Description

Technical Field

[0001] This utility model relates to the field of metal fastener technology, and in particular to a metal fastener that is easy to rotate. Background Technology

[0002] Metal fasteners are key mechanical components made of metal materials, mainly used to reliably connect or fix two or more parts together. They achieve their connection function through mechanical force and are widely used in almost all industrial fields such as construction, machinery, electronics, and transportation. Their core function is to transfer loads, bear stress, maintain structural stability and precise relative position. There are many types of metal fasteners, but they all share the common characteristic of relying on the strength, toughness and durability of the metal itself to achieve a strong and lasting connection. The connection method can be detachable (such as threaded fit) or permanent (such as riveting).

[0003] In existing technologies, when connecting components using metal fasteners, it is usually necessary to manually screw the screws into the holes. However, the smooth outer surface of the nut results in insufficient effective friction when the operator holds it, making it difficult to transmit torque, significantly increasing rotational resistance, and reducing installation and disassembly efficiency. Furthermore, screw heads are generally designed with only a single type of drive groove (such as slotted or Phillips head), forcing the use of specific matching tools, greatly limiting the convenience and flexibility of operation. Therefore, we urgently need a metal fastener that is easy to rotate to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem that rotating fasteners in the prior art is laborious and requires specific matching tools during operation, and to propose a metal fastener that is easy to rotate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rotatable metal fastener includes a bolt body, which mainly consists of a screw and a screw head, and further includes: a circular rod integrally formed with the end of the screw head, the circular rod having a plug-in portion for adapting to a tool end; at least two sets of arc-shaped protrusions integrally formed with the side wall of the screw head, the multiple sets of arc-shaped protrusions being arranged in a ring at equal intervals on the side wall of the screw head; and a conical head integrally formed with the end of the screw for guidance.

[0007] To facilitate the rotation of the bolt, preferably, the screw head is provided with a circular hole for inserting a lever. When the lever is inserted into the circular hole and rotated, the screw head and the screw rod rotate accordingly.

[0008] To improve friction on the screw head, preferably, an anti-slip pad for increasing friction is fixedly installed on the arc-shaped protrusion.

[0009] To make it easier for operators to twist, the height of the arc-shaped protrusion is further specified to be between 2mm and 5mm.

[0010] To accommodate a variety of tools, the connector preferably includes a hexagonal groove on the circular rod for accommodating a hexagonal wrench, and the bottom wall of the hexagonal groove has a Phillips head groove for accommodating a screwdriver.

[0011] To provide better guidance, the cross-sectional projection shape of the cone is preferably triangular.

[0012] Compared with the prior art, this utility model provides a metal fastener that is easy to rotate, and has the following beneficial effects:

[0013] 1. This easily rotating metal fastener features a circular hole located on the screw head. After the screw is inserted into the limiting hole on the component, a matching actuating rod can be inserted into the circular hole. The actuating rod is round, and the operator can rotate it to make the screw rotate and be screwed into the limiting hole. This facilitates the rotation of the metal fastener and improves installation efficiency.

[0014] 2. This easily rotating metal fastener, with its hexagonal and Phillips head grooves, addresses situations where the screw cannot be turned by hand due to high torque when connecting to a component. In such cases, appropriate tools, such as hex wrenches or screwdrivers, can be selected to assist the operator in installation, thus expanding its application range and improving the applicability of the metal fastener.

[0015] 3. This easy-to-rotate metal fastener, with its arc-shaped protrusion and the accompanying anti-slip pad, increases friction with the operator's hand without making the overall size of the screw head too large, allowing it to be used in confined spaces. The arc-shaped protrusion also makes it easier and more convenient for the operator to rotate the screw head, ensuring a rotational assist effect and effectively improving installation and disassembly efficiency.

[0016] 4. This easily rotating metal fastener, with its tapered head, can guide the screw during installation, facilitating quick insertion of the screw into the mounting hole of the component.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model makes it easier and more convenient for operators to rotate fasteners, effectively improves installation and disassembly efficiency, and expands the adaptability to tools.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Example

[0025] Reference Figures 1-4 A rotatable metal fastener includes a bolt body 1, which mainly consists of a screw and a screw head. The screw head has a circular hole 5 for inserting a lever. When the lever is inserted into the circular hole 5 and rotated, the screw head and screw rotate accordingly. Here, the screw head is hexagonal, which makes it easy to tighten with a wrench. The screw has threads, and the circular hole 5 is located on the screw head. When the screw is inserted into the limiting hole on the component, the matching lever can be inserted into the circular hole 5. The lever is round. When the operator rotates the lever, the screw can rotate accordingly, so that the screw is screwed into the limiting hole, which makes it easier for the operator to rotate the metal fastener and improves the installation efficiency.

[0026] It also includes a circular rod 2 integrally formed with the end of the screw head. The circular rod 2 is provided with a plug-in part for adapting to the end of a tool. The plug-in part includes a hexagonal groove 7 formed on the circular rod 2 for adapting to a hex wrench. The bottom wall of the hexagonal groove 7 is provided with a cross groove 8 for adapting to a screwdriver. Here, when the screw is connected to the component, there may be a situation where it cannot be turned by hand due to a large torque. At this time, the corresponding tool, such as a hex wrench or screwdriver, can be selected according to the needs to assist the operator in installation, which can expand its application range and improve the applicability of metal fasteners.

[0027] At least two sets of arc-shaped protrusions 3 are integrally formed with the sidewall of the screw head. Multiple sets of arc-shaped protrusions 3 are arranged in a ring at equal intervals on the sidewall of the screw head. Anti-slip pads 6 for improving friction are fixedly installed on the arc-shaped protrusions 3. The height of the arc-shaped protrusions 3 ranges from 2mm to 5mm. Here, the height of the arc-shaped protrusions 3 is 4mm. At this height, in conjunction with the anti-slip pads 6, the friction with the operator's hand can be improved, and the overall volume of the screw head will not be too large, so it can be used in a confined space. In addition, the arc-shaped protrusions 3 make it easier and more convenient for the operator to rotate the screw head, ensuring the rotation assistance effect and effectively improving the installation and disassembly efficiency.

[0028] A conical head 4, integrally formed with the end of the screw, is used for guidance. The cross-sectional projection shape of the conical head 4 is triangular. Here, the conical head 4 can play a guiding role when the screw is installed, so that the screw can be quickly inserted into the mounting hole of the component.

[0029] In this utility model, the operator inserts the conical tip 4 on the screw into the mounting hole of the component. The operator can rotate the screw through the arc-shaped protrusion 3 on the screw head to make the screw turn into the mounting hole. Alternatively, an external actuating rod can be inserted into the circular hole 5 on the screw head, and the screw can also be turned into the mounting hole by rotating the actuating rod. When the screw encounters a large torque in the mounting hole, a hex wrench or screwdriver can be used in conjunction with the hexagonal groove 7 and the cross groove 8 to screw the screw into the mounting hole using an external adapter tool, thereby completing the installation. This further improves the convenience of rotating the bolt body 1.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
