Description

Technical Field

[0001] The present application relates to the field of luggage, and in particular to a lock and luggage. Background Art

[0002] A suitcase is a type of luggage. People often carry suitcases when traveling to increase their convenience during the trip. Existing suitcases usually include a main body, a front cover installed on one side of the suitcase main body, and a rear cover installed on the other side of the suitcase main body. The front cover and the suitcase main body, as well as the rear cover and the suitcase main body, are closed by zippers. This allows the suitcase to form different spaces to facilitate users to classify their belongings. While making it easier to take items, it also reduces the risk of users' private items, such as underwear, being exposed.

[0003] A suitcase with this structure is inconvenient because zippers at different positions need to be unlocked when taking out items from the suitcase. Therefore, in the prior art, patent publication number CN108979359A, entitled "A Combination Lock for Luggage Zippers," discloses an integrated dual-control combination lock, in which a knob is rotated to drive the lock cylinder in different directions, thereby unlocking different positions at both ends of the lock. This allows the zipper between the front cover and the luggage body, as well as the zipper between the rear cover and the luggage body, to be locked on the same lock, thereby improving the convenience of unlocking.

[0004] However, since the lock is integrated, the sizes of the rear cover and the front cover need to be basically similar so that different zippers can be placed on the same lock. If the size of the rear cover changes compared to the size of the front cover, the setting position of the zipper between the rear cover and the suitcase will also change, making it impossible to lock the zipper between the rear cover and the suitcase body, resulting in a poor range of applicability.

[0029] The following is combined with Figure 1-12 This application is described in further detail.

[0030] The present application discloses a lock and a bag. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , including a suitcase and a lock arranged on the suitcase, wherein the suitcase includes a main body 7, a front cover 8, a rear cover 10 and a fixed frame 9, wherein the front cover 8 is arranged on one side of the main body 7 and is closed with the main body 7 by a zipper, and the fixed frame 9 is fixedly arranged on the side of the main body 7 away from the front cover 8, and the rear cover 10 is arranged on the fixed frame 9, which makes the rear cover 10 and the fixed frame 9 form a storage space on the main body 7 that is different from the storage space between the front cover 8 and the main body 7, and the lock is arranged on the main body 7, the lock includes a long lock shell 1 and a lock core 2 installed in the lock shell 1, and a first unlocking mechanism 3 and a second unlocking mechanism 4 are respectively provided at both ends of the lock shell 1, wherein the first actuator 502 is a password lock in the embodiment of the present application, which is used to lock the zipper between the front cover 8 and the main body 7.

[0031] In other embodiments, the first unlocking mechanism 3 may also be a structure that unlocks by fingerprint, face or NFC.

[0032] The second unlocking mechanism 4 includes a driving block 401 and a toggle block 402, wherein the driving block 401 is arranged at the bottom of the lock cylinder 2, the toggle block 402 is slidably arranged in the lock shell 1 and can move in the lock shell 1 toward or away from the first unlocking mechanism 3, a toggle rod 4011 is provided on the lower surface of the driving block 401, and a slot 4021 for the toggle rod 4011 to be inserted is provided on the toggle block 402, the slot 4021 is a waist-shaped groove extending in a direction perpendicular to the length direction of the lock shell 1, when the lock cylinder 2 is unlocked, the toggle block 402 is slidably arranged in the lock shell 1 and can move in the lock shell 1 toward or away from the first unlocking mechanism 3, a toggle rod 4011 is provided on the lower surface of the driving block 401, and a slot 4021 for the toggle rod 4011 to be inserted is provided on the toggle block 402, and the slot 4021 is a waist-shaped groove extending in a direction perpendicular to the length direction of the lock shell 1. When rotating, the driving block 401 will rotate along with the lock core 2, thereby driving the toggle rod 4011 to rotate together. At this time, since the toggle rod 4011 is inserted into the slot 4021, it will drive the toggle block 402 to move in the lock shell 1 toward or away from the first unlocking mechanism 3. A first side lock 5 is also provided on the outside of the lock shell 1, and a traction rope 11 is provided between the first side lock 5 and the toggle block 402. The traction rope 11 is a steel rope, and the first side lock 5 is connected in series with the toggle block 402 through the traction rope 11.

