Detailed implementation manners

[0026] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation manners.

[0027] As Figure 1 、 Figure 2 and Figure 3 shown, an emergency lighting device for construction engineering includes a support plate 1. A right end of the support plate 1 is provided with an adjustment component 2. The adjustment component 2 includes a first protective shell 21. A left end of the first protective shell 21 is fixedly connected to the right end of the support plate 1. A top and a bottom of an inner surface of the first protective shell 21 are rotatably connected by a first rotating shaft 22. An upper part of an outer surface of the first rotating shaft 22 is fixedly connected with a worm gear 23. A lower part of the outer surface of the first rotating shaft 22 is fixedly connected with a first gear 24. A right end of the support plate 1 is rotatably connected with a worm 25. A right end of the worm 25 is fixedly connected with a knob. A bottom of the inner surface of the first protective shell 21 is rotatably connected with a second rotating shaft 26 and the second rotating shaft 26 penetrates through a bottom of the first protective shell 21 and extends to the outside. An upper part of an outer surface of the second rotating shaft 26 is fixedly connected with a second gear 27. A bottom of the second rotating shaft 26 is fixedly connected with a rotating handle 28. A bottom of the rotating handle 28 is rotatably connected with a movable rod 29;

[0028] When it is necessary to swing the lamp body 41 left and right, it is necessary to rotate the knob. During the rotation of the knob, the worm 25 will be driven to rotate. At this time, the worm gear 23 will rotate synchronously, and then drive the first rotating shaft 22 to rotate, thereby driving the first gear 24 to rotate. During the rotation of the first gear 24, the second gear 27 will be driven to rotate. During the rotation of the second gear 27, the rotating handle 28 will be further driven to rotate, causing the movable rod 29 to swing periodically. The whole process can be achieved only by rotating the knob, which is convenient to use.

[0029] As Figure 4 and Figure 6As shown in the figure, two symmetrically distributed support blocks 3 are fixedly connected to the left end of the support plate 1. A searchlight assembly 4 is arranged between the two support blocks 3. The searchlight assembly 4 includes a lamp body 41. The lamp body 41 is rotatably connected between the two support blocks 3. A limit disk 42 is fixedly connected to the front end of the lamp body 41. A number of limit holes are arranged in an annular array at the front end of the limit disk 42. A sliding groove 43 penetrating through the rear end of the support block 3 is arranged at the front end of the support block 3. A sliding column 44 is slidably connected to the inner surface of the sliding groove 43. A second protective shell 45 is fixedly connected to the front end of the support block 3. A first spring 46 is fixedly connected to the front end of the support block 3. A stop block 47 is fixedly connected to the front end of the sliding column 44;

[0030] The lamp body 41 used in this solution is a conventional device in the prior art, which is mainly used for lighting in construction sites. The model of the lamp body 41 is not limited too much in this solution, as long as it meets the above conditions.

[0031] When the lamp body 41 needs to be swung up and down, pull the stop block 47 outwards. At this time, the first spring 46 is in a stretched state, and the sliding column 44 disengages from the limit hole on the surface of the limit disk 42. When the lamp body 41 rotates to a suitable position, just release the stop block 47. At this time, the stop block 47 returns to its original position under the action of the first spring 46. At this time, the sliding column 44 is inserted into the limit hole of the limit disk 42 again for fixation, preventing the lamp body 41 from detaching during the operation of the device.

[0032] As Figure 4 and Figure 5 and Figure 7 As shown in the figure, a rotating shaft 5 is fixedly connected to the bottom of the support plate 1. A lifting assembly 6 is rotatably connected to the bottom of the rotating shaft 5. The lifting assembly 6 includes a sliding rod 61. A fixed block is fixedly connected to the upper part of the outer surface of the sliding rod 61, and the top of the fixed block is rotatably connected to the bottom of the end of the movable rod 29 away from the rotating handle 28. The top of the sliding rod 61 is rotatably connected to the bottom of the rotating shaft 5. A positioning groove 62 is arranged on the left side of the outer surface of the sliding rod 61. A second spring 63 is fixedly connected to the right side of the inner surface of the positioning groove 62. A metal ball 64 is fixedly connected to the left end of the second spring 63;

[0033] When the overall device needs to be lifted or lowered, just pull out the sliding rod 61 from the sleeve 71. During the process of pulling out the sliding rod 61, the second spring 63 is in a compressed state, and the metal ball 64 is located inside the positioning groove 62. When the sliding rod 61 moves a certain distance, the metal ball 64 extends out of the positioning hole 72 under the action of the second spring 63 to fix the position of the sliding rod 61, preventing the sliding rod 61 from detaching during the operation of the device and affecting the lighting effect.

[0034] As Figure 4As shown, a limiting component 7 is slidably connected to the outer surface of the lifting component 6. The limiting component 7 includes a sleeve 71, and the inner cavity of the sleeve 71 is slidably connected to the outer surface of the sliding rod 61. A plurality of uniformly distributed positioning holes 72 are formed in the left side of the outer surface of the sleeve 71, and the size of the positioning holes 72 matches the size of the metal balls 64. The sliding rod 61 can be moved according to the actual situation, so as to correspond to different positioning holes 72, and the height of the device can be adjusted in this way.

[0035] As Figure 2 shown, a base 8 is fixedly connected to the bottom of the limiting component 7, and universal wheels 9 are fixedly connected to the four corners of the bottom of the base 8. The universal wheels 9 used in this solution are conventional devices in the prior art, and their main function is to facilitate the movement of the device. The model selection of the universal wheels 9 is not restricted too much in this solution, as long as the above conditions are met. The installation method of the universal wheels 9 is not described in detail in this solution.

[0036] The working principle of the present utility model is as follows: When it is necessary to swing the lamp body 41 left and right, the knob needs to be rotated. During the rotation of the knob, the worm 25 will be driven to rotate. At this time, the worm gear 23 rotates synchronously, and then drives the first rotating shaft 22 to rotate, thereby driving the first gear 24 to rotate. During the rotation of the first gear 24, the second gear 27 will be driven to rotate. During the rotation of the second gear 27, the rotating handle 28 will be further driven to rotate, so that the movable rod 29 swings periodically, and then the rotating shaft 5 rotates, thereby realizing the left and right rotation of the support plate 1; When it is necessary to swing the lamp body 41 up and down, the stopper 47 is pulled outwards. At this time, the first spring 46 is in a stretched state, and the sliding column 44 disengages from the limiting hole on the surface of the limiting disc 42. When the lamp body 41 rotates to a suitable position, just release the stopper 47. At this time, the stopper 47 returns to its original position under the action of the first spring 46, and at this time, the sliding column 44 is inserted into the limiting hole of the limiting disc 42 again for fixation; When the overall lifting operation of the device is required, just pull out the sliding rod 61 from the sleeve 71, move the sliding rod 61 according to the actual situation to correspond to different positioning holes 72, and adjust the height of the device in this way.

[0037] The above shows and describes the basic principles, main features and advantages of the present utility model.
