Technical Field

[0001] The present invention relates to the technical field of locks, and in particular to a combination lock and a bag having the combination lock. Background Art

[0002] In the prior art, in order to facilitate the use of luggage, people began to design luggage that can be opened and closed on both sides, so that the user can quickly open the luggage when facing either side of the luggage, without having to laboriously turn the luggage to find the side where the combination lock is installed. However, although such luggage that can be opened and closed on both sides is convenient for people to open the box body, even without opening the box cover, it is also convenient to open the box, but there are further requirements for the design of the combination lock installed on such luggage. The existing combination lock cannot meet the functional requirement of being able to be quickly opened from either side of the luggage.

[0003] In addition, the existing combination lock is unlocked by pressing buttons on the left and right sides of the lock body. Therefore, the lock body needs to be exposed on the outside of the bag to facilitate pressing the switch. Therefore, this combination lock that needs to be pressed from the side of the lock body is inconvenient to unlock. Moreover, the entire lock body is exposed on the surface of the bag, which is easy to cause bumps and damage to the lock body. Summary of the invention

[0004] The purpose of the present invention is to provide a combination lock to address the deficiencies in the prior art, which can solve the technical problems of inconvenient unlocking and the inability to quickly open a bag from either side. The present application also provides a bag that can solve the problem of exposed combination locks.

[0005] The objective of the present invention is achieved through the following technical solutions: The present application provides a combination lock, comprising a fixing plate, a lock body and a base, wherein the fixing plate is hinged to the side of the lock body through a hinge, the base is formed with a housing cavity for the lock body to be placed in, the left and right side walls in the housing cavity are formed with lock holes, the left and right sides of the lock body are provided with lock tongues that can slide back and forth along the length direction of the lock body; the lock body is also provided with a pusher that is exposed on the top surface of the lock body and is used to drive the lock tongue to slide, and the pusher can slide back and forth along the length direction of the lock body; when locking, the pusher is in the locking position, and the lock tongue is inserted into the lock hole of the base; when unlocking, the pusher is pushed to slide to the unlocking position, and the pusher drives the lock tongue to slide so that the lock tongue escapes from the lock hole of the base.

DETAILED DESCRIPTION

[0024] The present invention is further described in conjunction with the following examples.

[0025] An embodiment of a bag of the present invention is described by taking a bag without a zipper as an example. Figure 1As shown, the suitcase has a first box body 11 and a second box body 12, and the first box body 11 and the second box body 12 can be fastened together without a zipper. The front and rear sides of the suitcase are provided with password locks. In other embodiments, password locks can be provided only on the left and right sides of the suitcase, or password locks can be provided on the front, back, left and right sides of the suitcase. The specific selection and setting can be made according to actual needs.

[0026] Combination Figures 2 to 4 The combination lock comprises a fixing plate 3, a lock body, a base 71 and a bottom shell 72. The lock body comprises a lock shell 21 and a bottom plate 22 connected to the lock shell 21 by snapping. The fixing plate 3 is hinged to the side of the lock body through a hinge 30. In this embodiment, the hinge 30 is a rotating shaft. The base 71 is formed with a receiving cavity for the lock body to be placed. The left and right side walls of the receiving cavity are both formed with lock holes 70. The left and right sides of the lock body are both provided with lock tongues 100 that can slide back and forth along the length direction of the lock body. The lock tongue 100 extends to the outside of the lock shell 21. The lock body is also provided with a pusher 5 that is used to drive the lock tongue 100 to slide and is exposed on the top surface of the lock body. The pusher 5 can slide back and forth along the length direction of the lock body.

[0027] It should be noted that the fixing plate 3 is fixedly mounted on the top surface of the first box body 11, and the bottom shell 72 is fixedly mounted on the top surface of the second box body 12. Since the bottom shell 72 is fixedly mounted with the base 71, the bottom shell 72 is mounted on the inner side of the second box body 12, and the second box body 12 is clamped by the bottom shell 72 and the base 71 to achieve the fixation of the bottom shell 72, and the fixing plate 3 can be installed on the first box body 11 by the fixing method of the bottom shell 72. In this way, the accommodating cavity of the base 71 is embedded in the interior of the bag. When the lock body is buckled with the base 71, the lock body is placed in the accommodating cavity of the base 71, and the lock body is not completely exposed to the outside of the box body, which solves the problem that the password lock is exposed and easily damaged by collision. The password lock of this embodiment has two uses, which can be used as a hinge and a password lock. If the opposite sides of the bag are equipped with the password lock of this embodiment, when the two password locks are opened at the same time, the box can be used as a storage box, and it is convenient to open the box in places where there is no condition to open the lid.

[0028] Combination Figure 5 A mounting hole is provided in the middle of the lock tongue 100, and a mounting post 51 extends downward from the push-piece 5, which is inserted into the mounting hole. In this way, the push-piece 5 can drive the lock tongue 100 to slide.

