[0028] The following is an explanation and description of the technical solutions of the embodiments of the present invention in conjunction with the drawings of the embodiments of the present invention, but the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0029] In the following description, terms such as "inside", "outside", "up", "down", "left", "right", etc. that indicate directions or positional relationships are only used to facilitate the description of the embodiments and simplify the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present invention.

[0030] This embodiment provides a guide rail type electric energy meter that is easy to disassemble and assemble, including an electric energy meter body 2, a guide rail groove 21 is provided on the back of the electric energy meter, and a clamping strip 211 for clamping the upper end of the guide rail 1 is provided on the upper end of the guide rail groove 21. Figure 1 To the attached Figure 3 The guide rail type electric energy meter can at least include a sliding clamp 3, the middle part of the sliding clamp 3 is hollowed out, the inner edge of the sliding clamp 3 is provided with an elastic convex pin 31, the top of the elastic convex pin 31 is fixedly connected to the back of the electric energy meter, and a slide groove 22 is provided on the back of the electric energy meter. The slide groove 22 is located below the guide rail groove 21, the outer edge of the sliding clamp 3 is slidably connected to the slide groove 22, the top of the sliding clamp 3 is used to clamp the lower end of the guide rail 1, and the bottom of the sliding clamp 3 protrudes from the bottom of the electric energy meter.

[0031] It can be understood that the elastic convex pin 31 is made of elastic material as a whole, the top of the elastic convex pin 31 is fixedly connected to the back of the electricity meter, and the bottom end of the elastic convex pin 31 is fixedly connected to the inner edge of the sliding clamp 3. The elastic convex pin 31 can extend to a certain length during the sliding of the sliding clamp 3 and gradually recover to its original length during the resetting of the sliding clamp 3. In this way, the sliding clamp 3 is fixed to the back of the electricity meter while the sliding clamp 3 is "sliding down-resettling" to engage the guide rail 1, thereby ensuring the stability of the guide rail type electricity meter during installation or disassembly on the guide rail 1.

[0032] In this embodiment, a sliding clamp 3 is designed on the back of the guide rail type electricity meter, and an elastic protruding pin 31 is provided on the inner edge of the sliding clamp 3 and the top of the elastic protruding pin 31 is fixedly connected to the back of the electricity meter to ensure the stability of the guide rail type electricity meter when it is installed or removed on the guide rail 1. The outer edge of the sliding clamp 3 is slidably connected to the slide groove 22, which provides a guiding effect during the process of the sliding clamp 3 "sliding down and resetting" to connect the guide rail 1, so that the sliding of the sliding clamp 3 is smoother. At the same time, the design of the bottom of the sliding clamp 3 protruding from the bottom of the electricity meter enables the operator to remove and install the electricity meter on the guide rail 1 by pulling down the part of the bottom of the sliding clamp 3 protruding from the bottom of the electricity meter on the front of the electricity meter, overcoming the inconvenience caused by limited space to the operator in disassembling and installing the electricity meter, and improving the disassembly and assembly efficiency.

[0033] In one embodiment of this specification, please refer to the attached Figure 2 To the attached Figure 6 There are at least two elastic protrusions 31, and the elastic protrusions 31 are respectively arranged on the left and right sides of the inner edge of the sliding clamp 3. A boss 311 is provided at the top of the elastic protrusion 31, and a first groove 23 is provided on the back of the electric energy meter. The boss 311 matches the first groove 23, and the boss 311 is fixedly installed in the first groove 23.

[0034] In this embodiment, the elastic protrusions 31 are arranged on the left and right sides of the inner edge of the sliding clamp 3 and the boss 311 at the top of the elastic protrusion 31 is fixedly connected to the first groove 23 on the back of the electric energy meter. This design can effectively prevent the sliding clamp 3 from accidentally falling off during the sliding process and the elastic amplitude from being too large when sliding up and down, thereby improving the stability of the sliding clamp 3 when clamping the guide rail 1.

[0035] On the other hand, in this embodiment, the first groove 23 is provided with a slope in the direction away from the guide rail groove 21, which helps to better adapt to the deformation of the top boss 311 of the elastic convex pin 31 during the process of pulling down the sliding clip 3 to remove the guide rail 1, thereby improving the reliability of the guide rail type electricity meter during disassembly to a certain extent.

[0036] In one embodiment of this specification, please refer to the attached Figure 5 To the attached Figure 7 A positioning member 32 is provided on the top of the sliding clamping member 3. The cross section of the positioning member 32 is a right triangle, and the hypotenuse in the cross section of the positioning member 32 is arranged in a direction away from the back of the electric energy meter.

[0037] When the locking cam 31 is in the unlock state, the locking cam 31 is automatically retracted to the left by the locking cam 32, so that the locking cam 31 is locked in the unlock state.

