[0001] The present application relates to the field of a guide rail type electric energy meter, and in particular to an installation structure of a guide rail type electric energy meter. Background Art

[0002] The rail-mounted watt-hour meter, also known as the rail-mounted watt-hour meter or the analog watt-hour meter, is a type of power metering equipment designed for easy installation and flexible configuration. The rail-mounted watt-hour meter is installed on the rail, which is convenient for quick installation and replacement without the need for a complex fixed structure.

[0003] Generally speaking, the outer side of the bottom shell of the guide rail type electric energy meter is provided with a guide rail installation groove, through which the guide rail type electric energy meter can be clamped on the guide rail. The bottom shell is also provided with a buckle for clamping the guide rail type electric energy meter to the guide rail.

[0004] During the installation of rail-type watt-hour meters, the clearance between the rail-type watt-hour meter and the rail is often too small or too large. Utility Model Content

[0005] The present application provides a guide rail type electric energy meter installation structure, the buckle used in the guide rail type electric energy meter installation structure can be in contact with the guide rail under the action of elasticity, has a good tolerance for the dimensional deviation of the guide rail, can improve the matching degree between the guide rail type electric energy meter and the guide rail, so that the guide rail type electric energy meter can be stably installed on the guide rail. The buckle is simple in composition and easy to install.

[0006] The technical solutions of the utility model are as follows:

[0007] The present application provides a guide rail type electric energy meter installation structure, including a bottom shell and a buckle, wherein the outer side of the bottom shell is provided with a guide rail installation groove and a buckle installation groove which are interconnected, and the guide rail installation groove is used to be engaged with the guide rail so as to clamp the electric energy meter on the guide rail. The buckle is provided on one side of the guide rail installation groove in the width direction. The buckle is installed through the buckle installation groove. The buckle includes an integrally formed head and an elastic telescopic portion, wherein the head is closer to the guide rail installation groove than the elastic telescopic portion, the head is used to abut the guide rail, and the elastic telescopic portion is used to provide an elastic extrusion force toward the guide rail for the head, and enables the head to move away from or toward the guide rail installation groove.

[0008] Through the guide rail type electric energy meter installation structure provided by the present application, during the installation process of the guide rail type electric energy meter, the opening width of the guide rail installation slot gradually widens by squeezing the elastic expansion part of the buckle by external force, and finally the guide rail can enter the guide rail installation slot, and the head of the buckle abuts against the guide rail under the action of the elastic force of the elastic expansion part. Since the opening width of the guide rail installation slot gradually widens during the installation of the electric energy meter, and after the installation, the head of the buckle abuts against the guide rail under the action of the elastic force of the elastic expansion part, therefore, the guide rail type electric energy meter installation structure of the present application can be installed with a guide rail with a larger size or a guide rail with a smaller size, and has a good tolerance for the size deviation of the guide rail, which can improve the matching degree between the guide rail type electric energy meter and the guide rail, so that the guide rail type electric energy meter can be stably installed on the guide rail.

[0009] In a possible design, the head includes an abutment surface. Along the depth direction of the guide rail installation groove, the abutment surface is located on one side of the head close to the bottom surface of the guide rail installation groove, and there is a distance between the abutment surface and the bottom surface of the guide rail installation groove to form a clamping groove of the guide rail.

[0010] The guide rail type electric energy meter installation structure provided by this embodiment has a head including an abutment surface, and the abutment surface and the bottom surface of the guide rail installation groove form a guide rail clamping groove. During the clamping process of the guide rail type electric energy meter and the guide rail, one end of the guide rail can be inserted into the clamping groove. The clamping groove has a certain limiting effect on the guide rail, which can prevent the guide rail from escaping from the depth direction of the guide rail installation groove, thereby improving the stability of the guide rail type electric energy meter and the guide rail installation.

[0011] In a possible design, the abutting surface is a plane parallel to the bottom surface of the guide rail installation groove.

[0012] The guide rail type electric energy meter installation structure provided by this embodiment helps the buckle to apply a squeezing force to the guide rail in the width direction of the guide rail, so that the guide rail type electric energy meter can be stably connected to the guide rail.

[0013] In a possible design, the head also includes a sliding surface, which is located on the side of the head away from the bottom surface of the guide rail mounting groove along the depth direction of the guide rail mounting groove, and the sliding surface is an inclined surface inclined relative to the bottom surface of the guide rail mounting groove.

