[0004] Furthermore, a blocking groove is provided on the front side of the anti-drill plate, and a plug is embedded in the blocking groove; The plug has several ball grooves of different sizes, and each ball groove contains a steel ball of a corresponding size.

[0005] Furthermore, the anti-drill plate is attached to the outer panel of the cabinet door, the wear-resistant plate is attached to the inner panel of the cabinet door, and a gap is left between the anti-drill plate and the wear-resistant plate.

[0006] Furthermore, the locking mechanism includes An interlocking frame is located on the non-hinged side of the cabinet door; An interlocking head is mounted on the interlocking frame and passes through the lock holes of the cabinet door and the cabinet body respectively; An interlocking plate is located on the back of the cabinet door and has a horizontal guide groove and a vertical linkage groove, which are connected to the interlocking frame; the relocking mechanism and / or the back of the cabinet door is provided with a fixing bolt, which is inserted into the guide groove; An interlocking torsion member has one end connected to the transmission rod of the throttle via a locking mechanism, and the other end has an interlocking post on its front side. The interlocking post passes through the linkage groove, and the front end of the interlocking post abuts against the cabinet door back panel. The throttle rotates and, through the interlocking torsion member, causes the interlocking pin to move up and down in the linkage slot, which in turn causes the interlocking plate and interlocking frame to slide horizontally.

The anti-impact plate is an L-shaped plate that abuts against the cabinet, the front anti-impact baffle, and the rear anti-impact baffle, respectively, and is locked between the front anti-impact baffle and the rear anti-impact baffle to form a movable groove; The cone head of the cone bolt moves out of or into the movable groove in sync with the opening or closing of the cabinet door.

[0011] Furthermore, the hinged side of the cabinet door is square, and the non-hinged side of the cabinet door has an inwardly tapering section.

[0012] In summary, the present invention has the following beneficial effects: By setting up anti-drill plates with embedded steel balls on their surface, the damage to the cabinet door by drilling tools can be effectively prevented. The structure of the anti-drill plates is further complicated by the design of plugs with steel balls of different sizes, which enhances the anti-drilling ability. The wear-resistant plates are also used to improve the explosion-proof performance. By cleverly designing an anti-impact mechanism that does not hinder the opening and closing of the cabinet door, the structural strength of the weaker hinge side of the cabinet door is effectively improved when it is subjected to external impact, thereby enhancing the overall safety performance.

[0015] The following is in conjunction with the appendix Figure 1-6 The present invention will be described in further detail below.

[0016] Multiple explosion-proof safes, such as Figure 1 and Figure 3 As shown, the main body consists of a cabinet body 10 and a cabinet door 20 connected by hinges. The cabinet door 20 can rotate relative to the right side of the cabinet body 10, thus opening and closing the cabinet door 20. The right end of the cabinet body 10 is designated as the hinged side, and the left end as the non-hinged side. A main board is located in the center section of the cabinet door 20, with space left before and after the main board for mounting components. A steel plate is installed on the outer side, forming a three-layer structure in a broad sense. The hinged side of the cabinet door 20 is square, while the non-hinged side has a retractable section 21, designed to accommodate the opening process of the cabinet door 20.

[0017] An anti-drill plate 30 and a wear-resistant plate 40 are installed inside the shell structure at the front of the motherboard. For example... Figure 2 As shown, the anti-drill plate 30 is attached to the outer panel of the cabinet door 20. The wear-resistant plate 40 is attached to the inner panel of the cabinet door 20, which is the main panel in the center section of the cabinet door 20. It is best to leave a gap between the anti-drill plate 30 and the wear-resistant plate 40 to increase the difficulty for criminals to drill through these two layers of panels. After the anti-drill plate 30 is formed, it is a complete plate with several steel balls 31 embedded in it. It is actually made by welding the plates together. Several ball grooves are opened on the front of the anti-drill plate 30, and the corresponding steel balls 31 are embedded in the ball grooves. The size of the ball grooves is larger than the size of the steel balls 31 placed in them to ensure that the steel balls 31 have a certain amount of room to move. After the steel balls 31 are embedded, an anti-detachment plate is welded to the front of the anti-drill plate 30. The surface of the anti-detachment plate has round holes drilled corresponding to the openings of the ball grooves. The size of the round holes on the anti-detachment plate is smaller than the size of the ball grooves. After welding, it forms an obstruction and restriction effect on the steel balls 31 in the ball grooves, completing the operation of embedding the steel balls 31. In addition, a blocking groove is provided in the lower right corner of the anti-drill plate 30. The blocking groove is a stepped groove, wider at the outside and narrower at the inside. A plug 32 is embedded in the blocking groove, and several ball grooves of different sizes are opened in the plug 32. Steel balls 31 of corresponding sizes are also embedded in the ball grooves. The spherical structure of the steel balls 31 and its non-fixed design that allows them to move within a small range firstly makes it very difficult for external drilling. Secondly, the random placement of the steel balls 31, combined with the design of the plug 32 area, and the steel balls 31 of different sizes in the plug 32 area itself, creates considerable obstacles for criminals to drill.

