In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0047] In the packaging industry, in order to facilitate the packaging of large and heavy products, upper and lower card sleeve or wrap-around packaging is used. Such packaging needs to be locked with a lock so that the outer boxes of the packaging can be combined together to achieve a closed integrated structure. In order to cater to the trend and trend of plastic removal in packaging, paper locks came into being. At present, the common paper locks on the market need to go through a complex folding and bonding process to be formed, and the folding work needs to be done manually, which consumes a lot of manpower and energy, and increases the cost of use.

[0048] To solve the above problems, see Figures 1 to 13The present embodiment provides a lock. The lock includes a main body 1 and a lock unit 2. The main body 1 includes a baffle 11 with a square through hole 111 in the middle. The square through hole 111 of the baffle 11 is connected to locking plates 12 on two opposite sides along the first direction. The locking plate 12 is provided with a locking groove 121. The two ends of the baffle 11 along the second direction are respectively connected to a first adhesive plate 13 and a second adhesive plate 14. The first adhesive plate 13 and the second adhesive plate 14 can be folded and fixedly connected to the baffle 11. The first adhesive plate 13 and the second adhesive plate 14 are connected to a support plate assembly 15 on one side away from the baffle 11. The two support plate assemblies 15 and the two locking plates 12 can be folded to form a containing frame. The lock unit 2 includes two lock structures, which include a connected fixed plate assembly 211 and a shielding plate assembly 212. The fixed plate assembly 211 is provided with locking protrusions 213 at both ends along the first direction. The surfaces of the two fixed plate assemblies 211 are fixedly connected. The two shielding plate assemblies 212 are folded in a direction away from each other and are fixedly connected to the support plate assembly 15. The two locking protrusions 213 can be respectively accommodated in the two locking grooves 121, so that the lock is in the first state, or the two locking protrusions 213 can be respectively removed from the two locking grooves 121 and move in a direction away from the accommodating frame, so that the lock is in the second state. The first direction is perpendicular to the second direction, the first state is the locked state, and the second state is the unlocked state.

[0049] The process of folding and forming the main body 1 is as follows Figure 4 As shown, firstly, the first adhesive plate 13 and the second adhesive plate 14 are folded toward the direction of the baffle 11, so that the first adhesive plate 13 and the second adhesive plate 14 are in contact with the surface of the baffle 11 and both are fixedly connected to the baffle 11. At this time, the support plate assembly 15 connected to the first adhesive plate 13 and the second adhesive plate 14 is folded in the direction that can pass through the through hole, and the first locking plate 12 and the second locking plate 12 are also folded in the direction that can pass through the through hole. After folding, the two support plate assemblies 15 and the two locking plates 12 form a containing frame.

[0050] In some embodiments, Figure 2 As shown, the locking unit 2 is designed as an integral unit, that is, the fixing plate components 211 of the two locking structures are connected. The process of folding and forming the locking unit 2 is as follows: Figure 5 As shown, the shielding plate assembly 212 is first folded into shape, and then the two fixing plate assemblies 211 are folded toward each other and fixed, and the two shielding plate assemblies 212 are folded away from each other, so that the entire locking unit 2 is in a T shape. Figure 8As shown, the two shielding plate assemblies 212 are fixedly connected to the support plate assemblies 15 respectively. At this time, the two fixed plate assemblies 211 are located in the accommodating frame, and the locking protrusion 213 is accommodated in the locking groove 121, so that the lock is in the first state; the locking protrusion 213 is disengaged from the locking groove 121 and the fixed plate assembly 211 is pulled to move in the direction away from the accommodating frame, so that the lock is in the second state.

[0051] When in use, place the accommodating frame into the first locking mounting hole and the second locking mounting hole of the outer box and the inner box. Fig.10 , Fig.11 As shown, when the lock is in the first state, the two shielding plate assemblies 212 abut against the inner box body, the baffle 11 abuts against the outer box body, and the two locking protrusions 213 are located in the locking grooves 121, that is, the outer box body and the inner box body are locked; Fig.12 , Fig.13 As shown, when unlocking, the locking protrusion 213 is disengaged from the locking groove 121 and the fixing plate assembly 211 is pulled to move in a direction away from the accommodating frame. At this time, the two shielding plate assemblies 212 and the fixing plate assembly 211 are located in the same plane, and the lock is pulled out from the first lock installation hole and the second lock installation hole of the outer box and the inner box, so that the outer box and the inner box are unlocked. The process of folding and forming the lock is simple, it can be reused, and it is environmentally friendly and durable.

[0052] Preferably, if Figure 1 , Figure 4 , Figure 8 As shown, the support plate assembly 15 includes a first support plate 151 and a second support plate 152 connected to each other, and the second support plate 152 can be folded in a direction away from the square through hole 111. At this time, the first support plate 151 and the second support plate 152 are in an inverted L shape, and the two first support plates 151 and the two locking plates 12 are surrounded to form a containing frame, and the two shielding plate assemblies 212 are respectively fixedly connected to the two second support plates 152. This arrangement makes the connection between the locking unit 2 and the main body 1 more stable.

