Technical Field

[0001] This utility model relates to the field of delivery safe technology, specifically a waterproof and theft-proof package delivery combination box structure. Background Technology

[0002] With the rapid development of e-commerce and logistics, express delivery has become an important part of daily life. Traditional fixed mailboxes or simple drop boxes have limited functions and significant shortcomings in terms of security, waterproofing, and intelligence. Meanwhile, the fast pace of modern life has created an urgent need for intelligent delivery facilities that can operate 24 / 7 without face-to-face interaction. Existing solutions often only meet the single function of delivery or sending, and generally suffer from problems such as susceptibility to rainwater penetration, limited anti-theft measures, and inability to be remotely managed, making it difficult to guarantee the security of users' property and privacy.

[0003] Therefore, we propose a waterproof and theft-proof package delivery box structure to solve the above problems. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a waterproof and anti-theft package delivery combination box structure, which solves the problems mentioned in the background art, such as insufficient anti-theft and waterproof performance, single function, lack of integrated independent package sending and receiving functions, and reliance on manual operation.

[0005] (II) Technical Solution To achieve the above objectives, this utility model specifically adopts the following technical solution: A waterproof and theft-proof package delivery box structure includes: The box includes a mail box, a mail receiving box, and a delivery hopper; each of these is equipped with a mail box door, a mail receiving box door, and a delivery hopper. The mail box is an independent and enclosed mail storage area. The receiving box and the delivery hopper are isolated by a dynamic, relatively enclosed space formed by the delivery hopper during delivery. After the delivery hopper is closed, the receiving box is connected to the mail box for storage. The box is equipped with a baffle at the position corresponding to the delivery hopper, which is fixed to the flip of the delivery hopper. When the delivery hopper flips outward and opens, the delivery hopper and the baffle together form a dynamic delivery space that is separated from the receiving and storage area. The joints between the mail box door, delivery door, and receiving box door and the box body are all equipped with interlocking anti-theft and waterproof structures.

[0006] Furthermore, the anti-theft and waterproof structure includes a waterproof groove with a U-shaped cross-section disposed inside the door opening on one side of the box, and a first folded edge disposed around the periphery of the mail box door, the receiving box door and the delivery door and extending into the box body; When the door is closed, the first folded edge is embedded inside the waterproof groove.

[0007] Furthermore, the inner wall of the waterproof groove is folded inward at the end away from the box to form a waterproof fold, so that the depth of the waterproof groove on the side closer to the inside of the box is greater than that on the outside. The end of the first fold is folded in the opposite direction towards the box body to form a second fold for strengthening the structural strength and preventing cuts to the hands.

[0008] Furthermore, the delivery hopper includes a bottom plate and an arc-shaped plate; One side of the base plate is fixedly connected to the inside of the delivery door, and the other side is a free end; The arc-shaped plate is connected between the two ends of the base plate and the delivery door. The arc-shaped plate is provided with a limiting straight edge, which is used to limit contact with the box when the delivery door is opened.

[0009] Furthermore, the free end of the base plate is serrated.

[0010] Furthermore, the top of the baffle is an inclined surface, and the bottom is a flat surface, with the inclined surface and the flat surface connected by a micro-arc surface; When the delivery hopper opens to a certain angle along with the delivery door until it reaches the limit position, the free end of the bottom plate abuts against the baffle, causing the delivery hopper to dynamically isolate the receiving box.

[0011] Furthermore, the delivery door is rotatably connected to the box body via a pivot. The pivot includes a spring-loaded structure, which allows the pivot to be pre-contracted before the installation hole is inserted to facilitate the insertion of the delivery door into the door hole, and then automatically pops out after being aligned with the installation hole on the housing to complete the installation.

[0012] Furthermore, the bottom of the waterproof groove, which interlocks with the rotating side of the delivery door, is provided with an inclined surface to form a clearance groove for avoiding the overturning movement of the delivery hopper.

[0013] Furthermore, both the mailbox door and the mail receiving door are equipped with remote-controlled locks, allowing the owner to remotely open the doors or provide a temporary password to open them without having to be physically present at the location.

