Description

Technical Field

[0001] The invention belongs to the technical field of anti-theft buckles for packaging boxes and relates to an adjustable anti-theft lock buckle used in a book-shaped packaging box. Background Art

[0002] The book-shaped box is a paper box structure that operates like opening a book. It can be used to package various products to facilitate the carrying and transportation of products and provide product protection. Due to the more elegant appearance and more prominent protective properties of the book-shaped box, most of the more expensive wines on the market are packaged in this type of box structure. However, many criminals will recycle expensive wine boxes, and the empty wine boxes will be recycled and reused by other wineries, causing wine boxes to be mixed into the market even if they contain non-original authentic wines. This not only disrupts the normal market and trading order, thereby damaging the interests of the original manufacturers, but also the interests of consumers.

[0003] In order to make their own products have a good brand effect and prevent counterfeit and inferior products from using the manufacturer's wine box packaging to enter the market and damage the interests of the original manufacturer; most of the packaging box structures on the market currently use a disposable anti-theft buckle structure to protect their own products. The technical feature of this type of anti-theft buckle structure is that after the box lid is closed, when the box lid is opened again, the original lock structure will be destroyed, so that the box body cannot be used for secondary packaging, which can effectively prevent counterfeit and inferior products;

[0004] However, when this type of anti-theft buckle structure is applied to the book-shaped box structure, since the manufacturer of the packaging box is generally not the winery itself, after the book-shaped box is produced, there will be a transportation process between the packaging box manufacturer and the winery. During this process, due to the presence of the anti-theft buckle, the lid of the book-shaped box cannot be closed. Therefore, the book-shaped box can only be transported with the lid open. Not only is it easy for dust to accumulate inside the book-shaped box and foreign matter to enter, the open and outward-extending lid will also cause the overall volume of the book-shaped box to increase, the transportation space occupied will increase, and the transportation cost will increase. Even during the transportation process, the relatively weak connection between the book-shaped box and the lid may break, causing the lid to fall off and the book-shaped box to be scrapped. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] An adjustable anti-theft lock for a book-shaped packaging box comprises a lock hole fastener and a lock column fastener. The lock hole fastener comprises a lock hole base plate, the lock hole base plate being provided with a lock hole extending therethrough; a movable lock plate being slidably mounted on the lock hole base plate, the movable lock plate being provided with a movable through-hole and a locking hole at the front and rear ends; a lock assembly being provided at the edge of the locking hole; and the movable through-hole and the locking hole being aligned with the lock hole by sliding the movable lock plate.

[0007] The lock post fastener comprises a lock post base plate, on which a lock pin extending outward is provided; when the lock pin is inserted into the locking buckle hole, the lock pin is locked inside by the lock assembly so that it cannot fall out.

[0008] As a further embodiment of the present invention, the lock assembly comprises a plurality of lock bodies, which are inclined from bottom to top and converge toward the center of the locking hole; a snap pin is formed on the top of the lock body and extends toward the center of the locking hole; the lower end surface of the snap pin is an upwardly inclined guide surface, and the upper end surface of the snap pin is a horizontal abutment surface;

[0009] A plurality of sheet-like locking edges are formed on the lock pin on the lock cylinder base plate, and a locking slot for the buckle pin to be inserted is formed between two adjacent upper and lower locking edges.

[0010] As a further solution of the present invention: a pair of parallel slide rail seats are formed on the lock hole base plate, and the inner end surface of the slide rail seat is formed with a slide rail groove arranged along the length direction thereof;

[0011] Sliding edges that match the slide rail grooves are formed on both sides of the movable lock plate. The sliding edges slide into the slide rail grooves to achieve sliding cooperation between the movable lock plate and the lock hole base plate.

[0012] As a further solution of the present invention: two positioning buckle holes arranged front and back are formed on the slide rail seat;

[0013] A positioning convex point corresponding to the positioning buckle hole is formed on the sliding edge of the movable locking plate; the front end of the positioning convex point is a guide sliding inclined surface, and the rear end is a flat blocking surface.

[0014] As a further solution of the present invention: a pair of parallel guide rails are further formed on the keyhole base plate, and the guide rails are arranged between the two rail seats and along the length direction of the rail seats;

[0015] The lower end of the movable lock plate is formed with a guide groove corresponding to the guide rail; when the movable lock plate slides onto the lock hole base plate, the guide rail will align and enter the guide groove.

[0016] The beneficial effects of the present invention are as follows: a movable locking plate is provided on the basis of the lock hole fastener and the lock column fastener, and the movable perforation and the locking buckle hole can be aligned with the lock buckle through hole respectively by providing a slidable movable locking plate; the lock hole fastener and the lock column fastener are matched with each other in an unrestricted manner, so that the book-shaped box can be transported in a closed state; after the product is placed in the book-shaped box, the locking buckle hole is aligned with the lock buckle through hole by sliding the movable locking plate, and then the book-shaped box is closed, so that the lock hole fastener and the lock column fastener are locked in a limited position, thereby achieving an anti-theft effect;

[0017] The movable lock plate structure can effectively solve the problem that the lid of the book-shaped box with the existing anti-theft buckle structure cannot be closed for transportation, causing inconvenience in transportation; the overall anti-theft buckle structure is reasonable and stable, which is more in line with current market application needs and is easier to promote and apply.

