Description

Technical Field

[0001] The present invention belongs to the technical field of packaging boxes, and particularly relates to a door lock packaging box. Background Art

[0002] Currently, the packaging boxes of smart door locks on the market are usually made of foam plastics such as polystyrene boards (EPS) and polyethylene foam (EPE). The smart door lock includes an inner lock body installed inside the door and an outer lock body installed outside the door. Since electronic components are built into the smart door lock, during the handling process, in order to avoid damage to the door lock caused by the collision between the inner lock body and the outer lock body, separate transportation or simultaneous transportation using a larger packaging box is required. Moreover, a large amount of foam cushioning materials need to be filled in the packaging box, resulting in an increase in the volume of the packaging box and difficult handling, which not only increases the cost of the packaging box, but also leads to corresponding increases in transportation and storage costs.

[0003] In addition, the plastic door lock packaging box is not conducive to recycling, and is prone to problems such as waste of resources and environmental pollution.

In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0042] The technical solution of the present invention will be further described below in conjunction with the drawings and through specific embodiments.

[0043] Existing intelligent door locks include an inner lock body installed inside the door and an outer lock body installed outside the door. Since electronic components are built into the intelligent door lock, during the handling process, in order to avoid damage to the door lock caused by the collision between the inner lock body and the outer lock body, it is necessary to transport them separately or use a larger packaging box for simultaneous transportation. Moreover, a large amount of foam cushioning materials need to be filled in the packaging box, resulting in difficult handling and correspondingly increased transportation and storage costs.

[0044] In addition, the packaging boxes of intelligent door locks on the market are usually made of foam plastics such as polystyrene board (EPS) and expanded polyethylene (EPE), which have high manufacturing costs, are not conducive to recycling, and are prone to problems such as resource waste and environmental pollution.

[0045] To solve the above problems, as Figure 1 and Figure 2 shown, this embodiment discloses a door lock packaging box, which is used to accommodate the door lock and facilitate the safe transportation of the door lock. Of course, this door lock packaging box can also be used for the packaging and transportation of other products, such as handicrafts, toys, and electronic products, etc.

[0046] The door lock packaging box of this embodiment is folded from paper materials. Compared with the packaging box made of plastic materials, this door lock packaging box has a simple structure, low cost, is convenient for recycling and reuse, and is green and environmentally friendly. Moreover, before the door lock packaging box is formed, it can be transported flat, saving transportation costs.

[0047] As Figure 1 shown, the door lock packaging box of this embodiment includes an outer box 1, two first inner cards 2 and a second inner card 3. Specifically, the outer box 1 is a paper box body that can be opened or closed. The outer box 1 can be integrally formed by folding a paper card, with a simple structure and easy operation. Or it can be formed by bonding or other means to improve the connection strength of the outer box 1.

[0048] The outer box 1 of this embodiment is a cubic shell, specifically including a box body and a swing lid. Among them, rectangular openings on the four sides of the box body respectively extend outward with a first swing lid 11, a second swing lid 12, a third swing lid 13 and a fourth swing lid 14. The first swing lid 11 and the third swing lid 13 are distributed oppositely, and the second swing lid 12 and the fourth swing lid 14 are distributed oppositely. When the door lock packaging box needs to be closed, the second swing lid 12 and the fourth swing lid 14 are respectively folded inward by 90° towards the inside of the door lock packaging box to form a buffer layer at the top of the door lock packaging box, so that the top of the door lock packaging box has a good buffering effect. Then the third swing lid 13 is folded inward by 90° towards the inside of the door lock packaging box. Finally, the first swing lid 11 is folded inward by 90° towards the inside of the door lock packaging box to block the open end of the box body.

[0049] Furthermore, a third tongue 112 extends outward from the first swing lid 11, and there is a jack 132 between the third swing lid 13 and the side wall of the box body. When the first swing lid 11 is folded inward by 90° towards the inside of the door lock packaging box, the third tongue 112 is inserted into the jack 132 to realize the locking and fixing of the four swing lids. It should be noted that a first finger hole 111 is opened on the first swing lid 11, and a second finger hole 131 is correspondingly opened on the third swing lid 13. Both the first finger hole 111 and the second finger hole 131 are through holes. When the first swing lid 11 and the third swing lid 13 block the open end of the box body, the first finger hole 111 and the second finger hole 131 are arranged opposite to each other and communicate with the inner cavity of the outer box 1, which is convenient for the handling personnel or users to insert their fingers into the first finger hole 111 and the second finger hole 131 in sequence, facilitating the taking and placing operation of the outer box 1.

