Description

Technical Field

[0001] This application relates to the field of sealing connection technology, and specifically to a sealing gasket assembly. Background Technology

[0002] When two parts are connected, a washer and bolt are typically used. However, in situations where water or other liquids are frequently present around the connection, the liquid can seep through the contact surfaces between the washer and the connected parts, and between the washer and the bolt, causing corrosion or even damage to parts or electrical components requiring anti-corrosion properties. To prevent leakage, currently, a rubber gasket is usually placed under the washer, or sealant is applied around the washer and bolt, or welding or bonding is used directly. The first method only prevents leakage between the washer and the connected parts and cannot be used when water may submerge the washer. In addition, due to the soft contact connection, the bolt is prone to loosening over time, and the rubber gasket is partially exposed, making it susceptible to aging and damage. If the second method is used, each time disassembly is performed, the sealant must be cleaned, reassembled, and reapplied, which wastes a lot of time when there are many connection points. If the third method is used, only destructive disassembly can be used. Utility Model Content

[0003] The purpose of this application is to provide a sealing gasket assembly to solve the defects of existing technologies, such as poor waterproofing, insufficient strength, and low installation efficiency after bolt connection.

[0004] To achieve the above objectives, this application employs the following technical solution: This application discloses a sealing gasket assembly, characterized in that it includes fasteners, which fix and tighten a first connected part and a second connected part that are in contact with each other. The fastener and the first connected part are provided with a washer, the washer abuts against the flange of the fastener and the first connected part, and a sealing part is provided between the washer and the first connected part. The sealing part deforms under force to seal the contact surface between the fastener, the washer and the first connected part.

[0005] In a further embodiment of this application, the fastener is threadedly engaged to lock the first connected part and the second connected part, or the fastener passes through the first connected part and the second connected part and is engaged with a nut for locking.

[0006] In a further embodiment, when the fastener is threaded and locked, the fastener is a smooth cylinder near the head end and a threaded post away from the head, and the fastener is threadedly connected to the second connected part; when the fastener is locked with a nut, the portion of the fastener exposed above the second connected part is a threaded post.

[0007] In a further embodiment of this application, the sealing part includes a first sealing body and a second sealing body. The first sealing body is disposed between the bottom of the gasket and the first connected part, and the second sealing body is disposed between the hole wall of the gasket and the fastener.

[0008] In a further embodiment, the first sealing body and the second sealing body have the same structure. The first sealing body includes a first sealing ring, and the bottom of the gasket is provided with an annular groove, the depth of which is less than the thickness of the first sealing ring.

[0009] In a further embodiment of this application, the sealing part includes a third sealing body, which is disposed between the lower side of the hole wall of the washer through hole and the fastener.

[0010] In a further embodiment, the third sealing body includes a third sealing ring and a mounting groove. The mounting groove connects the hole wall and the bottom wall of the gasket. The third sealing ring is placed in the mounting groove, and the diameter of the mounting groove is smaller than the outer diameter of the third sealing ring, and the depth of the mounting groove is smaller than the thickness of the third sealing ring.

[0011] In a further embodiment of this application, the fastener is a bolt.

[0012] The beneficial effects of this application are as follows: In this application, a sealing part is added between the washer and the first connected part. When the fastener is locked and fixed to the first connected part and the second connected part, the sealing part deforms as the distance between the washer and the first connected part gradually approaches. At this time, the part in the sealing part that can perform the sealing function fills the gap between the two, ensuring the strict sealing of the contact surface between the washer and the first connected part. Compared with the design of fastener welding or gluing, this component ensures installation strength and sealing while having high assembly efficiency.

[0013] The sealing part is designed as a third sealing body. The mounting groove connects the hole wall and bottom wall of the gasket. At this time, the third sealing ring can directly seal the longitudinal and transverse gaps in the component. The design is simple, the use is efficient, and the manufacturing cost is reduced.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. Example 1

[0016] like Figure 1 As shown in the figure, this embodiment discloses a sealing gasket assembly, which includes a fastener 1, a first connected part 5 and a second connected part 6. The first connected part 5 and the second connected part 6 are stacked together, and the fastener 1 fixes and tightens the first connected part 5 and the second connected part 6. A gasket 2 is provided between the fastener 1 and the first connected part 5. After the first connected part 5 and the second connected part 6 are fixed, the gasket 2 abuts against the flange of the fastener 1 and the first connected part 5. A sealing part is provided between the gasket 2 and the first connected part 5. The sealing part deforms under force to seal the contact surface between the fastener 1, the gasket 2 and the first connected part 5. In the figure, this is the gap between the fastener 1 and the gasket 2 (longitudinal gap) and the gap between the first connected part 5 and the gasket 2 (transverse gap).

