Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically fastening anchors. Background Technology

[0002] Fastening anchors are commonly used to anchor various pipeline supports or as fasteners for connecting and installing other objects. When fastening anchors are used on the edge of the storage area at the rear of an all-terrain vehicle, they are installed through the pre-drilled holes in the vehicle. After installation, they provide a fulcrum for securing ropes, allowing users to use ropes to secure cargo in the rear storage area of ​​the all-terrain vehicle, ensuring that the cargo does not fall off during driving.

[0003] Currently, most fastening anchors on the market are fixed by the principle of hard sponge expansion. These anchors have low strength and can withstand less tensile force. When all-terrain vehicles travel on bumpy roads, these anchors are prone to falling off. They also have poor durability and are prone to hardening, deformation and damage, which affects the safety of goods in the storage area during driving.

[0004] Therefore, we designed a fastening anchor to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a fastening anchor to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides a fastening anchor, including a fixing member, a washer fixedly connected to the top of the fixing member, a handle rotatably connected to the top of the washer, a threaded hole provided inside the handle, a threaded thread provided inside the threaded hole, a stud inserted into the handle, the stud being threadedly connected to the threaded hole through the thread, and a mechanical blade fixedly connected to the bottom of the fixing member, the bottom of the stud being movably abutting against the mechanical blade.

[0007] Furthermore, a support base is fixedly connected to the bottom of the stud, and a protrusion is fixedly connected to one side of the support base.

[0008] Furthermore, the support base is configured to be tapered.

[0009] Furthermore, the mechanical blades are provided in a quantity of four, and all four mechanical blades are fixedly connected to the bottom of the fixing member.

[0010] Furthermore, the top of the handle has a socket that communicates with a threaded hole, and the stud is rotatably inserted into the socket.

[0011] Furthermore, the fixing member has a sliding groove inside, and the stud is movably disposed inside the sliding groove.

[0012] Furthermore, the number of the protrusions is set to two, and the two protrusions are symmetrically arranged on both sides of the support base.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by placing the fixing component and mechanical blade into the reserved mounting hole, the handle is rotated. When the handle rotates on the top of the pad, the stud inside the handle is connected to the threaded section of the insertion hole, driving the stud to move vertically. The support seat and protrusion at the bottom of the stud move synchronously with the stud. The conical surface of the support seat gradually squeezes the mechanical blade. Multiple mechanical blades are simultaneously opened by the support seat, increasing the contact area between the mechanical blade and the mounting hole. The more times the stud rotates, the greater the force of the mechanical blade expanding and squeezing the mounting hole, and the greater the tensile force that the fastening anchor can withstand.

[0019] 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.

[0020] Please see Figure 1-4This utility model provides a technical solution: including a fixing member 1, a gasket 2 fixedly connected to the top of the fixing member 1, a handle 3 rotatably connected to the top of the gasket 2, a threaded hole 6 inside the handle 3, a thread inside the threaded hole 6, a stud 4 inserted into the handle 3, the stud 4 being threadedly connected to the threaded hole 6, a mechanical blade 7 fixedly connected to the bottom of the fixing member 1, the bottom of the stud 4 being movably abutting against the mechanical blade 7, a support base 9 fixedly connected to the bottom of the stud 4, a protrusion 10 fixedly connected to one side of the support base 9, the support base 9 being tapered, and four mechanical blades 7 being fixedly connected to the bottom of the fixing member 1.

[0021] It should be noted that the support base 9, mechanical blades 7, and other components are all made of nylon PA6. Nylon PA6 possesses a certain degree of rigidity, allowing mechanical strength to replace elastic deformation. The fixing force is achieved through the mechanical engagement between the mechanical blades 7 and the mounting hole wall. Nylon PA6 material enhances pull-out resistance at the material level. Furthermore, nylon PA6 material exhibits certain chemical stability, preventing material aging issues caused by outdoor environments. This ensures the anchor can operate reliably for a long time under complex working conditions such as bumpy rides and rain in all-terrain vehicles. The rigidity of nylon PA6 also allows for adjustability during use. Operators can adjust the expansion force of the support base 9 on the mechanical blades 7 by rotating the handle 3 and adjusting the number of rotations of the stud 4. This allows users to flexibly adjust the fixing strength of the anchor according to the weight of the cargo. The threaded hole 6 is located at the center of the handle 3. The handle 3 is polygonal in shape and has an integrally formed anti-slip texture on the edge of the handle 3, which makes it easier for the staff to grip the handle 3 and improves the ease of rotation of the handle 3. The stud 4 at the center of the handle 3 is conical. By rotating the handle 3 at the top of the fixing part 1, the stud 4 will rotate up and down, forming an internal compression of the mechanical blades 7 around the perimeter. This causes the mechanical blades 7 to expand and thus fix the installation hole position. The more times the stud 4 rotates, the greater the force of the mechanical blades 7 expansion and compression, and the greater the tensile force that the fastening anchor can withstand.