[0018] like Figure 4 and Figure 5 As shown, the cabinet door 20 has a locking mechanism 50 on the non-hinged side and an anti-impact mechanism 60 on the hinged side. A relocking mechanism 70 is located on the back of the cabinet door 20, and it is linked to the locking mechanism 50. A lock disc 80 and a handle 90 are located on the front of the cabinet door 20. The lock disc 80 passes through the cabinet door 20 and connects to the relocking mechanism 70, which in turn is linked to the locking mechanism 50. Therefore, the lock disc 80 indirectly controls the locking mechanism 50. The handle 90 passes through the cabinet door 20 and connects to the locking mechanism 50. The lock disc 80 is either an electronic lock panel or a mechanical lock panel, functioning as a combination lock. Only when the correct password is entered can the relocking mechanism 70 and the locking mechanism 50 be unlocked. After the lock disc 80 is activated, turning the handle 90 is required to finally open the cabinet door 20.

[0019] like Figure 4 and Figure 5As shown, the locking mechanism 50 includes an interlocking frame 51, an interlocking plate 53, an interlocking torsion member 54, an interlocking pin, and a locking mechanism 56. The locking mechanism 56 is used to fix the main body of the locking mechanism 50 to the transmission rod through the cabinet door 20 via the throttle 90. The interlocking frame 51 is integrally located on the non-hinged side of the cabinet door 20, and is generally an L-shaped plate. The interlocking head 52 is located on the outer side of the interlocking frame 51, corresponding to the pre-set lock holes on the cabinet door 20 and the cabinet body 10. The interlocking head 52 passes through the lock holes to lock the cabinet door 20 to the cabinet body 10. The interlocking plate 53 is located on the back of the cabinet door 20, connected to the interlocking frame 51, and can slide horizontally. Specifically, the interlocking plate 53 has three horizontal guide slots 58 and one vertical linkage slot 55. Two guide slots 58 are aligned above the interlocking plate 53, and one guide slot 58 is located separately on the lower right side of the interlocking plate 53. Each guide slot 58 is fitted with a separate fixing bolt 71. The two upper fixing bolts 71 are mounted on the mounting plate of the heavy locking mechanism 70, and the lower fixing bolt 71 is mounted on the back of the main board of the cabinet door 20, achieving a three-point linkage limit function, allowing the interlocking plate 53 to slide horizontally only. One end of the interlocking torsion member 54 is fixed to the transmission rod of the throttle 90 via the locking mechanism 56, and the other end has an interlocking post on its front side. The interlocking post is inserted into the linkage slot 55 of the interlocking plate 53, and can move up and down within the linkage slot 55 as the interlocking torsion member 54 rotates. To maintain the stability of the overall structure, the front end of the interlocking post should ideally abut against the main board of the cabinet door 20. After the throttle 90 is activated by the locking disc 80, it rotates freely and drives the interlocking torsion member 54 to rotate synchronously. Naturally, the interlocking pin moves up and down in the linkage groove 55, which in turn drives the interlocking plate 53 and the interlocking frame 51 to slide horizontally synchronously. Finally, the interlocking head 52 leaves or enters the lock hole of the cabinet 10, realizing the opening or closing of the cabinet door 20. Among them, the locking mechanism 56 consists of two semi-circular fastening blocks 57 that can be aligned and spliced. The fastening blocks 57 have through and symmetrical bolt grooves on both sides in the vertical direction. After the bolt grooves of the two fastening blocks 57 are aligned, bolts are inserted to fix them, completing the tight pressing of the fastening blocks 57 on the transmission rod of the throttle 90. At the same time, the fastening blocks 57 press against the interlocking torsion member 54. Through the action of friction, the throttle 90 and its transmission rod are connected to the interlocking torsion member 54.

