Description

Technical Field

[0001] The invention belongs to the technical field of meter boxes, and in particular relates to a meter box with an anti-theft alarm function. Background Art

[0002] In the fields of public facilities such as electricity, communications, and gas, meter boxes are important equipment containers used to install and protect various metering instruments (such as electricity meters, water meters, and gas meters). Their safety and anti-theft performance are directly related to the accuracy of data and the continuity of services. Although traditional meter boxes have basic anti-theft functions to a certain extent, their protection capabilities are insufficient in the face of increasingly complex and professional theft methods.

[0003] First of all, most of the existing anti-theft meter boxes rely on a single physical lock (such as mechanical lock, electronic lock) to achieve the anti-theft function. Although these locks increase the difficulty of opening to a certain extent, once the cracking method is mastered, its protection effect will be greatly reduced.

[0004] Secondly, conventional physical destruction methods such as prying locks and drilling holes can often break through the protection of traditional meter boxes in a short period of time, not only causing property losses, but also seriously affecting the normal operation of public facilities and the legitimate rights and interests of users.

[0005] Finally, although some meter boxes have integrated alarm systems, they are often difficult to effectively play an early warning role due to simple design, delayed response or susceptibility to interference. More importantly, when there is a power outage, many protection mechanisms that rely on power will fail, which undoubtedly increases the difficulty of anti-theft. Summary of the invention

DETAILED DESCRIPTION

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0025] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0026] Please see attached Figures 1 to 15 As shown, this embodiment provides a metering box with an anti-theft alarm function, including a box assembly 10, the box assembly 10 includes a main body assembly 11, a trap assembly 12 is arranged on the front of the main body assembly 11, and an alarm assembly 13 is arranged in the inner cavity of the main body assembly 11; The anti-theft component 20 includes a password lock 1 21 arranged on the left side of the main component 11, a password lock 2 22 is arranged on the top of the inner cavity of the main component 11, a linkage component 23 is arranged on the top of the inner cavity of the main component 11, and a power-off protection component 24 is arranged on the left side of the inner cavity of the main component 11; Among them, the trap component 12 forges the opening method of the main component 11, and when the trap component 12 is triggered, an alarm is sounded through the alarm component 13; When opening, after the correct input of the password lock 1 21, the top of the password lock 2 22 is opened; after the password lock 2 22 is successfully opened, the linkage component 23 drives the main component 11 to open; The power-off protection component 24 is used to provide protection when the main component 11 is powered off.

[0027] In this embodiment, in daily use, the trap component 12 can effectively confuse people and make them mistakenly believe that the meter box can be opened by simple operation. When they try to open the trap component 12, the alarm component 13 will be activated immediately, sound an alarm and record and alarm, and the linkage component 23 will lock the main component 11 to prevent further illegal operations. The design of the password lock 1 21 and the password lock 2 22 makes it difficult to operate correctly in a short time even if the password is stolen, because they need to enter the password in a specific order and way, which increases the complexity of the operation and improves security. The password lock 1 21 enters the password by pressing a button, while the password lock 2 22 needs to pass through a specific slot and pull up to trigger the linkage component 23. This design makes it difficult to successfully open the meter box without correct operation even if the password is leaked. The power-off protection component 24 automatically drops the blocking component in the case of power failure, ensuring that the meter box can be effectively protected even when the power supply is interrupted. The coordinated work of these components greatly improves the safety performance of the meter box and effectively prevents theft and vandalism.

[0028] Next, please refer to Figures 1 to 5 The main body component 11 includes a box 111, a box door 112 is hinged at the bottom of the front of the box 111, and push rods 113 are fixedly connected to the left and right sides of the inner cavity of the box 111, and the outer ends of the push rods 113 are in contact with the rear side of the box door 112.

[0029] The trap assembly 12 includes a handle 121 movably sleeved on the front side of the door 112, a first spring 122 is fixedly connected to the inner cavity of the door 112, a rear end of the first spring 122 is fixedly connected to the rear end of the handle 121, a button 123 is fixedly installed in the inner cavity of the door 112, the front side of the rear end of the handle 121 contacts the surface of the button 123, a trap keyhole 124 is installed on the right side of the front side of the door 112, and a button 2 125 is fixedly installed inside the trap keyhole 124.

[0030] The alarm component 13 includes speakers 131 fixedly installed on the left and right sides of the inner cavity of the box 111, a processor 132 fixedly installed on the top of the inner cavity of the box 111, a camera 133 fixedly installed on the top of the inner cavity of the box 111, and the camera 133 is electrically connected to the processor 132.

