Optionally, the light box in some embodiments may be implemented as an emergency lighting light box; therefore, in some of the following embodiments, the emergency lighting light box (light box for short) may be used as an example to describe the light box in a more specific and more specific manner. description.

In another alternative, the fixing plate extends from the inner side of the bottom wall to the upper wall and/or lower wall and/or the side wall; the insulating plate, the fixing plate and the fixing plate are all It is integrally fixed on i) the bottom wall and ii) the upper wall and/or lower wall and/or side wall, and the column is fitted/riveted in the through hole. If the insulating board, the wire fixing board and the fixing board are injection molded during the manufacturing process, the insulating board and the fixing board are covered on the inner side of the bottom wall, and the space between the bulge of the wire fixing board and the bottom wall, the insulating board and the fixing board themselves That is to say, it has a certain adhesion to the inside of the bottom wall, and the riveting/fitting structure of the column in the through hole is also integrally formed on the Among the through holes, the head of the cylinder has a larger size, which is stuck to the edge of the through hole, thereby further enhancing the firmness of the combination between the "insulating plate and the fixing plate" and the bottom wall. Therefore, this new structural design of both the insulating plate and the fixing plate made of plastics "closes/covers on the inner wall of the box as a whole, and the column on it is embedded/riveted in the through hole" makes It is possible to automatically complete the "integral injection molding assembly of the insulating board, the fixing board and the fixing board to the inner wall of the box" by means of injection molding, or "the hot-melt riveting connection of the prefabricated part on the through hole", etc., instead of It is limited to fixing methods such as screws and corresponding manual assembly/manufacturing in the prior art.

In some embodiments of the light box, through the fixed position penetrating the box body, the protrusion integrally extended on the fitting part is received, and a fixed connection is formed between the two, so that the fitting part is assembled on the box body. Since the protruding part integrally protrudes from the surface of the fitting, the connection and assembly between the fitting and the box body does not require a third separate component such as screws. The assembly parts are reduced, the assembly structure is simplified, it is more conducive to automatic assembly, and the assemblability/manufacturability of the light box is improved.

Especially in some preferred embodiments, the fixing position is implemented as a through hole, penetrating through the box wall of the box body. The protrusion extends into the through hole, and the head of the protrusion protrudes outside the through hole through the through hole; the head extends along the wall of the box body to the periphery of the through hole , the size of the head is larger than the diameter of the through hole, and is clipped to the edge of the through hole.

The above-mentioned "riveting" structure in which the protrusion passes through the through hole and extends, can realize the flat installation of the plate-shaped assembly on the inner wall of the box, and the assembly does not need to cover the edge of the box. It can be firmly combined with the flat inner wall of the box body. In addition, the matching structure between the above-mentioned through hole and the column is also very convenient to introduce heat riveting, injection molding and other methods to assemble between the assembly and the box during the manufacturing process of the light box. The covering force of the fittings on the inner wall of the box and the covering force of the cylinder on the edge of the through hole" can form the relative fixation between the fitting and the box wall, and the head of the raised part is extended to be larger than the diameter of the through hole to snap In the through hole, the assembly is more firmly installed on the box wall. Alternatively, a press-fit can be achieved between the protrusion on the fitting and the fixing position by applying mechanical pressure, and the two are connected/clamped together by the stress generated by pressing the protrusion into the fixing position. Therefore, with the help of the new structural design of "integrally formed on the raised part on the fitting and the fixing position on the box" in these embodiments of the present application, it is more conducive to the automatic assembly/manufacturing of the fitting on the box , improving assembleability/manufacturability.

Assemblies such as connecting plates, insulating plates, fixing plates, and fixing plates are fixed with convex and concave cooperation with the bottom wall or box wall in some preferred examples. This structural design of convex and concave cooperation can allow the use of in-situ casting ( In-mold casting) and other injection molding methods can be completed in an automated process, especially for the structure of the integrated connection of the insulating board, the fixing board, and the wire fixing board, which is more convenient to manufacture. Compared with the screw fixing method in the prior art, this The technical solutions of these embodiments of the application greatly improve the manufacturability and assemblability of the light box. Especially in some embodiments, the raised part and the fixed position are respectively implemented as a raised cylinder and a through hole on the box body, and the head of the cylinder extends through the through hole to the outside of the box body and extends to be larger than the through hole. The aperture of the hole, this structural design, allows the column to be directly processed into the through hole of the box by using plastic raw materials for in-situ casting during the manufacturing process of the light box, thus greatly improving the efficiency of the light box and lamps. Manufacturability and/or Assemblability.

