Description

Technical Field

[0001] This application relates to the field of explosion-proof lights, and more particularly to an explosion-proof lighting fixture and its fixing structure. Background Technology

[0002] Explosion-proof lighting fixtures are a type of lighting fixture with explosion-proof properties. They mainly include flameproof explosion-proof lighting fixtures, safety explosion-proof lighting fixtures, and portable explosion-proof lighting fixtures.

[0003] In related technologies, an explosion-proof lamp includes a lamp body with an installation cavity inside the lamp body. A lighting lamp is installed inside the installation cavity, and a transparent protective cover is installed inside the installation cavity. A protective cover is installed at the opening of the installation cavity. The protective cover plays an explosion-proof role and reduces damage to the lamp.

[0004] Regarding the aforementioned technologies, in the existing technology, there is a certain gap between the protective cover and the transparent protective cover. When the explosion-proof light is not in use, if the staff moves the light or moves items past the explosion-proof light, sharp parts of the items may easily pierce the transparent protective cover through the gap, causing damage to the transparent protective cover and affecting the normal use of the explosion-proof light. This needs to be improved urgently. Summary of the Invention

[0005] In order to reduce damage to explosion-proof lighting fixtures from sharp objects and ensure the service life of explosion-proof lights, this application provides an explosion-proof lighting fixture and its fixing structure.

[0006] The explosion-proof lighting fixture and its fixing structure provided in this application adopt the following technical solution:

[0007] An explosion-proof lighting fixture and its fixing structure include a fixed base, a mounting base rotatably connected to the fixed base, locking rods on both sides of the fixed base that engage with the mounting base, a sliding cavity inside the mounting base, a protective net on one side of the opening of the sliding cavity, an adjusting slide block slidably connected inside the sliding cavity, a lamp holder inside the adjusting slide block, a lighting lamp and a transparent protective cover for protecting the lighting lamp on the lamp holder, drive racks on both sides of the adjusting slide block, and a drive gear on the locking rod that meshes with the drive racks. Rotating the mounting base causes the opening of the sliding cavity to face the fixed base, and the adjusting slide block moves away from the protective net. A locking device is provided on the mounting base for locking the adjusting slide block.

[0008] By adopting the above technical solution, during use, rotating the mounting base so that the sliding cavity opening faces the desired lighting position, the adjusting slide moves closer to the protective net under the action of the drive gear and drive rack, thus enabling the lighting fixture to provide better all-round illumination. After the explosion-proof lighting fixture is used, rotating the mounting base so that the sliding cavity opening faces the fixed base, the adjusting slide moves away from the protective net under the action of the drive gear and drive rack, thus protecting the lighting fixture and the transparent protective cover, reducing the possibility of damage to the explosion-proof lighting fixture, improving the safety of the explosion-proof light and ensuring its service life.

[0009] Optionally, the two parallel sidewalls and the two inclined sidewalls form the mounting cavity sidewalls. The two inclined sidewalls are inclined and close to each other in a direction away from the transparent protective cover. The adjusting slide includes two adjusting slides that are hinged to each other. The ends of the two adjusting slides that are far apart from each other abut against the inclined sidewalls. The inner wall of the adjusting slide is provided with a reflective surface.

[0010] By adopting the above technical solution, and by setting the inclined sidewall to cooperate with the adjusting slide, the position of the adjusting slide can be moved more conveniently, improving the ease of use of the adjusting slide. In addition, the use of a reflective surface can reflect the light and enhance the illumination effect of the explosion-proof lamp.

[0011] Optionally, a sliding block is provided on the side of the adjusting slide that is far apart from each other, and limit posts are provided on both sides of the sliding block. The inclined sidewall is provided with a sliding groove that cooperates with the sliding block along the sliding direction of the adjusting slide, and limit sliding grooves are provided on both sides of the sliding groove that cooperate with the limit posts.

[0012] By adopting the above technical solution, the sliding grooves work together to enable the adjusting slide plate to slide more stably, thereby improving the stability of the explosion-proof lighting fixtures.

