[0036] 2. The safety explosion-proof LED lamp described in the present invention has a protective rod that rotates on the protective shell through a damping shaft. Therefore, when the protective rod rotates, the friction force of the damping shaft is greater than the gravity of the lamp body itself. Therefore, under the action of the friction force of the damping shaft, the protective rod will not rotate, so that the tilting rod can maintain the rotated state, and the lamp body can maintain the state after moving up in the protective shell. Therefore, it can be avoided that when an object passes through the protective shell, it will hit the lampshade again and cause damage.

[0037] 3. The safety explosion-proof LED lamp described in the present invention has a smaller illumination range of the lamp body when the lamp body moves up to the inside of the protective shell.

At the same time, when the lamp body moves up to the protective shell, the illumination range of the lamp body becomes smaller. In order to restore the illumination range of the lamp body, it is necessary to manually rotate the protective rod and rotate the protective rod to the initial position. After the protective rod is rotated to the initial position, the lamp body will move down to the initial state under its own weight. In the process of the worker rotating the protective rod, the worker can check the lampshade to avoid damage to the lampshade without being discovered, which poses certain safety hazards.

DETAILED DESCRIPTION

[0051] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0052] Embodiment 1: Figures 1 to 11 As shown, a safe explosion-proof LED lamp according to the present invention comprises a lamp body 1; the lamp body 1 comprises a lamp housing 11, and the cross section of the lamp housing 11 is a convex shape; a circuit board is installed in the lamp housing 11; a power line 12 is installed on the top of the circuit board, and the power line 12 passes through the top of the lamp housing 11; a lamp panel is installed on the bottom of the circuit board; a lampshade 13 is provided under the lamp panel; an annular end cover 14 is provided under the lampshade 13, and the annular end cover 14 fixes the lampshade 13 to the lamp housing 11 through a hexagon socket bolt;

[0053] A cover body 2 is installed on the top of the lamp housing 11, and a power line 12 passes through the lamp housing 11; a protective shell 3 is rotatably connected to the outer surface of the lamp housing 11 below the cover body 2, and the cross section of the protective shell 3 is a convex shape; the lamp housing 11 can slide up and down in the protective shell 3;

[0054] A slip ring 31 is fixedly connected to the outer ring surface of the protective shell 3 below the cover body 2; a swivel 32 is rotatably connected to the outer ring surface of the protective shell 3; an annular groove 33 is opened on the inner ring surface of the swivel 32, and the slip ring 31 slides in the annular groove 33;

[0055] The top of the rotating ring 32 is fixedly connected with a protective cover 4, and the cross section of the protective cover 4 is n-shaped; the top of the protective cover 4 is installed with a mounting assembly;

[0056] The top of the cover body 2 is located in the circumferential direction of the cover body 2 and is provided with evenly arranged first through holes 21; the top of the inner cavity of the protective cover 4 is fixedly connected with two limit rods 41, and the two limit rods 41 are inserted into two of the first through holes 21;

[0057] The outer surface of the protective shell 3 is provided with uniformly arranged protective components, and the protective components are used to protect the LED lamps;

[0058] In this embodiment, the bottom of the protective shell 3 is provided with evenly arranged notches 34;

[0059] The plurality of protection components include a tilting rod 35; a mounting block 36 is fixedly connected to the top of the tilting rod 35, and the mounting block 36 is rotated in the notch 34 through a rotating shaft;

[0060] The side of the tilting rod 35 close to the lampshade 13 is a straight rod and extends to the bottom of the annular end cover 14; the side of the tilting rod 35 away from the lampshade 13 is an inclined rod and tilts downward;

[0061] Each of the notches 34 is located on the protective shell 3 and is rotatably connected to a protective rod 39 via a damping shaft, and the protective rod 39 is initially in contact with the downwardly inclined side of the tilting rod 35; and an elastic band 391 is fixedly connected between two adjacent protective rods 39;

[0062] In this embodiment, a slot is provided on one end surface of the tilting rod 35 facing the lampshade 13;

[0063] The slots are each inserted with an insert shaft 37; the insert shaft 37 is fixedly connected to a side of the lampshade 13 with an arc layer 38, and the arc layer 38 fits the lampshade 13; the insert shaft 37 and the arc layer 38 are both made of insulating rubber;

