The invention discloses a hidden core chain lock body structure which comprises a lock body, a chain and an L-shaped key. A lock core chamber and a P-shaped channel are formed in the lock body, the P-shaped channel is communicated with the lock core chamber and used for unlocking, a lock core is fixed in the lock core chamber, a key hole of the lock core faces the P-shaped channel, a bulkhead is arranged on an lock core inlet of the lock core chamber, an opening corresponding to a lock tongue on the lock core is formed in the inner surface of the bulkhead, and the lock body is made of a cylindrical solid round steel or a hexagonal solid steel. The lock core is fixedly and deeply hidden in the lock core chamber of the lock body machined by the solid round steel, the L-shaped key is inserted into the hidden lock hole from a key slot of a P-shaped channel opening, so that the lock body structure can be used, and the lock hole has hidden, prying resistant and cutting resistant effects. Lock core balls are reinforced solid balls made by solid copper, and the twisting resistance of the lock core is further improved.
