Description

Technical Field

[0001] This utility model relates to the field of electricity meter installation technology, and specifically to electricity meter installation structure. Background Technology

[0002] Modern electricity meters, in addition to basic electricity measurement functions, integrate various intelligent features such as remote data transmission and fault detection, greatly facilitating power management and user services. However, despite the increasingly sophisticated functions of electricity meters, there are still many shortcomings in their installation structure.

[0003] Currently, most electricity meters on the market are installed using screws. While this method ensures the meter's stability, it also presents inconvenience for installation and removal. Each time an electricity meter is installed or replaced, a professional technician must use screwdrivers and other tools to tighten or loosen each screw. This not only increases installation time and labor intensity but is also particularly difficult to perform in confined spaces. This installation method is especially inconvenient when frequent meter replacements or repairs are required, severely impacting work efficiency and user experience.

[0004] Therefore, this application proposes an electricity meter installation structure to solve the above-mentioned technical problems. Utility Model Content

[0005] The main purpose of this utility model is to overcome the above-mentioned shortcomings and provide an electricity meter installation structure that does not require the use of screws and is easy to install and disassemble.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] An electricity meter mounting structure includes: multiple insert assemblies fixedly mounted on the back of the electricity meter, each insert assembly comprising a hollow cylinder with an open end and multiple spring pin assemblies surrounding the open end of the cylinder; a positioning mounting bracket for fixing the electricity meter on the mounting surface; and multiple plug assemblies fixedly mounted on the positioning mounting bracket and correspondingly inserted into each of the multiple insert assemblies, each plug assembly comprising a fixing plate, a connecting shaft vertically mounted on the fixing plate, an abutment post fixedly mounted on the end of the connecting shaft, and a hemispherical pin fixedly mounted on the end of the abutment post.

[0008] Furthermore, the spring pin assembly includes a housing fixedly disposed on the outer wall of the end of the cylinder, a wedge-shaped pin movably inserted into the housing and penetrating the outer wall of the cylinder, and a first spring having one end fixedly connected to the wedge-shaped pin and the other end fixedly connected to the inner cavity of the housing.

[0009] Furthermore, the insert assembly also includes a double-conical slider that slides through the connecting shaft and is located between the abutment post and the fixing plate, a retaining ring that is fixedly disposed on the connecting shaft and is located between the double-conical slider and the fixing plate, and a conical groove formed at the end of the abutment post facing the double-conical slider for inserting the double-conical slider.

[0010] Furthermore, the insert assembly also includes a second spring fixedly disposed at one end of the inner cavity of the cylinder and a top block fixedly disposed at the movable end of the second spring for abutting the hemispherical pin.

[0011] Furthermore, an arc groove is formed on the contact surface between the top block and the hemispherical pin head, and the arc groove fits into the spherical outer wall of the hemispherical pin head.

[0012] Furthermore, it also includes multiple limiting components fixedly mounted on the positioning mounting frame. There are four limiting components in total, which are symmetrically arranged on the upper and lower sides and the left and right sides of the positioning mounting frame, including a mounting plate fixedly connected to the positioning mounting frame and a limiting guide plate fixedly mounted on the mounting plate.

[0013] The beneficial effects of this utility model are reflected in:

[0014] During installation, this utility model only requires aligning the insert assembly on the back of the electricity meter with the plug assembly on the positioning mounting bracket and pushing the electricity meter to engage the spring pin assembly with the abutment post, thereby achieving the insertion of the insert assembly and the plug assembly and the installation and fixation of the electricity meter. During removal, the electricity meter is pushed and pulled back again to release the obstruction of the abutment post on the wedge-shaped pin head, thereby removing the insert assembly, the plug assembly, and the electricity meter. Compared with the original screw-fixed installation method, this greatly improves the convenience of electricity meter installation and removal. Attached Figure Description

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] like Figure 1-7 As shown, this utility model provides an electricity meter installation structure, including:

[0026] Multiple insert assemblies 2 are fixedly mounted on the back of the energy meter 1. Each insert assembly 2 includes a hollow cylinder 21 with an open end and multiple spring pin assemblies 22 surrounding the open end of the cylinder 21. A positioning mounting bracket 3 is used to fix the energy meter 1 on the installation surface. Multiple insert post assemblies 4 are fixedly mounted on the positioning mounting bracket 3 and are inserted into each of the multiple insert assemblies 2. Each insert post assembly 4 includes a fixing plate 41, a connecting shaft 42 vertically mounted on the fixing plate 41, an abutment post 43 fixedly mounted on the end of the connecting shaft 42, and a hemispherical pin head 44 fixedly mounted on the end of the abutment post 43. The spring pin assembly 22 includes a housing 221 fixedly mounted on the outer wall of the end of the cylinder 21, a wedge-shaped pin head 222 movably inserted into the housing 221 and penetrating the outer wall of the cylinder 21, and a first spring 223 with one end fixedly connected to the wedge-shaped pin head 222 and the other end fixedly connected to the inner cavity of the housing 221. The insert assembly 4 also includes a double-conical slider 45 that slides through the connecting shaft 42 and is located between the abutment post 43 and the fixing plate 41, a retaining ring 46 that is fixedly disposed on the connecting shaft 42 and is located between the double-conical slider 45 and the fixing plate 41, and a conical groove 47 formed at the end of the abutment post 43 facing the double-conical slider 45 for inserting the double-conical slider 45.

