Preferably, the flat plate 21 is provided with a plurality of drill holes 27 penetrating through the flat plate 21, and the fixed block 1 is provided with a plurality of blind holes 28 coaxially corresponding to the drill holes 27 one by one.
When the door lock is used, the two fixing blocks 1 are respectively fixed in a wall body and a door body by using the mounting holes 20, the spline shaft 17 is inserted into the spline hole 16 and the handle 9 is rotated to enable the shift lever 11 to rotate, when the shift lever 11 rotates, the push rod 13 simultaneously rotates along with the shift lever 11 to generate displacement in the front-back direction and the up-down direction, the push rod 13 slides in the straight groove 14 due to the displacement in the front-back direction of the push rod 13, and the push rod 13 drives the locking block 5 to slide up and down through the straight groove 14 due to the displacement in the up-down direction of the push rod; the locking block 5 slides in the direction away from the slot 3 by using the operation, and the push rod 13 rotates along with the shift lever 11 in a circumferential manner, so that the effective moving distance of the locking block 5 is the rotating radius of the push rod 13 along the horizontal rotating shaft 12, referring to the attached drawing 6, when the push rod 13 rotates along with the shift lever 11 to drive the locking block 5 to cross the farthest distance between the locking block 5 and the slot 3, the shift lever 11 is blocked by the limiting groove 15 and cannot rotate continuously, the spline shaft 17 is shifted out at the moment, the locking block 5 generates a tendency of sliding towards the slot 3 by the elastic force of the first spring 7 and acts on the shift lever 11 through the push rod 13 to rotate the shift lever 11, but due to the blocking of the limiting groove 15, the shift lever 11 cannot rotate, and the vertical position of the locking block 5 is locked;
the stop block 4 penetrates through the flat plates 21, the stop block 25 is placed in the limiting sliding groove 24, then the two flat plates 21 forming the hinge are respectively aligned with the fixed blocks 1 on the wall body and the door body, the flat plates 21 are pushed towards the corresponding fixed blocks 1, the insertion blocks 22 are inserted into the slots 3, and the stop block 4 is inserted into the sliding groove 2; after the flat plate 21 is completely attached to the fixed block 1, the locking screw 29 penetrates through the through hole 9 on the stop block 4 and is screwed in the threaded hole 10, and the end part of the limiting sliding groove 24 on the stop block 4 presses the stop block 25 tightly, namely the flat plate 21 is pressed on the fixed block 1 by the stop block 4; in order to make the installation of the plate 1 more reliable, screws are used to thread through the bores 27 and into the blind holes 28, thereby achieving a secure connection of the plate 21 to the fixing plate 1.
After the installation, insert integral key shaft 17 in splined hole 16 again through hole 26 of stepping down, make locking piece 5 reverse cross the farthest distance of locking piece 5 with slot 3 through handle 19 antiport integral key shaft 17, spacing groove 15 does not produce the hindrance to the antiport of driving lever 11 this moment, locking piece 5 produces under the spring action of first spring 7 and slides and is close to locking hole 23 on the jack 22 in the slot 3, when locking piece 5 will insert in locking hole 23, the tip of riser 6 receives blockking of dog 4 and makes locking piece 5 can't continue to slide, this state is the state of waiting to trigger of locking piece 5.
When a lawbreaker tries to remove the hinge, the locking screw 29 and the screw in the drill hole 27 must be unscrewed to remove the plate 21, when the locking screw 29 is unscrewed, the stopper 4 slides towards the outside of the fixed block 1 under the elastic force of the second spring 8 to make the stopper 4 and the vertical plate 6 horizontally offset, when the stopper 4 and the vertical plate 6 are completely separated, the vertical plate 6 is no longer blocked, the locking block 5 slides into the locking hole 23 rapidly under the elastic force of the first spring 7, so that the insert block 22, namely the plate 21, is locked by the locking block 5 and cannot be pulled out from the fixed block 1, the purpose of locking the plate 21 is achieved, at the moment, the stopper 4 cannot slide into the fixed block 1 again due to being blocked by the vertical plate 6, and the other end of the limiting chute 24 is blocked by the stopper 25 to make the stopper 4 cannot be removed, so that the lawbreaker cannot see the structure in the fixed block 1 clearly, therefore, a cracking method cannot be found, and the illegal action is forced to be abandoned actively; meanwhile, after the locking block 5 is inserted into the locking hole 23, the push rod 13 is arranged at the closest distance from the locking hole 23 when the push rod 13 rotates around the horizontal rotating shaft 12, and the motion dead point between the push rod 13 and the locking block 5 is the motion dead point in the state, even if the stop block 4 is pulled out and detached, a lawbreaker cannot make the locking block 5 slide to the outside of the locking hole 23 by directly operating the locking block 5 or the vertical plate 6, and therefore the safety of the invention is further improved.
