Embodiment Construction
[0024] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0025] refer to figure 1 , the preferred embodiment of the present invention has a spiral lock cylinder structure with lock pieces and a spiral key, the spiral lock cylinder structure includes a lock cylinder shell 1, a lock cylinder body 2, and a plurality of cards spaced apart from each other System group 3. It should be noted that in this embodiment, the number of the locking groups 3 is three, and they are located in different positions, but it is not limited thereto, and can be increased or decreased according to actual needs.
[0026] refer to figure 2 and cooperate figure 1 As shown, the lock cylinder housing 1 includes an inner ring surface 11 defining an inner space 111, a plurality of position-limiting holes 12 that are respectively separated and communicated with the inner space 111, and two spaced apart protruding from the inner space....

The invention discloses a spiral type lock cylinder structure with a locking plate and a spiral type key. The spiral type lock cylinder structure comprises a lock cylinder shell comprising a limiting hole, a lock cylinder body comprising a lock channel which is communicated with the outside and is in a spiral shape, and a clamping set. The clamping set is provided with the locking plate and an elastic member. The locking plate is provided with a body, a protruded part and a linkage part. The body is provided with a cross-span space and can be crossly arranged on the lock cylinder body. The protruded part protrudes and extends from the body to the position where is far away from the cross-span space. The linkage part protrudes and extends to the cross-span space from the body and extends into the lock channel. One end of the elastic member abuts against the body, and when no external force is exerted or the external force is vanished, the protruded part of the locking plate is kept to be in the state that the protruded part extends into the limiting hole. The spiral type key comprises a key handle and a key body which is connected with the key handle and in a spiral shape. According to the design of the spiral type key and the spiral type lock cylinder structure, the safety can be improved.
Description
technical field [0001] The present invention relates to a spiral lock cylinder structure with lock pieces and a spiral key, in particular to a spiral lock cylinder structure with lock pieces and a spiral key for a safer anti-theft lockset. Background technique [0002] Anti-theft locks currently on the market are more common with mechanical pin tumbler locks and wafer tumbler locks, such as the tumbler lock disclosed in US Patent No. US5964111A and the wafer lock disclosed in US Patent No. US6978647B2. Most of the lock cylinder structures of the existing pin locks are for a key to be inserted into the lockway of a straight groove and corresponding to the lock cylinder body radially assembled with pins. If a straight rod-shaped unlocking tool is used to insert into the lockway of the lock cylinder body, The marbles can be touched, and the purpose of unlocking can be easily achieved. Similarly, the lock core structure of the existing chip lock is also a lock core body in a st...
