Emergency light locking structure Technical Field
[0001] This utility model relates to the field of lighting device technology, specifically to an emergency lamp locking structure. Background Technology
[0002] Lighting activated when normal lighting fails is called emergency lighting. Certain regions require a certain number of emergency lights in certain locations. In emergencies such as fires, earthquakes, or other unforeseen events, emergency lighting provides necessary illumination for evacuation and ensures personnel safety. Some existing emergency lighting solutions utilize pre-installed lamp holders within the fixtures as fixed or power input terminals to house the lamp tubes, along with built-in or external emergency batteries and drivers to meet emergency lighting needs.
[0003] Emergency lighting needs to meet certain specific testing requirements, such as the UL924 emergency light test, which stipulates that the emergency light should not be easily removed without tools. However, meeting these test requirements makes installation cumbersome, inefficient, and increases both product price and labor costs. Summary of the Invention
[0004] To overcome the shortcomings of the existing technology, this utility model proposes an emergency light locking structure that can meet the locking requirements of the emergency light while being easy and quick to install.
[0005] To achieve the above objectives, the emergency lamp locking structure of this utility model includes a lamp tube, with locking mechanisms at both ends of the lamp tube. The locking mechanisms are used to lock the lamp tube in a lamp holder provided on the lamp fixture outside the lamp tube. The locking mechanism includes a fixing part and a rotating part. The fixing part is fixedly installed at the end of the lamp tube, and the rotating part is disposed between the fixing part and the end of the lamp tube.

[0020] The technical solution of this utility model will be more clearly and completely explained below with reference to the accompanying drawings and through the description of the preferred embodiments of this utility model.
[0021] As shown in Figure 1, the emergency lamp locking structure of the preferred embodiment of this utility model includes a lamp tube 2, with locking mechanisms at both ends of the lamp tube 2. The locking mechanisms are used to lock the lamp tube 2 onto the lamp holders 1 on both sides. The lamp holders 1 are installed in the mounting holes of existing lamps, and can adopt the installation method of the original lamp holders G13 or T8, which will not be described in detail here.
[0022] As shown in Figures 3 and 5, the locking mechanism includes a fixing part 3 and a rotating part. The fixing part 3 is fixedly installed at the end of the lamp tube 2 and has an annular structure. A through hole with a circular cross-section is opened in the center of the fixing part 3. Three buckles 32 are provided on the side of the fixing part 3 near the lamp tube 2, and three fixing grooves 24 that cooperate with the buckles 32 are provided on the side of the lamp tube 2 near the fixing part 3. By fastening the buckles 32 into the fixing grooves 24, the fixing part 3 is fixed to the lamp tube 2.
[0023] As shown in Figures 3 and 5, the rotating part includes a cylindrical rotating disk 41, which is housed in a circular through hole at the center of the fixed part 3 and can rotate along its own axis. A positioning disk 43 is provided at one end of the rotating disk 41 near the lamp tube 2. The diameter of the positioning disk 43 is smaller than the diameter of the rotating disk 41. A limiting disk 44 is provided between the positioning disk 43 and the rotating disk 41. The diameter of the limiting disk 44 is larger than the diameter of the rotating disk 41. A through hole adapted to the positioning disk 43 is provided at the end of the lamp tube 2. A receiving groove 33 adapted to the limiting disk 44 is provided on the side of the fixed part 3 facing the lamp tube 2.
[0024] As shown in Figures 3 and 5, a toggle lever 42 is provided on the rotating disk 41. The toggle lever 42 is arranged on the circumference of the rotating disk 41. A limiting groove 31 is provided on the side of the fixing part 3 near the lamp tube 2. The limiting groove 31 extends along the circumference of the fixing part 3 and has an arc of 90°. The toggle lever 42 is restricted to rotate in the limiting groove 31.
[0025] As shown in Figures 3 and 5, a locking hole 22 is provided at the end of the lamp tube 2, extending circumferentially along the lamp tube 2. A locking element that cooperates with the lever 42 is provided at the end of the lamp tube 2. The locking element includes a locking block 23 disposed in the locking hole 22. One end of the locking block 23 is connected to the inner wall of the locking hole 22, and the other end of the locking block 23 is movable. The surface of the locking block 23 protrudes from the end surface of the lamp tube 2, forming an inclined surface that gradually rises from its fixed end to its movable end. The locking block 23 has a certain degree of elasticity, tending to retain the protrusion.
[0026] As shown in Figures 3 and 5, the lamp holder 1 has a circular blind hole on the side near the fixing part 3. A rotating pin 11 is provided in the blind hole, and a through groove 12 passing through its diameter is provided on the rotating pin 11. A guide groove 13 is provided on the top of the lamp holder 1, and the guide groove 13 can communicate with the through groove 12. This structure is actually the standard structure of G13 or T8 lamp holder 1, and existing G13 or T8 lamp holder 1 can be directly used. The fixing part 3 has a positioning block 34 that cooperates with the guide groove 13 on the side near the lamp holder 1.
[0027] As shown in Figures 3 and 5, the lamp holder 1 has an electrode plate that is electrically connected to an external power supply. The electrode plate is located at the bottom of the blind hole, and the lamp holder 1 is electrically connected to the external power supply via a wire. Two electrode posts 21 are provided on the side of the rotating disk 41 near the lamp holder 1, and the line connecting the two electrode posts 21 is collinear with the diameter of the end face of the rotating disk 41. When the actuating lever 42 is located at the end of the limiting groove 31 away from the locking block 23, the two electrode posts 21 and the positioning block 34 are collinear. When the actuating lever 42 rotates to the position of the locking block 23 and is locked, the two electrode posts 21 and the positioning block 34 are not collinear. The electrode posts 21 can contact the electrode plate, and the electrode posts 21 supply power to the light-emitting components in the lamp tube 2 via a wire connected to the rear, which can be an LED lamp group or a fluorescent lamp, etc.
[0028] Specific implementation process: Before installing the lamp tube 2 onto the lamp holder 1, the fixing part 3 and the rotating part are already installed at the end of the lamp tube 2. The actuating rod 42 is positioned at the higher end of the limiting groove 31 away from the locking block 23. The two electrode posts 21 are collinear with the positioning block 34. The rotating pin block 11 in the lamp holder 1 rotates until the guide groove 13 and the through groove 12 are connected and collinear. At this time, the lamp tube 2 is inserted into the lamp holder 1 vertically. The two electrode posts 21 and the positioning block 34 enter the through groove 12 along the guide groove 13 in sequence. Then, the actuating rod 42 is rotated until it presses past the most protruding part of the locking block 23. The locking block 23 returns to its original shape under elasticity. The actuating rod 42 is locked by the protruding part of the locking block 23, and the actuating rod 42 can no longer rotate, thus achieving locking. At this time, the two electrode posts 21 also rotate with the rotating disk 41, and rotate together with the rotating pin block 11. Eventually, the guide groove 13 and the through groove 12 are misaligned, and the electrode posts 21 contact the electrode plate at the bottom of the blind hole to realize power supply. This also prevents the lamp tube 2 from detaching from the lamp holder 1, and finally achieves the purpose of locking the lamp tube 2 on the lamp holder 1 so that it cannot be disassembled.
[0029] The above-described specific embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Various modifications, substitutions, and improvements made by those skilled in the art to the technical solutions of the present invention based on the provided description and drawings, without departing from the design concept and spirit of the present invention, should all fall within the scope of protection of the present invention. The scope of protection of the present invention is determined by the claims.