In addition, in some preferred embodiments, since the light box is a box structure formed by bending a cross board, most parts of the box, such as through holes, hanging installation positions, etc., can be aligned with the board before bending. Press processing is performed, and the manufacturing efficiency is high. However, some boxes in the prior art have four walls with an integral connection structure. The through holes in this structure, etc., all need to be stamped after the integral connection structure of the box is stretched and formed, so as to avoid Deformed due to stretching, this integrally connected box structure is difficult to manufacture and has a high rate of defective products. Therefore, the new design of the light box with a bent structure proposed in some embodiments of the present application has better manufacturability.

The mounting hole 222 communicates with the port 596, thereby saving space on the box wall, or allowing the light box to have a thinner structure.

The assembly further includes a fixing plate 16' and a fixing member 164';

The protruding part 1141 and the through hole 119-1 are arranged on the fixing plate 16' and the bottom wall 1110 correspondingly.

The raised portion 1141 is distributed on the surface of the lamp holder 113, the fixing plate 16', and the fixing piece 164'. The through holes 119-1 are correspondingly arranged at the installation positions of the lamp holder 113, the fixing plate 16', and the fixing piece 164' on the box wall.

For example, the fixing member 164' spans the bottom wall 1110 and one or more of the four

walls

1112, 1111, 1113, and is relatively fixed thereto. Wherein, the protruding portion 1141 and the through hole 119-1 are correspondingly arranged on i) the fixing member 164' and ii) the upper wall or the lower wall. Through the fixed connection between the raised portion 1141 and the through hole 119-1, the fixing piece 164' is fixed to a) the bottom wall 1110 and b) the upper/lower wall from the inside of the light box.

Of course, similarly, the protruding portion 1141 and the through hole 119 - 1 are also correspondingly arranged around the peripheral portion of the lamp holder 113 and the installation hole 222 .

It should be noted that in some of the following embodiments, since the size of the fixing plate is relatively large, and it can be divided into several parts such as insulation, fixing, and wire fixing, in these embodiments, the fixing plate may also be The several parts included are called insulation board, fixing board, wire fixing board and so on. The fixing plate in these embodiments, because it is used to fix the box body of the bent structure, thereby strengthening the structural strength of the box body, so, for this part of the fixing plate in the following embodiments, especially when it is in the When it physically exists independently, it may also be referred to as a fixing piece in some of the above-mentioned other embodiments.

Figures 1-8 mostly take emergency lighting lamps/light boxes as an example, and are structural schematic diagrams of the assembly of various boards in the light box as assembly parts to the box body, and also show the interior of such light boxes/lights from different perspectives. external structure. Figures 9 and 10 show some boards used for bending to form a box.

The light box in the embodiment shown in Fig. 1-Fig. 8 is implemented as an emergency lighting light box (abbreviation: light box), and a more specific and scene-based description of the light box will be given as an example. However, it should be understood that the protection scope of this application also covers related technical solutions in other products such as emergency sign lamps, emergency sign lamp housings, and emergency sign light boxes. allow.

The head 777' extends along the box body 111 to the periphery of the through hole 119' (not shown in Figure 17). In this way, the size of the head 777' and the fitting 0023 are larger than the diameter of the through hole 119', and the head 777' is stuck The edge of the hole 119' is connected. Thereby, the protrusion 1141' forms a (similar) riveted/riveted structure to the through hole 119'.

It should be noted that "integrated with", "integrally connected", "integrally formed", "integrated", "integrally", "integral..." in some embodiments mean that they are manufactured together at the same time, that is, as the same assembly , rather than two separately manufactured assemblies that are subsequently joined together. In addition, the protruding part may also be referred to simply as: a protruding part, and in some other embodiments, it is used as a fixed end and adapted to the fixed position, so that a fixed connection structure is formed between the two.

