Description

Technical Field

[0001] The utility model relates to the field of anti-counterfeiting packaging, and in particular to a buckle body, a snap fitting, an anti-counterfeiting buckle and a packaging box. Background Art

[0002] Traditional gift and wine packaging are sealed with rivets. Patent document CN205633554U discloses an anti-counterfeiting package box with an anti-counterfeiting cover and an elastic member that can separate the box body from the base. When opening the box, the consumer peels off the anti-counterfeiting cover and manually operates the elastic member operating part to deform the elastic member to open the box. Since paper packaging is easy to deform, the box body is deformed under the external force of the counterfeiter, which can easily cause the elastic member to deform and make the anti-counterfeiting ineffective. Counterfeiters can also use a steel ruler to insert the gap between the box body and the anti-counterfeiting cover to push the elastic member apart to make it ineffective. Utility Model Content

DETAILED DESCRIPTION

[0083] The utility model is described in detail below in conjunction with specific embodiments. The following embodiments will help those skilled in the art to further understand the utility model, but do not limit the utility model in any form. It should be pointed out that for those of ordinary skill in the art, several changes and improvements can be made without departing from the concept of the utility model. These all belong to the protection scope of the utility model.

[0084] Example 1

[0085] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this embodiment provides a buckle body 1, including: an embedded part 101, an extension part 109, a snap-fit ​​fixing part 105 and a first snap-fit ​​part 104. One end of the extension part 109 is connected to the embedded part 101, and the other end is a free end. The extension part 109 and the embedded part 101 constitute a card slot 100, wherein a part of the extension part 109 constitutes the bottom of the card slot 100, which is recorded as the bottom part, and the other part and the embedded part 101 respectively constitute two side walls of the card slot 100, which are recorded as the side wall part. The free end of the extension part 109 is bent in a direction away from the embedded part 101, which plays a certain guiding role and facilitates the insertion of the snap-fit ​​into the card slot 100. A reinforcing rib 108 can also be connected to the extension part 109 outside the card slot 100 to increase the anti-deformation ability of the extension part 109.

[0086] The first clamping portion 104 is located in the card slot 100, one end of which is connected to the side wall portion / embedded portion 101 of the extension portion 109, and the other end is a free end. The free end of the first clamping portion 104 extends toward the bottom of the card slot 100, and a first gap 1041 is provided between the free end of the first clamping portion 104 and the side wall portion / embedded portion 101 of the extension portion 109. When the clamping slot of the clamping member is engaged with the first clamping portion 104, if the clamping member is pulled out of the card slot 100 by an external force, the edge of the clamping slot of the clamping member will enter the first gap 1041 and be blocked and limited by the first clamping portion 104. The first clamping portion 104 is an elastic structure, so that the clamping member can be reset after insertion to achieve clamping. A ratchet structure is provided at the end of the free end of the first clamping portion 104. After the clamping piece is inserted into the clamping slot 100, if the clamping piece moves outward due to external force, the ratchet structure will be inserted into the packaging box where the clamping piece is installed, thereby increasing the difficulty of pulling out the clamping piece and achieving the purpose of increasing the difficulty of counterfeiting by destroying the packaging box.

