Description

Technical Field

[0001] The utility model relates to the technical field of packaging, and particularly relates to a packing box with an embedded lock. Background Art

[0002] During the transportation of goods, it is necessary to use a packing box to seal them. During transportation, in order to ensure the safety of the goods, a lock is used to seal the packing box to ensure the safety of the goods.

[0003] Regarding the above related technologies, the inventor believes that there are the following defects: when the existing lock of the packing box is used, the lock will protrude outside the packing box, which affects the overall aesthetics of the packing box. In addition, the lock protruding outside the packing box will be scratched during transportation, thus affecting the service life of the device. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides a packing box with an embedded lock.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions:

[0006] A packing box with an embedded lock includes a packing box body with an open upper end. A packing box cover is rotatably arranged on the upper surface of the packing box body. The packing box body and the packing box cover are rotatable with each other through a hinge. A handheld part is fixedly arranged on the side wall of the packing box body. The handheld part and the packing box body are fixedly connected by screws. The handheld part is a leather handheld part. A locking device for locking the packing box body and the packing box cover is jointly arranged on the packing box body and the packing box cover.

[0007] By adopting the above technical solutions, when a staff member needs to use the packing box, items can be stored through the packing box body. Subsequently, the packing box cover is closed. During this process, the staff member needs to activate the locking device to seal the packing box. Subsequently, the staff member lifts the packing box through the handheld part. During this process, the locking device is of an embedded design, which reduces the probability of being scratched during transportation and thus reduces the service life.

[0008] Furthermore, a first installation groove is formed on the side wall of the packing box body, and a second installation groove is formed on the side wall of the packing box cover. The locking device includes a lock catch fixedly arranged on the inner wall of the second installation groove, a rotating seat fixedly arranged on the inner wall of the second installation groove, a rotating plate rotatably arranged on the rotating seat, and a locking plate slidably arranged in the rotating plate. The lock catch and the locking plate are matched with each other.

[0009] By adopting the above technical solution, when the staff needs to seal the packing box, the staff needs to move the locking plate downward, so that the locking plate abuts against the locking buckle, thereby sealing the packing box. In addition, when the staff needs to open the packing box, the staff needs to slide the locking plate upward, so that the locking plate is separated from the locking buckle. Subsequently, the staff rotates the rotating plate to open the packing box cover. During this process, the locking device is located in the first installation groove and the second installation groove, thereby reducing the probability of scratching during transportation and thus reducing the service life.

[0010] Furthermore, a fixing groove is formed on the side wall of the locking plate, a bolt is threadedly penetrated through the side wall of the rotating plate, a fixing block is rotatably arranged on the side wall of the bolt close to the fixing groove, a first inclined surface is formed on the edge where the inner wall of the fixing groove intersects with the side wall of the locking plate close to the fixing block, and a second inclined surface is formed on the edge where the side wall of the fixing block close to the locking plate intersects with one of the adjacent side walls.

[0011] By adopting the above technical solution, when the staff needs to slide the locking plate downward, the staff needs to rotate the bolt, so that the bolt moves towards the locking plate, thereby making the fixing block move towards the locking plate under the action of the bolt, so that the first inclined surface abuts against the second inclined surface, so that the locking plate slides downward under the action of the fixing block, so that the locking plate abuts against the locking buckle. During this process, the bolt has good stability, thereby reducing the probability that the locking plate and the locking buckle are separated when subjected to external forces, thus improving the stability of the device.

[0012] Furthermore, a first spring is fixedly arranged on the inner wall of the rotating plate, and the other end of the first spring is fixedly arranged on the side wall of the locking plate.

[0013] By adopting the above technical solution, when the locking plate is separated from the locking buckle, the locking plate slides upward under the action of the first spring. During this process, the first spring reduces the difficulty for the staff to slide the locking plate, thus reducing the working difficulty of the staff.

[0014] Furthermore, two symmetrically arranged rotating grooves are formed on the outer wall of the bolt, rotating rods are rotatably arranged in both of the two rotating grooves, and a rotating member is fixedly arranged on the side walls of the two rotating rods away from each other.

[0015] By adopting the above technical solution, when the staff needs to rotate the bolt, the staff needs to rotate the rotating member, so that the rotating rod rotates, so that the rotating member is in a horizontal state. Subsequently, the staff rotates the rotating member, so that the bolt rotates under the action of the rotating member, thus reducing the difficulty for the staff to rotate the bolt, and thus reducing the working difficulty of the staff.

