DETAILED DESCRIPTION

[0032] In order to make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a number of ways beyond the specific embodiments described and claimed herein. It is therefore intended that the present application not be limited in scope to the specific embodiments disclosed.

[0033] Reference will now be made to Figures 1 to 4 An embodiment of the present application provides a power distribution encryption box 10 convenient to maintain, comprising a control module 110, an accommodating shell 120, a top plate 130, a side plate 140 and a linkage mechanism 150. The accommodating shell 120 is provided with an accommodating cavity 121 for accommodating the control module 110. A top wall of the accommodating cavity 121 is provided with a first opening, and the top plate 130 is rotatably arranged at the first opening. A side wall of the accommodating cavity 121 is provided with a second opening, and the side plate 140 is rotatably arranged at the second opening. The linkage mechanism 150 is connected between the top plate 130 and the side plate 140 and used to drive the top plate 130 and the side plate 140 to rotate simultaneously.

[0034] In the maintenance-facilitating power distribution encryption box 10 described above, when the top plate 130 and the side plate 140 are respectively covered on the first opening and the second opening, the accommodating cavity 121 can form a relatively closed environment to protect the control module 110 placed in the accommodating cavity 121. Since the top plate 130 can be rotatably covered on the first opening, the side plate 140 can be rotatably covered on the second opening, the linkage mechanism 150 is connected between the top plate 130 and the side plate 140, and it can make the top plate 130 and the side plate 140 rotate simultaneously, in other words, under the action of the linkage mechanism 150, when one of the top plate 130 or the side plate 140 rotates, the other one rotates simultaneously. Therefore, when the control module 110 needs to be taken out from the accommodating cavity 121, only one of the top plate 130 or the side plate 140 is rotated to make the top plate 130 and the side plate 140 simultaneously separate from the first opening and the second opening. It can be seen that when the maintenance-facilitating power distribution encryption box 10 is disassembled, the operation process is relatively convenient, and the labor efficiency is improved.

[0035] Please refer to Figure 1 , Figure 2 and Figures 5 to 7 In an embodiment, the maintenance-facilitating power distribution encryption box 10 further comprises a side rotating shaft 160. The side rotating shaft 160 is arranged on the side plate 140, and the side rotating shaft 160 is rotatably connected with the shell wall of the accommodating shell 120 to make the side plate 140 coverable on the second opening. The linkage mechanism 150 comprises a telescopic piece 151 and a sliding block 152. The top plate 130 is provided with a fixed block 170. The fixed block 170 is provided with a guide portion 171, and the sliding block 152 is movably arranged on the guide portion 171. One end of the telescopic piece 151 is rotatably connected with the sliding block 152, and the other end of the telescopic piece 151 is fixedly connected with the side rotating shaft 160. In this way, the telescopic piece 151 is configured as a rotating piece with the side rotating shaft 160 as the center. Therefore, as shown in Figure 1 and Figures 5 to 7 When the top plate 130 rotates around its rotating shaft and drives the fixed block 170 to rotate, the sliding block 152 is limited by the side wall of the accommodating shell 120 and cannot rotate, and under the action of the guide portion 171, the sliding block 152 can move up and down in the vertical direction. Since the telescopic piece 151 is telescopic and rotatably connected with the sliding block 152, the movement of the sliding block 152 in the vertical direction can be converted into the rotation of the telescopic piece 151 with the side rotating shaft 160 as the center. And since the telescopic piece 151 is fixedly connected with the side rotating shaft 160, the side rotating shaft 160 can be rotated to make the side plate 140 coverable on the second opening.

[0036] Alternatively, the telescopic piece 151 can be directly fixedly connected with the side rotating shaft 160; or the telescopic piece 151 can be fixedly connected with the side rotating shaft 160 in an indirect manner.

