Technical Field

[0001] The utility model relates to the technical field of corrugated paper packaging boxes, in particular to an environment-friendly self-locking corrugated paper packaging box. Background Technique

[0002] A self-locking packaging box, as the name implies, is a packaging container with a self-locking or fastening function. The design of this packaging box aims to ensure the stability and safety of the contents during transportation and storage without the need for additional locks, tapes or other fastening devices.

[0003] For the existing self-locking corrugated paper packaging box, the self-locking operation is generally completed through the clamping structure after the bottom tray and the box surface of the packaging box are folded, which makes the bottom tray of the packaging box consume more materials, resulting in waste of resources. And for the top cover of the packaging box, the sealing operation of the packaging box is generally carried out by folding the box surface and using tape. In addition to consuming more materials, certain consumables are also required to complete the sealing operation of the box cover of the packaging box, which is very troublesome. Content of the Utility Model

[0004] The purpose of the utility model is to provide an environment-friendly self-locking corrugated paper packaging box to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: An environment-friendly self-locking corrugated paper packaging box, including a fence and two box covers. Both ends of the fence are respectively inserted into the two box covers and are in contact with the inner walls of the two box covers. The fence and the box covers are connected by a self-locking component;

[0006] The self-locking component includes four paper tubes. The four paper tubes are installed through the four corners inside the fence. Circular holes are opened at the four corners of the box cover. Elastic rings are fixedly installed at the positions corresponding to the circular holes on the box cover. And both ends of the paper tube respectively penetrate through the corresponding circular hole and the corresponding elastic ring.

[0007] Preferably, two soft rings are fixedly installed at both the upper and lower ends of the fence, and each soft ring is in interference fit with the inner wall of the corresponding box cover.

[0008] Preferably, the paper tube is mainly composed of a round tube, two connecting tubes and two limiting rings. Each connecting tube is arranged between the corresponding round tube and the corresponding limiting ring. Both ends of the connecting tube are fixedly connected to the corresponding round tube and the corresponding limiting ring respectively. The outer peripheral wall of the round tube is fixedly connected to the inner wall of the fence.

[0009] Preferably, the outer ring wall of the limiting ring is arranged in an arc shape. A plurality of breaks are arranged in a circumferential array on the inner ring wall of the elastic ring, and the elastic ring is an elastic plastic ring.

[0010] Preferably, the outer diameter of the circular tube is greater than the inner diameter of the circular hole, the outer diameter of the connecting tube is less than the inner diameter of the circular hole, the outer diameter of the limiting ring is greater than the outer diameter of the circular hole, and the inner diameter of the limiting ring is equal to the outer diameter of the connecting tube.

[0011] Preferably, a waterproof film is fixedly installed on the outer wall of the box cover, and the elastic ring fixedly penetrates through the corresponding waterproof film.

[0012] The utility model at least has the following beneficial effects:

[0013] 1. When the improved self-locking corrugated paper packaging box is used, the operator sequentially sleeves two box covers on both ends of the enclosure, so that both ends of the paper tube sequentially pass through the corresponding circular holes and elastic rings. At this time, due to the mutual contact between the paper tube and the elastic ring, the position between the enclosure and the box cover can be directly locked. At the same time, through the support of the paper tube for the corrugated paper packaging box, the strength of the corrugated paper packaging box can be enhanced. The assembly operation of the corrugated paper packaging box is simple, and the corrugated paper packaging box consumes less materials, reducing the loss of raw materials during the production of the corrugated paper packaging box, making the production of the corrugated paper packaging box more environmentally friendly;

[0014] 2. After the above-mentioned corrugated paper packaging box is assembled, when the corrugated paper packaging box is placed on the external ground, the paper tube can be used as a support foot to stably support the corrugated paper packaging box. There is always a specific distance between the corrugated paper packaging box and the ground, which cooperates with the isolation of the waterproof film. With the barrier of the waterproof film, the moisture on the ground hardly invades the corrugated cardboard of the corrugated paper packaging box, causing damage to the corrugated paper packaging box, extending the service life of the corrugated paper packaging box, and further avoiding the loss during the use of the corrugated paper packaging box.

