Detailed implementation manners

[0025] 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.

[0026] The following gives specific embodiments.

[0027] Please refer to Figure 1 - Figure 6, the utility model provides a mine explosion-proof switch housing that can be quickly disassembled and assembled, including a switch body 1; a first sealing plate 11 is in sliding contact with the side wall of the switch body 1; a connecting plate 12 is fixedly connected to the inner side wall of the switch body 1; the connecting plate 12 is in contact with the first sealing plate 11; a plurality of first fixing columns 13 are fixedly connected to the side wall of the switch body 1; a first contact block 14 is slidably connected to the side wall of the first fixing column 13; a second contact block 15 is fixedly connected to the end of the first fixing column 13; a plurality of first spring columns 16 are provided on the inner side wall of the switch body 1; a first limiting block 17 is fixedly connected to the end of the first spring column 16; the first limiting block 17 is in contact with the second contact block 15; the first limiting block 17 is in contact with the first contact block 14. Slide the first sealing plate 11 in the direction of the first fixing column 13. When the first limiting block 17 contacts the second contact block 15, the first spring column 16 will be compressed. Continue to slide the first sealing plate 11 until the first limiting block 17 is located at the other end of the second contact block 15. The first spring column 16 pushes the first limiting block 17 to reset. At this time, the second contact block 15 limits the first limiting block 17, so that the first sealing plate 11 cannot be separated from the switch body 1. When the first sealing plate 11 is pushed again, the first limiting block 17 contacts the first contact block 14, and the first spring column 16 is compressed and contracts, and the first limiting block 17 moves. When the first limiting block 17 is located on the side wall of the first contact block 14, pull the first sealing plate 11, and the first contact block 14 will move with the first sealing plate 11 until the first contact block 14 contacts the second contact block 15. At this time, the first limiting block 17 can slide along the side wall of the first contact block 14, so as to disengage from the first contact block 14 and the second contact block 15, and the first sealing plate 11 is separated from the switch body 1. By providing the first contact block 14 and the second contact block 15, the first sealing plate 11 can be quickly installed and removed, reducing the time spent by the staff in screwing multiple bolts, reducing the difficulty of the staff in fixing the equipment housing, and facilitating the staff to disassemble the equipment housing.

[0028] Further, as Figure 1 and Figure 5As shown, the outer wall of the switch body 1 is fixedly connected to a support block 2; a pair of second spring columns 21 are fixedly connected to the side wall of the support block 2; a second limit block 22 is fixedly connected to the end of the second spring column 21; the second limit block 22 is in sliding contact with the switch body 1; a pair of fixed blocks 23 are fixedly connected to the outer wall of the switch body 1; a slider 24 is in sliding contact with the outer wall of the fixed block 23; a sliding column 25 is fixedly connected to the inner wall of the slider 24; the slider 25 is in sliding contact with the fixed block 23; the second limit block 22 is in contact with the slider 24; and the slider 24 is in contact with the first sealing plate 11. When the first sealing plate 11 is installed, the two sliders 24 are pushed until the slider 24 contacts the first sealing plate 11. At this time, the second spring column 21 will push the second limit block 22. When the second limit block 22 is at the bottom of the slider 24, the slider 24 cannot fall, thereby fixing the slider 24 to the first sealing plate 11. When the two second limit blocks 22 are pulled close to each other, when the second limit block 22 is separated from the bottom of the slider 24, the slider 24 will fall downward due to its own gravity. At this time, the slider 24 is separated from the fixation to the first sealing plate 11. By setting the second limit block 22 and the slider 24, the equipment can be assisted to fix the first sealing plate 11, further increase the stability of the first sealing plate 11, reduce the situation where the first sealing plate 11 is separated from the equipment due to accidental collision, and facilitate the use of the equipment by the staff.

[0029] Further, such as Figure 1 and Figure 3 As shown, the side wall of the first sealing plate 11 is slidably connected to the second sealing plate 3; the switch body 1 is provided with a storage slot 32; a pair of second support columns 31 are fixedly connected to the side wall of the first sealing plate 11; a handle 34 is rotatably connected to the side wall of the second support column 31; the second sealing plate 3 is in sliding contact with the storage slot 32; a pair of elastic fixing plates 35 are fixedly connected to the side wall of the first sealing plate 11; a lever 33 is fixedly connected to the top of the outer side wall of the second sealing plate 3; and the elastic fixing plate 35 is in contact with the lever 33. When the staff needs to remove the first sealing plate 11, they can move the lever 33 to move the second sealing plate 3 into the storage groove 32, and the elastic fixing piece 35 fixes the lever 33. At this time, the handle 34 can be pulled to drive the first sealing plate 11 through the handle 34. When use is completed, the second sealing plate 3 can be reset to cover the handle 34. The second sealing plate 3 and the handle 34 are set to facilitate the staff to pull the first sealing plate 11, and at the same time, the flatness of the surface of the first sealing plate 11 can be increased, thereby reducing the difficulty of the transportation process due to the uneven appearance during the transportation of the palletizing equipment.

[0030] Further, such as Figure 4As shown, a first contact plate 4 is fixedly connected to the bottom of the outer wall of the first sealing plate 11; a support plate 41 is fixedly connected to the inner wall of the switch body 1; a plurality of third spring columns 42 are fixedly connected to the side wall of the support plate 41; a second contact plate 43 is fixedly connected to the end of the third spring column 42; and the second contact plate 43 contacts the first contact plate 4. When installing the first sealing plate 11, the first contact plate 4 pushes the third spring columns 42 and the support plate 41. During the removal of the first sealing plate 11, the continued movement of the first sealing plate 11 will drive the first contact plate 4 to squeeze the second contact plate 43. During the detachment of the first sealing plate 11, the third spring columns 42 will release the accumulated potential energy, pushing the first sealing plate 11 outward. The provision of the third spring columns 42 and the first contact plate 4 can assist workers in removing the first sealing plate 11, making it easier for workers to use the equipment.

