DETAILED DESCRIPTION

[0023] like Figure 1-Figure 5 As shown, the utility model provides a technical solution: a rust-proof anchor bolt, comprising an embedded part 1 and a bolt body 2, the bolt body 2 is fixed on the top of the embedded part 1, and a protection mechanism 3 for protecting the bolt body 2 is provided on the embedded part 1.

[0024] Specifically, the protection mechanism 3 includes a slider 31, a protection cover 32, a connecting spring 36, a transmission spring 34, a block 33, a slot 35 and an extrusion rod 37; the slider 31 is slidably installed on the inner side of the embedded part 1, and a connecting spring 36 is fixed on the top of the slider 31, and the top of the connecting spring 36 is fixed on the inner side of the embedded part 1. By setting the connecting spring 36, the slider 31 can be reset, and a protection cover 32 is fixed on the top of the slider 31. By setting the protection cover 32, the bolt body 2 can be shielded and protected to prevent some liquid from falling on the bolt body 2, which may easily cause the bolt body 2 to rust. A block 33 is slidably installed on the inner side of the slider 31, and a transmission spring 34 is fixed on the side wall of the block 33. The side of the transmission spring 34 away from the block 33 is fixed on the inner side of the slider 31, and the transmission spring 34 can be set to reset the block 33. The block 33 is provided with two groups, and the two groups of block 33 are symmetrically arranged with the center line of the slider 31 in the vertical direction as the axis of symmetry. The outer wall of the embedded part 1 is provided with a card slot 35. When the device needs to be used, the slider 31 can be moved downward to stretch the connecting spring 36. When the slider 31 moves downward to the block 33 and fits with the card slot 35, the transmission spring 34 is in a compressed state, and the diameter of the block 33 is the same as the diameter of the card slot 35. Through the transmission spring 34, the block 33 can be extended into the card slot 35. Because the elastic coefficient of the transmission spring 34 is larger than the elastic coefficient of the connecting spring 36, the slider 31 is fixed, and then the bolt body 2 is exposed, and the device is used. An extrusion rod 37 is fixed at the bottom of the slider 31. When the slider 31 moves downward, the extrusion rod 37 can be driven to move downward. A stabilizing mechanism 4 is provided on the embedded part 1.

[0025] Specifically, the stabilizing mechanism 4 includes an articulated block 41, a stabilizing bracket 42, a push block 43, a push rod 44, a connecting block 45, a movable rod 46, a reset spring 47, a slide groove 48 and a moving block 49. The outer wall of the embedded part 1 is fixed with an articulated block 41, and a stabilizing bracket 42 is hinged on the articulated block 41. The stabilizing bracket 42 is provided with two groups, and the two groups of stabilizing brackets 42 are symmetrically arranged with the center line of the embedded part 1 in the vertical direction as the symmetry axis. By arranging the stabilizing bracket 42, the device can be stably supported to prevent tilting and collapse. The embedded part 1 is provided with a through hole 5, and a push rod 44 is slidably installed on the inner wall of the through hole 5. The bottom of the push rod 44 is fixed with a connecting block 45, and the top of the connecting block 45 is fixed with a reset spring 47. The top of the reset spring 47 is fixed on the inner side of the embedded part 1. By arranging the reset spring 47, the push rod 44 can be reset. The inner wall of the embedded part 1 is slidably installed with a push block 43, and the stabilizing bracket 42 is close to the embedded part 1. A slide groove 48 is provided on one side of the embedded part 1, and a moving block 49 is slidably installed on the inner wall of the slide groove 48. The side wall of the push block 43 is hinged to the side wall of the moving block 49, and the side wall of the connecting block 45 is hinged with a movable rod 46. The end of the movable rod 46 away from the connecting block 45 is hinged on the push block 43. The diameter of the through hole 5 matches the diameter of the extrusion rod 37. When the slider 31 drives the extrusion rod 37 to extend into the through hole 5, the extrusion rod 37 will squeeze the push rod 44, so that the push rod 44 drives the connecting block 45 to move downward, so that the connecting block 45 squeezes the movable rod 46, so that the movable rod 46 squeezes the two groups of push blocks 43 away from each other, so that the push block 43 squeezes the moving block 49 to move in the slide groove 48, so that the two groups of stable brackets 42 can be unfolded. When the slider 31 is fixed, the stable bracket 42 can be unfolded and fixed. The stable bracket 42 can make the device stable and prevent the device from being offset and tipping when the nut is screwed on the bolt body 2.

[0026] Working principle: The bolt body 2 is shielded by the protective cover 32, so as to protect the bolt body 2. When the bolt body 2 needs to be used, the slider 31 can be moved downward to stretch the connecting spring 36. When the slider 31 moves downward to the block 33 and fits the card slot 35, the transmission spring 34 is in a compressed state, and the block 33 can be extended into the card slot 35 through the transmission spring 34. Since the elastic coefficient of the transmission spring 34 is greater than the elastic coefficient of the connecting spring 36, the slider 31 is fixed, so that the bolt body 2 is exposed and the device is used. When the bolt body 2 is not used, the protective cover 32 can be directly pulled upward. When the protective cover 32 is pulled, the arc surface of the block 33 will contact and squeeze the inner wall of the card slot 35. When the block 33 is subjected to the extrusion force, the block 33 will move into the card slot 35, so that the effect of the protective cover 32 can be released. Through the cooperation of the connecting spring 36, the protective cover 32 can shield and protect the bolt body 2.

[0027] When the slider 31 drives the extrusion rod 37 to extend into the through hole 5, the extrusion rod 37 will squeeze the push rod 44, so that the push rod 44 drives the connecting block 45 to move downward, and the connecting block 45 squeezes the movable rod 46, so that the movable rod 46 squeezes the two groups of push blocks 43 away from each other, and the push block 43 squeezes the movable block 49 to move in the slide groove 48, so that the two groups of stable brackets 42 can be unfolded.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