[0064] Specifically, when the LED lamp is used, the LED lamp is first installed at a desired position using the installation assembly, and then the power cord 12 of the LED lamp is connected to a power source, and then the LED lamp can be put into use. When in use, the light emitted by the lamp panel can be illuminated through the lampshade 13;

[0065] More specifically, when the LED lamp is in use, since the lamp body 1 is located in the protective shell 3, and the outer ring of the protective shell 3 is rotatably installed with uniformly arranged protective rods 39, if a worker accidentally hits the lamp body 1 when carrying something, the protective rod 39 can block the object that hits, thereby avoiding direct impact on the lamp body 1, thereby damaging the lampshade 13 on the lamp body 1. At the same time, due to the existence of the protective shell 3, when an object passes through the protective rods 39 and hits the lamp body 1, due to the existence of the protective shell 3, the protective shell 3 can block the lamp body 1, thereby bearing the impact of the impact on the lamp body 1, thereby further protecting the lamp body 1, avoiding the lampshade 13 from being damaged, thereby losing the explosion-proof effect of the explosion-proof lamp itself, and at the same time, due to the existence of the protective shell 3 and the protective cover 4, it can prevent external dust or other impurities from directly adhering to the lamp body 1, thereby avoiding direct impact on the lamp body 1;

[0066] Furthermore, when an external object hits the lamp body 1, if the trajectory of the external object is facing the external protective rod 39, it will hit the protective rod 39. When the protective rod 39 is hit, the protective rod 39 will rotate downward due to the external force. The downward rotating protective rod 39 will squeeze the tilting rod 35 located below the protective rod 39, thereby pushing the mounting block 36 on the tilting rod 35 to rotate around the rotating shaft. At the same time, the tilting rod 35 located below the annular end cover 14 will tilt upward. The tilting rod 35 that tilts upward will push the annular end cover 14 to move upward. At the same time, the annular end cover 14 will drive the lampshade 13 and the lamp housing 11 to move upward in the protective shell 3. At the same time, the protective shell 3 will drive the cover body 2 to move upward along the limit rod 41, so that the lamp body 1 can be pushed into the protective shell 3.

[0067] Since the protection rod 39 is rotated on the protection shell 3 through the damping shaft, when the protection rod 39 is rotated, the friction force of the damping shaft is greater than the gravity of the lamp body 1 itself. Therefore, under the action of the friction force of the damping shaft, the protection rod 39 will not rotate, so that the tilting rod 35 can maintain the rotated state, and the lamp body 1 can maintain the state after moving up in the protection shell 3. Therefore, it can be avoided that when an object passes through the protection shell 3, it will hit the lampshade 13 again and cause damage. At the same time, when the lamp body 1 moves up to the inside of the protection shell 3, the irradiation range of the lamp body 1 will become smaller. When the irradiation range of the lamp body 1 becomes smaller, it will attract the attention of the workers. At the same time, when the workers When a person carries an object and hits the protective rod 39, it will also attract the attention of the worker. Then the worker can check the lamp body 1 to see if there is any damage. At the same time, when the lamp body 1 moves up into the protective shell 3, the irradiation range of the lamp body 1 becomes smaller. In order to restore the irradiation range of the lamp body 1, it is necessary to manually rotate the protective rod 39 and rotate the protective rod 39 to the initial position. When the protective rod 39 is rotated to the initial position, the lamp body 1 will move down to the initial state under its own weight. In the process of the worker rotating the protective rod 39, the worker can check the lampshade 13, thereby avoiding the lampshade 13 being damaged but not discovered, which may cause certain safety hazards.

