Description

Technical Field

[0001] This utility model relates to the field of wiring tools, and in particular to an auxiliary wiring tool for improving the safety and speed of meter replacement in metering operations. Background Technology

[0002] An electricity meter is an instrument used to measure electrical energy; it is also called a kilowatt-hour meter or energy meter. Its unit of measurement is kilowatt-hour (kW·h), which is commonly referred to as a "kilowatt-hour." For example, we need an electricity meter to calculate household electricity consumption in our daily lives. When we use various electrical appliances, such as lights, televisions, and refrigerators, the electricity meter records the total amount of electrical energy consumed by these appliances.

[0003] After prolonged use, electricity meters will show signs of aging. To ensure accurate electricity metering and safety, staff will replace the electricity meters. However, during the replacement process, the exposed wire ends can easily cause electric shock accidents and injuries. At the same time, the wiring sequence when connecting a new electricity meter can easily become confused, leading to wiring errors, abnormal metering, and safety hazards.

[0004] To address this issue, we propose an auxiliary wiring tool to improve the safety and speed of meter replacement during metering operations. Utility Model Content

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problems in the above or existing technologies, such as the risk of electric shock due to exposed wire ends during meter replacement and the occurrence of wiring sequence errors during the rewiring process after meter replacement, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide an auxiliary wiring tool for improving the safety and speed of meter replacement in metering operations.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an auxiliary wiring tool for improving the safety and speed of meter replacement in metering operations, comprising,

[0009] A plastic restraint mechanism includes a frame portion and a clamping portion disposed on the frame portion;

[0010] A plastic connecting mechanism, including a deformable part disposed on the frame portion;

[0011] A plastic fixing mechanism includes a clamping part disposed on the deformable part and a protective part disposed on the clamping part.

[0012] As a preferred embodiment of the auxiliary wiring tool for improving the safety and speed of meter replacement in this utility model, the deformable part includes a core wire, a spring sleeve disposed on the core wire, and a protective sleeve disposed on the spring sleeve.

[0013] As a preferred embodiment of the auxiliary wiring tool for improving the safety and speed of meter replacement in this utility model, the clamping part includes a side plate first disposed on the protective sleeve, a pressing member disposed on the side plate first, and a rotating plate first disposed on the side plate first.

[0014] As a preferred embodiment of the auxiliary wiring tool for improving the safety and speed of meter replacement in this utility model, the protective part includes a second side plate on the protective sleeve, a second rotating plate on the second side plate, a wire threading tube on the second rotating plate, a torsion spring on the wire threading tube, and a protective component on the second side plate.

[0015] As a preferred embodiment of the auxiliary wiring tool for improving the safety and speed of meter replacement in this utility model, the protective component includes an abutment plate disposed on the second side plate and a protective side plate disposed on the abutment plate.

[0016] As a preferred embodiment of this utility model for improving the safety and speed of meter replacement auxiliary wiring tools, the size of the protective sleeve is adapted to the inner diameter of the wire threading tube.

[0017] As a preferred embodiment of the auxiliary wiring tool for improving the safety and speed of meter replacement in this utility model, the inner wall of the contact plate is arc-shaped.

[0018] As a preferred embodiment of the auxiliary wiring tool for improving the safety and speed of meter replacement in this utility model, the extrusion component includes an arc-shaped plate disposed on a side plate, a clamping side plate disposed on the arc-shaped plate, and anti-slip teeth disposed on the clamping side plate.

[0019] As a preferred embodiment of the auxiliary wiring tool for improving the safety and speed of meter replacement in this utility model, the frame part includes a fixed frame and a through hole provided on the fixed frame.

[0020] As a preferred embodiment of the auxiliary wiring tool for improving the safety and speed of meter replacement in this utility model, the clamping part includes: a base disposed on a fixed frame and corresponding to the position of the through hole, an annular groove disposed on the base, a spring disposed inside the annular groove, a conical groove disposed on the base, an annular plate disposed inside the annular groove, an operating piece disposed on the annular plate, a reserved hole disposed on the operating piece, a compression flap disposed inside the conical groove, a splicing groove disposed on the compression flap, an elastic rope disposed on the compression flap, the upper end of the elastic rope being connected to the operating piece, and the spring being connected to the annular plate.

