Description

High performance bolt

The present invention relates to a high-performance bolt, in particular to a recessed end surface of a bolt head end of the bolt body, and the inner ring wall of the insert groove has a first clamping structure. A protrusion is protruded upward from the bottom of the slot, and the outer circumference of the protrusion has a second clamping structure. The first clamping structure cooperates with the shape of the outer peripheral surface of the driving head of the T-wrench. The second clamping structure cooperates with the shape of the inner circumferential surface of the groove of the end surface of the driving head, and the technology achieves the purpose of preventing any rotation of the bolt and improving the driving torque.

According to the commonly known bolts, it is a relatively well-known and frequently used part. Where the connection between the object and the object is fixed, bolts must be used to lock the two objects to each other, thereby achieving the purpose of connecting and fixing the two objects. For example, assembly of household appliances such as furniture, household appliances, buildings, machines, machinery, and electronic devices, as long as the two components need to be fixed to each other, they are often locked by screws or bolts. It can be seen that bolts are indeed extremely important and indispensable parts in industrial, maintenance and family life.

Furthermore, the conventional bolt is mainly constructed with a bolt head at one end and an external thread adjacent to the other end. The bolt head is provided by a tool such as a screwdriver, a wrench or a clamp to be driven by a force to rotate the bolt, thereby The bolt is locked in the forward direction or reversed to the object. As for the bolt head for the structure of the screwdriver, wrench or jaw positioning, one is to design the bolt head into a polygonal column (commonly a six-sided column), a clamping jaw or a multi-angled wrench or Socket wrench Sleeve on the polygonal cylindrical bolt and apply force to the clamp or wrench to drive the bolt head to rotate, which can drive the bolt forward or reverse. The other is to have a non-circular groove on the end surface of the bolt head, and fit the shape of the screwdriver head or the T-shaped or column-shaped wrench to insert the screwdriver head or the T-shaped or cylindrical wrench into the slot to apply force. A screwdriver or a T-shaped column wrench is used to drive the bolt head to rotate, thereby driving the bolt to rotate forward or reverse. In order to facilitate the general screwdriver or a simple T-shaped or cylindrical wrench to drive the bolt rotation, the most common bolts are non-circular recesses on the end face of the bolt head for the general screwdriver or simple T-shaped or cylindrical wrench embedded positioning. And drive the rotation instead of the circular slot. At present, the most common one is a slot, a cross slot and a hexagon socket. Because of this, if you buy a screwdriver or a wrench at a hardware store, you can use it to drive the rotating bolt. For general purpose bolts, there should be no safety problems. However, for the locking of special objects, such as the scaffolding, the artificial combination rock for rock climbing, the car tires or the exposed components, there is a great risk, because anyone can buy or carry the screwdriver at will. Or T-shaped or cylindrical wrench, can be used to drive the rotating bolt, once the bolt is maliciously released by others, it will cause harm.

In order to prevent the bolt from being loosened by others, a conventional method is known in which the groove of the bolt head is designed into a non-standard shape, some are designed as inner ring gears, and some are designed as triangular grooves like Chinese The Republic of China announced the patent No. M246491. In another conventional manner, although the inner wall of the slot is a hexagonal groove, a cylindrical boss is added at the bottom of the slot, and the inner wall of the slot is a hexagonal groove to ensure the fit. When the hexagonal wrenches are nested with each other, the structure of the above-mentioned one-word, cross, inner ring-toothed ring and triangular groove-shaped recessed groove is better than the driving torque, and the inner hexagonal recessed cylindrical cylindrical column is limited in general. The hex wrench is embedded in the hexagonal hex groove, and the hex wrench has a groove with a cylindrical stud or a groove structure capable of accommodating the stud, that is, a special structure hex wrench can be embedded in the bolt head. Hexagonal recessed groove for driving, so as to achieve sufficient driving force for the hexagonal hexagonal groove and avoid the arbitrarily tightness of others The purpose of total prevention. The insert head of the bolt head has an inner hexagon shape. Although it has a high torsional bearing capacity, the conventional structure is simply designed with a circular stud in the inner hexagonal inlay as a safety design, and the torsion force it can withstand is still limited. It can also be designed as an inner hexagonal groove to accommodate higher torque tolerance and its shape is limited.

In view of the various shortcomings caused by the above-mentioned conventional technologies, the present creator has accumulated rich experience in R&D and design for many years, and actively invested in research and development. After continuous design, trial and experiment, the new research and development results are finally produced.

The main purpose of the present invention is to provide a high-performance bolt, which can not only prevent the dangerous situation caused by maliciously rotating the bolt, but also achieve the effect of improving the driving torque. The technical means for achieving the foregoing objectives includes a bolt body having a tapping end at one end and a carding end at the other end. The clamping end is provided with a bolt head and has an external thread on its circumferential surface. A slot is recessed in the end surface of the bolt head. The slot is embedded in the driver's head of the wrench. The inner ring wall of the recess has a first clamping structure. A protrusion is protruded upward from the bottom of the slot, and the protrusion is embedded in a recess recessed in the end surface of the driving head. The outer peripheral surface of the stud has a second clamping structure. The first clamping structure of the recessed groove cooperates with the shape of the outer peripheral surface of the driving head of the T-shaped wrench. The second clamping structure of the stud is matched with the shape of the inner circumferential surface of the groove.
