Description

Technical Field

[0001] This utility model relates to the field of incoming and outgoing line protection technology, specifically a protective sleeve for the incoming and outgoing lines of an electricity meter. Background Technology

[0002] In power systems, the outgoing lines of electricity meters are crucial. Traditional electricity meter outgoing lines are often exposed or wrapped with simple insulating materials, lacking effective independent protection. This leads to frequent phase-to-phase short circuits and grounding faults in complex electrical environments, especially under conditions of multiple parallel lines, frequent operation, and environmental factors. For example, during the renovation of power systems in old residential areas, when workers replace a large number of electricity meters, exposed wires during installation can cause phase-to-phase short circuits or grounding faults due to friction between the wires and the meter box casing, resulting in local power outages and damage to electrical equipment. This seriously affects the safety of residents' electricity use and the stability of power supply. Based on this, a protective sleeve for the incoming and outgoing lines of electricity meters is provided. Utility Model Content

[0003] The purpose of this utility model is to provide a protective sleeve for the incoming and outgoing lines of an electricity meter in order to solve the problems mentioned above.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a protective sleeve for the inlet and outlet lines of an electricity meter, comprising a protective sleeve, wherein the protective sleeve is composed of a C-shaped rubber sleeve, an inner arc-shaped butt joint piece, an outer arc-shaped butt joint piece, an interlocking rubber piece, and a concave groove;

[0005] The inner arc-shaped butt joint piece and the outer arc-shaped butt joint piece are respectively fixed to both ends of the C-shaped rubber sleeve. The interlocking rubber pieces are respectively fixed to the outer side of the inner arc-shaped butt joint piece and the inner side of the outer arc-shaped butt joint piece. The C-shaped rubber sleeve is sleeved on the outer side of the inlet and outlet lines and the inner arc-shaped butt joint piece and the outer arc-shaped butt joint piece are brought close to each other and connected. The C-shaped rubber sleeve wraps and fixes the inlet and outlet lines by the interlocking of the two sets of interlocking rubber pieces.

[0006] The concave groove is formed on the outside of the C-shaped rubber sleeve and completely penetrates the inner arc-shaped butt joint and the outer arc-shaped butt joint. The C-shaped rubber sleeve is connected to an elastic fastener through the concave groove. The elastic fastener is used to provide locking and limiting for the wrapping state of the C-shaped rubber sleeve.

[0007] As a further embodiment of this utility model: the elastic fastener includes a C-shaped spring buckle, an inner arc-shaped locking block, an outer arc-shaped locking block, and a ratchet;

[0008] The inner arc-shaped locking block and the outer arc-shaped locking block are respectively fixed to both ends of the C-shaped spring buckle. The inner side of the C-shaped spring buckle and the inner arc-shaped locking block is fixed to the inner side of the concave groove. The upper and lower edges of the C-shaped spring buckle, the inner arc-shaped locking block and the outer arc-shaped locking block are fixed to the upper and lower end faces of the inner wall of the concave groove. The ratchet is respectively fixed to the outer side of the inner arc-shaped locking block and the inner side of the outer arc-shaped locking block.

[0009] The C-type snap fastener initially has a "C"-shaped structure, which is used to provide support for the C-type rubber sleeve when it is open.

[0010] The C-shaped snap-lock opening closes to engage the two sets of ratchet teeth on the inner and outer arc-shaped locking blocks, thereby locking the C-shaped rubber sleeve in place.

[0011] As a further improvement of this utility model: the outer side of the C-shaped snap fastener and the outer arc-shaped locking block is formed with an arc-shaped locking groove.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 In this embodiment of the utility model, a protective sleeve for the incoming and outgoing lines of an electricity meter includes a protective sleeve 1, which is composed of a C-shaped rubber sleeve 101, an inner arc-shaped butt joint piece 102, an outer arc-shaped butt joint 103, an interlocking rubber piece 104, and a concave groove 105.