[0050] Continuing as Figure 1 shown, both the first inner card 2 and the second inner card 3 of this embodiment are flat cubic box bodies, respectively integrally formed by folding a paper card, with a simple structure and low manufacturing cost. Among them, the two first inner cards 2 are arranged relatively at intervals, and the inner lock body and the outer lock body of the door lock are fixedly installed between the two first inner cards 2. The number of the second inner cards 3 is one, which is mainly used to accommodate the accessories of the door lock, such as components like batteries and locking screws installed in the door lock. The same outer box 1 can integrally package and transport the inner lock body, the outer lock body and the accessories of the door lock, improving the transportation efficiency of the door lock packaging box.

[0051] It should be noted that the second inner card 3 is selectively arranged on the inner side wall or the inner bottom wall of the outer box 1. For example, as Figure 1As shown, when the length of the intelligent door lock is small, the second inner card 3 can be placed on the inner side wall of the outer box 1 to reduce the length of the internal space of the outer box 1, achieve the compact installation of the door lock, and make full use of the internal space of the outer box 1. When the length of the door lock is long, the second inner card 3 can be placed on the inner bottom wall of the outer box 1. At the same time, the first inner card 2 can form a buffer layer at the bottom of the outer box 1, improve the shock absorption and buffering effect of the door lock packaging box, and is beneficial to protecting the safety of the door lock. Through the flexible installation of the second inner card 3, the internal space of the outer box 1 can be adjusted according to the installation requirements of the door lock, so that the door lock packaging box can package door locks of different lengths or types, improving the space utilization rate and application range of the door lock packaging box.

[0052] Continue as Figure 1 and Figure 2 As shown, the first inner card 2 has two first card slots 210 and second card slots 220 that are staggeredly distributed along the first direction. The two first inner cards 2 are arranged oppositely and are respectively inserted into the corresponding side walls inside the outer box 1. The two ends of one of the inner lock body and the outer lock body are respectively inserted and fixed into the two first card slots 210, and the two ends of the other of the inner lock body and the outer lock body are respectively inserted and fixed into the two second card slots 220. The above-mentioned first direction is the length direction of the vertically placed first inner card 2, that is, the height direction of the outer box 1.

[0053] In this embodiment, the two first inner cards 2 are arranged oppositely, so that one of the inner lock body and the outer lock body is inserted and matched with the two first card slots 210, and the other of the inner lock body and the outer lock body is inserted and matched with the two second card slots 220. Since the first card slots 210 and the second card slots 220 are staggeredly distributed, it avoids the collision of the inner lock body and the outer lock body during transportation and realizes the safe transportation of the door lock. At the same time, the inner lock body and the outer lock body are staggeredly installed, which not only avoids the interference between the inner lock body and the outer lock body, but also is beneficial to the compact installation of the inner lock body and the outer lock body, improving the space utilization rate of the door lock packaging box.

[0054] As Figure 2 and Figure 3 As shown, in the plane expansion diagram of the first inner card 2, the first inner card 2 includes a bottom plate 20. One side edge of the bottom plate 20 extends outward to form a first side plate 21 and a first top plate 231 that are connected in sequence. The other side edge of the bottom plate 20 extends outward to form a second side plate 22 and a second top plate 232 that are connected in sequence. The first side plate 21 and the second side plate 22 are respectively folded upward to form two opposite side walls on the first inner card 2. The first top plate 231 and the second top plate 232 are respectively folded toward the inside of the first inner card 2 and jointly form the top wall of the first inner card 2. The openings of the first card slots 210 and the second card slots 220 are both located on the top wall.

[0055] In order to improve the buffering effect of the first inner card 2, there are a plurality of buffer cavities respectively between the first top plate 231 and the bottom plate 20 and between the second top plate 232 and the bottom plate 20. The buffer cavities are all integrally formed by folding cardboard, with a simple structure and being convenient for processing and manufacturing.

