Abstract
The utility model discloses a pipe joint, which comprises a first joint and a second joint, wherein external screw threads are arranged on the first joint, internal screw threads are arranged on the second joint, the connection between the first joint and the second joint is realized after the internal screw threads and the outer screw threads are matched, the second joint is provided with a connecting surface at the tail end of the internal screw threads, a fixing groove is arranged on the connecting surface, the first joint is provided with a connecting lug boss at the top end of the external screw threads, small holes are formed in the connecting lug boss in the radial direction, and spring balls are arranged in the small holes and are embedded in the small holes after being fixed through fixed elastic sheets. The connecting surface with the fixing groove is arranged at the tail end of the internal screw threads in the second joint, the top end of the external screw threads in the first joint are provided with the spring balls fixed through the fixed elastic sheets, after the matched connection of the first joint and the second joint, the spring balls can be embedded into the fixing groove, the position limiting function is reached, and the connection firmness is enhanced. Compared with the prior art, the pipe joint has the advantages that the connection is firmer, the damage cannot be easily caused, and the service life is longer.
Description
[technical field]
The utility model relates to connection device technical field, particularly a kind of pipe coupling.
[background technique]
Joint is generally used for the joint of pipeline, it comprises the first joint and the second joint, in prior art, generally on the first joint, outside thread is set, on the second joint, internal thread is set, the first joint and the second joint are connected and fixed after coordinating by internal thread and outside thread, the end of internal thread arranges sealing surface, on externally threaded top, arrange can with the close-fitting step of sealing surface, such structure is relatively simple, also be convenient to produce, yet only in the fixing mode that is spirally connected, soundness is poor, after the service time through certain, in easily causing, outside thread is damaged, fracture, cause joint to connect insecure, when serious, joint will lose efficacy.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of pipe coupling, can improve connectivity robustness, increases the service life.
For achieving the above object, the utility model proposes a kind of pipe coupling, comprise the first joint and the second joint, on the first described joint, be provided with outside thread, on the second joint, be provided with internal thread, internal thread is realized the first joint after coordinating with outside thread and is connected with the second joint, the second described joint is provided with junction surface at the end of internal thread, on junction surface, offer fixed groove, the first joint is provided with connection boss on externally threaded top, connect on boss and radially offer aperture, in described aperture, be provided with hoodle, described hoodle is fixedly embedded in aperture through fixation spring tab.
As preferably, the first described joint is provided with sealing surface at externally threaded end, and the top of the second joint is provided with the secondary sealing area matching with sealing surface, on described sealing surface, is provided with seal ring.
As preferably, the cross section of described sealing surface is arc, and seal ring is fixed on the center of sealing surface.
As preferably, in described aperture, be provided with coil tension spring, hoodle is close to described coil tension spring.
The beneficial effects of the utility model: the utility model arranges the junction surface with fixed groove by the end of internal thread in the second joint, in the first joint, externally threaded top arranges the hoodle of being fixed by fixation spring tab, after the first joint and the second joint are connected, hoodle will be embedded in fixed groove, reach limit function, strengthen the soundness connecting, compared with prior art, the utility model connects more firm, not fragile, has longer working life.
Feature of the present utility model and advantage will be elaborated by reference to the accompanying drawings by embodiment.