[0021] The beneficial effects of this utility model's auxiliary wiring tool for improving the safety and speed of meter replacement in metering operations are as follows: For three-phase three-wire and three-phase four-wire energy meters connected via current transformers, the wires are disconnected according to the order of the energy meter terminals. After each wire is disconnected, it is clamped with the corresponding plastic fixing mechanism. The protective side plate effectively blocks the exposed wire ends, preventing them from being exposed and reducing the risk of electric shock. In daily power operation environments, due to numerous complex factors, if wire ends are exposed without any protection, workers are very likely to touch these live wire ends during operation, leading to electric shock accidents. The proper protection of the protective side plate greatly reduces the occurrence of such electric shock risks. At the same time, it can fix the order of each wire connection, and when connecting a new energy meter, the wires are connected in the order of disconnection described above, avoiding metering abnormalities and other safety accidents caused by disordered wiring sequence. The various plastic fixing mechanisms are connected by a flexible plastic connecting mechanism, which facilitates operation. When replacing the meter, you only need to disconnect the circuit breaker at the output end of the electricity meter (user side) to ensure that there is no load at the electricity meter end, and then replace the meter according to the above procedure.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0033] Example 1, referring to Figure 1 This is the first embodiment of the present utility model. This embodiment provides an auxiliary wiring tool for improving the safety and speed of meter replacement in metering operations. It can protect exposed wire ends and clarify the wire sequence. It includes a plastic limiting mechanism 300, which includes a frame part 301 and a clamping part 302 disposed on the frame part 301.

[0034] The plastic connecting mechanism 200 includes a deformable part 201 disposed on the frame part 301;

[0035] The plastic fixing mechanism 100 includes a clamping part 101 disposed on the deformable part 201 and a protective part 102 disposed on the clamping part 101.

[0036] Furthermore, the deformable part 201 passes through the clamping part 302, and the clamping part 302 fixes the deformable part 201, thereby realizing the control of the length of the deformable part 201.

[0037] Specifically, the clamping plate 101 and the protective part 102 work together to clamp and protect the exposed wire ends. The structure, made entirely of plastic, has strong insulation, effectively preventing electric shock accidents caused by exposed wire ends. At the same time, it can orderly organize the wire sequence, preventing the wire ends from swinging freely and getting tangled, which could lead to connection errors during wiring. The plastic connecting mechanism 100 allows the plastic fixing mechanism 100 to be freely adjusted to adapt to various complex working environments. The frame part 301 of the plastic limiting mechanism 300 can provide stable support for the plastic connecting mechanism 200 and the plastic fixing mechanism 100, further improving safety.

[0038] Example 2, refer to Figure 3 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the deformable part 201 includes a core wire 201a, a spring sleeve 201b disposed on the core wire 201a, and a protective sleeve 201c disposed on the spring sleeve 201b.

[0039] Reference Figure 2 and Figure 4 The clamping plate 101 includes a side plate 101b disposed on the protective sleeve 201c, an extrusion member 101a disposed on the side plate 101b, and a rotating plate 101c disposed on the side plate 101b.

[0040] Reference Figure 5 The protective part 102 includes a second side plate 102a disposed on the protective sleeve 201c, a second rotating plate 102b disposed on the second side plate 102a, a threading tube 102c disposed on the second rotating plate 102b, a torsion spring 102d disposed on the threading tube 102c, and a protective member 102e disposed on the second side plate 102a.

[0041] Furthermore, rotating plate 101c is rotatably connected to the outside of threading tube 102c, rotating plate 202a and rotating plate 101c are in contact with each other, and the core wire 201a passes through threading tube 102c.

[0042] Furthermore, the torsion spring 102d is made of insulating material.

[0043] The protective component 102e includes an abutment plate 102e-1 disposed on the side plate 102a and a protective side plate 102e-2 disposed on the abutment plate 102e-1.

[0044] Furthermore, the height of the protective side plate 102e-2 is higher than that of the clamping side plate 101a-2, which can achieve more effective protection for the wire ends.

[0045] The size of the protective sleeve 201c is compatible with the inner diameter of the threading spool 102c.

[0046] The inner wall of the contact plate 102e-1 is arc-shaped.

[0047] Reference Figure 4 The extrusion member 101a includes an arc-shaped plate 101a-1 disposed on the side plate 101b, a clamping side plate 101a-2 disposed on the arc-shaped plate 101a-1, and anti-slip teeth 101a-3 disposed on the clamping side plate 101a-2.

[0048] During use, the operator applies pressure to squeeze side plate 101b and side plate 102a, opening the closed squeezing member 101a and protective member 102e. Then, the operator inserts the exposed wire end to be processed into the gap between the opened squeezing member 101a and protective member 102e. At this time, the clamping side plate 101a-2 on the squeezing member 101a and the contact plate 102e-1 on the protective member 102e work together. The clamping side plate 101a-2 gradually approaches the contact plate 102e-1 from one side, forming a clamping structure similar to pliers, firmly fixing the wire end and preventing it from shaking or shifting.

[0049] Most importantly, the protective side plate 102e-2 on the protective component 102e acts as a safety barrier. During wire insertion, it precisely controls the insertion depth, effectively preventing the wire from being partially exposed to the external environment due to excessive insertion. In complex electrical work sites, if the wire is exposed, nearby personnel, tools, or other conductive objects may accidentally touch it, causing an electric shock. The presence of the protective side plate 102e-2 greatly reduces this risk, effectively minimizing the possibility of electric shock.

