Description

  The present invention restricts the rotation of the lid body in an equipment housing box comprising a box body having an equipment housing space formed by a bottom wall portion and a side wall portion, and a lid body that closes an opening of the box body. It is related with the apparatus which performs.

  For example, when a power supply cable is drawn into a house or a power cable is provided at a construction site or the like, a wiring pole P for drawing an overhead electric wire is erected on the site, and the wiring pole P is connected to the wiring pole P. Is equipped with a storage box for storing devices such as earth leakage breakers, branch breakers, and power meters. In addition, since many information electrical devices and outlets are introduced when the Internet environment and the network environment are prepared, a storage box for concentrating and arranging them is attached to an indoor wall surface. As shown in FIG. 13, the wiring pole P is generally erected on the ground surface by embedding the lower end portion of the cylindrical column 1 in the ground, and the upper end portion is DV. A drawing band 3 for drawing the wire 2 is attached. In FIG. 13, reference numeral 4 is a DV insulator for insulating the column body 1 from the DV line 2, and reference numeral 5 is a pole cap for covering the upper end portion of the column body 1.

  As a conventional storage box, for example, Patent Document 1 discloses a storage box that fixes devices to the inner surface of the bottom wall portion of the storage box. In the storage box, since the devices are directly fixed to the inner surface of the bottom wall portion, a large device storage space can be ensured in that an extra fixing member or the like is not required. However, since the fixing surface for fixing the devices is only one surface of the bottom wall portion, the internal space of the storage box cannot be utilized to the maximum extent as the device storage space. In particular, in the case of a device whose height dimension is too large, if the device is fixed to the bottom wall portion, it interferes with the lid.

  The device storage box device having the above configuration includes a box body having a device storage space formed by a bottom wall portion and a side wall portion, and a lid body that closes an opening of the box body. Since it is freely rotated by the connecting tool, it can be easily opened and closed by wind or contact unless the lid is locked. For this reason, for example, when performing various operations in or around the box body with the lid open, even if it is desired to maintain the state in which the lid remains open for the sake of work efficiency, the lid can be easily Since the body is blocked, the lid obstructs the work and the work efficiency is lowered.

JP 2004-69632 A

  An object of the present invention is to prevent a lid from being opened and closed by wind or contact when a work is performed in or around a box body of a device storage box device.

  The invention of claim 1 for solving the above-mentioned problem is a device storage box comprising a box body having a peripheral flange portion formed on the periphery of the opening and a lid body hinged to the box body. A substantially L-shaped closing prevention lever is attached to a portion of the back surface of the lid close to the hinge connecting portion side so as to be rotatable about a rotation axis substantially perpendicular to the lid. When the contact portion of the prevention lever is disposed substantially orthogonal to the rotation axis of the hinge connecting portion, the contact portion contacts the peripheral flange portion of the box body, and the rotation of the lid is restricted. At the same time, when the abutting portion is arranged substantially in parallel with the pivot axis, the abutment is released and the lid can be freely rotated.

  Since the rotation of the lid relative to the box body can be restricted or the restriction can be released only by the rotation of the closing prevention lever attached to the hinge connecting part side on the back surface of the lid, the inside of the box body When performing the connection work or the like, if it is desired to keep the lid open, the contact portion of the blocking prevention lever is disposed substantially orthogonal to the pivot axis of the hinge connecting portion, and If the abutting portion can abut on the peripheral flange portion of the box body, the opening angle of the lid body with respect to the opening surface of the box body can be prevented from becoming a certain angle or less.

  Further, when it is desired to close the opening of the box main body with a lid, the contact portion of the closing prevention lever is rotated until the contact portion of the closing prevention lever is substantially parallel to the rotation axis of the hinge connecting portion. And the peripheral flange portion of the box body do not interfere with each other, and the closing is possible.

  Since the closure prevention lever is unevenly distributed on the hinge connecting part side of the lid, when the lid is opened and various operations are performed in or around the box body, the closure prevention lever interferes with the work. When the lid is closed, the closure prevention lever as a whole is disposed opposite to the peripheral flange portion with a slight clearance from the peripheral flange portion of the box body. Since it is accommodated in the inside, interference with the equipment accommodated in the equipment accommodating space in the box body can be avoided.

  According to a second aspect of the present invention, in the first aspect of the invention, the box body and the lid are connected by a pair of butterfly plate connectors arranged at a predetermined interval. It is characterized by being arranged in the part of the butterfly plate connector.

