Description

Technical Field

[0001] This utility model relates to the field of three-cylinder plunger pump technology, specifically to a tool-free disassembly end cap for a three-cylinder plunger pump. Background Technology

[0002] A three-cylinder plunger pump is a positive displacement pump that relies on the alternating reciprocating motion of three plungers to achieve liquid intake and discharge. It is widely used in high-pressure cleaning, agricultural irrigation, petrochemicals, municipal engineering, and other applications requiring high-pressure liquid transport. Its core feature is that the coordinated work of the three plungers reduces flow fluctuations and improves the stability of output pressure. The end cap of the three-cylinder plunger pump is a key component installed at the end of the pump body.

[0003] In existing technologies, the end caps of three-cylinder plunger pumps are mostly installed and fixed using bolts and other connecting parts. The installation process requires aligning the holes and then using auxiliary tools, which is cumbersome and inconvenient, especially since disassembly and assembly are impossible without the necessary tools. Therefore, we propose a tool-free, removable end cap for three-cylinder plunger pumps. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a tool-free disassembly end cap for a three-cylinder plunger pump. This solves the problem that the end caps of three-cylinder plunger pumps are mostly installed and fixed by bolts and other connecting parts. During the installation process, the holes need to be aligned and then auxiliary tools are needed to install and fix them. The operation steps are relatively cumbersome, and the disassembly and assembly operations cannot be performed if the tools are not available.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The tool-free removable end cap for a three-cylinder plunger pump includes a mounting ring. A rotating ring is rotatably connected to the inner wall of the mounting ring.

An insert rod is slidably connected inside the connecting rod. A fixing block is fixedly connected to the outer side of the mounting ring. Slots that mate with the insert rods are equidistantly formed inside the fixing block. The plunger pump end cap can be locked in place by moving the locking block into the locking groove.

[0007] Preferably, the inner wall of the mounting ring is fixedly connected with limit rods at equal intervals, and a connecting block is fixedly connected to one side of the locking block. The connecting block is slidably connected to the limit rods. The movement of the locking block can be limited by the setting of the limit rods and the connecting block.

[0008] Preferably, the connecting rod is fitted against the inner wall of the mounting ring, and the connection between the connecting rod and the inner wall of the mounting ring can limit the movement of the connecting rod.

[0021] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 7 This utility model provides a technical solution:

[0023] The tool-free removable end cap for a three-cylinder plunger pump includes a mounting ring 1. A rotating ring 9 is rotatably connected to the inner wall of the mounting ring 1. A protrusion 10 is fixedly connected at equal intervals to one side of the rotating ring 9. A locking block 6 is slidably connected at equal intervals inside the mounting ring 1. A connecting bracket 7, which mates with the protrusion 10, is fixedly connected to one side of the locking block 6. A plunger pump end cap 2 is located inside the mounting ring 1. Locking grooves 17, which mate with the locking block 6, are equidistantly opened inside the plunger pump end cap 2. A connecting rod 4 is fixedly connected to the outer side of the rotating ring 9. A sliding insert rod 14 is slidably connected inside the connecting rod 4. A fixing block 3 is fixedly connected to the outer side of the mounting ring 1. The fixing block 3 has equidistantly opened... The device is equipped with a slot 11 for use with the insertion rod 14. The connecting rod 4 drives the protrusion 10 to rotate via the rotating ring 9, causing the protrusion 10 to press and drive the connecting frame 7 to move. The connecting frame 7 drives the locking block 6 to slide. By moving the locking block 6 into the locking groove 17, the position of the plunger pump end cover 2 can be locked. By moving the insertion rod 14 into the corresponding slot 11, the position of the connecting rod 4 can be locked, thus completing the installation of the plunger pump end cover 2. When it needs to be disassembled, the connecting rod 4 can be rotated in the opposite direction. The operation is convenient and no auxiliary tools are needed during the disassembly and assembly process. The operation steps are simpler and the disassembly and assembly efficiency is higher.

[0024] Furthermore, the inner wall of the mounting ring 1 is fixedly connected with limit rods 8 at equal intervals, and a connecting block 5 is fixedly connected to one side of the locking block 6. The connecting block 5 is slidably connected to the limit rods 8. The movement of the locking block 6 can be limited by the setting of the limit rods 8 and the connecting block 5 to prevent displacement.

[0025] Furthermore, the connecting rod 4 is in contact with the inner wall of the mounting ring 1. By the contact between the connecting rod 4 and the inner wall of the mounting ring 1, the connecting rod 4 can be limited to prevent it from shifting during movement.

[0026] Furthermore, a slider 16 is slidably connected inside the connecting rod 4, and the insertion rod 14 is fixedly connected to the slider 16. A spring 15 is provided at equal distance between the slider 16 and the connecting rod 4. The spring 15 can drive the slider 16 to move and reset, and the slider 16 can drive the insertion rod 14 to move.

[0027] Furthermore, the slider 16 is in contact with the inner wall of the connecting rod 4. By the contact between the slider 16 and the inner wall of the connecting rod 4, the movement of the slider 16 can be limited, so that the slider 16 slides along the inner wall of the connecting rod 4 to prevent deviation.

[0028] Furthermore, a push rod 13 is fixedly connected to one side of the slider 16, and a push block 12 is fixedly connected to the end of the push rod 13 away from the slider 16. The push block 12 drives the push rod 13 to move, and the push rod 13 drives the slider 16 to move.

[0029] Working principle:

[0030] In use, the mounting ring 1 is installed on the end cover of the three-cylinder plunger pump using bolts. The plunger pump end cover 2 is pushed into the mounting ring 1. After pushing, the push block 12 is pushed. The push block 12 drives the slider 16 to slide along the inner wall of the connecting rod 4 via the push rod 13. The spring 15 is compressed, and the slider 16 drives the insertion rod 14 to move and disengage from the slot 11, allowing the connecting rod 4 to rotate. The connecting rod 4 drives the protrusion 10 to rotate via the rotating ring 9, causing the protrusion 10 to press and drive the connecting frame 7 to move. The connecting frame 7 drives the locking block 6 to slide, which is achieved through the limit rod 8 and the connecting block 5. The locking block 6 can be positioned to limit its movement and prevent offset. By moving the locking block 6 into the locking groove 17, the position of the plunger pump end cover 2 can be locked. When the push block 12 is released, the spring 15 will move and reset the slider 16 due to its elasticity. The slider 16 will move the insertion rod 14 into the corresponding slot 11, thereby locking the position of the connecting rod 4 and completing the installation of the plunger pump end cover 2. When it needs to be disassembled, simply rotate the connecting rod 4 in the opposite direction. The operation is convenient and does not require auxiliary tools during the disassembly and assembly process. The operation steps are simpler and the disassembly and assembly efficiency is higher.