[0068] Furthermore, during the rotation of the tilting rod 35, the plug shaft 37 and the arc layer 38 will also be driven to rotate. Since the plug shaft 37 and the arc layer 38 are made of insulating rubber material, the arc layer 38 rotating with the tilting rod 35 is always in contact with the lampshade 13. If an external object passes by the side of the lamp body 1 and hits the protective rod 39, the protective rod 39 will push the protective shell 3 to rotate around the lamp body 1. At the same time, the protective shell 3 will drive the slip ring 31 to rotate in the annular groove 33. When the protective shell 3 rotates, it will drive The tilting rod 35 rotates, and at the same time, the tilting rod 35 drives the plug shaft 37 and the arc layer 38 to rotate. During the rotation of the arc layer 38, it can rotate along the lampshade 13. The rotating arc layer 38 will block the light source, thereby forming a rotating shadow. When the rotating shadow is formed, it will attract the attention of the workers, so that they can check it. At the same time, during the rotation of the arc layer 38 along the lampshade 13, the surface of the lampshade 13 can be wiped, thereby reducing dust on the lampshade 13, preventing the dust on the lampshade 13 from blocking the light, and reducing the brightness of the lamp body 1;

[0069] Since an elastic band 391 is provided between two adjacent protective rods 39, if the trajectory of the movement of an external object passes through between the two protective rods 39 and faces the protective shell 3, the elastic band 391 can cushion the passing object, thereby reducing the force of the object's collision and avoiding direct collision on the protective shell 3. When the elastic band 391 cushions the object, the elastic band 391 will drive the protective rod 39 to rotate, and the rotating protective rod 39 will push the lamp body 1 upward through the tilting rod 35, thereby protecting the lamp body 1.

[0070] Embodiment 2: The mounting assembly includes a sphere 42; the top of the protective cover 4 is fixedly connected with the sphere 42, and the middle of the sphere 42 is hollow, and the power line 12 passes through the middle of the sphere 42;

[0071] An arc ring 43 is spherically connected to the outer ring surface of the sphere 42; a rubber layer 44 is fixedly connected to the bottom of the arc ring 43, and the bottom of the rubber layer 44 is fixedly connected to the protective cover 4, and the rubber layer 44 is cylindrical;

[0072] The outer surface of the arc ring 43 is fixedly connected with a mounting tube 45, and the upper half of the sphere 42 is located in the mounting tube 45; the power line 12 passes through the top of the mounting tube 45;

[0073] The two sides of the installation tube 45 are fixedly connected with installation plates 46, and the installation plates 46 are used to install the LED lamp;

[0074] Specifically, when the protective rod 39 or the protective shell 3 is hit, the protective shell 3 or the protective rod 39 will tilt and swing under the action of external force, and the protective cover 4 will drive the ball 42 to rotate in the arc ring 43. When the protective shell 3 is swung by the external force, the impact force on the protective shell 3 or the protective rod 39 itself can be reduced, thereby preventing the protective shell 3 from being fixed and bearing the impact force brought by the object when the object hits the protective shell 3 or the protective rod 39;

[0075] Since the rubber layer 44 fixedly connected to the bottom of the arc ring 43 is fixedly connected to the protective cover 4, when the protective cover 4 rotates, the protective cover 4 will drive the rubber layer 44 to deform, thereby preventing the rubber layer 44 from affecting the rotation of the protective cover 4. At the same time, the rubber layer 44 can block external dust or other impurities to prevent dust from adhering to the sphere 42. At the same time, the upper part of the sphere 42 is located in the installation tube 45, so it can also block external dust or other impurities to prevent dust from adhering to the sphere 42.

[0076] Embodiment 3: The top of the lamp housing 11 is provided with a thread on the outer surface of the lamp housing 11;

[0077] The inner surface of the cover body 2 is also provided with threads, and the cover body 2 is mounted on the lamp housing 11 through the threads;

[0078] In this embodiment, a truncated cone groove 22 is provided in the middle of the cover body 2;

[0079] A conical block 23 is slidably connected in the truncated cone groove 22, and the maximum diameter of the conical block 23 is greater than the maximum diameter of the truncated cone groove 22; the conical block 23 is made of insulating rubber;

[0080] In this embodiment, a retaining ring 24 is provided on the outer surface of the lamp housing 11 below the cover body 2, and the retaining ring 24 is located between the cover body 2 and the protective housing 3;

[0081] The retaining ring 24 is provided with uniformly arranged second through holes 25, and the number of the second through holes 25 is the same as the number of the first through holes 21, and they correspond one to one in the initial state; the two limiting rods 41 pass through the first through holes 21 and extend into two of the second through holes 25;

