The purpose of this utility model is to provide a kind of metal joint, its structure is simple, easy for installation, good airproof performance, stability is high, and the setting of lubrication inner chamber can lubricated metal joint and connection metal pipe thus avoid metal joint or connection metal pipe to break or the situation of breaking occurs.
In order to achieve the above object, the technical solution of the utility model is:
A kind of metal joint, comprise joint body, connecting through hole is offered in described joint body, described joint body comprises the first connecting head, the second connecting head, described first connecting head one end is connected with the second connecting head, the described first connecting head the other end is connected with positioning block, and described second connecting head offers outside thread; Described first connecting head sidewall offers respectively the first installation groove, second and groove is installed, the first lubrication inner chamber is offered in described first installation groove, described first lubrication inner chamber is communicated with connecting through hole by the first lubrication runner to be installed, offer the second lubrication inner chamber in described second installation groove, described second lubrication inner chamber is communicated with connecting through hole by the second lubrication runner to be installed.
The sidewall of described first installation groove offers the first sealed groove, in described first sealed groove, the first seal ring is installed; The sidewall of described second installation groove offers the second sealed groove, in described second sealed groove, the second seal ring is installed.
First connecting head sidewall of described first connecting head and the second connecting head connecting place is provided with scuff-resistant coating.
Described first connecting head is equidistantly provided with 8 positioning blocks.
Described positioning block both sides are all provided with sealing layer.
Described positioning block offers lubrication groove.
Described positioning block is fan-shaped positioning block.
Described second depth of groove of installing groove is greater than the depth of groove of the first installation groove.
The beneficial effects of the utility model are: a kind of metal joint, its structure is simple, easy for installation, good airproof performance, stability is high, and the setting of lubrication inner chamber can lubricated metal joint and connection metal pipe thus avoid metal joint or connection metal pipe to break or the situation of breaking occurs.
