Description

Technical Field

[0001] This utility model relates to the field of fastener technology, specifically to stainless steel threaded fasteners that facilitate quick installation. Background Technology

[0002] Threaded fasteners are a type of connecting component widely used in various fields such as machinery and construction. They achieve a tight connection between parts through the engagement of threads. In many fields such as mechanical assembly and building installation, threaded fasteners are indispensable connecting components.

[0003] Traditional threaded fasteners often suffer from problems such as slow installation speed, poor operational stability, and easy loosening during installation. Utility Model Content

[0004] The purpose of this invention is to provide stainless steel threaded fasteners that are easy to install quickly, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a stainless steel threaded fastener that is easy to install quickly, including a screw and a screw head. The screw includes a fully threaded locking section, a spiral groove fast-advance section and a tapered guide head. An anti-loosening ring is sleeved on the surface of the fully threaded locking section. An internal hexagonal drive groove is opened on the top of the screw head. Two arc-shaped guide grooves are symmetrically opened on the side wall of the screw head. A claw mechanism is provided on the outside of the screw.

[0006] Preferably, the anti-loosening ring is made of copper alloy, and the inner surface of the anti-loosening ring is provided with a sawtooth thread that matches the full thread locking section.

[0007] Furthermore, the anti-loosening ring is made of copper alloy, and its inner surface is provided with a sawtooth thread that matches the fully threaded locking section. Through the material properties of copper alloy and the interlocking effect of the sawtooth thread, the anti-loosening effect of the fastener in the locked state is enhanced.

[0008] Preferably, the surface of the spiral groove rapid advance section is provided with four planes, and each of the four planes is provided with a fixing groove.

[0009] Furthermore, the surface of the spiral groove fast-forward section is uniformly provided with four planes, and each of these four planes is provided with a fixing groove for cooperation with the claw mechanism or other external components to achieve the function of quick installation or fixing.

[0010] Preferably, a nut is threaded onto the outer side of the screw.

[0011] Furthermore, a nut is provided on the outside of the screw, and the nut is threaded to the screw. The presence of the nut increases the versatility and flexibility of the fastener, allowing the tightness of the fastener to be adjusted or disassembled as needed.

[0012] Preferably, a magnetic element is provided at the bottom of the internal hexagonal drive groove, and a nylon friction-reducing strip is embedded in the arc-shaped guide groove.

[0013] Furthermore, the bottom of the internal hexagonal drive slot is equipped with a magnetic element for adsorbing tools or assisting in positioning during installation. At the same time, the arc-shaped guide slot is embedded with nylon anti-friction strips to reduce friction between the screw head and surrounding parts during installation or disassembly, thereby improving the smoothness of operation.

[0014] Preferably, the claw mechanism includes a support ring, a spring is fixedly connected to the inner side of the support ring, and a fixing plate is fixedly connected to the end of the spring away from the support ring.

[0015] Furthermore,

[0016] Preferably, the support rings are located on the outer side of the spiral groove fast-forward section and the top of the nut, respectively. There are eight springs and four fixing plates. The eight springs are evenly distributed in pairs on the inner side of the support rings and the outer side of the four fixing plates. The ends of the four fixing plates away from the springs are respectively inserted into the fixing grooves opened on the four planes of the spiral groove fast-forward section.

[0017] Furthermore, the support ring is located outside the spiral groove fast-forward section and at the top of the nut. Eight springs are provided, and two are evenly distributed in groups of two inside the support ring and outside the four fixing plates. The ends of the four fixing plates away from the springs are respectively inserted into the fixing grooves opened on the four planes of the spiral groove fast-forward section, ensuring that the claw mechanism can be firmly fixed on the screw and form an effective cooperation relationship with the spiral groove fast-forward section.