[0014] With the guide rail type electric energy meter installation structure provided in this embodiment, when the guide rail type electric energy meter is clamped with the guide rail, due to the setting of the sliding surface of the buckle head, the lower end of the guide rail will slide into the slot along the sliding surface under the pressure. The setting of the sliding surface makes the installation of the guide rail type electric energy meter easier and more labor-saving.

[0015] In a possible design, the head also includes a positioning surface. Along the width direction of the guide rail mounting groove, the positioning surface is the bottom surface of the card slot. The buckle mounting groove has a positioning wall. The positioning wall can abut against the positioning surface to prevent the buckle from falling out of the buckle mounting groove.

[0016] Through the guide rail type electric energy meter installation structure provided by this embodiment, before the guide rail type electric energy meter is installed on the guide rail, the clip is installed in the clip installation groove, and the positioning surface of the clip head abuts against the positioning wall of the clip installation groove. In this way, the clip can be prevented from escaping from the installation groove and causing the clip to fall off.

[0017] In a possible design, the elastic telescopic part is wavy, one end of the elastic telescopic part is fixedly connected to the head, and the other end of the elastic telescopic part is a free end. A boss abutting against the free end is provided in the buckle installation groove.

[0018] With the guide rail type electric energy meter installation structure provided by this embodiment, the elastic expansion part is wavy, and the wavy elastic expansion part can meet the requirements of the buckle for expansion amount and elastic force. The wavy elastic expansion part can be integrally injection molded with the head, which is convenient for processing. In addition, a boss abutting the free end is provided in the buckle installation groove, and the free end of the elastic expansion part abuts the boss to continuously ensure that the guide rail type electric energy meter is firmly connected to the guide rail.

[0019] In a possible design, the buckle also includes a positioning portion, and the positioning portion includes a first positioning portion and a second positioning portion that are connected to each other, the first positioning portion is fixedly connected to the head, and the second positioning portion is located at an end of the first positioning portion away from the head. Along the depth direction of the guide rail mounting groove, the first positioning portion includes a first surface and a second surface that are relatively arranged, and the second positioning portion includes a third surface and a fourth surface that are relatively arranged, the first surface and the third surface are located on the same side of the positioning portion, and the second surface and the fourth surface are located on the same side of the positioning portion. There is a height difference between the first surface and the third surface. The second surface is provided with an avoidance notch relative to the fourth surface, so as to facilitate the buckle to be installed in the buckle mounting groove. Along the depth direction of the guide rail mounting groove, the buckle mounting groove includes a first groove wall and a second groove wall that are relatively arranged, the first surface abuts against the first groove wall, and the fourth surface abuts against the second groove wall.

[0020] With the guide rail type electric energy meter installation structure provided by this embodiment, when the buckle is installed, the second positioning portion of the buckle first enters the buckle installation groove, and the fourth surface of the second positioning portion abuts against the second groove wall, and then the first positioning portion enters the buckle installation groove, and the first surface of the first positioning portion abuts against the first groove wall. In this way, the position of the buckle in the buckle installation groove is determined along the depth direction of the guide rail installation groove. The determination of the position of the buckle in the buckle installation groove along the depth direction of the guide rail installation groove helps the buckle to be connected with the guide rail, reducing the phenomenon of biased or unstable clamping.

[0021] In a possible design, the positioning portion further includes a guide surface, which is connected between the first surface and the third surface, so that the third surface smoothly transitions to the first surface.

[0022] With the guide rail type electric energy meter installation structure provided by this embodiment, there is a height difference between the first surface of the first positioning part and the third positioning surface of the second positioning part, and a guide surface is provided between the first surface and the third surface. In this way, when the buckle is installed, the second positioning part of the buckle first enters the buckle installation groove, and the first positioning part of the buckle can slide smoothly into the buckle installation groove along the guide surface under the guidance of the guide surface. The provision of the guide surface makes the installation of the buckle easier.

[0023] In a possible design, there are two positioning portions, and the two positioning portions are located on both sides of the elastic telescopic portion in the width direction.

[0024] The guide rail type electric energy meter installation structure provided by this embodiment has two positioning parts arranged on both sides of the width direction of the elastic telescopic part, which helps the elastic force of the elastic telescopic part to act on the middle position in the width direction of the head, thereby helping to ensure stable contact between the buckle head and the guide rail, thereby improving the clamping stability.

[0025] In a possible design, the buckle also includes a tail portion, which is connected to an end of the positioning portion away from the head portion, and the tail portion is provided with a tool hole, which is exposed on the outside of the bottom shell.

