Description

Technical Field

[0001] The utility model relates to the field of distribution box devices, and particularly relates to a distribution box cover and a distribution box with the distribution box cover. Background Art

[0002] For a distribution box, especially a distribution box embedded in a wall, in order to improve its aesthetics and safety, a distribution box cover is generally used to shield components such as switches, circuit breakers, and fuses in the bottom box. Specifically, the distribution box cover includes a face frame and a face cover. The face frame surrounds the bottom box, and the face cover covers the front side of the face frame and the bottom box, thereby shielding both the face frame and the components in the bottom box.

[0003] In some existing distribution boxes, one side of the face cover is rotatably connected to the face frame by a pivot structure, and the other side can be rotated to open or close. In some other existing distribution boxes, separable shaft and bushing structures can also be installed on both sides. In this way, the face cover can be opened from the left or the right.

[0004] However, existing distribution box covers, especially those that can be opened on both sides, have the problem that it is difficult to reliably indicate whether the face cover is fully closed. Summary of the Invention

[0005] Aiming at the above problems, the utility model provides a distribution box cover, which can reliably indicate whether the face cover is fully closed by using a simple mechanical structure.

[0006] The distribution box cover provided by the first aspect of the utility model includes a face frame, a face cover, and a rotating connection assembly. The face cover covers the front side of the face frame, and the face cover is rotatably connected to the face frame by the rotating connection assembly. The rotating connection assembly includes a first rotating connection member and a second rotating connection member that are rotatably connected and separable from each other. The first rotating connection member is arranged on the face frame, and the second rotating connection member is arranged on the face cover. The second rotating connection member includes a rotating shaft and a indicating plate. The rotating shaft is arranged at the end of the face cover; the indicating plate has a first connection portion and a second connection portion suitable for connecting with the rotating shaft. When the indicating plate is connected to the rotating shaft by the first connection portion, the indicating plate is shielded by the face cover. When the indicating plate is connected to the rotating shaft by the second connection portion, the indicating plate protrudes out of the end of the face cover; the indicating plate also has an abutting portion. In the final stroke of the face cover rotating relative to the face frame to be fully closed, the abutting portion abuts against the first rotating connection member to drive the indicating plate to change from being connected to the rotating shaft by the second connection portion to being connected to the rotating shaft by the first connection portion.

[0007] Since the first rotating connector and the second rotating connector are rotatably connected, when the first rotating connector and the second rotating connector are rotatably connected, the rotating connection assembly provided on the pivot side can be used as a pivot. And because the first rotating connector and the second rotating connector are separable, when a force exceeding the threshold is applied to this side where the rotating connection assembly is provided, the first rotating connector and the second rotating connector can be disassembled from each other, so that the face cover can be opened from this side. In the above way, the user can not only use the rotating connection assembly as a pivot, but also open the face cover from this side. In addition, since in the final stroke when the face cover rotates relative to the face frame to a fully closed state, the display plate only changes from being connected to the rotating shaft by the second connecting portion to being connected to the rotating shaft by the first connecting portion, when it is fully closed, the display plate retracts to a position blocked by the face cover, and when the face cover is not fully closed, the display plate protrudes from the end of the face cover, so that it is easily observable by the user from the front side. In the above way, the user can be timely prompted by using the simple mechanical device of the display plate when the face cover is not fully closed.

[0008] Optionally, the display plate includes a clamping portion, at least a part of the outer edge of the clamping portion is configured as a circular outer edge, the first connecting portion is a first card slot penetrating the clamping portion along the axial direction of the circular outer edge, the second connecting portion is a second card slot, the second card slot penetrates the clamping portion parallel to the axial direction, and the second card slot is arranged inside the first card slot and communicated with the first card slot. In the above way, with a relatively simple structure, two stable clamping positions of the display plate and a quick and reliable switching between the two stable clamping positions can be provided.

[0009] Optionally, another part of the outer edge of the clamping portion is configured as a recessed portion that is recessed towards the center of the clamping portion relative to the circular outer edge, and the abutting portion is the recessed portion.