[0023] In order to make the technical solution and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] The utility model provides a technical solution: Figure 1 - Figure 6 The utility model discloses an environmentally friendly self-locking corrugated paper packaging box, comprising a fence 1 and two box covers 2, the two ends of the fence 1 are respectively inserted into the two box covers 2 and connected with the inner walls of the two box covers 2, and the fence 1 and the box covers 2 are connected by a self-locking component 3;

[0025] The self-locking assembly 3 includes four paper tubes 31, which are installed at the four corners of the enclosure 1. Circular holes 32 are opened at the four corners of the box cover 2. Elastic rings 33 are fixedly installed at the positions corresponding to the circular holes 32 on the box cover 2, and the two ends of the paper tubes 31 respectively penetrate the corresponding circular holes 32 and the corresponding elastic rings 33.

[0026] In this embodiment, when the improved self-locking corrugated paper packaging box is used, the operator sequentially puts the two box covers 2 on the two ends of the enclosure 1, and then the two ends of the paper tube 31 sequentially pass through the corresponding circular holes 32 and the elastic ring 33. At this time, due to the mutual interference between the two ends of the paper tube 31 and the elastic ring 33, the position between the enclosure 1 and the box cover 2 can be directly locked, so that the box cover 2 can be stably sleeved on the two ends of the enclosure 1, and the operator does not need to perform other operations. The assembly operation of the corrugated paper packaging box is simple, and the paper tube 31 can support the corrugated paper packaging box to a certain extent to enhance the strength of the corrugated paper packaging box. The locking operation between the enclosure 1 and the box cover 2 does not require a large amount of cardboard folding and clamping, thereby reducing the loss of raw materials when making the corrugated paper packaging box, making the production of corrugated paper packaging boxes more environmentally friendly;

[0027] After the above corrugated paper packaging box is assembled, when the corrugated paper packaging box is placed on the external ground, the paper tube 31 can be used as a support foot to stably support the corrugated paper packaging box. There is always a specific distance between the corrugated paper packaging box and the ground, which can greatly reduce the amount of water vapor invading the corrugated board inside the corrugated paper packaging box, avoid damage to the corrugated paper packaging box due to excessive water vapor invasion, and extend the service life of the corrugated paper packaging box.

[0028] In a further preferred embodiment of the present invention, as Figure 1 and Figure 2 shown, two soft rings 4 are fixedly installed at both the upper and lower ends of the enclosure 1, and each soft ring 4 is in interference fit with the inner wall of the corresponding box cover 2;

[0029] In this embodiment, after the above box cover 2 and the enclosure 1 are assembled, due to the fitting of the soft ring 4 with the inner wall of the box cover 2, the gap between the enclosure 1 and the inner wall of the box cover 2 can be automatically sealed, so that a relatively closed space is formed inside the corrugated paper packaging box.

[0030] In a further preferred embodiment of the present invention, as Figure 2 and Figure 5 shown, the paper tube 31 is mainly composed of a round tube 311, two connecting tubes 312 and two limiting rings 313. Each connecting tube 312 is arranged between the corresponding round tube 311 and the corresponding limiting ring 313. The two ends of the connecting tube 312 are fixedly connected to the corresponding round tube 311 and the corresponding limiting ring 313 respectively, and the outer peripheral wall of the round tube 311 is fixedly connected to the inner wall of the enclosure 1;

[0031] In this embodiment, the paper tube 31 composed of the round tube 311, two connecting tubes 312 and two limiting rings 313 can form an annular card slot at both ends of the paper tube 31 for the limiting ring 313 to be engaged and abutted with the paper tube 31.

[0032] In a further preferred embodiment of the present invention, as Figure 3 , Figure 4 and Figure 6 shown, the outer ring wall of the limiting ring 313 is arranged in an arc shape. A plurality of breaks 331 are arranged in a circumferential array on the inner ring wall of the elastic ring 33, and the elastic ring 33 is an elastic plastic ring;

[0033] In this embodiment, the setting of the breaks 331 of the limiting ring 313 enables a certain degree of bending deformation inside the limiting ring 313;

[0034] When the box cover 2 is put on the enclosure 1, due to the mutual interference between the arc surface of the limiting ring 313 and the elastic ring 33, the inside of the elastic ring 33 can be bent outward and the diameter of the inner hole of the elastic ring 33 can be automatically adjusted, so that the limiting ring 313 can directly pass through the elastic ring 33.

