Description

The flexible pipe structure of dust catcher

Technical field

The utility model relates to cleaner technology fields, and in particular to a kind of flexible pipe structure of dust catcher.

Background technique

The inner tube and outer tube of the telescoping tube of existing dust catcher are generally sealed by sealing ring, and sealing ring during installation, needs Sealing ring is generated into biggish deformation and gets into placing groove, this assembling process easily causes sealing ring to damage, and influences inner tube and outer The airtight quality of pipe.

Utility model content

The purpose of this utility model is to provide a kind of flexible pipe structure of dust catcher, it to be used for sealed inner tube and outer tube Sealing ring is not damaged in assembling, the quality of the sealing ring after guaranteeing assembling.

To achieve the above object, the utility model provides the following technical solutions：

A kind of flexible pipe structure of dust catcher, including inner and outer tubes, inner tube are inserted in outer tube, and inner tube is matched with outer tube sliding It closes, the end of outer tube wall is equipped with annular putting groove, and the sealing ring of sealed outer pipe and inner tube, sealing are laid in annular putting groove Circle includes the first half-turn and the second half-turn, and the both ends of the first half-turn are respectively equipped with seal insert, and the both ends of the second half-turn are set respectively There is sealing cutting, sealing cutting is inserted into seal insert respectively.

Preferably, sealing cutting interference is inserted into seal insert.

Preferably, the silica gel strip that cutting includes steel wire and is wrapped on the outside of steel wire is sealed.

The working principle of the utility model is：When assembling sealing ring, the first half-turn is first received in putting groove, then by second Half-turn is received in putting groove, and the sealing cutting of the second half-turn is inserted into the seal insert of the first half-turn, the peace of sealing ring is completed It puts；Entire installation course, sealing ring are not present big deformation, the quality of sealing ring have been effectively ensured.It seals cutting and uses steel wire With the setting for the silica gel strip being wrapped on the outside of steel wire, steel wire can be inserted into the first half-turn, facilitate the company of the first half-turn and the second half-turn It connects, while in turn ensuring sealing effect.

The beneficial effects of the utility model are：It is used for sealed inner tube and the sealing ring of outer tube not will receive damage in assembling Wound, the quality of the sealing ring after guaranteeing assembling.

Detailed description of the invention

Fig. 1 is the schematic diagram of the utility model.

Specific embodiment

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is further described.Implement below Example is only used for clearly illustrating the technical solution of the utility model, and cannot be used as a limitation the protection model of limitation the utility model It encloses.

The utility model specific implementation technical solution be：

As shown in Figure 1,

A kind of flexible pipe structure of dust catcher, including inner and outer tubes, inner tube are inserted in outer tube, and inner tube is matched with outer tube sliding It closes, the end of outer tube wall is equipped with annular putting groove, and the sealing ring of sealed outer pipe and inner tube, sealing are laid in annular putting groove Circle includes the first half-turn 1 and the second half-turn 2, and the both ends of the first half-turn 1 are respectively equipped with seal insert, the both ends point of the second half-turn 2 Cutting 3 She You not be sealed, sealing cutting 3 is inserted into seal insert respectively.

Sealing 3 interference of cutting is inserted into seal insert.

Sealing cutting 3 includes steel wire and the silica gel strip being wrapped on the outside of steel wire.

The working principle of the utility model is：When assembling sealing ring, the first half-turn 1 is first received in putting groove, then by the Two half-turns 2 are received in putting groove, and the sealing cutting 3 of the second half-turn 2 is inserted into the seal insert of the first half-turn 1, sealing is completed The placement of circle；Entire installation course, sealing ring are not present big deformation, the quality of sealing ring have been effectively ensured.Sealing cutting 3 is adopted With the setting of steel wire and the silica gel strip being wrapped on the outside of steel wire, steel wire can be inserted into the first half-turn 1, facilitate the first half-turn 1 and second The connection of half-turn 2, while in turn ensuring sealing effect.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without deviating from the technical principle of the utility model, several improvements and modifications can also be made, these change It also should be regarded as the protection scope of the utility model into retouching.
