Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bolts, in particular to a hexagonal flange bolt. Background Art
[0002] Bolts are indispensable in daily life and industrial production, and are also called the rice of industry. Bolts are a general term for fasteners. Bolts are tools that use the physical and mathematical principles of the circular rotation of the inclined plane and the friction of an object to gradually tighten objects and mechanical parts. However, if the objects and mechanical parts are only locked by the circular rotation of the inclined plane and the friction, they are very likely to fall off due to vibration, external force factors or the inclination angle of the thread is greater than the self-locking angle. The falling off of the bolts is very likely to cause damage to the mechanical structure and even cause safety accidents. In addition, hexagonal flange bolts are generally installed by wrenches or torque wrenches, which are not suitable for small spaces. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a hexagonal flange bolt with an additional fastening structure and convenient for tightening in a narrow space.
[0004] The technical solution adopted by the utility model is a hexagonal flange bolt, comprising a bolt body, a flange is fixed at one end of the bolt body, a hexagonal boss is fixed at one side of the flange, a plurality of cylinders are fixed at one side of the hexagonal boss, a hexagonal tightening head is fixed at one side of the cylinder, a plurality of spring washers are fixed at one side of the flange, a plurality of grooves are opened on the side of the bolt body near the flange, and a spring steel sheet is fixed at one side of the groove.
[0005] As a further solution of the utility model: threaded connection teeth are fixed on the side of the bolt body for normal connection.
[0006] As a further solution of the utility model: there are six cylinders in total, and the six cylinders are evenly fixed on one side of the hexagonal boss. The six cylinders are spaced a certain distance apart and can be inserted through other rigid plug rods to facilitate tightening the bolt body in a narrow space.
[0007] As a further solution of the utility model: there are four spring washers in total, the spring washers include a connecting steel sheet, one end of the connecting steel sheet is fixed with a clamping steel sheet, the clamping steel sheet is parallel to the flange plate, and can play a tightening role.
[0008] As a further solution of the utility model: the thickness of the spring steel sheet is equal to the depth of the groove, which can play a tightening role when performing threaded deep hole connection to prevent the bolt body from reversing.
[0009] Compared with the prior art, the advantages of the utility model are as follows: the patent adds six cylindrical structures. When installing in a narrow space, due to the limited operating space, a wrench or a torque wrench is generally unable to tighten deeply. By using a rigid long rod inserted into the gap between the cylinders and then rotating the rigid long rod, the bolt can also be tightened. The addition of a spring gasket structure and a spring steel sheet further enhances the tightening ability of the bolt and prevents it from loosening and falling off.

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] The utility model provides a technical solution to solve the existing problems raised in the background technology.
[0019] Combined with Figure 1-4It can be known that the bolt includes a bolt body 1, a flange 2 is fixed at one end of the bolt body 1, a hexagonal boss 3 is fixed on one side of the flange 2, a plurality of cylinders 4 are fixed on one side of the hexagonal boss 3, a hexagonal tightening head 5 is fixed on one side of the cylinder 4, and a plurality of spring washers 6 are fixed on one side of the flange 2, which can make the connection of the bolt body 1 tighter, and a plurality of grooves 1.1 are opened on the side of the bolt body 1 near the flange 2, and a spring steel sheet 7 is fixed on one side of the groove 1.1, which can prevent the bolt body 1 from reversing when the deep groove connection is performed.
[0020] A threaded connection tooth 1.2 is fixed on the side of the bolt body 1 for normal connection; there are six cylinders 4, which are evenly fixed on one side of the hexagonal boss 3. The six cylinders 4 are spaced a certain distance apart and can be inserted through other rigid plug rods to facilitate tightening the bolt body 1 in a narrow space; there are four spring washers 6, which include a connecting steel sheet 6.1, and a clamping steel sheet 6.2 is fixed at one end of the connecting steel sheet 6.1. The clamping steel sheet 6.2 is parallel to the flange 2 and can play a tightening role; the thickness of the spring steel sheet 7 is equal to the depth of the groove 1.1, which can play a tightening role when performing a threaded deep hole connection to prevent the bolt body 1 from reversing.
[0021] The working principle of the present application is as follows: when installing the bolt, one end of the bolt body 1 is inserted into the connecting through hole and then fixed by the nut. When tightening, the spring gasket 6 will be continuously pressed, so that the connecting steel sheet 6.1 is continuously squeezed, giving the bolt body 1 an outward force, thereby increasing the friction between the bolt body 1 and the nut to prevent it from falling off; when installing the bolt body 1 in a deep groove, the spring steel sheet 7 will also be squeezed while tightening, so that it will exert a force on the inner side of the deep groove, increasing the friction of the bolt body 1, making it difficult for the bolt body 1 to fall off; when installing in a narrow range, due to limited operating space, a wrench or a torque wrench is generally unable to tighten deeply. By using a rigid long rod inserted in the gap between the cylinders 4 and then rotating the rigid long rod, the bolt can also be tightened.
[0022] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
