Technical Field
[0001] The utility model relates to the technical field of lighting equipment, in particular to a mining lighting device with a protection function. Background Technique
[0002] The miner's lamp is the abbreviation of mining lamps or industrial and mining lamps, which is applicable to the places with the risk of gas and coal dust explosion in coal mines; the roadway in the bottom mining area, and can also be used in the roadway and chamber of the infrastructure mine with relatively large water spray. It is mainly used for safe lighting and emergency rescue lighting in environments with flammable, explosive and combustible gases such as mines, petroleum, chemical industry, railways, transportation, warehousing, etc.
[0003] When mining operations are carried out in a mine tunnel, the lighting device is an essential equipment. Usually, a layer of lens is arranged on the lamp beads of the lighting device in the prior art. Since coal dust will fly in the mine tunnel during the coal mining process and the lens of the lighting lamp is directly exposed to the outside, it is easy for the lens of the lighting lamp to adhere to coal dust. At this time, due to the coal dust covering the lens on the lighting lamp, its light transmittance becomes poor, and the coal dust is difficult to wipe clean by hand, thus affecting the lighting effect of the lighting lamp. Content of the Utility Model
[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and provide a mining lighting device with a protection function.
[0005] To achieve the above purpose, the utility model provides the following technical scheme: a mining lighting device with a protection function, including a battery box and an elastic strap. The front of the battery box is hinged with a lighting lamp, and further includes:
[0006] A protection structure, which is arranged on the front of the lighting lamp and is used to prevent coal dust from covering the lens of the lighting lamp;
[0007] Among them, the protection structure includes a fixed ring. A first circular plate is sleeved inside the fixed ring. Several groups of glass sheets are arranged in the middle of the fixed ring. A first chute is opened on the front of the fixed ring. A second chute is opened on the outer surface of the fixed ring. A connecting head is installed on the outer surface of the first circular plate. A notch is opened inside the connecting head. A fixed shaft is installed inside the notch. A movable part and a return spring are sleeved on the outer surface of the fixed shaft. A limiting part is installed on the outside of the movable part. An extrusion part is installed on the top of the movable part. A second circular plate is threadedly connected to the front of the fixed ring. Three circular holes are opened in the middle of the second circular plate.
[0008] The above-mentioned limiting part is slidably matched with the inner wall of the first chute, and the limiting part is movably clamped with both ends of the first chute.
[0009] The above-mentioned return spring elastically supports between the notch and the movable part.
[0010] As described above, the connector is slidably engaged with the second chute. When the limiting member is located at both ends of the first chute, the positions of the round holes correspond to those of the glass sheets.
[0011] As described above, the top of the pressing member passes through the connector and is sleeved with the connector, and the elastic band is tied to the user's head or safety helmet.
[0012] As described above, the end of the limiting member passes through the notch and is slidably engaged with the notch. The second circular plate contacts the first circular plate, and a sponge is bonded to the contact surface between the second circular plate and the first circular plate.
[0013] Compared with the prior art, the mining lighting device with a protection function has the following beneficial effects:
[0014] First, through the cooperation between the connector and the second chute, the present invention can drive the first circular plate to rotate along the inside of the fixed ring. At the same time, due to the elastic force of the return spring, the movable member will be driven to move upward along the outer surface of the fixed shaft and drive the limiting member to be engaged with the first chute. Thus, when one group of glass sheets is contaminated, different glass sheets can be switched to avoid affecting the lighting effect.
[0015] Second, due to the sponge provided on the contact surface between the second circular plate and the first circular plate, when the first circular plate rotates, the sponge will wipe the glass sheets. Therefore, during the process of switching the glass sheets, the glass sheets can be cleaned. At the same time, through the cooperation between the second circular plate and the fixed ring, the glass sheets can be disassembled, which is convenient for replacing the sponge attached to the surface of the glass sheets.
