Description

TECHNICAL FIELD

[0001] The present application relates to a lock box with a panel convenient to disassemble. BACKGROUND

[0002] Locks are one of the commonly used items in people's life. Generally, locks only realize the function of locking target objects, and users need to carry keys or room cards, which is inconvenient and has the risk of forgetting or losing. Therefore, key boxes for storing keys or room cards are in great demand.

[0003] Chinese patent CN106174995A intelligent key box discloses a structure of rotating connection between the shell and the front panel. As shown in the drawings of the specification, the hinge shaft between the rear panel and the front panel is installed from the outside to the inside, specifically, it is inserted from one end of the rear panel, passes through the front panel, and reaches the other end of the shell. The hinge shaft cannot be taken out after being blocked by the other end of the rear panel. In order to prevent cracking after installation, the hinge shaft does not protrude outward to provide an opportunity for people to take it out. Therefore, when the front panel is damaged and needs to be replaced, the user cannot conveniently separate the front panel from the rear panel, and can only throw away the whole key box. In addition, if the rear panel is fixed to an external object and cannot be easily loosened, and the front panel needs to be repaired due to damage, the user cannot conveniently separate the front panel from the rear panel by taking out the hinge shaft, and can only perform on-site repair, which affects the convenience of repair. Therefore, it is necessary to design a lock box with a panel convenient to disassemble to solve the above problems.

[0004] In addition, the above-mentioned Chinese patent CN106174995A intelligent key box needs to press the corresponding keys or marks on the password input device or the controller performs the locking action control when there is no input within the set time when locking. However, it does not disclose how to detect whether the front panel and the rear panel are in place. It exists the situation that the lock is automatically locked when it is not in place and there is no input within the set time. The existing proximity switch for in-place detection is mainly arranged and exposed on the side surface of the first object facing the second object so as to be triggered by the second object when in place. When the user touches the first object, the mis-triggering of the proximity switch may occur. If the proximity switch is used with the locking mechanism, the mis-triggering may cause the first object and the second object to be locked when they are not in place, and the lock tongue is driven to extend. Therefore, the extension of the lock tongue will hinder the in-place action between the first object and the second object, and the components are easy to be damaged by collision. Therefore, it is necessary to solve this problem. SUMMARY

[0017] Compared with the prior art, the present application has the following beneficial effects:

[0018] 1. The structure is simple and easy to realize, the first spring in the transverse channel of the first connecting portion of the box body is arranged to facilitate the elastic pressing of the two hinge shafts on both sides into the shaft holes of the second connecting portion of the panel during assembly until the blocking portion is encountered, thereby realizing the rotational connection between the box body and the panel, the gap between the outer side wall surface of the second connecting portion and the hole opening surface of the shaft hole is arranged to facilitate the user to manually or through a tool to press the hinge shaft to the inside of the transverse channel when disassembling the panel, so that the hinge shaft is separated from the shaft hole to facilitate the separation of the panel and the box body, and the utility is good; when the panel and the box body are closed together, the gap is not exposed, which is beneficial to prevent illegal users from manually or through a tool to press the hinge shaft to the inside of the transverse channel, and when the panel and the box body are opened to the position, the gap is exposed on the inside of the panel, which is convenient to ensure that the legal user can open the lock box or through a tool to press the hinge shaft to the inside of the transverse channel, and the utility is good.

[0019] 2. The third connecting part on the box body described in this case is provided to facilitate cooperation with the first connecting part to limit the second connecting part of the panel, avoiding the situation where the left end of the second connecting part on the left side is exposed outward and is easily pried, or the right end of the second connecting part on the right side is exposed outward and is easily pried. It has good practicality. In addition, the through hole of one of the third connecting parts makes it convenient to drill the transverse channel from this side through the through hole towards the first connecting part during specific manufacturing. It is easy to implement.

[0020] 3. The provision in this case that one of the shaft holes passes through the second connecting part facilitates drilling another shaft hole with a blind hole on the second connecting part during the actual manufacturing process. Then, the outer end of the through shaft hole is inserted, fixed and sealed by the blocking member, which is convenient to implement.