[0013] Optionally, an adjustment shaft is provided between the two adjustment slides, the adjustment slides are rotatable around the adjustment shaft, the drive rack is fixed on the adjustment shaft, and an adjustment groove is provided on the parallel sidewall to slide and cooperate with the drive rack.

[0014] By adopting the above technical solution, the adjustable slide can slide more smoothly, improving the convenience and stability of using the adjustable slide plate.

[0015] Optionally, both ends of the drive rack are provided with idle plates, the drive gear rotates on the idle plates, and a reset member is provided at the bottom of the sliding cavity. The reset member is used to pull the adjusting slide away from the protective net.

[0016] By adopting the above technical solution, when the adjusting slide block slides to the extreme positions at both ends of the sliding cavity, the drive gear rotates on the idle plate, which makes it more convenient to adjust various angles. In addition, by using a reset component, the drive rack can cooperate more stably with the drive gear, improving the convenience of adjusting the slider position.

[0017] Optionally, the locking device includes a countersunk groove formed in the side wall of the mounting base, a locking rod telescopically disposed in the countersunk groove, a locking block disposed on the locking rod, a locking rack that meshes with the driving rack disposed on the side of the locking block near the driving rack, and a driving compression spring disposed in the countersunk groove for driving the locking rack to mesh with the driving rack.

[0018] By adopting the above technical solution, during use, the driving rack and locking rack are engaged under the action of the driving spring, thereby locking the driving rack. When it is necessary to rotate the mounting base, the locking rack is separated from the driving rack by pressing the locking rod, so that the mounting base can rotate freely, improving the convenience of using explosion-proof lamps.

[0019] A fixing structure for an explosion-proof lighting fixture includes an adjusting base with an adjusting block. The adjusting block has a rotating hole in a vertical direction. Two connecting blocks are located on the side of the fixing base away from the adjusting base, and a rotating shaft is positioned between the two connecting blocks. The rotating shaft is inserted into the rotating hole. A locking groove is formed on the inner wall of the rotating hole, consisting of two opposing first locking grooves and a second locking groove. The first locking groove is located above the second locking groove. The first locking groove is located on the side of the rotating hole away from the adjusting block, and the second locking groove is located on the side of the rotating hole closer to the adjusting block. Both the first and second locking grooves have engaging grooves on their sidewalls away from the rotating hole, which engage with the rotating shaft.

[0020] By adopting the above technical solution, when the explosion-proof lamp needs to be rotated, the explosion-proof lamp is lifted and the rotating shaft is placed in the rotating hole, so that the explosion-proof lamp can rotate more smoothly. After rotating to the specified angle, under the action of the explosion-proof lamp's own weight, the fixing base is deflected downward, so that the rotating shaft is deflected into the locking slot. The locking slot is used in conjunction to lock the rotating shaft. This design can lock the rotation angle of the explosion-proof lamp more conveniently and improve the convenience of using the explosion-proof lamp.

[0021] Optionally, the rotating shaft is composed of a connecting shaft threadedly connected to two connecting blocks. A rotating cavity is provided in the rotating hole, and a rotating ball is rotatably connected in the rotating cavity. Rotating arc grooves that abut against the rotating ball are provided on both sides of the two connecting shafts that are close to each other.

[0022] By adopting the above technical solution, the rotating shaft can rotate more stably, and the gravity on the fixed seat will first act on the connecting shaft and then abut against the rotating ball, so that the fixed seat can rotate more smoothly. In addition, when the explosion-proof lamp is working, the connecting rod is locked in the locking groove, which can greatly reduce the force on the rotating ball and improve the stability of the fixed structure.

[0023] Optionally, a positioning rod is provided at one end of the connecting shaft near the rotating ball, and a positioning groove is provided on the rotating ball to engage with the positioning rod.

[0024] By adopting the above technical solution, the rotating ball and the connecting shaft can be connected more conveniently, improving the stability of using the connecting rod.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. During use, rotate the mounting base so that the sliding cavity opening faces the desired lighting position. Under the action of the drive gear and drive rack, the adjusting slide moves closer to the protective net, allowing the lighting fixture to provide better all-around illumination. After the explosion-proof lighting fixture is finished using, rotate the mounting base so that the sliding cavity opening faces the fixed base. Under the action of the drive gear and drive rack, the adjusting slide moves away from the protective net, thus protecting the lighting fixture and the transparent protective cover, reducing the possibility of damage to the explosion-proof lighting fixture, improving the safety of the explosion-proof light, and ensuring the service life of the explosion-proof light.

