DETAILED DESCRIPTION
[0029] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0031] like Figure 1-Figure 8 A high protection level electric energy metering box shown in the figure comprises a box body 1, a protection frame 101 is fixedly connected to one side of the box body 1, a partition 103 is fixedly connected to the inner wall of the box body 1, two box doors 102 are hingedly connected to the inner side of the protection frame 101, and a protection structure 2 is provided on the surface of the box door 102 and the partition 103;
[0032] The protection structure 2 includes two grooves 201 opened on the surface of the partition 103 and symmetrically distributed. The inner wall of the groove 201 is fixedly connected to the limiting column 202. The surface of the box door 102 is provided with a limiting component 21 for cooperating with the limiting column 202 to limit the position of the box door 102. The inside of the box door 102 is provided with an anti-theft component 22. A controller is provided on one side of the box body 1, and an audible and visual alarm is provided on the surface of the controller.
[0033] Among them, the limiting component 21 includes a slide plate 2101 arranged on the inner wall of the box door 102, a connecting groove is opened on one side of the box door 102, the slide plate 2101 is slidingly connected to the inner wall of the connecting groove, the surface of the slide plate 2101 is rotatably connected to a rotating plate 2110, the interior of the box door 102 is rotatably connected to a first lock body 2102, and the surface of the rotating plate 2110 is opened with a through groove for the key to pass through.
[0034] The first lock body 2102 is provided with a matching key, and the first lock body 2102 can be driven to rotate by inserting the key into the lock hole of the first lock body 2102 .
[0035] like Figure 1-Figure 8 As shown, a connecting plate 2104 is fixedly connected to the other side of the box door 102, the other end of the connecting plate 2104 extends to the inside of the groove 201, and a block 2106 is provided on the top of the connecting plate 2104, which is located on the side of the limiting column 202 away from the box door 102, and a slope is provided on the side of the block 2106 away from the limiting column 202.
[0036] One end of the first lock body 2102 away from the slide plate 2101 is fixedly connected to the connecting shaft 2103, and the other end of the connecting shaft 2103 is fixedly connected to the connecting rod 2105 rotatably connected to the inner wall of the connecting plate 2104. The surface of the connecting rod 2105 is fixedly connected to the connecting rope 2107, and the other end of the connecting rope 2107 is fixedly connected to the bottom of the block 2106.
[0037] A sliding plate 2108 slidably connected to the inner wall of the connecting plate 2104 is fixedly connected to the surface of the block 2106 , and a first spring 2109 is fixedly connected between the bottom of the sliding plate 2108 and the inner wall of the connecting plate 2104 .
[0038] By inserting the key into the interior of the first lock body 2102, the first lock body 2102 can be driven to rotate, thereby driving the connecting shaft 2103 and the connecting rod 2105 connected thereto to rotate synchronously. In this process, the connecting rope 2107 can be rolled up, and the block 2106 can be driven to retract into the interior of the connecting plate 2104 by rolling up the connecting rope 2107. In this process, the sliding plate 2108 can be driven to squeeze the first spring 2109. At this time, the box door 102 can be opened without being blocked by the block 2106 by the limit column 202 and affecting the normal opening. When closing, the first lock body 2102 is twisted to reset, thereby driving the connecting shaft 2103 and the connecting rod 2105 to rotate synchronously. The rod 2105 rotates to reset, and during this process the connecting rope 2107 can be unwound, thereby driving the sliding plate 2108 and the block 2106 to reset under the action of the first spring 2109. During the closing process, the connecting plate 2104 can be inserted into the interior of the groove 201, and the limiting column 202 can squeeze the inclined surface of the block 2106 to shrink it to the interior of the connecting plate 2104, which will not affect the closing of the door 102, until the block 2106 passes through the limiting column 202 as a whole and can be driven to reset under the action of the first spring 2109. At this time, the block 2106 can be blocked by the limiting column 202 so that it cannot open the door 102 in the reverse direction.
[0039] like Figure 1-Figure 8As shown, the anti-theft component 22 includes a second lock body 2201 rotatably connected to the inner wall of the door 102 and located below the first lock body 2102. The second lock body 2201 is coaxially arranged with the rotating plate 2110. The end of the second lock body 2201 away from the rotating plate 2110 is fixedly connected to a mounting shaft 2202, and a gear 2203 is fixedly connected to the surface of the mounting shaft 2202.
[0040] The anti-theft component 22 also includes a pull block 2204 arranged on the surface of the skateboard 2101, and a rotating shaft 2205 is fixedly connected to one side of the pull block 2204. An installation cavity 2207 is opened inside the skateboard 2101, and the other end of the rotating shaft 2205 is rotatably connected to the inner wall of the installation cavity 2207. A spring 2206 is fixedly connected to the surface of the rotating shaft 2205, and the other end of the spring 2206 is fixedly connected to the inner wall of the skateboard 2101.
[0041] The surface of the rotating shaft 2205 is fixedly connected to a cam 2208 located inside the installation cavity 2207, and the inner wall of the installation cavity 2207 is slidably connected to a trigger plate 2209. One side of the trigger plate 2209 is in contact with the surface of the cam 2208, and the other side of the trigger plate 2209 is fixedly connected to a limiting rod 2210. A limiting groove is provided inside the box door 102, and the other end of the limiting rod 2210 extends to the inside of the limiting groove.