[0010] Optionally, the clamping portion is provided with a rotating shaft card entrance at the end away from the first card slot of the second card slot. During the assembly process, the shaft portion of the rotating shaft can be snapped into the second card slot through the rotating shaft card entrance, which is convenient for the assembly of the display plate.

[0011] Optionally, the rotating shaft includes a shaft portion and at least two cylindrical portions. The two ends of the shaft portion are respectively fixedly connected to the face cover. The at least two cylindrical portions are spaced apart on the shaft portion. The display plate is clamped to the shaft portion between the two cylindrical portions by using the first card slot or the second card slot. In the above way, the clamping position of the display plate can be maintained between the two cylindrical portions. On the one hand, the clamping is more stable, and the movement of the display plate in the inner and outer directions is more stable. On the other hand, this structure has the characteristics of rotational symmetry and axial symmetry, and can be used by flipping up and down or left and right.

[0012] Optionally, the first rotating connecting member includes a bushing rotatably connected to the rotating shaft. The bushing has at least two gripping portions spaced apart from each other, and the gripping portions overlap at least partially with a part of the cylindrical portion and a part of the clamping portion in the axial direction. In this way, both the cylindrical portion and the clamping portion can abut against the gripping portions of the bushing when the face cover is opened and closed. The cylindrical portion can drive the inner and outer movement of the bushing, and further, the inner and outer movement of the bushing can drive the display board to move in the inner and outer directions. In addition, the front end of the gripping portion can also directly abut against the abutting portion of the display board, and the display board is directly driven by the gripping portion to move in the inner and outer directions.

[0013] Optionally, the display board further includes a display portion and a display board connecting portion. The display portion is the part of the end of the display board that can extend or retract from the face cover. The display board connecting portion passes through between two spaced-apart gripping portions to connect the display portion and the clamping portion.

[0014] Optionally, the gripping portion is configured to extend from the rear side of the cylindrical portion in a manner of extending outward and then bending inward to the front side of the cylindrical portion.

[0015] Optionally, the display portion further includes a bushing abutting portion located on the side of the gripping portion away from the clamping portion when the face cover is closed. During the opening process of the face cover, the bushing abutting portion abuts against it when the gripping portion extends outward, so as to reset the display portion to the position protruding outward from the end of the face cover.

[0016] Optionally, the face cover has a display board limiting opening for the display portion to extend or retract. The display board limiting opening can further define the moving direction of the display board, making the movement of the display board more stable.

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0032] Figure 1This is a schematic structural view when the distribution box cover 100 in this embodiment is closed. Refer to Figure 1 , in the first embodiment of the present utility model, a distribution box cover 100 of a distribution box is disclosed. The distribution box cover 100 includes a face frame 1 ( Figure 1 not shown in the figure), a face cover 2, and four sets of rotational connection components 3. The rotational connection components 3 are used to rotatably connect the face frame 1 and the face cover 2. One feature of the distribution box cover 100 provided in this embodiment is that among the four sets of rotational connection components 3, two sets of rotational connection components 3 are arranged at the first end of the face frame 1 / face cover 2 ( Figure 1 the two sets of rotational connection components 3 at the first end in the figure are blocked and not shown), and the other two sets of rotational connection components 3 are arranged at the second end of the face frame 1 / face cover 2. In this embodiment, between the two components of each set of rotational connection components 3, they can be both rotatably connected and disassembled, so that the face cover 2 can be opened from the left side or the right side, so as to flexibly cope with different installation environments.

[0033] Figure 2 This is a schematic structural view when the distribution box cover 100 in this embodiment is opened with the two sets of rotational connection components 3 on the right side as the pivot, Figure 3 This is a schematic structural view when the distribution box cover 100 in this embodiment is opened with the two sets of rotational connection components 3 on the left side as the pivot.

[0034] Refer to Figures 1-3 , in this embodiment, the center of the face frame 1 is open and connected to the bottom box of the distribution box (not shown in the figure). The bottom box is for components such as switches, circuit breakers, and fuses to be arranged therein. The face cover 2 covers the front side of the face frame 1 and is used to block the components in the face frame 1 and the bottom box. In this embodiment, the face frame 1 is a rectangular frame. Correspondingly, the face cover 2 is also a rectangular panel, and the outer peripheral dimension of the face cover 2 is slightly larger than the outer peripheral dimension of the face frame 1, so as to completely block the components in the face frame 1 and the bottom box.

