Description

Technical Field

[0001] The utility model relates to the field of copper inlays, in particular to a copper inlay with a built-in sealing ring. Background Art

[0002] Copper inserts are commonly known as copper inlays, copper inlays, inlaid copper nuts, injection molded copper nuts, etc. They are a kind of copper accessories embedded in plastic and have a wide range of uses. Copper inserts are a common accessory in the field of PPR pipes and have a wide range of uses. They mainly play a connecting role. Common copper inserts are made by direct turning of hexagonal bars. The process is simple. As an inlay, it is firm and not easy to rotate after injection molding and has good engineering performance.

[0003] Because brass has good thermal conductivity, the heated copper insert can also quickly transfer heat to the plastic part, thereby softening the area around the plastic hole, and quickly pressing the copper insert into the hole of the pipe. At this time, the embossing process is used on the outer diameter of the pipe, so that the formed pipe and the product form a certain friction and bite force, which can fix it inside and prevent it from falling off.

[0004] The copper inlays currently in use on the market need to be heated before use. This behavior is not only dangerous but also inconvenient to install. Therefore, a copper inlay that can be installed quickly is designed. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a copper insert with a built-in sealing ring to solve the technical problem of cumbersome installation of traditional structures.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a copper inlay with a built-in sealing ring, comprising a main body, both sides of the outer wall of the main body are connected to limit blocks, the outer wall of the main body is located in the middle of the main body and is connected to a top block surrounding the main body, the outer wall of the main body is located in the middle of the top block and the two limit blocks and is sleeved with a slider, the outer wall of the main body is located on the side of the two sliders away from the top block and is connected to a clamping block surrounding the main body between the corresponding limit blocks, a number of spring pieces that bypass the clamping blocks are connected between the two sliders and the corresponding limit blocks, and the outer wall of the slider and the side of all the spring pieces away from the axis of the main body are provided with damping.

[0007] By adopting the above technical solution, the main body is inserted into the pipe, and the slider is engaged with the inner wall of the pipe. When the pipe moves outward, the slider is driven to move outward together. At this time, the outward movement of the slider causes the spring sheet in contact with the block to bend outward, so that the spring sheet applies pressure to the inner wall of the pipe. As the pipe moves, the force applied by the spring sheet to the pipe also increases, thereby preventing the pipe from falling off.

[0008] The utility model is further configured that each of the limit blocks is sleeved with a rubber ring.

[0009] By adopting the above technical solution, the rubber ring sleeved on the outer wall of the limit block is used for sealing between the main body and the pipeline.

[0010] The utility model is further configured that a disc spring is connected between one side of each sliding block facing the top block and the top block, and each disc spring is sleeved on the outer wall of the main body.

[0011] By adopting the above technical solution, when not installed, the disc spring pulls the sliding block to the initial position.

[0012] The utility model is further configured that the outer wall of the top block is connected to the outer shell, and the outer shell, the top block and the sliding block cooperate with each other.

[0013] By adopting the above technical solution, the outer shell is used to protect the connection of the pipeline from being damaged.

[0014] In summary, the utility model mainly has the following beneficial effects:

[0015] The utility model inserts a main body into the pipeline, and a rubber ring sleeved on the outer wall of the limit block is used for sealing between the main body and the pipeline. At this time, the slider is engaged with the inner wall of the pipeline. When the pipeline moves outward, the slider is driven to move outward together. At this time, the outward movement of the slider causes the spring sheet in contact with the block to bend outward, so that the spring sheet applies pressure to the inner wall of the pipeline. As the pipeline moves, the force applied by the spring sheet to the pipeline also increases, thereby preventing the pipeline from falling off. The outer shell is used to protect the connection of the pipeline from being damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0022] The following describes an embodiment of the utility model based on its overall structure.

[0023] A copper insert with a built-in seal, such as Figure 1-4 As shown, it includes a main body 1, both sides of the outer wall of the main body 1 are connected to limit blocks 2, the outer wall of the main body 1 is located in the middle of the main body 1 and is connected with a top block 6 surrounding the main body 1, the outer wall of the main body 1 is located in the middle of the top block 6 and the two limit blocks 2 and is sleeved with a slider 3, the outer wall of the main body 1 is located between the side of the two sliders 3 away from the top block 6 and the corresponding limit blocks 2, and a clamping block 4 surrounding the main body 1 is connected, and the two sliders 3 and the corresponding limit blocks 2 are connected with a plurality of spring pieces 5 bypassing the clamping block 4, and the outer wall of the slider 3 and the side of all the spring pieces 5 away from the axis of the main body 1 are provided with damping, and the main body 1 is inserted into the pipeline. At this time, the slider 3 is engaged with the inner wall of the pipeline, and when the pipeline moves outward, it drives the slider 3 to move outward together. At this time, the slider 3 moves outward so that the spring piece 5 in contact with the clamping block 4 bends outward, so that the spring piece 5 applies pressure to the inner wall of the pipeline. As the pipeline moves, the force applied by the spring piece 5 to the pipeline also increases, so as to prevent the pipeline from falling off.

[0024] Each limit block 2 is sleeved with a rubber ring 9, and the rubber ring 9 sleeved on the outer wall of the limit block 2 is used for sealing between the main body 1 and the pipeline. A disc spring 7 is connected between the side of each slider 3 facing the top block 6 and the top block 6, and each disc spring 7 is sleeved on the outer wall of the main body 1. When not installed, the disc spring 7 pulls the slider 3 to the initial position, and the outer wall of the top block 6 is connected to the outer shell 8, and the outer shell 8, the top block 6 and the slider 3 cooperate with each other. The outer shell 8 is used to protect the connection of the pipeline from being damaged.

[0025] Working principle: insert the main body 1 into the pipe until the pipe contacts the top block 6. The rubber ring 9 sleeved on the outer wall of the limit block 2 is used to seal the main body 1 and the pipe. At this time, the slider 3 is engaged with the inner wall of the pipe. When the pipe moves outward, it drives the slider 3 to move outward together. At this time, the slider 3 moves outward and pushes the spring piece 5 connected to the limit block 2 and in contact with the clamping block 4 to bend outward. The function of the clamping block 4 is to provide a certain direction for the deformation of the spring piece 5, so that the spring piece 5 finally applies pressure to the inner wall of the pipe. As the pipe moves, the force applied by the spring piece 5 to the pipe also increases to prevent the pipe from falling off. When not installed, the disc spring 7 pulls the slider 3 to the initial position, and the outer shell 8 is used to protect the connection of the pipe from being damaged.