  According to the invention of claim 2, since the closing prevention lever is arranged at one corner on the hinge connecting portion side with respect to the opening of the box body, it can be applied to the devices accommodated in the box body. The position with the least interference.

  According to a third aspect of the present invention, in the second aspect of the present invention, the contact portion of the blocking prevention lever is disposed substantially orthogonal to the rotational axis of the hinge connection portion, and the box of the pair of butterfly plate connectors is In the state of abutting against the butterfly plate connector on the main body side, the tip of the contact portion of the blocking prevention lever is a pair of fixing the butterfly plate connector on the box body side to the peripheral flange portion of the box body. It is characterized by being arranged between screws.

  According to the invention of claim 3, in the state where the blocking prevention lever is arranged at a position where blocking of the lid is prevented, the tip of the linear contact portion is connected to the butterfly plate connector on the box body side. Since the cover body is disposed between a pair of screws fixed to the peripheral flange portion of the box body, the lid body is in a range in which the lid body is larger than the regulated opening angle in a state where the closure of the lid body is regulated with respect to the box body. Even if the closing prevention lever tries to turn around the turning shaft portion, the tip of the contact portion is caught by the head of the screw, and thus the turning prevention lever is prevented from turning. For this reason, it is possible to reliably prevent the restriction from being released by the rotation of the closing prevention lever in a state where the box body is restricted so as not to be closed.

  According to the present invention, the rotation of the lid with respect to the box body can be restricted or the restriction can be released only by the rotation of the closing prevention lever attached to the hinge connecting portion side portion on the back surface of the lid. At the same time, since the blocking prevention lever is attached to a portion on the hinge connecting portion side on the back surface of the lid, there is little or no interference with devices housed in the box body.

  The equipment storage box B includes a box body H and a lid C that closes the opening 30 of the box body H. The device storage box device W includes the device storage box B and a device fixing plate L. First, the device storage box B constituting the device storage box device W will be described. As shown in FIG. 12, the equipment storage box B is attached to a wiring pole P temporarily installed outdoors to draw in a cable E for supplying power to a construction site or the like with a pole band 80 or the like. A box body H having a substantially rectangular parallelepiped shape in which K is accommodated, and a lid C for closing the opening 30 of the box body H are configured. As shown in FIG. 1 or FIG. 2, the lid C includes a hinge connecting portion 22 on one side of the side wall portion 20 constituting the box body H, and a hinge connecting portion 53 on the lid C side. The box body H is connected to the box body H so as to be openable and closable. Both the box body H and the lid body C are formed of a resin material. In the present embodiment, the device storage box B in the device storage box device W is arranged in a vertically long shape so that the butterfly plate connector Q is on the right side and the lid C is opened to the right in front view. The case where it is attached to the wiring pole P will be mainly described. However, it is also possible to mount the device storage box B in a horizontally long position and rotate and open the lid C so that the butterfly plate connector Q is on the upper side.

  The box body H will be described with reference to FIGS. The box main body H is composed of a substantially rectangular bottom wall portion 10 having rounded four corners and a side wall portion 20 standing upright from the entire periphery of the bottom wall portion 10, that is, a substantially rectangular shape having an opening 30. The box is raised so that the opening 30 is disposed on the front side. A space formed by the bottom wall portion 10 and the side wall portion 20 is a device accommodating space V. The opening 30 is formed inward from the outer periphery of the side wall 20 by a predetermined width on the front surface of the box main body H, and is an upright peripheral flange portion that stands perpendicular to the opening surface over the entire periphery of the opening 30. 31 is provided. When the lid C is closed, the upper end 31a of the upright peripheral flange 31 contacts the packing 55 fitted in a peripheral groove 54 (described later) formed on the back surface of the lid C. For this reason, the standing peripheral flange portion 31 has a function of closing a gap generated between the box body H and the lid body C and preventing rainwater and dust from entering the box body H. Yes.