[0020] like Figure 4 and Figure 5As shown, the relocking mechanism 70 includes a lock body 72 with a latch, a relock seat 73, a relock rod 74, a relock spring 75, and a trigger plate 76. The interlock plate 53 has two separate lock slots at its top; one slot corresponds to the lock body 72, and the other corresponds to the relock rod 74. The lock body 72 is fixed to the main plate of the cabinet door 20, and its latch is normally engaged in one of the lock slots at the top of the interlock plate 53. The relock seat 73 corresponds to the other lock slot and is fixedly connected to the main plate of the cabinet door 20. It is a U-shaped plate with its opening facing the back. The relock rod 74 is vertically inserted through the relock seat 73 and suspended above the other lock slot. The relock spring 75 is fitted over the relock rod 74. One end of the relock spring 75 presses against the bottom of the upper fold of the relock seat 73, and the other end is fixedly connected to the relock rod 74. It is normally in a compressed state. The trigger plate 76 is an L-shaped sheet metal part; to ensure triggering, it can also be replaced with a glass plate. One end of the trigger plate 76 is connected to the back of the lock body 72, and the other end is pressed against the bottom of the heavy locking bar 74. When an external force forcibly breaks the cabinet door 20, the resulting impact will cause the trigger plate 76 to break, thereby releasing the restriction on the heavy locking bar 74. Under the action of the heavy locking spring 75, the heavy locking bar 74 quickly falls into the lock groove, directly locking the interlocking plate 53 and forming an irreversible locking state. The one-time heavy locking mechanism 70, which was originally located on the front of the cabinet door 20, is built into the cabinet to free up space on the front for the anti-drilling plate 30 and the wear-resistant plate 40, thereby enhancing the safe's anti-drilling performance without affecting the original design intent.

[0021] like Figure 6 As shown, the anti-impact mechanism 60 includes a conical bolt 61, an anti-impact front baffle 62, an anti-impact rear baffle 63, and an anti-impact retaining plate 64. An L-shaped space needs to be pre-formed on the hinge side of the cabinet 10. Within this space, the anti-impact front baffle 62 and the anti-impact rear baffle 63 are respectively installed one in front of the other. The anti-impact front baffle 62 and the anti-impact rear baffle 63 are supported and positioned by the anti-impact retaining plate 64 of the L-shaped plate. Multiple anti-impact retaining plates 64 are vertically arranged and simultaneously abut against the L-shaped space of the cabinet 10, the anti-impact front baffle 62, and the anti-impact rear baffle 63, thus forming the necessary movable groove 65 between the cabinet 10, the anti-impact front baffle 62, and the anti-impact rear baffle 63. The conical bolt 61 passes through the hinge side of the cabinet door 20, and its conical head corresponds to the movable groove 65. The length and taper of the conical bolt 61 need to be determined according to the size of the movable groove 65. The cone head of the cone bolt 61 is designed to move out of or into the movable groove 65 synchronously with the opening or closing of the cabinet door 20, without affecting the normal opening of the cabinet door 20. In this way, when the cabinet door 20 is damaged by external force, the cone bolt 61 and the movable groove 65 form a locking structure, preventing the hinged side of the cabinet door 20 from falling off or deforming directly after the hinge is damaged, thus improving the explosion-proof performance of the cabinet door 20.

[0022] In normal use, first open the lock body 72 via the lock disc 80 to release the restriction of the interlocking plate 53 by the relocking mechanism 70, then turn the handle to move the lock cylinder away from the keyhole and open the cabinet door 20. In the event of a breach by criminals, the anti-impact mechanism 60 locks the hinged side of the cabinet door 20 and the cabinet body 10; the relocking mechanism 70 locks the interlocking plate 53, that is, the interlocking cylinder locks the keyhole, locking the non-hinged side of the cabinet door 20 and the cabinet body 10.

[0023] It should be noted that this specific embodiment is merely an explanation of the present invention and is not intended to limit the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
