Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Examples

As shown in fig. 1, 2, 3 and 4, a padlock with a replaceable lock core according to an embodiment of the present utility model includes a lock body 1, a lock core slot 2 is formed on a sidewall of the lock body 1, a lock core body 3 is sleeved in the lock core slot 2, a lock beam through hole 4 penetrating through the lock body 1 is formed on a sidewall of the lock body 1, a lock Liang Mangkong communicated with the lock beam through hole 4 is formed on the other sidewall, a lock beam body 6 is slidingly penetrated between the lock beam through hole 4 and the lock beam blind hole 5, a fixing through hole 7 penetrating through the lock beam through hole 4 and extending into the lock core slot 2 is formed on the top of the lock body 1, a head-free straight screw 8 is slidingly inserted in the fixing through hole 7, a thread slot in threaded connection with the head-free straight screw 8 is formed on the top of the lock core body 3, a transmission slot 9 is formed on one end of the lock core slot 2, a transmission rod 10 is sleeved in the transmission slot 9, one end of the transmission rod 10 is matched and clamped with the driving end of the lock cylinder body 3, a locking groove 11 penetrating through the transmission groove 9 is formed in the lower surface of the lock body 1, the top of the locking groove 11 is communicated with the lock Liang Mangkong 5 through a connecting hole 12, a ball 13 and a sliding block 14 are movably arranged in the locking groove 11, a locking block 15 is sleeved in the connecting hole 12 in a sliding mode, the lower end of the locking block 15 is fixedly connected with the sliding block 14, a first spring 16 and a check ring 17 are sleeved on the outer side of the locking block 15, the upper end of the first spring 16 is fixedly connected with the check ring 17, the check ring 17 is sleeved in the locking groove 11 in a sliding mode, a first clamping groove 18 matched and clamped with the locking block 15 is formed in one side of the lock beam body 6, a second clamping groove 19 is formed in one side of the transmission rod 10, a T-shaped groove 20 is formed in the lock Liang Mangkong 5, a second spring 21 and a T-shaped ejector rod 22 are sleeved in the T-shaped groove 20, and one end of the T-shaped ejector rod 22 abuts against the lock beam body 6; in summary, it can be seen that, because the lock cylinder body 3 is sleeved in the lock cylinder groove 2, the headless straight screw 8 sliding in the fixing through hole 7 is in threaded connection with the thread groove at the upper end of the lock cylinder body 3, so that a part of the headless straight screw 8 is sleeved in the fixing through hole 7 and cannot slide, meanwhile, the headless straight screw 8 can also block the lock cylinder body 3 from falling out of the lock cylinder groove 2, and because the fixing through hole 7 is communicated with the lock beam through hole 4, when the lock beam body 6 is inserted in the lock beam through hole 4, the lock beam body 6 can play a role of plugging the fixing through hole 7, therefore, before the lock beam body 6 is opened and removed, the lock cylinder body 3 cannot be detached, and because one end of the transmission rod 10 is matched and clamped with the driving end of the lock cylinder body 3, when the rotary drum in the lock cylinder body 3 is screwed by a key, the driving end of the lock cylinder body 3 drives the transmission rod 10 to rotate, since the locking groove 11 and the locking block 15 sliding in the connecting hole 12 are limited by the sliding block 14, and the balls 13 are arranged above the transmission rod 10 and below the sliding block 14, when the transmission rod 10 rotates to enable the clamping groove two 19 to rotate to the upper side, the bottom of the lowest one of the balls 13 is sunk into the clamping groove two 19, at the moment, the locking block 15 can move downwards to be separated from the clamping groove one 18 formed on the lock beam body 6, meanwhile, when the bottom of the lowest one of the balls 13 is sunk into the clamping groove two 19 due to the arrangement of the first spring 16 and the retainer ring 17, the first spring 16 in a compressed state is loosened and stretched, the locking block 15 is naturally pulled to move downwards to be separated from the clamping groove one 18, meanwhile, due to the arrangement of the second spring 21 and the T-shaped ejector rod 22, after the clamping groove one 18 is separated from the locking block 15, the lock beam body 6 is not limited any more, the second spring 21 is loosened and extended to push the T-shaped ejector rod 22 to push the lock beam body 6 out of the lock Liang Mangkong cylinder, so that the lock head of the padlock is conveniently opened, and because of the arrangement of the first spring 16, when the padlock is assembled, one end of the transmission rod 10 is more troublesome to extend into the locking groove 11, but the ball 13 can be pushed upwards to compress the first spring 16 through auxiliary tools such as a thimble and the like.

As shown in fig. 1, 2 and 3, in some embodiments, the opening end of the fixing through hole 7 is provided with a first sealing bolt 23, and the opening end of the locking groove 11 is provided with a second sealing bolt 24; the first sealing bolt 23 and the second sealing bolt 24 are used for sealing the bottoms of the fixing through holes 7 and the locking grooves 11 and preventing dust and sundries from entering the lock body 1.

As shown in fig. 1 and fig. 3, in some embodiments, a limiting block 25 is fixed at the lower end of the first sealing bolt 23, and a limiting chute 26 is formed on the lock beam body 6; through setting up stopper 25 and spacing spout 26 for lock beam body 6 can not rotate, also can not deviate from lock beam through-hole 4 completely simultaneously, avoid lock beam body 6 to drop and lose.

As shown in fig. 1, 3 and 4, in some embodiments, a side wall of the lock body 1 is provided with an ejection hole 27 penetrating into the transmission groove 9; when dismantling lock core body 3, after taking off no first straight screw 8, owing to the gap between lock core groove 2 and the lock core body 3 is less, can't directly pour lock core body 3, through ejecting hole 27, utilize jack-up needle to pierce ejecting hole 27 in, promote transfer line 10 and lock core body 3 removal from lock body 1.

As shown in fig. 2, in some embodiments, a water bar 28 is fixed on one side wall of the lock body 1, the water bar 28 is arranged on the outer side of the lock cylinder body 3, the inner side of the water bar is rotatably connected with a baffle plate 29, the lower end of the baffle plate 29 penetrates through an opening of the water bar 28 to be aligned with the lower surface of the lock body 1, and a magnet 30 is embedded and fixed in the middle of the baffle plate 29; through the setting of water bar 28 and baffle plate 29, avoid external rainwater to permeate into lock body 1 inside from the lockhole of lock core body 3 and the gap between lock core body 3 and the lock core groove 2, the setting of magnet 30 for baffle plate 29 can adsorb on the surface of lock core body 3, is difficult for separating under the condition of not applying external force.

Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present utility model, and the present utility model is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present utility model has been described in detail with reference to the foregoing embodiments.