[0027] 2. By tilting the sidewalls and adjusting the slide plate, the position of the adjusting slide can be moved more easily, improving the ease of use of the adjusting slide. In addition, the reflective surface can reflect the light, enhancing the illumination effect of the explosion-proof lamp.

[0028] 3. When it is necessary to rotate the explosion-proof lamp, lift the explosion-proof lamp and position the rotating shaft in the rotating hole. This allows the explosion-proof lamp to rotate more smoothly. After rotating to the specified angle, the fixed base will deflect downwards under the weight of the explosion-proof lamp, causing the rotating shaft to deflect into the locking slot. The locking slot is then used to lock the rotating shaft. This design makes it easier to lock the rotation angle of the explosion-proof lamp and improves the convenience of using the explosion-proof lamp. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1 —5 provides further details regarding this application.

[0036] This application discloses an explosion-proof lighting fixture and its fixing structure.

[0037] Reference Figure 1 and Figure 2 A fixing structure for an explosion-proof lighting fixture includes a fixing base 11, the fixing base 11 being U-shaped.

[0038] A mounting base 7 is rotatably connected to the mounting base 11. Locking rods 8, which interlock with the mounting base 7, are fixed on both sides of the mounting base 11. A sliding cavity 6 is formed inside the mounting base 7. A protective net 1, composed of multiple welded steel bars, is installed on one side of the opening of the sliding cavity 6. An adjusting slide 3 is slidably connected inside the sliding cavity 6. A lamp holder 16 is fixed inside the adjusting slide 3. A lighting lamp 17 and a transparent protective cover 5 for protecting the lighting lamp 17 are installed on the lamp holder 16. Drive racks 14 are fixed on both sides of the adjusting slide 3, and the drive racks 14 are arranged along the length of the adjusting slide 3. (Refer to...) Figure 3A drive gear 20 that meshes with the drive rack 14 is fixed on the locking rod 8. Rotate the mounting base 7 so that the opening of the sliding cavity 6 faces the fixed base 11. The adjusting slide 3 moves away from the protective net 1. A locking device for locking the adjusting slide 3 is fixed on the mounting base 7. The adjusting slide 3 can be fixed by the locking device to reduce the movement of the adjusting slide 3.

[0039] With this design, the distance between the lighting lamp 17 and the protective net 1 can be adjusted simultaneously when adjusting the direction of illumination of the lighting lamp 17, thereby better protecting the lighting lamp 17 and the transparent protective cover 5 and improving the safety of using the explosion-proof lamp.

[0040] Reference Figure 2 and Figure 3 Both ends of the drive rack 14 are integrally formed with idler plates 21. The drive gear 20 rotates on the idler plates 21, so that the adjustment slide 3 can stop moving after reaching its limit position, improving the convenience of using the adjustment slide 3. A reset member 50 is fixed at the bottom of the sliding cavity 6. The reset member 50 is a connecting spring. The connecting spring is used to pull the adjustment slide 3 away from the protective net 1, so that the drive gear 20 can cooperate more smoothly with the drive rack 14.

[0041] Reference Figure 2 and Figure 3 The mounting base 7 is in the shape of a boss, and its width gradually increases along the direction close to the fixed base 11. The sidewall of the mounting cavity consists of two parallel sidewalls 2 and two inclined sidewalls 4, which are inclined and close to each other along the direction away from the protective cover. The adjusting slide 3 includes two adjusting slide plates 31 that are hinged to each other. An adjusting shaft 13 is installed between the two adjusting slide plates 31. The adjusting slide plates 31 rotate around the adjusting shaft 13. The ends of the two adjusting slide plates 31 that are far apart from each other abut against the inclined sidewalls 4. The inner wall of the adjusting slide plate 31 is formed with a reflective surface, which reflects the light to ensure the illumination effect of the explosion-proof lamp.

