[0039] like Figures 1 to 3 and Figure 5As shown, the present application provides an anti-disassembly safe, including a cabinet 10, a cabinet door 20 rotatably arranged at the opening of the cabinet 10, and a lock mechanism 30. Among them, a cash outlet 11 is provided on the upper end surface of the cabinet 10, and the lock mechanism 30 includes a main lock body 31, a first limiter 32, and a second limiter 33. Specifically, a handle 21 and a password lock disk 22 connected to the main lock body 31 are provided on the outer wall of the cabinet door 20, the main lock body 31 and the first limiter 32 are both fixed to the inner wall of the cabinet door 20, a plug-in block 311 is provided on the side of the main lock body 31 facing the first limiter 32, the plug-in block 311 and the first limiter 32 are plugged and matched, and the second limiter 33 is fixed on the inner side wall of the opening of the cabinet 10 and is located on the side of the main lock body 31 away from the first limiter 32. Specifically, the cabinet 10 includes two side wall panels 12, a bottom plate 13 and a top plate 14, wherein the cash outlet 11 is opened on the top plate 14, the two side wall panels 12 are connected between the top plate 14 and the bottom plate 13, and the second stopper 33 is fixed on one side wall panel 12 opposite to the first stopper 32. The first stopper 32 and the second stopper 33 are distributed on opposite sides of the main lock body 31, the second stopper 33 and the main lock body 31 are spaced apart, and the spacing between the second stopper 33 and the main lock body 31 is less than the depth of the plug-in block 311 inserted into the first stopper 32.

[0040] The following is a further description of the anti-tampering safe provided in the embodiment of the present application: The anti-tampering safe provided in the embodiment of the present application, by providing a first limit piece 32 and a second limit piece 33 on opposite sides of the main lock body 31, and providing a plug-in block 311 on the side of the main lock body 31 facing the first limit piece 32, so that the main lock body 31 is fixed to the inner wall of the cabinet door 20 on the one hand, and is plugged and matched with the first limit piece 32 on the other hand, thereby achieving a stable assembly of the main lock body 31 in the cabinet 10 in both the front and side dimensions. When the anti-tampering safe is broken into from the inside by criminals through the cash outlet 11 on the cabinet 10, even if the connection between the main lock body 31 and the inner wall of the cabinet door 20 is destroyed, due to the distance between the second limit piece 33 and the main lock body 31 (such as Figure 5 L2 in FIG. 3 is smaller than the depth of the plug-in block 311 inserted into the first limiting member 32 (as shown in FIG. Figure 5 As shown in FIG. 1 , the main lock body 31 moves from the first limiter 32 to the second limiter 33 under the action of the demolition tool (the moving direction of the main lock body 31 is shown in FIG. 1 ). Figure 5 When the main lock body 31 is in contact with the second limit piece 33, the plug-in block 311 of the main lock body 31 is still inserted in the first limit piece 32, thereby ensuring that the main lock body 31 will not fall off the cabinet door 20, thereby effectively preventing the anti-breaking safe from being broken into from the inside, and significantly improving the safety of the anti-breaking safe.

[0041] In another embodiment of the present application, Figure 3 , Figure 4 and Figure 6 As shown, the first stopper 32 is provided with an assembly opening 321 on one side of the main lock body 31, and the plug-in block 311 is inserted into the assembly opening 321. Specifically, by providing the assembly opening 321 on the side of the first stopper 32 facing the main lock body 31, the plug-in block 311 and the assembly opening 321 are plugged in and matched, thereby realizing the overall plug-in match between the main lock body 31 and the first stopper 32.

[0042] Optionally, the first stopper 32 is in the shape of an elongated strip and is welded to the inner wall of the cabinet door 20. By setting the first stopper 32 in the shape of an elongated strip, on the one hand, the first stopper 32 can be prevented from occupying the assembly space in the cabinet body 10, and on the other hand, the overall strength of the first stopper 32 can be ensured, and its anti-disassembly capability can be ensured. By welding the first stopper 32 to the inner wall of the cabinet door 20, the firmness of the combination of the first stopper 32 and the cabinet door 20 is ensured, thereby further improving its anti-disassembly capability.

