Description

Technical Field

[0001] This utility model relates to the field of metering box technology, specifically to a metering box. Background Technology

[0002] In the public utility sectors such as electricity, water, and gas, metering boxes are specialized devices used to install metering instruments (such as electricity meters, water meters, and gas meters) and related electrical components. Their function is to accurately measure energy consumption, protect metering devices from external environmental interference and human damage, and facilitate meter reading, maintenance, and other operations.

[0003] Existing metering boxes have significant limitations in their structural connection design: traditional metering boxes mostly adopt fixed connection structures, such as welding the box body to the base and rigidly fastening each functional module with a large number of bolts. The disassembly process is cumbersome and often requires professional tools to disassemble point by point, which greatly extends the working time for maintenance or replacement. Utility Model Content

[0004] The purpose of this utility model is to provide a metering box that uses a fixing component to connect the metering box body to the support plate, thereby enabling the metering box body to be quickly disassembled and replaced.

[0005] To address the existing technical problems, this utility model provides a metering box, comprising: a metering box body; a support plate, which can be installed on a wall, wherein the metering box body is detachably disposed at the front of the support plate, a plurality of sleeves are evenly disposed on the support plate, and a positioning sleeve that can cooperate with the sleeves is disposed on the back of the metering box body, the positioning sleeve can be inserted into the sleeve, and a fixing component that can fix the metering box body to the support plate is also disposed in the positioning sleeve.

[0006] Preferably, a retaining ring is also provided inside the sleeve, and the positioning sleeve is inserted into the sleeve with its end in contact with the retaining ring.

[0007] Preferably, the positioning sleeve is further provided with a number of hinges evenly arranged inside, and the fixing component includes a number of claws that can be rotatably arranged in the positioning sleeve, and one end of the claw is provided with a fixing block, and the fixing block passes through the hole in the retaining ring and presses against the side of the retaining ring away from the positioning sleeve.

[0008] Preferably, the claw is further provided with a limiting groove, and one end of the limiting groove is far away from the center of the positioning sleeve. The hinge is also provided with a shaft that can be slidably disposed in the limiting groove.

[0009] Preferably, the fixing component further includes a movable block that can be slidably disposed in the positioning sleeve, and the movable block is movably connected to the chuck via a shaft.

[0010] Preferably, the metering box body is further provided with a screw sleeve inside, and the fixing component also includes a screw rod rotatably connected to the moving block. The screw rod is provided with an external thread on the outside, and the screw sleeve is provided with an internal thread inside. The external thread and the internal thread mesh with each other, and a rotating handle is connected to one end of the screw rod.

[0011] Preferably, the front of the metering box body is movably provided with a box door, and the side of the metering box body is also provided with heat dissipation holes.

[0012] Preferably, mounting holes are provided at the four corners of the support plate.

[0013] The advantages of this utility model compared to the prior art are:

[0014] This application achieves rapid assembly and disassembly of the metering box by optimizing the connection structure. The specific structural design is as follows: A positioning sleeve is fixedly installed on the back of the metering box body. A sleeve is correspondingly provided on the support plate that cooperates with the positioning sleeve, and a retaining ring is formed inside the sleeve. During installation, the support plate needs to be fixed to the wall surface with bolts beforehand. Then, the positioning sleeve on the back of the metering box body is aligned with the inner cavity of the sleeve and inserted axially until the end of the positioning sleeve contacts the end face of the retaining ring of the sleeve, completing the initial positioning. To achieve locking and fixing, a claw is hinged to the outer wall of the positioning sleeve. The middle of the claw has a limiting groove that matches the pin on the hinge. One end of the claw is connected to a fixed block, and the other end is movably connected to a moving block. The moving block is movably connected to a screw, and the outer end of the screw is connected to a rotating handle. When the rotating handle is rotated, the screw rotates synchronously and drives the moving block to move axially. Because the limiting groove on the claw cooperates with the shaft on the hinge, the fixed block moves towards the retaining ring and finally presses against the surface of the retaining ring, achieving a rigid connection between the metering box body and the support plate. During disassembly, simply rotating the handle in the opposite direction will reset the moving block. The chuck, engaged by the limiting groove and hinge, will disengage from the retaining ring, allowing the positioning sleeve to be directly pulled out of the sleeve, thus completing the disassembly of the metering box body. This structure effectively avoids the drawbacks of traditional metering boxes that are directly bolted to the wall. Traditional structures are prone to problems such as stripped bolt holes and deformation of the box connecting seat during repeated disassembly, leading to weakened connection strength and decreased installation stability. This application, through the insertion and engagement of the positioning sleeve and the sleeve, and the locking mechanism of the chuck, ensures structural reliability after installation, significantly simplifies assembly and disassembly operations, reduces damage to the box body and connecting components, and improves the reusability of the equipment.

