[0035] The present invention is described in detail below, and the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Reference Figure 1-Figure 14 As shown, a protective structure for industrial and mining lamps capable of unloading force comprises an annular flat plate 8 and a reflector 12, one side outer wall of the annular flat plate 8 is fixedly connected to the open side wall of the reflector 12, the outer peripheral wall of the reflector 12 is sleeved with an annular bag 13 tightly attached to its outer wall, the other side wall of the reflector 12 is fixed with an inner cylinder plate 18, a plurality of ridge plates 7 distributed in a circle with equal spacing are fixed between the annular flat plate 8 and the inner cylinder plate 18, an inner guard plate 9, an annular bone plate 3 and an outer guard plate 2 are fixed between every two adjacent ridge plates 7, and the annular bone plate 3 is fixed between the outer guard plate 2 and the inner guard plate 9, a movable groove 70 is opened on the inner peripheral wall of each ridge plate 7, a movable pressure block 14 is movably connected in the movable groove 70, a rubber strip 31 is connected between every two adjacent movable pressure blocks 14, and the movable pressure block 14 It can also be squeezed by the annular bag 13 to move into the movable groove 70 to match the expandability of the rubber strip 31 when it is squeezed. Each rubber strip 31 is located on the inner side of the annular bone plate 3 and a gap is left, so that the rubber strip 31 can slightly press against the outer annular bone plate 3 when it is squeezed by the annular bag 13 to provide a certain buffering effect. A screw ring 25 is welded to the outer wall of the annular flat plate 8, and an outer ring 1 is sleeved on the outside of the screw ring 25. A wave plate 28 is integrally formed on the inner circumferential wall of the outer ring 1. A number of inflatable undulators are provided on the annular flat plate 8. An outer cylinder plate 4 is sleeved on the outside of the inner cylinder plate 18. The inner cylinder plate 18 and the outer cylinder plate 4 are fixed by a connecting ring 5. A movable ring plate 19 is slidably provided between the inner cylinder plate 18 and the outer cylinder plate 4, and an air outlet gap 49 is left between the outer cylinder plate 4 and the inner guard plate 9.

[0037] Specific reference Figure 8-Figure 10As shown, when the mining lamp is slightly hit to the inner guard plate 9 and the outer guard plate 2, the annular capsule 13 will be slightly squeezed, the movable ring plate 19 will squeeze the spring 1 20, and the pressure-passing circular plate 22 will also slightly squeeze the return spring 212 to cushion the impact, so that the annular capsule 13 acts as a buffer. In this process, the rubber strip 31 will also be squeezed by the annular capsule 13 to provide a certain support to the annular bone plate 3, thereby reinforcing the inner guard plate 9 and the outer guard plate 2 and the connected annular bone plate 3 at the remaining unimpacted parts. When the inner guard plate 9 and the outer guard plate 2 are hit hard and form a depression, the annular bone plate 3 connected to the corresponding depressed position will also tend to be squeezed toward the annular capsule 13, and the corresponding rubber strip 31 will also press The annular bag 13, the concave position itself obviously squeezes the annular bag 13, the movable ring plate 19 will quickly compress the spring 20 until the plug 191 is pulled out of the air cavity 16, which can instantly relieve a part of the impact force, and the plug 191 will be reset by the spring 20 and reinserted into the air cavity 16 at the moment of removal, waiting for the next impact protection. Although the buffering effect gradually decreases, the annular bag 13 can still be put in a closed state again, and the annular bag 13 still maintains a certain protective effect. When the impacted part is different next time, the air pressure inside the annular bag 13 will also freely adjust to squeeze the concave part itself, so that the entire protective effect can be brought into the best state.

[0038] Further reference Figure 4 , Fig.12 and Fig.13 As shown, when the device is impacted and depressed and cannot be restored by the plasticity of the protective plates themselves, the limit blocks 6 on both sides can be manually pressed and held, and the outer ring 1 can be continuously rotated so that the inflatable oscillator can continuously inflate the annular bag 13. Due to the restriction of the limit blocks 6, the plug 191 cannot be separated from the air outlet cavity 16, so that the entire annular bag 13 gradually expands, and the depressed position that cannot be restored by itself is pushed outward, thereby realizing manual restoration of the mining lamp protective cover to prevent the next high-force impact.

[0039] The inflatable wave generator includes an outer cylinder 24, a connecting column 29 and a sliding protrusion 27. The outer cylinder 24 is fixedly inserted on the annular flat plate 8 and penetrates into the annular bag 13. A fixed ring piece 241 is integrally formed on the outer peripheral wall of one side of the outer cylinder 24, and a fixing ring 21 is welded to the outer wall of the other side of the outer cylinder 24. The inner wall of the fixing ring 21 is slidably connected with a pressure-passing circular plate 22. A return spring 212 is provided between the pressure-passing circular plate 22 and the inner wall of the fixing ring 21. An extrusion plate 23 is slidably provided on the inner wall of the outer cylinder 24. The outer wall of the extrusion plate 23 is fixed to the connecting column 29 on one side away from the fixing ring 21. The connecting column 29 is fixedly connected to the plane wall of the sliding protrusion 27. The convex circular surface wall of the sliding protrusion 27 contacts the wave plate 28. A spring 26 is provided between the fixed ring piece 241 and the sliding protrusion 27. The peripheral wall of the outer cylinder 24 is provided with a plurality of vents 240.

