Description

Technical Field

[0001] This utility model relates to the field of sealing element skeletons, and more specifically, it relates to an assembled sealing element skeleton. Background Technology

[0002] The racetrack-shaped sealing skeleton is an irregularly shaped sealing support structure designed specifically to adapt to non-circular contact surfaces. Its geometric features are two semi-circular arcs at both ends and a straight plate in the middle, which are smoothly connected. It combines the sealing fit of the circular ends with the rigid support of the straight plate section. It is widely used in sealing systems of new energy vehicle motors, industrial valves and medical equipment, and has become a key component that balances sealing reliability and total life cycle cost under complex working conditions.

[0003] However, traditional runway-shaped sealing skeletons are mostly made of metal stamping or engineering plastic injection molding. While they have strong overall structure, they lack the design for disassembly or partial replacement. Since damaged parts cannot be repaired individually, the entire sealing assembly must be scrapped, which significantly increases the cost of use. In addition, the one-piece molding process makes the shape of the sealing skeleton fixed and cannot be adjusted for applicability, resulting in poor practicality.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes an assembled sealing element skeleton. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an assembled sealing component skeleton.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an assembled sealing skeleton, which is a racetrack-shaped skeleton, including two separate and symmetrically designed skeleton arc edges that constitute the arc part of the racetrack-shaped skeleton, and the two skeleton arc edges are connected by an insertable telescopic component. The insertable telescopic component constitutes the transverse connection part between the arc parts of the racetrack-shaped skeleton, and is segmentedly fixed by the fixing structure on the insertable telescopic component.

[0007] Preferably, the insertable telescopic component includes a rod A that is fixed to one side of the arc-shaped connecting surface of one of the skeletons and has an opening and is hollow inside, and a rod B that is fixed to the arc-shaped connecting surface of the other skeleton and can be inserted into the rod A.

[0008] Preferably, the fixing structure includes a through hole A on the surface of rod A near the opening, and multiple through holes B arranged in a horizontal array on the surface of rod B. A screw is inserted into the through holes A and B, and a circular baffle is fixedly connected to one end of the screw, and a nut is threaded to the other end.

[0009] Preferably, a circular groove A is provided on the contact surface between the rod body A and the circular baffle for the circular baffle to be inserted.

[0010] Preferably, a circular groove B is provided on the contact surface between the rod body A and the nut, and an elastic air cushion is bonded inside the circular groove B.

[0011] Preferably, a connecting component for maintaining the linear movement of the screw is installed on the rod body A.

[0012] Preferably, the connecting component includes a connecting shell fixed to the rod body A, and an inner block is slidably connected inside the connecting shell, and a connecting rod is fixedly connected to the surface of the inner block. The surface of the connecting shell is provided with a through hole C for the connecting rod to pass through, and the head of the connecting rod is connected to a circular baffle through a connecting plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This utility model assembles two curved edges of the skeleton by connecting them through an insertable telescopic component. Then, a fixing structure is used to fix them at preset segmented positions on the insertable telescopic component. This allows for adaptability adjustment of the shape of the sealing skeleton, improving its practicality. In case of damage, the fixing structure can be released, and the two curved edges of the skeleton can be disassembled. Thus, after local wear, only the corresponding curved part needs to be replaced, without the need for complete scrapping. This solves the problems of shape inapplicability adjustment and high overall replacement cost in the prior art.

[0015] 2. When the nut is installed, the elastic air cushion will be squeezed. The elastic restoring force stored in its internal honeycomb structure will continuously exert a reverse force on the nut, thereby preventing the nut from loosening.

[0016] 3. This utility model can maintain the linear movement of the screw relative to the rod A, which facilitates its insertion operation. At the same time, the connecting component can also ensure that the screw and its components will not detach from the rod A, thus avoiding loss. Attached Figure Description

[0024] like Figure 1-5 As shown, this utility model provides an assembled sealing skeleton, which is a racetrack-shaped skeleton, including two separate and symmetrically designed skeleton arc edges 1 that constitute the arc part of the racetrack-shaped skeleton. The two skeleton arc edges 1 are connected by an insertable telescopic component 2. The insertable telescopic component 2 constitutes the lateral connection part between the arc parts of the racetrack-shaped skeleton, and is segmentedly fixed by the fixing structure 3 on the insertable telescopic component 2.