[0018] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0019] First, this utility model inserts a tapered guide head into the mounting hole to guide the screw to the correct position. Using an internal hexagonal wrench that matches the internal hexagonal drive groove, the wrench is inserted into the drive groove. Because the bottom of the drive groove has a magnetic element, it can attract the wrench, preventing it from slipping during installation and improving operational stability. Rotating the wrench drives the screw head and screw to rotate. At this time, the rapid-advance section of the screw's helical groove comes into play. Since its surface has four planes, each with a fixing groove, the rapid-advance section can quickly screw into the mounting hole during rotation. Simultaneously, the arc-shaped guide head... Nylon anti-friction strips are embedded in the groove. When the screw head contacts the mounting component, the nylon anti-friction strips reduce friction, making it easier for the screw head to enter the mounting position and accelerating the initial screwing speed. When the screw passes through the mounting hole and is at the bottom of the mounting hole, the claw mechanism is sleeved on the screw. At this time, the support ring is located outside the fast-forward section of the spiral groove. Eight springs are evenly distributed in pairs inside the support ring and outside the four fixing plates. By manually or with the help of tools, the ends of the four fixing plates away from the springs are inserted into the fixing grooves opened on the four planes of the fast-forward section of the spiral groove. The elastic force of the springs allows the fixing plates to be stably locked in the fixing grooves. Upon reaching a certain limit and providing guidance, the screw continues to rotate, further tightening the fully threaded locking section against the threads in the mounting hole to achieve a fastening effect. During rotation, the fixing plate of the chuck mechanism acts as an auxiliary guide and prevents the screw from shaking within the mounting hole, ensuring stability during the locking process. At this point, the anti-loosening ring comes into play. Made of copper alloy, its inner surface has serrated threads that match the fully threaded locking section. During screw locking, the anti-loosening ring and the threads of the fully threaded locking section mesh together. When the screw is subjected to external forces such as vibration, the anti-loosening ring prevents the screw from being loosened. Loosening ensures the fastener's tightening effect. If further tightening with a nut is required, the nut can be screwed into the outside of the screw until the desired tightness is achieved. At this point, the support ring of the claw mechanism is located at the top of the nut, and the structure of the spring and fixing plate can also limit and prevent loosening of the nut to a certain extent. The spiral groove fast-forward section, together with the nylon anti-friction strip in the arc-shaped guide groove, enables the screw to be quickly and initially screwed in. After the claw mechanism is installed at the bottom of the mounting hole, it plays an auxiliary guiding and stabilizing role in the subsequent locking process, ensuring both the function of quick installation and improving the stability of the locking process.

[0020] Secondly, the installation method of the claw mechanism of this utility model is relatively simple. Installation can be completed by inserting the fixing plate into the fixing groove, which is convenient to operate. Attached Figure Description

[0026] 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.

[0027] This utility model provides the following technical solution:

[0028] Example 1

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 The stainless steel threaded fastener, which is easy to install quickly, includes a screw 1 and a screw head 2. The screw 1 includes a fully threaded locking section 101, a spiral groove fast-forward section 102 and a tapered guide head 103. The surface of the fully threaded locking section 101 is fitted with an anti-loosening ring 104. The top of the screw head 2 is provided with an internal hexagonal drive groove 201. Two arc-shaped guide grooves 202 are symmetrically provided on the side wall of the screw head 2. A claw mechanism 3 is provided on the outside of the screw 1.

[0030] Specifically, the anti-loosening ring 104 is made of copper alloy, and the inner surface of the anti-loosening ring 104 is provided with a sawtooth thread that matches the fully threaded locking section 101.

[0031] Specifically, the surface of the spiral groove fast-forward section 102 has four planes, and each of the four planes has a fixing groove.

[0032] Specifically, a nut 105 is threaded onto the outer side of the screw 1.

[0033] Specifically, a magnetic element is provided at the bottom of the internal hexagonal drive groove 201, and a nylon friction-reducing strip is embedded in the arc-shaped guide groove 202.

[0034] Through the above technical solution, the anti-loosening ring 104 is made of copper alloy, and the sawtooth thread on its inner surface tightly engages with the thread of the full thread locking section 101, which can effectively prevent the screw 1 from loosening when subjected to external forces such as vibration. At the same time, after the nut 105 is installed, the claw mechanism 3 can also play a certain role in limiting and preventing loosening of the nut 105, thereby enhancing the anti-loosening performance and reliability of the entire fastening system. The magnetic element set at the bottom of the internal hexagonal drive groove 201 can attract the wrench and prevent the wrench from slipping during the installation process, thereby improving the stability and safety of operation.

