Description

A luggage lock that locks firmly

Technical field

The present invention relates to the technical field of luggage locks, and in particular to a luggage lock that locks firmly.

Background technique

With people's needs for work, travel, business trips and other travels, various types of bags have become more and more important in people's lives. People often put some valuables and information into bags for easy portability. Therefore, the safety and anti-theft of luggage have attracted more and more attention, and luggage locks have become an indispensable part of luggage.

In the prior art, a luggage lock includes a locking component, which includes a first lock hook and a second lock hook respectively installed on the two opening and closing sides of the luggage, and the two lock hooks engage and lock each other. Luggage locks also include operating parts (can be replaced by push buttons, knobs, etc.), locking mechanisms and transmission parts. The locking mechanism is a password lock, key cylinder or NFC. After unlocking the password of the locking mechanism or inserting the correct key, turn it or close it. Only after the field electric control induction is triggered can the restriction of the operating member be released. The operating member drives the first lock hook to rotate or slide through the transmission member, and is unlocked with the second lock hook to achieve unlocking.

For example, the Chinese patent document with publication number CN207749937U discloses a luggage lock and luggage. The luggage lock includes: a housing, a driving device, a transmission device, a limiting device, an ejection device, a lock hook, a control device and an auxiliary locking device; control device The device controls the driving device to push the transmission device to move according to the Bluetooth unlocking signal or the fingerprint unlocking signal, so that the transmission device drives the limit device away from the lock hook until the limit device unlocks the locked hook. At this time, the ejection device pops up the lock hook and limits it. The position device limits the position; the auxiliary locking device is connected to the limit device and is compressed with the movement of the transmission device. When the lock hook is pressed down to the ejection device to unlock the limit device, the auxiliary locking device pushes the limit device Move toward the locking hook until the stopper locks the locking hook. Since the luggage lock is opened through Bluetooth signals or fingerprint signals, the user does not need to remember the password. In addition, when the luggage lock is applied to the luggage, the user can open the luggage through the Bluetooth signal or fingerprint signal without having to remember the luggage password. This type of lock uses NFC near-field sensing to unlock.

Another example is the combination lock disclosed in the Chinese patent document with the publication number CN205012764U, which includes a central lock, a first side lock and a second side lock. The first side lock is located at both ends of the central lock, and the first side lock and the second side lock The transmission control between the two side locks is through the rotating block and the wire rope. The central control lock controls the opening and closing of the first side lock and the second side lock through the central control transmission mechanism in it. Among them, the central control lock and the first side lock The first lock catch and the second lock catch of the second side lock are fixed on the frame on one opening and closing side of the box. The first lock hook of the first side lock and the second lock hook of the second side lock are fixed on the other side of the box. Border on the opening and closing sides.

It can be seen from the above that all kinds of luggage locks are inseparable from the locking component. Some have lock hooks that match the zipper, and some have two sets of lock hooks that match. There are two existing technologies for the structure of two sets of lock hooks that match:

The first one is: the first lock hook is installed elastically and movable, maintaining the tendency of forward rotation and fastening. When the bag is closed, the second lock hook is inserted, and the second lock hook pushes the first lock hook to give way in the opposite direction. After being inserted into place, the first lock hook is forwardly reset and interlocked to achieve locking; when unlocking, the transmission member forcibly drives the first lock hook in the opposite direction and staggers with the second lock hook to achieve unlocking; the first lock hook of this structure passes through The spring is used to keep the lock locked, and the first lock hook must have room for movement. In the event of violent shaking (during shipping) or heavy falls or knocks, the first lock hook can easily passively overcome the elastic force and move to unlock, resulting in insufficient safety performance.

