Description

Technical Field

[0001] The utility model relates to the technical field of water outlet joints, in particular to a water outlet joint for a high-pressure plunger pump. Background Art

[0002] A high-pressure plunger pump is a mechanical pump used to transport liquids. It uses the back-and-forth movement of the plunger in the cylinder to generate high pressure and push the liquid out of the pump body. This type of pump is usually designed for applications that require high pressure, such as pressure testing in the industrial field, water pressure boosting in hydraulic engineering, and liquid transportation in chemical processes. High-pressure plunger pumps usually have the characteristics of high reliability, strong durability, and stable output pressure, so they are widely used in some occasions that require high-pressure transportation.

[0003] At present, the water outlet pipe of the high-pressure plunger pump is usually connected to the external water pipe by threaded connection. It needs to be rotated repeatedly during operation, and specific tools such as wrenches are also needed, which makes the operation cumbersome and the connection efficiency low, especially in the working environment that requires frequent disassembly and connection of the external water pipe. In addition, the high-pressure plunger pump will vibrate during operation, which may cause the threaded connection to loosen and leak. Utility Model Content

[0004] The utility model aims to provide a high-pressure plunger pump water outlet joint which can be quickly connected to and disassembled from an external water pipe and has good connection stability.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A high-pressure plunger pump water outlet joint comprises a water outlet pipe and a joint, wherein a conical end is arranged at the end of the water outlet pipe, a trumpet-shaped end is arranged at the end of the joint, and the trumpet-shaped end is matched with the conical end, a first sealing gasket is arranged on the outer surface of the conical end, mounting blocks are installed on both sides of the outer surface of the water outlet pipe, a handle is hingedly installed at the end of the mounting block, a pull rod is movably installed on the handle, a fixed block is installed on the outer surface of the trumpet-shaped end, a slot is provided on the side of the fixed block facing away from the mounting block, and the pull rod is matched with the slot.

[0007] It can be seen that by pushing the handle to drive the pull rod to tighten the fixing block, the joint can be driven to be tightly and firmly connected to the water outlet pipe. When the handle is pulled up, the pull rod can be separated from the slot, thereby achieving the purpose of quick connection and disassembly. In addition, due to the structural characteristics of the tapered end and the trumpet-shaped end, a tighter connection can be provided. The contact area between the two is large, so that the first sealing gasket can provide a better sealing effect and reduce the risk of leakage.

[0008] Furthermore, a shaft shoulder is arranged on the outer surface of the water outlet pipe, and a second sealing gasket is arranged on the side of the shaft shoulder facing the trumpet-shaped end head.

[0009] When the water outlet pipe is connected to the joint, the end of the trumpet-shaped terminal is pressed against the second sealing gasket, thereby achieving a secondary sealing effect and further reducing the risk of leakage.

[0010] Furthermore, semicircular ring plates are installed on the opposite surfaces of the two handles, and the semicircular ring plates are adapted to the water outlet pipe. A first side block and two second side blocks are respectively installed on both ends of the two semicircular ring plates. A connecting groove is provided on the side of the first side block facing the second side block, and an installation groove is provided on the side of the second side block facing the first side block. Two sliding rods are connected between the inner walls on both sides of the installation groove, and a hook rod is slidably installed on the two sliding rods. A spring is sleeved on the outer surface of the sliding rod, and the two ends of the spring are respectively abutted against the hook rod and the inner wall of the installation groove.

[0011] When the two handles are pushed to a horizontal state, the handles drive the semicircular ring sleeve to be sleeved on the outer surface of the water outlet pipe. During this process, as the first side block and the second side block gradually approach each other, the inclined inner wall on the lower side of the connecting groove and the inclined surface on the upper end of the hook rod contact and squeeze each other, thereby driving the hook rod to move sideways and compress the spring. When the inclined inner wall of the connecting groove is separated from the inclined surface of the hook rod, the compressed spring releases the elastic force, thereby pushing the hook rod to move, so that the hook rod is hooked on the inside of the semicircular ring sleeve, and the two semicircular ring sleeves are connected together. Therefore, during the use of the high-pressure plunger pump, vibration or accidental touch by others can be avoided, which may cause the handle to be pulled up and cause the connection between the water outlet pipe and the joint to loosen and leak, thereby improving the reliability of the connection.

[0012] Furthermore, a push rod is connected to a side of the hook rod facing away from the spring, and an end of the push rod passes through the outer side of the second side block and is installed with a push block.

[0013] When the joint needs to be disassembled, the push block can be pushed inward to drive the push rod to move, and the push rod pushes the hook rod to cancel the hooking state with the connecting groove, and then the handle can be pulled up to realize the rapid disassembly of the joint.

[0014] Furthermore, a finger ring is installed on the outer surface of the handle.

[0015] The finger ring is provided to facilitate the removal of the joint by pulling up the handle.

[0016] Furthermore, the outer surface of the trumpet-shaped end is coaxially arrayed with four first protrusions, the outer surface of the shoulder is coaxially arrayed with four second protrusions, the second protrusions are provided with positioning holes, the outer surface of the first protrusion is connected with a positioning rod, and the positioning rod is adapted to the positioning hole.