[0033] Reference Figure 2 、 Figure 5 and Figure 6The first side lock 5 includes a fixed seat 501, a first actuator 502 and a locking drive 503, wherein the fixed seat 501 is set on the fixed frame 9, and the first actuator 502 and the locking drive 503 are respectively set in the fixed seat 501, and one end of the locking drive 503 is connected to the end of the traction rope 11 away from the toggle block 402. This makes it possible that when the toggle block 402 moves toward the direction close to the first unlocking mechanism 3 under the drive of the toggle rod 4011, the traction rope 11 is a steel wire rope and has no elasticity itself. Therefore, it will be straightened to pull the first unlocking mechanism 3 to slide relative to the first actuator 502 in the fixed seat 501.

[0034] Reference Figure 7 and Figure 8 , a driving portion 5031 is provided on the locking drive member 503, and the first actuator 502 includes a first mounting seat 5021, a first sliding block 5022 and a first plug-in block 5023. The first mounting seat 5021 is installed on the fixed seat 501, and the first plug-in block 5023 is arranged in the first mounting seat 5021 and can slide vertically in the first mounting seat 5021. When the first plug-in block 5023 is in a natural state, the end of the first plug-in block 5023 extends from the first mounting seat 5021, thereby realizing the locking between the rear cover 10 and the fixed frame 9; and the first sliding block 5022 is also installed in the first mounting seat 5021. The first sliding block 5022 can slide in the horizontal direction on the first mounting seat 5021. One end is inserted into the first insertion block 5023 in the first mounting seat 5021, and a first wedge surface 50221 is provided on the first sliding block 5022 to abut against the first insertion block 5023, and the driving portion 5031 can abut against the first sliding block 5022, so that when the locking driving member 503 slides in the fixed seat 501 under the traction of the traction rope 11, the driving portion 5031 on the locking driving member 503 can drive the first sliding block 5022 to move in the direction close to the first insertion block 5023, so that the first insertion block 5023 can move along the direction of the first wedge surface 50221 in the first mounting seat 5021, thereby realizing the retraction of the first insertion block 5023 on the first mounting seat 5021, so as to realize the unlocking between the fixed frame 9 and the rear cover plate 10.

[0035] When it is necessary to lock the rear cover 10 and the fixed frame 9 again, the lock cylinder 2 can be rotated toward its original position. At this time, the toggle block 402, which was originally close to the first unlocking mechanism 3, moves in the direction away from the first unlocking mechanism 3 under the drive of the toggle rod 4011, which makes the traction rope 11 between the toggle block 402 and the locking drive member 503 have a margin for the locking drive member 503 to move toward its original position. Subsequently, the first plug block 5023 descends along the first wedge surface 50221 under the action of its own gravity and extends from the first mounting seat 5021, thereby making the first sliding block 5022 move in the direction away from the first plug block 5023, and the first sliding block 5022 drives the locking actuator to reset by abutting against the driving part 5031. At this time, the traction rope 11 is in a straightened state again.

[0036] It is worth mentioning that a spring can be arranged in the first mounting seat 5021 so that the spring can abut against one end of the first plug block 5023 located in the first mounting seat 5021, thereby allowing the first plug block 5023 to quickly extend from the first mounting seat 5021 under the action of the spring force, and at the same time help the locking actuator to reset.

[0037] Furthermore, a second wedge surface 50222 is provided on the first sliding block 5022. The second wedge surface 50222 is arranged opposite to the first wedge surface 50221. A V-shaped groove for positioning the first plug-in block 5023 is formed between the first wedge surface 50221 and the second wedge surface 50222. This ensures that when the first plug-in block 5023 is in a natural state, the first wedge surface 50221 and the second wedge surface 50222 both abut against the first plug-in block 5023, thereby preventing the first sliding block 5022 from easily falling off the first plug-in block 5023.