[0027] The present invention provides Figures 1 to 4 In an embodiment of the present invention, an adjustable anti-theft lock buckle used in a book-shaped packaging box includes: a lock hole fastener 1 and a lock column fastener 3, which are used in a box body 41 of a book-shaped box 4;

[0028] The keyhole fastener 1 comprises a keyhole base plate 10, which is provided with a through-hole 11; a movable lock plate 2 is slidably mounted on the keyhole base plate 10, and the movable lock plate 2 is provided with a movable through-hole 23 and a locking hole 21 at the front and rear ends; a locking assembly 22 is provided at the edge of the locking hole 21; the movable through-hole 23 and the locking hole 21 are aligned with the through-hole 11 by sliding the movable lock plate 2;

[0029] The lock post fastener 3 comprises: a lock post base plate 30, on which a lock post pin 31 extending outward is provided;

[0030] When the lock pin 31 passes through the movable through hole 23 and the lock through hole 11, it will not be restricted and can be freely inserted and removed;

[0031] When the locking pin 31 is inserted into the locking buckle hole 21, the locking pin 31 is locked inside by the locking assembly 22, so that it cannot fall out. If the locking hole fastener 1 and the lock column fastener 3 are forcibly separated, the locking hole fastener 1 and the lock column fastener 3 will be damaged, making it impossible to lock again. After the box body 41 is opened once, the box body 41 cannot be restored, preventing the box body 41 from being repackaged and reused, effectively eliminating counterfeit and shoddy products.

[0032] like Figure 5As shown, the box body 41 of the book-shaped box 4 includes: a box body 41, the upper end of the box body 41 is open, and a box cover 42 is formed at the opening position, one side of the box cover 42 is connected to the box body 41, and the box cover 42 can be folded along the side to cover the opening of the box body 41; the other side of the box cover 42 is also provided with a front locking plate 43, when the box cover 42 covers the opening of the box body 41, the front locking plate 43 covers the front end surface position of the box body 41;

[0033] During use, the lock hole fastener 1 is arranged on the front face of the box body 41, and the lock column fastener 3 is arranged on the front lock plate 43. After the box cover 42 is folded over and covered on the box body 41, the lock pin 31 in the lock column fastener 3 will penetrate into the lock through hole 11 to achieve engagement;

[0034] After the production of the book-shaped box 4 is completed, during transportation, in order to enable the book-shaped box 4 to be transported in a closed state, the movable perforation 23 in the movable locking plate 2 on the lock hole fastener 1 is aligned with the lock buckle through hole 11; the lock hole fastener 1 and the lock column fastener 3 are matched without limiting the position, so that the book-shaped box 4 can be transported in a closed state; after the product is placed in the book-shaped box 4, the locking buckle hole 21 is aligned with the lock buckle through hole 11 by sliding the movable locking plate 2, and then the book-shaped box 4 is closed, so that the lock hole fastener 1 and the lock column fastener 3 are matched with each other in a limited position, thereby achieving an anti-theft effect.

[0035] Furthermore, the lock assembly 22 is composed of a plurality of lock bodies 221, which are inclined from bottom to top and converge toward the center of the locking buckle hole 21. The top of the lock body 221 is formed with a snap pin 222 extending toward the center of the locking buckle hole 21. The lower end surface of the snap pin 222 is an upwardly inclined inclined guide surface 224, and the upper end surface of the snap pin 222 is a horizontal abutment surface 223.

[0036] The locking pin 31 on the lock cylinder base plate 30 is formed with a plurality of sheet-like locking edges 32, and a locking slot 33 for the buckle pin 222 to be inserted is formed between two adjacent locking edges 32.

[0037] When the lock pin 31 is inserted into the locking buckle hole 21, the inclined guide surface 224 on the buckle tip pin 222 can make the lock pin 31 smoothly inserted into the locking buckle hole 21 and smoothly pass through the lock assembly 22. The buckle tip pin 222 will be inserted into the corresponding locking groove 33 to complete the lock assembly; when it needs to be opened again, the abutting surface 223 of the buckle tip pin 222 will have an abutting effect with the locking edge piece 32. If the lock hole fastener 1 and the lock column fastener 3 are forcibly separated, the buckle tip pin 222 and the locking edge piece 32 will be broken and damaged accordingly, so that the limiting resistance between them disappears, so that after the box body 41 is opened once, the lock hole fastener 1 cannot be locked with the lock column fastener 3 again.

[0038] Furthermore, a pair of parallel rail seats 12 are formed on the keyhole base plate 10, and a rail groove 122 is formed on the inner end surface of the rail seat 12 along its length direction;

[0039] The movable lock plate 2 is formed with sliding edges 24 on both sides thereof, which cooperate with the slide rail groove 122. The sliding edges 24 slide into the slide rail groove 122 to achieve sliding cooperation between the movable lock plate 2 and the lock hole base plate 10.

[0040] In order to make the movable lock plate 2 more stable during the sliding process and prevent it from shaking left and right, a pair of parallel guide rails 13 are formed on the lock hole base plate 10. The guide rails 13 are arranged between the two rail seats 12 and along the length direction of the rail seats 12.

[0041] The lower end of the movable lock plate 2 is formed with a guide groove 25 corresponding to the guide rail 13; when the movable lock plate 2 slides onto the lock hole base plate 10, the guide rail 13 will align and enter the guide groove 25, achieving the effect of positioning and guiding sliding during the sliding process.

[0042] Furthermore, the rail bar seat 12 is formed with two positioning buckle holes 121 arranged front and back;

[0043] A positioning protrusion 241 corresponding to the positioning buckle hole 121 is formed on the sliding edge 24 of the movable locking plate 2; when the positioning protrusion 241 is buckled into the first positioning buckle hole 121, the movable through hole 23 is aligned with the locking through hole 11; when the positioning protrusion 241 is buckled into the second positioning buckle hole 121, the locking buckle hole 21 is aligned with the locking through hole 11;

[0044] Furthermore, the front end of the positioning protrusion 241 is a guide sliding inclined surface, and the rear end is a flat blocking surface, so that the movable locking plate 2 as a whole can only slide forward.

[0045] It should also be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
