Description

Technical Field

[0001] This invention relates to the field of electricity metering box technology, and in particular to a box-type electricity metering box based on a smart grid. Background Technology

[0002] A modular power metering box is a device used in power engineering to accurately measure the power consumption of designated electrical equipment, thereby facilitating statistical work by users and power workers. Existing modular power metering boxes are fixedly installed in a designated location and then connected to the power line to measure power consumption; however, this design is not conducive to combining multiple modular power metering boxes.

[0003] A modular power metering box, with announcement number CN119834092A, includes a box body, mounting frame, top plate, base, and legs. At least two vertical longitudinal support plates are installed on both sides of the mounting frame. Two main quick-assembly beams and two auxiliary quick-assembly beams are horizontally installed on the outer sides of the longitudinal support plates on both sides of the box body. When two adjacent boxes are joined together, the main quick-assembly beam on one side of the box body and the auxiliary quick-assembly beam on the other side fit together vertically. The fitting sides of the main and auxiliary quick-assembly beams are respectively provided with a first insertion hole and an elastic top post on the same straight line. This technical solution greatly simplifies the assembly process of multiple boxes by using the elastic top posts on the main and auxiliary quick-assembly beams in conjunction with the first insertion holes. Furthermore, the large gap between the longitudinal support plates facilitates the connection of electrical components within the assembled two boxes.

[0004] The above technical solution can achieve box-type connection, but during normal operation, the existing metering box cannot monitor the operation of the components inside the metering box in real time, so it needs to be improved. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a smart grid-based box-type power metering box.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A smart grid-based box-type power metering box includes a metering cabinet assembly, the upper end of which is equipped with a heat dissipation and ventilation device. A door panel is hinged to one side of the metering cabinet assembly; a circulation mechanism is installed on the door panel, a sliding frame is provided on the circulation mechanism, a lead screw is rotatably sleeved on the sliding frame, the lead screw and the sliding frame are arranged parallel to each other, a reciprocating mechanism is installed on one side of the lead screw, the reciprocating mechanism is connected to the door panel, a lead screw nut is screwed onto the lead screw, a mounting plate is fixed to one side of the lead screw nut, the mounting plate is slidably installed on the sliding frame, clamping plates are installed at both the upper and lower ends of the mounting plate, the two clamping plates together clamp the monitoring assembly, the lower clamping plate is fixedly connected to the mounting plate, and a reset mechanism is provided on the upper clamping plate, the reset mechanism is connected to the mounting plate.

[0007] Compared with existing technologies, this invention achieves precise vertical vibration reduction through the coordinated operation of the main support chain of "fixed tube-adaptive mechanism-fixed seat" and the parallel damping chain of "moving component-swing arm-shoulder sleeve-first damper". Multiple sets of second dampers evenly distributed on the fixed plate form a ring-shaped multi-directional damping layout, which, together with the displacement movement of the sliding component along the slide rail, achieves comprehensive horizontal buffering. The L-shaped moving component integrates the vertical swing arm linkage and the horizontal slide arm linkage, enabling the horizontal and vertical forces to be coupled, transmitted, and buffered collaboratively through the same component, significantly improving overall vibration reduction efficiency. The spring automatically returns to its original length after vibration reduction, pushing the sliding component back to its position, allowing for continuous and effective operation without manual intervention. Furthermore, the metering cabinet assembly and the fixed seat are detachably connected, facilitating quick disassembly and maintenance, and significantly reducing operation and maintenance costs. The cyclic monitoring mechanism uses a motor assembly to drive a transmission belt that causes the sliding frame to rise and fall in a cyclic manner. The gears and racks work together to make the lead screw rotate in both directions, causing the mounting plate and monitoring components to move back and forth inside the cabinet. This enables accurate detection of multiple locations within the metering cabinet, overcoming the technical shortcomings of traditional metering boxes, such as large blind spots and inconvenient wiring between adjacent boxes.

[0008] Preferably, the circulation mechanism includes a motor assembly installed at the lower end of the door panel. A transmission wheel is installed at the end of the output shaft of the motor assembly and on one side of the upper end of the door panel. The two transmission wheels are connected by a transmission belt. A first sliding member is rotatably connected to the transmission belt. The sliding frame is slidably installed in the first sliding member and on the door panel.

[0009] Furthermore, it can provide power for the movement of monitoring components, which helps to achieve cyclical movement and improve the accuracy of detection.