The second type is: the forward locking and reverse unlocking movements of the first lock hook are both achieved by pushing, that is, when the push is in the unlocking position, the first lock hook is in the unlocking state, and when the push is in the locking position, the first lock hook is in the unlocking state. The lock hook is in the locked state, and the usage process is: manual operation and push to the unlocking position → the first lock hook is opened and in the unlocking position → both opening and closing sides of the bag are closed while the second lock hook is inserted → manual operation is pushed to the locked position at the same time Drive the first lock hook to achieve locking. There is a problem: although the first lock hook of this structure is forcedly limited by the pusher, it is not easily unlocked by external force after being successfully locked; but when the pusher is in the unlocking position, after the two opening and closing sides of the bag are closed, the first lock hook The lock hook will not automatically engage the second lock hook, and the user cannot confirm whether the two lock hooks are hooked, or the two lock hooks are repulsed when the box is bulging with items, making it difficult to hook each other. There is a partial or complete lock. The hooks have no uncertainty in interlocking, low safety performance, inconvenient operation, and poor user experience. Especially for luggage locks with "one control and multiple openings", that is, a group of locking mechanisms in the middle that control multiple locking components, such as the luggage locks disclosed in the prior art cited above, because of the number of locking components. There are more than two, and it is not easy for the user to operate it during use, and it is even more difficult to observe whether the lock on the inside of the bag is fastened. Therefore, the bag locks with such locking components are in urgent need of improvement.

Detailed ways

The present invention will be described in detail below with reference to specific embodiments and drawings.

A securely locked luggage lock of this embodiment, as shown in Figures 1 to 7, includes a lock body 6. A central control mechanism 61 is provided in the middle of the lock body 6. The central control mechanism 61 includes a password component 611 and a key lock. The core 612 and the lock body 6 are also provided with an operating part 62. The operating part 62 is a push rod that can slide along the length direction of the lock body 6. The slide rod 63 is connected below the push rod. The slide rod 63 can slide along the length direction of the lock body 6. Arrangement, the operating part 62 is restricted by the central control mechanism 61. After entering the password in the password component 611 or inserting the correct key into the key lock cylinder 612 and turning it, that is, inputting the correct command, the restrictions on the operating part 62 can be released, and the manual Push the operating member 62 and the sliding rod 63. The above are common structures of existing luggage locks, and the luggage lock in this example also includes this basic structure.

In this embodiment, locking components are respectively provided at both ends of the lock body 6 and on the outside of the lock body 6. There are four sets of locking components in total. This type of lock is suitable for hard luggage. The two locking components on the lock body 6 are located at On one side of the bag, two locking components located outside the lock body are located on the other two sides of the bag to lock the three sides of the bag. The locking component located outside the lock body is an improved locking component A7. Its specific structure is:

The first lock hook 1 and the second lock hook 2 are respectively installed on the two opening and closing sides of the bag. The two can be locked together and separated to unlock. The first lock hook 1 is rotatably (swings within a certain range) installed on the lock. On the shell 3, a first elastic member (torsion spring) is provided in the middle of the first lock hook 1, so that the first lock hook 1 maintains the unlocking tendency, that is, the counterclockwise rotation in Figure 4.

The lock housing 3 is provided with a locking member 4. The middle part of the locking member 4 is rotatably connected to the lock housing 3. The locking member 4 is provided with a second elastic member (torsion spring), which keeps the locking member 4 close to the first elastic member. The trend of lock hook 1 is to rotate clockwise in Figure 4. A limiting protrusion 11 is provided on the side of the first lock hook 1. As shown in Figure 5, in the unlocked state, the end of the locking member 4 leaves the rotation path of the limiting protrusion 11, as shown in Figure 4, in the locked state. The stopper 4 resists the limiting protrusion 11 to limit the rotation of the first lock hook 1 .

In this embodiment, the first lock hook 1 is provided with a linkage part 12. When the bag is closed, the second lock hook 2 overcomes the force of the first elastic member and pushes against the linkage part 12 to drive the first lock hook 1 to rotate, causing the second lock hook 2 to rotate. The first lock hook 1 and the second lock hook 2 are in a locked state that interlocks with each other, and the locking member 4 follows to limit the rotation of the first lock hook 1 . Obviously, after the first lock hook 1 is pushed to the mutual interlocking position by the second lock hook 2, the locking member 4 is driven by the second elastic member to automatically push against the limiting protrusion 11 to limit the reverse direction of the first lock hook 1. Turn to lock. The linkage part 12 is a convex structure integrally formed on the first lock hook 1. In practice, the linkage part 12 can be in other shapes, as long as it can cooperate with the second lock hook 2 to drive the first lock hook 1 to engage with each other when the bag is closed. Can.