[0017] The sealing part in this embodiment includes a first sealing body and a second sealing body. The first sealing body is disposed between the bottom of the gasket 2 and the first connected part 5, and the second sealing body is disposed between the hole wall of the gasket 2 and the fastener 1. Usually, two sets of the first sealing body and the second sealing body are provided. This number basically meets the sealing strength of the component. During installation, the center lines of each sealing body are collinear.

[0018] In this embodiment, the first sealing body and the second sealing body have the same structure, but are arranged in different positions during installation. Taking the first sealing body as an example, the first sealing body includes a first sealing ring 3, wherein an annular groove is opened at the bottom of the gasket 2, and the first sealing ring 3 is placed in the annular groove. It should be noted that the groove depth of the annular groove is less than the thickness of the first sealing ring 3 to ensure that the gasket 2 can contact and compress the first sealing ring 3 during installation. Similarly, the second sealing ring 4 in the second sealing body is fixed to the annular groove on the wall of the through hole of the gasket 2. In the design, the outer diameter of the second sealing ring 4 is slightly larger than the maximum diameter of the corresponding annular groove, and the inner diameter of the second sealing ring 4 is slightly smaller than the outer diameter of the fastener.

[0019] In this embodiment, the fastener 1 is a bolt. In some structures that do not require disassembly, rivets can be used. When the fastener 1 is a bolt, the fastener 1 can directly lock the first connected part 5 and the second connected part 6 with a threaded engagement. At this time, the fastener 1 is a smooth cylinder near the head and a threaded column away from the head. The threaded end of the fastener 1 is engaged to connect the first connected part 5 and the second connected part 6.

[0020] In some embodiments, a nut is used in conjunction with fastener 1 for locking. In this case, the part of fastener 1 that exposes the second connected part 6 is a threaded post. The threaded post of fastener 1 passes through washer 2, first connected part 5 and second connected part 6, and the nut is tightened for fixation.

[0021] The key technology of this application lies in: The sealing gasket assembly consists of a gasket 2 and a highly elastic sealing ring. It utilizes the principle that the sealing ring is easily deformed under pressure to achieve sealing between the gasket and the parts, as well as between the gasket 2 and the fastener 1. Example 2

[0022] This embodiment provides a sealing gasket assembly. Compared to the previous embodiment, the sealing part is installed in a different position, achieving an unexpected effect. In this embodiment, the sealing part includes a third sealing body, which is disposed between the lower side of the hole wall of the gasket 2 and the fastener 1. The third sealing body provides sealing in both longitudinal and transverse directions. The third sealing body includes a third sealing ring 7 and a mounting groove. The mounting groove connects the hole wall and the bottom wall of the gasket 2. The third sealing ring 7 is placed in the mounting groove. It should be noted that the diameter of the mounting groove is smaller than the outer diameter of the third sealing ring 7, and the depth of the mounting groove is smaller than the thickness of the third sealing ring 7. The mounting groove can form an inside corner on the gasket 2. After the third sealing ring 7 is deformed under pressure, it can seal the gaps on both sides. The number of sealing rings in each position can be adjusted according to actual needs to improve waterproofing.

[0023] Specific usage: During use, tighten fastener 1 downwards, pressing it against washer 2. This causes the first sealing ring 3 at the bottom of washer 2 to deform under pressure, forming a seal between washer 2 and the first connected part 5. During installation, fastener 1 compresses the second sealing ring 4 at the hole of washer 2, creating a seal between fastener 1 and washer 2. To ensure a good seal, fastener 1 cannot be a fully threaded type; it must have a certain length of smooth shank. After installation, the second sealing ring 4 contacts the smooth shank of the bolt. This prevents water from seeping from between the first connected part 5 and fastener 1 onto the surface of the second connected part 6 when there is a large amount of water accumulation.
