Abstract
The utility model relates to a gas connection bolt, including head and pole portion, coaxially between head and the pole portion be provided with external tracheal mounting hole, be provided with automatic fixed tracheal installation component on the installation pore wall, installation component includes installation cavity, locating piece and reset spring, and the installation cavity radially sets up in the installation pore wall along pole portion, and the locating piece lies in the installation cavity can follow the installation cavity and slide, and the reset spring pressure is located and is restored to the throne the locating piece to the mounting hole between installation cavity and the locating piece. When the scheme is adopted, the utility model provides an automatic gas connection bolt who carries out fixed mounting to the trachea.
Description
Technical field
The utility model is specifically related to one and connects gas bolt.
Background technology
Bolt is the fixture that fitted bolt hole is fixed the parts that passed by bolt, due to simple in structure, easy for installation, is applied to various industries.
Traditional bolt is made up of the bar portion of head and fixed length, connecing gas bolt is between head and bar portion, to be coaxially arranged with the installing hole that inserts tracheae, traditional tracheae also needs other fixtures after insertion connects gas bolt, similar steel wire is fixed, and steel wire causes the deformation of tracheae even to leak gas in the course of time.
Summary of the invention
The deficiency existing for prior art, the purpose of this utility model be to provide a kind of automatically tracheae is fixed to installation connect gas bolt.
For achieving the above object, the utility model provides following technical scheme: comprise head and bar portion, between described head and bar portion, be coaxially arranged with the installing hole of external tracheae, it is characterized in that: the installation component that is provided with automatically fixing tracheae on described installation hole wall, described installation component comprises installation cavity, locating piece and back-moving spring, described installation cavity is radially arranged at installation hole wall along bar portion, described locating piece is positioned at installation cavity also can be along installation cavity slippage, described back-moving spring is installed with between installation cavity and locating piece locating piece is resetted to installing hole.
By adopting technique scheme, locating piece is set, when trachea inserts outside, realize fixed installation with the laminating of its outer peripheral face, avoid adopting other fixtures to cause damage to external pipe, convenient operation and prolongation external pipe service life.
The utility model is further set to: described locating piece comprises towards the end of installing hole and is provided with lead-in chamfered, when the trachea extruding outside of this lead-in chamfered, guides locating piece to shrink to installation cavity.
By adopting technique scheme, lead-in chamfered is set, while inserting external tracheae, locating piece shrinks automatically, improves simple operation.
The utility model is further set to: on described installation hole wall, be provided with two groups of installation components, two groups of described installation components are oppositely arranged about installing hole central shaft.
By adopting technique scheme, installation component quantity can be many groups, preferably two groups, ensures to install stability when simplifying difficulty of processing.
The utility model is further set to: in described lead-in chamfered, be coated with elastic compression layer.
By adopting technique scheme, elastic compression layer reduces between locating piece and external pipe and weares and teares, and more adaptive with external pipe outer peripheral face, further extends external tracheae service life.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