[0026] With the guide rail type electric energy meter installation structure provided by this embodiment, when disassembling, a screwdriver can be inserted into the tool hole to squeeze the buckle downward to separate the buckle from the guide rail, thereby disassembling the guide rail type electric energy meter.

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims and the accompanying drawings of this application are intended to cover non-exclusive inclusions.

[0040] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase "embodiments" in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0041] In addition, the terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects rather than to describe a specific order, and may explicitly or implicitly include one or more of the features.

[0042] In the description of the present application, unless otherwise specified, "plurality" means more than two (including two), and similarly, "multiple groups" means more than two groups (including two).

[0043] In the description of the present application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, the "connection" or "connection" of a mechanical structure may refer to a physical connection. For example, the physical connection may be a fixed connection, such as a fixed connection through a barrier member, such as a fixed connection through screws, bolts or other barrier members. The physical connection may also be a detachable connection, such as a mutual snap-on or snap-fit ​​connection. The physical connection may also be an integral connection, such as a connection formed by welding, bonding or integral molding. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0044] The rail-type electric energy meter adopts the rail installation method, which is convenient for quick installation and replacement. The rail-type electric energy meter generally includes a cover and a bottom shell that fit together. The space between the cover and the bottom shell is used to install electronic components. The cover is usually provided with some logos and display screens. The side of the bottom shell away from the cover will form a connected rail installation groove and a buckle installation groove. The rail installation groove is used to snap with the rail. The buckle installation groove is located on one side of the width direction of the rail installation groove, and a buckle is provided at the buckle installation groove.

[0045] In a related technology, the buckle has a fixed moving distance relative to the guide rail mounting groove. When the electric energy meter is installed on the guide rail, the buckle can only move a fixed distance in the direction away from the guide rail mounting groove so that the electric energy meter can be smoothly hung on the guide rail. Afterwards, the buckle is moved a fixed distance in the direction close to the guide rail mounting groove so that the buckle can abut the guide rail, thereby allowing the electric energy meter to be stably mounted on the guide rail.

[0046] In actual applications, the width of different rails will vary. Some rails are slightly wider than the standard size, while others are slightly narrower than the standard size. Since the buckle can only move a fixed distance toward or away from the rail mounting slot, the rail-type energy meter can be well mounted on the rail for some rails with appropriate widths. However, for some rails with smaller widths, the rail-type energy meter will not be tightly mounted on the rail and will be loose. For some rails with larger widths, the rail-type energy meter will not be able to be mounted on the rail and will not fit in.

[0047] In another related technology, the buckle is composed of at least two independent parts, which is inconvenient to assemble.

[0048] The present application provides a guide rail type electric energy meter installation structure which can overcome the defects in the above related technologies. Figure 1 Shown is a schematic diagram of the guide rail type electric energy meter installation structure and guide rail clamping structure provided in an embodiment of the present application. Figure 2 for Figure 1 Side view of. Figure 3 for Figure 2 A partial enlarged view of point B in the middle. Figure 4 A schematic diagram of the installation structure of a guide rail type electric energy meter provided in an embodiment of the present application. Figure 5 for Figure 4 AA cross-section diagram.

[0049] Please refer to Figure 1 , Figure 2 and Figure 5 The guide rail type electric energy meter installation structure provided in the present application includes a bottom shell 1 and a buckle 2. The outer side of the bottom shell 1 is provided with a guide rail installation groove 11 and a buckle installation groove 12 which are interconnected. The guide rail installation groove 11 is used to be clamped with the guide rail 3 so as to clamp the electric energy meter on the guide rail 3. The buckle 2 is provided on one side of the guide rail installation groove 11 in the width direction, and the buckle 2 is installed through the buckle installation groove 12. The buckle 2 includes an integrally formed head 21 and an elastic telescopic portion 22. The head 21 is closer to the guide rail installation groove 11 than the elastic telescopic portion 22. The head 21 is used to abut the guide rail 3. The elastic telescopic portion 22 is used to provide the head 21 with an elastic extrusion force toward the guide rail 3, and enables the head 21 to move away from or toward the guide rail installation groove 11.

