Description

Technical Field

[0001] The present invention relates to the technical field of electric meter boxes, and particularly to an electric meter box with an anti-stealing electricity alarm function. Background Art

[0002] Most traditional electric meter boxes only have basic functions for protecting electric meters, such as waterproofing, dustproofing, and anti-destruction, etc. However, the functions for monitoring and preventing electricity theft behaviors are relatively weak. Electricity theft behaviors usually manifest as users prying open the electric meter box, then privately connecting to the power line, tampering with the electric meter data, or bypassing the normal metering process of the electric meter through other illegal means. In order to prevent such problems from occurring, in recent years, electric meter boxes with anti-stealing electricity alarm functions have emerged as the times require.

[0003] In a Chinese patent (publication number: CN107290573B), an electric meter box with an anti-stealing electricity alarm function is disclosed, including: an electric meter box main body and a wireless alarm. A wireless alarm is provided on the upper right side of the electric meter box main body. Its characteristics are: it further includes an outgoing line chamber, an outgoing line pipe, a groove, an electric meter baffle, a wiring baffle, a box door, an electric meter, an electric meter wiring chamber, and a fixing seat. This patent can effectively ensure that the electricity in this electric meter box is disconnected after opening the box door through the door-opening power-off device, thus avoiding the possibility of stealing electricity by opening the door. In addition, the groove provided here can ensure that the box door cannot be closed when the wire passes through the electric meter box door, which further avoids the possibility of stealing electricity. Although the setting of opening the door to cut off the power in this patent avoids the possibility of stealing electricity by opening the door, this method will affect the normal electricity use of other users. At the same time, this patent and existing electric meter boxes are both conventionally arranged. After opening the box door, the internal electric meter can be directly wired, and the internal electric meter is easily stolen, and it is easy to bypass the door-opening power-off device, and the anti-stealing electricity protection is limited. Summary of the Invention

[0004] The purpose of the present invention is: to solve the above problems, the present invention provides an electric meter box with an anti-stealing electricity alarm function.

[0005] The present invention specifically adopts the following technical solutions to achieve the above purpose:

[0006] An electric meter box with an anti-stealing electricity alarm function includes a box body. A box door is hinged to the front of the box body. A guide groove is opened at the inner top of the box body. The inner wall of the guide groove near the box door side is provided with a first flipping tooth and a second flipping tooth. The inner wall on the other side of the guide groove is provided with a locking tooth. The locking tooth is correspondingly arranged with the first flipping tooth. The depth of the first flipping tooth is greater than the depth of the locking tooth.

[0007] An installation inner plate is inserted inside the box body. An electromagnet 1 is fixed at the top of the installation inner plate. A sliding shaft is arranged at the top of the installation inner plate. A flipping gear is slidably connected to the outer side of the sliding shaft. A top spring is arranged between the flipping gear and the electromagnet 1. A slider is rotatably installed at the top of the sliding shaft, and the slider is slidably connected in a guide groove;

[0008] An built-in lock assembly and an alarm switch are arranged on the inner wall on the left side of the box body. An alarm is fixedly installed at the top of the box body.

[0009] Further, the built-in lock assembly includes an inner lock block fixedly installed on the inner wall of the box body. A lock hole is opened inside the inner lock block. A sliding hole is opened at the inner top of the lock hole. An electromagnet 2 is fixedly installed inside the sliding hole. A lock core is slidably connected inside the sliding hole. A lock spring is arranged between the lock core and the electromagnet 2. The side of the lock core away from the box body is inclined. A lock catch is arranged on the inner side of the box door. The lock catch can be inserted into the lock hole, and the lock core can be inserted into the lock catch.

[0010] Further, an opening spring strip is arranged between the box door and the box body.

[0011] Further, a two-dimensional code is arranged on the outer side of the box door, and an access control controller is arranged inside the inner lock block.

[0012] Further, an installation back hole is opened on the back of the box body. A wire passing hole is penetrated through the bottom of the box body. Guide grooves are arranged at both the inner top and the inner bottom of the box body.

[0013] Further, sealing strips are arranged on the inner walls on both sides of the box body.

[0014] Further, the guide groove is composed of an inclined part and a vertical part. The first flipping tooth and the second flipping tooth are respectively arranged at the left end and the right end of the inclined part.

[0015] Further, the axis of the sliding shaft is close to the right end of the installation inner plate.

