Description

Technical Field

[0001] The utility model relates to the technical field of fire emergency lighting lamps, in particular to a wall-mounted structure for fire emergency lighting. Background Art

[0002] A fire emergency lighting lamp is a fire emergency lamp that provides lighting for personnel evacuation and fire fighting operations. It usually uses an external power supply for power supply and automatically switches to the battery power supply state when the power is cut off.

[0003] Common fire emergency lighting lamps are generally installed at a height of 2.2 meters or above, mostly suspended or wall-mounted above the safety exit (fire safety passage) or above the door frame. When installed wall-mounted, corresponding holes are drilled on the wall according to the position of the hanging buckle slots on the fire emergency lighting lamp, and then expansion screws are installed so that the ends of the screws protrude from the wall surface. Then, the fire emergency lighting lamp can be sleeved on the ends of the screws through the hanging buckle slots.

[0004] However, in the actual operation process, the hole position is prone to deviation when drilling holes in the wall, resulting in the installation distance between the two expansion screws being greater than or less than the distance between the two hanging buckle slots on the fire emergency lighting lamp, so that it cannot be installed. In addition, when the length of the end of the screw protruding from the wall surface is too long, the back of the fire emergency lighting lamp does not fit the wall, and the fire emergency lighting lamp is prone to shaking. Based on this, a wall-mounted structure for fire emergency lighting is provided. Content of the Utility Model

[0005] The purpose of the utility model is to provide a wall-mounted structure for fire emergency lighting in order to solve the problems in the above background.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A wall-mounted structure for fire emergency lighting, including a fire emergency lighting lamp with a lamp box. A trapezoidal groove is formed at the bottom of the back of the lamp box. An inverted trapezoidal protrusion is fixed in the middle of the inner side of the trapezoidal groove. L-shaped buckle connection grooves are formed at the inner edge of the trapezoidal groove and the outer edge of the inverted trapezoidal protrusion.

[0007] The overall trajectory of the L-shaped buckle connection grooves on the trapezoidal groove and the inverted trapezoidal protrusion is in an "M" shape, which is used for clamping operations with two expansion screws with different distances.

[0008] As a further scheme of the utility model: The width of the gap between the top of the trapezoidal groove and the top of the inverted trapezoidal protrusion matches the diameter of the screw rod of the expansion screw, and the distance between the two gaps between the top of the trapezoidal groove and the top of the inverted trapezoidal protrusion is the standard installation distance of the expansion screw.

[0009] As a further solution of the present utility model: receiving grooves are formed on both sides of the back surface of the light box, and an N-shaped elastic sheet is fixedly connected to the inner side of the receiving groove. The N-shaped elastic sheet protrudes outside the receiving groove. Through the extrusion deformation of the N-shaped elastic sheet and the wall surface, pressure is provided for the light box to keep it in a stable and immovable state.

[0010] As a further solution of the present utility model: the vertical height of the folded edge of the N-shaped elastic sheet is less than the vertical height of the receiving groove, and the thickness blocked by the contraction of multiple folded edges of the N-shaped elastic sheet is less than the inner wall depth of the receiving groove.

[0011] As a further solution of the present utility model: the fire emergency lighting lamp further includes a lighting lamp and a power connection wire;

[0012] The lighting lamp is movably connected to the top of the light box through a bracket and is electrically connected to the internal circuit board of the light box through a wire;

[0013] The power connection wire penetrates through the middle of the bottom of the trapezoidal groove from the back surface of the light box to the inside of the light box and is electrically connected to the internal circuit board of the light box.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] By setting the trapezoidal groove and the inverted trapezoidal protrusion, the overall trajectory of the L-shaped buckle connection groove is in an "M" shape, and it can be clamped with two expansion screws with different spacings. In this way, the installation of the fire emergency lighting lamp is more convenient, the overall installation efficiency is faster, and at the same time, through the setting of the N-shaped elastic sheet, when the expansion screw protrudes too long from the wall surface, the light box can also maintain a stable state under the elastic support of the N-shaped elastic sheet.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 3 , in the embodiment of the present utility model, a wall-mounted structure for fire emergency lighting includes a fire emergency lighting lamp 1 composed of a lamp box 101, a lighting lamp 102, and a power connection line 107. The lighting lamp 102 is movably connected to the top of the lamp box 101 through a bracket and is electrically connected to the internal circuit board of the lamp box 101 through a wire;