[0050] Please combine Figure 2 and Figure 5 In the present application, the bottom shell 1 can provide physical protection for the electronic components inside the electric energy meter, prevent external environmental factors (such as dust and moisture) from damaging the internal electronic components, and ensure the stable operation of the electric energy meter. The outer side of the bottom shell 1 is the surface of the bottom shell 1 exposed to the external environment. As mentioned above, the outer shell of the guide rail type electric energy meter includes a bottom shell 1 and a shell cover. The space between the shell cover and the bottom shell 1 is used to install electronic components. Some logos and display screens are usually set on the shell cover. The outer side of the bottom shell 1 can be the outer surface of the bottom shell 1 opposite to the shell cover.

[0051] Please combine Figure 3 , Figure 4 and Figure 5 Generally speaking, the width of the guide rail installation groove 11 provided on the bottom shell 1 is greater than the width of the guide rail 3 to be assembled. In the initial state of the buckle 2, the head 21 of the buckle 2 will extend into the guide rail installation groove 11, causing the opening width of the guide rail installation groove 11 to become narrower.

[0052] Please continue to refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 , from the direction shown in the figure, when the guide rail type energy meter is clamped on the guide rail 3, the guide rail type energy meter is hung on the guide rail 3 through the guide rail installation groove 11 along the width direction away from the groove wall of the buckle 2. At this time, the guide rail type energy meter has not been completely clamped on the guide rail. After that, it is necessary to squeeze the buckle 2 by external force to move the head 21 of the buckle 2 in the direction away from the guide rail installation groove 11, and the opening width of the guide rail installation groove 11 gradually widens. Finally, the guide rail 3 can enter the guide rail installation groove 11, and the head 21 of the buckle is pressed against the guide rail 3 under the extrusion of the elastic force of the elastic telescopic part 22, so as to keep the guide rail type energy meter firmly clamped on the guide rail 3.

[0053] When the rail-type electric energy meter is removed from the rail 3, the elastic expansion part 22 is pressed by external force to move the head 21 of the buckle 2 in a direction away from the rail mounting groove 11, and the opening width of the rail mounting groove 11 becomes wider, so that the rail-type electric energy meter can be removed from the rail 3. Afterwards, the head 21 of the buckle 2 moves toward the rail mounting groove 11 under the elastic force of the elastic expansion part 22, and the buckle 2 returns to the initial state.

[0054] In summary, in the installation process of the guide rail type electric energy meter of the present application, the opening width of the guide rail installation slot 11 gradually widens by squeezing the elastic telescopic portion 22 of the buckle 2 with external force, and finally the guide rail 3 can enter the guide rail installation slot 11, and the head 21 of the buckle 2 abuts against the guide rail 3 under the action of the elastic force of the elastic telescopic portion 22. Since the opening width of the guide rail installation slot 11 gradually widens during the installation of the electric energy meter, and after the installation, the head 21 of the buckle 2 abuts against the guide rail 3 under the action of the elastic force of the elastic telescopic portion 22, the guide rail type electric energy meter installation structure of the present application can be installed with a guide rail with a larger size or a guide rail with a smaller size, and has a good tolerance for the size deviation of the guide rail, which can improve the matching degree between the guide rail type electric energy meter and the guide rail, so that the guide rail type electric energy meter can be stably installed on the guide rail.

[0055] In addition, the buckle 2 used in the guide rail type electric energy meter installation structure of the present application includes an integrally formed head 21 and an elastic telescopic portion 22. Compared with the existing buckle composed of at least two independent components, it has the characteristics of simple composition and convenient installation.

[0056] It should be noted that in some embodiments of the present application, a limiting structure such as a limiting recess 112 can be formed on the groove wall of the guide rail mounting groove 11 away from the buckle 2 in the width direction, so that the guide rail type electric energy meter can be hung on the guide rail 3 more stably, facilitating the installation of the guide rail type electric energy meter.

[0057] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 In one embodiment of the present application, the head 21 includes a contact surface 211. Along the depth direction of the guide rail mounting groove 11, the contact surface 211 is located on the side of the head 21 close to the bottom surface 111 of the guide rail mounting groove, and there is a distance between the contact surface 211 and the bottom surface 111 of the guide rail mounting groove, forming a slot for the guide rail 3.

[0058] Please continue to refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 The head 21 includes a contact surface 211, and the contact surface 211 and the bottom surface 111 of the guide rail mounting groove form a guide rail slot. During the installation process of the guide rail type electric energy meter and the guide rail 3, one end of the guide rail 3 can be inserted into the slot. The slot has a certain limiting effect on the guide rail 3, which can prevent the guide rail 3 from escaping from the depth direction of the guide rail mounting groove 11, thereby improving the installation stability of the guide rail type electric energy meter and the guide rail 3.