[0021] 4. The shaft hole where the blocking member is located is far from the through hole. In specific implementation, even if the blocking member can be subjected to force and continue to move in the direction of the transverse channel in its shaft hole, since it is not exposed on the side of the through hole, the unauthorized user cannot apply a transverse force to the blocking member and cause it to continue to move in the direction of the transverse channel in its shaft hole and separate from the shaft hole due to the obstruction of the third connection part on the other side, thus improving safety.

[0022] 5. The proximity switch in the panel is designed to be pressed against by the column extending into the first channel only when the panel is closed, so that the control module can control the electric mechanism to drive the bolt to extend towards the first channel. When the panel is not closed, the column cannot press against the proximity switch. In addition, it is not easy for the user to touch the proximity switch while passing through the first channel, which helps to avoid accidental triggering by the user and has good practicality. Furthermore, this design does not use a spring elastic drive structure to automatically extend the bolt, but instead uses the action of the electric mechanism to drive the bolt to extend from the second channel towards the first channel. This helps to increase the locking force of the bolt when locking the lock, which has good practicality. The first hemispherical surface of the bolt is designed so that when the panel is flipped up, the bolt is retracted from the first channel towards the second channel by the wall force at the lock opening, without the electric mechanism obstructing the bolt from retracting from the first channel to the second channel. Thus, this design does not require a separate mechanism to actively drive the bolt to retract, which has good practicality. Attached Figure Description

[0035] The following examples further illustrate the features and other related characteristics of the present invention in detail, to facilitate understanding by those skilled in the art:

[0036] like Figures 1 to 12As shown, a lock box with a detachable panel comprises a box body 1, a panel 2 for opening / closing the box body 1 is connected to the box body 1 through a rotating connection mechanism, a locking mechanism for locking after closing is arranged between the panel 2 and the box body 1, the rotating connection mechanism comprises a first connecting part 3 arranged on the box body 1, left and right second connecting parts 4 arranged on the panel 2 and distributed on the left and right sides of the first connecting part 3, a horizontal channel 31 is arranged in the first connecting part 3, two ends of the horizontal channel 31 are respectively provided with hinge shafts 5 capable of moving left and right, a first spring 6 is pressed between the two hinge shafts 5, one end of the second connecting part 4 facing the first connecting part 3 is provided with an axis hole 41 corresponding to the position of the horizontal channel 31 for the corresponding hinge shaft 5 to extend into, the box body 1 and the panel 2 can rotate relative to each other through the hinge shaft 5, a blocking part 411 is arranged in the axis hole 41 for preventing the hinge shaft 5 from excessively extending from the horizontal channel 31 to the axis hole 41, a gap 42 is arranged between the outer wall surface of the second connecting part 4 and the hole opening surface of the axis hole 41, which communicates with the inner cavity of the axis hole 41, for facilitating the user to manually or through a tool to press the hinge shaft 5 to the inside of the horizontal channel 31 when detaching the panel 2, the gap 42 is not exposed when the panel 2 and the box body 1 are closed together, and the gap 42 is exposed inside the panel 2 when the panel 2 and the box body 1 are opened to the position.

[0037] As described above, the structure is simple and easy to implement, the first spring 6 in the horizontal channel 31 of the first connecting part 3 of the box body 1 facilitates the elastic pressing of the two hinge shafts 5 on both sides into the axis hole 41 of the second connecting part 4 of the panel 2 during assembly until the blocking part 411 is encountered, thereby realizing the rotating connection between the box body 1 and the panel 2, the gap 42 between the outer wall surface of the second connecting part 4 and the hole opening surface of the axis hole 41 facilitates the user to manually or through a tool to press the hinge shaft 5 to the inside of the horizontal channel 31 when detaching the panel 2, which separates the hinge shaft 5 from the axis hole 41 to facilitate the separation of the panel 2 and the box body 1, and has good practicability; the gap 42 is not exposed when the panel 2 and the box body 1 are closed together, which is beneficial to prevent illegal users from manually or through a tool to press the hinge shaft 5 to the inside of the horizontal channel 31, and the gap 42 is exposed inside the panel 2 when the panel 2 and the box body 1 are opened to the position, which facilitates the legal user to press the hinge shaft 5 to the inside of the horizontal channel 31 after opening the lock box, and has good practicability.

