[0021] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.
[0022] Please see Figure 1 and Figure 2The anti-theft lock box 1000 includes a housing 10, a base plate 20, a first anti-theft lock 30, a second anti-theft lock 40, a first key 50, and a second key 60. The housing 10 and the base plate 20 are rotatably connected. The first anti-theft lock 30 is disposed within the housing 10, and the second anti-theft lock 40 is located inside the housing 10. The second anti-theft lock 40 is used to connect or disconnect the housing 10 and the base plate 20. The first key 50 is used to open or close the first anti-theft lock 30, and the second key 60 is used to open or close the second anti-theft lock 40.
[0023] For the aforementioned housing 10 and base plate 20, as Figure 2 and Figure 3 As shown, the housing 10 and the base plate 20 are rotatably connected to form a receiving cavity 10a for accommodating a door lock. The base plate 20 rotates relative to the housing 10 to open or close the receiving cavity 10a. The housing 10 is provided with an opening 10b communicating with the receiving cavity 10a. In some embodiments, the receiving cavity 10a is located on the housing 10. It is understood that the rotatable connection between the housing 10 and the base plate 20 includes, but is not limited to, hinge connection, spherical joint connection, etc.
[0024] In some embodiments, the base plate 20 is provided with an installation notch 201. During actual installation, the door lock located on the door panel can enter the receiving cavity 10a through the installation notch 201. After that, the base plate 20 can be fixed to the door panel by fasteners such as screws and rivets. At this time, the user can open or close the receiving cavity 10a by rotating the housing 10, so that the door lock is in an exposed or covered state.
[0025] In some embodiments, please refer to the following: Figure 4 The housing 10 is provided with a first fixing member 101, which is located within the receiving cavity 10a and is fixedly connected to the housing 10. The bottom plate 20 is provided with a second fixing member 202, which is located within the receiving cavity 10a and is fixedly connected to the bottom plate 20. The second fixing member 202 and the first fixing member 101 are spaced apart and opposite to each other along a first direction. Under the action of the second anti-theft lock 40, the first fixing member 101 and the second fixing member 202 can be in a state of mutual connection or mutual disconnection. In the open state, the housing 10 and the base plate 20 can be either relatively fixed or relatively rotatable. For example, when the second anti-theft lock 40 is closed, the first fixing member 101 and the second fixing member 202 are connected through the second anti-theft lock 40, and the housing 10 and the base plate 20 are relatively fixed. At this time, the receiving cavity 10a cannot be opened. When the second anti-theft lock 40 is open, the first fixing member 101 and the second fixing member 202 are disconnected, and the housing 10 and the base plate 20 can rotate relative to each other, allowing the receiving cavity 10a to be opened. In some embodiments, the second fixing member 202 is located between the first fixing member 101 and the opening 10b.
[0026] In some embodiments, the base plate 20 and the housing 10 rotate relative to each other about a second direction as an axis, the second direction being perpendicular to the first direction. In some embodiments, the first direction extends along the length direction of the housing 10, and the second direction extends along the width direction of the housing 10.
[0027] In some embodiments, please refer to the following: Figure 5 The first fixing member 101 is provided with a first through hole 1011, and the second fixing member 202 is provided with a second through hole 2021. The second through hole 2021, the first through hole 1011, and the opening 10b are coaxially distributed along the first direction. The first through hole 1011 and the second through hole 2021 are used to install components in the second anti-theft lock 40, so as to realize the control of the connection state between the first fixing member 101 and the second fixing member 202 by using the second anti-theft lock 40.
[0028] Regarding the aforementioned second anti-theft lock 40 and second key 60, as Figure 2 As shown, the second anti-theft lock 40 is used to connect or disconnect the housing 10 and the base plate 20. The second anti-theft lock 40 and the opening 10b are arranged opposite each other along a first direction. One end of the second key 60 can extend into the receiving cavity 10a through the opening 10b to open or close the second anti-theft lock 40. When the second anti-theft lock 40 is closed, the housing 10 and the base plate 20 are connected and relatively fixed. When the second anti-theft lock 40 is open, the housing 10 and the base plate 20 are disconnected and can rotate relative to each other. The second key 60 is an external key.
[0029] Please refer to the following for details. Figure 5 and Figure 6 The second anti-theft lock 40 includes a locking screw 401, which passes through a second through hole 2021 and can move within the second through hole 2021 towards or away from the first through hole 1011. When the locking screw 401 passes through the first through hole 1011, the first fixing member 101 and the second fixing member 202 are connected, and the housing 10 and the base plate 20 are relatively fixed. At this time, the receiving cavity 10a cannot be opened. When the locking screw 401 does not pass through the first through hole 1011, the first fixing member 101 and the second fixing member 202 are disconnected, and the housing 10 and the base plate 20 can rotate relative to each other, allowing the receiving cavity 10a to be opened. The user can insert a second key 60 into the locking screw 401 through the opening 10b and rotate it counterclockwise or clockwise to move the locking screw 401 within the second through hole 2021 towards or away from the first through hole 1011.
