Description

Technical Field

[0001] This utility model relates to the field of safe technology, and in particular to a rotating bolt structure for a safe. Background Technology

[0002] With economic development, people's demand for property security is increasing, the application of safes is becoming more widespread, and the security requirements for safes are also getting higher and higher.

[0003] Currently, most safe products on the market use a single bolt that enters the panel stop and locks in one direction. However, the anti-theft and security of this type of safe bolt does not meet the required standards, and therefore needs to be improved. Utility Model Content

[0004] This utility model provides a rotating bolt structure for safes that can be used in conjunction with the safe lock body to achieve double locking, thus providing double insurance and anti-theft protection and meeting higher security requirements. It solves the technical problem that the bolt structure of current safe products is too simple, and the anti-theft and security of the safe bolts do not meet the required requirements, thus failing to meet higher security requirements.

[0005] The above-mentioned technical problem of this utility model is solved by the following technical solution: a rotating bolt structure for a safe, including a bolt structure installed on the lock body of the safe panel, the lock body structure on the safe panel driving the bolt structure to move in the lock hole, the bolt structure including a bolt shell, the rear end of the bolt shell being connected to the lock body structure, the front end of the bolt shell being provided with a rotatable and limited bolt tongue, and the bolt shell being provided with a linkage mechanism for controlling the rotation of the bolt tongue. The bolt structure in this invention works in conjunction with the lock body structure on the safe's panel. The drive mechanism within the lock body structure moves the bolt structure within the keyhole. Since the electronic lock structure of safes is already very mature, it is not shown in the accompanying drawings. When locking, the lock body structure moves the bolt structure into the keyhole. During locking, the linkage mechanism rotates the bolt 90 degrees, resulting in a 90-degree misalignment between the bolt and the outer shell. This relative positioning of the bolt and the keyhole structure achieves the locked state. During unlocking, the lock body structure moves the bolt structure in the opposite direction, and the linkage mechanism rotates the bolt in the opposite direction. At this point, the bolt and the outer shell overlap at 0 degrees, allowing the safe to be opened normally. The bolt structure of this invention, in conjunction with the lock body structure of the safe, achieves a double-security effect, increasing the safety of the safe.

[0006] Preferably, the linkage mechanism includes a rotating rod fixedly connected to the bolt housing and the latch. A sleeve, which can slide relative to the rotating rod, is fitted over the rotating rod. A spiral guide groove is formed on the outer wall of the sleeve, and a guide block that slides along the guide groove is provided on the outer wall of the rotating rod. During the lateral reciprocating sliding of the sleeve, the rotating rod drives the latch to rotate synchronously. Depending on the sliding direction of the sleeve, the latch will exhibit two states: 90 degrees and 0 degrees, corresponding to the locked and unlocked states respectively. Combined with the lock body structure of the safe, this achieves a double security effect.

[0007] Preferably, the linkage mechanism further includes an actuating piece rotatably mounted on the outside of the sleeve, with the end of the actuating piece extending to the outside of the bolt housing and engaging with the lock hole structure. When locked, as the lock body structure moves the bolt structure into the lock hole, the actuating piece is blocked and actuated. During the actuation of the actuating piece, the sleeve slides to the left. During the movement of the sleeve, the rotating rod slides along the guide groove on the outer wall of the sleeve. Since the guide groove is a bolt groove, the rotating rod will cause the bolt to rotate 90 degrees. At this time, the bolt and the bolt housing are misaligned by 90 degrees, and the bolt and the lock hole structure are relatively limited, achieving the locked state.

[0008] Preferably, the sleeve surface is integrally formed with several limiting blocks, and the actuating piece is engaged between the limiting blocks. The sleeve surface is also formed with annular and cylindrical limiting blocks at intervals, and the actuating piece is engaged between two adjacent limiting blocks. When the actuating piece encounters resistance, it will drive the sleeve to move to the left.

[0009] Preferably, the actuating piece and the sleeve are relatively positioned and engaged by a protrusion and a sliding groove structure. The sleeve surface is integrally formed with a protrusion, while the actuating piece has a corresponding sliding groove. The two slide relative to each other and are positioned relative to each other. The sleeve will only move left and right and will not rotate relative to each other, ensuring the stability of the mechanism.

