Description

Technical Field

[0001] This utility model relates to the field of pipeline positioning technology, specifically to a positioning fixture for pipeline coiling and shaping. Background Technology

[0002] In the fields of medical aesthetics and clinical treatment, blood purification technology has been widely used to improve conditions such as abnormal lipid metabolism. Among them, treatments such as liposuction achieve therapeutic effects by filtering excess fat from the blood. In this process, the blood needs to be purified through an external circuit before being returned to the body. Maintaining a stable temperature during blood return is a key step in ensuring treatment comfort and safety.

[0003] The normal human body temperature is maintained at around 37°C. When blood leaves the circulatory system and enters the extracorporeal circuit, it is easily subject to heat loss due to the influence of ambient temperature, causing the blood temperature to drop. If this cooled blood is directly reinfused into the body, the patient will experience significant cold discomfort, and it may even trigger adverse reactions such as vasoconstriction and chills, affecting the treatment experience and progress. To solve this problem, the industry currently widely uses a heating plate to regulate the temperature of the blood in the extracorporeal circuit. By guiding the blood through the tubing in contact with the heating plate, the blood temperature is maintained at around 37°C, close to the human body temperature, thus reducing discomfort during reinfusion.

[0004] However, the tubing used in blood purification circuits needs to be designed with a specific coiled shape according to the layout of the treatment equipment and ergonomic requirements. Especially when used with a heating plate, the tubing needs to fit tightly against the heating surface to ensure heat exchange efficiency, while maintaining a stable coiled structure to avoid abnormal flow caused by tubing bending or displacement. Existing tubing coiling and shaping techniques have several problems: First, the tubing is very prone to loosening after normal coiling but before being fixed. To prevent loosening, manual glue application is required while coiling, making the process cumbersome. Second, the coil shape is inconsistent. Due to manual operation, the size of the coil varies greatly depending on the technique and tightness, making it difficult to ensure precise contact between the tubing and the heating plate, thus affecting temperature control. Third, manual operation results in extremely low output and efficiency, and the process is difficult, failing to meet the needs of large-scale production.

[0005] Therefore, the technical problem to be solved in this application is to develop a positioning fixture that can accurately control the curling shape of the pipeline, ensure the stability of the shaping, and be compatible with various pipeline specifications. Utility Model Content

[0006] To address the problems existing in current shield-shaped shaping ovens, this utility model provides a positioning fixture for pipe curling and shaping.

[0007] The technical solution adopted by this utility model to solve its technical problem is: a positioning fixture for coiling and shaping pipelines, including a base plate and a limiting frame; the base plate has a placement station for placing pipelines, and the base plate is provided with detachable limiting blocks on the four sides corresponding to the placement station. The limiting blocks have an arc-shaped groove for cooperating with the pipeline on the side facing the placement station; the limiting frame is disposed on the upper side of the placement station and is detachably connected to the base plate, and the limiting frame is provided with a pressure strip corresponding to each limiting block. The pressure strip extends to the upper side of the limiting block and is used to press against the pipeline placed at the placement station.

[0008] The placement station is equipped with a spiral groove structure, which is used to clamp the disc-shaped structure formed after the pipe is wound. The groove width of the spiral groove structure is adapted to the outer diameter of the pipe.

[0009] The limiting block is slidably mounted on the base plate.

[0010] The limiting frame is a metal frame.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. The placement station on the base plate provides a clear placement reference for the pipeline. Combined with the four removable limiting blocks, the arc-shaped grooves on the side of the limiting blocks facing the placement station can fit against the outer wall of the pipeline, reliably limiting the pipeline from the side and preventing lateral displacement during the shaping process. This, along with the pressure strips on the limiting frame, forms a double limiting effect, ensuring that the pipeline can be rolled and shaped strictly according to the preset form.

