A collet type hinge hexagonal bolt

Abstract

This invention discloses a ferrule-type hinged hexagonal bolt, belonging to the technical field of bolt parts, comprising: a hexagonal head; and a bolt shank, the bolt shank being fixedly connected to the bottom center of the hexagonal head. This ferrule-type hinged hexagonal bolt, through the use of a positioning mechanism, allows the internal positioning rod to be raised and lowered by pressing the hexagonal lifting plate. After the mating screw is inserted and released, the positioning rod automatically pops out under gravity, inserting into the mating ring groove to complete mechanical locking. This achieves rapid locking or unlocking of the mating screw, greatly improving assembly and maintenance efficiency and reducing operational complexity. Through the use of the positioning mechanism, the positioning rod achieves mechanical pin locking of the mating screw. The thread provides the main connection and preload force, while the pin effectively prevents the mating screw from loosening or falling off the hinged screw groove due to vibration or impact, significantly improving the safety and reliability of the connection point. It is suitable for dynamic load environments with vibration, impact, or high safety requirements.

Description

Technical Field

[0001] This invention belongs to the technical field of bolt parts, specifically a ferrule-type hinged hexagonal bolt. Background Technology

[0002] Bolts, as one of the most basic and widely used mechanical fasteners, directly affect the reliability of equipment and structure connections and assembly efficiency. As modern equipment manufacturing develops towards modularization, lightweighting and high reliability maintainability, fastening connection technology not only needs to withstand static and dynamic loads, but also needs to meet complex working conditions such as rapid disassembly and assembly, adaptive angle adjustment, and resistance to vibration and loosening.

[0003] Compression fitting hex bolts are composite fasteners that integrate angle adjustment and quick installation. They are widely used in mechanical connection scenarios that require allowing a certain degree of sway or compensating for installation alignment errors. These bolts typically achieve the hinge function through ball joints, bushings, or special thread structures, and achieve quick pre-installation through compression fittings or similar components. However, existing technical solutions still have the following obvious shortcomings in balancing convenience and reliability:

[0004] 1. Existing hinge bolts often require additional special tools or multiple steps to achieve angle locking or clamp fixation. For example, some designs use independent set screws to lock the hinge angle. This means that operators must frequently switch tools and operating steps during installation and disassembly, making it impossible to achieve quick integrated assembly and disassembly. In situations where space is limited or frequent maintenance is required, this defect seriously affects work efficiency.

[0005] 2. Currently, most solutions rely mainly on the friction of the threaded pair to achieve final locking, or have a relatively simple anti-loosening design. For hinge points that are subjected to continuous vibration, impact loads, or periodic oscillations, a single threaded connection is prone to creep loosening, resulting in a decrease in preload, loosening of the connection point, or even angular offset failure. There is a lack of a rigid locking mechanism plate that forms a redundant backup with the threaded connection. Summary of the Invention

[0006] The purpose of this invention is to: utilize a control mechanism to control the lifting and lowering of the internal positioning rod by pressing the hexagonal lifting plate; after the docking screw is inserted and released, the positioning rod automatically pops out under gravity and inserts into the docking ring groove to complete mechanical locking, achieving rapid locking or unlocking of the docking screw, greatly improving assembly and maintenance efficiency and reducing operational complexity. Through the use of the positioning mechanism, the positioning rod achieves mechanical pin locking of the docking screw, the thread provides the main connection and preload force, while the pin effectively prevents the docking screw from loosening or falling off the hinge screw groove due to vibration and impact, significantly improving the safety and reliability of the connection point. It is suitable for dynamic load environments with vibration, impact, or high safety requirements. The ingenious design of controlling the connection with magnetic attraction and driving the reset with spring force realizes intelligent linkage of internal components. The magnetic attraction force of the first and second magnetic attraction blocks is less than the elastic force of the top spring, ensuring that the positioning rod can reliably extend and lock in the natural state, eliminating complex mechanical transmission or thread adjustment components, making the overall structure more compact and the failure rate lower.

[0007] The technical solution adopted in this invention is as follows: a ferrule-type hinged hexagonal bolt, comprising:

[0008] Hexagonal head;

[0009] A bolt rod, which is fixedly connected to the center of the bottom of the hexagonal head;

[0010] A hinged screw groove is formed on the bolt shank;

[0011] A positioning mechanism is provided inside the bolt rod. The positioning mechanism includes a guide component, a limiting component, and a positioning rod. The limiting component is provided inside the bolt rod, the guide component is provided inside the bolt rod, and the positioning rod is provided inside the guide component.

[0012] A positioning mechanism is located inside a hexagonal head and is connected to a positioning rod. The positioning mechanism includes a pressing component, an adsorption component, and a top spring. The pressing component is located inside the hexagonal head, the adsorption component is located on the pressing component and is connected to the positioning rod, and the top spring is located inside the hexagonal head and is connected to the pressing component.

[0013] The guide component is a guide groove, which is located at the top of the bolt rod, and the positioning rod is movably connected within the guide groove.