Optionally, in the light box of some embodiments, the protrusion 1141' extends into the through hole, and the head of the protrusion protrudes out of the through hole 119' through the through hole. The head 777' extends along the outer wall of the box body 111 toward the periphery of the through hole 119', the size of the head 777' is larger than the diameter of the through hole 119', and the edge of the through hole 119' is engaged. Thus, the fitting 0023 is fitted to the inner wall of the box body 111 . Under this structure, a higher degree of mechanical coupling between the components and the box body can be formed, thereby further improving the firmness of the assembly part 0023 on the box body 111 .

Related embodiments of the present application will be described in detail below with reference to FIG. 2 , and FIG. 11 to FIG. 15 .

As shown in Figure 1, the emergency lighting light box of this embodiment includes:

A box body 111, the box body 111 includes a bottom wall 1110 and a plurality of

walls

1111, 1112, 1113, the plurality of walls stand up from the bottom wall 1110 along the periphery of the bottom wall 1110 and enclose;

insulation board 16;

The light box 111 also includes a protruding portion, such as a post 1141 , and a fixing position, such as a through hole 119 . The pillars 1141 and the through holes 119 are arranged on the insulating plate 16 and the bottom wall 1110 correspondingly, and the pillars 1141 are connected to the through holes 119, thereby fixing the insulating plate 16 inside the bottom wall 1110;

The circuit board 162 is clamped on the insulating board 16 .

Optionally, the emergency lighting light box in some embodiments further includes a wire fixing plate 163 and/or a fixing plate 164 .

A wire hole 904 is defined on the wire fixing plate 163, and a first wire clamp 901 is provided. The first wire clamp 901 is set opposite to the wire hole 904 or the edge of the wire hole 904 to accommodate wires therebetween.

The pillars 1141 and the through holes 119 are correspondingly arranged on the fixing plate 164 and the bottom wall 1110 , and the fixing plate 164 is fixed inside the bottom wall 1110 through the connection between the pillars 1141 and the fixing positions 119 .

Optionally, in some embodiments of the emergency lighting light box, the first part 9011 of the first cable buckle 901 stands up from the edge of the wire hole 904, and the second part 9012 of the first cable button 901 faces toward the wire hole 904 or the wire hole 904. The edge of the wire hole 904 is bent and extended, and the second portion 9012 is spaced opposite to the wire hole 901 or the edge of the wire hole to clamp the wire. Preferably, the edge of the wire passing hole 904 protrudes from the wire fixing plate 163 , so that it is more convenient to cooperate with the first wire locking buckle 901 to fasten the wire passing between the two.

Optionally, in the emergency lighting light box of some embodiments, the insulating plate 16, the fixing plate 163 and the fixing plate 164 are sequentially arranged on the bottom wall 1110, and the insulating plate 16, the fixing plate 163 and the fixing plate 164 are three-in-one connection; the structure of the integral connection of the three makes it possible for the three to be integrally assembled on the bottom wall 1110, thereby improving the assemblability of the insulating plate 16, the fixing plate 163 and the fixing plate 164 in the box, especially When the three

boards

16, 163, 164 are integrally formed on the bottom wall 1110 through in-situ casting of plastic materials, they have physically independent structures compared to the three boards. The manufacturability of the light box is improved. And, the integrally connected structure of the three boards also improves the overall mechanical coupling between the three

boards

16 , 163 , 164 and the box body 111 , thereby further strengthening the overall structural strength of the box body 111 .

Optionally, in the emergency lighting light box of some embodiments, a second wire clamping buckle 902 is also provided on the wire fixing plate 163, and the first wire clamping buckle 901 and the second wire clamping buckle 902 are bent and extended in a direction transverse to the wires, As shown in Figure 15, as shown in Figure 15, since two points determine a straight line, the two

clips

901, 902 can determine the basic direction of the wire, and basically define a passage for the wire, and the layout of the two dislocations makes It is easier for electric wires to be placed in the wire-passing channel defined by the first wire clamp 901 and the second wire clamp 902, supplemented by a structure that bends and extends in the direction transverse to the wire, then the first wire clamp can be 901 and the second wire clamp 902 can partially wrap around different positions on the wire from the side of the wire along the direction of the wire, so as to form a more stable fixing structure for the wire.