[0013] 2. Because the limiting block adopts a detachable design and its position on the base plate can be adjusted according to actual needs, the fixture can be adapted to pipes with different diameters and different coiling parameters. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the positioning fixture for pipe coiling and shaping in the embodiments of this application. Detailed Implementation

[0015] The present application will be further described in detail below with reference to the accompanying drawings, so that those skilled in the art can better understand and implement the present invention, but the embodiments described are not intended to limit the present invention.

[0016] Example 1: As Figure 1 As shown, a positioning fixture for coiling and shaping pipelines includes a base plate 1 and a limiting frame 2.

[0017] The base plate 1 has a placement station 3 for placing pipes. The size and shape of the placement station 3 are designed according to the actual pipe dimensions and winding requirements. In this embodiment, the placement station 3 is provided with a spiral groove structure 4, which is used to hold the disc-shaped structure formed after the pipe is wound. The groove width of the spiral groove structure 4 is adapted to the outer diameter of the pipe, so that when the pipe is wound into a disc shape, it can be precisely held in the spiral groove structure 4, effectively preventing the pipe from shifting during the shaping process and ensuring the shaping effect.

[0018] On the base plate 1, detachable limiting blocks 5 are respectively provided on the four sides corresponding to the placement station 3. The limiting blocks 5 are made of engineering plastic, which is lightweight and has a certain degree of wear resistance. The side of the limiting block 5 facing the placement station 3 has an arc-shaped groove 6 for matching with the pipeline. The curvature of the arc-shaped groove 6 is adapted to the outer circumference curvature of the pipeline, so that the limiting block 5 can better fit with the pipeline and play a limiting role for the pipeline.

[0019] The limiting block 5 is slidably mounted on the base plate 1. Specifically, the base plate 1 has a corresponding groove for the limiting block 5, and the bottom end of the limiting block 5 slides into the groove, thus forming a sliding fit with the base plate 1. This sliding fit between the limiting block 5 and the base plate 1 allows the position of the limiting block 5 on the base plate 1 to be adjusted according to the actual size and curling position of the pipeline, improving the versatility of the fixture. Simultaneously, the limiting block 5 and the base plate 1 are detachably connected by bolts 8. After the limiting block 5 is adjusted to the appropriate position, it is fixed to the base plate 1 by bolts 8, ensuring that the limiting block 5 will not move during the pipeline shaping process.

[0020] The limiting frame 2 is located on the upper side of the placement station 3 and is detachably connected to the base plate 1. In this embodiment, the limiting frame 2 is a metal frame, and the limiting frame 2 and the base plate 1 are detachably connected by bolts.

[0021] Each limiting bracket 2 has a pressure strip 9 corresponding to each limiting block 5. The pressure strip 9 is made of elastic metal material and has a certain elastic deformation capability. The pressure strip 9 extends to the upper side of the limiting block 5 and is used to press against the pipeline installed at the placement station 3. An elastic buffer layer 11 is provided on the side of the pressure strip 9 facing the pipeline. The elastic buffer layer 11 is made of silicone material and can play a buffering role when the pressure strip 9 presses against the pipeline, so as to avoid damage to the pipeline by the pressure strip 9.

[0022] Example 2: A permanent magnet is embedded inside the limiting block 5, which is used to magnetically attract and cooperate with the limiting frame 2.

[0023] Example 3: An electromagnet is embedded inside the limiting block 5, which is used to engage with the limiting frame 2 through magnetic attraction.

[0024] In use, the positioning fixture for pipe coiling and shaping according to the present invention first adjusts the position of the limiting block 5 on the base plate 1 according to the pipe size and coiling requirements, and fixes it with bolts 8. Then, the pipe is wound into a disc shape and inserted into the spiral groove structure 4 of the placement station 3. Next, the limiting frame 2 is installed on the base plate 1 with bolts, so that the pressure strip 9 extends to the upper side of the limiting block 5 and presses against the pipe. Finally, the exposed part of the pipe is glued and shaped.

[0025] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
