Description

Technical Field

[0001] This utility model relates to the field of riveting bolt technology, and more specifically, to a leak-proof riveting bolt. Background Technology

[0002] A riveting bolt, comprising a mandrel, a rivet body, and a sleeve, is assembled by rotating the mandrel relative to the rivet body. The sleeve deforms due to resistance from the riveting components, and the deformed portion abuts against both sides of the riveting components along with the rivet body's blocking head. For example, patent application CN202111438897.2 describes an anti-loosening riveting bolt where the bolt shank extends beyond the outer wall of the other side, with the diameter being uniform throughout its length. A locking ring with a flange is fitted onto the extended end of the bolt shank, with the flange face tightly against the outer wall of the other side. The flange is deformed and formed by a riveting tool, engaging with the threads of the bolt shank and pressing firmly against the outer wall of the other side. A section of the bolt shank engaging with the locking ring has two opposing thread directions. The locking ring has an inward protrusion at the outer orifice where it engages with the bolt shank, the protrusion's height corresponding to the thread height. Theoretically, this can achieve a permanent lock-on design. This approach can increase the compressive force of the riveting, allowing for greater tensile load resistance for rivet bolts of the same shape, quality, and weight. It also allows for smaller dimensions, less material usage, lighter bolts, and lower costs. However, in this technical solution, the screw hole is often hexagonal for stability. This can prevent the screw and hole from fully engaging, potentially leading to leakage in components requiring tight fit. Utility Model Content

[0003] The main purpose of this utility model is to provide a leak-proof rivet bolt, which can effectively solve the problem in the background art where the screw hole is opened into a hexagonal shape for stability, and the screw and screw hole cannot fit fully. In this case, leakage may occur when it is installed on devices that require tightness.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a leak-proof riveting bolt, including a screw head, a screw barrel installed on the lower end surface of the screw head, a first screw rod engaged inside the screw barrel, and a sealing component provided on the screw head.

[0005] Preferably, a sealing gasket is provided on the lower surface of the screw head.

[0006] Preferably, the screw barrel has several equidistant limiting grooves on its circumferential surface.

[0007] Preferably, the sealing assembly includes a sealing retaining ring, a mounting groove, and a guide groove. The sealing retaining ring is slidably mounted through the middle of the screw head, the mounting groove is formed on the upper surface of the screw head, and the guide groove is formed on the circumferential surface of the screw head.

[0008] Preferably, a sealing ring is fixedly installed on the lower surface of the sealing ring.

[0009] Preferably, a guide rod is fixedly installed on the circumferential surface of the sealing ring, and the guide rod is slidably installed inside the guide groove.

[0010] Preferably, a second screw is fitted inside the mounting groove, and the lower end of the second screw is rotatably mounted on the upper surface of the guide rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] (1) By rotating the second screw, the second screw can be moved up or down, which in turn drives the guide rod to move inside the guide groove, and drives the sealing ring to move inside the screw head, so that the sealing ring is completely set inside the screw hole, making this device applicable to screw holes of different depths. At this time, the sealing ring is flipped so that the sealing ring is attached to the lower surface of the screw hole. At this time, the operator uses tools to deform the screw barrel, so that the lower surface of the screw barrel is deformed, and the lower surface of the screw barrel is tightly attached to the lower surface of the device to be connected. At this time, the sealing ring is set at the contact point between the screw barrel and the lower surface of the device. After the device is installed, the sealing gasket and sealing ring will be set on the upper and lower surfaces of the device respectively, and the sealing ring will be set inside the screw hole, filling the screw hole. After the device is installed, a triple seal will be applied to the device to ensure the sealing performance of the device and prevent leakage. Attached Figure Description

[0018] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0019] like Figure 1 As shown, a leak-proof rivet bolt includes a screw head 1, a screw barrel 5 is mounted on the lower surface of the screw head 1, a first screw 6 is engaged inside the screw barrel 5, and a sealing component 3 is provided on the screw head 1.

[0020] like Figure 1 As shown, a sealing gasket 2 is provided on the lower surface of the screw head 1, and several limiting grooves 4 are equally spaced on the circumference of the screw barrel 5. By providing the sealing gasket 2, the sealing performance between the screw head 1 and the device can be strengthened.

[0021] like Figure 2 , 3 As shown in Figure 4, the sealing assembly 3 includes a sealing ring 301, a mounting groove 303, and a guide groove 305. The sealing ring 301 is slidably mounted through the middle of the screw head 1. The mounting groove 303 is formed on the upper surface of the screw head 1, and the guide groove 305 is formed on the circumferential surface of the screw head 1. A sealing ring 302 is fixedly mounted on the lower end surface of the sealing ring 301, and a guide rod 306 is fixedly mounted on the circumferential surface of the sealing ring 301. The guide rod 306 is slidably mounted inside the guide groove 305. A second screw 304 is meshed and mounted inside the mounting groove 303. The lower end of the second screw 304 is rotatably mounted on the upper surface of the guide rod 306. By rotating the second screw 304, the second screw 304 moves upward or downward, which in turn drives the guide rod 306 to move within the guide groove 305, thereby driving the screw head 1. The dynamic sealing ring 301 moves inside the screw head 1, completely setting the sealing ring 301 inside the screw hole, allowing this device to be used in screw holes of different depths. At this time, the sealing ring 302 is flipped so that it fits against the lower surface of the screw hole. Then, the operator uses tools to deform the screw barrel 5, deforming the lower surface of the screw barrel 5 so that the lower surface of the screw barrel 5 fits tightly against the lower surface of the device to be connected. At this time, the sealing ring 302 is placed at the contact point between the screw barrel 5 and the lower surface of the device. After the device is installed, the sealing gasket 2 and the sealing ring 302 are respectively placed on the upper and lower surfaces of the device, and the sealing ring 301 is placed inside the screw hole, filling the screw hole completely. After the device is installed, a triple seal is applied to ensure the sealing performance of the device and prevent leakage.

[0022] The working principle of this type of leak-proof rivet bolt:

[0023] When using this device for riveting, first, the screw barrel 5 is fitted into the pre-drilled screw hole. The sealing ring 301 is slidably mounted through the middle of the screw head 1. The mounting groove 303 is located on the upper surface of the screw head 1, and the guide groove 305 is located on the circumference of the screw head 1. A sealing ring 302 is fixedly mounted on the lower surface of the sealing ring 301, and a guide rod 306 is fixedly mounted on the circumference of the sealing ring 301. The guide rod 306 is slidably mounted inside the guide groove 305. A second screw 304 is fitted and engaged inside the mounting groove 303. The lower end of the second screw 304 is rotatably mounted on the upper surface of the guide rod 306. By rotating the second screw 304, it moves upward or downward, simultaneously driving the guide rod 306 to move within the guide groove 305. This allows the sealing ring 301 to move inside the screw head 1, completely setting it inside the screw hole. This enables the device to be used in screw holes of different depths. The sealing ring 302 is then flipped so it adheres to the lower surface of the screw hole. The operator then uses tools to deform the screw cylinder 5, deforming its lower surface so it tightly adheres to the lower surface of the device to be connected. The sealing ring 302 is then positioned at the contact point between the screw cylinder 5 and the lower surface of the device. After installation, the sealing gasket 2 and sealing ring 302 are respectively placed on the upper and lower surfaces of the device, and the sealing ring 301 is placed inside the screw hole, filling it completely. This triple sealing ensures the device's sealing performance and prevents leakage.

[0024] The above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
