Description

Technical Field

[0001] This utility model relates to the technical field of corrosion-resistant anchor screws, specifically a corrosion-resistant anchor screw. Background Technology

[0002] Anchor bolts are used to connect structural and non-structural components to concrete. The connection is achieved by assembling different parts, such as anchor bolts, steel plates, and stiffening ribs. Existing anchor bolts do not have anti-corrosion properties and will corrode after being exposed to rainwater, resulting in a short lifespan. Therefore, a corrosion-resistant anchor bolt is needed.

[0003] Chinese patent CN222577110U discloses a corrosion-resistant anchor bolt, including a base plate, a screw body fixedly connected to the top of the base plate, a nut threadedly connected to the outer wall of the screw body, a rectangular groove at the bottom of the base plate, and rectangular through holes at both ends of the base plate, which communicate with the rectangular groove. This patent uses a folding component, a limiting component, and an engaging component. By adjusting the limiting component, the limiting component disengages from the engaging component. At this time, rotating the engaging component increases the stability of the anchor bolt. When laying the cement base, the fixing hook of the anchor bolt's base plate needs to be embedded in the cement. After the cement solidifies, the device to be fixed is passed through the screw body, and then the nut is threadedly connected to the screw body to fix the device. By fitting the folding component onto the outer wall of the nut, the corrosion of the screw body caused by rainwater is prevented.

[0004] The aforementioned patent has some shortcomings: when using the existing technology for mounting, the base is embedded in the ground through concrete, making it difficult to adjust or move it after it is fixed, which leads to inconvenience in using the base. Utility Model Content

[0005] The purpose of this invention is to provide a corrosion-resistant anchor bolt to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a corrosion-resistant anchor bolt, including a base, a threaded post fixedly connected to the top of the base, a first nut fixedly sleeved on the outside of the threaded post, a second nut fixedly sleeved on the outside of the threaded post, a sleeve movably sleeved on the top of the second nut, a mounting plate fixedly connected to the top of the sleeve, a fixing screw sleeved on the inside of the mounting plate, an anti-slip groove provided at the bottom of the base, a protective sleeve fixedly sleeved on the outside of the base, and a protective mechanism provided at the top of the base.

[0007] Preferably, the sleeve is movably fitted onto the top of the threaded post, and the sleeve is located directly below the mounting plate.

[0008] Preferably, there are several anti-slip grooves, which are evenly distributed on the bottom of the base.

[0009] Preferably, the protective sleeve is made of nylon material and is compatible with the base.

[0010] Preferably, the protective mechanism includes a bellows, which is movably sleeved on the outside of the threaded post, a spring is fixedly sleeved inside the bellows, and a protective cover is fixedly sleeved on the top of the bellows.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This corrosion-resistant anchor bolt, by setting a sleeve, when the anchor height needs to be adjusted, fix the first nut and rotate the second nut, so that the first nut and the second nut can rotate in opposite directions, thereby allowing the second nut to drive the sleeve to move up and down outside the threaded column, that is, to drive the mounting plate to move up and down, thereby achieving the effect of adjusting the height of the mounting plate, and thus achieving the effect of adjusting the height of the supported equipment, thereby improving the convenience of using the anchor bolt;

[0012] In addition, the corrosion-resistant anchor bolt also features a sleeve. When the anchor height needs to be adjusted, the first nut is fixed and the second nut is rotated, allowing the first and second nuts to rotate in opposite directions. This causes the second nut to move the sleeve up and down outside the threaded post, which in turn moves the mounting plate up and down, thus achieving the effect of adjusting the height of the mounting plate and the supporting equipment. This improves the convenience of using the anchor bolt. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please see Figure 1-3 An embodiment of this utility model provides a corrosion-resistant anchor bolt, comprising a base 1, a threaded post 2 fixedly connected to the top of the base 1, a first nut 3 fixedly sleeved on the outside of the threaded post 2, a second nut 4 threadedly sleeved on the outside of the threaded post 2, a sleeve 5 movably sleeved on the top of the second nut 4, a mounting plate 6 fixedly connected to the top of the sleeve 5, a fixing screw 7 threadedly sleeved on the inside of the mounting plate 6, an anti-slip groove 8 provided at the bottom of the base 1, a protective sleeve 9 fixedly sleeved on the outside of the base 1, and a protective mechanism 10 provided at the top of the base 1.

[0023] The sleeve 5 is movably fitted onto the top of the threaded post 2, and the sleeve 5 is located directly below the mounting plate 6. By setting the sleeve 5, when the height of the foot needs to be adjusted, the first nut 3 is fixed and the second nut 4 is rotated, so that the first nut 3 and the second nut 4 can rotate in opposite directions. This allows the second nut 4 to drive the sleeve 5 to move up and down outside the threaded post 2, that is, to drive the mounting plate 6 to move up and down, thereby achieving the height adjustment effect of the mounting plate 6, and thus achieving the height adjustment effect of the supporting equipment, thereby improving the convenience of foot use.

[0024] There are several anti-slip grooves 8, which are evenly distributed on the bottom of the base 1. By setting the anti-slip grooves 8, when the base is in use, the anti-slip grooves 8 greatly improve the friction between the ground and the base 1, that is, improve the stability of the base 1 and avoid the problem of sliding when the base 1 shakes.

[0025] The protective sleeve 9 is made of nylon material and is compatible with the base 1. By setting the protective sleeve 9, the protective sleeve 9 can seal the outside of the base 1 when it is in use, making it difficult for the base 1 to come into contact with external water and air, thereby avoiding the problem of corrosion when the base 1 comes into contact with the outside air.

[0026] The protective mechanism 10 includes a bellows 101, which is movably sleeved on the outside of the threaded post 2. A spring 102 is fixedly sleeved inside the bellows 101, and a protective cover 103 is fixedly sleeved on the top of the bellows 101. By setting the protective mechanism 10, when the anchor is in use, the bellows 101 is sleeved on the outside of the threaded post 2, so that the spring 102 can drive the protective cover 103 to be sleeved on the bottom of the fixing screw 7 through the bellows 101, thereby achieving a sealing effect between the fixing screw 7 and the threaded post 2. This avoids the problem of corrosion when the fixing screw 7 and the threaded post 2 are in a humid environment for a long time, thus greatly improving the corrosion resistance of the anchor screw.

[0027] Working principle: When the height of the foot needs to be adjusted, fix nut 3 and rotate nut 4, so that nut 3 and nut 4 rotate in opposite directions. This causes nut 4 to move sleeve 5 up and down outside the threaded post 2, which in turn moves mounting plate 6 up and down, thus achieving the height adjustment effect of mounting plate 6 and supporting equipment. This improves the convenience of using the foot. When using the foot, the anti-slip groove 8 greatly increases the friction between the ground and the base 1, thereby improving the stability of the base 1 and preventing slippage when the base 1 wobbles. When using the foot, the protective sleeve 9... The base 1 is sealed to the outside, making it difficult for it to come into contact with external water and air during use. This avoids the problem of corrosion when the base 1 comes into contact with the outside air. When using the anchor bolt, the bellows 101 is sleeved on the outside of the threaded post 2, so that the spring 102 can drive the protective cover 103 to be sleeved on the bottom of the fixing screw 7 through the bellows 101. This achieves a sealing effect between the fixing screw 7 and the threaded post 2, thereby avoiding the problem of corrosion when the fixing screw 7 and the threaded post 2 are in a humid environment for a long time. This greatly improves the corrosion resistance of the anchor bolt. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