[0010] Preferably, the reciprocating mechanism includes a gear fixed to one end of the lead screw, a rack meshing with the gear, the rack being fixed to one side of the door panel, and the rack and the lead screw being arranged perpendicularly.

[0011] Furthermore, through the coordinated operation of the corresponding components, the lead screw can be reciprocated and raised, and the screw can rotate in both directions, facilitating the reciprocating movement of the mounting plate.

[0012] Preferably, a first movable component is fixed to one side of the lower end of the mounting plate, and the lower end of the sliding frame is disposed through the first movable component.

[0013] Furthermore, this ensures the stability of the mounting plate movement.

[0014] Preferably, the reset mechanism includes a first slide rod fixed to one side of the upper clamping plate, a fixing plate slidably mounted on the first slide rod, one end of the fixing plate being fixed to one side of the mounting plate, and a first spring sleeved on the first slide rod, with the two ends of the first spring being fixed to the lower end of the fixing plate and the lower end of the first slide rod, respectively.

[0015] Furthermore, it is compatible with various specifications of intelligent monitoring components and is easy to install and remove quickly.

[0016] Preferably, the rear end of the metering cabinet assembly is provided with a base, a fixed tube is fixed on the base, an adaptation mechanism is installed on the fixed tube, a fixed seat is connected to the adaptation mechanism, and a plurality of second moving parts are installed on the adaptation mechanism. Two swing arms are rotatably connected to one side of the second moving parts, and a bushing is rotatably connected to one end of the plurality of swing arms. The bushing is rotatably sleeved on the fixed tube, and a first damper is rotatably connected to each of the plurality of swing arms located at the upper end. The first damper and the bushing are rotatably connected.

[0017] Furthermore, between the base and the metering cabinet assembly, force is transmitted through the main support chain of "fixed tube - adaptation mechanism - fixed seat", while vertical impact is absorbed through the parallel shock absorption chain of "moving component - swing arm - bushing - first damper". The bushing, as a key connection node, not only rotates by being sleeved on the fixed tube, but also, through the linkage of the swing arm with the second moving component and the first damper, converts the vertical external force into the deflection deformation of the swing arm.

[0018] Preferably, the adaptation mechanism includes a fixed plate fixed on a fixed tube, a plurality of second dampers are rotatably connected at equal intervals to the upper end of the fixed plate, and a second sliding member is rotatably connected to the piston rod end of each of the plurality of second dampers. A slide rail is slidably mounted on the second sliding member, and the slide rail is fixed on a circumferential side wall inside the fixed seat. A linkage mechanism is provided on the slide rail, and the linkage mechanism is connected to the second moving member.

[0019] Furthermore, the fixed plate serves as the mounting base for the second damper, which is fixed on the fixed tube. Multiple second dampers are distributed at equal intervals to form a ring / multi-directional damping layout. The piston rod of the second damper is connected to the second sliding member, which slides along the slide rail fixed to the inner wall of the fixed base to achieve horizontal displacement buffering. The reset mechanism is connected to the second moving member, which transmits the horizontal force to the second moving member, thus cooperating with the first damper system.

[0020] Preferably, the linkage mechanism includes a second slide rod slidably mounted on a slide rail, the second slide rod being slidably sleeved inside a second moving member, a second spring being sleeved on the second slide rod, and the two ends of the second spring being respectively fixed to one end of the second moving member and one end of the second slide rod.

[0021] Furthermore, the second slide rod slides along the slide rail and is simultaneously slidably sleeved inside the second moving part. The second spring is sleeved on the second slide rod, with its two ends anchored to the second moving part and the second slide rod, respectively. When a horizontal external force pushes the second slide rod to move along the slide rail, the reset mechanism pulls the second slide rod to compress / stretch the second spring, and the second spring deforms to absorb energy. After the external force disappears, the second spring returns to its original length, pushing the second slide rod back to its original position, thus achieving automatic reset.

[0022] Preferably, the second movable member is L-shaped, and the second slide rod passes through the lower end of the second movable member.

[0023] Furthermore, the L-shaped structure allows the second moving part to participate in the transmission of force in two directions simultaneously; one arm participates in the vertical swing arm linkage, while the lower end of the other arm is penetrated by the second slide rod, participating in the horizontal second spring reset linkage; the design of the second slide rod penetrating the lower end allows the horizontal and vertical forces to be coupled, transmitted, and buffered together through the same L-shaped moving part.

[0024] Preferably, the metering cabinet assembly and the mounting base are detachably connected.