[0029] The working process of the password lock of this embodiment is as follows: when locking, the pusher 5 is in the locked position, and the end of the lock tongue 100 is inserted into the lock hole 70 of the base 71. Since the lock tongue 100 buckles the base 71, the lock body cannot rotate around the rotation axis. When unlocking, the pusher 5 is pushed to slide to the unlocking position, and the pusher 5 drives the lock tongue 100 to slide so that the lock tongue 100 escapes from the lock hole 70 of the base 71. At this time, the lock body can rotate around the rotation axis to unlock. It can be seen that the password lock of this application can be used as a hinge and a password lock. When the password locks of this application are installed on both sides of the opposite sides of the luggage, one password lock is in a locked state, and the other password lock is in an unlocked state. The password lock in the locked state can act as a hinge, so that the luggage can be turned around its hinge 30 to open, that is, according to the actual situation, either side of the luggage can be turned over and opened; when the two password locks on both sides of the opposite sides of the luggage are opened at the same time, the box can be used as a storage box, and it is convenient to open the box even in places where there is no condition to open the lid.

[0030] In order to prevent theft, a password wheel assembly 4 and a clutch 9 are also provided in the lock housing. The clutch 9 can rotate relative to the lock housing. Figure 6 A rotation hole is provided in the middle of the clutch 9, and a vertically placed pin 94 is fixed in the lock shell. It can be understood that the inner top surface and the inner ground of the lock shell are both formed with a mounting tube for the pin to be inserted. The pin 94 is fixed inside the lock shell by interference fit, and the pin 94 is inserted into the rotation hole of the clutch 9, so that the clutch 9 can move in the height direction of the lock shell along the axial direction of the pin 94. Since the rotation is relative, as long as the clutch can slide in the height direction of the lock shell relative to the lock shell, in other embodiments, the pin 94 and the clutch 9 can be integrally formed, so that the whole formed by the two can rotate and move up and down relative to the lock shell. In addition, an elastic member 90 is provided between the clutch 9 and the lock shell to drive the clutch 9 to move upward. The elastic member 90 is a reset spring, and the reset spring is sleeved on the outer peripheral side of the rotating shaft below the clutch 9. The lock tongue 100 extends a rod toward the clutch 9, and a slot is provided on the rod. The slot is an open slot, and the rod can slide along the length direction of the slot. The clutch 9 extends a toggle portion 91 downward, and the toggle portion 91 is inserted into the slot, so that the rotation of the clutch 9 can be converted into the sliding of the lock tongue 100 along the length direction of the lock body.

[0031] It should be noted that the code wheel assembly 4 includes a retractable axle 41, the end of which abuts against the clutch 9, which is the same as the conventional code wheel assembly 4. If the code is correct, the axle 41 can retract, but if the code is wrong, the axle 41 cannot retract.

[0032] The working process of the password wheel assembly 4 of this embodiment is as follows: when locking, if the password is wrong, the wheel shaft 41 cannot move telescopically, and the wheel shaft 41 abuts against the clutch 9 to limit the rotation of the clutch 9, and the clutch 9 cannot rotate, thereby limiting the sliding of the lock, and achieving locking. When unlocking, if the password is correct, the external force pushes the pusher 5 to slide horizontally, and the horizontal sliding of the pusher 5 will drive the lock tongue 100 to slide in the unlocking direction, and the sliding of the lock tongue 100 will drive the clutch 9 to rotate. Since the wheel shaft 41 can move telescopically, the rotation of the clutch 9 is not restricted. When the clutch 9 rotates, the wheel shaft 41 will retract, and the lock tongue 100 can slide in the unlocking direction, thereby achieving unlocking.

[0033] Combination Figure 6 The lock housing is further provided with a lock core 6 which can rotate relative to the lock housing. The lock core 6 extends a pressing portion 61 outwardly. A groove 92 which is arranged obliquely upward is formed on one side of the clutch member 9 facing the lock core 6.

[0034] The working process of the lock core 6 of this embodiment is as follows: when locking, the lock core 6 rotates to the locking position, at which time, the pressing portion 61 of the lock core 6 separates from the groove 92 of the clutch block, and the clutch 9 abuts against the axle 41 to achieve locking. When unlocking, the lock core 6 is rotated to the unlocking position. During the rotation process, the pressing portion 61 of the lock core 6 slides into the groove 92 of the clutch 9, thereby gradually applying a downward pressure to the clutch 9 to move the clutch 9 downward until the clutch 9 and the end of the axle 41 are staggered in the height direction, and the axle 41 no longer hinders the clutch 9 from rotating. At this time, the lock can be unlocked by pushing the pusher 5.

[0035] To make the unlocked Figure 2 The lock body automatically pops out from the base 71. The lock shell is also provided with a top block 8 that can slide along the height direction of the lock shell. The top block 8 passes through the bottom surface of the lock shell. An unlocking spring 81 is provided between the top block 8 and the lock shell to drive the top block 8 to be ejected from the bottom of the lock shell.

[0036] The combination lock of this embodiment is unlocked by horizontal pushing, has good operating feel, and has a simpler and more compact structure. The push mechanism 5 is exposed on the top surface of the lock, which is more convenient to operate.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
