Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically a quick-release nut. Background Technology

[0002] Bolt assemblies are common fasteners, with a screw threaded through the connector and secured by a nut. Existing nuts are typically ordinary hexagonal nuts with threads, which take a long time to rotate into place during installation, thus impacting installation progress. In current technology, to improve assembly efficiency and reduce nut rotation time, the conventional approach is to adjust the screw length according to the thickness of the target connector. However, this method only reduces the number of rotations by changing the length of the screw's tail end, thus shortening installation time to some extent. However, this method has limitations. Specifically, it only improves assembly efficiency by shortening the screw length and does not address the nut's structural design itself. It still cannot fundamentally solve the inherent structural defects of traditional nuts, requiring multiple turns during installation, resulting in low installation efficiency.

[0003] Based on the above problems, this utility model proposes a quick-install nut. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a quick-install nut that can fundamentally solve the inherent structural defects of traditional nuts, and greatly improves the installation efficiency by eliminating the need to turn it many times during use.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A quick-release nut includes a nut body, which comprises a cylindrical body, a female core, and an end cap. The female core includes a chip and a guide rod, with the chip and the screw having a threaded structure. The chip and the guide rod are movably connected, and the upper end of the guide rod is connected to the end cap. A groove adapted to the guide rod is provided on the upper end face of the cylindrical body. Through holes are provided at the center of the end cap and the center of the bottom of the cylindrical body, respectively, corresponding to the screw.

[0007] Compared with the prior art, the beneficial effects of this utility model are:

[0008] This invention adds a movable female core structure inside the cylinder, allowing the end cap and cylinder to press the female core together during assembly, making it contact the screw. Then, by turning the cylinder 0.5 to 1.5 turns, assembly can be completed quickly. This fundamentally solves the structural defect of traditional nuts, which require turning them dozens of times. Furthermore, this device can be quickly disassembled by simply pulling the cylinder, making it highly efficient.

[0024] The present invention will be further described below with reference to specific embodiments. The purpose of this description is only to better understand the content of the present invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0025] A quick-install nut, the nut body is composed of a cylinder 1, a female core 2 and an end cap 3. The female core 2 is composed of a chip 201 and a guide rod 202. The end cap 3 is a circular structure. The center of the end cap 3 and the bottom of the cylinder 1 are respectively provided with through holes adapted to the screw 17, so that the screw 17 can pass through the end cap 3 and the cylinder 1.

[0026] Two guide rods 202 are arranged opposite each other, and the upper end of each guide rod 202 is fixedly connected to the lower surface of the end cover 3.

[0027] Each guide rod 202 has a hollow interior, and each guide rod 202 has a mounting groove 4 connected to the hollow structure on its side surface. One end of the chip 201 is movably connected to the mounting groove 4. Specifically, one end of the chip 201 is fixedly connected to a rotating shaft 5 along its height direction, and both ends of the rotating shaft 5 extend beyond the upper and lower end faces of the chip 201. A movable notch 6 is provided on one side of the mounting groove 4 corresponding to the height of the chip 201. The chip 201 is inserted upward from the lower end of the guide rod 202 along the mounting groove 4. After the chip 201 is completely placed in the movable notch 6, the chip 201 can be rotated by the rotating shaft 5 to place the chip 201 in the movable notch 6. During assembly, the movable notch 6 can limit the chip 201 and prevent the chip 201 from falling off the guide rod 202.

[0028] The chip 201 has an overall arc-shaped structure. The inner wall of the chip 201 is a vertical surface. The inner wall surface of the chip 201 is provided with a thread structure 2011 that is adapted to the screw 17. The outer wall of the chip 201 is a slope structure 2012 that is inclined from bottom to top. The inner wall of the cylinder 1 is provided with slopes 7 that are adapted to the slope structure 2012 at the installation positions of the two chips 201. The surface of the slope 7 is an arc surface that is adapted to the curvature of the chip 201.

[0029] Two guide posts 8 are also vertically fixed on the lower surface of the end cap 3. The guide posts 8 and the guide rod 202 are arranged at intervals around the center of the end cap 3.

[0030] The lower end of the guide rod 202 is provided with a locking block 9, and the lower end of the guide post 8 is provided with a locking block 10. The locking blocks 9 and 10 are arranged opposite to each other. The upper end of the cylinder 1 is provided with a matching slot 11 corresponding to the lower end of the guide rod 202, and the upper end of the cylinder 1 is provided with a matching slot 12 corresponding to the lower end of the guide post 8. The guide rod 202 and the guide post 8 slide up and down inside the cylinder 1 along their respective slots.

[0031] The opposing surfaces of the first card block 9 and the second card block 10 are respectively provided with inclined surface structure 2 13. The upper end surface of the cylinder 1 is provided with a limiting protrusion 14, which is placed between the first card block 9 and the second card block 10. The two sides of the limiting protrusion 14 are respectively provided with inclined surface structure 3 15 adapted to the inclined surface structure 2 13.

[0032] In this embodiment, in order to facilitate the operator's gripping of the cylinder 1, grooves 16 are symmetrically provided on the outer surface of the cylinder 1 to facilitate the operator's thumb gripping and rotation.

[0033] When using this device, the chip 201 and guide rod 202 are assembled first, and then the female core 2 and end cap 3 are inserted into the cylinder 1 as a whole. When the female core 2 is inserted into the cylinder 1, the inclined structure 2 13 on the guide rod 202 and guide post 8 cooperates with the inclined structure 3 15 on the cylinder 1, so that the guide rod 202 and guide post 8 are inserted into their respective slots. At the same time, due to the limiting protrusion 14 limiting the locking block 1 9 and locking block 2 10, the female core 2 will not detach from the cylinder 1. When the guide rod 202 and guide post 8 are inserted into the cylinder 1, the chip 201 also enters the interior of the cylinder 1.

[0034] When the bolt is inserted through the items on the upper and lower sides, the cylinder 1 and the end cap 3 are initially separated. One end of the nut end cap 3 is fitted onto the end of the screw 17. Since the chip 201 inside the cylinder 1 is a movable structure, the nut can quickly reach the ground of the item below. Then the cylinder 1 is pulled back. As the cylinder 1 moves upward, the ramp 7 presses the inclined structure 2012 of the chip 201. The upper end face of the cylinder 1 contacts the lower end face of the end cap 3. At this time, the two chips 201 are pressed and tightly cooperate with the screw 17. Then the cylinder is rotated 0.5-1.5 turns to complete the locking of the bolt.

[0035] When removing the nut, pull down the nut so that the ramp 7 contacts the inclined structure 2012 of the chip 201, causing the chip 201 and the screw 17 to loosen and no longer be threaded together. Continue to pull down the cylinder 1 to remove the nut body.

[0036] This invention utilizes the combination of the chip's inclined surface structure and the cylinder's sloping structure to achieve quick installation and removal of the nut, fundamentally solving the structural defect of traditional nuts that require multiple turns, and greatly improving installation efficiency.

[0037] The above description is merely a preferred embodiment of the present utility model and does not limit the scope of the present utility model. All equivalent changes made based on the content of the present utility model specification and its drawings are included within the scope of the present utility model.
