Technical Field

[0001] The present application belongs to the technical field of luggage locks, and specifically relates to a dual-function combination lock for luggage. Background Art

[0002] Luggage combination locks are a type of lock commonly used to protect personal belongings such as luggage and bags. Unlike traditional key locks, luggage combination locks use a number combination to unlock without the need for a key.

[0003] For example, the application with the publication number CN210483283U discloses a password lock that is easy for customs to open, including a shell, belonging to the technical field of password locks, a password mechanism is installed inside the shell, a push block is installed on the right side of the password mechanism, a sliding groove is opened on the top of the shell, the push block is slidably connected to the sliding groove, a lock core is installed inside the push block, and the lock core is connected with a connecting block. When the utility model is in use, after the customs inserts the key, the key is turned counterclockwise, the key drives the lock core to rotate counterclockwise, the lock core drives the connecting block to move to the left, at this time the connecting rod moves to the left, and drives the card block to move downward through the card slot, so that the locking rod moves downward, and then the password lock is opened. Compared with the existing password lock, the new password lock that is easy for customs to open only needs to turn the key to open it during customs inspection, the operation steps are simple, and it is more convenient to use.

[0004] However, with the development of society, single-layer luggage combination locks cannot meet the daily lives of consumers, and the use of multiple combination locks cannot achieve convenience. Utility Model Content

[0005] The purpose of the present application is to provide a dual-function luggage combination lock in order to solve the problem that the single-layer luggage combination lock cannot meet the daily life of consumers, and the use of multiple combination locks cannot achieve convenience.

[0006] The technical solution adopted in this application is as follows: a dual-function combination lock for luggage, comprising a main shell, the inner surface of the main shell is movably connected with a locking sleeve at the reinforcement rib, the outer surface of the locking sleeve is provided with a cut surface corresponding to the reinforcement rib, the inner surface of the locking sleeve is movably connected with an axle, the outer surface of the axle is movably connected with an unlocking connector, the inner surface of the unlocking connector is movably connected with a customs lock, the outer surface of the customs lock is movably connected with a first displacement rod, and the outer surface of the customs lock corresponding to the first displacement rod is movably connected with a second displacement rod.

[0007] By adopting the above technical scheme, the main shell is the main body of the password lock, and the three reinforcing ribs on the panel of the lock main body are parallel to the cross section of the locking sleeve, which is in the open state. The locking sleeve is locked at any other rotation angle. There is a convex point on the inner circle of the locking sleeve, and it is in the open and movable state when it coincides with the long groove on the wheel axle. When the locking sleeve is rotated at any angle, the convex point rotates in the circular groove of the wheel axle, and when it is misaligned with the long groove on the wheel axle, it is in the locked state and cannot move axially. The unlocking connecting piece conveniently drives the displacement of the wheel axle while ensuring that the customs lock is always in a vertical state. At the same time, the unlocking connecting piece is made of tough material to ensure that the customs lock can be deformed normally when rotating. The first displacement rod is mainly responsible for the switch displacement of the lock body position, and the second displacement rod ensures the switch displacement of the other layer of the lock body position, thereby ensuring that one password lock drives the switch of two layers of luggage. When the password lock is locked, the customs lock is driven to rotate by the customs key to open the luggage, thereby avoiding breaking and dismantling and causing the luggage to be unable to continue to be used.

[0008] In a preferred embodiment, a reinforcing rib is fixedly connected to the inner surface of the main shell, and a code wheel is movably connected to the outer surface of the locking sleeve.

[0009] By adopting the above technical solution, the reinforcing ribs are used to limit the main parts of the combination lock, and the locking sleeve limits the displacement of the wheel axle when the combination wheel rolls to a position that does not correspond to the groove.

[0010] In a preferred embodiment, a first security-changing component is movably connected to the outer surface of one end of the wheel shaft away from the customs lock, and a second security-changing component is movably connected to the outer surface of the first security-changing component.

[0011] By adopting the above technical solution, the first and second security-changing pieces are separated by axle squeezing, so that there is no limit on each other in the open state, and the password wheel can rotate. When the corresponding password is changed, the axle rebounds, and the first and second security-changing pieces are tightly attached, and the corresponding groove position needs to be used to complete the release of the limit.

[0012] In a preferred embodiment, a displacement reference part is fixedly connected to the inner surface of the main shell corresponding to the first sealing part, and a limiting groove is fixedly connected to the inner surface of the main shell corresponding to the displacement reference part.

