Description

Technical Field

[0001] This application relates to the field of polishing machine technology, and in particular to a lighting system for a polishing machine. Background Technology

[0002] Wall sanders are key tools in the construction and decoration industry, mainly used for fine sanding of walls to ensure a smooth and clean surface, laying the foundation for subsequent painting operations.

[0003] To adapt to different usage needs, some wall sanders are equipped with two replaceable sanding discs: a circular sanding disc and a triangular sanding disc. Because the circular sanding disc has a sufficient area, its lighting system is usually integrated into the connection part connected to the body. However, the triangular sanding disc, because it needs to vibrate, is often equipped with other components, such as an eccentric block and a swing angle. This makes the internal structure of the triangular sanding disc too compact, making it difficult to incorporate a lighting structure. Furthermore, because the triangular sanding disc needs to swing to adapt to different corners, it is prone to interference. Therefore, how to solve the above problems is the purpose of this application.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0005] Based on this, this application provides a lighting system for a grinder to solve one of the aforementioned technical problems.

[0006] The technical solution adopted by this application to solve its technical problem is a lighting system for a grinding machine, including: a machine body shell and a grinding disc, the grinding disc being divided into a circular grinding disc and a triangular grinding disc, the grinding disc including a top shell, a base, and a grinding part, the base being installed between the top shell and the grinding part, the top of the top shell being provided with a connecting part for connecting to the machine body shell, the base being provided with a socket for connecting a power cord, the socket of the triangular grinding disc being located at any corner, and a light strip conforming to the contour of the grinding disc being provided on the outer periphery of the grinding disc and electrically connected to the socket.

[0007] In some embodiments, the edge of the base is provided with a cable groove for placing cables to connect the light strip.

[0008] In some embodiments, a line-blocking portion is provided above the base of the circular grinding disc to restrict the direction of the line.

[0009] In some embodiments, the top shell has a dust-blocking block formed above the cable channel that matches the contour of the cable channel.

[0010] In some embodiments, the cable groove width of the triangular grinding disc is smaller than the cable groove width of the circular grinding disc.

[0011] In some embodiments, an adapter groove is additionally provided below the insertion hole of the triangular grinding disc, and the adapter groove is connected to the cable groove.

[0012] The beneficial effect of this application is that by setting the socket of the light strip at any corner of the triangular grinding disc, the socket can be directly connected to the cable groove without being interfered with by the connecting part of the triangular grinding disc and is separated from the internal structure of the triangular grinding disc, thus ensuring the stability of the triangular grinding disc during use.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0020] In the embodiments of this application, please refer to Figure 1-4As shown, this application provides a lighting system for a grinder, mainly including: a machine body shell 1 and a grinding disc 2. The grinding disc 2 is divided into a circular grinding disc 2 and a triangular grinding disc 2. The grinding disc 2 includes a top shell 21, a base 22, and a grinding part 23. The base 22 is installed between the top shell 21 and the grinding part 23. The top of the top shell 21 is provided with a connecting part 24 for connecting to the machine body shell 1. The base 22 is provided with a socket 25 for connecting a power cord. The socket 25 of the triangular grinding disc 2 is located at any corner. A light strip 26 conforming to the contour of the grinding disc 2 is provided on the outer periphery of the grinding disc 2 and is electrically connected to the socket 25.

[0021] Specifically, the triangular grinding disc 2 separates the light strip 26 from the internal structure, and the two do not interfere with each other, thus ensuring the cleanliness of the internal structure of the triangular grinding disc 2.

[0022] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0023] Reference Figure 3 As shown, in order to prevent the cable connecting the socket 25 and the light strip 26 from interfering with the internal structure of the grinding disc 2, the edge of the base 22 is provided with a cable groove 221 for placing the cable to connect the light strip 26.

[0024] Preferably, a wire-blocking part 223 is provided above the base 22 of the circular grinding disc 2 to restrict the direction of the wire. The wire-blocking part 223 can serve as a transfer position for connecting cables to the socket 25. The wide range of the wire-blocking part 223 makes it convenient for the cable to be laid.

[0025] Reference Figure 4 As shown, the top shell 21 has a dust-blocking block 211 formed above the cable groove 221 that matches the contour of the cable groove 221. With this configuration, the dust-blocking block 211 can block the position above the cable groove 221 when the top shell 21 is installed above the base 22, preventing dust from entering the inside of the cable groove 221.

[0026] Reference Figure 3 As shown, an additional adapter groove 222 is provided below the insertion hole 25 of the triangular grinding disc 2. The adapter groove 222 is connected to the cable groove 221. The function of the adapter groove 222 is the same as that of the cable blocking part 223, which can make the cable connection more reasonable over a wider range and facilitate the cable laying.

[0027] Specifically, the connecting part 24 of the triangular grinding disc 2 is swingable, and the swing range of the connecting part 24 will not interfere with the socket 25. This setting ensures that the triangular grinding disc 2 will not interfere with the swingable connecting part 24 when the socket 25 is connected.

[0028] The various embodiments of this application have now been described in detail. To avoid obscuring the concept of this application, some details known in the art have not been described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of this application. The foregoing embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. These modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
