[0002] When applying for the present invention, the applicant found through search that a Chinese patent disclosed a "an internally threaded metal insert water supply elbow", and its application number is "CN202022198389.9". This patent mainly eliminates the cavity undercut formed by the concave outer surface of the main end of the traditional structural product. When the reference plane passing through the central axis of the insert end and perpendicular to the central symmetry plane of the product is selected as the mold parting surface for cavity parting, the cavity position corresponding to the outer surface of the injection molding end can be demolded normally, and the core corresponding to the insert end moves in the horizontal direction and is maintained on the mold parting surface, while the movement direction of the core corresponding to the injection molding end is along the normal direction of the mold parting surface. When multiple groups of symmetrical products are arranged along the normal direction of the horizontal plane, the activities of the cores corresponding to the insert end and the injection molding end will not interfere with each other. At this time, the mold demolding quantity of the product can be set to 1 out of 4 cavities or more.

[0003] The above patents are intended to increase the number of mold demolding of products, but do not further optimize the metal inserts, fail to improve the efficiency of the use of the metal inserts, and the utilization efficiency of the metal inserts is low. They only serve as accessories. It would be better to use the metal inserts as the main carrier for further effective utilization.

[0004] For this purpose, we propose an internally threaded metal insert. Utility Model Content

[0007] According to the internally threaded metal insert, the insert end body is in an inverted "T" shape. The purpose of setting the insert end body in an inverted "T" shape is to more conveniently demonstrate the function of the structure of the internally threaded metal insert.

[0008] According to the internal thread metal insert, the horizontal insert end center axis and the non-main body engaging piece center axis form a 90° angle. The horizontal insert end center axis and the non-main body engaging piece center axis form a 90° angle to achieve better support and fixation.

[0009] According to the internal thread metal insert, the main engaging part is a three-dimensional hollow cross ring. The main engaging part is set as a three-dimensional hollow cross ring in order to better play the role of flexible combination.

[0010] According to the internal thread metal insert, the engaging edge line of the insert end is an inner beveled surface. The engaging edge line of the insert end is formed into an inner beveled surface to achieve a fixed connection with the outer beveled surface of the engaging edge of the engaging main part.

[0011] According to the internal thread metal insert, the multiple engagement edges of the engagement main part are external beveled surfaces. The engagement edges of the engagement main part are formed into external beveled surfaces to achieve a fixed connection with the internal beveled surfaces of the engagement edges at the end of the insert.

[0012] Beneficial effects of the utility model:

[0013] The internally threaded metal insert can realize the free combination of special-shaped insert ends by freely assembling the main clamping part, the insert end and the non-main clamping piece. Increasing the insert end and reducing the non-main clamping piece can increase the interactive flow direction of the pipeline. Reducing the insert sleeve and increasing the non-main clamping piece can make it a one-way channel. This makes it convenient to deal with various special situations and increases the use of the internally threaded metal insert. At the same time, only the number of the insert end and the non-main clamping piece needs to be increased or decreased to achieve the purpose of changing the flow direction of the pipeline, which effectively reduces the difficulty of use for workers and greatly improves the work efficiency of workers.

A thread 3 is provided inside the insert end 1, and the thread 3 is only on one side of the reinforcing rib socket 2 inside the insert end 1. The thread 3 is a triangular pattern single-track multi-turn thread, so that its meshing effect is better, and a clamping edge line 6 is provided at the tail of the insert end 1, and a rubber ring is pasted on the top of the clamping edge line 6, and a dust-proof film is pasted on the top of the rubber ring. A main engaging part 5 is arranged above the engaging edge line 6, and the main engaging part 5 is provided with a plurality of engaging edges 4, a rubber ring is pasted on the top of the engaging edge, and a dust-proof film is pasted on the top of the rubber ring. The insert end 1 is fixedly connected to the engaging edge 4 on one side of the main engaging part 5 through the tail engaging edge line 6, and a 90° angle is formed between the central axes of each insert end 1. The angle is set to 90° so that the connected pipes do not affect each other. A non-main engaging piece 7 is provided at the bottom of the main engaging part 5, and the function of the non-main engaging piece 7 is opposite to that of the insert end 1. The non-main engaging piece 7 fills the engaging edge 4 on the side of the main engaging part 5 where the insert end 1 is not provided, a rubber ring is pasted on the top of the engaging edge line of the non-main engaging piece 7, and a dust-proof film is pasted on the top of the rubber ring.

[0024] The main body of the insert end 1 is in an inverted "T" shape, which has a three-dimensional flow guide effect and better plays its role. The central axis of the horizontal insert end 1 and the central axis of the non-main body snap-fitting piece 7 form a 90° angle to ensure the pipeline flow between the horizontal insert end 1 and the non-main body snap-fitting piece 7. The snap-fitting main part 5 is a three-dimensional hollow cross ring, which is the hollow sphere dug out and re-attached by two cylinders.
