[0004] Existing emergency lighting cannot be adjusted at multiple angles. When used in dangerous situations, the lighting range of the emergency lighting is too small, thereby affecting the lighting escape effect. Utility Model Content

[0005] The utility model provides an emergency lighting lamp which can be adjusted at multiple angles, which solves the problem that the existing emergency lighting lamps cannot be adjusted at multiple angles, and when used in dangerous situations, the lighting range of the emergency lighting lamps is too small, thus affecting the lighting escape effect.

[0006] To achieve the above objectives, the utility model provides the following technical solutions: an emergency lighting lamp that can be adjusted at multiple angles, comprising a box body, wherein the top surface of the box body is upwardly and symmetrically provided with two upright posts, each of the upright posts is fixed with a connecting post forward, the front ends of the two connecting posts are commonly connected to a fixing plate, the fixing plate is provided with two groups of fixing blocks, each group of the fixing blocks contains four blocks and are arranged at the midpoints of the four sides of a square, each group of the fixing blocks is rotatably connected to an angle adjustment frame, the angle adjustment frame comprises a vertically distributed double arc rod 1, a double arc rod 2 that is cocentric with the double arc rod but is distributed perpendicular to each other, An end block is fixed at each end of the double arc rod 1 and the double arc rod 2, the double arc rod 2 is located at the periphery of the double arc rod 1, each of the end blocks is rotatably connected to each fixed block, an axle is fixedly connected between the end blocks located at one end close to each other on the two angle adjustment frames, the end block located at one end of the axle is connected to the output end of motor 1, one of the two end blocks located at the lower end is connected to the output end of motor 2 and the other is connected to the output end of motor 3, each group of the double arc rod 1 and the double arc rod 2 is slidably connected to a sliding fixture at the intersection, and each of the sliding fixtures respectively fixes a lamp forward.

[0007] The beneficial effects of the utility model are as follows: the double arc rod 2 is driven by motor 1 to rotate along a vertical half circle. During the process, the double arc rod 2 pushes two groups of sliding pieces and the lamps to slide on the vertically distributed double arc rod 1, thereby synchronously changing the angles of the two lamps on the vertical plane, and driving motor 2 and motor 3 respectively. The double arc rod 1 can be controlled to rotate along a horizontal half circle respectively. During the process, the double arc rod 1 pushes the sliding piece and the lamp to slide on the transversely distributed double arc rod 2, thereby changing the angle of one lamp on the horizontal plane respectively through motor 2 and motor 3. When the two lamps are controlled to rotate in the same direction, the lighting angle can be adjusted. When the two lamps are controlled to rotate in different directions, the lighting area can be increased. Through the above-mentioned arrangement, the lighting angle can be changed in multiple directions and the lighting area can be changed by changing the angle. The lighting range is large, providing a favorable lighting environment for escape.

[0008] In order to effectively connect the angle adjustment frame and the headlight through the sliding piece, the headlight can slide on the angle adjustment frame to achieve angle change;

[0009] As a further improvement of the above technical solution: each of the sliding parts contains four short sliding tubes, each of the short sliding tubes is slidably connected to the outer side walls of double arc rod one and double arc rod two, the short sliding tube located on the double arc rod two is fixed with a fixing plate forward, the short sliding tube located on the double arc rod one is fixed with an extension strip forward and is indirectly connected to the fixing plate through the extension strip, and the fixing plate is connected to the back of the lamp.

[0010] The beneficial effects of this improvement are as follows: the short sliding tube is directly fixed to the fixing plate or is indirectly fixed to the fixing plate through an extension strip to form a whole, and then the fixing plate and the headlight are connected to achieve fixation between the sliding fixture and the headlight, and the sliding fixture can then slide on the double arc rod one and the double arc rod two through the short sliding tube, thereby achieving sliding of the headlight on the angle adjustment frame, and thus achieving angle change.

[0011] In order to make the connection between the sliding parts and the lighting more stable and conducive to the production process;

[0012] As a further improvement of the above technical solution: the outer diameter of each group of the fixing plates is much larger than the circumscribed circle diameter of the four short sliding tubes connected thereto, and a number of screws are evenly threadedly connected on the fixing plates between the outer wall and the short sliding tubes, and the screws are threadedly connected to the lights.

[0013] The beneficial effects of this improvement are as follows: the short sliding tube is smaller than the headlight. If the short sliding tube is directly fixed to the headlight, it needs to be produced separately and then integrated. By providing a fixing plate with a volume similar to that of the short sliding tube, the short sliding tube, the extension strip and the fixing plate can be directly produced as an integrated whole, and then the sliding piece can be fixed to the headlight by installation, which is more conducive to the production process. Moreover, the installation area formed by connecting the fixing plate and the headlight with screws is much larger than the projection area of ​​the short sliding tube on the headlight. The larger installation area is conducive to a more stable connection.

[0019] The beneficial effects of this improvement are as follows: the electronic components are placed in the box, and the wires are extended to pass through the columns, the connecting columns, and the fixed plate, and then directly pass through the cross gap between the double arc rod 1 and the double arc rod 2, and then pass through the central through hole and then connect to the electronic components inside the lamp. There will be no impact during the rotation of the lamp, and the area where the wires are exposed to the outside is wrapped with a hose, which will not cause wear.

[0025] The beneficial effect of this improvement is that the lower hanging bar and the upper hanging bar are connected in series through the L rod, so that the box and the mounting frame will not be offset, and are fixed more tightly and will not fall off. The support plate set at the bottom can add bottom support force to the box to avoid shaking of the device and ensure stability after installation.

[0026] In order to ensure easy installation, it is also easy to quickly remove the device for later inspection and maintenance;

[0027] As a further improvement of the above technical solution: a push block is slidably connected to the left and right side walls of the box body, and the push block is connected to one end of the L rod. The other end of the L rod extends outward from the inside of the box body and passes through the upper hanging bar and the lower hanging bar.

[0028] The beneficial effect of this improvement is: during installation, after the vertical board has been installed on the wall, after the upper hanging bar is hung on the lower hanging bar, the push block is pushed backward to move the L rod backward, and the L rod connects the upper hanging bar and the lower hanging bar in series, and the installation is completed.
