Embodiment Construction
[0028] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0029] figure 1, figure 2 with image 3 Shown is the structure of Embodiment 1 of the present invention, Fig. 1, Figure 4 with Figure 5 Shown is the structure of Embodiment 2 of the present invention. As can be seen from the figure, the same technical solutions of the two embodiments are:
[0030] The anti-corrosion protection device for bolts of the present invention has a sealing anti-off base with a protective cover, which includes an upper protective cover 1 , a lower protective cover 2 and a positioning main board 3 . The upper protective cover 1 and the lower protective cover 2 are cylindrical, and the positioning main board 3 is located between the upper protective cover 1 and the lower protective cover 2 . An upwardly protruding cylindrical boss 4 is provided at the center of the positioning main board 3, and the center of the boss 4 is a t...

The invention discloses a seal anti-disengaging base provided with protection covers for a bolt anti-corrosion protection device. The upper protection cover, the lower protection cover and a positioning main board are included. The positioning main board is located between the interior of the upper protection cover and the interior of the lower protection cover. A cylindrical boss upwards protruding is arranged at the center of the positioning main board. The center of the boss is provided with a nut positioning hole. On the positioning main board, the outer edge of the boss is provided with aseal protruding strip, and a seal groove is formed below the positioning main board. The seal anti-disengaging base is good in corrosion preventing performance, disengaging preventing performance, seal performance and fastening performance, the situation that outside air and water enter the bolt anti-corrosion protection device and corrode bolt facilities can be more effectively and reliably prevented, the bolt anti-corrosion protection device can be tightly and firmly combined with nuts and bolts, and disengaging under the action of external force is avoided. The base can be repeatedly utilized many times, and the service life is long; and bolt detachment can be convenient, cost is reduced, the overhauling speed is increased, and meanwhile structure safety is guaranteed.
Description
technical field [0001] The invention belongs to the technical field of bolt protection components, and in particular relates to a sealing anti-off base with a protective cover of a bolt anticorrosion protection device. Background technique [0002] As the basic element of connection and fixation, bolts are likely to affect the stability of the entire connection structure once they are corroded, and may even cause dangers such as fracture and collapse; in the existing bolt stability inspection, even routine inspections are often performed to ensure that corroded bolts are timely Replacement, but because the bolts are difficult to unscrew after corrosion, the replacement is relatively inconvenient, and it will also affect the inconvenient maintenance and disassembly of related parts fixed by bolts, which consumes a lot of manpower and material resources, with high cost and low efficiency. [0003] Where foundation bolts are used in existing railway systems, there are not many ...
