Abstract
Description

[0031] The technical solution of the embodiment of the present application is briefly described below:
[0032] According to some embodiments, Figure 1 to Figure 2 As shown, the present application provides an explosion-proof ceiling lamp, which includes:
[0033] Protective cover 1, such as Figure 5 As shown, the protective cover 1 includes a mesh cover 2 and an annular semi-groove 3, and the edge of the mesh cover 2 is connected to the outer bottom of the annular semi-groove 3;
[0034] Transparent cover 4, such as Figure 4As shown, the outer side of the cover opening of the light-transmitting cover 4 is provided with a thread, and the lower end of the outer side of the cover opening of the light-transmitting cover 4 is connected to an annular stopper 5. Figure 1 As shown, the protective cover 1 is sleeved on the outer side of the light-transmitting cover 4. The annular limit block 5 is connected to the inner bottom of the annular semi-groove 3;
[0035] A light source board 6, which is disposed in the light-transmitting cover 4;
[0036] A back groove 7, the back groove 7 is provided with a wire hole, the inner side of the notch of the back groove 7 is provided with a thread, and the notch of the back groove 7 is threadedly connected with the cover opening of the light-transmitting cover 4;
[0037] The sealant is filled into the groove formed by the outer wall of the groove opening of the back groove 7, the annular limiting block 5 and the annular half groove 3.
[0038] The sealant is used to prevent the inflammable gas and dust from entering the light-transmitting cover 4 . Meanwhile, the sealant also connects the protective cover 1 , the light-transmitting cover 4 and the back groove 7 together.
[0039] In the present application, the protective cover 1 is sleeved on the outside of the light-transmitting cover 4. The protective cover 1 is made of metal and has high hardness. When an explosion occurs inside the lamp, the protective cover 1 can slow down or prevent the light-transmitting cover 4 from splitting and popping out, thereby greatly reducing the damage caused by the explosion of the lamp to surrounding users.
[0040] The following is combined with the appendix of this manual Figures 1 to 5 , the preferred implementation modes of the present disclosure are further elaborated in detail.
[0041] According to some embodiments, Figure 2 , Figure 5 As shown, the inner side wall of the annular semi-groove 3 is provided with a plurality of clamping blocks 8 .
[0042] Specifically, Figure 5 As shown, the block 8 is formed by the side wall of the annular half groove 3 being recessed inward. The function of the block 8 is that when the sealant is filled into the groove formed by the outer wall of the notch of the back groove 7, the annular stopper 5 and the annular half groove 3, after the sealant solidifies, the block 8 is bonded to the solidified sealant, and the block 8 is also engaged with the solidified sealant, thereby improving the stability of the connection of the protective cover 1.
[0043] According to some embodiments, Figure 5 As shown, a plurality of first screw holes 9 are formed on the side wall of the annular half groove 3 , and the explosion-proof ceiling lamp further comprises a plurality of first screws 10 corresponding to the number of the plurality of first screw holes 9 , and the first screws 10 are pressed against the notches of the back groove 7 through the first screw holes 9 .
[0044] Specifically, Figure 5As shown, the first screw hole 9 is arranged at the lower end of the clamping block 8. When the protective cover 1 is sleeved on the outer side of the light-transmitting cover 4, the first screw 10 is screwed into the first screw hole 9. After the first screw 10 is screwed into the first screw hole 9, the notch of the back groove 7 is pressed tightly, so that the protective cover 1 and the back groove 7 are clamped together through the first screw 10. When the sealant falls off, the first screw 10 will slide onto the annular limit block 5 and be clamped together with the annular limit block 5, thereby improving the stability of the connection of the protective cover 1.
[0045] The present application uses sealant to bond the protective cover 1, the light-transmitting cover 4 and the notch of the back groove 7; uses the clamping block 8 to clamp the protective cover 1 with the condensed sealant; and also clamps the protective cover 1 with the back groove 7 with the first screw 10; when the sealant falls off, the first screw 10 will slide onto the annular limit block 5 and clamp the annular limit block 5, so that the protective cover 1 will not fall off. The stability and safety of the connection of the protective cover 1 are improved as a whole.
[0046] According to some embodiments, Figure 4 As shown, a plate groove 11 is provided in the light-transmitting cover 4, and a plurality of second screw holes 12 are evenly spaced at the upper end of the edge of the plate groove 11. The explosion-proof ceiling lamp also includes a plurality of second screws 13 corresponding to the number of the plurality of second screw holes 12. The light source board 6 is installed in the plate groove 11, and the second screws 13 press the light source board 6 through the second screw holes 12.
[0047] Specifically, Figure 4 As shown, after the light source board 6 is installed in the board groove 11 , the second screw 13 is screwed into the second screw hole 12 , and the second screw 13 presses the light source board 6 through the second screw hole 12 to prevent the light source board 6 from shifting.
[0048] According to some embodiments, the wire holes include a live wire hole, a first neutral wire hole and a second neutral wire hole. The live wire hole and the first neutral wire hole are opened on the side wall of the back groove 7 , and the second neutral wire hole is opened on the top of the back groove 7 .
[0049] Further, such as Figures 1 to 3 As shown, the wire hole also includes a live wire sealing channel 14, a first neutral wire sealing channel 15 and a second neutral wire sealing channel 16. The live wire sealing channel 14 is connected to the live wire hole, the first neutral wire sealing channel 15 is connected to the first neutral wire hole, and the second neutral wire sealing channel 16 is connected to the second neutral wire hole.
[0050] According to some embodiments, Figure 1 to Figure 2 As shown, both ends of the top of the back groove 7 are connected with hanging pieces 17 , and hanging holes 18 are opened on the hanging pieces 17 .
[0051] The explosion-proof ceiling lamp can be hung on a hook on the ceiling through the hanging hole 18, or a screw can be passed through the hanging hole 18 and then threadedly connected to the ceiling, etc. The hanging method is not limited.