In this embodiment, the lock housing 3 is provided with a first blocking portion 31 that limits the swing range of the first lock hook 1 and a second blocking portion 32 that limits the swing range of the locking member 4, so that the first lock hook 1 and the locking member 4 Swing within the preset range.

In this embodiment, the lock housing 3 is provided with an unlocking component 5. When driven by an external force, the unlocking component 5 can drive the locking member to release the restriction on the first lock hook 1 and unlock the lock. Specifically, the unlocking assembly 5 includes a dialing block 51, an unlocking block 52 and a transmission member 53. The unlocking block 52 is slidably installed on the lock housing 3. The transmission member 53 is connected to the unlocking block 52 to drive the unlocking block 52 to slide. The transmission member 53 is a steel rope, one end of which is connected to the sliding rod 63, and the other end is connected to the unlocking block 52. When the operating member 62 and the sliding rod 63 move, they can drive the unlocking block 52 to slide forward and backward, which is the same as what is disclosed in the literature cited in the background art. The transmission is similar and will not be described in detail here. One end of the dialing block 51 is hinged to the lock housing 3, and the dialing block 51 is provided with a third elastic member (preferably a compression spring, which pushes up the dialing block 51, and may actually be a torsion spring installed on a hinged shaft), which makes The dialing block 51 maintains a tendency to be close to the locking member 4 and is elastically and floatingly mounted on the unlocking block 52. The unlocking block 52 is provided with a third blocking portion 521 that limits the rotation range of the dialing block 51. Between the third elastic member and the third blocking Under the interaction of the parts 521, the dial block 51 maintains the position as shown in Figure 2. When the transmission member 53 and the unlocking block 52 slide forward due to external force, they drive the dial 51 to drive the locking member 4 to rotate in the reverse direction to release the restriction on the first lock hook 1. When the unlocking block 52 is reset in the reverse direction, it floats to avoid the locking member 4. It can be seen that the unlocking component 5 in this example only realizes unlocking in one direction and has no effect on locking, achieving the effect of independent separation of locking and unlocking. In practice, if the unlocking component 5 is changed to a similar one-way unlocking structure, the basic purpose of being able to lock even in the unlocking position can be achieved.

Specifically, the dialing block 51 is provided with a barb 511. The barb 511 includes a hook body 5111 and a slant back 5112. When the unlocking block 52 slides forward under external force, it drives the hook body 5111 to drive the locking member 4; the unlocking block 52 is reset in the reverse direction. When the locking member 4 overcomes the force of the third elastic member and pushes against the inclined surface, the inclined surface plays a good guiding role.

In this embodiment, the locking components located at both ends of the lock body 6 are defined as the locking component B8, which includes a first locking hook 81 and a second locking hook 82 respectively installed on the two opening and closing sides of the bag. The two can interlock. When the lock is closed and separated to unlock, the middle part of the lock hook 81 is rotatably installed on the lock body 6. The lock body 6 is provided with a compression spring to exert force on the lock hook 81 to keep the lock hook 81 elastically locked. Trend, after inserting the lock hook 2 82, the lock hook 82 overcomes the elastic force and pushes the lock hook 1 81 away. After being buckled in place, the lock hook 81 elastically resets; after the central control mechanism 61 inputs the correct command, the control of the operating member 62 is released. The operating member 62 is controlled by an external force to drive the sliding rod 63 to slide, and then drives the lock hook 81 to rotate and unlock.

It should be added that in the luggage lock of this example, the central control mechanism 61 includes both a password component 611 and a key lock cylinder 612. The actual lock can be changed to have only one of the unlocking methods. The operating member 62 in this example is push-made, but may actually be changed to a button or a knob. These are replacements of conventional technologies in the field of luggage locks, and will not be described in detail here.

In this example, the innovative locking component A is located outside the lock body 6, while the ordinary locking component B is located on the lock body. In practice, the order of these positions can be interchanged. For example, if the improved locking component A is changed to be located on the lock body, The ordinary locking component B can also be located outside the lock body. This example includes improved locking component A and ordinary locking component B. In practice, all improved locking components A can be used. This example shows a "one control, multiple openings" luggage lock in which a central control mechanism controls multiple locking components. In fact, it can be changed to a "one control, one opening" or "one control, two openings" luggage lock. All in all, as long as the luggage lock adopts the improved locking component A, it is within the scope of the claims.