[0013] By adopting the above technical solution, the displacement reference member and the limit groove ensure the stability of the entire running position of the wheel axle, and at the same time provide a stable limit for the combination lock.

[0014] In a preferred embodiment, a return spring is fixedly connected to the outer surface of the wheel axle, and an unlocking push button is provided on the outer surface of the unlocking connector.

[0015] By adopting the above technical solution, the return spring ensures the cycle of the wheel axle moving back and forth, and the unlocking push button is convenient for the user to move.

[0016] In a preferred embodiment, locking grooves are fixedly connected to the inner surfaces of both sides of the main housing, and limit switch components are arranged on the inner surfaces of the locking grooves.

[0017] By adopting the above technical solution, the lock buckle groove ensures the insertion of the buckle grooves of the two layers of lock body, and the limit switch component facilitates the control of the buckle, thereby achieving a switching effect.

[0018] In a preferred embodiment, the outer surface of the main shell is movably connected to the lower shell, the inner surface of the lower shell is movably connected to a limit ring corresponding to the customs lock, and the outer surface of the lower shell is movably connected to a pushing member corresponding to the limit ring.

[0019] By adopting the above technical solution, the lower shell seals the lock as a whole to ensure stable operation. The limit ring ensures the displacement of the customs lock when the locking sleeve and the password wheel are locked. When the pusher is pressed, it drives the other side of the limit ring to rotate the limit ring, thereby driving the rotation of the customs lock.

[0020] In a preferred embodiment, a reset rod is movably connected to the inner surface of the lower shell, and a plurality of threaded holes are fixedly connected to the inner surface of the lower shell.

[0021] By adopting the above technical solution, the reset rod ensures that the back-and-forth displacement of the lock can be restored to the original position, and the threaded hole facilitates the connection of the main shell and the lower shell, which is convenient for fixing.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0023] In this application,

[0024] 1. When the three convex reinforcing ribs on the lock body panel are parallel to a straight edge of the outer circle of the locking sleeve axis, it is in the open state. When the locking sleeve axis rotates to any angle, it is in the locked state.

[0025] 2. There is a convex point on the inner circle of the locking sleeve shaft core. When it coincides with the long groove on the wheel axle, it is in an open and movable state. When the locking sleeve shaft core rotates at any angle, the convex point rotates in the circular groove of the wheel axle shaft core. When it is misaligned with the long groove on the wheel axle, it is in a locked state and cannot move axially;

[0026] 3. There is an interchangeable number mechanism at the end of the axle, and the first and second password-changing components control the positioning of the shaft and the changing of the password. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in combination with the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] Example:

[0036] Reference Figure 1-6 A dual-function combination lock for luggage comprises a main shell 1, a locking sleeve 3 is movably connected to the inner surface of the main shell 1 at a reinforcing rib 2, a section is arranged on the outer surface of the locking sleeve 3 corresponding to the reinforcing rib 2, a wheel axle 6 is movably connected to the inner surface of the locking sleeve 3, an unlocking connector 5 is movably connected to the outer surface of the wheel axle 6, a customs lock 7 is movably connected to the inner surface of the unlocking connector 5, a first displacement rod 15 is movably connected to the outer surface of the customs lock 7, and a second displacement rod 17 is movably connected to the outer surface of the customs lock 7 corresponding to the first displacement rod 15.

[0037] When the locking sleeve 3 is rotated at any other angle, it is in a locked state. When the locking sleeve 3 is rotated at any angle, it is in an open state. When the locking sleeve 3 is coincident with the long groove on the wheel axle 6, it is in an open and movable state. When the locking sleeve 3 is rotated at any angle, the convex point rotates in the annular groove of the wheel axle 6, and when it is misaligned with the long groove on the wheel axle, it is in a locked state and cannot move axially. The unlocking connector 5 facilitates the displacement of the wheel axle 6 while ensuring that the customs lock 7 is always in a vertical state. At the same time, the unlocking connector 5 is made of tough material to ensure that the customs lock 7 can be deformed normally when rotating. The first displacement rod 15 mainly controls the switch displacement of the lock body position, and the second displacement rod 17 ensures the switch displacement of the other layer of the lock body position, thereby ensuring that one password lock drives the switch of two layers of luggage. When the password lock is locked, the customs lock 7 is driven to rotate by the customs key to open the luggage, avoiding the luggage from being broken and dismantled and causing it to be unable to be used.

