Problems solved by technology

[0002] A bolt is a common mechanical part, consisting of a bolt head and a screw rod. The outer wall of the bolt head is set into a polygonal shape according to the needs. The most common one is a hexagonal bolt head. The screw part is provided with threads. When the bolt is used, The two objects are connected by bolts. Bolts are essentially used to fasten two parts with through holes. They are widely used in the mechanical field, but the following problems will occur in the actual operation process and have been fixed. The exposed part of the bolt is often accidentally broken by other objects, resulting in the remaining screw of the bolt is still fixed in the threaded through hole, resulting in the failure of the fixed mechanical components to be disassembled smoothly. Usually, people use destructive methods to remove the screw. Drilling out of it, this operation is not only time-consuming and laborious, but also will destroy the internal thread of the through hole, and indirectly cause the fixed structure of the mechanical component to fail

Embodiment Construction

[0011] The present invention will be described in further detail below by means of specific embodiments:

[0012] The reference signs in the accompanying drawings of the description include: central rod head 11 , central rod column 12 , bolt head 21 , screw rod 22 , hollow cavity 23 , and sealing layer 3 .

[0013] The embodiment is basically as attached figure 1 and figure 2 Shown: A bolt that can be quickly taken out when broken, including a bolt head 21 and a screw rod 22 integrally formed with the bolt head 21. A hollow cavity 23 is provided from the end of the bolt head 21 to the end of the screw rod 22. The cross section of the hollow cavity 23 It is hexagonal, and the diameter of the circumscribed circle of the hollow cavity 23 is 4mm. The bolt of this program also includes a central rod, which includes a central rod head 11 with the same cross-section as the bolt head 21 and a central rod column 12 with the same cross-section as the hollow cavity wall , the central ...

Abstract

The invention discloses a bolt capable of being taken out rapidly after being broken. The bolt comprises a bolt head and a screw rod integrally formed with the bolt head. A through hollow cavity is formed from the end of the bolt head to the end of the screw rod. The cross section of the hollow cavity is in a hexagonal shape. The bolt further comprises a center rod. The center rod comprises a center rod head with the section identical with that of the bolt head and a center rod pillar with the section identical with that of the wall of the hollow cavity. The center rod pillar is in sliding fit with the hollow cavity, and the center rod head is attached to the bolt head in a sealed manner. The bolt has the beneficial effects that the bolt is applied to connection of objects, when the bolt breaks, the broken bolt can be rapidly taken out through a hexagon wrench, and the time for taking out the bolt is effectively saved.

Description

technical field [0001] The invention relates to a bolt, in particular to a bolt that can be quickly taken out when broken. Background technique [0002] A bolt is a common mechanical part, consisting of a bolt head and a screw rod. The outer wall of the bolt head is set into a polygonal shape according to the needs. The most common one is a hexagonal bolt head. The screw part is provided with threads. When the bolt is used, The two objects are connected by bolts. Bolts are essentially used to fasten and connect two parts with through holes. They are widely used in the mechanical field, but the following problems will occur during actual operation. The exposed part of the bolt is often accidentally broken by other objects, resulting in the remaining screw of the bolt is still fixed in the threaded through hole, resulting in the failure of the fixed mechanical components to be disassembled smoothly. Usually, people use destructive methods to remove the screw. Drilling out of ...