The configuration of the bottom wall portion 10 of the box body H will be described. The inner surface of the bottom wall portion 10 is formed in a thick plate shape (board shape) except for the four corners, and the thick plate portion 11 is a fixing portion for fixing devices K such as an earth leakage breaker, a breaker, and an outlet. F. The fixing portion F may have a fixing surface in which a large number of fixing holes for forcibly screwing screws 91 for fixing the devices K are arranged side by side in rows and columns. In this embodiment, the fixing portion F has the following configuration. That is, in the thick plate portion 11, the horizontal slits 12 are formed in a vertical row at a predetermined interval to constitute a “slit group”, and the “slit group” is formed in a plurality of rows along the width direction X (implementation). In the example, four rows) are formed, and vertical slits 13 are intermittently formed between each “slit group”. Since the horizontal and vertical slits 12 and 13 are continuously formed, the protrusions 14 are formed in both the adjacent portions of the horizontal slits 12 and the adjacent portions of the vertical and horizontal slits 12 and 13. The screws (tapping screws) 91 inserted into the slits 12 and 13 can be screwed into the protrusions 14 on both sides. With this structure, the devices K can be fixed to the bottom wall portion 10. The slit width of each of the horizontal and vertical slits 12 and 13 is gradually increased from the base portion of the thick plate portion 11 toward the surface, and the cut surface shape in the slit width direction is tapered due to the draft (see FIG. 4 to 7). In addition, in order to enable the cables E (power supply lines E ₁ and information lines E _{2 of the} equipment K) to be drawn into the box main body H at the four corners of the bottom wall 10 respectively. A plurality of circular knockout hole forming scheduled portions 15 are provided. Further, since the box body H is attached to the wiring pole P via the pole band 80, the screw 92 for fixing the pole band body 81 in the pole band 80 and the outer surface of the bottom wall 10 of the box body H. A plurality of screw hole formation scheduled portions 16 through which are inserted are also formed. In the present embodiment, a total of six screw hole formation scheduled portions 16 are formed on the left and right end portions of the bottom wall portion 10 at three equal intervals. 5 to 7 is a band portion in the pole band 80.

Next, the fixing of the devices K (devices K ₁ and K ₂ ) to the fixing portion F formed on the inner surface of the bottom wall portion 10 will be described with reference to FIGS. As described above, in the thick plate portion 11 on the inner surface of the bottom wall portion 10 which is the fixing portion F, the protrusions 14 are formed on the adjacent portions of the horizontal slits 12 and the adjacent portions of the horizontal and vertical slits 12 and 13. Is formed. Further, since the cut surfaces of the horizontal and vertical slits 12 and 13 in the slit width direction are tapered, when the screw 91 is inserted into the horizontal and vertical slits 12 and 13, the screw 91 has its shaft portion. Are screwed in while tapping them against the inner wall surfaces of the horizontal and vertical slits 12 and 13 until the heads of the screws 91 come into contact with the upper end surfaces of the protrusions 14 on both sides. . Accordingly, the screw 91 is first inserted into the insertion holes 71a and 72a of the fixing pieces 71 and 72 projecting from the devices K ₁ and K ₂ and then screwed into the horizontal and vertical slits 12 and 13, respectively. Thus, the devices K ₁ and K ₂ can be fixed to the fixing portion F of the bottom wall portion 10. Further, since the fixing portion F has a configuration in which the horizontal and vertical slits 12 and 13 are continuously formed as described above, the fixing positions of the devices K ₁ and K ₂ can be freely determined without restriction.

  Next, the device fixing plate L will be described with reference to FIGS. 3 and 4. The device fixing plate L is a substantially rectangular plate body with rounded four corners, and is composed of a fixing plate main body portion 41 and a mounting portion 43, and the depth width (length in the short direction) is the fixing portion F. Corresponds to the length from the upper end surface of the opening 30 to the opening surface of the opening 30 (see FIGS. 5 to 7). The device fixing plate L is formed of a resin material in the same manner as the device storage box B. A screw screw portion 42 is formed on the upper surface of the fixed plate main body portion 41. Further, the attachment portion 43 is provided downward from one of the side portions along the longitudinal direction of the fixed plate main body portion 41, and the device fixing plate L is attached to the fixed portion F of the bottom wall portion 10. It can be attached via a screw 93. In the screw threaded portion 42, vertical slits 42a along the short direction of the fixed plate main body portion 41 are formed in a horizontal row at predetermined intervals to form a vertical slit group, and the vertical slit group is formed in two upper and lower rows. The horizontal slit 42b is intermittently formed between the upper and lower vertical slit groups. Since the vertical and horizontal slits 42a and 42b are continuously formed, the adjacent portions of the vertical slits 42a and the vertical and horizontal slits 42a and 42b are formed in the same manner as the horizontal and vertical slits 12 and 13 of the fixed portion F. A protrusion 42c is formed in each adjacent portion. For this reason, the screws 94 inserted into the slits 42a and 42b can be screwed between the protrusions 42c on both sides. Further, the mounting portion 43 is provided with two insertion holes 44 through which the screws 93 are inserted along the longitudinal direction of the fixed plate main body portion 41. The insertion holes 44 may be round holes. In the embodiment, the insertion hole 44 has a vertically long slot shape with a slightly narrowed central portion.

