Description

Technical Field

[0001] This utility model relates to the field of high-strength fastening bolts, specifically to a high-strength, anti-disassembly high-strength fastening bolt. Background Technology

[0002] High-strength bolts, also known as high-tightness bolts, are fasteners with high strength and shear resistance. Based on their stress characteristics, high-strength bolts can be divided into two types: ordinary bolts and reamed bolts. High-strength bolts can withstand greater tensile and shear forces and are suitable for applications requiring high load-bearing capacity. In construction engineering, the appropriate high-strength bolts can be selected according to specific application scenarios and requirements, including material, strength grade, and size. At the same time, installation guidelines and specifications must be followed to ensure a tight fit between the bolt and nut and the correct application of preload.

[0003] A search revealed a high-tightness bolt with publication number CN216842601U, specifically disclosing a high-tightness bolt comprising a body, a screw, and sliders. The body has a placement groove at its top, with limiting blocks on both sides of the groove. The body also has an internal sliding groove with a pressure block slidably connected inside. The screw is rotatably connected to a shaft hole at the top of the body and threadedly connected to a screw hole at the top of the pressure block. Two sliders are located inside the sliding grooves, with fastening blocks on their outer surfaces. The bolt also includes a nut and retaining grooves. The nut is threadedly connected to the outer surface of the body, and two retaining grooves are located at opposite ends of the outer surface of the body. When the body is installed in a suitable position, the nut's threaded connection secures it. Rotating the screw causes the pressure block to slide downwards within the sliding groove, thereby pressing the two sliders outwards. This high-tightness bolt offers strong fixation, wide applicability, and a long service life.

[0004] In the use of existing high-strength bolts, due to the varying importance of their applications, if these bolts lack high-strength anti-disassembly capabilities, it could lead to unauthorized disassembly or damage to equipment or structures. Furthermore, the high-strength bolts in the aforementioned comparative cases also lacked high-strength anti-disassembly capabilities. Thus, with long-term use, the lack of high-strength anti-disassembly design necessitates more frequent inspections and maintenance to ensure their tightness, which increases maintenance and time costs.

[0005] Therefore, it is necessary to invent a high-strength, anti-disassembly, high-tightening bolt to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a high-strength, anti-disassembly, high-tightening bolt. This high-tightening bolt achieves its high-strength anti-disassembly capability through a high-tightening main screw, anti-disassembly head, anti-disassembly groove, hexagonal block, mating interface, anti-disassembly nut, and disassembly sleeve. This design prevents unauthorized personnel from disassembling critical components of equipment or products, thus improving safety. Furthermore, the enhanced tightening and anti-disassembly performance reduces thread wear and damage caused by frequent disassembly and reinstallation, extending the bolt's service life. This addresses the problem in existing high-tightening bolts where, due to varying application importance, the lack of high-strength anti-disassembly capability can lead to unauthorized disassembly or damage to equipment or structures. The aforementioned comparative case also lacks high-strength anti-disassembly capability. Therefore, the lack of this design necessitates more frequent inspection and maintenance to ensure its tightness, increasing maintenance and time costs.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-strength, anti-disassembly, high-tightening bolt, comprising a high-tightening main thread and a body for the high-tightening bolt used to penetrate an object;

[0008] A first torque flat washer is disposed on the outside of the high-tightness main screw to enhance torque. The outside of the first torque flat washer is provided with a mating groove. A mating block is movably connected inside the mating groove. An anti-tamper screw head is fixedly installed on the outside of the mating block. An anti-tamper groove is provided inside the anti-tamper groove. A hexagonal block is fixedly installed inside the anti-tamper groove. A mating interface is provided on the outside of the hexagonal block.

[0009] A side anti-slip plate is set at the other end of the high-tightness main screw to increase friction. An anti-tamper nut is movably connected to the other side of the side anti-slip plate. A disassembly sleeve is provided on the outside of the anti-tamper nut. A forward and reverse groove is opened inside the anti-tamper nut. A damping telescopic spring is fixedly installed inside the forward and reverse groove. An anti-tamper ball is movably connected to the front end of the damping telescopic spring.

[0010] Preferably, the mating groove on the outside of the first torque flat washer engages with the mating block fixedly installed on the outside of the anti-tamper screw head, and the mating groove and the mating block are used in conjunction.

[0011] Preferably, the outer surface of the first torque flat washer is provided with a first anti-slip texture, and an elastic washer is movably connected to the right side of the first torque flat washer.

