Lamp holder and end plate integration

As shown in fig. 8, fig. 11-fig. 13, the emergency lighting lamp box of the embodiments includes:

a base 202;

a case 100 having a port; the top of the box body 100 is provided with a mounting hole 1010 for mounting the lamp holder 202;

a closure member removably closing the port to at least partially close the tank;

the lamp holder is connected to the plugging piece and extends to the mounting hole.

Here, it should be noted that: the opening port on the box body can be used for arranging a circuit board and the like in the box body, the port can be positioned at the back of the box body, can also be positioned at one side or two sides of the box body, and even can be positioned at the front of the box body, and correspondingly, the blocking piece respectively replaces the back wall, the side wall or the front wall of the box body in other embodiments. While in some embodiments of the drawings, only the port 888 and the corresponding blocking end plate are shown on one or both sides of the box 100, other modifications will not be described again due to the similarity of the structure or principle. For the case, the structure will vary depending on the location of the port, e.g., if the port is located at the back of the case, the remainder can be defined as the case after removal of the closure/back wall. If the port is located on one or both sides of the tank, the remaining portion may be defined as the tank after the side wall/closure end plate is removed. In other words, the blocking member is a detachable member in many cases, and a portion of the lamp box main body remaining after the blocking member is removed may be referred to as a box body.

In addition, the lamp holder and the plugging piece can be integrally connected, or the lamp holder and the plugging piece are manufactured respectively and then connected into a combined body. After the lamp holder base and the plugging piece form a combined body, two positions on the box body can be plugged synchronously. For example, the two positions may be substantially perpendicular portions on the box body: side ports and top wall mounting holes. Through the scheme of this embodiment, can once only assemble the part on two mutually perpendicular walls of box, improve the assemblability to a great extent. Which in the prior art requires more than two assemblies to complete.

Optionally, the emergency lighting lamp box of some embodiments described above or below further includes a connecting portion integrally connected between the lamp base 202 and the blocking member and extending toward the mounting hole 1010 to position the lamp base 202 at the mounting hole 1010, the connecting portion being substantially perpendicular to the blocking member.

Alternatively, in some embodiments of the emergency light box described above or below, the blocking member is a blocking end plate 200 (which may be simply referred to as an end plate) or a back wall of the box body (not shown).

The connecting portion is a connecting plate 201 extending from the end plate 200 or the back wall integrally away from the end plate/back wall, and on which a base 202 is formed. The lamp holder base can be located at the extending tail end of the connecting plate or in the middle of the connecting plate. The web 201 is substantially perpendicular to the end plate or the web is substantially perpendicular to the back wall. "substantially vertical" and "substantially vertical" in this and other embodiments refer to: the angle between the two is any value of [80 degrees, 100 degrees ], [85 degrees, 95 degrees ], [75 degrees, 105 degrees ], or 90 degrees.

A connection plate 201 configured to allow the lamp base 202 to be synchronously inserted into the mounting hole 1010 as the end plate 200 blocks the port 888, the length of the connection plate 201 corresponding to the distance between the mounting hole 1010 and the end plate 200.

Optionally, the mounting hole 1010 is opened in the top wall 1001 in a direction toward the port 888 to form a strip-shaped notch, in other words, the mounting hole 1010 extends in a direction toward the port 888 and is spatially communicated with the port 888, as shown in fig. 2, fig. 3, and the like.

The shape of the connecting plate 201 is approximately complementary and/or conforms to the strip-shaped gap, and the connecting plate closes/fills the strip-shaped gap of the mounting hole along with the end plate 200 blocking the port; the edge of the strip-shaped gap is inward folded 1008; the edge of the connecting plate 201 extends into the box body 100 to form the shoulder 203, and extends outwards from two sides to form the shoulder 203 to clamp the folded edge, and the shoulder structure aiming at the bending of the folded edge improves the mechanical coupling degree and the structural stability between the connecting plate and the strip-shaped notch. Furthermore, the three matching structures, i) "the edge of the connecting plate extending towards the inside of the box body" and "the edge of the strip-shaped gap or the folded edge extending inwards of the edge", ii) "the shoulder" and "the folded edge end of the strip-shaped gap", iii) "the first limiting part on the port" and "the second limiting part on the end plate" in other embodiments, respectively form the limiting/fixing of the "port and the mounting hole" and "the end plate, the connecting plate and the lamp holder" in three different dimensions (basically orthogonal) including the transverse dimension, the longitudinal dimension and the vertical dimension (not marked in the figure), so that the structural stability of the whole lamp/lamp box is enhanced. Or an extension plate 9971 which is vertically erected towards the inside of the port at the periphery of the end plate is matched, as shown in fig. 12, so that the structural stability between the port and the mounting hole and the end plate, the connecting plate and the lamp holder seat and the covering effect of the end plate on the port are further enhanced.