[0017] When the joint is connected to the water outlet pipe, the positioning rod can be aligned with the positioning hole and inserted, thereby improving the coaxiality of the joint and the water outlet pipe when connected, thereby ensuring that the first sealing gasket is evenly stressed and improving the sealing effect.

DETAILED DESCRIPTION

[0025] The utility model is described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-6 As shown, a high-pressure plunger pump water outlet joint comprises a water outlet pipe 100 and a joint 101, the end of the water outlet pipe 100 is provided with a conical end cap 102, the end of the joint 101 is provided with a trumpet-shaped end cap 103, and the trumpet-shaped end cap 103 is adapted to the conical end cap 102, the outer surface of the conical end cap 102 is provided with a first sealing gasket 104, mounting blocks 105 are installed on both sides of the outer surface of the water outlet pipe 100, a handle 106 is hingedly installed at the end of the mounting block 105, a pull rod 107 is movably installed on the handle 106, a fixing block 108 is installed on the outer surface of the trumpet-shaped end cap 103, a slot 109 is provided on the side of the fixing block 108 facing away from the mounting block 105, and the pull rod 107 is adapted to the slot 109.

[0027] When it is necessary to connect the connector 101 to the water outlet pipe 100, first put the trumpet-shaped end 103 on the outside of the tapered end 102, then hook the pull rod 107 on the slot 109, and then push the handle 106 to a horizontal state. At this time, the pull rod 107 can pull the connector 101 to be tightly and firmly connected to the water outlet pipe 100, and the first sealing gasket 104 is squeezed by the inner wall of the trumpet-shaped end 103, so as to play a sealing role. When it is necessary to disassemble the connector 101, the handle 106 can be pulled up, and then the pull rod 107 can be taken out from the inside of the slot 109, and then the connector 101 can be directly removed, thereby achieving the purpose of quick disassembly.

[0028] Specifically, a shoulder 200 is provided on the outer surface of the water outlet pipe 100, and a second sealing gasket 201 is provided on the side of the shoulder 200 facing the trumpet-shaped end 103. When the water outlet pipe 100 is connected to the joint 101, the end of the trumpet-shaped end 103 is pressed against the second sealing gasket 201, thereby achieving a secondary sealing effect and further reducing the risk of leakage.

[0029] Specifically, semicircular ring sleeves 300 are installed on the opposite surfaces of the two handles 106, and the semicircular ring sleeves 300 are adapted to the water outlet pipe 100, and the two ends of the two semicircular ring sleeves 300 are respectively installed with a first side block 301 and two second side blocks 302, a connecting groove 303 is provided on the side of the first side block 301 facing the second side block 302, and a mounting groove 304 is provided on the side of the second side block 302 facing the first side block 301, and two sliding rods 305 are connected between the inner walls of the two sides of the mounting groove 304, and a hook rod 306 is slidably installed on the two sliding rods 305. The outer surface of the sliding rod 305 is sleeved with a spring 307, and the two ends of the spring 307 are respectively abutted against the hook rod 306 and the inner wall of the mounting groove 304. When the two handles 106 are pushed to a horizontal state, the handles 106 drive the semicircular ring sleeves 301 to move. The annular sleeve 300 is sleeved on the outer surface of the water outlet pipe 100. During this process, as the first side block 301 and the second side block 302 gradually approach each other, the inclined inner wall of the lower side of the connecting groove 303 and the inclined surface of the upper end of the hook rod 306 contact and squeeze each other, thereby driving the hook rod 306 to move sideways and compress the spring 307. When the inclined inner wall of the connecting groove 303 is separated from the inclined surface of the hook rod 306, the compressed spring 307 releases its elastic force, thereby pushing the hook rod 306 to move, so that the hook rod 306 is hooked inside the semicircular annular sleeve 300, connecting the two semicircular annular sleeves 300 together. Therefore, during the use of the high-pressure plunger pump, the vibration or accidental touch by others can be avoided, causing the handle 106 to be pulled up and causing the connection between the water outlet pipe 100 and the joint 101 to loosen and leak, thereby improving the reliability of the connection.

[0030] Specifically, a push rod 308 is connected to the side of the hook rod 306 facing away from the spring 307. The end of the push rod 308 passes through the outer side of the second side block 302 and is installed with a push block 309. When the connector 101 needs to be disassembled, the push block 309 can be pushed inward to drive the push rod 308 to move. The push rod 308 pushes the hook rod 306 to cancel the hooking state with the connecting groove 303, and then the handle 106 can be pulled up to realize the quick disassembly of the connector 101.

[0031] Specifically, a finger ring 400 is installed on the outer surface of the handle 106 . The finger ring 400 makes it easy to pull up the handle 106 and disassemble the connector 101 .

[0032] Specifically, the outer surface of the trumpet-shaped end 103 is coaxially arrayed with four first protrusions 500, and the outer surface of the shoulder 200 is coaxially arrayed with four second protrusions 501. The second protrusion 501 is provided with a positioning hole 502. The outer surface of the first protrusion 500 is connected with a positioning rod 503, and the positioning rod 503 is adapted to the positioning hole 502. When the joint 101 is connected to the water outlet pipe 100, the positioning rod 503 can be aligned with the positioning hole 502 and inserted, thereby improving the coaxiality of the joint 101 when connected to the water outlet pipe 100, thereby ensuring that the first sealing gasket 104 is evenly stressed and the sealing effect is improved.