[0038] As Figure 2 , Figure 3 , Figure 4As shown, in actual implementation, the left and right sides of the box body 1 are further respectively provided with third connecting parts 7, and a space for limiting the second connecting part 4 is formed between the first connecting part 3 and the third connecting part 7. The outer side of one of the third connecting parts 7 is provided with a through hole 71 in the same straight line as the transverse channel 31.

[0039] As described above, the third connecting part 7 on the box body 1 is arranged to facilitate cooperation with the first connecting part 3 to limit the second connecting part 4 of the panel 2, thereby avoiding the left end of the left second connecting part 4 from being easily pried and the right end of the right second connecting part 4 from being easily pried, and having good practicability. In addition, the through hole 71 of one of the third connecting parts 7 facilitates drilling the transverse channel 31 from the side through the through hole 71 to the first connecting part 3 in actual manufacture, and is convenient to implement.

[0040] As Figure 4 shown, in actual implementation, one of the shaft holes 41 penetrates the second connecting part 4, and a blocking piece 8 is inserted and fixed at the end of the shaft hole 41 away from the first connecting part 3. The end of the blocking piece 8 facing the hinge shaft 5 is the blocking part 411, and the other shaft hole 41 is a blind hole, and the hole bottom of the blind hole is the blocking part 411.

[0041] As described above, the arrangement of one of the shaft holes 41 penetrating the second connecting part 4 facilitates drilling the other shaft hole 41 in the second connecting part 4 as a blind hole in actual manufacture, and then inserting and fixing the outer end of the penetrating shaft hole 41 with the blocking piece 8 to block it, which is convenient to implement.

[0042] As Figure 4 shown, the shaft hole 41 where the blocking piece 8 is located is away from the through hole 71. In actual implementation, even if the blocking piece 8 can continue to move in the shaft hole 41 in the direction of the transverse channel 31 under force, since it does not appear on the side of the through hole 71, illegal users cannot exert a transverse force on the blocking piece 8 to make it continue to move in the shaft hole 41 in the direction of the transverse channel 31 and separate from the shaft hole 41 due to the obstruction of the other third connecting part 7, and the security is better.

[0043] As Figure 1 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12As shown, in particular implementation, the locking mechanism includes a column 11 arranged in the box body 1, a first channel 21 arranged inside the panel 2 for the column 11 to extend into when the panel 2 is closed, the first channel 21 is bypass connected with a second channel 22, the side wall of the column 11 is provided with a lock port 111 corresponding to the position of the second channel 22 after the panel 2 is closed, the second channel 22 is provided with a lock bolt 23 capable of extending from one side to the first channel 21 to cooperate with the lock port 111 to realize the locking function, the panel 2 is further provided with an electric mechanism 24 for driving the lock bolt 23 to extend from the second channel 22 to the first channel 21 or for not hindering the lock bolt 23 to retract from the first channel 21 to the second channel 22, a control module 25 for controlling the action of the electric mechanism 24, a proximity switch 26 located in or behind the first channel 21 for being pressed by the part of the column 11 extending into the first channel 21 when the panel 2 is closed in place so that the control module 25 controls the electric mechanism 24 to drive the lock bolt 23 to extend to the first channel 21, the end of the lock bolt 23 facing the lock port 111 is provided with a first hemispherical surface 231 for retracting the lock bolt 23 from the first channel 21 when the panel 2 is lifted by the force of the wall at the lock port 111, and the outside of the panel 2 is provided with a user unlocking input module 10 electrically connected with the control module 25.