[0025] In use, the two curved edges 1 of the skeleton are assembled by connecting them through the insertable telescopic component 2. Then, the fixed structure 3 fixes them at the preset segmented positions of the insertable telescopic component 2 (that is, the distance between the transverse connecting parts of the runway-shaped skeleton can be adjusted as needed) to make adaptability adjustments to the shape of the sealing skeleton and improve its practicality. At the same time, in case of damage, the relevant fixation of the fixed structure 3 can be released, and the two curved edges 1 of the skeleton can be disassembled. In this way, after local wear, only the corresponding curved part needs to be replaced, without the whole skeleton being scrapped.

[0026] Furthermore, this utility model also provides detailed structures of the insertable telescopic component 2 and the fixing structure 3: The insertable telescopic component 2 includes a rod A201 fixed to one side of the connecting surface of one of the frame arc-shaped edges 1 with an opening and a hollow interior, and a rod B202 fixed to the connecting surface of the other frame arc-shaped edge 1 and capable of being inserted into the rod A201. The fixing structure 3 includes a through hole A301 on the surface of the rod A201 near the opening, and a plurality of through holes B302 arranged in a horizontal array on the surface of the rod B202. A screw 303 is inserted into the through holes A301 and B302, and a circular baffle 304 is fixedly connected to one end of the screw 303, and a nut 305 is threadedly connected to the other end.

[0027] When assembling the two curved edges 1 of the skeleton, insert the rod B202 on one curved edge 1 into the rod A201 on the other curved edge 1. Then, pull the two curved edges 1 to move them relative to each other, thereby aligning the through hole A301 on the rod with the different through holes B302 on the rod B202 to adjust the distance between the two curved edges 1. Afterward, pass the screw 303 on the circular baffle 304 through the through holes B302 and A301. This allows the circular baffle 304 to abut against one side of the rod A201. Then, a nut 305 is installed on the screw 303. The nut 305 moves along the screw 303 and slowly abuts against the other side of the rod A201, thus assembling the racetrack-shaped frame. Similarly, the nut 305 is removed, the screw 303 is pulled out from the through hole B302 and the through hole A301, and the rod B202 is pulled out from the rod A201, thus completing the disassembly of the two frame arc plates.

[0028] Furthermore, a circular groove A4 is provided on the contact surface between the rod body A201 and the circular baffle 304 for the circular baffle 304 to be inserted, thereby reducing the space occupied by the circular baffle 304 during installation. A circular groove B5 is provided on the contact surface between the rod body A201 and the nut 305, and an elastic air cushion 6 is bonded inside the circular groove B5. When the nut 305 is installed, it will compress the elastic air cushion 6, and the elastic restoring force stored in its internal honeycomb structure will continuously exert a reverse force on the nut 305, thereby preventing the nut 305 from loosening.

[0029] Furthermore, a connecting component 7 for maintaining the linear movement of the screw 303 is installed on the rod body A201. The connecting component 7 includes a connecting shell 701 fixed on the rod body A201, and an inner block 702 is slidably connected inside the connecting shell 701. A connecting rod 703 is fixedly connected to the surface of the inner block 702. A through hole C704 is opened on the surface of the connecting shell 701 for the connecting rod 703 to pass through. The head of the connecting rod 703 is connected to the circular baffle 304 through the connecting plate 705.

[0030] When the screw 303 is inserted into or pulled out of the through hole B302, the screw 303 will drive the connecting plate 705 to move the connecting rod 703. The connecting rod 703 moves along the through hole C704, and at the same time, the connecting rod 703 drives the inner block 702 to move. It should be noted that the cross-section of the inner block 702 is the same as the internal cross-section of the connecting shell 701. It can only move in a straight line along the inside of the connecting shell 701, thereby maintaining the straight line movement of the screw 303 relative to the rod body A201, which facilitates its insertion operation (no further alignment operation with the through hole A301 is required). At the same time, the connecting component 7 can also ensure that the screw 303 and its components will not detach from the rod body A201, avoiding the occurrence of loss.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
