DETAILED DESCRIPTION

[0041] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Work lights are suitable for lighting various large and medium-sized CNC machine tools, modular machine tools, machining centers, ordinary machine tools, and indoor lighting of closed CNC machine tools. They need to be sealed and waterproof to ensure their normal operation. In addition, since work lights generate a lot of heat when working, poor heat dissipation will seriously affect the normal operation of work lights. In the prior art, the waterproof and heat dissipation performance of work lights are not ideal.

[0043] Therefore, the present invention designs a work light with good waterproof and heat dissipation performance. Figure 1 is an exploded view of a work light provided by an embodiment of the present invention, such as Figure 1 As shown, the work lamp includes: soft plastic 1, inner shell 2, base 3 and outer shell 4; the soft plastic 1 covers the top end of the inner shell 2; the base 3 wraps the bottom end of the inner shell 2 and is fixed to the inner shell 2 by screws; the outer shell 4 surrounds and fixes the part of the soft plastic 1, the inner shell 2 and the base 3, the top end of the outer shell 4 abuts against the soft plastic 1, the bottom end of the outer shell 4 abuts against the base 3, and the inner surface of the outer shell 4 and the outer surface of the base 3 are connected by a first sealing ring 5; wherein, the inner shell 2 is made of plastic, the outer shell 4 is made of metal, and the base 3 is made of hard plastic.

[0044] like Figure 1 As shown, the soft plastic 1 covers the top of the inner shell 2, and the two are not shown separately, and waterproofing is achieved between the two. The outer shell 4 surrounds the part that fixes the soft plastic 1, the inner shell 2 and the base 3.

[0045] The base 3 includes two parts: a first connecting member and a second connecting member, wherein the height of the first connecting member is lower than that of the second connecting member, and the first connecting member and the second connecting member wrap the bottom end of the inner shell 2 in sequence; wherein the outer shell 4 surrounds and fixes the first connecting member; and a through hole is provided on the second connecting member for fixing to the inner shell 2 by screws.

[0046] The inner surface of the housing 4 and the outer surface of the base 3 are butted against each other by a first sealing ring 5 to achieve waterproofing. Furthermore, the material selection of the first sealing ring 5 directly affects the sealing and waterproofing performance of the work light. The first sealing ring 5 can be made of EPDM terpolymer rubber sealing ring, which has good weather resistance, ozone resistance, water resistance and chemical resistance. In the present invention, the material of the first sealing ring 5 is not limited, as long as the waterproofing and sealing performance of the first sealing ring 5 meet the standards.

[0047] In addition, in the present invention, the housing 4 of the working lamp is made of metal and can be used to prevent falling. After 10 drop tests at 1m and 2m respectively, the working lamp was not damaged at all, and the anti-drop test can reach IK07.

[0048] In an optional embodiment, the soft plastic 1 and the inner shell 2 are integrally formed by in-mold injection molding.

[0049] like Figure 1 As shown, the soft plastic and the inner shell 2 are integrally formed by in-mold injection molding. In-mold injection molding has good bonding properties to various plastics and metals. After injection molding, the soft plastic 1 and the inner shell 2 can be effectively sealed, moisture-proof, waterproof and dust-proof.

[0050] In an optional embodiment, it also includes: a lens mounting hole 60; the soft plastic 1 and the front side of the inner shell 2 are correspondingly provided with the lens mounting hole 60 for placing a lens mounting ring 61; the inner surface of the lens mounting hole 60 is threadedly connected to the outer surface of the lens mounting ring 61; the lens mounting hole 60 and the lens mounting ring 61 are tightened and sealed using a special fixture.

[0051] In the present invention, the inner surface of the lens mounting hole 60 is threadedly connected to the outer surface of the lens mounting ring 61, and the lens mounting ring 61 is reinforced and tightened in the lens mounting hole 60 using a special fixture, which can ensure good sealing performance between the two and enhance the waterproof performance of the work light.

