[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0020] Depend on Figure 1 , Figure 2 and Figure 3 This invention discloses an anti-vibration bolt for an oil pipeline shaft with a limiting and fixing function. A bolt head 101 is fixedly connected to the top of the bolt shank 100, facilitating rotation of the bolt shank 100 via the bolt head 101. A washer 102 is slidably connected to the outer wall of the bolt shank 100, supporting an anti-slip plate 103. The bottom wall of the washer 102 has evenly spaced lifting grooves, and the inner wall of the lifting grooves is slidably connected to the anti-slip plate 103, which abuts against the surface of the component for anti-slip purposes. The bottom wall of the bolt head 101 is uniformly fixed with anti-slip protrusions, which can increase friction. The upper side of the outer wall of the bolt head 101 is hexagonal, and the lower side of the outer wall of the bolt head 101 is provided with a threaded groove. A push ring 104 is screwed to the lower side of the outer wall of the bolt head 101. The push ring 104 facilitates the movement of the push rod 105. The top wall of the anti-slip plate 103 is fixedly connected with the push rod 105. The push rod 105 facilitates the movement of the anti-slip plate 103. The top of the push rod 105 penetrates the top wall of the gasket 102.
[0021] In this embodiment: the bolt head 101 is tightened by connecting a wrench, which drives the bolt rod 100 to rotate. The bolt rod 100 is screwed to a designated position for easy installation and positioning of the pipeline. The bolt rod 100 moves within the mounting hole, causing the bolt head 101 to move. The bolt head 101 then moves the washer 102, pushing it onto the surface of the oil pipe component. Another wrench rotates the push ring 104, which moves on the bolt head 101. The push ring 104 pushes the push rod 105, which in turn pushes the anti-slip plate 103, ensuring it adheres tightly to the component surface for anti-slip. The anti-slip protrusions enhance anti-slip properties, facilitating tightening and anti-slip installation by pushing against the anti-slip plate 103. This prevents the bolt rod 100 from deflecting due to vibration and avoids damage caused by friction between the anti-slip plate 103 and the component during tightening.
[0022] The bottom wall of the bolt head 101 is evenly provided with sliding grooves, and the top wall of the washer 102 is evenly slidably connected with a sliding rod 106. The sliding rod 106 facilitates the movement of the anti-slip plate 103. The sliding rod 106 is located in the inner cavity of the sliding groove.
[0023] In this embodiment: the anti-slip plate 103 facilitates the limiting of the pad 102, the pad 102 facilitates the limiting of the slide rod 106, the slide rod 106 limits the limiting of the bolt head 101, and the bolt head 101 facilitates the limiting of the bolt rod 100. This allows the device to easily limit the bolt rod 100, preventing the bolt rod 100 from deflecting, which is beneficial to improving the vibration resistance.
[0024] Push springs 107 are fixedly connected to the top wall of the inner cavity of the slide. The push springs 107 facilitate the pushing of the slide rod 106. The bottom end of the push spring 107 is located at the top end of the slide rod 106.
[0025] In this embodiment: the push spring 107 facilitates the push of the slide rod 106, and the slide rod 106 pushes the washer 102, so that the washer 102 is tightly pressed against the component. At the same time, a counter-working force is provided to push the bolt head 101. The bolt head 101 facilitates the push and pull of the bolt rod 100, so that the bolt rod 100 is pressed against the connecting thread groove, which facilitates the push and limit of the bolt rod 100. This makes it easy for the device to apply the pushing force, so that the bolt rod 100 is tightly screwed in, avoiding the bolt rod 100 from deflection, which is beneficial for fastening.
[0026] The bottom wall of the push ring 104 is rotatably connected to a rotating ring 108, which facilitates the movement of the push rod 105. The rotating ring 108 is located on the upper side of the push rod 105.
[0027] In this embodiment: the push ring 104 facilitates the movement of the rotating ring 108, and the rotating ring 108 facilitates the pushing of the push rod 105. This avoids damage caused by friction between the push ring 104 and the push rod 105 during rotational pushing, and is beneficial for pushing and limiting.
[0028] The top wall of the bolt head 101 has a hexagonal insertion groove.
[0029] In this embodiment, the insertion slot facilitates the insertion of a hexagonal handle for turning, and allows for turning with multiple sets of tools, thereby improving the practicality of the device.