[0022] A trapezoidal groove 103 is formed at the bottom of the back surface of the lamp box 101. An inverted trapezoidal protrusion 104 is fixed in the middle of the inner side of the trapezoidal groove 103. L-shaped buckle connection grooves 105 are formed at the inner edge of the trapezoidal groove 103 and the outer edge of the inverted trapezoidal protrusion 104;

[0023] The overall trajectory of the L-shaped buckle connection grooves 105 on the trapezoidal groove 103 and the inverted trapezoidal protrusion 104 is in an "M" shape, which is used for engaging with two expansion screws with different spacings;

[0024] The width of the gap between the top of the trapezoidal groove 103 and the top of the inverted trapezoidal protrusion 104 matches the diameter of the screw rod of the expansion screw. The spacing between the two gaps between the top of the trapezoidal groove 103 and the top of the inverted trapezoidal protrusion 104 is the standard installation spacing of the expansion screw;

[0025] The power connection line 107 penetrates through the middle of the bottom of the trapezoidal groove 103 from the back surface of the lamp box 101 to the inside of the lamp box 101 and is electrically connected to the internal circuit board of the lamp box 101.

[0026] In this embodiment: When this fire emergency lighting lamp 1 is wall-mounted, two corresponding holes can be opened on the wall according to the spacing between the two gaps between the top of the trapezoidal groove 103 and the top of the inverted trapezoidal protrusion 104. Then, expansion tubes are installed in the holes and expansion screws are screwed in. The end of the expansion screw protrudes from the wall surface by a certain distance. Then, the lamp box 101 can be sleeved on the expansion screw through the L-shaped buckle connection groove 105, and the edge of the end of the expansion screw is clamped inside the L-shaped buckle connection groove 105, thereby realizing the wall-mounted installation of the lamp box 101;

[0027] During the above operation, if the distance between the two corresponding holes or slots opened on the wall exactly matches the standard distance, the expansion screw is clamped in the two gaps between the top of the trapezoidal groove 103 and the top of the inverted trapezoidal protrusion 104; if the distance between the two corresponding holes or slots opened on the wall is greater than the standard distance, the expansion screw is clamped inside the L-shaped buckle connection groove 105 at the edge of the trapezoidal groove 103; if the distance between the two corresponding holes or slots opened on the wall is less than the standard distance, the expansion screw is clamped inside the L-shaped buckle connection groove 105 at the top edge of the inverted trapezoidal protrusion 104;

[0028] This makes the installation of the fire emergency lighting lamp 1 more convenient and the overall installation efficiency faster.

[0029] Please refer specifically to Figures 1 to 3 , receiving grooves 106 are formed on both sides of the back of the lamp box 101, and N-shaped elastic pieces 2 are fixedly connected to the inner sides of the receiving grooves 106. The N-shaped elastic pieces 2 protrude outside the receiving grooves 106. Through the extrusion deformation of the N-shaped elastic pieces 2 and the wall surface, pressure is provided for the lamp box 101 to keep it in a stable and immovable state;

[0030] The vertical height of the folded edge of the N-shaped elastic piece 2 is less than the vertical height of the receiving groove 106, and the thickness blocked by the contraction of multiple folded edges of the N-shaped elastic piece 2 is less than the inner wall depth of the receiving groove 106.

[0031] In this embodiment: when the lamp box 101 is clamped with the expansion screw, the N-shaped elastic piece 2 contacts the front surface and deforms and contracts under force. Thus, after the lamp box 101 is installed, the lamp box 101 receives a reverse thrust from the N-shaped elastic piece 2. Subsequently, when the expansion screw protrudes too long from the wall surface, the lamp box 101 can still maintain a stable state;

[0032] In addition, the receiving groove 106 can provide a receiving space for the N-shaped elastic piece 2, so that when the protruding length of the expansion screw is just right, the lamp box 101 and the wall surface can be kept in a fitting state.

[0033] The above-mentioned are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