[0037] Specifically, in the present embodiment, please refer toFigure 1 And Figure 5 The power distribution encryption box 10 also includes a first gear 181, a second gear 182, and a fixed shaft 183. The first gear 181 is sleeved on the fixed shaft 183, and the fixed shaft 183 is rotatably arranged on the side wall of the accommodating shell 120. The second gear 182 is sleeved on the side rotating shaft 160 and is engaged with the first gear 181. One end of the telescopic part 151 away from the sliding block 152 is fixedly connected with the fixed shaft 183. In this way, when the telescopic part 151 rotates, the fixed shaft 183 can be driven to rotate, and then the first gear 181 is driven to rotate. Under the meshing transmission of the second gear 182 and the first gear 181, the side rotating shaft 160 can be driven to rotate together with the second gear 182, and finally the side plate 140 can be opened and closed to cover the second opening.

[0038] In order to improve the stability of the telescopic part 151 during the telescopic process, please refer to Figure 1 And Figures 5 to 7 In an embodiment, the telescopic part 151 includes a sleeve rod 1511 and a movable rod 1512. The rod wall of the sleeve rod 1511 is provided with a limiting groove 1513, and the limiting groove 1513 extends along the axial direction of the sleeve rod 1511. The movable rod 1512 is inserted into the sleeve rod 1511. The movable rod 1512 is provided with a limiting block 1514, and the limiting block 1514 is slidingly arranged in the limiting groove 1513. One end of the sleeve rod 1511 away from the movable rod 1512 is fixedly connected with the side rotating shaft 160, and one end of the movable rod 1512 away from the sleeve rod 1511 is rotatably connected with the sliding block 152. Through the limiting action of the limiting groove 1513, the movable rod 1512 can be prevented from being separated from the sleeve rod 1511 during movement, thereby affecting the normal use of the telescopic part 151.

[0039] Please refer to Figure 5 、 Figure 7 And Figure 8 In an embodiment, the sleeve rod 1511 is provided with a guide block 153. The side wall of the accommodating shell 120 is provided with a guide groove 122. The guide groove 122 is an arc structure, and the arc structure is curved towards the side rotating shaft 160. The guide block 153 is slidingly arranged in the guide groove 122. In this way, the telescopic part 151 can be supported during rotation, thereby improving the stability of the rotation of the telescopic part 151 and the side rotating shaft 160.

[0040] Specifically, in the present embodiment, as Figure 8As shown in the drawings, in the depth direction of the guide groove 122, the guide groove 122 is divided into a first groove body 1221 and a second groove body 1222 which are in communication with each other. The bottom wall of the second groove body 1222 is the bottom wall of the guide groove 122, and the second groove body 1222 cooperates with the first groove body 1221 to form a "T"-shaped groove. In other words, the width L2 of the second groove body 1222 is greater than the width L1 of the first groove body 1221. Correspondingly, the guide block 153 comprises a first block body 1531 and a second block body 1532 which are connected. The first block body 1531 is connected to the sleeve rod 1511, and the second block body 1532 cooperates with the first block body 1531 to form a "T"-shaped block. In other words, the width of the second block body 1532 is greater than the width of the first block body 1531. The first block body 1531 is slidingly arranged in the first groove body 1221, and the second block body 1532 is slidingly arranged in the second groove body 1222. In this way, the guide block 153 can be prevented from being separated from the guide groove 122 during sliding, so that the telescopic member 151 is stably supported.

[0041] In an embodiment, as shown in Figure 1 and Figure 6 , the guide portion 171 is a sliding groove. A U-shaped clamping groove 172 is formed in the fixed block 170, and two sliding grooves are respectively arranged on the two groove walls of the U-shaped clamping groove 172. The sliding block 152 is provided with two guide columns 1521 which are respectively inserted into the two sliding grooves. In this way, the stability of the sliding block 152 during movement can be improved.