[0056] Specifically, first folding plates 26 and second folding plates 27 extend outward from the side edges of the first top plate 231. The first folding plates 26 and the second folding plates 27 can respectively be folded to form a first buffer cavity and a second buffer cavity arranged in a stepped manner along a first direction. The first folding plates 26 and the second folding plates 27 are separately arranged and are integrally connected to different parts of the side edges of the first top plate 231 respectively, such that the first buffer cavity and the second buffer cavity are arranged in a stepped structure along the first direction. Third folding plates 28 and fourth folding plates 29 extend outward from the side edges of the second top plate 232. The third folding plates 28 and the fourth folding plates 29 can respectively be folded to form a third buffer cavity and a fourth buffer cavity arranged in a stepped manner along the first direction. The third folding plates 28 and the fourth folding plates 29 are separately arranged and are integrally connected to different parts of the side edges on the second top plate 232 respectively, such that the third buffer cavity and the fourth buffer cavity are arranged in a stepped structure along the first direction.

[0057] There is a first indentation line between the first top plate 231 and the first folding plates 26 of this embodiment, and there is a second indentation line between the first top plate 231 and the second folding plates 27, and the first indentation line and the second indentation line are not collinear. There is a third indentation line between the second top plate 232 and the third folding plates 28, and there is a fourth indentation line between the second top plate 232 and the fourth folding plates 29, and the third indentation line and the fourth indentation line are not collinear. The length of the first indentation line is greater than the length of the second indentation line, and the length of the third indentation line is greater than the length of the fourth indentation line. At the same time, the length of the first indentation line is equal to the length of the fourth indentation line, and the length of the second indentation line is equal to the length of the third indentation line. Such that both the first top plate 231 and the second top plate 232 are L-shaped plates and respectively have two stepped indentation lines. The first top plate 231 and the second top plate 232 are symmetrically distributed about the center of the bottom plate 20.

[0058] As Figure 2 shown, the first buffer cavity and the third buffer cavity are folded towards the bottom plate 20 and a first card slot 210 is formed between them, and the second buffer cavity and the fourth buffer cavity are folded towards the bottom plate 20 and a second card slot 220 is formed between them. And at least part of the side walls of the first buffer cavity and the side walls of the second buffer cavity are abutted together, such that the first card slot 210 and the second card slot 220 are isolated from each other, avoiding the first card slot 210 and the second card slot 220 from being communicated under the action of the gravity or other external forces of the inner lock body or the outer lock body, resulting in contact or collision between the inner lock body and the outer lock body, and improving the safe transportation and storage of the door lock.

[0059] For the convenience of understanding, the detailed folding process of the first inner card 2 will now be described in combination with Figures 3 - 7 to illustrate.

[0060] As Figure 3 and Figure 4 shown, the first folding plate 26 includes a first plate 261, a second plate 262, and a third plate 263 that are connected in sequence. The side of the first top plate 231 is connected to the first plate 261. The second folding plate 27 includes a fourth plate 271, a fifth plate 272, and a sixth plate 273 that are connected in sequence. The side of the first top plate 231 is connected to the fourth plate 271. A plurality of first buffer plates 264 that are connected in sequence extend outward from the side of the third plate 263. The plurality of first buffer plates 264 are stacked and folded to form the top wall of the first buffer cavity. A plurality of second buffer plates 274 that are connected in sequence extend outward from the side of the sixth plate 273. The plurality of second buffer plates 274 are stacked and folded to form the bottom wall of the second buffer cavity.

[0061] As Figure 4 shown, the third plate 263 is turned up 90° towards the bottom plate 20, and the second plate 262 is turned down 90° in the opposite direction, so that the third plate 263 and the second plate 262 are stacked together, and the third plate 263 is vertically abutted against the first plate 261. At this time, the first plate 261, the third plate 263, and the plurality of first buffer plates 264 enclose the cavity of the first buffer cavity. Similarly, the sixth plate 273 is turned up 90° towards the bottom plate 20, and the fifth plate 272 is turned down 90° in the opposite direction, so that the sixth plate 273 and the fifth plate 272 are stacked together, and the sixth plate 273 is vertically abutted against the fourth plate 271. At this time, the fourth plate 271, the sixth plate 273, and the plurality of second buffer plates 274 enclose the cavity of the first buffer cavity.

[0062] At this time, since the third plate 263 and the second plate 262 are stacked together, and the sixth plate 273 and the fifth plate 272 are stacked together, the thickness of the third plate 263 and the sixth plate 273 is enhanced, preventing the inner lock body and the outer lock body from piercing through the third plate 263 and the sixth plate 273, and improving the structural strength of the first inner clip 2.