[0042] Reference Figure 2 and Figure 3 One end of the adjustable slide plate 31, which is far from the other end, is integrally formed with a sliding block 18. The sliding block 18 is a rectangular block, and two limit posts are integrally formed on both sides of the sliding block 18. The limit posts are cylindrical. The inclined side wall 4 is provided with a sliding groove 19 that cooperates with the sliding block 18 along the sliding direction of the adjustable slide plate 31. Limiting grooves 191 that cooperate with the limit posts are provided on both sides of the sliding groove 19. This allows the adjustable slide plate 31 to gradually reduce its tilt angle during the retraction process, thus achieving the purpose of storing the lighting lamp 17. The drive rack 14 is fixed on the adjusting shaft 13. An adjusting groove 51 that cooperates with the drive rack 14 is provided on the parallel side wall 2, which allows the adjustable slide plate 31 to slide more smoothly and stably.

[0043] The locking device includes a countersunk groove 24 formed on the side wall of the mounting base 7. A locking rod 23 is telescopically connected in the countersunk groove 24. A locking block 25 is fixed on the locking rod 23. A locking rack that meshes with the driving rack 14 is fixed on the side of the locking block 25 near the driving rack 14. A driving compression spring 22 for driving the locking rack to mesh with the driving rack 14 is fixed in the countersunk groove 24. The position of the adjusting slide 3 can be locked more stably by the locking rack, thereby improving the stability of using the adjusting slide 3.

[0044] Reference Figure 5 A fixing structure for an explosion-proof lighting fixture includes an adjusting base 10, on which an adjusting block 101 is fixed. The adjusting block 101 has a rotating hole 404 in the vertical direction. Two connecting blocks 12 are fixed on the side of a fixing base 11 away from the adjusting base 10. A rotating shaft is fixed between the two connecting blocks 12. The rotating shaft is inserted into the rotating hole 404. A locking groove 40 is formed on the inner wall of the rotating hole 404. The locking groove 40 is composed of two opposing first locking grooves 401 and second locking grooves 402. The first locking groove 401 is located above the second locking groove 402. The first locking groove 401 is formed on the side of the rotating hole 404 away from the adjusting block 101, and the second locking groove 402 is formed on the side of the rotating hole 404 close to the adjusting block 101. The side walls of the first locking groove 401 and the second locking groove 402 away from the rotating hole 404 are both formed with a locking groove 403 that engages with the rotating shaft.

[0045] Reference Figure 5 The rotating shaft consists of connecting shafts 26 threadedly connected to two connecting blocks 12. A rotating cavity 28 is formed within the rotating hole 404, and a rotating ball 27 is rotatably connected within the rotating cavity 28. The rotating cavity 28 restricts the position of the rotating ball 27. Rotating arc grooves 29 are formed on both sides of the two connecting shafts 26 that are close to each other, and they abut against the rotating ball 27. A positioning rod 53 is fixed to one end of the connecting shaft 26 near the rotating ball 27. A positioning groove 52 is formed on the rotating ball 27 that is inserted into the positioning rod 53, thereby enabling the connecting shaft 26 to connect to the rotating ball 27 more stably.

[0046] The implementation principle of this application embodiment is as follows: The adjusting seat 10 is fixed in the installation position. When using the explosion-proof lamp, the concealed seat is rotated to meet the lighting needs of the workers. Simultaneously, under the action of the drive rack 14 and drive gear 20, the adjusting slide 3 is driven to move closer to the protective net 1, allowing the lighting lamp 17 to better meet the lighting effect. Then, according to the needs of the workers, the angle of the fixed seat 11 is rotated, and the connecting rod is engaged in the locking groove 403, thereby enabling the use of the explosion-proof lamp. After using the explosion-proof lamp, the mounting seat 7 is rotated, thereby simultaneously driving the adjusting slide 3 to move away from the protective net 1, thus completing the retraction of the explosion-proof lamp and increasing the distance between the lighting lamp 17 and the protective cover. This better achieves the purpose of protecting the lighting lamp 17 and the transparent protective cover 5, ensuring the service life of the explosion-proof lamp.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
