Description

Technical Field

[0001] This invention relates to a pointer-type combination lock for bags and related products, which can be applied to products such as bags, doors, and safes. Background Technology

[0002] Currently, combination locks are widely used in products such as bags, doors, and safes. Mechanical combination locks include push-button and rotary dial types. Rotary dial locks are further divided into single-dial (used in safes) and multi-dial (used in bags). Single-dial locks use a forward and reverse rotation method to unlock, offering strong security and high difficulty in cracking. However, their disadvantages include complex password settings, the need to memorize the password during unlocking leading to errors, and the inability to identify the source of the error, requiring restarting. The password is not displayed visually. A major drawback of single-dial locks (used in safes) is the inconvenience of changing the password, as any combination cannot be changed. Due to the fixed connection between the drive disc and the drive shaft, changing the password involves inserting pins into different holes. Since there are only a fixed number of pin holes, the password can only be changed within a fixed set, typically 7-8 sets. These sets are fixed at the factory and cannot be changed, essentially meaning a lock has only a fixed number of keys. To achieve a large number of possible passwords, a limited number of combinations must be set. Each lock has a different structure, meaning the corresponding positions (angles) of the locking disc drive boss and notch are different for each lock. This prevents the same combination code from opening multiple locks. Existing pointer-type combination locks all use this principle. However, current technologies such as those published under CN20278826U, CN101956494B, and CN101956494A lack practicality. Changing the combination requires opening the lock body and moving the pointer, which is very inconvenient and cannot be considered a practical product. Multi-disc locks are simple to use and display the unlocking code directly, but they have weak security and are very easy to crack. For someone skilled in the art, the combination code can be cracked in minutes, almost negating the purpose of the combination lock. This is because the internal locking disc notch can be seen through the gaps in the rotating disc, and the locking disc notch corresponds to the unlocking code. To solve the above problems and defects, a solution is needed that combines the advantages of both types of locks while avoiding their disadvantages, that is, simultaneously achieving high security and intuitive display of the unlocking code. Summary of the Invention

[0003] To address the aforementioned shortcomings, the present invention aims to provide a pointer-type combination lock for bags and a pointer-type combination lock that uses a single-disc design and displays the unlocking combination intuitively through a pointer, thereby perfectly solving these shortcomings. To achieve the aforementioned effect and function, the present invention adopts the following technical solution.

[0004] A pointer-type combination lock bag, comprising a bag body and a pointer-type combination lock, the pointer-type combination lock including an unlocking key, a latch, an unlocking component, a clutch, a dial, a dial, pointer one, pointer two, lock disc one, lock disc two, drive shaft one, and drive shaft two. The dial is provided with scale marks and / or symbol marks. Pointer one is connected to drive shaft two, drive shaft two is connected to lock disc two, pointer two is connected to drive shaft one, drive shaft one is connected to lock disc one, drive shaft one is provided with a first engaging boss, and drive shaft two is provided with a second engaging boss. The first engaging boss and the second engaging boss... The two transmission shafts are intermittently engaged. The first transmission shaft is equipped with a transmission phase tooth, and the second transmission shaft is equipped with a transmission phase tooth. The first locking disc is equipped with a locking disc phase tooth, and the second locking disc is equipped with a locking disc phase tooth. The first transmission phase tooth and the first locking disc phase tooth are separated or engaged by a clutch, and the second transmission phase tooth and the second locking disc phase tooth are separated or engaged by a clutch. The latch is connected to the unlocking key, and the unlocking key is connected to the unlocking assembly. The turntable is configured as a toothed ring or a watch cover. The combination of pointer one and pointer two pointing to the scale marks or symbols on the dial by the clockwise and reverse rotation of the turntable constitutes the unlocking code.

