Description

Technical Field

[0001] This utility model relates to the field of three-cylinder pump technology, specifically a plug-in three-cylinder pump. Background Technology

[0002] The three-cylinder pump is a high-pressure reciprocating pump widely used in fields such as oil extraction, geological exploration, and mining engineering. It is characterized by the parallel operation of three piston / plunger cylinders to achieve a large displacement and high pressure fluid delivery capacity. In the existing technology, the three-cylinder pump is connected to the pipeline through flanges, bolts and nuts. During installation and dismantling, multiple bolts and nuts on the flange need to be operated one by one, which makes the installation and dismantling less than ideal.

[0003] For example, patent publication number CN221703901U describes a three-cylinder plunger pump, specifically in the field of plunger pump technology. The pump includes a three-cylinder plunger pump body, with a rotating wheel rotatably connected to one side. Support frames are fixedly connected to both sides of the bottom of the pump body. Through a buffer assembly and a filter assembly, when the plunger pump vibrates, a spring plate and a buffer spring work together. The spring plate and buffer spring utilize their elasticity to buffer the destructive force caused by the vibration, thus preventing the screws from loosening and affecting the service life of the plunger pump. Then, a motor drives a lead screw to rotate, which in turn drives a moving plate to reciprocate, opening the sealing plate. A cleaning brush then sweeps away the debris clogging the filter plate, ensuring the filter plate's filtration effect and preventing wear and tear caused by frequent disassembly of the filter plate, thus avoiding water leakage. However, this type of three-cylinder pump is connected to the pipeline via flanges, bolts, and nuts. Installation and removal require individually operating multiple bolts and nuts on the flange, making installation and removal less convenient. Utility Model Content

[0010] Preferably, the lever is rotatably connected to the inner wall of the handle via a pivot, and the bottom end of the lever extends into the groove, so that the lever can be used to push the movable block to move through the groove.

[0011] Preferably, the two return springs are respectively disposed between the lever and the inner wall of the handle and between the inner wall of the locking block and the movable block, and the end of the button passes through the handle and partially extends out of the handle, so that the lever can be rotated by pressing the button.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] The insertion mechanism 2 includes a connector 201 and a sleeve 202. Two sealing rings 203 are provided between the connector 201 and the sleeve 202. The sealing rings 203 are rubber rings with a certain degree of elasticity, allowing deformation when the connector 201 and sleeve 202 approach each other. This improves the sealing performance. Two limiting grooves 204 are formed on the surface of the connector 201, with locking grooves 205 at their ends. The two limiting grooves 204 are symmetrically arranged on the connector 201, perpendicular to each other, and connected to each other, allowing the locking block 209 to... The pin 211 enters the slot 205 through the limiting groove 204. A guide wedge 206 is fixedly connected inside the slot 205, and a locking block 207 is fixedly connected to the end of the guide wedge 206. The locking block 207 has a hole, allowing the pin 211 to be inserted into the hole for locking. The cross-sectional shape of the guide wedge 206 is a right-angled triangle, with its two right-angled sides connected to the slot 205 and the locking block 207 respectively. This allows the guide wedge 206 to push the locking block 209 to move using its inclined surface. Two handles 208 are fixedly connected to the sleeve 202, and two locking blocks 209 are fixedly connected to the inner wall of the sleeve 202. A movable block 210 is slidably connected inside the locking block 209. A pin 211 is fixedly connected to the end of the movable block 210. The two locking blocks 209 match the limiting groove 204 and the locking slot 205. The end of the pin 211 passes through the locking block 209 and extends partially to the outside, so that the pin 211 can be retracted into the locking block 209 and inserted into the locking block 207 for locking. A strip groove 213 is provided on the movable block 210. A lever 212 is provided on one side of the movable block 210. The lever 212 is rotatably connected to the inner wall of the handle 208 through a pivot. The bottom end of the lever 212 extends into the strip groove 213, so that the lever 212 can be used to lock the handle. 12 can push the movable block 210 to move through the strip groove 213, which can save effort. The end of the lever 212 away from the movable block 210 is provided with a button 214. Both the lever 212 and the movable block 210 are provided with a return spring 215. The two return springs 215 are respectively located between the lever 212 and the inner wall of the handle 208 and between the inner wall of the locking block 209 and the movable block 210. The two return springs 215 are used to reset the pin 211 and the lever 212 respectively. The end of the button 214 passes through the handle 208 and partially extends out of the handle 208, so that the lever 212 can be rotated by pressing the button 214.

[0025] Please see Figure 1 and Figure 5 The conveying mechanism 4 includes a drive motor 401. A crankshaft 402 is fixedly connected to the output shaft end of the drive motor 401. Three connecting rods 404 are mounted on the crankshaft 402. Connecting seats 403 are mounted on the ends of the three connecting rods 404. Each connecting seat 403 is fixedly connected to an installation screw 405. A piston 407 is sleeved on the installation screw 405. The drive motor 401 drives the crankshaft 402 to rotate. The rotation of the crankshaft 402 drives the connecting rods 404 to move. The movement of the connecting rods 404 drives the connecting seats 403 to move. The connecting seats 403 drive the piston 407 to reciprocate, thus conveying the liquid. An installation nut 406 is threaded onto the installation screw 405. The piston 407 can be installed and fixed by putting the piston 407 on the installation screw 405, putting the sealing gasket on the end of the piston 407, and then screwing the installation nut 406 on the installation screw 405, which facilitates the installation and removal of the piston 407.

[0026] During operation, the sleeve 202 is fitted onto the connecting pipe 201, and the locking block 209 is inserted into the limiting groove 204. After the sleeve 202 is fully fitted onto the connecting pipe 201, the locking block 209 moves to the joint between the limiting groove 204 and the locking groove 205. Then, the button 214 is pressed, and the button 214 moves to push the lever 212 to rotate. The rotation of the lever 212 pushes the movable block 210 to move, and the movement of the movable block 210 drives the pin 211 to move, retracting the pin 211 into the locking block 209. Then, the handle 2 is turned. 08. Rotate the locking block 209 into the slot 205. The locking block 209 moves along the guide block 206. The movement of the locking block 209 causes the sleeve 202 to move closer to the pump body 1, pressing the sealing ring 203. After the locking block 209 moves onto the locking block 207, release the button 214. The return spring 215 inserts the pin 211 into the locking block 207 to lock it, quickly connecting the pipe 3 to the pump body 1. This eliminates the need to use tools to disassemble and install multiple bolts and nuts, effectively improving the convenience of installation and disassembly.
