Description

Technical Field

[0001] The utility model relates to the technical field of lighting fixtures, in particular to fire emergency lighting equipment. Background Art

[0002] Fire emergency lighting equipment is a lamp that provides lighting for personnel evacuation and firefighting operations. It is usually powered by an external power supply and automatically switches to battery power when the power is off. It is widely used in high-rise buildings, shopping malls, entertainment venues and other crowded places.

[0003] The utility model patent with patent application publication number CN 219082951 U discloses a fire emergency lighting lamp, including a device body and a lamp holder, wherein two lamp holders are arranged in pairs above the device body, and an adjustment component is provided between the lower end of the lamp holder and the device body.

[0004] In the utility model, the lamp holder can be directly driven to swing through the rotating wheel, the first rotating shaft and the connecting block. The staff can adjust according to the actual situation to facilitate the operation of the staff. The spring will push the moving block to make the tooth groove on the stop sleeve mesh with the gear, stop the gear and the first rotating shaft, so that the adjusted lamp holder is fixed, and the driving shaft drives the second rotating shaft to rotate through the meshing worm and worm wheel, so that the second rotating shaft drives the bracket to rotate. When the bracket is rotated, the angle of the lamp holder on the bracket can be adjusted, so that the lighting range of the lamp holder of the fire emergency lighting lamp is wider.

[0005] However, the above device still has some shortcomings in actual use. The most obvious one is that when adjusting the angle of the lamp head, the user needs to pull the buckle first to make the stop sleeve disengage from the gear, and then needs to continuously rotate the first shaft while keeping the buckle continuously pulled. This makes it impossible to conveniently perform the above operation with one hand, which is inconvenient in actual use. In addition, the driving component is located above the device and lacks shielding, so it may be accidentally touched by pedestrians.

[0006] Therefore, it is necessary to invent a fire emergency lighting device to solve the above problems. Utility Model Content

Due to the limitation of the installation position, the shell 11 forms a natural shielding for the first adjustment sleeve 32 and the second adjustment sleeve 41, and pedestrians in a standing state cannot see the first adjustment sleeve 32 and the second adjustment sleeve 41.

[0027] like Figure 3 As shown, the lighting mechanism 2 includes an upper rotating seat 21, a bracket 22, a rotating shaft 23, a connecting block 24 and a lighting fixture 25, wherein the upper rotating seat 21 is rotatably nested on the top of the shell 11 through a bearing, the bracket 22 is fixedly set on the top of the upper rotating seat 21, the rotating shaft 23 is rotatably nested on the inner side of the bracket 22 through a bearing, the connecting block 24 is fixedly sleeved on the outer side of the rotating shaft 23, and the lighting fixture 25 is fixedly set on the top of the connecting block 24.

[0028] like Figure 3 As shown, the hidden rotation adjustment mechanism 3 includes a lower rotating seat 31, a first adjustment sleeve 32, a first clamping block 33, a first connecting rod 34, a clamping plate 35, a first clamping groove 36 and a fixed arm 37, wherein the lower rotating seat 31 is rotatably nested at the bottom of the shell 11 through a bearing, the first adjustment sleeve 32 is slidably penetrated and arranged at the bottom center of the lower rotating seat 31, the first clamping block 33 is fixedly arranged at the top left side of the first adjusting sleeve 32, the first connecting rod 34 is slidably nested in the inner side of the first adjusting sleeve 32 along the vertical direction and is fixedly connected to the upper rotating seat 21, the clamping plate 35 is slidably sleeved on the outer side of the first adjusting sleeve 32, a plurality of first clamping grooves 36 are arranged, and a plurality of the first clamping grooves 36 are evenly opened at the top of the clamping plate 35, and the fixed arm 37 is fixedly arranged on the side of the clamping plate 35 and is fixedly connected to the inner wall of the shell 11.

[0029] By setting the above-mentioned lighting mechanism 2 and hidden rotating adjustment mechanism 3, when it is necessary to rotate the lighting fixture 25, the first adjusting sleeve 32 is pushed upward, so that the first adjusting sleeve 32 drives the first clamping block 33 to move out from the inner side of the first clamping groove 36, and then the first adjusting sleeve 32 is rotated. At this time, the first adjusting sleeve 32 drives the upper rotating seat 21 to rotate through the first connecting rod 34, and the upper rotating seat 21 drives the lighting fixture 25 to rotate through the bracket 22 and the connecting block 24. After the adjustment is completed, the first adjusting sleeve 32 is pulled down, so that the first adjusting sleeve 32 drives the first clamping block 33 to enter the inner side of the adjacent first clamping groove 36 to complete the locking.

[0030] like Figure 3 As shown, the hidden angle adjustment mechanism 4 includes a second adjusting sleeve 41, a second clamping block 42, a second connecting rod 43, a second clamping groove 44 and a bevel gear 45, wherein the second adjusting sleeve 41 is slidably penetrated and arranged on the bottom side of the lower rotating seat 31, the second clamping block 42 is fixedly arranged on the top of the side of the second adjusting sleeve 41, the second connecting rod 43 is slidably nested in the inner side of the second adjusting sleeve 41 along the vertical direction, a plurality of second clamping grooves 44 are provided, and a plurality of second clamping grooves 44 are evenly opened on the top side of the lower rotating seat 31, and two bevel gears 45 are provided, and the two bevel gears 45 are respectively fixedly arranged on the top of the second connecting rod 43 and the end of the rotating shaft 23, and the two bevel gears 45 are meshed with each other.

When the second adjustment sleeve 41 rotates, the rotating shaft 23 is driven to rotate through the second connecting rod 43 and the bevel gear 45, and then the rotating shaft 23 drives the lighting fixture 25 to rotate through the connecting block 24. After the adjustment is completed, the second adjustment sleeve 41 is pulled down, so that the second adjustment sleeve 41 drives the second clamping block 42 to enter the adjacent second clamping groove 44 to complete the locking.

[0032] Working principle of this utility model:

[0033] In actual use, the device is installed at a lower position on the wall by bolts and the mounting plate 13. Due to the limitation of the mounting position, the housing 11 forms a natural shielding for the first adjusting sleeve 32 and the second adjusting sleeve 41, and pedestrians in a standing state cannot see the first adjusting sleeve 32 and the second adjusting sleeve 41.

[0034] When the lighting fixture 25 needs to be rotated, the first adjusting sleeve 32 is pushed upward so that the first adjusting sleeve 32 drives the first clamping block 33 to move out from the inner side of the first clamping groove 36, and then the first adjusting sleeve 32 is rotated.

[0035] When it is necessary to adjust the lighting angle of the lighting fixture 25, the second adjusting sleeve 41 is pushed upward, and the second adjusting sleeve 41 drives the second clamping block 42 to move out from the inner side of the second clamping groove 44, and then the second adjusting sleeve 41 is rotated. When the second adjusting sleeve 41 rotates, the rotating shaft 23 is driven to rotate through the second connecting rod 43 and the bevel gear 45, and then the rotating shaft 23 drives the lighting fixture 25 to rotate through the connecting block 24. After the adjustment is completed, the second adjusting sleeve 41 is pulled down, so that the second adjusting sleeve 41 drives the second clamping block 42 to enter the adjacent second clamping groove 44 to complete the locking.