[0022] In practice, the worker can insert the fixing part 1 and the mechanical blade 7 into the reserved mounting hole. Then, the user can press down on the pad 2 and hold the handle 3 with the other hand to rotate the handle 3. When the handle 3 rotates on the top of the pad 2, the stud 4 inside the handle 3 is connected to the threaded section of the insertion hole 5, which will drive the stud 4 to move vertically inside the handle 3. When the stud 4 moves vertically, the support seat 9 and the protrusion 10 at the bottom of the stud 4 move synchronously with the stud 4. While the support seat 9 moves vertically downward, the conical surface of the support seat 9 presses against the mechanical blade 7, increasing the contact area between the support seat 9 and the mechanical blade 7. Multiple mechanical blades 7 are simultaneously opened by the support seat 9, increasing the contact area between the mechanical blade 7 and the mounting hole. The more times the stud 4 rotates, the greater the force of the mechanical blade 7 expanding and pressing against the mounting hole, and the greater the tensile force that the fastening anchor can withstand.

[0023] See Figure 2 The top of the handle 3 has an insertion hole 5, which is connected to the threaded hole 6. The stud 4 is rotatably inserted into the inside of the insertion hole 5. The inside of the fixing part 1 has a sliding groove 8, and the stud 4 is movably disposed inside the sliding groove 8.

[0024] By providing an insertion hole 5 at the center of the handle 3, and connecting the insertion hole 5, threaded hole 6, and sliding groove 8, the stud 4 can move within the insertion hole 5, threaded hole 6, and sliding groove 8. This allows the stud 4 to rotate simultaneously with the handle 3 due to the threaded connection when the handle 3 is rotated, and to move vertically during rotation, thus facilitating contact between the outer surface of the support base 9 and the mechanical blade 7.

[0025] See Figure 4 There are two protrusions 10, which are symmetrically arranged on both sides of the support base 9.

[0026] By setting protrusions 10, which are symmetrically arranged on both sides of the support base 9 with the vertical axis of the support base 9 as the center, the protrusions 10 are slidably connected to the grooves formed between the two mechanical blades 7. When the support base 9 moves vertically with the stud 4, the protrusions 10 will slide in the grooves between the mechanical blades 7. The sliding cooperation between the protrusions 10 and the grooves provides a precise guide trajectory for the movement of the support base 9, avoids the stud 4 from shifting laterally when it rotates inside the handle 3, and ensures that the conical surface of the support base 9 can evenly squeeze the mechanical blades 7 around it. When the stud 4 rotates and drives the support seat 9 to move downward, the protrusion 10 will slide smoothly along the inner wall of the groove to prevent the support seat 9 from tilting, thereby ensuring that the expansion force of the four mechanical blades 7 is consistent. The sliding contact surface of the protrusion 10 can be treated with wear resistance (such as the surface hardening process of nylon PA6 material). This is existing technology, so it will not be described in detail here. When the support seat 9 squeezes the mechanical blades 7, it can evenly transmit the axial force to each mechanical blade 7, which can avoid excessive local stress concentration, and facilitate the improvement of the stability of the stud 4 and the support seat 9 when sliding. It also facilitates the support seat 9 to open up multiple mechanical blades 7 at the same time, so that the mechanical blades 7 expand and squeeze the inner wall of the mounting hole, thereby increasing the tensile force that the fastening anchor can withstand.

[0027] Working principle: When using the device, the operator can insert the fixing part 1 and the mechanical blade 7 into the reserved mounting hole. Then, the user can press the pad 2 and hold the handle 3 with the other hand to rotate the handle 3. When the handle 3 rotates on the top of the pad 2, the stud 4 inside the handle 3 is connected to the threaded section of the insertion hole 5, which will drive the stud 4 to move vertically inside the handle 3. When the stud 4 moves vertically, the support seat 9 and the protrusion 10 at the bottom of the stud 4 move synchronously with the stud 4. While the support seat 9 moves vertically downward, the conical surface of the support seat 9 presses against the mechanical blade 7, increasing the contact area between the support seat 9 and the mechanical blade 7. Multiple mechanical blades 7 are simultaneously opened by the support seat 9, increasing the contact area between the mechanical blade 7 and the mounting hole. The more times the stud 4 rotates, the greater the force of the mechanical blade 7 expanding and pressing against the mounting hole, and the greater the tensile force that the fastening anchor can withstand.