[0059] Please continue to refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 In some embodiments of the present application, the abutment surface 211 is a plane parallel to the bottom surface 111 of the guide rail mounting groove.

[0060] Specifically, in some embodiments of the present application, the surface where the guide rail 3 contacts the head 21 of the buckle 2 is usually an inclined surface, and the abutment surface 211 between the head 21 and the guide rail 3 is set to a plane parallel to the bottom surface 111 of the guide rail mounting groove, which helps the buckle 2 to apply an extrusion force to the guide rail 3 in the width direction of the guide rail 3, so that the guide rail-type electric energy meter can be stably connected to the guide rail 3.

[0061] It is understandable that the portion where the head 21 contacts the guide rail 3 may have other shapes and structures. For example, the engaging surface 111 may be an inclined surface or an arc surface, and the present application does not impose any limitation on this.

[0062] Please continue to refer to Figure 2 , Figure 3 , Figure 4 and Figure 5 In some embodiments of the present application, the head 21 also includes a sliding surface 212. Along the depth direction of the guide rail mounting groove 11, the sliding surface 212 is located on the side of the head 21 away from the bottom surface 111 of the guide rail mounting groove, and the sliding surface 212 is an inclined surface inclined relative to the bottom surface 111 of the guide rail mounting groove.

[0063] For more details, please refer to Figures 2 to 5When the guide rail type electric energy meter is clamped to the guide rail 3, the upper end of the guide rail type electric energy meter is hung on the upper end of the guide rail 3 through the groove wall on one side of the width direction of the guide rail installation groove 11. At this time, the lower end of the guide rail type electric energy meter (i.e., the end where the buckle 2 is set) is still outside the guide rail 3. Figure 3 From the current orientation shown, the sliding surface 212 of the buckle head 21 is located on the left side of the lower end of the guide rail 3. When the lower end of the guide rail type energy meter is pressed toward the guide rail 3, the lower end of the guide rail 3 will slide along the sliding surface 212 into the guide rail mounting groove 11.

[0064] It can be seen from the above process that, since the head 21 of the buckle 2 is provided with the sliding surface 212 , the rail-type electric energy meter can be mounted on the rail 3 more easily and with less effort.

[0065] Figure 6 for Figure 4 The three-dimensional structural schematic diagram of the clip in the guide rail type electric energy meter installation structure is shown. Figure 7 for Figure 4 A side view of the clip in the rail-type electric energy meter installation structure is shown. Figure 8 for Figure 4 The three-dimensional structural diagram of the bottom shell 1 in the guide rail type electric energy meter installation structure is shown. Fig. 9 for Figure 4 The bottom view of the bottom shell 1 in the guide rail type electric energy meter installation structure is shown.

[0066] Please combine Figures 4 to 9 In some embodiments of the present application, the head 21 further includes a positioning surface 213. The positioning surface 213 is the bottom surface of the card slot along the width direction of the guide rail mounting slot 11. The buckle mounting slot 12 has a positioning wall 121. The positioning wall 121 can abut against the positioning surface 213 to prevent the buckle 2 from falling out of the buckle mounting slot 12.

[0067] Specifically, the guide rail mounting groove 11 and the buckle mounting groove 12 are connected, and the buckle 2 is installed in the buckle mounting groove 12. In order to prevent the buckle 2 from escaping from the buckle mounting groove 12 and falling from the guide rail mounting groove 11. The head 21 of the buckle of the present application is provided with a positioning surface 213, and correspondingly, a positioning wall 121 is provided at the buckle mounting groove 12. Before the guide rail type electric energy meter is installed with the guide rail 3, the buckle 2 is installed at the buckle mounting groove 12, and the positioning surface 213 of the buckle head 21 abuts against the positioning wall 121 at the buckle mounting groove 12, so that the buckle 2 can be prevented from escaping from the buckle mounting groove 12 and the buckle 2 can be prevented from falling.

[0068] It should be noted that although Figure 5In the structure shown, the positioning wall 121 is a straight wall, and the positioning surface 213 of the buckle is a plane. However, the structural form of the positioning wall 121 of the buckle installation groove 12 and the positioning surface 213 of the buckle in the present application is not limited to a plane, for example, it can also be a curved surface, a serrated surface, etc., and the present application does not limit this.

