Description

Technical Field

[0001] This utility model relates to the field of electricity meter technology, and more specifically to a light guide structure for an indicator light and an electricity meter. Background Technology

[0002] Electricity meters typically have light guides longer than 30mm installed on their indicator lights. In related technologies, such as... Figure 1 As shown, the light guide post 130' is usually manufactured separately and then separately installed on the cover 140' with the viewing window 150'. However, such a structure has high manufacturing costs and affects the waterproof performance of the modified product. Figure 2 As shown, the integral molding of the light guide post 130' and the lens 160' can cause air bubbles inside the light guide post, affecting the light guiding performance. Utility Model Content

[0003] The present invention aims to at least solve or improve the technical problem of the complex installation process of the light guide column of the electricity meter in the related art.

[0004] Therefore, the first aspect of this utility model proposes a light guide structure for an indicator light.

[0005] A second aspect of this utility model provides an electricity meter.

[0006] In view of the above, according to the first aspect of the present invention, the present invention provides a light guide structure for an indicator light, comprising: a light-transmitting base, the light-transmitting base including a first plate and at least two mounting sleeves, the mounting sleeves protruding from one side of the first plate and having a blind hole at one end of the mounting sleeve facing away from the first plate; a light guide post, the light guide post including at least two pillars and at least one connecting portion, the at least one connecting portion connecting at least two pillars, the pillars and the mounting sleeves corresponding one-to-one; wherein the pillars and the mounting sleeves are connected by an interference fit.

[0007] The light guide structure of the indicator light proposed in this utility model includes a light-transmitting base and a light guide column. The light guide column is set on the light-transmitting base, thereby forming a whole to guide the light emitted by the indicator light.

[0008] The light-transmitting base includes a first plate and at least two mounting sleeves disposed on the first plate. Each mounting sleeve protrudes from one side of the first plate and has blind holes with openings on the side of the mounting sleeve facing away from the first plate. The light guide post includes at least two pillars and at least one connecting portion for connecting the at least two pillars. The connecting portion connects the at least two pillars into a single unit, facilitating the installation of the light guide post. During installation, the pillars and blind holes correspond one-to-one, and the pillars are then inserted into the blind holes to complete the installation of the light-transmitting base and the light guide post. Since the light guide post includes at least two pillars, at least two pillars can be installed at once, reducing the installation steps and difficulty. Furthermore, the light guide post and the light-transmitting base are separate structures, reducing the possibility of air bubbles between them and ensuring the light guiding effect of the indicator light's light guiding structure. The blind holes on the mounting sleeves improve the waterproof and dustproof performance of the indicator light's light guiding structure.

[0009] Furthermore, the column and the mounting sleeve are connected by an interference fit, which is highly reliable, simple to install, and low in cost.

[0010] In some technical solutions, optionally, one end of the connecting part is connected to a column, and the other end of the connecting part is connected to another column; or the connecting part surrounds the periphery of at least two columns.

[0011] In this technical solution, one end of the connecting part is connected to a column, and the other end of the connecting part is connected to another column. That is, a column, a connecting part, and a column are arranged in sequence. Of course, this arrangement is not limited to a straight line arrangement, but can also be any shape such as an arc. This structure is conducive to saving materials and reducing costs.

[0012] Alternatively, the connector may surround the periphery of at least two pillars, thereby increasing the connection strength between the connector and the pillars, reducing the possibility of breakage between the connector and the pillars, and improving the reliability of the light guide pillar.

[0013] In some technical solutions, optionally, the column and the connecting part are an integral structure; the first plate and the mounting sleeve are an integral structure.

[0014] In this technical solution, the column and the connecting part are integrated into one structure, thereby improving the connection strength between the column and the connecting part and reducing the installation steps of the light guide column.

[0015] The first plate and the mounting sleeve are integrated into one structure, thereby improving the connection strength between the first plate and the mounting sleeve and reducing the installation steps of the light-transmitting base.

[0016] In some technical solutions, optionally, at least two columns are arranged in a single row.

[0017] In this technical solution, at least two pillars are arranged in a single row, which reduces the production difficulty of the light guide pillars. When performing processes such as injection molding, the arrangement of at least two pillars in a single row makes it easier to set up molds and demold, thereby reducing the production cost of the light guide pillars.

[0018] In some technical solutions, optionally, the mounting sleeve is chamfered at the edge of the blind hole.

[0019] In this technical solution, the mounting sleeve forms a chamfer at the edge of the blind hole, which facilitates the insertion of the column and reduces the installation difficulty between the light guide column and the light-transmitting base.

[0020] In some technical solutions, optionally, the column is a cylindrical structure; the mounting sleeve is a circular structure; and the blind hole is a circular hole structure.

