Abstract
Description
Technical Field
[0001] This utility model relates to the field of electricity meter testing technology, specifically a multi-station electricity meter testing fixture. Background Technology
[0002] Existing electricity meter testing fixtures typically employ multiple independent workstations, but their core drawback lies in their reliance on manual operation for connecting and disconnecting electricity meters. This traditional approach presents a series of problems that urgently need to be addressed, making it difficult to meet the demands of modern industry for high efficiency, high precision, and high safety.
[0003] First and foremost, inefficiency is its most prominent drawback. In large-scale production, operators must place each electricity meter individually at its designated station and manually plug and unplug test leads. This repetitive and tedious process consumes a significant amount of time and manpower. The independent operation of each station serializes the entire testing process, thus slowing down the overall testing progress. This efficiency bottleneck is particularly pronounced when the number of electricity meters is large, directly impacting the production line's throughput.
[0004] Secondly, the inconsistency and high labor intensity of manual operations are also significant issues. Because it relies entirely on manual labor, the different operating habits, skill levels, and fatigue levels of different operators all affect the consistency of the operation. For example, when manually plugging and unplugging test leads, problems such as loose connections, poor contact, or misaligned plugs may occur. These uncertainties directly affect the accuracy and stability of the test results and may even lead to misjudgments. At the same time, frequent bending and plugging / unplugging actions are repetitive physical labor for operators, and prolonged work can easily lead to fatigue, reducing work efficiency and increasing the risk of human error.
[0005] Finally, the traditional method presents potential safety hazards. In a live-line testing environment, manually plugging and unplugging test leads undoubtedly increases the risk of electric shock for operators. Any improper action or accident could lead to serious consequences. To ensure personnel safety, additional protective measures and strict operating procedures are required, which further increases the complexity and cost of the operation. Utility Model Content
[0006] The main purpose of this utility model is to overcome the shortcomings of the prior art and provide a multi-station energy meter testing fixture, which aims to solve the problems of low testing efficiency, poor consistency, high labor intensity and safety hazards caused by reliance on manual operation in the prior art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] A multi-station energy meter testing fixture includes a chassis; the chassis is provided with a support plate that can slide in a vertical direction, and the support plate has multiple slots for inserting energy meters.
[0009] The chassis contains a wiring block corresponding to the card slot position, and a constant current power supply is provided inside the chassis, which is electrically connected to the wiring block.
[0010] The chassis also houses a drive assembly for driving the support plate to slide vertically, thereby synchronously connecting or disconnecting all energy meters on the support plate from their corresponding terminals. The drive assembly includes a drive rod rotatably mounted to the chassis, a driven rod fixed to the support plate, and a threaded connection between the driven rod and the drive rod. A first helical gear is fitted onto the outer wall of the drive rod, and a second helical gear is rotatably mounted on the chassis, meshing with the first helical gear. This mechanical structure smoothly converts rotational motion into linear vertical motion of the support plate.
[0011] The support plate is also equipped with a fixing component to stably fix the electricity meter in the slot.
[0012] Furthermore, the fixing component includes:
[0013] Base connection part: used for connection with the support plate;
[0014] Drive component: mounted on the base connection portion, used to provide power for the clamping action;
[0015] Transmission gear: connected to the output shaft of the drive component;
[0016] Clamping arms: Includes two symmetrically arranged clamping arms. One end of each clamping arm is hinged to the base connection via a pivot, and the other end is a clamping claw for clamping the energy meter. A sector gear is fixed near the transmission gear on each clamping arm. The sector gear meshes with the transmission gear, allowing the power of the drive component to be synchronously transmitted to the two clamping arms, achieving symmetrical clamping or releasing actions.
[0017] Linkage: Each of the clamping arms is also connected to at least one linkage, the other end of which is hinged to the base connection to enhance the stability of the clamping structure.
[0018] Furthermore, for ease of operation, a handle is rotatably provided on the chassis, and the handle is fixedly connected to the second helical gear. The operator can drive the entire drive assembly by turning the handle, thereby raising and lowering the support plate.
[0019] Furthermore, in order to improve the reliability of clamping and protect the housing of the electricity meter, the surface of the clamping claw is provided with a friction layer or a soft layer.
[0020] Furthermore, in order to facilitate the storage of tools or related documents, the chassis is provided with storage slots.
[0021] Furthermore, to ensure stable operation of the equipment over a long period, a cooling fan is installed on the chassis to dissipate heat from the constant current power supply. Compared with existing technologies,
[0022] This utility model has the following significant beneficial effects:
[0023] 1. Significantly improves detection efficiency: By controlling the overall lifting and lowering of the carrier plate through the drive component, multiple energy meters and wiring blocks can be connected and disconnected synchronously and quickly, changing the traditional serial operation to parallel operation, which greatly shortens the auxiliary time of a single detection and improves the overall detection efficiency.