[0012] Preferably, a second torque flat washer is movably connected to the right side of the elastic washer, and the outer side of the second torque flat washer is provided with a second anti-slip texture.

[0013] Preferably, the number of the second anti-slip patterns is set to multiple, and the multiple second anti-slip patterns are distributed in a ring array on the second torque flat pad.

[0014] Preferably, the anti-tamper ball is movably connected to the anti-tamper nut, and the damping extension spring is distributed in a ring array on the forward and reverse grooves.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. This utility model includes a high-tightness main screw, an anti-tamper screw head, an anti-tamper groove, a hexagonal block, a mating interface, an anti-tamper nut, and a disassembly screw sleeve. When using this high-tightness bolt, the anti-tamper screw head at the upper end of the high-tightness main screw is not a conventional hexagon. A special tool is required to insert into the anti-tamper groove, the hexagonal block, and the mating interface to make it fit before it can be turned. This requirement for a special tool increases the difficulty of illegal disassembly, helping to prevent theft and vandalism. After the anti-tamper nut is screwed onto the high-tightness main screw, the forward and reverse grooves, the damping telescopic spring, and the anti-tamper ball inside the anti-tamper nut form an effective self-locking mechanism. When the anti-tamper nut rotates forward, the anti-tamper ball rotates accordingly to compress the damping telescopic spring. The anti-tamper nut moves inward on the screw rod to achieve a tight fit. When attempting to rotate the anti-tamper nut in the reverse direction, without a special disassembly sleeve extending from below to press against the anti-tamper ball, the anti-tamper ball will abut against the threads of the high-tightness main screw rod, creating resistance and preventing the anti-tamper nut from being easily twisted out in the reverse direction. This combination gives the high-tightness bolt a high-strength anti-disassembly capability. This design of the high-tightness bolt can prevent unauthorized personnel from disassembling critical components in equipment or products, thereby improving safety. Moreover, because the bolt's tightening and anti-tampering performance is enhanced, it can reduce thread wear and damage caused by frequent disassembly and reinstallation, thereby extending the bolt's service life.

[0017] 2. This utility model is equipped with a first torque flat washer, a first anti-slip texture, an elastic washer, a second torque flat washer, a second anti-slip texture, and a side anti-slip flat plate. When using this high-tightness bolt, after the high-tightness bolt penetrates the object, the second torque flat washer, the second anti-slip texture, and the side anti-slip flat plate are all set on the surface in close contact with the object. This increases the friction between the high-tightness bolt and the object surface. Moreover, the first torque flat washer, the elastic washer, and the second torque flat washer effectively improve the torque that the bolt can withstand during the tightening process. This helps to ensure that the bolt reaches the required preload, thereby improving the fastening effect of the connection. Among them, the elastic washer can absorb part of the stress during the bolt tightening process, reduce the direct contact between the bolt and the object, thereby reducing the risk of wear and loosening. At the same time, it can also provide additional buffering and fastening force when the bolt is subjected to vibration or impact. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-5 The high-strength, detachable, high-fastening bolt shown includes a high-fastening main thread 1 and a body for the high-fastening bolt that penetrates an object;

[0028] The first torque flat washer 2 is set on the outside of the high-tightness main screw 1 to enhance torque. The first torque flat washer 2 has a mating groove 3 on its outside. The mating groove 3 is movably connected to the mating block 4. The mating block 4 is fixedly installed with an anti-tamper screw head 5 on its outside. The anti-tamper screw head 5 has an anti-tamper groove 6 on its inside. The anti-tamper groove 6 is fixedly installed with a hexagonal block 7 on its inside. The hexagonal block 7 has a mating interface 8 on its outside.