[0016] Further, a wire groove opening is opened at the bottom of the installation inner plate.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. In the present invention, by moving and installing the inner plate, the installed inner plate drives the slider to slide in the guide groove. And through the arrangement of the first flipping teeth and the second flipping teeth on the inner wall of the guide groove, the flipping of the installed inner plate can be realized within a limited space, so that the electric meter is turned towards the inside of the box body. When the box door is illegally opened, the flipping gear is simultaneously engaged with the first flipping teeth and the locking teeth, and the installed inner plate cannot rotate or slide and is locked. The installed inner plate protects the electric meter in the electric meter box, eliminating the possibility of electricity theft from the source and not affecting the normal use of other users. At the same time, when the box door is illegally opened, the alarm switch is triggered, and the alarm emits an alarm sound, which brings a certain deterrence to the electricity thief, and the anti-electricity-theft effect is good.

[0019] 2. After the electric meter box of the present invention is closed, the installed inner plate can play a role in plugging and isolating, ensuring that external dust and rainwater are not easily introduced into the box body to contaminate the internal electrical components.

[0020] 3. When the present invention is opened normally, the electromagnet is energized to drive the flipping gear to slide downward. When the flipping gear is engaged with the first flipping teeth, at this time, when the installed inner plate is pushed to slide along the guide groove, under the action of the first flipping teeth, the flipping gear drives the installed inner plate to rotate, and the installed inner plate drives the electric meter to rotate to the outside of the electric meter box. During maintenance, there is no need to reach into the box body for operation, and the detection is convenient. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0030] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] Embodiment 1, as Figures 1 - 8 shown, an electricity meter box with an anti-stealing electricity alarm function includes a box body 1, a box door 2 is hinged to the front of the box body 1, a guide groove 12 is opened at the inner top of the box body 1, a first flipping tooth 121 and a second flipping tooth 122 are arranged on the inner wall of the guide groove 12 close to the box door 2, a locking tooth 123 is arranged on the inner wall of the other side of the guide groove 12, the locking tooth 123 is arranged corresponding to the first flipping tooth 121, and the depth of the first flipping tooth 121 is greater than the depth of the locking tooth 123;

[0032] An inner mounting plate 3 is inserted into the inside of the box body 1, an electromagnet I 32 is fixed to the top of the inner mounting plate 3, a sliding shaft 33 is arranged on the top of the inner mounting plate 3, a flipping gear 34 is slidably connected to the outside of the sliding shaft 33, a top spring 35 is arranged between the flipping gear 34 and the electromagnet I 32, a slider 36 is rotatably mounted on the top of the sliding shaft 33, and the slider 36 is slidably connected in the guide groove 12;

[0033] An internal lock assembly and an alarm switch 5 are arranged on the inner wall of the left side of the box body 1, and an alarm 6 is fixedly mounted on the top of the box body 1.

[0034] Furthermore, a mounting back hole 11 is opened on the back of the box body 1, a wire passing hole 13 penetrates through the bottom of the box body 1, and guide grooves 12 are arranged on both the inner top and inner bottom of the box body 1.

[0035] The present invention adopts the setting of an internal lock assembly, so that the lock is located inside the box body 1 and is not easily discovered and damaged. When opening the door normally, the box door 2 opens normally, the alarm switch 5 will not be triggered, and the electromagnet 32 is energized. The electromagnet 32 drives the flipping gear 34 to slide downward, and the flipping gear 34 disengages from the locking tooth 123. At this time, the flipping gear 34 only meshes with the first flipping tooth 121, and the installation inner plate 3 is pushed inward. The installation inner plate 3 drives the slider 36 to slide along the guide groove 12 into the box body 1. At this time, the flipping gear 34 rotates under the action of the first flipping tooth 121, and the flipping gear 34 drives the installation inner plate 3 to rotate. The installation inner plate 3 rotates 90 degrees, and the installation inner plate 3 drives the internal electric meter to rotate to the outside of the box body 1. At this time, it is convenient to wire and repair the electric meter, and it is more convenient for normal use. And when it rains outside, the slider 36 continues to slide along the guide groove 12 and slides into the box body 1. The flipping gear 34 disengages from the first flipping tooth 121. When the flipping gear 34 meshes with the second flipping tooth 122, the second flipping tooth 122 drives the flipping gear 34 to rotate, and the flipping gear 34 drives the installation inner plate 3 to rotate to the horizontal, and the electric meter faces outward, which is convenient for wiring and repair in rainy days.

[0036] After the wiring and repair are completed, the slider 36 slides along the guide groove 12 to reset. At this time, the side of the installation inner plate 3 where the electric meter is installed faces the inside of the box body 1, and the installation inner plate 3 acts as a protection. Then the box door 2 is closed to form a double protection. Through this structural design, the overall sealing performance of the box body 1 can be improved.

