[0027] The utility model is further described below in conjunction with the accompanying drawings:

[0028] like Figure 1 - Figure 6 As shown, a guide rail type electric meter includes an electric meter body 1, a guide rail 2 and a wiring flap 4;

[0029] Among them, a rail groove 6 is provided on the bottom side of the electric meter body 1, and the guide rail 2 is inserted into the rail groove 6. A buckle limit buckle groove 5 is provided in the middle of the bottom groove wall of the rail groove 6. A plug-in and reset buckle 3 is installed in the buckle limit buckle groove 5. The top of the plug-in and reset buckle 3 is pressed on the edge of the guide rail 2, which is convenient for limiting the position of the electric meter body 1 relative to the guide rail 2 after the position is adjusted.

[0030] The wiring flap 4 is rotatably mounted on the front side of the meter body 1, and is mainly used to shield and protect the wiring terminal seat to prevent dust and water from accumulating.

[0031] like Figure 1 - Figure 6 As shown, the utility model also discloses the following more optimized specific structures:

[0032] In one embodiment, the top end of the plug-in and resetting buckle 3 is pressed against a side edge of the guide rail 2 .

[0033] The buckle limit buckle slot 5 consists of an insertion and unplugging through hole 51 and a limit slot 52 arranged on the top of the side hole wall of the insertion and unplugging through hole 51, and a spring stopper protrusion 53 extending toward the insertion and unplugging through hole 51 is integrally connected to the bottom slot wall 521 of the limit slot 52.

[0034] The plug-in and resetting buckle 3 is composed of a through-hole plug-in strip 31 and a pressing head 32 installed on the end side of the through-hole plug-in strip 31. A limiting frame 33 is integrally connected to the pressing head 32. A spring groove is provided in the limiting frame 33. A spring 34 is installed in the spring groove. The free length L0 of the spring 34 is greater than the length of the limiting frame 33.

[0035] In one embodiment, the crimping head 32 is located at one end of the plugging and resetting buckle 3 close to the guide rail strip 2. The crimping head 32 is provided with a first buckle portion 321 and a second buckle portion 322. In one embodiment, the first buckle portion 321 and the second buckle portion 322 are arranged in opposite directions, and the first buckle portion 321 and the second buckle portion 322 are respectively located below and above the crimping head 32. The buckle opening of the first buckle portion 321 faces one side edge of the guide rail strip 2, and the buckle opening of the second buckle portion 322 faces away from one side edge of the guide rail strip 2 and towards the top groove wall 522 of the limiting groove 52.

[0036] Among them, the first buckle portion 321 is used to crimp one side edge of the guide rail strip 2, and the second buckle portion 322 is used to clamp the top groove wall 522 for limiting when the through-hole plugging strip 31 is pulled outwards or externally.

[0037] In one embodiment, there are two second buckle portions 322, which are located on both sides of the limiting frame 33. There are two top groove walls 522, which are respectively arranged corresponding to the two second buckle portions 322.

[0038] In one embodiment, the bottom end of the spring 34 is pressed onto the spring stop bump 53, the limiting frame 33 is inserted into the limiting groove 52, the through-hole plugging strip 31 is inserted into the plugging through-hole 51, and the bottom end of the through-hole plugging strip 31 extends to the outside of the plugging through-hole 51. The bottom end of the through-hole plugging strip 31 serves as a handle 311. By pulling or externally pulling the handle 311 outwards, the through-hole plugging strip 31 can be driven to move outwards, so that the crimping head 32 is separated from the guide rail strip 2, and the electricity meter main body 1 slides and adjusts along the crimping guide rail strip 2. After the adjustment is completed, the through-hole plugging strip 31 is loosened, and the spring 34 drives the crimping head 32 to reset and stamping and crimping onto one side edge of the guide rail strip 2 to realize the stable positioning of the electricity meter main body 1. In one embodiment, the electricity meter main body 1 slides and adjusts along the crimping guide rail strip 2, which can be realized by applying a force in the same direction as the length direction of the guide rail strip 2 to the handle 311 to drive the movement of the electricity meter main body 1, or by directly applying a force in the same direction as the length direction of the guide rail strip 2 to the electricity meter main body 1.

[0039] In one embodiment, after the positions of the electricity meter main body 1 and the guide rail strip 2 are determined, the first buckle portion 321 crimps one side edge of the guide rail strip 2, and the bottom end (free end) of the spring 34 is pressed onto the spring stop bump 53 (at this time, the compression length of the spring 34 is the first compression length L1), so as to limit the electricity meter main body 1 and the guide rail strip 2. When the position of the electricity meter main body 1 needs to be adjusted, the through-hole plugging strip 31 can be pulled outwards or externally, so as to compress the spring 34 until the first buckle portion 321 is separated from one side edge of the guide rail strip 2 (at this time, the compression length of the spring 34 is the second compression length L2, L2 < L1 < L0), so that the crimping head 32 is separated from the guide rail strip 2, that is, the guide rail strip 2 is no longer restricted by the crimping head 32, so that the electricity meter main body 1 can slide on the crimping guide rail strip 2.

[0040] A flip mounting strip 13 is provided on the front side of the meter body 1, and crimping ears 7 are provided on both sides of the wiring flap 4. The crimping ears 7 are pressed onto the two ends of the flip mounting strip 13, and a boss 71 is provided on the inner side of the crimping ears 7. Rotation grooves are provided at both ends of the flip mounting strip 13, and the boss 71 is inserted into the rotation groove to realize rotation. In addition, the distance between the inner end sides of the two crimping ears 7 is slightly smaller than the length of the flip mounting strip 13, so that the crimping ears 7 are interference fit with the two end surfaces of the flip mounting strip 13 when rotating, and a certain pressure is generated to generate a large friction force. When the wiring flap 4 is flipped to any angle, the angle can be fixed without the help of external force, which is convenient for wiring.

[0041] In one embodiment, the electric meter body 1 is composed of a base 11 and an upper shell cover 12; the base 11 and the upper shell cover 12 are fastened together by shell fasteners 14 for easy disassembly.

[0042] like Figure 1 - Figure 6 In the guide rail type electric meter shown, the wiring flap 4 and the flip installation bar 13 are both plastic products (or other materials), so during the rotation process, a certain friction force is generated through interference fit to ensure that it can be flipped to any angle and will maintain its flipped state for a long time, which is convenient for the installation and removal of the wires; when the position of the electric meter body 1 needs to be adjusted, the plug-in reset buckle 3 (or handle 311) exposed at the bottom is pulled outward to make the clamping head 32 disengage from the guide rail bar 2, and then a force consistent with the length direction of the guide rail bar 2 is applied to the plug-in reset buckle 3, so that the electric meter body 1 slides along the guide rail bar 2, and the plug-in reset buckle 3 is released after sliding to the target position, so that it is reset under the action of the spring 34, and the position of the electric meter body 1 is fixed again; the guide rail type electric meter of the utility model can be operated with one hand and is easy to disassemble. Most of the structure of the plug-in reset buckle 3 is hidden in the base of the electric meter and is not easy to fall off.

The above-mentioned embodiments and the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements shall fall within the scope of the present invention to be protected.
