Description

Technical Field

[0001] This utility model relates to the field of plastic box technology, and in particular to a plastic box with a printed coating. Background Technology

[0002] Plastic boxes are transparent folding boxes, cylinders, hinged boxes, tote bags, hanging tags, and other related plastic products made of materials such as PVC / PET / PP / PS. They can be printed with UV offset printing, screen printing, hot stamping (gold / silver), and frosted finishes. Plastic boxes offer advantages such as enhanced user experience, durable packaging, moisture resistance, waterproofing, high toughness, strong transportation safety, and improved product image.

[0003] Currently, during the production process of plastic boxes, printing and spraying are often performed on the outer surface of the plastic boxes to form a printed and sprayed coating layer.

[0004] However, the above-mentioned printed coating is easily damaged because it does not have a protective mechanism on the outside. To avoid this, some plastic boxes will have a corresponding transparent shell on the outside for protection. However, such transparent shells are generally connected by adhesive, and it is not easy to replace them after they are damaged. Therefore, we propose a plastic box with a printed coating. Utility Model Content

[0005] The purpose of this utility model is to provide a plastic box with a printed coating. By setting a protective mechanism, it is convenient to connect the rotating sleeve and the locking component using a snap-fit ​​component. Then, the rotating sleeve drives the locking component to rotate, so that the locking component locks the protective cover, and the protective cover protects the plastic box body.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plastic box with a printed coating, comprising a plastic box body, wherein a protective mechanism is provided on the plastic box body, the protective mechanism comprising:

[0007] A protective cover is provided on the outer surface of the plastic box body, and the protective cover is used to protect the plastic box body.

[0008] A fixed threaded rod is fixedly connected to the bottom end of the plastic box body;

[0009] A locking assembly is threadedly connected to one end of a fixed threaded rod, and the locking assembly is used to lock the protective cover;

[0010] A rotating sleeve is fitted onto the outer surface of the locking assembly, and the rotating sleeve is used to drive the locking assembly to rotate.

[0011] A snap-fit ​​assembly is provided between the locking assembly and the rotating sleeve, and the snap-fit ​​assembly is used to snap the locking assembly and the rotating sleeve together.

[0012] Preferably, the locking assembly includes a locking sleeve threaded to the outer surface of the fixed threaded rod and a compression ring fixedly connected to the end of the locking sleeve, wherein the compression ring is used to compress the protective cover.

[0013] Preferably, the protective cover consists of a cover body and a folded edge located at the top of the cover body, and the cover body and the folded edge are integrally formed.

[0014] Preferably, the plastic box body is composed of a box body and a box edge fixedly connected to the top of the box body, and a sealing gasket is fixedly connected to the bottom inside the protective cover.

[0015] Preferably, a sealing strip is fixedly connected to the inside of the box edge, and the sealing strip is set as a V-shaped rubber pad.

[0016] Preferably, the snap-fit ​​assembly includes a positioning ring fixedly connected to the middle of the locking sleeve, through grooves on both sides of the positioning ring, limiting grooves on the other two sides of the positioning ring, a stop ring fixedly connected to the end of the locking sleeve, a limiting block fixedly connected to the inside of the rotating sleeve, and a return spring sleeved on the outer surface of the locking sleeve.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] The rotating sleeve is engaged with the locking component via a snap-fit ​​assembly. Then, the rotating sleeve is rotated, causing the locking component to rotate and gradually separate from the fixed threaded rod. The protective cover is then replaced, and the rotating sleeve is reversed to allow the locking component to engage with the fixed threaded rod again, thus securing the protective cover. At this point, the protective cover can protect the coating on the outer surface of the plastic box body, preventing damage. This design not only protects the coating on the plastic box body but also facilitates the replacement of the protective cover later. Attached Figure Description

[0025] 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.

