The utility model is a lock device that can be set repeatedly. It is another preferred specific embodiment added under the framework of China Taiwan Patent Application No. 97133519. The content of the specification of the utility model is based on the specification For the extension of the structure, the part mentioned in the description will not be described in detail, but only the newly added part of the utility model will be described here.

As shown in Figures 1 and 2, the lock housing 11' is similar to an ordinary cylinder, which defines an axis 9' and forms an axial hole 120' in the center, and the lock housing 11' has a first end 111', The second end 112' and the cylindrical wall 113' forming the inner surface 114', the cylindrical wall 113' forms the accommodating chamber 119', the first end 111' has a guide groove 109', the second end 112' It has an engaging portion 110'.

A pushing element 41' is roughly shaped as a rectangular plate to be installed in the accommodating chamber 119' of the lock housing 11'. The front side of the pushing element 41' extends a cantilever 415' along the circumference of the lock core 21'. The end of the pushing element 41' has a stop portion 43', and the pushing element 41' can be displaced in the accommodation chamber 119' under the bias of the spring 42'.

The lock core group 2' can be accommodated in the axial hole 120' of the lock housing 11', which includes: a lock core 21', a plurality of springs 24', a plurality of first laterally slidable elements 23', Two balls 25', a plurality of springs 26', a spring 27', a third laterally slidable element 28' and a setting device 3'.

The lock core 21' has a first part 211' and a third part 213', and there is a recess 228' between the first part 211' and the third part 213', which can accommodate the device. Fixing device 3', the lock core 21' can be accommodated in the axial hole 120' of the lock housing 11'; the first part 211' of the lock core 21' has a groove 210', a flange 209' and A key support hole 208' (only shown in Figure 1), the third part 213' of the lock core 21' forms an outer ring groove 291' on the circumference, and has a A hole 292', at least one transmission part 290' is formed around the hole 292'.

The setting device 3' is accommodated in the alcove 228' of the lock core 21' and can move in a direction substantially perpendicular to the axis 9' of the lock housing 11'; the setting device 3' has a second lateral direction The slidable element 34', the second transversely slidable element 34' can pass through a through hole 319', and make the second transversely slidable element 34' a through hole extending into the pushing element 41' (the The shape of the through hole 414' can move between the approximately circular or approximately elliptical) 414' and the through hole 414' that does not extend into the pushing element 41'.

A transmission plate 71' has a first drive part 711' and a second drive part 712', the first drive part 711' can extend into the hole 292' of the lock core 21', and accept the drive of the lock core 21' Pushing the part 290', a ring 72' can be sleeved in the hole 292' of the lock core 21' to limit the axial disengagement of the transmission plate 71'.

A fixing element 73' has a central hole 731' that can be sleeved on the lock housing 11', and the fixing element 73' has a convex portion 732' and an engaging portion 733', when the engaging portion 733 of the fixing element 73' When engaging the engaging portion 110' of the lock housing 11', the convex portion 732' of the fixing element 73' can align with the stop portion 43' of the pushing element 41'.

A transmission sleeve 81', which can be loosely installed on the third part 213' of the lock core 21', the transmission sleeve 81' has a hole 811', a resisting portion 812', an arc-shaped hole 813' and an inner ring groove 815' (the inner ring groove 815' is shown in Figs. 5 and 8 ), and the arc-shaped hole 813' of the drive sleeve 81' can fit over the convex portion 732' of the fixing element 73'. The outer ring groove 291' of the lock core 21' is opposite to the inner ring groove 815' of the drive sleeve 81', forming a space for a buckle ring 74' to be installed to limit the axial separation of the drive sleeve 81'. The transmission sleeve 81 ′ can rotate relative to the lock core 21 ′ and the lock housing 11 ′, and at least one toggle portion 814 ′ is formed around the hole 811 ′ of the transmission sleeve 81 ′.

As shown in Figures 3 to 5, this state is that the lock device 1' is not inserted into the first mating key 61', and it is in a locked state, at this time, the second laterally slidable element 34' can extend into the push element 41' through hole 414' (as shown in Figure 5), the resisting portion 812' of the transmission sleeve 81' is located in the stopper portion 43' of the pushing element 41', so the axial direction of the pushing element 41' can be limited. Move; at this time, use a tool to push the cantilever 415' of the push element 41' (as shown by the arrow), and the movement of the push element 41' will be restricted. 'Push against the cantilever 415' of the pushing element 41'.

And it will not affect the unlocking of the first matching key 61'.

As shown in Figures 6 to 8, when the matching key is to be replaced, the first matching key 61' is inserted into the lock core 21' so that the first matching key 61' is partially accommodated in the key support hole 208' (as shown in Figure 1) , turn the first matching key 61' to make the lock core 21' rotate an angle from the initial position, the transmission part 290' of the lock core 21' will drive the first drive part 711' of the transmission plate 71', and then the transmission plate 71' rotates an angle, and then the second driving part 712' pushes the toggle part 814' of the transmission sleeve 81', and at this time, the resisting part 812' of the transmission sleeve 81' is aligned with the stopper part of the pushing element 41' The position of 43' is rotated to the position that is not aligned with the stopper 43' of the pushing element 41' (as shown in Figure 6). Due to the relationship of the rotation angle, the first matching key 61' can be rotated in the opposite direction by an angle to return to the original position. That is, it is in the unlocked state. At this time, the resisting part 812' of the transmission sleeve 81' is located at a position that is not aligned with the stop part 43' of the pushing element 41' (as shown in Figure 6), and the groove 210' of the lock core 21' is aligned with the The cantilever 415' of the pushing element 41' is axially aligned, and the cantilever 415' can be pushed to move the pushing element 41'. At this time, the setting can be performed and the second matching key can be replaced, and the matching key can be replaced in detail. The structure and method are described in detail in China Taiwan Patent Application No. 97133519.

The above is the specific embodiment of the utility model used in the auxiliary lock device. If it is applied to the horn lock or tubular lock device, the end of the lock core 21' of the lock device 1' should be changed as shown in Figure 9. The lock The end of the third part 213' of the core 21' has a hole 292", and at least one transmission part 290" is formed around the hole 292".