[0050] Furthermore, the anti-slip teeth 101a-3 on the extrusion piece 101a also play an indispensable role. When the wire end is clamped between the clamping side plate 101a-2 and the contact plate 102e-1, the anti-slip teeth 101a-3 will tightly engage with the wire end, increasing the friction between them. This friction can effectively resist possible external pulling forces or vibrations, preventing the wire end from falling out of the clamping structure due to external interference. Once the wire end falls out, it may not only cause a break in the line connection affecting power transmission, but may also cause the wire end to swing freely inside the equipment, further increasing the risk of electric shock and equipment short circuits. The design of the anti-slip teeth 101a-3 further improves the safety and stability of the entire wire end fixing structure, providing a more reliable guarantee for the smooth operation of electrical work and personnel safety.

[0051] When it is necessary to adjust the position of the plastic fixing mechanism 100 on the plastic connecting mechanism 200, it is only necessary to pull the deformation part 201 at both ends. The spring sleeve 201b will be stretched and thinned by the pull, which will cause the core wire 201a to also be stretched and thinned, so that the deformation part 201 can move freely in the middle of the threading tube 102c. After the plastic fixing mechanism 100 slides to the appropriate position, the pull on the deformation part 201 is released, so that it returns to its original diameter, and the plastic fixing mechanism 100 is restricted again and no longer slides.

[0052] Example 3, referring to Figures 4-6 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the frame part 301 includes a fixing frame 301a and a through hole 301b disposed on the fixing frame 301a.

[0053] The clamping part 302 includes a base 302a disposed on the fixed frame 301a and corresponding to the position of the through hole 301b, an annular groove 302b disposed on the base 302a, a spring 302d disposed inside the annular groove 302b, a conical groove 302c disposed on the base 302a, an annular plate 302f disposed inside the annular groove 302b, an operating piece 302e disposed on the annular plate 302f, a reserved hole 302g disposed on the operating piece 302e, a compression flap 302h disposed inside the conical groove 302c, a splicing groove 302j disposed on the compression flap 302h, an elastic rope 302i disposed on the compression flap 302h, the upper end of the elastic rope 302i being connected to the operating piece 302e, and the spring 302d being connected to the annular plate 302f.

[0054] Furthermore, the base 302a is fixedly connected to the fixed frame 301a, and the core wire 201a passes through the through hole 301b, the size of which is adapted to the core wire 201a.

[0055] Furthermore, the annular plate 302f and the operating piece 302e form a whole and slide up and down inside the annular groove 302c. The size of the annular groove 302c is adapted to the annular plate 302f, which facilitates the movement of the annular plate 302f inside the annular groove 302c while avoiding the shaking of the annular plate 302f.

[0056] Furthermore, a conical structure is formed by assembling multiple extrusion petals 302h, and the splicing groove 302j forms a slot that allows the core wire 201a to pass through. The diameter of the slot is half that of the core wire 201a, and the core wire 201a is squeezed and clamped using the slot.

[0057] Furthermore, the inner diameter of the conical groove 302c is four-fifths of the conical structure formed by the splicing of the extrusion petals 302h. The slightly smaller inner diameter of the conical groove 302c can become increasingly tighter as the extrusion petals 302h move downwards, further enhancing the restriction effect on the core wire 201a.

[0058] Furthermore, the spring 302d is made of insulating material, and the spring 302d is in a contracted state under normal conditions. The contracted spring 302d can cause the annular plate 302f to press down on the compression petal 302h.

[0059] Furthermore, the elastic rope 302i is arranged at an angle from top to bottom and from outside to inside. When the operating piece 302e is pulled upward, the elastic rope 302i can pull the squeezing petal 302h upward and outward, releasing the restriction effect on the core wire 201a, without taking up too much space.

[0060] Furthermore, a support column can be provided in the middle of the fixing frame 301a to enhance its strength and prevent deformation of the fixing frame 301a. It can also be divided into zones according to A, B, C, and N, which helps to identify the plastic fixing mechanism 100 in each zone.

[0061] During use, after the operator clamps the wire end, in some special working environments, it is necessary to adjust the length of the deformable part 201. To do this, the operating plate 302e can be controlled to move upward, which, together with the annular plate 302f, drives the spring 302d to extend. The operating plate 302e pulls the squeezing valve 302h upward and outward through the elastic rope 302i, releasing the restriction effect on the deformable part 201. At this time, the length of the deformable part 201 inside the frame 301a can be freely adjusted. When the appropriate position is reached, the operating plate 302e can be released. Under the action of the spring 302d, the operating plate 302e moves downward and forces the squeezing valve 302h to close, forming a clamp and limit on the deformable part 201.