[0025] Furthermore, detachable connections (such as bolted connections, snap-fit ​​connections, etc.) allow the metering cabinet components to be easily removed from the mounting base, facilitating the installation, maintenance, replacement, and repair of the equipment, and reducing usage and maintenance costs.

[0026] The beneficial effects of this invention are: 1. With the cooperation of heat dissipation and ventilation equipment, the gas flow inside the metering cabinet can be accelerated, and heat dissipation can be effectively achieved. At the same time, during actual production and preparation, ventilation openings are opened on the top and sides of the metering cabinet to ensure gas flow. 2. The motor assembly can drive the toothed transmission wheel and toothed transmission belt to operate, which can facilitate the sliding frame to move up and down through the sliding parts. In addition, the gear and rack can enable the lead screw to drive the lead screw nut and the mounting plate to move back and forth, which can effectively monitor multiple positions in the metering cabinet assembly, improve the efficiency and range of monitoring, and understand the status inside the metering cabinet assembly. 3. Pull the clamp at the top to easily place or remove the intelligent monitoring components. This allows for effective and quick installation and fixation, facilitating installation according to actual conditions and the specifications of the monitoring components, thus improving the practicality and applicability of the product. 4. Two-way coordinated vibration reduction, providing all-round protection for the metering cabinet components; through the coordinated operation of the main support chain of "fixed tube-adaptive mechanism-fixed seat" and the parallel damping chain of "moving component-swing rod-sleeve-first damper", precise vertical vibration reduction is achieved. When the metering cabinet components are subjected to vertical external force, the force is transmitted to the swing rod through the fixed seat. The swing rod drives the sleeve to deflect around the fixed tube, and the first damper deforms and buffers accordingly, effectively absorbing the impact energy. At the same time, multiple sets of second dampers evenly distributed on the fixed plate form a ring-shaped multi-directional vibration reduction layout, which, together with the displacement movement of the sliding component along the slide rail, achieves comprehensive horizontal buffering, providing all-round protection for the metering cabinet components.

[0027] 5. Force coupling and automatic reset, balancing efficient vibration reduction with convenient maintenance: The L-shaped moving part cleverly integrates the vertical swing arm linkage and the horizontal sliding arm linkage into one unit, enabling horizontal and vertical forces to be coupled, transmitted, and buffered collaboratively through the same component, significantly improving overall vibration reduction efficiency. The spring, as the core of the reset mechanism, automatically returns to its original length after vibration reduction, pushing the sliding part back to its position, allowing for continuous and effective operation without manual intervention. Furthermore, the metering cabinet assembly and the fixed base are detachably connected, facilitating quick disassembly and maintenance, significantly reducing equipment operation and maintenance costs.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Reference Figures 1-9 A smart grid-based box-type electricity metering box includes a metering cabinet assembly 1, which is installed in the smart grid and can fully connect users and the power grid to accurately measure and record the electricity consumed by users, serving as the direct basis for power companies to collect electricity fees from users. Its internal structure and working principle are existing technologies and do not need to be disclosed again. A heat dissipation and ventilation device 2 is installed at the top of the metering cabinet assembly 1. The heat dissipation and ventilation device 2 consists of a motor and a cooling fan, which enables the air to flow inside the metering cabinet assembly 1. At the same time, ventilation holes are opened at the top and sides of the metering cabinet assembly 1 to allow air to flow out of the metering cabinet assembly 1, effectively carrying out heat dissipation.

[0031] In this embodiment, a door panel 3 is hinged to one side of the metering cabinet assembly 1 for easy opening and closing, facilitating maintenance of the equipment inside the metering cabinet assembly 1. A circulation mechanism is installed on the door panel 3, and a sliding frame 10 is provided on the circulation mechanism. A lead screw 11 is rotatably sleeved on the sliding frame 10. The lead screw 11 and the sliding frame 10 are arranged parallel to each other. A reciprocating mechanism is installed on one side of the lead screw 11 and is connected to the door panel 3. A lead screw nut 12 is screwed onto the lead screw 11, and a mounting plate 13 is fixed to one side of the lead screw nut 12. The mounting plate 13 is slidably installed on the sliding frame 10. Clamping plates 16 are installed at both the upper and lower ends of the mounting plate 13, and the two clamping plates 16 together clamp the monitoring assembly 14. The lower clamping plate 16 is fixedly connected to the mounting plate 13, and a reset mechanism is provided on the upper clamping plate 16. The reset mechanism and the mounting plate 14 are connected together. When the mounting plate 13 is connected, the operator starts the motor assembly 8, which drives the transmission wheel 9 fixedly connected to it to rotate. The transmission wheel 9 can drive the transmission belt 7 to rotate, causing the first sliding member 6 to circulate on the transmission belt 7. The movement of the first sliding member 6 can drive the sliding frame 10 to circulate. The sliding frame 10 can drive the gear 5 to operate, so that the gear 5 and the rack 4 mesh to facilitate the rotation of the lead screw 11. When the lead screw 11 rotates, it can drive the lead screw nut 12 and the first moving member 15 to move the mounting plate 13, and can make the lead screw 11 rotate in both directions, which can facilitate the reciprocating movement and up-and-down lifting of the monitoring component 14. When installation or disassembly is required, the clamping plate 16 at the upper end can be pulled to squeeze the first spring 19, which is convenient for removing or installing the monitoring component 14.