[0024] 2. Ensure connection consistency and reliability: The mechanized connection method ensures that the connection force and position height of each electricity meter are consistent, avoiding poor contact caused by uneven force and position deviation during manual operation, thereby improving the accuracy and stability of the test results.
[0025] 3. Reduce labor intensity: Operators only need to rotate the handle or start the drive to complete the clamping and electrical connection of all energy meters, freeing operators from heavy and repetitive physical labor, reducing labor intensity and reducing human error caused by fatigue.
[0026] 4. Improved operational safety: The entire electrical connection process is completed inside the mechanical structure, eliminating the need for operators to manually touch live terminals, effectively isolating the risk of electric shock and significantly improving operational safety.

[0036] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.
[0037] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0038] Example 1
[0039] Please see Figures 1 to 3 This utility model provides a multi-station energy meter testing fixture. The fixture includes a housing 1, on which a support plate 2 that can slide vertically is provided. Multiple slots 21 are evenly provided on the support plate 2 for placing the energy meter to be tested.
[0040] Inside the chassis 1, a wiring block 3 is provided at the position corresponding to each card slot 21. All wiring blocks 3 are electrically connected to a constant current power supply 4 via wires, which provides a stable current for the energy meter detection. To ensure the stability of the constant current power supply 4 under long-term operation, a cooling fan 8 is also installed on the chassis 1 to provide forced air cooling for the constant current power supply 4.
[0041] One of the core features of this invention lies in its drive component 5, which is used to drive the vertical lifting and lowering of the support plate 2. For example... Figure 2As shown, the drive assembly 5 includes one or more vertically arranged drive rods 51, which are rotatably connected to the housing 1 via bearings. A driven rod 52 corresponding to the drive rod 51 is fixed on the support plate 2. The driven rod 52 has an internal thread that engages with the thread of the drive rod 51. A first helical gear 53 is fixedly fitted onto the outer wall of the drive rod 51. Simultaneously, a second helical gear 54 is mounted on the housing 1 via a rotating shaft, and this gear meshes with the first helical gear 53. A handle 6 is connected to the outside of the housing 1, and the handle 6 is coaxially and fixedly connected to the second helical gear 54.
[0042] When testing is required, the operator first places multiple energy meters into the slots 21 of the support plate 2. Then, the handle 6 is turned clockwise (or counterclockwise), causing the second helical gear 54 to rotate, which in turn drives the first helical gear 53 to rotate, thereby rotating the drive rod 51. Due to the threaded connection between the driven rod 52 and the drive rod 51, the rotation of the drive rod 51 is converted into a linear vertical movement (e.g., upward movement) of the support plate 2. When the support plate 2 rises to the predetermined position, the terminals of all the energy meters on it are simultaneously and accurately connected to the wiring block 3 inside the chassis 1, completing the construction of the electrical path. After the test is completed, the handle 6 is turned in the opposite direction, and the support plate 2 will descend smoothly, causing all the energy meters to disconnect from the wiring block synchronously.
[0043] To securely hold the energy meter during lifting and testing, a fixing component 7 is provided next to each slot 21 of the support plate 2. For example... Figure 3 As shown, the fixing assembly 7 includes a base connection 71 on which a drive element 72 (e.g., a micro motor or solenoid valve) is mounted. The output shaft of the drive element 72 is connected to a transmission gear 73. Two symmetrical clamping arms 74 are also hinged to the base connection 71. The ends of the clamping arms 74 are clamping claws 741 with a friction layer or soft layer to increase friction and prevent scratching the electricity meter casing. Each clamping arm 74 is fixed with a sector gear 742, and both sector gears 742 mesh with the transmission gear 73 simultaneously. After the drive element 72 is activated, the transmission gear 73 rotates, simultaneously driving the two sector gears 742, causing the two clamping arms 74 to move synchronously towards or away from each other, thereby achieving automatic clamping or releasing of the electricity meter. To increase the stability of the structure, the clamping arms 74 are also hinged to the base connection 71 via a connecting rod 75.
[0044] In addition, for convenient daily use, a storage slot 9 is provided on the side of the chassis 1, which can be used to place operation manuals, record sheets or small tools.
[0045] In summary, this utility model, through ingenious mechanical linkage design, achieves efficient, synchronous, safe and reliable automated detection connection of multi-station energy meters, effectively solving many pain points in the existing technology.
[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
