The emergency exit light charging and discharging equipment is the battery that supplies power inside the lamp. The battery is charged and discharged to ensure that the emergency exit light can light up and work normally after a power outage.

[0003] Existing emergency exit light charging and discharging equipment and charging and discharging batteries of emergency exit lights are installed with bolts or other auxiliary fixings, and are directly fixed in the housing of the exit light fixture. The battery is then connected to the fixture using a transmission line, thereby realizing the assembly and use of the complete fixture. However, the charging and discharging batteries require regular maintenance to prevent the batteries from being damaged due to long periods of non-use. During manual inspection and maintenance, it is necessary to unscrew the outer bolts one by one to first open the housing cover of the fixture, and then unscrew the bolts that fix the internal battery before the battery can be removed for inspection. Not only is disassembly cumbersome, but reinstallation is also inconvenient, which greatly reduces the work efficiency and convenience of battery inspection and maintenance.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and an emergency exit light charging and discharging device that is easy to maintain is proposed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 2-Figure 4 As shown, an emergency exit light charging and discharging device which is easy to maintain comprises a shell 1, two fixing seats 2 are fixedly provided at the bottom of the inner surface of the shell 1, a charging and discharging battery 3 is provided above the fixing seat 2, two T-blocks 4 are fixedly installed below the surface of the charging and discharging battery 3, T-slots 5 are provided above the surface of the fixing seat 2, a blocking rod 6 is slidably penetrated through the inner front end of the T-slot 5 near the middle side, the front side of the surface of the blocking rod 6 located inside the T-slot 5 is set as an inclined surface, a paddle 7 is fixedly provided above one end of the blocking rod 6 near the middle, and a guiding mechanism 8 is provided below the blocking rod 6.

[0024] By adopting the above technical solution, the front side of the blocking rod 6 is an inclined surface and the rear side is a right-angle surface, so that the T-block 4 can be smoothly inserted into the T-slot 5 and cannot be removed from the T-slot 5;

[0025] When disassembly is required, the paddle 7 is manually pressed to move the blocking rod 6 toward each other for a second time, thereby opening the T-slot 5 and pulling out the T-block 4 to dismantle the charging and discharging battery 3 .

[0026] Furthermore, the guiding mechanism 8 includes a slide groove 801 provided in the middle portion below the inner surface of the shell 1, a guide rod 802 is fixedly installed on the inner surface of the slide groove 801, and the guiding mechanism 8 also includes a guide block 803 slidably arranged on the surface of the guide rod 802, a spring 804 is sleeved on the middle portion of the opposite side of the surface of the guide block 803 and fixedly installed on the outer side of the guide rod 802, the upper end of the guide block 803 is fixedly connected to the blocking rod 6, and the surface of the guide block 803 slides in contact with the inner surface of the slide groove 801 on all sides.

[0027] By adopting the above technical solution, the slide groove 801 and the guide rod 802 limit the guide block 803 and the blocking rod 6, so that the blocking rod 6 is more stable when being pushed and moved, and avoids deviation and jamming;

[0028] The spring 804 utilizes its own elastic force to push the blocking rod 6 to reset through the guide block 803, and re-blocks the T-slot 5 insertion port to block the inserted T-block 4.

[0029] like Figure 1-Figure 2 As shown, ventilation mesh grooves 9 are evenly distributed on the outer surface of the housing 1 , and air inlet fans 10 are installed on both left and right sides of the outer surface of the housing 1 .

[0030] By adopting the above technical solution, the breathable mesh slot 9 performs passive heat dissipation, and the hot air moves upward according to the physical characteristics and can be automatically dissipated into the air;

[0031] The air inlet fan 10 blows air into the housing 1 to increase the air circulation rate, thereby making the heat dissipation capacity stronger when the battery 3 is charged and discharged.

[0032] Furthermore, a transparent cover plate 11 is rotatably provided on the upper front side of the inner surface of the housing 1 via a rotating shaft, and an indicator light is embedded in the inner wall of the transparent cover plate 11, and the indicator light is connected to the charging and discharging battery 3 via a power line.

[0033] By adopting the above technical solution, the transparent cover plate 11 facilitates manual observation of the charging and discharging status of the battery 3 inside the housing 1;

[0034] The indicator light is connected to the charging and discharging battery 3 so that the surface of the transparent cover plate 11 can present an emergency indication mark.

[0035] Furthermore, a connecting foot 12 is fixedly installed at the lower front side of the surface of the transparent cover plate 11 , and screw holes 13 are provided at corresponding positions where the surface of the connecting foot 12 and the housing 1 are in contact.

[0036] By adopting the above technical solution, the transparent cover plate 11 can be fixed to the screw holes 13 on the outer shell 1 by using the screw holes 13 on the connecting pins 12 , so that the outer shell 1 is closed to protect the charging and discharging battery 3 .

[0037] Working principle: When using the emergency exit light charging and discharging device which is easy to maintain, first, when installing the charging and discharging battery 3, first remove the bolts between the shell 1 and the connecting foot 12, turn the transparent cover 11 upward, open the front side of the shell 1, and then align the T-block 4 with the T-slot 5 and insert it, use the inclined surface to push the blocking rod 6 to move toward the middle and squeeze the spring 804. When the T-block 4 is inserted into the end of the T-slot 5, the spring 804 uses its own elastic force to push the blocking rod 6 to reset through the guide block 803, and re-blocks the T-slot 5 socket. At this time, the T-block 4 cannot use the right-angled surface on the rear side of the blocking rod 6 to push the blocking rod 6 to move, so that the charging and discharging battery 3 can be installed. Then, after the internal circuit is connected to the charging and discharging battery 3, close the transparent cover 1. 1 can be used. After a certain period of use, manual maintenance and testing are performed. The transparent cover 11 is opened for the second time, and the paddle 7 is manually pinched to make the blocking rod 6 move toward each other for the second time, so that the T-slot 5 can be opened, and the T-block 4 is pulled out to remove the charging and discharging battery 3, and the charging and discharging battery 3 can be inspected, maintained or replaced. When the external light source fails and the emergency exit light starts to work, the charging and discharging battery 3 supplies power to the indicator light and the intake fan 10, and the indicator light lights up to indicate the exit direction. The intake fan 10 will start synchronously to blow fresh air from the outside into the housing 1. The fresh air carries the hot air flow generated by the charging and discharging battery 3 during work and is discharged through the breathable mesh slot 9 to dissipate the heat of the charging and discharging battery 3. This is the working principle of the emergency exit light charging and discharging device that is easy to maintain.