[0031] It should be noted that the portion where the box door 112 is connected to the box 111 is a hidden hinge, thereby improving the hiding effect and enhancing the secrecy and authenticity of the trap assembly 12.

[0032] The processor 132 has a built-in battery and an alarm device (not shown in the figure) to facilitate alarming and to provide protection and recording for a certain period of time in the event of a power outage, thereby improving safety.

[0033] In this embodiment, in daily use, the handle 121 and the trap keyhole 124 can be used to forge the opening method of the box door 112, so that when it is invaded, once the handle 121 is pulled, the button 123 will be triggered, and when the lock is pried, the trigger button 2 125 will be squeezed, so that the processor 132 receives a signal, and the sounder 131 immediately sounds an alarm, and the camera 133 starts recording. If the door is forced to break in, the camera 133 can be used to take pictures and record videos. The processor 132 records the image and time information of the invasion, and sends an alarm through the built-in alarm device. This design can not only detect and record illegal intrusions in a timely manner, but also deter through dual alarms of sound and vision, thereby effectively protecting the equipment and data security in the metering box.

[0034] Next, please refer to Figures 6 to 12 The combination lock 21 includes a shell 211 fixedly connected to the left side of the box 111, a combination plate 212 is fixedly installed in the inner cavity of the shell 211, a limit rod 213 is fixedly connected to the inner cavity of the shell 211, a pressing block 214 is movably sleeved on the outer ring of the limit rod 213, a second spring 215 is fixedly connected to the middle part of the inner cavity of the pressing block 214, and the rear end of the second spring 215 is fixedly connected to the inner cavity of the limit rod 213.

[0035] The combination lock 22 includes a lock body 221 fixedly connected to the top of the rear side of the box door 112, the inner cavity of the lock body 221 is provided with multiple layers of slots 222, and buttons 3 223 are fixedly installed on the top of the inner cavity of the slots 222. The lock body 221 is provided with through grooves 224 on the slots 222 of each layer, the inner cavity of the lock body 221 is slidably connected with a lifting rod 225, the bottom outer ring of the lifting rod 225 is fixedly connected with an extrusion rod 226, and the top outer ring of the lifting rod 225 is fixedly connected with an indicator needle 227, the top of the box 111 is slidably connected with a cover plate 228 at a position above the lifting rod 225, the rear side of the cover plate 228 is fixedly connected with an electric push rod 229, and the rear end of the electric push rod 229 is fixedly installed on the top of the inner cavity of the box 111, and the top of the box 111 is provided with an annular groove in the area of ​​the outer ring of the lifting rod 225, and an indicator bar 2210 is arranged in the groove, and the bottom surface of the indicator needle 227 is in contact with and connected above the indicator bar 2210.

[0036] The linkage assembly 23 includes an unlocking key 231 fixedly installed on the top of the inner cavity of the box 111, electronic locks 232 are fixedly installed on both sides of the top of the inner cavity of the box 111, and lock holes 233 are fixedly installed on the top of the rear side of the box door 112. The bottom of the electronic lock 232 is movably inserted into the lock hole 233.

[0037] The outer ring of the lifting rod 225 is evenly provided with scale bars, and the spacing of the scale bars is the same as the height spacing of each layer of the slots 222, so as to remind the operator to rotate the lifting rod 225 in time.

[0038] It should be noted that the password board 212 is input by pressing buttons. Pressing any one button inputs 1, pressing any two buttons inputs 2, and so on. The user inputs the password by pressing different numbers of buttons. An electronic recognition system is provided inside the password board 212, which can recognize the order and duration of pressing, ensuring that only the correct password input can successfully unlock the door.

[0039] The inner circle of the lock body 221 is provided with four layers, each layer is provided with six groups of slots 222, and each group of slots 222 corresponds to the position of the indicator bar 2210, and among the six groups of slots 222 in each layer, one group is a through slot 224, and button three 223 is not provided in the through slot 224. The user raises the lifting rod 225 to different heights and adjusts the correct direction of the squeezing rod 226 before rising, so that the lifting rod 225 can rise correctly until it touches the unlocking key 231 to achieve successful unlocking. Once the squeezing rod 226 is in the wrong direction, it will touch button three 223 to trigger an alarm.

