Description

Technical Field

[0001] This utility model relates to the field of fire emergency lighting technology, specifically a fire emergency lighting structure. Background Technology

[0002] In existing technology, traditional fire emergency lighting fixtures generally include a light box with LED lamp heads. Inside the light box is a control circuit board that controls the on / off status of the light fixture. Traditional fixing methods typically involve mounting holes on the back of the light box, with screws fixed to the wall. The light box is then secured to the wall by snapping the screws into place through the mounting holes on the back of the light box. During use, the light box is usually fixed to a wall high off the ground to increase its illumination range. Therefore, when maintaining, replacing, or installing fire emergency lighting fixtures, maintenance personnel generally need to use a ladder to climb to the location of the fire emergency lighting fixture to disassemble, replace, and install it. Replacement requires prolonged lifting with both hands, which causes arm fatigue and increases the time required for fixture replacement. Furthermore, prolonged time on the ladder poses a certain danger; fatigued arms can lead to loss of grip and even death when descending.

[0003] Utility model CN218863963U discloses an easy-to-install fire emergency lighting fixture, relating to the field of fire emergency technology. It includes a lighting fixture structure and an installation framework. The lighting fixture structure includes a light box, with overlapping blocks fixedly installed on the back side of the light box and connecting pins fixedly installed on the outer side of the light box. The installation framework includes a back plate, with a plug-in structure fixedly installed on the front of the back plate. The plug-in and positioning structures allow for a quick and effective connection between the back plate and the lighting fixture structure. Multiple positioning blocks can be used to connect the back plate to the wall of the passageway via expansion bolts, enabling workers to quickly assemble and disassemble the back plate and the lighting fixture structure. This achieves the goal of easy installation, reduces the time maintenance personnel spend on ladders, avoids arm fatigue caused by prolonged lifting, improves replacement efficiency, and enhances the safety of maintenance personnel.

[0004] However, the above-mentioned existing technologies still have shortcomings in use: the disassembly, replacement and installation of the light box still require working at height, that is, it is necessary to carry a ladder and then use the ladder to climb up to operate, so there is still a problem of poor convenience in disassembly, replacement and installation.

[0005] Therefore, this utility model provides a fire emergency lighting structure. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fire emergency lighting structure to solve the problems mentioned in the background technology. This utility model has the function of installing the emergency light body at a high place without climbing, making the disassembly, replacement and installation of the emergency light body safer, easier and more convenient.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a fire emergency lighting structure, including an emergency lamp body and a mounting base, a positioning shaft is fixedly provided on the front side of the mounting base, a support arm is rotatably connected to the front end of the positioning shaft, one end of the support arm is detachably connected to the bottom of the emergency lamp body, a limit plate is slidably connected to the front side of the mounting base, and a card plate with one end inserted into the limit plate is fixedly connected to one side of the support arm.

[0008] Furthermore, a connecting sleeve is welded to the other end of the support arm and fitted onto the positioning shaft. The connecting sleeve and the positioning shaft are in clearance fit, and a baffle is bolted to one end of the positioning shaft.

[0009] Furthermore, a pad is fixedly connected to the front side of the mounting base near the bottom, and a cushioning rubber pad is adhered to the upper surface of the pad.

[0010] Furthermore, a sliding groove is provided on the front side of the mounting base, a slider that slides in cooperation with the sliding groove is welded to the rear side of the limiting plate, and a handle is welded to the front side of the limiting plate.

[0011] Furthermore, wedge-shaped grooves are provided on both sides of the limiting plate, and the inner inclined surfaces of the wedge-shaped grooves on both sides of the limiting plate form a V-shaped structure with the larger end facing upward. A V-shaped groove adapted to the wedge-shaped groove is provided at one end of the card plate.

[0012] Furthermore, the bottom of the light box of the emergency light body is fixedly connected to a plug shaft, and the other end of the support arm is welded with a support plate. One side of the support plate has a plug hole that is engaged with the plug shaft.

[0013] Furthermore, the insertion shaft is fitted with a resistance-increasing rubber sleeve that is interference-fitted with the insertion hole.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, by setting a mounting base, positioning shaft, support arm, limiting plate and locking plate, the emergency light body is assembled on the ground and the support arm.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: a fire emergency lighting structure, including an emergency lamp body 1 and a mounting base 2. The mounting base 2 has mounting holes near the side. When in use, the mounting base 2 is mounted on the wall with wall nails.

