Description

Technical Field

[0001] This utility model relates to the field of power tool technology, and in particular to a light-guiding bending indicator light structure for power tools. Background Technology

[0002] Currently, indicator lights on power tools typically use a direct-lighting structure, where the LED light shines directly into the light-transmitting window of the casing. However, due to the compact internal structure of power tools, the direct-lighting structure requires a large straight light transmission path, which limits the installation location and makes it difficult to adapt to complex layouts. Furthermore, direct-lighting can easily cause excessively high local brightness or uneven light distribution, affecting the user's observation experience, especially in bright light environments where visibility is poor.

[0003] To address this issue, this utility model proposes a light-guiding bending indicator light structure for power tools. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a light-guiding bending indicator structure for power tools, so as to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, one embodiment of this utility model provides a light-guiding bending indicator light structure for an electric tool, including a housing, the housing comprising a first outer shell and a second outer shell; further comprising: a circuit board, serving as a processing element of the electric tool, disposed between the first and second outer shells, on which an indicator light is fixedly mounted; a lampshade, having an L-shaped bending structure, having a hollow cavity inside, with one end being an open end and the other end being a closed end, the open end of the lampshade being tightly fitted onto the indicator light; and a light-refracting plate, fixedly mounted within the hollow cavity, used to refract light entering the lampshade to the closed end, and to transmit light outward from the closed end for display.

[0007] Preferably, in any of the above solutions, the first outer shell and the second outer shell are detachably connected by countersunk bolts.

[0008] Preferably, in any of the above solutions, a first support block, a second support block, and a third support block are fixedly provided inside the first housing, the first support block has a first groove, and the second support block and the third support block are spaced apart to form a second groove.

[0009] Preferably, one end of the circuit board is engaged in the first groove, and the other end of the circuit board is engaged in the second groove.

[0010] Preferably, in any of the above solutions, a pressure plate and a limiting plate are fixedly provided inside the second housing, and the pressure plate is used to press the circuit board into the first groove.

[0011] Preferably, in any of the above solutions, a through groove is provided on the first outer shell, and the lampshade is fixedly installed in the through groove.

[0012] Preferably, any of the above embodiments further includes: a push switch, wherein the push switch is disposed between the first housing and the second housing, and is rotatably connected by a rotating shaft, wherein the first end of the rotating shaft is rotatably connected to the first housing and the second end is rotatably connected to the second housing, and a limiting plate is fixedly provided at the tail end of the push switch; and a reset spring, one end of which is fixedly mounted on the push switch and the other end is fixedly connected to a protruding plate inside the first housing, for providing a reset force to the push switch.

[0013] Preferably, in any of the above embodiments, the lampshade is made of an opaque material, and the closed end is made of a translucent material; the bend of the lampshade is an arc surface, and the light-refracting plate is installed at the arc surface.

[0014] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0015] 1. The lampshade adopts an L-shaped bending design, which, together with the light-refracting plate, allows the light path of the indicator light to be conducted along the bending direction. This avoids the dependence of the traditional direct-light structure on straight space, and is especially suitable for power tools with compact internal structures. The light-transmitting design of the closed end of the lampshade, combined with the refraction of the light-refracting plate, realizes the light-transmitting bending, allowing the light-emitting parts to be flexibly arranged in non-linear positions, improving the layout freedom.

[0016] 2. By refracting light through a light-refraction plate, light is precisely guided from the open end to the closed end, avoiding light scattering loss and improving light energy utilization. The overall design of the lampshade is opaque, with light only passing through the closed end, ensuring that light is concentrated and passes through the designated area, resulting in clearer display, avoiding stray light interference, and enhancing visibility in strong light environments.

[0029] like Figures 1 to 9 As shown, a light-guiding bending indicator structure for an electric tool includes a housing 1, a circuit board 2, a lampshade 3, and a light-reflecting plate 4.

[0030] Furthermore, the housing 1 includes a first outer shell 11 and a second outer shell 12;

[0031] The first outer shell 11 and the second outer shell 12 are detachably connected by countersunk bolts;

[0032] The first outer shell 11 is fixedly provided with a first support block 1101, a second support block 1102 and a third support block 1103. The first support block 1101 is provided with a first groove 1104. The second support block 1102 and the third support block 1103 are spaced apart to form a second groove 1105.

[0033] The second outer casing 12 is fixedly provided with a pressure plate 1201 and a limiting plate 1202. The pressure plate 1201 is used to press the circuit board 2 into the first groove 1104.

[0034] The first outer shell 11 has a through groove, and the lampshade 3 is fixedly installed in the through groove.

[0035] Furthermore, the circuit board 2, as a processing element of this power tool, is disposed between the first housing 11 and the second housing 12, and an indicator light 21 is fixedly mounted on the circuit board 2;

[0036] One end of the circuit board 2 is engaged in the first groove 1104, and the other end of the circuit board 2 is engaged in the second groove 1105.

[0037] The two ends of the circuit board 2 are respectively inserted into the first groove 1104 and the second groove 1105, and the circuit board 2 is pressed by the pressure plate 1201. The limiting plate 1202 is used to provide a resisting force to the circuit board 2 to disperse the force on the circuit board 2.

[0038] Furthermore, the lampshade 3 has an L-shaped bent structure with a hollow cavity inside, and one end is an open end 31 and the other end is a closed end 32. The open end 31 of the lampshade 3 is tightly fitted onto the indicator light 21.

[0039] The lampshade 3 is made of opaque material, while the closed end 32 is made of light-transmitting material.

[0040] When the indicator light 21 on the circuit board 2 is lit, since the lamp cover 3 is made of opaque material, the light of the indicator light 21 will not diffuse outward from the lamp cover 3. Therefore, the light will shine on the light refraction plate 4, be refracted through the light refraction plate 4 to the closed end 32 of the lamp cover 3, and then shine outward from the closed end 32.

[0041] The lampshade 3 has an arc-shaped bend, and the light-refractive plate 4 is installed on this arc-shaped surface;

[0042] The inclined surface and the arc-shaped light-refracting plate 4 ensure the stability of light refraction.

[0043] Furthermore, the light-refracting plate 4 is fixedly installed in the hollow cavity to refract the light entering the lampshade 3 to the closed end 32, and then transmit it outward from the closed end 32 for display.

[0044] The refracting plate 4 can be used as a light refraction element.

[0045] Furthermore, it also includes:

[0046] The push switch 5 is located between the first housing 11 and the second housing 12 and is rotatably connected by a rotating shaft 51. The first end of the rotating shaft 51 is rotatably connected to the first housing and the second end is rotatably connected to the second housing. A limiting plate 52 is fixedly provided at the tail end of the push switch 5. The limiting plate 52 limits the movement of the push switch 5 and prevents the push switch 5 from detaching from the housing 1.

[0047] The reset spring 6 has one end fixedly mounted on the push switch 5 and the other end fixedly connected to the protruding plate inside the first housing 11. It is used to provide a reset force for the push switch 5. When a pressing force is applied to the push switch 5, the reset spring 6 is compressed. After the push switch 5 is released, the push switch 5 is driven to reset under the action of the reset spring 6.