[0042] A second spring 2211 is fixedly connected to the surface of the trigger plate 2209 , and the other end of the second spring 2211 is fixedly connected to the inner wall of the installation cavity 2207 .
[0043] Under normal conditions, the slide plate 2101 will block the first lock body 2102. The key will be directly inserted into the second lock body 2201 by passing through the through slot of the rotating plate 2110. At this time, rotating the second lock body 2201 can drive the installation shaft 2202 to rotate without unlocking the box door 102. The second lock body 2201 and the rotating plate 2110 can prevent malicious actors from opening the first lock body 2102 and directly opening the box door 102 to adjust or even damage the metering equipment inside the box 1, thereby improving the safety protection performance of the electric energy metering box.
[0044] Under normal circumstances, the setting of the mainspring 2206 can maintain the position of the rotating shaft 2205 and the pull block 2204, and can ensure that the cam 2208 pushes the limiting rod 2210 to insert into the limiting groove, thereby limiting the position of the slide plate 2101, avoiding the situation where the slide plate 2101 can be directly pulled to move out of the position of the first lock body 2102.
[0045] When it is necessary to open, the pull block 2204 can be rotated to tighten the spring 2206 and drive the rotating shaft 2205 to rotate, and at this time, the cam 2208 can be driven to rotate inside the installation cavity 2207. In this process, the trigger plate 2209 can be driven to be close to the surface of the cam 2208 under the action of the second spring 2211, so that during the rotation of the cam 2208, the trigger plate 2209 can gradually move toward the direction of the rotating shaft 2205, thereby driving the limiting rod 2210 to separate from the limiting groove. At this time, the slide plate 2101 can be moved downward to expose the first lock body 2102 to facilitate unlocking the box door 102. This setting method can prevent malicious actors.
[0046] like Figure 1-Figure 8 As shown, the anti-theft component 22 also includes an auxiliary rod 2212 slidably connected to the inner wall of the box door 102, a rack 2213 is fixedly connected to the surface of the auxiliary rod 2212, the rack 2213 is meshingly connected to the gear 2203, a mounting plate 2214 is fixedly connected to one side of the auxiliary rod 2212, a fixing plate 2216 is fixedly connected to the inner wall of the box door 102, and a third spring 2215 is fixedly connected between the fixing plate 2216 and the mounting plate 2214.
[0047] A locking groove 2217 corresponding to the auxiliary rod 2212 is formed on the inner side of the protection frame 101 , and a pressure sensor is disposed inside the locking groove 2217 .
[0048] When a malicious actor inserts the key into the second lock body 2201 and rotates it, the gear 2203 can be driven to rotate synchronously, thereby driving the rack 2213 to move upward so that the auxiliary rod 2212 passes through the box door 102 and is inserted into the lock slot 2217. At this time, the auxiliary rod 2212 can apply pressure to the pressure sensor, so that the pressure sensor transmits the signal to the controller after detecting the pressure, and the controller activates the sound and light alarm to sound an alarm. The third spring 2215 is set to keep the auxiliary rod 2212 located inside the box door 102 under normal circumstances.
[0049] Working principle: when it is necessary to open, the pull block 2204 can be rotated to tighten the mainspring 2206 and drive the rotating shaft 2205 to rotate, at which time the cam 2208 can be driven to rotate inside the mounting cavity 2207. In this process, the trigger plate 2209 can be driven to be close to the surface of the cam 2208 under the action of the second spring 2211, so that during the rotation of the cam 2208, the trigger plate 2209 can be gradually moved in the direction of the rotating shaft 2205, thereby driving the limiting rod 2210 to separate from the limiting groove, and at this time the slide plate 2101 can be moved downward to expose the first lock body 2102 to unlock the door 102, and the first lock body 2102 can be driven to rotate by inserting the key into the first lock body 2102, thereby driving the connecting shaft 2103 and the connecting rod 2105 connected thereto to rotate synchronously, and in this process the connecting rope 2107 can be rolled up, and the block 2106 can be driven to retract to the inside of the connecting plate 2104 by rolling up the connecting rope 2107, and in this process the sliding plate 2108 can be driven to squeeze the first spring 2107. The key is directly inserted into the second lock body 2201 by passing the key through the through slot of the rotating plate 2110. At this time, rotating the second lock body 2201 can drive the installation shaft 2202 to rotate, and will not unlock the door 102. The second lock body 2201 and the rotating plate 2110 can prevent malicious actors from opening the first lock body 2102 and directly opening the door 102 to adjust or even damage the metering equipment inside the box body 1, thereby improving the safety protection performance of the electric energy metering box. During the rotation of the installation shaft 2202, the rack 2213 can be driven to move upward, so that the auxiliary rod 2212 passes through the door 102 and is inserted into the lock slot 2217. At this time, the auxiliary rod 2212 can apply pressure to the pressure sensor, so that the pressure sensor transmits the signal to the controller after detecting the pressure, and the controller activates the sound and light alarm to sound an alarm.