[0035] Example 2

[0036] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 Furthermore, based on Embodiment 1, the following is obtained: the claw mechanism 3 includes a support ring 301, a spring 302 is fixedly connected to the inner side of the support ring 301, and a fixing plate 303 is fixedly connected to the end of the spring 302 away from the support ring 301.

[0037] Specifically, the support ring 301 is located on the outside of the spiral groove fast-forward section 102 and the top of the nut 105, respectively. There are eight springs 302 and four fixing plates 303. The eight springs 302 are evenly distributed in pairs on the inside of the support ring 301 and on the outside of the four fixing plates 303. The ends of the four fixing plates 303 away from the springs 302 are respectively inserted into the fixing grooves opened on the four planes of the spiral groove fast-forward section 102.

[0038] With the above technical solution, the installation of the claw mechanism 3 is relatively simple. Installation can be completed by inserting the fixing plate 303 into the fixing groove, which is convenient to operate.

[0039] In use, insert the tapered guide head 103 into the mounting hole, guide the screw 1 to the position, and use an internal hex wrench that matches the internal hex drive groove 201 to insert the wrench into the internal hex drive groove 201. Since the bottom of the internal hex drive groove 201 is equipped with a magnetic element, it can attract the wrench and prevent the wrench from slipping during installation, thus improving the stability of operation. Rotate the wrench to drive the screw head 2 and the screw 1 to rotate. At this time, the spiral groove fast-forward section 102 of the screw 1 comes into play. Since its surface has four planes, and each of the four planes has a fixing groove, the spiral groove fast-forward section 102 can quickly screw into the mounting hole during rotation. At the same time, the arc-shaped guide groove 202 is embedded with nylon. The friction-reducing strip, made of nylon, reduces friction when the screw head 2 contacts the mounting component, making it easier for the screw head 2 to enter the mounting position and accelerating the initial screwing speed. When the screw 1 passes through the mounting hole and is at the bottom of the mounting hole, the claw mechanism 3 is fitted onto the screw 1. At this time, the support ring 301 is located outside the spiral groove fast-forward section 102. The eight springs 302 are evenly distributed in pairs inside the support ring 301 and outside the four fixing plates 303. By manually or with the aid of tools, the ends of the four fixing plates 303 away from the springs 302 are respectively inserted into the fixing grooves opened on the four planes of the spiral groove fast-forward section 102. The elastic force of the springs 302 allows the fixing plates 303 to be stably locked in the fixing grooves, playing a role in... The screw 1 continues to rotate, providing a fixed limit and guide function, further tightening the fully threaded locking section 101 into the thread in the mounting hole, thus achieving a fastening effect. During rotation, the fixing plate 303 of the chuck mechanism 3 plays an auxiliary guiding role and prevents the screw 1 from shaking in the mounting hole within the fixing groove, ensuring the stability of the locking process. At this time, the anti-loosening ring 104 comes into play. The anti-loosening ring 104 is made of copper alloy, and its inner surface is provided with a sawtooth-shaped thread that matches the fully threaded locking section 101. During the locking process of the screw 1, the anti-loosening ring 104 and the thread of the fully threaded locking section 101 mesh with each other. When the screw 1 is subjected to external forces such as vibration, the anti-loosening ring 104 can prevent the screw 1 from loosening. To ensure the fastening effect of the fastener, if further tightening is required using nut 105, nut 105 can be screwed into the outside of screw 1 until the required tightness is achieved. At this time, the support ring 301 of the claw mechanism 3 is located at the top of nut 105. The structure of spring 302 and fixing plate 303 can also limit and prevent loosening of nut 105 to a certain extent. The spiral groove fast advance section 102, together with the nylon anti-friction strip in the arc guide groove 202, realizes the rapid initial screwing of screw 1. After the claw mechanism 3 is installed at the bottom of the mounting hole, it plays an auxiliary guiding and stabilizing role in the subsequent locking process, which not only ensures the function of rapid installation, but also improves the stability of the locking process.

[0040] 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 may 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.