[0069] Please continue to refer to Figures 5 to 9 In some embodiments of the present application, the elastic telescopic portion 22 is wavy, one end of the elastic telescopic portion 22 is fixedly connected to the head 21, and the other end of the elastic telescopic portion 22 is a free end. A boss 122 is provided in the buckle installation groove 12 to abut against the free end.

[0070] For more information, see Figure 6 and Figure 7 The elastic telescopic portion 22 of the present application is wavy in shape, and the wavy elastic telescopic portion 22 can meet the requirements of the buckle 2 for telescopic amount and elastic force, and the wavy elastic telescopic portion 22 can be integrally injection molded with the head 21 for easy processing.

[0071] Please combine Figure 5 , Figure 8 and Fig. 9 The buckle installation groove 12 is provided with a boss 122 that abuts against the free end. In this way, when the rail-type electric energy meter is installed, the buckle 2 moves in a direction away from the rail installation groove 11, and the free end of the elastic telescopic part 22 abuts against the boss 122. The elastic telescopic part 22 is compressed, and elastic potential energy is accumulated. When the rail-type electric energy meter is clamped on the rail 3, the elastic telescopic part 22 has a rebound effect, pressing the buckle head 21 toward the rail 3 to continuously ensure that the rail-type electric energy meter and the rail 3 are firmly clamped.

[0072] In addition, please continue to refer to Figure 5 , Figure 8 and Fig. 9 , along the width direction of the guide rail installation groove 11, the end of the buckle installation groove 12 close to the guide rail installation groove 11 is provided with a positioning wall 121, and the end of the buckle installation groove 12 away from the guide rail installation groove 11 is provided with a boss 122. The positioning wall 121 and the boss 122 constitute a positioning structure of the buckle installation groove 12 along the width direction of the guide rail installation groove 11. Specifically, before the guide rail type electric energy meter installation structure is clamped with the guide rail 3, the buckle 2 is in the initial state. At this time, Figure 5 The positioning surface 213 of the head 21 of the middle buckle 2 will fit with the positioning wall 121 of the buckle installation groove 12, and the lower end of the elastic telescopic part 22 of the buckle 2 will contact the boss 122, which helps to improve the stability of the buckle 2 in the buckle installation groove 12.

[0073] Please continue to refer to Figure 6 and Figure 7In some embodiments of the present application, the buckle 2 also includes a positioning portion, and the positioning portion includes a first positioning portion 23 and a second positioning portion 24 that are connected to each other. The first positioning portion 23 is fixedly connected to the head 21, and the second positioning portion 24 is located at an end of the first positioning portion 23 away from the head 21. Along the depth direction of the guide rail mounting groove 11, the first positioning portion 23 includes a first surface 231 and a second surface 232 that are relatively arranged, and the second positioning portion 24 includes a third surface 241 and a fourth surface 242 that are relatively arranged. The first surface 231 and the third surface 241 are located on the same side of the positioning portion, and the second surface 232 and the fourth surface 242 are located on the same side of the positioning portion. There is a height difference between the first surface 231 and the third surface 241. The second surface 232 is provided with an avoidance notch 233 relative to the fourth surface 242 to facilitate the buckle 2 to be installed into the buckle mounting groove 12. Please refer to Figure 5 and Figure 8 Along the depth direction of the guide rail mounting groove 11 , the buckle mounting groove 12 includes a first groove wall 123 and a second groove wall 124 that are arranged opposite to each other, the first surface 231 abuts against the first groove wall 123 , and the fourth surface 242 abuts against the second groove wall 124 .

[0074] Please combine Figure 5 , Figure 6 , Figure 7 and Figure 8 When the buckle 2 is installed, the second positioning portion 24 first enters the buckle installation groove 12, and the fourth surface 242 abuts against the second groove wall 124. Then, the first positioning portion 23 enters the buckle installation groove 12, and the first surface 231 of the first positioning portion 23 abuts against the first groove wall 123. In this way, the position of the buckle 2 in the buckle installation groove 12 is determined along the depth direction of the guide rail installation groove 11, which helps to determine the clamping position of the buckle 2 and the guide rail 3 and reduce the phenomenon of clamping deviation or unstable clamping.