[0014] The limiting component includes a limiting cavity and a limiting block. The limiting cavity is opened inside the bolt rod, and the limiting block is fixedly connected to the positioning rod and movably connected inside the limiting cavity.

[0015] The pressing component includes a hexagonal lifting plate and a hexagonal telescopic groove. The hexagonal telescopic groove is formed inside the hexagonal head, and the hexagonal lifting plate is movably connected to the hexagonal telescopic groove.

[0016] The adsorption component includes a first adsorption magnetic block and a second adsorption magnetic block. The first adsorption magnetic block is fixedly connected to the bottom of the hexagonal lifting plate, and the second adsorption magnetic block is fixedly connected to the top of the positioning rod, with the second adsorption magnetic block located directly below the first adsorption magnetic block.

[0017] It also includes a ferrule mechanism, which is mounted on the bolt rod, and the ferrule mechanism includes:

[0018] The ferrule component is located on the bolt rod;

[0019] A hinge component is provided on the ferrule component, and the hinge component is connected to the hinge screw groove;

[0020] The docking component is located on the hinge component and is connected to the positioning rod.

[0021] The ferrule component includes a ferrule block and a mounting block. The ferrule block is movably fitted onto the bolt rod, and the mounting block is fixedly connected to the ferrule block, with the mounting block communicating with the ferrule block.

[0022] The hinge component includes a mounting rod and a connecting screw. The mounting rod is installed inside the mounting block, and the connecting screw is fixedly connected to one end of the mounting rod and threadedly connected to the hinge screw groove.

[0024] The bottom of the bolt rod is provided with a threaded groove.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0026] (1) In this invention, by using the control mechanism, pressing the hexagonal lifting plate can control the lifting of the internal positioning rod. After the docking screw is installed and released, the positioning rod will automatically pop out under the action of gravity and insert into the docking ring groove to complete the mechanical locking, thereby realizing the quick locking or unlocking of the docking screw, which greatly improves the assembly and maintenance efficiency and reduces the complexity of operation.

[0027] (2) In this invention, the positioning mechanism is used to achieve mechanical pin locking of the docking screw by the positioning rod. The thread provides the main connection and preload force, while the pin effectively prevents the docking screw and the hinge screw groove from loosening or falling off due to vibration and impact, which significantly improves the safety and reliability of the connection point. It is suitable for dynamic load environments with vibration, impact or high safety requirements.

[0028] (3) In this invention, the ingenious design of magnetic attraction control connection and spring force drive reset realizes the intelligent linkage of internal components. The magnetic attraction of the first magnetic block and the second magnetic block is less than the elastic force of the top spring, ensuring that the positioning rod can reliably extend and lock in the natural state, eliminating the need for complex mechanical transmission or threaded adjustment components, making the overall structure more compact and the failure rate lower.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0039] Example 1, refer to Figure 1-8 A type of compression fitting hexagonal bolt, comprising:

[0040] Hexagonal head 1;

[0041] Bolt rod 2 is fixedly connected to the center of the bottom of hexagonal head 1;

[0042] Hinged screw groove 4 is formed on bolt rod 2;

[0043] The positioning mechanism is located inside the bolt rod 2. The positioning mechanism includes a guide component, a limiting component, and a positioning rod 9. The limiting component is located inside the bolt rod 2, the guide component is located inside the bolt rod 2, and the positioning rod 9 is located inside the guide component.

[0044] The positioning mechanism is located inside the hexagonal head 1 and is connected to the positioning rod 9. The positioning mechanism includes a pressing component, an adsorption component, and a top spring 10. The pressing component is located inside the hexagonal head 1, the adsorption component is located on the pressing component and is connected to the positioning rod 9, and the top spring 10 is located inside the hexagonal head 1 and is connected to the pressing component.

[0045] In this implementation scheme: the hexagonal head 1 and the bolt rod 2 are fixedly connected to form an integral bolt structure. The hinged screw groove 4 connects the bolt as a whole to the outside, ensuring the overall performance. The positioning rod 9 moves up and down within the bolt rod 2 to complete the positioning and use. The top spring 10 controls the position of the pressing component through its elasticity, enabling the hexagonal head 1 to be used as an internal hexagon. Furthermore, the top spring 10 controls the use of the adsorption component, causing the positioning rod 9 to move up and down to complete the overall use.

[0046] Specifically: the guide component is the guide groove 6, which is opened at the top of the bolt rod 2, and the positioning rod 9 is movably connected in the guide groove 6.

[0047] In this embodiment, the guide groove 6 restricts the movement of the positioning rod 9 during use, ensuring the overall performance.

[0048] Specifically: The limiting component includes a limiting cavity 5 and a limiting block 8. The limiting cavity 5 is opened inside the bolt rod 2, and the limiting block 8 is fixedly connected to the positioning rod 9, and the limiting block 8 is movably connected inside the limiting cavity 5.