[0032] In actual operation, the metering box can measure electricity consumption, but the monitoring component 14 can be used to monitor: Operating environment monitoring: Ensures equipment stability; monitoring environmental parameters can effectively prevent equipment failures caused by overheating, moisture, or fire. Temperature and humidity: Sensors are deployed in key areas inside the cabinet to monitor temperature and humidity, preventing equipment damage or insulation degradation due to overheating or condensation. In some designs, it can also accurately detect which specific metering instrument is overheating abnormally; Smoke and water immersion: Monitoring smoke and water immersion can provide early warnings of major risks such as fire or flooding; Monitoring the equipment and physical condition inside the cabinet is also necessary, which is key to improving operational efficiency and anti-electricity theft capabilities.

[0033] Door lock and opening status: Through technologies such as door magnetic switches and RFID / NFC tags, the cabinet door opening and closing status is monitored in real time, and the time, number of times and the identity of the operator are recorded for each opening. This is an important part of preventing electricity theft.

[0034] Status of core components: Closely monitor the operating status of core components such as current transformers (CTs), voltage transformers (PTs), electricity meters, and data acquisition terminals, including whether there are metering errors and whether communication is normal.

[0035] Physical security: Some smart metering cabinets are also equipped with vibration and displacement sensors to detect whether the cabinet has been damaged by external forces or moved illegally; The monitoring component 14 in this application can selectively install corresponding monitoring components as needed to understand the situation inside the cabinet in real time, and can upload the monitoring information for quick processing.

[0036] In this embodiment, the circulation mechanism includes a motor assembly 8 installed at the lower end of the door panel 3. A transmission wheel 9 is installed at the end of the output shaft of the motor assembly 8 and on the upper side of the door panel 3. The two transmission wheels 9 are connected by a transmission belt 7. A first sliding member 6 is rotatably connected to the transmission belt 7. A sliding frame 10 is slidably installed in the first sliding member 6 and on the door panel 3. When the operator starts the motor assembly 8, the motor assembly 8 drives the transmission wheel 9 fixedly connected to it to rotate. The transmission wheel 9 can drive the transmission belt 7 to drive the transmission wheel 9 located at the upper end to rotate, so that the first sliding member 6 circulates back and forth on the transmission belt 7. The movement of the first sliding member 6 can drive the sliding frame 10 to circulate up and down.

[0037] In this embodiment, the reciprocating mechanism includes a gear 5 fixed to one end of the lead screw 11, a rack 4 meshing on the gear 5, the rack 4 being fixed to one side of the door panel 3, the rack 4 and the lead screw 11 being arranged vertically, and as the lead screw 11 rises and falls, the gear 5 and the rack 4 can mesh in opposite directions, making it easy for the lead screw 11 to rotate in opposite directions, and enabling the monitoring component 14 to reciprocate.

[0038] In this embodiment, a first movable component 15 is fixed to one side of the lower end of the mounting plate 13, and the lower end of the sliding frame 10 is disposed inside the first movable component 15, which can ensure the stability of movement and facilitate the reciprocating movement of the monitoring component 14.