[0044] As described above, the arrangement of the proximity switch 26 in the panel 2 is for being pressed by the part of the column 11 extending into the first channel 21 when the panel 2 is closed in place so that the control module 25 controls the electric mechanism 24 to drive the lock bolt 23 to extend to the first channel 21, and the column 11 fails to press the proximity switch 26 when the panel 2 is not closed in place, and the user himself cannot easily touch the proximity switch 26 through the first channel 21, which is beneficial to avoid the occurrence of user mis-triggering and has good practicability; in addition, the structure of the spring elastic driving the lock bolt 23 to automatically extend is not adopted in the case, but the action of the electric mechanism 24 is used to drive the lock bolt 23 to extend from the second channel 22 to the first channel 21, which is beneficial to improve the force of the lock bolt 23 locking the lock port 31 and has good practicability, and the arrangement of the first hemispherical surface 231 of the lock bolt 23 is beneficial to retract the lock bolt 23 from the first channel 21 to the second channel 22 under the condition that the electric mechanism 24 does not hinder the lock bolt 23 to retract, and the lock bolt 23 is retracted from the first channel 21 to the second channel 22 by the force of the wall at the lock port 31 when the panel 2 is lifted, which does not need to additionally arrange a mechanism for actively driving the lock bolt 23 to retract and has good practicability.

[0045] AsFigure 11 , Figure 12 As shown, in a specific implementation, the top side of the column 11 is provided with a first inclined surface 112, which facilitates pressing against the first hemispherical surface 231 and retracting the latch 23 from the first channel 21 to the second channel 22 when the panel 2 is closed. In this way, when the panel 2 is closed, the column 11 can more easily press against the first hemispherical surface 231 and retract the latch 23 from the first channel 21 to the second channel 22, which is practical.

[0046] like Figure 7 , Figure 8 , Figure 10 As shown, in a specific implementation, the electric mechanism 24 includes a motor 241 controlled by the control module 25 and a drive block 242 driven by the motor 241 to rotate. The outer periphery of the drive block 242 is provided with a convex arc surface 2421 for driving the latch 23 to extend from the second channel 22 to the first channel 21 when facing the latch 23, and a concave arc surface 2422 for not obstructing the latch 23 from retracting from the first channel 21 to the second channel 22 when facing the latch 23. A rounded corner is provided between the convex arc surface 2421 and the concave arc surface 2422. The end of the latch 23 facing the drive block 242 is provided with a second hemispherical surface 232.

[0047] As described above, compared with the technical solution of driving the latch 23 to extend and retract entirely through the push-pull action of the push-pull mechanism, the convex arc surface 2421 and concave arc surface 2422 of the drive block 242 in this case do not require the drive block 242 and the latch 23 to be connected together by a connector, which makes assembly convenient.

[0048] like Figure 7 , Figure 8 , Figure 10 , Figure 11 As shown, in a specific implementation, the uprights 11 in the box 1 are two distributed left and right, and the corresponding first channels 21 on the inner side of the panel 2 are two distributed left and right. Each first channel 21 is connected by a bypass to a second channel 22 located between the left and right first channels 21. Each second channel 22 is provided with a locking tongue 23 that can extend from one side to the first channel 21. The driving block 242 is located between the left and right second channels 22. The outer periphery of the driving block 242 has two convex arc surfaces 2421 and two concave arc surfaces 2422, which are circumferentially spaced. There are rounded corners between adjacent convex arc surfaces 2421 and concave arc surfaces 2422. This helps to improve the locking force between the box 1 and the panel 2.

[0049] like Figure 9As shown, in a specific implementation, a limiting opening / first limiting part 20 is provided at the junction of the first channel 21 and the second channel 22 to prevent the locking tongue 23 from excessively extending from the second channel 22 toward the first channel 21.

[0050] like Figure 7 , Figure 8 As shown, a first base 201 is detachably and fixedly connected to the inner side of the panel 2 by screws. The first base 201 is provided with a first channel 21, a second channel 22, and an electric mechanism 24. The proximity switch 26 is located between the panel 2 and the first channel 21 of the first base 201. A cover 202 for opening / closing the second channel 22 and the electric mechanism 24 is detachably and fixedly connected to the first base 201 by screws. This facilitates the installation and disassembly of components during specific implementation.

[0051] Additionally, such as Figure 11 As shown, in a specific implementation, the box body 1 is also provided with a spring post 12 for elastically pressing the panel 2 outward when the panel 2 is closed. In this way, after the locking mechanism is unlocked, the panel 2 is lifted up by the force of the spring post 12 to open the box body 1, which is practical.

[0052] As stated above, this case protects a lock box with a panel that is easy to disassemble, and all technical solutions with the same or similar structure as this case should be considered to fall within the scope of protection of this case.