[0014] (III) Beneficial Effects Compared with the prior art, this utility model provides a waterproof and anti-theft package delivery combination box structure, which has the following beneficial effects: This utility model combines a mail box, a mail receiving box, and a drop hopper. The drop hopper's flipping motion, along with a baffle, creates a dynamically enclosed space for mail delivery while simultaneously isolating the receiving box space, effectively preventing theft through the drop hopper. This multi-purpose box can handle both daily mail receiving and delivery. Furthermore, the box body utilizes a U-shaped waterproof groove and an interlocking door edge structure to form a waterproof barrier, guiding rainwater outwards and ensuring internal dryness, making it suitable for all-weather outdoor use. The mail receiving box features a remote-controlled lock supporting remote opening and temporary password functionality, enabling unattended delivery and collection, effectively protecting home privacy and security. Additionally, this box can be extended to various scenarios such as commercial POS systems and office document delivery. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0018] like Figure 1-13 As shown, an embodiment of this utility model proposes a waterproof and anti-theft parcel delivery combination box structure, comprising: The box 1 includes a mail box 110, a mail box 120 and a delivery hopper 14; each of which is provided with a mail box door 11, a mail box door 12 and a delivery door 13. The mail box 110 is an independent and enclosed mail storage area. The receiving box 120 and the delivery hopper 14 are isolated by a dynamic and relatively enclosed space formed by the delivery hopper 14 during delivery. After the delivery hopper 14 is closed, the receiving box 120 is connected to the receiving box for storage. The box 1 is equipped with a baffle 15 inside the box corresponding to the position of the delivery hopper 14, which is fixed to the flip of the delivery hopper 14; When the delivery hopper 14 is flipped open outwards, the delivery hopper 14 and the baffle 15 together form a dynamic delivery space that is separated from the receiving storage area. The joints between the mail box door 11, the delivery door 13, and the receiving box door 12 and the box body 1 are all equipped with interlocking anti-theft and waterproof structures 16.

[0019] The delivery hopper 14 and baffle 15 at the delivery opening form a dynamic closed space when the delivery door 13 is opened, separating it from the receiving storage area inside the receiving box 120, effectively preventing theft of items from the box through the delivery opening. The serrated structure of the bottom plate 141 of the delivery hopper 14 further increases the difficulty of anti-theft. The remote control locks 2 equipped on the sending box door 11 and receiving box door 12 support remote opening and programmable temporary passwords, enabling couriers to pick up packages unattended. The U-shaped waterproof groove 161 around the door opening 101 of the box body 1 and the first folded edge 162 and the second folded edge 164 around each box door interlock to form multiple waterproof barriers. The waterproof folded edge 163 guides rainwater to drain along the groove, ensuring that the inside of the storage box is dry. This structure is sturdy and anti-theft, suitable for outdoor all-weather use. It can be used not only in the express delivery field, but also in commercial cashier, office document delivery and other multi-purpose scenarios. At the same time, independent installation protects home privacy and security.

[0020] In commercial POS scenarios, the dispatch storage area can serve as a cash safe, with the dynamic enclosed space formed by the drop hopper 14 and the baffle 15 facilitating the safe depositing of cash by clerks. The remote-controlled lock 2 allows authorized personnel to open it. For office document delivery, the receiving storage area can securely store confidential documents, and the waterproof structure ensures that documents remain dry when installed outdoors. In financial document management, the serrated base plate 141 prevents documents from being pulled out from the inside, and the interlocking structure formed by the U-shaped waterproof groove 161 and the first and second folded edges 162 ensures the dry preservation of securities and documents. This versatile design based on the core anti-theft and waterproof structure 16 can meet the needs of various application scenarios requiring secure temporary storage and transfer of items.

[0021] like Figure 1-13 As shown, in some embodiments, the anti-theft and waterproof structure 16 includes a waterproof groove 161 with a U-shaped cross-section disposed inside the door hole 101 on one side of the box body 1, and a first folded edge 162 disposed around the periphery of the mail box door 11, the mail receiving door 12 and the delivery door 13 and extending into the box body 1. When the door is closed, the first folded edge 162 is embedded inside the waterproof groove 161.

[0022] By inserting the first folded edge 162 around the perimeter of the cabinet door into the U-shaped waterproof groove 161 around the door opening 101 of the cabinet body 1, a physical barrier is formed. The core of this barrier is to change the water penetration path by interlocking the folded edge and the groove. When rainwater hits the closed cabinet door, the cooperation between the first folded edge 162 and the U-shaped waterproof groove 161 can effectively prevent most of the rainwater from directly seeping into the interior of the cabinet body 1, providing a basic guarantee for the entire waterproof system.