[0016] Furthermore, rubber rings are sleeved on the outer walls of both of the rotating rods.

[0017] By adopting the above technical solution, rubber has good elasticity. The rubber ring made of rubber material improves the upper limit of the maximum static friction force between the rotating rod and the rotating groove, thereby reducing the probability of the rotating rod rotating when subjected to an external force, and further improving the stability of the device.

[0018] Furthermore, a mounting plate is fixedly arranged on the side wall of the rotating seat. A through hole is penetrated through the side wall of the mounting plate. A third mounting groove is penetrated through the side wall of the rotating member. The mounting plate and the third mounting groove are mutually matched.

[0019] By adopting the above technical solution, when the staff rotates the rotating member to make the rotating member perpendicular to the bolt, the mounting plate and the third mounting groove are mutually matched. Subsequently, the staff can lock the packaging box through the through hole. At this time, the staff cannot rotate the rotating member, and thus cannot rotate the bolt, thereby improving the safety of the device.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. In this application, when the staff needs to use the packaging box, items can be stored through the packaging box body. Subsequently, close the packaging box cover. During this process, the staff needs to start the locking device to seal the packaging box. Subsequently, the staff lifts the packaging box through the handheld part. During this process, the locking device is of an inlaid design, thereby reducing the probability of scratching during transportation and thus reducing the service life;

[0022] 2. In this application, when the staff needs to seal the packaging box, the staff needs to move the locking plate downward, so that the locking plate abuts against the locking buckle, thereby sealing the packaging box. In addition, when the staff needs to open the packaging box, the staff needs to slide the locking plate upward, so that the locking plate is separated from the locking buckle. Subsequently, the staff rotates the rotating plate to open the packaging box cover. During this process, the locking device is located in the first mounting groove and the second mounting groove, thereby reducing the probability of scratching during transportation and thus reducing the service life;

[0023] 3. In this application, when the staff needs to slide the locking plate downward, the staff needs to rotate the bolt, so that the bolt moves in the direction close to the locking plate, so that the fixed block moves in the direction close to the locking plate under the action of the bolt, so that the first inclined surface abuts against the second inclined surface, so that the locking plate slides downward under the action of the fixed block, so that the locking plate abuts against the locking buckle. During this process, the bolt has good stability, thereby reducing the probability of the locking plate and the locking buckle separating from each other when subjected to an external force, and thus improving the stability of the device.

Detailed Embodiment

[0029] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0030] As Figures 1-4 shown, an embodiment of the present application discloses a packing box with an embedded lock, including a packing box main body 1, a packing box cover 11, a hand-held part 12, a screw 13, a locking device 3, a bolt 4, a fixing block 41, a first spring 5, a rotating rod 6, and a rotating member 61. The packing box main body 1 is a cuboid-shaped structure with an open upper end, the packing box cover 11 is a cuboid-shaped structure with an open lower end, and the packing box main body 1 and the packing box cover 11 are rotatable with each other through a hinge. The hand-held part 12 is fixedly arranged on the side wall of the packing box main body 1, the hand-held part 12 and the packing box main body 1 are fixed to each other through a screw 13, and the hand-held part 12 is a leather hand-held part 12

[0031] When the staff needs to use the packing box, items can be stored through the packing box body 1. Subsequently, close the packing box lid 11. During this process, the staff needs to activate the locking device 3 to seal the packing box. Subsequently, the staff lifts the packing box through the holding part 12. During this process, the locking device 3 is of an inlaid design, thereby reducing the probability of scratching during transportation and thus reducing the service life.

[0032] A first installation groove 2 is provided on the side wall of the packing box body 1, and a second installation groove 21 is provided on the side wall of the packing box lid 11. The locking device 3 is arranged on the packing box body 1 and the packing box lid 11 for locking the packing box body 1 and the packing box lid 11. The locking device 3 includes a lock catch 31, a rotating seat 32, a rotating plate 33 and a locking plate 34. The lock catch 31 is fixedly arranged on the inner wall of the second installation groove 21, the rotating seat 32 is fixedly arranged on the inner wall of the second installation groove 21, the rotating plate 33 is rotatably arranged on the rotating seat 32, the locking plate 34 is slidably arranged in the rotating plate 33, and the lock catch 31 and the locking plate 34 match each other.