[0042] In order to improve the stability of the control module 110 placed in the accommodating cavity 121, please refer to Figure 3 , Figure 4 and Figure 9 , in an embodiment, the power distribution encryption box 10 which is convenient to maintain further comprises a pressing block 191 and a pressing screw 192. The pressing screw 192 is threadedly connected to the wall of the accommodating shell 120, the pressing block 191 is arranged in the accommodating cavity 121 and is rotationally connected with the pressing screw 192, and the pressing block 191 is used to abut against the control module 110.

[0043] Specifically, as shown in Figure 9 , when the pressing screw 192 is threadedly connected to the wall of the accommodating shell 120, one end of the pressing screw 192 penetrating through the pressing block 191 is provided with a positioning block 193. Correspondingly, the control module 110 is provided with a positioning clamping groove 111, and under the action of the pressing screw 192, the pressing block 191 can be pressed on the control module 110, and the positioning block 193 is inserted into the positioning clamping groove 111. In this way, the control module 110 can be prevented from shaking in the accommodating cavity 121.

[0044] Specifically, in the present embodiment, as shown in Figure 1 , the top plate 130 comprises a first plate body 131 and a second plate body 132. As shown in Figures 1 to 4As shown, the accommodating shell 120 comprises a bottom shell 123, a first supporting shell 124, a second supporting shell 125 and a third supporting shell 126. The first supporting shell 124, the second supporting shell 125 and the third supporting shell 126 are connected in sequence and arranged around the bottom shell 123 to form an accommodating cavity 121 with a first opening and a second opening. For example, the bottom shell 123, the first supporting shell 124, the second supporting shell 125, the third supporting shell 126, the top plate 130 and the side plate 140 form a cuboid structure. The first plate body 131 is rotationally connected to the first supporting shell 124, the second plate body 132 is rotationally connected to the third supporting shell 126, and the first plate body 131 and the second plate body 132 are jointly arranged to cover the first opening. For example, the opening and closing manner of the first plate body 131 and the second plate body 132 is the same as that of a double-door refrigerator. In this way, the space required when the top plate 130 rotates can be reduced.

[0045] Further, the linkage mechanism 150 is provided with two linkage mechanisms 150, one of which is connected between the first plate body 131 and the side plate 140, and the other of which is connected between the second plate body 132 and the side plate 140. When the first plate body 131 and the second plate body 132 are simultaneously rotated, the side plate 140 can be simultaneously rotated under the action of the two linkage mechanisms 150.

[0046] In order to facilitate the rotation of the first plate body 131 and the second plate body 132, a handle 1322 is arranged on the first plate body 131 and the second plate body 132.

[0047] In an embodiment, a first through hole 1321 is arranged on the first plate body 131 and / or the second plate body 132, which is used to accommodate an indicator light on the control module 110. In addition, a second through hole 141 is arranged on the side plate 140, which is used to accommodate a plug interface or a mounting port on the control module 110.

[0048] Please refer to Figure 1 and Figure 2 In an embodiment, the power distribution encryption box 10 for facilitating maintenance further comprises a locking bolt 211 and a locking nut 212. The locking bolt 211 is arranged on the side plate 140. When the side plate 140 covers the second opening and the top plate 130 covers the first opening, the locking nut 212 is threadedly connected to the locking bolt 211 to press the top plate 130 against the side plate 140. By threadedly sleeving the locking nut 212 on the locking bolt 211 and pressing the top plate 130 against the side plate 140, the top plate 130 can be stably arranged to cover the first opening, and the side plate 140 can be stably arranged to cover the second opening.

[0049] Specifically, in the present embodiment, as Figure 10As shown, the first plate body 131 is provided with a clearance 1311 near one end of the second plate body 132, and the second plate body 132 is provided with a clearance 1311 near one end of the first plate body 131. When the side plate 140 is covered on the second opening, and the first plate body 131 and the second plate body 132 are covered on the first opening, the locking bolt 211 is accommodated in the clearance 1311, and the locking nut 211 is threadedly sleeved on the locking bolt 211 and abuts against the first plate body 131 and the second plate body 132.
