Furthermore, since the hook portion 114 and the support bracket portion 112 protrude from the main body portion 110 in the same direction, when the movable lid C is rotated, the hook portion 114 is inserted into the insertion hole D, and when the movable lid C is removed from the main body case B, the operating tool 100 can be moved in the same direction to insert the support bracket portion main body 132 into the insertion hole D.

[0045] Furthermore, since the hook portion 114 protrudes continuously from the tip of the support bracket portion 112 to the support bracket portion 112, when the movable lid C is rotated, the hook portion 114 is inserted into the insertion hole D, and when the movable lid C is removed from the main body case B, the support bracket portion main body 132 can be inserted into the insertion hole D by a simple operation of further pushing the operating tool 100 into the insertion hole D.

[0046] Furthermore, the support bracket 112 according to this embodiment is formed with a step 140 that engages with the periphery of the insertion hole D when the support bracket 112 is inserted through the insertion hole D, and the groove width W from the base of the support bracket main body 132 (the position where the main body 110 abuts against the main body upper part 122) to the step 140 is set to be longer than the depth dimension G of the insertion hole D in the movable cover C of the high pressure cutout A. As a result, when the outer edge of the support bracket main body 132 abuts against the inner surface of the insertion hole D and enters a "locked state" in which it cannot be rotated any further, the step 140 engages with the edge of the insertion hole D, thereby preventing the support bracket 112 from undesirably slipping out of the insertion hole D.

[0047] (Variation 1) In the operating tool 100 according to the embodiment described above, the main body portion 110, the support bracket portion 112, and the hook portion 114 are configured as separate components, but the operating tool 100 may also be configured by forming each of these portions integrally.

[0048] (Variation 2) In addition, in the operating tool 100 according to the embodiment described above, the support metal fitting 112 is formed of one member, but instead of this, for example, two round bar-shaped members of different lengths may be provided protruding in parallel from the main body 110 as shown in Fig. 8. In this case, the tip of the longer bar 150 becomes the hook portion 114, and the base portion of the longer bar 150 and the shorter bar 152 are combined to form the support metal fitting 112, and the hook portion 114 and the support metal fitting 112 protrude from the main body 110 in the same direction, and the hook portion 114 protrudes continuously from the tip of the support metal fitting 112 to the support metal fitting 112.

[0049] Of course, in this case too, the cross-sectional longitudinal width Y of the support fitting portion main body 132 (the distance between the outer end of the base portion of the longer bar 150 and the outer end of the shorter bar 152) is set to be longer than the minimum width HS of the insertion hole D formed in the movable cover C of the high-pressure cutout A, and shorter than the maximum width HB of the insertion hole D. In addition, the cross-sectional longitudinal width Z of the hook portion main body 142 (the diameter dimension of the tip portion of the longer bar 150) is set to be shorter than the minimum width HS of the insertion hole D formed in the movable cover C of the high-pressure cutout A.

[0050] (Variation 3) In addition, in the operating tool 100 according to the embodiment described above, the hook portion 114 protrudes continuously from the tip of the support bracket portion 112 to the support bracket portion 112. Alternatively, as shown in FIG. 9, the hook portion 114 and the support bracket portion 112 may protrude from the main body portion 110 in the same direction and parallel to each other.

[0051] The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. The scope of the present invention is defined by the claims, not the above description, and is intended to include all modifications within the meaning and scope of the claims.