[0087] The engaging member fixing portion 105 is located in the card slot 100 and connected to the side wall portion of the embedded portion 101 and / or the extending portion 109. A second gap 1051 is provided between the engaging member fixing portion 105 and the side wall portion of the extending portion 109 / the embedded portion 101. Specifically, as Figure 7As shown, one side of the clamping member fixing portion 105 can be connected to the embedded portion 101, and the other side opposite to it does not contact the side wall portion of the extension portion 109, thereby forming a second gap 1051; or, one side of the clamping member fixing portion 105 can be connected to the side wall portion of the extension portion 109, and the other side opposite to it does not contact the embedded portion 101, thereby forming a second gap 1051; in addition, in the above two cases, the clamping member fixing portion 105 can be connected to the groove bottom portion of the extension portion 109 at the same time. The side of the clamping member fixing portion 105 facing the notch of the card slot 100 is a guide surface, as shown in FIG. Figure 2 As shown, the included angle α between the guide surface and the side wall of the embedded portion 101 / extending portion 109 is less than or equal to 45 degrees, so as to increase the guiding effect of the engaging member. The guide surface is an inclined surface or an arc surface, which is used to guide the engaging member into the second gap 1051 during the insertion of the engaging member into the slot 100, thereby limiting the engaging member to a certain extent. Figure 5 As shown, one side of the fixing portion 105 of the engaging member connected to the bottom of the card slot 100 converges to the middle of the bottom of the slot in an arc shape, which is used to increase the contact area between the fixing portion 105 of the engaging member and the engaging member, and reduce the possibility of the engaging member escaping from the second gap 1051. In this way, the buckle body 1 and the engaging member 2 can be effectively and tightly engaged. After the engaging member enters the second gap 1051 and is engaged with the first clamping portion 104, the engaging member can be fastened in the second gap 1051, reducing the movable space between the buckle body 1 and the engaging member, so that it is difficult for counterfeiters to make the buckle body and the engaging member move relative to each other by applying external force to generate a gap, which increases the difficulty of the prying tool touching the clamping portion, that is, increases the difficulty of counterfeiting, and at the same time, the anti-deformation ability of the box cover / box body where the engaging member is located can also be improved.

[0088] In order to further improve the anti-pry effect of the buckle body, the present embodiment further provides guide portions 106 on the left and right sides of the card slot 100 , and the guide portions 106 are connected to the embedded portion 101 and / or the extension portion 109 to shield the first clamping portion 104 and the second gap 1051 from both sides.

[0089] The guide portion 106 can be connected to both the embedded portion 101 and the extension portion 109 to completely close the openings on the left and right sides, or it can be connected to only the embedded portion 101 or the extension portion 109, as long as it plays a shielding role. Figure 8 The guide portion 106 is connected to the embedded portion 101 and extends toward the side wall portion of the extension portion 109, or Fig. 9 As shown, the guide portion 106 is connected to the side wall portion of the extension portion 109 and extends toward the embedded portion 101, or Figure 1 As shown, the guide portion 106 connects the embedded portion 101 and the extending portion 109 at the same time.

[0090] like Figure 6 As shown, the guide portion 106 includes a top portion 1061, a transition portion 1062 and a main body portion 1063 which are sequentially connected from the slot opening to the slot bottom of the card slot 100. The top portion 1061 is arc-shaped, and the width of the transition portion 1062 gradually increases from the position where the top portion 1061 is connected to the position where the main body portion 1063 is connected. The arc-shaped top portion 1061 and the main body portion 1063 with gradually increasing width can play a guiding role, so that the insertion into the slot corresponding to the guide portion 106 is facilitated.

[0091] like Figure 7 As shown, in the case of the guide portion 106, the connection mode of the clamping member fixing portion 105 can be replaced by: connecting to any one or more of the guide portion 106, the embedded portion 101, and the extension portion 109. Specifically, the connection mode of the clamping member fixing portion 105 can be: connecting to the guide portion 106 and the extension portion 109, connecting to the guide portion 106 and the embedded portion 101, or connecting to the embedded portion 101, the extension portion 109, and the guide portion 106 at the same time, or only connecting to the guide portion 106, and the utility model does not limit this.

[0092] like Figure 1 and Figure 5 As shown, the buckle body 1 may further include a first limiting portion 102, which is connected to the embedded portion 101 / extending portion 109, i.e., the opposite side of the first clamping portion 104. The first limiting portion 102 is arranged along the direction from the slot opening to the slot bottom of the card slot 100, and the end of the first limiting portion 102 away from the slot bottom is an arc structure, which facilitates the smooth insertion of the engaging member, and the end of the first limiting portion 102 away from the slot opening is preferably connected to the slot bottom part of the extending portion 109. The first limiting portion 102 is used to limit the size of the space in the card slot 100, and clamps the engaging member installed on the box body with the side wall part of the extending portion 109 / embedded portion 101, so as to minimize its movable space in the card slot 100.

