Description

Technical Field

[0001] The utility model relates to the technical field of pipeline connection equipment, in particular to a quick connector with good sealing performance. Background Technique

[0002] A quick connector is a connector that can achieve the connection or disconnection of pipelines without tools and is widely used in multiple industries. Two adjacent pipelines are connected by using the quick connector to pass through the two adjacent pipelines. However, the existing quick connector will cause the sealing performance to deteriorate during long-term use, so a pipeline quick connector with good sealing performance is needed.

[0003] There is a prior pipeline quick connector with good sealing performance (Publication No.: CN215060197U), which includes a connection main body. On the upper sides of the rear sides of both sides of the connection main body, a first semi-circular connection pipe is fixedly connected. At the middle of the upper side of the front end surfaces of the two first semi-circular connection pipes, a second semi-circular connection pipe is fixedly connected through a hinge. The connection main body includes a connection housing. In the utility model, the ring is slid in the middle from the semi-circular inclined chutes on the first semi-circular connection pipe and the second semi-circular connection pipe. The bottom surface of the slider on the ring is inclined on the opposite side. When it reaches the semi-circular inclined chute, under the action of the spring, the slider extends and retracts into the hole, so that the slider on the ring slides out of the semi-circular inclined chute. The ring is slid from the first semi-circular connection pipe and the second semi-circular connection pipe onto the connection main body, the first semi-circular connection pipe and the second semi-circular connection pipe are opened, and the pipelines are pulled out to both sides by rotating the pipelines.

[0004] The above existing device can dock the pipelines. However, when the above pipelines are docked, although the pipelines can be docked, there are still certain defects in the sealing performance at the connection without filling substances, so the sealing effect still needs to be improved.

[0005] In view of this, the present utility model is specifically proposed. Content of the Utility Model

The main glue injection box is arranged inside the main connection ring. The inner circumferential wall of the main glue injection box is provided with a main clamping circular groove, and a main clamping ring is sleeved on the outer wall of the main connection ring.

A semi-circular glue injection box 3 is rotatably clamped inside each connection ring member 2. The outer wall of one side of the semi-circular glue injection box 3 is evenly provided with glue injection holes 4 at equal intervals. The outer walls of the connection ring members 2 are both provided with semi-circular holes 5. One end of the outer wall of each semi-circular glue injection box 3 is communicated with a glue injection pipe 6. One end of the glue injection pipe 6 is located in the semi-circular hole 5. A vacuum cover 7 is hermetically inserted into the semi-circular hole 5.

[0024] Such as Figure 1 、Figure 3 and Figure 4 As shown in Figure 4 , the connecting pipe 1 is divided into a main pipe 101 and a secondary pipe 102, and the connecting ring member 2 is divided into a main connecting ring 8 and a secondary connecting ring 9. The outer surface of one end of the main pipe 101 is provided with a main thread 10, and the inner circumferential inner wall of the main connecting ring 8 is provided with a main internal thread 11. The main connecting ring 8 is threadedly engaged and arranged on the outer surface of one end of the main pipe 101. The outer surface of one end of the secondary pipe 102 is provided with a secondary thread 12, and the inner circumferential inner wall of the secondary connecting ring 9 is provided with a secondary internal thread 13. The secondary connecting ring 9 is threadedly engaged and arranged on the outer surface of one end of the secondary pipe 102. So that when the staff docks the main pipe 101 and the secondary pipe 102, at this time the staff rotates the main connecting ring 8 and the secondary connecting ring 9 respectively. At this time, the main connecting ring 8 and the secondary connecting ring 9 are docked. At this time, the staff should gradually rotate the secondary connecting ring 9 into the main connecting ring 8. At this time, the circumferential outer wall of the secondary connecting ring 9 and the circumferential inner wall of the main connecting ring 8 are tightly fitted with each other.

[0025] As Figures 3-6As shown in the figure, the semi-circular glue injection box 3 is divided into a main glue injection box 301 and a secondary glue injection box 302. The main glue injection box 301 is arranged inside the main connection ring 8. A main clamping circular groove is provided on the circumferential inner wall of the main glue injection box 301. A main clamping ring 14 is sleeved on the outer wall of the main connection ring 8. The main clamping ring 14 and the main clamping circular groove are rotationally clamped with each other. The secondary glue injection box 302 is arranged inside the secondary connection ring 9. A secondary clamping circular groove is provided on the circumferential inner wall of the secondary glue injection box 302. A secondary clamping ring 15 is sleeved on the outer wall of the secondary connection ring 9. The secondary clamping ring 15 and the secondary clamping circular groove are rotationally clamped with each other. T-shaped grooves 16 are provided on both end side walls of the main glue injection box 301. T-shaped blocks 17 are fixedly installed on both end side walls of the secondary glue injection box 302. Sealing holes are provided at one ends of the vacuum covers 7 in the semi-circular holes 5 at one ends of the main connection ring 8 and the secondary connection ring 9. One end of the glue injection pipe 6 is inserted into the sealing hole. A sealing plug 18 is hermetically inserted into the glue injection pipe 6. Pull rods 19 are symmetrically and fixedly installed on one outer wall of the vacuum cover 7. A micro check valve 20 is inlaid in the vacuum cover 7. So that when the staff rotates the secondary connection ring 9 into the main connection ring 8, at this time, the main glue injection box 301 and the secondary glue injection box 302 are docked, and the T-shaped groove 16 and the T-shaped block 17 are tightly inserted, so as to connect the main glue injection box 301 and the secondary glue injection box 302. Then the staff starts the glue injection work into the glue injection pipe 6 through the glue injection equipment arranged on one side of the main glue injection box 301 and the secondary glue injection box 302. At this time, the glue in the main glue injection box 301 and the secondary glue injection box 302 can be injected into the connection part of the main pipe 101 and the secondary pipe 102 through the glue injection hole 4. At this time, the staff starts to rotate the glue injection pipe 6 along the semi-circular hole 5, so as to comprehensively inject glue on the surface of the connection part of the main pipe 101 and the secondary pipe 102. At this time, the staff injects air into the glue injection pipe 6 through an external air pump, so as to spray out all the glue in the main glue injection box 301 and the secondary glue injection box 302. Then the staff presses the vacuum cover 7 forcefully into the semi-circular hole 5. At this time, the staff inserts the sealing plug 18 into the glue injection hole 4. Then the staff uses the air extraction equipment to extract the air inside the main connection ring 8 and the secondary connection ring 9 through the micro check valve 20, so as to maintain the tightness of the connection part of the main pipe 101 and the secondary pipe 102.