[0043] Optionally, the assembly opening 321 is opened along the length direction of the first position-limiting member 32, and the assembly opening 321 is a flat opening, and accordingly the plug-in block 311 is a block with a long strip cross section. By setting the assembly opening 321 as a flat opening, the assembly opening 321 can make full use of the assembly space in the length direction of the first position-limiting member 32, and can also make the width of the plug-in block 311 as wide as possible, so as to improve the strength of the plug-in block 311.

[0044] Optionally, a step-shaped plug 322 is further provided on one side of the first position-limiting member 32 facing the inner wall of the cabinet door 20, and the plug 322 is embedded and welded in the inner wall of the cabinet door 20. In this way, the stability of the first position-limiting member 32 disposed on the inner wall of the cabinet door 20 can be further improved, and by designing the plug 322 to be step-shaped, the accuracy of the plug 322 embedded in the corresponding notch of the inner wall of the cabinet door 20 can be improved, and the plug 322 can also provide a multi-dimensional limiting effect on the first position-limiting member 32. Preferably, the plug 322 can be symmetrically arranged at opposite ends of the first position-limiting member 32, so that the two plugs 322 of the first position-limiting member 32 can be fixed in the inner wall of the cabinet door 20 in a clamp-like manner, so that the first position-limiting member 32 is more firmly fixed on the inner wall of the cabinet door 20.

[0045] In another embodiment of the present application, Figure 6 As shown, the number of the plug-in blocks 311 and the assembly openings 321 are both multiple, and each plug-in block 311 and each assembly opening 321 are arranged in a one-to-one correspondence. Specifically, the number of the plug-in blocks 311 and the assembly openings 321 is preferably two, which can improve the stability of the plug-in fit between the main lock body 31 and the first stopper 32 on the one hand, and avoid the first stopper 32 from having too many assembly openings 321 on the first stopper 32, which would cause its strength to decrease.

[0046] In another embodiment of the present application, Figures 3 to 5 and Figure 7 As shown, the lock body mechanism 30 also includes a third limiter 34, which is fixed on the inner wall of the cabinet door 20 and is located on the side of the first limiter 32 away from the main lock body 31. The assembly opening 321 passes through the first limiter 32, and the plug-in block 311 extends out of the assembly opening 321 and is fixedly connected to the third limiter 34. Specifically, by providing the third limiter 34 and making the end of the plug-in block 311 extending out of the assembly opening 321 and fixedly connected to the third limiter 34, the presence of the third limiter 34 further strengthens the connection relationship between the main lock body 31 and the cabinet door 20, thereby making it more difficult for lawless elements to break into the main lock body 31, thereby further improving the security of the anti-breaking safe. At the same time, the distance between the third limiter 34 and the side panel wall 12 of the cabinet 10 close to it (such as Figure 5 L3 in the figure can be designed to be as small as possible to prevent the demolition tool from extending into the gap between the third limiting member 34 and the side panel wall 12.

[0047] In another embodiment of the present application, Figure 7 As shown, the third stopper 34 includes a connecting plate 341, a first side plate 342 and a second side plate 343. One side of the first side plate 342 is fixed to the inner wall of the cabinet door 20, and the other side of the first side plate 342 is bent and connected to the side of the connecting plate 341 away from the main lock body 31. The second side plate 343 is bent and connected to the side of the connecting plate 341 facing the main lock body 31, and the second side plate 343 is connected to an end of the plug-in block 311 extending out of the assembly opening 321. Specifically, by forming a bending transition at the connection between the first side plate 342, the second side plate 343 and the connecting plate 341, stress concentration will not occur at the connection between the first side plate 342, the second side plate 343 and the connecting plate 341, thereby ensuring the overall mechanical strength of the third stopper 34.