Optionally, in some embodiments of the emergency lighting light box, a first raised area is formed on the wire fixing plate 163, and the first part 9011 of the first wire buckle 901 is located on the first raised area 905 or at the top of the first raised area 905. At the periphery, the second part 9012 of the first cable buckle 901 cooperates with the top of the first raised area 905 to clamp the wires. The wire hole 904 is opened on the first raised area 905 , and the projection of the second part 9012 of the first cable buckle 901 to the bottom wall 1110 covers the edge of the wire hole 119 and the periphery of the first raised area 905 . In this way, after the wires are clamped by the second part 9012 and the top of the first raised area 905, the wires are bent out of the wire passing hole 904 on the first raised area 905 immediately, and the direction of the wires is changed. In the small space on the first raised area 905, the structure continuously forms a clamping structure for the electric wire and a structure for forcing the electric wire to bend, which is beneficial to form a more stable fixation for the electric wire.

Optionally, in some embodiments of the emergency lighting light box, a second raised area 903 is formed on the wire fixing plate 163, and the second locking wire buckle 902 is located on the periphery of the second raised area 903. The second locking wire buckle 902 The structure is similar to the first cable buckle, its first part (not marked in the figure) stands up from the wire fixing plate 163, the second part of the second cable buckle 902 is bent by the first part, and the second cable buckle 902 The projection of the second part 9022 of the second part 9022 to the bottom wall 1110 covers the periphery of the second raised area 903, and cooperates with the edge of the second raised area 903 to fasten the wires. In the wire passageway, when the wire passes between the second wire clamp 902 and the flat wire fixing plate 163 and continues to extend to the edge of the second raised area 903 , it is forced to bend. Therefore, this structure has a better fixing effect on the electric wire. Preferably, the first raised area 905 is located on the second raised area 903 , the two raised areas and the wire holes etc. are relatively compact in overall structure and effectively utilize the internal space of the light box.

The fixing plate 164 extends from the inner side of the bottom wall 1110 to one or more of the upper wall 1112 , the lower wall 1113 and the side wall 1111 , and is relatively fixed to the one or more box walls. As shown in Fig. 2 and Fig. 12, the fixing plate 164 in this embodiment extends across the bottom wall 1110 and the lower wall 1113, and is fixed on the bottom wall 1110 and the lower wall 1113, thereby strengthening the gap between the bottom wall 1110 and the lower wall 1113 structural strength. Moreover, by means of the connection of the fixing plate 164, the coupling/fixed connection between the bottom wall 1110 and one or more of the upper wall 1112, the lower wall 1113 and the side wall 1111 is strengthened, which is very important for other embodiments. The box body formed by bending the ends of the glyph-shaped board further strengthens the overall structural strength of the box body.

The bottom wall 1110 defines a wire outlet hole 904' corresponding to the position of the wire passage hole 904.

Optionally, in some embodiments of the emergency lighting light box, the raised portion and the fixing position are not limited to being implemented as a column 1141 and the through hole 119, and in some alternative solutions, the raised portion and the fixing position can also be implemented as Interfitting male and female snaps. Or, in still some alternative solutions, the raised portion can be implemented as a protrusion on the insulating plate 16 or the fixing plate 164, and the fixing position can be implemented as a recess on the bottom wall 1110; or, in some other alternative solutions Among them, the protruding portion can also be implemented as a protrusion on the bottom wall 1110 , and the fixing position can be implemented as a recess on the insulating plate 16 or the fixing plate 164 correspondingly. Compared with the prior art, the convex-concave connection between the insulating plate 16 and the bottom wall 1110 in these embodiments of the present utility model, no matter whether the insulating plate 16 is integrally formed on the bottom wall 1110 by injection molding, or the insulating plate 16 is integrally formed on the bottom wall 1110 by means of external force. The post 1141 as the protrusion is pressed into the through hole 119 as the fixing position, which is more convenient and improves the assemblability. The connection between the fixing plate 164 and the bottom wall 1110 is also the same and will not be repeated here.

