As a further improvement of the utility model: and a sealing ring is arranged at the joint of the interior of the valve chamber and the glue injection nozzle.
As a further improvement of the utility model: the flow stopping valve comprises a spring and a ball valve, the spring is connected with the ball valve, and the spring is installed on the glue injection nozzle.
As a further improvement of the utility model: the lower extreme that advances to glue mouthful sets up the arc structure, the arc structure with ball valve looks adaptation.
As a further improvement of the utility model: and guide columns are further arranged in the valve chamber and are arranged on two sides of the flow stopping valve.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model discloses the injecting glue is chewed and is passed through between screw thread and the valve room adjustable, chews through the rotatory injecting glue that makes progress and can make the check valve top tightly advance jiao kou, and then the rifle is glued in locking to effectively prevent to leak and glue.
2. The utility model discloses the injecting glue is chewed and is glued through threaded connection between the cavity, and only ends the flow valve and set up on the injecting glue is chewed, can dismantle the injecting glue and chew and maintain the change to only flowing the valve structure.
Drawings
Fig. 1 is a schematic sectional view of the present invention.
Fig. 2 is a schematic front view of the structure of the present invention.
In the figure: 1 molten glue cavity, 2 injecting glue are chewed, 3 valve rooms, 4 screw threads, 5 advance jiao kou, 6 play jiao kou, 7 check valves, 8 sealing washers, 9 guide posts, 10 springs, 11 ball valves, 12 arc structures.
Detailed Description
The invention will now be further described with reference to the accompanying drawings, in which:
the utility model discloses a detailed description:
referring to fig. 1 to 2, the stop valve structure comprises a molten glue cavity 1 and a glue injection nozzle 2, wherein the glue injection nozzle 2 is installed in the molten glue cavity 1, a valve chamber 3 is arranged at the lower end of the molten glue cavity 1, the upper part of the glue injection nozzle 2 is installed in the valve chamber 3 in a matching manner through a thread 4, and the glue injection nozzle 2 and the valve chamber 3 are adjustable through the thread 4; the glue inlet 5 is formed in the valve chamber 2, the glue inlet 5 penetrates through the molten glue cavity 1 and the valve chamber 3, the top of the glue injection nozzle 2 is arranged in the valve chamber 3, the glue injection nozzle 2 is provided with a glue outlet 6 and a check valve 7, the glue outlet 6 is communicated into the valve chamber 3, the check valve 7 is arranged at the top of the glue injection nozzle 2, and the check valve 7 is arranged under the glue inlet 5 and can block the glue inlet 5.
A sealing ring 8 is arranged at the joint of the interior of the valve chamber 3 and the glue injection nozzle 2, guide columns 9 are further arranged in the valve chamber 3, and the guide columns 9 are arranged on two sides of the stop valve 7.
The first embodiment is as follows:
in this embodiment, the check valve 7 comprises a spring 10 and a ball valve 11, the spring 10 is connected with the ball valve 11, and the spring 10 is installed on the glue injection nozzle 2; the lower end of the glue inlet 5 is provided with an arc-shaped structure 12, and the arc-shaped structure 12 is matched with the ball valve 11. The utility model discloses during the use, the melten gel cavity 1 lets in compressed air, and on compressed air's pressure passed through the sizing material and transmitted ball valve 11, spring 10 was compressed when pressure exceeded spring 10's elasticity, and ball valve 11 moves down, advances jiao kou 5 and valve chamber 3 and communicates with each other. The glue material in the glue melting cavity 1 is injected into the valve chamber 3 and enters the glue injection nozzle 2 to be injected from the glue outlet 6 to realize glue injection. After glue injection is finished, the glue melting cavity 1 is communicated with the atmosphere, the ball valve 11 moves upwards under the action of the spring 10, and the glue inlet 5 is blocked by the ball valve 11 to stop glue injection.
If the glue leakage phenomenon appears after the glue injection nozzle is used for a period of time, the elasticity of the spring 10 is reduced, at the moment, the glue injection nozzle 2 is screwed upwards, and the glue leakage phenomenon can be solved by compensating the elasticity of the spring 10.
Further, when the glue gun does not need to be used, the height of 2 is chewed to rotatable glue injection, makes 2 top tight springs 10 of glue injection mouth, and springs 10 push up tight ball valve 11 and can't move in 12 departments of arc structure, and then locks the glue gun, guarantees the safe in utilization of glue gun.
Furthermore, when the stop valve 7 is damaged and the glue inlet 5 or the glue outlet 6 is blocked, the glue injection nozzle 2 can be rotationally detached for maintenance.
In summary, after reading the present disclosure, those skilled in the art can make various other corresponding changes without creative mental labor according to the technical solutions and concepts of the present disclosure, and all of them are within the protection scope of the present disclosure.
