[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] Depend on Figure 1 , Figure 2 and Figure 3The utility model provides a rust-proof locking screw for an engineering guardrail. The screw body 100 is in a vacuum setting. The upper and lower side walls of the inner cavity of the screw body 100 are rotatably connected with an adjusting screw 101. Raising the adjusting screw 101 facilitates driving the pushing block 102 to move. The outer wall of the adjusting screw 101 is threaded with a pushing block 102. The pushing block 102 facilitates pushing the sealing ring 103 to deform the sealing ring 103. A sealing groove is provided on the outer wall of the screw body 100. The sealing groove is spirally set. The inner wall of the screw body 100 is slidably connected with a sealing ring 103. The outer wall of the sealing ring 103 is fixedly connected with a sealing strip 104. The same sealing strip 104 is convenient for moving and deforming to fill the gap, which is beneficial for sealing. The sealing strip 104 is located in the inner cavity of the sealing groove. The sealing ring 103 and the sealing strip 103 are both made of rubber material. The sealing ring 103 is located on the top wall of the inner cavity of the screw body 100.

[0021] In the present embodiment: the engineering guardrail is installed and fixed by the screw body 100. After the installation is completed, the pushing block 102 is driven to move by rotating the adjusting screw 101. The pushing block 102 moves to push the sealing ring 103, so that the sealing ring 103 is expanded. The movement of the sealing ring 103 drives the sealing strip 104 to move, so that the sealing strip 104 moves outward to produce deformation to seal the gap and prevent the outside water vapor from entering. The device can easily seal the gap and prevent the screw body 100 from rusting due to water vapor, which is beneficial to improving the rust-proof performance of the screw body 100.

[0022] It should be noted that a rotating groove is provided on the top wall of the screw body 100, and the adjusting screw 101 is located in the inner cavity of the rotating groove. A screwdriver groove is provided on the top wall of the adjusting screw 101. The direction in which the pushing block 102 is driven to rise by rotating the adjusting screw 101 is consistent with the locking direction of the screw body 100, and the top wall of the pushing block 102 is inclined.

[0023] The inner cavity of the screw body 100 is provided with anti-rust oil, and the outer wall of the screw body 100 is evenly provided with drainage ports. The lower side of the outer wall of the pushing block 102 is fixedly connected with a liquid pushing ring 105, which is convenient for pushing the anti-rust oil. The liquid pushing ring 105 is located on the inner wall of the screw body 100.

[0024] In the present embodiment: the anti-rust oil is pushed by moving the pushing block 102, so that the anti-rust oil is discharged from the drain port, and the anti-rust oil fills the gap, which can prevent the screw body 100 from contacting with the air, and can make it easy for the device to inject the anti-rust oil into the gap, avoiding the screw body 100 from contacting with the air, which is beneficial to the anti-rust performance of the screw body 100.

[0025] Slide rods 106 are fixedly connected to the left and right sides of the upper and lower side walls of the inner cavity of the screw body 100 , and the slide rods 106 facilitate the movement of the pushing block 102 for limiting guidance. The pushing block 102 is located on the outer wall of the slide rod 106 .

[0026] In this embodiment, the sliding rod 106 is provided to limit the movement of the pushing block 102, thereby preventing the pushing block 102 from deflecting, and facilitating the limiting and guiding of the movement of the pushing block 102, so as to facilitate the deformation of the pushing sealing ring 104.

[0027] The outer wall of the screw body 100 is evenly provided with grooves, and the inner cavities of the grooves are rotatably connected to the limit strips 107. The limit strips 107 are conveniently used to press against the inner wall of the hole groove on the guardrail for limiting and fixing to prevent loosening and deflection. The inner cavities of the grooves are fixedly connected with springs 108, and the springs 108 are convenient to push the limit strips 107 to rotate against the inner wall of the hole groove for limiting. The other end of the spring 108 is connected to the outer wall of the limit strip 107.

[0028] In this embodiment: the limit bar 107 is pushed to rotate by the spring 108 so that the limit bar 107 abuts against the inner wall of the guardrail hole groove, which can prevent the screw body 100 from loosening and deviating, and is conducive to locking the screw body 100.

[0029] A quick release ring 109 is rotatably connected to the outer wall of the screw body 100 , and an adjustment groove is formed on the top wall of the quick release ring 109 .

[0030] In this embodiment: by rotating the quick-release ring 109, the limit bar 107 is pushed to rotate, so that the limit bar 107 rotates back to the inner cavity of the groove, the push of the limit bar 107 is released, and the screw body 100 is rotated in reverse for disassembly, which is conducive to improving the disassembly rate.
