Description

Technical Field

[0001] This utility model relates to the field of power equipment technology, specifically to a rail-mounted power metering device. Background Technology

[0002] In the field of power equipment, rail-mounted three-phase meters are widely used in meter boxes, distribution cabinets, and other similar applications. In existing technologies, three-phase meters are typically fixed directly to the rail with bolts. Installation and disassembly require repeated tightening of screws using tools, making the process cumbersome and inefficient. While some three-phase meters employ a snap-fit ​​structure, which simplifies installation, they still suffer from unstable fastening and are prone to loosening and detachment. Furthermore, they are difficult to adapt to standard rails of varying thicknesses. Therefore, we propose a rail-mounted energy metering device. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a rail-mounted power metering device to solve the problems existing in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A rail-mounted energy metering device, including a three-phase meter, is characterized by comprising:

[0006] Mounting bracket, fixed to the back of the three-phase meter;

[0007] Support plates are located on both sides of the mounting base and are equipped with lower clips;

[0008] A sliding seat is slidably disposed on the mounting base;

[0009] A sliding plate is provided on both sides of the sliding seat and is equipped with an upper buckle;

[0010] A tension spring connects the upper and lower buckles;

[0011] Pressing the sliding seat causes the upper and lower buckles to move away from each other to release the guide rail. After releasing, the tension spring drives the upper and lower buckles to engage the guide rail.

[0012] Preferably, the abutment plate extends in the direction of the guide rail and is arranged parallel to the guide rail body.

[0013] Preferably, the sliding plate and the supporting plate are on the same plane.

[0014] Preferably, the lower buckle is located on the support plate near the end of the three-phase meter, and the upper buckle is located on the sliding plate near the head end of the three-phase meter.

[0015] Preferably, the mounting base is provided with an upper baffle, the sliding base is provided with a lower baffle, and the two ends of the tension spring are fixed to the upper baffle and the lower baffle.

[0016] Preferably, the sliding seat has an oblong hole, and the mounting seat has a protruding hole. The protrusion of the protruding hole abuts against the end face of the oblong hole, limiting the maximum sliding stroke of the sliding seat.

[0017] Preferably, the protruding hole also serves as a bolt connection hole for fixing the mounting base to the three-phase meter.

[0018] Preferably, the mounting base has bends at both ends, which form guide channels for the sliding base to slide.

[0019] This utility model provides a rail-mounted power metering device. It has the following advantages:

[0020] 1. Through the linkage design of the sliding seat, tension spring and mounting base, pressing the sliding seat will stretch the tension spring to release the installation space, and after releasing, it will automatically reset and snap into the guide rail. No tools are required throughout the process, which greatly improves the operating efficiency.

[0021] 2. Secure and prevents loosening: The tension spring provides continuous clamping force, ensuring that the upper and lower clips are tightly engaged in the grooves along the upper and lower edges of the guide rail, effectively preventing displacement or detachment caused by vibration during equipment operation.

[0022] 3. Wide compatibility with guide rails: The sliding seat's waist-shaped hole and the mounting seat's convex hole allow for flexible adjustment of the engagement distance, making it compatible with standard guide rails of different thicknesses. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, what is described is only a part of this utility model, not all of it. Based on this utility model, all other inventions obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] See attached document Figure 1-5 The rail-mounted electricity metering device includes a three-phase meter 1 and a mounting base 3 that is bolted to the back of the three-phase meter 1. The mounting base 3 is fastened to the rail on the meter box.

[0031] On both sides of the mounting base 3, there is a pair of parallel support plates 31 extending in the direction of the guide rail. The support plates 31 are parallel to the main body of the guide rail. Near the tail end of the three-phase meter 1, the support plates 31 are connected to a buckle 32 corresponding to the groove on the lower edge of the guide rail.

[0032] A sliding seat 4 is slidably disposed on the mounting base 3 along the head and tail direction of the three-phase meter 1. A pair of sliding plates 41 corresponding to the supporting plate 31 are extended on both sides of the sliding seat 4 in the direction of the guide rail. The supporting plate 31 and the sliding plate 41 are on the same plane. An upper buckle 42 corresponding to the upper edge groove of the guide rail is connected to the sliding plate 41 near the head end of the three-phase meter 1. A tension spring 5 is also connected between the upper buckle 42 and the lower buckle 32 so that the upper buckle 42 and the lower buckle 32 move closer to each other to complete the fastening with the upper and lower edge grooves of the guide rail.

[0033] During installation, manually press the sliding seat 4 to make it slide towards the head end of the three-phase meter 1 against the tension of the tension spring 5. Stretch the tension spring 5 to store force, pressing the support plate 31 of the mounting base 3 against the guide rail body. Align the lower buckle 32 with the lower edge slot of the guide rail and insert it into the lower edge slot. Release the pressed sliding seat 4. Under the force of the tension spring 5, the sliding seat 4 automatically returns to its original position and slides towards the tail end of the three-phase meter 1, causing its upper buckle 42 to engage with the upper edge slot of the guide rail, thus completing the fixation of the three-phase meter 1. The sliding stroke of the sliding seat 4 and the length design of the oblong hole 44 allow this mounting component to adapt to different thicknesses of standard guide rails, making installation and retraction extremely convenient.

[0034] The mounting base 3 is also provided with a bend 35 at the head and tail sections, and a channel is formed between the bends 35 for the sliding base 4 to slide up and down, so as to provide guidance for the sliding base 4 to slide on the mounting base 3.

[0035] A protruding hole 34 extending from the guide rail is provided at the channel of the mounting base 3, which facilitates the connection and fixation of the mounting base 3 and the three-phase meter 1 by bolts. The first function of the protruding hole 34 is as a bolt connection hole, and the protruding hole 34 is located at the channel of the mounting base 3. The protruding hole 34 and the waist-shaped hole 44 opened on the sliding seat 4 are in the same direction. When the sliding seat 4 slides to the limit position, the boss structure of the protruding hole 34 will abut against the inner wall of the end face of the waist-shaped hole 44, thereby limiting the maximum sliding stroke of the sliding seat 4, that is, preventing the tension spring from being overstretched, and playing a role in limiting the sliding distance of the sliding seat 4.

[0036] An upper baffle 33 is provided at the channel on the mounting base 3, and a lower baffle 43 is provided on the sliding base 4. The lower baffle 43 and the upper baffle 33 are parallel and on the same straight line. The two ends of the tension spring 5 are connected to the lower baffle 43 and the upper baffle 33 to reset the sliding base 4.

[0037] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0038] The above description is only used to illustrate the technical solutions of this utility model, and is not intended to limit it. Although the utility model has been described in detail with reference to the foregoing, those skilled in the art should understand that modifications can still be made to the foregoing technical solutions, or equivalent substitutions can be made to some of the technical features.
