[0028] In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first" and "second" are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present utility model, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0029] In the present invention, unless otherwise clearly defined and specified, the terms "installed", "connected", "connected", "fixedly connected" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0031] Due to the high temperature of mining lamps, the reflectors, bases and other parts of traditional mining lamps are usually fixed with metal screws. However, the fins of the heat sink itself are relatively thin, which makes it easy for the screws to slip when fixing, and the lampshade cannot be accurately locked, which may lead to poor stability in the assembly of the lamp. In addition, the screw locking operation is relatively complicated, requiring multiple rotations and adjustments, which requires a high level of skill for the installers, resulting in low production efficiency and difficulty in quality control of mining lamp products.

[0032] In order to solve the technical defects of existing mining lamps, the technical solution of the present application provides a mining lamp solution that uses expansion rivets to quickly complete the assembly of heat dissipation fins with reflectors, bases and other components. Figure 1-5 The utility model scheme is further elaborated and illustrated.

[0033] The present application provides a mining lamp, referring to Figure 1The industrial and mining lamp includes a reflector 1, a diffuser 2, a light source board 3, a radiator 4 and a back cover 5 which are fixedly connected in sequence. The reflector 1 is a cover body which is open at both ends and gradually converges from bottom to top. The lower end of the reflector 1 is an expansion end, and the upper end is a convergence end. The convergence end of the reflector 1 is provided with a first through hole 11, and the reflector 1 is fixedly installed below the radiator 4 through an expansion rivet 6 penetrated inside the first through hole 11. The back cover 5 is provided with a second through hole 51, and the back cover 5 is fixedly installed above the radiator 4 through an expansion rivet 6 penetrated inside the second through hole 51. The top and bottom of the radiator 4 are provided with third through holes 41 for fixing the expansion rivets 6. The number of the first through hole 11, the second through hole 51 and the third through hole 41 is determined according to actual needs. This mining lamp uses expansion rivets 6 to quickly complete the assembly of the heat sink fins, the reflector 1, and the base. In actual operation, it is only necessary to press the front end of the expansion rivet 6. The compression of the front end of the expansion rivet 6 and the expansion of the rear end cause radial pressure to be generated, thereby clamping the materials together to form a stable connection between the components. This solution can not only simplify the installation operation and improve the production efficiency and quality of mining lamp products, but also have temperature tolerance and mechanical strength, which is conducive to enhancing the safety and stability of mining lamp operation. Optionally, the expansion rivet 6 uses nylon rivets, plastic rivets, or other rivet parts that can deform the material by pressing to generate radial pressure to form a stable connection between the components.

[0034] In one embodiment of the present application, reference Figure 3 The reflector 1 is fixedly mounted on the bottom of the radiator 4 by an expansion rivet 6. The expansion rivet 6 includes a male plug-in 61 and a female sleeve 62 matching the male plug-in 61. The male plug-in 61 includes a nail cap and a plug rod fixed at the bottom of the nail cap. The female sleeve 62 includes at least two supporting blades 621. The supporting blades 621 extend and protrude into the sleeve and are provided with a resistance portion. The plug rod is passed through the female sleeve 62 and the plug rod wall presses against the resistance portion and opens the supporting blades 621 outward to lock the components. Optionally, the female sleeve 62 is provided with four supporting blades 621; the plug rod is provided with a slot sunken toward the center of the plug rod corresponding to the resistance portion, and the resistance portion of the supporting blade 621 can be limited by the slot to avoid relative sliding between the male and female heads, thereby enhancing the mechanical strength of the expansion rivet connection between the components.

[0035] In one embodiment of the present application, reference Figure 1 A connecting portion 12 is integrally formed at the convergent end of the reflector 1.

On the one hand, the heat sink 4 realizes ventilation and heat exchange through the fourth through holes 121 provided in the connecting portion 12, and can quickly transfer the internal heat of the heat sink 4 to the external environment, thereby improving the heat dissipation efficiency; on the other hand, the fourth through hole 121 is not compatible with the specifications of the expansion rivet 6, so that the expansion rivet 6 cannot be installed inside the elliptical through hole. Through this foolproof design, the expansion rivet 6 can be correctly installed at the preset position.

[0038] In one embodiment of the present application, reference Figure 1 The back cover 5 is also provided with a fifth through hole 52, which is a circular through hole with a diameter smaller than the diameter of the expansion rivet 6 or an elliptical through hole with a short axis length smaller than the diameter of the expansion rivet 6. The number of the fifth through holes 52 is determined according to the heat dissipation needs. The fifth through hole 52 opened in the back cover 5 and the fourth channel opened in the connecting portion 12 can form an air duct, thereby accelerating the air convection and heat exchange between the radiator 4 and the outside world, thereby improving the heat dissipation efficiency.
