Detailed implementation manners

[0022] 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.

[0023] The present utility model provides a technical solution: As Figures 1-6As shown in the figure, in this embodiment, a compression-resistant watertight door includes a compression-resistant watertight door mechanism 100 and a compression-resistant door boost assembly 200. The compression-resistant watertight door mechanism 100 includes a compression-resistant outer door 101 and a compression-resistant inner door 103. A moving groove 202 is provided inside the compression-resistant inner door 103. A moving housing 209 is installed inside the moving groove 202. A through hole is provided inside the moving housing 209. One end of the moving housing 209 is connected and fixed to a groove fixing block 204 by screws. One end of the groove fixing block 204 penetrates inside one end of the moving housing 209. One end of the groove fixing block 204 is connected and fixed to a motor 212 by bolts. The motor 212 is installed inside the moving housing 209. A threaded lead screw 211 is installed at one end of the motor 212. The threaded lead screw 211 is rotationally connected inside a fixed sleeve 210. A threaded groove is provided inside the fixed sleeve 210. One end of the fixed sleeve 210 is connected to one end of a connecting block 213 by bolts. The connecting block 213 is provided at one end inside the compression-resistant inner door 103. One end of the groove of the groove fixing block 204 is connected and fixed by penetrating one end of a crankshaft connecting rod 201 through a rotating bolt 205. And the crankshaft connecting rod 201 can rotate on the rotating bolt 205.

[0024] As Figures 1-2 shown, one end of the crankshaft connecting rod 201 is fixedly installed at one end side of a compression-resistant door frame 104 through a hinge assembly 300. The hinge assembly 300 includes a second fixing bolt 304. The second fixing bolt 304 penetrates inside a second fixing block 305 and connects and fixes one end of the crankshaft connecting rod 201. The crankshaft connecting rod 201 can rotate on the second fixing bolt 304. The second fixing block 305 is connected to one end of the compression-resistant door frame 104 by welding. The hinge assembly 300 includes a first fixing block 302. The first fixing block 302 is connected to one end of the compression-resistant door frame 104 by welding. A first fixing bolt 301 penetrates through the inside of the first fixing block 302. And the first fixing bolt 301 hingedly connects and fixes a connecting sleeve block 303. The connecting sleeve block 303 can rotate on the first fixing bolt 301. One end of the connecting sleeve block 303 is connected to one end of the compression-resistant outer door 101 by welding.

[0025] When the staff pushes the pressure-resistant outer door 101 and the pressure-resistant inner door 103, first, the pressure-resistant outer door 101 and the pressure-resistant inner door 103 are rotated and opened on the pressure-resistant door frame 104 by using the hinge assembly 300. However, due to the large weight of the pressure-resistant watertight door body, the staff may move slowly or even be unable to push it when opening the pressure-resistant watertight door. When the pressure-resistant outer door 101 and the pressure-resistant inner door 103 are pushed to open at an angle, the driving motor 212 drives the threaded lead screw 211 to rotate and rotate inside the fixed sleeve 210. Further, the threaded lead screw 211 will move out of the fixed sleeve 210, driving the moving housing 209, the motor 212, and the groove fixing block 204 to move inside the moving groove 202 of the pressure-resistant inner door 103. One end of the groove fixing block 204 rotates the crank connecting rod 201, and further, the crank connecting rod 201 rotates on the pressure-resistant door frame 104. Through the pressure-resistant door boosting assembly 200, the mechanism of driving the threaded lead screw 211 to rotate by the driving motor 212 has the effects of converting rotary motion into linear motion, effectively improving the door opening and closing efficiency, and reducing the labor intensity of the staff, etc. It can adjust the moving speed of the pressure-resistant outer door 101 and the pressure-resistant inner door 103 to ensure the quick and stable opening and closing of the pressure-resistant outer door 101 and the pressure-resistant inner door 103.

[0026] As Figures 1-2 , Figures 4-6 shown, one end of the pressure-resistant outer door 101 and the pressure-resistant inner door 103 is connected and fixed by bolts to the handle 102. A sliding groove 214 is opened inside the moving groove 202 of the pressure-resistant inner door 103. A waterproof ring 206 is sleeved outside the groove fixing block 204. The waterproof ring 206 is mainly made of materials such as silica gel, PU, PVC, and TPU, and is widely used in the waterproof requirements of different occasions. The waterproof ring 206 is connected by bolts to one end of the moving housing 209. The upper and lower ends of the moving housing 209 are connected and fixed by welding the second sliding rod 208 and the first sliding rod 207. The second sliding rod 208 and the first sliding rod 207 are slidably connected inside the sliding groove 214.

[0027] When the moving housing 209 of the pressure-resistant door boosting assembly 200 moves inside the moving groove 202, the second sliding rod 208 and the first sliding rod 207 can move inside the sliding groove 214, which can maintain the linear operation and stable function during the movement of the pressure-resistant door boosting assembly 200. The waterproof ring 206 can prevent liquid from entering the internal components of the pressure-resistant door boosting assembly 200 and avoid damage, etc.

[0028] The present utility model provides a compression-resistant watertight door, and the specific working principle is as follows: When the staff pushes the compression-resistant outer door 101 and the compression-resistant inner door 103, first, the compression-resistant outer door 101 and the compression-resistant inner door 103 are rotated and opened on the compression-resistant door frame 104 by using the hinge assembly 300. However, due to the large weight of the compression-resistant watertight door body, the staff may move slowly or even be unable to push when opening the compression-resistant watertight door during the pushing process. When the compression-resistant outer door 101 and the compression-resistant inner door 103 are pushed to open at an angle, the driving motor 212 drives the threaded screw rod 211 to rotate and rotate inside the fixed sleeve 210. Further, the threaded screw rod 211 moves out of the fixed sleeve 210, driving the moving housing 209, the motor 212, and the groove fixing block 204 to move in the moving groove 202 of the compression-resistant inner door 103. And one end of the groove fixing block 204 rotates the crank connecting rod 201. Further, the crank connecting rod 201 rotates on the compression-resistant door frame 104. Through the compression-resistant door boosting assembly 200, the mechanism of driving the threaded screw rod 211 to rotate by the driving motor 212 has the effects of converting rotational motion into linear motion, effectively improving the door opening and closing efficiency and reducing the labor intensity of the staff, etc. It can adjust the moving speeds of the compression-resistant outer door 101 and the compression-resistant inner door 103 to ensure the rapid and stable opening and closing of the compression-resistant outer door 101 and the compression-resistant inner door 103. When the moving housing 209 of the compression-resistant door boosting assembly 200 moves inside the moving groove 202, it can move inside the sliding groove 214 through the second sliding rod 208 and the first sliding rod 207, which can maintain the linear operation and stable effect during the movement of the compression-resistant door boosting assembly 200. The waterproof ring 206 can prevent liquid from entering the internal components of the compression-resistant door boosting assembly 200 to avoid damage, etc.
