Description

Technical Field

[0001] The utility model relates to the technical field of joints, in particular to a detachable joint. Background Art

[0002] A filter element connector refers to a component that connects the filter element to the filter housing, serving to connect, seal, and support the filter element. Publication No. CN213132243U discloses a filter element connector comprising a filter connector and a docking connector. The connector is characterized in that the left end face of the filter connector is connected to the docking connector, a filter element is disposed in the internal cavity of the filter connector, an anti-shake seat is disposed on the left end of the filter element and is engaged with the interior of a card interface disposed within the filter connector, the front and rear ends of the filter element are both configured as tapered liquid guide ports, and a sealing ring is disposed at the docking end between the filter connector and the docking connector. The utility model provides a filter element connector in which the filter element is effectively secured by a two-end clamping method. At the same time, tapered liquid guide surfaces are disposed on both sides of the filter element, effectively improving the efficiency of feeding and discharging the filter element. However, disassembly of the connector requires considerable effort from the operator to pull the filter connector and docking connector apart, making it difficult for operators with less strength to disassemble. This connector still has shortcomings and needs improvement. Utility Model Content

[0005] Preferably, one end of the spring is fixedly connected to the inner surface of the mounting hole, and the other end of the spring is fixedly connected to the elastic pin. Here, the fixed connection improves the use effect of the spring.

[0006] Preferably, the filter connector and the butt joint are connected by sliding, thereby improving the disassembly efficiency between the filter connector and the butt joint.

[0007] Preferably, the elastic pin is slidably connected to the mounting hole, and the elastic pin is slidably connected to the limiting hole. Here, the use effect of the elastic pin is improved by the sliding connection.

[0008] Preferably, the filter connector has a first groove formed on one end near the docking connector, a second groove formed on one end near the docking connector, a first rubber ring fixedly mounted on one end near the filter connector, and a second rubber ring fixedly mounted on one end near the filter connector. Here, by docking the filter connector and the docking connector, the first rubber ring snaps into the first groove, and the second rubber ring snaps into the second groove during docking, thereby improving the sealing effect between the filter connector and the docking connector and effectively preventing liquid or gas leakage.

[0009] Preferably, the groove 1 is slidably connected to the rubber ring 1, and the groove 2 is slidably connected to the rubber ring 2. Here, the sliding connection improves the clamping efficiency of the rubber ring 1 and the rubber ring 2.

In the utility model, by setting up structures such as mounting holes, springs, spring pins, L-frames and limit holes, by pressing two sets of spring pins at the same time, the spring pins squeeze the springs and retract into the interior of the mounting holes. After retracting a certain distance, the spring pins will move away from the limit holes. After moving away, the filter joint and the docking joint can be separated and disassembled. This structure only requires very little force to disassemble the filter joint and the docking joint, thereby effectively avoiding the difficulty of operators with less strength to disassemble the filter joint and the docking joint, and facilitating the operation of the operators.

[0012] 2. In the utility model, by providing structures such as groove one, groove two, rubber ring one and rubber ring two, the filter joint and the docking joint are docked. During the docking process, the rubber ring one will be stuck in the groove one, and the rubber ring two will be stuck in the groove two, thereby improving the sealing effect between the filter joint and the docking joint, and effectively preventing liquid or gas leakage.

An L-shaped frame 6 is symmetrically fixedly mounted on the outer wall of the end of the filter joint 1 near the butt joint 2. A limit hole 7 is formed through the outer side of the L-shaped frame 6. A mounting hole 3 is symmetrically formed on the outer wall of the end of the butt joint 2 near the filter joint 1. A spring 4 is mounted inside the mounting hole 3. A spring pin 5 is mounted on the end of the spring 4 away from the mounting hole 3. By providing the mounting hole 3, the spring 4, the spring pin 5, the L-shaped frame 6, and the limit hole 7, the two sets of spring pins 5 can be pressed simultaneously, so that the spring pins 5 squeeze the spring 4 and retract into the mounting hole 3. After retracting a certain distance, the spring pins 5 will move away from the limit hole 7. After moving away, the filter joint 1 and the butt joint 2 can be separated and disassembled. This structure only requires a small amount of force to disassemble the filter joint 1 and the butt joint 2, thereby effectively preventing operators with less strength from having difficulty in disassembling the filter joint 1 and the butt joint 2, and facilitating the operation.

[0023] See also Figure 1-3 One end of the spring 4 is fixedly connected to the inner surface of the mounting hole 3, and the other end of the spring 4 is fixedly connected to the elastic pin 5. The fixed connection improves the use effect of the spring 4. The filter joint 1 and the docking joint 2 are slidingly connected. The disassembly efficiency between the filter joint 1 and the docking joint 2 is improved through the sliding connection.

A rubber ring 10 is fixedly installed at one end of the butt joint 2 close to the filter joint 1, and a rubber ring 2 is fixedly installed at one end of the butt joint 2 close to the filter joint 1. By docking the filter joint 1 with the butt joint 2, the rubber ring 10 will be stuck into the groove 18, and the rubber ring 211 will be stuck into the groove 29 during the docking process, thereby improving the sealing effect between the filter joint 1 and the butt joint 2, effectively preventing liquid or gas leakage. The groove 18 and the rubber ring 10 are slidingly connected, and the groove 29 and the rubber ring 211 are slidingly connected, and the sliding connection improves the clamping efficiency of the rubber ring 10 and the rubber ring 211.

[0026] Working principle: When disassembling, first press the two sets of spring pins 5 simultaneously, so that the spring pins 5 squeeze the spring 4 and retract into the interior of the mounting hole 3. After retracting a certain distance, the spring pins 5 will move away from the limit hole 7. After moving away, the filter connector 1 and the docking connector 2 can be separated and disassembled, thereby effectively preventing operators with less strength from having difficulty in disassembling the filter connector 1 and the docking connector 2. When docking the filter connector 1 and the docking connector 2, the rubber ring 10 will be stuck in the groove 1 8, and the rubber ring 2 will be stuck in the groove 2 9, thereby improving the sealing effect between the filter connector 1 and the docking connector 2, effectively preventing liquid or gas leakage.
