Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a sealing structure for JDG conduit joints. Background Technology

[0002] In building construction, many conduits are connected by direct connectors. For cast-in-place pre-embedded conduits, sealing is generally required. This is usually done by wrapping the structure with adhesive tape. However, this method is difficult to control in terms of quality. During the concrete pouring process, openings can easily occur, the seals can not be tight, and concrete can easily enter at the joints and block the conduits. This results in a large amount of maintenance later and is also unsightly.

[0003] There are also some sealing structures in the existing technology, such as the JDG pipe joint disclosed in patent CN218919889U, which can achieve a certain sealing effect, but it may be relatively troublesome to operate. In addition, there are also some thermoplastic pipe sealing structures in the existing technology, such as the JDG pipe joint sealing structure in CN204271566U, but it lacks a fixing and limiting structure, which may have the disadvantage of poor stability. Utility Model Content

[0004] This utility model provides a sealing structure for a JDG conduit connector, which can solve the problems pointed out in the background art.

[0005] A JDG conduit connector sealing structure includes a JDG conduit and a JDG direct sleeve. A heat shrink tubing connecting sleeve body is fitted onto the JDG direct sleeve. Heat shrink tubing is connected to both sides of the heat shrink tubing connecting sleeve body. The heat shrink tubing is fitted onto the JDG direct sleeve. The two ends of the JDG direct sleeve are respectively fitted and connected to the JDG conduit and locked and fixed by locking components.

[0006] Preferably, the heat shrink tubing is a heat shrinkable expansion tubing, and the two sides of the heat shrink tubing connecting sleeve body are respectively provided with extension sleeves extending to both sides, and the extension sleeves are used for storing the heat shrinkable expansion tubing.

[0007] Preferably, the heat shrink tubing connecting sleeve body has a positioning protrusion on the inner wall of the middle part, and the JDG direct sleeve has a positioning groove on the outer wall of the middle part that matches the positioning protrusion.

[0008] Preferably, both the positioning protrusion and the positioning groove are V-shaped.

[0009] Preferably, the locking element is the set screw on both sides of the JDG direct sleeve.

[0010] Beneficial effects: This utility model provides a JDG conduit joint sealing structure, which is relatively simple in structure, easy to operate, has a fixing and limiting structure, and has very good stability, making it very suitable for sealing JDG conduit joints.

[0015] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0016] Example 1:

[0017] like Figure 1-2 As shown in the figure, the JDG conduit connector sealing structure provided by this utility model includes a JDG conduit 1 and a JDG direct sleeve 2. A heat shrink tubing connecting sleeve body 4 is sleeved on the JDG direct sleeve 2. Heat shrink tubing 5 is connected to both sides of the heat shrink tubing connecting sleeve body 4. The heat shrink tubing 5 is sleeved on the JDG direct sleeve 2. The two ends of the JDG direct sleeve 2 are respectively sleeved and connected to the JDG conduit 1, and are locked and fixed by locking member 3.

[0018] In some embodiments, the heat shrink tubing 5 is a heat shrinkable expansion tube, that is, a heat shrinkable expansion tube with an expansion joint. The heat shrink tubing connecting sleeve body 4 has extension sleeves 41 extending to both sides. The extension sleeves 41 are used to store the heat shrinkable expansion tube, so that it can be stored in the extension sleeves 41, thereby not affecting the connection between JDG conduit 1 and JDG direct sleeve 2. After the connection is completed, the heat shrinkable expansion tube is pulled out to complete the heat shrink seal. The extension sleeves 41 also play a certain protective role, avoiding unnecessary damage to the heat shrinkable expansion tube before use.

[0019] In some embodiments, a positioning protrusion 6 is provided on the inner wall of the heat shrink tubing connecting sleeve body 4, and a positioning groove 7 that matches the positioning protrusion 6 is provided on the outer wall of the middle part of the JDG direct sleeve 2. Both the positioning protrusion 6 and the positioning groove 7 are "V" shaped. The locking member 3 is the set screw on both sides of the JDG direct sleeve 2. Through positioning and matching, the heat shrink tubing connecting sleeve body 4 can be centered, ensuring the connection quality. It can also avoid some unnecessary movement during operation, improve stability, and ensure the connection quality.

[0020] The operation method of this utility model is as follows: The JDG direct sleeve 2 is inserted into the heat shrink tubing 5 and the heat shrink tubing connecting sleeve body 4, and positioned and limited by the positioning protrusion 6 and the positioning groove 7; the two ends of the JDG direct sleeve 2 are respectively inserted into the JDG conduit 1 and screwed into the locking piece 3 for fixation; finally, the heat shrink tubing is pulled out and wrapped around the joints on both sides. The heat shrink tubing 5 is heated with a hot air gun or the like to shrink the heat shrink tubing 5, so as to achieve the purpose of sealing the joint.

[0021] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
