Description

Technical Field

[0001] The utility model belongs to the technical field of hexagonal head bolts, and more specifically, particularly relates to a hexagonal head bolt capable of avoiding thread slippage. Background Art

[0002] Thread slippage refers to the situation in which the threads of a threaded connection cannot be tightened because the threads are worn due to excessive force or other reasons, making it impossible for the threads to engage. Bolt thread slippage is mainly caused by excessive force, excessive deviation or excessive wear of the device. In order to keep the bolt in normal use, a hexagonal head bolt that can avoid thread slippage is needed.

[0003] For example, a hexagonal head bolt that can avoid thread slippage is proposed in application number: 202322657234.0, including a screw rod, a screw head is fixedly connected to the top of the screw rod, a connecting column is fixedly connected to the top of the screw head, an adjustment mechanism that can be easily used to prevent thread slippage is arranged at the bottom of the screw head, and a protective mechanism that can protect the bolt is arranged at the top of the screw head. The hexagonal head bolt that can avoid thread slippage can ensure that the bolt position is correct by fitting the balance block at the bottom with the contact surface, and at the same time, the inclined block at the bottom can be better inserted into the threaded hole, which can effectively prevent thread slippage caused by the deviation of the bolt position. At the same time, when the bolt is rotated to the maximum position, it cannot be rotated any more due to the support of the telescopic rod, which can prevent the bolt from being over-tightened and causing thread slippage. At the same time, a protective mechanism can be installed on the surface of the screw head to protect the bolt and prevent it from being exposed to the outside and rusting, causing jamming, etc.

[0004] Based on the findings in the prior art, hexagonal head bolts are usually installed directly, which makes the bolts prone to thread slippage due to over-deflection. When installing the above-mentioned hexagonal head bolts, in order to prevent the thread slippage, a docking structure is provided to assist in its treatment. However, since the docking structure needs to be provided on the bolt body, it increases the production cost and complicates the use process of the bolt. Utility Model Content

However, because the docking structure needs to be set on the bolt body, it increases the production cost and complicates the use process of the bolt.

[0006] In a first aspect of the present disclosure, a hexagonal head bolt capable of preventing thread stripping is provided, which is achieved by the following specific technical means:
