[0039] To make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0040] The present invention provides a foldable turnover box for logistics transfer and distribution, which replaces the turnover box used in traditional logistics transfer and distribution, avoiding the problem that the turnover box cannot be sterilized after sealing, which easily causes the internal objects to be damaged due to bacterial growth during transportation.

[0041] Figures 1-9 The diagram shows the structure of a foldable turnover box for logistics transfer and distribution of the present invention. Figures 1-9A detailed introduction is given to this type of foldable turnover box for logistics transfer and distribution.

[0042] Example 1

[0043] refer to Figures 1-9 The present invention discloses a foldable turnover box for logistics transfer and distribution, the main body of which includes a box body 100, a vacuum mechanism 200 and a sterilization mechanism 300.

[0044] refer to Figure 1-Figure 4 The box body 100 is used to carry objects to be transferred. The box body 100 includes a box body 110 with an open top and a box cover 120 rotatably mounted on the top opening of the box body 110. The box body 100 is used to contain the objects to be transferred. The box cover 120 is used to seal the top opening of the box body 110. The box body 110 has a first state for packing objects and a second state for folding. When not in use, the box body 110 can be folded to reduce the space it occupies.

[0045] refer to Figure 1-Figure 5 The vacuuming mechanism 200 is used to extract air from the box body 110 after the box lid 120 is closed to seal the box. The vacuuming mechanism 200 includes a ventilator 210 installed on the box body 110 and having a fan therein, and a transmission assembly 220 which is transmission-connected at one end to the fan inside the ventilator 210 and at the other end to the box lid 120. The fan inside the ventilator 210 is used to extract air from the box body 110 when it rotates, thereby reducing the speed at which bacteria and spoilage of items inside the box body 110 are grown. The transmission assembly 220 is used to drive the fan to rotate after the box lid 120 is closed, wherein after the box lid 120 is rotated to seal the top opening of the box body 110, the transmission assembly 220 drives the fan inside the ventilator 210 to rotate, so that after the box is sealed, the fan automatically starts to rotate to extract air from the box body 110.

[0046] In this embodiment, a one-way valve is provided on the side wall of the ventilation tube 210 to prevent external air from entering the interior of the box body 110 through the ventilation tube 210;

[0047] refer to Figure 1-Figure 4The sterilization mechanism 300 is used to automatically irradiate the inside of the box body 110 with blue light when the fan rotates to vacuum the inside of the box body 110, thereby sterilizing the air and articles inside the box body 110. The sterilization mechanism 300 is installed on the box cover 120 and is connected to the fan in the ventilation tube 210. When the fan in the ventilation tube 210 rotates, the sterilization mechanism 300 is automatically driven to start working and irradiate the objects inside the box body 110 with blue light. When the fan inside the ventilation tube 210 stops rotating, the sterilization mechanism 300 stops working. When the fan rotates to vacuum the inside of the box body 110, the sterilization mechanism 300 is driven to start working and irradiate the inside of the box body 110 with blue light, thereby sterilizing the air and articles inside the box body 110, thereby reducing the speed at which bacteria grow and the articles inside the box body 110 become corrupt.

[0048] In this embodiment, the specific usage process is as follows: the items to be transferred are loaded into the box body 110 through the opening at the top of the box body 110. After loading is completed, the box cover 120 is closed to complete the box sealing. At the same time, the transmission component 220 drives the fan inside the ventilation duct 210 to rotate, thereby vacuuming the inside of the box body 110. While vacuuming, the sterilization mechanism 300 starts working and irradiates the inside of the box body 110 with blue light, thereby sterilizing the inside of the box body 110. After vacuuming and blue light irradiation, the speed at which bacteria and corruption of items inside the box body 110 are slowed down.

[0049] Example 2

[0050] Based on Example 1, Figure 3-Figure 4 The box body 110 includes a bottom panel 110a, a top panel 110b, and side panels 110c located around the bottom panel 110a and the top panel 110b. The bottom panel 110a, the top panel 110b, and the side panels 110c cooperate to form a complete box. The side panels 110c are grouped in pairs, and the adjacent sides of the two side panels 110c in the same group are hinged. The other two ends of the two side panels 110c in the same group are hinged to the side walls of the bottom panel 110a and the top panel 110b, respectively. Therefore, when not in use, the side panels 110c can be folded by pressing the top panel 110b, thereby saving the space they occupy.

[0051] In this embodiment, reference Figure 4 The side wall of the side panel 110c is provided with a slot 110c-1, and a pin is inserted into the slot 110c-1. When the box is packed and used, the pin is inserted into the slot 110c-1 to fix the entire box body 110 to prevent it from automatically folding under the action of its own gravity, causing the box body 100 to be unstable. Similarly, when it is not used after transportation is completed, the pin is unplugged to complete the folding of the side panel 110c.

[0057] The side wall of the box cover 120 is provided with a connecting block 120a located in the connecting groove 110b-2, which is used to be fixedly connected to the connecting shaft 110b-21, thereby being rotatably connected to the top plate 110b. The connecting block 120a is fixedly sleeved on the connecting shaft 110b-21 and is used to drive the connecting shaft 110b-21 to rotate when the box cover 120 is rotated;

[0058] refer to Figure 2-Figure 8The transmission assembly 220 includes a bevel gear set 220a located in the receiving groove 110b-3 and connected to the side wall of the connecting shaft 110b-21 at one end by a rotating shaft, a first differential 220a-1 provided at the other end, a second differential 220b that is transmission-connected to the fan inside the ventilator 210 and drives the fan to rotate when rotating, and a driving member 220c that is transmission-connected to the first differential 220a-1 at one end and to the second differential 220b at the other end. The bevel gear set 220a is used to drive the first differential 220a-1 to rotate when rotating, and the first differential 220a-1 is used to drive the spring wheel 220c-2 to rotate when rotating, and increase the transmission. The speed of the pulley 220c-2, the second differential 220b is used to drive the second pulley 220b-1 to rotate when it rotates, and increase its speed, the driving member 220c is used to tighten the driving member 220c when the first differential 220a-1 rotates and drives it to work, when the first differential 220a-1 stops rotating, the driving member 220c drives the second differential 220b to rotate, wherein, after the first differential 220a-1 rotates to drive the driving member 220c to work, it automatically drives the second differential 220b to rotate, and is used to drive the fan to rotate for exhaust through the rotation of the second differential 220b after the box cover 120 is closed.

[0059] In this embodiment, reference Figure 5 The fan side wall inside the ventilator 210 is connected to a first pulley 210a via a rotating shaft, which is used to drive the fan to rotate when rotating;

[0060] refer to Figure 5 The side wall of the second differential 220b is provided with a second pulley 220b-1 connected to the first pulley 210a through a pulley, which is used to drive the first pulley 210a to rotate when the second differential 220b rotates and drives it to rotate;

[0061] refer to Figure 5-Figure 8The driving member 220c includes a box body 220c-1 with an arc-shaped groove 220c-11 on the inner wall, a spring wheel 220c-2 located in the box body 220c-1 and connected to the first differential 220a-1 on one side through a rotating shaft, and having a first gear 220c-21 on the other side, a second gear 220c-3 installed in the box body 220c-1 and connected to the end of the second differential 220b away from the second pulley 220b-1 on the side wall through a rotating shaft, and a bottom extending into the arc-shaped groove 220c-11 and connected to the first gear 220 The gear assembly 220c-4 is always engaged with the gear assembly 220c-21, and the spring wheel 220c-2 is used to drive the first gear 220c-21 to rotate and tighten when the case cover 120 and the first differential 220a-1 rotate. The first gear 220c-21 is used to drive the gear assembly 220c-4 to rotate when it rotates, and the second gear 220c-3 is used to drive the second differential 220b to rotate when it rotates. The gear assembly 220c-4 is used to drive the spring wheel 220c-21 to rotate when the first differential 220a-1 rotates. 2 is separated from the second gear 220c-3 when it is rotated. When the first differential 220a-1 stops driving the spring wheel 220c-2 to rotate, the spring wheel 220c-2 reverses, and the first gear 220c-21 reverses to drive it to rotate, and then drives the second gear 220c-3 to rotate. When the first differential 220a-1 rotates and drives the spring wheel 220c-2 to rotate, the second gear 220c-3 is separated from the gear assembly 220c-4, thereby maintaining the second differential 220b and The fan does not rotate. When the first differential 220a-1 stops rotating and the clockwork wheel 220c-2 starts to reverse, the driving gear assembly 220c-4 moves along the arc-shaped groove 220c-11 and engages with the second gear 220c-3. Then, after the box cover 120 is closed, the clockwork wheel 220c-2 reverses and drives the gear assembly 220c-4 to move to a position engaged with the second gear 220c-3 and drives the second gear 220c-3 to rotate, thereby driving the second differential 220b and the fan to rotate, thereby starting vacuuming.

[0062] In this embodiment, reference Figure 5-Figure 8The gear assembly 220c-4 includes a third gear 220c-41 meshing with the first gear 220c-21 and a fourth gear 220c-42 located at the bottom of the third gear 220c-41 and extending into the arc-shaped slot 220c-11. The third gear 220c-41 is used to drive the fourth gear 220c-42 to rotate when it rotates. The fourth gear 220c-42 is used to drive the second gear 220c-3 to rotate when it is meshed with the second gear 220c-3. When the first differential 220a-1 rotates, it drives the mainspring. When the wheel 220c-2 rotates, the second gear 220c-3 is separated from the fourth gear 220c-42. When the first differential 220a-1 stops rotating and the spring wheel 220c-2 starts to reverse, the fourth gear 220c-42 is driven to move along the arc groove 220c-11 and then mesh with the second gear 220c-3. Then, when the box cover 120 is closed to seal the box, the connecting shaft 110b-21 rotates to drive the bevel gear set 220a to rotate, which drives the first differential 220a-1 to rotate, and then drives the spring wheel 220c-2 to rotate. When the box cover 120 is closed, the spring wheel 220c-2 is reversed, driving the first gear 220c-21 to reverse. At this time, in the process of driving the third gear 220c-41 and the fourth gear 220c-42 to rotate, the fourth gear 220c-42 moves along the arc groove 220c-11 to a position meshing with the second gear 220c-3, thereby driving the fourth gear 220c-42 to rotate. After the second gear 220c-3 is driven to rotate, the second gear 220c-3 drives the second differential 220b to rotate when it rotates. After the second differential 220b rotates, it drives the fan to rotate through the second pulley 220b-1 and the first pulley 210a, thereby vacuuming the inside of the box body 110. When the spring wheel 220c-2 reverses for a certain period of time and stops rotating, it indirectly drives the fan to stop rotating, completing the vacuum operation. At this time, the inside of the box body 100 is in a vacuum or semi-vacuum state, thereby slowing down the growth of bacteria and the rate of corruption of the items.