[0033] When the staff needs to seal the packing box, the staff needs to move the locking plate 34 downward, so that the locking plate 34 abuts against the lock catch 31, thereby sealing the packing box. In addition, when the staff needs to open the packing box, the staff needs to slide the locking plate 34 upward, so that the locking plate 34 is separated from the lock catch 31. Subsequently, the staff rotates the rotating plate 33 to open the packing box lid 11. During this process, the locking device 3 is located in the first installation groove 2 and the second installation groove 21, thereby reducing the probability of scratching during transportation and thus reducing the service life.

[0034] A fixing groove 22 is provided on the side wall of the locking plate 34. The bolt 4 is threadedly penetrated through the side wall of the rotating plate 33, and its axis is horizontal. The fixing block 41 is rotatably arranged on the side wall of the bolt 4 close to the fixing groove 22. A first inclined surface 42 is provided on the edge where the inner wall of the fixing groove 22 intersects with the side wall of the locking plate 34 close to the fixing block 41, and a second inclined surface 43 is provided on the edge where the side wall of the fixing block 41 close to the locking plate 34 intersects with one of the adjacent side walls.

[0035] When the staff needs to slide the locking plate 34 downward, the staff needs to rotate the bolt 4, so that the bolt 4 moves towards the locking plate 34, so that the fixing block 41 moves towards the locking plate 34 under the action of the bolt 4, so that the first inclined surface 42 abuts against the second inclined surface 43, so that the locking plate 34 slides downward under the action of the fixing block 41, so that the locking plate 34 abuts against the lock catch 31. During this process, the bolt 4 has good stability, thereby reducing the probability of the locking plate 34 and the lock catch 31 being separated when subjected to external forces, and thus improving the stability of the device.

[0036] One end of the first spring 5 is fixedly arranged on the inner wall of the rotating plate 33, and the other end of the first spring 5 is fixedly arranged on the side wall of the locking plate 34.

[0037] When the locking plate 34 is separated from the locking buckle 31, the locking plate 34 slides upward under the action of the first spring 5. During this process, the first spring 5 reduces the difficulty for the staff to slide the locking plate 34, thereby reducing the work difficulty of the staff.

[0038] Two symmetrically arranged rotating grooves 23 are formed on the outer wall of the bolt 4. The rotating rod 6 has a round rod structure with a horizontal axis. There are two rotating rods 6 which are respectively rotatably arranged in the two rotating grooves 23, and the rotating member 61 is fixedly arranged on the side walls of the two rotating rods 6 away from each other.

[0039] When the staff needs to rotate the bolt 4, the staff needs to rotate the rotating member 61, thereby rotating the rotating rod 6 and making the rotating member 61 in a horizontal state. Subsequently, the staff rotates the rotating member 61, and then the bolt 4 rotates under the action of the rotating member 61, thereby reducing the difficulty for the staff to rotate the bolt 4 and further reducing the work difficulty of the staff.

[0040] In order to improve the stability of the device, rubber rings 7 are sleeved on the outer walls of the two rotating rods 6. Rubber has good elasticity. The rubber ring 7 made of rubber material improves the upper limit of the maximum static friction force between the rotating rod 6 and the rotating groove 23, thereby reducing the probability of the rotating rod 6 rotating when subjected to an external force, and further improving the stability of the device.

[0041] In order to improve the safety of the device, a mounting plate 8 is fixedly arranged on the side wall of the rotating seat 32. A through hole 81 is formed through the side wall of the mounting plate 8, and a third mounting groove 82 is formed through the side wall of the rotating member 61. The mounting plate 8 and the third mounting groove 82 are mutually matched. When the staff rotates the rotating member 61 to make the rotating member 61 perpendicular to the bolt 4, the mounting plate 8 and the third mounting groove 82 are mutually matched. Subsequently, the staff can lock the packaging box through the through hole 81. At this time, the staff cannot rotate the rotating member 61, and thus cannot rotate the bolt 4, thereby improving the safety of the device.

[0042] The working principle of the packaging box with an embedded lock in this embodiment is as follows:

[0043] When the staff needs to use the packing box, items can be stored through the packing box body 1. Subsequently, close the packing box cover 11. During this process, when the staff needs to seal the packing box, the staff needs to move the locking plate 34 downward, so that the locking plate 34 abuts against the locking buckle 31, thereby sealing the packing box. In addition, when the staff needs to open the packing box, the staff needs to slide the locking plate 34 upward, so that the locking plate 34 is separated from the locking buckle 31. Subsequently, the staff rotates the rotating plate 33 to open the packing box cover 11. During this process, the staff lifts the packing box through the handheld part 12. During this process, the locking device 3 is of an embedded design, thereby reducing the probability of scratching during transportation and thus reducing the service life.