[0035] In a further preferred embodiment of the present invention, Figure 5 As shown, the outer diameter of the circular tube 311 is larger than the inner diameter of the circular hole 32, the outer diameter of the connecting tube 312 is smaller than the inner diameter of the circular hole 32, the outer diameter of the limiting ring 313 is larger than the outer diameter of the circular hole 32, and the inner diameter of the limiting ring 313 is equal to the outer diameter of the connecting tube 312;

[0036] In this embodiment, the outer diameter of the circular tube 311 is larger than the outer diameter of the circular hole 32, so that when the box cover 2 is subjected to greater pressure, the circular tube 311 can support and limit the box cover 2 to a certain extent at the four corners of the box cover 2, so as to enhance the strength of the corrugated paper packaging box. In addition, due to the mutual interference between the connecting tube 312 and the inner wall of the elastic ring 33, and the constraint and limitation of the four corners of the enclosure 1 by the circular tube 311, the strength of the enclosure 1 can be simultaneously enhanced.

[0037] In a further preferred embodiment of the present invention, Figure 1 , Figure 3 and Figure 4 As shown, a waterproof membrane 5 is fixedly mounted on the outer wall of the box cover 2, and an elastic ring 33 is fixedly passed through the corresponding waterproof membrane 5;

[0038] In this embodiment, the provision of the waterproof membrane 5 can enhance the connection strength between the elastic ring 33 and the box cover 2 , and at the same time the waterproof membrane 5 can protect the box cover 2 to isolate the box cover 2 from contact between ground water vapor and the box cover 2 .

[0039] Working principle: When the improved self-locking corrugated paper packaging box is used, the operator first unfolds the enclosure 1, then puts the cover on the enclosure 1, and inserts the corresponding connecting holes and the limiting ring 313 into the circular hole 32, and then the operator presses the four corners of the box cover 2 in the direction of the enclosure 1, first making the limiting ring 313 slide out of the circular hole 32, and then due to the mutual interference between the limiting ring 313 and the elastic ring 33, the inside of the elastic ring 33 bends outward, and the inner diameter of the elastic ring 33 is automatically adjusted, so that the limiting ring 313 can pass through the elastic ring 33, and then the box cover 2 is continued to be pressed. The box cover 2 squeezes the soft ring 4, causing the soft ring 4 to shrink slightly, thereby reducing the distance between the enclosure 1 and the box cover 2, so that the limit ring 313 can pass through the elastic ring 33. At this time, due to the deformation and reset of the elastic ring 33, the bent part of the elastic ring 33 automatically resets and deforms to insert between the limit ring 313 and the box cover 2. Then the operator releases the box cover 2, and the soft ring 4 automatically resets and pushes the box cover 2 away from the enclosure 1. The distance between the box cover 2 and the enclosure 1 is automatically reset until the elastic ring 33, the box cover 2 and the limit ring 313 conflict with each other, and the position between the box cover 2 and the enclosure 1 is locked.

[0040] It should be noted that after the assembly between the box cover 2 and the enclosure 1 is completed, if the box cover 2 is pushed by an external force to move away from the enclosure 1, the inner part of the elastic ring 33 bends and deforms toward the circular hole 32 due to the mutual interference between the limit ring 313 and the elastic ring 33. Since part of the elastic ring 33 fills the inner part of the circular hole 32, the inner diameter of the circular hole 32 is reduced. At this time, the limit ring 313 cannot be inserted into the circular hole 32, and the position between the box cover 2 and the enclosure 1 is locked;

[0041] After the assembly between the box cover 2 and the enclosure 1 is completed, the operator assembles the enclosure 1 and the box cover 2, and then the operator can put the items into the corrugated paper packaging box through the opening of the enclosure 1, and then assemble the enclosure 1 with another box cover 2 according to the above operator. At this time, due to the soft ring 4 blocking the gap between the enclosure 1 and the box cover 2, a relatively closed space is formed inside the corrugated paper packaging box;

[0042] It should be noted that when the corrugated paper box is placed on the ground or on a table, the limiting ring 313 can be used as a supporting foot to stably support the corrugated paper box. There is always a specific distance between the corrugated paper box and the ground, and the moisture on the ground hardly invades the corrugated paper board of the corrugated paper box. When the corrugated paper box is placed on the table, the support of the box cover 2 and the enclosure 1 by the round tube 311 can greatly enhance the strength of the corrugated paper box.

[0043] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present utility model. Without departing from the spirit and scope of the present utility model, various changes and improvements will occur to the present utility model, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection required by the present utility model is defined by the appended claims and their equivalents.
