[0031] The following will be combined with the drawings in the specification of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Referring to Figure 1 、 Figure 3 and Figure 5 , an embodiment provided by the present utility model: a coating drying device for civil air defense doors, including a bracket 1. Both the front and rear of the middle of the top surface of the bracket 1 are fixedly connected with first telescopic rods 2. The output ends of the two first telescopic rods 2 are fixedly connected with cover shells 3 respectively. The bottoms of the two cover shells 3 are slidably connected to the two sides of the top surface of the bracket 1. The top surface of the bracket 1 is fixedly connected with a heating box 18 and a blower 16. One side of the heating box 18 is communicated with the output end of the blower 16. A heating pipe 17 is fixedly connected inside the heating box 18. The input end of the blower 16 is fixedly connected with an air inlet pipe 22. The other side of the heating box 18 is fixedly connected with an air delivery pipe 19. The top of the air delivery pipe 19 is fixedly connected with a shunt pipe 24. Both the top and bottom of the shunt pipe 24 are fixedly connected with guide pipes 23, and both ends of the two guide pipes 23 are communicated with the cover shell 3. A driving assembly is arranged on one side of the bracket 1.

[0033] When drying the civil air defense door, drive the heating pipe 17 and the blower 16. The heating pipe 17 can be used to heat the air inside the heating box 18, and the blower 16 can be used to convey the air inside the box body 5 to the inside of the air delivery pipe 19. After the hot air passes through the shunt pipe 24, it will be ejected from both ends of the two guide pipes 23. At this time, the hot air can enter the cover shell 3 at multiple points, so the uniformity of the hot air distribution is improved, and further the drying quality of the coating of the civil air defense door can be improved.

[0034] Referring to Figure 5 , a cavity 20 is opened in the middle of the cover shell 3, and a plurality of air outlet openings 21 are opened inside the cover shell 3, and the guide pipes 23, the cavity 20 and the air outlet openings 21 are communicated with each other.

[0035] After the hot air enters the inside of the cover shell 3, it will first enter the cavity, and finally will be discharged from the air outlet openings 21, so the uniformity of the hot air distribution inside the cover shell 3 can be further improved.

[0036] Referring to Figure 1 and Figure 4 , the driving assembly includes a motor 9 and a slider 11. The motor 9 is fixedly connected to the middle of one side of the bracket 1. The output end of the motor 9 is fixedly connected with a threaded rod 10. The other end of the threaded rod 10 is rotatably connected to the middle of the other side of the bracket 1. The middle of the slider 11 is threadedly connected to the outside of the threaded rod 10. The outside of the slider 11 is slidably connected to the middle of the top surface of the bracket 1. A groove is opened in the middle of the top surface of the bracket 1, and the slider 11 is slidably connected in the groove.

[0037] The driving motor 9 can drive the threaded rod 10 to rotate, and the threaded rod 10 can drive the slider 11 to slide inside the bracket 1, so that the loading and unloading of the civil air defense door can be realized, avoiding the phenomenon that it is difficult to transport due to the heavy weight of the civil air defense door, which is beneficial to improving the operation efficiency.

[0038] Refer to Figure 1 One side of the top surface of the bracket 1 is fixedly connected with a second telescopic rod 12, and the output end of the second telescopic rod 12 is fixedly connected with a top plate 13.

[0039] By driving the second telescopic rod 12, the top plate 13 can be pushed out, and the position of the civil air defense door can be corrected by using the top plate 13 to avoid its position from being skewed.

[0040] Refer to Figure 1 and Figure 5 The bottom of the housing 3 is fixedly connected with a convex block 14, and the convex block 14 is slidably connected inside the bracket 1.

[0041] The movement direction of the housing 3 can be guided by using the convex block 14.

[0042] Refer to Figure 1 The bottom of the outside of the housing 3 is fixedly connected with an inclined plate 15, and the bottom of the inclined plate 15 is slidably connected to the top surface of the bracket 1.

[0043] The inclined plate 15 can play an auxiliary supporting role for the housing 3 to improve the stability of the housing 3.

[0044] Refer to Figure 1 and Figure 2 The middle of the top surface of the housing 3 is fixedly connected with an air outlet pipe 4, one side of the top surface of the housing 3 is fixedly connected with a box body 5, the top surface of one side of the box body 5 is fixedly connected with an exhaust pipe 8, one end of the air outlet pipe 4 is fixedly connected to the middle of one side of the box body 5, a filter plate 6 is arranged in the middle of the box body 5, and an adsorption plate 7 is arranged on one side of the middle of the box body 5.

[0045] Through the air outlet pipe 4, the redundant air inside the housing 3 can enter the purification box, and the air can be filtered through the filter plate 6 and the adsorption plate 7, and the harmful substances can be adsorbed, which can ensure the safety of the operation environment and the physical health of the staff.

[0046] Working principle: When in use, the driving motor 9 drives the threaded rod 10 to rotate. At this time, the slider 11 moves towards the motor 9. At this time, the slider 11 can move away from the housing 3. Then, place the air defense door after painting on the top surface of the slider 11. By driving the output ends of the two second telescopic rods 12 to extend, the two top plates 13 can be pushed out at this time. The positions of the air defense doors can be corrected by using the two top plates 13 so that they are in the middle of the slider 11. Then, drive the driving motor 9 to drive the threaded rod 10 to reverse, so that the slider 11 approaches the housing 3. When the slider 11 and the air defense door are between the two housings 3, drive the output ends of the first telescopic rods 2 on both sides of the bracket 1 to extend. At this time, the two housings 3 can be made to approach each other. When the two housings 3 are combined into one, drive the heating tube 17 and the fan 16 to operate. The hot air generated by the heating tube 17 can be blown into the interior of the air delivery pipe 19 by the fan 16. The hot air can enter the interiors of the two conduits 23 along the shunt pipe 24 through the air delivery pipe 19. Finally, the hot air will enter the interior of the housing 3. Through the cooperation of the conduits 23, the hot air can enter the interior of the housing 3 at multiple points, so that the hot air is evenly distributed inside the housing 3, thereby improving the drying quality. And after the hot air enters the interior of the housing 3, it will first enter the cavity and finally be discharged from the air outlet 21, which can further improve the even distribution of the hot air inside the housing 3. After the hot air enters the interior of the housing 3, the air can enter the interior of the purification box along the air outlet pipe 4. When the air flow enters the interior of the purification box, the air can be filtered by the filter plate 6, and the harmful substances contained in the air can be adsorbed by the adsorption plate 7, and finally discharged from the exhaust pipe 8, thus completing the air circulation. The filter plate 6 and the adsorption plate 7 can prevent harmful substances from being discharged with the air, thereby ensuring the safety of the working environment and the physical health of the staff. When the operation is over, first drive the output ends of the first telescopic rods 2 on both sides to retract. At this time, the two housings 3 can be separated. Finally, drive the driving motor 9 to drive the threaded rod 10 to move the air defense door out so that it is away from the housing 3. At this time, the air defense door can be removed to complete the drying operation.

[0047] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
