Adopt above-mentioned technical scheme, swivel nut and the screw thread section cooperation that corresponds, make when rotating the swivel nut, the swivel nut can body relatively carry out the displacement, when the swivel nut moves towards body middle part, the first tight cover that expands can be extruded to the platform of contradicting, thereby make the first tight relative body of the tight cover that expands carry out the displacement, thereby expand trachea and body and tightly reach the purpose of connecting, it is troublesome both to have solved the connection between the body, can prevent to connect the relative body of back trachea and rotate again, simple structure simple to operate, and it is also more convenient to dismantle when body or trachea damage.

The utility model discloses a further setting again: the first tight cover macrostoma of expanding end position still is equipped with the tight cover of second expansion, and the tight cover of second expansion is including grafting portion and conflict portion, and grafting portion inserts and establishes in the tight cover of first expansion, and conflict portion is contradicted at the conflict bench.

Adopt above-mentioned further setting again, expand through the second and tightly overlap and can make first tight cover that expands and trachea expand tightly for more stable when using, prevent that the relative first tight cover that expands of trachea from rotating.

The utility model discloses a further setting again: a clamping portion used for clamping the wrench is arranged between the first connecting end and the second connecting end, and a plurality of clamping planes symmetrically arranged are arranged on the clamping portion.

Adopt above-mentioned further setting again, the spanner can press from both sides and establish and be used for fixed body on pressing from both sides the plane in the assembly, prevents that the body from rotating in the assembly, can be more convenient find the impetus in the assembly for it is more convenient in the assembly.

The utility model discloses a further setting: be equipped with first conical surface on the inside wall at body port department, first conical surface laminates with first tight cover outer peripheral face that expands mutually.

Adopt above-mentioned further setting, can increase the body and the first contact surface between the tight cover that expands for connect more stable, the leakproofness is better between the two.

The utility model discloses a further setting: the second conical surface is arranged on the outer peripheral surface of the plug-in part of the second expansion sleeve, a third conical surface matched with the second conical surface is arranged on the inner side wall of the first expansion sleeve, and the second conical surface and the third conical surface are attached to each other.

Adopt above-mentioned further setting, can increase the first tight cover of expanding and the second expands the contact surface between the tight cover for connect more stable, the leakproofness is better between the two, thereby the sealed effect of further increase.

Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings:

herein, inward means a direction toward the middle of the tube, and outward means a direction spreading from the middle of the tube to both ends.

The utility model discloses a gas pipe joint, which comprises a pipe body 1, in the implementation case of the utility model, one end of the pipe body 1 is a first connecting end 111, the other end is a second connecting end 112, the outer peripheral surfaces of the first connecting end 111 and the second connecting end 112 are both provided with thread sections 2, each thread section 2 is provided with a screw sleeve 3 matched with the thread section 2, the connecting part of the screw sleeve 3 and the thread section 2 on the pipe body 1 is provided with a first expansion sleeve 4, the outer peripheral surface of the first expansion sleeve 4 is in a conical arrangement, the small end of the first expansion sleeve 4 extends into the pipe body 1, the big end extends outwards, the inner side wall of the screw sleeve 3 is provided with an abutting platform 311 for extruding the big end of the first expansion sleeve 4, the screw sleeve 3 is matched with the corresponding thread section 2, so that when the screw sleeve 3 rotates, the screw sleeve 3 can displace relative to the pipe body 1, when the screw sleeve 3 moves towards the middle part of the pipe body, conflict platform 311 can extrude the first tight cover 4 that expands to make the first tight cover 4 of expanding carry out the displacement for body 1 relatively, thereby expand tightly with trachea and body 1 and reach the purpose of connecting, both solved the connection between body 1 and the trachea troublesome, can prevent to connect back trachea relatively body 1 again and rotate, simple structure simple to operate dismantles also more conveniently when body 1 or trachea damage in addition.

The tight cover 5 that expands of second still is equipped with in the first tight cover 4 macrostoma position that expands, and the tight cover 5 that expands of second is including grafting portion 511 and conflict portion 512, and grafting portion 511 is inserted and is established in the tight cover 4 of first expanding, and conflict portion 512 is contradicted on conflict platform 311, expands tight cover 5 through the second and can make the tight cover 4 of first expanding and trachea expand tightly for it is more stable when using, prevents that the relative tight cover 4 of first expanding of trachea from rotating.

Be equipped with between first link 111 and the second link 112 and be used for the spanner to press from both sides the portion of establishing 6 that presss from both sides that establishes, press from both sides the portion of establishing 6 and be equipped with the clamp plane 611 that a plurality of symmetry set up, the spanner can press from both sides and establish and be used for fixed body 1 on pressing from both sides the plane 611 during the assembly, prevents that body 1 from rotating in the assembly, can more conveniently find the impetus in the assembly for it is more convenient in the assembly.