[0023] The inner arc-shaped butt joint 102 and the outer arc-shaped butt joint 103 are respectively fixed to both ends of the C-shaped rubber sleeve 101. The interlocking rubber sheets 104 are respectively fixed to the outer side of the inner arc-shaped butt joint 102 and the inner side of the outer arc-shaped butt joint 103. The C-shaped rubber sleeve 101 is sleeved on the outer side of the inlet and outlet lines and the inner arc-shaped butt joint 102 and the outer arc-shaped butt joint 103 are brought close to each other and connected. The C-shaped rubber sleeve 101 wraps and fixes the inlet and outlet lines by the interlocking of the two sets of interlocking rubber sheets 104.

[0024] The concave groove 105 is formed on the outside of the C-shaped rubber sleeve 101 and completely penetrates the inner arc-shaped butt piece 102 and the outer arc-shaped butt piece 103. The C-shaped rubber sleeve 101 is connected to the elastic fastener 2 through the concave groove 105. The elastic fastener 2 is used to provide locking and limiting for the wrapping state of the C-shaped rubber sleeve 101.

[0025] The elastic fastener 2 includes a C-shaped spring buckle 201, an inner arc-shaped locking block 202, an outer arc-shaped locking block 203, and a ratchet 204;

[0026] The inner arc-shaped locking block 202 and the outer arc-shaped locking block 203 are respectively fixed to both ends of the C-shaped spring buckle 201. The inner sides of the C-shaped spring buckle 201 and the inner arc-shaped locking block 202 are fixed to the inner side of the concave groove 105. The upper and lower edges of the C-shaped spring buckle 201, the inner arc-shaped locking block 202 and the outer arc-shaped locking block 203 are fixed to the upper and lower end faces of the inner wall of the concave groove 105. The ratchet 204 is respectively fixed to the outer side of the inner arc-shaped locking block 202 and the inner side of the outer arc-shaped locking block 203.

[0027] The C-type snap fastener 201 initially has a "C"-shaped structure, which is used to provide support for the open state of the C-type rubber sleeve 101;

[0028] The opening of the C-type snap fastener 201 closes so that the two sets of ratchet teeth 204 on the inner arc-shaped locking block 202 and the outer arc-shaped locking block 203 engage with each other to achieve locking of the C-type rubber sleeve 101 in the wrapped state.

[0029] The outer side of the C-type spring clip 201 and the outer arc-shaped locking block 203 is formed with an arc-shaped locking groove 205. The C-type spring clip 201 is engaged with the inner side of the cable outlet hole of the meter box shell through the arc-shaped locking groove 205 to achieve relative fixation between the protective sleeve 1 and the meter box shell.

[0030] In this embodiment, when using this protective sleeve 1 to protect the incoming and outgoing lines of the electricity meter, the operating steps are as follows:

[0031] First, position the incoming and outgoing lines of the electricity meter in a "C" shape from their initial state with the C-shaped sleeve 101 and C-shaped spring clip 201. In this way, the incoming and outgoing lines can be connected to the outside of the incoming and outgoing lines through the opening of the C-shaped sleeve 101 and C-shaped spring clip 201. During this process, the C-shaped sleeve 101 and C-shaped spring clip 201 can be slightly pried open to make the opening of the C-shaped sleeve 101 and C-shaped spring clip 201 large enough for the incoming and outgoing lines to pass through.