[0023] like Figure 1-13As shown, in some embodiments, the inner sidewall of the waterproof groove 161 is folded in the opposite direction towards the inside of the box 1 to form a waterproof fold 163, so that the depth of the waterproof groove 161 on the side closer to the inside of the box 1 is greater than that on the outside. The end of the first folded edge 162 is folded in the opposite direction towards the box body 1 to form a second folded edge 164 for strengthening the structural strength and preventing cuts.

[0024] The U-shaped waterproof channel 161, located near the interior of the housing 1, has an inner waterproof folded edge 163 formed by folding the top of the channel wall inward by 180 degrees. This structure artificially creates a height difference within the channel, making the side closer to the outside higher and the side closer to the inside shallower. This achieves active flow guidance and enhanced waterproofing. Even if a small amount of rainwater crosses the first line of defense and enters the U-shaped waterproof channel 161, the shallower inner structure and the waterproof folded edge 163 will force the water to flow along the shallow area of ​​the U-shaped waterproof channel 161 to both sides and eventually discharge it outside the housing 1, rather than continuing to penetrate into the interior of the housing 1. This greatly improves the reliability of waterproofing.

[0025] The waterproof folded edge 163 structure not only achieves active drainage and waterproof enhancement through the height difference design, but also transforms the sharp edges produced by the original cutting of the board into smooth rounded corners through a 180-degree folding process. This ensures that the edges of the waterproof groove 161 that users may come into contact with when operating or cleaning inside the box 1 are free of sharp corners, effectively avoiding the risk of scratches and improving the safety of product use.

[0026] At the end of the first folded edge 162 continuously arranged around the mail box door 11, the mail receiving box door 12 and the delivery door 13, a second folded edge 164 is formed by folding it 180 degrees again, which is closely attached to the first folded edge 162 and continuously distributed. This multi-folding process that is continuously carried out around the box door significantly increases the moment of inertia and structural integrity of the entire box door edge section.

[0027] The continuous second folded edge 164 around the four sides greatly and uniformly enhances the structural rigidity and resistance to torsional deformation of the entire door edge. This continuous reinforcement structure allows the door to be impacted or pried by external forces from different directions, with each side working together to resist local deformation. This not only comprehensively improves the anti-theft performance, but also ensures that the continuous first folded edge 162 around the four sides and the corresponding U-shaped waterproof groove 161 on the body 1 can maintain a long-lasting and tight fit along the entire perimeter of the door frame, thereby maintaining a consistent and long-lasting waterproof and anti-theft effect.

[0028] The second folded edge 164 structure greatly enhances the rigidity of the door edge structure and ensures a durable waterproof effect. At the same time, the second folded edge 164, through a 180-degree folding process, completely wraps the end of the first folded edge 162 on the back of the door, forming a smooth and flat edge. This ensures that when the user manually closes the door or when items inside the box rub against the back of the door, there is no risk of sharp-angle contact, significantly improving safety and user experience during use.

[0029] like Figure 1-13 As shown, in some embodiments, the delivery hopper 14 includes a bottom plate 141 and an arc-shaped plate 142; One side of the base plate 141 is fixedly connected to the inside of the delivery door 13, and the other side is a free end; The arc-shaped plate 142 is connected between the two ends of the base plate 141 and the delivery door 13. The arc-shaped plate 142 is provided with a limiting straight edge 143, which is used to limit contact with the box body 1 when the delivery door 13 is opened.

[0030] The delivery hopper 14 is a semi-enclosed container consisting of a base plate 141 and an arc-shaped plate 142. Its unique arc-shaped plate 142 has a combination of large and small arc segments on its outer edge. The limiting straight edge 143 is used for the transition between the large and small arc segments. When the delivery door 13 is flipped open outward, it can accurately contact the waterproof groove 161 of the box body 1. At this time, the large arc segment of the arc-shaped plate 142 is inside the box body 1, and the small arc segment is outside the box body 1.