[0029] A side anti-slip flat plate 13 is disposed at the other end of the high-tightening main screw 1 to increase friction. An anti-tamper nut 14 is movably connected to the other side of the side anti-slip flat plate 13. An anti-tamper nut 14 has a disassembly sleeve 15 on its exterior. The anti-tamper nut 14 has a forward / reverse groove 16 inside, and a damping telescopic spring 17 is fixedly installed inside the forward / reverse groove 16. An anti-tamper ball bearing 18 is movably connected to the front end of the damping telescopic spring 17. After the high-tightening main screw 1 is tightened, the forward / reverse groove 16 and the damping sleeve 18 inside the anti-tamper nut 14... The telescopic spring 17 and the anti-tamper ball 18 are designed to form an effective self-locking mechanism. When the anti-tamper nut 14 rotates in the forward direction, the anti-tamper ball 18 rotates in the same direction to compress the damping telescopic spring 17 and move inward on the screw with the anti-tamper nut 14 to achieve a fastening. When attempting to rotate the anti-tamper nut 14 in the reverse direction, without the special disassembly sleeve 15 extending from below to press the anti-tamper ball 18, the anti-tamper ball 18 will abut against the thread of the high-tightening main screw 1, forming resistance, so that the anti-tamper nut 14 cannot be easily twisted out in the reverse direction.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the mating groove 3 on the outside of the first torque flat washer 2 engages with the mating block 4 fixedly installed on the outside of the anti-tamper screw head 5. The mating groove 3 and the mating block 4 work together. The first torque flat washer 2, the elastic washer 10, and the second torque flat washer 11 effectively increase the torque that the bolt can withstand during tightening. This helps to ensure that the bolt reaches the required preload, thereby improving the fastening effect of the connection. The outside of the first torque flat washer 2 is provided with a first anti-slip texture 9. The right side of the first torque flat washer 2 is movably connected to... The elastic washer 10 can absorb some stress during the bolt tightening process, reducing the direct contact between the bolt and the object, thereby reducing the risk of wear and loosening. The right side of the elastic washer 10 is movably connected to the second torque flat washer 11. The outer side of the second torque flat washer 11 is provided with the second anti-slip texture 12. After the high-tightness bolt penetrates the object, the surface in close contact with the object is provided with the second torque flat washer 11, the second anti-slip texture 12 and the side anti-slip flat washer 13, which increases the friction between the high-tightness bolt and the surface of the object.

[0031] like Figure 1 , Figure 4 and Figure 5As shown, the number of second anti-slip grooves 12 is set to multiple, and the multiple second anti-slip grooves 12 are distributed in a ring array on the second torque flat washer 11. The overall structure of the second torque flat washer 11 is simple and easy to operate, and it is convenient for maintenance personnel to replace it in time if a fault occurs. The anti-tamper ball 18 is movably connected to the anti-tamper nut 14. The damping telescopic spring 17 is distributed in a ring array on the forward and reverse groove 16. The anti-tamper nut 14 gives the high-tightness bolt a high-strength anti-disassembly capability. This high-tightness bolt design can prevent unauthorized personnel from disassembling key components in equipment or products, thereby improving safety.

[0032] The working principle of this practical application is as follows: First, take out the high-tightness bolt and align it with the object or equipment to be connected. After the high-tightness bolt penetrates the object, a second torque flat washer 11, a second anti-slip texture 12, and a side anti-slip flat washer 13 are placed close to the object's surface. This increases the friction between the high-tightness bolt and the object's surface. Next, the first torque flat washer 2, the elastic washer 10, and the second torque flat washer 11 effectively increase the torque the bolt can withstand during tightening. This helps ensure the bolt reaches the required preload, thereby improving the connection's tightening effect. The elastic washer 10 absorbs some stress during bolt tightening, reducing direct contact between the bolt and the object, thus reducing the risk of wear and loosening. Finally, the tamper-proof screw head 5 at the upper end of the high-tightness main screw 1 is not a conventional hexagonal shape. A special tool is required to insert into the tamper-proof groove 6, the hexagonal block 7, and the mating interface 8 to engage before it can be turned. This requirement for a special tool increases the difficulty of illegal disassembly, helping to prevent theft and vandalism. Therefore, after the tamper nut 14 is tightened onto the high-tightening main screw 1, the internal clockwise and counterclockwise grooves 16, damping telescopic spring 17, and tamper-proof ball bearings 18 of the tamper nut 14 form an effective self-locking mechanism. When the tamper nut 14 rotates clockwise, the tamper-proof ball bearings 18 rotate in the same direction, compressing the damping telescopic spring 17 and moving inwards on the screw with the tamper nut 14 to achieve a tight lock. Then, when attempting to rotate the tamper nut 14 counterclockwise, a special disassembly sleeve 15 extends from below into the tamper nut 14 to press down on the tamper-proof ball bearings 18, thus preventing the tamper-proof ball bearings from engaging. The bead 18 will abut against the thread of the high-tightness main screw 1, forming resistance, so that the anti-tamper nut 14 cannot be easily twisted out in the reverse direction. This gives the high-tightness bolt a high-strength anti-disassembly capability. This type of high-tightness bolt design can prevent unauthorized personnel from disassembling key components in equipment or products, thereby improving safety. Finally, after completing the installation and use of all the high-tightness bolts according to the above operations, routine maintenance of the bolt is sufficient. In this way, the use of the high-strength anti-disassembly high-tightness bolt is completed.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