[0052] In an optional embodiment, it further comprises: a lens 62 ; the inner surface of the lens mounting ring 61 and the lens 62 are butt-jointed and sealed with an O-ring 7 .

[0053] In the present invention, the lens 62 is fixedly sealed with the inner surface of the lens mounting ring 61 by the O-ring 7, so as to achieve waterproofing; further, the material selection of the O-ring 7 will also directly affect the sealing performance and waterproofing performance of the work light. In the present invention, the material of the O-ring 7 is also not limited, as long as the waterproofing performance and sealing performance of the O-ring 7 meet the standard.

[0054] In an optional embodiment, it also includes: a radiator 9; radiator mounting holes are correspondingly provided on the back sides of the outer shell 4 and the inner shell 2, and the radiator 9 partially passes through the radiator mounting holes and partially abuts against the outer surface of the outer shell 4, and is sealed and fixed by a second sealing ring 8.

[0055] The work light will generate heat when working, and the heat needs to be discharged in time, otherwise it will damage the work light, reduce its service life, or even fail to operate normally. Therefore, the present invention is provided with a radiator 9, which partially passes through the radiator mounting hole and partially abuts against the outer surface of the housing 4, and the heat generated during operation is discharged through the radiator 9. Among them, a rear cover plate 26 is provided at the bottom of the radiator 9, and the rear cover plate 26 is fixedly connected to the radiator 9 by screws; this design ensures that the work light can dissipate heat well while working, and guarantees the service life of the work light as much as possible.

[0056] Furthermore, in the present invention, the back of the outer shell 4 is not completely empty, and therefore, a radiator mounting hole is provided on its back corresponding to the back of the inner shell 2, and the radiator 9 is fixedly connected to the radiator mounting hole through the second sealing ring 8, so as to achieve waterproofing; specifically, the material selection of the second sealing ring 8 will also directly affect the sealing performance and waterproofing performance of the work lamp. In the present invention, the material of the second sealing ring 8 is also not limited, as long as the waterproofing performance and sealing performance of the second sealing ring 8 meet the standard.

[0057] In an optional embodiment, a charging socket is provided at the top of the inner shell 2 and the soft plastic 1 , and the charging socket is sealed by a soft plastic cover plug 10 .

[0058] The inner shell 2 and the top of the soft plastic 1 are provided with charging sockets. If they are not covered, dust will enter and the work light will be dampened by contact with air, which will damage the work light and directly cause the work light to fail to operate normally. Therefore, the present invention designs a soft plastic cover plug 10 to cover the charging socket, thereby achieving the waterproof performance of the work light, and the overall waterproof performance of the work light can reach IP54.

[0059] A large amount of heat is generated when the work light is working. Poor heat dissipation will seriously affect the normal operation of the work light. In order to ensure the normal operation of the work light, the present invention further designs the radiator 9.

[0060] In the present invention, the radiator 9 is made of brass, which has good heat dissipation performance. Furthermore, the radiator 9 can also be made of copper, which is pure copper, and the heat dissipation effect of pure copper is better than that of brass. In the present invention, the material selection of the radiator 9 only needs to meet the heat dissipation standard. Furthermore, the radiator 9 is coated with a graphene coating, which has good thermal conductivity, so coating the graphene coating can enhance the heat dissipation effect of the radiator 9.

Among them, a rear cover plate 26 is provided at the bottom of the radiator 9, and the rear cover plate 26 is fixedly connected to the radiator 9 by screws; the rear cover plate 26 ensures that the fan in the radiator 9 or the brass block 25 coated with the graphene coating does not leak out.

[0063] In an optional embodiment, the work light further includes: a reflective cup 11 and a light source chip 12; the lens 62, the reflective cup 11, the light source chip 12, and the heat sink 9 are stacked and fixed in sequence; the light source chip 12 is fixed in the circuit board 13; the circuit board 13 is fixed in the positioning plate 14; the positioning plate 14 is fixed in the inner shell 2.