  The attachment of the device fixing plate L to the fixing portion F will be described. As shown in FIG. 4, when the device fixing plate L is attached to the fixing portion F of the bottom wall portion 10, first, the attachment portion 43 side of the device fixing plate L is brought into contact with the planned attachment portion of the fixing portion F. Next, the screw 93 is inserted into the insertion hole 44 of the mounting portion 43 disposed on the lower side of the fixed plate main body 41, and the screw 93 is continuously inserted into the predetermined vertical slit 42a or the horizontal slit 42b by the driver D. What is necessary is just to forcibly screw in while tapping into the groove.

When the device K ₃ is attached to the device fixing plate L, it is inserted into the insertion hole 73a of the fixing piece 73 projecting from the device K ₃ in the same manner as fixing to the fixing portion F of the bottom wall portion 10. Subsequently, the device K ₃ can be fixed to the upper surface (screw screw portion 42) of the fixing plate body 41 of the device fixing plate L by screwing into the vertical and horizontal slits 42 a and 42 b of the screw screw portion 42. Since bis threaded join the club 42 is constituted by the slits 42a, 42b of the vertical and horizontal, it is possible to determine the fixing position of the screws threaded join the club 42 of the device K ₃ freely. Further, since the vertical slit 42 a is parallel to the depth direction Y, when fixing the device K ₃ to the device fixing plate L already attached to the fixing portion F, the screw 94 is attached to the fixing plate main body portion 41. It is not necessary to screw into the vertical slit 42a in a state of being perpendicular to the upper surface, and the screw 94 is screwed into the vertical slit 42a in a state where the screw 94 is inclined slightly in the depth direction Y from the vertical. Therefore, it is easy to fix the device K _{3 to} the device fixing plate L.

The timing of attaching the device K ₃ to the device fixing plate L may be after the device fixing plate L is attached to the fixing portion F. In that case, if the device K ₃ is larger than the device fixing plate L, the driver D is difficult to insert the screws 94 into the insertion hole 73a and interferes with the upright peripheral flange portion 31 and equipment K ₃ or the like. Therefore, after the device K ₃ is first fixed to the device fixing plate L, the device fixing plate L to which the device K ₃ is fixed may be attached to the fixing portion F. By fixing the device K ₃ to the device fixing plate L, there are the following advantages. That is, when the device K ₃ has a rectangular parallelepiped shape with a large height dimension, and the fixing piece 73 protrudes only along the width or depth instead of the height of the device K ₃ , the fixing portion Even if the device K ₃ is attached to F through the insertion hole 73a of the fixed piece 73, the height of the device K ₃ after attachment exceeds the height of the side wall portion 20 described later, and the device K ₃ is connected to the lid C. The opening 30 of the box body H cannot be closed due to interference. However, for example, the device K ₃ is arranged on the fixing plate main body 41 so that the height direction of the device K ₃ is perpendicular to the upper surface of the fixing plate main body 41 and fixed to the screw threaded portion 42. In addition, by fixing the device fixing plate L to the fixing portion F in such an arrangement that the upper surface is horizontal or perpendicular to the horizontal plane, the device K ₃ is arranged horizontally and attached to the fixing portion F. Become. Therefore, interference with equipment K ₃ and the cover C is avoided, can be closed without any problem box body H in the lid C.