[0040] In this embodiment, when unlocking, the pressing block 214 in the housing 211 is pressed, and the password plate 212 will identify the input password according to the order and duration of pressing. If the password is correct, the electric push rod 229 will pull the cover plate 228 into the box 111, exposing the top of the lifting rod 225. If the password is wrong, the alarm is triggered immediately. Then, according to the indication of the indicator needle 227 and the indicator bar 2210, the lifting rod 225 and the squeeze rod 226 are adjusted to the correct direction, and the lifting rod 225 is pulled up until the lifting rod 225 is completely separated from the lock body 221, and the squeeze rod 226 touches the unlocking key 231, so that the electronic lock 232 is retracted and separated from the lock hole 233, and the door 112 is unlocked. The arrangement of the multi-layer slot 222 and the button three 223 in the lock body 221 increases the complexity of unlocking and effectively prevents illegal unlocking attempts. In addition, the scale bar on the lifting rod 225 of the combination lock 22 and the indicator bar 2210 in the annular groove provide the user with intuitive unlocking guidance, ensuring the convenience of operation.

[0041] Next, please refer to Figures 13 to 15 The power-off protection component 24 includes a clamping strip 241 fixedly connected to the left side of the inner cavity of the box door 112, a rotating rod 242 is provided on the left side of the inner cavity of the box 111, a baffle 243 is slidably connected to the inner cavity of the rotating rod 242, the front top of the baffle 243 is clamped on the rear side of the clamping strip 241, and a magnetic suction plate 244 is installed on the top of the baffle 243, an electromagnetic plate 245 is fixedly connected to the left side of the inner cavity of the box 111, a lock core 246 is fixedly installed on the left side of the box 111, the right end rotating part of the lock core 246 is fixedly connected to the rotating rod 242, and a baffle 247 is slidably connected to the left side of the box 111.

[0042] An arc-shaped strip is disposed on the top of the blocking strip 243 , and when the blocking strip 243 rotates to the bottom of the inner cavity of the rotating rod 242 , it cannot be parallel to the clamping strip 241 and deviates downward.

[0043] It should be noted that when the blocking bar 243 rotates to the bottom of the inner cavity of the rotating rod 242, it is not in a vertical state, but tilted downward, so that after the electromagnetic plate 245 loses its magnetism, the blocking bar 243 will slide downward due to the effect of gravity.

[0044] In this embodiment, under normal conditions, the electromagnetic plate 245 attracts the magnetic plate 244 through magnetic force, so that the blocking bar 243 is always above the card strip 241. When the meter box encounters a power outage, the electromagnetic plate 245 loses its magnetism, and the blocking bar 243 slides down due to gravity and gets stuck in front of the card strip 241, making the box door 112 unable to open, forming a physical barrier. Only by inserting an adapted key into the lock cylinder 246 can the rotating rod 242 and the blocking bar 243 be driven to rotate upward, so that the blocking bar 243 is separated from the card strip 241, and the box door 112 can be opened. This design not only improves the safety of the meter box, but also ensures that the equipment and data in the meter box can be effectively protected in emergency situations such as power outages.

[0045] The working principle of the present invention is as follows: in daily use, the handle 121 and the trap keyhole 124 can be used to forge the opening method of the box door 112, so that when it is invaded, if the handle 121 is pulled, the button 123 will be triggered, and when the lock is pried, the trigger button 2 125 will be squeezed, so that the processor 132 receives a signal to alarm, and the sounder 131 immediately emits an alarm sound. If the door is forced to break, the camera 133 can be used to take pictures and record videos. When unlocking, the pressing block 214 in the shell 211 is pressed, and the password board 212 will recognize the input password according to the order and duration of pressing. If the password is correct, the electric push rod 229 will pull the cover plate 228 into the box 111, exposing the top of the lifting rod 225. If the password is wrong, the alarm is triggered immediately. Then, according to the indication of the indicator needle 227 and the indicator bar 2210, adjust the lifting rod 225 and the squeezing rod 226 to the correct direction, pull the lifting rod 225 up, until the lifting rod 225 is completely separated from the lock body 221, and the squeezing rod 226 touches the unlocking key 231, so that the electronic lock 232 is retracted and separated from the lock hole 233, and the box door 112 is unlocked. When the metering box encounters a power outage, the electromagnetic plate 245 loses its magnetism, and the blocking bar 243 slides down due to gravity and gets stuck in front of the card bar 241, so that the box door 112 cannot be opened, forming a physical barrier. Only by inserting the adapted key into the lock core 246 can the rotating rod 242 and the blocking bar 243 be driven to rotate upward, so that the blocking bar 243 is separated from the card bar 241, and the box door 112 can be opened.

[0046] The above are only preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principles of the present invention, and these improvements and modifications should also be considered as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to conventional means in the art unless otherwise specified and limited.