[0032] Then, while keeping the C-shaped rubber sleeve 101 and the C-shaped spring buckle 201 open, move the entire protective sleeve 1 downwards along the inlet and outlet lines, closer to the inlet and outlet lines of the meter box casing. Then, slightly tilt the bottom C-shaped spring buckle 201, so that one end of the C-shaped spring buckle 201 near the inner arc-shaped locking block 202 is engaged with the inner side of the inlet and outlet lines through the arc-shaped locking groove 205. Next, press the other end of the C-shaped spring buckle 201, causing it to retract and move downwards, fully engaging with the inner side of the inlet and outlet lines. During this process, the outer arc-shaped locking block 203 and the inner arc-shaped locking block 202 move closer to each other. The two sets of ratchet teeth 204 on the inner arc-shaped locking block 202 and the outer arc-shaped locking block 203 are squeezed and deformed against each other. When the two sets of ratchet teeth 204 are staggered, they will reset and lock against each other under their own elastic force. Finally, the C-type spring buckle 201, the inner arc-shaped locking block 202 and the outer arc-shaped locking block 203 form a ring structure and are fixed to the inlet and outlet of the inlet and outlet of the line. This not only seals the inlet and outlet of the line, but also fixes the protective sleeve 1 to the outer shell of the meter box. In addition, the C-type spring buckle 201 has good hardness and can overcome the friction with the outer shell of the meter box, avoiding the inlet and outlet of the line from contacting and rubbing against the outer shell of the meter box and causing damage.

[0033] Then, multiple elastic fasteners 2 are closed sequentially from bottom to top. During this process, the C-shaped rubber sleeve 101 is driven to close synchronously. Its inner arc-shaped butt joint piece 102 and outer arc-shaped butt joint piece 103 overlap each other, and the two sets of interlocking rubber pieces 104 on the inner arc-shaped butt joint piece 102 and outer arc-shaped butt joint piece 103 are interlocked with each other, thus achieving the wrapping and protection of the incoming and outgoing lines.

[0034] It should be further explained that when the C-type rubber sleeve 101, the inner arc-shaped connecting piece 102, and the outer arc-shaped connecting piece 103 are in a ring shape, the inner ring diameter of the C-type rubber sleeve 101 matches the outer diameter of the incoming and outgoing lines. Through the friction between the C-type rubber sleeve 101 and the incoming and outgoing lines, the part of the incoming and outgoing lines located in the meter box housing can also be prevented from being pulled by the outside, thereby making the connection between the incoming and outgoing lines and the electricity meter more stable.

[0035] Please refer to this carefully. Figures 1-3 The outer sides of the C-shaped snap 201 and the outer arc-shaped locking block 203 are also provided with several anti-slip textures 206 that are evenly distributed along the trajectory of the C-shaped snap 201 and the outer arc-shaped locking block 203.

[0036] In this embodiment: the anti-slip texture 206 structure makes it easy to apply pressure to the C-type snap 201 to achieve the closing operation.

[0037] Please refer to this carefully. Figures 1-3 Multiple concave grooves 105 are evenly arranged along the long side of the C-shaped rubber sleeve 101, and the number of elastic fasteners 2 matches the number of concave grooves 105.

[0038] In this embodiment: the structure of multiple sets of elastic fasteners 2 can provide sufficient locking force for the closed state of the C-type rubber sleeve 101, so as to achieve good protection for the incoming and outgoing lines;

[0039] In addition, the C-shaped rubber sleeve 101, located in the middle of two adjacent elastic fasteners 2, can be bent according to the direction of the inlet and outlet lines to adapt to the distribution of the inlet and outlet lines, and the C-shaped rubber sleeve 101 can be freely cut to the required length, making it more flexible to use.

[0040] Please refer to this carefully. Figures 1-3 The C-shaped rubber sleeve 101, the inner arc-shaped mating piece 102, the outer arc-shaped mating piece 103, the interlocking rubber piece 104, and the concave groove 105 are integrally formed by rubber injection molding. The C-shaped spring buckle 201, the inner arc-shaped locking block 202, the outer arc-shaped locking block 203, the ratchet 204, the arc-shaped locking groove 205, and the anti-slip texture 206 are integrally formed by plastic injection molding.

[0041] In this embodiment: After the protective sleeve 1 and the elastic fastener 2 are independently molded by injection molding, the elastic fastener 2 can be glued and fixed to the protective sleeve 1. The overall production and assembly process is simple and easy to promote and produce.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