[0026] This utility model provides, for example Figure 1-5 The illustrated plastic box with a printed coating includes a plastic box body 1. A protective mechanism is provided on the plastic box body 1, comprising: a protective cover 2, which is fitted onto the outer surface of the plastic box body 1 and serves to protect the plastic box body 1; a fixed threaded rod 5, which is fixedly connected to the bottom end of the plastic box body 1; a locking assembly 6, which is threadedly connected to one end of the fixed threaded rod 5 and serves to lock the protective cover 2; a rotating sleeve 8, which is fitted onto the outer surface of the locking assembly 6 and serves to drive the locking assembly 6 to rotate; and a snap-fit ​​assembly 7, which provides a snap-fit ​​connection between the locking assembly 6 and the rotating sleeve 8. Component 7, and the snap-fit ​​component 7 is used to lock the component 6 and the rotating sleeve 8. When the protective cover 2 needs to be replaced, the rotating sleeve 8 and the locking component 6 are snapped together by the snap-fit ​​component 7. Then the rotating sleeve 8 is rotated, so that the locking component 6 rotates and gradually separates from the fixed threaded rod 5. Then the protective cover 2 is removed and replaced. The hole in the middle of the protective cover 2 is inserted into the fixed threaded rod 5. Then the rotating sleeve 8 is reversed, so that the locking component 6 is screwed into the fixed threaded rod 5 again. Thus, the protective cover 2 is fixed by the locking component 6. At this time, the protective cover 2 can be used to protect the coating on the outer surface of the plastic box body 1, thereby avoiding damage.

[0027] It should be further explained that the locking assembly 6 includes a locking sleeve 602 that is threaded to the outer surface of the fixed threaded rod 5 and a compression ring 601 that is fixedly connected to the end of the locking sleeve 602. The compression ring 601 is used to compress the protective cover 2. By rotating the locking sleeve 602 along the fixed threaded rod 5, the compression ring 601 is used to compress the protective cover 2, thereby fixing the protective cover 2.

[0028] Furthermore, the protective cover 2 is composed of a cover body 201 and a folded edge 202 located at the top of the cover body 201, and the cover body 201 and the folded edge 202 are integrally formed; the integrally formed protective cover 2 has good structural stability and avoids easy damage.

[0029] Furthermore, the plastic box body 1 is composed of a box body 101 and a box edge 102 fixedly connected to the top of the box body 101, and a sealing gasket 4 is fixedly connected to the bottom inside the protective cover 2; by squeezing the sealing gasket 4 at the bottom of the protective cover 2 by the box body 101, a large number of impurities are prevented from entering the side of the protective cover 2 and causing them to adhere to the coating of the box body 101.

[0030] Furthermore, a sealing strip 3 is fixedly connected inside the box edge 102, and the sealing strip 3 is set as a V-shaped rubber pad; by pressing the sealing strip 3 with the folded edge 202, the sealing strip 3 is deformed and tightly attached to the folded edge 202, thereby achieving a certain sealing effect and preventing impurities from entering.

[0031] Furthermore, the locking assembly 7 includes a positioning ring 701 fixedly connected to the middle of the locking sleeve 602, through grooves 702 on both sides of the positioning ring 701, limiting grooves 703 on the other two sides of the positioning ring 701, a stop ring 704 fixedly connected to the end of the locking sleeve 602, a limiting block 705 fixedly connected to the inside of the rotating sleeve 8, and a return spring 706 sleeved on the outer surface of the locking sleeve 602. When the rotating sleeve 8 is needed to drive the locking assembly 6 to rotate, the rotating sleeve 8 is moved upward, causing the limiting block 705 to move along the through groove 702 and compress the return spring 706 until the limiting block 705 crosses the through groove 702. Then, the rotating sleeve 8 is rotated ninety degrees, so that the limiting block 705 is aligned with the limiting groove 703, causing the return spring 706 to slightly... Slightly reset the sleeve to allow the limiting block 705 to engage with the limiting groove 703. Then rotate the rotating sleeve 8 to allow the locking assembly 6 to rotate. When the rotating sleeve 8 is not needed, move the rotating sleeve 8 upward to separate the limiting block 705 from the limiting groove 703. Then rotate the rotating sleeve 8 ninety degrees to align the limiting block 705 with the through groove 702. Then the reset spring 706 resets, driving the rotating sleeve 8 to move, allowing the limiting block 705 to return from the through groove 702. At this point, the rotating sleeve 8 can be rotated. The limiting block 705 will only rotate above the stop ring 704 and will not cause the locking assembly 6 to rotate. This makes the protective cover 2 more stable after installation and will not easily cause the protective cover 2 to move, allowing impurities to enter through the installation gap between the protective cover 2 and the box 101.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
