Description

Technical Field

[0001] This utility model relates to the field of sealing technology, and in particular to a sealing component. Background Technology

[0002] In industries such as aerospace, automotive manufacturing, and machining, riveting and screwing are common connection methods. These methods are typically used to securely connect two or more components together. After riveting or screwing, to prevent moisture, dust, and other harmful substances from entering the connection area, the exposed ends of the screws, nuts, or rivets are usually sealed. The main purpose of this process is to improve the sealing of the connection, extend the service life of the joint, and ensure the reliability of the overall structure.

[0003] Existing sealing methods typically involve applying sealant directly to the exposed ends of screws or rivets. However, this traditional method has significant limitations and drawbacks. First, the sealant application is often unsatisfactory. Due to the operator's skill level and the operating environment, the sealant may be applied unevenly, resulting in poor sealing. Second, traditional methods are prone to misalignment during application, meaning the sealant may not accurately cover the exposed parts of the screw or rivet, further degrading the sealing performance. While the aforementioned sealing techniques address the sealing problem at joints to some extent, their effectiveness, accuracy, and efficiency are all significantly lacking. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a sealing component that can improve the sealing effect, reduce positional offset, and improve the efficiency and reliability of the overall sealing process.

[0005] Technical solution: A sealing assembly includes a positioning frame, a positioning cap, and a sealing cap; the positioning frame has a circular through hole in its center; the positioning cap includes a circular barrel cover with an open bottom and a handle on the top of the barrel cover, the outer diameter of the barrel cover being slightly smaller than the diameter of the through hole; the sealing cap includes a bell-shaped cap body with an opening facing downwards, the top of the cap body is provided with a tail rod, and the diameter of the lower opening of the cap body is slightly smaller than the diameter of the through hole.

[0006] Furthermore, it is particularly preferred that the thickness of the lower edge of the cap gradually tapers into a thin blade shape.

[0007] Furthermore, it is particularly preferred that the inner wall of the cap is polished, with a surface roughness Ra of 0.01-0.1 μm.

[0008] Furthermore, it is particularly preferred that the top of the tail rod of the sealing cap is formed with a plug in the form of an inverted triangular rotating body.

[0009] Furthermore, it is particularly preferred that the barrel cover has a double-layer structure with multiple reinforcing ribs arranged circumferentially between the layers.

[0010] Furthermore, it is particularly preferred that the positioning frame is a rectangular frame structure, which includes a rectangular bottom surface and four side surfaces disposed around the rectangular bottom surface and perpendicular to it, and ribs are formed between the side surfaces and the bottom surface.

[0011] Furthermore, it is particularly preferred that the upper part of the through hole is machined into an inner chamfer.

[0012] Furthermore, it is particularly preferred that the top of the rectangular bottom surface of the positioning frame has a raised model mark, and the barrel cover of the positioning cap and the cap body of the sealing cap have raised model marks.

[0013] This invention uses a positioning cap to align the center of a hexagonal nut or rivet, then uses a positioning frame to fix the position of the positioning cap, and finally uses a sealing cap to fill with glue and place it in the positioning frame, thereby achieving a seal on the part. The use of the positioning frame, positioning cap, and sealing cap together makes the sealing position more accurate.

[0014] Furthermore, after sealing, the glue is cut along the lower edge of the sealing cap to evenly separate any excess glue residue.

[0015] In addition, the positioning frame has a bottom and sides. When the positioning frame is removed after the sealant has cured, excess sealant residue can be taken away directly, which improves the efficiency of subsequent sealant cleaning.

[0016] By adding an inverted triangular rotating plug to the top of the end cap, it is easier to remove during the descaling process after the sealant has cured. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0024] like Figure 2-4 The sealing assembly shown specifically includes a positioning frame 1, a positioning cap 2, and a sealing cap 3. The positioning frame 1 has a circular through-hole 13 at its center. The positioning cap 2 includes a circular barrel cover 21 with an open bottom and a handle 22 on top of the barrel cover 21. The outer diameter of the barrel cover 21 is slightly smaller than the diameter of the through-hole 13. The sealing cap 3 includes a bell-shaped cap body 31 with an opening facing downwards. A tail rod 32 is provided at the top of the cap body 31. The diameter of the lower opening of the cap body 31 is slightly smaller than the diameter of the through-hole 13. The sealing cap 3 is shaped like an inverted goblet.

[0025] The operator first uses the locating cap 2 to locate the center of the hexagonal nut or rivet, then uses the locating frame 1 to fix the position of the locating cap 2. Next, the locating cap 2 is removed, and after applying sealant with the sealing cap 3, it is placed in the locating frame 1. Once the sealant has cured, it is removed, thus achieving a seal on the part. Figure 5 The cured colloid b and nut a are shown after encapsulation.

[0026] Based on the usage environment of the parts, the positioning frame 1 is made of transparent PP (polypropylene) material, which facilitates observation of whether the sealant has overflowed onto the skin surface. PP has a density of 0.91 g / cm3 and is characterized by its lightweight, good heat resistance, high flexural fatigue life, high melting point and tensile strength, and resistance to chemicals and fatigue. The positioning cap is made of natural-colored PE (polyethylene) material, with a density of 0.94 g / cm3. PE is characterized by its translucency, softness, non-toxicity, low cost, and ease of processing, and has good chemical resistance. Since the sealing cap requires good toughness and easy removal during use, and PE material has a high melting point, tensile strength, and resistance to chemicals and fatigue, the sealing cap is made of PE (polyethylene), with red masterbatch added to make it more conspicuous and easy to distinguish from the positioning cap.

[0027] Based on the actual use of the sealing cap 3 and the problems encountered in actual operation, the design of the sealing cap 3 parts has been optimized. An inverted triangular rotating plug 321 has been added to the top of the tail rod 32 of the sealing cap 3, making it easier to remove during the degumming process after the sealant has cured.

[0028] The positioning frame 1 has a rectangular frame structure, including a rectangular base 11 and four sides 12 perpendicular to the rectangular base 11. Ribs 4 are formed between the sides 12 and the base 11 to enhance structural strength. The upper part of the through hole 13 of the positioning frame 1 is machined into an inner chamfer to facilitate the insertion of the sealing cap 3. Acrylic double-sided tape is applied to the bottom of the positioning frame 1, and the tape can be removed without leaving any residue. The top of the rectangular base 11 of the positioning frame 1 has a raised model number 6, and the barrel cover 21 of the positioning cap 2 and the cap body 31 of the sealing cap 3 also have raised model number 6 for easy and quick identification of different models.

[0029] The barrel cover 21 of the positioning cap 2 has a double-layer structure, with multiple reinforcing ribs 5 arranged circumferentially between the layers. The inner hole is reinforced with ribs, making it less prone to deformation and reusable.

[0030] like Figure 1 As shown, the lower edge of the cap 31 gradually tapers into a thin blade shape, which can effectively smooth and divide excess adhesive. To prevent the adhesive from adhering to the inner wall of the cap 31, the inner wall of the cap 31 is polished to a high gloss, preferably with a surface roughness Ra of 0.01-0.1 μm.

[0031] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the inventive concept, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
