Description

Technical Field

[0001] The utility model relates to the technical field of emergency lamps, in particular to a light box reinforcement structure of a double-head lamp. Background Art

[0002] Fire emergency lighting is a guarantee for safety and emergency in public places. It is a mandatory equipment for public fire protection. It has a wide range of uses and a relatively complex layout environment. It is usually installed in fire escape passages. When power outages, fire alarms, etc. occur, the lights can be automatically turned on to realize the emergency lighting function.

[0003] The existing fire emergency double-headed lamp is composed of a light box, a lamp holder and a lamp head. The lamp holder is assembled on the upper side of the light box, and the lamp head is assembled on the lamp holder. In order to increase the lighting range or light utilization rate, the lamp head can be adjusted according to the usage scenario or user needs, so that the light source of the lamp head is directed in the required direction. In order to ensure that the lamp head does not move after adjustment, the connection between the lamp head and the lamp holder is relatively tight. When adjusting the lamp head, the lamp head will drive the lamp holder to apply force to the upper side of the light box. Due to the excessively single force, the light box with thinner material will be deformed. Therefore, only light boxes with thicker material can be used on the market, which makes the prices of double-headed lamps on the market more expensive. Utility Model Content

DETAILED DESCRIPTION

[0026] The technical solution of the present utility model is further described below with reference to specific embodiments.

[0027] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, a light box reinforcement structure for a double headlight comprises: a light box 1, provided with an upper side surface 11 and a back plate 12, the upper side surface 11 being provided with a first fixing hole 13 penetrating the upper side surface 11; a reinforcement member 2, arranged below the upper side surface 11, the reinforcement member 2 being provided with a top surface 21 and a back surface 22, the top surface 21 being closely attached to the upper side surface 11, the back surface 22 being closely attached to the back plate 12, the top surface 21 being provided with a connecting portion 3; a lamp holder 4, arranged on the upper side surface 11, the lamp holder 4 being connected to the top surface 21 via the connecting portion 3 and the first fixing hole 13; a lamp holder 5, arranged on the lamp holder holder 4. By arranging a reinforcement member 2 under the lamp holder base 4 and connecting it to the reinforcement member 2 through the connecting portion 3, a connection relationship is generated between the lamp holder base 4 and the reinforcement member 2. When the lamp holder 5 is adjusted, the lamp holder 5 drives the lamp holder base 4 to apply force to the light box 1 and simultaneously applies force to the reinforcement member 2. The top surface 21 and the back surface 22 of the reinforcement member 2 can increase the force-bearing area and disperse the force to the upper side surface 11 and the back plate 12 of the light box 1, thereby achieving the purpose of reinforcing the light box 1. The structure is simple, firm, easy to assemble, and can effectively reduce product costs.

[0028] The cross-section of the top surface 21 and the back surface 22 after being connected is in the shape of a letter "7". A reinforcement portion 23 is provided between the top surface 21 and the back surface 22. The reinforcement portion 23 connects the surfaces of the top surface 21 and the back surface 22. The reinforcement portion 23 can strengthen the connection between the top surface 21 and the back surface 22, making the reinforcement member 2 stronger, thereby reinforcing the light box 1.

[0029] The upper side surface 11 and the back plate 12 are provided with reinforcing ribs 14 , which are connected to each other. The reinforcing ribs 14 can increase the connection between the upper side surface 11 and the back plate 12 , thereby improving the hardness of the light box 1 .

[0030] The lamp holder base 4 is provided with a first wire outlet hole 41, the light box 1 is provided with a second wire outlet hole 15, and the reinforcement member 2 is provided with a third wire outlet hole 23. The positions of the first wire outlet hole 41, the second wire outlet hole 15 and the third wire outlet hole 23 are adapted to each other. The first wire outlet hole 41, the second wire outlet hole 15 and the third wire outlet hole 23 can connect the power cord to the circuit board in the light box 1 and the lamp holder 5, thereby ensuring the lighting function of the lamp, and the sealing structure can effectively protect the power cord. The size of the second wire outlet hole 15 and / or the third wire outlet hole 23 is smaller than the first wire outlet hole 41. This structure can prevent the power cord from contacting the second wire outlet hole 15, thereby avoiding the second wire outlet hole 15 of the metal light box 1 from causing damage to the power cord.

[0031] The connecting portion 3 includes a second fixing hole 25 provided on the top surface 21. A fixing foot 42 is provided below the lamp holder 4. The fixing foot 42 is provided with a snap-on portion 43. The fixing foot 42 passes through the first fixing hole 13 and the second fixing hole 25. The snap-on portion 43 is provided below the second fixing hole 25, resulting in a simple structure and convenient installation. A fixing surface 26 extending toward the interior of the light box 1 is provided below the second fixing hole 25. The snap-on portion 43 is provided below the fixing surface 25. The fixing surface 25 is provided between the top surface 21 and the snap-on portion 43. The fixing surface 26 can increase the distance between the top surface 21 and the snap-on portion 42, thereby increasing the force-bearing area and improving the hardness of the product.

[0032] A reinforcement surface 44 is provided under the lamp holder 4, and the reinforcement surface 44 is arranged above the upper side surface 11. The fixing foot 42 is arranged under the reinforcement surface 44. The upper side surface 11 is provided with a first groove 16 whose shape is adapted to the shape of the reinforcement surface 44. The reinforcement surface 44 is arranged in the first groove 16. The reinforcement member 2 is provided with a second groove 27 adapted to the first groove 16, and the first groove 16 is arranged in the second groove 27. The reinforcement surface 44 can increase the force-bearing area of the lamp holder 4, and combined with the buckle portion 43, the lamp holder 4 can be more firmly assembled in the light box 1.

[0033] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