[0005] A pointer-type combination lock includes an unlocking key, a latch, an unlocking component, a clutch, a dial, a dial, a pointer one, a pointer two, a lock disc one, a lock disc two, a drive shaft one, and a drive shaft two. The dial is provided with scale markings and / or symbol markings. Pointer one is connected to drive shaft two, drive shaft two is connected to lock disc two, pointer two is connected to drive shaft one, drive shaft one is connected to lock disc one, drive shaft one is provided with a first engaging boss, and drive shaft two is provided with a second engaging boss. The first engaging boss and the second engaging boss engage intermittently. The transmission phase gear is set as follows: transmission phase gear 1 is set as follows; transmission phase gear 2 is set as follows; lock disc 1 is set as follows; lock disc 2 is set as follows; transmission phase gear 1 and lock disc phase gear 1 are disengaged or engaged by a clutch; transmission phase gear 2 and lock disc phase gear 2 are disengaged or engaged by a clutch; the latch is connected to the unlocking key; the unlocking key is connected to the unlocking component; the turntable is set as a toothed ring or watch cover; the combination of pointer 1 and pointer 2 pointing to the scale marks or symbols on the dial by the clockwise and counterclockwise rotation of the turntable constitutes the unlocking code.

[0006] The gear ring connects to the planetary gears, and the planetary gears connect to the sun gear. The rotation of the gear ring drives the second transmission shaft to rotate.

[0007] The watch cover is fixedly connected to the drive shaft, and the rotation of the watch cover drives the drive shaft to rotate.

[0008] The first and second transmission shafts are arranged concentrically and are driven by intermittent transmission through the first and second engagement bosses.

[0009] The symbol or mark can be a number, letter, or text pattern.

[0010] The technical solution of this invention is: using two or more pointers in conjunction with the dial, with the multiple pointers pointing to a combination of scale marks and / or symbol marks on the dial to display the password.

[0011] The beneficial effects of this invention are: because multiple pointers are used in conjunction with the dial, and the combination of multiple pointers pointing to the dial's scale marks and / or symbol marks displays the password, the number of password combinations is exponentially related to the number of pointers, allowing for the combination of multiple passwords. Each additional pointer increases the number of password combinations by an order of magnitude. The password is displayed intuitively, has high confidentiality, and is extremely difficult to crack.

Implementation

[0028] Exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These exemplary embodiments are provided so that those skilled in the art can clearly understand the present invention and implement it based on the description herein. The drawings and specific embodiments are not intended to limit the scope of the invention, which is defined by the appended claims.

[0029] The pointer-type combination lock can be applied to products such as bags, room doors, and cabinet doors. Combination locks are relatively common and mature products. For those skilled in the art, their general internal structure is easy to understand and conceive of. The conventional parts will not be described in detail. This embodiment only describes the new inventive points of the present invention in detail.

[0030] Example 1:

[0031] like Figure 1 , 4As shown in Figures 5 and 9, a pointer-type combination lock bag is provided. The pointer-type combination lock bag consists of a bag body (29) and a pointer-type combination lock (30). The pointer-type combination lock is installed on the bag body. The pointer-type combination lock includes an unlocking key (8), a latch (9), an unlocking component (13), a clutch (7), a dial (3), a first pointer (4), a second pointer (5), a first lock disc (11), a second lock disc (20), a first drive shaft (17), and a second drive shaft (12). The dial is provided with scale marks and / or symbol marks. The first pointer is connected to the second drive shaft, the second drive shaft is connected to the second lock disc, the second pointer is connected to the first drive shaft, and the first drive shaft is connected to the lock disc. 1. The first drive shaft is provided with a first engagement boss, and the second drive shaft is provided with a second engagement boss. The first engagement boss and the second engagement boss are intermittently engaged. The first drive shaft is provided with a first drive phase tooth, and the second drive shaft is provided with a second drive phase tooth. The first lock disc is provided with a first lock disc phase tooth, and the second lock disc is provided with a second lock disc phase tooth. The first drive phase tooth and the first lock disc phase tooth are separated or engaged by a clutch. The second drive phase tooth and the second lock disc phase tooth are separated or engaged by a clutch. The latch is connected to the unlocking key, and the unlocking key is connected to the unlocking component. The combination of pointers 1 and 2 pointing to the scale marks or symbols on the dial by the forward and reverse rotation of the first drive shaft is the unlocking password. When unlocking, rotating the gear ring drives the planetary gears, which in turn drive the sun gear, which in turn drives the gear that is rigidly connected to the transmission shaft two. The transmission shaft two then drives the transmission shaft one. The forward and reverse rotation of the transmission shaft one causes the pointer one and pointer two to point to the scale marks or symbols on the dial, which is the combination of the unlocking code.