[0016] Other advantages, objectives, and features of the present invention will be described to some extent in the subsequent description, and to some extent, will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the present invention.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] As Figures 1-5 shown, the present utility model provides a mining lighting device with a protection function, including a battery box 1 and an elastic strap 2. A lighting lamp 3 is hinged to the front of the battery box 1, and further includes:
[0025] A protection structure, which is arranged on the front of the lighting lamp 3 and is used to prevent coal dust from covering the lens of the lighting lamp 3;
[0026] Among them, the protection structure includes a fixed ring 4. A first disc 5 is sleeved inside the fixed ring 4. Several groups of glass sheets 6 are arranged in the middle of the fixed ring 4. A first chute 7 is opened on the front of the fixed ring 4. A second chute 8 is opened on the outer surface of the fixed ring 4. A connector 9 is installed on the outer surface of the first disc 5. A notch 10 is opened inside the connector 9. A fixed shaft 11 is installed inside the notch 10. A movable part 12 and a return spring 13 are sleeved on the outer surface of the fixed shaft 11. A limiting part 14 is installed on the outside of the movable part 12. An extrusion part 15 is installed on the top of the movable part 12. A second disc 16 is threadedly connected to the front of the fixed ring 4. Three round holes 17 are opened in the middle of the second disc 16.
[0027] Through the round holes 17, three of the glass sheets 6 are exposed to the outside. When the glass sheets 6 exposed to the outside are contaminated with coal powder and affect the light transmittance, through the cooperation between the connector 9 and the second chute 8, the first disc 5 can be driven to rotate along the inside of the fixed ring 4. At the same time, due to the elastic force of the return spring 13, the movable part 12 will be driven to move upward along the outer surface of the fixed shaft 11 and drive the limiting part 14 to be engaged with the first chute 7, so as to be able to switch different glass sheets 6 and avoid affecting the lighting effect.
[0028] As Figure 5As shown, the limiting member 14 is slidably engaged with the inner wall of the first chute 7, and the limiting member 14 is movably clamped at both ends of the first chute 7.
[0029] Through the cooperation between the limiting member 14 and the first chute 7, the connecting head 9 can drive the limiting member 14 to slide along the inner side of the first chute 7. When the limiting member 14 is located at both ends of the first chute 7, the elastic force of the return spring 13 will drive the limiting member 14 to be clamped with the first chute 7, so that the first disc 5 can be limited by the connecting head 9.
[0030] As Figure 5 shown, the return spring 13 is elastically supported between the notch 10 and the movable member 12.
[0031] Through the design of the return spring 13, the movable member 12 has good elastic reset performance. At this time, since the return spring 13 is in a compressed state, a elastic force will be applied to the movable member 12, so that the cooperation between the limiting member 14 and the first chute 7 can be made closer.
[0032] As Figure 2 、 3 shown in FIGS. 5, the connecting head 9 is slidably engaged with the second chute 8. When the limiting member 14 is located at both ends of the first chute 7, the positions of the round holes 17 and the glass sheet 6 correspond to each other.
[0033] Through the design of the limiting member 14, when the limiting member 14 is located at both ends of the first chute 7, it will limit the first disc 5, and when the limiting member 14 is at different positions at both ends of the first chute 7, different glass sheets 6 can be switched.
[0034] As Figure 1 、 5 shown, the top of the pressing member 15 passes through the connecting head 9 and is sleeved with the connecting head 9, and the elastic band 2 is tied to the user's head or safety helmet.
[0035] Through the design of the pressing member 15, when the pressing member 15 is pressed, it will drive the movable member 12 to move along the outer surface of the fixed shaft 11, so that the limiting member 14 can be disengaged from both ends of the first chute 7.
[0036] As Figure 5 shown, the end of the limiting member 14 passes through the notch 10 and is slidably engaged with the notch 10. The second disc 16 contacts the first disc 5, and a sponge is bonded to the contact surface between the second disc 16 and the first disc 5.
[0037] Through the design of the second wafer 16, it can be installed on or disassembled from the front surface of the fixed ring 4. At the same time, due to the sponge provided on the contact surface between the second wafer 16 and the first wafer 5, when the first wafer 5 rotates, the sponge will wipe the glass sheet 6, so as to clean the glass sheet 6 during the process of switching the glass sheet 6.
[0038] Working principle:
[0039] When one group of the glass sheets 6 is contaminated by pulverized coal, the user can press the extrusion member 15 to drive the limiting member 14 to separate from both ends of the first sliding groove 7. At the same time, through the cooperation between the connecting head 9 and the second sliding groove 8, the first wafer 5 can be driven to rotate along the inside of the fixed ring 4, so that the glass sheet 6 can be driven to rotate by the first wafer 5. Then the user releases the extrusion member 15. At this time, due to the elastic force of the return spring 13, the movable member 12 will be driven to move upward along the outer surface of the fixed shaft 11 and drive the limiting member 14 to be engaged with the first sliding groove 7, so as to switch different glass sheets 6 and avoid affecting the lighting effect.
[0040] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