[0049] In this embodiment, the limiting cavity 5 and the limiting block 8 are used in a corresponding manner to restrict the position of the entire structure during the movement of the positioning rod 9, thereby preventing the positioning rod 9 from moving out.

[0050] Specifically: The pressing component includes a hexagonal lifting plate 11 and a hexagonal telescopic groove 7. The hexagonal telescopic groove 7 is opened inside the hexagonal head 1, and the hexagonal lifting plate 11 is movably connected inside the hexagonal telescopic groove 7.

[0051] In this embodiment: the hexagonal lifting plate 11 can be raised and lowered in the hexagonal telescopic groove 7 to complete the overall use. The bottom of the top spring 10 is fixed to the bottom of the hexagonal telescopic groove 7, and the top of the top spring 10 is fixed to the hexagonal lifting plate 11. The position of the hexagonal lifting plate 11 is limited by the elastic force of the top spring 10.

[0052] Specifically, the adsorption component includes a first adsorption magnetic block 12 and a second adsorption magnetic block 13. The first adsorption magnetic block 12 is fixedly connected to the bottom of the hexagonal lifting plate 11, and the second adsorption magnetic block 13 is fixedly connected to the top of the positioning rod 9, with the second adsorption magnetic block 13 located directly below the first adsorption magnetic block 12.

[0053] In this embodiment, the first magnetic adsorption block 12 and the second magnetic adsorption block 13 cooperate with each other to allow the hexagonal lifting plate 11 to be adsorbed onto the positioning rod 9 for use. Furthermore, the magnetic attraction between the first magnetic adsorption block 12 and the second magnetic adsorption block 13 is smaller than the elastic force of the top spring 10.

[0054] Specifically: it also includes a ferrule mechanism, which is mounted on bolt rod 2. The ferrule mechanism includes:

[0055] The ferrule component is located on the bolt rod 2;

[0056] A hinge component is provided on the sleeve component, and the hinge component is connected to the hinge screw groove 4;

[0057] The docking component is located on the hinge component and is connected to the positioning rod 9.

[0058] In this embodiment, the ferrule component, the hinge component, and the docking component cooperate with each other to enable the ferrule mechanism to dock with the bolt rod 2.

[0059] Specifically: The ferrule component includes a ferrule block 14 and a mounting block 15. The ferrule block 14 is movably sleeved on the bolt rod 2, and the mounting block 15 is fixedly connected to the ferrule block 14, and the mounting block 15 is in communication with the ferrule block 14.

[0060] In this embodiment, the sleeve block 14 and the mounting block 15 are existing technologies and will not be described in detail here.

[0061] Specifically: The hinge component includes a mounting rod 18 and a connecting screw 17. The mounting rod 18 is installed inside the mounting block 15, and the connecting screw 17 is fixedly connected to one end of the mounting rod 18, and the connecting screw 17 is threadedly connected to the hinge screw groove 4.

[0062] In this embodiment, the mounting rod 18 and the docking screw 17 cooperate with each other and correspond to the hinge screw groove 4 to complete the overall use.

[0063] Specifically: the docking component is a docking ring groove 16, which is formed on the docking screw 17 and is connected to the positioning rod 9.

[0064] In this embodiment, the position of the mating ring groove 16 corresponds to the position of the positioning rod 9, and the connection between the mating screw 17 and the hinged screw groove 4 is not just a connection between threads, which improves the overall stability.

[0065] Specifically: The bottom of the bolt rod 2 is provided with a threaded groove 3.

[0066] In this embodiment: the threaded groove 3 ensures the overall use of the bolt.

[0067] In use, press the hexagonal lifting plate 11 to compress the top spring 10, causing the first magnetic adsorption block 12 to align with the second magnetic adsorption block 13, thus aligning the positioning rod 9. The positioning rod 9 then enters the guide groove 6. After placing the sleeve block 14 on the bolt rod 2, install the mounting rod 18, allowing the connecting screw 17 to enter the hinge screw groove 4. After completion, release the hexagonal lifting plate 11. Under the elastic force of the top spring 10, the hexagonal lifting plate 11 is lifted to the top of the hexagonal telescopic groove 7. At this time, the first magnetic adsorption block 12 fixed at the bottom of the hexagonal lifting plate 11 and the second magnetic adsorption block 13 align. The second magnetic adsorption block 13 fixed to the top of the positioning rod 9 separates. At the same time, through the cooperation of the limiting cavity 5 and the limiting block 8, due to the disappearance of the magnetic force, the positioning rod 9 extends out of the guide groove 6 under its own gravity and docks with the docking ring groove 16, completing the positioning of the docking screw 17 in the hinge screw groove 4. When disassembling the whole, the hexagonal head 1 can be rotated by controlling the wrench. When disassembling in parts, press the hexagonal lifting plate 11, and with the cooperation of the first magnetic adsorption block 12 and the second magnetic adsorption block 13, the positioning rod 9 is disengaged from the docking ring groove 16, and the whole disassembly is completed.

[0068] The control method of this invention is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this invention is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
