The invention discloses a filter locking bolt. The locking bolt comprises a tank, an upper cover, more than three pairs of T-shaped bolts connected through threads, as well as nuts provided with handles, wherein upper bolt slots used for embedding screw parts of the T-shaped bolts are uniformly formed in the outer edge of the upper cover, lower bolt slots corresponding to the upper bolt slots are formed in the outer edge of a tank opening of the tank, the number of the upper bolt slots is equal to that of the T-shaped bolts, and cross bar parts of the T-shaped bolts are rotationally connected with the lower bolt slots. With adoption of the filter locking bolt, when a security filter is required to be sealed, the screw parts of the T-shaped bolts are clamped into the upper bolt slots, then the nuts are rotated, and the upper cover can be tightly buckled on the tank; when the upper cover is required to be opened, the upper cover can be easily opened in reverse steps. Therefore, the replacement time of a filter element of the security filter can be greatly saved, and the labor intensity can be greatly reduced.