Wherein, the protruding part includes the insulating plate 16 and the protruding column 1141 on the fixing plate 164, the concave part includes the through hole 119 penetrating the bottom wall 1110, and the column 1141 extends into and is fixed in the through hole 119 to form a fitting/riveting The insulating plate 16 and the fixing plate 164 are integrally attached to/covered on the inner side of the bottom wall 1110 . Wherein, the abutting structure, in addition to the direct surface contact between the insulating plate 16 and the bottom wall 1110, can also be implemented as a close and close structure, that is, it does not rule out the presence of Small gaps, but only connected to each other at the raised part and the fixed position.

buckle plate positions

1611, 1612 are arranged symmetrically and/or oppositely on these buckle plates 161, and Two opposite ends (not marked in the figure) on the circuit board 162 are matched or correspond to. Because the buckle plate 161 stands up from the insulating plate 16, after the circuit board 162 is installed on the buckle plate position, there is no contact between the circuit board 162 and the insulating plate 16, which strengthens the relationship between the two. Insulation isolation between. Wherein, the circuit board 162 may be spaced apart from the insulation board 16 due to the existence of the stop portion 1612 in the following embodiments.

Further optionally, in some embodiments of the emergency lighting light box, the

walls

1111, 1112, 1113; and

The light box also includes a connecting plate 114 filling the gap 115 and connecting two adjacent walls among the four

walls

1111 , 1112 , 1113 , such as the upper wall 1112 and the side wall 1111 .

The cylinders 1141 are arranged at both ends of the connecting plate 114. Correspondingly, the through holes 119 are opened on the two

opposite ends

edges

11121 and 11111 of the notch 115 to form the corners of the box body.

The periphery of the cover body 15 forms a fastening edge extending toward the port, on which a first buckle 117 is arranged, and a second buckle is arranged on the periphery of the port, and the cover 15 passes through the second buckle and the first buckle 117. Snap fit to cover the port, as shown in Figure 4, Figure 5, Figure 7, and Figure 8.

The four

walls

1111, 1112, 1113 include the opposite upper wall 1112 and the lower wall 1113, which are formed by bending the plate body 111' or the opposite ends 1112', 1113' of the plate body 111' in the longitudinal direction L1. The four

walls

1111, 1112, 1113 also include two opposite side walls 1111, and the two opposite ends 1111' of the plate body 111' in the transverse direction T1 are bent toward each other; the four

walls

1111, 1112, 1113 are formed along the body 1110' The periphery of the body 1110 ′ is bent and vertically erected towards the inner side of the main body 1110 ′, and two adjacent walls are spaced apart from each other to form a gap 115 .

In the above embodiment, the bottom wall 1110 of the box body 111 and the four

walls

1111, 1112, 1113 are surrounded by four protruding ends 1111', 1112', 1113' around a substantially cross-shaped plate body 111' The main body 1110' (defined by the dotted outline in FIG. 9 ) is formed by bending towards each other. As shown in FIG. ', 1113'. On the cross-shaped plate body 111', two adjacent ends are not directly connected, for example: the corner 115' on the body 1110' between the end 1112' and the end 1111' is spaced apart from each other , no direct contact occurs, thus, when the four ends 1111', 1112', 1113' are bent towards each other to form the box body 111, the adjacent two walls of the four

walls

1111, 1112, 1113 of the box body 111 Between, there will be a gap 115. Those skilled in the art can understand that: the four ends 1111', 1112', 1113' are bent towards each other, which means that the four ends are bent toward the same side/inside of the plate body.

Wherein, two opposite ends 1112', 1113' of the plate body 111' in the longitudinal direction L1 are bent to form an upper wall 1112 and a lower wall 1113. Two opposite end portions 1111' of the plate body 111' in the transverse direction T1 are bent towards each other to form two side walls 1111 of the box body.