[0093] At this time, the connection mode of the clamping member fixing portion 105 can be replaced by: connecting any one or more of the first limiting portion 102, the embedded portion 101, the extension portion 109, and the guide portion 106. Specifically, the connection mode of the clamping member fixing portion 105 can be: connecting to the first limiting portion 102, connecting to the first limiting portion 102 and the guide portion 106, connecting to the first limiting portion 102 and the extension portion 109, connecting to the first limiting portion 102 and the embedded portion 101, or connecting to the embedded portion 101, the first limiting portion 102 and the extension portion 109, or connecting to the embedded portion 101, the first limiting portion 102, the extension portion 109, and the guide portion 106 at the same time, and the present utility model does not limit this.

[0094] In order to increase the engagement ability between the buckle body 1 and the engaging member, the buckle body 1 further includes a second clamping portion 103, which is located at the opposite side of the first clamping portion 104 in the clamping slot 100, that is, when one end of the first clamping portion 104 is connected to the side wall portion of the extension portion 109, one end of the second clamping portion 103 is connected to the embedded portion 101, and when one end of the first clamping portion 104 is connected to the embedded portion 101, one end of the second clamping portion 103 is connected to the side wall portion of the extension portion 109. The other end of the second clamping portion 103 is a free end, extending toward the bottom direction of the clamping slot 100. There is a third gap 1031 between the free end of the second clamping portion 103 and the side wall portion of the embedded portion 101 / extension portion 109. The second clamping portion 103 is partially or entirely projected on the side wall portion of the extension portion 109 on the opposite side / the embedded portion 101, and can be clamped together with the first clamping portion 104 into the clamping groove of the clamping member, or the clamping member can be pressed toward the first clamping portion 104 under its own elastic force, further limiting the free movement space of the clamping member. Similarly, the second clamping portion 103 is an elastic structure, and a ratchet structure is provided at the end of its free end.

[0095] When the engaging groove of the engaging member is engaged with the second engaging portion 103, if the engaging member is pulled out of the engaging groove 100 by an external force, the edge of the engaging groove of the engaging member will enter the third gap 1031 and be blocked and limited by the second engaging portion 103. When the second engaging portion 103 is pressed against the engaging member, if the engaging member is moved outward by an external force, the ratchet structure will be inserted into the packaging box where the engaging member is installed, thereby increasing the difficulty of pulling out the engaging member and achieving the purpose of increasing the difficulty of counterfeiting by destroying the packaging box.

[0096] In this embodiment, the number of the first clamping portion 104, the second clamping portion 103, and the clamping member fixing portion 105 can be one or more. Figure 5 As shown, when there are multiple first clamping parts 104, they are evenly distributed on both sides of the midline of the side wall part of the extension part 109 / embedded part 101, and correspondingly, the second clamping parts 103 are evenly distributed on both sides of the midline of the side wall part of the embedded part 101 / extension part 109, and at the same time, the clamping part fixing part 105 is evenly distributed on both sides of the midline of the embedded part 101 / extension part 109. Even distribution means that the number on both sides of the midline is the same and the distribution is even. Preferably, the first clamping part 104, the second clamping part 103, and the clamping part fixing part 105 are symmetrical on both sides with the midline as the symmetry axis, so as to increase the stability of the clamping.

[0097] The embedded part 101 of the buckle body 1 is used to be embedded in the packaging box to fix the buckle body 1. In order to increase the firmness of the fixation, the buckle body 1 also includes a body fixing part 107, which is connected to the guide part 106 outside the card slot 100. The body fixing part 107 protrudes in the direction away from the guide part 106. The body fixing part 107 is snapped into the packaging box to increase the firmness of the fixation of the two.

