Description

Technical Field

[0001] The present application belongs to the technical field of security inspection equipment, and more specifically, relates to an automatic retractable luggage packing lock. Background Art

[0002] Currently, after landing, foreign passengers must pass through border inspection before entering China. If a passenger is carrying dangerous goods, the risk interception system will detect them and separate them from other normal luggage. During customs inspection, luggage containing dangerous goods must be identified and locked to prevent passengers from opening and removing them. Therefore, a lock is required, and only customs officials can unlock the bag for inspection.

[0003] Existing technical solutions involve wrapping sensor chips around passengers' luggage or bags with tape. This tape cannot be recycled, requiring constant replenishment, a cumbersome and inefficient process. The tape can easily be cut by passengers themselves, who then open their luggage and remove dangerous items, defeating the purpose of intercepting the risk. Furthermore, when the tape is wrapped around the luggage, it adheres to the surface and may damage the luggage when removed. Summary of the Invention

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0025] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0027] Please also refer to Figures 1 to 2 The automatic retractable luggage packing lock 100 provided in an embodiment of the present application is now described. The automatic retractable luggage packing lock 100 includes: a dual wheel assembly 10, a wrapping belt 20, and a one-way locking mechanism 30.

[0028] Specifically, the dual-wheel assembly 10 includes a first synchronous wheel 11, a second synchronous wheel 12, a synchronous belt 13 and a spring assembly 14. The synchronous belt 13 is wound around the first synchronous wheel 11 and the second synchronous wheel 12 at the same time. The first synchronous wheel 11 is fixedly connected to a ratchet 15, and the second synchronous wheel 12 is fixedly connected to an external gear 16. The spring assembly 14 is engaged with the second synchronous wheel 12 for transmission.

[0029] One end of the winding belt 20 is wound around the synchronous belt 13 , and the other end is connected to a lock buckle 21 . The lock buckle 21 can be inserted into the one-way locking mechanism 30 , so that the one-way locking mechanism 30 limits the one-way rotation of the ratchet 15 .

[0030] It can be understood that the dual-wheel assembly 10 is composed of the first synchronous wheel 11 and the second synchronous wheel 12, which jointly drive the synchronous belt 13. Since one end of the winding belt 20 is wound around the synchronous belt 13, the storage capacity of the winding belt 20 can be increased in a limited space.

[0031] For example, in public places such as customs and airports, upon discovering suspicious luggage, the automatically retractable luggage packing lock 100 can immediately seal the suspected luggage. Specifically, the lock buckle 21 can be pulled manually or through automated equipment. The lock buckle 21 causes the wrapping belt 20 to extend from the dual-wheel assembly 10. At this time, the spring assembly 14 is compressed. After the wrapping belt 20 wraps around the suspected luggage once, the lock buckle 21 inserts into the one-way locking mechanism 30. The one-way locking mechanism 30 restricts the ratchet wheel 15 from rotating in one direction, so that the wrapping belt 20 can only contract, not extend. Therefore, under the action of the spring assembly 14, the wrapping belt 20 begins to tighten, locking the luggage tighter and tighter.

[0032] In addition, if the winding belt 20 needs to be tightened for a long length, the external gear 16 can be rotated manually or through automated equipment for quick tightening. The external gear 16 can drive the second synchronous wheel 12 to rotate, thereby accelerating the tightening speed.

[0033] It is understood that the outer shell structure is concealed in this embodiment to illustrate the internal structure of the automatic retractable luggage packing lock 100 of the present application. The automatic retractable luggage packing lock 100 can also be equipped with a location tracker, which can track the luggage in real time to prevent loss. Security checks are typically conducted at the entrance of public places using X-ray equipment. If suspicious luggage is found, staff will immediately lock the luggage and the passenger, accompanied by security personnel or on their own, will proceed to the security inspection room for further unpacking and inspection.

[0034] During unpacking and inspection, staff unlock the one-way locking mechanism 30 with a secret key, removing the lock 21 from the one-way locking mechanism 30. This allows the baggage to be opened and the security check completed. This prevents suspicious baggage from being maliciously opened or swapped during transportation. Equipped with a location tracker, the baggage can be tracked, improving security inspection efficiency and combating crime.

[0035] It is worth mentioning that the ratchet 15 is a gear with a rigid toothed surface or friction surface on the outer or inner edge. It is pushed by the pawl to perform stepping motion. The characteristic of this meshing motion is that the ratchet 15 can only rotate in one direction and cannot reverse. In the present application, the unidirectional rotation of the ratchet 15 is controlled by the one-way locking mechanism 30, that is, when the lock buckle 21 is inserted into the one-way locking mechanism 30, the ratchet 15 rotates in one direction, causing the synchronous belt 13 to be tightened. When the lock buckle 21 is pulled out of the one-way locking mechanism 30, the ratchet 15 can rotate in both directions, so that the sending and receiving of the synchronous belt 13 is not restricted.

[0036] Compared with the prior art, the automatic retractable luggage packing lock 100 provided in this application utilizes the first and second synchronous wheels 11 and 12 to jointly drive the synchronous belt 13, thereby increasing the storage capacity of the winding belt 20 within a limited space. The spring assembly 14 provides the winding belt 20 with an automatic tightening function, and the external gear 16 assists in rapid tightening. The lock buckle 21 can be inserted into the one-way locking mechanism 30, so that the one-way locking mechanism 30 restricts the ratchet wheel 15 from rotating in one direction. This prevents suspicious luggage from being maliciously opened or swapped during transportation, thereby improving security inspection efficiency and the reliability of risk interception. The automatic retractable luggage packing lock 100 is reusable, environmentally friendly, and does not damage the appearance of passenger luggage.