[0038] Reference Figure 9 and Figure 10 A second spring 1001 and abutment block 1002 are also provided on the rear cover 10, and a limiting portion 1003 is provided at the middle position of the length of the abutment block 1002. One end of the second spring 1001 is fixedly provided on the rear cover 10, and the other end of the second spring 1001 is sleeved on one end of the abutment block 1002 close to the rear cover 10 and connected to the limiting portion 1003. This allows the rear cover 10 to be quickly popped off the fixing frame 9 under the action of the second spring 1001 after the rear cover 10 and the fixing frame 9 are unlocked, thereby facilitating the user to open the rear cover 10 from the fixing frame 9 to take items.

[0039] Reference Figure 3 , reference Figure 11 and Figure 12, Example 2 of the present application is further provided with a second side lock 6 on the basis of Example 1 of the present application, which can be connected in series with the locking actuator or the toggle block 402 through a traction rope 11. At this time, the traction rope 11 set on the toggle block 402 can be one or more. The first side lock 5 is set at the shorter border of the fixed frame 9, and the second side lock 6 is set at the longer border of the fixed frame 9. This makes it possible for the additional first side lock 5 to increase the number of locking positions between the rear cover plate 10 and the fixed frame 9 when the size between the fixed frame 9 and the rear cover plate 10 is large, thereby increasing the locking stability between the rear cover plate 10 and the fixed frame 9.

[0040] The second side lock 6 includes a second mounting seat 601, a second sliding block 602 and a second plug-in block 603, wherein the second mounting seat 601 is fixedly set on the longer frame of the fixed frame 9, the second plug-in block 603 is slidably set on the second mounting seat 601 and can slide horizontally relative to the second mounting seat 601 on the second mounting seat 601, and a first spring 6011 is further provided in the second mounting seat 601 for pushing one end of the second plug-in block 603 out of the second mounting seat 601. At this time, the second plug-in block 603 is used to achieve locking between the rear cover 10 and the fixed frame 9.

[0041] The second plug block 603 is also arranged on the second mounting seat 601 and can slide in the vertical direction relative to the second mounting seat 601. One end of the second sliding block 602 is connected to the traction rope 11, and the other end of the second sliding block 602 is inside the second mounting seat 601 and passes through the second plug block 603. A third wedge surface 6021 that abuts against the second plug block 603 is provided at the position of the second sliding block 602 below the second plug block 603. This enables the second sliding block 602 to move upward relative to the second plug block 603 under the traction of the traction rope 11, and the second plug block 603 can slide along the direction of the third wedge surface 6021, thereby allowing the second plug block 603 to retract on the second mounting seat 601. At this time, the first spring 6011 is compressed, thereby achieving unlocking between the rear cover 10 and the fixed frame 9.

[0042] When it is necessary to re-lock the rear cover 10 and the fixed frame 9, the lock cylinder 2 can be rotated toward its original position. At this time, the toggle block 402, which was originally close to the first unlocking mechanism 3, moves in the direction away from the first unlocking mechanism 3 under the drive of the toggle rod 4011, which will cause the traction rope 11 between the second slider and the locking drive member 503 or the second slider and the toggle block 402 to have a margin for the second slider to move toward its original position. At this time, the second sliding block 602 moves downward relative to the second plug block 603 under the action of its own gravity. At this time, the traction rope 11 is in a straightened state again, and the second plug block 603 is extended from the second mounting seat 601 again under the action of the elastic force of the first spring 6011, thereby realizing the locking between the rear cover 10 and the fixed frame 9.

[0043] It is worth mentioning that the number of second side locks 6 can be one or more, and the second sliding blocks 602 on each second side lock 6 can be unlocked by directly connecting the traction rope 11 to the toggle block 402. In addition, the second sliding block 602 can be pulled in series by connecting the traction rope 11 set on each second sliding block 602 to the locking drive member 503 of the first side lock 5 (that is, the locking drive member 503 is away from the end connected to the traction rope 11 on the toggle block 402).

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