[0031] The limiting straight edge 143 precisely controls the final opening angle of the delivery hopper 14, ensuring that it can stay in the preset ideal position each time. This provides a key positional guarantee for the delivery hopper 14 and the internal baffle 15 to form a stable and consistent dynamic closed space.

[0032] like Figure 1-13 As shown, in some embodiments, the free end of the base plate 141 is serrated.

[0033] The bottom plate 141 of the delivery bin 14 is machined into a sawtooth shape at its free end (i.e. the end away from the delivery door 13), which significantly enhances the anti-theft security. When the delivery door 13 is closed, the sawtooth structure can effectively increase the difficulty and resistance of hooking items upward from the receiving storage area by hand or tool through the gap, preventing "fishing" theft and protecting the safety of the items inside the box.

[0034] like Figure 1-13 As shown, in some embodiments, the top of the baffle 15 is an inclined surface 151 and the bottom is a flat surface 152, and the inclined surface 151 and the flat surface 152 are connected by a micro-arc surface 153. When the delivery hopper 14 is opened to a certain angle along with the delivery door 13 until it reaches the limit state, the free end of the bottom plate 141 abuts against the baffle 15, so that the delivery hopper 14 dynamically isolates the receiving box 120.

[0035] The baffle 15 is designed with a composite surface, with an upper inclined surface 151 and a lower flat surface 152, smoothly transitioning through a micro-arc surface 153 in the middle. When the delivery hopper 14 is opened to the correct position, the end of its bottom plate 141 rests precisely against the connection area between the micro-arc surface 153 and the inclined surface 151. This structure ensures that the opened delivery hopper 14 and the fixed baffle 15 fit tightly together, forming a temporary delivery area that is relatively enclosed on the top and sides. This ensures that items can slide in smoothly while effectively preventing direct external access to the main storage area, perfectly balancing delivery convenience and storage anti-theft.

[0036] like Figure 1-13 As shown, in some embodiments, the delivery door 13 is rotatably connected to the box body 1 via a pivot. The pivot includes a spring-loaded structure 17, which allows the pivot to be pre-contracted before the installation hole to facilitate the insertion of the delivery door 13 into the door hole, and to automatically pop out after being aligned with the installation hole 18 on the housing 1 to complete the installation.

[0037] like Figure 1-13 As shown, in some embodiments, the spring-loaded pin structure 17 includes a spring-loaded pin body 171, a pull rod 172, a spring 173, and a spring-loaded pin mounting seat 174 disposed on the first folded edge 162. The spring-loaded pin body 171 is movably sleeved inside the spring-loaded pin mounting seat 174. One end of the spring-loaded pin body 171 extends into the mounting hole 18 on the housing 1, and the other end is fixed to the pull rod 172. The spring 173 is movably sleeved on a section of the pull rod 172 located inside the spring-loaded pin mounting seat 174. The end of the pull rod 172 away from the spring-loaded pin body 171 extends to the outside of the spring-loaded pin mounting seat 174. The pull rod 172 is L-shaped.

[0038] The pivot connecting the delivery door 13 and the housing 1 employs a spring-loaded pin structure 17 with a built-in spring 173. When no force is applied, the spring-loaded pin body 171 of the spring-loaded pin structure 17 extends for positioning. When pressed or pulled by the lever 172, the spring-loaded pin body 171 compresses the spring 173 and retracts into the spring-loaded pin mounting seat 174. This design greatly simplifies the installation process, especially when operating inside the housing 1 where visibility is poor. The installer only needs to press the spring-loaded pin structure 17 or pull the lever 172 to align it with the mounting hole 18, and the spring-loaded pin body 171 will automatically pop out after releasing, thus completing the fixation. This achieves "blind installation," improving production efficiency and the convenience of later maintenance.

[0039] like Figure 1-13As shown, in some embodiments, the bottom of the waterproof groove 161, which is interlocked with the rotating side of the delivery door 13, is provided with a slope 151 to form a clearance groove 165 for avoiding the flipping movement of the delivery hopper 14. The housing 1 is also provided with several fixing holes 19, which are used to fix the housing 1 in a preset position with fasteners.

[0040] At the bottom of the waterproof groove 161 on the side where the rotating shaft of the delivery door 13 is located, a slope 151 is specially machined to form a larger clearance groove 165. At the same time, remote control locks 2 are provided for the dispatch box door 11 and the receiving box door 12; the slope 151 of the clearance groove 165 is designed to provide the necessary movement space for the delivery hopper 14 during the flipping process, avoiding interference between the delivery hopper 14 and the structure of the box body 1, and ensuring smooth operation.

