Description

Metal pipe fitting joint connecting device Technical Field The utility model relates to the technical field of pipe fitting connection, in particular to a pipe fitting joint connection device. Background The statements herein merely provide background art related to the present disclosure and may not necessarily constitute prior art. At present, metal pipe fittings are increasingly applied to various fields, but because of the limitations of production technology and transportation conditions, the metal pipe fittings cannot be directly processed to a larger length, and at present, the pipe fittings are generally processed to a specific length uniformly, and then are spliced on site, so that the length meets the use requirement. In order to better serve clients and improve the satisfaction of the clients, the pipe manufacturers are generally required to provide technical support to ensure the reliability of pipe connection, and higher technical requirements are provided for the pipe manufacturers. The prior art generally controls the propping force of the end part of the pipe fitting in an artificial mode, but in the process of splicing the pipe fitting in an artificial mode, the propping degree of the end part of the pipe fitting cannot be accurately controlled, so that liquid leakage is easy to occur when the pipe fitting is used for liquid conveying. Disclosure of utility model The present disclosure provides a metal pipe fitting joint connecting device, which can solve at least one of the above technical problems. In order to achieve the above purpose, the metal pipe fitting joint connecting device of the present disclosure comprises a receiving sleeve and an inserting block, wherein the receiving sleeve and the inserting block are sleeved or welded on two pipe fittings to be connected, and the two pipe fittings are respectively a first pipe fitting and a second pipe fitting. The bearing sleeve is provided with a first groove and a second groove which are communicated with each other, the size of the second groove is matched with the cross section of the insertion block, a third groove is formed in the side wall of the second groove, a fourth groove is formed in the outer portion of the side wall of the insertion block, a spring is arranged at the bottom of the fourth groove, a stop block is arranged at the upper portion of the spring, one end of the spring is fixedly connected with the bottom of the fourth groove, the other end of the spring is fixedly connected with the stop block, and a fifth groove is formed in the insertion block.