[0023] In this technical solution, a positioning shaft 3 is fixedly installed on the front side of the mounting base 2. A support arm 4 is rotatably connected to the front end of the positioning shaft 3. The support arm 4 is perpendicular to the positioning shaft 3. One end of the support arm 4 is detachably connected to the bottom of the emergency light body 1. After the emergency light body 1 and the support arm 4 are connected, the support arm 4 is rotated to a vertical position and the emergency light body 1 is at the top. At this time, the emergency light body 1 is at a high position. Conversely, the height of the emergency light body 1 can be reduced. This setting eliminates the need to climb to a height to fix and install the emergency light body 1, and makes subsequent maintenance and replacement operations more convenient.

[0024] Furthermore, a limiting plate 5 is slidably connected to the front side of the mounting base 2. Preferably, the front side of the mounting base 2 has a sliding groove 22, and a slider 51 that slides in cooperation with the sliding groove 22 is welded to the rear side of the limiting plate 5. A locking plate 6, with one end inserted into the limiting plate 5, is fixedly connected to one side of the support arm 4. That is, when the support arm 4 is in an upright position, sliding the limiting plate 5 downwards causes it to insert into the locking plate 6, locking the support arm 4 and thus fixing the emergency light body 1 in a fixed position. A handle 52 is welded to the front side of the limiting plate 5, allowing the operator to control the sliding of the limiting plate 5 up and down.

[0025] Furthermore, wedge-shaped grooves 53 are provided on both sides of the limiting plate 5. The inner inclined surfaces of the wedge-shaped grooves 53 on both sides of the limiting plate 5 form a V-shaped structure with the larger end facing upward. One end of the clamping plate 6 is provided with a V-shaped groove 61 that matches the wedge-shaped groove 53. Thus, when the V-shaped groove 61 and the wedge-shaped groove 53 are in contact, the limiting plate 5 and the clamping plate 6 are in a tight clamping state, and there will be no shaking problem, so that the support arm 4 is in a tight fixed position.

[0026] In this embodiment, the other end of the support arm 4 is welded with a connecting sleeve 41 that is sleeved on the positioning shaft 3. The connecting sleeve 41 and the positioning shaft 3 are in clearance fit and rotational fit. One end of the positioning shaft 3 is connected to a baffle 8 by a bolt 7. When the bolt 7 is removed and the baffle 8 is taken off, the connecting sleeve 41 can be directly pulled out from the positioning shaft 3. This arrangement makes it more convenient to connect and install the mounting base 2 with the wall.

[0027] In this embodiment, a pad 21 near the bottom is fixedly connected to the front side of the mounting base 2. A buffer pad 211 is glued to the upper surface of the pad 21. When the support arm 4 swings into a horizontal position, it will contact the buffer pad 211. This arrangement can provide buffer protection for the emergency light body 1.

[0028] In this embodiment, the bottom of the light box 11 of the emergency light body 1 is fixedly connected to a plug shaft 111, and the other end of the support arm 4 is welded to a support plate 42. One side of the support plate 42 is provided with a plug hole 421 that is engaged with the plug shaft 111, thereby realizing the detachable connection between the emergency light body 1 and the support arm 4. In use, the plug shaft 111 can be a screw structure. In order to improve the connection strength between the light box 11 and the support plate 42, a nut can be used.

[0029] Furthermore, a resistance-increasing rubber sleeve 1111 is fitted on the insert shaft 111 and is interference-fitted with the insertion hole 421. This arrangement can improve the stability of the insertion of the insert shaft 111 and the insertion hole 421.

[0030] Working principle: During installation, first install the mounting base 2 at a low position on the wall using wall nails. Then, insert the connecting sleeve 41 at one end of the support arm 4 into the positioning shaft 3, so that the support arm 4 lies on the buffer pad 211. Then, use bolts 7 and baffles 8 to limit the connection sleeve 41. Next, insert the insertion shaft 111 on the light box 11 into the insertion hole 421. Manually lift the support arm 4 to an upright position, and then manually pull down the handle 52. The limiting plate 5 moves down, causing the wedge groove 53 and the V-groove 61 to engage. At this point, the emergency light body 1 is installed. During use, wire clips can be installed on the support arm 4, or holes can be made inside the support arm 4 for wiring.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