[0041] The mail delivery box can be fixed to the ground or wall, or built into the wall, using fasteners such as screws, bolts, and rivets through the fixing holes 19 inside the box 1 to prevent it from being moved.

[0042] like Figure 1-13 As shown, in some embodiments, both the mail box door 11 and the mail box door 12 are equipped with remote control locks 2.

[0043] One end of the dispatch box door 11 and the collection box door are hinged to the box body 1, and the other side is locked to the box body 1 by a remote control lock 2. The remote control lock 2 is used to open or close the box.

[0044] The remote control lock 2 gives the box 1 intelligent sending and receiving functions, allowing authorized personnel (such as couriers) to open the box remotely after verification, realizing unattended sending and receiving of packages, which greatly improves the convenience of use and application scenarios.

[0045] like Figure 1-13 As shown, in some embodiments, the remote control lock 2 is a programmable temporary password lock. In this configuration, the user or system can generate a one-time, time-limited temporary password and authorize it to the courier. The courier can unlock the lock with the temporary password, which expires immediately afterward. This method not only retains the convenience of remote control but also avoids the risk of leakage of fixed passwords, providing a higher level of security and flexible access control capabilities. It is particularly suitable for scenarios such as short-term rentals and shared office space management.

[0046] like Figure 1-13 As shown, in some embodiments, a handle 131 is provided on the side of the delivery door 13 away from the delivery hopper 14, so that the user can easily pull the delivery door 13 to flip out the delivery hopper 14 by using the handle 131.

[0047] A method for manufacturing a waterproof and theft-proof package delivery combination box includes the following steps: S1. The box body 1 and the door body are formed, and the box body 1, the dispatch box door 11, the receiving box door 12 and the delivery door 13 are respectively manufactured; A corresponding installation door hole 101 is made on the housing 1, and a U-shaped waterproof groove 161 with a waterproof folded edge 163 is processed around each door hole 101 by bending process. The bottom of the waterproof groove 161 corresponding to the rotating side of the delivery door 13 is made into a bevel 151 to form a clearance groove 165. The U-shaped waterproof groove 161 around each installation door hole 101 is formed into a continuous and leak-proof U-shaped ring groove by welding or gluing. S2. Install the delivery hopper 14 assembly, and fix the delivery hopper 14 to the inside of the delivery door 13; The free end of the bottom plate 141 of the delivery hopper 14 is machined into a sawtooth shape;

[0048] S3. Dynamic anti-theft space construction: a baffle 15 is fixedly installed inside the box 1 at the position corresponding to the serrated edge of the delivery hopper 14. Adjust the relative position between the baffle 15 and the open delivery hopper 14 so that the two can form a dynamically enclosed space that is separated from the receiving and storage area below. S4. The delivery door 13 is easy to install. The delivery door 13, which is equipped with the delivery bin 14, is screwed to the box body 1 through a pivot. Among them, the spring pin structure 17 is used as the pivot. By compressing the spring pin structure 17, the delivery door 13 is positioned at the installation position. After the spring pin structure 17 is aligned with the pivot mounting hole 18 on the box 1, it is released and the spring pin structure 17 automatically pops out to complete the fixation. S5. Lock and accessory installation: Install remote control locks 2 on the mail box door 11 and the mail receiving box door 12; and use the fixing holes 19 inside the box 1 to fix the entire box 1 in the preset position.

[0049] In summary, the dynamic enclosed space formed by the delivery hopper 14 and the baffle 15 effectively prevents theft of items from the delivery opening. The serrated bottom plate 141 further enhances the anti-theft performance. The remote control lock 2 supports remote opening and temporary password functions, enabling unattended delivery and receipt. The U-shaped waterproof groove 161, the first folded edge 162, and the second folded edge 164 interlock to form multiple waterproof barriers. The waterproof folded edge 163 guides rainwater outward to ensure internal dryness. This structure is sturdy and durable, suitable for all-weather outdoor use, and can also be extended to commercial cash registers, office document delivery, and other multi-purpose scenarios. At the same time, independent installation effectively protects home privacy and security.