[0098] Example 2

[0099] This embodiment provides a snap-fitting member 2 adapted to the snap-fitting body of embodiment 1, and the snap-fitting member can be snap-fitted with the snap-fitting body.

[0100] like Fig.10 and Fig.11 As shown, the engaging member includes: an engaging member body 200, and an engaging groove 203 is provided on the engaging member body 200. The position of the engaging groove 203 corresponds to the position of the first engaging portion 104, and a protruding fixing portion 202 is provided on the engaging member body 200. The protruding fixing portion 202 is preferably an elastic structure.

[0101] During the clamping process, the first clamping portion 104 is squeezed by the clamping member 2 and elastically deformed, and finally buckled into the clamping groove 203 of the clamping member 2. The second clamping portion 103 is also squeezed by the clamping member 2 and elastically deformed, and finally buckled into the clamping groove 203 or presses the clamping member 2 toward the first clamping portion 104 under its own elastic force. During the clamping process, the protruding fixing portion 202 is elastically deformed by the guide surface, and finally enters the second gap 1051.

[0102] In the clamping state, the clamping groove 203 and the first clamping portion 104 are clamped with each other, and the second clamping portion 103 is buckled into the clamping groove 203 or presses the clamping member toward the first clamping portion 104 under its own elastic force. The protruding fixing portion 202 enters the second gap 1051, and the protruding fixing portion 202 is clamped or limited by the second gap 1051, thereby limiting the clamping member 2. The material of the clamping member is preferably silicon steel sheet.

[0103] In order to correspond to the guide portion 106, a guide groove 201 is provided on the engaging member body 200, the position of the guide groove 201 corresponds to the guide portion 106, and the protruding fixing portion 202 is connected to the inner wall of the guide groove 201. When the engaging member 2 is inserted into the buckle body 1, the guide portion 106 can enter the guide groove 201 to play a guiding role, so that the two can be smoothly engaged.

[0104] The engaging member 2 is connected to the packaging box. To increase the firmness of the connection, one side edge of the engaging member body 200 is at least partially bent to form an engaging member positioning portion 204. The engaging member positioning portion 204 is used to be inserted into a positioning opening provided on the packaging box.

[0105] In addition, at least one inner wall of the clamping groove 203 is bent to form a bent portion 205. Fig.12 As shown, the inner walls on the left and right sides of the clamping slot 203 are preferably bent to form two bent portions 205. In other embodiments, the inner walls on the four sides of the clamping slot 203 may also form bent portions 205 at the same time. Since a slot corresponding to the position of the clamping slot 203 needs to be provided on the packaging box, the bent portion 205 is located in the slot to protect the slot of the packaging box and reduce the deformation and damage of the first clamping portion 104 and the second clamping portion 103 under the action of external force.

[0106] Example 3

[0107] This embodiment provides an anti-counterfeiting buckle, including the buckle body of embodiment 1 and the engaging member of embodiment 2.

[0108] Example 4

[0109] like Fig.13 and Fig.14 As shown, this embodiment provides a packaging box, including a box cover 3, a box body 4 and an anti-counterfeiting buckle of embodiment 3, wherein the buckle body 1 is arranged on the side wall of the box cover 3 / box body 4, and the engaging member 2 is arranged on the side wall of the box body 4 / box cover 3. The packaging box is pasted with multiple layers of cardboard, and during the pasting process, the embedded part 101 is embedded inside the side wall of the box body 4 / box cover 3, and the rest is exposed outside.

[0110] The box body 4 / box cover 3 where the snap-fitting member 2 is located is provided with a groove corresponding to the snap-fitting groove 203, and the snap-fitting groove 203 overlaps with the groove, so that the inner and outer sides of the box body 4 / box cover 3 penetrate, so that the first snap-fitting portion 104 and the second snap-fitting portion 103 enter the snap-fitting groove 203 from both sides of the box body 4 / box cover 3 to complete the snap-fitting. The protruding fixing portion 202 of the snap-fitting member 2 is exposed from the box body 4 / box cover 3 and is located in the groove provided on the box body 4 / box cover 3, so as to be snapped into the second gap 1051.

