Description

Technical Field

[0001] This utility model relates to the field of fastener technology, and in particular to a high-sealing, high-strength nut fastener. Background Technology

[0002] Existing high-sealing, high-strength nuts and fasteners have several shortcomings in use: In traditional structures, bolt installation and subsequent tightening operations often need to be performed in separate steps, requiring additional tools or manual switching of operating modes, making the process cumbersome and inefficient. Furthermore, existing fasteners struggle to automatically switch between installation and further tightening. After bolt tightening, if secondary tightening is needed to enhance sealing and strength, power transmission is not smooth enough, easily leading to incomplete tightening and compromising overall sealing and strength. In addition, some fasteners have poorly designed power transmission structures, prone to jamming during rotation, affecting ease of operation and failing to meet the actual demands for high sealing, high strength, and efficient operation. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a high-sealing, high-strength nut fastener. A rotating post is rotatably mounted on the upper surface of the bolt head. A spring inside the rotating post can eject a sliding rod, causing the sliding rod to insert into a groove inside the bolt head, pushing out a T-shaped post. When a worker uses a screwdriver with a Phillips head to control the rotation of the rotating post, the sliding rod inside the rotating post transmits rotational power to the bolt head, causing the entire component to rotate and tighten. When the T-shaped post inside the bolt head abuts against the surface of the fastened object, it pushes the T-shaped post and sliding rod upward against the spring force until the sliding rod completely returns to the rotating post. At this point, the rotation of the rotating post no longer causes the bolt head to rotate. The rotating post can then only rotate the screw. The rotation of the screw causes the slider to descend, pressing against the crossbar and causing it to protrude from inside the bolt, thus laterally compressing the fastened object, increasing the tightening effect, preventing loosening of the bolt fastening part, and ensuring a tight seal. No additional operation is required to switch between bolt installation and further tightening operations.

[0004] This utility model also provides a high-sealing, high-strength nut fastener, comprising: a rotating column, the rotating column having a cross groove inside, a spring fixedly connected to the inner side wall of the rotating column, a sliding rod fixedly connected to the lower surface of the spring, a bolt head rotatably connected to the lower surface of the rotating column, a sliding groove inside the bolt head, and a T-shaped column slidably connected to the inner side wall of the sliding groove; and a screw rod, a bolt shank rotatably connected to the side surface of the screw rod, a slider slidably connected to the inner side wall of the bolt shank, and a crossbar slidably connected to the inner side wall of the bolt shank. The above components include a rotating post rotatably mounted on the upper surface of the bolt head. A spring inside the rotating post ejects a sliding rod, which inserts into a groove within the bolt head, pushing out a T-shaped post. When a screwdriver is used with a Phillips head to control the rotation of the rotating post, the sliding rod inside the rotating post transmits rotational power to the bolt head, causing the entire component to rotate and tighten. When the T-shaped post inside the bolt head presses against the surface of the object being tightened, it pushes the T-shaped post and sliding rod upwards against the spring force until the sliding rod completely returns to the rotating post. At this point, the rotation of the rotating post no longer causes the bolt head to rotate. The rotating post then only rotates the screw, causing the slider to descend and press against the crossbar, protruding it from inside the bolt. This provides lateral compression to the object being tightened, increasing the tightening effect, preventing loosening of the bolt, and ensuring a tight seal. No additional operation is required to switch between bolt installation and further tightening.

[0005] According to the present invention, a high-sealing, high-strength nut fastener comprises a rotating post and a bolt head end face that are hexagonal, and a sliding rod side surface that is slidably connected to the inner wall of the rotating post. These components allow the fastener to be tightened in other ways, enabling the sliding rod to slide stably inside the rotating post.

[0006] According to the high-sealing, high-strength nut fastener of this utility model, the bottom end of the sliding rod is located inside the sliding groove, and the lower surface of the sliding rod is in contact with the upper surface of the T-shaped post. These components enable the sliding rod to push out the T-shaped post and drive the bolt head to rotate.

[0007] According to the present invention, a high-sealing, high-strength nut fastener comprises several sliding rods and springs arranged in an array inside the rotating column, and several sliding grooves and T-shaped posts arranged in an array inside the bolt head. These components increase the stability of the bolt head rotation driven by the sliding rod.

[0008] According to the present invention, a high-sealing, high-strength nut fastener has a T-shaped post with its bottom end located below the bolt head. The length of the sliding rod inside the groove is the same as the length of the T-shaped post below the bolt head. These components allow the bolt head to push the T-shaped post back into the groove as it approaches the object being fastened, and also drive the sliding rod back into the rotating post. Furthermore, when the rotating post drives the sliding rod to rotate, the sliding rod no longer drives the bolt head to rotate.

[0009] According to the present invention, a high-sealing, high-strength nut fastener is provided, wherein the upper surface of the screw is fixedly connected to the lower surface of the rotating post, and the top end of the screw is rotatably connected to the inner wall of the bolt head. These components enable the rotating post to drive the screw to rotate stably.

[0010] According to the present invention, a high-sealing, high-strength nut fastener comprises a bolt shank with its upper surface fixedly connected to the lower surface of its head, and a slider disposed on the side surface of the bolt shank. These components enable the bolt head to drive the bolt shank to rotate, and the slider's movement is achieved by the rotation of the bolt shank.

[0011] According to the present invention, a high-sealing, high-strength nut fastener has a slider whose lower surface contacts the upper surface of a crossbar, and two crossbars are located on either side of the slider. These components allow the slider to descend and push the crossbars out of the bolt shank.