[0082] The outer surface of the retaining ring 24 is provided with uniformly arranged first countersunk holes 26; the outer surface of the lamp housing 11 is provided with uniformly arranged first thread grooves 27, and the first thread grooves 27 correspond to the first countersunk holes 26 one by one;

[0083] The first countersunk holes 26 are each provided with a hexagon socket bolt, and the hexagon socket bolt is engaged in the first thread groove 27, so as to fix the retaining ring 24 on the lamp housing 11;

[0084] Specifically, since the cover body 2 is installed on the top of the lamp housing 11 through threads, and a conical block 23 slides in the truncated cone groove 22 on the cover body 2, when the lamp body 1 is installed, the power cord 12 is passed through the conical block 23, and then the cover body 2 is tightened on the lamp housing 11. In the process of tightening the cover body 2, the conical block 23 in the truncated cone groove 22 on the cover body 2 will fit with the top of the lamp housing 11. As the truncated cone groove 22 on the lamp housing 11 gradually approaches the top of the lamp housing 11, the truncated cone groove 22 will gradually squeeze the conical block 23. Since the maximum diameter of the conical block 23 is greater than the maximum diameter of the truncated cone groove 22, the truncated cone groove 22 will gradually squeeze the conical block 23 to fit with the power cord 12, so that the conical block 23 can squeeze the power cord 12, thereby improving the sealing effect of the power cord 12.

[0085] More specifically, since a retaining ring 24 is provided under the cover body 2, and the limiting rod 41 passes through the first through hole 21 and extends into two of the second through holes 25, when the lamp housing 11 moves upward, the retaining ring 24 and the cover body 2 will be driven to move upward along the limiting rod 41. At the same time, since the limiting rod 41 passes through the first through hole 21 and the second through hole 25, the limiting rod 41 can limit the lamp housing 11 and the cover body 2 to prevent the cover body 2 or the lamp housing 11 from rotating, resulting in the cover body 2 no longer squeezing the conical block 23, thereby reducing the sealing effect on the power cord 12.

[0086] Embodiment 4: The rotating ring 32 comprises an upper half ring 321 and a lower half ring 322, and half of the annular groove 33 is located in the upper half ring 321 and the other half is located in the lower half ring 322;

[0087] The bottom end surface of the lower half ring 322 is provided with uniformly arranged second countersunk holes 323; the bottom end surface of the upper half ring 321 is provided with uniformly arranged second thread grooves 324;

[0088] A hexagon socket bolt is disposed in the second countersunk hole 323, and the hexagon socket bolt is engaged in the second thread groove 324, thereby locking and fixing the upper half ring 321 and the lower half ring 322;

[0089] Specifically, when the LED lamp needs to be maintained, first the hexagon socket bolt in the second countersunk hole 323 is screwed down from the second threaded groove 324. When the hexagon socket bolt in the second countersunk hole 323 is removed, the lower half ring 322 is separated from the upper half ring 321. Then the maintenance personnel pulls the protective shell 3 downward in the protective cover 4, and the limiting rod 41 is gradually moved out of the first through hole 21 and the second through hole 25. When the protective shell 3 and the cover body 2 on the lamp body 1 are separated from the limiting rod 41, The maintenance personnel first rotate the cover body 2, and when the cover body 2 is rotated off from the lamp housing 11, the hexagon socket bolts in the first countersunk holes 26 are then rotated off from the first threaded grooves 27. When all the hexagon socket bolts in the first countersunk holes 26 are rotated off, the retaining ring 24 is no longer fixed on the lamp housing 11. Then the retaining ring 24 is pushed upward and moved to the top of the lamp housing 11. Then the lamp housing 11 is controlled to slide downward in the protective housing 3, and the lamp body 1 can be taken out, and then the lamp body 1 can be maintained.

[0090] More specifically, when the maintenance of the lamp body 1 is completed, the lamp housing 11 is first passed through the bottom of the protective shell 3. When the top of the lamp housing 11 moves to the top of the protective shell 3, the retaining ring 24 is put on the lamp housing 11, and the retaining ring 24 is fixed to the lamp housing 11 with the hexagon socket bolts. Then the cover body 2 is rotated on the top of the lamp housing 11. When the cover body 2 is tightened, the first through hole 21 is controlled to coincide with the second through hole 25.