As shown in FIG. 2, when the device fixing plate L is attached to the fixing portion F in such an arrangement that the upper surface of the fixing plate main body portion 41 is horizontal, it is fixed to the screw screw portion 42 on the upper surface. The device K ₃ is placed on the upper surface of the fixed plate main body 41 with the height direction parallel to the vertical direction Z (direction perpendicular to the horizontal plane). When the device fixing plate L is attached to the fixing portion F in the above arrangement state, the following effects can be obtained when the device K ₃ is fixed to the device fixing plate L attached to the fixing portion F in advance. Is done. That is, when the device K ₃ is fixed to the device fixing plate L, the device K ₃ can be stably placed on the horizontal upper surface of the fixing plate main body 41, so that the upper surface ( easily screwed into the screw 94 for fixing the device K ₃ bis threaded join the club 42), operation of fixing device K ₃ is facilitated. In addition, after the device K ₃ is fixed to the fixing portion F via the device fixing plate L, the device K ₃ is fixed in a state where it is placed on the horizontal upper surface of the fixing plate main body 41, so that it can be used for a long time. A stable fixed state is maintained over the entire range. As described above, the device fixing plate L can be attached to the fixing portion F by arranging the device fixing plate L so that the upper surface of the fixing plate body 41 is perpendicular to the horizontal plane.

Another advantage of fixing the device K ₃ to the device fixing plate L is that the device K ₃ is an outlet (not shown). When the device K ₃ (outlet) is fixed to the device fixing plate L, the plug J formed at the end of the power line E ₁ of another device K is inserted into the insertion port of the device K ₃ . Therefore, the rising direction from a device K ₃ of the power supply line E ₁ is parallel to the opening surface of the opening 30 of the box body H (i.e., parallel to the width direction X or the vertical direction Z) because the instrument K ₃ The rising portion of the power supply line E ₁ from the top does not interfere with the lid C that closes the opening 30 of the box body H.

Next, the side wall 20 of the box body H will be described with reference to FIGS. 1 and 2. As described above, the side wall portion 20 stands vertically with a predetermined height from the entire periphery of the bottom wall portion 10 having a substantially rectangular shape. An end portion of the opening 30 of the box body H of the side wall portion 20 enters the inside by a predetermined width over the entire circumference to form a peripheral flange portion 21. In the peripheral flange portion 21 having a predetermined width, a hinge connecting portion 22 for inserting a screw 95 is provided vertically along one longitudinal direction (right side in the front view in the present embodiment). A pair of butterfly plate couplers Q is attached to each of 22. The butterfly plate coupling tool Q has one piece arranged on the hinge coupling portion 22 of the peripheral flange portion 21 and the other piece arranged on the lid C, and is fixed with screws 95 at two locations. The power source line E ₁ and the information line E ₂ are collectively accommodated in the side wall portion 20 in the three directions (in the present embodiment, the three directions of the upper side, the lower side, and the left side in the front view) where the hinge connecting portion 22 is not provided. A plurality of circular knockout hole formation scheduled portions 23 for enabling insertion of end portions of the molding M to be protected into the box body H are provided. Further, in the side wall portion 20 on the side facing the hinge connecting portion 22 (left side in a front view), the locking portion 56 of the lid C is locked at the central portion in the longitudinal direction (vertical direction Z). A locking claw receiving portion 24 is formed. The locking claw receiving portion 24 is integrally formed with a standing peripheral flange portion 31 described later, and slightly protrudes toward the bottom wall portion 10. As shown in FIG. 1, the reinforcing cylindrical bodies 25 arranged along the height direction (depth direction Y) of the side wall portion 20 at the four corners of the bottom wall portion 10 reinforce the four corner portions of the box body H. Is to do.

  The standing peripheral flange portion 31 will be described with reference to FIGS. 1 and 5 to 7. As described above, the inner peripheral edge of the peripheral flange portion 21 in the side wall portion 20 forms the opening 30 and stands up at a predetermined height perpendicular to the opening surface over the entire periphery of the peripheral edge. An upright peripheral flange portion 31 is provided. The predetermined height is as follows. That is, the height dimension of the standing peripheral flange portion 31 along the vertical direction Z is constant along the vertical direction Z. On the other hand, as shown in FIG. 5 to FIG. 7, the height dimension of the standing peripheral flange portion 31 along the width direction X is substantially arc-shaped so that the center portion swells most in plan view, that is, in the width direction X. Both end portions are the same as the height dimension in the up-down direction Z, but the center portion in the width direction X has the highest dimension. The reason why the height portion is substantially arcuate in a plan view is that a main body plate portion 51 of a lid C described later is gently curved in a plan view and corresponds to the shape of the main body plate portion 51. is there. Further, the upper end portion 31a of the standing peripheral flange portion 31 that stands up perpendicularly to the opening surface of the opening portion 30 has a slight width and is bent 90 ° toward the outside. The width of the upper end portion 31 a corresponds to the width of the packing 55 fitted in the peripheral groove portion 54 formed on the back surface of the lid C. For this reason, when the lid C is closed, the upper end 31a abuts on the entire surface of the packing 55, so that the gap generated between the box body H and the lid C is closed. Intrusion of rainwater and dust into the main body H is prevented.