[0053] Specifically, Figure 2 , Figure 5 As shown, the shielding plate assembly 212 includes a first shielding plate 2121 and a second shielding plate 2122 connected to each other. After being folded, the second shielding plate 2122 can fit with the first shielding plate 2121 and the two are fixedly connected. The shielding plate assembly 212 is a double-layer structure after being folded and formed, and the structure is more stable and not easy to deform. When the lock is used to lock the outer box and the inner box, the lock will not be easily damaged under the action of external force, causing the outer box and the inner box to separate.

[0054] In this embodiment, if Figure 2 , Fig. 9As shown, the fixed plate assembly 211 includes a fixed plate 2111 and movable plates 2112 disposed at both ends of the fixed plate 2111. A locking protrusion 213 is convexly disposed on one side of the movable plate 2112 away from the fixed plate 2111. When the fixed plate assembly 211 is placed in the receiving frame, the distance between the two locking plates 12 is smaller than the length of the fixed plate assembly 211. At this time, the movable plate 2112 and the fixed plate 2111 are at a certain angle to be exactly accommodated in the receiving frame, such as Fig.10 As shown, when the lock needs to be switched to the first state, i.e. locked, the movable plate 2112 is pushed to be level with the movable plate 2112 so that the locking protrusion 213 on the movable plate 2112 enters the locking groove 121 to achieve locking; when the lock needs to be switched to the second state, i.e. unlocked, as shown Fig.12 As shown, pushing the movable plate 2112 to make it at a certain angle with the movable plate 2112 can make the locking protrusion 213 on the movable plate 2112 escape from the locking groove 121 to achieve unlocking. Locking and unlocking only require pushing the movable plate 2112, which is simple and fast to switch, saving time and effort.

[0055] Preferably, if Fig.11 As shown, when the lock is in the first state, the two shielding plate assemblies 212 can cover the opening of the accommodating frame together, so that when the outer box body and the inner box body are locked, the first lock mounting hole and the second lock mounting hole can be covered by the two shielding plate assemblies 212 to achieve a dustproof effect.

[0056] Similarly, if Fig.13 As shown, when the lock is in the second state, the two first support plates 151 can jointly cover the square through hole 111. When the outer box and the inner box are unlocked and the lock is not removed, the first lock installation hole and the second lock installation hole can be covered by the two first support plates 151, thereby achieving a dustproof effect.

[0057] Preferably, the lock further comprises a reinforcing structure 3, which is sleeved on the outer periphery of the receiving frame. The reinforcing structure 3 is used to strengthen the structural strength of the receiving frame, so that it is not easily deformed, and the locking stability of the outer box body and the inner box body is ensured.

[0058] Specifically, Figure 3 As shown, the reinforcement structure 3 includes a reinforcement assembly 31, and the reinforcement assembly 31 includes two reinforcement plates 311 and two first connecting plates 312. The reinforcement plates 311 are provided with avoidance holes 3111. Both ends of a reinforcement plate 311 are connected to the first connecting plates 312, and one connecting plate is connected to another reinforcement plate 311. In the folded reinforcement assembly 31, the two reinforcement plates 311 are opposite to each other, and the two first connecting plates 312 are opposite to each other. Figure 7 As shown, it is sleeved on the outer periphery of the accommodating frame to play a supporting role. At this time, the two avoidance holes 3111 are directly opposite to the two locking grooves 121 one by one.

[0059] Furthermore, if Figure 3 As shown, in order to make the reinforcement structure 3 more stable and less prone to deformation, the reinforcement structure 3 also includes a reinforcement component 32, which includes two reinforcement plates 321 and two second connecting plates 322. Both ends of a reinforcement plate 321 are connected to the second connecting plates 322, one of the second connecting plates 322 is connected to the other reinforcement plate 321, and the other reinforcement plate 321 is connected to the first connecting plate 312. That is, the reinforcement component 31 and the reinforcement component 32 are designed as an integral molding. After folding and molding, the reinforcement component 32 is arranged outside the reinforcement component 31, so that the reinforcement structure 3 is a double-layer structure, which is more stable and less prone to deformation.

[0060] In this embodiment, the main body, the locking unit 2 and the reinforcing structure 3 are all made of corrugated cardboard materials, which are green and environmentally friendly. The fixed connections between the various parts are bonded and fixed with white latex. Figure 1 to Figure 3 The shaded parts in the figure are all glue-coated areas. The molding cost is low and environmentally friendly by gluing, and the appearance of the lock is not affected, which makes it neat and beautiful.

[0061] This embodiment also provides a carton, including an outer box, an inner box and the above-mentioned lock. The outer box includes a first lock mounting hole, the inner box includes a second lock mounting hole, the inner box is sleeved in the outer box and the first lock mounting hole is directly opposite to the second lock mounting hole. This carton separates the inner box from the outer box, and is suitable for heavy product packaging. When in use, the heavy product is placed in the inner box, and then the outer box is sleeved over the heavy product and the inner box. The lock is installed on the outer box and the inner box through the first lock mounting hole on the outer box and the second lock mounting hole on the inner box support. The outer box and the inner box are further locked together by the lock unit 2, that is, the locking connection between the outer box and the inner bottom support is realized.

[0062] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
