Problems solved by technology

[0002] The connection position of the traditional injection device is the external thread of the Luer connector, and the matching part is usually the Luer connector nut. During the installation process, it needs to be rotated multiple times, which is not only troublesome to connect, but also has poor sealing effect and overall durability. The pressure capacity is also poor, which affects the injection efficiency

Abstract

The invention relates to a rapid sleeve connection joint and an injection device. The rapid sleeve connection joint comprises a male connector, a female connector, a spring and an outer hollow sleeve, wherein a plug groove is formed in the first end of the female connector, at least two gaps are formed in the side wall of the plug groove and extend from the open end of the plug groove to the bottom wall of the plug groove, an outer thread is arranged on the outer wall of the first end of the male connector, a convex line is arranged at one end of the inner wall of the plug groove, the first end of the male connector extends into the plug groove, the convex line is in clamped connection with the outer thread, a limiting protrusion is arranged at one end of the inner wall of the outer sleeve, an annular groove is formed in the outer wall of the first end of the female connector, the spring is located in the annular groove, the first end of the female connector is sleeved with the outer sleeve, and the limiting protrusion is in sliding fit with the annular groove. The rapid sleeve connection joint is convenient to dismount. Due to the combined effect of clamed connection matching of the spring, the outer sleeve, the male connector and the female connector, a sealing effect and pressure resisting capability are good after the male connector and the female connector are assembled, and loosening is not likely to occur.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an injection device. Background technique [0002] The connection position of the traditional injection device is the external thread of the Luer connector, and the matching part is usually the Luer connector nut. During the installation process, it needs to be rotated multiple times, which is not only troublesome to connect, but also has poor sealing effect and overall durability. The pressure capacity is also poor, which affects the injection efficiency. Contents of the invention [0003] Based on this, it is necessary to address the defects of the prior art and provide an injection device that not only has good pressure resistance, but also is easy to assemble and disassemble. [0004] Its technical scheme is as follows: [0005] An injection device, comprising a male joint, a female joint, a spring and a hollow jacket, the first end of the female joint is provided with a ...
