[0002] Three-dimensional puzzle paper card toys are a DIY toy that combines entertainment, knowledge and appreciation. They are mainly made of paper cards and can be assembled without any auxiliary tools. The design of three-dimensional puzzle paper card toys is flexible and diverse, and can be assembled into various three-dimensional models, such as buildings, trees and other three-dimensional models.

[0003] In order to facilitate the splicing of paper cards, it is necessary to open a card slot on the paper card corresponding to the thickness of the paper card. The thickness of conventional paper cards is 1.2-2.5mm and the shape of the card slot is rectangular. The paper slotting method is mostly done by punching with a die. The pressure required for die punching is relatively large, and the overall thickness of the die-cutting blade of the die needs to be large enough. However, due to the thin thickness of the paper card and the small width of the card slot, the die cannot meet the punching accuracy requirements, that is, it is impossible to open a card slot on the paper card and batch processing cannot be achieved. Summary of the invention

[0004] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the utility model is to provide a paper card with a card point type slot.

[0006] Preferably, the horizontal distance between the card points on both sides of the card slot is 2.0 mm, and the thickness of the paper card body is 2.0 mm.

[0007] Preferably, the slot is in an hourglass shape.

[0008] Preferably, the slot is in a side-bent C-shape.

[0009] Preferably, two symmetrically arranged convex arc structures are convexly provided on the inner walls on both sides of the middle portion of the slot.

[0010] Preferably, the maximum width of the flared opening is 3-5 mm.

[0011] The beneficial effects of the utility model are as follows: the paper card with a card point type slot of the utility model comprises a paper card body, the paper card body is provided with a card slot for carding with other paper card bodies, inner walls on both sides of the middle of the card slot are mutually contracted and respectively form at least one card point for carding with other paper card bodies, the horizontal distance between the card points on both sides in the card slot is 1.2-2.5mm, the inner walls on both sides of the end of the card slot are mutually expanded to form a flared structure, the horizontal distance of the flared is greater than the horizontal distance between the card points on both sides in the card slot, and the thickness of the paper card body is equal to the horizontal distance between the card points on both sides in the card slot; the above structural design can not only ensure that the paper card body is carded with other paper card bodies by means of the card points on both sides in the card slot, but also make the overall width of the card slot larger, so that a matching die cutting knife plate can be made in the actual production process for die cutting, and the efficiency of opening the card slot of the paper card is improved, so as to realize batch processing.

[0019] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0020] like Figure 1-4As shown, a paper card with a card point 3-type slot includes a paper card body 1, the paper card body 1 is provided with a card slot 2 for carding with other paper card bodies 1, the inner walls on both sides of the middle of the card slot 2 are mutually contracted and respectively form at least one card point 3 for carding with other paper card bodies 1, the horizontal distance between the card points 3 on both sides in the card slot 2 is 1.2-2.5mm, the inner walls on both sides of the end of the card slot 2 are mutually expanded to form a flared 4 structure, the horizontal distance of the flared 4 is greater than the horizontal distance between the card points 3 on both sides in the card slot 2, and the thickness of the paper card body 1 is equal to the horizontal distance between the card points 3 on both sides in the card slot 2.

[0021] The paper card with a card point 3-type slot includes a paper card body 1, wherein the paper card body 1 is provided with a card slot 2 for carding with other paper card bodies 1, inner walls on both sides of the middle of the card slot 2 are mutually contracted and respectively form at least one card point 3 for carding with other paper card bodies 1, the horizontal distance between the card points 3 on both sides in the card slot 2 is 1.2-2.5 mm, the inner walls on both sides of the end of the card slot 2 are mutually expanded to form a flared opening 4 structure, the horizontal distance of the flared opening 4 is greater than the horizontal distance between the card points 3 on both sides in the card slot 2, and the thickness of the paper card body 1 is equal to the horizontal distance between the card points 3 on both sides in the card slot 2; the above structural design can ensure that the paper card body 1 is carded with other paper card bodies 1 by means of the card points 3 on both sides in the card slot 2, and the overall width of the card slot 2 can be made larger, so that a matching die-cutting knife plate can be made in the actual production process for die-cutting, and the efficiency of opening the card slot 2 on the paper card is improved, so as to realize batch processing.

[0022] Furthermore, the horizontal distance between the card points 3 on both sides of the card slot 2 is 2.0 mm, and the thickness of the paper card body 1 is 2.0 mm. On the one hand, it ensures that the paper card body 1 is engaged with other paper card bodies 1 by means of the card points 3 on both sides of the card slot 2, and on the other hand, it ensures that the paper card body 1 has sufficient rigidity for users to splice and use, and saves material costs.

[0023] Furthermore, the shape of the card slot 2 is an hourglass shape, or the shape of the card slot 2 is a side-bent C shape, or the inner walls on both sides of the middle of the card slot 2 are convexly provided with two symmetrically arranged convex arc structures 5; the above schemes can be implemented, which can not only ensure that the paper card body 1 is engaged with other paper card bodies 1 by means of the card points 3 on both sides of the card slot 2, but also make the overall width of the card slot 2 larger, so that matching die-cutting blades can be made for die cutting in the actual production process, thereby improving the efficiency of opening the card slot 2 on the paper card, so as to realize batch processing. In this embodiment, the shape of the card slot 2 is an hourglass shape; in a three-dimensional puzzle paper card toy, for example, a three-dimensional tea tree puzzle paper card toy, such as Figure 5-6 As shown, the card slot 2 provided in different paper card bodies 1 may be in an hourglass shape, or in a side-bent C shape, or may have two symmetrically arranged convex arc structures 5 protruding from the inner walls on both sides of the middle.

[0024] Furthermore, the maximum width of the flared opening 4 is 3-5 mm, which can make the overall width of the card slot 2 larger, so that a matching die-cutting blade can be made for die-cutting in the actual production process, and the efficiency of opening the card slot 2 of the paper card can be improved, so as to realize batch processing; on the other hand, the flared opening 4 structure is more convenient for users to snap-fit ​​the paper card body 1 with another paper card body 1, so as to avoid the impact of the width of the card slot 2 when the two paper card bodies 1 are spliced, which hinders the snap-fit ​​and causes damage to the outer edge of the card slot 2 of the paper card body 1. In this embodiment, the maximum width of the flared opening 4 is 3 mm.

[0025] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the protection scope of the present invention.