  Next, the lid C will be described with reference to FIGS. 1 and 5 to 7. The lid C has a configuration in which side plate portions 52 are integrally formed on the upper and lower end portions of the main body plate portion 51 that is gently curved in a plan view toward the back side (the bottom wall portion 10 side). . Both end portions in the width direction X of the main body plate portion 51 are sharply curved with respect to other portions. A hinge connecting portion 53 is formed on the side of the main body plate portion 51 that is connected to the box main body H, and a screw 95 for fixing the butterfly plate connecting tool Q is inserted into the hinge connecting portion 53. . One piece of the butterfly plate connector Q is fixed at the hinge connecting portion 53, and the other piece is fixed to the hinge connecting portion 22 of the peripheral flange portion 21 of the side wall portion 20 of the box main body H, whereby the lid The body C and the box body H are connected. A peripheral groove 54 for fitting the packing 55 is formed in a substantially rectangular shape on the back surface of the main body plate portion 51, that is, the surface facing the opening 30. The peripheral groove portion 54 is formed so as to be slightly along the outer periphery of the main body plate portion 51. The outer peripheral protrusion 54 a erected vertically from the back surface of the main body plate portion 51, and the peripheral protrusion 54 a. And a peripheral ridge 54b arranged inward by a predetermined width from the peripheral ridge 54a. That is, the width between the peripheral protrusions 54 a and 54 b is the groove width of the peripheral groove portion 54, and corresponds to the width of the packing 55. With the above configuration, when the equipment storage box device W is installed outdoors, even if rainwater enters the outer peripheral ridge 54a, the upper end 31a of the standing peripheral flange 31 and the packing 55 Therefore, it does not penetrate into the inner peripheral rim 54b. When the equipment storage box device W is installed indoors, a dustproof effect is achieved by the above configuration. Further, a locking portion 56 for maintaining the closed state of the opening 30 after the lid C is closed is attached to the central portion on the side facing the hinge connecting portion 53. The locking portion 56 includes a disk-shaped rotating portion 56 a, a substantially L-shaped locking claw portion 56 b integrally formed with the rotating portion 56 a, and a knob portion 56 c disposed on the front side of the main body plate portion 51. . The rotating portion 56a arranged on the back side of the main body plate portion 51 is connected to the front side knob portion 56c via a screw 96 penetrating the main body plate portion 51 at its axis, and rotates the knob portion 56c. Then, the rotating portion 56a rotates around the screw 96 and the locking claw portion 56b rotates and is locked by the locking claw receiving portion 24 in the side wall portion 20 of the box body H. Locked to the main body H. Further, if the knob portion 56c is rotated in the opposite direction, the locking claw portion 56b rotates counterclockwise together with the rotating portion 56a, and the lock is released. In the present embodiment, the locking and unlocking operations are performed only by 1/4 rotation and reverse rotation of the knob portion 56c, so that the convex portion formed on the side surface of the rotation portion 56a is locked. The two stoppers 56d are provided in the vicinity of the circumference of the rotating portion 56a so that their positions are at an angle of 90 ° with respect to the center of the rotating portion 56a. In the present embodiment, the knob portion 56 c is disposed so as to be accommodated in a hollow substantially inverted truncated cone-shaped recess 51 a formed on the front side of the main body plate portion 51. Since the knob portion 56c does not protrude with respect to the surface of the main body plate portion 51, contact and interference with the knob portion 56c are avoided, and the knob portion 56c is protected.

  Next, the embodiment of the present invention will be described with reference to FIGS. The closing prevention lever 60 is formed of a resin material in a substantially L shape, and one end projects from a portion of the back surface of the main body plate portion 51 of the lid C on the hinge connecting portion 53 side. In the state inserted in the attachment part 57, it is attached substantially perpendicularly with respect to the main-body board part 51, and it can be rotated by using the inserted side (rotation shaft part 62) as a rotation axis. Further, a linear portion on the side orthogonal to the rotation shaft portion 62 is defined as the contact portion 61. As shown in FIGS. 8 and 9, the blocking prevention lever 60 is rotated so that the contact portion 61 is in the direction of the rotation axis Qa of the butterfly plate connector Q (vertical direction Z in this embodiment). When in the substantially orthogonal arrangement, the abutment portion 61 abuts on the standing peripheral flange portion 31, and the distal end portion 61 a of the abutment portion 61 connects one piece of the butterfly plate connector Q to the hinge of the box body H. It arrange | positions between the two screws 95 currently fixed to the connection part 22 side.

