So, when assembling the fire control lamps and lanterns, because the existence of drive fixed column 211, the locking position of drive fastener 213 can be close to in the front of drive body 20, makes to increase an chamber 13 and need not to reserve unnecessary space in its both sides for fixed drive body 20, effectively improves space utilization, makes things convenient for the assembly of follow-up other spare parts, reduces the volume of fire control lamps and lanterns simultaneously, makes things convenient for the transportation, carries and the installation etc. of follow-up fire control lamps and lanterns. In the concrete application, the general volume of drive module in the fire control lamps and lanterns is great relatively, weight is heavier, especially to the fire control lamps and lanterns that have the explosion-proof performance that use in the place that has explosion-proof requirement, this kind of fire control lamps and lanterns generally can be to drive module encapsulation processing, further lead to drive module's volume and weight grow, traditional fire control lamps and lanterns are when assembling drive module, for convenient assembling and follow-up dismantlement maintenance's convenient, can reserve out sufficient space around fixed drive module screw, so that supply extracting tool and staff's hand to stretch into, lead to the volume of current fire control lamps and lanterns to be bigger than normal. And the fire control lamps and lanterns in this embodiment, through the setting of the fixed subassembly 21 of drive, when assembling drive module 2, need not to reserve unnecessary space around drive module 2, openly department can assemble the operation being close to drive body 20, can improve space utilization on the one hand, makes things convenient for the dismouting maintenance of follow-up fire control lamps and lanterns, and on the other hand is favorable to assembler's assembly, improves production efficiency.

Simultaneously, because the fire control lamps and lanterns are generally installed in the eminence of wall, when dismantling the maintenance in the later stage, the screwed connection of the fixed drive body of current fire control lamps and lanterns just can see the screw in the bottom surface in increasing an ampere chamber, and maintenance personal need be in higher position department, is unfavorable for subsequent maintenance operation. In the fire-fighting lamp in the embodiment, the driving fastener 213 is connected to the driving fixing column 211, so that the driving fastener 213 can be disassembled and assembled without climbing to the same height as the fire-fighting lamp by a maintenance worker, and the maintenance of the subsequent fire-fighting lamp is facilitated. In addition, for the fire-fighting lamp with explosion-proof requirement, the driving module 2 is directly locked on the shell by using screws in the prior art, so that the thickness of the shell is reduced, the sealing effect of the added safety cavity in the shell is influenced, and the explosion-proof performance of the fire-fighting lamp is further influenced. The existing explosion-proof fire-fighting lamp generally overcomes the problems by increasing the thickness of the shell or shortening the length of the screw, and firstly, the increase of the thickness of the shell can lead to the increase of the whole weight of the fire-fighting lamp, which is not beneficial to the installation reliability of the fire-fighting lamp; for the drive module adopting the encapsulation explosion-proof method, the weight of the drive module is increased, and the shortened screw may cause the reliability of the drive module fixation to be adversely affected. And the drive fastener 213 of this embodiment locks on drive fixed column 211, can not influence casing 1's thickness, is favorable to guaranteeing fire control lamps and lanterns leakproofness and explosion-proof effect, can reduce casing 1's volume simultaneously, effectively reduces the whole weight of fire control lamps and lanterns, improves the reliability of installation.

Referring to fig. 2, as an alternative embodiment of the present embodiment, the driving body 20 has a first side 201 and a second side 202 opposite to each other, and a third side 203 and a fourth side 204 opposite to each other, the first side 201 and the third side 203 are respectively close to different sidewalls of the increased safety cavity 13, and the second side 202 is close to the battery module 3. The driving fixing members 21 are provided in two sets, wherein one set of the driving fixing members 21 may be located between the second side 202 and the battery module 3, and the other set of the driving fixing members 21 may be located between the third side 203 and the sidewall of the increased safety chamber 13. Thus, the driving body 20 can be as close as possible to the side wall of the safety-enhanced cavity 13, so as to reduce the space occupied by the driving body 20, and the driving pressing sheets 212 of the two sets of driving fixing components 21 can be respectively pressed at the diagonal positions of the driving body 20, so that the stability of the driving body 20 can be ensured by the smaller number of the driving fixing components 21.

Specifically, the housing 1 and the increased safety cavity 13 may both be substantially rectangular, the driving body 20 may also be rectangular, and after the fire-fighting lamp is installed, the driving body 20 may be close to a position below the increased safety cavity 13, so that the gravity of the driving body 20 acts on the side wall of the increased safety cavity 13. Of course, in other embodiments, the driving body 20 may be located at other positions of the safety chamber 13 and supported by the driving fixing assemblies 21, and the number and positions of the driving fixing assemblies 21 may be selected according to the size and weight of the driving body 20.

Specifically, the wiring module 4 is used for connection with an external power source and is electrically connected to the driving module 2.

In the specific application, because there is no extra space around the driving module 2, and the sizes of the wiring module 4 and the battery module 3 are generally smaller than those of the driving module 2, in this embodiment, the wiring module 4 and the battery module 3 are arranged side by side and close to the second side 202 of the driving body 20, meanwhile, the wiring module 4 is close to the third side 203 of the driving body 20, the battery module 3 is close to the fourth side 204 of the driving body 20, the cable of the wiring module 4 can be connected with the driving body 20 through the third side 203, and the cable of the battery module 3 can be connected with the driving body 20 through the fourth side 204, so that the length of the cable is reduced as much as possible, the routing in the increased safety cavity 13 is more orderly, and the subsequent maintenance is convenient.

With reference to fig. 2, as an alternative embodiment of the present embodiment, the casing 1 is provided with a wire pressing assembly 112, the wire pressing assembly 112 is located at a side of the casing 1 close to the wiring module 4, and a cable of an external power source can pass through the wire pressing assembly 112 into the increased safety cavity 13 and be connected to the wiring module 4. So, can further reduce the length of inside cable, make things convenient for the installation of fire control lamps and lanterns.

Specifically, line ball subassembly 112 is including setting up in the line ball through-hole of casing 1, connecting in the line ball nut and the sealing member of line ball through-hole, and external power supply's cable can pass the sealing member and get into and increase an ampere chamber 13, and the sealing member can keep increasing an airtight effect in chamber 13 under line ball nut's effect, so, can improve the dustproof and waterproof performance of fire control lamps and lanterns on the one hand, and on the other hand to the place that has the explosion-proof requirement, increases an airtight explosion-proof performance that is favorable to fire control lamps and lanterns in chamber 13.

In the concrete application, the line pressing assembly 112 can be arranged on the two sides of the shell 1 or the top of the shell 1, and when the fire-fighting lamp is installed, an external power supply can be selected to enter the position of the safety increasing cavity 13 according to the specific situation on the site, so that the fire-fighting lamp can adapt to various scenes. Of course, in other embodiments, the crimping assemblies 112 may be replaced with the Glan joints 63.
