Description

Technical Field

[0001] The utility model relates to the field of parcel boxes, in particular to an automatic anti-theft parcel box. Background Art

[0002] With the rapid development of the logistics industry, parcel boxes are widely used.

[0003] In traditional solutions, drawer-type parcel boxes are often used. In order to protect the security and privacy of the items delivered in the parcel box, an anti-theft structure is usually set inside the parcel box. For example, an anti-theft postal parcel box disclosed in Chinese Patent CN111436818A has a pull-out single-board anti-theft structure inside, which plays a certain anti-theft role.

[0004] However, the single-board anti-theft structure in the above solution has certain limitations. Considering the different sizes and weights of the parcels delivered in the box body, the bottom plate of the single-board anti-theft structure in this solution may be deformed due to heavier parcels in the long-term application, so the stability of this structure is poor. Moreover, the movement trajectory of the single-board anti-theft structure occupies nearly half of the space inside the parcel box. When there are more items delivered in the parcel box, the anti-theft structure cannot operate normally, and even the parcel box cannot be opened normally. The items delivered in the parcel box will interfere with the opening angle of the parcel box and block the anti-theft effect of the anti-theft structure. Summary of the Utility Model

[0063] Specifically, each slide rail module is composed of a main slide rail 202, a secondary slide rail 203 and a baffle 204. The main slide rail 202 is arranged on the inner side wall of the box body 1 along the length direction of the side wall of the box body 1 (i.e., the width direction of the box body 1), and the main slide rail 202 is installed on the inner side wall of the box body 1 through a mounting plate 205 with a height greater than its own; one side of the secondary slide rail 203 is horizontally and slidably connected to the main slide rail 202, and the baffle 204 is connected to the other side of the secondary slide rail 203 and is arranged parallel to the inner side wall of the box body 1; due to the main slide rail 202 and the secondary slide rail 203 having a certain thickness, there is a certain gap between the baffle 204 and the adjacent mounting plate 205; in order to install the subsequent flipping mechanism, L-shaped extensions 206 extend from the bottoms of the two baffles 204 into the cavity; thus, the drawer mechanism 2 is a drawer structure with a hollow bottom.

[0064] The two-way flipping mechanism 3 is rotatably connected to the hollow part at the bottom of the drawer mechanism 2, and the two-way flipping mechanism 3 serves as a movable bottom plate of the drawer mechanism 2; when the two-way flipping mechanism 3 enters / leaves the delivery opening 101 along with the drawer mechanism 2, it flips downward / upward; when the two-way flipping mechanism 3 flips downward, it plays a role in wrapping and lowering, and when the two-way flipping mechanism 3 flips upward, it can support the package to be delivered and at the same time block the delivered package below the two-way flipping mechanism 3 to achieve anti-theft and anti-privacy leakage;

[0065] Specifically, the two-way flipping mechanism 3 is composed of a limit guide rail 301, a front flip plate 302 and a rear flip plate 303; there are two limit guide rails 301, which are symmetrically arranged with each other; each limit guide rail 301 is installed in the gap between one side baffle 204 and the mounting plate 205 and is located below the slide rail module; the front flip plate 302 is rotatably connected to the bottom of the sliding mechanism 201 near the box door 103, and the rear flip plate 303 is rotatably connected to the bottom of the sliding mechanism 201 far from the box door 103, and the rear flip plate 303 and the front flip plate 302 are arranged corresponding to each other; both sides of the rear flip plate 303 are respectively matched with the two limit guide rails 301 to realize flipping downward / upward when entering / leaving the delivery opening 101 along with the drawer mechanism 2;

[0066] Specifically, the front flap 302 is disposed between the two baffles 204 along the length direction of the front surface of the box body 1 (i.e., the length direction of the box body 1), and both sides of the front flap 302 are respectively rotatably connected to the extension members 206 of the two baffles 204 on both sides thereof through a rotating shaft 304. The front flap 302 can perform a rotating action with the rotating shaft 304 as the central axis;

[0067] Specifically, the rear flap 303 is disposed between the two baffles 204 along the length direction of the rear surface of the box body 1, and the rear flap 303 is disposed away from the front flap 302. Both sides of the rear flap 303 are also respectively rotatably connected to the extension members 206 of the two baffles 204 on both sides thereof through a rotating shaft 304. The rear flap 303 can perform a rotating action with the rotating shaft 304 as the central axis;

[0068] Specifically, each limiting guide rail 301 is connected to the side wall of the mounting plate 205 of the main slide rail 202 adjacent thereto, and each limiting guide rail 301 is disposed at a position between the main slide rail 202 and the bottom of the mounting plate 205 of the main slide rail 202; the front end of each limiting guide rail 301 is disposed along the length direction of the baffle 204 and is lower than the adjacent baffle 204, and the rear end of each limiting guide rail 301 is disposed obliquely upward and is higher than the adjacent baffle 204; the inclined portion of each limiting guide rail 301 is arc-shaped, and the concave surface of the arc portion 305 of each limiting guide rail 301 faces upward; a gap is provided between the bottom of each limiting guide rail 301 and the bottom of the mounting plate 205, and this gap forms a flap track limiting groove 306. Since the inclined portion of the limiting guide rail 301 is arc-shaped, the end space of the flap track limiting groove 306 is larger than its front end space;