[0035] The outer edge of the distribution box cover 100 has opposite first and second ends along the Figures 1-3 left - right direction in the figure. In order to improve the stability of the rotational connection, the number of sets of rotational connection components 3 arranged at the first and second ends is two sets each. In other embodiments of the present utility model, the number of rotational connection components 3 arranged at the first and second ends can be flexibly adjusted. Specifically, it can be set that one set is arranged at each of the first and second ends or three or more sets are arranged.

[0036] Taking the Figure 1 inner - outer direction defined in the figure as the inside - outside direction, in this embodiment, each set of rotational connection components 3 is arranged at the outer end in the inside - outside direction. Refer to Figures 1-3, in this embodiment, the rotating connection assembly 3 provided includes a separable first rotating connector 301 and a second rotating connector 302. The first rotating connector 301 is disposed at the outer end of the front frame 1, and the second rotating connector 302 is disposed at the outer end of the front cover 2.

[0037] In this embodiment, the user can use Figure 1 the two sets of rotating connection assemblies 3 on the left side in Figure 1 as pivots, apply force on the right side to separate the first rotating connector 301 and the second rotating connector 302 of the two sets of rotating connection assemblies 3 on the right side from each other, so as to open the front cover 2 from the right side; the user can also use

[0038] Refer to Figure 2 , when the distribution box cover 100 opens the front cover 2 with the two sets of rotating connection assemblies 3 on the right side as pivots, the first rotating connector 301 and the second rotating connector 302 of the rotating connection assembly 3 on the right side still remain connected. However, since the user applies a forward pulling force on the left side of the front cover 2 when opening the front cover 2, the first rotating connector 301 and the second rotating connector 302 of the rotating connection assembly 3 on the left side are separated from each other. The first rotating connector 301 still remains fixed at the end of the front cover 2, while the second rotating connector 302 is still disposed at the end of the front frame 1.

[0039] Similarly, refer to Figure 3 , Figure 3 when the front cover 2 of the distribution box cover 100 in

[0040] Figure 4 is opened with the two sets of rotating connectors on the left side as pivots, the first rotating connector 301 and the second rotating connector 302 of the two sets of rotating connection assemblies 3 on the left side still remain in rotational connection, while the first rotating connector 301 and the second rotating connector 302 of the two sets of rotating connection assemblies 3 on the right side are separated from each other.

[0041] Refer to Figure 4, in this embodiment, the first rotating connector 301 includes a bushing 32, a bushing fitting 34, and a spring 33. The bushing 32 is a sheet metal part obtained by integrally forming a metal sheet through processes such as folding and punching, and has a certain elasticity. The bushing 32 at least includes a spring abutting portion 320, a sliding portion 321, and a holding portion 322. Among them, the spring abutting portion 320 is the part for the spring 33 to abut. The sliding portion 321 is a metal sheet extending in the inner and outer directions and constitutes the main body portion of the bushing 32. The sliding portion 321 can slide in the bushing fitting 34. Therefore, when opening and closing the face cover 2 from the end shown in Figure 4 , the bushing 32 can generate a displacement in the inner and outer directions to avoid the forward and backward movement of the rotating shaft 303.

[0042] The holding portion 322 is provided at the left end of the bushing 32, is connected to the sliding portion 321, and partially surrounds the outer periphery of the rotating shaft 303. Specifically, in this embodiment, the inner side wall of the holding portion 322 is in an arc shape matching the outer edge shape of the cylindrical portion 304 of the rotating shaft 303. This shape can facilitate the rotation of the rotating shaft 303 in the bushing 32 with less obstruction.

