Abstract

The invention discloses a detachable theft-proof chalk box, comprising a fixed frame installed on a platform, a storage box which is positioned on the top of the fixed frame and is used for storing chalks, and an access box positioned under the storage box, wherein the access box and the fixed frame are connected with each other in a detachable way; the fixed frame comprises a base, a thin rod positioned on the base, and a thick rod which is positioned above the thin rod and forms an integral structure together with the thin rod; an inserting hole is formed in the middle of the front side faceof the thick rod; a receiving plate is inserted in the inserting hole. The device is ingenious in structure; the access box and the storage box are arranged in a detachable way, so that the access box can be disassembled when the chalk box is not in use, and the chalk waste caused by people without fixed duties can be further avoided; due to arrangement of devices such as a torsion plate and a triangular sliding seat in the access box and the storage box, malicious operations are avoided after the chalk box is disassembled, and the theft-proof property of the device is further improved; therefore, the detachable theft-proof chalk box is suitable for being popularized in various schools, and the teaching cost is lowered.