[0063] As Figure 5 shown, continue to turn the first plate 261, the third plate 263, and the plurality of first buffer plates 264 towards the bottom plate 20 by 90° continuously twice, so that the first plate 261 is folded to form the side wall of the first buffer cavity, the third plate 263 is folded towards the second plate 262 to form the bottom wall of the first buffer cavity, and form the bottom wall of the first card slot 210, and the second plate 262 is vertically connected to the third plate 263. Continue to turn the fourth plate 271, the sixth plate 273, and the plurality of second buffer plates 274 towards the bottom plate 20 by 90° continuously twice, so that the fourth plate 271 is folded to form the side wall of the second buffer cavity, the sixth plate 273 is folded towards the fifth plate 272 to form the bottom wall of the second buffer cavity, and form the bottom wall of the second card slot 220, and the fifth plate 272 is vertically connected to the sixth plate 273. Through the above folding process, the folding and forming of the first buffer cavity and the second buffer cavity are completed.

[0064] As Figure 6 shown, the third folding plate 28 includes a seventh plate 281 and an eighth plate 282. The side of the second top plate 232 is connected to the seventh plate 281. The seventh plate 281 is folded to form the side wall of the third buffer cavity, and the eighth plate 282 is folded to form the bottom wall of the third buffer cavity. The fourth folding plate 29 includes a ninth plate 291 and a tenth plate 292. The side of the second top plate 232 is connected to the ninth plate 291. The ninth plate 291 is folded to form the side wall of the fourth buffer cavity, and the tenth plate 292 is folded to form the bottom wall of the fourth buffer cavity. Through this step, the folding and forming of the third buffer cavity and the fourth buffer cavity are completed. At this time, the first buffer cavity and the third buffer cavity, and the second buffer cavity and the fourth buffer cavity are respectively located on both sides of the bottom plate 20 and are oppositely arranged.

[0065] Compared with the first folding plate 26 and the second folding plate 27, the third folding plate 28 and the fourth folding plate 29 in this embodiment are shorter in length, which is beneficial to reducing the consumption of materials and lowering the cost of the door lock packaging box. At the same time, the folding process and steps of the third folding plate 28 and the fourth folding plate 29 are reduced, which is beneficial to improving the production efficiency of the door lock packaging box.

[0066] As Figure 7 shown, after the first buffer cavity and the second buffer cavity are folded 90° towards the bottom plate 20, the third buffer cavity and the fourth buffer cavity continue to be folded 90° towards the bottom plate 20. It should be noted that the widths of the third plate 263 and the sixth plate 273 are equal to the width of the bottom plate 20, so that the third buffer cavity presses against the third plate 263, and the fourth buffer cavity presses against the sixth plate 273, that is, the eighth plate 282 presses against the third plate 263, and the tenth plate 292 presses against the sixth plate 273.

[0067] It should be noted that at this time, the first plate 261 of the first buffer cavity is in contact connection with the ninth plate 291 of the fourth buffer cavity, so as to isolate the first card slot 210 from the second card slot 220 and prevent the two from communicating.

[0068] To ensure that the first buffer cavity, the second buffer cavity, the third buffer cavity, and the fourth buffer cavity are stably attached to the bottom plate 20, as Figure 6 shown, a first locking portion 2631 is provided on the third plate 263, a second locking portion 2731 is provided on the sixth plate 273, a third locking portion 2911 is provided on the ninth plate 291, and a corresponding fourth locking portion 201 is provided on the bottom plate 20. The first locking portion 2631, the second locking portion 2731, and the third locking portion 2911 are respectively installed in cooperation with the corresponding fourth locking portion 201.

[0069] Specifically, the first locking portion 2631, the second locking portion 2731, and the third locking portion 2911 in this embodiment are all die-cut holes from which the cut-off material is removed, and the fourth locking portion 201 is a die-cut hole without material removed. The uncut portions on the bottom plate 20 are respectively clamped and matched with the corresponding first locking portion 2631, second locking portion 2731, and third locking portion 2911, enhancing the structural stability of the first inner clamp 2 and preventing the first inner clamp 2 from deforming.

[0070] There are two fourth locking portions 201 on the bottom plate 20 in this embodiment, which are arranged at intervals in the first direction. The uncut portion on one of the fourth locking portions 201 is clamped and matched with the first locking portion 2631, and the uncut portion on the other fourth locking portion 201 is simultaneously clamped and matched with the second locking portion 2731 and the third locking portion 2911.

