Description

Technical Field

[0001] This utility model relates to the field of electricity meter technology, specifically to a track-mounted electricity meter. Background Technology

[0002] In the field of modern electricity metering, track-mounted energy meters are widely used in various electricity metering scenarios due to their convenient installation method. The track groove on the bottom wall of the energy meter casing is compatible with the matching track, enabling the energy meter to be quickly installed and fixed.

[0003] However, a significant drawback of current track-mounted energy meters is that the width of the track groove is fixed. Tracks from different manufacturers, or those required for different applications, often have varying widths. When an existing track-mounted energy meter cannot be properly installed on a track with a mismatched width, or even if it is installed with difficulty, its stability and secureness cannot be guaranteed. Over long-term use, this can lead to metering errors due to poor contact, and may even pose safety hazards.

[0004] To address this issue, some technicians have attempted to develop adjustable track connection structures, but most of these solutions are too complex, which not only increases the production cost of electricity meters but may also reduce the reliability and stability of the products, leading to increased maintenance costs.

[0005] Therefore, how to develop a track-mounted energy meter that is simple in structure, cost-controllable, and can effectively adjust the width of the track groove to adapt to tracks of different widths has become an important problem that urgently needs to be solved in this field. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a track-mounted energy meter.

[0007] The technical solution adopted by this utility model is: a track-mounted energy meter, including an energy meter housing, a track groove for fitting and installing with a track on the bottom wall of the energy meter housing, a movable groove on one side of the energy meter housing, a track insert plate movably connected in the movable groove, and an adjustment mechanism for driving the track insert plate to move up and down on the bottom wall of the energy meter housing.

[0008] Furthermore, the adjustment mechanism includes a rotating shaft rotatably connected to the outer casing of the electricity meter, a drive gear on one end of the rotating shaft, and a knob on the other end of the rotating shaft. The track plate is provided with a drive rack that drives and cooperates with the aforementioned drive gear.

[0009] Furthermore, the track insert includes a pressure plate and a hanging plate connected to the pressure plate. The hanging plate is provided with a toothed groove, and the aforementioned drive rack is provided on one side of the toothed groove. The drive gear is located in the toothed groove and drives and engages with the drive rack.

[0010] Furthermore, a handle is formed by protrusions on the end face of the knob.

[0011] Furthermore, the mounting plate is provided with hanging holes.

[0012] The beneficial effects of this utility model are:

[0013] 1. Improved adaptability: The width of the track groove can be flexibly adjusted via an adjustment mechanism, accommodating tracks of different widths. This greatly enhances the compatibility of this track-mounted energy meter with various tracks. Whether it's a track from a different manufacturer or a track with a special width required for specific scenarios, stable installation can be achieved. This effectively solves the problem of fixed track groove width in existing products and significantly improves the product's versatility.

[0014] 2. Enhanced Installation Stability: While adapting to different tracks, the track groove width can be precisely adjusted according to the actual track width, resulting in a tighter and more stable fit between the electricity meter and the track. Compared to the potential loosening that may occur when installing a traditional fixed-width track groove on an incompatible track, this design effectively reduces the risk of the electricity meter becoming loose on the track due to vibration, external forces, and other factors, ensuring long-term stable operation of the electricity meter and guaranteeing the accuracy of metering.

[0015] 3. Improved Installation Ease: The adjustable mechanism simplifies track groove width adjustment. During on-site installation, installers can quickly adjust the track groove width to fit the track without additional complex tools or cumbersome procedures, simply by operating the adjustment mechanism. This significantly saves installation time, improves efficiency, and reduces labor costs.

[0016] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

If the specific posture changes, the directional indicators will also change accordingly.

[0022] This utility model provides a track-mounted energy meter.

[0023] In this embodiment, refer to Figure 1-2 The track-mounted energy meter includes an energy meter housing 1. The bottom wall of the energy meter housing 1 is provided with a track groove 2 for installation in conjunction with a track. The energy meter housing on one side of the track groove 2 is provided with a movable groove 3. A track insert plate 4 is movably connected in the movable groove 3. The bottom wall of the energy meter housing is provided with an adjustment mechanism 5 for driving the track insert plate to move up and down.

[0024] In the above technical solution, a movable slot and a track plate are provided on the outer casing of the electricity meter. The track plate is movably positioned within the movable slot, and an adjustment mechanism is provided. The track plate can be adjusted up and down via this mechanism, indirectly adjusting the width of the track slot to accommodate tracks of different widths. This frees the electricity meter from the limitation of a fixed-width track slot. The adjustment mechanism drives the track plate to flexibly change the track slot width, greatly improving the meter's adaptability to tracks of different widths. This solves the problem of fixed-width, non-adjustable track slots in traditional track-mounted electricity meters, significantly enhancing the product's versatility and practicality.

[0025] Specifically, the adjustment mechanism 5 includes a rotating shaft 6 rotatably connected to the outer casing of the electricity meter, a drive gear 7 on one end of the rotating shaft 6, and a knob 8 on the other end of the rotating shaft.

This mechanical transmission method is intuitive and convenient to operate; installers only need to turn the knob to complete the adjustment, improving the ease and controllability of adjustment while reducing the manufacturing cost and maintenance difficulty of the adjustment mechanism.

[0027] Specifically, the track insert 4 includes a pressure plate 10 and a hanging plate 11 connected to the pressure plate 10. The hanging plate 11 is provided with a toothed groove 12, and the aforementioned drive rack is provided on one side of the toothed groove 12. The drive gear is located in the toothed groove and drives and cooperates with the drive rack.

[0028] In this embodiment, as Figure 2 As shown, the track insert is designed as a "T"-shaped structure connected by a pressure plate and a hanging plate. A toothed groove is provided on the hanging plate, and the drive rack is positioned on one side of the groove, allowing the drive gear to mesh with the rack within the groove. This design not only optimizes the track insert's structure, enhances its overall integrity, reduces its overall volume, and ensures transmission stability, but also provides excellent guidance and protection for the meshing of the drive gear and rack, reducing wobbling and misalignment during transmission. This further improves the accuracy and reliability of adjustment, ensuring the track insert moves smoothly and steadily during adjustment and guaranteeing the precision of the track groove width adjustment.

[0029] Specifically, a handle 13 is formed by a protrusion on the end face of the knob.

[0030] In this embodiment, a handle 13 is formed by protrusion on the end face of the knob, which further improves the convenience of knob operation.

[0031] Specifically, the mounting plate is provided with hanging holes 14.

[0032] In this embodiment, mounting holes are provided on the mounting plate, offering more fixing methods and options for the installation of the electricity meter.