  The closing prevention lever 60 when the lid C is opened and closed will be described with reference to FIGS. As shown in FIG. 5, the abutment portion 61 is arranged substantially in parallel with the rotational axis Qa direction (vertical direction Z) of the butterfly plate coupling tool Q fixed to the hinge coupling portions 22 and 53. In this case, since the abutting portion 61 does not abut on the standing peripheral flange portion 31, the lid C can freely rotate and can be opened and closed. Accordingly, when it is desired to completely close the lid C and close the opening 30 as shown in FIG. 5, the contact portion 61 may be arranged in the substantially parallel arrangement. Next, as shown in FIGS. 6 and 7, the blocking prevention lever 60 is rotated so that the contact portion 61 is disposed substantially orthogonal to the direction of the rotation axis Qa of the butterfly plate connector Q. In the case, the lid C is within the range from the state in which the lid C is completely open to the opening surface of the opening 30 to the state in which the abutment portion 61 abuts against the standing peripheral flange portion 31 of the box body H. The body C can be freely rotated and opened and closed (FIG. 7). Further, the lid C is closed, and when the lid C reaches a position close to orthogonal to the opening surface, the abutting portion 61 abuts on the standing peripheral flange portion 31. Even if the lid C is to be closed, the abutment portion 61 abuts against the standing peripheral flange portion 31 and interferes therewith, so that the rotation of the lid C is restricted and the lid C cannot be closed any more (FIG. 6). Therefore, if the blocking prevention lever 60 is rotated about the rotation shaft portion 62 and the contact portion 61 is disposed so as to be able to contact the upright peripheral flange portion 31, the opening portion of the box body H is opened. Thus, the opening angle of the lid C with respect to 30 can be prevented from becoming a certain angle or less.

  As described above, when the position of the blocking prevention lever 60 is such that the opening angle of the lid C does not close below a certain angle (regulation opening angle), the tip 61a of the contact portion 61 is a butterfly plate. It arrange | positions between the two screws 95 which are fixing the hinge connection part 22 side in the coupling tool Q. For example, when the opening angle of the lid C is within a range equal to or greater than the regulated opening angle and the lid C is closed violently due to a sudden gust of wind or an object collision, the blocking prevention lever 60 is rotated by the urging force. There is a risk that the lid C will be closed by rotating around the shaft 62. However, as shown in FIGS. 8 and 9, the front end 61 a of the contact portion 61 is caught on the head of one of the screws 95 regardless of which direction the blocking prevention lever 60 rotates. Further, the rotation of the closing prevention lever 60 is prevented. Therefore, when the lid C is restricted from being closed below the restriction opening angle with respect to the box body H, the restriction prevention lever 60 rotates and the restriction is released. It can be prevented more effectively.

  Further, the attachment position of the blocking prevention lever 60 is just above one hinge connecting portion 53 on the back surface of the main body plate portion 51 of the lid C. When the blocking prevention lever 60 is rotated, the contact portion 61 is moved. Even if it is arranged so as to abut against the standing peripheral flange portion 31, the blocking prevention lever 60 can be connected to the box main body H on the hinge connecting portion 22 side, that is, on the basis of the opening 30 of the box main body H. It is only disposed at the corner of the main body H, and does not enter the opening 30. For this reason, when the lid C is opened and various operations are performed in the box body H, the blocking prevention lever 60 hardly interferes with the operation. When the lid C is closed, the contact portion 61 is arranged substantially parallel to the direction of the rotation axis Qa (vertical direction Z) of the butterfly plate connector Q. The whole is accommodated in the box main body H so as to be opposed to each other through a slight gap without interfering with the standing peripheral flange portion 31. For this reason, interference with the equipment K accommodated in the equipment accommodating space V in the box main body H is also avoided.

