DETAILED DESCRIPTION
[0015] The present invention will now be described in detail with reference to the accompanying drawings: as shown in the drawings Figs. 1 to 3 As shown, this utility model includes a brass tube body 1, with mounting ports 2 at both the left and right ends of the brass tube body 1, an insertion interface 3 at the upper end of the brass tube body 1, and a base 4 at the lower end of the brass tube body 1. The base 4 and the insertion interface 3 are symmetrically distributed along the center of the brass tube body 1. Mounting lugs 41 are provided at both the front and rear ends of the base 4, and the brass tube body 1 is mounted and fixed on the mounting working surface by means of the mounting lugs 41. A toothed densification unit 5 for increasing the sealing performance of the pipeline is provided on the outer peripheral wall of the mounting port 2, and a clamping unit 6 for clamping the pipeline is installed on the outer peripheral wall of the mounting port 2, and the clamping unit 6 corresponds to the toothed densification unit 5.
[0016] The bottom surface of the mounting ear block 41 is flush with the bottom surface of the base 4, and the mounting ear block 41 is provided with mounting holes 42.
[0017] The inner circumferential wall of the insertion interface 3 is provided with an internal thread 31, and the upper end of the outer circumferential wall of the insertion interface 3 is provided with a ring-shaped sealing protrusion 32.
[0018] The toothed densification unit 5 includes several rings of protrusions 51 distributed along the axial direction of the brass tube body 1, with the protrusions 51 being evenly spaced.
[0019] The clamping unit 6 includes a gasket 61 and a copper sleeve 62. The gasket 61 is installed and fixed in a stepped groove 21 on the outer peripheral wall of the mounting port 2. The stepped groove 21 is located at the rear end of the toothed densification unit 5. One end of the copper sleeve 62 is fixed to a stepped mounting groove 63 on the gasket 61 by an interference fit. A cap 7 is inserted into the other end of the copper sleeve 62. Two symmetrically distributed observation holes 64 are provided on the sleeve wall of the copper sleeve 62. The observation holes 64 are located on the side of the stepped groove 21.