[0037] In another embodiment of this application, please refer to Figures 3 to 5 The one-way locking mechanism 30 includes a fixed frame 31, a movable frame 32, a compression lock 33 and a limit block 34. The fixed frame 31 is provided with a gantry frame 311 and a socket frame 312. The bottom surface of the socket frame 312 is provided with a movable hole 313 and the side surface is provided with a sliding hole 314. The limit block 34 is slidably set in the sliding hole 314, and a first reset elastic member 341 is provided between the limit block 34 and the fixed frame 31. The movable frame 32 is movably set in the fixed frame 31 and is provided with a tongue 321. The tongue 321 is located in the movable hole 313. A second reset elastic member 322 is provided between the movable frame 32 and the socket frame 312. The compression lock 33 is fixed on the gantry frame 311 and the output end is connected to the movable frame 32.

[0038] Among them, a card hole 211 is provided on the lock buckle 21, and the lock buckle 21 can be inserted into the socket frame 312, so that the tongue 321 is locked in the card hole 211, and pushes the limit block 34 to limit the one-way rotation of the ratchet 15; the compression lock 33 can press down the movable frame 32, so that the lock buckle 21 pops out of the socket frame 312, and the limit block 34 is reset.

[0039] It can be understood that when the lock buckle 21 begins to be inserted into the socket frame 312, the tongue 321 is squeezed and pressed down together with the entire movable frame 32. Since a second reset elastic member 322 is provided between the movable frame 32 and the socket frame 312, the second reset elastic member 322 will be compressed.

[0040] When the lock buckle 21 is fully inserted into the socket frame 312, the internal force of the second return elastic member 322 causes the tongue 321 to snap into the latch hole 211 of the lock buckle 21, and the movable frame 32 rises. At the same time, the lock buckle 21 pushes the limit block 34 to clamp the ratchet 15, and the first return elastic member 341 is also compressed. When the ratchet 15 rotates clockwise to tighten the winding belt 20, the first return elastic member 341 continues to be compressed, so the ratchet 15 can rotate clockwise to tighten the winding belt 20. However, when the ratchet 15 rotates counterclockwise, the force applied to the limit block 34 is inconsistent with the direction of the spring force, so the ratchet 15 will be stuck, resulting in the ratchet 15 being able to rotate only in one direction.

[0041] When the compression lock 33 presses down the movable frame 32, the movable frame 32 is pressed down, the second reset elastic member 322 is compressed, the tongue 321 disengages from the card hole 211, and the lock buckle 21 resets the limit block 34 under the action of the first reset elastic member 341. The limit block 34 pushes the lock buckle 21 out of the socket frame 312, completing the unlocking action, and the ratchet 15 can rotate in both directions.

[0042] It is worth mentioning that the first resetting elastic member 341 and the second resetting elastic member 322 can be coil springs.

[0043] In another embodiment of this application, please refer to Figures 3 to 5 The protruding tongue 321 is provided with an inclined surface structure 3211 , so that when the lock buckle 21 is inserted into the socket frame 312 , the protruding tongue 321 can be pressed down by the inclined surface structure 3211 .

[0044] It can be understood that, through the inclined structure 3211, when the lock buckle 21 is inserted into the socket frame 312, the tongue 321 can be pressed down by the inclined structure 3211, which can reduce the force required when inserting the lock buckle 21, facilitate locking, and improve convenience.

[0045] In another embodiment of the present application, the compression lock 33 includes a motor and a screw rod, the output end of the motor is connected to the screw rod, and the screw rod is in contact with the top surface of the movable frame 32.

[0046] It is understandable that the motor can drive the screw rod to extend or shorten. When the screw rod extends, the movable frame 32 is pressed down. When the screw rod contracts, the movable frame 32 rises under the action of the internal force of the spring.

[0047] In another embodiment of this application, please refer to Figure 2The automatic retractable luggage packing lock 100 further includes a guide roller 40 , one end of the winding belt 20 is wound around the synchronous belt 13 , and the other end is led out from the guide roller 40 .

[0048] It is understandable that the winding belt 20 is led out from the guide roller 40, which can change the direction of the pressure on the winding belt 20. No matter which direction the lock buckle 21 is pulled, the winding belt 20 can be pulled out through the guide roller 40.

[0049] In another embodiment of this application, please refer to Figure 2 The dual-wheel assembly 10 further includes a gear pair 50 with a reduction transmission ratio. The gear pair 50 is located between the second synchronous wheel 12 and the spring assembly 14 . The spring assembly 14 is connected to the second synchronous wheel 12 through the gear pair 50 .

[0050] It is understandable that the transmission ratio can be changed by a set of gear pairs 50 with a reduction transmission ratio, thereby reducing the structural size of the clockwork assembly 14, which is conducive to miniaturization.

[0051] In another embodiment of this application, please refer to Figure 2 The side surfaces of the first synchronous wheel 11 and the second synchronous wheel 12 are provided with special-shaped holes 19, through which the first synchronous wheel 11 and the second synchronous wheel 12 can be synchronously rotated by external force.

[0052] It is understandable that, after unlocking, in order to quickly shrink the wrapping belt 20, two special-shaped rods corresponding to the special-shaped holes 19 can be inserted into the special-shaped holes 19, and the two special-shaped rods rotate synchronously, thereby quickly shrinking the wrapping belt 20.

[0053] In another embodiment of this application, please refer to Figure 2 The automatic retractable luggage packing lock 100 further includes a positioning chip 60, which can send location information to a backend server in real time.

[0054] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