[0021] In this technical solution, the column is a cylindrical structure, which allows for better control of the column's surface and reduces the impact of corner issues on the yield of the light guide column. The mounting sleeve is a circular ring structure, which allows for better control of the inner surface and reduces the impact of corner issues on the yield of the light-transmitting base. The blind hole is a circular hole structure to better fit the light guide column.

[0022] In some technical solutions, optionally, the solution also includes: a cover, a light-transmitting base fixed on the cover, the cover having a through hole, the through hole and the light guide post being arranged opposite to each other, and the cover and the light-transmitting base being fixedly connected by ultrasonic welding.

[0023] In this technical solution, the light guide column of the indicator light also includes a cover, and a light-transmitting base is fixed on the cover. The light guide column is located on the side of the light-transmitting base away from the cover. The cover has a through hole, and the through hole and the light guide column are arranged opposite to each other, that is, the ground of the through hole and the blind hole are opposite to each other. Light can be transmitted to the outside of the cover through the light guide column, the light-transmitting base and the through hole. The cover and the light-transmitting base are fixedly connected by ultrasonic welding, thereby ensuring the connection strength between the cover and the light-transmitting base and improving the reliability between the cover and the light-transmitting technology.

[0024] In some technical solutions, the through hole and the light guide post can optionally be arranged coaxially.

[0025] In this technical solution, the through hole and the light guide post are set coaxially to ensure the light guiding effect of the indicator light's light guide structure.

[0026] In some technical solutions, the cover may optionally have a viewing window, and the light-transmitting base may also include a second plate that covers the viewing window.

[0027] In this technical solution, the cover has a viewing window to provide an observation port for the electricity meter. The light-transmitting base also includes a second plate that covers the viewing window to protect the electricity meter. Furthermore, the entire light-transmitting base can be an integral structure, thereby reducing the installation difficulty of the light-transmitting base.

[0028] According to a second aspect of the present invention, an energy meter is provided, comprising: a main body, on which an indicator light is provided; and a light guide structure for the indicator light as provided in the first aspect of the present invention, wherein the light guide structure for the indicator light is fixed on the main body, and the light guide column of the light guide structure for the indicator light is opposite to the indicator light.

[0048] 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. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0049] The following reference Figures 1 to 11 This invention describes a light guide structure 100 for an indicator light and an energy meter 200 provided according to some embodiments of the present invention.

[0050] like Figures 3 to 6As shown, according to a first aspect embodiment of the present invention, the present invention provides a light guide structure 100 for an indicator light. The light guide structure 100 for an indicator light is used in an electricity meter 200. The light guide structure 100 includes a light-transmitting base 110 and a light guide post 130. The light guide post 130 is mounted on the light-transmitting base 110. The light-transmitting base 110 includes a first plate 112 and at least two mounting sleeves 114. The first plate 112 and the at least two mounting sleeves 114 can be integrally formed or have a separate structure. The mounting sleeve 114 protrudes from one side of the first plate 112. A blind hole 116 is provided at one end of the mounting sleeve 114 away from the first plate 112. The light guide post 130 is inserted into the blind hole 116.

[0051] The light guide post 130 includes at least two posts 132 and at least one connecting part 134. The at least two posts 132 and at least one connecting part 134 can be integrally formed or have a split structure.

[0053] The light guide structure 100 of the indicator light provided by this utility model includes a light-transmitting base 110 and a light guide column 130. The light guide column 130 is disposed on the light-transmitting base 110, thereby forming an integral whole to guide the light emitted by the indicator light 212.

[0054] The light-transmitting base 110 includes a first plate 112 and at least two mounting sleeves 114 disposed on the first plate 112. Each mounting sleeve 114 protrudes from one side of the first plate 112 and has a blind hole 116.

They are assembled together by interference fit, thereby solving the protection performance of the light guide column 130 of the light guide structure 100 of the indicator light and improving the assembly efficiency.

[0057] Multiple pillars 132 can be combined into a light guide pillar 130, which facilitates production and molding, and also facilitates the assembly of the light guide pillar 130 with the light-transmitting base 110. The light guide pillar 130 can be combined in various ways according to requirements. The length of the pillar 132, the number of pillars 132, and the connection method of the pillars 132 can all be different according to different requirements.

[0058] The light-transmitting base 110 can be made of glass, plastic, or polymer materials, and the light guide column 130 can be made of glass, plastic, or polymer materials.

The connecting portion 134 can be a straight plate structure or a curved plate structure, etc.

[0060] In this embodiment, one end of the connecting part 134 is connected to a column 132, and the other end of the connecting part 134 is connected to another column 132. That is, a column 132, a connecting part 134, and a column 132 are arranged in sequence. Of course, the arrangement is not limited to a straight line arrangement, but can also be any shape such as an arc. This structure is beneficial to save materials and reduce costs.