[0030] In some embodiments, please refer to the following: Figure 7The second anti-theft lock 40 includes a locking nut post 402, which is installed in the first through hole 1011. When the locking screw 401 is screwed into the locking nut post 402, the locking screw 401 passes through the first through hole 1011. The locking nut post 402 can be used to connect the locking screw 401 to ensure the connection stability between the first fixing member 101 and the second fixing member 202.
[0031] In some embodiments, the locking screw 401 is provided with a locking thread 4011 at one end near the locking nut post 402. When the locking thread 4011 is screwed into the locking nut post 402, the first fixing member 101 and the second fixing member 202 are in a connected state. When the locking thread 4011 is not connected to the locking nut post 402, the first fixing member 101 and the second fixing member 202 are in a disconnected state.
[0032] In some embodiments, a limiting ring 403 is provided on the locking screw 401. The limiting ring 403 is located on the side of the second fixing member 202 closer to the first fixing member 101. When the locking screw 401 moves away from the first fixing member 101, the second fixing member 202 prevents the locking screw 401 from completely passing through the second through hole 2021 through the limiting ring 403. The limiting ring 403 can limit the movement displacement of the locking screw 401 on the second fixing member 202 to ensure that the locking screw 401 moves within a preset range. In some embodiments, an annular groove 4012 is provided on the locking screw 401, and the limiting ring 403 is engaged with the annular groove 4012.
[0033] In some embodiments, a limiting protrusion 4013 is provided at one end of the locking screw 401 away from the first through hole 1011. An elastic element 404 is sleeved on the locking screw 401 and located between the second fixing member 202 and the limiting protrusion 4013. The elastic element 404 applies a spring force to the locking screw 401 through the limiting protrusion 4013, causing it to move away from the first fixing member 101. The elastic element 404 can provide elastic recovery for the locking screw 401. When the locking screw 401 is disconnected from the locking nut post 402, the locking screw 401 moves away from the first fixing member 101 under the spring force of the elastic element 404, so as to reduce the interference caused by the locking screw 401 on the rotation between the housing 10 and the base plate 20.
[0034] In some embodiments, the elastic member 404 is located between the limiting ring 403 and the limiting protrusion 4013. When the locking screw 401 is disconnected from the locking nut post 402, under the elastic force of the elastic member 404, the locking screw 401 moves away from the first fixing member 101, and under the action of the limiting ring 403, the locking screw 401 is limited to a preset position on the second fixing member 202.
[0035] In some embodiments, please refer to the following: Figure 8 and Figure 9 The second anti-theft lock 40 also includes a fixing nut 405, which is disposed in the second through hole 2021. One end of the locking screw 401 passes through the fixing nut 405 and is threadedly engaged with the fixing nut 405. The fixing nut 405 can limit and fix the locking screw 401 to the second fixing member 202.
[0036] In some embodiments, the base plate 20 is further provided with a limiting member 203, which is spaced apart from the second fixing member 202. The limiting member 203 is located between the second fixing member 202 and the opening 10b. A portion of the locking screw 401 is located between the limiting member 203 and the second fixing member 202. When the locking screw 401 moves away from the first fixing member 101, the limiting member 203 can prevent the locking screw 401 from completely disengaging from the fixing nut 405. The limiting member 203 can limit the displacement distance of the locking screw 401 in the first direction, while reducing the chance of the locking screw 401 falling off the second fixing member 202. In some embodiments, the limiting member 203 is provided with a limiting hole 2031 for an external key to pass through. The limiting hole 2031 is for a second key 60 to pass through, and the second key 60 can pass through the opening 10b and the limiting hole 2031 in sequence to connect with the locking screw 401.
[0037] In some embodiments, the second anti-theft lock 40 further includes a pin sleeve 406, which is installed in the first through hole 1011. The locking screw 401 can pass through the first through hole 1011 through the pin sleeve 406. When the locking screw 401 is connected to the pin sleeve 406, the first fixing member 101 and the second fixing member 202 are in a connected state. When the locking screw 401 is not connected to the pin sleeve 406, the first fixing member 101 and the second fixing member 202 are in a disconnected state. When the locking screw 401 moves toward the first through hole 1011, the pin sleeve 406 can be used to connect the locking screw 401 to ensure a tighter connection between the first fixing member 101 and the second fixing member 202.