[0037] When the box door 2 is opened abnormally, the alarm switch 5 is triggered. It should be noted that when closing the door, the box door 2 presses on the alarm switch 5. When opening the door normally, the alarm switch 5 will disconnect from the alarm 6. Therefore, when opening abnormally, the box door 2 is far from the alarm switch 5, and the alarm switch 5 will energize the alarm 6. The alarm 6 emits an alarm, which brings a certain deterrent to the electricity thieves. At the same time, the electromagnet 32 is not energized, and the flipping gear 34 meshes with both the first flipping tooth 121 and the locking tooth 123 at the same time. The flipping gear 34 cannot rotate and move. Therefore, the installation inner plate 3 cannot rotate and move, making it impossible for the electricity thieves to wire the internal electric meter, eliminating the possibility of electricity theft from the source, and not affecting the normal use of other users. The anti-electricity-theft effect is good.

[0038] Embodiment 2, on the basis of the above embodiment, further includes that the internal lock assembly includes an inner lock block 4 fixedly installed on the inner wall of the box body 1. A lock hole 41 is opened inside the inner lock block 4. A sliding hole is opened at the inner top of the lock hole 41. An electromagnet 42 is fixedly installed inside the sliding hole. A lock core 43 is slidably connected inside the sliding hole. A lock spring 44 is arranged between the lock core 43 and the electromagnet 42. The side of the lock core 43 away from the box body 1 is inclined. A lock catch 21 is arranged on the inner side of the box door 2. The lock catch 21 can be inserted into the lock hole 41, and the lock core 43 can be inserted into the lock catch 21.

[0039] Further, an opening spring strip 7 is provided between the box door 2 and the box body 1.

[0040] When opening the door, the second electromagnet 42 is energized, the second electromagnet 42 drives the lock core 43 to slide upward, the lock core 43 disengages from the lock catch 21, and the opening spring strip 7 drives the box door 2 to open automatically; when closing the door, the box door 2 drives the lock catch 21 to insert into the lock hole 41, and the lock catch 21 first pushes the lock core 43 upward through the inclined surface of the lock core 43, and then when the locking position of the lock catch 21 moves to the position of the lock core 43, the lock core 43 is inserted into the locking position of the lock catch 21 to complete automatic door locking. The door locking structure is simple and the built-in door locking effect is good.

[0041] Embodiment 3, on the basis of the above embodiment, further includes a two-dimensional code provided on the outer side of the box door 2, and an access control controller is provided inside the inner lock block 4.

[0042] The staff scans the two-dimensional code with a mobile phone and transmits it to the access control controller through the Weigang protocol. At this time, the access control controller will judge whether the person is authorized by comparing the previously entered personnel information. If the matching is successful, the controller will execute the unlocking instruction to open the door, otherwise it will be the opposite, and the unlocking is convenient.

[0043] Embodiment 4, on the basis of the above embodiment, further includes sealing strips 14 provided on the inner walls on both sides of the box body 1. Through the arrangement of the sealing strips 14, when the electric surface of the inner plate 3 is facing the inside of the box body 1, the sealing strips 14 are pressed against the edge of the inner plate 3 for sealing, and the sealing effect is good.

[0044] Embodiment 5, on the basis of the above embodiment, further includes that the guide groove 12 is composed of an inclined part and a vertical part, and the first flipping tooth 121 and the second flipping tooth 122 are respectively arranged at the left end and the right end of the inclined part.

[0045] Further, the axis of the sliding shaft 33 is close to the right end of the inner plate 3 for installation. This direction is as shown in the attached Figure 8 figure, that is, when the meter installation surface of the inner plate 3 for installation faces outward, the axis of the sliding shaft 33 is close to the right end of the inner plate 3 for installation.

[0046] Through the arrangement of the inclined part, when the inner plate 3 for installation is pushed into the box body 1, the inner plate 3 for installation will move to the right while rotating, which can better realize the movement and flipping of the inner plate 3 for installation. And through the setting that the axis of the sliding shaft 33 is close to the right end of the inner plate 3 for installation, there is no need to set a deeper space in the box body 1. The main flipping space of the inner plate 3 for installation utilizes the space outside the box body 1, and the flipping effect is good, and the structure of the box body 1 is compact.

[0047] Embodiment Six. On the basis of the above embodiments, it further includes that a wire groove opening 31 is formed at the bottom of the installation inner plate 3. When the installation inner plate 3 is turned over and its bottom rotates to the position of the guide groove 12, there is a wire passing space. However, the connecting wire is still likely to get stuck in the middle of the installation inner plate 3. Therefore, with the setting of the wire groove opening 31, the situation of squeezing the connecting wire will not occur.

[0048] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