[0063] In this embodiment, a connecting member (not shown in the figure) is connected to the rotating shaft between the bevel gear set 220a and the first differential 220a-1, and the connecting member includes a ratchet connecting seat with a ratchet groove on the side wall and a ratchet located in the ratchet groove and with a plurality of elastic pawls on the side wall, which is used to prevent the mainspring wheel 220c-2 from reversing and driving the first differential 220a-1 to reverse, thereby driving the bevel gear set 220a to reverse, and then generating a force to drive the connecting shaft 110b-21 and the box cover 120 to reverse. When the box cover 120 receives the limiting engagement action of the card slot 110b-4 and the elastic card block 120b, the entire transmission assembly 220 is stuck and the vacuum operation cannot be completed.

[0064] Example 4

The blue light sterilization lamp 310 is used to irradiate the interior of the box body 110 with blue light when turned on, thereby sterilizing the interior of the box body 110. The trigger switch 310a is used to control the switch of the blue light sterilization lamp 310. The trigger assembly 320 is used to contact the trigger switch 310a when the fan rotates and separate from the trigger switch 310a when the fan stops rotating. When the fan inside 10 rotates, it automatically drives the trigger component 320 to contact the trigger switch 310a, and when the fan inside the ventilator 210 stops rotating, the trigger component 320 is automatically separated from the trigger switch 310a, and then when the fan rotates to vacuum, the trigger component 320 works to contact the trigger switch 310a, so that the blue light sterilization lamp 310 is turned on and the inside of the box body 110 is sterilized by blue light irradiation. When the fan stops rotating and the vacuum operation is completed, the trigger component 320 is separated from the trigger switch 310a, so that the blue light sterilization lamp 310 is turned off, completing the blue light irradiation sterilization work of the inside of the box body 110.

[0066] In this embodiment, reference Figures 1-9The trigger assembly 320 includes a threaded cylinder 320a installed at the bottom of the top plate 110b through a fixing frame and having a third pulley 320a-1 at the bottom, and a threaded rod 320b located in the threaded cylinder 320a and having a limiting slider 320b-1 on the side wall at one end. The threaded cylinder 320a is used to drive the threaded rod 320b to telescopically move under the limiting action of the limiting slide groove 320a-2 and the limiting slider 320b-1 when it rotates. The third pulley 320a-1 is used to drive the threaded cylinder 320a to rotate when the first pulley 210a rotates and drives it to rotate. The threaded rod 320b is used to extend the threaded cylinder 320a and then contact the trigger switch 310a, thereby turning on the blue light sterilization lamp 310. The inner wall of the threaded barrel 320a has a limiting groove 320a-2 adapted to the limiting slider 320b-1, which is used to cooperate with the limiting slider 320b-1 so that when the threaded barrel 320a rotates, the threaded rod 320b is driven to move telescopically. The inner wall of the threaded barrel 320a is provided with an elastic member 320a-3 connected to the bottom of the threaded rod 320b at the other end, which is used to generate a reaction force when the threaded rod 320b is extended, so that after the fan and the threaded barrel 320a stop rotating, the reaction force of the elastic member 320a-3 drives the threaded barrel 320a to reverse and automatically retract the threaded rod 320b into the threaded barrel 320a, wherein the threaded rod 320b can contact the trigger switch 310a.

[0067] In this embodiment, a connecting piece (not shown in the figure) is provided on the rotating shaft between the threaded barrel 320a and the third pulley 320a-1, which is used to prevent the fan and the entire transmission assembly 220 from being stuck after generating a reverse force when the threaded barrel 320a is reversed to retract the threaded rod 320b, resulting in the threaded barrel 320a being unable to reverse and the threaded rod 320b being unable to be retracted, thereby causing the blue light sterilization lamp 310 to always be in the on state, increasing energy consumption.

[0068] Although the present invention has been described above with reference to embodiments, various modifications may be made thereto and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as there are no structural conflicts, the various features of the embodiments disclosed herein may be combined with each other in any manner, and the omission of an exhaustive description of such combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