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] Reference Figures 1-6As shown, this utility model provides a measuring box, including: a measuring box body 1; the measuring box body 1 serves as the core carrier for accommodating various measuring instruments and is typically made of corrosion-resistant and aging-resistant materials (such as high-strength engineering plastics or stainless steel). Its main function is to provide a relatively enclosed protective space for the internal measuring instruments, effectively blocking external factors such as dust, moisture, direct sunlight, and collisions from damaging the internal measuring instruments, ensuring that the measuring instruments are protected from environmental interference and maintaining normal measuring accuracy and working condition. A support plate 2, which can be installed on a wall, is generally made of high-strength metal materials (such as galvanized steel plates) and has good load-bearing capacity and stability. Its main function is to act as a connecting bridge between the metering box body 1 and the wall. It can be firmly installed on the wall using expansion bolts and other connectors, providing a stable support foundation for the metering box body 1, allowing the metering box to be securely installed in the designated position. The metering box body 1 is detachable and located at the front of the support plate 2. Several sleeves 21 are evenly arranged on the support plate 2, and a positioning sleeve 11 that can cooperate with the sleeves 21 is provided on the back of the metering box body 1. The positioning sleeve 11 can be inserted into the sleeve 21. The sleeve 21 is usually connected to the support plate 2 by welding or integral molding to ensure the firmness of its connection with the support plate 2. The inner diameter of the sleeve 21 matches the outer diameter of the positioning sleeve 11. It cooperates with the positioning sleeve 11 on the back of the metering box body 1 to play a positioning role when installing the metering box body 1, guiding the insertion of the positioning sleeve 11, making it convenient for installers to quickly and accurately place the metering box body 1 in the correct position, improving installation efficiency. In addition, the positioning sleeve 11 is also provided with a fixing component 12 that can fix the metering box body 1 to the support plate 2. The main function of the fixing component 12 is to firmly connect the metering box body 1 and the support plate 2 after the positioning sleeve 11 is inserted into the sleeve 21, further restricting the displacement of the metering box body 1 in the vertical and other directions, preventing the metering box body 1 from loosening or falling off due to vibration, external force collision or other reasons during use, and ensuring the overall installation stability and safety of the metering box.

[0024] First, install the support plate 2. Secure the support plate 2 to the predetermined wall position using expansion bolts or other suitable connectors. During installation, ensure the support plate 2 is horizontal and firmly connected to the wall, providing a stable foundation for the subsequent installation of the metering box body 1. Next, position and install the metering box body 1. The installer aligns the positioning sleeve 11 on the back of the metering box body 1 with the sleeve 21 on the support plate 2, then inserts the positioning sleeve 11 into the corresponding sleeve 21. Because the positioning sleeve 11 and sleeve 21 are sized to match, the metering box body 1 can be quickly positioned, ensuring it is in the correct installation position. The fit between the positioning sleeve 11 and sleeve 21 also helps prevent the metering box body 1 from shifting during installation. Finally, secure the metering box body 1 using the fixing component 12. After positioning, operate the fixing component 12 in the positioning sleeve 11 to firmly fix the metering box body 1 to the support plate 2, preventing loosening during use. Throughout the entire process, the support plate 2 continuously provides stable support for the metering box body 1, the fixing component 12 ensures a reliable connection between the metering box body 1 and the support plate 2, and the metering box body 1 provides a safe and suitable working environment for the internal measuring instruments. The three work together to ensure that the metering box can operate stably and safely, and to achieve effective protection and support for the measuring instruments.

