Description

Technical Field

[0001] This utility model relates to the field of bolt technology, specifically to a waterproof bolt. Background Technology

[0002] In modern industrial manufacturing and construction engineering, bolts are used as key fasteners in the assembly and connection of various equipment and structures.

[0003] Especially in applications such as ceilings, roofs, ship decks, electronic device housings, and outdoor billboards, the waterproof performance of bolts is of extremely high demand, and traditional bolts have obvious defects in practical use. Taking ceiling fixing as an example, it is difficult to achieve a perfect seal between the bolt and the connection hole, and rainwater or liquids can easily seep in through the gaps, causing leakage.

[0004] Therefore, a waterproof bolt is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a waterproof bolt in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A waterproof bolt includes a bolt body, wherein a water-stop ring is fixedly installed at the bottom end of the bolt head bearing ring of the bolt body, and the water-stop ring and the outer surface of the bolt shank form an installation groove, and a waterproof sealing component is sleeved in the installation groove.

[0008] Furthermore, the bolt body is composed of a bolt shank, a bolt head bearing ring, and a bolt hexagonal head, wherein the bolt head bearing ring is fixedly installed at the end of the bolt shank, and the bolt hexagonal head is fixedly installed at the top of the bolt head bearing ring.

[0009] Furthermore, the inner wall of the water-stop ring is provided with multiple sets of wedge-shaped grooves for positioning the waterproof sealing assembly.

[0010] Furthermore, the waterproof sealing assembly includes a rubber ring inserted into the mounting groove, a rubber ring disposed inside the rubber ring, and an elastic sealing ring fixedly connected to the bottom surface of the rubber ring, so as to seal the gap on the surface of the bolt head bearing ring connector through the rubber ring and the elastic sealing ring.

[0011] Furthermore, the cross-section of the rubber ring is U-shaped, and the rubber ring is disposed inside the rubber ring.

[0012] Furthermore, a wedge is fixedly installed on the outer surface of the rubber ring, and when the rubber ring is inserted into the mounting groove, the wedge engages with the wedge groove.

[0013] The beneficial effects of this utility model are as follows:

[0014] The basic fastening function is achieved through the bearing ring on the bolt head. The water-stop ring is installed at the bottom of the bearing ring on the bolt head. The waterproof sealing component is embedded in the installation groove. Utilizing its elastic deformation and sealing performance, it fills the tiny gaps between the bolt body and the connecting hole and the surface of the mounting part, effectively preventing liquid from seeping in, thereby achieving a waterproof effect.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0023] It should be noted that similar reference numerals and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] In the description of the embodiments of this utility model, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] like Figures 1 to 5 As shown, a waterproof bolt includes a bolt body; as Figure 1 , Figure 2 and Figure 3 As shown, the bolt body consists of a bolt shank 1, a bolt head bearing ring 2, and a bolt hexagonal head 3. The bolt head bearing ring 2 is fixedly installed at the end of the bolt shank 1, and the bolt hexagonal head 3 is fixedly installed at the top of the bolt head bearing ring 2.

[0026] More specifically, the bolt shank 1 is used to pass through the connecting hole and connect the nut to form a fixed structure, while the bolt head bearing ring 2 and the bolt hexagonal head 3 provide a larger contact area and allow for rotation.

[0027] A water-stop ring 4 is fixedly installed at the bottom end of the bolt head bearing ring 2. The water-stop ring 4 and the outer surface of the bolt shank 1 form an installation groove 6, and a waterproof sealing component is fitted inside the installation groove 6; such as Figure 3 , Figure 4 and Figure 5 As shown, specifically, the waterproof sealing assembly includes a rubber ring 7 inserted into the mounting groove 6, a rubber ring 9 disposed inside the rubber ring 7, and an elastic sealing ring 10 fixedly connected to the bottom surface of the rubber ring 9, so that the rubber ring 9 and the elastic sealing ring 10 are used to seal the gap on the surface of the bolt head bearing ring 2 connector.

[0028] More specifically, the structural design of the rubber ring 9 and the elastic sealing ring 10 allows them to fit tightly against the surfaces of the bolt body and the connecting hole, effectively sealing the gap between the bolt body and the surface of the connector, preventing liquid from seeping in, and achieving a highly efficient waterproof function.

[0029] like Figure 3 As shown, in some practical applications, the inner wall of the water-stop ring 4 is provided with multiple sets of wedge-shaped grooves 5 for positioning the waterproof sealing components.

[0030] More specifically, when the waterproof sealing component is inserted into the water-stop ring 4, the wedge groove 5 can guide and fix the waterproof sealing component, ensuring that the waterproof sealing component will not be displaced during the tightening of the bolt body.

[0031] In some practical applications, a wedge block 8 is fixedly installed on the outer surface of the rubber ring 7. When the rubber ring 7 is inserted into the mounting groove 6, its wedge block 8 is engaged with the wedge groove 5.

[0032] More specifically, when the rubber ring 7 is inserted into the mounting groove 6, the wedge block 8 is precisely engaged with the wedge-shaped groove 5 on the surface of the water-stop ring 4, which can prevent the rubber ring 7 from shifting during installation.

[0033] like Figure 5 As shown, specifically, the cross-section of the rubber ring 7 is U-shaped, and the rubber ring 9 is disposed inside the rubber ring 7.

[0034] More specifically, the U-shaped rubber ring 7 causes the rubber ring 9 to expand outward when it is compressed, thus limiting its movement.

[0035] In summary: The basic fastening function is achieved through the bolt head bearing ring 2, the water-stop ring 4 is installed at the bottom of the bolt head bearing ring 2 on the bolt body, and the waterproof sealing component is embedded in the installation groove 6. Utilizing its elastic deformation and sealing performance, it fills the tiny gaps between the bolt body and the connecting hole and the surface of the mounting part, effectively preventing liquid from seeping in, thereby achieving a waterproof effect.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