[0010] Preferably, the actuating piece is a multi-segmented, bent sheet-like structure. The multi-segmented actuating piece extends beyond the bolt housing, and during locking, it engages with the keyhole structure to trigger the linkage mechanism.

[0011] Preferably, the linkage mechanism further includes a spring sleeved between the sleeve and the bolt housing. In the locked state, the spring is compressed. When unlocking, the lock body structure drives the bolt structure to move in the opposite direction. Under the action of the spring, the sleeve slides to the right and releases the actuating plate. At this time, the rotating rod drives the bolt to slide back to its original position, and the bolt and bolt housing overlap, allowing the safe to be unlocked and opened normally.

[0012] Therefore, the rotating bolt structure of the safe of this utility model has the following advantages: it can be used with the safe lock body to achieve double locking, thus achieving double insurance and anti-theft effect and meeting the user's higher security needs.

[0022] The technical solution of the utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0023] Example: like Figure 1 and 2 As shown in Figures 3, 4, 5, 6, 7, and 8, a safe rotating bolt structure includes a bolt structure mounted on a lock body structure on a safe panel. The lock body structure on the safe panel drives the bolt structure to move within a keyhole. The bolt structure is mounted on a lock plate 1 of the lock body structure.

[0024] The bolt structure includes a bolt housing 2 fixed on the lock plate 1, a rotatable and limited bolt tongue 3 installed at the end of the bolt housing 2, and a linkage mechanism for controlling the rotation of the bolt tongue 3 installed inside the bolt housing 2.

[0025] The linkage mechanism includes a rotating rod 4 slidably installed inside the bolt housing 2, with the end of the rotating rod 4 fixedly connected to the bolt tongue 3. A sleeve 5 that can slide relative to the rotating rod 4 is installed on its outer sleeve. The outer wall of the sleeve 5 has a spiral guide groove 6, and the outer wall of the rotating rod 4 has an integrally formed guide block 7 that can slide along the guide groove 6.

[0026] A spring 8 is fitted between the sleeve 5 and the bolt housing 2.

[0027] The linkage mechanism also includes an actuating piece 9 rotatably mounted on the outside of the sleeve 5. The outer wall of the sleeve 5 is formed with annular and cylindrical limit blocks 10 at intervals, and the actuating piece 9 is stuck between two adjacent limit blocks 10.

[0028] The actuating piece 9 and the sleeve 5 are relatively limited and engaged by the sliding groove structure and the protrusion structure.

[0029] The actuating piece 9 is a multi-segmented bent sheet structure, and the end of the actuating piece 9 extends to the outside of the bolt housing 2 to cooperate with the lock hole structure.

[0030] The bolt structure in this invention is used in conjunction with the lock body structure on the safe panel. The drive mechanism inside the lock body structure can drive the bolt structure to move within the keyhole.

[0031] In this invention, the sleeve 5 can only move horizontally back and forth in cooperation with the sliding groove and protrusion structure of the actuating piece 9, and will not rotate relative to each other.

[0032] When locked, the lock body structure moves the bolt structure into the lock hole, and the actuating piece 9 is blocked and actuated. During the actuation of the actuating piece 9, the sleeve 5 slides to the left. During the movement of the sleeve 5, the rotating rod 4 slides along the guide groove 6 on the outer wall of the sleeve 5. Since the guide groove 6 is a bolt groove, the rotating rod 4 will drive the bolt 3 to rotate 90 degrees. At this time, the bolt 3 and the bolt housing 2 are in a 90-degree misalignment state. The bolt 3 and the lock hole structure are relatively limited, and the locking state is achieved. At this time, the spring 8 is in a compressed state.

[0033] When unlocking, the lock body structure drives the bolt structure to move in the opposite direction. Under the action of the spring 8, the sleeve 5 slides to the right and releases the contact piece 9. At this time, the rotating rod 4 drives the bolt 3 to slide in the opposite direction and reset. The bolt 3 and the bolt housing 2 are in an overlapping state, and the safe can be unlocked and opened normally.

[0034] The specific embodiments described herein are merely illustrative examples of the present invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this invention or exceeding the scope defined by the appended claims.
