Description

Technical Field

[0001] This utility model relates to the field of luggage technology, and more specifically to a combination lock for luggage. Background Technology

[0002] A suitcase, also known as a travel case or rolling suitcase, is a type of luggage carried when traveling to store belongings. Most suitcases on the market today are equipped with combination locks to enhance security. A typical suitcase consists of a body, combination lock, a handle assembly, wheels, and a carrying handle attached to the body. The body usually comprises two halves connected on one side by a coupling or hinge. When the two halves are closed, the zipper is usually engaged, and then the zipper pull is inserted into the combination lock. This combination lock restricts the position of the zipper pull, thus sealing the suitcase.

[0003] Currently, when closing a suitcase, you need to pull both zippers together first, then insert the zipper pull into the combination lock to secure it. However, when inserting the zipper pull into the combination lock, you need to align it with the lock's latch and press it down to secure it. Pressing the zipper pull requires considerable force and is time-consuming, requiring a good amount of light to align it properly. This can cause pain for some users and make it inconvenient to use.

[0012] In summary, this utility model has the following beneficial effects:

[0013] 1. This utility model involves pulling a pull ring, which moves a pull rod, thereby moving a pressing plate. Rotating the pull ring then moves a first limiting block, restricting the position of the pressing plate. The zipper head is then placed directly into the combination lock, laid flat, and the pull ring is rotated again, causing the pull rod to rotate and the first limiting block to move. A second spring then moves the pressing plate, causing the connecting rod and ball bearings to rotate on the zipper head. As the ball bearings move on the zipper head, they cause the connecting rod to slide inside the pressing plate, compressing the first spring and allowing the ball bearings to move above the zipper head, thus pressing it down and restricting its position, thereby sealing the suitcase. This method of sealing reduces the time required to align the zipper head, improving efficiency, and eliminates the need to press the zipper head, reducing the difficulty of sealing the suitcase.

[0014] 2. This utility model uses a handle to move a transmission rod, which in turn moves a pull block, which in turn moves a second slide bar, thereby compressing a third spring and separating the limiting gear from the storage cylinder. This prevents the second slide bar from rotating when the combination wheel is rotating, thus allowing the combination to be changed. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] This embodiment discloses a combination lock for a suitcase, such as... Figures 1 to 6 As shown, the device includes a combination lock 1. Three indicator lights 2 are fixedly connected to the top of the combination lock 1. A pressing assembly is provided inside the combination lock 1. The pressing assembly includes a pressing plate 3 that is slidably connected inside the combination lock 1. The bottom of the pressing plate 3 is slidably connected to the bottom of the inner cavity of the combination lock 1. The pressing plate 3 passes through the combination lock 1. Three locking blocks 9 are fixedly connected to the top of the pressing plate 3. A pull rod 4 is rotatably connected inside the pressing plate 3. A first limiting plate 5 is fixedly connected to the end of the pull rod 4. A pull ring 8 is slidably connected inside the pull rod 4. Two first limiting blocks 7 are fixedly connected to the outside of the pull rod 4. A stabilizing block 6 is slidably connected to the outside of the pull rod 4. The outside of the stabilizing block 6 is fixedly connected to the inside of the combination lock 1. A connecting rod 10 is slidably connected inside the pressing plate 3. A ball bearing 11 is rotatably connected inside the connecting rod 10. A first spring 12 is fixedly connected between the outside of the connecting rod 10 and the inside of the pressing plate 3.

[0024] Pulling the pull ring 8 moves the pull rod 4, which in turn moves the pressing plate 3. Rotating the pull ring 8 then moves the first limiting block 7, restricting the position of the pressing plate 3. The zipper head is then placed directly into the combination lock 1 and laid flat. Rotating the pull ring 8 again moves the pull rod 4, which in turn moves the first limiting block 7. The second spring 15 then moves the pressing plate 3, causing the connecting rod 10 and the ball bearing 11 to rotate on the zipper head. As the ball bearing 11 moves on the zipper head, it causes the connecting rod 10 to slide inside the pressing plate 3, compressing the first spring 12. This allows the ball bearing 11 to move above the zipper head, pressing it down and restricting its position, thus sealing the suitcase. This method of sealing reduces the time required to align the zipper head, improving efficiency, and eliminates the need to press the zipper head, reducing the difficulty of sealing the suitcase.