Certainly, the box body of this bent structure can also be constructed based on another plate body 111 ″ as shown in FIG. "Four protruding ends 1111', 1112', 1113' around. On this plate body 111", two adjacent ends are directly connected, for example: between the end 1112" and the end 1111", the corner 115" on the body 1110" is in direct contact The four ends around this cross-shaped plate 111" are bent towards each other to form the four walls of the box, and at the far end (that is, the direction away from the body of the plate) encloses one of the boxes. open ports. In the upper and lower walls and side walls of the box body formed after the four ends are bent, the opposite ends (not shown) on two adjacent walls are basically in direct contact with each other, or Due to the plate body processing technology or tolerance, only a small interval (not shown in the figure) is reserved between the opposite ends of the adjacent two walls. This small interval is compared with that in Fig. 2 The notch 115 is negligible, that is, on the box body formed by bending the plate body in Figure 10, two adjacent walls of the four walls are joined to each other, and a separate connecting plate is not required To fill and connect between two adjacent walls of this kind of box. Instead, the adjacent two partition walls can be further connected and fixed by welding connection, gluing connection or adhesive connection. Typical joining techniques include welding (eg, ultrasonic welding), gluing, sizing, pressure heat fusion, and the like. Certainly, a structure in which two adjacent walls are connected to each other indirectly through a separate connecting plate may also be used. This has been described and illustrated in other embodiments, and will not be repeated here. In these embodiments, two adjacent walls are adjacent to each other, or are separated from each other to form a gap therebetween, rather than integrally connected. This new structural design makes the box structure not limited to stretch forming, but can also be bent and formed, which improves manufacturability.

In some of the above or following embodiments, as shown in the figures, adjacent two of the four walls of the box body 111 are not coplanar, for example perpendicular to each other. Correspondingly, the connecting plate 114 is shaped as: two adjacent two of the four walls, such as an arc-shaped connecting plate between the upper wall and the side wall, and between the lower wall and the side wall, as shown in FIGS. 2 and 3 , the arc shape of the connecting plate located at the corners of the box may also be referred to as rounded corners in other embodiments. Alternatively, the connection plate 114 can also be shaped as a right-angle connection plate, which is not shown in the figure.

The box body is made of metal and is suitable for bending. The plate body is a color-coated steel plate. Compared with plastic materials, the color-coated steel plate has higher structural strength. The connection plate is preferably made of plastic. Compared with metal materials, the connection plate made of plastic is easier to be processed to the gap, which improves the manufacturability of the light box/luminaire. Fill the connecting plate into the gap and connect the edges of the gap to form a more complete box and enhance the structural strength of the box. If the box itself and the connecting plate are made of plastic materials, the wall of the box and the connection The boundaries between the plates are already unclear, and if the box itself is made of metal materials such as color-coated steel plates, and the connecting plates are made of plastic materials, the boundaries between the walls of the box and the connecting plates are clearer. But above two kinds of situations all belong to the protection domain of the present application. It should be understood that the relevant description is only used to illustrate the present application rather than limit the scope of the present application. The protection scope of the present application is limited by the scope of the claims, and other embodiments all fall within the scope of the claims.

Optionally, the light box also includes a raised portion 1141, the raised portion is formed at both ends of the connecting plate 114; the two

adjacent ends

11121, 11111 of the two adjacent walls, the recess forms a fixed position, and the raised portion part 1141 is adapted; the connection between the raised part 1141 and the fixed position is one of injection molding connection, molding connection, tight fit, press fit, convex-concave fit, chemical bonding, heat riveting or buckling.

Further optionally, as shown in FIG. 7 and FIG. 8 , the raised portion 1141 is a cylinder, and the fixed position is a through hole 119 passing through the box, and the cylinder extends into the through hole 119, and the head 777 of the cylinder passes through The through hole 119 protrudes outside the through hole 119; the head 777 extends to the periphery of the through hole 119 to be larger than the diameter of the through hole 119. In terms of local shape, the cross section of the connection structure formed by the column in the through hole is approximately The "H" shape snaps to the edge of the through hole 119 , as shown in FIG. 8 . From the overall process of the manufacturing method, the box body 111 is punched to form a through hole 119, and then the box body 111 is placed in an injection molding machine (not shown in the figure). When the plastic connecting plate 114 is formed, the plastic material also flows into the through hole 119. The hole 119 fixes the connecting plate 114 of plastic on the through hole 119. The connecting section between the connecting plate 114 and the through hole 119 forms an "H" shape, so as to clamp the edge of the through hole 119 . Similarly, the connection structure between other mounting parts such as fixing plates, fixing parts, lamp holders and the box body and the through hole of the countersunk head can also be realized by the above method.

Optionally, for a connection structure similar to riveting/anchoring between a) the connection plate and its protrusions and b) the through hole, the prefabricated plastic part of “integrally connected connection plate and column” can be used. It can be formed by hot melting, or it can also be formed by in-situ injection molding at the through hole of the box to form an "integrally connected connection plate and column", and at the same time, the column is also connected to the through hole.

