[0035] In this embodiment: the electric control cabinet of the filtering equipment is mainly divided into two parts: the fixed plate 1 and the cabinet body 2. When the device is in use, firstly, the cabinet body 2 is made to be close to the fixed plate 1 and the telescopic swing arm 104 is stored in the swing cavity 103, and then the side door panels 203 on both sides are closed, and the inner insert block 247 is inserted into the inner slot 221. Finally, the front door panel 204 is closed. When the front door panel 204 is closed, the front door panel 204 will squeeze the squeezing column 225, and the driving rod 224 is squeezed to move inward along the lifting cavity 211. When the driving rod 224 moves inward, the gears 227 on both sides drive the horizontal locking member 226 to move to both sides. When the horizontal locking member 226 is locked into the horizontal hole 1 240 and squeezes the bottom of the swing plate 242, the swing plate 242 swings outward. When the side door plate 203 is closed, the inner insert block 247 is inserted into the inner slot 221, and the swing plate 242 squeezes the extrusion piece 243 outward. Therefore, the extrusion piece 243 squeezes the linkage plug-in 236 outward, and the linkage plug-in 236 moves outward along the connecting groove 222 and is inserted into the limiting groove 248. Since the linkage ring 229 is threadedly connected with the threaded rod 249, the horizontal locking pieces 226 on both sides move inward along the horizontal slideway 216 and the vertical slideway 218 and are inserted into the locking cavity 102 under the drive of the threaded rod 249.

[0036] See attached Figure 2 -Attached Figure 3 A sliding cover 207 is slidably provided on the top of the linkage mechanism 201 located below, a symmetrical T-shaped slide rail 208 is provided on the bottom of the slide cover 207, a T-shaped slide groove 209 matching the T-shaped slide rail 208 is opened on the top of the linkage mechanism 201, and a purification device 210 is installed on the top of the slide cover 207.

[0037] In this embodiment, in order to further increase the degree of freedom and facilitate the maintenance and replacement of the purification device 210, a sliding cover 207 is designed.

[0038] See attached Figure 4 and attached Figure 6 A squeezing column 225 is arranged at the top of the driving rod 224, and a squeezing chamber 212 cooperating therewith is arranged at the top of the lifting chamber 211.

[0039] In this embodiment, when the extrusion column 225 is squeezed, an extrusion cavity 212 is designed to accommodate it.

[0040] See attached Figure 4 and attached Figure 6The vertical locking member 230 includes an upper sliding block 232 slidably set in the horizontal slide 216 and a lower sliding block 233 slidably set in the external plug-in block 217. The upper sliding block 232 is connected to the lower sliding block 233 through a connecting plate 234, and the connecting plate 234 is movably set in the vertical slide 218.

[0041] In this embodiment: when the extrusion column 225 is squeezed, since the linkage ring 229 is threadedly connected to the threaded rod 249, under the drive of the threaded rod 249, the linkage ring 229 will drive the vertical locking pieces 230 on both sides to move inward along the horizontal slide 216 and be inserted into the locking cavity 102.

[0042] See attached Figure 4 -Attached Figure 5 and attached Fig.10 -Attached Fig.11 Side door panels 203 are movably provided on both sides of the cabinet 2, a horizontal hole 240 cooperating with the horizontal locking piece 226 is provided on the inner wall of the cabinet 2, and a horizontal hole 241 communicating with the horizontal hole 240 is also provided on the inner wall of the cabinet 2; a swing plate 242 is installed between the horizontal hole 240 and the horizontal hole 241; an extrusion piece 243 is movably provided in the horizontal hole 241, and extrusion grooves 220 cooperating with the extrusion piece 243 are also provided on both sides of the linkage mechanism 201.

[0043] In this embodiment, when the horizontal locking member 226 is locked into the horizontal hole 1 240 and presses the lower part of the swing plate 242, the swing plate 242 swings outward. Since the inner insert block 247 is inserted into the inner slot 221, the swing plate 242 presses the extrusion member 243 outward. Therefore, the extrusion member 243 moves outward and enters the extrusion groove 220. At this time, the extrusion member 243 presses the linkage plug-in 236, and the linkage plug-in 236 moves outward along the connecting groove 222 and is inserted into the limiting groove 248, thereby completing the locking of the side door panels 203 on both sides.

[0044] See attached Figure 4 -Attached Figure 5 and attached Fig.10 -Attached Fig.11 An inner slot 221 is provided above the extrusion slot 220, and an inner insert block 247 cooperating with the inner slot 221 is fixedly provided on the inner wall of the side door panel 203; the inner slot 221 is connected with the extrusion slot 220 through a connecting slot 222, and a linkage plug-in 236 cooperating with the extrusion piece 243 is movably installed in the extrusion slot 220, and a limiting slot 248 cooperating with the inner insert block 247 is provided in the middle thereof.

[0045] In this embodiment: In order to facilitate locking and unlocking of the side door panel 203, thereby further realizing full opening and closing of the cabinet 2, and facilitating the inspection and replacement of the purification device 210, a matching inner slot 221 and inner insert block 247 structure are designed.

