Countable lead seal
The invention discloses a countable lead seal. The lead seal consists of a number disc, a sealing cover and a casing, wherein the number disc is arranged in a circular groove of the casing; a rotating hole sleeves a rotating shaft; the sealing cover is arranged on the casing in a buckling manner, and the sealing cover and the casing are mutually fixed; a positioning hole sleeves the rotating shaft; a number hole is aligned with one of number icons on the number disc; the inner side part of a limit block is arranged at an outer side part in a space defined by every two adjacent long blocking columns at one end of the number disc; an insertion buckle can be inserted in an insertion hole, and the inner side part of the insertion buckle is arranged at the outer side part in a space defined by every two adjacent long blocking columns at the other end of the number disc. The lead seal disclosed by the invention can be conveniently sealed and opened during use, and can be reused, and the using times can be recorded after the lead seal is used every time, so that the improvement of economy is facilitated, and the improvement of the management level is also facilitated.
