Description

Technical Field

[0001] The utility model relates to the technical field of pipeline interfaces, in particular to a filter pipeline interface. Background Art

[0002] The filter pipeline interface is an inevitable part in assembly and maintenance. For the current filter common pipeline interfaces for the screw-on iron can assembly, most are aluminum seats matched with hinged bolts; for composite filters, there are often plastic interfaces welded to plastic filter seats, and there are also plastic joints and filter seats axially snap-fitted.

[0003] The current connection of the filter pipeline needs to be used through the connection of flanges and bolts. When installing, the bolts need to be locked one by one, which is more cumbersome during installation. At the same time, the use of bolts requires more materials, increasing costs. At the same time, after the filter pipeline fixed by the flange is fixed by bolts, the two filter pipelines cannot rotate relative to any angle, reducing the product application range. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a filter pipeline interface to solve the problems of cumbersome butt joint and inconvenient use of the filter pipeline.

[0005] Based on the technical problems existing in the background art, the utility model provides a filter pipeline interface, including a quick plug and a sleeve. The quick plug is provided with an annular pin slot, and the sleeve is provided with two parallel slots. When the quick plug is inserted into the sleeve, the annular pin slot is aligned with the slots. A U-shaped clamp is slidably clamped in the slots, and the U-shaped clamp passes through the annular pin slot to limit the quick plug.

[0006] Preferably, one end of the quick plug facing the sleeve is connected with a plurality of reinforcing beams.

[0007] Preferably, the quick plug is also provided with an annular sealing groove, and the annular sealing groove is located between the reinforcing beam and the annular pin slot.

[0008] Preferably, a sealing ring is sleeved on the annular sealing groove. After the quick plug is docked with the sleeve, the sealing ring can seal the gap between the quick plug and the inner wall of the sleeve.

[0009] Preferably, after the quick plug is docked with the sleeve, the annular sealing groove is located between the reinforcing beam and the slots.

[0010] Preferably, the end of the U-shaped clamp is provided with a hook, and a boss is grafted on the slot. The U-shaped clamp passes through the slot and is clamped with the boss through the hook.

[0011] Preferably, one end of the quick plug far from the annular pin slot is communicated with a standard interface.

[0012] Compared with the prior art, a filter pipe interface proposed by the present utility model adopts the above technical solution and achieves the following technical effects:

[0013] In the present utility model, a simple connection and installation can be achieved between the quick plug and the pipe sleeve, enabling quick docking, reducing the complexity of installation, and improving convenience during maintenance and use; the quick plug in the present utility model can rotate 360 degrees relative to the pipe sleeve to achieve multi-angle usage scenarios.

[0021] Embodiment

[0022] Please refer to Figures 1 to 4 , the present utility model provides a filter pipe interface, which includes a quick plug 1 and a pipe sleeve 2. An annular pin slot 11 is provided on the quick plug 1, and two parallel notches 21 are provided on the pipe sleeve 2. When the quick plug 1 is inserted into the pipe sleeve 2, the annular pin slot 11 is aligned with the notch 21 in the vertical direction. A U-shaped clamp 3 is slidably clamped in the notch 21. The U-shaped clamp 3 passes through the notch 21 and also slides through the annular pin slot 11. At this time, when the quick plug 1 is pulled out in a direction away from the pipe sleeve 2, the annular pin slot 11 will be limited by the U-shaped clamp 3. When the U-shaped clamp 3 moves in the direction of pulling out the quick plug 1, it will be limited by the notch 21. At this time, the quick plug 1 will be restricted within the pipe sleeve 2, and the quick plug 1 can rotate within the pipe sleeve 2.

[0023] In a specific embodiment, referring to Figure 1 , a plurality of reinforcing beams 12 are connected to the end of the quick plug 1 facing the pipe sleeve 2. In this application, the reinforcing beams 12 on the quick plug 1 will support the outer wall of the pipe sleeve 2. The end of the reinforcing beam 12 away from the quick plug 1 will have a maximum diameter range, and the maximum diameter range is slightly larger than the inner diameter of the pipe sleeve 2. During installation, the reinforcing beam 12 is elastic and is bent and inserted into the pipe sleeve 2. The reinforcing beam 12 will also support and hang on the inner wall of the pipe sleeve 2 within the pipe sleeve 2, playing a role in aligning the quick plug 1 and making the quick plug 1 coaxial with the pipe sleeve 2.

[0024] In a specific embodiment, referring to Figure 1 , an annular sealing groove 13 is also provided on the quick plug 1. The annular sealing groove 13 is located between the reinforcing beam 12 and the annular pin slot 11; a sealing ring 4 is sleeved on the annular sealing groove 13. After the quick plug 1 is docked with the pipe sleeve 2, the sealing ring 4 can seal the gap between the quick plug 1 and the inner wall of the pipe sleeve 2. After the quick plug 1 is docked with the pipe sleeve 2, at this time, the sealing ring 4 can block the gap between the two, realizing the connection between the quick plug 1 and the pipe sleeve 2.

[0025] In a specific embodiment, referring to Figure 1 , after the quick plug 1 is docked with the pipe sleeve 2, the annular sealing groove 13 is located between the reinforcing beam 12 and the notch 21. After the sealing ring 4 is installed, it is necessary to prevent liquid leakage from the notch 21. Therefore, the sealing ring 4 is installed between the reinforcing beam 12 and the notch 21 to seal in advance.

[0026] In a specific embodiment, referring to Figure 1 , a hook 31 is provided at the end of the U-shaped clamp 3, and a boss 22 is grafted on the notch 21. At this time, a ring groove is formed between the boss 22 and the notch 21. The U-shaped clamp 3 passes through the ring groove to clamp the quick plug 1. At this time, the hook 31 at the end of the U-shaped clamp 3 will hang on the boss 22 to prevent the U-shaped clamp 3 from detaching. The U-shaped clamp 3 passes through the notch 21 and is clamped by the hook 31 and the boss 22.

[0027] In a specific embodiment, with reference to Figure 1 , one end of the quick plug 1 away from the annular pin slot 11 is communicated with a standard interface 14, and the standard interface 14 is used to connect a pipeline.

[0028] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
