Abstract
The utility model relates to a connector in a pipeline connection device, which comprises a tubular mounting head, and a hose connector; one end of the tubular mounting head is locked with one end of the hose connector by a locking piece; the tubular mounting head is communicated with the inner cavity of the hose connector; and one end surface of the tubular mounting head and one end surface of the hose connector are sealed by a seal ring. Therefore, the structure not only is convenient to be mounted, but also has good seal effect.
Description
Technical field
The utility model relates to assembling pipe joint, particularly a kind of jointing.
Background technique
Gases such as air, oxygen, rock gas or carbon dioxide generally are to charge in machine or the equipment by jointing, jointing of the prior art comprises the tubulose installation head that is connected with machine or equipment, the hose coupling that is connected with flexible pipe, described tubulose installation head is communicated with the inner chamber of hose coupling and locks by locking element, but, described hose coupling is installed an end that cooperates for conical with described tubulose, this taper shape butt and described hollow fixed block form sealing configuration, this structure is not only installed inconvenience, and sealing effect is bad.
The utility model content
The utility model is intended to overcome above-mentioned the deficiencies in the prior art, provides a kind of not only easy for installation, and the jointing of good sealing effect.
A kind of jointing that provides according to the utility model, comprise tubulose installation head, a hose coupling, described tubulose is installed an end of head and an end of hose coupling is locked by locking element, described tubulose is installed head and is communicated with the inner chamber of hose coupling, seals by O-ring seal between a described end end face of described tubulose installation head and the described end end face of described hose coupling.
The utility model also has following additional technical feature:
Described hose coupling end face extension is formed with one section and can stretches into the cylindrical tube of installing in the inner chamber, and this cylindrical tube is inner to communicate with the hose coupling inner chamber, and described O-ring seal cover is arranged at the root of cylindrical tube.
The described end end face of described hose coupling is formed with annular groove around the root of described cylindrical tube, and described O-ring seal partly is embedded in this annular groove.
Described tubulose is installed a neutral position and is provided with a polygonal boss that cooperates with spanner.
Described locking element is a nut, described tubulose is installed a described end and is provided with the outside thread that cooperates with nut one end, the end formed boss that evagination is arranged of a described end of described hose coupling, the other end inner circle wall of described nut inwardly are formed with the internal projecting ring that the boss with described evagination fastens.
According to a kind of jointing that the utility model provides, prior art has following advantage relatively:
Seal by O-ring seal between a described end end face of described tubulose installation head and the described end end face of described hose coupling, and described tubulose is installed a described end end face of head and a described end end face of described hose coupling has formed plane sealing.Therefore, this structure is not only easy for installation, and good sealing effect.
Description of drawings
Embodiment below in conjunction with accompanying drawing provides describes the utility model in detail, wherein:
Fig. 1 is the cross-sectional schematic of integral assembling structure locking state of a kind of preferred embodiment of a kind of jointing of the utility model.
Embodiment
Referring to Fig. 1, a kind of optimal way of a kind of jointing of the utility model is shown, comprise that a tubulose installs 1, one hose coupling 2, described tubulose is installed an end of head and an end of hose coupling is locked by locking element 3, described tubulose is installed the inner chamber 11 of head and hose coupling, 21 communicate, between the described end end face that described tubulose is installed head and the described end end face of described hose coupling by O-ring seal 4 sealings (a described end end face of described tubulose installation 1 and a described end end face of described hose coupling 2 are respectively tubulose installation 1 and hose coupling 2 mutual corresponding end faces); Described hose coupling 2 end faces extension is formed with one section and can stretches into the cylindrical tube of installing in the inner chamber 11 5, this cylindrical tube inner 51 communicates with hose coupling inner chamber 21, described hose coupling 2 described end end faces are formed with annular groove 41 around the root of described cylindrical tube 5, and described O-ring seal 4 parts are embedded in this annular groove.So described tubulose is installed between the described end end face of a described end end face of 1 and described hose coupling 2 and formed plane sealing, described seal ring 4 is the effect of enhancing sealing effect.Therefore, this described tubulose install 1 with hose coupling 2 both are not only simple in structure, and easy for installation, good sealing effect.
Described tubulose is installed 1 neutral position and is provided with a polygonal boss 12 that cooperates with spanner; Described locking element 3 is a nut, described tubulose is installed 1 a described end and is provided with the outside thread that cooperates with nut one end, the end formed boss 6 that evagination is arranged of a described end of described hose coupling 2, the other end inner circle wall of described nut inwardly are formed with the internal projecting ring 61 that the boss 6 with described evagination fastens.Therefore, the boss 6 of described evagination engages mutually with internal projecting ring 61, described nut for the described tubulose of locking install 1 with the usefulness of hose coupling 2.
The foregoing description is only for the usefulness that the utility model is described; and be not to be to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification; therefore all technological schemes that are equal to also should belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