[0048] Optionally, the connecting plate 341, the first side plate 342 and the second side plate 343 are integrally formed. This ensures the structural uniformity and mechanical property consistency of the third stopper 34. Since the integral molding technology is suitable for mass production of parts, this also effectively reduces the manufacturing cost of the third stopper 34.

[0049] In another embodiment of the present application, Figure 7As shown, a connection hole 346 is formed on the second side plate 343, and a threaded hole 312 is formed on one end of the plug-in block 311 extending out of the assembly opening 321. The plug-in block 311 passes through the connection hole 346 and is inserted into the threaded hole 312 through the locking bolt 35 to achieve a detachable connection with the second side plate 343. Specifically, by passing the locking bolt 35 through the connection hole 346 and being inserted into the threaded hole 312, the second side plate 343 and the plug-in block 311 are detachably connected, thereby facilitating the rapid assembly of the third stopper 34 and the plug-in block 311.

[0050] In another embodiment of the present application, Figure 7 As shown, the third stopper 34 further includes a cover plate 344, and the connecting plate 341, the first side plate 342, and the second side plate 343 are surrounded to form an assembly cavity 345, and the assembly cavity 345 has an upper opening opened toward the top of the cabinet 10, and the cover plate 344 is sealed in the upper opening. Specifically, by making the connecting plate 341, the first side plate 342, and the second side plate 343 surround and form the assembly cavity 345, the bolt head of the locking bolt 35 can be accommodated in the assembly cavity 345, and is protected by the connecting plate 341, the first side plate 342, and the second side plate 343, so as to prevent the demolition tool from directly contacting the locking bolt 35 to damage the locking bolt 35. By sealing the covering plate 344 at the upper opening of the assembly cavity 345, the third limit member 34 protects the locking bolt 35 in four dimensions through the connecting plate 341, the first side plate 342, the second side plate 343 and the covering plate 344, further preventing the locking bolt 35 from being damaged by a demolition tool extending into the assembly cavity 345 through the upper opening of the assembly cavity 345 when the demolition tool extends into the cabinet 10 from the cash outlet 11 at the top of the cabinet 10 from top to bottom.

[0051] In another embodiment of the present application, Figure 7 As shown, the first side plate 342 is provided with a through hole 347, and the through hole 347 is provided corresponding to the connection hole 346, and the aperture of the through hole 347 is larger than the aperture of the connection hole 346. Specifically, by providing the through hole 347 at the position of the first side plate 342 corresponding to the connection hole 346, and making the aperture of the through hole 347 larger than the aperture of the connection hole 346, when the third stopper 34 is assembled with the plug-in block 311, the operator can insert the screwdriver into the through hole 347 to drive the locking bolt 35 through the connection hole 346 and screw it into the threaded hole 312, which significantly improves the convenience of assembling the third stopper 34 and the plug-in block 311. Optionally, a plurality of threaded holes 312 may be provided on a plug-in block 311, and the number of the connection hole 346 and the through hole 347 is also plural, so as to ensure the connection strength between the third stopper 34 and the plug-in block 311.

[0052] In another embodiment of the present application, Figures 3 to 5 As shown, the corners of the main lock body 31 are provided with fixing pieces 313, and the fixing pieces 313 are fixed to the inner wall of the cabinet door 20 by fastening screws 314. Specifically, the main body of the main lock body 31 can be welded and fixed to the inner wall of the cabinet door 20, and the fixing pieces 313 are screwed to the inner wall of the cabinet door 20 to enhance the connection stability between the main lock body 31 and the inner wall of the cabinet door 20. Optionally, fixing pieces 313 can be provided at all four corners of the main lock body 31 to further enhance the connection stability between the main lock body 31 and the inner wall of the cabinet door 20, and improve the force balance of the main lock body 31.

[0053] The above are only preferred embodiments of the present application and are not intended to limit the present application.