[0043] In this embodiment, referring to Figure 5 , after the holding portion 322 extends outward from the rear inner side of the rotating shaft 303, it turns inward along the outer edge of the rotating shaft 303 and then extends to the outer front side of the rotating shaft 303. The holding portion 322 with this shape has at least the following advantages:

[0044] When Figure 5 the end shown in is used as the pivot, the holding portion 322 with this shape can maintain the surrounding and contact of a large circumferential range of the rotating shaft 303, so that the rotation process is relatively stable and smooth.

[0045] When Figure 5 the end shown in is opened from the closed state, as the face cover 2 is opened, the cylindrical portion 304 of the rotating shaft 303 will move forward along the circumferential rotation trajectory from the position indicated by the solid line to the position indicated by the dashed line. At the solid line position, the cylindrical portion 304 of the rotating shaft 303 abuts against the portion of the holding portion 322 located at the outer front side of the rotating shaft 303. The stress generated by the abutment has a component towards the outside, thereby driving the bushing 32 to move outward to avoid the entry and exit of the rotating shaft 303.

[0046] And when Figure 5 the end shown in is closed from the open state, the rotating shaft 303 will move backward along the circumferential rotation trajectory from the position indicated by the dashed line to the position indicated by the solid line. At the dashed line position, the rotating shaft 303 abuts against the front end of the holding portion 322. The abutting force of the rotating shaft 303 on the front end of the holding portion 322 has a component towards the outside, thereby driving the bushing 32 to move outward to avoid the entry and exit of the rotating shaft 303.

[0047] In the above manner, when the opening / closing cover 2 is opened and closed, the rotating shaft 303 can be pressed against the bushing 32, generating a force that drives the bushing 32 to move outward, thereby avoiding the entry and exit of the rotating shaft 303. Since the bushing 32 is slidably mounted in the bushing fitting 34, the outward movement of the bushing 32 is not restricted, and the entry and exit of the rotating shaft 303 can be effectively avoided. On the other hand, due to the presence of the spring 33, after the rotating shaft 303 is completely disengaged from the bushing 32, the spring 33 can reset the position of the bushing 32, ensuring that when the cover 2 is closed next time, the bushing 32 can be in a position where part of the thrust when the rotating shaft 303 enters can be converted into a force that causes the bushing 32 to move outward. When the rotating shaft 303 is in a closed state partially surrounded by the bushing 32, the spring 33 can pull the bushing 32 inward, causing the bushing 32 to tightly press against the rotating shaft 303, ensuring the stability of the position of the rotating shaft 303 when rotating about the rotating connection assembly 3 as a pivot, and ensuring that the rotating shaft 303 is not easily detached from the bushing 32.

[0048] Figure 6 is a schematic structural view (stereogram) of the rotating connection assembly 3 in this embodiment. Refer to Figure 6 In this embodiment, the second rotating connector 302 of the rotating connection assembly 3 includes a rotating shaft 303 and a display plate 306.

[0049] Among them, the rotating shaft 303 is the mechanism that rotates and connects with the bushing 32, and its specific structure is as Figure 7 shown. Refer to Figure 7 As shown, the rotating shaft 303 includes a shaft portion 305 and two cylindrical portions 304. Both ends of the shaft portion 305 are fixedly connected to the cover 2, thereby fixing the rotating shaft 303 in the cover 2 in the width direction. The two cylindrical portions 304 are spaced apart from each other and are coaxially arranged with the shaft portion 305.

[0050] The display plate 306 is used to prompt the user whether the cover 2 is completely closed. Specifically, when the cover 2 is completely closed and when the cover 2 is not completely closed, the user can observe different change states of the display plate 306 from the front side, thereby distinguishing whether the cover 2 is completely closed. The specific structure of the display plate 306 is as Figure 8 shown.

[0051] In this embodiment, when the display board 306 is completely closed by the face cover 2, that is, when the first rotating connecting member 301 and the second rotating connecting member 302 are rotationally connected, the display board 306 is connected to the shaft portion 305 by the first card slot 307. At this time, the display board 306 will be blocked by the face cover 2 and cannot be observed by the user in the front. When the face cover 2 is not completely closed, the display board 306 will be connected to the shaft portion 305 by the second card slot 308. At this time, the display board 306 will partially protrude from the end of the face cover 2 and can be observed by the user in the front. Further, the part of the display board 306 that can protrude from the end of the face cover 2 can be configured to have a different color from the face cover 2, so that the display board 306 can be more clearly observed by the user.