[0111] A groove corresponding to the guide groove 201 is also provided on the box body 4 / box cover 3 where the locking member 2 is located, and the guide groove 201 overlaps with the groove, so that the inner and outer sides of the box body 4 / box cover 3 are penetrated, so that when the locking member 2 is inserted into the buckle body 1, the guide part 106 can enter the guide groove 201 more smoothly, reducing the interference of the box body 4 / box cover 3 on the guide part 106.

[0112] The distance between the first limiting portion 102 and the side wall portion / embedded portion 101 of the extension portion 109 is greater than or equal to the thickness of the side wall of the box body / box cover where the engaging member 2 is located, and the side wall of the box body / box cover where the engaging member 2 is located can be easily inserted into the slot 100; or, the distance between the first limiting portion 102 and the side wall portion / embedded portion 101 of the extension portion 109 is greater than or equal to the thickness of the side wall of the box body / box cover where the engaging member 2 is located, and the side wall of the box body / box cover where the engaging member 2 is located is interference fit to achieve a tight engagement. That is, the space between the first limiting portion 102 and the side wall portion / embedded portion 101 of the extension portion 109 is slightly smaller than the side wall of the packaging box plus the thickness of the engaging member, thereby limiting the relative movement between the box cover 3 and the box body 4. For example, if the thickness of the side wall of the packaging box plus the engaging piece is 4 mm, the thickness between the first limiting portion 102 and the side wall portion of the extension portion 109 / embedded portion 101 can be set to 3.95 mm, for example. The arc structure end of the first limiting portion 102 located at the notch can facilitate the insertion of the side wall and the engaging piece, and then squeeze the side wall of the packaging box during the insertion process, so that the side wall of the packaging box and the engaging piece are tightly connected in the slot 100. In the engaged state, the amount of the first engaging portion 104 buckled into the engaging slot 203 is greater than or equal to half of the thickness of the side wall of the packaging box, thereby achieving reliable fixation.

[0113] like Fig.15 and Fig.16 As shown in FIG. 1 , when the box body 4 and the box cover 3 are closed, the buckle body 1 and the engaging member 2 are engaged with each other. The box cover 3 is inserted into the buckle body 1 along the guide portion 106. Figure 1 The second clamping part 103 and the first clamping part 104 are limited by the guide part 106 in the left and right directions, and are limited by the side wall of the first limiting part 102 and the extension part 109 in the up and down directions, and finally abut the groove bottom part of the extension part 109 to complete the clamping process. During the clamping process, the second clamping part 103 and the first clamping part 104 will be elastically deformed and fall into the clamping groove 203 of the clamping member 2. The protruding fixing part 202 of the clamping member 2 is an elastic structure, which will be elastically deformed during the clamping process, and finally the protruding fixing part 202 is accommodated in the second gap 1051. For example, the protruding fixing part 202 is bent and inclined to increase its elasticity and be more tightly limited in the second gap 1051.

[0114] When a counterfeiter tries to pry the lock by inserting a tool such as a steel ruler into the gap of the packaging box, the external tool cannot touch the first clamping part 104 and the second clamping part 103 because the inside of the clamping groove of the clamping body 1 is tightly matched with the box cover and the clamping piece, there is no moving gap, and the two sides are restricted by the guide part 106. At the same time, the protruding fixing part 202 is also accommodated in the second gap 1051, further enhancing the anti-deformation ability of the box cover.

[0115] At the same time, when the box cover is lifted up, the edge of the clamping groove 203 of the clamping member 2 will enter the first gap 1041 and be limited by the first clamping portion 104, and the ends of the first clamping portion 104 and the second clamping portion 103 will be embedded in the multilayer board of the box cover. Without damaging the cover body, anti-counterfeiting buckle and other structures, or without external force causing permanent deformation of the shell, the packaging box is difficult to be opened, thereby protecting the wine box well.
