[0001] This application belongs to the field of bolts, and particularly relates to an anti-rust external hexagon bolt. Background Art

[0002] Bolts, as fasteners for installing and fixing profiles, are widely used by people. There are many types of bolts used in the existing assembly process. Generally speaking, most of them adopt the structural design of bolt standard parts, that is, each bolt in profile installation is applied in the form of a standard part.

[0003] The existing publication number CN211145051 U discloses an anti-slip external hexagon bolt with a spacer, which includes a screw rod and a screw head. A screw rod is fixedly installed in the middle of the lower surface of the screw head. A nut is threadedly installed on the screw rod. Thread grooves are formed on the surface of the screw rod other than the upper and lower ends, and the thread grooves match the nut. An annular groove is formed on the outer side of the lower surface of the screw head, and an annular gasket is embedded in the annular groove. The annular groove matches the annular gasket, and the lower surface of the annular gasket is lower than the lower surface of the screw head. The annular gasket is located between the upper surface of the nut and the lower surface of the screw head.

[0004] Although the above-mentioned bolt can limit and fix the gasket to make the gasket fixed, the bolt head is easily rusted and corroded when exposed for a long time, resulting in the bolt becoming slippery and difficult to rotate. Summary of the Utility Model

[0005] The purpose of this application is to provide an anti-rust external hexagon bolt for the above-mentioned existing technical problems, which can prevent the bolt head from being rusted and corroded when exposed for a long time, and avoid the bolt from becoming slippery and difficult to rotate.

[0006] This application provides an anti-rust external hexagon bolt, including a screw rod, and further including:

[0007] A hexagon bolt head, which is arranged on the screw rod;

[0008] A protection component, which is installed on the hexagon bolt head

[0009] Wherein, the protection component includes a slot, a protection shell, an insertion block, a fixing component, and a mounting hole. The slot is arranged on the hexagon bolt head, and several slots are provided. The protection shell is sleeved on the hexagon bolt head. The insertion block is installed on the protection shell, and several insertion blocks are provided. When the protection shell is installed on the hexagon bolt head, the insertion block is inserted and matched with the slot. The mounting hole is arranged on the top surface of the protection shell.

[0010] After installation by hexagon bolts, in order to prevent the bolt head from being exposed to the outside for a long time and rusting, the protection shell is sleeved on the hexagon bolt head. At the same time, several insertion blocks on the protection shell are inserted into the corresponding slots in the longitudinal axis direction to limit the position of the protection shell. The protection shell can prevent the bolt head from being exposed to the outside for a long time and rusting, and avoid the bolt from slipping and being difficult to rotate.

[0011] Furthermore, a circular groove is provided on the hexagon bolt head, and a spare jack is provided in the circular groove on the hexagon bolt head.

[0012] With a circular groove provided on the hexagon bolt head and a spare jack provided in the circular groove on the hexagon bolt head, when the hexagon bolt becomes slippery and difficult to rotate due to corrosion and rust, the user can insert a tool into the spare jack to turn the hexagon bolt, avoiding the hexagon bolt from being difficult to remove due to slipping.

[0013] Furthermore, the protection component further includes:

[0014] A top cover, on which a convex block is integrally connected. The convex block on the top cover is inserted through the mounting hole on the protection shell and finally inserted into the spare jack in the circular groove on the hexagon bolt head;

[0015] A locking groove, which is provided on the hexagon bolt head and is arranged at the lower end of the spare jack and communicated with the spare jack;

[0016] A connecting rod, which is installed at the lower end of the convex block on the top cover;

[0017] A locking block, which is set in a cuboid shape and is installed on the connecting rod.

[0018] In order to prevent the bolt head from being exposed to the outside for a long time and rusting, the protection shell is sleeved on the hexagon bolt head. The convex block on the top cover is inserted through the mounting hole on the protection shell and finally inserted into the spare jack in the circular groove on the hexagon bolt head. At this time, the connecting rod on the top cover enters the spare jack, and the locking block on the connecting rod enters the locking groove. At this time, the top cover is rotated clockwise by 45 degrees so that the locking block rotates 45 degrees around the axis of the connecting rod. At this time, the locking block cannot be pulled out of the spare jack to complete the locking of the position of the top cover on the hexagon bolt head. The top cover makes the effect of the protection component covering and protecting the hexagon bolt head better. The cooperation between the locking block and the locking groove makes the top cover more stable and less likely to become loose when covering and protecting the hexagon bolt head.

[0019] Furthermore, the fixing component includes:

[0020] A limiting strip, which is installed on the lower end surface of the top cover;

[0021] A mounting block, which is installed on the limiting strip;

[0022] A limiting groove is provided on the protective housing, and an opening for the installation block to enter is provided at one end of the limiting groove;

[0023] A sliding groove is provided on the protective housing. The sliding groove is provided at the lower end of the limiting groove and communicates with the rotating groove.

[0024] When it is necessary to fix the position of the protective housing, when the convex block on the top cover is inserted through the mounting hole on the protective housing and finally inserted into the spare jack in the circular groove on the hexagon bolt head, the mounting strip is also inserted into the opening at one end of the sliding groove. At this time, the limiting strip is inserted into the limiting groove to prevent the protective housing from shifting in position during installation. When the top cover is rotated clockwise by 45 degrees for position fixing, the installation block is simultaneously driven to rotate in the sliding groove. When the top cover stops rotating, the installation block abuts against the groove wall at the end of the sliding groove without an opening. At this time, it cannot be pulled out from the sliding groove. When the top cover has completed position locking with the hexagon bolt head, the position locking of the top cover and the protective housing prevents the protective housing and the top cover from detaching from the hexagon bolt head, making the protection and shielding effect of the protection component on the bolt better. At the same time, when it is necessary to disassemble the protective housing and the top cover, only need to rotate the top cover counterclockwise to pull out the protective housing and the top cover from the hexagon bolt head. The fixing component makes the installation and disassembly of the protective housing and the top cover on the hexagon bolt head more convenient and efficient.

[0025] Furthermore, the fixing component further includes:

[0026] Rotating bars, which are installed on the top cover, and several rotating bars are provided.

[0027] Furthermore, the fixing component further includes rotating bars, which are installed on the top cover, and several rotating bars are provided. The rotating bars can make it easier for the user to rotate the top cover to install and disassemble the protective housing and the top cover, and it is easier to rotate and pull out the top cover.

[0028] Furthermore, friction lines are provided on the rotating bars.

[0029] Due to the friction lines provided on the rotating bars, the friction lines can enable the user to more quickly touch and identify the rotation and insertion / removal of the top cover by the rotating bars when touching the top cover for rotation. At the same time, the friction lines can increase the friction force between the rotating bars and the user's hand, making it less likely for the user to drop the top cover when rotating and inserting / removing the top cover.

[0030] The beneficial effects of this application are:

[0031] 1. The protective housing can prevent the bolt head from being exposed to the outside for a long time and rusting and corroding, and avoid the bolt from becoming slippery and difficult to rotate;

[0032] 2. When the hexagonal bolt becomes difficult to turn due to corrosion and rusting and slips, the user can insert a tool into the spare jack to turn the hexagonal bolt to avoid the difficulty of removing the hexagonal bolt due to slipping.

[0033] 3. The top cover makes the protection component better shield and protect the hexagonal bolt head, and the cooperation between the lock block and the lock groove makes the top cover more stable and less likely to become loose when shielding and protecting the hexagonal bolt head.