[0025] The combination lock 1 is equipped with a recovery component, which includes a first slide rod 13 that is slidably connected inside the locking block 9. A support frame 14 is fixedly connected to the end of the first slide rod 13. The bottom of the support frame 14 is fixedly connected to the bottom of the inner cavity of the combination lock 1. A second spring 15 is fixedly connected between the outer side of the locking block 9 and the outer side of the support frame 14.

[0026] The second spring 15 pushes the locking block 9, causing the locking block 9 to slide outside the first slide bar 13, and then the locking block 9 slides to the outside of the chuck 16.

[0027] The combination lock 1 is equipped with a locking component, which includes a chuck 16 that is slidably connected to the outside of the chuck block 9. A slide cylinder 17 is fixedly connected inside the chuck 16, and the bottom of the slide cylinder 17 is rotatably connected to the bottom of the inner cavity of the combination lock 1.

[0028] The locking assembly also includes a second slide rod 18 slidably connected inside the slide cylinder 17. Two second limiting blocks 19 are fixedly connected to the outside of the second slide rod 18. The second limiting blocks 19 pass through the slide cylinder 17 and are slidably connected. A third spring 20 is fixedly connected between the bottom of the second slide rod 18 and the bottom of the inner cavity of the slide cylinder 17. A second limiting plate 22 is fixedly connected to the top of the second slide rod 18.

[0029] The movement of the second limiting plate 22 drives the movement of the second slide bar 18, thereby compressing the third spring 20;

[0030] The rotation of the slide cylinder 17 causes the chuck 16 to rotate, preventing the chuck block 9 from entering the chuck 16 and thus preventing the pressing plate 3 from moving. This restricts the position of the zipper head through the pressing plate 3, thereby sealing the suitcase.

[0031] The second slide bar 18 is provided with a pressing component on its outer side. The pressing component includes a limiting gear 21 fixedly connected to the outer side of the second slide bar 18. A storage tube 23 is slidably connected to the outer side of the limiting gear 21. The storage tube 23 passes through the combination lock 1 and is slidably connected. A combination wheel 24 is fixedly connected to the top of the storage tube 23.

[0032] By rotating the password wheel 24, the storage cylinder 23 is driven to rotate, which in turn drives the limit gear 21 to rotate, thereby driving the second slide bar 18 to rotate.

[0033] The second slide bar 18 is provided with an adjustment component on its outer side. The adjustment component includes a pull block 25 fixedly connected to the outer side of the second slide bar 18. Two transmission rods 26 are fixedly connected to the top of the pull block 25. The transmission rods 26 pass through the combination lock 1 and are slidably connected. A handle 27 is fixedly connected to the top of the transmission rods 26.

[0034] By pressing the handle 27, the transmission rod 26 is moved, which in turn moves the pull block 25, and then moves the second slide rod 18.

[0035] The outer side of the second slide rod 18 is slidably connected to the inside of the storage tube 23, and the outer side of the second limiting plate 22 is slidably connected to the inside of the storage tube 23.

[0036] The sliding distance of the second slide bar 18 can be limited by the sliding of the second limiting plate 22 inside the storage tube 23.

[0037] The working principle and usage process of this utility model are as follows: By pulling the pull ring 8, the pull rod 4 is moved, which in turn moves the pressing plate 3. Then, the pull ring 8 is rotated, which in turn moves the first limiting block 7, thereby restricting the position of the pressing plate 3. Then, the zipper head is placed directly into the combination lock 1. The zipper head is then laid flat. Next, the pull ring 8 is rotated, which in turn rotates the pull rod 4, thereby moving the first limiting block 7. Then, the second spring 15 moves the pressing plate 3, which in turn causes the connecting rod 10 and the ball bearing 11 to rotate on the zipper head. When the ball bearing 11 moves on the zipper head, it causes the connecting rod 10 to slide inside the pressing plate 3, thereby compressing the first spring 12. This allows the ball bearing 11 to move above the zipper head, thereby pressing the zipper head and restricting its position, thus sealing the suitcase. Sealing the suitcase in this way reduces the time required to align the zipper head, thereby improving efficiency. It also eliminates the need to press the zipper head, thus reducing the difficulty of sealing the suitcase.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model should be included within the protection scope of the present utility model.