In the embodiment of the device storage box device W, the device storage box B constituting the device storage box device W is arranged vertically and the hinge connecting portion 22 is on the right side and the lid C is on the right side when viewed from the front. In this case, it is attached to an outdoor wiring pole P so as to be opened. However, when the equipment storage box device W is installed on an indoor wall surface to accommodate information electrical equipment such as a hub and a router, the equipment storage box B is disposed horizontally and the hinge connection portion 22 is arranged. It is often attached in an arrangement in which the lid body C is turned upward to be lifted so that the lid body C is lifted. In some cases, the device storage box B is installed horizontally even outdoors. The equipment storage box device W when it is arranged horizontally will be described with reference to FIGS. 10 to 13. FIG. 10 is an overall perspective view of the device storage box device W that is disposed horizontally and attached to the wall surface R with the lid C open. FIG. 11 is a cross-sectional view taken along line A ₃ -A _{3 of} FIG. 10 showing the device fixing plate L attached to the fixing portion F with the driver D in the device storage box device W arranged horizontally. FIG. 12 is a side view of the device storage box device W in a state in which the periphery of the butterfly plate connector Q on the side of the blocking prevention lever 60 is partially cut away. When the device storage box device W is arranged horizontally, the longitudinal direction of the box body H is parallel to the width direction X. Even if the arrangement of the equipment storage box device W is rotated by 90 ° to change from the vertical arrangement to the horizontal arrangement, the horizontal and vertical directions of the horizontal slit 12 and the vertical slit 13 in the fixing portion F of the bottom wall portion 10 are interchanged. The fixing method of the devices K or the device fixing plate L to the fixing portion F of the wall portion 10 is not changed at all.

  When the device fixing plate L is attached to the fixing portion F so that the upper surface of the fixing plate main body 41 is horizontal in the horizontally-arranged device storage box B, the following operational effects are obtained. As shown in FIG. 11, first, in the fixing portion F, the horizontal slit 12 and the vertical slit 13 are interchanged. In this embodiment, four rows) are formed, and the horizontal slits 13 (original vertical slits 13) are intermittently formed between the slit groups. On the other hand, in the device fixing plate L attached to the fixing portion F, the shape of the insertion hole 44 formed in the attaching portion 43 is a vertically long slot whose center portion is narrowed. Therefore, the screw 93 can be inserted from the inclined direction instead of the vertical direction with respect to the fixing portion F, and the device fixing plate L can be attached to the fixing portion F. That is, since the insertion hole 44 is vertically long, the screw 93 is inserted into the insertion hole 44 in a state where the screw 93 is slightly inclined in the vertical direction Z from the vertical direction (depth direction Y) with respect to the upper end surface of the fixing portion F. Furthermore, it is possible to screw into the vertical slit 12 (original horizontal slit 12) extending in the vertical direction Z while maintaining the inclined state, so that the screw 93 stands upright with respect to the fixed portion F. It is not necessary to screw into the vertical slit 12 in the state of being made. For this reason, even if it is difficult to attach with the screw 93 while maintaining the vertical direction with respect to the upper end surface of the fixed portion F, for example, near the peripheral portion of the fixed portion F where the driver D interferes with the side wall portion 20. The device fixing plate L can be easily attached, and the working efficiency is improved.

  Further, even when the device storage box device W is disposed horizontally, the closing prevention lever 60 can restrict the lid C from closing the opening 30 below a predetermined opening angle. That is, when the closed device storage box device W attached to the wall surface R is kept open, first, the knob portion 56c of the locking portion 56 at the center of the lower end portion of the lid C. To release the locked state, open the lid C so as to lift it up, rotate the blocking prevention lever 60 around the rotation shaft portion 62, and the abutment portion 61 is brought into the standing peripheral flange portion 31. It arrange | positions so that it can contact | abut. As a result, even if the lid C rotates downward due to gravity and falls, and the opening 30 of the box body H is likely to be closed, the contact portion 61 contacts the standing peripheral flange portion 31. The lid C does not fall further downward, and the opening angle of the lid C with respect to the opening 30 can be prevented from becoming a certain angle or less. Therefore, when the blocking prevention lever 60 is rotated and the contact portion 61 is arranged in a substantially vertical direction with respect to the rotation axis Qa of the butterfly plate connector Q, the lid body C rotates downward due to gravity. Even if it moves, the abutting part 61 abuts on the standing peripheral flange part 31 and does not close the opening 30, so that various operations in the box body H can be carried out efficiently.
