[0027] Further, the bottom of the clamping sleeve 1 is bonded with a sealing ring 10, which can reduce the entry of rainwater or moisture into the bolt surface.
[0028] Further, the threaded sleeve 3 is integrally connected with a sliding sleeve 7 on both sides of the surface of the clamping sleeve 1, the sliding sleeve 7 is internally slidably connected with a sliding rod 6, one end of the sliding rod 6 is fixedly connected with the surface of the connecting plate 8 through a screw, which facilitates the lead screw 4 to drive the clamping plate 9 to be more stable and fixedly clamp the bolt surface.
[0029] Further, the telescopic link 13 is externally sleeved with a clamping spring 11, and the surface of the clamping plate 9 is paved with a non-slip rubber pad, which facilitates the clamping plate 9 to clamp the bolt surface of different shapes, thereby improving the applicability of the entire protection cover 2.
[0030] Further, the top edge of the clamping sleeve 1 is provided with a threaded groove 12, and the bottom of the protection cover 2 is integrally connected with a threaded ring 14, the threaded ring 14 is threadedly fixedly connected with the threaded groove 12, which facilitates the installation and disassembly of the protection cover 2 and the clamping sleeve 1.
[0031] Further, the bottom surface of the fixing sleeve 16 is symmetrically provided with a communication groove 18, the inner cavity side wall of the communication groove 18 is provided with a limiting groove 19, the surface of the fixing block 20 is symmetrically provided with a limiting block 21, the limiting block 21 is fixedly connected with the limiting groove 19 through the communication groove 18, the inner cavity top of the fixing sleeve 16 is bonded with a magnet piece 17, the top of the fixing block 20 is fixedly connected with the magnet piece 17 through magnetic attraction, which is convenient for dismounting and mounting the protective sponge 15, thereby facilitating subsequent maintenance.
[0032] Further, the protective sponge 15 is attached to the surface of the bolt, and the protective sponge 15 has adsorbed protective oil therein, so that the rusting of the bolt to be protected can be reduced.
[0033] Working principle: when installing the bolt protection cover, first, the clamping sleeve 1 is sleeved on the bolt, so that the bolt passes through the center of the clamping sleeve 1. At this time, the rotating wheel 5 at one end of the screw rod 4 is rotated, and the screw rod 4 rotates in the threaded sleeve 3. Since the screw rod 4 is threadedly connected with the threaded sleeve 3, and the other end of the screw rod 4 is mounted on the connecting plate 8 through a bearing, when the screw rod 4 rotates, the connecting plate 8 moves inside the clamping sleeve 1. At the same time, the sliding rods 6 in the sliding sleeves 7 on both sides of the threaded sleeve 3 are fixedly connected with the connecting plate 8, so as to ensure the stable movement of the connecting plate 8.
[0034] With the movement of the connecting plate 8, the clamping plate 9 mounted on the surface thereof also moves. The telescopic rods 13 on the back of the clamping plate 9 and the clamping springs 11 outside the sleeve can automatically adjust the position and clamping force of the clamping plate 9 according to the shape of the bolt, and the surface anti-skid rubber pad increases the friction force, so as to ensure firm clamping and stably fix the clamping sleeve 1 on the bolt.
[0035] Then, the threaded ring 14 at the bottom of the protection cover 2 is aligned with the threaded groove 12 at the top of the clamping sleeve 1, the two are threadedly connected by rotating the protection cover 2, and the installation is completed. At this time, the protective sponge 15 in the fixing sleeve 16 in the inner cavity top of the protection cover 2 is attached to the surface of the bolt. The protective oil adsorbed in the protective sponge 15 can form a protective film on the surface of the bolt, so as to prevent the bolt from rusting.
[0036] When it is necessary to dismount the protection cover for bolt inspection, maintenance or replacement, the protection cover 2 is reversely rotated to separate it from the clamping sleeve 1. Then, the rotating wheel 5 is rotated to loosen the clamping of the clamping plate 9 on the bolt, and the entire protection cover can be removed. If it is necessary to replace or maintain the protective sponge 15 alone, the limiting block 21 on the fixing block 20 is separated from the clamping of the communication groove 18 and the limiting groove 19 of the fixing sleeve 16, and the fixing block 20 and the connected mounting plate 22 and protective sponge 15 are easily removed, which is simple and convenient to operate.
[0037] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
