Embodiment Construction

[0024] In order to better understand the shape, structure and characteristics of the present invention, preferred embodiments will be listed below and described in detail with reference to the accompanying drawings.

[0025] Such as figure 1 As shown, the present invention provides a basic bolt anti-corrosion protection device, which includes a cylindrical sleeve 1 and a cylindrical sleeve rod 2 integrally connected, the inner diameter of the sleeve 1 is slightly larger than the diameter of the nut or is the same as the diameter of the nut Equal, one end of the sleeve body 1 has an opening for the screw rod and nut of the foundation bolt to extend in, and the other end is connected to one end of the sleeve rod 2, the inner diameter of the sleeve rod 2 is smaller than the inner diameter of the sleeve body 1, but smaller than the diameter of the screw rod Slightly larger or equal to the diameter of the screw rod, so that the screw rod can be sleeved in the sleeve rod 2 . The ot...

Abstract

The invention provides a bay bolt anti-corrosion protection device which comprises a sleeve. An opening is formed in one end of the sleeve, a screw and a nut of a bay bolt extend into the opening, the other end of the sleeve is connected with one end of a sleeve rod, the inner diameter of the sleeve rod is smaller than the inner diameter of the sleeve, and therefore the screw is sleeved with the sleeve rod, and the other end of the sleeve rod is closed. By means of the bay bolt anti-corrosion protection device, the bay bolt can be isolated from a corrosive medium under the effect of a protection cover, and the bolt is effectively prevented from being corroded. In this way, the bolt can be conveniently dismounted, cost is reduced, the overhauling speed is increased, and the structure safety is guaranteed.

Description

technical field [0001] The invention relates to a protective cover, in particular to a foundation bolt anticorrosion protection device. Background technique [0002] Bolts are widely used in many occasions, but there are few protection methods for the bolts, and the existing bolts are generally directly exposed to the air. Due to the moisture and oxygen in the air, the bolts are prone to corrosion of the zinc layer in this case, thereby oxidizing and rusting. Especially for bolts located outdoors and in coastal areas, in addition to the air, there may be wind, frost, rain, snow, sunlight, and ocean erosion, especially ocean erosion, which is more likely to cause corrosion between the metals of the bolts and nuts, and damage the power supply equipment. cause harm. [0003] As the basic element of connection and fixation, bolts are likely to affect the stability of the structure once they are corroded, and even cause dangers such as fracture and collapse. Even if routine in...