[0046] See attached Figure 5 -Attached Figure 7 and attached Fig.10 -Attached Fig.11 Symmetrical first reset grooves 223 are provided on the inner walls on both sides of the connecting groove 222, and convex plates 237 slidably disposed in the first reset grooves 223 are provided on both sides of the linkage plug-in 236, and a reset spring 238 is connected to the bottom of the convex plate 237. Symmetrical second reset grooves 244 are provided on the inner walls on both sides of the horizontal hole 241, and convex plates 245 slidably disposed in the second reset grooves 244 are provided on both sides of the extrusion piece 243, and a reset spring 246 is connected to the bottom of the convex plate 245.

[0047] In this embodiment: when the horizontal locking member 226 is unlocked, in order to ensure that the extrusion member 243 automatically returns to its original position, so that the linkage plug-in 236 automatically pops out from the limiting groove 248, a return spring 246 and a return spring 1 238 are designed.

[0048] See attached Figure 6 A reset member 235 is also installed at the bottom of the engagement groove 214, and the bottom of the threaded rod 249 abuts against the top thereof.

[0049] In this embodiment: when the front door panel 204 is opened, under the action of the reset member 235, the threaded rod 249 and the driving rod 224 move outward and return to their original positions. At this time, the gears 227 on both sides drive the horizontal locking member 226 to move inward. When the horizontal locking member 226 is separated from the horizontal hole 1 240, under the action of the reset spring 246, the extrusion member 243 is separated from the extrusion groove 220 and returns to its original position, and the swing plate 242 swings inward. Under the action of the reset spring 1 238, the linkage plug-in 236 is unlocked from the limit groove 248 and returns to its original position. Driven by the threaded rod 249, the horizontal locking members 226 on both sides move outward along the horizontal slide 216 and the vertical slide 218 and are unlocked from the locking cavity 102.

[0050] See attached Figure 1 A front door panel 204 is movably mounted on the front side of the cabinet 2 , and a handle 206 and an observation window 205 are also provided on the front door panel 204 .

[0051] In this embodiment, in order to facilitate observation of the internal conditions of the cabinet 2, an observation window 205 structure is designed. When the front door panel 204 is closed, the front door panel 204 will squeeze the extrusion column 225, and the driving rod 224 will be squeezed to move inward along the lifting chamber 211. When the driving rod 224 moves inward, the gears 227 on both sides drive the horizontal locking member 226 to move to both sides. When the horizontal locking member 226 is locked into the horizontal hole 1 240 and squeezes the bottom of the swing plate 242, the swing plate 242 swings outward. Since the inner insert block 247 is inserted into the inner slot 221 when the side door panel 203 is closed, the swing plate 242 squeezes the extrusion member 243 outward. Therefore, the extrusion member 243 will squeeze the linkage plug-in 236 outward, and the linkage plug-in 236 moves outward along the connecting groove 222 and is inserted into the limiting groove 248. Since the linkage ring 229 is threadedly connected to the threaded rod 249 , the horizontal locking members 226 on both sides will move inward along the horizontal slide 216 and the vertical slide 218 and be inserted into the locking cavity 102 under the drive of the threaded rod 249 .

[0052] Working principle of the present invention: When the device is used, firstly, the cabinet body 2 is made to be close to the fixed plate 1 and the telescopic swing arm 104 is stored in the swing cavity 103, and then the side door panels 203 on both sides are closed, and the inner insert block 247 is inserted into the inner slot 221. Finally, the front door panel 204 is closed. When the front door panel 204 is closed, the front door panel 204 will squeeze the squeezing column 225, and at this time, the driving rod 224 is squeezed to move inward along the lifting cavity 211. When the driving rod 224 moves inward, the gears 227 on both sides drive the horizontal locking member 226 to move to both sides. When the horizontal locking member 226 is locked into the horizontal hole 1 240 and squeezes the bottom of the swing plate 242, the swing plate 242 swings outward. Since the inner insert block 247 is inserted into the inner slot 221 when the side door panel 203 is closed, the swing plate 242 squeezes the squeezing member 243 outward. Therefore, the extrusion piece 243 will squeeze the linkage plug-in 236 outward, and the linkage plug-in 236 will move outward along the connecting groove 222 and be inserted into the limiting groove 248. Since the linkage ring 229 is threadedly connected with the threaded rod 249, the horizontal locking pieces 226 on both sides will move inward along the horizontal slideway 216 and the vertical slideway 218 and be inserted into the locking cavity 102 under the drive of the threaded rod 249.

[0053] When the front door panel 204 is opened, the front door panel 204 no longer squeezes the extrusion column 225. At this time, under the action of the reset member 235, the threaded rod 249 and the drive rod 224 move outward and return to their original positions. When the drive rod 224 moves outward, the gears 227 on both sides drive the horizontal locking member 226 to move inward. After the horizontal locking member 226 is separated from the horizontal hole 1 240, under the action of the reset spring 246, the extrusion member 243 is separated from the extrusion groove 220 and returns to its original position, and the swing plate 242 swings inward. Under the action of the reset spring 1 238, the linkage plug-in 236 is unlocked from the limit groove 248 and returns to its original position. Driven by the threaded rod 249, the horizontal locking members 226 on both sides move outward along the horizontal slide 216 and the vertical slide 218 and are unlocked from the locking cavity 102. Finally, the cabinet 2 is pulled outward as a whole through the telescopic swing arm 104 and the side door panels 203 on both sides are opened.