[0039] In this embodiment, the reset mechanism includes a first slide rod 18 fixed to one side of the upper clamping plate 16. A fixing plate 17 is slidably mounted on the first slide rod 18. One end of the fixing plate 17 is fixed to one side of the mounting plate 13. A first spring 19 is sleeved on the first slide rod 18. The two ends of the first spring 19 are respectively fixed to the lower end of the fixing plate 17 and the lower end of the first slide rod 18. When an external force is applied to the first spring 19, the first spring 19 can be compressed, which facilitates the adjustment of the distance between the two clamping plates 16. At the same time, when the external force is removed, the first spring 19 resets, which can drive the two clamping plates 16 to clamp the monitoring component 14. The monitoring component 14 adopts components in the prior art, which can effectively detect changes in the metering cabinet component 1, upload the detected data, and connect to corresponding equipment in the control room, such as alarm components in the control room. When a problem occurs, an alarm can be issued in time to remind the staff.

[0040] In this embodiment, a base 20 is provided at the rear end of the metering cabinet assembly 1. A fixing tube 22 is fixed on the base 20, and an adaptation mechanism is installed on the fixing tube 22. A fixing seat 21 is connected to the adaptation mechanism, and multiple second moving parts 26 are installed on the adaptation mechanism. Two swing arms 24 are rotatably connected to one side of each second moving part 26. One end of each swing arm 24 is rotatably connected to a bushing 25, which is rotatably sleeved on the fixing tube 22. A first damper 23 is rotatably connected to each of the upper swing arms 24. The base 20 is rotatably connected to the bushing 25; between the base 20 and the metering cabinet assembly 1, the force is transmitted through the main support chain of "fixed tube 22-adaptive mechanism-fixed seat 21", and at the same time, the vertical shock absorption chain of "second moving part 26-swing rod 24-shoulder sleeve 25-first damper 23" is used to absorb the vertical impact; the bushing 25, as a key connection node, is rotatably sleeved on the fixed tube 22 to achieve rotation, and is also linked with the second moving part 26 and the first damper 23 through the swing rod 24 to convert the vertical external force into the deflection deformation of the swing rod.

[0041] In this embodiment, the adaptation mechanism includes a fixed disk 31 fixed on the fixed tube 22. Multiple second dampers 30 are rotatably connected at equal intervals to the upper end of the fixed disk 31. The piston rod ends of each of the multiple second dampers 30 are rotatably connected to a second sliding member 32. A slide rail 27 is slidably mounted on the second sliding member 32. The slide rail 27 is fixed to the circumferential side wall inside the fixed base 21. A linkage mechanism is provided on the slide rail 27, which is connected to the second moving member 26. The fixed disk 31 serves as the mounting base for the second dampers 30, fixed on the fixed tube 22. The multiple second dampers 30 are evenly distributed, forming a ring / multi-directional damping layout. The piston rod of the second damper 30 is connected to the second sliding member 32, which slides along the slide rail 27 fixed to the inner wall of the fixed base 21, achieving horizontal displacement buffering. The reset mechanism is connected to the second moving member 26, transmitting horizontal force to the moving member, thus cooperating with the first damper 23 system.

[0042] In this embodiment, the linkage mechanism includes a second slide rod 28 slidably mounted on the slide rail 27. The second slide rod 28 is slidably sleeved within the second moving member 26. A second spring 29 is sleeved on the second slide rod 28, with its two ends fixed to one end of the second moving member 26 and one end of the second slide rod 28, respectively. The second slide rod 28 slides along the slide rail 27 while being slidably sleeved within the second moving member 26. The second spring 29 is sleeved on the slide rod, with its two ends anchored to the second moving member 26 and the second slide rod 28, respectively. When a horizontal external force pushes the second sliding member 32 to move along the slide rail 27, the reset mechanism pulls the second slide rod 28 to compress / stretch the second spring 29, causing the spring to deform and absorb energy. After the external force disappears, the spring returns to its original length, pushing the second sliding member 32 back to its original position, thus achieving automatic reset.

[0043] In this embodiment, the second moving member 26 is L-shaped, and the second slide rod 28 is disposed through the lower end of the second moving member 26. The L-shaped structure allows the second moving member 26 to participate in the transmission of force in two directions simultaneously. One arm participates in the vertical swing arm linkage, and the lower end of the other arm is penetrated by the second slide rod 28, participating in the horizontal spring reset linkage. The design of the second slide rod 28 penetrating the lower end allows the horizontal force and the vertical force to be coupled, transmitted, and buffered together through the same L-shaped moving member.

[0044] In this embodiment, the metering cabinet assembly 1 and the fixed base 21 are detachably connected; the detachable connection, such as bolt connection or snap connection, allows the metering cabinet assembly 1 to be easily removed from the fixed base 21, which facilitates the installation, maintenance, replacement and repair of the equipment and reduces the cost of use and maintenance.

