DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] The following further describes the utility model in conjunction with the drawings and embodiments. Embodiment
[0018] As Figures 1 to 3 shown, the utility model provides an industrial cabinet lock with an emergency unlocking function, which specifically includes a door panel 1, a lock core 2, a large convex block 3, a lock tongue 4, a nut part 5, a first rivet 6, a dye stick 7 and a second rivet 8;
[0019] Among them, the lock core 2 penetrates through the door panel 1 rotatably, a large convex block 3 is fixedly arranged at the rear end of the lock core 2, a lock tongue 4 is arranged on the lock core 2, a nut part 5 is in threaded fit with one end of the lock core 2 for unlocking, and the nut part 5 and the lock core 2 are connected by a first rivet 6 to facilitate emergency unlocking;
[0020] Among them, a dye stick 7 is fixedly arranged between the nut part 5 and the door panel 1, and a second rivet 8 is inserted outside the nut part 5 to seal the outlet of the dye stick 7, so as to facilitate showing whether the lock has been emergently opened.
[0021] In the present utility model, in addition to the necessary normal unlocking, it also has an emergency unlocking function. When the lock is in a locked state and the key is lost, and it is necessary to urgently open the lock, tools such as a wrench can be used to forcibly turn the nut member 5. In this way, the dye stick 7 between the nut member 5 and the door panel 1 is forcibly broken, and the difficult-to-clean dye in the dye stick 7 will ooze out. By observing whether the dye oozes out, it can be judged whether the emergency unlocking function has been used. At the same time, there is no obstruction of the dye stick 7 between the nut member 5 and the door panel 1, and it can rotate freely. Since the lock core 2 and the nut member 5 are connected by a threaded fit and can be rotated, the lock core 2 and the nut member 5 are connected by the first rivet 6. In this way, the lock core 2 and the nut member 5 are connected and fixed. After the dye stick 7 is broken, by turning the nut member 5, the lock core 2 can rotate relative to the door panel 1, and the lock tongue 4 in the locked state rotates to a suitable position with the lock tongue 4, then the door panel 1 can be opened. In addition, when installing this lock, first pass through and install the lock core 2 in the door panel 1, and the large convex block 3 will abut against the door panel 1 for a limit. At the same time, since the lock core 2 and the nut member 5 are first connected by a threaded fit, the number of turns of the nut member 5 can be used to adapt to the thickness of the door panel 1, and the lock core 2 and the nut member 5 are fixedly connected by the first rivet 6. Install the insertable and extractable dye stick 7 between the nut member 5 and the door panel 1 so that the lock core 2 cannot rotate. At the same time, install the second rivet 8 outside to seal the outlet of the dye stick 7. In addition, the first rivet 6 and the second rivet 8 can prevent the lock from being disassembled artificially, and at the same time can prevent the unauthorized unlocking person from restoring the lock after opening it privately, preventing the second rivet 8 from being removed and the dye stick 7 from being removed. This also shows that the emergency function can only be used once, because the second rivet 8 cannot be removed and the dye stick 7 cannot be removed for replacement, and the dye is difficult to clean. After the emergency function is used, a new lock and door panel 1 need to be replaced to ensure the safety of the industrial cabinet. Embodiment
[0022] As Figure 1 and Figure 3 shown, on the basis of Embodiment 1, it specifically further includes a nut cover 9 and an external screw 10. The nut cover 9 is fixedly arranged outside the nut member 5, and the nut cover 9 and the door panel 1 are connected by the external screw 10.
[0023] Judging from the appearance, the lock has no difference from ordinary locks. This is because a nut cover 9 is also provided outside the nut member 5. By tightening the external screw 10 between the nut cover 9 and the door panel 1, the nut cover 9 can be fixed on the nut member 5, so that the first rivet 6 and the second rivet 8 on the nut member 5 are hidden. By unscrewing the external screw 10 between the nut cover 9 and the door panel 1, the nut cover 9 can be removed from the nut member 5, and in this way, the nut member 5 is exposed behind the nut cover 9. In addition, the nut cover 9 also has the function of strengthening the lock core 2, further ensuring that the lock core 2 and the door panel 1 do not rotate relative to each other when emergency unlocking is not required.
[0024] As Figure 1And Figure 3 As shown in the figure, on the basis of Embodiment 1, it specifically further includes a washer 11 and a dye tank 12. The washer 11 is slidably arranged on the lock core 2 and is located between the door panel 1 and the nut member 5. The dye tank 12 is opened at equal angles behind the washer 11.
[0025] The washer 11 can fill the gap between the door panel 1 and the nut member 5, ensure the tight connection between the lock core 2 and the door panel 1, prevent loosening. At the same time, the dye tank 12 opened on the washer 11 can better seep out the dye on the dye stick 7, and can better show whether the emergency unlocking function of the lock has been used.
[0026] As Figure 3 shown, on the basis of Embodiment 1, it specifically further includes a counterbore 13. The first rivet 6 and the second rivet 8 are provided with counterbores 13 at the connection holes of the nut member 5.
[0027] Counterbores 13 are opened at the positions where the first rivet 6 and the second rivet 8 are inserted into the nut member 5, so that the rivet caps can be placed in the counterbores 13 to prevent the rivets from being pried open.
[0028] As Figure 1 and Figure 3 shown, on the basis of Embodiment 1, a plastic sleeve is sleeved on the lock tongue 4.
[0029] A plastic sleeve is sleeved on the head of the lock tongue 4. Through the plastic sleeve, the wear between the lock tongue 4 and the door panel 1 can be reduced, and at the same time, the rotation of the lock tongue 4 can be made smoother.
[0030] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claimed rights.