[0038] Reference Figure 1-6 The inner surface of the main shell 1 is fixedly connected with a reinforcing rib 2, and the outer surface of the locking sleeve 3 is movably connected with a password wheel 4.

[0039] The reinforcing rib 2 is used to limit the main parts of the combination lock, and the locking sleeve 3 limits the displacement of the wheel shaft 6 when the combination wheel 4 rolls to a position not corresponding to the groove.

[0040] Reference Figure 1-4 The outer surface of one end of the axle 6 away from the customs lock 7 is movably connected with a first security-changing piece 11, and the outer surface of the first security-changing piece 11 is movably connected with a second security-changing piece 12.

[0041] The first and second cipher-changing pieces 11 and 12 are separated by squeezing the axle 6, so that they are not limited to each other in the open state, and the code wheel 4 can rotate. When the corresponding code is changed, the axle 6 rebounds, and the first and second cipher-changing pieces 11 and 12 are pressed tightly together, and the corresponding groove position needs to be used to complete the release of the limit.

[0042] Reference Figure 1-4 A displacement reference part 13 is fixedly connected to the inner surface of the main shell 1 corresponding to the first sealing part 11, and a limiting groove 14 is fixedly connected to the inner surface of the main shell 1 corresponding to the displacement reference part 13.

[0043] The displacement reference member 13 and the limit groove 14 ensure the stability of the entire running position of the axle 6 and provide a stable limit for the combination lock.

[0044] Reference Figure 1-4 A return spring 19 is fixedly connected to the outer surface of the axle 6, and an unlocking push button 20 is provided on the outer surface of the unlocking connecting piece 5.

[0045] The return spring 19 ensures the cycle of the wheel shaft 6 to be moved back and forth, and the unlocking push button 20 is convenient for the user to move.

[0046] Reference Figure 1-4 The inner surfaces of both sides of the main housing 1 are fixedly connected with locking grooves 18 , and the inner surfaces of the locking grooves 18 are provided with limit switch components 16 .

[0047] The lock buckle groove 18 ensures the insertion of the buckle grooves of the two layers of the lock body, and the limit switch member 16 facilitates the control of the buckle to achieve a switch effect.

[0048] Reference Figure 3 The outer surface of the main shell 1 is movably connected to the lower shell 9, the inner surface of the lower shell 9 is movably connected to the limit ring 8 corresponding to the customs lock 7, and the outer surface of the lower shell 9 is movably connected to the limit ring 8 with a pushing member 10.

[0049] The lower shell 9 seals the lock as a whole to ensure stable operation. The limit ring 8 ensures the displacement of the customs lock 7 when the locking sleeve 3 and the password wheel 4 are locked. When the pusher 10 is pressed, it drives the other side of the limit ring 8 to rotate the limit ring 8, thereby driving the rotation of the customs lock 7.

[0050] Reference Figure 3 A reset rod 21 is movably connected to the inner surface of the lower shell 9, and a plurality of threaded holes 22 are fixedly connected to the inner surface of the lower shell 9.

[0051] The reset rod 21 ensures that the lock can be restored to its original position after reciprocating displacement, and the threaded hole 22 facilitates the connection and fixation of the main housing 1 and the lower housing 9.

[0052] The implementation principle of the embodiment of the dual-function luggage lock of the present application is as follows:

[0053] When in use, the device code wheel 4 rolls to the corresponding groove position and the unlocking push knob 20 can be moved left and right, and the first displacement rod 15 and the second displacement rod 17 are pulled together to drive the limit switch 16 to open the corresponding layers of the bag buckles. When the code wheel 4 rolls to other positions, the locking sleeve 3 is stuck to prevent the wheel axle 6 from moving, thereby blocking the unlocking push knob 20 from moving left and right. When the locking sleeve 3 and the code wheel 4 are locked due to problems, the customs lock is inserted into the unlocking push knob 20 to rotate the customs lock 7, so that in the corresponding limit groove of the main shell 1, the customs lock 7 rotates and drives the first displacement rod 15 and the second displacement rod 17 to move through squeezing, and the locks on both sides are opened, avoiding the need to break open the luggage when the locking sleeve 3 and the code wheel 4 are locked, which is convenient and practical.

[0054] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