[0045] The overall operation of this invention covers four major functional modules: power metering, circulation monitoring, heat dissipation and ventilation, and shock absorption. These modules work together to achieve comprehensive intelligent management of the metering cabinet components.

[0046] I. Electricity metering and heat dissipation / ventilation Metering cabinet component 1 is installed in the smart grid to accurately measure and record the electrical energy consumed by users, serving as the direct basis for the power company to collect electricity fees from users. A heat dissipation and ventilation device 2, consisting of a motor and a cooling fan, is installed at the top of metering cabinet component 1. During operation, the heat dissipation and ventilation device 2 drives the airflow inside the cabinet, which, together with the ventilation holes on the top and sides of metering cabinet component 1, forms air convection, effectively dissipating the heat generated by the components inside the cabinet and achieving heat dissipation.

[0047] II. Operating Principle of the Cyclic Monitoring Mechanism The door panel 3 is hinged to one side of the metering cabinet assembly 1 for easy opening and closing for maintenance. A circulation mechanism is installed on the door panel 3, the core driving component of which is the motor assembly 8 installed at the lower end of the door panel 3. After the motor assembly 8 is started, the motor assembly 8 drives the transmission wheel 9 fixedly connected to it to rotate. The transmission wheel 9 drives another transmission wheel 9 located at the upper end of the door panel 3 to rotate synchronously through the transmission belt 7, so that the first sliding member 6 on the transmission belt 7 performs cyclic reciprocating motion, thereby driving the sliding frame 10 to move up and down cyclically on the door panel 3.

[0048] A lead screw 11 is rotatably sleeved on the sliding frame 10, and a reciprocating mechanism is installed on one side of the lead screw 11. As the sliding frame 10 rises and falls, the gear 5 fixed at one end of the lead screw 11 meshes with the rack 4 fixed on one side of the door panel 3 in both directions, causing the lead screw 11 to rotate in both directions. When the lead screw 11 rotates, the lead screw nut 12 screwed onto it drives the mounting plate 13 to reciprocate along the sliding frame 10. The clamping plates 16 at the upper and lower ends of the mounting plate 13 together hold the monitoring component 14, thereby driving the monitoring component 14 to circulate and reciprocate within the metering cabinet assembly 1, achieving accurate detection of multiple locations within the metering cabinet assembly.

[0049] III. Operating Principle of the Quick-Clamping Mechanism When it is necessary to install or remove the monitoring component 14, the operator pulls the upper clamping plate 16, causing the clamping plate 16 to compress the first spring 19. The first spring 19 contracts, increasing the distance between the two clamping plates 16, making it easier to insert or remove the monitoring component 14. After being released, the first spring 19 returns to its original position, causing the clamping plate 16 to re-clamp the monitoring component 14, achieving quick installation and fixation, and adapting to monitoring components of various specifications.

[0050] IV. Operating Principle of the Shock Absorption and Buffer Mechanism The rear end of the metering cabinet assembly 1 is provided with a base 20, which is fixed to the wall. A fixing pipe 22 is fixed on the base 20, and an adaptation mechanism is installed on the fixing pipe 22. A fixing seat 21 is connected to the adaptation mechanism. The metering cabinet assembly 1 and the fixing seat 21 are detachably connected.

[0051] When the metering cabinet assembly 1 is subjected to external force or scraping, the shock absorption mechanism operates in two directions: Horizontal shock absorption: The external force is transmitted to the second damper 30 through the fixed seat 21, causing one side of the second damper 30 to be stretched and the other side to be contracted. The force is transmitted to the second slide rod 28 through the slide rail 27, causing a positional shift between the fixed seat 21 and the fixed tube 22, causing one side of the second spring 29 to be stretched and the other side to be compressed, thereby canceling out the external force. Vertical shock absorption: When the external force is applied downwards, the fixed seat 21 transmits the force to the fixed tube 22 through the second sliding member 32. The first damper 23 is compressed and deformed, and the deformation of the first damper 23 drives the swing rod 24 to deflect, converting and canceling out the external force. The L-shaped second moving member 26 integrates the vertical swing rod linkage and the horizontal slide rod linkage into one unit, enabling the horizontal and vertical forces to be coupled, transmitted, and buffered collaboratively through the same component. After shock absorption, the second spring 29 automatically returns to its original length, pushing the second sliding member 32 back to its original position, thus achieving automatic reset and continuous effective operation without manual intervention.

[0052] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
