Abstract

The utility model discloses a connecting device of channels between filter elements of a filter and comprises a pedestal and movable bases, wherein, the movable bases can be connected with the pedestal in a rotatable way and one end of the filter element is sleeved with lower ends of the movable bases; a flow connecting channel which is arranged between two movable bases further comprises an external connecting pipe and an internal pipe; both ends of the external connecting pipe are respectively inserted into lateral through holes of the two movable bases and the internal pipe is sleeved in the external connecting pipe and communicated with the flow channel in the movable bases. The utility model consisting of the internal pipe and the external connecting pipe is connected in a way that the internal pipe is sleeved with the external pipe, which separates the bearing done by the external connecting pipe and the water passing done by the internal pipe; the internal pipe is responsible only for the water passing and can use any water pipes such as a soft pipe or a hard pipe, which effectively avoids the phenomenon of water seepage.

Description

Assembling pipe joint between the filter element

Technical field

The utility model relates to a kind of structure of filter, particularly relates to assembling pipe joint between a kind of filter element.

Background technology

At present, town dweller's drinking water is the running water that does not reach the clean water quality requirement as yet that is provided by the waterworks, directly drinks to impair one's health.For this reason, existing a lot of families uses filter, is used for to carrying out further purified treatment from the water in the water supply pipe, with the degree of purity of increasing water quality.The holder of filter is to be used for fixing the parts that connect filter core.The bore of the filter of commonly using (as shown in Figure 1) filter core 1 ' is bigger, its be external thread bolt connection by oral area 11 ' on holder 2 ', in renew cartridge 1 ' more, need be rotated down filter core 1 like this, just filter core 1 ' can be unloaded.Under the less situation in space, the installation of filter core 1 ', dismounting be difficulty all relatively, and when installing, the limitation because of the space is difficult to the power of using sometimes especially, causes not being connected tight and causing leaking between filter core 1 ' and the base 2 ' easily.So, there have the dealer to design to be a kind of mainly by base 1 " and sliding seat 2 " fixing apparatus for filter (as shown in Figure 2) formed, this fixing apparatus for filter still exists and is socketed in two sliding seat 2 " between siphunculus 3 " in transportation because of vibrations, rock loosening easily defective.In addition,, bear the gravity effect again, seep water easily because siphunculus is both as the usefulness of water stream channel between two sliding seat.

The utility model content

The purpose of this utility model is to provide assembling pipe joint between a kind of new filter element, and this jockey can effectively prevent to be socketed in oozing out of passage current between two sliding seat in transportation.

For achieving the above object, technical solution of the present utility model is:

The utility model is an assembling pipe joint between a kind of filter element, and it comprises base and sliding seat, and sliding seat is rotating to be connected on the base, and an end of filter core is socketed in the sliding seat lower end; Between two sliding seat, be provided with the current interface channel; It also comprises outer connecting pipe and interior pipe described current interface channel; Insert respectively in the cross through hole of two sliding seat at the two ends of outer connecting pipe, and interior pipe box puts in outer connecting pipe, be connected with water stream channel in the sliding seat.

Offer annular slot on the insertion section circumferential surface in the cross through hole of described outer connecting pipe insertion sliding seat; On sliding seat, offer a groove that connects with cross through hole; Described little interior folder can pass the groove of sliding seat and be connected on the annular slot that inserts on the interior outer connecting pipe of sliding seat cross through hole.

After adopting such scheme, the utility model is made up of interior pipe and outer connecting pipe, the mode of promptly utilizing interior pipe box to put outer tube connects, load-bearing and water flowing are separated, and outer connecting pipe is responsible for load-bearing, and interior pipe is responsible for water flowing, because interior pipe only is responsible for water flowing, can use any water pipe,, thereby effectively prevent the generation of infiltration phenomenon as flexible pipe or stereoplasm tube etc.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

The specific embodiment

As shown in Figure 3, the utility model is an assembling pipe joint between a kind of filter element, and it comprises base 1, sliding seat 2, outer connecting pipe 3, interior pipe 4 and little interior folder 5.

Described sliding seat 2 rotating being connected on the base 1, an end of filter core 6 is socketed in sliding seat 2 lower ends; Between two sliding seat 2, be provided with the current interface channel; Described current interface channel is made of outer connecting pipe 3 and interior pipe 4; Insert respectively in the cross through hole of two sliding seat 2 at the two ends of outer connecting pipe 3, and interior pipe 4 is nested with in outer connecting pipe 3, (as Fig. 5, shown in Figure 6) is connected with water stream channel in the sliding seat 2.

Offer annular slot 31 (as shown in Figure 4) on the insertion section circumferential surface in the cross through hole of described outer connecting pipe 3 insertion sliding seat 2; On sliding seat 2, offer a groove 21 that connects with cross through hole; Described little interior folder 5 can pass the groove 21 of sliding seat and be connected on the annular slot 31 that inserts on the interior outer connecting pipe 3 of sliding seat 2 cross through hole, and outer connecting pipe 3 can not deviate from from sliding seat 2.For the sliding seat 2 ' of some mutual plug-ins, also can be without outer connecting pipe, and only use interior pipe 4 ' (as shown in Figure 7).
