It is managed.
Detailed description of the invention
It, below will be right in order to illustrate more clearly of specific embodiment of the present invention or technical solution in the prior art
Specific embodiment or attached drawing needed to be used in the description of the prior art are briefly described.In the accompanying drawings, similar element
Or part is generally identified by similar appended drawing reference.In attached drawing, each element or part might not be drawn according to actual ratio.
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the schematic diagram of the section structure of A-A in Fig. 1.
Main element symbol description is as follows:
Tube body 1, threaded connector 2, mounting hole 3, removable pin 4, shield 5, spring 6, connecting rod 7, sealing plate 8, evacuation port 9,
Baffle 10 adjusts bolt 11, retention bead 12.
Specific embodiment
It is described in detail below in conjunction with embodiment of the attached drawing to technical solutions of the utility model.Following embodiment is only
For clearly illustrating the technical solution of the utility model, therefore it is only used as example, and it is originally practical to cannot be used as a limitation limitation
Novel protection scope.
It should be noted that unless otherwise indicated, technical term or scientific term used in this application should be this reality
The ordinary meaning understood with novel one of ordinary skill in the art.
As shown in Figure 1 and Figure 2, a kind of gas nozzle standard set-up, including tube body 1,1 both ends of tube body are equipped with screw thread
Connector 2 is provided with mounting hole 3 on 1 outer wall of tube body, is equipped with removable pin 4 in the mounting hole 3,4 outer wall of removable pin with
3 inner wall airtight connection of mounting hole；The mounting hole 3 is externally provided with shield 5, is equipped with spring 6, described 6 one end of spring in the shield 5
Against 5 upper end inner wall of shield, the other end is against 4 upper end of removable pin；4 lower end of removable pin is equipped with connecting rod 7, the connecting rod
7 upper ends are fixedly connected with removable pin 4, and 7 lower end of connecting rod is connected with sealing plate 8, the sealing plate 8 penetrate 1 side wall of tube body and with
1 side wall airtight connection of tube body.
In the present embodiment, 2 one end of threaded connector at 1 both ends of tube body is connect with nozzle, and the other end connects gas source, when wherein
Be passed through compressed air air pressure it is excessive more than spring 6 apply pressure when, removable pin 4 will be pushed up by compressed air, activity
Pin 4 will pull sealing plate 8 to move up when moving up by connecting rod 7, and enter the length in tube body 1 by sealing plate 8