When the stop block 4 and the locking block 5 need to be reset, the spline shaft 17 is utilized to rotate the shift lever 11 again to enable the locking block 5 to slide out of the locking hole 23, the vertical plate 6 is reset at the moment and does not block the stop block 4 any more, the stop block 4 slides inwards, the locking screw 29 is screwed tightly, and the spline shaft 17 is pulled out after the operation is completed to enable the locking block 5 to be in a state to be triggered again.
In the use method, the stop block 4 is a fixing piece of the flat plate 21 and is also an obfuscation measure for lawless persons to arrange, and when the disassembly is carried out, the lawless persons can disassemble the screw after finding the screw, so that the locking device in the invention is triggered to fulfill the aim of preventing disassembly; however, the present invention provides another using method, the installation of each component is the same as the above method, except that the stopper 4 is not used and the through holes corresponding to the stopper 4 on the second spring 8 and the flat plate 21 are eliminated, and the locking block 5 is always inserted into the locking hole 23 after the installation, that is, the locking block 5 is always in the triggering state.
The two installation and use methods can achieve ideal anti-disassembly effects, the locking block 5 in the former method only enters a triggering state in the implementation process of disassembly, the locking block 5 is not in contact with the locking hole 23 in normal use, corrosion and adhesion between the locking block and the locking hole can be effectively avoided due to long-term contact, triggering failure when locking is needed or the locking block and the locking hole cannot be separated in normal disassembly are avoided, and the stopper 4 is used as a confusion item in the former method to attract the attention of lawbreakers, so that the splined hole 16 is prevented from being discovered and concerned; in the latter method, the locking block 5 is always in contact with the locking hole 23, real-time disassembly prevention can be realized without triggering, the problem of triggering failure possibly existing in the former method is solved, however, the locking block 5 and the locking hole 23 are inevitably corroded and adhered by the method, unlocking of the locking block 5 is not facilitated, the stop block 4 is not arranged in the latter method, lawless persons can easily pay attention to the position of the spline hole 16 and make cracking attempts on the position, and the risk of disassembly is increased.
In order to achieve better safety performance, the flat plate 21 can be provided with the shielding piece corresponding to the spline hole 16, so that the position of the spline hole 16 is difficult to find through external visual observation, the possibility of breaking the invention is reduced, and simultaneously, the spline tooth shapes of the spline hole 16 and the spline 18 can be set into irregular structures which are used unconventionally, so that lawless persons are difficult to find a proper tool for inserting.
When the worker needs to detach the hinge, the spline shaft 17 is inserted into the spline hole 16 according to the corresponding operation method, the handle 19 is rotated to enable the locking block 5 to slide out of the locking hole 23, and then the corresponding fastening screws are completely screwed down to pull out the flat plate 21.
The invention has exquisite structure and simple operation, can realize active protection on illegal hinge disassembly after being installed, and finally enables the illegal action to be forcibly stopped, thereby achieving the aim of disassembly prevention; meanwhile, the locking part is completely arranged in the fixed block, so that the locking part has high concealment and is not easy to be identified by lawless persons, the locking part can be effectively disassembled and assembled only by using the spline shaft, the lawless persons usually disassemble the screw in advance according to the conventional thinking to trigger the locking device, and the situation that the hinge is additionally provided with the anti-disassembling device is difficult to think; even if the position of the spline hole is found, lawless persons usually do not waste too much time to research and explore strange things after losing hands once, so that the risk of finding is prevented from being increased due to long-time residence, and the knowledge is difficult to get back.
In addition, different from the mode that the existing hinge is fixed by using expansion screws, the hinge is fixed on the fixed blocks arranged in the wall body and the door body, so that the reliability of the hinge fixation can be increased to a certain degree, and the risk that the hinge is separated from the wall body or the door body due to the fact that the expansion sleeve is pulled out when a large impact force is applied is avoided.