[0052] Reference Figure 8 , the display board 306 includes a clamping portion 309, an abutting portion 310, a display board connecting portion 311 and a display portion 312. Among them, the clamping portion 309 is used to clamp the display board 306 between the shaft portions 305 between the two cylindrical portions 304 of the rotating shaft 303. The dimension in the width direction of the clamping portion 309 matches the distance between the two cylindrical portions 304, so that it can be stably clamped at the position between the two cylindrical portions 304 without shaking up and down.

[0053] A part of the outer edge of the clamping portion 309 is a circular outer edge 313, and the other part is a recessed portion (i.e., the abutting portion 310). Specifically, reference Figure 8 , the left outer edge of the clamping portion 309 is a circular outer edge 313, and the right outer edge of the clamping portion 309 is a recessed portion that is recessed relative to the circular outer edge 313 towards the center of the clamping portion 309. The recessed portion is used to abut against the front end of the shaft sleeve 32 and limit the movement path of the front end of the shaft sleeve 32.

[0054] In this embodiment, the clamping portion 309 is a pair of claws with three teeth, and two card slots are formed between the three teeth. The two card slots, namely the first card slot 307 (also known as the first connecting portion) and the second card slot 308 (also known as the second connecting portion), respectively provide two carding positions for the shaft portion 305 to be clamped. Both the first card slot 307 and the second card slot 308 are card slots with inner walls configured as circular arc surfaces to facilitate the rotation of the shaft portion 305 therein.

[0055] The first card slot 307 is coaxial with the circular outer edge 313 of the clamping portion 309. The first card slot 307 is rotationally engaged with the shaft portion 305 when the first rotating connecting member 301 and the second rotating connecting member 302 are rotationally connected, so that when the rotating connection assembly 3 is used as a pivot, the rotation is smoother and more stable.

[0056] Specifically, the first card slot 307 penetrates through the clamping portion 309 along the axial direction of the circular outer edge 313. The extending direction of the second card slot 308 is parallel to that of the first card slot 307, but is arranged off-axis from the circular outer edge 313 of the clamping portion 309, and is specifically arranged inside the first card slot 307. The first card slot 307 and the second card slot 308 are interconnected. The shaft portion 305 can move from the first card slot 307 into the second card slot 308, or can move from the second card slot 308 into the first card slot 307. In this way, with a relatively simple structure, the display board 306 can provide two clamping positions that can stably clamp the shaft portion 305 and can rotate relative to the shaft portion 305. Moreover, the shaft portion 305 can be quickly and reliably switched between the two clamping positions.

[0057] In addition, a rotating shaft card entrance 314 is provided at the left end of the clamping portion 309 in the second card slot 308. During the assembly process, the shaft portion 305 of the rotating shaft 303, specifically, the shaft portion 305 between the two cylindrical portions 304, can be snapped into the second card slot 308 via the rotating shaft card entrance 314, and then the display board 306 can be conveniently assembled onto the rotating shaft 303.

[0058] The display portion 312 is the component of the display board 306 for performing the display function, including the part of the display board 306 that can extend out to protrude from the end portion of the face cover 2. In this embodiment, the display portion 312 specifically extends out via the display board limiting port 201 on the face cover 2 (refer to Figure 6 ). Refer to Figure 8 , the part of the display board 306 that can extend out from the display board limiting port 201 is the flat plate 315. When installed on the face cover 2, this part of the flat plate 315 can move in the inner and outer directions of the face cover 2. Specifically, the extending direction of the flat plate 315 is parallel to the connection direction of the center lines of the first card slot 307 and the second card slot 308. Thus, when the shaft portion 305 switches the clamping position between the first card slot 307 and the second card slot 308, the flat plate 315 will also move correspondingly in the inner and outer directions, so as to extend out or retract from the end portion of the face cover 2, creating a visual difference that can be observed by the user in front of the face cover 2, and playing a role in prompting the user when the face cover 2 is fully closed or not fully closed.

