Further, described lock core comprises lock core hole, and the top of described lock housing also is provided with the circular arc bayonet socket that matches and be used to lock with lock core hole, the mobile change lock core hole of described lock core and the fore shaft size between the circular arc bayonet socket.

Further, the sidewall of the external end head of described drive link is provided with inside groove, and the end of described key is provided with the slotting tube that matches with described external end head diameter, and this inwall of inserting tube is provided with and the suitable boss of described groove.

Further, described groove circumferentially is set to 2,3 or 4 along described external end head, is provided with 2,3 or 4 boss in the end of described key.

Further, described groove is that 4mm is wide, 2～3mm is dark.

Further, the inner of described external end head is provided with positioning step, also is provided with slide block in the described lock housing, and the top of this slide block is provided with preloading spring, and the lower end pushing tow of slide block is on positioning step.

The utility model prevents that lock has overcome the unlocking tool defective not special-purpose, that opened by general utility tool easily of existing lockset more, and the utility model prevents that lock has improved the safety of the special lockset of down-hole more, has improved the safety of underground work.

The specific embodiment

Extremely shown in Figure 19 as Fig. 1, the utility model is prevented lock more, comprise lock core 1, lock housing 2 and key 3, lock core 1 is inserted in the lock housing 2, lock core 1 comprises lock core hole 17 and axis of rotation 4, axis of rotation 4 is positioned at the inner of the lockhole passage 5 of lock housing 2, its axis of axis of rotation 4 upper edges is provided with screwed hole, the outer end of lockhole passage 5 inwardly is fitted with drive link 6, drive link 6 is the screw-like structure, fixing between the inner of drive link 6 and the axis of rotation 4 by being threaded, so that lock core 1 is fixed in the lock housing 2, the top of lock housing 2 also is provided with the circular arc bayonet socket 16 that matches and be used to lock with lock core hole 17, unblank or the process of locking in, lock core 1 move the fore shaft size that will change between lock core hole 17 and the circular arc bayonet socket 16, it originally is the practicality that utility model is prevented lock more that the changeability of fore shaft size will improve, versatility, make its locking bolt that is applicable to multiple diameter, fore shaft diameter promptly of the present utility model can be automatically and the diameter of locking bolt suitable, make how anti-lock is applicable to multiple use occasion to the utility model.

Be provided with the interface arrangment that matches between the external end head 10 of drive link 6 and the key 3, forms such as the groove that this interface arrangment can be designed to match, boss, in the present embodiment, the sidewall of the external end head 10 of drive link 6 is provided with inside groove 7, and groove 7 is that 4mm is wide, 2～3mm is dark.The end of key 3 is provided with the slotting tube 8 that matches with external end head 10 diameters, and the inwall of inserting tube 8 is provided with the boss 9 suitable with groove 7, inserts external end heads 10 when inserting tube 8, and groove 7 matches with boss 9 after the clamping, and drive link 6 and key 3 upwards interfixed in week.

In order to satisfy different brackets work position, administrative staff's management work, the adaptive form of key 3 and external end head 10 can be designed to various.In the present embodiment, with groove 7 along external end head 10 circumferentially be set to 1,2 or 3, be provided with 2,3 or 4 boss in the slotting tube 8 of key 3 ends.Be external end head shown in Figure 9 10 and key 3 shown in Figure 13 matches, external end head 10 shown in Figure 10 matches with key 3 shown in Figure 14, external end head 10 shown in Figure 11 matches with key 3 shown in Figure 15, and, key 3 shown in Figure 15 can open be furnished with Figure 11, Figure 10, the lock of pattern external end head 10 shown in Figure 9, key 3 shown in Figure 14 can open be furnished with Figure 10, the lock of pattern external end head 10 shown in Figure 9, key 3 shown in Figure 13 can only be opened the lock of being furnished with pattern external end head 10 shown in Figure 9.The structure setting of this classification has made things convenient for the management of underground work, has improved the safety of underground work.

Because during underground work, the vibration of machine etc. can constantly be arranged, in order to prevent in long-time use, what be threaded between drive link 6 and the axis of rotation 4 gets loose, the inner of external end head 10 is provided with positioning step 11, also be provided with slide block 12 and slideway 14 in the lock housing 2, the top of slide block 12 is provided with preloading spring 13, and the lower end pushing tow of slide block 12 is on positioning step 11.Like this after lock core 1 lock installs to the position, slide block 12 is the position of fixed conveyor bar 6, thereby prevented owing to vibrate and cause getting loose between itself and the lock core.

During use, key 3 is inserted in the lockhole of lock housing 2, and firmly press down, so that slide block 12 is depressed, and make it break away from external end head 10, clockwise direction screw key 3, key 3 drives drive link 6 and rotates, and by threaded function, makes lock core 1 move radially along lock housing 2 between drive link 6 and the lock core 1, thereby lock core hole 17 and circular arc bayonet socket 16 are locked mutually, lock with dynamo-electric locking screw shaft with the down-hole that will be positioned between lock core hole 17 and the circular arc bayonet socket 16, make it axially not have operating range, thereby flame-proof switch can not be opened, reach the purpose that the professional just can open with special tool, reach the purpose of safety anti-explosive.