Moreover, due to the many-to-many mechanical coupling structure between the end plate and the port, the connecting plate and the strip notch, and the lamp holder and the mounting hole, compared with the case that the assembly is assembled to the box body only through a single component (such as the end plate) in the assembly of the end plate, the connecting plate and the lamp holder and other components, the embodiments of the application promote the overall mechanical coupling degree between a) the component assembly consisting of the end plate, the connecting plate and the lamp holder and b) the mounting position assembly consisting of the port, the strip notch and the mounting hole on the box body, and the stability of the assembly structure between the two components.

The mounting hole 1010 is opened to be an open gap, the mounting hole 1010 to be closed and the port 888 are communicated into a whole on the box body 100, and the shape of the mounting hole 1010 and the port 888 corresponds to the shape of the integrated end plate 200, the connecting plate 201 and the lamp holder seat 202, so that the assembly of the lamp box is more convenient. If the mounting holes 1010 are separate from and not integral with the ports, then in such a case, not shown in the drawings, a strip-shaped recessed area (not shown) may preferably be formed in the top wall 1001 of the housing 100 "between the ports 888 and the mounting holes 1010" to accommodate the attachment plate 201, thereby further facilitating the degree of fit with the housing structure during assembly of a) the lamp base and end plate assembly formed by the attachment plate to b) the housing.

With the help of the strip-shaped depressions or the strip-shaped notches in the above and the following embodiments, the box walls with complete appearance and structure can be formed, the box walls with the connecting plates are also enabled to have flat/flat structures, the flat/flat structures are consistent with other parts of the box body, and the mechanical coupling degree and the structural strength between the connecting plates and the box walls are improved to a certain extent. In addition, the hole-shaped structure for mounting the end plate, the lamp holder seat and other parts on the box body such as the port or the mounting hole belongs to a mounting structure matched with a convex and a concave, so that the mechanical coupling degree between the end plate and the lamp holder seat can be obtained, and after the lamp holder seat and the end plate are integrally connected into a combined body by the connecting plate, the structural strength between the combined body and the port and the mounting hole on the box body is further improved.

Optionally, the light box 100' further comprises: the first limiting part and the second limiting part are arranged on the port, extend from the inner side of the end plate 200 to the inside of the port 888 and are relatively fixed with the first limiting part through convex-concave matching, so that the end plate 200 is limited on the port 888.

The second limiting portion further includes a limiting plate 208, the protrusion of the limiting plate 208 forms a first position, the first limiting portion is a second position formed on the plate body at the port by the recess, and the second position is a through hole (not shown in the figure).

In an alternative embodiment, the limiting plate 208 is recessed to form a first position, the first position is a second position 400 formed on the plate body protruding from the port, and the first position is a through hole, as shown in fig. 5.

The second position 400 is located on the lower surface of the partition 1003 and/or the upper surface of the second stopping wall 1006, and the first position spatially corresponds to the second position 400, so as to be clamped and fixed with the second position 400. On the other hand, if the second locking portions are provided at two positions, i.e., the lower surface of the partition 1003 and the upper surface of the second stopper wall 1006, the endplate 200 can be fixed at two positions, i.e., the upper and lower positions, and the whole structure is more stable.

The end section 1007 of the second stopping wall 1006 is bent inward, the emergency lighting lamp box 10X/end plate 200 further includes a first limiting groove 802 extending from the inner side of the end plate 200 to the port 888, the notch faces the top wall, and the first limiting groove 802 is in sliding fit with the end section 1007 of the second stopping wall 1006.

A first notch is formed on the single-side groove wall at the inlet of the first limiting groove, and the first notch is inclined/smoothly transited to the groove.

The end section 1007 of the partition 1003 is bent inwards, and the emergency lighting lamp box further comprises a second limiting groove 803 extending inwards from the inner side of the end plate 200 to the port 888, wherein the groove faces the bottom wall and is in sliding fit with the end section 1007 of the partition 1003. The notches of the second limiting grooves 802 and the first limiting grooves 803 are staggered and opposite.

A second notch is formed on the single-side groove wall at the inlet of the second limiting groove, and the second notch is inclined/smoothly transited to the groove, as shown in fig. 10, the first limiting groove and the second limiting groove are in sliding fit with the notch shape at the inlet, so that the first end section 1007 and the second end section 1007 can be guided to be smoothly inserted into the groove from the side inlet of the groove. Since the end section 1007 is not only directly connected with the box body 100 integrally, but also is limited with the limiting

grooves