[0038] In some embodiments, please refer to the following: Figure 10The locking screw 401 includes a connecting portion 401a and a plug portion 401b connected to each other. The plug portion 401b is disposed closer to the first fixing member 101 than the connecting portion 401a. The connecting portion 401a is threadedly connected to the fixing nut 405. The plug portion 401b can move towards or away from the pin sleeve 406 in the second through hole 2021. When the plug portion 401b is inserted into the pin sleeve 406, the first fixing member 101 and the second fixing member 202 are in a connected state. When the plug portion 401b is not inserted into the pin sleeve 406, the first fixing member 101 and the second fixing member 202 are in a disconnected state. In some embodiments, the end of the plug portion 401b near the first fixing member 101 is tapered, which facilitates the insertion of the plug portion 401b into the pin sleeve 406.
[0039] Regarding the aforementioned first anti-theft lock 30 and first key 50, as Figure 2 As shown, a first anti-theft lock 30 is disposed on the housing 10. The first anti-theft lock 30 is used to open or close the opening 10b from inside the housing 10. A first key 50 is used to open or close the first anti-theft lock 30. The user can open or close the first anti-theft lock 30 by turning the first key 50 counterclockwise or clockwise. When the first anti-theft lock 30 is in the open state, the opening 10b is in the open state. At this time, the user can use the second key 60 to connect the second anti-theft lock 40 through the opening 10b. When the first anti-theft lock 30 is in the closed state, the opening 10b is in the closed state. At this time, the second key 60 cannot open or close the connection to the second anti-theft lock 40.
[0040] In some embodiments, the first anti-theft lock 30 includes a lock body 301 and a bolt 302. The bolt 302 is connected to the lock body 301 and is located within the receiving cavity 10a. When the lock body 301 is in a first state, the bolt 302 covers the opening 10b, and the opening 10b is in a closed state. When the lock body 301 is in a second state, the bolt 302 does not cover the opening 10b, and the opening 10b is in an open state. The first state refers to the state where the first key 50 closes the first anti-theft lock 30, and the second state refers to the state where the first key 50 opens the first anti-theft lock 30. When the first key 50 is turned, the lock body 301 can be used to rotate the bolt 302 to different positions to cover or open the opening 10b.
[0041] It should be noted that: Please refer to Figure 11In some embodiments, along the first direction, the first fixing member 101 is positioned closer to the opening 10b than the second fixing member 202. In this case, each component located on the second fixing member 202 in the above embodiments (e.g., locking screw 401, limiting retaining ring 403) is correspondingly installed on the first fixing member 101, and each component located on the first fixing member 101 in the above embodiments (e.g., locking nut post 402) is correspondingly installed on the second fixing member 202. That is, based on the above embodiments, the positions of the first fixing member 101 and the second fixing member 202 are interchanged.
[0042] In this embodiment of the utility model, a housing 10, a base plate 20, a first anti-theft lock 30, and a second anti-theft lock 40 are provided. The base plate 20 is rotatably connected to the housing 10 to form a receiving cavity 10a for accommodating the lock. The base plate 20 and the housing 10 rotate relative to each other to open or close the receiving cavity 10a. The housing 10 has an opening 10b communicating with the receiving cavity 10a. The first anti-theft lock 30 is disposed on the housing 10 and is used to open or close the opening 10b from inside the housing 10. The housing 10 and the base plate 20 are connected or disconnected via the second anti-theft lock 40. The second anti-theft lock 40 and the opening 10b are arranged opposite each other along a first direction. One end of a key can be inserted into the receiving cavity 10a through the opening 10b to open or close the second anti-theft lock 40. When the second anti-theft lock 40 is closed, the housing 10 and the base plate 20 are connected and relatively fixed. When the second anti-theft lock 40 is open, the housing 10 and the base plate 20 are disconnected and can rotate relative to each other. With this configuration, the user can achieve anti-theft protection for the door lock through the anti-theft lock box. The door lock is located in the receiving cavity 10a of the anti-theft lock box. The user can open the anti-theft lock box when needed. When closing the lock box, the first anti-theft lock 30 needs to be rotated to open the opening 10b. After the opening 10b is exposed, the second anti-theft lock 40 is inserted into the receiving cavity 10a through the opening 10b using an external key, so that the second anti-theft lock 40 is in the open state. At this time, the housing 10 and the base plate 20 are in the disconnected state, and the housing 10 and the base plate 20 can rotate relative to each other to open the receiving cavity 10a. Conversely, when the user needs to close the anti-theft lock box, the second anti-theft lock 40 is turned using an external key. 0, so that the second anti-theft lock 40 is in the closed state.
