Abstract
The utility model discloses a pipe joint structure, which comprises a connection pipe, of which the end is provided with a horn opening, a pipe joint and a pipe nut with a frustum, wherein the end of the connection pipe, which is provided with the horn opening, is stopped in the frustum of the pipe nut; the pipe nut is in threaded connection with the pipe joint; a round chamfer is arranged at the end of the pipe joint, and the shape of the round chamfer is matched with that of the frustum of the pipe nut; and an integrated insertion part is arranged at the end of the pipe joint, and can penetrate through the pipe nut and extend into a pipe section within the horn opening of the connection pipe. A protection sleeve is arranged on the pipe nut, and the insertion part is arranged on the pipe joint, so that the pipe joint structure can effectively stop the horn opening of the connection pipe from vibrating, and a phenomenon that the connection pipe is fractured at the root of the horn opening is avoided.
Description
Technical field
The utility model relates to a kind of pipe joint structure.
Background technique
Make the field at the family expenses air-conditioning, domestic air conditioner is formed and is mainly comprised: compressor, condenser, throttling arrangement, vaporizer four big parts, also have accessories such as stop valve in addition, and indoor and outdoor machine connects through indoor and outdoor connecting pipe.Like Fig. 1, shown in 2, present Placement: the horn mouth shape is expanded at two of indoor and outdoor connecting pipe 3 respectively, and the angle of inclination of horn mouth 31 is consistent with the rounded corner angle of pipe joint of indoor set 1 and outdoor unit high low pressure valve joint.Pipe nut 2 through copper is connected connecting tube with joint.Because the horn mouth angle of inclination of indoor and outdoor connecting pipe is consistent with pipe joint rounded corner 12 angles; In the time will managing nut tightly with pipe joint or high low pressure valve joint; The horn mouth of indoor and outdoor connecting pipe is close to the rounded corner surface of joint, makes indoor and outdoor connecting pipe and joint sealing.The horn mouth of this indoor and outdoor connecting pipe is formed by the direct enlarging of indoor and outdoor connecting pipe, and the wall thickness of indoor and outdoor connecting pipe own has only about 0.75mm, so the horn mouth wall ratio that expands is thinner, back horn mouth sealing cone is installed can be become thinner because of the fastening force effect.The horn mouth root just reduces because of machining deformation intensity originally, and after indoor and outdoor connecting pipe was tightened with this kind mode, bell-mouthed root was fragile especially.According to lever principle, the horn mouth root is the place of the stressed maximum of connecting tube, and is the weakest place here.Outdoor unit is assemblied in the outdoor, and the indoor and outdoor connecting pipe that exposes in the outdoor generally all has certain-length unsettled, and under the effect of external force such as exposing to wind and rain, unsettled connecting tube will produce and rock.Present connecting tube copper nut through hole and the gap between the connecting tube be big (in order to improve efficiency of assembling); Connecting tube after the installation amplitude of oscillation under external force is bigger; So the horn mouth that connecting tube is connected with outdoor stop valve will rupture, the reliability of air conditioner can't to ensureing.Horn mouth at the installation process indoor and outdoor connecting pipe of air conditioner is difficult to align with pipe joint, assembles by force if under situation about not lining up, will manage nut, can cause the horn mouth distortion of connecting tube, can cause freezing medium leakage when serious.
The model utility content
The utility model purpose provides a kind of pipe joint structure of strengthening join strength, preventing the brittle failure of connecting tube horn mouth in order to overcome the deficiency that above-mentioned prior art exists.
The technological scheme that the utility model adopts is: a kind of pipe joint structure; Comprise connecting tube, the pipe joint of expanding end, the pipe nut of band frustum; The flared end of said connecting tube by backstop the pipe nut frustum in; Said pipe nut is threaded with pipe joint, and the end of said pipe joint is provided with rounded corner, and said rounded corner is suitable with the frustum shape of pipe nut; The end of said pipe joint also is provided with incorporate insertion part, and institute can pass the insertion part pipe nut and extend into the connecting tube enlarging with in the interior pipeline section.
The integrated protective casing that is provided with in the frustum end of said pipe nut.
The protective casing length of the insertion part of said pipe joint and pipe nut tap you portion about equally.
Compared with prior art, the utlity model has following advantage:
The pipe joint structure of the utility model is through increasing protective casing on the nut, on pipe joint, increase the insertion part at pipe, can stop effectively that connecting tube is bell-mouthed to be rocked, and prevents the phenomenon of connecting tube in the embrittlement of horn mouth root.

Fig. 4 is the pipe nut structure schematic representation of the utility model;
Fig. 5 is that the pipe of the pipe joint structure of the utility model connects schematic representation.
Embodiment
The pipe joint structure of the utility model comprises connecting tube 3, pipe joint 1, pipe nut 2; The two ends enlarging of connecting tube; The frustum 22 of pipe nut is enclosed within the enlarging position of connecting tube, and the screw section 21 of pipe nut is connected with the outside thread 11 of pipe joint, thereby connecting tube and pipe joint are linked together.The other end of pipe joint 1 connects takes over 4, thereby indoor and outdoor machine is connected through pipe joint structure.The enlarging position of connecting tube is a horn mouth 31; The end of pipe joint is provided with rounded corner 12; This rounded corner is suitable with the frustum shape of pipe nut, and the rounded corner of pipe joint can make its sealing on the horn mouth sealing cone that is pressed in the frustum inner chamber of managing nut tightly with indoor and outdoor connecting pipe in the time of can guaranteeing to manage nut screwing clamping.The end of pipe joint also is provided with incorporate insertion part 13, and institute can pass the insertion part pipe nut and extend into the connecting tube enlarging with in the interior pipeline section, and the about 20mm in insertion part is long, and external diameter is slightly less than the internal diameter of indoor and outdoor connecting pipe.The integrated protective casing 23 that is provided with in frustum 22 ends of pipe nut, pipe nut protective casing internal diameter is slightly larger than the external diameter of connecting tube, but more young than loudspeaker, and during assembling, the protective casing 23 of pipe nut is enclosed within the outer wall of horn mouth 31.After installing; Because pipe nut protective casing internal diameter is slightly larger than the external diameter of connecting tube and the internal diameter that the pipe joint external diameter is slightly less than connecting tube; Gap between both and the connecting tube is smaller and certain insertion depth arranged; When even the amplitude that indoor and outdoor connecting pipe rocks is bigger, the intensity at horn mouth position is also resisted torsion enough, thereby has protected connecting tube.
Claims (3)
1. pipe joint structure; Comprise connecting tube, the pipe joint of expanding end, the pipe nut of band frustum, in the frustum of pipe nut, said pipe nut is threaded with pipe joint the flared end of said connecting tube by backstop; The end of said pipe joint is provided with rounded corner; Said rounded corner is suitable with the frustum shape of pipe nut, and it is characterized in that: the end of said pipe joint also is provided with incorporate insertion part, and institute can pass the insertion part pipe nut and extend into the connecting tube enlarging with in the interior pipeline section.
