DETAILED DESCRIPTION

Implementations of the present disclosure will now be described, by way of embodiments only, with reference to the drawings. It should be understood that the specific embodiments described here are only used to explain but not to limit the present application. Based on the embodiments in the present application, all other embodiments obtained by one ordinary skill in the art without creative labor is within the scope of the present application.

The invention is further explained below in combination with the attached drawings and the embodiment.

Referring to FIG. 1,-7, FIG. 1 is a schematic diagram of a first embodiment of the lock core structure provided by the invention; FIG. 2 is a schematic diagram of the twisted hand shown in FIG. 1; FIG. 3 is a side view of the face cover shown in FIG. 1; FIG. 4 is a schematic diagram of the surface cover and the rotating member shown in FIG. 1; FIG. 5 is a schematic diagram of the first working state structure of the overall device; FIG. 6 is a schematic diagram of the second working state structure of the apparatus shown in FIG. 5; FIG. 7 is a three-dimensional structural diagram of the overall working state of the device.

A twist on the hand to replace the lock core structure, which comprise:

• • Face cover 1 and wrench 8, the face cover 1 is provided with a rotating member 2;
  • the lock core structure 3 is provided on one side of the rotating member 2 connected with a twist hand 4 and the hand screw 5 is provided between the rotating member 2 and the twist hand 4.

There is the screw hole 6 between the rotating member 2 and the hand screw 5.

The surface of the face cover 1 is provided with a password controller 7.

Referring to FIG. 5 and FIG. 6, obvious, the unlocked state means that the twist hand 4 can be unscrewed clockwise to reveal the hole position of hand screw 5, the hand screw 5 will vertical blocked by the door handle when it is not unlocked.

This invention can replace the lock core assembly position is outside the front panel of the door lock, Covered by a twisted hand or handle, Twist the hand or handle through a locking screw is confined to the front panel, Will not be removed to replace the lock core, Only after entering the correct password, When the hand or handle is rotate, In turning the twist hand or handle to a specific position, Expose the locking screw holes, The user can remove the twist hand or handle by releasing the locking screw, To replace the external lock core, When the door is locked, When the hand or the hand is not turning, A protective ring on the door lock panel will cover this screw hole, The person outside the door is unable to loosen the locking screw and remove the twisting hand or handle.

The working principle of replacing the lock core structure is as follows:

When unlocking the lock, use the screw hand screw 5, take out the twist hand 4, and then take out the lock core structure 3 for replacement.

Rewing twist hand 4 requires screw the tip of hand screw 5 into screw hole 6.

Compared with the related techniques, a mechanical lock password setting and reset structure provided by the present invention have the following beneficial effects:

The disclosure provides a twisted hand replacement lock core structure, Set hand screw 5 between rotating member 2, lock core structure 3 and twist hand 4, Hand screw 5 can lock the rotating member 2 and twist hand 4, When the lock core structure 3 is damaged or needs to be replaced, Lock core structure 3 can be removed and replaced by wrench 8, This can realize the disassembly and replacement of the lock core from the handle part, And only if entering the correct password, After turning the handle to reach the specified position, Only when the lock core can be replaced, If the door lock is closed, Incorrect password entry, The screw holes in the hand will be covered, Will not be exposed, While ensuring the replacement of the lock core, it increases the effect of anti-theft.

The above is only the embodiment of the disclosure, not therefore limit the scope of the patent of the disclosure, all using the contents of the specification and the drawings of the equivalent structure or equivalent process transformation, or directly or indirectly in other related technical fields, the same is included in the scope of patent protection of the disclosure.