[0061] like Figure 10 As shown, in some embodiments, optionally, the connecting portion 134 surrounds the periphery of at least two pillars 132. That is, the pillars 132 are embedded in the connecting portion 134, and the connecting portion 134 is connected to a portion of the periphery wall of the pillars 132.

[0062] In this embodiment, the connecting portion 134 surrounds the periphery of at least two pillars 132, thereby increasing the connection strength between the connecting portion 134 and the pillars 132, reducing the possibility of breakage between the connecting portion 134 and the pillars 132, and improving the reliability of the light guide pillar 130.

[0063] like Figure 9 and Figure 10 As shown, in some embodiments, the column 132 and the connecting part 134 are optionally integrated.

[0064] In this embodiment, the column 132 and the connecting part 134 are an integral structure, thereby improving the connection strength between the column 132 and the connecting part 134 and reducing the installation steps of the light guide column 130.

[0065] like Figure 5 and Figure 6 As shown, in some embodiments, the first plate 112 and the mounting sleeve 114 are optionally integrated.

[0066] The first plate 112 and the mounting sleeve 114 are integrated into one structure, thereby improving the connection strength between the first plate 112 and the mounting sleeve 114 and reducing the installation steps of the light-transmitting base 110.

[0067] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 9 As shown, in some embodiments, optionally, at least two columns 132 are arranged in a single row.

[0068] In this embodiment, at least two pillars 132 are arranged in a single row, thereby reducing the production difficulty of the light guide pillar 130. When performing processes such as injection molding, the single-row arrangement of at least two pillars 132 makes it easier to set up molds and demold, thus reducing the production cost of the light guide pillar 130.

[0069] Specifically, one, two or more light guide columns 130 can be installed on a light-transmitting base 110 to form a structure that meets the requirements.

[0070] like Figure 7 and Figure 8 As shown, in some embodiments, the mounting sleeve 114 optionally forms a chamfer 118 at the edge of the blind hole 116.

[0071] In this embodiment, the mounting sleeve 114 forms a chamfer 118 at the edge of the blind hole 116, which facilitates the insertion of the column 132 and reduces the installation difficulty between the light guide column 130 and the light-transmitting base 110.

[0072] That is, the mounting sleeve 114 on the light-transmitting base 110 and the column 132 on the light guide column 130 are tightly and firmly fixed to the light-transmitting base 110 by interference fit. The mounting sleeve 114 has a chamfer 118 at the opening to facilitate the assembly and positioning of the light guide column 130.

[0074] In this embodiment, the column 132 is a cylindrical structure, which can better control the surface of the column 132 and reduce the impact of corner problems on the yield of the light guide column 130. The mounting sleeve 114 is a ring structure, which can better control the inner surface and reduce the impact of corner problems on the yield of the light-transmitting base 110. The blind hole 116 is a circular hole structure to better fit the light guide column 130.

[0075] like Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, in some embodiments, optionally, the light guide structure 100 of the indicator light also includes a cover 140, a light-transmitting base 110 fixed on the cover 140, the light-transmitting base 110 and the cover 140 are connected by ultrasonic welding, and the cover 140 is provided with a through hole 142, the through hole 142 and the light guide post 130 are arranged opposite to each other on both sides of the light-transmitting base 110.

[0076] In this embodiment, the light guide post 130 of the indicator light 212 also includes a cover 140, and a light-transmitting base 110 is fixed on the cover 140. The light guide post 130 is located on the side of the light-transmitting base 110 away from the cover 140. The cover 140 has a through hole 142, which is opposite to the light guide post 130, that is, the through hole 142 and the ground of the blind hole 116 are opposite. Light can be transmitted to the outside of the cover 140 through the light guide post 130, the light-transmitting base 110 and the through hole 142. The cover 140 and the light-transmitting base 110 are fixedly connected by ultrasonic welding, thereby ensuring the connection strength between the cover 140 and the light-transmitting base 110 and improving the reliability between the cover 140 and the light-transmitting technology.

[0077] In other words, by using ultrasonic welding technology, the light-transmitting base 110 is welded to the cover 140 to improve the overall protection performance of the electricity meter 200. The light guide structure 100 of the indicator light provided by this utility model can solve the waterproof problem of the electricity meter 200. The light-transmitting base 110 is designed as an integrally formed light-transmitting component, and the light-transmitting base 110 and the cover 140 are ultrasonically welded to ensure that the through hole 142 on the cover 140 will not allow liquid to enter, thereby improving the reliability of the electricity meter 200. The light guide column 130 is grouped and installed into the mounting sleeve 114 of the light-transmitting base 110 by interference fit.

[0078] like Figure 5 and Figure 6 As shown, in some embodiments, the through hole 142 and the light guide post 130 are optionally arranged coaxially.