[0059] In addition to the flat plate 315, the display portion 312 further includes a shaft sleeve abutting portion 316 extending in the front-back direction. When the face cover 2 is opened from the fully closed state, the shaft sleeve 32 can move outward under the drive of the cylindrical portion 304, and then abut against the shaft sleeve abutting portion 316, pushing the display board 306 outwards. Specifically, the state of the display board 306 changes from clamping the shaft portion 305 using the first card slot 307 to clamping the shaft portion 305 using the second card slot 308.

[0060] The display board connecting portion 311 is used to connect the clamping portion 309 and the display portion 312. In this embodiment, the clamping portion 309 has a pair of clamping claws, and correspondingly, the display board connecting portion 311 has two. One ends of the two display board connecting portions 311 are connected to the bushing abutting portion 316 of the display portion 312, and the other ends are respectively connected to the tails of the two clamping claws.

[0061] Figure 9 Fig. shows a schematic diagram of the assembly dimension relationship among the display board 306, the bushing 32 and the rotating shaft 303 of the rotating connection assembly 3 in this embodiment. Refer to Figure 9 , the bushing 32 has two gripping portions 322 arranged at intervals from each other. The display board connecting portion 311 passes through between the two gripping portions 322 to connect the display portion 312 and the clamping portion 309. The width of the clamping portion 309 is substantially equal to the width of the shaft portion 305 between the two cylindrical portions 304, and is engaged with the shaft portion 305 between the two cylindrical portions 304 in a matching manner. The width of the display portion 312, especially the width of the bushing abutting portion 316, is wider than the width of the clamping portion 309, so that the bushing 32 can abut against the bushing abutting portion 316 to drive the display board 306 to move outward, and reset it to a position protruding outward from the end of the face cover 2.

[0062] In the width direction (i.e., the axial direction of the circular outer edge 313 of the clamping portion 309), the two gripping portions 322 respectively overlap with the regions near the middle of the two cylindrical portions 304, and the extending range of the two gripping portions 322 in the width direction also overlaps with a part of the clamping portion 309. In this way, both the cylindrical portion 304 and the clamping portion 309 can abut against the front ends of the gripping portions 322 of the bushing 32 when the face cover 2 is opened and closed. The cylindrical portion 304 can drive the bushing 32 to move inward and outward. Further, the inward and outward movement of the bushing 32 can drive the display board 306 to move inward and outward. In addition, the front end of the gripping portion 322 can also directly abut against the abutting portion 310 of the display board 306, and the display board 306 is directly driven by the gripping portion 322 to move in the inward and outward directions.

[0063] The following will be combined with Figure 10 and Figure 11 to introduce the action mode of the display board 306 during the process of opening and closing the face cover 2 in this embodiment. Figure 10 Fig. is a schematic structural diagram (cross-sectional view) of the rotating connection assembly 3 when the face cover 2 is slightly opened or the face cover 2 is not completely closed, that is, when the first rotating connecting member 301 and the second rotating connecting member 302 are separated. Figure 11 Fig. is a schematic structural diagram (cross-sectional view) of the rotating connection assembly 3 when the face cover 2 is completely closed, that is, when the first rotating connecting member 301 and the second rotating connecting member 302 are rotationally connected.

[0064] <The final stroke of closing the face cover 2>

[0065] In the final stage of closing the cover 2, the front end of the holding portion 322 of the bushing 32 will first abut against the outer rear surface of the cylindrical portion 304 of the rotating shaft 303 and against the abutting portion 310 of the indicating plate 306. In this stroke range, the shaft portion 305 is snapped into the second card slot 308, and the outer edge locus of the abutting portion 310 of the indicating plate 306 substantially coincides with the shape of the outer rear surface of the cylindrical portion 304.