[0025] The sleeve 21 is also provided with a retaining ring 211 inside. The positioning sleeve 11 is inserted into the sleeve 21 and the end of the positioning sleeve 11 contacts the retaining ring 211. The shape and size of the positioning sleeve 11 are adapted to the sleeve 21 and can be inserted into the sleeve 21. When it is inserted to a certain depth, the end of the positioning sleeve 11 will contact the retaining ring 211 inside the sleeve 21, at which point the insertion stops, and the initial positioning of the metering box body 1 is achieved.

[0026] The positioning sleeve 11 is further provided with a plurality of hinge members 111 evenly arranged inside. The fixing assembly 12 includes a plurality of claws 121 that are rotatably disposed in the positioning sleeve 11, and a fixing block 122 is provided at one end of each claw 121. The fixing block 122 passes through a hole in the retaining ring 211 and presses against the side of the retaining ring 211 away from the positioning sleeve 11. A limiting groove 1211 is also provided on the claw 121, and one end of the limiting groove 1211 is away from the center position of the positioning sleeve 11. The hinge member 111 is also provided with a shaft that is slidably disposed in the limiting groove 1211. The fixing assembly 12 also includes a moving block 123 that is slidably disposed in the positioning sleeve 11, and the moving block 123 is movably connected to the claw 121 via a shaft. The metering box body 1 is also provided with a screw sleeve 13 inside. The fixing component 12 also includes a screw 124 that is rotatably connected to the moving block 123. The screw 124 is provided with an external thread on the outside and an internal thread on the inside of the screw sleeve 13. The external thread and the internal thread mesh. One end of the screw 124 is connected to a rotating handle 1241.

[0027] Insert the positioning sleeve 11 into the corresponding sleeve 21. During the insertion process, as the positioning sleeve 11 goes deeper, its end will gradually approach the retaining ring 211 inside the sleeve 21. When the end of the positioning sleeve 11 contacts the retaining ring 211, it indicates that the positioning sleeve 11 has been inserted to the preset depth, and the insertion operation is stopped at this time. The operator rotates the rotating handle 1241 inside the metering box body 1, causing the screw 124 to rotate synchronously. The screw 124 engages with the screw sleeve 13 and is pushed axially toward the positioning sleeve 11, pushing the moving block 123 to slide inside the positioning sleeve 11. When the moving block 123 slides, it can push the pawl 121 to move. Due to the action of the limiting groove 1211, the shaft on the hinge 111 slides along the limiting groove 1211 of the pawl 121, restricting the pawl 121 to rotate along the preset trajectory. During the rotation of the pawl 121, the fixing block 122 at its end presses against the side of the retaining ring 211 away from the positioning sleeve 11. Through the synchronous pressing action of multiple pawls 121, the positioning sleeve 11 and the sleeve 21 are firmly locked, completing the fixation of the metering box body 1.

[0028] The front of the measuring chamber body 1 is equipped with a movable door 14, and the side of the measuring chamber body 1 is also provided with heat dissipation holes 15. The function of the heat dissipation holes 15 is to promote air circulation between the inside of the measuring chamber body 1 and the outside, so as to dissipate the heat generated by the internal measuring instruments in a timely manner, and avoid affecting the normal working accuracy and service life of the measuring instruments due to excessive internal temperature.

[0029] Mounting holes 22 are provided at the four corners of the support plate 2. The size of the mounting holes 22 is adapted to the connecting parts such as expansion bolts. Its main function is to act as a connecting bridge between the metering box body 1 and the wall, and it can be firmly installed on the wall by connecting parts such as expansion bolts passing through the mounting holes 22.

[0030] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
