Description

Technical Field

[0001] The utility model relates to the field of heat dissipation structures, in particular to a heat dissipation structure for outdoor work lamps. Background Art

[0002] Lighting lamps are a general term for LED lamps, which refer to appliances that can transmit light, distribute and change the light distribution of LED light sources, including all parts and components required to fix and protect LED light sources in addition to LED light sources, as well as line accessories necessary for connecting to the power supply. With the further maturity of LED technology, LED will achieve more and better development in the field of indoor lighting fixture design and development. There are many types of existing lighting lamps. In addition to indoor use, there are also outdoor lighting lamps, such as road lights, landscape lights, lawn lights, underground lights, wall lights, outdoor spotlights, floodlights, wall washers, etc. The use of outdoor lights is more extensive than that of indoor use. They can even be used handheld or head-mounted during outdoor activities. However, when used outdoors, in order to provide functions such as waterproofing, most outdoor lights are relatively airtight, which affects the heat dissipation of outdoor lights, which may affect the life of work lights and even burn the human body. To this end, we designed a heat dissipation structure for outdoor work lights. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a heat dissipation structure for an outdoor work light, which solves the problem that when the outdoor work light is used, most outdoor lights are relatively airtight for the sake of waterproofing and other functions, which affects the heat dissipation of the outdoor light, which may affect the life of the work light and even burn the human body.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A heat dissipation structure for an outdoor work lamp comprises a protective cover, a lamp holder is installed inside the protective cover, and a work lamp is installed on the lamp holder.

[0006] A spring assembly is installed on the left side of the bottom wall of the protective cover, an air inlet hole is opened on the right side of the bottom wall of the protective cover, a first gear is installed on the top of the spring assembly, a mounting hole is opened on the left side of the bottom wall of the protective cover, a cooling fan blade is installed inside the mounting hole, and a second gear meshing with the first gear is installed on the top of the cooling fan blade.

[0007] A third gear is installed at the bottom of the clockwork assembly, a fourth gear meshing with the third gear is rotatably connected to the bottom of the protective cover, a winding wheel is fixedly connected to the bottom of the fourth gear, and a pulling rope is wound around the winding wheel.

[0008] Furthermore, a rotating shaft is fixedly connected to the bottom of the second gear, and the bottom of the rotating shaft is rotatably connected to the heat dissipation fan blades.

[0009] Furthermore, a limiting sleeve which is sleeved on the outside of the rotating shaft is fixedly connected to the inside of the mounting hole.

[0010] Furthermore, one end of the pulling rope away from the winding wheel is fixedly connected with a sealing plug, and the sealing plug is inserted into the installation hole.

[0011] Furthermore, the air inlet hole is configured to be an inverted cone.

[0012] The beneficial effects of the utility model are as follows: the clockwork assembly is first tightened, and then when released, it can drive the first gear to rotate, and then drive the second gear and the heat dissipation fan blades to rotate. When the heat dissipation fan blades rotate, they can suck out the air in the protective cover, and the external air enters the protective cover through the air inlet holes, which can speed up the air convection inside and outside the protective cover, enhance the heat dissipation effect of the outdoor lamp, protect the work lamp, and prolong its service life.

[0016] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] A spring assembly 4 is installed on the left side of the bottom wall of the protective cover 1, an air inlet hole 5 is opened on the right side of the bottom wall of the protective cover 1, a first gear 6 is installed on the top of the spring assembly 4, a mounting hole 7 is opened on the left side of the bottom wall of the protective cover 1, a heat dissipation fan blade 8 is installed inside the mounting hole 7, and a second gear 9 meshing with the first gear 6 is installed on the top of the heat dissipation fan blade 8. The spring assembly 4 is first tightened, and then when it is released, it can drive the first gear 6 to rotate, and then drive the second gear 9 and the heat dissipation fan blade 8 to rotate. The heat dissipation fan blade 8 can suck out the air in the protective cover 1 when rotating, and the external air enters the protective cover 1 along the air inlet hole 5, which can accelerate the air convection inside and outside the protective cover 1, enhance the heat dissipation effect of the outdoor lamp, and protect the work lamp 3 to extend its service life.

[0019] A third gear 10 is installed at the bottom of the spring assembly 4, and the bottom of the protective cover 1 is rotatably connected to a fourth gear 11 that meshes with the third gear 10. The bottom of the fourth gear 11 is fixedly connected to a winding wheel 12, and a pulling rope 13 is wound around the winding wheel 12. When the pulling rope 13 is pulled, the pulling rope 13 can be unfolded and then the winding wheel 12 and the fourth gear 11 can be driven to rotate. At this time, the third gear 10 can be driven to rotate, so that the spring assembly 4 can be tightened to accumulate energy.

[0020] In another embodiment, the bottom of the second gear 9 is fixedly connected to a rotating shaft 14, the bottom of the rotating shaft 14 is rotatably connected to the heat dissipation fan blades 8, and the inside of the mounting hole 7 is fixedly connected to a limiting sleeve 15 sleeved on the outside of the rotating shaft 14. When the second gear 9 rotates, it can drive the rotating shaft 14 to rotate, and the limiting sleeve 15 can ensure that the rotating shaft 14 rotates smoothly.

[0021] In another embodiment, a sealing plug 16 is fixedly connected to one end of the pulling rope 13 away from the winding wheel 12, and the sealing plug 16 is inserted into the mounting hole 7. The air inlet hole 5 is set to an inverted cone shape. The sealing plug 16 is inserted into the mounting hole 7 to seal the mounting hole 7. The inverted cone-shaped air inlet hole 5 can prevent external water from entering the protective cover 1, thereby improving the protection effect of the outdoor lamp.

[0022] In summary, when the utility model is in use, the pulling rope 13 can be unfolded when pulling the pulling rope 13, and then the winding wheel 12 and the fourth gear 11 can be driven to rotate. At this time, the third gear 10 can be driven to rotate, so that the clockwork assembly 4 can be tightened, and then when it is released, it can drive the first gear 6 to rotate, and then drive the second gear 9 and the heat dissipation fan blades 8 to rotate. When the heat dissipation fan blades 8 rotate, the air in the protective cover 1 can be sucked out, and the external air enters the protective cover 1 along the air inlet 5, which can accelerate the air convection inside and outside the protective cover 1.