[0066] Reference Figure 10 , during the process that the front end of the holding portion 322 moves past the outer end of the cylindrical portion 304 and comes into contact with the outer front surface of the cylindrical portion 304, the bushing 32 moves inward, and the bushing 32 and the bushing abutting portion 316 are separated from each other or the mutual acting force decreases. Since the abutting portion 310 of the indicating plate 306 is located at a more outward position than the outer front surface of the cylindrical portion 304, the bushing 32 will directly abut against the abutting portion 310 of the indicating plate 306, and mainly apply force to the abutting portion 310 of the indicating plate 306, without contacting the cylindrical portion 304 of the rotating shaft 303 or applying less force to the cylindrical portion 304 of the rotating shaft 303. Correspondingly, the inward traction force exerted by the spring 33 on the bushing 32 will be applied to the abutting portion 310 of the indicating plate 306, thereby driving the indicating plate 306 to move inward. Specifically, the indicating plate 306 moves from being snapped into the shaft portion 305 by means of the second card slot 308 to being snapped into the shaft portion 305 by means of the first card slot 307, that is, from the Figure 10 shown snapping position to the position as shown in Figure 11 the snapping position shown.

[0067] In the above manner, in the final stroke of the face cover 2 rotating relative to the face frame 1 until it is completely closed, the bushing 32 abuts against the abutting portion 310 of the display board 306, driving the display board 306 to change from being connected to the rotating shaft 303 by means of the second card slot 308 to being connected to the rotating shaft 303 by means of the first card slot 307. Furthermore, it drives the display board 306 to move inward when the face cover 2 is completely closed, retracting to a position completely covered by the end of the face cover 2, that is, a position where the user cannot observe it from the front of the face cover 2, thereby reminding the user that the face cover 2 is completely closed. When the face cover 2 is not completely closed, the display board 306 is located at a position protruding outward from the end of the face cover 2, and the user can observe the display board 306 from the front of the face cover 2, thereby reminding the user that the face cover 2 is not completely closed. In addition, because in the final stroke of the face cover 2 rotating relative to the face frame 1 until it is completely closed, the display board 306 only changes from being clamped to the rotating shaft 303 by means of the second card slot 308 to being clamped to the rotating shaft 303 by means of the first card slot 307. Therefore, when it is completely closed, the display board 306 retracts to a position blocked by the face cover 2, and when the face cover 2 is not completely closed, the display board 306 will protrude outward from the end of the face cover 2, thus being easily observable by the user from the front side. In the above manner, the simple mechanical device of the display board 306 can be used to prompt the user in a timely manner when the face cover 2 is not completely closed.

[0068] <Initial stroke of opening the face cover 2>

[0069] Before the face cover 2 is opened, the first rotating connecting member 301 and the second rotating connecting member 302 are in the position as shown in Figure 11 As shown. As the face cover 2 is opened, the cylindrical portion 304 abuts against the bushing 32 and applies an outward force to the bushing 32, pulling the bushing 32 outwards. As the bushing 32 moves outwards, the outer surface of the gripping portion 322 of the bushing 32 will abut against the bushing abutting portion 316 of the display board 306. The continuously outward moving bushing 32 can drive the display board 306 to move from the position shown in Figure 11 As shown to a position where it is clamped to the shaft portion 305 by means of the second card slot 308, thereby resetting the display board 306.

[0070] In this embodiment, by adding a simple structure of the display board 306, the user can be prompted in a timely manner when the face cover 2 is not completely closed, preventing the user from opening the face cover 2 from the other side when the rotating connection assembly 3 on one side is not connected in place, which may easily cause the face cover 2 to fall off. Moreover, the distribution box cover 100 provided in this embodiment is a symmetric structure that can be turned up and down or left and right and still remain usable. The four rotating connection assemblies 3 used can also adopt the same structure, which is beneficial to improving the generalization degree of the rotating connection assembly 3.

[0071] It should be noted that although the technical solution of the distribution box cover 100 provided in this embodiment is particularly suitable for improving the user experience of the distribution box cover 100 that can be opened on both sides, and uses a simple mechanical structure to reliably indicate whether the face cover 2 is fully closed, it is not limited to being only applied to the distribution box cover 100 that can be opened on both sides. The scheme of adding the indicating board 306 in this embodiment can also be applied to some distribution box covers 100 that are opened unidirectionally to give users a prompt when the face cover 2 is fully closed or not fully closed.

[0072] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