Preferably, the connecting plate 114 can be processed on the light box by using injection molding process, but the prefabricated thermoplastic connecting plate 114 can also be connected to the

ends

11111, 11121 of the two

adjacent walls

1111, 1112 through hot-melt connection. In hole 119.

Optionally, the light box 11 also includes a lamp base 113, and an installation hole 222 is opened on the upper wall to accommodate the lamp base 113; the lamp base is integrally connected to the connecting plate 114 through a connecting piece 888, such as the combination of the lamp base and the connecting plate is If it is prefabricated separately, the integrated structure enables the combination of the two parts to be integrally assembled on the box body, which improves the assembly efficiency and the assemblability of the light box. Moreover, the degree of mechanical coupling between the lamp base and the connecting plate is higher, and the structural stability is better, and since the connecting plate is connected with the upper wall and the side wall, the lower wall and the side wall, the upper wall and the side wall, the lower wall and the side wall are also connected. A higher degree of mechanical coupling between the lower wall and side walls results in better structural stability.

The connection plate 114 filled in the gap 115 in some of the above embodiments is not only enclosed with the upper wall 1112, the lower wall 1113, and the side wall 1111 to ensure the airtightness of the box, but also connected separately along the circumference of the port of the box. The adjacent parts on the two adjacent walls, such as the end portion 11121 and the end portion 11111, are defined. In this way, the adjacent walls are fixedly connected through the connecting plate, and the four walls are connected as a whole through the connecting plates at the four corners, which strengthens the structural strength between the walls of the bending structure and the box body overall structural strength. At the same time, the connecting plates in the gaps at the four corners also form corners of the box perpendicular to the bottom wall 1110, and the corners may be rounded or right-angled. The bottom wall of the box is equivalent to the body on the board in some other embodiments, therefore, it is also called the body in the context of describing the board.

In addition, if the structural strength of the box body is to be further strengthened, a fixing plate 164 can also be provided in some embodiments, and the raised portion 1141 is also arranged on the fixing plate 164, and the fixing positions are correspondingly distributed on the bottom wall 1110, on the upper wall 1112 , the lower wall 1113 and the side wall 1111 . The fixing plate 164 is covered and fixed on a) the inner surface of the bottom wall 1110 and the inner surface of the upper wall 1112 through the protrusion 1141, or, b) the inner surface of the bottom wall 1110 and the inner surface of the lower wall 1113, or c) the inner surface of the bottom wall 1110 The inner surface and the inner surface of the side wall 1111. Because the fixing plate 164 extends along the inner wall of the box body 111 and crosses the bottom wall 1110 and one of the four walls, a higher structural strength is formed between the four walls and the bottom wall, which improves the overall structural strength of the box body .

It can be seen from the figure that the board body 111 ″ or the structure 111 formed by bending the board body 111 ″ can be called a box body. The box body 111 can be defined as a fire emergency lighting light box (or simply a light box, an emergency lighting light box) after assembling a lamp base, a connecting plate, and a cover body. After continuing to assemble lamp holders and other parts, it can be defined as fire emergency lighting fixtures (or emergency lighting fixtures, emergency lighting lamps, lamps for short).

In some embodiments, the emergency lighting fixture further includes: a lamp head 17, the bottom of which forms a ball head structure 501, as shown in Fig. 2 and Fig. 6 .

A ball socket (not marked in the figure) adapted to the ball head structure 501 is provided on the lamp base 113;

The ball head structure 501 is rotatably installed in the ball socket, and the bottom of the ball socket is provided with a first passageway (not shown in the figure), which communicates with the interior of the light box 111; and, the outside of the bottom of the ball head structure 501 is also provided with a stopper 1711 , the stopper 1711 extends into the first wire passing channel, and abuts against the edge/inner wall of the first wire passing channel as the ball head structure 501 rotates.

Through the stopper 1711 outside the bottom of the ball head structure 501, when the rotation range of the ball head structure 501 in the ball socket reaches a certain threshold, the stopper 1711 abuts against the inner wall of the first wire-passing channel to stop the rotation. Therefore, during the rotation process of the ball head structure 501 in the ball socket, it will not fall off from the lamp holder 113 due to excessive rotation range.
