[0021] See also Figure 1-5 A hydraulic pump for easy cleaning of an impeller includes a mounting mechanism 1, the mounting mechanism 1 includes a housing 101, a cover plate 102 is provided on one side of the housing 101, a combination hole 103 is provided on the surface of the housing 101 and the cover plate 102, and a limiting mechanism 2 and a fixing mechanism 3 are installed on the surface of the housing 101;

[0022] The housing 101 is used to protect the impeller, the cover plate 102 is used to be combined with the housing 101 , the limiting mechanism 2 is used to disassemble and assemble the housing 101 and the cover plate 102 , and the fixing mechanism 3 is used to limit the cover plate 102 .

[0023] The limiting mechanism 2 includes a mounting shell 201, two mounting shells 201, and the mounting shells 201 are fixed to the upper and lower sides of the surface of the outer shell 101. A first spring 202 is fixed to the inner wall of the mounting shell 201, and a sliding block 203 is fixed to the surface of the first spring 202. The surface of the sliding block 203 is rotatably connected to a rotating shaft 204, and a connecting block 205 is fixed to the surface of the rotating shaft 204. A baffle 206 is fixed to the surface of the connecting block 205, and a positioning rod 207 is fixed to the surface of the baffle 206. A second spring 208 is fixed to the surface of the mounting shell 201, and a pull plate 210 is fixed to the surface of the second spring 208. A limiting rod 209 is fixed to the surface of the pull plate 210, and the limiting rod 209 passes through the mounting shell 201. Two positioning holes 211 are provided on the surface of the sliding block 203.

[0024] When the cover 102 is fitted with the surface of the shell 101, the baffle 206 will fit with the surface of the cover 102 to block the surface of the cover 102 to prevent the cover 102 from separating from the shell 101, and the positioning rod 207 will be able to be located inside the combination hole 103 on the surface of the cover 102 and the shell 101, so that the cover 102 will not move on the surface of the shell 101. At the same time, the first spring 202 can always apply a pulling force to make the baffle 206 drive the cover 102 to fit closely with the surface of the shell 101. When the cover 102 needs to be removed, the pull plate 210 is pulled to stretch the second spring 208, and then the limit rod 209 will be separated from the positioning hole 211, so that the sliding block 203 When the sliding block 203 is moved to the side where the positioning hole 211 is located on the side of the limiting rod 209, the second spring 208 will shrink automatically to allow the limiting rod 209 to enter the positioning hole 211, so that the stretched sliding block 203 can be automatically positioned. At this time, the connecting block 205 will be located outside the mounting shell 201, and then the baffle 206 can be rotated so that the baffle 206 no longer blocks the cover plate 102, so that the operator can disassemble the outer shell 101 and the cover plate 102 without tools, so that the operator can more easily take out the impeller for cleaning.

[0025] Further, the fixing mechanism 3 includes an assembly shell 301 and a connecting plate 302. There are four assembly shells 301. The assembly shells 301 are fixed to both sides of the surface of the outer shell 101. The connecting plate 302 is fixed to the surface of the baffle 206. The surface of the assembly shell 301 is rotatably connected with a U-shaped plate 304. The surface of the assembly shell 301 is provided with a slot for matching the U-shaped plate 304. The surface of the connecting plate 302 is provided with a limiting groove 303 for matching the U-shaped plate 304.

[0026] When the surface of the baffle 206 is in contact with the surface of the cover plate 102, the connecting plate 302 will be located inside the assembly shell 301. At this time, the U-shaped plate 304 is rotated into the limiting groove 303, so that the connecting plate 302 can be limited, so that the baffle 206 cannot be removed from the surface of the cover plate 102, thereby increasing the limiting effect of the cover plate 102.

[0027] Furthermore, a side plate 305 is slidably penetrated through the surface of the assembly shell 301;

[0028] After the U-shaped plate 304 is rotated into the groove of the assembly shell 301, the side plate 305 is inserted into the surface of the assembly shell 301, so that the U-shaped plate 304 can be limited, thereby preventing the U-shaped plate 304 from falling out of the groove by itself.

[0029] Further, the first spring 202 and the second spring 208 are both tension springs;

[0030] By setting the first spring 202 and the second spring 208 , it is ensured that the sliding block 203 can move normally toward the inside of the mounting shell 201 , so that the baffle 206 can clamp the cover 102 , and the pull plate 210 can move toward the position of the sliding block 203 by itself.

[0031] Furthermore, one end of the limiting rod 209 and the positioning rod 207 are both arranged in a semicircular structure;

[0032] By setting the limiting rod 209 and the positioning rod 207 , the limiting rod 209 and the positioning rod 207 can pass through their semicircular surfaces to more easily enter the positioning hole 211 and the inner wall of the combination hole 103 .

[0033] Furthermore, a sliding rod 212 is slidably penetrated through the surface of the pull plate 210, and one end of the sliding rod 212 is fixedly connected to the surface of the mounting shell 201;

[0034] When the pull plate 210 moves, the slide bar 212 will slide on the surface of the pull plate 210, so that the pull plate 210 has a guiding effect when moving.

[0035] Furthermore, anti-slip plates 306 are fixed on both upper and lower sides of the side plate 305, and a sliding groove for cooperating with the anti-slip plates 306 is provided on the surface of the assembly shell 301;

[0036] After the side plate 305 is inserted into the surface of the assembly shell 301 , the anti-slip plate 306 will enter the inside of the slide groove, thereby preventing the side plate 305 from detaching from one side of the surface of the assembly shell 301 .

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