[0040] Reference Figure 4 and Figure 5 , it should be noted that regarding the inflatable wave device: when the top of the sliding protrusion 27 is pressed by the raised portion 281, the spring 26 contracts, the extrusion plate 23 is squeezed into the fixed ring 21, and at this time, the pressure-passing circular plate 22 will also be moved into the annular bag 13 by the air pressure, and the return spring 212 stretches until the extrusion plate 23 squeezes the gas inside the outer tube 24 and the fixed ring 21 connected to it into the annular bag 13; then when the sliding protrusion 27 is no longer pressed, the spring 26 is reset, and the connecting column 29 also drives the extrusion plate 23 to reset to the position of the vent hole 240 as the sliding protrusion 27 returns, the pressure-passing circular plate 22 will also retract into the fixed ring 21, and the return spring 212 will also change from an extended state to a contracted state until the vent hole 240 connects the outer tube 24 with the external air pressure, and the annular bag 13 is repeatedly inflated.

[0041] Specifically, a plurality of airbag inlet holes 130 are provided at the bottom of the annular bag 13, the fixing ring 21 is located inside the annular bag 13, the outer tube 24 is inserted into the airbag inlet hole 130, and a plurality of airbag outlet protrusions 131 are provided on the outer wall of the annular bag 13 on one side close to the connecting ring 5, each airbag outlet protrusion 131 is fixed with an air outlet cavity 16, the inner circumferential wall and the outer circumferential wall of the air outlet cavity 16 are integrally formed with a connecting plate 161, and the connecting plate 161 is bonded to the outer wall of the annular bag 13, so as to stably fix the air outlet cavity 16 and the annular bag 13, the outer tube plate 4 is slidably provided with a limit block 6, a plurality of springs 20 are provided between the outer wall of one side of the movable ring plate 19 and the connecting ring 5, and a plurality of plugs 191 are integrally formed on the outer wall of the other side of the movable ring plate 19, and each plug 191 is respectively inserted into the inside of the air outlet cavity 16.

[0042] Reference Fig.12 The specific principle of the movable ring plate 19 is as follows: when the annular bag 13 is frequently inflated until it is full and then continued to be inflated, the entire movable ring plate 19 will rise through the plug 191, that is, at this time the spring 20 is compressed until the plug 191 is separated from the air outlet cavity 16, and the high-pressure gas quickly emerges from the air outlet cavity 16 through the air outlet gap 49 to blow dust onto the surface of each inner guard plate 9.

[0043] Specifically, a groove that matches the screw ring 25 is opened on one side wall of the outer ring 1, and the groove is provided with oblique grooves 100 and horizontal grooves 101, so that when the outer ring 1 rotates around the screw ring 25, it can be connected to the screw ring 25 and can continue to rotate, so that the recessed part 282 of the wave plate 28 can frequently hit the inflatable wave device.

[0044] Among them, the rotation of the outer ring 1 can be connected to the screw ring 25 through the oblique grooves 100, and the horizontal grooves 101 can make the outer ring 1 continue to rotate when the oblique grooves 100 are screwed to the limit, so that the outer ring 1 can continue to rotate on the annular flat plate 8, so that the wave plate 28 frequently contacts the sliding protrusion 27.

[0045] A ring frame 32 is fixed to the outer wall of the inner cylinder plate 18, and a plurality of limiting holes 320 are opened on the ring frame 32. Each air outlet cavity 16 is movably inserted into the limiting hole 320 in a one-to-one corresponding manner; a circuit board 15 is fixed to the inner circumferential wall of the inner cylinder plate 18, and an energized lamp tube component is fixed on the circuit board 15. A fixing strip 71 is welded to the top of each ridge plate 7, and all the fixing strips 71 are fixed to the outer circumferential wall of the outer cylinder plate 4.

[0046] An inner glass plate 11 is fixed to the inner circumferential wall of the annular flat plate 8 by screws, and an outer glass plate 10 is fixed to the inner circumferential wall of the outer ring 1 by screws, and the outer glass plate 10 is located on one side of the plane wall of the wave plate 28 .

[0047] In addition, on the basis of protection, the present device can also achieve the effect of repeatedly squeezing the inflation oscillator to inflate by replacing the outer ring 1 connected to the outer glass plate 10 of the same model, or removing the outer glass plate 10 for inspection and wiping. When the annular bag 13 is continuously inflated until the upper limit, after the plug 191 is separated from the air outlet cavity 16, the internal high-pressure gas rushes out from the air outlet gap 49, blowing away the surface dust of each protective plate and the mining lamp, which has an additional effect on subsequent inspection and cleaning.

[0048] The above description enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
