Detailed Description
The present invention is described in terms of particular embodiments, other advantages and features of the utility model will become apparent to those skilled in the art from the following disclosure, and it is to be understood that the described embodiments are merely exemplary of the utility model and that it is not intended to limit the utility model to the particular embodiments disclosed. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
According to an embodiment of the present invention, a torsional shear type bolt convenient to disassemble is provided, as shown in fig. 2 to fig. 3, the torsional shear type bolt includes a bolt head 11 and a connecting portion 12 that are integrally connected to each other, one end of the bolt head 11 away from the connecting portion 12 is planar, a part of the surface of the connecting portion 12 is provided with a thread, the bolt head 11 is provided with a force application hole 14 along an axial direction thereof, and the force application hole 14 is a blind hole.
According to the conveniently-disassembled torsional shear type bolt, the force application hole 14 is formed in the bolt head 11 along the axial direction of the bolt, so that when the torsional shear type bolt is disassembled after being installed, a tool can be fixed through the force application hole 14, and when a nut is screwed, the bolt head can be fixed, so that the nut is conveniently screwed, and the torsional shear type bolt is convenient to disassemble.
The force application hole 14 is a hexagon socket hole. The inner hexagonal hole can be matched with a corresponding wrench for use, and is easier to disassemble.
The depth of the force application hole 14 is 0.3-0.8 of the thickness of the bolt head 11. The depth of the force application hole 14 should not be too shallow, so that the risk of slipping out of the tool during fixing is easy to occur, and certainly, should not be too deep so as to avoid affecting the strength of the bolt head 11.
The shape and size of the force application hole 14 correspond to those of a corresponding hexagonal wrench. Since the hexagonal wrench is a common tool, the shape and size of the force application hole 14 can be machined according to the corresponding wrench size, and during machining, a casting process can be directly selected for machining, and machining or other methods can also be adopted for machining.
The axial direction of the force application hole 14 coincides with the axial direction of the bolt head 11. By making the axial direction of the force application hole 14 coincide with the axial direction of the bolt head 11, the strength of the bolt head 11 can be ensured, and the occurrence of cracking can be avoided.
The torsional shear type bolt convenient to disassemble further comprises a plum blossom head 13, and the plum blossom head 13 is connected with the connecting portion 12. Specifically, the connecting portion 12 includes a threaded section 121, and the quincuncial head 13 is connected to the threaded section 121 to facilitate connection of the nut.
Although the utility model has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the utility model. Accordingly, such modifications and improvements are intended to be within the scope of the utility model as claimed.
