Description

Technical Field

[0001] This utility model relates to the field of fastener technology, specifically to an improved high-strength fastener. Background Technology

[0002] Fasteners come in a wide variety of types and can broadly refer to all mechanical parts used for fastening connections. They are commonly found in the fields of machinery manufacturing, bridge construction, and the processing of vehicles, ships, and aircraft. They often appear in sets of bolts and nuts, and come in different sizes to install different components.

[0003] A search revealed Chinese patent CN223282363U, which discloses a high-strength, lightweight fastener with an improved structure, comprising a screw block and a bolt rod. The bolt rod is welded to the bottom center of the screw block, and a hexagonal chamber is provided inside the top of the screw block. Push blocks are provided behind and on both sides of the hexagonal chamber, and thin rods are fixed to both sides of each push block. The outer surface of the screw block is provided with three sets of slots. This high-strength, lightweight fastener with an improved structure features a hexagonal chamber inside the top of the screw block. Depending on the end specifications of the tool to be inserted, the screw is rotated in three slots to screw into and out of the screw hole. Thin rods embedded in slots on both sides act as restraints. The push block connected to the horizontally rotated screw slides, then tightly fits around the tool body, which is smaller than the hexagonal chamber, for locking and fixing. This solves the problem of fixing the insertion slot specifications. However, this patent involves inserting the tool into the hexagonal chamber and rotating it to install and remove the fastener. When the inner wall of the hexagonal chamber wears down, the tool cannot rotate the fastener, making installation and removal difficult and resulting in poor performance.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to provide an improved high-strength fastener, which solves the problem in the prior art where the patent involves inserting a tool into a hexagonal cavity and then rotating the tool to disassemble and assemble the fastener. However, when the inner wall of the hexagonal cavity is worn, the tool cannot drive the fastener to rotate, which is not conducive to the disassembly and assembly of the fastener and results in poor performance.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] An improved high-strength fastener includes a hexagonal nut, the upper surface of which extends into a hexagonal cavity, and a slotted groove at the bottom of the cavity; and a transmission assembly disposed outside the hexagonal nut, the transmission assembly including a mounting screw hole on the outer wall of the hexagonal nut, a threaded post threaded onto the inner wall of the mounting screw hole, a connecting block fixedly connected to the end of the threaded post away from the hexagonal nut, and a fixing rod fixedly connected to the end of the connecting block away from the threaded post, the fixing rod having a through hole on its surface.

[0008] Preferably, the bottom of the hexagonal nut is fixedly connected to a connecting circular plate, and the connecting circular plate has an oil guiding cavity inside.

[0009] Preferably, the bottom of the oil guiding cavity is provided with a plurality of oil guiding holes in a ring array, and the number of oil guiding holes is not less than sixteen.

[0010] Preferably, a connected oil filling groove is provided on one side of the oil guiding cavity, and a limit plug is movably installed inside the oil filling groove.

[0011] Preferably, a screw is fixedly connected to the bottom of the connecting circular plate, and a reinforcing washer is movably sleeved on the outer wall of the screw.

[0012] Preferably, the bottom of the reinforcing washer is provided with a fastening nut, and the fastening nut is threaded onto the outer wall of the screw.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0014] 1. Through the structural design of hexagonal nut, hexagonal chamber, connecting block, slotted groove, fixing rod, mounting screw hole, threaded post and through hole, this fastener can be disassembled and assembled in multiple ways, thereby meeting the disassembly and assembly needs of different scenarios and achieving good performance.

[0015] 2. Through the structural design of connecting round plate, oil groove, limit plug, oil guide hole and oil guide cavity, the threaded part of the screw can be easily lubricated, thereby improving the efficiency of disassembly and assembly. At the same time, the groove opening of the oil groove can be sealed by the limit plug, thereby preventing external dust from entering the oil guide cavity when lubrication is not needed, thus improving the convenience of the fastener.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 An improved high-strength fastener includes a hexagonal nut 1, the upper surface of the hexagonal nut 1 extending into the interior to form a hexagonal cavity 4, and a slotted groove 8 formed at the bottom of the interior of the hexagonal cavity 4;

[0024] The transmission assembly is located on the outside of the hexagonal nut 1. The transmission assembly includes a mounting screw hole 12 on the outer wall of the hexagonal nut 1. A threaded post 13 is threadedly installed on the inner wall of the mounting screw hole 12. A connecting block 7 is fixedly connected to the end of the threaded post 13 away from the hexagonal nut 1. A fixing rod 9 is fixedly connected to the end of the connecting block 7 away from the threaded post 13. A through hole 14 is opened through the surface of the fixing rod 9.

[0025] A screw rod 5 is fixedly connected to the bottom of the connecting circular plate 2. A reinforcing washer 3 is movably sleeved on the outer wall of the screw rod 5. A fastening nut 6 is provided at the bottom of the reinforcing washer 3, and the fastening nut 6 is threaded onto the outer wall of the screw rod 5.

[0026] Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, during use, a tool can be inserted into the hexagonal chamber 4 to facilitate rotation of the fastener. The fastener can also be rotated by turning the hexagonal nut 1 with a wrench, or by inserting a flathead screwdriver into the slot 8. Furthermore, when no tools are available, a stick can be inserted into the through hole 14 to assemble and disassemble the fastener. The cooperation between the mounting screw hole 12 and the threaded post 13 facilitates the assembly and disassembly of the fixing rod 9. This better meets the needs of different scenarios and solves the problem of the previous patent where inserting a tool into the hexagonal chamber 4 and then rotating it to assemble and disassemble the fastener resulted in wear on the inner wall of the hexagonal chamber 4, preventing the tool from rotating the fastener and hindering its assembly and disassembly, leading to poor performance.

[0027] The bottom of the hexagonal nut 1 is fixedly connected to a connecting circular plate 2. The connecting circular plate 2 has an oil guiding cavity 16 inside. The bottom of the oil guiding cavity 16 has multiple oil guiding holes 15 arranged in a ring array. The number of oil guiding holes 15 is not less than sixteen. A connected oil filling groove 10 is provided on one side of the oil guiding cavity 16. A limit plug 11 is movably installed inside the oil filling groove 10.

[0028] Specifically, such as Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, when the fastener is difficult to disassemble, lubricating oil can be added to the oil guide cavity 16 through the oil filling groove 10 and finally discharged through multiple oil guide holes 15, thereby lubricating the threaded part of the screw 5 and facilitating disassembly. At the same time, the groove opening of the oil filling groove 10 can be sealed by the limiting plug 11 to prevent external dust from entering the oil guide cavity 16 when lubricating oil is not needed, thereby improving the convenience of the fastener.

[0029] Working principle: In this application, a tool can be inserted into the hexagonal chamber 4 to facilitate the rotation of the fastener. The hexagonal nut 1 can also be rotated with a wrench, and a flathead screwdriver can be inserted into the slot 8 to achieve the same rotation. Furthermore, when no tools are available, a stick can be inserted into the through hole 14 to facilitate the fastener's assembly and disassembly. The mounting screw hole 12 and the threaded post 13 facilitate the assembly and disassembly of the fixing rod 9, thus better meeting the needs of different scenarios. Secondly, when the fastener is difficult to disassemble, lubricating oil can be added to the oil guide cavity 16 through the oil filling groove 10 and finally discharged through multiple oil guide holes 15 to lubricate the threaded portion of the screw 5, thereby facilitating disassembly.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