[0069] Specifically, a pair of L-shaped connectors 307 parallel to the rear flap 303 are respectively connected to both sides of the end of the lower surface of the rear flap 303 close to the limiting guide rail 301; the two L-shaped connectors 307 are arranged corresponding to the flap track limiting grooves 306 on both sides, and the lower ends of the two L-shaped connectors 307 are respectively connected to both sides of the lower surface of the rear flap 303, and pulleys 308 are respectively connected to the upper ends of the two L-shaped connectors 307, and the pulleys 308 of the two L-shaped connectors 307 are respectively arranged in the flap track limiting grooves 306 on both sides of the rear flap 303, and the two pulleys 308 slide along the bottom of the two limiting guide rails 301;

[0070] Optionally, a front stop bar 309 is vertically provided at one end of the bottom hollow part of the pulling mechanism 2 close to the box door 103, and 310 is vertically provided at the end of the bottom hollow part of the pulling mechanism 2 away from the box door 103.

[0071] Optionally, an L-shaped female supporting member 311 is connected to the end of the rear flap 303 away from the limit guide rail 301 along the length direction of the rear flap 303, and an L-shaped male supporting member 312 is connected to the end of the front flap 302 away from the limit guide rail 301 along the length direction of the front flap 302. When the rear flap 303 and the front flap 302 are both turned upward to form a plane, the upper surface of the L-shaped female supporting member 311 and the lower surface of the L-shaped male supporting member 312 can come into contact with each other, achieving a certain supporting effect and improving the supporting stability of the rear flap 303 and the front flap 302 in the horizontal state.

[0072] Optionally, a number of irregular through holes 313 are respectively formed in the front flap 302 and the rear flap 303. The through holes 313 are beneficial to increasing the toughness and supporting strength of the front flap 302 and the rear flap 303, and at the same time, it is also convenient for the deliverer to know the capacity of the cavity of the parcel box when delivering parcels.

[0073] As an implementation manner of the present utility model, the working principle of the present utility model is as follows:

[0074] (1) When the pulling mechanism 2 is not pulled out of the delivery port 101:

[0075] The pulley 308 of the L-shaped connecting member 307 of the rear flap 303 is located at the end of the flap track limiting groove 306. At this time, the pulley 308 extends beyond the horizontal part of the limit guide rail 301. At this time, the L-shaped connecting member 307 is in a vertical state and does not play a limiting role on the rear flap 303. Under the action of the rotating shaft 304 connected to itself, both the rear flap 303 and the front flap 302 are in a downward turning state;

[0076] (2) When the pulling mechanism 2 is pulled out of the delivery port 101:

[0077] The pulley 308 of the L-shaped connecting member 307 of the rear flap 303 slides along the limit guide rail 301, and the pulley 308 gradually enters the horizontal part of the flap track limit groove 306 along the limit guide rail 301. At this time, driven by the L-shaped connecting member 307, the rear flap 303 is gradually lifted to the horizontal state. At the same time, during the process of the drawing mechanism 2 pulling out the delivery port 101, the front flap 302 is blocked by the delivery port 101 and will also be gradually lifted to the horizontal state. In the above process, since the front flap 302 first touches the edge of the delivery port 101, the front flap 302 flips first, and then the rear flap 303 flips. The lower surface of the L-shaped sub-supporting member 312 of the front flap 302 is supported by the upper surface of the L-shaped mother supporting member 311 of the rear flap 303 to realize the supporting effect between the flaps. At this time, the two flaps become a storage board for placing the items to be delivered, and block and protect the delivered items below. The deliverer can place the items to be delivered on this storage board. The above process is synchronous, that is, as the drawing mechanism 2 moves outside the delivery port 101 until it cannot move, the front flap 302 flips upward first and is accompanied by the upward flipping of the rear flap 303, and the two support each other to form a storage board.

[0078] (3) After delivery:

[0079] Push the drawing mechanism 2. Under the action of the slide rail module, the drawing mechanism 2 moves into the delivery port 101. At this time, the pulley 308 of the L-shaped connecting member 307 of the rear flap 303 slides along the limit guide rail 301, and the pulley 308 gradually enters the end part of the flap track limit groove 306 along the limit guide rail 301. The front flap 302 does not change its shape under the block of the edge of the delivery port 101. Until the pulley 308 of the L-shaped connecting member 307 of the rear flap 303 exceeds the horizontal part of the limit guide rail 301, the pulley 308 is located at the end of the flap track limit groove 306. At this time, the L-shaped connecting member 307 is in a vertical state and does not play a limiting role on the rear flap 303. The rear flap 303 becomes a downward flipping state under the action of its own connected rotating shaft 304. At the same time, the front flap 302 has completely entered the box body 1 and is not interfered by the edge of the delivery port 101. Under the action of its own connected rotating shaft 304, it also becomes a downward flipping state. The above process is synchronous, that is, as the drawing mechanism 2 enters the delivery port 101 until it cannot move, the rear flap 303 flips downward first and is accompanied by the downward flipping of the front flap 302, so that the delivered items on it fall into the cavity of the box body 1 to complete a delivery.

[0080] The above is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure made by using the description and drawings of the present invention, or directly or indirectly applied to other related technical fields, is equally included in the patent protection scope of the present invention.