[0012] Beneficial effects:

[0013] Compared with the prior art, this utility model has a rotating column rotatably mounted on the upper surface of the bolt head. A spring inside the rotating column can eject a sliding rod, allowing the sliding rod to insert into a groove inside the bolt head, pushing out a T-shaped post. When the operator uses a screwdriver with a Phillips head to control the rotation of the rotating column, the sliding rod inside the rotating column transmits rotational power to the bolt head, causing the entire component to rotate and tighten. When the T-shaped post inside the bolt head abuts against the surface of the fastened item, it pushes the T-shaped post and sliding rod upward against the spring force until the sliding rod completely returns to the rotating column. At this point, the rotation of the rotating column no longer drives the bolt head to rotate. The rotating column then only drives the screw to rotate. The rotation of the screw causes the slider to descend, pressing against the crossbar and causing it to protrude from inside the bolt shank, thus laterally compressing the fastened item, increasing the tightening effect, preventing loosening of the fastener, and ensuring a tight seal. No additional operation is required to switch between bolt installation and further tightening operations. Attached Figure Description

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4 This utility model provides a high-sealing, high-strength nut fastener, comprising: a rotating column 1, a cross groove 2 inside the rotating column 1, a spring 3 fixedly connected to the inner wall of the rotating column 1, a sliding rod 4 fixedly connected to the lower surface of the spring 3, the side surface of the sliding rod 4 slidably connected to the inner wall of the rotating column 1, several sliding rods 4 and springs 3 arranged in an array inside the rotating column 1, a bolt head 5 rotatably connected to the lower surface of the rotating column 1, the end faces of the rotating column 1 and the bolt head 5 being hexagonal, a groove 6 inside the bolt head 5, the bottom end of the sliding rod 4 located inside the groove 6, a T-shaped post 7 slidably connected to the inner wall of the groove 6, the lower surface of the sliding rod 4 contacting the upper surface of the T-shaped post 7, several grooves 6 and T-shaped posts 7 arranged in an array inside the bolt head 5, the bottom end of the T-shaped post 7 located below the bolt head 5, and the length of the sliding rod 4 inside the groove 6 being the same as the length of the T-shaped post 7 below the bolt head 5.

[0023] Specifically, a rotating post 1 is rotatably mounted on the upper surface of the bolt head 5. A spring 3 inside the rotating post 1 can eject the sliding rod 4, causing the sliding rod 4 to insert into the sliding groove 6 inside the bolt head 5, pushing out the T-shaped post 7. When the operator uses a screwdriver with a cross groove 2 to control the rotation of the rotating post 1, the sliding rod 4 inside the rotating post 1 will transmit the rotational power to the bolt head 5, causing the entire component to rotate and tighten. When the T-shaped post 7 inside the bolt head 5 abuts against the surface of the fastened item, it will push the T-shaped post 7 and the sliding rod 4 to rise against the elastic force of the spring 3 until the sliding rod 4 completely returns to the inside of the rotating post 1. After that, the rotation of the rotating post 1 will no longer cause the bolt head 5 to rotate, realizing the switching between the installation and further tightening of the fastener.

[0024] The screw 8 has its upper surface fixedly connected to the lower surface of the rotating column 1. The top end of the screw 8 is rotatably connected to the inner wall of the bolt head 5. A bolt shank 9 is rotatably connected to the side surface of the screw 8. The upper surface of the bolt shank 9 is fixedly connected to the lower surface of the bolt head 5. A slider 10 is slidably connected to the inner wall of the bolt shank 9. The slider 10 is located on the side surface of the screw 8. A crossbar 11 is slidably connected to the inner wall of the bolt shank 9. The lower surface of the slider 10 is in contact with the upper surface of the crossbar 11. There are two crossbars 11 located on both sides of the slider 10.

[0025] Specifically, the rotating column 1 can drive the screw 8 to rotate. The rotation of the screw 8 can drive the slider 10 to descend and press against the crossbar 11 so that it protrudes from the bolt shank 9. This causes lateral compression of the fastened item, increasing the fastening effect, preventing the fastening part of the bolt head 5 from loosening, and ensuring the fastening seal. No additional operation is required to complete the switching between fastener installation and further tightening operations.

[0026] Working principle: During the use of the fastener, a rotating post 1 is rotatably mounted on the upper surface of the bolt head 5. A spring 3 inside the rotating post 1 can eject a sliding rod 4, causing the sliding rod 4 to insert into the groove 6 inside the bolt head 5, pushing out the T-shaped post 7. When the operator uses a screwdriver with a Phillips head 2 to control the rotation of the rotating post 1, the sliding rod 4 inside the rotating post 1 transmits rotational power to the bolt head 5, causing the entire component to rotate and tighten. When the T-shaped post 7 inside the bolt head 5 presses against the surface of the fastened object, it pushes the T-shaped post 7 and the sliding rod 4 against the spring force of the spring 3. As the slide bar 4 rises until it is completely back inside the rotating column 1, the rotation of the rotating column 1 will no longer cause the bolt head 5 to rotate, thus switching between fastener installation and further tightening. The rotating column 1 can then only drive the screw 8 to rotate. The rotation of the screw 8 can drive the slider 10 to descend, pressing against the crossbar 11 so that it protrudes from inside the bolt shank 9, thus laterally squeezing the fastened item, increasing the tightening effect, preventing the fastening part of the bolt head 5 from loosening, and ensuring the tightness and sealing. No additional operation is required to complete the switching between fastener installation and further tightening.

[0027] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