[0075] It should be noted that, since the first surface 231 needs to abut against the first groove wall 123, and the fourth surface 242 needs to abut against the second groove wall 124, therefore, along the depth direction of the guide rail installation groove 11, the buckle 2 is in a natural state, and the distance between the first surface 231 and the fourth surface 242 is slightly greater than the distance between the first groove wall 123 and the second groove wall 124. During the installation process of the buckle 2, the first positioning portion 23 will deform to a certain extent relative to the second positioning portion 24. The setting of the avoidance notch 233 and the setting of the height difference between the first surface 231 and the third surface 241 are both to enable the buckle 2 to smoothly enter the buckle installation groove 12, and to achieve the effect that the first surface 231 abuts against the first groove wall 123, and the fourth surface 242 abuts against the second groove wall 124.

[0076] Please continue to refer to Figure 6 and Figure 7In some embodiments of the present application, the positioning portion further includes a guide surface 251. The guide surface 251 is connected between the first surface 231 and the third surface 241, so that the third surface 241 smoothly transitions to the first surface 231.

[0077] Please combine Figure 5 , Figure 6 , Figure 7 and Figure 8 In some embodiments of the present application, there is a height difference between the first surface 231 of the first positioning portion 23 and the third positioning surface 213 of the second positioning portion 24, and a guide surface 251 is provided between the first surface 231 and the third surface 241. In this way, when the buckle 2 is installed, the second positioning portion 24 first enters the buckle installation groove 12, and the first positioning portion 23 can slide smoothly into the buckle installation groove 12 along the guide surface 251 under the guidance of the guide surface 251. The provision of the guide surface 251 makes the installation of the buckle 2 easier.

[0078] Please continue to refer to Figure 6 and Figure 7 In some embodiments of the present application, the number of the positioning portions is two, and the two positioning portions are located on both sides of the elastic telescopic portion 22 in the width direction.

[0079] Specifically, the positioning portion and the elastic telescopic portion 22 are both connected to the head 21, and the elastic telescopic portion 22 provides elastic force for the head 21. In some embodiments of the present application, the two positioning portions are arranged on both sides of the elastic telescopic portion 22 in the width direction, so that the elastic force of the elastic telescopic portion 22 acts on the middle position of the width direction of the head 21, which helps the head 21 to stably contact with the guide rail 3 and improves the clamping stability. In addition, the two positioning portions are located on both sides of the elastic telescopic portion 22 in the width direction, which can better position the buckle 2 when the buckle 2 is installed.

[0080] Please combine Figure 5 , Figure 6 and Figure 8 In some embodiments of the present application, along the depth direction of the guide rail installation groove 11, the elastic telescopic portion 22 includes a first side and a second side opposite to each other, and the first side is close to the second groove wall 124. The second side is opposite to the first groove wall 123, and a notch is provided at the first groove wall 123 to expose the elastic telescopic portion 22. In this way, the elastic telescopic portion 22 is not interfered by the first groove wall 123 and the second groove wall 124 during the telescopic process.

[0081] Furthermore, since the first groove wall 123 is provided with a notch exposing the elastic telescopic portion 22, the elastic telescopic portion 22 may not be interfered with by the first groove wall 123 and the second groove wall 124 during the telescopic process. Therefore, in the depth direction of the guide rail mounting groove 11, the distance between the first side and the second side of the elastic telescopic portion 22 may be greater than the distance between the first groove wall 123 or the first groove wall 123. The larger the distance between the first side and the second side of the elastic telescopic portion 22, the better the elasticity and strength, which helps to improve the compression stability of the buckle 2 on the guide rail 3.

[0082] Please refer to Figure 1 , Figure 4 and Figure 6 In some embodiments of the present application, the buckle 2 also includes a tail portion 26, which is connected to an end of the positioning portion away from the head portion 21, and the tail portion 26 is provided with a tool hole 261, which is exposed on the outside of the bottom shell 1.

[0083] As mentioned above, when removing the rail-type electric energy meter from the rail 3, it is necessary to squeeze the buckle 2 by external force, so that the head 21 of the buckle 2 moves in the direction away from the rail mounting groove 11, and the opening width of the rail mounting groove 11 becomes wider, so that the rail-type electric energy meter can be taken out from the rail 3. In some embodiments of the present application, the buckle 2 includes a tail 26 connected to the end of the positioning portion away from the head 21, and the tail 26 is provided with a tool hole 261, and the tool hole 261 is exposed on the outside of the bottom shell 1. In this way, when disassembling, a screwdriver can be inserted into the tool hole 261 to squeeze the buckle 2 downward to separate the buckle 2 from the rail 3, and the rail-type electric energy meter can be removed.