[0027] During installation, the positioning mounting bracket 3 is first fixed to the surface of the electricity meter 1 to be installed with screws. Then, the plug assembly 2 on the back of the electricity meter 1 is aligned with the plug assembly 4 on the positioning mounting bracket 3. The electricity meter 1 is moved so that the plug assembly 4 is inserted into the plug assembly 2. During the insertion process, the inclined surface of the wedge pin 222 first abuts against the hemispherical pin 44. Under the pushing force of the hemispherical pin 44, the wedge pin 222 compresses the first spring 223 and retracts into the housing 221. When the wedge pin 222 slides past the end of the abutment post 43, it loses its blocking effect. The first spring 223 returns to its original position and extends, causing the wedge pin 222 to extend out of the housing 221. At this time, the vertical surface of the wedge pin 222 is stuck at the end of the abutment post 43, pulling the plug assembly 2. The plug assembly 2 cannot be separated from the plug assembly 4, thus realizing the installation of the electricity meter 1.

[0028] During dismantling, push the energy meter 1 towards the positioning mounting bracket 3. This causes the wedge pin 222 in the insert assembly 2 to first abut against one side of the conical surface of the double-conical slider 45. Due to the blocking effect of the retaining ring 46, the double-conical slider 45 cannot move towards the fixing plate 41. Therefore, the wedge pin 222 retracts into the housing 221 under the pushing force of the double-conical slider 45 and moves to the other side of the conical surface of the double-conical slider 45. At this time, pull back the energy meter 1, causing the wedge pin 222 in the insert assembly 2 to move in the opposite direction. The wedge pin 222 drives the double-conical slider 45 to insert into the conical groove 47. The wedge pin 222 slides along the other side of the conical surface of the double-conical slider 45 to the outer wall of the abutment post 43, thereby releasing the blocking effect of the abutment post 43 on the wedge pin 222. Continue to pull back the energy meter 1 to separate the insert assembly 2 from the insert post assembly 4, thus achieving the dismantling of the energy meter 1.

[0029] In summary, after the positioning mounting bracket 3 is installed, the installation and removal of the electricity meter 1 can be achieved simply by pushing and pulling, which is faster and more convenient than the original screw fixing method.

[0030] In one embodiment, the insert assembly 2 further includes a second spring 23 with one end fixedly disposed at the end of the inner cavity of the cylinder 21, and a top block 24 fixedly disposed at the movable end of the second spring 23 for abutting against the hemispherical pin head 44.

[0031] With this design, during the insertion process of the plug assembly 2 and the plug post assembly 4, the hemispherical pin head 44 presses against the top block 24, causing the second spring 23 to contract. When the thrust applied to the energy meter 1 is removed, the second spring 23 returns to its original position and pushes the plug assembly 2 to move in the opposite direction of the thrust along the direction of the thrust until the wedge-shaped pin head 222 in the spring pin assembly 22 abuts against the end of the abutment post 43. At this time, both ends of the whole consisting of the hemispherical pin head 44 and the abutment post 43 are abutted, making the insertion state of the plug assembly 2 and the plug post assembly 4 more stable, and the energy meter 1 is less likely to shake easily.

[0032] In one embodiment, an arc groove 5 is provided on the contact surface between the top block 24 and the hemispherical pin head 44, and the arc groove 5 is in contact with the spherical outer wall of the hemispherical pin head 44.

[0033] This design allows the top block 24 and the hemispherical pin head 44 to fit tightly together, improving the stability of the second spring 23 when it contracts.

[0034] In one embodiment, it also includes a plurality of limiting members 6 fixedly disposed on the positioning mounting frame 3. There are four limiting members 6 in total, which are symmetrically disposed on the upper and lower sides and the left and right sides of the positioning mounting frame 3, including a mounting plate 61 fixedly connected to the positioning mounting frame 3 and a limiting guide plate 62 fixedly disposed on the mounting plate 61.

[0035] Since the socket assembly 2 is on the back of the energy meter 1, it is difficult for the operator to align the socket assembly 2 with the plug assembly 4 when the view is obstructed during actual use. This design uses the limiting guide plate 62 to guide the insertion process of the socket assembly 2 and the plug assembly 4. The operator only needs to insert the energy meter 1 between the limiting guide plates 62, and the socket assembly 2 and the plug assembly 4 will be aligned, improving the convenience of use.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0037] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0038] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, "multiple" refers to two or more. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