[0071] Continue as Figure 7 shown, the lengths of the first buffer plate 264 and the second buffer plate 274 are both equal to the width of the bottom plate 20, so that a plurality of first buffer plates 264 are stacked and folded to form the top wall of the first inner clamp 2. A plurality of second buffer plates 274 are stacked and folded to form the bottom wall of the first inner clamp 2. The number of the first buffer plates 264 and the second buffer plates 274 in this embodiment is three each. The three first buffer plates 264 and the three second buffer plates 274 are respectively stacked and folded into the top wall and the bottom wall of the first inner clamp 2, so that the top and bottom of the first inner clamp 2 have good buffering effects, which is beneficial to protecting the safety of the inner lock body and the outer lock body, and further avoiding the increase in the manufacturing cost of the packaging box due to the addition of other buffer materials.

[0072] As Figure 7 and Figure 8 shown, the top edge of the first side plate 21 extends outward to form a third buffer plate 211, the bottom edge of the first side plate 21 extends outward to form a fourth buffer plate 212, the top edge of the second side plate 22 extends outward to form a fifth buffer plate 221, and the bottom edge of the second side plate 22 extends outward to form a sixth buffer plate 222. On the basis of the above steps, continue to fold, fold the third buffer plate 211 and the fifth buffer plate 221 towards the first inner clamp 2 and form a buffer layer on the top wall of the first inner clamp 2. Fold the fourth buffer plate 212 and the sixth buffer plate 222 towards the first inner clamp 2 and form a buffer layer on the bottom wall of the first inner clamp 2.

[0073] At this time, the third buffer plate 211 and the fifth buffer plate 221 are respectively stacked on the first buffer plate 264, and the fourth buffer plate 212 and the sixth buffer plate 222 are respectively stacked on the second buffer plate 274, further enhancing the buffering effects of the top wall and the bottom wall of the first inner clamp 2 and improving the protection strength for the inner lock body and the outer lock body.

[0074] As Figure 2 and Figure 8As shown, the top edge of the bottom plate 20 extends outward to form a third side plate 24 and a first tongue 241 that are connected in sequence, and the bottom edge of the bottom plate 20 extends outward to form a fourth side plate 25 and a second tongue 251 that are connected in sequence. The third side plate 24 is folded upward to form the top wall of the first inner clip 2, and the first tongue 241 is respectively inserted into the first buffer cavity and the third buffer cavity. The fourth side plate 25 is folded upward to form the bottom wall of the first inner clip 2, and the second tongue 251 is respectively inserted into the second buffer cavity and the fourth buffer cavity.

[0075] Specifically, the first tongue 241 can be inserted into the first buffer cavity between the first top plate 231 and the first buffer plate 264, and the first tongue 241 can be inserted into the third buffer cavity between the second top plate 232 and the first buffer plate 264. The second tongue 251 can be inserted into the second buffer cavity between the first top plate 231 and the second buffer plate 274, and the second tongue 251 can be inserted into the fourth buffer cavity between the second top plate 232 and the second buffer plate 274. By the first tongue 241 and the second tongue 251, the structure of the first inner clip 2 is locked, improving the structural stability of the first inner clip 2, making the structure of the first inner clip 2 more stable and reliable, and enhancing the protection strength of the door lock.

[0076] In this embodiment, the first tongue 241 has a first relief groove 2411, and the first relief groove 2411 is disposed opposite to the first card slot 210 to make way for the first card slot 210. The second tongue 251 has a second relief groove 2511, and the second relief groove 2511 is disposed opposite to the second card slot 220 to make way for the second card slot 220, avoiding interference between the first tongue 241 and the first card slot 210 and between the second tongue 251 and the second card slot 220.

[0077] Specifically, by cutting off a part of the material at the edge of the corresponding position of the first tongue 241, the first relief groove 2411 can be obtained, and the width of the first relief groove 2411 is equal to or greater than the groove width of the first card slot 210. Similarly, by cutting off a part of the material at the edge of the corresponding position of the second tongue 251, the second relief groove 2511 can be obtained, and the width of the second relief groove 2511 is equal to or greater than the groove width of the second card slot 220.

[0078] The above embodiments only illustrate the basic principles and characteristics of the present invention. The present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, there are various changes and modifications to the present invention, and these changes and modifications all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