[0032] The dial is preferably set in a watch face format. The three hands can combine to form tens of thousands of passwords, such as the hour, minute, and second as the unlock code. The hour hand has 12 markings, and the minute and second hands have 60 markings, so there are 12 * 60 * 60, a total of 43,200 passwords, which is very difficult to crack. However, the hour hand does not only point to the hour. In fact, the hour hand also has 60 markings, so the three hands have 60 * 60 * 60, a total of 216,000 passwords. In actual use, each hand is set to 24 markings, that is, the hour hand marks one marking every half hour, and the minute and second hands are similar. For bag products, two hands can have 24 * 24, a total of 576 passwords, so the three hands have 24 * 24 * 24, a total of 13,824 passwords. There is a sufficient total number of passwords, high confidentiality, and great difficulty in cracking. For traditional mechanical safe combination locks, the scale lines and numbers cannot intuitively display the complete password. The unlocking method usually uses a three-level combination with an indicator arrow. First, turn the lock in one direction to a certain number or scale, and remember that number. Then turn it in the opposite direction to a certain number or scale, and remember that number again. The previous number is no longer displayed. Then turn it clockwise again to a certain number or scale, and the previous two numbers are also no longer displayed. If you enter the wrong number, you cannot know whether the first step or the second step is wrong, and you have to start unlocking from the beginning. It is very troublesome to use. This invention perfectly solves this defect. When unlocking, first rotate the first pointer in one direction to align it with a certain value (e.g., the hour pointer aligns with a certain time scale). Then rotate the second pointer in the opposite direction to align it with a certain value (e.g., the minute pointer aligns with a certain minute scale). At this time, the first unlock password will not change and will remain unchanged. Then rotate the third pointer in the forward direction to align it with a certain value (e.g., the second pointer aligns with a certain second scale). At this time, the first and second unlock passwords will not change and will remain unchanged. The entire unlock password is displayed intuitively after setting. If a digit is wrong, you only need to go back and modify the position of that pointer.

[0033] Working principle, such as Figure 4 , 5 As shown in Figure 9, the pointer and the lock disc are respectively connected to the sun gear and the drive shaft. If another set of pointers, lock discs and drive shafts are added, the number of passwords will increase by one level. In fact, three pointers are enough to meet the needs. Too many pointers will increase the structural complexity and volume, which is unnecessary. Drive shaft one and drive shaft two are arranged concentrically. One end of drive shaft two (12) is connected to needle one (4) and the other end is connected to lock disc two (20). One end of drive shaft one (17) is connected to pointer two (5) and the other end is connected to lock disc one (11). Notch two (24) is set on lock disc two (20), and notch one (16) is set on lock disc one (11). First, rotate the gear ring in one direction (e.g., clockwise) to drive the sun gear to rotate until the engagement boss 2 (21) engages with the engagement boss 1 (25), further driving the drive shaft 1 (17) to rotate. The pointer 2 (5) connected to one end of the drive shaft 1 (17) is linked with the lock disc 1 (11) connected to the other end. The pointer 2 (5) corresponds to the notch 1 (16). At this time, the value indicated by the pointer 2 (5) is the first unlocking code. Then, rotate the gear ring in the opposite direction (counterclockwise) to drive the engagement boss 2 (21) and engagement boss 1 (25) to engage with the engagement boss 1 (25). When the transmission shaft is disengaged, only the second transmission shaft (12) rotates while the first transmission shaft (17) remains stationary. When the second transmission shaft (12) is rotated to a certain position, the first pointer (4) corresponds to the second notch (24). The value indicated by the first pointer (4) is the second unlock code. If another pointer is added, the first password is set by rotating it clockwise once, the second password is set by rotating it counterclockwise once, and the third password is set by rotating it clockwise once. The combination of the values ​​indicated by the three pointers is the unlock code.