[0038] The setting of the top clamping member 32 of the sliding clamping member 3 in this embodiment makes it possible for the operator to install the entire guide rail type electricity meter on the guide rail 1 without manually operating the sliding clamping member 3, and without observing how to adjust the sliding clamping member 3 in the narrow space between the back of the electricity meter and the wall to achieve the installation of the guide rail type electricity meter on the guide rail 1. The operator can install the electricity meter on the guide rail 1 through the squeezing effect between the lower end of the guide rail 1 and the sliding clamping member 3 on the front of the electricity meter, which greatly improves the disassembly and assembly efficiency.

[0039] On the other hand, in this embodiment, the connection between the hypotenuse in the cross section of the retaining member 32 and the other two sides is designed to be a smooth arc, so that the process of the lower end of the guide rail 1 moving along the side of the hypotenuse in the retaining member 32 toward the back of the electricity meter is smoother.

[0040] In one embodiment of this specification, please refer to the attached Figure 7 , the top sides of the sliding clamp 3 are provided with outwardly protruding first fixing members 33, which are used to abut against the lower end of the guide rail 1 after the electric energy meter is installed on the guide rail 1, and help the sliding clamp 3 to further fix the guide rail 1 after the guide rail 1 is installed in the guide rail groove 21. Please refer to the attached Figure 4 , the upper ends of the chute 22 are provided with first abutment members 221 protruding inwards, see the attached Figure 3 The upper surface of the first fixing member 33 abuts against the lower surface of the first abutting member 221 , which helps to improve the stability of the sliding clamping member 3 when fixing the guide rail 1 .

[0041] On the other hand, in this embodiment, outwardly protruding second fixing members 34 are provided on both sides of the sliding clamp 3, and inwardly protruding second abutting members 222 are provided on both sides of the upper end of the slide groove 22. The upper surface of the second fixing member 34 abuts against the lower surface of the second abutting member 222, thereby further improving the stability of the sliding clamp 3 when fixing the guide rail 1.

[0042] On the other hand, in this embodiment, a limiting member 35 is provided in the middle of the sliding clamp 3, and the limiting member 35 protrudes toward the back of the electric energy meter. A second groove 24 is provided on the back of the electric energy meter. The second groove 24 is used to limit the up and down movement range of the limiting member 35, so that the sliding clamp 3 is not only limited by the extension length of the elastic protruding pin 31 during the up and down sliding process, but also by the corresponding length distance of the second groove 24, which further improves the stability of the sliding clamp 3 when realizing the disassembly and assembly of the guide rail type electric energy meter.

[0043] On the other hand, in this embodiment, a hand-pull piece 36 is provided at the bottom of the sliding clamp 3, and the hand-pull piece 36 is located at the part of the sliding clamp 3 protruding from the bottom of the electric energy meter, so that the process of removing the guide rail type electric energy meter from the guide rail 1 only requires the operator to pull down the hand-pull piece 36 on the front of the electric energy meter.

[0044] For example, the disassembly and assembly principles and steps of a rail-type electric energy meter that is easy to disassemble and assemble provided in multiple embodiments of this specification are as follows:

[0045] (1) Installation of rail-type electric energy meter on rail 1:

[0046] First, clamp the clamping strip 211 of the guide rail groove 21 on the back of the electric energy meter to the upper end of the guide rail 1, and slide the electric energy meter along the guide rail 1 to a suitable working position;

[0047] When the guide rail 1 is in the state of being moved up and down, the guide rail 1 is moved to the state of being moved down by the guide rail 1, and the guide rail 1 is moved to the state of being moved down by the guide rail 1. When the guide rail 1 is in the state of being moved up and down, the guide rail 1 is moved to the state of being moved down by the guide rail 1, and the guide rail 1 is moved to the state of being moved down by the guide rail 1.

[0048] (2) Removal of the rail-type electric energy meter from the rail 1:

[0049] First, the operator pulls down the hand-pull member 36 protruding from the bottom of the meter on the front. The elastic protrusion 31 of the sliding clamp 3 extends under the action of the pulling force, and the sliding clamp 3 slides down along the slide groove 22, thereby releasing the clamping of the side of the other right-angled side of the clamp 32 from the lower end of the guide rail 1.

[0050] Then, move the lower end of the electricity meter away from the lower end of the guide rail 1, and at the same time slightly lift the electricity meter upward to release the clamping connection between the clamping bar 211 of the guide rail groove 21 on the back of the electricity meter and the upper end of the guide rail 1, completing the removal of the guide rail type electricity meter from the guide rail 1.

[0051] It can be seen that whether it is the installation of the guide rail type electricity meter on the guide rail 1 or the removal of the guide rail type electricity meter from the guide rail 1, the easy-to-disassemble guide rail type electricity meter provided by the embodiment of this specification can avoid the operator's need to manually operate the disassembly and assembly parts in the narrow space between the back of the electricity meter and the wall, so that the operator can realize the disassembly and installation of the electricity meter on the guide rail 1 on the front of the electricity meter, which brings convenience to the operator in disassembling and installing the electricity meter and greatly improves the disassembly and assembly efficiency.

[0052] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Those skilled in the art will understand that the present invention includes, but is not limited to, the contents described in the accompanying drawings and the above specific embodiments.