[0031] Further, such as Figure 4 As shown, the second contact plate 43 is made of rubber. When the device is working, the second contact plate 43 will contact the first contact plate 4. The rubber can cushion the contact process between the first contact plate 4 and the second contact plate 43. The second contact plate 43 can reduce the possibility of bending of the first contact plate 4 due to collision.

[0032] Further, such as Figure 3 As shown, several support rods 6 are fixedly connected to the inner sidewall of the switch body 1; these support rods 6 are in sliding contact with the first sealing plate 11. When the device is in operation, the support rods 6 support the first sealing plate 11. The presence of these support rods 6 increases the overall strength of the first sealing plate 11, reducing the risk of bending when objects fall and collide with the first sealing plate 11, thereby increasing the stability of the device.

[0033] Further, such as Figure 6 As shown, the inner sidewall of the switch body 1 is provided with a plurality of balls 7. These balls 7 rotate on the sidewall of the switch body 1 and cannot escape from the switch body 1. These balls 7 contact the first sealing plate 11. When the first sealing plate 11 moves, it preferentially contacts the balls 7. The balls 7 convert the sliding friction between the first sealing plate 11 and the switch body 1 into rolling friction. The provision of the balls 7 enhances the smoothness of the movement of the first sealing plate 11.

[0034] Working principle: Slide the first sealing plate 11 towards the direction of the first fixed column 13. When the first limiting block 17 contacts the second contact block 15, the first spring column 16 will be squeezed. When the first sealing plate 11 is continuously slid so that the first limiting block 17 is located at the other end of the second contact block 15, the first spring column 16 pushes the first limiting block 17 to reset. At this time, the second contact block 15 limits the first limiting block 17, thereby preventing the first sealing plate 11 from detaching from the switch body 1. When the first sealing plate 11 is pushed again, the first limiting block 17 contacts the first contact block 14, and the first spring column 16 is squeezed and contracts, and the first limiting block 17 moves. When the first limiting block 17 is located on the side wall of the first contact block 14, pulling the first sealing plate 11 will cause the first contact block 14 to move with the first sealing plate 11 until the first contact block 14 contacts the second contact block 15. At this time, the first limiting block 17 can slide along the side wall of the first contact block 14, thereby detaching from the first contact block 14 and the second contact block 15, and the first sealing plate 11 detaches from the switch body 1. By setting the first contact block 14 and the second contact block 15, the first sealing plate 11 can be quickly installed and removed, reducing the time spent by the staff in screwing multiple bolts, reducing the difficulty of the staff in fixing the equipment shell, and facilitating the staff to disassemble the equipment shell. When the first sealing plate 11 is installed, push the two sliders 24 until the sliders 24 contact the first sealing plate 11. At this time, the second spring column 21 will push the second limiting block 22. When the second limiting block 22 is located at the bottom of the slider 24, the slider 24 cannot fall, thereby fixing the first sealing plate 11 by the slider 24. When the two second limiting blocks 22 are pulled closer to each other, when the second limiting block 22 detaches from the bottom of the slider 24, the slider 24 will fall due to its own gravity. At this time, the slider 24 detaches from the fixation of the first sealing plate 11. By setting the second limiting block 22 and the slider 24, the equipment can be assisted in fixing the first sealing plate 11, further increasing the stability of the first sealing plate 11 and reducing the situation where the first sealing plate 11 detaches from the equipment due to accidental collision, facilitating the staff to use the equipment. When the staff needs to remove the first sealing plate 11, the lever 33 can be toggled so that the second sealing plate 3 moves into the storage groove 32, and the elastic fixing piece 35 forms a fixation on the lever 33. At this time, the handle 34 can be pulled, and then the first sealing plate 11 is driven through the handle 34. When in use, the second sealing plate 3 can be reset to cover the handle 34. By setting the second sealing plate 3 and the handle 34, it is convenient for the staff to pull the first sealing plate 11, and at the same time, the flatness of the surface of the first sealing plate 11 can be increased, reducing the difficulty of the transportation process due to the uneven shape during the transportation and stacking of the equipment. When the first sealing plate 11 is installed, the first contact plate 4 will push the third spring column 42 and the support plate 41. During the process of removing the first sealing plate 11, the continuous movement of the first sealing plate 11 will drive the first contact plate 4 to squeeze the second contact plate 43.During the process of the first sealing plate 11 being disengaged, the third spring post 42 will release the accumulated potential energy and push the first sealing plate 11 outwards. By providing the third spring post 42 and the first contact plate 4, it can assist the staff in removing the first sealing plate 11, facilitating the staff's use of the equipment. When the equipment is working, the second contact plate 43 will come into contact with the first contact plate 4, and the rubber can buffer the process of the first contact plate 4 and the second contact plate 43 coming into contact. By providing the second contact plate 43, the situation where the first contact plate 4 is bent due to collision can be reduced. When the equipment is working, the support rod 6 can support the first sealing plate 11. By providing the support rod 6, the overall strength of the first sealing plate 11 can be increased, and the situation where the first sealing plate 11 is bent when an object falls and collides with the first sealing plate 11 can be reduced, increasing the stability of the equipment. When the first sealing plate 11 moves, the first sealing plate 11 will first come into contact with the ball 7, and the ball 7 can change the sliding friction between the first sealing plate 11 and the switch body 1 into rolling friction. By providing the ball 7, the smoothness of the first sealing plate 11 during movement is increased.