[0034] like Figure 2 As shown, the dial is provided with scale marks and / or symbol marks, which can be Arabic numerals, Roman numerals, or letters, with Arabic numerals or Roman numerals being the most common.

[0035] like Figure 2 As shown, the pointer is set to two or more, and the combination of the scale marks and / or symbol marks pointed to by the multiple pointers displays the password. The figure shows 1:20, which is the current password.

[0036] like Figure 5 , 6 As shown in Figure 7, the password change method is set as a button or a rotary knob. Most bags use the button type. When the combination lock is in the unlocked state, the password change device is restricted by the unlocking component in the unlocked state. Press the clutch (7), and the password change device will separate the lock disc (20, 11) from the second drive shaft (12) and the first drive shaft (17). At this time, rotate the gear ring to drive the pointer to set a new password. Release the clutch (7), and the lock disc (20, 11) will re-engage with the second drive shaft (12) and the first drive shaft (17). At this time, the notch (16, 24) corresponds to the value pointed to by the new pointer (4, 5), which is the new unlock code. Buttons or knobs can be placed on the outside or inside. Generally, they are placed on the outside for easy use, while they can be placed on the inside for higher confidentiality and security. The principle is to separate the lock disc from the pointer and change the phase of the notch and the pointer. A reset spring is set at the rear end of the lock disc. Under the action of the spring, the lock disc and the pointer re-engage, thus changing the unlocking code.

[0037] like Figure 9As shown, the number of phase teeth (22, 23, 28, 31) is set according to the number of cipher sets used at level 1 to ensure accurate phase correspondence. Otherwise, the cipher values ​​can be subdivided infinitely, the phase transformation has no series, the fault tolerance is poor, and the use is difficult.

[0038] like Figure 2 As shown, the unlocking key is set as a toggle block or a rotating handle. Generally, a toggle block is set on a bag, and a rotating handle is set on a door. The principle is to unlock the latch by toggle or rotate. A lock cylinder can also be set, which can be unlocked by a key. For example, the customs lock commonly used on bags can be unlocked by a key regardless of whether the password is correct or not. A lock cylinder can also be set on a door to prevent forgetting the password. It can also be unlocked by a key. The principle is the same as that of the customs lock on bags, that is, the connection between the unlocking component (13) and the unlocking key (8) is released, and the unlocking component loses its restrictive effect on the unlocking device.

[0039] Example 2:

[0040] like Figure 10 , 11 As shown in 12 or 13, the drive shaft 1 (17) and the watch cover (26) are integrated. The drive shaft 1 is directly driven by the watch cover. The pointer 2 (5) is directly fixed on the drive shaft 1. The extension end (32) of the drive shaft 1 is part of the drive shaft 1. The extension end (32) of the drive shaft 1 is rigidly connected to the drive shaft 1 (17) by screws. At the same time, the watch cover is connected to the face cover (1). It can rotate without falling off. The extension end of the drive shaft is connected to the lock disc 1 (11). The drive shaft 2 (12) is driven by the engagement boss 1 (25) set on the extension end of the drive shaft. The drive shaft 2 is connected to the lock disc 2 (20). The combination of the scale marks or symbols on the dial is the unlocking code when the drive shaft 1 rotates forward and reverses.

[0041] like Figure 5 As shown, when notch one (16) and notch two (24) are aligned with the unlocking component (13), the unlocking key (8) can be turned to drive the latch (9) to unlock. Otherwise, the lock plate prevents the unlocking component from moving, the unlocking key is locked, and it cannot be unlocked.

[0042] like Figure 14 As shown, a watch cover positioning bead (34) is set below the watch cover (26) to control the number of rotation levels of the watch cover (e.g., 24 levels means that each rotation is 15 degrees). Each rotation corresponds to the corresponding time, preventing misalignment and increasing the feel of rotation.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
