[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0025] The following describes an embodiment of the utility model based on its overall structure.

[0026] An air pump that is easy to maintain and overhaul, such as Figure 1-6As shown, it includes a main assembly 100, and the main assembly 100 includes an air pump 110. A fixing plate 120 is welded on one side of the air pump 110. A mounting plate 130 is slidably connected to the inner wall of the fixing plate 120. A mounting assembly 200 is provided at the connection position between the fixing plate 120 and the mounting plate 130, and a sealing assembly 300 is provided inside the fixing plate 120. The mounting assembly 200 includes four groups of arc plates 210 arranged on the surface of the fixing plate 120. The four groups of arc plates 210 are welded at the connection positions with the fixing plate 120. A connecting rod 220 is fixedly connected to one end of the connecting rod 220 away from the arc plate 210 with a block 240. A spring recess is provided inside the fixing plate 120. Groove 231, the inner wall of the spring groove 231 is provided with a spring 230 sleeved on the surface of the connecting rod 220, a groove 241 matching the block 240 is opened inside the mounting plate 130, the side of the arc plate 210 away from the connecting rod 220 is fixedly connected with a support block 250, an inclined groove 251 is opened inside the support block 250, a matching inclined block 260 is arranged on one side of the inclined groove 251, an annular plate 270 is fixedly connected to the side of the inclined block 260 away from the support block 250, a threaded screw 280 is arranged on one side of the annular plate 270, a bearing is arranged at the connection position between the threaded screw 280 and the annular plate 270, and a connecting block 290 is rotatably arranged on the surface of the threaded screw 280.

[0027] When the air pump 110 needs to be inspected, the staff member screws the two sets of threaded screws 280 to drive the annular plate 270 to move under the action of the bearing, and the annular plate 270 drives the inclined block 260 to insert into the inclined groove 251, so that the support block 250 drives the connecting rod 220 to move synchronously through the arc plate 210, and the connecting rod 220 drives the block 240 to squeeze the spring 230, so that the block 240 disengages from the slot 241, and the limit on the mounting plate 130 is released. Then the staff member takes out the mounting plate 130 and inspects the inside of the air pump 110. The installation component 200 can effectively enable the staff to disassemble and assemble the air pump 110 conveniently and quickly, saving time and cost, thereby improving work efficiency. At the same time, the detachability of the air pump 110 also enables it to add or remove certain components according to different usage scenarios to adapt to different working environments or work requirements.

[0028] Please refer to Figures 1 to 4 The upper and lower ends of the mounting plate 130 are fixedly connected to the limiting plate 131 , and the supporting block 250 is fixedly connected to the surface of the fixing plate 120 .

[0029] The cooperation between the support block 250 and the threaded screw 280 can effectively prevent the annular plate 270 from moving due to accidental touch.

[0030] Please refer to Figure 5 and Figure 6The sealing assembly 300 includes two groups of piston cylinders 310 fixedly connected to the inside of the fixed plate 120, the inner wall of the piston cylinder 310 is slidably connected to the piston 320, a piston rod 330 is fixedly connected to one side of the piston 320, a return spring 340 is sleeved on the surface of the piston rod 330, a connecting tube 350 is provided on the surface of the piston cylinder 310, and an air bag 360 is fixedly connected to the side of the connecting tube 350 away from the piston cylinder 310.

[0031] When the mounting plate 130 is inserted into the inner wall of the fixing plate 120, the piston rod 330 is fitted and squeezed through the limiting plate 131, so that the piston rod 330 drives the piston 320 to pull up the return spring 340 and squeeze the gas inside the piston cylinder 310, so that the gas enters the airbag 360 through the connecting tube 350, causing the airbag 360 to expand, thereby effectively improving the sealing effect between the fixing plate 120 and the mounting plate 130, preventing the air pump 110 from leaking during use, causing the air pump 110 to fail to work normally.

[0032] Please refer to Figure 5 and Figure 6 The piston rod 330 is opposite to one side of the limiting plate 131 , and the airbag 360 is connected to a side of the fixing plate 120 away from the mounting plate 130 .

[0033] The mounting plate 130 is embedded in the fixing plate 120 , and the limiting plate 131 can effectively play a guiding role to prevent the mounting plate 130 from being offset.

[0034] When in use, when the mounting plate 130 is inserted into the inner wall of the fixing plate 120, the piston rod 330 is fitted and squeezed through the limiting plate 131, so that the piston rod 330 drives the piston 320 to pull up the return spring 340 and squeeze the gas inside the piston cylinder 310, so that the gas enters the airbag 360 through the connecting pipe 350, and the airbag 360 expands, which effectively improves the sealing effect between the fixing plate 120 and the mounting plate 130, and prevents the air pump 110 from leaking when in use, causing the air pump 110 to fail to work normally. When the air pump 110 needs to be repaired, the staff screws the two sets of threaded screws 280 to drive the annular plate 270 to move under the action of the bearing, and the annular plate 270 drives the inclined block 260 to insert into the inclined groove 251, so that The support block 250 drives the connecting rod 220 to move synchronously through the arc plate 210, and the connecting rod 220 drives the block 240 to squeeze the spring 230, so that the block 240 disengages from the slot 241, and releases the limit on the mounting plate 130. Then the staff takes out the mounting plate 130 and inspects the inside of the air pump 110. The installation component 200 can effectively enable the staff to disassemble and assemble the air pump 110 conveniently and quickly, saving time and cost, thereby improving work efficiency. At the same time, the detachability of the air pump 110 also enables it to add or remove certain components according to different usage scenarios to adapt to different working environments or work requirements. The parts not involved in the device are the same as the prior art or can be implemented using the prior art.
